Change Log for PCRE2
--------------------
Before the move to GitHub, this was the only record of changes to PCRE2. Now
there is also the log of commit messages.
Internal changes which are not visible to clients of the library are mostly not
listed here.
Version 10.45 05-February-2025
------------------------------
1. (#418) Change 6 of 10.44 broke 32-bit tests because pcre2test's reporting of
memory size was changed to the entire compiled data block, instead of just the
pattern and tables data, so as to align with the new length restriction.
Because the block's header contains pointers, this meant the pcre2test output
was different in 32-bit mode. A patch by Carlo reverts to the previous state
and makes sure that any limit set by pcre2_set_max_pattern_compiled_length()
also avoids the internal struct overhead.
2. (#416, #622) Updates to build.zig.
3. (#427, et al.) Various fixes to pacify static analyzers.
4. (#428) Add --posix-pattern-file to pcre2grep to allow processing of empty
patterns through the -f option, as well as patterns that end in space
characters, for compatibility with other grep tools.
5. (4fa5b8bd) Fix a bug in the fuzz support quantifier-limiting code. It ignores
strings of more than 5 digits because they are necessarily numbers greater than
65535, the largest legal quantifier. However, it wasn't ignoring non-significant
leading zeros.
6. (6d82f0cd) The case-independent processing of the letter-matching Unicode
properties Ll, Lt, and Lu have been changed to match Perl (which changed a while
ago). When caseless matching is in force, all three of these properties are now
treated as Lc (cased letter).
7. (#433) The pcre2_jit_compile() function was updated by the addition of a new
option PCRE2_JIT_TEST_ALLOC which, if called with a NULL first argument, tests
not only the availability of JIT, but also its ability to allocate executable
memory. Update pcre2test to use this support to extend the -C option.
8. (75b1025a) The code for parsing Unicode property descriptions for \p and \P
been changed as follows:
. White space etc. before ^ in a negated value such as \p{ ^L } was not being
ignored.
. The code wouldn't have worked if PCRE2 was compiled for UTF-8 support
within an EBCDIC environment. Possibly nobody does this any more, but it
should now work.
. The documentation of the syntax of what can follow \p and \P has been
updated.
9. (1c24ba01) There was an error in the table of lengths for parsed items for
the OPTIONS item, but fortuitously it could never have actually bitten. While
fixing this, some other code that could never be obeyed was discovered and
removed.
10. (674b6640) Removed some incorect optimization code from DFA matching that
has been there since PCRE1, but has just been found to cause a no match return
instead of a partial match in some cases. It involves partial matching when (*F)
is present so is unlikely to have actually affected anyone.
11. (b0f4ac17) Tidy the wording and formatting of some pcre2test error messages
concerned with bad modifiers. Also restrict single-letter modifier sequences to
the first item in a modifier list, as documented and always intended.
12. (1415565c) An iterator at the end of many assertions can always be
auto-possessified, but not at the end of variable-length lookbehinds. There was
a bug in the code that checks for such a lookbehind; it was looking only at the
first branch, which is wrong because some branches can be fixed length when
others are not, for example (?<=AB|CD?). Now all branches are checked for
variability.
13. (ead08288) Matching with pcre2_match() could give an incorrect result if a
variable-length lookbehind was used as the condition in a conditional group.
The condition could erroneously be treated as true if a branch matched but
overran the current position. This bug was in the interpreter only; matching
with JIT was correct.
14. (#443) Split out the sljit sub-project into a "Git submodule". Git users
must now run `git submodule init; git submodule update` after a Git checkout, or
the build will fail due to missing files in deps/sljit.
15. (#441) Add a new error code (PCRE2_ERROR_JIT_UNSUPPORTED) which is yielded
for unsupported jit features.
16. (#444) Fix bug in 'first code unit' and 'last code unit' optimization
combined with lookahead assertions.
17. (#445, #447, #449, #451, #452, #459, #563) Add a new feature called scan
substring. This feature is a new type of assertion which matches the content of
a capturing block to a sub-pattern.
18. (#450) Improvements to 'first code unit' / 'starting code units'
optimisation.
19. (#455) Many, many improvements to the JIT compiler.
20. Item 43 of 10.43 was incomplete because it addressed only \z and not \Z,
which was still misbehaving when matching fragments inside invalid UTF strings.
21. (d29e7290) Octal escapes of the form \045 or \111 were not being recognized
in substitution strings, and if encountered gave an error, though the \o{...}
form was recognized. This bug is now fixed.
22. (#463, #487) Fix 1 byte out-of-bounds read when parsing malformed limits
(e.g. LIMIT_HEAP)
23. Many improvements to test infrastructure. Many more platforms and
configurations are now run in Continuous Integration, and all the platforms now
run the full test suite, rather than a partial subset.
24. (#475) Implement title casing in substitution strings using Perl syntax.
25. (#478, #504) Disallow \x if not followed by { or a hex digit.
26. (#473) Implements Python-style backrefs in substitutions.
27. (#472) Fix error reporting for certain over-large octal escapes.
28. (#482) Fix parsing of named captures in replacement strings, allowing
non-ASCII capture names to be used.
29. (#477, #474, #488, #494, #496, #506, #508, #511, #518, #524, #540) Many
improvements to parsing and optimising of character classes.
30. (#483, #498) Add support for \g<n> and $<name> to replacement strings.
31. (#470) Add option flags PCRE2_EXTRA_NO_BS0 and PCRE2_EXTRA_PYTHON_OCTAL.
32. (#471) Add new API function pcre2_set_optimize() for controlling which
optimizations are enabled.
33. (#491) Adds $& $` $' and $_ to substitution replacements, as well as
interpreting \b and \v as characters.
34. (#499) Add option PCRE2_EXTRA_NEVER_CALLOUT to disable callouts.
35. (#503, #513) Update Unicode support to UCD 16.
36. (#512, #618, #638) Add new function pcre2_set_substitute_case_callout() to
allow clients to provide a custom callback with locale-aware case
transformation.
37. (#516) Fix case-insensitive matching of backreferences when using the
PCRE2_EXTRA_CASELESS_RESTRICT option.
38. (#519) In pcre2grep, add $& as an alias for $0
39. (c9bf8339, #534) Updated perltest.sh to enable locale setting.
40. (#521) Add support for Turkish I casefolding, using new options
PCRE2_EXTRA_TURKISH_CASING, and added pre-pattern flags (*TURKISH_CASING) and
(*CASELESS_RESTRICT).
41. (#523, #546, #547) Add support for UTS#18 compatible character classes,
using the new option PCRE2_ALT_EXTENDED_CLASS. This adds '[' as a metacharacter
within character classes and the operators '&&', '--' and '~~', allowing
subtractions and intersections of character classes to be easily expressed.
42. (#553, #586, #596, #597) Add support for Perl-style extended character
classes, using the syntax (?[...]). This also allows expressing subtractions and
intersections of character classes, but using a different syntax to UTS#18.
43. (#554) Fixed a bug in JIT affecting greedy bounded repeats. The upper limit
of repeats inside a repeated bracket might be incorrectly checked.
44. (#556) Fixed a bug in JIT affecting caseful matching of backreferences. When
utf is disabled, and dupnames is enabled, caseless matching was used even
if caseful matching was needed.
45. (f34fc0a3) Fixed a bug in pcre2grep reported by Alejandro Colomar
<alx@kernel.org> (GitHub issue #577). In certain cases, when lines of above and
below context were contiguous, a separator line was incorrectly being inserted.
46. (#594) Fix a small (one/two byte) out-of-bounds read on invalid UTF-8 input
in pcre2grep.
47. (#370) Fix the INSTALL_MSVC_PDB CMake flag.
48. (#366) Install cmake files in prefix/lib/cmake/pcre2 rather than
prefix/cmake. The new CMake flag PCRE2_INSTALL_CMAKEDIR allows customising this
location.
49. (#624, #626, #628, #632, #639, #641) Reduce code size of generated JIT code
for repeated character classes.
50. (#623) Update the Bazel build files.
Version 10.44 07-June-2024
--------------------------
1. If a pattern contained a variable-length lookbehind in which the first
branch was not the one with the shortest minimum length, and the lookbehind
contained a capturing group, and elsewhere in the pattern there was another
lookbehind that referenced that group, the pattern was incorrectly compiled,
leading to unpredictable results, including crashes in JIT compiling. An
example pattern is: /(((?<=123?456456|ABC)))(?<=\2)/
2. Further updates to the oss-fuzz support:
(a) Limit quantifiers for groups and classes to be no more than 10. This
avoids very long JIT compile times that happen in some cases when groups
are replicated for quantification, and very long match times when
classes contain a lot of non-ascii characters.
(b) Added PCRE2_EXTENDED_MORE to the list of allowed options.
(c) Arranged for text error messages to be shown in 16-bit and 32-bit modes.
(d) Made the output in standalone mode more readable.
(e) General code tidies.
(f) Limit the size of compiled patterns to 10MB (see 6 below).
(g) Do not run JIT on patterns whose compiled length is greater than 200K
bytes because this takes a long time, causing oss-fuzz to time out.
(h) Avoid compiling or matching twice with the same options (this could
happen if the input didn't set any options).
3. Increase the maximum length of a name for a group from 32 to 128 because
there is a user for whom 32 is too small.
4. Cause pcre2test to output a message when pcre2_jit_compile() gives an error
return if either jitverify or info is specified.
5. Some auxiliary files for building under OpenVMS that were contributed by
Alexey Chupahin have been installed.
6. Added pcre2_set_max_pattern_compiled_length() to limit the size of compiled
patterns.
7. There was a bug in the implementation of \X caused by my (PH) misreading or
misunderstanding one of the grapheme sequence breaking rules in Unicode Annex
#29. A break should occur between two characters with the Extended Pictographic
break property unless a zero-width joiner intervenes. PCRE2 was not insisting
on the ZWJ, causing \X to match more than it should. See GitHub issue #410.
8. Avoid compilation issues with proprietary compilers in UNIX since 10.43.
Version 10.43 16-February-2024
------------------------------
1. The test program added by change 2 of 10.42 didn't work when the default
newline setting didn't include \n as a newline. One test needed (*LF) to ensure
that it worked.
2. Added the new freestanding POSIX test program to the ManyConfigTests script
in the maint directory (overlooked in 2 below). Also improved the selection
facilities in that script, and added a test with JIT in a non-source directory,
fixing an oversight that would have made such a test fail before.
3. Added pcre2_get_match_data_heapframes_size() and related pcre2test flags
to allow for finer control of the heap used when pcre2_match() without JIT is
used and the match_data might be reused. This began as PR #191, but has had
further refinement and documentation edits.
4. Applied PR #181, which tidies some casts in pcre2_valid_utf.c.
5. Applied PR #184, which avoids overflow issues with the heap limit
(introduced in 10.41/9).
6. Applied PR #192, which changes the timing units for pcre2test from
milliseconds to microseconds. This is more useful for modern CPUs.
7. Applied PR #193, which makes the requirement for C99 explicit in
configure.ac and CMakeLists.txt.
8. Fixed a bug in pcre2test when a ridiculously large string repeat required a
stupid amount of memory. It now gives a clean realloc() failure error.
9. Updates to restrict the interaction between ASCII and non-ASCII characters
for caseless matching and items like \d:
(a) Added PCRE2_EXTRA_CASELESS_RESTRICT to lock out mixing of ASCII and
non-ASCII when matching caselessly. This is also /r in pcre2test and
(?r) within patterns.
(b) Added PCRE2_EXTRA_ASCII_{BSD,BSS,BSW,POSIX} and corresponding (?aD) etc
in patterns and /a in pcre2test.
(c) Corresponding updates to pcre2test.
10. Unicode has been updated to 15.0.0.
11. The Python scripts and ucptest.c in maint have been updated (a) a minor
change needed for 9(a) above; (b) fix bugs in ucptest,
12. Integer overflow testing is now centralized in a new function.
13. Made PCRE2_UCP the default in UTF mode in pcre2grep, and added new options
--case-restrict and --no-ucp.
14. In the debugging printint module (which is normally only linked into
pcre2test), avoid the use of a variable called "not" because that's deprecated
in C and forbidden in C++. Also rewrite some code to avoid a goto into a block
that bypassed its initialization (though it didn't actually matter).
15. More minor code adjustments to avoid using reserved C++ words as variable
names ("new" and "typename") and another jump that bypassed an (irrelevant)
initialization.
16. Merged a pull request that removed pcre2_ucptables.c from the list of files
to compile in NON-AUTOTOOLS-BUILD because it is #included in pcre2_tables.c.
Also adjusted the BUILD.bazel and build.zig files, which had the same issue. At
the same time, fixed a typo in the Bazel file.
17. Add PCRE2_EXTRA_ASCII_DIGIT to allow [:digit:] to be kept on sync with \d
even in UCP mode.
18. Fix an invalid match of ascii word classes when invalid utf is enabled.
19. Add a --posix-digit to pcre2grep for compatibility with GNU grep, and
other tools that prefer the POSIX compatible unicode definition for \d.
20. Report the bit width of the library in use by pcre2test for usability.
21. A pathological pattern conversion test could result in a string longer than
the available input buffer. Cause such a test to fail.
22. Add a check that forces a compiler error if PCRE2_CODE_UNIT_WIDTH is not 8,
16, or 32 when compiling any of the library modules.
23. Update pcre2_compile() to treat a NULL pattern with zero length as an empty
string.
24. Add support for limited-length variable-length lookbehind assertions, with
default maximum length 255 characters (same as Perl) but with a function to
adjust the limit.
25. Applied pull request #262, which updates the zig configuration, and #278
which fixes a bug with out-of-source-tree CMake build testing.
26. Add support for LoongArch to JIT.
27. Fixed a bug in pcre2_match() in the code for handling the vector of
backtracking frames on the heap, which caused a heap overflow if *LIMIT_HEAP
restricted an attempt to extend to less than the frame size. Generally tidy up
the code for extending the heap frames vector. This fixes GitHub issue #275.
28. Update pcre2_fuzzsupport.c to avoid clang sanitize complaint about shifting
left by 16 when there are non-zeros in the top 16 bits.
29. Perl 5.34.0 changed the meaning of (for example) {,3} which did not used to
be treated as a quantifier. Now it is interpreted as {0,3} and PCRE2 has
changed to match. Note that {,} is still not a quantifier.
30. Perl allows spaces and/or horizontal tabs after { or before } in all items
that use braces, and also before or after the comma in quantifiers. PCRE2 now
does the same, except for \u{...}, which is recognized only when
PCRE2_EXTRA_ALT_BSUX is set. This an ECMAScript, non-Perl compatible,
extension, so PCRE2 follows ECMAScript rather than Perl.
31. Applied pull request #300 by Carlo, which fixes #261. The bug was that
pcre2_match() was not fully resetting all captures that had been set within a
(possibly recursive) subroutine call such as (?3).
32. Changed the meaning of \w (and its synonyms) in UCP mode to match Perl. It
now matches characters whose general categories are L or N or whose particular
categories are Mn (non-spacing mark) or Pc (combining punctuation). The latter
includes underscore.
33. Changed the meaning of [:xdigit:] in UCP mode to match Perl. It now also
matches the "fullwidth" versions of the hex digits. Just like it is done for
[:digit:], PCRE2_EXTRA_ASCII_DIGIT can be used to keep this class ASCII only
without affecting other POSIX classes.
34. GitHub PR305 fixes a potential integer overflow in pcre2_dfa_match().
35. Updated handling of \b and \B in UCP mode to match the changes to \w in 32
above because \b and \B are defined in terms of \w.
36. Within a pattern (?aT) and (?-aT) set and reset the PCRE2_EXTRA_ASCII_DIGIT
option, and (?aP) also sets (?aT) so that (?-aP) disables all ASCII
restrictions on POSIX classes.
37. If PCRE2_FIRSTLINE was set on an anchored pattern, pcre2_match() and
pcre2_dfa_match() misbehaved. PCRE2_FIRSTLINE is now ignored for anchored
patterns.
38. Add a test for ridiculous ovector offset values to the substring extraction
functions.
39. Make OP_REVERSE use IMM2_SIZE for its data instead of LINK_SIZE, for
consistency with OP_VREVERSE.
40. In some legacy environments with a pre C99 snprintf, pcre2_regerror could
return an incorrect value when the provided buffer was too small.
41. Applied pull request #342 which adds sanity checks for ctype functions and
locks out any accidental sign-extension.
42. In the 32-bit library, in non-UTF mode, a quantifier that followed a
literal character with a value greater than or equal to 0x80000000u caused
undefined behaviour.
43. \z was misbehaving when matching fragments inside invalid UTF strings.
44. Implement --group-separator and --no-group-separator for pcre2grep.
45. Fix \X matching in 32 bit mode without UTF in JIT.
46. Fix backref iterators when PCRE2_MATCH_UNSET_BACKREF is set in JIT.
47. Refactor the handling of whole-pattern recursion (?0) in pcre2_match() so
that its end is handled similarly to other recursions. This has altered the
behaviour of /|(?0)./endanchored which was previously not right.
48. Improved the test for looping recursion by checking the last referenced
character as well as the current character. This allows some patterns that
previously triggered the check to run to completion instead of giving the loop
error.
49. In 32-bit mode, the compiler looped for the pattern /[\x{ffffffff}]/ when
PCRE2_CASELESS and PCRE2_UCP (but not PCRE2_UTF) were set. Fixed by not trying
to look for other cases for characters above the Unicode range.
50. In caseless 32-bit mode with UCP (but not UTF) set, the character
0xffffffff incorrectly matched any character that has more than one other case,
in particular k and s.
51. Fix accept and endanchored interaction in JIT.
52. Fix backreferences with unset backref and non-greedy iterators in JIT.
53. Improve the logic that checks for a list of starting code units -- positive
lookahead assertions are now ignored if the immediately following item is one
that sets a mandatory starting character. For example, /a?(?=bc|)d/ used to set
all of a, b, and d as possible starting code units; now it sets only a and d.
54. Fix incorrect class character matches in JIT.
55. In pcre2test, ensure pcre2_jit_match() is used when jitfast is used with
substitution testing.
56. Insert omitted setting of subject length in match data at the end of
pcre2_jit_match().
57. Implemented PCRE2_DISABLE_RECURSELOOP_CHECK for pcre2_match() to enable
some apparently looping recursions to run to completion and therefore match the
JIT behaviour. With this set, real loops will eventually get caught by match or
heap limits or run out of resource.
58. AC did a lot of work on pcre2_fuzzsupport.c to extend it to 16-bit and
32-bit libraries and to compare JIT and non-JIT matching.
Version 10.42 11-December-2022
------------------------------
1. Change 19 of 10.41 wasn't quite right; it put the definition of a default,
empty value for PCRE2_CALL_CONVENTION in src/pcre2posix.c instead of
src/pcre2posix.h, which meant that programs that included pcre2posix.h but not
pcre2.h failed to compile.
2. To catch similar issues to the above in future, a new small test program
that includes pcre2posix.h but not pcre2.h has been added to the test suite.
3. When the -S option of pcre2test was used to set a stack size greater than
the allowed maximum, the error message displayed the hard limit incorrectly.
This was pointed out on GitHub pull request #171, but the suggested patch
didn't cope with all cases. Some further modification was required.
4. Supplying an ovector count of more than 65535 to pcre2_match_data_create()
caused a crash because the field in the match data block is only 16 bits. A
maximum of 65535 is now silently applied.
5. Merged @carenas patch #175 which fixes #86 - segfault on aarch64 (ARM),
6. The prototype for pcre2_substring_list_free() specified its argument as
PCRE2_SPTR * which is a const data type, whereas the yield from
pcre2_substring_list() is not const. This caused compiler warnings. I have
changed the argument of pcre2_substring_list_free() to be PCRE2_UCHAR ** to
remove this anomaly. This might cause new warnings in existing code where a
cast has been used to avoid previous ones.
Version 10.41 06-December-2022
------------------------------
1. Add fflush() before and after a fork callout in pcre2grep to get its output
to be the same on all systems. (There were previously ordering differences in
Alpine Linux).
2. Merged patch from @carenas (GitHub #110) for pthreads support in CMake.
3. SSF scorecards grumbled about possible overflow in an expression in
pcre2test. It never would have overflowed in practice, but some casts have been
added and at the some time there's been some tidying of fprints that output
size_t values.
4. PR #94 showed up an unused enum in pcre2_convert.c, which is now removed.
5. Minor code re-arrangement to remove gcc warning about realloc() in
pcre2test.
6. Change a number of int variables that hold buffer and line lengths in
pcre2grep to PCRE2_SIZE (aka size_t).
7. Added an #ifdef to cut out a call to PRIV(jit_free) when JIT is not
supported (even though that function would do nothing in that case) at the
request of a user who doesn't even want to link with pcre_jit_compile.o. Also
tidied up an untidy #ifdef arrangement in pcre2test.
8. Fixed an issue in the backtracking optimization of character repeats in
JIT. Furthermore optimize star repetitions, not just plus repetitions.
9. Removed the use of an initial backtracking frames vector on the system stack
in pcre2_match() so that it now always uses the heap. (In a multi-thread
environment with very small stacks there had been an issue.) This also is
tidier for JIT matching, which didn't need that vector. The heap vector is now
remembered in the match data block and re-used if that block itself is re-used.
It is freed with the match data block.
10. Adjusted the find_limits code in pcre2test to work with change 9 above.
11. Added find_limits_noheap to pcre2test, because the heap limits are now
different in different environments and so cannot be included in the standard
tests.
12. Created a test for pcre2_match() heap processing that is not part of the
tests run by 'make check', but can be run manually. The current output is from
a 64-bit system.
13. Implemented -Z aka --null in pcre2grep.
14. A minor change to pcre2test and the addition of several new pcre2grep tests
have improved LCOV coverage statistics. At the same time, code in pcre2grep and
elsewhere that can never be obeyed in normal testing has been excluded from
coverage.
15. Fixed a bug in pcre2grep that could cause an extra newline to be written
after output generated by --output.
16. If a file has a .bz2 extension but is not in fact compressed, pcre2grep
should process it as a plain text file. A bug stopped this happening; now fixed
and added to the tests.
17. When pcre2grep was running not in UTF mode, if a string specified by
--output or obtained from a callout in a pattern contained a character (byte)
greater than 127, it was incorrectly output in UTF-8 format.
18. Added some casts after warnings from Clang sanitize.
19. Merged patch from cbouc (GitHub #139): 4 function prototypes were missing
PCRE2_CALL_CONVENTION in src/pcre2posix.h. All function prototypes returning
pointers had out of place PCRE2_CALL_CONVENTION in src/pcre2.h.*. These
produced errors when building for Windows with #define PCRE2_CALL_CONVENTION
__stdcall.
20. A negative repeat value in a pcre2test subject line was not being
diagnosed, leading to infinite looping.
21. Updated RunGrepTest to discard the warning that Bash now gives when setting
LC_CTYPE to a bad value (because older versions didn't).
22. Updated pcre2grep so that it behaves like GNU grep when matching more than
one pattern and a later pattern matches at an earlier point in the subject when
the matched substrings are being identified by colour or by offsets.
23. Updated the PrepareRelease script so that the man page that it makes for
the pcre2demo demonstration program is more standard and does not cause errors
when processed by lexgrog or mandb -c (GitHub issue #160).
24. The JIT compiler was updated.
Version 10.40 15-April-2022
---------------------------
1. Merged patch from @carenas (GitHub #35, 7db87842) to fix pcre2grep incorrect
handling of multiple passes.
2. Merged patch from @carenas (GitHub #36, dae47509) to fix portability issue
in pcre2grep with buffered fseek(stdin).
3. Merged patch from @carenas (GitHub #37, acc520924) to fix tests when -S is
not supported.
4. Revert an unintended change in JIT repeat detection.
5. Merged patch from @carenas (GitHub #52, b037bfa1) to fix build on GNU Hurd.
6. Merged documentation and comments patches from @carenas (GitHub #47).
7. Merged patch from @carenas (GitHub #49) to remove obsolete JFriedl test code
from pcre2grep.
8. Merged patch from @carenas (GitHub #48) to fix CMake install issue #46.
9. Merged patch from @carenas (GitHub #53) fixing NULL checks in matching and
substituting.
10. Add null_subject and null_replacement modifiers to pcre2test.
11. Add check for NULL subject to POSIX regexec() function.
12. Add check for NULL replacement to pcre2_substitute().
13. For the subject arguments of pcre2_match(), pcre2_dfa_match(), and
pcre2_substitute(), and the replacement argument of the latter, if the pointer
is NULL and the length is zero, treat as an empty string. Apparently a number
of applications treat NULL/0 in this way.
14. Added support for Bidi_Class and a number of binary Unicode properties,
including Bidi_Control.
15. Fix some minor issues raised by clang sanitize.
16. Very minor code speed up for maximizing character property matches.
17. A number of changes to script matching for \p and \P:
(a) Script extensions for a character are now coded as a bitmap instead of
a list of script numbers, which should be faster and does not need a
loop.
(b) Added the syntax \p{script:xxx} and \p{script_extensions:xxx} (synonyms
sc and scx).
(c) Changed \p{scriptname} from being the same as \p{sc:scriptname} to being
the same as \p{scx:scriptname} because this change happened in Perl at
release 5.26.
(d) The standard Unicode 4-letter abbreviations for script names are now
recognized.
(e) In accordance with Unicode and Perl's "loose matching" rules, spaces,
hyphens, and underscores are ignored in property names, which are then
matched independent of case.
18. The Python scripts in the maint directory have been refactored. There are
now three scripts that generate pcre2_ucd.c, pcre2_ucp.h, and pcre2_ucptables.c
(which is #included by pcre2_tables.c). The data lists that used to be
duplicated are now held in a single common Python module.
19. On CHERI, and thus Arm's Morello prototype, pointers are represented as
hardware capabilities, which consist of both an integer address and additional
metadata, meaning they are twice the size of the platform's size_t type, i.e.
16 bytes on a 64-bit system. The ovector member of heapframe happens to only be
8 byte aligned, and so computing frame_size ended up with a multiple of 8 but
not 16. Whilst the first frame was always suitably aligned, this then
misaligned the frame that follows, resulting in an alignment fault when storing
a pointer to Fecode at the start of match. Patch to fix this issue by Jessica
Clarke PR#72.
20. Added -LP and -LS listing options to pcre2test.
21. A user discovered that the library names in CMakeLists.txt for MSVC
debugger (PDB) files were incorrect - perhaps never tried for PCRE2?
22. An item such as [Aa] is optimized into a caseless single character match.
When this was quantified (e.g. [Aa]{2}) and was also the last literal item in a
pattern, the optimizing "must be present for a match" character check was not
being flagged as caseless, causing some matches that should have succeeded to
fail.
23. Fixed a unicode property matching issue in JIT. The character was not
fully read in caseless matching.
24. Fixed an issue affecting recursions in JIT caused by duplicated data
transfers.
25. Merged patch from @carenas (GitHub #96) which fixes some problems with
pcre2test and readline/readedit:
* Use the right header for libedit in FreeBSD with autoconf
* Really allow libedit with cmake
* Avoid using readline headers with libedit
Version 10.39 29-October-2021
-----------------------------
1. Fix incorrect detection of alternatives in first character search in JIT.
2. Merged patch from @carenas (GitHub #28):
Visual Studio 2013 includes support for %zu and %td, so let newer
versions of it avoid the fallback, and while at it, make sure that
the first check is for DISABLE_PERCENT_ZT so it will be always
honoured if chosen.
prtdiff_t is signed, so use a signed type instead, and make sure
that an appropriate width is chosen if pointers are 64bit wide and
long is not (ex: Windows 64bit).
IMHO removing the cast (and therefore the possibility of truncation)
make the code cleaner and the fallback is likely portable enough
with all 64-bit POSIX systems doing LP64 except for Windows.
3. Merged patch from @carenas (GitHub #29) to update to Unicode 14.0.0.
4. Merged patch from @carenas (GitHub #30):
* Cleanup: remove references to no longer used stdint.h
Since 19c50b9d (Unconditionally use inttypes.h instead of trying for stdint.h
(simplification) and remove the now unnecessary inclusion in
pcre2_internal.h., 2018-11-14), stdint.h is no longer used.
Remove checks for it in autotools and CMake and document better the expected
build failures for systems that might have stdint.h (C99) and not inttypes.h
(from POSIX), like old Windows.
* Cleanup: remove detection for inttypes.h which is a hard dependency
CMake checks for standard headers are not meant to be used for hard
dependencies, so will prevent a possible fallback to work.
Alternatively, the header could be checked to make the configuration fail
instead of breaking the build, but that was punted, as it was missing anyway
from autotools.
5. Merged patch from @carenas (GitHub #32):
* jit: allow building with ancient MSVC versions
Visual Studio older than 2013 fails to build with JIT enabled, because it is
unable to parse non C89 compatible syntax, with mixed declarations and code.
While most recent compilers wouldn't even report this as a warning since it
is valid C99, it could be also made visible by adding to gcc/clang the
-Wdeclaration-after-statement flag at build time.
Move the code below the affected definitions.
* pcre2grep: avoid mixing declarations with code
Since d5a61ee8 (Patch to detect (and ignore) symlink loops in pcre2grep,
2021-08-28), code will fail to build in a strict C89 compiler.
Reformat slightly to make it C89 compatible again.
Version 10.38 01-October-2021
-----------------------------
1. Fix invalid single character repetition issues in JIT when the repetition
is inside a capturing bracket and the bracket is preceded by character
literals.
2. Installed revised CMake configuration files provided by Jan-Willem Blokland.
This extends the CMake build system to build both static and shared libraries
in one go, builds the static library with PIC, and exposes PCRE2 libraries
using the CMake config files. JWB provided these notes:
- Introduced CMake variable BUILD_STATIC_LIBS to build the static library.
- Make a small modification to config-cmake.h.in by removing the PCRE2_STATIC
variable. Added PCRE2_STATIC variable to the static build using the
target_compile_definitions() function.
- Extended the CMake config files.
- Introduced CMake variable PCRE2_USE_STATIC_LIBS to easily switch between
the static and shared libraries.
- Added the PCRE_STATIC variable to the target compile definitions for the
import of the static library.
Building static and shared libraries using MSVC results in a name clash of
the libraries. Both static and shared library builds create, for example, the
file pcre2-8.lib. Therefore, I decided to change the static library names by
adding "-static". For example, pcre2-8.lib has become pcre2-8-static.lib.
[Comment by PH: this is MSVC-specific. It doesn't happen on Linux.]
3. Increased the minimum release number for CMake to 3.0.0 because older than
2.8.12 is deprecated (it was set to 2.8.5) and causes warnings. Even 3.0.0 is
quite old; it was released in 2014.
4. Implemented a modified version of Thomas Tempelmann's pcre2grep patch for
detecting symlink loops. This is dependent on the availability of realpath(),
which is now tested for in ./configure and CMakeLists.txt.
5. Implemented a modified version of Thomas Tempelmann's patch for faster
case-independent "first code unit" searches for unanchored patterns in 8-bit
mode in the interpreters. Instead of just remembering whether one case matched
or not, it remembers the position of a previous match so as to avoid
unnecessary repeated searching.
6. Perl now locks out \K in lookarounds, so PCRE2 now does the same by default.
However, just in case anybody was relying on the old behaviour, there is an
option called PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK that enables the old behaviour.
An option has also been added to pcre2grep to enable this.
7. Re-enable a JIT optimization which was unintentionally disabled in 10.35.
8. There is a loop counter to catch excessively crazy patterns when checking
the lengths of lookbehinds at compile time. This was incorrectly getting reset
whenever a lookahead was processed, leading to some fuzzer-generated patterns
taking a very long time to compile when (?|) was present in the pattern,
because (?|) disables caching of group lengths.
Version 10.37 26-May-2021
-------------------------
1. Change RunGrepTest to use tr instead of sed when testing with binary
zero bytes, because sed varies a lot from system to system and has problems
with binary zeros. This is from Bugzilla #2681. Patch from Jeremie
Courreges-Anglas via Nam Nguyen. This fixes RunGrepTest for OpenBSD. Later:
it broke it for at least one version of Solaris, where tr can't handle binary
zeros. However, that system had /usr/xpg4/bin/tr installed, which works OK, so
RunGrepTest now checks for that command and uses it if found.
2. Compiling with gcc 10.2's -fanalyzer option showed up a hypothetical problem
with a NULL dereference. I don't think this case could ever occur in practice,
but I have put in a check in order to get rid of the compiler error.
3. An alternative patch for CMakeLists.txt because 10.36 #4 breaks CMake on
Windows. Patch from email@cs-ware.de fixes bugzilla #2688.
4. Two bugs related to over-large numbers have been fixed so the behaviour is
now the same as Perl.
(a) A pattern such as /\214748364/ gave an overflow error instead of being
treated as the octal number \214 followed by literal digits.
(b) A sequence such as {65536 that has no terminating } so is not a
quantifier was nevertheless complaining that a quantifier number was too big.
5. A run of autoconf suggested that configure.ac was out-of-date with respect
to the latest autoconf. Running autoupdate made some valid changes, some valid
suggestions, and also some invalid changes, which were fixed by hand. Autoconf
now runs clean and the resulting "configure" seems to work, so I hope nothing
is broken. Later: the requirement for autoconf 2.70 broke some automatic test
robots. It doesn't seem to be necessary: trying a reduction to 2.60.
6. The pattern /a\K.(?0)*/ when matched against "abac" by the interpreter gave
the answer "bac", whereas Perl and JIT both yield "c". This was because the
effect of \K was not propagating back from the full pattern recursion. Other
recursions such as /(a\K.(?1)*)/ did not have this problem.
7. Restore single character repetition optimization in JIT. Currently fewer
character repetitions are optimized than in 10.34.
8. When the names of the functions in the POSIX wrapper were changed to
pcre2_regcomp() etc. (see change 10.33 #4 below), functions with the original
names were left in the library so that pre-compiled programs would still work.
However, this has proved troublesome when programs link with several libraries,
some of which use PCRE2 via the POSIX interface while others use a native POSIX
library. For this reason, the POSIX function names are removed in this release.
The macros in pcre2posix.h should ensure that re-compiling fixes any programs
that haven't been compiled since before 10.33.
Version 10.36 04-December-2020
------------------------------
1. Add CET_CFLAGS so that when Intel CET is enabled, pass -mshstk to
compiler. This fixes https://bugs.exim.org/show_bug.cgi?id=2578. Patch for
Makefile.am and configure.ac by H.J. Lu. Equivalent patch for CMakeLists.txt
invented by PH.
2. Fix infinite loop when a single byte newline is searched in JIT when
invalid utf8 mode is enabled.
3. Updated CMakeLists.txt with patch from Wolfgang Stöggl (Bugzilla #2584):
- Include GNUInstallDirs and use ${CMAKE_INSTALL_LIBDIR} instead of hardcoded
lib. This allows differentiation between lib and lib64.
CMAKE_INSTALL_LIBDIR is used for installation of libraries and also for
pkgconfig file generation.
- Add the version of PCRE2 to the configuration summary like ./configure
does.
- Fix typo: MACTHED_STRING->MATCHED_STRING
4. Updated CMakeLists.txt with another patch from Wolfgang Stöggl (Bugzilla
#2588):
- Add escaped double quotes around include directory in CMakeLists.txt to
allow spaces in directory names.
- This fixes a cmake error, if the path of the pcre2 source contains a space.
5. Updated CMakeLists.txt with a patch from B. Scott Michel: CMake's
documentation suggests using CHECK_SYMBOL_EXISTS over CHECK_FUNCTION_EXIST.
Moreover, these functions come from specific header files, which need to be
specified (and, thankfully, are the same on both the Linux and WinXX
platforms.)
6. Added a (uint32_t) cast to prevent a compiler warning in pcre2_compile.c.
7. Applied a patch from Wolfgang Stöggl (Bugzilla #2600) to fix postfix for
debug Windows builds using CMake. This also updated configure so that it
generates *.pc files and pcre2-config with the same content, as in the past.
8. If a pattern ended with (?(VERSION=n.d where n is any number but d is just a
single digit, the code unit beyond d was being read (i.e. there was a read
buffer overflow). Fixes ClusterFuzz 23779.
9. After the rework in r1235, certain character ranges were incorrectly
handled by an optimization in JIT. Furthermore a wrong offset was used to
read a value from a buffer which could lead to memory overread.
10. Unnoticed for many years was the fact that delimiters other than / in the
testinput1 and testinput4 files could cause incorrect behaviour when these
files were processed by perltest.sh. There were several tests that used quotes
as delimiters, and it was just luck that they didn't go wrong with perltest.sh.
All the patterns in testinput1 and testinput4 now use / as their delimiter.
This fixes Bugzilla #2641.
11. Perl has started to give an error for \K within lookarounds (though there
are cases where it doesn't). PCRE2 still allows this, so the tests that include
this case have been moved from test 1 to test 2.
12. Further to 10 above, pcre2test has been updated to detect and grumble if a
delimiter other than / is used after #perltest.
13. Fixed a bug with PCRE2_MATCH_INVALID_UTF in 8-bit mode when PCRE2_CASELESS
was set and PCRE2_NO_START_OPTIMIZE was not set. The optimization for finding
the start of a match was not resetting correctly after a failed match on the
first valid fragment of the subject, possibly causing incorrect "no match"
returns on subsequent fragments. For example, the pattern /A/ failed to match
the subject \xe5A. Fixes Bugzilla #2642.
14. Fixed a bug in character set matching when JIT is enabled and both unicode
scripts and unicode classes are present at the same time.
15. Added GNU grep's -m (aka --max-count) option to pcre2grep.
16. Refactored substitution processing in pcre2grep strings, both for the -O
option and when dealing with callouts. There is now a single function that
handles $ expansion in all cases (instead of multiple copies of almost
identical code). This means that the same escape sequences are available
everywhere, which was not previously the case. At the same time, the escape
sequences $x{...} and $o{...} have been introduced, to allow for characters
whose code points are greater than 255 in Unicode mode.
17. Applied the patch from Bugzilla #2628 to RunGrepTest. This does an explicit
test for a version of sed that can handle binary zero, instead of assuming that
any Linux version will work. Later: replaced $(...) by `...` because not all
shells recognize the former.
18. Fixed a word boundary check bug in JIT when partial matching is enabled.
19. Fix ARM64 compilation warning in JIT. Patch by Carlo.
20. A bug in the RunTest script meant that if the first part of test 2 failed,
the failure was not reported.
21. Test 2 was failing when run from a directory other than the source
directory. This failure was previously missed in RunTest because of 20 above.
Fixes added to both RunTest and RunTest.bat.
22. Patch to CMakeLists.txt from Daniel to fix problem with testing under
Windows.
Version 10.35 09-May-2020
---------------------------
1. Use PCRE2_MATCH_EMPTY flag to detect empty matches in JIT.
2. Fix ARMv5 JIT improper handling of labels right after a constant pool.
3. A JIT bug is fixed which allowed to read the fields of the compiled
pattern before its existence is checked.
4. Back in the PCRE1 day, capturing groups that contained recursive back
references to themselves were made atomic (version 8.01, change 18) because
after the end a repeated group, the captured substrings had their values from
the final repetition, not from an earlier repetition that might be the
destination of a backtrack. This feature was documented, and was carried over
into PCRE2. However, it has now been realized that the major refactoring that
was done for 10.30 has made this atomizing unnecessary, and it is confusing
when users are unaware of it, making some patterns appear not to be working as
expected. Capture values of recursive back references in repeated groups are
now correctly backtracked, so this unnecessary restriction has been removed.
5. Added PCRE2_SUBSTITUTE_LITERAL.
6. Avoid some VS compiler warnings.
7. Added PCRE2_SUBSTITUTE_MATCHED.
8. Added (?* and (?<* as synonyms for (*napla: and (*naplb: to match another
regex engine. The Perl regex folks are aware of this usage and have made a note
about it.
9. When an assertion is repeated, PCRE2 used to limit the maximum repetition to
1, believing that repeating an assertion is pointless. However, if a positive
assertion contains capturing groups, repetition can be useful. In any case, an
assertion could always be wrapped in a repeated group. The only restriction
that is now imposed is that an unlimited maximum is changed to one more than
the minimum.
10. Fix *THEN verbs in lookahead assertions in JIT.
11. Added PCRE2_SUBSTITUTE_REPLACEMENT_ONLY.
12. The JIT stack should be freed when the low-level stack allocation fails.
13. In pcre2grep, if the final line in a scanned file is output but does not
end with a newline sequence, add a newline according to the --newline setting.
14. (?(DEFINE)...) groups were not being handled correctly when checking for
the fixed length of a lookbehind assertion. Such a group within a lookbehind
should be skipped, as it does not contribute to the length of the group.
Instead, the (DEFINE) group was being processed, and if at the end of the
lookbehind, that end was not correctly recognized. Errors such as "lookbehind
assertion is not fixed length" and also "internal error: bad code value in
parsed_skip()" could result.
15. Put a limit of 1000 on recursive calls in pcre2_study() when searching
nested groups for starting code units, in order to avoid stack overflow issues.
If the limit is reached, it just gives up trying for this optimization.
16. The control verb chain list must always be restored when exiting from a
recurse function in JIT.
17. Fix a crash which occurs when the character type of an invalid UTF
character is decoded in JIT.
18. Changes in many areas of the code so that when Unicode is supported and
PCRE2_UCP is set without PCRE2_UTF, Unicode character properties are used for
upper/lower case computations on characters whose code points are greater than
127.
19. The function for checking UTF-16 validity was returning an incorrect offset
for the start of the error when a high surrogate was not followed by a valid
low surrogate. This caused incorrect behaviour, for example when
PCRE2_MATCH_INVALID_UTF was set and a match started immediately following the
invalid high surrogate, such as /aa/ matching "\x{d800}aa".
20. If a DEFINE group immediately preceded a lookbehind assertion, the pattern
could be mis-compiled and therefore not match correctly. This is the example
that found this: /(?(DEFINE)(?<foo>bar))(?<![-a-z0-9])word/ which failed to
match "word" because the "move back" value was set to zero.
21. Following a request from a user, some extensions and tidies to the
character tables handling have been done:
(a) The dftables auxiliary program is renamed pcre2_dftables, but it is still
not installed for public use.
(b) There is now a -b option for pcre2_dftables, which causes the tables to
be written in binary. There is also a -help option.
(c) PCRE2_CONFIG_TABLES_LENGTH is added to pcre2_config() so that an
application that wants to save tables in binary knows how long they are.
22. Changed setting of CMAKE_MODULE_PATH in CMakeLists.txt from SET to
LIST(APPEND...) to allow a setting from the command line to be included.
23. Updated to Unicode 13.0.0.
24. CMake build now checks for secure_getenv() and strerror(). Patch by Carlo.
25. Avoid using [-1] as a suffix in pcre2test because it can provoke a compiler
warning.
26. Added tests for __attribute__((uninitialized)) to both the configure and
CMake build files, and then applied this attribute to the variable called
stack_frames_vector[] in pcre2_match(). When implemented, this disables
automatic initialization (a facility in clang), which can take time on big
variables.
27. Updated CMakeLists.txt (patches by Uwe Korn) to add support for
pcre2-config, the libpcre*.pc files, SOVERSION, VERSION and the
MACHO_*_VERSIONS settings for CMake builds.
28. Another patch to CMakeLists.txt to check for mkostemp (configure already
does). Patch by Carlo Marcelo Arenas Belon.
29. Check for the existence of memfd_create in both CMake and configure
configurations. Patch by Carlo Marcelo Arenas Belon.
30. Restrict the configuration setting for the SELinux compatible execmem
allocator (change 10.30/44) to Linux and NetBSD.
Version 10.34 21-November-2019
------------------------------
1. The maximum number of capturing subpatterns is 65535 (documented), but no
check on this was ever implemented. This omission has been rectified; it fixes
ClusterFuzz 14376.
2. Improved the invalid utf32 support of the JIT compiler. Now it correctly
detects invalid characters in the 0xd800-0xdfff range.
3. Fix minor typo bug in JIT compile when \X is used in a non-UTF string.
4. Add support for matching in invalid UTF strings to the pcre2_match()
interpreter, and integrate with the existing JIT support via the new
PCRE2_MATCH_INVALID_UTF compile-time option.
5. Give more error detail for invalid UTF-8 when detected in pcre2grep.
6. Add support for invalid UTF-8 to pcre2grep.
7. Adjust the limit for "must have" code unit searching, in particular,
increase it substantially for non-anchored patterns.
8. Allow (*ACCEPT) to be quantified, because an ungreedy quantifier with a zero
minimum is potentially useful.
9. Some changes to the way the minimum subject length is handled:
* When PCRE2_NO_START_OPTIMIZE is set, no minimum length is computed;
pcre2test now omits this item instead of showing a value of zero.
* An incorrect minimum length could be calculated for a pattern that
contained (*ACCEPT) inside a qualified group whose minimum repetition was
zero, for example /A(?:(*ACCEPT))?B/, which incorrectly computed a minimum
of 2. The minimum length scan no longer happens for a pattern that
contains (*ACCEPT).
* When no minimum length is set by the normal scan, but a first and/or last
code unit is recorded, set the minimum to 1 or 2 as appropriate.
* When a pattern contains multiple groups with the same number, a back
reference cannot know which one to scan for a minimum length. This used to
cause the minimum length finder to give up with no result. Now it treats
such references as not adding to the minimum length (which it should have
done all along).
* Furthermore, the above action now happens only if the back reference is to
a group that exists more than once in a pattern instead of any back
reference in a pattern with duplicate numbers.
10. A (*MARK) value inside a successful condition was not being returned by the
interpretive matcher (it was returned by JIT). This bug has been mended.
11. A bug in pcre2grep meant that -o without an argument (or -o0) didn't work
if the pattern had more than 32 capturing parentheses. This is fixed. In
addition (a) the default limit for groups requested by -o<n> has been raised to
50, (b) the new --om-capture option changes the limit, (c) an error is raised
if -o asks for a group that is above the limit.
12. The quantifier {1} was always being ignored, but this is incorrect when it
is made possessive and applied to an item in parentheses, because a
parenthesized item may contain multiple branches or other backtracking points,
for example /(a|ab){1}+c/ or /(a+){1}+a/.
13. For partial matches, pcre2test was always showing the maximum lookbehind
characters, flagged with "<", which is misleading when the lookbehind didn't
actually look behind the start (because it was later in the pattern). Showing
all consulted preceding characters for partial matches is now controlled by the
existing "allusedtext" modifier and, as for complete matches, this facility is
available only for non-JIT matching, because JIT does not maintain the first
and last consulted characters.
14. DFA matching (using pcre2_dfa_match()) was not recognising a partial match
if the end of the subject was encountered in a lookahead (conditional or
otherwise), an atomic group, or a recursion.
15. Give error if pcre2test -t, -T, -tm or -TM is given an argument of zero.
16. Check for integer overflow when computing lookbehind lengths. Fixes
Clusterfuzz issue 15636.
17. Implemented non-atomic positive lookaround assertions.
18. If a lookbehind contained a lookahead that contained another lookbehind
within it, the nested lookbehind was not correctly processed. For example, if
/(?<=(?=(?<=a)))b/ was matched to "ab" it gave no match instead of matching
"b".
19. Implemented pcre2_get_match_data_size().
20. Two alterations to partial matching:
(a) The definition of a partial match is slightly changed: if a pattern
contains any lookbehinds, an empty partial match may be given, because this
is another situation where adding characters to the current subject can
lead to a full match. Example: /c*+(?<=[bc])/ with subject "ab".
(b) Similarly, if a pattern could match an empty string, an empty partial
match may be given. Example: /(?![ab]).*/ with subject "ab". This case
applies only to PCRE2_PARTIAL_HARD.
(c) An empty string partial hard match can be returned for \z and \Z as it
is documented that they shouldn't match.
21. A branch that started with (*ACCEPT) was not being recognized as one that
could match an empty string.
22. Corrected pcre2_set_character_tables() tables data type: was const unsigned
char * instead of const uint8_t *, as generated by pcre2_maketables().
23. Upgraded to Unicode 12.1.0.
24. Add -jitfast command line option to pcre2test (to make all the jit options
available directly).
25. Make pcre2test -C show if libreadline or libedit is supported.
26. If the length of one branch of a group exceeded 65535 (the maximum value
that is remembered as a minimum length), the whole group's length was
incorrectly recorded as 65535, leading to incorrect "no match" when start-up
optimizations were in force.
27. The "rightmost consulted character" value was not always correct; in
particular, if a pattern ended with a negative lookahead, characters that were
inspected in that lookahead were not included.
28. Add the pcre2_maketables_free() function.
29. The start-up optimization that looks for a unique initial matching
code unit in the interpretive engines uses memchr() in 8-bit mode. When the
search is caseless, it was doing so inefficiently, which ended up slowing down
the match drastically when the subject was very long. The revised code (a)
remembers if one case is not found, so it never repeats the search for that
case after a bumpalong and (b) when one case has been found, it searches only
up to that position for an earlier occurrence of the other case. This fix
applies to both interpretive pcre2_match() and to pcre2_dfa_match().
30. While scanning to find the minimum length of a group, if any branch has
minimum length zero, there is no need to scan any subsequent branches (a small
compile-time performance improvement).
31. Installed a .gitignore file on a user's suggestion. When using the svn
repository with git (through git svn) this helps keep it tidy.
32. Add underflow check in JIT which may occur when the value of subject
string pointer is close to 0.
33. Arrange for classes such as [Aa] which contain just the two cases of the
same character, to be treated as a single caseless character. This causes the
first and required code unit optimizations to kick in where relevant.
34. Improve the bitmap of starting bytes for positive classes that include wide
characters, but no property types, in UTF-8 mode. Previously, on encountering
such a class, the bits for all bytes greater than \xc4 were set, thus
specifying any character with codepoint >= 0x100. Now the only bits that are
set are for the relevant bytes that start the wide characters. This can give a
noticeable performance improvement.
35. If the bitmap of starting code units contains only 1 or 2 bits, replace it
with a single starting code unit (1 bit) or a caseless single starting code
unit if the two relevant characters are case-partners. This is particularly
relevant to the 8-bit library, though it applies to all. It can give a
performance boost for patterns such as [Ww]ord and (word|WORD). However, this
optimization doesn't happen if there is a "required" code unit of the same
value (because the search for a "required" code unit starts at the match start
for non-unique first code unit patterns, but after a unique first code unit,
and patterns such as a*a need the former action).
36. Small patch to pcre2posix.c to set the erroroffset field to -1 immediately
after a successful compile, instead of at the start of matching to avoid a
sanitizer complaint (regexec is supposed to be thread safe).
37. Add NEON vectorization to JIT to speed up matching of first character and
pairs of characters on ARM64 CPUs.
38. If a non-ASCII character was the first in a starting assertion in a
caseless match, the "first code unit" optimization did not get the casing
right, and the assertion failed to match a character in the other case if it
did not start with the same code unit.
39. Fixed the incorrect computation of jump sizes on x86 CPUs in JIT. A masking
operation was incorrectly removed in r1136. Reported by Ralf Junker.
Version 10.33 16-April-2019
---------------------------
1. Added "allvector" to pcre2test to make it easy to check the part of the
ovector that shouldn't be changed, in particular after substitute and failed or
partial matches.
2. Fix subject buffer overread in JIT when UTF is disabled and \X or \R has
a greater than 1 fixed quantifier. This issue was found by Yunho Kim.
3. Added support for callouts from pcre2_substitute(). After 10.33-RC1, but
prior to release, fixed a bug that caused a crash if pcre2_substitute() was
called with a NULL match context.
4. The POSIX functions are now all called pcre2_regcomp() etc., with wrapper
functions that use the standard POSIX names. However, in pcre2posix.h the POSIX
names are defined as macros. This should help avoid linking with the wrong
library in some environments while still exporting the POSIX names for
pre-existing programs that use them. (The Debian alternative names are also
defined as macros, but not documented.)
5. Fix an xclass matching issue in JIT.
6. Implement PCRE2_EXTRA_ESCAPED_CR_IS_LF (see Bugzilla 2315).
7. Implement the Perl 5.28 experimental alphabetic names for atomic groups and
lookaround assertions, for example, (*pla:...) and (*atomic:...). These are
characterized by a lower case letter following (* and to simplify coding for
this, the character tables created by pcre2_maketables() were updated to add a
new "is lower case letter" bit. At the same time, the now unused "is
hexadecimal digit" bit was removed. The default tables in
src/pcre2_chartables.c.dist are updated.
8. Implement the new Perl "script run" features (*script_run:...) and
(*atomic_script_run:...) aka (*sr:...) and (*asr:...).
9. Fixed two typos in change 22 for 10.21, which added special handling for
ranges such as a-z in EBCDIC environments. The original code probably never
worked, though there were no bug reports.
10. Implement PCRE2_COPY_MATCHED_SUBJECT for pcre2_match() (including JIT via
pcre2_match()) and pcre2_dfa_match(), but *not* the pcre2_jit_match() fast
path. Also, when a match fails, set the subject field in the match data to NULL
for tidiness - none of the substring extractors should reference this after
match failure.
11. If a pattern started with a subroutine call that had a quantifier with a
minimum of zero, an incorrect "match must start with this character" could be
recorded. Example: /(?&xxx)*ABC(?<xxx>XYZ)/ would (incorrectly) expect 'A' to
be the first character of a match.
12. The heap limit checking code in pcre2_dfa_match() could suffer from
overflow if the heap limit was set very large. This could cause incorrect "heap
limit exceeded" errors.
13. Add "kibibytes" to the heap limit output from pcre2test -C to make the
units clear.
14. Add a call to pcre2_jit_free_unused_memory() in pcre2grep, for tidiness.
15. Updated the VMS-specific code in pcre2test on the advice of a VMS user.
16. Removed the unnecessary inclusion of stdint.h (or inttypes.h) from
pcre2_internal.h as it is now included by pcre2.h. Also, change 17 for 10.32
below was unnecessarily complicated, as inttypes.h is a Standard C header,
which is defined to be a superset of stdint.h. Instead of conditionally
including stdint.h or inttypes.h, pcre2.h now unconditionally includes
inttypes.h. This supports environments that do not have stdint.h but do have
inttypes.h, which are known to exist. A note in the autotools documentation
says (November 2018) that there are none known that are the other way round.
17. Added --disable-percent-zt to "configure" (and equivalent to CMake) to
forcibly disable the use of %zu and %td in formatting strings because there is
at least one version of VMS that claims to be C99 but does not support these
modifiers.
18. Added --disable-pcre2grep-callout-fork, which restricts the callout support
in pcre2grep to the inbuilt echo facility. This may be useful in environments
that do not support fork().
19. Fix two instances of <= 0 being applied to unsigned integers (the VMS
compiler complains).
20. Added "fork" support for VMS to pcre2grep, for running an external program
via a string callout.
21. Improve MAP_JIT flag usage on MacOS. Patch by Rich Siegel.
22. If a pattern started with (*MARK), (*COMMIT), (*PRUNE), (*SKIP), or (*THEN)
followed by ^ it was not recognized as anchored.
23. The RunGrepTest script used to cut out the test of NUL characters for
Solaris and MacOS as printf and sed can't handle them. It seems that the *BSD
systems can't either. I've inverted the test so that only those OS that are
known to work (currently only Linux) try to run this test.
24. Some tests in RunGrepTest appended to testtrygrep from two different file
descriptors instead of redirecting stderr to stdout. This worked on Linux, but
it was reported not to on other systems, causing the tests to fail.
25. In the RunTest script, make the test for stack setting use the same value
for the stack as it needs for -bigstack.
26. Insert a cast in pcre2_dfa_match.c to suppress a compiler warning.
26. With PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL set, escape sequences such as \s
which are valid in character classes, but not as the end of ranges, were being
treated as literals. An example is [_-\s] (but not [\s-_] because that gave an
error at the *start* of a range). Now an "invalid range" error is given
independently of PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL.
27. Related to 26 above, PCRE2_BAD_ESCAPE_IS_LITERAL was affecting known escape
sequences such as \eX when they appeared invalidly in a character class. Now
the option applies only to unrecognized or malformed escape sequences.
28. Fix word boundary in JIT compiler. Patch by Mike Munday.
29. The pcre2_dfa_match() function was incorrectly handling conditional version
tests such as (?(VERSION>=0)...) when the version test was true. Incorrect
processing or a crash could result.
30. When PCRE2_UTF is set, allow non-ASCII letters and decimal digits in group
names, as Perl does. There was a small bug in this new code, found by
ClusterFuzz 12950, fixed before release.
31. Implemented PCRE2_EXTRA_ALT_BSUX to support ECMAScript 6's \u{hhh}
construct.
32. Compile \p{Any} to be the same as . in DOTALL mode, so that it benefits
from auto-anchoring if \p{Any}* starts a pattern.
33. Compile invalid UTF check in JIT test when only pcre32 is enabled.
34. For some time now, CMake has been warning about the setting of policy
CMP0026 to "OLD" in CmakeLists.txt, and hinting that the feature might be
removed in a future version. A request for CMake expertise on the list produced
no result, so I have now hacked CMakeLists.txt along the lines of some changes
I found on the Internet. The new code no longer needs the policy setting, and
it appears to work fine on Linux.
35. Setting --enable-jit=auto for an out-of-tree build failed because the
source directory wasn't in the search path for AC_TRY_COMPILE always. Patch
from Ross Burton.
36. Disable SSE2 JIT optimizations in x86 CPUs when SSE2 is not available.
Patch by Guillem Jover.
37. Changed expressions such as 1<<10 to 1u<<10 in many places because compiler
warnings were reported.
38. Using the clang compiler with sanitizing options causes runtime complaints
about truncation for statements such as x = ~x when x is an 8-bit value; it
seems to compute ~x as a 32-bit value. Changing such statements to x = 255 ^ x
gets rid of the warnings. There were also two missing casts in pcre2test.
Version 10.32 10-September-2018
-------------------------------
1. When matching using the REG_STARTEND feature of the POSIX API with a
non-zero starting offset, unset capturing groups with lower numbers than a
group that did capture something were not being correctly returned as "unset"
(that is, with offset values of -1).
2. When matching using the POSIX API, pcre2test used to omit listing unset
groups altogether. Now it shows those that come before any actual captures as
"<unset>", as happens for non-POSIX matching.
3. Running "pcre2test -C" always stated "\R matches CR, LF, or CRLF only",
whatever the build configuration was. It now correctly says "\R matches all
Unicode newlines" in the default case when --enable-bsr-anycrlf has not been
specified. Similarly, running "pcre2test -C bsr" never produced the result
ANY.
4. Matching the pattern /(*UTF)\C[^\v]+\x80/ against an 8-bit string containing
multi-code-unit characters caused bad behaviour and possibly a crash. This
issue was fixed for other kinds of repeat in release 10.20 by change 19, but
repeating character classes were overlooked.
5. pcre2grep now supports the inclusion of binary zeros in patterns that are
read from files via the -f option.
6. A small fix to pcre2grep to avoid compiler warnings for -Wformat-overflow=2.
7. Added --enable-jit=auto support to configure.ac.
8. Added some dummy variables to the heapframe structure in 16-bit and 32-bit
modes for the benefit of m68k, where pointers can be 16-bit aligned. The
dummies force 32-bit alignment and this ensures that the structure is a
multiple of PCRE2_SIZE, a requirement that is tested at compile time. In other
architectures, alignment requirements take care of this automatically.
9. When returning an error from pcre2_pattern_convert(), ensure the error
offset is set zero for early errors.
10. A number of patches for Windows support from Daniel Richard G:
(a) List of error numbers in Runtest.bat corrected (it was not the same as in
Runtest).
(b) pcre2grep snprintf() workaround as used elsewhere in the tree.
(c) Support for non-C99 snprintf() that returns -1 in the overflow case.
11. Minor tidy of pcre2_dfa_match() code.
12. Refactored pcre2_dfa_match() so that the internal recursive calls no longer
use the stack for local workspace and local ovectors. Instead, an initial block
of stack is reserved, but if this is insufficient, heap memory is used. The
heap limit parameter now applies to pcre2_dfa_match().
13. If a "find limits" test of DFA matching in pcre2test resulted in too many
matches for the ovector, no matches were displayed.
14. Removed an occurrence of ctrl/Z from test 6 because Windows treats it as
EOF. The test looks to have come from a fuzzer.
15. If PCRE2 was built with a default match limit a lot greater than the
default default of 10 000 000, some JIT tests of the match limit no longer
failed. All such tests now set 10 000 000 as the upper limit.
16. Another Windows related patch for pcregrep to ensure that WIN32 is
undefined under Cygwin.
17. Test for the presence of stdint.h and inttypes.h in configure and CMake and
include whichever exists (stdint preferred) instead of unconditionally
including stdint. This makes life easier for old and non-standard systems.
18. Further changes to improve portability, especially to old and or non-
standard systems:
(a) Put all printf arguments in RunGrepTest into single, not double, quotes,
and use \0 not \x00 for binary zero.
(b) Avoid the use of C++ (i.e. BCPL) // comments.
(c) Parameterize the use of %zu in pcre2test to make it like %td. For both of
these now, if using MSVC or a standard C before C99, %lu is used with a
cast if necessary.
19. Applied a contributed patch to CMakeLists.txt to increase the stack size
when linking pcre2test with MSVC. This gets rid of a stack overflow error in
the standard set of tests.
20. Output a warning in pcre2test when ignoring the "altglobal" modifier when
it is given with the "replace" modifier.
21. In both pcre2test and pcre2_substitute(), with global matching, a pattern
that matched an empty string, but never at the starting match offset, was not
handled in a Perl-compatible way. The pattern /(<?=\G.)/ is an example of such
a pattern. Because \G is in a lookbehind assertion, there has to be a
"bumpalong" before there can be a match. The automatic "advance by one
character after an empty string match" rule is therefore inappropriate. A more
complicated algorithm has now been implemented.
22. When checking to see if a lookbehind is of fixed length, lookaheads were
correctly ignored, but qualifiers on lookaheads were not being ignored, leading
to an incorrect "lookbehind assertion is not fixed length" error.
23. The VERSION condition test was reading fractional PCRE2 version numbers
such as the 04 in 10.04 incorrectly and hence giving wrong results.
24. Updated to Unicode version 11.0.0. As well as the usual addition of new
scripts and characters, this involved re-jigging the grapheme break property
algorithm because Unicode has changed the way emojis are handled.
25. Fixed an obscure bug that struck when there were two atomic groups not
separated by something with a backtracking point. There could be an incorrect
backtrack into the first of the atomic groups. A complicated example is
/(?>a(*:1))(?>b)(*SKIP:1)x|.*/ matched against "abc", where the *SKIP
shouldn't find a MARK (because is in an atomic group), but it did.
26. Upgraded the perltest.sh script: (1) #pattern lines can now be used to set
a list of modifiers for all subsequent patterns - only those that the script
recognizes are meaningful; (2) #subject lines can be used to set or unset a
default "mark" modifier; (3) Unsupported #command lines give a warning when
they are ignored; (4) Mark data is output only if the "mark" modifier is
present.
27. (*ACCEPT:ARG), (*FAIL:ARG), and (*COMMIT:ARG) are now supported.
28. A (*MARK) name was not being passed back for positive assertions that were
terminated by (*ACCEPT).
29. Add support for \N{U+dddd}, but only in Unicode mode.
30. Add support for (?^) for unsetting all imnsx options.
31. The PCRE2_EXTENDED (/x) option only ever discarded space characters whose
code point was less than 256 and that were recognized by the lookup table
generated by pcre2_maketables(), which uses isspace() to identify white space.
Now, when Unicode support is compiled, PCRE2_EXTENDED also discards U+0085,
U+200E, U+200F, U+2028, and U+2029, which are additional characters defined by
Unicode as "Pattern White Space". This makes PCRE2 compatible with Perl.
32. In certain circumstances, option settings within patterns were not being
correctly processed. For example, the pattern /((?i)A)(?m)B/ incorrectly
matched "ab". (The (?m) setting lost the fact that (?i) should be reset at the
end of its group during the parse process, but without another setting such as
(?m) the compile phase got it right.) This bug was introduced by the
refactoring in release 10.23.
33. PCRE2 uses bcopy() if available when memmove() is not, and it used just to
define memmove() as function call to bcopy(). This hasn't been tested for a
long time because in pcre2test the result of memmove() was being used, whereas
bcopy() doesn't return a result. This feature is now refactored always to call
an emulation function when there is no memmove(). The emulation makes use of
bcopy() when available.
34. When serializing a pattern, set the memctl, executable_jit, and tables
fields (that is, all the fields that contain pointers) to zeros so that the
result of serializing is always the same. These fields are re-set when the
pattern is deserialized.
35. In a pattern such as /[^\x{100}-\x{ffff}]*[\x80-\xff]/ which has a repeated
negative class with no characters less than 0x100 followed by a positive class
with only characters less than 0x100, the first class was incorrectly being
auto-possessified, causing incorrect match failures.
36. Removed the character type bit ctype_meta, which dates from PCRE1 and is
not used in PCRE2.
37. Tidied up unnecessarily complicated macros used in the escapes table.
38. Since 10.21, the new testoutput8-16-4 file has accidentally been omitted
from distribution tarballs, owing to a typo in Makefile.am which had
testoutput8-16-3 twice. Now fixed.
39. If the only branch in a conditional subpattern was anchored, the whole
subpattern was treated as anchored, when it should not have been, since the
assumed empty second branch cannot be anchored. Demonstrated by test patterns
such as /(?(1)^())b/ or /(?(?=^))b/.
40. A repeated conditional subpattern that could match an empty string was
always assumed to be unanchored. Now it is checked just like any other
repeated conditional subpattern, and can be found to be anchored if the minimum
quantifier is one or more. I can't see much use for a repeated anchored
pattern, but the behaviour is now consistent.
41. Minor addition to pcre2_jit_compile.c to avoid static analyzer complaint
(for an event that could never occur but you had to have external information
to know that).
42. If before the first match in a file that was being searched by pcre2grep
there was a line that was sufficiently long to cause the input buffer to be
expanded, the variable holding the location of the end of the previous match
was being adjusted incorrectly, and could cause an overflow warning from a code
sanitizer. However, as the value is used only to print pending "after" lines
when the next match is reached (and there are no such lines in this case) this
bug could do no damage.
Version 10.31 12-February-2018
------------------------------
1. Fix typo (missing ]) in VMS code in pcre2test.c.
2. Replace the replicated code for matching extended Unicode grapheme sequences
(which got a lot more complicated by change 10.30/49) by a single subroutine
that is called by both pcre2_match() and pcre2_dfa_match().
3. Add idempotent guard to pcre2_internal.h.
4. Add new pcre2_config() options: PCRE2_CONFIG_NEVER_BACKSLASH_C and
PCRE2_CONFIG_COMPILED_WIDTHS.
5. Cut out \C tests in the JIT regression tests when NEVER_BACKSLASH_C is
defined (e.g. by --enable-never-backslash-C).
6. Defined public names for all the pcre2_compile() error numbers, and used
the public names in pcre2_convert.c.
7. Fixed a small memory leak in pcre2test (convert contexts).
8. Added two casts to compile.c and one to match.c to avoid compiler warnings.
9. Added code to pcre2grep when compiled under VMS to set the symbol
PCRE2GREP_RC to the exit status, because VMS does not distinguish between
exit(0) and exit(1).
10. Added the -LM (list modifiers) option to pcre2test. Also made -C complain
about a bad option only if the following argument item does not start with a
hyphen.
11. pcre2grep was truncating components of file names to 128 characters when
processing files with the -r option, and also (some very odd code) truncating
path names to 512 characters. There is now a check on the absolute length of
full path file names, which may be up to 2047 characters long.
12. When an assertion contained (*ACCEPT) it caused all open capturing groups
to be closed (as for a non-assertion ACCEPT), which was wrong and could lead to
misbehaviour for subsequent references to groups that started outside the
assertion. ACCEPT in an assertion now closes only those groups that were
started within that assertion. Fixes oss-fuzz issues 3852 and 3891.
13. Multiline matching in pcre2grep was misbehaving if the pattern matched
within a line, and then matched again at the end of the line and over into
subsequent lines. Behaviour was different with and without colouring, and
sometimes context lines were incorrectly printed and/or line endings were lost.
All these issues should now be fixed.
14. If --line-buffered was specified for pcre2grep when input was from a
compressed file (.gz or .bz2) a segfault occurred. (Line buffering should be
ignored for compressed files.)
15. Although pcre2_jit_match checks whether the pattern is compiled
in a given mode, it was also expected that at least one mode is available.
This is fixed and pcre2_jit_match returns with PCRE2_ERROR_JIT_BADOPTION
when the pattern is not optimized by JIT at all.
16. The line number and related variables such as match counts in pcre2grep
were all int variables, causing overflow when files with more than 2147483647
lines were processed (assuming 32-bit ints). They have all been changed to
unsigned long ints.
17. If a backreference with a minimum repeat count of zero was first in a
pattern, apart from assertions, an incorrect first matching character could be
recorded. For example, for the pattern /(?=(a))\1?b/, "b" was incorrectly set
as the first character of a match.
18. Characters in a leading positive assertion are considered for recording a
first character of a match when the rest of the pattern does not provide one.
However, a character in a non-assertive group within a leading assertion such
as in the pattern /(?=(a))\1?b/ caused this process to fail. This was an
infelicity rather than an outright bug, because it did not affect the result of
a match, just its speed. (In fact, in this case, the starting 'a' was
subsequently picked up in the study.)
19. A minor tidy in pcre2_match(): making all PCRE2_ERROR_ returns use "return"
instead of "RRETURN" saves unwinding the backtracks in these cases (only one
didn't).
20. Allocate a single callout block on the stack at the start of pcre2_match()
and set its never-changing fields once only. Do the same for pcre2_dfa_match().
21. Save the extra compile options (set in the compile context) with the
compiled pattern (they were not previously saved), add PCRE2_INFO_EXTRAOPTIONS
to retrieve them, and update pcre2test to show them.
22. Added PCRE2_CALLOUT_STARTMATCH and PCRE2_CALLOUT_BACKTRACK bits to a new
field callout_flags in callout blocks. The bits are set by pcre2_match(), but
not by JIT or pcre2_dfa_match(). Their settings are shown in pcre2test callouts
if the callout_extra subject modifier is set. These bits are provided to help
with tracking how a backtracking match is proceeding.
23. Updated the pcre2demo.c demonstration program, which was missing the extra
code for -g that handles the case when \K in an assertion causes the match to
end at the original start point. Also arranged for it to detect when \K causes
the end of a match to be before its start.
24. Similar to 23 above, strange things (including loops) could happen in
pcre2grep when \K was used in an assertion when --colour was used or in
multiline mode. The "end at original start point" bug is fixed, and if the end
point is found to be before the start point, they are swapped.
25. When PCRE2_FIRSTLINE without PCRE2_NO_START_OPTIMIZE was used in non-JIT
matching (both pcre2_match() and pcre2_dfa_match()) and the matched string
started with the first code unit of a newline sequence, matching failed because
it was not tried at the newline.
26. Code for giving up a non-partial match after failing to find a starting
code unit anywhere in the subject was missing when searching for one of a
number of code units (the bitmap case) in both pcre2_match() and
pcre2_dfa_match(). This was a missing optimization rather than a bug.
27. Tidied up the ACROSSCHAR macro to be like FORWARDCHAR and BACKCHAR, using a
pointer argument rather than a code unit value. This should not have affected
the generated code.
28. The JIT compiler has been updated.
29. Avoid pointer overflow for unset captures in pcre2_substring_list_get().
This could not actually cause a crash because it was always used in a memcpy()
call with zero length.
30. Some internal structures have a variable-length ovector[] as their last
element. Their actual memory is obtained dynamically, giving an ovector of
appropriate length. However, they are defined in the structure as
ovector[NUMBER], where NUMBER is large so that array bound checkers don't
grumble. The value of NUMBER was 10000, but a fuzzer exceeded 5000 capturing
groups, making the ovector larger than this. The number has been increased to
131072, which allows for the maximum number of captures (65535) plus the
overall match. This fixes oss-fuzz issue 5415.
31. Auto-possessification at the end of a capturing group was dependent on what
follows the group (e.g. /(a+)b/ would auto-possessify the a+) but this caused
incorrect behaviour when the group was called recursively from elsewhere in the
pattern where something different might follow. This bug is an unforseen
consequence of change #1 for 10.30 - the implementation of backtracking into
recursions. Iterators at the ends of capturing groups are no longer considered
for auto-possessification if the pattern contains any recursions. Fixes
Bugzilla #2232.
Version 10.30 14-August-2017
----------------------------
1. The main interpreter, pcre2_match(), has been refactored into a new version
that does not use recursive function calls (and therefore the stack) for
remembering backtracking positions. This makes --disable-stack-for-recursion a
NOOP. The new implementation allows backtracking into recursive group calls in
patterns, making it more compatible with Perl, and also fixes some other
hard-to-do issues such as #1887 in Bugzilla. The code is also cleaner because
the old code had a number of fudges to try to reduce stack usage. It seems to
run no slower than the old code.
A number of bugs in the refactored code were subsequently fixed during testing
before release, but after the code was made available in the repository. These
bugs were never in fully released code, but are noted here for the record.
(a) If a pattern had fewer capturing parentheses than the ovector supplied in
the match data block, a memory error (detectable by ASAN) occurred after
a match, because the external block was being set from non-existent
internal ovector fields. Fixes oss-fuzz issue 781.
(b) A pattern with very many capturing parentheses (when the internal frame
size was greater than the initial frame vector on the stack) caused a
crash. A vector on the heap is now set up at the start of matching if the
vector on the stack is not big enough to handle at least 10 frames.
Fixes oss-fuzz issue 783.
(c) Handling of (*VERB)s in recursions was wrong in some cases.
(d) Captures in negative assertions that were used as conditions were not
happening if the assertion matched via (*ACCEPT).
(e) Mark values were not being passed out of recursions.
(f) Refactor some code in do_callout() to avoid picky compiler warnings about
negative indices. Fixes oss-fuzz issue 1454.
(g) Similarly refactor the way the variable length ovector is addressed for
similar reasons. Fixes oss-fuzz issue 1465.
2. Now that pcre2_match() no longer uses recursive function calls (see above),
the "match limit recursion" value seems misnamed. It still exists, and limits
the depth of tree that is searched. To avoid future confusion, it has been
renamed as "depth limit" in all relevant places (--with-depth-limit,
(*LIMIT_DEPTH), pcre2_set_depth_limit(), etc) but the old names are still
available for backwards compatibility.
3. Hardened pcre2test so as to reduce the number of bugs reported by fuzzers:
(a) Check for malloc failures when getting memory for the ovector (POSIX) or
the match data block (non-POSIX).
4. In the 32-bit library in non-UTF mode, an attempt to find a Unicode property
for a character with a code point greater than 0x10ffff (the Unicode maximum)
caused a crash.
5. If a lookbehind assertion that contained a back reference to a group
appearing later in the pattern was compiled with the PCRE2_ANCHORED option,
undefined actions (often a segmentation fault) could occur, depending on what
other options were set. An example assertion is (?<!\1(abc)) where the
reference \1 precedes the group (abc). This fixes oss-fuzz issue 865.
6. Added the PCRE2_INFO_FRAMESIZE item to pcre2_pattern_info() and arranged for
pcre2test to use it to output the frame size when the "framesize" modifier is
given.
7. Reworked the recursive pattern matching in the JIT compiler to follow the
interpreter changes.
8. When the zero_terminate modifier was specified on a pcre2test subject line
for global matching, unpredictable things could happen. For example, in UTF-8
mode, the pattern //g,zero_terminate read random memory when matched against an
empty string with zero_terminate. This was a bug in pcre2test, not the library.
9. Moved some Windows-specific code in pcre2grep (introduced in 10.23/13) out
of the section that is compiled when Unix-style directory scanning is
available, and into a new section that is always compiled for Windows.
10. In pcre2test, explicitly close the file after an error during serialization
or deserialization (the "load" or "save" commands).
11. Fix memory leak in pcre2_serialize_decode() when the input is invalid.
12. Fix potential NULL dereference in pcre2_callout_enumerate() if called with
a NULL pattern pointer when Unicode support is available.
13. When the 32-bit library was being tested by pcre2test, error messages that
were longer than 64 code units could cause a buffer overflow. This was a bug in
pcre2test.
14. The alternative matching function, pcre2_dfa_match() misbehaved if it
encountered a character class with a possessive repeat, for example [a-f]{3}+.
15. The depth (formerly recursion) limit now applies to DFA matching (as
of 10.23/36); pcre2test has been upgraded so that \=find_limits works with DFA
matching to find the minimum value for this limit.
16. Since 10.21, if pcre2_match() was called with a null context, default
memory allocation functions were used instead of whatever was used when the
pattern was compiled.
17. Changes to the pcre2test "memory" modifier on a subject line. These apply
only to pcre2_match():
(a) Warn if null_context is set on both pattern and subject, because the
memory details cannot then be shown.
(b) Remember (up to a certain number of) memory allocations and their
lengths, and list only the lengths, so as to be system-independent.
(In practice, the new interpreter never has more than 2 blocks allocated
simultaneously.)
18. Make pcre2test detect an error return from pcre2_get_error_message(), give
a message, and abandon the run (this would have detected #13 above).
19. Implemented PCRE2_ENDANCHORED.
20. Applied Jason Hood's patches (slightly modified) to pcre2grep, to implement
the --output=text (-O) option and the inbuilt callout echo.
21. Extend auto-anchoring etc. to ignore groups with a zero qualifier and
single-branch conditions with a false condition (e.g. DEFINE) at the start of a
branch. For example, /(?(DEFINE)...)^A/ and /(...){0}^B/ are now flagged as
anchored.
22. Added an explicit limit on the amount of heap used by pcre2_match(), set by
pcre2_set_heap_limit() or (*LIMIT_HEAP=xxx). Upgraded pcre2test to show the
heap limit along with other pattern information, and to find the minimum when
the find_limits modifier is set.
23. Write to the last 8 bytes of the pcre2_real_code structure when a compiled
pattern is set up so as to initialize any padding the compiler might have
included. This avoids valgrind warnings when a compiled pattern is copied, in
particular when it is serialized.
24. Remove a redundant line of code left in accidentally a long time ago.
25. Remove a duplication typo in pcre2_tables.c
26. Correct an incorrect cast in pcre2_valid_utf.c
27. Update pcre2test, remove some unused code in pcre2_match(), and upgrade the
tests to improve coverage.
28. Some fixes/tidies as a result of looking at Coverity Scan output:
(a) Typo: ">" should be ">=" in opcode check in pcre2_auto_possess.c.
(b) Added some casts to avoid "suspicious implicit sign extension".
(c) Resource leaks in pcre2test in rare error cases.
(d) Avoid warning for never-use case OP_TABLE_LENGTH which is just a fudge
for checking at compile time that tables are the right size.
(e) Add missing "fall through" comment.
29. Implemented PCRE2_EXTENDED_MORE and related /xx and (?xx) features.
30. Implement (?n: for PCRE2_NO_AUTO_CAPTURE, because Perl now has this.
31. If more than one of "push", "pushcopy", or "pushtablescopy" were set in
pcre2test, a crash could occur.
32. Make -bigstack in RunTest allocate a 64MiB stack (instead of 16MiB) so
that all the tests can run with clang's sanitizing options.
33. Implement extra compile options in the compile context and add the first
one: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES.
34. Implement newline type PCRE2_NEWLINE_NUL.
35. A lookbehind assertion that had a zero-length branch caused undefined
behaviour when processed by pcre2_dfa_match(). This is oss-fuzz issue 1859.
36. The match limit value now also applies to pcre2_dfa_match() as there are
patterns that can use up a lot of resources without necessarily recursing very
deeply. (Compare item 10.23/36.) This should fix oss-fuzz #1761.
37. Implement PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL.
38. Fix returned offsets from regexec() when REG_STARTEND is used with a
starting offset greater than zero.
39. Implement REG_PEND (GNU extension) for the POSIX wrapper.
40. Implement the subject_literal modifier in pcre2test, and allow jitstack on
pattern lines.
41. Implement PCRE2_LITERAL and use it to support REG_NOSPEC.
42. Implement PCRE2_EXTRA_MATCH_LINE and PCRE2_EXTRA_MATCH_WORD for the benefit
of pcre2grep.
43. Re-implement pcre2grep's -F, -w, and -x options using PCRE2_LITERAL,
PCRE2_EXTRA_MATCH_WORD, and PCRE2_EXTRA_MATCH_LINE. This fixes two bugs:
(a) The -F option did not work for fixed strings containing \E.
(b) The -w option did not work for patterns with multiple branches.
44. Added configuration options for the SELinux compatible execmem allocator in
JIT.
45. Increased the limit for searching for a "must be present" code unit in
subjects from 1000 to 2000 for 8-bit searches, since they use memchr() and are
much faster.
46. Arrange for anchored patterns to record and use "first code unit" data,
because this can give a fast "no match" without searching for a "required code
unit". Previously only non-anchored patterns did this.
47. Upgraded the Unicode tables from Unicode 8.0.0 to Unicode 10.0.0.
48. Add the callout_no_where modifier to pcre2test.
49. Update extended grapheme breaking rules to the latest set that are in
Unicode Standard Annex #29.
50. Added experimental foreign pattern conversion facilities
(pcre2_pattern_convert() and friends).
51. Change the macro FWRITE, used in pcre2grep, to FWRITE_IGNORE because FWRITE
is defined in a system header in cygwin. Also modified some of the #ifdefs in
pcre2grep related to Windows and Cygwin support.
52. Change 3(g) for 10.23 was a bit too zealous. If a hyphen that follows a
character class is the last character in the class, Perl does not give a
warning. PCRE2 now also treats this as a literal.
53. Related to 52, though PCRE2 was throwing an error for [[:digit:]-X] it was
not doing so for [\d-X] (and similar escapes), as is documented.
54. Fixed a MIPS issue in the JIT compiler reported by Joshua Kinard.
55. Fixed a "maybe uninitialized" warning for class_uchardata in \p handling in
pcre2_compile() which could never actually trigger (code should have been cut
out when Unicode support is disabled).
Version 10.23 14-February-2017
------------------------------
1. Extended pcre2test with the utf8_input modifier so that it is able to
generate all possible 16-bit and 32-bit code unit values in non-UTF modes.
2. In any wide-character mode (8-bit UTF or any 16-bit or 32-bit mode), without
PCRE2_UCP set, a negative character type such as \D in a positive class should
cause all characters greater than 255 to match, whatever else is in the class.
There was a bug that caused this not to happen if a Unicode property item was
added to such a class, for example [\D\P{Nd}] or [\W\pL].
3. There has been a major re-factoring of the pcre2_compile.c file. Most syntax
checking is now done in the pre-pass that identifies capturing groups. This has
reduced the amount of duplication and made the code tidier. While doing this,
some minor bugs and Perl incompatibilities were fixed, including:
(a) \Q\E in the middle of a quantifier such as A+\Q\E+ is now ignored instead
of giving an invalid quantifier error.
(b) {0} can now be used after a group in a lookbehind assertion; previously
this caused an "assertion is not fixed length" error.
(c) Perl always treats (?(DEFINE) as a "define" group, even if a group with
the name "DEFINE" exists. PCRE2 now does likewise.
(d) A recursion condition test such as (?(R2)...) must now refer to an
existing subpattern.
(e) A conditional recursion test such as (?(R)...) misbehaved if there was a
group whose name began with "R".
(f) When testing zero-terminated patterns under valgrind, the terminating
zero is now marked "no access". This catches bugs that would otherwise
show up only with non-zero-terminated patterns.
(g) A hyphen appearing immediately after a POSIX character class (for example
/[[:ascii:]-z]/) now generates an error. Perl does accept this as a
literal, but gives a warning, so it seems best to fail it in PCRE.
(h) An empty \Q\E sequence may appear after a callout that precedes an
assertion condition (it is, of course, ignored).
One effect of the refactoring is that some error numbers and messages have
changed, and the pattern offset given for compiling errors is not always the
right-most character that has been read. In particular, for a variable-length
lookbehind assertion it now points to the start of the assertion. Another
change is that when a callout appears before a group, the "length of next
pattern item" that is passed now just gives the length of the opening
parenthesis item, not the length of the whole group. A length of zero is now
given only for a callout at the end of the pattern. Automatic callouts are no
longer inserted before and after explicit callouts in the pattern.
A number of bugs in the refactored code were subsequently fixed during testing
before release, but after the code was made available in the repository. Many
of the bugs were discovered by fuzzing testing. Several of them were related to
the change from assuming a zero-terminated pattern (which previously had
required non-zero terminated strings to be copied). These bugs were never in
fully released code, but are noted here for the record.
(a) An overall recursion such as (?0) inside a lookbehind assertion was not
being diagnosed as an error.
(b) In utf mode, the length of a *MARK (or other verb) name was being checked
in characters instead of code units, which could lead to bad code being
compiled, leading to unpredictable behaviour.
(c) In extended /x mode, characters whose code was greater than 255 caused
a lookup outside one of the global tables. A similar bug existed for wide
characters in *VERB names.
(d) The amount of memory needed for a compiled pattern was miscalculated if a
lookbehind contained more than one toplevel branch and the first branch
was of length zero.
(e) In UTF-8 or UTF-16 modes with PCRE2_EXTENDED (/x) set and a non-zero-
terminated pattern, if a # comment ran on to the end of the pattern, one
or more code units past the end were being read.
(f) An unterminated repeat at the end of a non-zero-terminated pattern (e.g.
"{2,2") could cause reading beyond the pattern.
(g) When reading a callout string, if the end delimiter was at the end of the
pattern one further code unit was read.
(h) An unterminated number after \g' could cause reading beyond the pattern.
(i) An insufficient memory size was being computed for compiling with
PCRE2_AUTO_CALLOUT.
(j) A conditional group with an assertion condition used more memory than was
allowed for it during parsing, so too many of them could therefore
overrun a buffer.
(k) If parsing a pattern exactly filled the buffer, the internal test for
overrun did not check when the final META_END item was added.
(l) If a lookbehind contained a subroutine call, and the called group
contained an option setting such as (?s), and the PCRE2_ANCHORED option
was set, unpredictable behaviour could occur. The underlying bug was
incorrect code and insufficient checking while searching for the end of
the called subroutine in the parsed pattern.
(m) Quantifiers following (*VERB)s were not being diagnosed as errors.
(n) The use of \Q...\E in a (*VERB) name when PCRE2_ALT_VERBNAMES and
PCRE2_AUTO_CALLOUT were both specified caused undetermined behaviour.
(o) If \Q was preceded by a quantified item, and the following \E was
followed by '?' or '+', and there was at least one literal character
between them, an internal error "unexpected repeat" occurred (example:
/.+\QX\E+/).
(p) A buffer overflow could occur while sorting the names in the group name
list (depending on the order in which the names were seen).
(q) A conditional group that started with a callout was not doing the right
check for a following assertion, leading to compiling bad code. Example:
/(?(C'XX))?!XX/
(r) If a character whose code point was greater than 0xffff appeared within
a lookbehind that was within another lookbehind, the calculation of the
lookbehind length went wrong and could provoke an internal error.
(t) The sequence \E- or \Q\E- after a POSIX class in a character class caused
an internal error. Now the hyphen is treated as a literal.
4. Back references are now permitted in lookbehind assertions when there are
no duplicated group numbers (that is, (?| has not been used), and, if the
reference is by name, there is only one group of that name. The referenced
group must, of course be of fixed length.
5. pcre2test has been upgraded so that, when run under valgrind with valgrind
support enabled, reading past the end of the pattern is detected, both when
compiling and during callout processing.
6. \g{+<number>} (e.g. \g{+2} ) is now supported. It is a "forward back
reference" and can be useful in repetitions (compare \g{-<number>} ). Perl does
not recognize this syntax.
7. Automatic callouts are no longer generated before and after callouts in the
pattern.
8. When pcre2test was outputting information from a callout, the caret indicator
for the current position in the subject line was incorrect if it was after an
escape sequence for a character whose code point was greater than \x{ff}.
9. Change 19 for 10.22 had a typo (PCRE_STATIC_RUNTIME should be
PCRE2_STATIC_RUNTIME). Fix from David Gaussmann.
10. Added --max-buffer-size to pcre2grep, to allow for automatic buffer
expansion when long lines are encountered. Original patch by Dmitry
Cherniachenko.
11. If pcre2grep was compiled with JIT support, but the library was compiled
without it (something that neither ./configure nor CMake allow, but it can be
done by editing config.h), pcre2grep was giving a JIT error. Now it detects
this situation and does not try to use JIT.
12. Added some "const" qualifiers to variables in pcre2grep.
13. Added Dmitry Cherniachenko's patch for colouring output in Windows
(untested by me). Also, look for GREP_COLOUR or GREP_COLOR if the environment
variables PCRE2GREP_COLOUR and PCRE2GREP_COLOR are not found.
14. Add the -t (grand total) option to pcre2grep.
15. A number of bugs have been mended relating to match start-up optimizations
when the first thing in a pattern is a positive lookahead. These all applied
only when PCRE2_NO_START_OPTIMIZE was *not* set:
(a) A pattern such as (?=.*X)X$ was incorrectly optimized as if it needed
both an initial 'X' and a following 'X'.
(b) Some patterns starting with an assertion that started with .* were
incorrectly optimized as having to match at the start of the subject or
after a newline. There are cases where this is not true, for example,
(?=.*[A-Z])(?=.{8,16})(?!.*[\s]) matches after the start in lines that
start with spaces. Starting .* in an assertion is no longer taken as an
indication of matching at the start (or after a newline).
16. The "offset" modifier in pcre2test was not being ignored (as documented)
when the POSIX API was in use.
17. Added --enable-fuzz-support to "configure", causing an non-installed
library containing a test function that can be called by fuzzers to be
compiled. A non-installed binary to run the test function locally, called
pcre2fuzzcheck is also compiled.
18. A pattern with PCRE2_DOTALL (/s) set but not PCRE2_NO_DOTSTAR_ANCHOR, and
which started with .* inside a positive lookahead was incorrectly being
compiled as implicitly anchored.
19. Removed all instances of "register" declarations, as they are considered
obsolete these days and in any case had become very haphazard.
20. Add strerror() to pcre2test for failed file opening.
21. Make pcre2test -C list valgrind support when it is enabled.
22. Add the use_length modifier to pcre2test.
23. Fix an off-by-one bug in pcre2test for the list of names for 'get' and
'copy' modifiers.
24. Add PCRE2_CALL_CONVENTION into the prototype declarations in pcre2.h as it
is apparently needed there as well as in the function definitions. (Why did
nobody ask for this in PCRE1?)
25. Change the _PCRE2_H and _PCRE2_UCP_H guard macros in the header files to
PCRE2_H_IDEMPOTENT_GUARD and PCRE2_UCP_H_IDEMPOTENT_GUARD to be more standard
compliant and unique.
26. pcre2-config --libs-posix was listing -lpcre2posix instead of
-lpcre2-posix. Also, the CMake build process was building the library with the
wrong name.
27. In pcre2test, give some offset information for errors in hex patterns.
This uses the C99 formatting sequence %td, except for MSVC which doesn't
support it - %lu is used instead.
28. Implemented pcre2_code_copy_with_tables(), and added pushtablescopy to
pcre2test for testing it.
29. Fix small memory leak in pcre2test.
30. Fix out-of-bounds read for partial matching of /./ against an empty string
when the newline type is CRLF.
31. Fix a bug in pcre2test that caused a crash when a locale was set either in
the current pattern or a previous one and a wide character was matched.
32. The appearance of \p, \P, or \X in a substitution string when
PCRE2_SUBSTITUTE_EXTENDED was set caused a segmentation fault (NULL
dereference).
33. If the starting offset was specified as greater than the subject length in
a call to pcre2_substitute() an out-of-bounds memory reference could occur.
34. When PCRE2 was compiled to use the heap instead of the stack for recursive
calls to match(), a repeated minimizing caseless back reference, or a
maximizing one where the two cases had different numbers of code units,
followed by a caseful back reference, could lose the caselessness of the first
repeated back reference (example: /(Z)(a)\2{1,2}?(?-i)\1X/i should match ZaAAZX
but didn't).
35. When a pattern is too complicated, PCRE2 gives up trying to find a minimum
matching length and just records zero. Typically this happens when there are
too many nested or recursive back references. If the limit was reached in
certain recursive cases it failed to be triggered and an internal error could
be the result.
36. The pcre2_dfa_match() function now takes note of the recursion limit for
the internal recursive calls that are used for lookrounds and recursions within
the pattern.
37. More refactoring has got rid of the internal could_be_empty_branch()
function (around 400 lines of code, including comments) by keeping track of
could-be-emptiness as the pattern is compiled instead of scanning compiled
groups. (This would have been much harder before the refactoring of #3 above.)
This lifts a restriction on the number of branches in a group (more than about
1100 would give "pattern is too complicated").
38. Add the "-ac" command line option to pcre2test as a synonym for "-pattern
auto_callout".
39. In a library with Unicode support, incorrect data was compiled for a
pattern with PCRE2_UCP set without PCRE2_UTF if a class required all wide
characters to match (for example, /[\s[:^ascii:]]/).
40. The callout_error modifier has been added to pcre2test to make it possible
to return PCRE2_ERROR_CALLOUT from a callout.
41. A minor change to pcre2grep: colour reset is now "<esc>[0m" instead of
"<esc>[00m".
42. The limit in the auto-possessification code that was intended to catch
overly-complicated patterns and not spend too much time auto-possessifying was
being reset too often, resulting in very long compile times for some patterns.
Now such patterns are no longer completely auto-possessified.
43. Applied Jason Hood's revised patch for RunTest.bat.
44. Added a new Windows script RunGrepTest.bat, courtesy of Jason Hood.
45. Minor cosmetic fix to pcre2test: move a variable that is not used under
Windows into the "not Windows" code.
46. Applied Jason Hood's patches to upgrade pcre2grep under Windows and tidy
some of the code:
* normalised the Windows condition by ensuring WIN32 is defined;
* enables the callout feature under Windows;
* adds globbing (Microsoft's implementation expands quoted args),
using a tweaked opendirectory;
* implements the is_*_tty functions for Windows;
* --color=always will write the ANSI sequences to file;
* add sequences 4 (underline works on Win10) and 5 (blink as bright
background, relatively standard on DOS/Win);
* remove the (char *) casts for the now-const strings;
* remove GREP_COLOUR (grep's command line allowed the 'u', but not
the environment), parsing GREP_COLORS instead;
* uses the current colour if not set, rather than black;
* add print_match for the undefined case;
* fixes a typo.
In addition, colour settings containing anything other than digits and
semicolon are ignored, and the colour controls are no longer output for empty
strings.
47. Detecting patterns that are too large inside the length-measuring loop
saves processing ridiculously long patterns to their end.
48. Ignore PCRE2_CASELESS when processing \h, \H, \v, and \V in classes as it
just wastes time. In the UTF case it can also produce redundant entries in
XCLASS lists caused by characters with multiple other cases and pairs of
characters in the same "not-x" sublists.
49. A pattern such as /(?=(a\K))/ can report the end of the match being before
its start; pcre2test was not handling this correctly when using the POSIX
interface (it was OK with the native interface).
50. In pcre2grep, ignore all JIT compile errors. This means that pcre2grep will
continue to work, falling back to interpretation if anything goes wrong with
JIT.
51. Applied patches from Christian Persch to configure.ac to make use of the
AC_USE_SYSTEM_EXTENSIONS macro and to test for functions used by the JIT
modules.
52. Minor fixes to pcre2grep from Jason Hood:
* fixed some spacing;
* Windows doesn't usually use single quotes, so I've added a define
to use appropriate quotes [in an example];
* LC_ALL was displayed as "LCC_ALL";
* numbers 11, 12 & 13 should end in "th";
* use double quotes in usage message.
53. When autopossessifying, skip empty branches without recursion, to reduce
stack usage for the benefit of clang with -fsanitize-address, which uses huge
stack frames. Example pattern: /X?(R||){3335}/. Fixes oss-fuzz issue 553.
54. A pattern with very many explicit back references to a group that is a long
way from the start of the pattern could take a long time to compile because
searching for the referenced group in order to find the minimum length was
being done repeatedly. Now up to 128 group minimum lengths are cached and the
attempt to find a minimum length is abandoned if there is a back reference to a
group whose number is greater than 128. (In that case, the pattern is so
complicated that this optimization probably isn't worth it.) This fixes
oss-fuzz issue 557.
55. Issue 32 for 10.22 below was not correctly fixed. If pcre2grep in multiline
mode with --only-matching matched several lines, it restarted scanning at the
next line instead of moving on to the end of the matched string, which can be
several lines after the start.
56. Applied Jason Hood's new patch for RunGrepTest.bat that updates it in line
with updates to the non-Windows version.
Version 10.22 29-July-2016
--------------------------
1. Applied Jason Hood's patches to RunTest.bat and testdata/wintestoutput3
to fix problems with running the tests under Windows.
2. Implemented a facility for quoting literal characters within hexadecimal
patterns in pcre2test, to make it easier to create patterns with just a few
non-printing characters.
3. Binary zeros are not supported in pcre2test input files. It now detects them
and gives an error.
4. Updated the valgrind parameters in RunTest: (a) changed smc-check=all to
smc-check=all-non-file; (b) changed obj:* in the suppression file to obj:??? so
that it matches only unknown objects.
5. Updated the maintenance script maint/ManyConfigTests to make it easier to
select individual groups of tests.
6. When the POSIX wrapper function regcomp() is called, the REG_NOSUB option
used to set PCRE2_NO_AUTO_CAPTURE when calling pcre2_compile(). However, this
disables the use of back references (and subroutine calls), which are supported
by other implementations of regcomp() with RE_NOSUB. Therefore, REG_NOSUB no
longer causes PCRE2_NO_AUTO_CAPTURE to be set, though it still ignores nmatch
and pmatch when regexec() is called.
7. Because of 6 above, pcre2test has been modified with a new modifier called
posix_nosub, to call regcomp() with REG_NOSUB. Previously the no_auto_capture
modifier had this effect. That option is now ignored when the POSIX API is in
use.
8. Minor tidies to the pcre2demo.c sample program, including more comments
about its 8-bit-ness.
9. Detect unmatched closing parentheses and give the error in the pre-scan
instead of later. Previously the pre-scan carried on and could give a
misleading incorrect error message. For example, /(?J)(?'a'))(?'a')/ gave a
message about invalid duplicate group names.
10. It has happened that pcre2test was accidentally linked with another POSIX
regex library instead of libpcre2-posix. In this situation, a call to regcomp()
(in the other library) may succeed, returning zero, but of course putting its
own data into the regex_t block. In one example the re_pcre2_code field was
left as NULL, which made pcre2test think it had not got a compiled POSIX regex,
so it treated the next line as another pattern line, resulting in a confusing
error message. A check has been added to pcre2test to see if the data returned
from a successful call of regcomp() are valid for PCRE2's regcomp(). If they
are not, an error message is output and the pcre2test run is abandoned. The
message points out the possibility of a mis-linking. Hopefully this will avoid
some head-scratching the next time this happens.
11. A pattern such as /(?<=((?C)0))/, which has a callout inside a lookbehind
assertion, caused pcre2test to output a very large number of spaces when the
callout was taken, making the program appearing to loop.
12. A pattern that included (*ACCEPT) in the middle of a sufficiently deeply
nested set of parentheses of sufficient size caused an overflow of the
compiling workspace (which was diagnosed, but of course is not desirable).
13. Detect missing closing parentheses during the pre-pass for group
identification.
14. Changed some integer variable types and put in a number of casts, following
a report of compiler warnings from Visual Studio 2013 and a few tests with
gcc's -Wconversion (which still throws up a lot).
15. Implemented pcre2_code_copy(), and added pushcopy and #popcopy to pcre2test
for testing it.
16. Change 66 for 10.21 introduced the use of snprintf() in PCRE2's version of
regerror(). When the error buffer is too small, my version of snprintf() puts a
binary zero in the final byte. Bug #1801 seems to show that other versions do
not do this, leading to bad output from pcre2test when it was checking for
buffer overflow. It no longer assumes a binary zero at the end of a too-small
regerror() buffer.
17. Fixed typo ("&&" for "&") in pcre2_study(). Fortunately, this could not
actually affect anything, by sheer luck.
18. Two minor fixes for MSVC compilation: (a) removal of apparently incorrect
"const" qualifiers in pcre2test and (b) defining snprintf as _snprintf for
older MSVC compilers. This has been done both in src/pcre2_internal.h for most
of the library, and also in src/pcre2posix.c, which no longer includes
pcre2_internal.h (see 24 below).
19. Applied Chris Wilson's patch (Bugzilla #1681) to CMakeLists.txt for MSVC
static compilation. Subsequently applied Chris Wilson's second patch, putting
the first patch under a new option instead of being unconditional when
PCRE_STATIC is set.
20. Updated pcre2grep to set stdout as binary when run under Windows, so as not
to convert \r\n at the ends of reflected lines into \r\r\n. This required
ensuring that other output that is written to stdout (e.g. file names) uses the
appropriate line terminator: \r\n for Windows, \n otherwise.
21. When a line is too long for pcre2grep's internal buffer, show the maximum
length in the error message.
22. Added support for string callouts to pcre2grep (Zoltan's patch with PH
additions).
23. RunTest.bat was missing a "set type" line for test 22.
24. The pcre2posix.c file was including pcre2_internal.h, and using some
"private" knowledge of the data structures. This is unnecessary; the code has
been re-factored and no longer includes pcre2_internal.h.
25. A racing condition is fixed in JIT reported by Mozilla.
26. Minor code refactor to avoid "array subscript is below array bounds"
compiler warning.
27. Minor code refactor to avoid "left shift of negative number" warning.
28. Add a bit more sanity checking to pcre2_serialize_decode() and document
that it expects trusted data.
29. Fix typo in pcre2_jit_test.c
30. Due to an oversight, pcre2grep was not making use of JIT when available.
This is now fixed.
31. The RunGrepTest script is updated to use the valgrind suppressions file
when testing with JIT under valgrind (compare 10.21/51 below). The suppressions
file is updated so that is now the same as for PCRE1: it suppresses the
Memcheck warnings Addr16 and Cond in unknown objects (that is, JIT-compiled
code). Also changed smc-check=all to smc-check=all-non-file as was done for
RunTest (see 4 above).
32. Implemented the PCRE2_NO_JIT option for pcre2_match().
33. Fix typo that gave a compiler error when JIT not supported.
34. Fix comment describing the returns from find_fixedlength().
35. Fix potential negative index in pcre2test.
36. Calls to pcre2_get_error_message() with error numbers that are never
returned by PCRE2 functions were returning empty strings. Now the error code
PCRE2_ERROR_BADDATA is returned. A facility has been added to pcre2test to
show the texts for given error numbers (i.e. to call pcre2_get_error_message()
and display what it returns) and a few representative error codes are now
checked in RunTest.
37. Added "&& !defined(__INTEL_COMPILER)" to the test for __GNUC__ in
pcre2_match.c, in anticipation that this is needed for the same reason it was
recently added to pcrecpp.cc in PCRE1.
38. Using -o with -M in pcre2grep could cause unnecessary repeated output when
the match extended over a line boundary, as it tried to find more matches "on
the same line" - but it was already over the end.
39. Allow \C in lookbehinds and DFA matching in UTF-32 mode (by converting it
to the same code as '.' when PCRE2_DOTALL is set).
40. Fix two clang compiler warnings in pcre2test when only one code unit width
is supported.
41. Upgrade RunTest to automatically re-run test 2 with a large (64MiB) stack
if it fails when running the interpreter with a 16MiB stack (and if changing
the stack size via pcre2test is possible). This avoids having to manually set a
large stack size when testing with clang.
42. Fix register overwrite in JIT when SSE2 acceleration is enabled.
43. Detect integer overflow in pcre2test pattern and data repetition counts.
44. In pcre2test, ignore "allcaptures" after DFA matching.
45. Fix unaligned accesses on x86. Patch by Marc Mutz.
46. Fix some more clang compiler warnings.
Version 10.21 12-January-2016
-----------------------------
1. Improve matching speed of patterns starting with + or * in JIT.
2. Use memchr() to find the first character in an unanchored match in 8-bit
mode in the interpreter. This gives a significant speed improvement.
3. Removed a redundant copy of the opcode_possessify table in the
pcre2_auto_possessify.c source.
4. Fix typos in dftables.c for z/OS.
5. Change 36 for 10.20 broke the handling of [[:>:]] and [[:<:]] in that
processing them could involve a buffer overflow if the following character was
an opening parenthesis.
6. Change 36 for 10.20 also introduced a bug in processing this pattern:
/((?x)(*:0))#(?'/. Specifically: if a setting of (?x) was followed by a (*MARK)
setting (which (*:0) is), then (?x) did not get unset at the end of its group
during the scan for named groups, and hence the external # was incorrectly
treated as a comment and the invalid (?' at the end of the pattern was not
diagnosed. This caused a buffer overflow during the real compile. This bug was
discovered by Karl Skomski with the LLVM fuzzer.
7. Moved the pcre2_find_bracket() function from src/pcre2_compile.c into its
own source module to avoid a circular dependency between src/pcre2_compile.c
and src/pcre2_study.c
8. A callout with a string argument containing an opening square bracket, for
example /(?C$[$)(?<]/, was incorrectly processed and could provoke a buffer
overflow. This bug was discovered by Karl Skomski with the LLVM fuzzer.
9. The handling of callouts during the pre-pass for named group identification
has been tightened up.
10. The quantifier {1} can be ignored, whether greedy, non-greedy, or
possessive. This is a very minor optimization.
11. A possessively repeated conditional group that could match an empty string,
for example, /(?(R))*+/, was incorrectly compiled.
12. The Unicode tables have been updated to Unicode 8.0.0 (thanks to Christian
Persch).
13. An empty comment (?#) in a pattern was incorrectly processed and could
provoke a buffer overflow. This bug was discovered by Karl Skomski with the
LLVM fuzzer.
14. Fix infinite recursion in the JIT compiler when certain patterns such as
/(?:|a|){100}x/ are analysed.
15. Some patterns with character classes involving [: and \\ were incorrectly
compiled and could cause reading from uninitialized memory or an incorrect
error diagnosis. Examples are: /[[:\\](?<[::]/ and /[[:\\](?'abc')[a:]. The
first of these bugs was discovered by Karl Skomski with the LLVM fuzzer.
16. Pathological patterns containing many nested occurrences of [: caused
pcre2_compile() to run for a very long time. This bug was found by the LLVM
fuzzer.
17. A missing closing parenthesis for a callout with a string argument was not
being diagnosed, possibly leading to a buffer overflow. This bug was found by
the LLVM fuzzer.
18. A conditional group with only one branch has an implicit empty alternative
branch and must therefore be treated as potentially matching an empty string.
19. If (?R was followed by - or + incorrect behaviour happened instead of a
diagnostic. This bug was discovered by Karl Skomski with the LLVM fuzzer.
20. Another bug that was introduced by change 36 for 10.20: conditional groups
whose condition was an assertion preceded by an explicit callout with a string
argument might be incorrectly processed, especially if the string contained \Q.
This bug was discovered by Karl Skomski with the LLVM fuzzer.
21. Compiling PCRE2 with the sanitize options of clang showed up a number of
very pedantic coding infelicities and a buffer overflow while checking a UTF-8
string if the final multi-byte UTF-8 character was truncated.
22. For Perl compatibility in EBCDIC environments, ranges such as a-z in a
class, where both values are literal letters in the same case, omit the
non-letter EBCDIC code points within the range.
23. Finding the minimum matching length of complex patterns with back
references and/or recursions can take a long time. There is now a cut-off that
gives up trying to find a minimum length when things get too complex.
24. An optimization has been added that speeds up finding the minimum matching
length for patterns containing repeated capturing groups or recursions.
25. If a pattern contained a back reference to a group whose number was
duplicated as a result of appearing in a (?|...) group, the computation of the
minimum matching length gave a wrong result, which could cause incorrect "no
match" errors. For such patterns, a minimum matching length cannot at present
be computed.
26. Added a check for integer overflow in conditions (?(<digits>) and
(?(R<digits>). This omission was discovered by Karl Skomski with the LLVM
fuzzer.
27. Fixed an issue when \p{Any} inside an xclass did not read the current
character.
28. If pcre2grep was given the -q option with -c or -l, or when handling a
binary file, it incorrectly wrote output to stdout.
29. The JIT compiler did not restore the control verb head in case of *THEN
control verbs. This issue was found by Karl Skomski with a custom LLVM fuzzer.
30. The way recursive references such as (?3) are compiled has been re-written
because the old way was the cause of many issues. Now, conversion of the group
number into a pattern offset does not happen until the pattern has been
completely compiled. This does mean that detection of all infinitely looping
recursions is postponed till match time. In the past, some easy ones were
detected at compile time. This re-writing was done in response to yet another
bug found by the LLVM fuzzer.
31. A test for a back reference to a non-existent group was missing for items
such as \987. This caused incorrect code to be compiled. This issue was found
by Karl Skomski with a custom LLVM fuzzer.
32. Error messages for syntax errors following \g and \k were giving inaccurate
offsets in the pattern.
33. Improve the performance of starting single character repetitions in JIT.
34. (*LIMIT_MATCH=) now gives an error instead of setting the value to 0.
35. Error messages for syntax errors in *LIMIT_MATCH and *LIMIT_RECURSION now
give the right offset instead of zero.
36. The JIT compiler should not check repeats after a {0,1} repeat byte code.
This issue was found by Karl Skomski with a custom LLVM fuzzer.
37. The JIT compiler should restore the control chain for empty possessive
repeats. This issue was found by Karl Skomski with a custom LLVM fuzzer.
38. A bug which was introduced by the single character repetition optimization
was fixed.
39. Match limit check added to recursion. This issue was found by Karl Skomski
with a custom LLVM fuzzer.
40. Arrange for the UTF check in pcre2_match() and pcre2_dfa_match() to look
only at the part of the subject that is relevant when the starting offset is
non-zero.
41. Improve first character match in JIT with SSE2 on x86.
42. Fix two assertion fails in JIT. These issues were found by Karl Skomski
with a custom LLVM fuzzer.
43. Correct the setting of CMAKE_C_FLAGS in CMakeLists.txt (patch from Roy Ivy
III).
44. Fix bug in RunTest.bat for new test 14, and adjust the script for the added
test (there are now 20 in total).
45. Fixed a corner case of range optimization in JIT.
46. Add the ${*MARK} facility to pcre2_substitute().
47. Modifier lists in pcre2test were splitting at spaces without the required
commas.
48. Implemented PCRE2_ALT_VERBNAMES.
49. Fixed two issues in JIT. These were found by Karl Skomski with a custom
LLVM fuzzer.
50. The pcre2test program has been extended by adding the #newline_default
command. This has made it possible to run the standard tests when PCRE2 is
compiled with either CR or CRLF as the default newline convention. As part of
this work, the new command was added to several test files and the testing
scripts were modified. The pcre2grep tests can now also be run when there is no
LF in the default newline convention.
51. The RunTest script has been modified so that, when JIT is used and valgrind
is specified, a valgrind suppressions file is set up to ignore "Invalid read of
size 16" errors because these are false positives when the hardware supports
the SSE2 instruction set.
52. It is now possible to have comment lines amid the subject strings in
pcre2test (and perltest.sh) input.
53. Implemented PCRE2_USE_OFFSET_LIMIT and pcre2_set_offset_limit().
54. Add the null_context modifier to pcre2test so that calling pcre2_compile()
and the matching functions with NULL contexts can be tested.
55. Implemented PCRE2_SUBSTITUTE_EXTENDED.
56. In a character class such as [\W\p{Any}] where both a negative-type escape
("not a word character") and a property escape were present, the property
escape was being ignored.
57. Fixed integer overflow for patterns whose minimum matching length is very,
very large.
58. Implemented --never-backslash-C.
59. Change 55 above introduced a bug by which certain patterns provoked the
erroneous error "\ at end of pattern".
60. The special sequences [[:<:]] and [[:>:]] gave rise to incorrect compiling
errors or other strange effects if compiled in UCP mode. Found with libFuzzer
and AddressSanitizer.
61. Whitespace at the end of a pcre2test pattern line caused a spurious error
message if there were only single-character modifiers. It should be ignored.
62. The use of PCRE2_NO_AUTO_CAPTURE could cause incorrect compilation results
or segmentation errors for some patterns. Found with libFuzzer and
AddressSanitizer.
63. Very long names in (*MARK) or (*THEN) etc. items could provoke a buffer
overflow.
64. Improve error message for overly-complicated patterns.
65. Implemented an optional replication feature for patterns in pcre2test, to
make it easier to test long repetitive patterns. The tests for 63 above are
converted to use the new feature.
66. In the POSIX wrapper, if regerror() was given too small a buffer, it could
misbehave.
67. In pcre2_substitute() in UTF mode, the UTF validity check on the
replacement string was happening before the length setting when the replacement
string was zero-terminated.
68. In pcre2_substitute() in UTF mode, PCRE2_NO_UTF_CHECK can be set for the
second and subsequent calls to pcre2_match().
69. There was no check for integer overflow for a replacement group number in
pcre2_substitute(). An added check for a number greater than the largest group
number in the pattern means this is not now needed.
70. The PCRE2-specific VERSION condition didn't work correctly if only one
digit was given after the decimal point, or if more than two digits were given.
It now works with one or two digits, and gives a compile time error if more are
given.
71. In pcre2_substitute() there was the possibility of reading one code unit
beyond the end of the replacement string.
72. The code for checking a subject's UTF-32 validity for a pattern with a
lookbehind involved an out-of-bounds pointer, which could potentially cause
trouble in some environments.
73. The maximum lookbehind length was incorrectly calculated for patterns such
as /(?<=(a)(?-1))x/ which have a recursion within a backreference.
74. Give an error if a lookbehind assertion is longer than 65535 code units.
75. Give an error in pcre2_substitute() if a match ends before it starts (as a
result of the use of \K).
76. Check the length of subpattern names and the names in (*MARK:xx) etc.
dynamically to avoid the possibility of integer overflow.
77. Implement pcre2_set_max_pattern_length() so that programs can restrict the
size of patterns that they are prepared to handle.
78. (*NO_AUTO_POSSESS) was not working.
79. Adding group information caching improves the speed of compiling when
checking whether a group has a fixed length and/or could match an empty string,
especially when recursion or subroutine calls are involved. However, this
cannot be used when (?| is present in the pattern because the same number may
be used for groups of different sizes. To catch runaway patterns in this
situation, counts have been introduced to the functions that scan for empty
branches or compute fixed lengths.
80. Allow for the possibility of the size of the nest_save structure not being
a factor of the size of the compiling workspace (it currently is).
81. Check for integer overflow in minimum length calculation and cap it at
65535.
82. Small optimizations in code for finding the minimum matching length.
83. Lock out configuring for EBCDIC with non-8-bit libraries.
84. Test for error code <= 0 in regerror().
85. Check for too many replacements (more than INT_MAX) in pcre2_substitute().
86. Avoid the possibility of computing with an out-of-bounds pointer (though
not dereferencing it) while handling lookbehind assertions.
87. Failure to get memory for the match data in regcomp() is now given as a
regcomp() error instead of waiting for regexec() to pick it up.
88. In pcre2_substitute(), ensure that CRLF is not split when it is a valid
newline sequence.
89. Paranoid check in regcomp() for bad error code from pcre2_compile().
90. Run test 8 (internal offsets and code sizes) for link sizes 3 and 4 as well
as for link size 2.
91. Document that JIT has a limit on pattern size, and give more information
about JIT compile failures in pcre2test.
92. Implement PCRE2_INFO_HASBACKSLASHC.
93. Re-arrange valgrind support code in pcre2test to avoid spurious reports
with JIT (possibly caused by SSE2?).
94. Support offset_limit in JIT.
95. A sequence such as [[:punct:]b] that is, a POSIX character class followed
by a single ASCII character in a class item, was incorrectly compiled in UCP
mode. The POSIX class got lost, but only if the single character followed it.
96. [:punct:] in UCP mode was matching some characters in the range 128-255
that should not have been matched.
97. If [:^ascii:] or [:^xdigit:] are present in a non-negated class, all
characters with code points greater than 255 are in the class. When a Unicode
property was also in the class (if PCRE2_UCP is set, escapes such as \w are
turned into Unicode properties), wide characters were not correctly handled,
and could fail to match.
98. In pcre2test, make the "startoffset" modifier a synonym of "offset",
because it sets the "startoffset" parameter for pcre2_match().
99. If PCRE2_AUTO_CALLOUT was set on a pattern that had a (?# comment between
an item and its qualifier (for example, A(?#comment)?B) pcre2_compile()
misbehaved. This bug was found by the LLVM fuzzer.
100. The error for an invalid UTF pattern string always gave the code unit
offset as zero instead of where the invalidity was found.
101. Further to 97 above, negated classes such as [^[:^ascii:]\d] were also not
working correctly in UCP mode.
102. Similar to 99 above, if an isolated \E was present between an item and its
qualifier when PCRE2_AUTO_CALLOUT was set, pcre2_compile() misbehaved. This bug
was found by the LLVM fuzzer.
103. The POSIX wrapper function regexec() crashed if the option REG_STARTEND
was set when the pmatch argument was NULL. It now returns REG_INVARG.
104. Allow for up to 32-bit numbers in the ordin() function in pcre2grep.
105. An empty \Q\E sequence between an item and its qualifier caused
pcre2_compile() to misbehave when auto callouts were enabled. This bug
was found by the LLVM fuzzer.
106. If both PCRE2_ALT_VERBNAMES and PCRE2_EXTENDED were set, and a (*MARK) or
other verb "name" ended with whitespace immediately before the closing
parenthesis, pcre2_compile() misbehaved. Example: /(*:abc )/, but only when
both those options were set.
107. In a number of places pcre2_compile() was not handling NULL characters
correctly, and pcre2test with the "bincode" modifier was not always correctly
displaying fields containing NULLS:
(a) Within /x extended #-comments
(b) Within the "name" part of (*MARK) and other *verbs
(c) Within the text argument of a callout
108. If a pattern that was compiled with PCRE2_EXTENDED started with white
space or a #-type comment that was followed by (?-x), which turns off
PCRE2_EXTENDED, and there was no subsequent (?x) to turn it on again,
pcre2_compile() assumed that (?-x) applied to the whole pattern and
consequently mis-compiled it. This bug was found by the LLVM fuzzer. The fix
for this bug means that a setting of any of the (?imsxJU) options at the start
of a pattern is no longer transferred to the options that are returned by
PCRE2_INFO_ALLOPTIONS. In fact, this was an anachronism that should have
changed when the effects of those options were all moved to compile time.
109. An escaped closing parenthesis in the "name" part of a (*verb) when
PCRE2_ALT_VERBNAMES was set caused pcre2_compile() to malfunction. This bug
was found by the LLVM fuzzer.
110. Implemented PCRE2_SUBSTITUTE_UNSET_EMPTY, and updated pcre2test to make it
possible to test it.
111. "Harden" pcre2test against ridiculously large values in modifiers and
command line arguments.
112. Implemented PCRE2_SUBSTITUTE_UNKNOWN_UNSET and PCRE2_SUBSTITUTE_OVERFLOW_
LENGTH.
113. Fix printing of *MARK names that contain binary zeroes in pcre2test.
Version 10.20 30-June-2015
--------------------------
1. Callouts with string arguments have been added.
2. Assertion code generator in JIT has been optimized.
3. The invalid pattern (?(?C) has a missing assertion condition at the end. The
pcre2_compile() function read past the end of the input before diagnosing an
error. This bug was discovered by the LLVM fuzzer.
4. Implemented pcre2_callout_enumerate().
5. Fix JIT compilation of conditional blocks whose assertion is converted to
(*FAIL). E.g: /(?(?!))/.
6. The pattern /(?(?!)^)/ caused references to random memory. This bug was
discovered by the LLVM fuzzer.
7. The assertion (?!) is optimized to (*FAIL). This was not handled correctly
when this assertion was used as a condition, for example (?(?!)a|b). In
pcre2_match() it worked by luck; in pcre2_dfa_match() it gave an incorrect
error about an unsupported item.
8. For some types of pattern, for example /Z*(|d*){216}/, the auto-
possessification code could take exponential time to complete. A recursion
depth limit of 1000 has been imposed to limit the resources used by this
optimization. This infelicity was discovered by the LLVM fuzzer.
9. A pattern such as /(*UTF)[\S\V\H]/, which contains a negated special class
such as \S in non-UCP mode, explicit wide characters (> 255) can be ignored
because \S ensures they are all in the class. The code for doing this was
interacting badly with the code for computing the amount of space needed to
compile the pattern, leading to a buffer overflow. This bug was discovered by
the LLVM fuzzer.
10. A pattern such as /((?2)+)((?1))/ which has mutual recursion nested inside
other kinds of group caused stack overflow at compile time. This bug was
discovered by the LLVM fuzzer.
11. A pattern such as /(?1)(?#?'){8}(a)/ which had a parenthesized comment
between a subroutine call and its quantifier was incorrectly compiled, leading
to buffer overflow or other errors. This bug was discovered by the LLVM fuzzer.
12. The illegal pattern /(?(?<E>.*!.*)?)/ was not being diagnosed as missing an
assertion after (?(. The code was failing to check the character after (?(?<
for the ! or = that would indicate a lookbehind assertion. This bug was
discovered by the LLVM fuzzer.
13. A pattern such as /X((?2)()*+){2}+/ which has a possessive quantifier with
a fixed maximum following a group that contains a subroutine reference was
incorrectly compiled and could trigger buffer overflow. This bug was discovered
by the LLVM fuzzer.
14. Negative relative recursive references such as (?-7) to non-existent
subpatterns were not being diagnosed and could lead to unpredictable behaviour.
This bug was discovered by the LLVM fuzzer.
15. The bug fixed in 14 was due to an integer variable that was unsigned when
it should have been signed. Some other "int" variables, having been checked,
have either been changed to uint32_t or commented as "must be signed".
16. A mutual recursion within a lookbehind assertion such as (?<=((?2))((?1)))
caused a stack overflow instead of the diagnosis of a non-fixed length
lookbehind assertion. This bug was discovered by the LLVM fuzzer.
17. The use of \K in a positive lookbehind assertion in a non-anchored pattern
(e.g. /(?<=\Ka)/) could make pcre2grep loop.
18. There was a similar problem to 17 in pcre2test for global matches, though
the code there did catch the loop.
19. If a greedy quantified \X was preceded by \C in UTF mode (e.g. \C\X*),
and a subsequent item in the pattern caused a non-match, backtracking over the
repeated \X did not stop, but carried on past the start of the subject, causing
reference to random memory and/or a segfault. There were also some other cases
where backtracking after \C could crash. This set of bugs was discovered by the
LLVM fuzzer.
20. The function for finding the minimum length of a matching string could take
a very long time if mutual recursion was present many times in a pattern, for
example, /((?2){73}(?2))((?1))/. A better mutual recursion detection method has
been implemented. This infelicity was discovered by the LLVM fuzzer.
21. Implemented PCRE2_NEVER_BACKSLASH_C.
22. The feature for string replication in pcre2test could read from freed
memory if the replication required a buffer to be extended, and it was not
working properly in 16-bit and 32-bit modes. This issue was discovered by a
fuzzer: see http://lcamtuf.coredump.cx/afl/.
23. Added the PCRE2_ALT_CIRCUMFLEX option.
24. Adjust the treatment of \8 and \9 to be the same as the current Perl
behaviour.
25. Static linking against the PCRE2 library using the pkg-config module was
failing on missing pthread symbols.
26. If a group that contained a recursive back reference also contained a
forward reference subroutine call followed by a non-forward-reference
subroutine call, for example /.((?2)(?R)\1)()/, pcre2_compile() failed to
compile correct code, leading to undefined behaviour or an internally detected
error. This bug was discovered by the LLVM fuzzer.
27. Quantification of certain items (e.g. atomic back references) could cause
incorrect code to be compiled when recursive forward references were involved.
For example, in this pattern: /(?1)()((((((\1++))\x85)+)|))/. This bug was
discovered by the LLVM fuzzer.
28. A repeated conditional group whose condition was a reference by name caused
a buffer overflow if there was more than one group with the given name. This
bug was discovered by the LLVM fuzzer.
29. A recursive back reference by name within a group that had the same name as
another group caused a buffer overflow. For example: /(?J)(?'d'(?'d'\g{d}))/.
This bug was discovered by the LLVM fuzzer.
30. A forward reference by name to a group whose number is the same as the
current group, for example in this pattern: /(?|(\k'Pm')|(?'Pm'))/, caused a
buffer overflow at compile time. This bug was discovered by the LLVM fuzzer.
31. Fix -fsanitize=undefined warnings for left shifts of 1 by 31 (it treats 1
as an int; fixed by writing it as 1u).
32. Fix pcre2grep compile when -std=c99 is used with gcc, though it still gives
a warning for "fileno" unless -std=gnu99 us used.
33. A lookbehind assertion within a set of mutually recursive subpatterns could
provoke a buffer overflow. This bug was discovered by the LLVM fuzzer.
34. Give an error for an empty subpattern name such as (?'').
35. Make pcre2test give an error if a pattern that follows #forbud_utf contains
\P, \p, or \X.
36. The way named subpatterns are handled has been refactored. There is now a
pre-pass over the regex which does nothing other than identify named
subpatterns and count the total captures. This means that information about
named patterns is known before the rest of the compile. In particular, it means
that forward references can be checked as they are encountered. Previously, the
code for handling forward references was contorted and led to several errors in
computing the memory requirements for some patterns, leading to buffer
overflows.
37. There was no check for integer overflow in subroutine calls such as (?123).
38. The table entry for \l in EBCDIC environments was incorrect, leading to its
being treated as a literal 'l' instead of causing an error.
39. If a non-capturing group containing a conditional group that could match
an empty string was repeated, it was not identified as matching an empty string
itself. For example: /^(?:(?(1)x|)+)+$()/.
40. In an EBCDIC environment, pcretest was mishandling the escape sequences
\a and \e in test subject lines.
41. In an EBCDIC environment, \a in a pattern was converted to the ASCII
instead of the EBCDIC value.
42. The handling of \c in an EBCDIC environment has been revised so that it is
now compatible with the specification in Perl's perlebcdic page.
43. Single character repetition in JIT has been improved. 20-30% speedup
was achieved on certain patterns.
44. The EBCDIC character 0x41 is a non-breaking space, equivalent to 0xa0 in
ASCII/Unicode. This has now been added to the list of characters that are
recognized as white space in EBCDIC.
45. When PCRE2 was compiled without Unicode support, the use of \p and \P gave
an error (correctly) when used outside a class, but did not give an error
within a class.
46. \h within a class was incorrectly compiled in EBCDIC environments.
47. JIT should return with error when the compiled pattern requires
more stack space than the maximum.
48. Fixed a memory leak in pcre2grep when a locale is set.
Version 10.10 06-March-2015
---------------------------
1. When a pattern is compiled, it remembers the highest back reference so that
when matching, if the ovector is too small, extra memory can be obtained to
use instead. A conditional subpattern whose condition is a check on a capture
having happened, such as, for example in the pattern /^(?:(a)|b)(?(1)A|B)/, is
another kind of back reference, but it was not setting the highest
backreference number. This mattered only if pcre2_match() was called with an
ovector that was too small to hold the capture, and there was no other kind of
back reference (a situation which is probably quite rare). The effect of the
bug was that the condition was always treated as FALSE when the capture could
not be consulted, leading to a incorrect behaviour by pcre2_match(). This bug
has been fixed.
2. Functions for serialization and deserialization of sets of compiled patterns
have been added.
3. The value that is returned by PCRE2_INFO_SIZE has been corrected to remove
excess code units at the end of the data block that may occasionally occur if
the code for calculating the size over-estimates. This change stops the
serialization code copying uninitialized data, to which valgrind objects. The
documentation of PCRE2_INFO_SIZE was incorrect in stating that the size did not
include the general overhead. This has been corrected.
4. All code units in every slot in the table of group names are now set, again
in order to avoid accessing uninitialized data when serializing.
5. The (*NO_JIT) feature is implemented.
6. If a bug that caused pcre2_compile() to use more memory than allocated was
triggered when using valgrind, the code in (3) above passed a stupidly large
value to valgrind. This caused a crash instead of an "internal error" return.
7. A reference to a duplicated named group (either a back reference or a test
for being set in a conditional) that occurred in a part of the pattern where
PCRE2_DUPNAMES was not set caused the amount of memory needed for the pattern
to be incorrectly calculated, leading to overwriting.
8. A mutually recursive set of back references such as (\2)(\1) caused a
segfault at compile time (while trying to find the minimum matching length).
The infinite loop is now broken (with the minimum length unset, that is, zero).
9. If an assertion that was used as a condition was quantified with a minimum
of zero, matching went wrong. In particular, if the whole group had unlimited
repetition and could match an empty string, a segfault was likely. The pattern
(?(?=0)?)+ is an example that caused this. Perl allows assertions to be
quantified, but not if they are being used as conditions, so the above pattern
is faulted by Perl. PCRE2 has now been changed so that it also rejects such
patterns.
10. The error message for an invalid quantifier has been changed from "nothing
to repeat" to "quantifier does not follow a repeatable item".
11. If a bad UTF string is compiled with NO_UTF_CHECK, it may succeed, but
scanning the compiled pattern in subsequent auto-possessification can get out
of step and lead to an unknown opcode. Previously this could have caused an
infinite loop. Now it generates an "internal error" error. This is a tidyup,
not a bug fix; passing bad UTF with NO_UTF_CHECK is documented as having an
undefined outcome.
12. A UTF pattern containing a "not" match of a non-ASCII character and a
subroutine reference could loop at compile time. Example: /[^\xff]((?1))/.
13. The locale test (RunTest 3) has been upgraded. It now checks that a locale
that is found in the output of "locale -a" can actually be set by pcre2test
before it is accepted. Previously, in an environment where a locale was listed
but would not set (an example does exist), the test would "pass" without
actually doing anything. Also the fr_CA locale has been added to the list of
locales that can be used.
14. Fixed a bug in pcre2_substitute(). If a replacement string ended in a
capturing group number without parentheses, the last character was incorrectly
literally included at the end of the replacement string.
15. A possessive capturing group such as (a)*+ with a minimum repeat of zero
failed to allow the zero-repeat case if pcre2_match() was called with an
ovector too small to capture the group.
16. Improved error message in pcre2test when setting the stack size (-S) fails.
17. Fixed two bugs in CMakeLists.txt: (1) Some lines had got lost in the
transfer from PCRE1, meaning that CMake configuration failed if "build tests"
was selected. (2) The file src/pcre2_serialize.c had not been added to the list
of PCRE2 sources, which caused a failure to build pcre2test.
18. Fixed typo in pcre2_serialize.c (DECL instead of DEFN) that causes problems
only on Windows.
19. Use binary input when reading back saved serialized patterns in pcre2test.
20. Added RunTest.bat for running the tests under Windows.
21. "make distclean" was not removing config.h, a file that may be created for
use with CMake.
22. A pattern such as "((?2){0,1999}())?", which has a group containing a
forward reference repeated a large (but limited) number of times within a
repeated outer group that has a zero minimum quantifier, caused incorrect code
to be compiled, leading to the error "internal error: previously-checked
referenced subpattern not found" when an incorrect memory address was read.
This bug was reported as "heap overflow", discovered by Kai Lu of Fortinet's
FortiGuard Labs. (Added 24-March-2015: CVE-2015-2325 was given to this.)
23. A pattern such as "((?+1)(\1))/" containing a forward reference subroutine
call within a group that also contained a recursive back reference caused
incorrect code to be compiled. This bug was reported as "heap overflow",
discovered by Kai Lu of Fortinet's FortiGuard Labs. (Added 24-March-2015:
CVE-2015-2326 was given to this.)
24. Computing the size of the JIT read-only data in advance has been a source
of various issues, and new ones are still appear unfortunately. To fix
existing and future issues, size computation is eliminated from the code,
and replaced by on-demand memory allocation.
25. A pattern such as /(?i)[A-`]/, where characters in the other case are
adjacent to the end of the range, and the range contained characters with more
than one other case, caused incorrect behaviour when compiled in UTF mode. In
that example, the range a-j was left out of the class.
Version 10.00 05-January-2015
-----------------------------
Version 10.00 is the first release of PCRE2, a revised API for the PCRE
library. Changes prior to 10.00 are logged in the ChangeLog file for the old
API, up to item 20 for release 8.36.
The code of the library was heavily revised as part of the new API
implementation. Details of each and every modification were not individually
logged. In addition to the API changes, the following changes were made. They
are either new functionality, or bug fixes and other noticeable changes of
behaviour that were implemented after the code had been forked.
1. Including Unicode support at build time is now enabled by default, but it
can optionally be disabled. It is not enabled by default at run time (no
change).
2. The test program, now called pcre2test, was re-specified and almost
completely re-written. Its input is not compatible with input for pcretest.
3. Patterns may start with (*NOTEMPTY) or (*NOTEMPTY_ATSTART) to set the
PCRE2_NOTEMPTY or PCRE2_NOTEMPTY_ATSTART options for every subject line that is
matched by that pattern.
4. For the benefit of those who use PCRE2 via some other application, that is,
not writing the function calls themselves, it is possible to check the PCRE2
version by matching a pattern such as /(?(VERSION>=10)yes|no)/ against a
string such as "yesno".
5. There are case-equivalent Unicode characters whose encodings use different
numbers of code units in UTF-8. U+023A and U+2C65 are one example. (It is
theoretically possible for this to happen in UTF-16 too.) If a backreference to
a group containing one of these characters was greedily repeated, and during
the match a backtrack occurred, the subject might be backtracked by the wrong
number of code units. For example, if /^(\x{23a})\1*(.)/ is matched caselessly
(and in UTF-8 mode) against "\x{23a}\x{2c65}\x{2c65}\x{2c65}", group 2 should
capture the final character, which is the three bytes E2, B1, and A5 in UTF-8.
Incorrect backtracking meant that group 2 captured only the last two bytes.
This bug has been fixed; the new code is slower, but it is used only when the
strings matched by the repetition are not all the same length.
6. A pattern such as /()a/ was not setting the "first character must be 'a'"
information. This applied to any pattern with a group that matched no
characters, for example: /(?:(?=.)|(?<!x))a/.
7. When an (*ACCEPT) is triggered inside capturing parentheses, it arranges for
those parentheses to be closed with whatever has been captured so far. However,
it was failing to mark any other groups between the highest capture so far and
the current group as "unset". Thus, the ovector for those groups contained
whatever was previously there. An example is the pattern /(x)|((*ACCEPT))/ when
matched against "abcd".
8. The pcre2_substitute() function has been implemented.
9. If an assertion used as a condition was quantified with a minimum of zero
(an odd thing to do, but it happened), SIGSEGV or other misbehaviour could
occur.
10. The PCRE2_NO_DOTSTAR_ANCHOR option has been implemented.

Technical notes about PCRE2
---------------------------
These are very rough technical notes that record potentially useful information
about PCRE2 internals. PCRE2 is a library based on the original PCRE library,
but with a revised (and incompatible) API. To avoid confusion, the original
library is referred to as PCRE1 below. For information about testing PCRE2, see
the pcre2test documentation and the comment at the head of the RunTest file.
PCRE1 releases were up to 8.3x when PCRE2 was developed, and later bug fix
releases carried on the 8.xx series, up to the final 8.45 release. PCRE2
releases started at 10.00 to avoid confusion with PCRE1.
Historical note 1
-----------------
Many years ago I implemented some regular expression functions to an algorithm
suggested by Martin Richards. The rather simple patterns were not Unix-like in
form, and were quite restricted in what they could do by comparison with Perl.
The interesting part about the algorithm was that the amount of space required
to hold the compiled form of an expression was known in advance. The code to
apply an expression did not operate by backtracking, as the original Henry
Spencer code and the current PCRE2 pcre2_match() function and Perl code do, but
instead checked all possibilities simultaneously by keeping a list of current
states and checking all of them as it advanced through the subject string. In
the terminology of Jeffrey Friedl's book, it was a "DFA algorithm", though it
was not a traditional Finite State Machine (FSM). When the pattern was all used
up, all remaining states were possible matches, and the one matching the
longest subset of the subject string was chosen. This did not necessarily
maximize the individual wild portions of the pattern, as is expected in Unix
and Perl-style regular expressions.
Historical note 2
-----------------
The code originally written by Henry Spencer (which was subsequently heavily
modified for Perl) compiles the expression twice: once in a dummy mode in order
to find out how much store will be needed, and then for real. (The Perl version
may or may not still do this; I'm talking about the original library.) The
execution function operates by backtracking and maximizing (or, optionally,
minimizing, in Perl) the amount of the subject that matches individual wild
portions of the pattern. This is an "NFA algorithm" in Friedl's terminology.
Support for 16-bit and 32-bit data strings
-------------------------------------------
The PCRE2 library can be compiled in any combination of 8-bit, 16-bit or 32-bit
modes, creating up to three different libraries. In the description that
follows, the word "short" is used for a 16-bit data quantity, and the phrase
"code unit" is used for a quantity that is a byte in 8-bit mode, a short in
16-bit mode and a 32-bit word in 32-bit mode. The names of PCRE2 functions are
given in generic form, without the _8, _16, or _32 suffix.
Computing the memory requirement: how it was
--------------------------------------------
Up to and including release 6.7, PCRE1 worked by running a very degenerate
first pass to calculate a maximum memory requirement, and then a second pass to
do the real compile - which might use a bit less than the predicted amount of
memory. The idea was that this would turn out faster than the Henry Spencer
code because the first pass is degenerate and the second pass can just store
stuff straight into memory, which it knows is big enough.
Computing the memory requirement: how it is
-------------------------------------------
By the time I was working on a potential 6.8 release, the degenerate first pass
had become very complicated and hard to maintain. Indeed one of the early
things I did for 6.8 was to fix Yet Another Bug in the memory computation. Then
I had a flash of inspiration as to how I could run the real compile function in
a "fake" mode that enables it to compute how much memory it would need, while
in most cases only ever using a small amount of working memory, and without too
many tests of the mode that might slow it down. So I refactored the compiling
functions to work this way. This got rid of about 600 lines of source and made
further maintenance and development easier. As this was such a major change, I
never released 6.8, instead upping the number to 7.0 (other quite major changes
were also present in the 7.0 release).
A side effect of this work was that the previous limit of 200 on the nesting
depth of parentheses was removed. However, there was a downside: compiling ran
more slowly than before (30% or more, depending on the pattern) because it now
did a full analysis of the pattern twice. My hope was that this would not be a
big issue, and in the event, nobody has commented on it.
At release 8.34, a limit on the nesting depth of parentheses was re-introduced
(default 250, settable at build time) so as to put a limit on the amount of
system stack used by the compile function, which uses recursive function calls
for nested parenthesized groups. This is a safety feature for environments with
small stacks where the patterns are provided by users.
Yet another pattern scan
------------------------
History repeated itself for PCRE2 release 10.20. A number of bugs relating to
named subpatterns had been discovered by fuzzers. Most of these were related to
the handling of forward references when it was not known if the named group was
unique. (References to non-unique names use a different opcode and more
memory.) The use of duplicate group numbers (the (?| facility) also caused
issues.
To get around these problems I adopted a new approach by adding a third pass
over the pattern (really a "pre-pass"), which does nothing other than identify
all the named subpatterns and their corresponding group numbers. This means
that the actual compile (both the memory-computing dummy run and the real
compile) has full knowledge of group names and numbers throughout. Several
dozen lines of messy code were eliminated, though the new pre-pass was not
short. In particular, parsing and skipping over [] classes is complicated.
While working on 10.22 I realized that I could simplify yet again by moving
more of the parsing into the pre-pass, thus avoiding doing it in two places, so
after 10.22 was released, the code underwent yet another big refactoring. This
is how it is from 10.23 onwards:
The function called parse_regex() scans the pattern characters, parsing them
into literal data and meta characters. It converts escapes such as \x{123}
into literals, handles \Q...\E, and skips over comments and non-significant
white space. The result of the scanning is put into a vector of 32-bit unsigned
integers. Values less than 0x80000000 are literal data. Higher values represent
meta-characters. The top 16-bits of such values identify the meta-character,
and these are given names such as META_CAPTURE. The lower 16-bits are available
for data, for example, the capturing group number. The only situation in which
literal data values greater than 0x7fffffff can appear is when the 32-bit
library is running in non-UTF mode. This is handled by having a special
meta-character that is followed by the 32-bit data value.
The size of the parsed pattern vector, when auto-callouts are not enabled, is
bounded by the length of the pattern (with one exception). The code is written
so that each item in the pattern uses no more vector elements than the number
of code units in the item itself. The exception is the aforementioned large
32-bit number handling. For this reason, 32-bit non-UTF patterns are scanned in
advance to check for such values. When auto-callouts are enabled, the generous
assumption is made that there will be a callout for each pattern code unit
(which of course is only actually true if all code units are literals) plus one
at the end. A default parsed pattern vector is defined on the system stack, to
minimize memory handling, but if this is not big enough, heap memory is used.
If there are any lookbehinds in the pattern, the parsed pattern is scanned in
order to work out their lengths. Then the actual compiling function is run
twice, the first time to determine the amount of memory needed for the final
compiled pattern. The compiling function processes the parsed pattern vector,
not the pattern itself, although some of the parsed items refer to strings in
the pattern - for example, group names.
Some post-processing of the compiled pattern takes place. If there are any
recursion or subroutine calls, there is a scan to convert them into offsets.
Then there are other scans to apply certain optimizations, some of which can be
disabled by setting appropriate options.
Most errors can be diagnosed during the parsing scan. For those that cannot,
the parsed code contains offsets into the pattern so that the actual compiling
code can report where the errors are.
The elements of the parsed pattern vector
-----------------------------------------
The word "offset" below means a code unit offset into the pattern. When
PCRE2_SIZE (which is usually size_t) is no bigger than uint32_t, an offset is
stored in a single parsed pattern element. Otherwise (typically on 64-bit
systems) it occupies two elements. The following meta items occupy just one
element, with no data:
META_ACCEPT (*ACCEPT)
META_ASTERISK *
META_ASTERISK_PLUS *+
META_ASTERISK_QUERY *?
META_ATOMIC (?> start of atomic group
META_CIRCUMFLEX ^ metacharacter
META_CLASS [ start of non-empty class
META_CLASS_EMPTY [] empty class - only with PCRE2_ALLOW_EMPTY_CLASS
META_CLASS_EMPTY_NOT [^] negative empty class - ditto
META_CLASS_END ] end of non-empty class
META_CLASS_NOT [^ start non-empty negative class
META_COMMIT (*COMMIT) - no argument (see below for with argument)
META_COND_ASSERT (?(?assertion)
META_DOLLAR $ metacharacter
META_DOT . metacharacter
META_END End of pattern (this value is 0x80000000)

The two RANGE values occur only in character classes. They are positioned
between two literals that define the start and end of the range. In an EBCDIC
environment it is necessary to know whether either of the range values was
specified as an escape. In an ASCII/Unicode environment the distinction is not
relevant.
The following have data in the lower 16 bits, and may be followed by other data
elements:
META_ALT | alternation
META_BACKREF back reference
META_CAPTURE start of capturing group
META_ESCAPE non-literal escape sequence
META_RECURSE recursion call
If the data for META_ALT is non-zero, it is inside a lookbehind, and the data
is the maximum length of its branch (see META_LOOKBEHIND below for more
detail).
META_BACKREF, META_CAPTURE, and META_RECURSE have the capture group number as
their data in the lower 16 bits of the element. META_RECURSE is followed by an
offset, for use in error messages.
META_BACKREF is followed by an offset if the back reference group number is 10
or more. The offsets of the first occurrences of references to groups whose
numbers are less than 10 are put in cb->small_ref_offset[] (only the first
occurrence is useful). On 64-bit systems this avoids using more than two parsed
pattern elements for items such as \3. The offset is used when an error occurs
because the reference is to a non-existent group.
META_ESCAPE is used for escapes such as \d that match a character. It has an
ESC_xxx value as its data. For ESC_P and ESC_p, the next element contains the
16-bit type and data property values, packed together. Escape sequences such as
\g and \k are turned into other items like META_RECURSE or META_BACKREF and
their ESC_xxx values never occur with META_ESCAPE.
The following have one data item that follows in the next vector element:
META_BIGVALUE Next is a literal >= META_END
META_POSIX POSIX class item (data identifies the class)
META_POSIX_NEG negative POSIX class item (ditto)
The following are followed by a length element, then a number of character code
values (which should match with the length):
META_MARK (*MARK:xxxx)
META_COMMIT_ARG )*COMMIT:xxxx)
META_PRUNE_ARG (*PRUNE:xxx)
META_SKIP_ARG (*SKIP:xxxx)
META_THEN_ARG (*THEN:xxxx)
The following are followed by a length element, then an offset in the pattern
that identifies the name:
META_COND_NAME (?(<name>) or (?('name') or (?(name)
META_COND_RNAME (?(R&name)
META_COND_RNUMBER (?(Rdigits)
META_RECURSE_BYNAME (?&name)
META_BACKREF_BYNAME \k'name' or \k<name> or \k{name} or \g{name}
META_SCS_NAME (*scs:(<name>)...)
META_COND_RNUMBER is used for names that start with R and continue with digits,
because this is an ambiguous case. It could be a back reference to a group with
that name, or it could be a recursion test on a numbered group.
These are followed by an offset, for use in error messages, then a number:
META_COND_NUMBER (?([+-]digits)
META_SCS_NUMBER (*scs:(digits)...)
The following is followed just by an offset, for use in error messages:
META_COND_DEFINE (?(DEFINE)
The following are at first also followed just by an offset for use in error
messages. After the lengths of the branches of a lookbehind group have been
checked the error offset is no longer needed. The lower 16 bits of the main
word are now set to the maximum length of the first branch of the lookbehind
group, and the second word is set to the minimum matching length for a
variable-length lookbehind group, or to LOOKBEHIND_MAX for a group whose
branches are all of fixed length. These values are used when generating
OP_REVERSE or OP_VREVERSE for the first branch. The miminum value is also used
for any subsequent branches because there is only room for one value (the
branch maximum length) in a META_ALT item.
META_LOOKBEHIND (?<= start of lookbehind
META_LOOKBEHIND_NA (*naplb: start of non-atomic lookbehind
META_LOOKBEHINDNOT (?<! start of negative lookbehind
The following are followed by two elements, the minimum and maximum. The
maximum value is limited to 65535 (MAX_REPEAT_COUNT). A maximum value of
"unlimited" is represented by REPEAT_UNLIMITED, which is bigger than it:
META_MINMAX {n,m} repeat
META_MINMAX_PLUS {n,m}+ repeat
META_MINMAX_QUERY {n,m}? repeat
This one is followed by two elements, giving the new option settings for the
main and extra options, respectively.
META_OPTIONS (?i) and friends
This one is followed by three elements. The first is 0 for '>' and 1 for '>=';
the next two are the major and minor numbers:
META_COND_VERSION (?(VERSION<op>x.y)
Callouts are converted into one of two items:
META_CALLOUT_NUMBER (?C with numerical argument
META_CALLOUT_STRING (?C with string argument
In both cases, the next two elements contain the offset and length of the next
item in the pattern. Then there is either one callout number, or a length and
an offset for the string argument. The length includes both delimiters.
Traditional matching function
-----------------------------
The "traditional", and original, matching function is called pcre2_match(), and
it implements an NFA algorithm, similar to the original Henry Spencer algorithm
and the way that Perl works. This is not surprising, since it is intended to be
as compatible with Perl as possible. This is the function most users of PCRE2
will use most of the time. If PCRE2 is compiled with just-in-time (JIT)
support, and studying a compiled pattern with JIT is successful, the JIT code
is run instead of the normal pcre2_match() code, but the result is the same.
The interpreter used to implement backtracking by means of recursive function
calls, but this gave rise to regular complaints when patterns with large search
trees ran out of stack. There was for a while a fudge that used the heap
instead, but this was inefficient and slow. In 2017 I re-wrote pcre2_match() as
a single, non-recursive function that implements backtracking via a vector of
"frames" on the heap, each frame representing a backtracking point. As well as
standard information such as the position in the pattern and position in the
subject, each frame has a number of unassigned variables that can be used
locally to preserve values at a backtracking point. C macros are used
extensively to implement all of this.
Supplementary matching function
-------------------------------
There is a supplementary matching function called pcre2_dfa_match() that
implements a DFA matching algorithm that searches simultaneously for all
possible matches that start at one point in the subject string. (Going back to
my roots: see Historical Note 1 above.) This function intreprets the same
compiled pattern data as pcre2_match(); however, not all the facilities are
available, and those that are do not always work in quite the same way. In
particular, capturing parentheses and backreferences are not supported. See the
user documentation for details.
The algorithm that is used for pcre2_dfa_match() is not a traditional FSM,
because it may have a number of states active at one time. More work would be
needed at compile time to produce a traditional FSM where only one state is
ever active at once. I believe some other regex matchers work this way. JIT
support is not available for this kind of matching.
Changeable options
------------------
The /i, /m, or /s options (PCRE2_CASELESS, PCRE2_MULTILINE, PCRE2_DOTALL) and
some others may be changed in the middle of patterns by items such as (?i).
Their processing is handled entirely at compile time by generating different
opcodes for the different settings. Some options are copied into the opcode's
data, for opcodes such as OP_REFI which depends on the (?r)
(PCRE2_EXTRA_CASELESS_RESTRICT) option. The runtime functions do not need to
keep track of an option's state.
PCRE2_DUPNAMES, PCRE2_EXTENDED, PCRE2_EXTENDED_MORE, and PCRE2_NO_AUTO_CAPTURE
are tracked and processed during the parsing pre-pass. The others are handled
from META_OPTIONS items during the main compile phase.
Format of compiled patterns
---------------------------
The compiled form of a pattern is a vector of unsigned code units (bytes in
8-bit mode, shorts in 16-bit mode, 32-bit words in 32-bit mode), containing
items of variable length. The first code unit in an item contains an opcode,
and the length of the item is either implicit in the opcode or contained in the
data that follows it.
In many cases listed below, LINK_SIZE data values are specified for offsets
within the compiled pattern. LINK_SIZE always specifies a number of bytes. The
default value for LINK_SIZE is 2, except for the 32-bit library, where it can
only be 4. The 8-bit library can be compiled to use 3-byte or 4-byte values,
and the 16-bit library can be compiled to use 4-byte values, though this
impairs performance. Specifying a LINK_SIZE larger than 2 for these libraries
is necessary only when patterns whose compiled length is greater than 65535
code units are going to be processed. When a LINK_SIZE value uses more than one
code unit, the most significant unit is first.
In this description, we assume the "normal" compilation options. Data values
that are counts (e.g. quantifiers) are always two bytes long in 8-bit mode
(most significant byte first), and one code unit in 16-bit and 32-bit modes.
Opcodes with no following data
------------------------------
These items are all just one code unit long:
OP_END end of pattern
OP_ANY match any one character other than newline
OP_ALLANY match any one character, including newline
OP_ANYBYTE match any single code unit, even in UTF-8/16 mode
OP_SOD match start of data: \A
OP_SOM, start of match (subject + offset): \G
OP_SET_SOM, set start of match (\K)
OP_CIRC ^ (start of data)
OP_CIRCM ^ multiline mode (start of data or after newline)
OP_NOT_WORD_BOUNDARY \W
OP_WORD_BOUNDARY \w
OP_NOT_DIGIT \D
OP_DIGIT \d
OP_NOT_HSPACE \H
OP_HSPACE \h
OP_NOT_WHITESPACE \S
OP_WHITESPACE \s
OP_NOT_VSPACE \V
OP_VSPACE \v
OP_NOT_WORDCHAR \W
OP_WORDCHAR \w
OP_EODN match end of data or newline at end: \Z
OP_EOD match end of data: \z
OP_DOLL $ (end of data, or before final newline)
OP_DOLLM $ multiline mode (end of data or before newline)
OP_EXTUNI match an extended Unicode grapheme cluster
OP_ANYNL match any Unicode newline sequence
OP_ASSERT_ACCEPT )
OP_ACCEPT ) These are Perl 5.10's "backtracking control
OP_COMMIT ) verbs". If OP_ACCEPT is inside capturing
OP_FAIL ) parentheses, it may be preceded by one or more
OP_PRUNE ) OP_CLOSE, each followed by a number that
OP_SKIP ) indicates which parentheses must be closed.
OP_THEN )
OP_ASSERT_ACCEPT is used when (*ACCEPT) is encountered within an assertion.
This ends the assertion, not the entire pattern match. The assertion (?!) is
always optimized to OP_FAIL.
OP_ALLANY is used for '.' when PCRE2_DOTALL is set. It is also used for \C in
non-UTF modes and in UTF-32 mode (since one code unit still equals one
character). Another use is for [^] when empty classes are permitted
(PCRE2_ALLOW_EMPTY_CLASS is set).
Backtracking control verbs
--------------------------
Verbs with no arguments generate opcodes with no following data (as listed
in the section above).
(*MARK:NAME) generates OP_MARK followed by the mark name, preceded by a
length in one code unit, and followed by a binary zero. The name length is
limited by the size of the code unit.
(*ACCEPT:NAME) and (*FAIL:NAME) are compiled as (*MARK:NAME)(*ACCEPT) and
(*MARK:NAME)(*FAIL) respectively.
For (*COMMIT:NAME), (*PRUNE:NAME), (*SKIP:NAME), and (*THEN:NAME), the opcodes
OP_COMMIT_ARG, OP_PRUNE_ARG, OP_SKIP_ARG, and OP_THEN_ARG are used, with the
name following in the same format as for OP_MARK.
Matching literal characters
---------------------------
The OP_CHAR opcode is followed by a single character that is to be matched
casefully. For caseless matching of characters that have at most two
case-equivalent code points, OP_CHARI is used. In UTF-8 or UTF-16 modes, the
character may be more than one code unit long. In UTF-32 mode, characters are
always exactly one code unit long.
If there is only one character in a character class, OP_CHAR or OP_CHARI is
used for a positive class, and OP_NOT or OP_NOTI for a negative one (that is,
for something like [^a]).
Caseless matching (positive or negative) of characters that have more than two
case-equivalent code points (which is possible only in UTF mode) is handled by
compiling a Unicode property item (see below), with the pseudo-property
PT_CLIST. The value of this property is an offset in a vector called
"ucd_caseless_sets" which identifies the start of a short list of case
equivalent characters, terminated by the value NOTACHAR (0xffffffff).
Repeating single characters
---------------------------
The common repeats (*, +, ?), when applied to a single character, use the
following opcodes, which come in caseful and caseless versions:
Caseful Caseless
OP_STAR OP_STARI
OP_MINSTAR OP_MINSTARI
OP_POSSTAR OP_POSSTARI
OP_PLUS OP_PLUSI
OP_MINPLUS OP_MINPLUSI
OP_POSPLUS OP_POSPLUSI
OP_QUERY OP_QUERYI
OP_MINQUERY OP_MINQUERYI
OP_POSQUERY OP_POSQUERYI
Each opcode is followed by the character that is to be repeated. In ASCII or
UTF-32 modes, these are two-code-unit items; in UTF-8 or UTF-16 modes, the
length is variable. Those with "MIN" in their names are the minimizing
versions. Those with "POS" in their names are possessive versions. Other kinds
of repeat make use of these opcodes:
Caseful Caseless
OP_UPTO OP_UPTOI
OP_MINUPTO OP_MINUPTOI
OP_POSUPTO OP_POSUPTOI
OP_EXACT OP_EXACTI
Each of these is followed by a count and then the repeated character. The count
is two bytes long in 8-bit mode (most significant byte first), or one code unit
in 16-bit and 32-bit modes.
OP_UPTO matches from 0 to the given number. A repeat with a non-zero minimum
and a fixed maximum is coded as an OP_EXACT followed by an OP_UPTO (or
OP_MINUPTO or OPT_POSUPTO).
Another set of matching repeating opcodes (called OP_NOTSTAR, OP_NOTSTARI,
etc.) are used for repeated, negated, single-character classes such as [^a]*.
The normal single-character opcodes (OP_STAR, etc.) are used for repeated
positive single-character classes.
Repeating character types
-------------------------
Repeats of things like \d are done exactly as for single characters, except
that instead of a character, the opcode for the type (e.g. OP_DIGIT) is stored
in the next code unit. The opcodes are:
OP_TYPESTAR
OP_TYPEMINSTAR
OP_TYPEPOSSTAR
OP_TYPEPLUS
OP_TYPEMINPLUS
OP_TYPEPOSPLUS
OP_TYPEQUERY
OP_TYPEMINQUERY
OP_TYPEPOSQUERY
OP_TYPEUPTO
OP_TYPEMINUPTO
OP_TYPEPOSUPTO
OP_TYPEEXACT
Match by Unicode property
-------------------------
OP_PROP and OP_NOTPROP are used for positive and negative matches of a
character by testing its Unicode property (the \p and \P escape sequences).
Each is followed by two code units that encode the desired property as a type
and a value. The types are a set of #defines of the form PT_xxx, and the values
are enumerations of the form ucp_xx, defined in the pcre2_ucp.h source file.
The value is relevant only for PT_GC (General Category), PT_PC (Particular
Category), PT_SC (Script), PT_BIDICL (Bidi Class), PT_BOOL (Boolean property),
and the pseudo-property PT_CLIST, which is used to identify a list of
case-equivalent characters when there are three or more (see above).
Repeats of these items use the OP_TYPESTAR etc. set of opcodes, followed by
three code units: OP_PROP or OP_NOTPROP, and then the desired property type and
value.
Character classes
-----------------
If there is only one character in a class, OP_CHAR or OP_CHARI is used for a
positive class, and OP_NOT or OP_NOTI for a negative one (that is, for
something like [^a]), except when caselessly matching a character that has more
than two case-equivalent code points (which can happen only in UTF mode). In
this case a Unicode property item is used, as described above in "Matching
literal characters".
A set of repeating opcodes (called OP_NOTSTAR etc.) are used for repeated,
negated, single-character classes. The normal single-character opcodes
(OP_STAR, etc.) are used for repeated positive single-character classes.
When there is more than one character in a class, and all the code points are
less than 256, OP_CLASS is used for a positive class, and OP_NCLASS for a
negative one. In either case, the opcode is followed by a 32-byte (16-short,
8-word) bit map containing a 1 bit for every character that is acceptable. The
bits are counted from the least significant end of each unit. In caseless mode,
bits for both cases are set.
The reason for having both OP_CLASS and OP_NCLASS is so that, in UTF-8 and
16-bit and 32-bit modes, subject characters with values greater than 255 can be
handled correctly. For OP_CLASS they do not match, whereas for OP_NCLASS they
do.
For classes containing characters with values greater than 255 or that contain
\p or \P, OP_XCLASS is used. It optionally uses a bit map if any acceptable
code points are less than 256. After the bit map, the properties of the
character class are listed, if they are present. The items in the list
follows the declaration order of the pattern string. The property list
is followed by single characters and/or character ranges, if they are
present. The characters/ranges are sorted in ascending order, and at
least one non-matching character must be present between any two of
them. In caseless mode, all equivalent characters are explicitly listed.
OP_XCLASS is followed by a LINK_SIZE value containing the total length of the
opcode and its data. This is followed by a code unit containing flag bits:
XCL_NOT indicates that this is a negative class, and XCL_MAP indicates that a
bit map is present. There follows the bit map, if XCL_MAP is set, and then a
sequence of items coded as follows:
XCL_END marks the end of the list
XCL_SINGLE one character follows
XCL_RANGE two characters follow
XCL_PROP a Unicode property (type, value) follows
XCL_NOTPROP a Unicode property (type, value) follows
If a range starts with a code point less than 256 and ends with one greater
than 255, it is split into two ranges, with characters less than 256 being
indicated in the bit map, and the rest with XCL_RANGE.
When XCL_NOT is set, the bit map, if present, contains bits for characters that
are allowed (exactly as for OP_NCLASS), but the list of items that follow it
specifies characters and properties that are not allowed.
The meaning of the bitmap indicated by XCL_MAP is that, if one is present, then
it fully describes which code points < 256 match the class (without needing to
invert the check according to XCL_NOT); the other items in the OP_XCLASS need
not be consulted. However, if a bitmap is not present, then code points < 256
may still match, so the other items in the OP_XCLASS must be consulted.
For classes containing logical expressions, such as "[\p{Greek} && \p{Lu}]" for
"uppercase Greek letters", OP_ECLASS is used. The expression is encoded as a a
stack-based series of operands and operators, in Reverse Polish Notation. Like
an OP_XCLASS, the OP_ECLASS is first followed by a LINK_SIZE value containing
the total length of the opcode and its data. That is followed by a code unit
containing flags: currently just ECL_MAP indicating that a bit map is present.
There follows the bit map, if ECL_MAP is set. Finally, there is a sequence of
items that are either an operand or operator. Each item starts with a single
code unit containing its type:
ECL_AND AND; no additional data
ECL_OR OR; no additional data
ECL_XOR XOR; no additional data
ECL_NOT NOT; no additional data
ECL_XCLASS The additional data which follows ECL_XCLASS is the same as for
an OP_XCLASS, except that this data is preceded by ECL_XCLASS
rather than OP_XCLASS.
Because the OP_ECLASS has its own bitmap (if required), an
ECL_XCLASS should not contain a bitmap.
Additionally, there are two intermediate values used during compilation, but
these are folded away during generation of the opcode, and so never appear
inside an OP_ECLASS at match time. They are:
ECL_ANY match all characters; no additional data
ECL_NONE match no characters; no additional data
The meaning of the bitmap indicated by ECL_MAP is the same as XCL_MAP.
If the bitmap is present, all codepoints < 256 are checked against the bitmap.
Back references
---------------
OP_REF (caseful) or OP_REFI (caseless) is followed by a count containing the
reference number when the reference is to a unique capturing group (either by
number or by name). When named groups are used, there may be more than one
group with the same name. In this case, a reference to such a group by name
generates OP_DNREF or OP_DNREFI. These are followed by two counts: the index
(not the byte offset) in the group name table of the first entry for the
required name, followed by the number of groups with the same name. The
matching code can then search for the first one that is set.
OP_REFI and OP_DNREFI are further followed by an item containing any
case-insensitivity flags.
Repeating character classes and back references
-----------------------------------------------
Single-character classes are handled specially (see above). This section
applies to other classes and also to back references. In both cases, the repeat
information follows the base item. The matching code looks at the following
opcode to see if it is one of these:
OP_CRSTAR
OP_CRMINSTAR
OP_CRPOSSTAR
OP_CRPLUS
OP_CRMINPLUS
OP_CRPOSPLUS
OP_CRQUERY
OP_CRMINQUERY
OP_CRPOSQUERY
OP_CRRANGE
OP_CRMINRANGE
OP_CRPOSRANGE
All but the last three are single-code-unit items, with no data. The range
opcodes are followed by the minimum and maximum repeat counts.
Brackets and alternation
------------------------
A pair of non-capturing round brackets is wrapped round each expression at
compile time, so alternation always happens in the context of brackets.
[Note for North Americans: "bracket" to some English speakers, including
myself, can be round, square, curly, or pointy. Hence this usage rather than
"parentheses".]
Non-capturing brackets use the opcode OP_BRA, capturing brackets use OP_CBRA. A
bracket opcode is followed by a LINK_SIZE value which gives the offset to the
next alternative OP_ALT or, if there aren't any branches, to the terminating
opcode. Each OP_ALT is followed by a LINK_SIZE value giving the offset to the
next one, or to the final opcode. For capturing brackets, the bracket number is
a count that immediately follows the offset.
There are several opcodes that mark the end of a subpattern group. OP_KET is
used for subpatterns that do not repeat indefinitely, OP_KETRMIN and
OP_KETRMAX are used for indefinite repetitions, minimally or maximally
respectively, and OP_KETRPOS for possessive repetitions (see below for more
details). All four are followed by a LINK_SIZE value giving (as a positive
number) the offset back to the matching opening bracket opcode.
If a subpattern is quantified such that it is permitted to match zero times, it
is preceded by one of OP_BRAZERO, OP_BRAMINZERO, or OP_SKIPZERO. These are
single-unit opcodes that tell the matcher that skipping the following
subpattern entirely is a valid match. In the case of the first two, not
skipping the pattern is also valid (greedy and non-greedy). The third is used
when a pattern has the quantifier {0,0}. It cannot be entirely discarded,
because it may be called as a subroutine from elsewhere in the pattern.
A subpattern with an indefinite maximum repetition is replicated in the
compiled data its minimum number of times (or once with OP_BRAZERO if the
minimum is zero), with the final copy terminating with OP_KETRMIN or OP_KETRMAX
as appropriate.
A subpattern with a bounded maximum repetition is replicated in a nested
fashion up to the maximum number of times, with OP_BRAZERO or OP_BRAMINZERO
before each replication after the minimum, so that, for example, (abc){2,5} is
compiled as (abc)(abc)((abc)((abc)(abc)?)?)?, except that each bracketed group
has the same number.
When a repeated subpattern has an unbounded upper limit, it is checked to see
whether it could match an empty string. If this is the case, the opcode in the
final replication is changed to OP_SBRA or OP_SCBRA. This tells the matcher
that it needs to check for matching an empty string when it hits OP_KETRMIN or
OP_KETRMAX, and if so, to break the loop.
Possessive brackets
-------------------
When a repeated group (capturing or non-capturing) is marked as possessive by
the "+" notation, e.g. (abc)++, different opcodes are used. Their names all
have POS on the end, e.g. OP_BRAPOS instead of OP_BRA and OP_SCBRAPOS instead
of OP_SCBRA. The end of such a group is marked by OP_KETRPOS. If the minimum
repetition is zero, the group is preceded by OP_BRAPOSZERO.
Once-only (atomic) groups
-------------------------
These are just like other subpatterns, but they start with the opcode OP_ONCE.
The check for matching an empty string in an unbounded repeat is handled
entirely at runtime, so there is just this one opcode for atomic groups.
Assertions
----------
Forward assertions are also just like other subpatterns, but starting with one
of the opcodes OP_ASSERT, OP_ASSERT_NA (non-atomic assertion), or
OP_ASSERT_NOT.
Backward assertions use the opcodes OP_ASSERTBACK, OP_ASSERTBACK_NA, and
OP_ASSERTBACK_NOT. If all the branches of a backward assertion are of fixed
length (not necessarily the same), the first opcode inside each branch is
OP_REVERSE, followed by an IMM2_SIZE count of the number of characters to move
back the pointer in the subject string, thus allowing each branch to have a
different (but fixed) length.
Variable-length backward assertions whose maximum matching length is limited
are also supported. For such assertions, the first opcode inside each branch is
OP_VREVERSE, followed by the minimum and maximum lengths for that branch,
unless these happen to be equal, in which case OP_REVERSE is used. These
IMM2_SIZE values occupy two code units each in 8-bit mode, and 1 code unit in
16/32 bit modes.
In ASCII or UTF-32 mode, the character counts in OP_REVERSE and OP_VREVERSE are
also the number of code units, but in UTF-8/16 mode each character may occupy
more than one code unit.
The "scan substring" assertion compiles as OP_ASSERT_SCS. This opcode is
followed by a list of arguments. Each argument is either an OP_CREF or
OP_DNCREF byte code sequence. The details of these sequences are described
in the next section.
For example (*scs:(1,'NAME')...PATTERN...) is translated to:
[OP_ASSERT_SCS] [OP_CREF] [OP_CREF] ...PATTERN... [OP_KET]
If 'NAME' is a duplicated name, the second [OP_CREF] is [OP_DNCREF] instead.
Conditional subpatterns
-----------------------
These are like other subpatterns, but they start with the opcode OP_COND, or
OP_SCOND for one that might match an empty string in an unbounded repeat.
If the condition is a back reference, this is stored at the start of the
subpattern using the opcode OP_CREF followed by a count containing the
reference number, provided that the reference is to a unique capturing group.
If the reference was by name and there is more than one group with that name,
OP_DNCREF is used instead. It is followed by two counts: the index in the group
names table, and the number of groups with the same name. The allows the
matcher to check if any group with the given name is set.
If the condition is "in recursion" (coded as "(?(R)"), or "in recursion of
group x" (coded as "(?(Rx)"), the group number is stored at the start of the
subpattern using the opcode OP_RREF (with a value of RREF_ANY (0xffff) for "the
whole pattern") or OP_DNRREF (with data as for OP_DNCREF).
For a DEFINE condition, OP_FALSE is used (with no associated data). During
compilation, however, a DEFINE condition is coded as OP_DEFINE so that, when
the conditional group is complete, there can be a check to ensure that it
contains only one top-level branch. Once this has happened, the opcode is
changed to OP_FALSE, so the matcher never sees OP_DEFINE.
There is a special PCRE2-specific condition of the form (VERSION[>]=x.y), which
tests the PCRE2 version number. This compiles into one of the opcodes OP_TRUE
or OP_FALSE.
If a condition is not a back reference, recursion test, DEFINE, or VERSION, it
must start with a parenthesized atomic assertion, whose opcode normally
immediately follows OP_COND or OP_SCOND. However, if automatic callouts are
enabled, a callout is inserted immediately before the assertion. It is also
possible to insert a manual callout at this point. Only assertion conditions
may have callouts preceding the condition.
A condition that is the negative assertion (?!) is optimized to OP_FAIL in all
parts of the pattern, so this is another opcode that may appear as a condition.
It is treated the same as OP_FALSE.
Recursion
---------
Recursion either matches the current pattern, or some subexpression. The opcode
OP_RECURSE is followed by a LINK_SIZE value that is the offset to the starting
bracket from the start of the whole pattern. OP_RECURSE is also used for
"subroutine" calls, even though they are not strictly a recursion. Up till
release 10.30 recursions were treated as atomic groups, making them
incompatible with Perl (but PCRE had them well before Perl did). From 10.30,
backtracking into recursions is supported.
Repeated recursions used to be wrapped inside OP_ONCE brackets, which not only
forced no backtracking, but also allowed repetition to be handled as for other
bracketed groups. From 10.30 onwards, repeated recursions are duplicated for
their minimum repetitions, and then wrapped in non-capturing brackets for the
remainder. For example, (?1){3} is treated as (?1)(?1)(?1), and (?1){2,4} is
treated as (?1)(?1)(?:(?1)){0,2}.
Callouts
--------
A callout may have either a numerical argument or a string argument. These use
OP_CALLOUT or OP_CALLOUT_STR, respectively. In each case these are followed by
two LINK_SIZE values giving the offset in the pattern string to the start of
the following item, and another count giving the length of this item. These
values make it possible for pcre2test to output useful tracing information
using callouts.
In the case of a numeric callout, after these two values there is a single code
unit containing the callout number, in the range 0-255, with 255 being used for
callouts that are automatically inserted as a result of the PCRE2_AUTO_CALLOUT
option. Thus, this opcode item is of fixed length:
[OP_CALLOUT] [PATTERN_OFFSET] [PATTERN_LENGTH] [NUMBER]
For callouts with string arguments, OP_CALLOUT_STR has three more data items:
a LINK_SIZE value giving the complete length of the entire opcode item, a
LINK_SIZE item containing the offset within the pattern string to the start of
the string argument, and the string itself, preceded by its starting delimiter
and followed by a binary zero. When a callout function is called, a pointer to
the actual string is passed, but the delimiter can be accessed as string[-1] if
the application needs it. In the 8-bit library, the callout in /X(?C'abc')Y/ is
compiled as the following bytes (decimal numbers represent binary values):
[OP_CALLOUT_STR] [0] [10] [0] [1] [0] [14] [0] [5] ['] [a] [b] [c] [0]
-------- ------- -------- -------
| | | |
------- LINK_SIZE items ------
Opcode table checking
---------------------
The last opcode that is defined in pcre2_internal.h is OP_TABLE_LENGTH. This is
not a real opcode, but is used to check at compile time that tables indexed by
opcode are the correct length, in order to catch updating errors.

Installation Instructions
*************************
Copyright (C) 1994-1996, 1999-2002, 2004-2017, 2020-2021 Free

notice and this notice are preserved. This file is offered as-is,
without warranty of any kind.
Basic Installation
==================
Briefly, the shell command './configure && make && make install'
should configure, build, and install this package. The following
more-detailed instructions are generic; see the 'README' file for
instructions specific to this package. Some packages provide this
'INSTALL' file but do not implement all of the features documented
below. The lack of an optional feature in a given package is not
necessarily a bug. More recommendations for GNU packages can be found
in *note Makefile Conventions: (standards)Makefile Conventions.
The 'configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a 'Makefile' in each directory of the package.
It may also create one or more '.h' files containing system-dependent
definitions. Finally, it creates a shell script 'config.status' that
you can run in the future to recreate the current configuration, and a
file 'config.log' containing compiler output (useful mainly for
debugging 'configure').
It can also use an optional file (typically called 'config.cache' and
enabled with '--cache-file=config.cache' or simply '-C') that saves the
results of its tests to speed up reconfiguring. Caching is disabled by
default to prevent problems with accidental use of stale cache files.
If you need to do unusual things to compile the package, please try
to figure out how 'configure' could check whether to do them, and mail
diffs or instructions to the address given in the 'README' so they can
be considered for the next release. If you are using the cache, and at
some point 'config.cache' contains results you don't want to keep, you
may remove or edit it.
The file 'configure.ac' (or 'configure.in') is used to create
'configure' by a program called 'autoconf'. You need 'configure.ac' if
you want to change it or regenerate 'configure' using a newer version of
'autoconf'.
The simplest way to compile this package is:
1. 'cd' to the directory containing the package's source code and type
'./configure' to configure the package for your system.
Running 'configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type 'make' to compile the package.
3. Optionally, type 'make check' to run any self-tests that come with
the package, generally using the just-built uninstalled binaries.
4. Type 'make install' to install the programs and any data files and
documentation. When installing into a prefix owned by root, it is
recommended that the package be configured and built as a regular
user, and only the 'make install' phase executed with root
privileges.
5. Optionally, type 'make installcheck' to repeat any self-tests, but
this time using the binaries in their final installed location.
This target does not install anything. Running this target as a
regular user, particularly if the prior 'make install' required
root privileges, verifies that the installation completed
correctly.
6. You can remove the program binaries and object files from the
source code directory by typing 'make clean'. To also remove the
files that 'configure' created (so you can compile the package for
a different kind of computer), type 'make distclean'. There is
also a 'make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
7. Often, you can also type 'make uninstall' to remove the installed
files again. In practice, not all packages have tested that
uninstallation works correctly, even though it is required by the
GNU Coding Standards.
8. Some packages, particularly those that use Automake, provide 'make
distcheck', which can by used by developers to test that all other
targets like 'make install' and 'make uninstall' work correctly.
This target is generally not run by end users.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the 'configure' script does not know about. Run './configure --help'
for details on some of the pertinent environment variables.
You can give 'configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here is
an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU 'make'. 'cd' to the
directory where you want the object files and executables to go and run
the 'configure' script. 'configure' automatically checks for the source
code in the directory that 'configure' is in and in '..'. This is known
as a "VPATH" build.
With a non-GNU 'make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use 'make distclean' before
reconfiguring for another architecture.
On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple '-arch' options to the
compiler but only a single '-arch' option to the preprocessor. Like
this:
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CPP="gcc -E" CXXCPP="g++ -E"
This is not guaranteed to produce working output in all cases, you
may have to build one architecture at a time and combine the results
using the 'lipo' tool if you have problems.
Installation Names
==================
By default, 'make install' installs the package's commands under
'/usr/local/bin', include files under '/usr/local/include', etc. You
can specify an installation prefix other than '/usr/local' by giving
'configure' the option '--prefix=PREFIX', where PREFIX must be an
absolute file name.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like '--bindir=DIR' to specify different values for particular
kinds of files. Run 'configure --help' for a list of the directories
you can set and what kinds of files go in them. In general, the default
for these options is expressed in terms of '${prefix}', so that
specifying just '--prefix' will affect all of the other directory
specifications that were not explicitly provided.
The most portable way to affect installation locations is to pass the
correct locations to 'configure'; however, many packages provide one or
both of the following shortcuts of passing variable assignments to the
'make install' command line to change installation locations without
having to reconfigure or recompile.
The first method involves providing an override variable for each
affected directory. For example, 'make install
prefix=/alternate/directory' will choose an alternate location for all
directory configuration variables that were expressed in terms of
'${prefix}'. Any directories that were specified during 'configure',
but not in terms of '${prefix}', must each be overridden at install time
for the entire installation to be relocated. The approach of makefile
variable overrides for each directory variable is required by the GNU
Coding Standards, and ideally causes no recompilation. However, some
platforms have known limitations with the semantics of shared libraries
that end up requiring recompilation when using this method, particularly
noticeable in packages that use GNU Libtool.
The second method involves providing the 'DESTDIR' variable. For
example, 'make install DESTDIR=/alternate/directory' will prepend
'/alternate/directory' before all installation names. The approach of
'DESTDIR' overrides is not required by the GNU Coding Standards, and
does not work on platforms that have drive letters. On the other hand,
it does better at avoiding recompilation issues, and works well even
when some directory options were not specified in terms of '${prefix}'
at 'configure' time.
Optional Features
=================
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving 'configure' the
option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
Some packages pay attention to '--enable-FEATURE' options to
'configure', where FEATURE indicates an optional part of the package.
They may also pay attention to '--with-PACKAGE' options, where PACKAGE
is something like 'gnu-as' or 'x' (for the X Window System). The
'README' should mention any '--enable-' and '--with-' options that the
package recognizes.
For packages that use the X Window System, 'configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the 'configure' options '--x-includes=DIR' and
'--x-libraries=DIR' to specify their locations.
Some packages offer the ability to configure how verbose the
execution of 'make' will be. For these packages, running './configure
--enable-silent-rules' sets the default to minimal output, which can be
overridden with 'make V=1'; while running './configure
--disable-silent-rules' sets the default to verbose, which can be
overridden with 'make V=0'.
Particular systems
==================
On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC
is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
HP-UX 'make' updates targets which have the same timestamps as their
prerequisites, which makes it generally unusable when shipped generated
files such as 'configure' are involved. Use GNU 'make' instead.
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its '<wchar.h>' header file. The option '-nodtk' can be used as a
workaround. If GNU CC is not installed, it is therefore recommended to
try
./configure CC="cc"
and if that doesn't work, try
./configure CC="cc -nodtk"
On Solaris, don't put '/usr/ucb' early in your 'PATH'. This
directory contains several dysfunctional programs; working variants of
these programs are available in '/usr/bin'. So, if you need '/usr/ucb'
in your 'PATH', put it _after_ '/usr/bin'.
On Haiku, software installed for all users goes in '/boot/common',
not '/usr/local'. It is recommended to use the following options:
./configure --prefix=/boot/common
Specifying the System Type
==========================
There may be some features 'configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, 'configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
'--build=TYPE' option. TYPE can either be a short name for the system
type, such as 'sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS
KERNEL-OS
See the file 'config.sub' for the possible values of each field. If
'config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option '--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with '--host=TYPE'.
Sharing Defaults
================
If you want to set default values for 'configure' scripts to share,
you can create a site shell script called 'config.site' that gives
default values for variables like 'CC', 'cache_file', and 'prefix'.
'configure' looks for 'PREFIX/share/config.site' if it exists, then
'PREFIX/etc/config.site' if it exists. Or, you can set the
'CONFIG_SITE' environment variable to the location of the site script.
A warning: not all 'configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to 'configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the 'configure' command line, using 'VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified 'gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
Autoconf limitation. Until the limitation is lifted, you can use this
workaround:
CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
'configure' Invocation
======================
'configure' recognizes the following options to control how it
operates.
'--help'
'-h'
Print a summary of all of the options to 'configure', and exit.
'--help=short'
'--help=recursive'
Print a summary of the options unique to this package's
'configure', and exit. The 'short' variant lists options used only
in the top level, while the 'recursive' variant lists options also
present in any nested packages.
'--version'
'-V'
Print the version of Autoconf used to generate the 'configure'
script, and exit.
'--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally 'config.cache'. FILE defaults to '/dev/null' to
disable caching.
'--config-cache'
'-C'
Alias for '--cache-file=config.cache'.
'--quiet'
'--silent'
'-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to '/dev/null' (any error
messages will still be shown).
'--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
'configure' can determine that directory automatically.
'--prefix=DIR'
Use DIR as the installation prefix. *note Installation Names:: for
more details, including other options available for fine-tuning the
installation locations.
'--no-create'
'-n'
Run the configure checks, but stop before creating any output
files.
'configure' also accepts some other, not widely useful, options. Run
'configure --help' for more details.

News about PCRE2 releases
-------------------------
Version 10.45 05-February-2025
------------------------------
This is a comparatively large release, incorporating new features, some
bugfixes, and a few changes with slight backwards compatibility implications.
Please see the ChangeLog and Git log for further details.
Only changes to behaviour, changes to the API, and major changes to the pattern
syntax are described here.
This release is the first to be available as a (signed) Git tag, or
alternatively as a (signed) tarball of the Git tag.
This is also the first release to be made by the new maintainers of PCRE2, and
we would like to thank Philip Hazel, creator and maintainer of PCRE and PCRE2.
* (Git change) The sljit project has been split out into a separate Git
repository. Git users must now run `git submodule init; git submodule update`
after a Git checkout.
* (Behaviour change) Update Unicode support to UCD 16.
* (Match behaviour change) Case-insensitive matching of Unicode properties
Ll, Lt, and Lu has been changed to match Perl. Previously, /\p{Ll}/i would
match only lower-case characters (even though case-insensitive matching was
specified). This also affects case-insensitive matching of POSIX classes such
as [:lower:].
* (Minor match behaviour change) Case-insensitive matching of backreferences now
respects the PCRE2_EXTRA_CASELESS_RESTRICT option.
* (Minor pattern syntax change) Parsing of the \x escape is stricter, and is
no longer parsed as an escape for the NUL character if not followed by '{' or
a hexadecimal digit. Use \x00 instead.
* (Major new feature) Add a new feature called scan substring. This is a new
type of assertion which matches the content of a capturing block to a
sub-pattern.
Example: to find a word that contains the rare (in English) sequence of
letters "rh" not at the start:
\b(\w++)(*scan_substring:(1).+rh)
The first group captures a word which is then scanned by the
(*scan_substring:(1) ... ) assertion, which tests whether the pattern ".+rh"
matches the capture group "(1)".
* (Major new feature) Add support for UTS#18 compatible character classes,
using the new option PCRE2_ALT_EXTENDED_CLASS. This adds '[' as a
metacharacter within character classes and the operators '&&', '--' and '~~',
allowing subtractions and intersections of character classes to be easily
expressed.
Example: to match Thai or Greek letters (but not letters or other characters
in those scripts), use [\p{L}&&[\p{Thai}||\p{Greek}]].
* (Major new feature) Add support for Perl-style extended character classes,
using the syntax (?[...]). This also allows expressing subtractions and
intersections of character classes, but using a different syntax to UTS#18.
Example: to match Thai or Greek letters (but not letters or other characters
in those scripts), use (?[\p{L} & (\p{Thai} + \p{Greek})]).
* (Minor feature) Significant improvements to the character class match engine.
Compiled character classes are now more compact, and have faster matching
for large or complex character sets, using binary search through the set.
* JIT compilation now fails with the new error code PCRE2_ERROR_JIT_UNSUPPORTED
for patterns which use features not supported by the JIT compiler.
* (Minor feature) New options PCRE2_EXTRA_NO_BS0 (disallow \0 as an escape for
the NUL character); PCRE2_EXTRA_PYTHON_OCTAL (use Python disambiguation rules
for deciding whether \12 is a backreference or an octal escape);
PCRE2_EXTRA_NEVER_CALLOUT (disable callout syntax entirely);
PCRE2_EXTRA_TURKISH_CASING (use Turkish rules for case-insensitive matching).
* (Minor feature) Add new API function pcre2_set_optimize() for controlling
which optimizations are enabled.
* (Minor new features) A variety of extensions have been made to
pcre2_substitute() and its syntax for replacement strings. These now support:
\123 octal escapes; titlecasing \u\L; \1 backreferences; \g<1> and $<NAME>
backreferences; $& $` $' and $_; new function
pcre2_set_substitute_case_callout() to allow locale-aware case transformation.
Version 10.44 07-June-2024
--------------------------
This is mostly a bug-fix and tidying release. There is one new function, to set
a maximum size for a compiled pattern. The maximum name length for groups is
increased to 128. Some auxiliary files for building under VMS are added.
Version 10.43 16-February-2024
------------------------------
There are quite a lot of changes in this release (see ChangeLog and Git log for
a list). Those that are not bugfixes or code tidies are:
* The JIT code no longer supports ARMv5 architecture.
* A new function pcre2_get_match_data_heapframes_size() for finer heap control.
* New option flags to restrict the interaction between ASCII and non-ASCII
characters for caseless matching and \d and friends. There are also new
pattern constructs to control these flags from within a pattern.
* Upgrade to Unicode 15.0.0.
* Treat a NULL pattern with zero length as an empty string.
* Added support for limited-length variable-length lookbehind assertions, with
a default maximum length of 255 characters (same as Perl) but with a function
to adjust the limit.
* Support for LoongArch in JIT.
* Perl changed the meaning of (for example) {,3} which did not used to be
recognized as a quantifier. Now it means {0,3} and PCRE2 has also changed.
Note that {,} is still not a quantifier.
* Following Perl, allow spaces and tabs after { and before } in all Perl-
compatible items that use braces, and also around commas in quantifiers. The
one exception in PCRE2 is \u{...}, which is from ECMAScript, not Perl, and
PCRE2 follows ECMAScript usage.
* Changed the meaning of \w and its synonyms and derivatives (\b and \B) in UCP
mode to follow Perl. It now matches characters whose general categories are L
or N or whose particular categories are Mn (non-spacing mark) or Pc
(combining punctuation).
* Changed the default meaning of [:xdigit:] in UCP mode to follow Perl. It now
matches the "fullwidth" versions of hex digits. PCRE2_EXTRA_ASCII_DIGIT can
be used to keep it ASCII only.
* Make PCRE2_UCP the default in UTF mode in pcre2grep and add --no-ucp,
--case-restrict and --posix-digit.
* Add --group-separator and --no-group-separator to pcre2grep.
Version 10.42 11-December-2022
------------------------------
This is an unexpectedly early release to fix a problem that was introduced in
10.41. ChangeLog number 19 (GitHub #139) added the default definition of
PCRE2_CALL_CONVENTION to pcre2posix.c instead of pcre2posix.h, which meant that
programs including pcre2posix.h but not pcre2.h couldn't compile. A new test
that checks this case has been added.
A couple of other minor issues are also fixed, and a patch for an intermittent
JIT fault is also included. See ChangeLog and the Git log.
Version 10.41 06-December-2022
------------------------------
This is another mainly bug-fixing and code-tidying release. There is one
significant upgrade to pcre2grep: it now behaves like GNU grep when matching
more than one pattern and a later pattern matches at an earlier point in the
subject when the matched substrings are being identified by colour or by
offsets.
Version 10.40 15-April-2022
---------------------------
This is mostly a bug-fixing and code-tidying release. However, there are some
extensions to Unicode property handling:
* Added support for Bidi_Class and a number of binary Unicode properties,
including Bidi_Control.
* A number of changes to script matching for \p and \P:
(a) Script extensions for a character are now coded as a bitmap instead of
a list of script numbers, which should be faster and does not need a
loop.
(b) Added the syntax \p{script:xxx} and \p{script_extensions:xxx} (synonyms
sc and scx).
(c) Changed \p{scriptname} from being the same as \p{sc:scriptname} to being
the same as \p{scx:scriptname} because this change happened in Perl at
release 5.26.
(d) The standard Unicode 4-letter abbreviations for script names are now
recognized.
(e) In accordance with Unicode and Perl's "loose matching" rules, spaces,
hyphens, and underscores are ignored in property names, which are then
matched independent of case.
As always, see ChangeLog for a list of all changes (also the Git log).
Version 10.39 29-October-2021
-----------------------------
This release is happening soon after 10.38 because the bug fix is important.
1. Fix incorrect detection of alternatives in first character search in JIT.
2. Update to Unicode 14.0.0.
3. Some code cleanups (see ChangeLog).
Version 10.38 01-October-2021
-----------------------------
As well as some bug fixes and tidies (as always, see ChangeLog for details),
the documentation is updated to list the new URLs, following the move of the
source repository to GitHub and the mailing list to Google Groups.
* The CMake build system can now build both static and shared libraries in one
go.
* Following Perl's lead, \K is now locked out in lookaround assertions by
default, but an option is provided to re-enable the previous behaviour.
Version 10.37 26-May-2021
-------------------------
A few more bug fixes and tidies. The only change of real note is the removal of
the actual POSIX names regcomp etc. from the POSIX wrapper library because
these have caused issues for some applications (see 10.33 #2 below).
Version 10.36 04-December-2020
------------------------------
Again, mainly bug fixes and tidies. The only enhancements are the addition of
GNU grep's -m (aka --max-count) option to pcre2grep, and also unifying the
handling of substitution strings for both -O and callouts in pcre2grep, with
the addition of $x{...} and $o{...} to allow for characters whose code points
are greater than 255 in Unicode mode.
NOTE: there is an outstanding issue with JIT support for MacOS on arm64
hardware. For details, please see Bugzilla issue #2618.
Version 10.35 15-April-2020
---------------------------
Bugfixes, tidies, and a few new enhancements.
1. Capturing groups that contain recursive backreferences to themselves are no
longer automatically atomic, because the restriction is no longer necessary
as a result of the 10.30 restructuring.
2. Several new options for pcre2_substitute().
3. When Unicode is supported and PCRE2_UCP is set without PCRE2_UTF, Unicode
character properties are used for upper/lower case computations on characters
whose code points are greater than 127.
4. The character tables (for low-valued characters) can now more easily be
saved and restored in binary.
5. Updated to Unicode 13.0.0.
Version 10.34 21-November-2019
------------------------------
Another release with a few enhancements as well as bugfixes and tidies. The
main new features are:
1. There is now some support for matching in invalid UTF strings.
2. Non-atomic positive lookarounds are implemented in the pcre2_match()
interpreter, but not in JIT.
3. Added two new functions: pcre2_get_match_data_size() and
pcre2_maketables_free().
4. Upgraded to Unicode 12.1.0.
Version 10.33 16-April-2019
---------------------------
Yet more bugfixes, tidies, and a few enhancements, summarized here (see
ChangeLog for the full list):
1. Callouts from pcre2_substitute() are now available.
2. The POSIX functions are now all called pcre2_regcomp() etc., with wrapper
functions that use the standard POSIX names. However, in pcre2posix.h the POSIX
names are defined as macros. This should help avoid linking with the wrong
library in some environments, while still exporting the POSIX names for
pre-existing programs that use them.
3. Some new options:
(a) PCRE2_EXTRA_ESCAPED_CR_IS_LF makes \r behave as \n.
(b) PCRE2_EXTRA_ALT_BSUX enables support for ECMAScript 6's \u{hh...}
construct.
(c) PCRE2_COPY_MATCHED_SUBJECT causes a copy of a matched subject to be
made, instead of just remembering a pointer.
4. Some new Perl features:
(a) Perl 5.28's experimental alphabetic names for atomic groups and
lookaround assertions, for example, (*pla:...) and (*atomic:...).
(b) The new Perl "script run" features (*script_run:...) and
(*atomic_script_run:...) aka (*sr:...) and (*asr:...).
(c) When PCRE2_UTF is set, allow non-ASCII letters and decimal digits in
capture group names.
5. --disable-percent-zt disables the use of %zu and %td in formatting strings
in pcre2test. They were already automatically disabled for VC and older C
compilers.
6. Some changes related to callouts in pcre2grep:
(a) Support for running an external program under VMS has been added, in
addition to Windows and fork() support.
(b) --disable-pcre2grep-callout-fork restricts the callout support in
to the inbuilt echo facility.
Version 10.32 10-September-2018
-------------------------------
This is another mainly bugfix and tidying release with a few minor
enhancements. These are the main ones:
1. pcre2grep now supports the inclusion of binary zeros in patterns that are
read from files via the -f option.
2. ./configure now supports --enable-jit=auto, which automatically enables JIT
if the hardware supports it.
3. In pcre2_dfa_match(), internal recursive calls no longer use the stack for
local workspace and local ovectors. Instead, an initial block of stack is
reserved, but if this is insufficient, heap memory is used. The heap limit
parameter now applies to pcre2_dfa_match().
4. Updated to Unicode version 11.0.0.
5. (*ACCEPT:ARG), (*FAIL:ARG), and (*COMMIT:ARG) are now supported.
6. Added support for \N{U+dddd}, but only in Unicode mode.
7. Added support for (?^) to unset all imnsx options.
Version 10.31 12-February-2018
------------------------------
This is mainly a bugfix and tidying release (see ChangeLog for full details).
However, there are some minor enhancements.
1. New pcre2_config() options: PCRE2_CONFIG_NEVER_BACKSLASH_C and
PCRE2_CONFIG_COMPILED_WIDTHS.
2. New pcre2_pattern_info() option PCRE2_INFO_EXTRAOPTIONS to retrieve the
extra compile time options.
3. There are now public names for all the pcre2_compile() error numbers.
4. Added PCRE2_CALLOUT_STARTMATCH and PCRE2_CALLOUT_BACKTRACK bits to a new
field callout_flags in callout blocks.
Version 10.30 14-August-2017
----------------------------
The full list of changes that includes bugfixes and tidies is, as always, in
ChangeLog. These are the most important new features:
1. The main interpreter, pcre2_match(), has been refactored into a new version
that does not use recursive function calls (and therefore the system stack) for
remembering backtracking positions. This makes --disable-stack-for-recursion a
NOOP. The new implementation allows backtracking into recursive group calls in
patterns, making it more compatible with Perl, and also fixes some other
previously hard-to-do issues. For patterns that have a lot of backtracking, the
heap is now used, and there is an explicit limit on the amount, settable by
pcre2_set_heap_limit() or (*LIMIT_HEAP=xxx). The "recursion limit" is retained,
but is renamed as "depth limit" (though the old names remain for
compatibility).
There is also a change in the way callouts from pcre2_match() are handled. The
offset_vector field in the callout block is no longer a pointer to the
actual ovector that was passed to the matching function in the match data
block. Instead it points to an internal ovector of a size large enough to hold
all possible captured substrings in the pattern.
2. The new option PCRE2_ENDANCHORED insists that a pattern match must end at
the end of the subject.
3. The new option PCRE2_EXTENDED_MORE implements Perl's /xx feature, and
pcre2test is upgraded to support it. Setting within the pattern by (?xx) is
also supported.
4. (?n) can be used to set PCRE2_NO_AUTO_CAPTURE, because Perl now has this.
5. Additional compile options in the compile context are now available, and the
first two are: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES and
PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL.
6. The newline type PCRE2_NEWLINE_NUL is now available.
7. The match limit value now also applies to pcre2_dfa_match() as there are
patterns that can use up a lot of resources without necessarily recursing very
deeply.
8. The option REG_PEND (a GNU extension) is now available for the POSIX
wrapper. Also there is a new option PCRE2_LITERAL which is used to support
REG_NOSPEC.
9. PCRE2_EXTRA_MATCH_LINE and PCRE2_EXTRA_MATCH_WORD are implemented for the
benefit of pcre2grep, and pcre2grep's -F, -w, and -x options are re-implemented
using PCRE2_LITERAL, PCRE2_EXTRA_MATCH_WORD, and PCRE2_EXTRA_MATCH_LINE. This
is tidier and also fixes some bugs.
10. The Unicode tables are upgraded from Unicode 8.0.0 to Unicode 10.0.0.
11. There are some experimental functions for converting foreign patterns
(globs and POSIX patterns) into PCRE2 patterns.
Version 10.23 14-February-2017
------------------------------
1. ChangeLog has the details of a lot of bug fixes and tidies.
2. There has been a major re-factoring of the pcre2_compile.c file. Most syntax
checking is now done in the pre-pass that identifies capturing groups. This has
reduced the amount of duplication and made the code tidier. While doing this,
some minor bugs and Perl incompatibilities were fixed (see ChangeLog for
details.)
3. Back references are now permitted in lookbehind assertions when there are
no duplicated group numbers (that is, (?| has not been used), and, if the
reference is by name, there is only one group of that name. The referenced
group must, of course be of fixed length.
4. \g{+<number>} (e.g. \g{+2} ) is now supported. It is a "forward back
reference" and can be useful in repetitions (compare \g{-<number>} ). Perl does
not recognize this syntax.
5. pcre2grep now automatically expands its buffer up to a maximum set by
--max-buffer-size.
6. The -t option (grand total) has been added to pcre2grep.
7. A new function called pcre2_code_copy_with_tables() exists to copy a
compiled pattern along with a private copy of the character tables that is
uses.
8. A user supplied a number of patches to upgrade pcre2grep under Windows and
tidy the code.
9. Several updates have been made to pcre2test and test scripts (see
ChangeLog).
Version 10.22 29-July-2016
--------------------------
1. ChangeLog has the details of a number of bug fixes.
2. The POSIX wrapper function regcomp() did not used to support back references
and subroutine calls if called with the REG_NOSUB option. It now does.
3. A new function, pcre2_code_copy(), is added, to make a copy of a compiled
pattern.
4. Support for string callouts is added to pcre2grep.
5. Added the PCRE2_NO_JIT option to pcre2_match().
6. The pcre2_get_error_message() function now returns with a negative error
code if the error number it is given is unknown.
7. Several updates have been made to pcre2test and test scripts (see
ChangeLog).
Version 10.21 12-January-2016
-----------------------------
1. Many bugs have been fixed. A large number of them were provoked only by very
strange pattern input, and were discovered by fuzzers. Some others were
discovered by code auditing. See ChangeLog for details.
2. The Unicode tables have been updated to Unicode version 8.0.0.
3. For Perl compatibility in EBCDIC environments, ranges such as a-z in a
class, where both values are literal letters in the same case, omit the
non-letter EBCDIC code points within the range.
4. There have been a number of enhancements to the pcre2_substitute() function,
giving more flexibility to replacement facilities. It is now also possible to
cause the function to return the needed buffer size if the one given is too
small.
5. The PCRE2_ALT_VERBNAMES option causes the "name" parts of special verbs such
as (*THEN:name) to be processed for backslashes and to take note of
PCRE2_EXTENDED.
6. PCRE2_INFO_HASBACKSLASHC makes it possible for a client to find out if a
pattern uses \C, and --never-backslash-C makes it possible to compile a version
PCRE2 in which the use of \C is always forbidden.
7. A limit to the length of pattern that can be handled can now be set by
calling pcre2_set_max_pattern_length().
8. When matching an unanchored pattern, a match can be required to begin within
a given number of code units after the start of the subject by calling
pcre2_set_offset_limit().
9. The pcre2test program has been extended to test new facilities, and it can
now run the tests when LF on its own is not a valid newline sequence.
10. The RunTest script has also been updated to enable more tests to be run.
11. There have been some minor performance enhancements.
Version 10.20 30-June-2015
--------------------------
1. Callouts with string arguments and the pcre2_callout_enumerate() function
have been implemented.
2. The PCRE2_NEVER_BACKSLASH_C option, which locks out the use of \C, is added.
3. The PCRE2_ALT_CIRCUMFLEX option lets ^ match after a newline at the end of a
subject in multiline mode.
4. The way named subpatterns are handled has been refactored. The previous
approach had several bugs.
5. The handling of \c in EBCDIC environments has been changed to conform to the
perlebcdic document. This is an incompatible change.
6. Bugs have been mended, many of them discovered by fuzzers.
Version 10.10 06-March-2015
---------------------------
1. Serialization and de-serialization functions have been added to the API,
making it possible to save and restore sets of compiled patterns, though
restoration must be done in the same environment that was used for compilation.
2. The (*NO_JIT) feature has been added; this makes it possible for a pattern
creator to specify that JIT is not to be used.
3. A number of bugs have been fixed. In particular, bugs that caused building
on Windows using CMake to fail have been mended.
Version 10.00 05-January-2015
-----------------------------
Version 10.00 is the first release of PCRE2, a revised API for the PCRE
library. Changes prior to 10.00 are logged in the ChangeLog file for the old
API, up to item 20 for release 8.36. New programs are recommended to use the
new library. Programs that use the original (PCRE1) API will need changing
before linking with the new library.

Generic instructions for the PCRE2 C libraries
Stack size in Windows environments

Building PCRE2 on Windows with CMake

Building PCRE2 under VMS
GENERAL
The source of the PCRE2 libraries consists entirely of code written in Standard
C, and so should compile successfully on any system that has a Standard C
compiler and library.
The PCRE2 distribution includes a "configure" file for use by the
configure/make (autotools) build system, as found in many Unix-like
environments. The README file contains information about the options for
"configure".
There is also support for CMake, which some users prefer, especially in Windows
environments, though it can also be run in Unix-like environments. See the
section entitled "Building PCRE2 on Windows with CMake" below.
Versions of src/config.h and src/pcre2.h are distributed in the PCRE2 tarballs
under the names src/config.h.generic and src/pcre2.h.generic. These are
provided for those who build PCRE2 without using "configure" or CMake. If you
use "configure" or CMake, the .generic versions are not used.
GENERIC INSTRUCTIONS FOR THE PCRE2 C LIBRARIES
There are three possible PCRE2 libraries, each handling data with a specific
code unit width: 8, 16, or 32 bits. You can build any combination of them. The
following are generic instructions for building a PCRE2 C library "by hand". If
you are going to use CMake, this section does not apply to you; you can skip
ahead to the CMake section. Note that the settings concerned with 8-bit,
16-bit, and 32-bit code units relate to the type of data string that PCRE2
processes. They are NOT referring to the underlying operating system bit width.
You do not have to do anything special to compile in a 64-bit environment, for
example.
(1) Copy or rename the file src/config.h.generic as src/config.h, and edit the
macro settings that it contains to whatever is appropriate for your
environment. In particular, you can alter the definition of the NEWLINE
macro to specify what character(s) you want to be interpreted as line
terminators by default. You need to #define at least one of
SUPPORT_PCRE2_8, SUPPORT_PCRE2_16, or SUPPORT_PCRE2_32, depending on which
libraries you are going to build. You must set all that apply.
When you subsequently compile any of the PCRE2 modules, you must specify
-DHAVE_CONFIG_H to your compiler so that src/config.h is included in the
sources.
An alternative approach is not to edit src/config.h, but to use -D on the
compiler command line to make any changes that you need to the
configuration options. In this case -DHAVE_CONFIG_H must not be set.
NOTE: There have been occasions when the way in which certain parameters
in src/config.h are used has changed between releases. (In the
configure/make world, this is handled automatically.) When upgrading to a
new release, you are strongly advised to review src/config.h.generic
before re-using what you had previously.
Note also that the src/config.h.generic file is created from a config.h
that was generated by Autotools, which automatically includes settings of
a number of macros that are not actually used by PCRE2 (for example,
HAVE_DLFCN_H).
(2) Copy or rename the file src/pcre2.h.generic as src/pcre2.h.
(3) EITHER:
Copy or rename file src/pcre2_chartables.c.dist as
src/pcre2_chartables.c.
OR:
Compile src/pcre2_dftables.c as a stand-alone program (using
-DHAVE_CONFIG_H if you have set up src/config.h), and then run it with
the single argument "src/pcre2_chartables.c". This generates a set of
standard character tables and writes them to that file. The tables are
generated using the default C locale for your system. If you want to use
a locale that is specified by LC_xxx environment variables, add the -L
option to the pcre2_dftables command. You must use this method if you
are building on a system that uses EBCDIC code.
The tables in src/pcre2_chartables.c are defaults. The caller of PCRE2 can
specify alternative tables at run time.
(4) For a library that supports 8-bit code units in the character strings that
it processes, compile the following source files from the src directory,
setting -DPCRE2_CODE_UNIT_WIDTH=8 as a compiler option. Also set
-DHAVE_CONFIG_H if you have set up src/config.h with your configuration,
or else use other -D settings to change the configuration as required.
pcre2_auto_possess.c
pcre2_chkdint.c
pcre2_chartables.c
pcre2_compile.c
pcre2_compile_class.c
pcre2_config.c
pcre2_context.c
pcre2_convert.c
pcre2_dfa_match.c
pcre2_error.c
pcre2_extuni.c
pcre2_find_bracket.c
pcre2_jit_compile.c
pcre2_maketables.c
pcre2_match.c
pcre2_match_data.c
pcre2_newline.c
pcre2_ord2utf.c
pcre2_pattern_info.c
pcre2_script_run.c
pcre2_serialize.c
pcre2_string_utils.c
pcre2_study.c
pcre2_substitute.c
pcre2_substring.c
pcre2_tables.c
pcre2_ucd.c
pcre2_valid_utf.c
pcre2_xclass.c
Make sure that you include -I. in the compiler command (or equivalent for
an unusual compiler) so that all included PCRE2 header files are first
sought in the src directory under the current directory. Otherwise you run
the risk of picking up a previously-installed file from somewhere else.
Note that you must compile pcre2_jit_compile.c, even if you have not
defined SUPPORT_JIT in src/config.h, because when JIT support is not
configured, dummy functions are compiled. When JIT support IS configured,
pcre2_jit_compile.c #includes other files from the sljit dependency,
all of whose names begin with "sljit". It also #includes
src/pcre2_jit_match.c and src/pcre2_jit_misc.c, so you should not compile
those yourself.
Note also that the pcre2_fuzzsupport.c file contains special code that is
useful to those who want to run fuzzing tests on the PCRE2 library. Unless
you are doing that, you can ignore it.
(5) Now link all the compiled code into an object library in whichever form
your system keeps such libraries. This is the PCRE2 C 8-bit library,
typically called something like libpcre2-8. If your system has static and
shared libraries, you may have to do this once for each type.
(6) If you want to build a library that supports 16-bit or 32-bit code units,
set 16 or 32 as the value of -DPCRE2_CODE_UNIT_WIDTH when obeying step 4
above. If you want to build more than one PCRE2 library, repeat steps 4
and 5 as necessary.
(7) If you want to build the POSIX wrapper functions (which apply only to the
8-bit library), ensure that you have the src/pcre2posix.h file and then
compile src/pcre2posix.c. Link the result (on its own) as the pcre2posix
library. If targeting a DLL in Windows, make sure to include
-DPCRE2POSIX_SHARED with your compiler flags.
(8) The pcre2test program can be linked with any combination of the 8-bit,
16-bit and 32-bit libraries (depending on what you specfied in
src/config.h) . Compile src/pcre2test.c; don't forget -DHAVE_CONFIG_H if
necessary, but do NOT define PCRE2_CODE_UNIT_WIDTH. Then link with the
appropriate library/ies. If you compiled an 8-bit library, pcre2test also
needs the pcre2posix wrapper library.
(9) Run pcre2test on the testinput files in the testdata directory, and check
that the output matches the corresponding testoutput files. There are
comments about what each test does in the section entitled "Testing PCRE2"
in the README file. If you compiled more than one of the 8-bit, 16-bit and
32-bit libraries, you need to run pcre2test with the -16 option to do
16-bit tests and with the -32 option to do 32-bit tests.
Some tests are relevant only when certain build-time options are selected.
For example, test 4 is for Unicode support, and will not run if you have
built PCRE2 without it. See the comments at the start of each testinput
file. If you have a suitable Unix-like shell, the RunTest script will run
the appropriate tests for you. The command "RunTest list" will output a
list of all the tests.
Note that the supplied files are in Unix format, with just LF characters
as line terminators. You may need to edit them to change this if your
system uses a different convention.
(10) If you have built PCRE2 with SUPPORT_JIT, the JIT features can be tested
by running pcre2test with the -jit option. This is done automatically by
the RunTest script. You might also like to build and run the freestanding
JIT test program, src/pcre2_jit_test.c.
(11) The pcre2test program tests the POSIX wrapper library, but there is also a
freestanding test program in src/pcre2posix_test.c. It must be linked with
both the pcre2posix library and the 8-bit PCRE2 library.
(12) If you want to use the pcre2grep command, compile and link
src/pcre2grep.c; it uses only the 8-bit PCRE2 library (it does not need
the pcre2posix library). If you have built the PCRE2 library with JIT
support by defining SUPPORT_JIT in src/config.h, you can also define
SUPPORT_PCRE2GREP_JIT, which causes pcre2grep to make use of JIT (unless
it is run with --no-jit). If you define SUPPORT_PCRE2GREP_JIT without
defining SUPPORT_JIT, pcre2grep does not try to make use of JIT.
STACK SIZE IN WINDOWS ENVIRONMENTS
Prior to release 10.30 the default system stack size of 1MiB in some Windows
environments caused issues with some tests. This should no longer be the case
for 10.30 and later releases.
LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
If you want to statically link a program against a PCRE2 library in the form of
a non-dll .a file, you must define PCRE2_STATIC before including src/pcre2.h.
CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
It is possible to compile programs to use different calling conventions using
MSVC. Search the web for "calling conventions" for more information. To make it
easier to change the calling convention for the exported functions in a
PCRE2 library, the macro PCRE2_CALL_CONVENTION is present in all the external
definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
not set, it defaults to empty; the default calling convention is then used
(which is what is wanted most of the time).
COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE2 ON WINDOWS WITH CMAKE")
There are two ways of building PCRE2 using the "configure, make, make install"
paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
the same thing; they are completely different from each other. There is also
support for building using CMake, which some users find a more straightforward
way of building PCRE2 under Windows.
The MinGW home page (http://www.mingw.org/) says this:
MinGW: A collection of freely available and freely distributable Windows
specific header files and import libraries combined with GNU toolsets that
allow one to produce native Windows programs that do not rely on any
3rd-party C runtime DLLs.
The Cygwin home page (http://www.cygwin.com/) says this:
Cygwin is a Linux-like environment for Windows. It consists of two parts:
. A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
substantial Linux API functionality
. A collection of tools which provide Linux look and feel.
On both MinGW and Cygwin, PCRE2 should build correctly using:
./configure && make && make install
This should create two libraries called libpcre2-8 and libpcre2-posix. These
are independent libraries: when you link with libpcre2-posix you must also link
with libpcre2-8, which contains the basic functions.
Using Cygwin's compiler generates libraries and executables that depend on
cygwin1.dll. If a library that is generated this way is distributed,
cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
licence, this forces not only PCRE2 to be under the GPL, but also the entire
application. A distributor who wants to keep their own code proprietary must
purchase an appropriate Cygwin licence.
MinGW has no such restrictions. The MinGW compiler generates a library or
executable that can run standalone on Windows without any third party dll or
licensing issues.
But there is more complication:
If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
gcc and MinGW's gcc). So, a user can:
. Build native binaries by using MinGW or by getting Cygwin and using
-mno-cygwin.
. Build binaries that depend on cygwin1.dll by using Cygwin with the normal
compiler flags.
The test files that are supplied with PCRE2 are in UNIX format, with LF
characters as line terminators. Unless your PCRE2 library uses a default
newline option that includes LF as a valid newline, it may be necessary to
change the line terminators in the test files to get some of the tests to work.
BUILDING PCRE2 ON WINDOWS WITH CMAKE
CMake is an alternative configuration facility that can be used instead of
"configure". CMake creates project files (make files, solution files, etc.)
tailored to numerous development environments, including Visual Studio,
Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no
spaces in the names for your CMake installation and your PCRE2 source and build
directories.
If you are using CMake and encounter errors, deleting the CMake cache and
restarting from a fresh build may fix the error. In the CMake GUI, the cache can
be deleted by selecting "File > Delete Cache"; or the folder "CMakeCache" can
be deleted.
1. Install the latest CMake version available from http://www.cmake.org/, and
ensure that cmake\bin is on your path.
2. Unzip (retaining folder structure) the PCRE2 source tree into a source
directory such as C:\pcre2. You should ensure your local date and time
is not earlier than the file dates in your source dir if the release is
very new.
3. Create a new, empty build directory, preferably a subdirectory of the
source dir. For example, C:\pcre2\pcre2-xx\build.
4. Run CMake.
- Using the CLI, simply run `cmake ..` inside the `build/` directory. You can
use the `ccmake` ncurses GUI to select and configure PCRE2 features.
- Using the CMake GUI:
a) Run cmake-gui from the Shell environment of your build tool, for
example, Msys for Msys/MinGW or Visual Studio Command Prompt for
VC/VC++.
b) Enter C:\pcre2\pcre2-xx and C:\pcre2\pcre2-xx\build for the source and
build directories, respectively.
c) Press the "Configure" button.
d) Select the particular IDE / build tool that you are using (Visual
Studio, MSYS makefiles, MinGW makefiles, etc.)
e) The GUI will then list several configuration options. This is where
you can disable Unicode support or select other PCRE2 optional features.
f) Press "Configure" again. The adjacent "Generate" button should now be
active.
g) Press "Generate".
5. The build directory should now contain a usable build system, be it a
solution file for Visual Studio, makefiles for MinGW, etc. Exit from
cmake-gui and use the generated build system with your compiler or IDE.
E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE2
solution, select the desired configuration (Debug, or Release, etc.) and
build the ALL_BUILD project.
Regardless of build system used, `cmake --build .` will build it.
6. If during configuration with cmake-gui you've elected to build the test
programs, you can execute them by building the test project. E.g., for
MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The
most recent build configuration is targeted by the tests. A summary of
test results is presented. Complete test output is subsequently
available for review in Testing\Temporary under your build dir.
Regardless of build system used, `ctest` will run the tests.
BUILDING PCRE2 ON WINDOWS WITH VISUAL STUDIO
The code currently cannot be compiled without an inttypes.h header, which is
available only with Visual Studio 2013 or newer. However, this portable and
permissively-licensed implementation of the stdint.h header could be used as an
alternative:
http://www.azillionmonkeys.com/qed/pstdint.h
Just rename it and drop it into the top level of the build tree.
TESTING WITH RUNTEST.BAT
If configured with CMake, building the test project ("make test" or building
ALL_TESTS in Visual Studio) creates (and runs) pcre2_test.bat (and depending
on your configuration options, possibly other test programs) in the build
directory. The pcre2_test.bat script runs RunTest.bat with correct source and
exe paths.
For manual testing with RunTest.bat, provided the build dir is a subdirectory
of the source directory: Open command shell window. Chdir to the location
of your pcre2test.exe and pcre2grep.exe programs. Call RunTest.bat with
"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate.
To run only a particular test with RunTest.Bat provide a test number argument.
Otherwise:
1. Copy RunTest.bat into the directory where pcre2test.exe and pcre2grep.exe
have been created.
2. Edit RunTest.bat to identify the full or relative location of
the pcre2 source (wherein which the testdata folder resides), e.g.:
set srcdir=C:\pcre2\pcre2-10.00
3. In a Windows command environment, chdir to the location of your bat and
exe programs.
4. Run RunTest.bat. Test outputs will automatically be compared to expected
results, and discrepancies will be identified in the console output.
To independently test the just-in-time compiler, run pcre2_jit_test.exe.
BUILDING PCRE2 ON NATIVE Z/OS AND Z/VM
z/OS and z/VM are operating systems for mainframe computers, produced by IBM.
The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and
applications can be supported through UNIX System Services, and in such an
environment it should be possible to build PCRE2 in the same way as in other
systems, with the EBCDIC related configuration settings, but it is not known if
anybody has tried this.
In native z/OS (without UNIX System Services) and in z/VM, special ports are
required. For details, please see file 939 on this web site:
http://www.cbttape.org
Everything in that location, source and executable, is in EBCDIC and native
z/OS file formats. The port provides an API for LE languages such as COBOL and
for the z/OS and z/VM versions of the Rexx languages.
BUILDING PCRE2 UNDER VMS
Alexey Chuphin has contributed some auxiliary files for building PCRE2 under
OpenVMS. They are in the "vms" directory in the distribution tarball. Please
read the file called vms/openvms_readme.txt. The pcre2test and pcre2grep
programs contain some VMS-specific code.

README file for PCRE2 (Perl-compatible regular expression library)
------------------------------------------------------------------
PCRE2 is a re-working of the original PCRE1 library to provide an entirely new
API. Since its initial release in 2015, there has been further development of
the code and it now differs from PCRE1 in more than just the API. There are new
features, and the internals have been improved. The original PCRE1 library is
now obsolete and no longer maintained. The latest release of PCRE2 is available
in .tar.gz, tar.bz2, or .zip form from this GitHub repository:
https://github.com/PCRE2Project/pcre2/releases
There is a mailing list for discussion about the development of PCRE2 at
pcre2-dev@googlegroups.com. You can subscribe by sending an email to
pcre2-dev+subscribe@googlegroups.com.
You can access the archives and also subscribe or manage your subscription

The PCRE2 APIs
--------------
PCRE2 is written in C, and it has its own API. There are three sets of
functions, one for the 8-bit library, which processes strings of bytes, one for
the 16-bit library, which processes strings of 16-bit values, and one for the
32-bit library, which processes strings of 32-bit values. Unlike PCRE1, there
are no C++ wrappers.
The distribution does contain a set of C wrapper functions for the 8-bit
library that are based on the POSIX regular expression API (see the pcre2posix
man page). These are built into a library called libpcre2-posix. Note that this
just provides a POSIX calling interface to PCRE2; the regular expressions
themselves still follow Perl syntax and semantics. The POSIX API is restricted,
and does not give full access to all of PCRE2's facilities.
The header file for the POSIX-style functions is called pcre2posix.h. The
official POSIX name is regex.h, but I did not want to risk possible problems
with existing files of that name by distributing it that way. To use PCRE2 with
an existing program that uses the POSIX API, pcre2posix.h will have to be
renamed or pointed at by a link (or the program modified, of course). See the
pcre2posix documentation for more details.
Documentation for PCRE2
-----------------------
If you install PCRE2 in the normal way on a Unix-like system, you will end up
with a set of man pages whose names all start with "pcre2". The one that is
just called "pcre2" lists all the others. In addition to these man pages, the
PCRE2 documentation is supplied in two other forms:
1. There are files called doc/pcre2.txt, doc/pcre2grep.txt, and
doc/pcre2test.txt in the source distribution. The first of these is a
concatenation of the text forms of all the section 3 man pages except the
listing of pcre2demo.c and those that summarize individual functions. The
other two are the text forms of the section 1 man pages for the pcre2grep
and pcre2test commands. These text forms are provided for ease of scanning
with text editors or similar tools. They are installed in
<prefix>/share/doc/pcre2, where <prefix> is the installation prefix
(defaulting to /usr/local).
2. A set of files containing all the documentation in HTML form, hyperlinked
in various ways, and rooted in a file called index.html, is distributed in
doc/html and installed in <prefix>/share/doc/pcre2/html.
Building PCRE2 on non-Unix-like systems
---------------------------------------
For a non-Unix-like system, please read the file NON-AUTOTOOLS-BUILD, though if
your system supports the use of "configure" and "make" you may be able to build
PCRE2 using autotools in the same way as for many Unix-like systems.
PCRE2 can also be configured using CMake, which can be run in various ways
(command line, GUI, etc). This creates Makefiles, solution files, etc. The file
NON-AUTOTOOLS-BUILD has information about CMake.
PCRE2 has been compiled on many different operating systems. It should be
straightforward to build PCRE2 on any system that has a Standard C compiler and
library, because it uses only Standard C functions.
Building PCRE2 without using autotools
--------------------------------------
The use of autotools (in particular, libtool) is problematic in some
environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD
file for ways of building PCRE2 without using autotools.
Building PCRE2 using autotools
------------------------------
The following instructions assume the use of the widely used "configure; make;
make install" (autotools) process.
If you have downloaded and unpacked a PCRE2 release tarball, run the
"configure" command from the PCRE2 directory, with your current directory set
to the directory where you want the files to be created. This command is a
standard GNU "autoconf" configuration script, for which generic instructions
are supplied in the file INSTALL.
The files in the GitHub repository do not contain "configure". If you have
downloaded the PCRE2 source files from GitHub, before you can run "configure"
you must run the shell script called autogen.sh. This runs a number of
autotools to create a "configure" script (you must of course have the autotools
commands installed in order to do this).
Most commonly, people build PCRE2 within its own distribution directory, and in
this case, on many systems, just running "./configure" is sufficient. However,
the usual methods of changing standard defaults are available. For example:
CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
This command specifies that the C compiler should be run with the flags '-O2
-Wall' instead of the default, and that "make install" should install PCRE2
under /opt/local instead of the default /usr/local.
If you want to build in a different directory, just run "configure" with that
directory as current. For example, suppose you have unpacked the PCRE2 source
into /source/pcre2/pcre2-xxx, but you want to build it in
/build/pcre2/pcre2-xxx:
cd /build/pcre2/pcre2-xxx
/source/pcre2/pcre2-xxx/configure
PCRE2 is written in C and is normally compiled as a C library. However, it is
possible to build it as a C++ library, though the provided building apparatus
does not have any features to support this.
There are some optional features that can be included or omitted from the PCRE2
library. They are also documented in the pcre2build man page.
. By default, both shared and static libraries are built. You can change this
by adding one of these options to the "configure" command:
--disable-shared
--disable-static
Setting --disable-shared ensures that PCRE2 libraries are built as static
libraries. The binaries that are then created as part of the build process
(for example, pcre2test and pcre2grep) are linked statically with one or more
PCRE2 libraries, but may also be dynamically linked with other libraries such
as libc. If you want these binaries to be fully statically linked, you can
set LDFLAGS like this:
LDFLAGS=--static ./configure --disable-shared
Note the two hyphens in --static. Of course, this works only if static
versions of all the relevant libraries are available for linking. See also
"Shared libraries" below.
. By default, only the 8-bit library is built. If you add --enable-pcre2-16 to
the "configure" command, the 16-bit library is also built. If you add
--enable-pcre2-32 to the "configure" command, the 32-bit library is also
built. If you want only the 16-bit or 32-bit library, use --disable-pcre2-8
to disable building the 8-bit library.
. If you want to include support for just-in-time (JIT) compiling, which can
give large performance improvements on certain platforms, add --enable-jit to
the "configure" command. This support is available only for certain hardware
architectures. If you try to enable it on an unsupported architecture, there
will be a compile time error. If in doubt, use --enable-jit=auto, which
enables JIT only if the current hardware is supported.
. If you are enabling JIT under SELinux environment you may also want to add
--enable-jit-sealloc, which enables the use of an executable memory allocator
that is compatible with SELinux. Warning: this allocator is experimental!
It does not support fork() operation and may crash when no disk space is
available. This option has no effect if JIT is disabled.
. If you do not want to make use of the default support for UTF-8 Unicode
character strings in the 8-bit library, UTF-16 Unicode character strings in
the 16-bit library, or UTF-32 Unicode character strings in the 32-bit
library, you can add --disable-unicode to the "configure" command. This
reduces the size of the libraries. It is not possible to configure one
library with Unicode support, and another without, in the same configuration.
It is also not possible to use --enable-ebcdic (see below) with Unicode
support, so if this option is set, you must also use --disable-unicode.
When Unicode support is available, the use of a UTF encoding still has to be
enabled by setting the PCRE2_UTF option at run time or starting a pattern
with (*UTF). When PCRE2 is compiled with Unicode support, its input can only
either be ASCII or UTF-8/16/32, even when running on EBCDIC platforms.
As well as supporting UTF strings, Unicode support includes support for the
\P, \p, and \X sequences that recognize Unicode character properties.
However, only a subset of Unicode properties are supported; see the
pcre2pattern man page for details. Escape sequences such as \d and \w in
patterns do not by default make use of Unicode properties, but can be made to
do so by setting the PCRE2_UCP option or starting a pattern with (*UCP).
. You can build PCRE2 to recognize either CR or LF or the sequence CRLF, or any
of the preceding, or any of the Unicode newline sequences, or the NUL (zero)
character as indicating the end of a line. Whatever you specify at build time
is the default; the caller of PCRE2 can change the selection at run time. The
default newline indicator is a single LF character (the Unix standard). You
can specify the default newline indicator by adding --enable-newline-is-cr,
--enable-newline-is-lf, --enable-newline-is-crlf,
--enable-newline-is-anycrlf, --enable-newline-is-any, or
--enable-newline-is-nul to the "configure" command, respectively.
. By default, the sequence \R in a pattern matches any Unicode line ending
sequence. This is independent of the option specifying what PCRE2 considers
to be the end of a line (see above). However, the caller of PCRE2 can
restrict \R to match only CR, LF, or CRLF. You can make this the default by
adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").
. In a pattern, the escape sequence \C matches a single code unit, even in a
UTF mode. This can be dangerous because it breaks up multi-code-unit
characters. You can build PCRE2 with the use of \C permanently locked out by
adding --enable-never-backslash-C (note the upper case C) to the "configure"
command. When \C is allowed by the library, individual applications can lock
it out by calling pcre2_compile() with the PCRE2_NEVER_BACKSLASH_C option.
. PCRE2 has a counter that limits the depth of nesting of parentheses in a
pattern. This limits the amount of system stack that a pattern uses when it
is compiled. The default is 250, but you can change it by setting, for
example,
--with-parens-nest-limit=500
. PCRE2 has a counter that can be set to limit the amount of computing resource
it uses when matching a pattern. If the limit is exceeded during a match, the
match fails. The default is ten million. You can change the default by
setting, for example,
--with-match-limit=500000
on the "configure" command. This is just the default; individual calls to
pcre2_match() or pcre2_dfa_match() can supply their own value. There is more
discussion in the pcre2api man page (search for pcre2_set_match_limit).
. There is a separate counter that limits the depth of nested backtracking
(pcre2_match()) or nested function calls (pcre2_dfa_match()) during a
matching process, which indirectly limits the amount of heap memory that is
used, and in the case of pcre2_dfa_match() the amount of stack as well. This
counter also has a default of ten million, which is essentially "unlimited".
You can change the default by setting, for example,
--with-match-limit-depth=5000
There is more discussion in the pcre2api man page (search for
pcre2_set_depth_limit).
. You can also set an explicit limit on the amount of heap memory used by
the pcre2_match() and pcre2_dfa_match() interpreters:
--with-heap-limit=500
The units are kibibytes (units of 1024 bytes). This limit does not apply when
the JIT optimization (which has its own memory control features) is used.
There is more discussion on the pcre2api man page (search for
pcre2_set_heap_limit).
. In the 8-bit library, the default maximum compiled pattern size is around
64 kibibytes. You can increase this by adding --with-link-size=3 to the
"configure" command. PCRE2 then uses three bytes instead of two for offsets
to different parts of the compiled pattern. In the 16-bit library,
--with-link-size=3 is the same as --with-link-size=4, which (in both
libraries) uses four-byte offsets. Increasing the internal link size reduces
performance in the 8-bit and 16-bit libraries. In the 32-bit library, the
link size setting is ignored, as 4-byte offsets are always used.
. Lookbehind assertions in which one or more branches can match a variable
number of characters are supported only if there is a maximum matching length
for each top-level branch. There is a limit to this maximum that defaults to
255 characters. You can alter this default by a setting such as
--with-max-varlookbehind=100
The limit can be changed at runtime by calling pcre2_set_max_varlookbehind().
Lookbehind assertions in which every branch matches a fixed number of
characters (not necessarily all the same) are not constrained by this limit.
. For speed, PCRE2 uses four tables for manipulating and identifying characters
whose code point values are less than 256. By default, it uses a set of
tables for ASCII encoding that is part of the distribution. If you specify
--enable-rebuild-chartables
a program called pcre2_dftables is compiled and run in the default C locale
when you obey "make". It builds a source file called pcre2_chartables.c. If
you do not specify this option, pcre2_chartables.c is created as a copy of
pcre2_chartables.c.dist. See "Character tables" below for further
information.
. It is possible to compile PCRE2 for use on systems that use EBCDIC as their
character code (as opposed to ASCII/Unicode) by specifying
--enable-ebcdic --disable-unicode
This automatically implies --enable-rebuild-chartables (see above). However,
when PCRE2 is built this way, it always operates in EBCDIC. It cannot support
both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25,
which specifies that the code value for the EBCDIC NL character is 0x25
instead of the default 0x15.
. If you specify --enable-debug, additional debugging code is included in the
build. This option is intended for use by the PCRE2 maintainers.
. In environments where valgrind is installed, if you specify
--enable-valgrind
PCRE2 will use valgrind annotations to mark certain memory regions as
unaddressable. This allows it to detect invalid memory accesses, and is
mostly useful for debugging PCRE2 itself.
. In environments where the gcc compiler is used and lcov is installed, if you
specify
--enable-coverage
the build process implements a code coverage report for the test suite. The
report is generated by running "make coverage". If ccache is installed on
your system, it must be disabled when building PCRE2 for coverage reporting.
You can do this by setting the environment variable CCACHE_DISABLE=1 before
running "make" to build PCRE2. There is more information about coverage
reporting in the "pcre2build" documentation.
. When JIT support is enabled, pcre2grep automatically makes use of it, unless
you add --disable-pcre2grep-jit to the "configure" command.
. There is support for calling external programs during matching in the
pcre2grep command, using PCRE2's callout facility with string arguments. This
support can be disabled by adding --disable-pcre2grep-callout to the
"configure" command. There are two kinds of callout: one that generates
output from inbuilt code, and another that calls an external program. The
latter has special support for Windows and VMS; otherwise it assumes the
existence of the fork() function. This facility can be disabled by adding
--disable-pcre2grep-callout-fork to the "configure" command.
. The pcre2grep program currently supports only 8-bit data files, and so
requires the 8-bit PCRE2 library. It is possible to compile pcre2grep to use
libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by
specifying one or both of
--enable-pcre2grep-libz
--enable-pcre2grep-libbz2
Of course, the relevant libraries must be installed on your system.
. The default starting size (in bytes) of the internal buffer used by pcre2grep
can be set by, for example:
--with-pcre2grep-bufsize=51200
The value must be a plain integer. The default is 20480. The amount of memory
used by pcre2grep is actually three times this number, to allow for "before"
and "after" lines. If very long lines are encountered, the buffer is
automatically enlarged, up to a fixed maximum size.
. The default maximum size of pcre2grep's internal buffer can be set by, for
example:
--with-pcre2grep-max-bufsize=2097152
The default is either 1048576 or the value of --with-pcre2grep-bufsize,
whichever is the larger.
. It is possible to compile pcre2test so that it links with the libreadline
or libedit libraries, by specifying, respectively,
--enable-pcre2test-libreadline or --enable-pcre2test-libedit
If this is done, when pcre2test's input is from a terminal, it reads it using
the readline() function. This provides line-editing and history facilities.
Note that libreadline is GPL-licensed, so if you distribute a binary of
pcre2test linked in this way, there may be licensing issues. These can be
avoided by linking with libedit (which has a BSD licence) instead.
Enabling libreadline causes the -lreadline option to be added to the
pcre2test build. In many operating environments with a system-installed
readline library this is sufficient. However, in some environments (e.g. if
an unmodified distribution version of readline is in use), it may be
necessary to specify something like LIBS="-lncurses" as well. This is
because, to quote the readline INSTALL, "Readline uses the termcap functions,
but does not link with the termcap or curses library itself, allowing
applications which link with readline the option to choose an appropriate
library." If you get error messages about missing functions tgetstr, tgetent,
tputs, tgetflag, or tgoto, this is the problem, and linking with the ncurses
library should fix it.
. The C99 standard defines formatting modifiers z and t for size_t and
ptrdiff_t values, respectively. By default, PCRE2 uses these modifiers in
environments other than Microsoft Visual Studio versions earlier than 2013
when __STDC_VERSION__ is defined and has a value greater than or equal to
199901L (indicating C99). However, there is at least one environment that
claims to be C99 but does not support these modifiers. If
--disable-percent-zt is specified, no use is made of the z or t modifiers.
Instead of %td or %zu, %lu is used, with a cast for size_t values.
. There is a special option called --enable-fuzz-support for use by people who
want to run fuzzing tests on PCRE2. If set, it causes an extra library
called libpcre2-fuzzsupport.a to be built, but not installed. This contains
a single function called LLVMFuzzerTestOneInput() whose arguments are a
pointer to a string and the length of the string. When called, this function
tries to compile the string as a pattern, and if that succeeds, to match
it. This is done both with no options and with some random options bits that
are generated from the string. Setting --enable-fuzz-support also causes an
executable called pcre2fuzzcheck-{8,16,32} to be created. This is normally
run under valgrind or used when PCRE2 is compiled with address sanitizing
enabled. It calls the fuzzing function and outputs information about what it
is doing. The input strings are specified by arguments: if an argument
starts with "=" the rest of it is a literal input string. Otherwise, it is
assumed to be a file name, and the contents of the file are the test string.
. Releases before 10.30 could be compiled with --disable-stack-for-recursion,
which caused pcre2_match() to use individual blocks on the heap for
backtracking instead of recursive function calls (which use the stack). This
is now obsolete because pcre2_match() was refactored always to use the heap
(in a much more efficient way than before). This option is retained for
backwards compatibility, but has no effect other than to output a warning.
The "configure" script builds the following files for the basic C library:
. Makefile the makefile that builds the library
. src/config.h build-time configuration options for the library
. src/pcre2.h the public PCRE2 header file
. pcre2-config script that shows the building settings such as CFLAGS
that were set for "configure"
. libpcre2-8.pc )
. libpcre2-16.pc ) data for the pkg-config command
. libpcre2-32.pc )
. libpcre2-posix.pc )
. libtool script that builds shared and/or static libraries
Versions of config.h and pcre2.h are distributed in the src directory of PCRE2
tarballs under the names config.h.generic and pcre2.h.generic. These are
provided for those who have to build PCRE2 without using "configure" or CMake.
If you use "configure" or CMake, the .generic versions are not used.
The "configure" script also creates config.status, which is an executable
script that can be run to recreate the configuration, and config.log, which
contains compiler output from tests that "configure" runs.
Once "configure" has run, you can run "make". This builds whichever of the
libraries libpcre2-8, libpcre2-16 and libpcre2-32 are configured, and a test
program called pcre2test. If you enabled JIT support with --enable-jit, another
test program called pcre2_jit_test is built as well. If the 8-bit library is
built, libpcre2-posix, pcre2posix_test, and the pcre2grep command are also
built. Running "make" with the -j option may speed up compilation on
multiprocessor systems.
The command "make check" runs all the appropriate tests. Details of the PCRE2
tests are given below in a separate section of this document. The -j option of
"make" can also be used when running the tests.
You can use "make install" to install PCRE2 into live directories on your
system. The following are installed (file names are all relative to the
<prefix> that is set when "configure" is run):
Commands (bin):
pcre2test
pcre2grep (if 8-bit support is enabled)
pcre2-config
Libraries (lib):
libpcre2-8 (if 8-bit support is enabled)
libpcre2-16 (if 16-bit support is enabled)
libpcre2-32 (if 32-bit support is enabled)

If you want to remove PCRE2 from your system, you can run "make uninstall".
This removes all the files that "make install" installed. However, it does not
remove any directories, because these are often shared with other programs.
Retrieving configuration information
------------------------------------
Running "make install" installs the command pcre2-config, which can be used to
recall information about the PCRE2 configuration and installation. For example:
pcre2-config --version
prints the version number, and
pcre2-config --libs8
outputs information about where the 8-bit library is installed. This command
can be included in makefiles for programs that use PCRE2, saving the programmer
from having to remember too many details. Run pcre2-config with no arguments to
obtain a list of possible arguments.
The pkg-config command is another system for saving and retrieving information
about installed libraries. Instead of separate commands for each library, a
single command is used. For example:
pkg-config --libs libpcre2-16
The data is held in *.pc files that are installed in a directory called
<prefix>/lib/pkgconfig.
Shared libraries
----------------
The default distribution builds PCRE2 as shared libraries and static libraries,
as long as the operating system supports shared libraries. Shared library
support relies on the "libtool" script which is built as part of the
"configure" process.
The libtool script is used to compile and link both shared and static
libraries. They are placed in a subdirectory called .libs when they are newly
built. The programs pcre2test and pcre2grep are built to use these uninstalled
libraries (by means of wrapper scripts in the case of shared libraries). When
you use "make install" to install shared libraries, pcre2grep and pcre2test are
automatically re-built to use the newly installed shared libraries before being
installed themselves. However, the versions left in the build directory still
use the uninstalled libraries.
To build PCRE2 using static libraries only you must use --disable-shared when
configuring it. For example:
./configure --prefix=/usr/gnu --disable-shared
Then run "make" in the usual way. Similarly, you can use --disable-static to
build only shared libraries. Note, however, that when you build only static
libraries, binary programs such as pcre2test and pcre2grep may still be
dynamically linked with other libraries (for example, libc) unless you set
LDFLAGS to --static when running "configure".
Cross-compiling using autotools
-------------------------------
You can specify CC and CFLAGS in the normal way to the "configure" command, in
order to cross-compile PCRE2 for some other host. However, you should NOT
specify --enable-rebuild-chartables, because if you do, the pcre2_dftables.c
source file is compiled and run on the local host, in order to generate the
inbuilt character tables (the pcre2_chartables.c file). This will probably not
work, because pcre2_dftables.c needs to be compiled with the local compiler,
not the cross compiler.
When --enable-rebuild-chartables is not specified, pcre2_chartables.c is
created by making a copy of pcre2_chartables.c.dist, which is a default set of
tables that assumes ASCII code. Cross-compiling with the default tables should
not be a problem.
If you need to modify the character tables when cross-compiling, you should
move pcre2_chartables.c.dist out of the way, then compile pcre2_dftables.c by
hand and run it on the local host to make a new version of
pcre2_chartables.c.dist. See the pcre2build section "Creating character tables
at build time" for more details.
Making new tarballs
-------------------
The command "make dist" creates three PCRE2 tarballs, in tar.gz, tar.bz2, and
zip formats. The command "make distcheck" does the same, but then does a trial
build of the new distribution to ensure that it works.
If you have modified any of the man page sources in the doc directory, you
should first run the maint/PrepareRelease script before making a distribution.
This script creates the .txt and HTML forms of the documentation from the man
pages.
Testing PCRE2
-------------
To test the basic PCRE2 library on a Unix-like system, run the RunTest script.
There is another script called RunGrepTest that tests the pcre2grep command.
When the 8-bit library is built, a test program for the POSIX wrapper, called
pcre2posix_test, is compiled, and when JIT support is enabled, a test program
called pcre2_jit_test is built. The scripts and the program tests are all run
when you obey "make check". For other environments, see the instructions in
NON-AUTOTOOLS-BUILD.
The RunTest script runs the pcre2test test program (which is documented in its
own man page) on each of the relevant testinput files in the testdata
directory, and compares the output with the contents of the corresponding
testoutput files. RunTest uses a file called testtry to hold the main output
from pcre2test. Other files whose names begin with "test" are used as working
files in some tests.
Some tests are relevant only when certain build-time options were selected. For
example, the tests for UTF-8/16/32 features are run only when Unicode support
is available. RunTest outputs a comment when it skips a test.
Many (but not all) of the tests that are not skipped are run twice if JIT
support is available. On the second run, JIT compilation is forced. This
testing can be suppressed by putting "-nojit" on the RunTest command line.
The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit
libraries that are enabled. If you want to run just one set of tests, call
RunTest with either the -8, -16 or -32 option.
If valgrind is installed, you can run the tests under it by putting "-valgrind"
on the RunTest command line. To run pcre2test on just one or more specific test
files, give their numbers as arguments to RunTest, for example:
RunTest 2 7 11
You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the
end), or a number preceded by ~ to exclude a test. For example:
Runtest 3-15 ~10
This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests
except test 13. Whatever order the arguments are in, the tests are always run
in numerical order.
You can also call RunTest with the single argument "list" to cause it to output
a list of tests.
The test sequence starts with "test 0", which is a special test that has no
input file, and whose output is not checked. This is because it will be
different on different hardware and with different configurations. The test
exists in order to exercise some of pcre2test's code that would not otherwise
be run.
Tests 1 and 2 can always be run, as they expect only plain text strings (not
UTF) and make no use of Unicode properties. The first test file can be fed
directly into the perltest.sh script to check that Perl gives the same results.
The only difference you should see is in the first few lines, where the Perl
version is given instead of the PCRE2 version. The second set of tests check
auxiliary functions, error detection, and run-time flags that are specific to
PCRE2. It also uses the debugging flags to check some of the internals of
pcre2_compile().
If you build PCRE2 with a locale setting that is not the standard C locale, the
character tables may be different (see next paragraph). In some cases, this may
cause failures in the second set of tests. For example, in a locale where the
isprint() function yields TRUE for characters in the range 128-255, the use of
[:isascii:] inside a character class defines a different set of characters, and
this shows up in this test as a difference in the compiled code, which is being
listed for checking. For example, where the comparison test output contains
[\x00-\x7f] the test might contain [\x00-\xff], and similarly in some other
cases. This is not a bug in PCRE2.
Test 3 checks pcre2_maketables(), the facility for building a set of character
tables for a specific locale and using them instead of the default tables. The
script uses the "locale" command to check for the availability of the "fr_FR",
"french", or "fr" locale, and uses the first one that it finds. If the "locale"
command fails, or if its output doesn't include "fr_FR", "french", or "fr" in
the list of available locales, the third test cannot be run, and a comment is
output to say why. If running this test produces an error like this:
** Failed to set locale "fr_FR"
it means that the given locale is not available on your system, despite being
listed by "locale". This does not mean that PCRE2 is broken. There are three
alternative output files for the third test, because three different versions
of the French locale have been encountered. The test passes if its output
matches any one of them.
Tests 4 and 5 check UTF and Unicode property support, test 4 being compatible
with the perltest.sh script, and test 5 checking PCRE2-specific things.
Tests 6 and 7 check the pcre2_dfa_match() alternative matching function, in
non-UTF mode and UTF-mode with Unicode property support, respectively.
Test 8 checks some internal offsets and code size features, but it is run only
when Unicode support is enabled. The output is different in 8-bit, 16-bit, and
32-bit modes and for different link sizes, so there are different output files
for each mode and link size.
Tests 9 and 10 are run only in 8-bit mode, and tests 11 and 12 are run only in
16-bit and 32-bit modes. These are tests that generate different output in
8-bit mode. Each pair are for general cases and Unicode support, respectively.
Test 13 checks the handling of non-UTF characters greater than 255 by
pcre2_dfa_match() in 16-bit and 32-bit modes.
Test 14 contains some special UTF and UCP tests that give different output for
different code unit widths.
Test 15 contains a number of tests that must not be run with JIT. They check,
among other non-JIT things, the match-limiting features of the interpretive
matcher.
Test 16 is run only when JIT support is not available. It checks that an
attempt to use JIT has the expected behaviour.
Test 17 is run only when JIT support is available. It checks JIT complete and
partial modes, match-limiting under JIT, and other JIT-specific features.
Tests 18 and 19 are run only in 8-bit mode. They check the POSIX interface to
the 8-bit library, without and with Unicode support, respectively.
Test 20 checks the serialization functions by writing a set of compiled
patterns to a file, and then reloading and checking them.
Tests 21 and 22 test \C support when the use of \C is not locked out, without
and with UTF support, respectively. Test 23 tests \C when it is locked out.
Tests 24 and 25 test the experimental pattern conversion functions, without and
with UTF support, respectively.
Test 26 checks Unicode property support using tests that are generated
automatically from the Unicode data tables.
Character tables
----------------
For speed, PCRE2 uses four tables for manipulating and identifying characters
whose code point values are less than 256. By default, a set of tables that is
built into the library is used. The pcre2_maketables() function can be called
by an application to create a new set of tables in the current locale. This are
passed to PCRE2 by calling pcre2_set_character_tables() to put a pointer into a
compile context.
The source file called pcre2_chartables.c contains the default set of tables.
By default, this is created as a copy of pcre2_chartables.c.dist, which
contains tables for ASCII coding. However, if --enable-rebuild-chartables is
specified for ./configure, a new version of pcre2_chartables.c is built by the
program pcre2_dftables (compiled from pcre2_dftables.c), which uses the ANSI C
character handling functions such as isalnum(), isalpha(), isupper(),
islower(), etc. to build the table sources. This means that the default C
locale that is set for your system will control the contents of these default
tables. You can change the default tables by editing pcre2_chartables.c and
then re-building PCRE2. If you do this, you should take care to ensure that the
file does not get automatically re-generated. The best way to do this is to
move pcre2_chartables.c.dist out of the way and replace it with your customized
tables.
When the pcre2_dftables program is run as a result of specifying
--enable-rebuild-chartables, it uses the default C locale that is set on your
system. It does not pay attention to the LC_xxx environment variables. In other
words, it uses the system's default locale rather than whatever the compiling
user happens to have set. If you really do want to build a source set of
character tables in a locale that is specified by the LC_xxx variables, you can
run the pcre2_dftables program by hand with the -L option. For example:
./pcre2_dftables -L pcre2_chartables.c.special
The second argument names the file where the source code for the tables is
written. The first two 256-byte tables provide lower casing and case flipping
functions, respectively. The next table consists of a number of 32-byte bit
maps which identify certain character classes such as digits, "word"
characters, white space, etc. These are used when building 32-byte bit maps
that represent character classes for code points less than 256. The final
256-byte table has bits indicating various character types, as follows:
1 white space character
2 letter
4 lower case letter
8 decimal digit
16 alphanumeric or '_'
You can also specify -b (with or without -L) when running pcre2_dftables. This
causes the tables to be written in binary instead of as source code. A set of
binary tables can be loaded into memory by an application and passed to
pcre2_compile() in the same way as tables created dynamically by calling
pcre2_maketables(). The tables are just a string of bytes, independent of
hardware characteristics such as endianness. This means they can be bundled
with an application that runs in different environments, to ensure consistent
behaviour.

# PCRE2 - Perl-Compatible Regular Expressions
The PCRE2 library is a set of C functions that implement regular expression
pattern matching using the same syntax and semantics as Perl 5. PCRE2 has its
own native API, as well as a set of wrapper functions that correspond to the
POSIX regular expression API. The PCRE2 library is free, even for building
proprietary software. It comes in three forms, for processing 8-bit, 16-bit,
or 32-bit code units, in either literal or UTF encoding.
PCRE2 was first released in 2015 to replace the API in the original PCRE
library, which is now obsolete and no longer maintained. As well as a more
flexible API, the code of PCRE2 has been much improved since the fork.
## Download
As well as downloading from the
[GitHub site](https://github.com/PCRE2Project/pcre2), you can download PCRE2
or the older, unmaintained PCRE1 library from an
[*unofficial* mirror](https://sourceforge.net/projects/pcre/files/) at SourceForge.
You can check out the PCRE2 source code via Git or Subversion:
git clone https://github.com/PCRE2Project/pcre2.git
svn co https://github.com/PCRE2Project/pcre2.git
## Contributed Ports
If you just need the command-line PCRE2 tools on Windows, precompiled binary
versions are available at this
[Rexegg page](http://www.rexegg.com/pcregrep-pcretest.html).
A PCRE2 port for z/OS, a mainframe operating system which uses EBCDIC as its
default character encoding, can be found at
[http://www.cbttape.org](http://www.cbttape.org/) (File 939).
## Documentation
You can read the PCRE2 documentation
[here](https://PCRE2Project.github.io/pcre2/doc/html/index.html).
Comparisons to Perl's regular expression semantics can be found in the
community authored Wikipedia entry for PCRE.
There is a curated summary of changes for each PCRE release, copies of
documentation from older releases, and other useful information from the third
party authored
[RexEgg PCRE Documentation and Change Log page](http://www.rexegg.com/pcre-documentation.html).
## Contact
To report a problem with the PCRE2 library, or to make a feature request, please
use the PCRE2 GitHub issues tracker. There is a mailing list for discussion of
PCRE2 issues and development at pcre2-dev@googlegroups.com, which is where any
announcements will be made. You can browse the
[list archives](https://groups.google.com/g/pcre2-dev).

###############################################################################
# Run the PCRE2 tests using the pcre2test program. The appropriate tests are
# selected, depending on which build-time options were used.
#
# When JIT support is available, all appropriate tests are run with and without
# JIT, unless "-nojit" is given on the command line. There are also two tests
# for JIT-specific features, one to be run when JIT support is available
# (unless "-nojit" is specified), and one when it is not.
#
# Whichever of the 8-, 16- and 32-bit libraries exist are tested. It is also
# possible to select which to test by giving "-8", "-16" or "-32" on the
# command line.
#
# As well as "-nojit", "-8", "-16", and "-32", arguments for this script are
# individual test numbers, ranges of tests such as 3-6 or 3- (meaning 3 to the
# end), or a number preceded by ~ to exclude a test. For example, "3-15 ~10"
# runs tests 3 to 15, excluding test 10, and just "~10" runs all the tests
# except test 10. Whatever order the arguments are in, these tests are always
# run in numerical order.
#
# If no specific tests are selected (which is the case when this script is run
# via 'make check') the default is to run all the numbered tests.
#
# There may also be named (as well as numbered) tests for special purposes. At
# present there is just one, called "heap". This test's output contains the
# sizes of heap frames and frame vectors, which depend on the environment. It
# is therefore not run unless explicitly requested.
#
# Inappropriate tests are automatically skipped (with a comment to say so). For
# example, if JIT support is not compiled, test 16 is skipped, whereas if JIT
# support is compiled, test 15 is skipped.
#
# Other arguments can be one of the words "-valgrind", "-valgrind-log", or
# "-sim" followed by an argument to run cross-compiled executables under a
# simulator, for example:
#
# RunTest 3 -sim "qemu-arm -s 8388608"
#
# For backwards compatibility, -nojit, -valgrind, -valgrind-log, and -sim may
# be given without the leading "-" character.
#
# When PCRE2 is compiled by clang with -fsanitize arguments, some tests need
# very much more stack than normal. In environments where the stack can be
# set at runtime, -bigstack sets a gigantic stack.
#
# There are two special cases where only one argument is allowed:
#
# If the first and only argument is "ebcdic", the script runs the special
# EBCDIC test that can be useful for checking certain EBCDIC features, even
# when run in an ASCII environment. PCRE2 must be built with EBCDIC support for
# this test to be run.
#
# If the script is obeyed as "RunTest list", a list of available tests is
# output, but none of them are run.

@rem
@rem MS Windows batch file to run pcre2test on testfiles with the correct
@rem options. This file must use CRLF linebreaks to function properly,
@rem and requires both pcre2test and pcre2grep.
@rem
@rem ------------------------ HISTORY ----------------------------------
@rem This file was originally contributed to PCRE1 by Ralf Junker, and touched
@rem up by Daniel Richard G. Tests 10-12 added by Philip H.
@rem Philip H also changed test 3 to use "wintest" files.
@rem
@rem Updated by Tom Fortmann to support explicit test numbers on the command
@rem line. Added argument validation and added error reporting.
@rem
@rem Sheri Pierce added logic to skip feature dependent tests
@rem tests 4 5 7 10 12 14 19 22 25 and 26 require Unicode support
@rem 8 requires Unicode and link size 2
@rem 16 requires absence of jit support
@rem 17 requires presence of jit support
@rem Sheri P also added override tests for study and jit testing
@rem Zoltan Herczeg added libpcre16 support
@rem Zoltan Herczeg added libpcre32 support
@rem -------------------------------------------------------------------
@rem
@rem The file was converted for PCRE2 by PH, February 2015.
@rem Updated for new test 14 (moving others up a number), August 2015.
@rem Tidied and updated for new tests 21, 22, 23 by PH, October 2015.
@rem PH added missing "set type" for test 22, April 2016.
@rem PH added copy command for new testbtables file, November 2020
@rem PH caused it to show comparison output when comparison failed, July 2023
@rem PH updated unknown error number in test

# Security policies
## Release security
The PCRE2 project provides source-only releases, with no binaries.
These source releases can be downloaded from the
[GitHub Releases](https://github.com/PCRE2Project/pcre2/releases) page. Each
release file is GPG-signed.
* Releases up to and including 10.44 are signed by Philip Hazel (GPG key:
<kbd>45F68D54BBE23FB3039B46E59766E084FB0F43D8</kbd>)
* Releases from 10.45 onwards will be signed by Nicholas Wilson (GPG key:
<kbd>A95536204A3BB489715231282A98E77EB6F24CA8</kbd>, cross-signed by Philip
Hazel's key for release continuity)
From releases 10.45 onwards, the source code will additionally be provided via
Git checkout of the (GPG-signed) release tag.
Please contact the maintainers for any queries about release integrity or the
project's supply-chain.
## Reporting vulnerabilities
The PCRE2 project prioritises security. We appreciate third-party testing and
security research, and would be grateful if you could responsibly disclose your
findings to us. We will make every effort to acknowledge your contributions.
To report a security issue, please use the GitHub Security Advisory
["Report a Vulnerability"](https://github.com/PCRE2Project/pcre2/security/advisories/new)
tab. (Alternatively, if you prefer you may send a GPG-encrypted email to one of
the maintainers.)
### Timeline
As a very small volunteer team, we cannot guarantee rapid response, but would
aim to respond within 1 week, or perhaps 2 during holidays.
### Response procedure
PCRE2 has never previously made a rapid or embargoed release in response to a
security incident. We would work with security managers from trusted downstream
distributors, such as major Linux distributions, before disclosing the
vulnerability publicly.

#
# This file is free software; the Free Software Foundation

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

Oops!
Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present. This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
Please tell bug-automake@gnu.org about your system, including the value
of your $PATH and any error possibly output before this message. This

Aborting the configuration process, to ensure you take notice of the issue.
You can download and install GNU coreutils to get an 'rm' implementation

# Configuration subroutine to validate and canonicalize a configuration type.
# Supply the specified configuration type as an argument.
# If it is invalid, we print an error message on stderr and exit with code 1.
# Otherwise, we print the canonical config type on stdout and succeed.
# You can get the latest version of this script from:
# https://git.savannah.gnu.org/cgit/config.git/plain/config.sub
# This file is supposed to be the same for all GNU packages
# and recognize all the CPU types, system types and aliases
# that are meaningful with *any* GNU software.
# Each package is responsible for reporting which valid configurations
# it does not support. The user should be able to distinguish
# a failure to support a valid configuration from a meaningless
# configuration.
# The goal of this file is to map all the various variations of a given
# machine specification into a single specification in the form:
# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or in some cases, the newer four-part form:
# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# It is wrong to echo any other type of specification.
# The "shellcheck disable" line above the timestamp inhibits complaints
# about features and limitations of the classic Bourne shell that were
# superseded or lifted in POSIX. However, this script identifies a wide
# variety of pre-POSIX systems that do not have POSIX shells at all, and
# even some reasonably current systems (Solaris 10 as case-in-point) still
# have a pre-POSIX /bin/sh.

## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
## correctly. Breaking it into two sed invocations is a workaround.

Building PCRE2 under VMS
GENERAL
The source of the PCRE2 libraries consists entirely of code written in Standard
C, and so should compile successfully on any system that has a Standard C
compiler and library.
The PCRE2 distribution includes a "configure" file for use by the
configure/make (autotools) build system, as found in many Unix-like
environments. The README file contains information about the options for
"configure".
There is also support for CMake, which some users prefer, especially in Windows
environments, though it can also be run in Unix-like environments. See the
section entitled "Building PCRE2 on Windows with CMake" below.
Versions of src/config.h and src/pcre2.h are distributed in the PCRE2 tarballs
under the names src/config.h.generic and src/pcre2.h.generic. These are
provided for those who build PCRE2 without using "configure" or CMake. If you
use "configure" or CMake, the .generic versions are not used.
GENERIC INSTRUCTIONS FOR THE PCRE2 C LIBRARIES
There are three possible PCRE2 libraries, each handling data with a specific
code unit width: 8, 16, or 32 bits. You can build any combination of them. The
following are generic instructions for building a PCRE2 C library "by hand". If
you are going to use CMake, this section does not apply to you; you can skip
ahead to the CMake section. Note that the settings concerned with 8-bit,
16-bit, and 32-bit code units relate to the type of data string that PCRE2
processes. They are NOT referring to the underlying operating system bit width.
You do not have to do anything special to compile in a 64-bit environment, for
example.
(1) Copy or rename the file src/config.h.generic as src/config.h, and edit the
macro settings that it contains to whatever is appropriate for your
environment. In particular, you can alter the definition of the NEWLINE
macro to specify what character(s) you want to be interpreted as line
terminators by default. You need to #define at least one of
SUPPORT_PCRE2_8, SUPPORT_PCRE2_16, or SUPPORT_PCRE2_32, depending on which
libraries you are going to build. You must set all that apply.
When you subsequently compile any of the PCRE2 modules, you must specify
-DHAVE_CONFIG_H to your compiler so that src/config.h is included in the
sources.
An alternative approach is not to edit src/config.h, but to use -D on the
compiler command line to make any changes that you need to the
configuration options. In this case -DHAVE_CONFIG_H must not be set.
NOTE: There have been occasions when the way in which certain parameters
in src/config.h are used has changed between releases. (In the
configure/make world, this is handled automatically.) When upgrading to a
new release, you are strongly advised to review src/config.h.generic
before re-using what you had previously.
Note also that the src/config.h.generic file is created from a config.h
that was generated by Autotools, which automatically includes settings of
a number of macros that are not actually used by PCRE2 (for example,
HAVE_DLFCN_H).
(2) Copy or rename the file src/pcre2.h.generic as src/pcre2.h.
(3) EITHER:
Copy or rename file src/pcre2_chartables.c.dist as
src/pcre2_chartables.c.
OR:
Compile src/pcre2_dftables.c as a stand-alone program (using
-DHAVE_CONFIG_H if you have set up src/config.h), and then run it with
the single argument "src/pcre2_chartables.c". This generates a set of
standard character tables and writes them to that file. The tables are
generated using the default C locale for your system. If you want to use
a locale that is specified by LC_xxx environment variables, add the -L
option to the pcre2_dftables command. You must use this method if you
are building on a system that uses EBCDIC code.
The tables in src/pcre2_chartables.c are defaults. The caller of PCRE2 can
specify alternative tables at run time.
(4) For a library that supports 8-bit code units in the character strings that
it processes, compile the following source files from the src directory,
setting -DPCRE2_CODE_UNIT_WIDTH=8 as a compiler option. Also set
-DHAVE_CONFIG_H if you have set up src/config.h with your configuration,
or else use other -D settings to change the configuration as required.
pcre2_auto_possess.c
pcre2_chkdint.c
pcre2_chartables.c
pcre2_compile.c
pcre2_compile_class.c
pcre2_config.c
pcre2_context.c
pcre2_convert.c
pcre2_dfa_match.c
pcre2_error.c
pcre2_extuni.c
pcre2_find_bracket.c
pcre2_jit_compile.c
pcre2_maketables.c
pcre2_match.c
pcre2_match_data.c
pcre2_newline.c
pcre2_ord2utf.c
pcre2_pattern_info.c
pcre2_script_run.c
pcre2_serialize.c
pcre2_string_utils.c
pcre2_study.c
pcre2_substitute.c
pcre2_substring.c
pcre2_tables.c
pcre2_ucd.c
pcre2_valid_utf.c
pcre2_xclass.c
Make sure that you include -I. in the compiler command (or equivalent for
an unusual compiler) so that all included PCRE2 header files are first
sought in the src directory under the current directory. Otherwise you run
the risk of picking up a previously-installed file from somewhere else.
Note that you must compile pcre2_jit_compile.c, even if you have not
defined SUPPORT_JIT in src/config.h, because when JIT support is not
configured, dummy functions are compiled. When JIT support IS configured,
pcre2_jit_compile.c #includes other files from the sljit dependency,
all of whose names begin with "sljit". It also #includes
src/pcre2_jit_match.c and src/pcre2_jit_misc.c, so you should not compile
those yourself.
Note also that the pcre2_fuzzsupport.c file contains special code that is
useful to those who want to run fuzzing tests on the PCRE2 library. Unless
you are doing that, you can ignore it.
(5) Now link all the compiled code into an object library in whichever form
your system keeps such libraries. This is the PCRE2 C 8-bit library,
typically called something like libpcre2-8. If your system has static and
shared libraries, you may have to do this once for each type.
(6) If you want to build a library that supports 16-bit or 32-bit code units,
set 16 or 32 as the value of -DPCRE2_CODE_UNIT_WIDTH when obeying step 4
above. If you want to build more than one PCRE2 library, repeat steps 4
and 5 as necessary.
(7) If you want to build the POSIX wrapper functions (which apply only to the
8-bit library), ensure that you have the src/pcre2posix.h file and then
compile src/pcre2posix.c. Link the result (on its own) as the pcre2posix
library. If targeting a DLL in Windows, make sure to include
-DPCRE2POSIX_SHARED with your compiler flags.
(8) The pcre2test program can be linked with any combination of the 8-bit,
16-bit and 32-bit libraries (depending on what you specfied in
src/config.h) . Compile src/pcre2test.c; don't forget -DHAVE_CONFIG_H if
necessary, but do NOT define PCRE2_CODE_UNIT_WIDTH. Then link with the
appropriate library/ies. If you compiled an 8-bit library, pcre2test also
needs the pcre2posix wrapper library.
(9) Run pcre2test on the testinput files in the testdata directory, and check
that the output matches the corresponding testoutput files. There are
comments about what each test does in the section entitled "Testing PCRE2"
in the README file. If you compiled more than one of the 8-bit, 16-bit and
32-bit libraries, you need to run pcre2test with the -16 option to do
16-bit tests and with the -32 option to do 32-bit tests.
Some tests are relevant only when certain build-time options are selected.
For example, test 4 is for Unicode support, and will not run if you have
built PCRE2 without it. See the comments at the start of each testinput
file. If you have a suitable Unix-like shell, the RunTest script will run
the appropriate tests for you. The command "RunTest list" will output a
list of all the tests.
Note that the supplied files are in Unix format, with just LF characters
as line terminators. You may need to edit them to change this if your
system uses a different convention.
(10) If you have built PCRE2 with SUPPORT_JIT, the JIT features can be tested
by running pcre2test with the -jit option. This is done automatically by
the RunTest script. You might also like to build and run the freestanding
JIT test program, src/pcre2_jit_test.c.
(11) The pcre2test program tests the POSIX wrapper library, but there is also a
freestanding test program in src/pcre2posix_test.c. It must be linked with
both the pcre2posix library and the 8-bit PCRE2 library.
(12) If you want to use the pcre2grep command, compile and link
src/pcre2grep.c; it uses only the 8-bit PCRE2 library (it does not need
the pcre2posix library). If you have built the PCRE2 library with JIT
support by defining SUPPORT_JIT in src/config.h, you can also define
SUPPORT_PCRE2GREP_JIT, which causes pcre2grep to make use of JIT (unless
it is run with --no-jit). If you define SUPPORT_PCRE2GREP_JIT without
defining SUPPORT_JIT, pcre2grep does not try to make use of JIT.
STACK SIZE IN WINDOWS ENVIRONMENTS
Prior to release 10.30 the default system stack size of 1MiB in some Windows
environments caused issues with some tests. This should no longer be the case
for 10.30 and later releases.
LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
If you want to statically link a program against a PCRE2 library in the form of
a non-dll .a file, you must define PCRE2_STATIC before including src/pcre2.h.
CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
It is possible to compile programs to use different calling conventions using
MSVC. Search the web for "calling conventions" for more information. To make it
easier to change the calling convention for the exported functions in a
PCRE2 library, the macro PCRE2_CALL_CONVENTION is present in all the external
definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
not set, it defaults to empty; the default calling convention is then used
(which is what is wanted most of the time).
COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE2 ON WINDOWS WITH CMAKE")
There are two ways of building PCRE2 using the "configure, make, make install"
paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
the same thing; they are completely different from each other. There is also
support for building using CMake, which some users find a more straightforward
way of building PCRE2 under Windows.
The MinGW home page (http://www.mingw.org/) says this:
MinGW: A collection of freely available and freely distributable Windows
specific header files and import libraries combined with GNU toolsets that
allow one to produce native Windows programs that do not rely on any
3rd-party C runtime DLLs.
The Cygwin home page (http://www.cygwin.com/) says this:
Cygwin is a Linux-like environment for Windows. It consists of two parts:
. A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
substantial Linux API functionality
. A collection of tools which provide Linux look and feel.
On both MinGW and Cygwin, PCRE2 should build correctly using:
./configure && make && make install
This should create two libraries called libpcre2-8 and libpcre2-posix. These
are independent libraries: when you link with libpcre2-posix you must also link
with libpcre2-8, which contains the basic functions.
Using Cygwin's compiler generates libraries and executables that depend on
cygwin1.dll. If a library that is generated this way is distributed,
cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
licence, this forces not only PCRE2 to be under the GPL, but also the entire
application. A distributor who wants to keep their own code proprietary must
purchase an appropriate Cygwin licence.
MinGW has no such restrictions. The MinGW compiler generates a library or
executable that can run standalone on Windows without any third party dll or
licensing issues.
But there is more complication:
If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
gcc and MinGW's gcc). So, a user can:
. Build native binaries by using MinGW or by getting Cygwin and using
-mno-cygwin.
. Build binaries that depend on cygwin1.dll by using Cygwin with the normal
compiler flags.
The test files that are supplied with PCRE2 are in UNIX format, with LF
characters as line terminators. Unless your PCRE2 library uses a default
newline option that includes LF as a valid newline, it may be necessary to
change the line terminators in the test files to get some of the tests to work.
BUILDING PCRE2 ON WINDOWS WITH CMAKE
CMake is an alternative configuration facility that can be used instead of
"configure". CMake creates project files (make files, solution files, etc.)
tailored to numerous development environments, including Visual Studio,
Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no
spaces in the names for your CMake installation and your PCRE2 source and build
directories.
If you are using CMake and encounter errors, deleting the CMake cache and
restarting from a fresh build may fix the error. In the CMake GUI, the cache can
be deleted by selecting "File > Delete Cache"; or the folder "CMakeCache" can
be deleted.
1. Install the latest CMake version available from http://www.cmake.org/, and
ensure that cmake\bin is on your path.
2. Unzip (retaining folder structure) the PCRE2 source tree into a source
directory such as C:\pcre2. You should ensure your local date and time
is not earlier than the file dates in your source dir if the release is
very new.
3. Create a new, empty build directory, preferably a subdirectory of the
source dir. For example, C:\pcre2\pcre2-xx\build.
4. Run CMake.
- Using the CLI, simply run `cmake ..` inside the `build/` directory. You can
use the `ccmake` ncurses GUI to select and configure PCRE2 features.
- Using the CMake GUI:
a) Run cmake-gui from the Shell environment of your build tool, for
example, Msys for Msys/MinGW or Visual Studio Command Prompt for
VC/VC++.
b) Enter C:\pcre2\pcre2-xx and C:\pcre2\pcre2-xx\build for the source and
build directories, respectively.
c) Press the "Configure" button.
d) Select the particular IDE / build tool that you are using (Visual
Studio, MSYS makefiles, MinGW makefiles, etc.)
e) The GUI will then list several configuration options. This is where
you can disable Unicode support or select other PCRE2 optional features.
f) Press "Configure" again. The adjacent "Generate" button should now be
active.
g) Press "Generate".
5. The build directory should now contain a usable build system, be it a
solution file for Visual Studio, makefiles for MinGW, etc. Exit from
cmake-gui and use the generated build system with your compiler or IDE.
E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE2
solution, select the desired configuration (Debug, or Release, etc.) and
build the ALL_BUILD project.
Regardless of build system used, `cmake --build .` will build it.
6. If during configuration with cmake-gui you've elected to build the test
programs, you can execute them by building the test project. E.g., for
MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The
most recent build configuration is targeted by the tests. A summary of
test results is presented. Complete test output is subsequently
available for review in Testing\Temporary under your build dir.
Regardless of build system used, `ctest` will run the tests.
BUILDING PCRE2 ON WINDOWS WITH VISUAL STUDIO
The code currently cannot be compiled without an inttypes.h header, which is
available only with Visual Studio 2013 or newer. However, this portable and
permissively-licensed implementation of the stdint.h header could be used as an
alternative:
http://www.azillionmonkeys.com/qed/pstdint.h
Just rename it and drop it into the top level of the build tree.
TESTING WITH RUNTEST.BAT
If configured with CMake, building the test project ("make test" or building
ALL_TESTS in Visual Studio) creates (and runs) pcre2_test.bat (and depending
on your configuration options, possibly other test programs) in the build
directory. The pcre2_test.bat script runs RunTest.bat with correct source and
exe paths.
For manual testing with RunTest.bat, provided the build dir is a subdirectory
of the source directory: Open command shell window. Chdir to the location
of your pcre2test.exe and pcre2grep.exe programs. Call RunTest.bat with
"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate.
To run only a particular test with RunTest.Bat provide a test number argument.
Otherwise:
1. Copy RunTest.bat into the directory where pcre2test.exe and pcre2grep.exe
have been created.
2. Edit RunTest.bat to identify the full or relative location of
the pcre2 source (wherein which the testdata folder resides), e.g.:
set srcdir=C:\pcre2\pcre2-10.00
3. In a Windows command environment, chdir to the location of your bat and
exe programs.
4. Run RunTest.bat. Test outputs will automatically be compared to expected
results, and discrepancies will be identified in the console output.
To independently test the just-in-time compiler, run pcre2_jit_test.exe.
BUILDING PCRE2 ON NATIVE Z/OS AND Z/VM
z/OS and z/VM are operating systems for mainframe computers, produced by IBM.
The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and
applications can be supported through UNIX System Services, and in such an
environment it should be possible to build PCRE2 in the same way as in other
systems, with the EBCDIC related configuration settings, but it is not known if
anybody has tried this.
In native z/OS (without UNIX System Services) and in z/VM, special ports are
required. For details, please see file 939 on this web site:
http://www.cbttape.org
Everything in that location, source and executable, is in EBCDIC and native
z/OS file formats. The port provides an API for LE languages such as COBOL and
for the z/OS and z/VM versions of the Rexx languages.
BUILDING PCRE2 UNDER VMS
Alexey Chuphin has contributed some auxiliary files for building PCRE2 under
OpenVMS. They are in the "vms" directory in the distribution tarball. Please
read the file called vms/openvms_readme.txt. The pcre2test and pcre2grep
programs contain some VMS-specific code.

README file for PCRE2 (Perl-compatible regular expression library)
------------------------------------------------------------------
PCRE2 is a re-working of the original PCRE1 library to provide an entirely new
API. Since its initial release in 2015, there has been further development of
the code and it now differs from PCRE1 in more than just the API. There are new
features, and the internals have been improved. The original PCRE1 library is
now obsolete and no longer maintained. The latest release of PCRE2 is available
in .tar.gz, tar.bz2, or .zip form from this GitHub repository:
https://github.com/PCRE2Project/pcre2/releases
There is a mailing list for discussion about the development of PCRE2 at
pcre2-dev@googlegroups.com. You can subscribe by sending an email to
pcre2-dev+subscribe@googlegroups.com.

The PCRE2 APIs
--------------
PCRE2 is written in C, and it has its own API. There are three sets of
functions, one for the 8-bit library, which processes strings of bytes, one for
the 16-bit library, which processes strings of 16-bit values, and one for the
32-bit library, which processes strings of 32-bit values. Unlike PCRE1, there
are no C++ wrappers.
The distribution does contain a set of C wrapper functions for the 8-bit
library that are based on the POSIX regular expression API (see the pcre2posix
man page). These are built into a library called libpcre2-posix. Note that this
just provides a POSIX calling interface to PCRE2; the regular expressions
themselves still follow Perl syntax and semantics. The POSIX API is restricted,
and does not give full access to all of PCRE2's facilities.
The header file for the POSIX-style functions is called pcre2posix.h. The
official POSIX name is regex.h, but I did not want to risk possible problems
with existing files of that name by distributing it that way. To use PCRE2 with
an existing program that uses the POSIX API, pcre2posix.h will have to be
renamed or pointed at by a link (or the program modified, of course). See the
pcre2posix documentation for more details.
Documentation for PCRE2
-----------------------
If you install PCRE2 in the normal way on a Unix-like system, you will end up
with a set of man pages whose names all start with "pcre2". The one that is
just called "pcre2" lists all the others. In addition to these man pages, the
PCRE2 documentation is supplied in two other forms:
1. There are files called doc/pcre2.txt, doc/pcre2grep.txt, and
doc/pcre2test.txt in the source distribution. The first of these is a
concatenation of the text forms of all the section 3 man pages except the
listing of pcre2demo.c and those that summarize individual functions. The
other two are the text forms of the section 1 man pages for the pcre2grep
and pcre2test commands. These text forms are provided for ease of scanning
with text editors or similar tools. They are installed in
<prefix>/share/doc/pcre2, where <prefix> is the installation prefix
(defaulting to /usr/local).
2. A set of files containing all the documentation in HTML form, hyperlinked
in various ways, and rooted in a file called index.html, is distributed in
doc/html and installed in <prefix>/share/doc/pcre2/html.
Building PCRE2 on non-Unix-like systems
---------------------------------------
For a non-Unix-like system, please read the file NON-AUTOTOOLS-BUILD, though if
your system supports the use of "configure" and "make" you may be able to build
PCRE2 using autotools in the same way as for many Unix-like systems.
PCRE2 can also be configured using CMake, which can be run in various ways
(command line, GUI, etc). This creates Makefiles, solution files, etc. The file
NON-AUTOTOOLS-BUILD has information about CMake.
PCRE2 has been compiled on many different operating systems. It should be
straightforward to build PCRE2 on any system that has a Standard C compiler and
library, because it uses only Standard C functions.
Building PCRE2 without using autotools
--------------------------------------
The use of autotools (in particular, libtool) is problematic in some
environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD
file for ways of building PCRE2 without using autotools.
Building PCRE2 using autotools
------------------------------
The following instructions assume the use of the widely used "configure; make;
make install" (autotools) process.
If you have downloaded and unpacked a PCRE2 release tarball, run the
"configure" command from the PCRE2 directory, with your current directory set
to the directory where you want the files to be created. This command is a
standard GNU "autoconf" configuration script, for which generic instructions
are supplied in the file INSTALL.
The files in the GitHub repository do not contain "configure". If you have
downloaded the PCRE2 source files from GitHub, before you can run "configure"
you must run the shell script called autogen.sh. This runs a number of
autotools to create a "configure" script (you must of course have the autotools
commands installed in order to do this).
Most commonly, people build PCRE2 within its own distribution directory, and in
this case, on many systems, just running "./configure" is sufficient. However,
the usual methods of changing standard defaults are available. For example:
CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
This command specifies that the C compiler should be run with the flags '-O2
-Wall' instead of the default, and that "make install" should install PCRE2
under /opt/local instead of the default /usr/local.
If you want to build in a different directory, just run "configure" with that
directory as current. For example, suppose you have unpacked the PCRE2 source
into /source/pcre2/pcre2-xxx, but you want to build it in
/build/pcre2/pcre2-xxx:
cd /build/pcre2/pcre2-xxx
/source/pcre2/pcre2-xxx/configure
PCRE2 is written in C and is normally compiled as a C library. However, it is
possible to build it as a C++ library, though the provided building apparatus
does not have any features to support this.
There are some optional features that can be included or omitted from the PCRE2
library. They are also documented in the pcre2build man page.
. By default, both shared and static libraries are built. You can change this
by adding one of these options to the "configure" command:
--disable-shared
--disable-static
Setting --disable-shared ensures that PCRE2 libraries are built as static
libraries. The binaries that are then created as part of the build process
(for example, pcre2test and pcre2grep) are linked statically with one or more
PCRE2 libraries, but may also be dynamically linked with other libraries such
as libc. If you want these binaries to be fully statically linked, you can
set LDFLAGS like this:
LDFLAGS=--static ./configure --disable-shared
Note the two hyphens in --static. Of course, this works only if static
versions of all the relevant libraries are available for linking. See also
"Shared libraries" below.
. By default, only the 8-bit library is built. If you add --enable-pcre2-16 to
the "configure" command, the 16-bit library is also built. If you add
--enable-pcre2-32 to the "configure" command, the 32-bit library is also
built. If you want only the 16-bit or 32-bit library, use --disable-pcre2-8
to disable building the 8-bit library.
. If you want to include support for just-in-time (JIT) compiling, which can
give large performance improvements on certain platforms, add --enable-jit to
the "configure" command. This support is available only for certain hardware
architectures. If you try to enable it on an unsupported architecture, there
will be a compile time error. If in doubt, use --enable-jit=auto, which
enables JIT only if the current hardware is supported.
. If you are enabling JIT under SELinux environment you may also want to add
--enable-jit-sealloc, which enables the use of an executable memory allocator
that is compatible with SELinux. Warning: this allocator is experimental!
It does not support fork() operation and may crash when no disk space is
available. This option has no effect if JIT is disabled.
. If you do not want to make use of the default support for UTF-8 Unicode
character strings in the 8-bit library, UTF-16 Unicode character strings in
the 16-bit library, or UTF-32 Unicode character strings in the 32-bit
library, you can add --disable-unicode to the "configure" command. This
reduces the size of the libraries. It is not possible to configure one
library with Unicode support, and another without, in the same configuration.
It is also not possible to use --enable-ebcdic (see below) with Unicode
support, so if this option is set, you must also use --disable-unicode.
When Unicode support is available, the use of a UTF encoding still has to be
enabled by setting the PCRE2_UTF option at run time or starting a pattern
with (*UTF). When PCRE2 is compiled with Unicode support, its input can only
either be ASCII or UTF-8/16/32, even when running on EBCDIC platforms.
As well as supporting UTF strings, Unicode support includes support for the
\P, \p, and \X sequences that recognize Unicode character properties.
However, only a subset of Unicode properties are supported; see the
pcre2pattern man page for details. Escape sequences such as \d and \w in
patterns do not by default make use of Unicode properties, but can be made to
do so by setting the PCRE2_UCP option or starting a pattern with (*UCP).
. You can build PCRE2 to recognize either CR or LF or the sequence CRLF, or any
of the preceding, or any of the Unicode newline sequences, or the NUL (zero)
character as indicating the end of a line. Whatever you specify at build time
is the default; the caller of PCRE2 can change the selection at run time. The
default newline indicator is a single LF character (the Unix standard). You
can specify the default newline indicator by adding --enable-newline-is-cr,
--enable-newline-is-lf, --enable-newline-is-crlf,
--enable-newline-is-anycrlf, --enable-newline-is-any, or
--enable-newline-is-nul to the "configure" command, respectively.
. By default, the sequence \R in a pattern matches any Unicode line ending
sequence. This is independent of the option specifying what PCRE2 considers
to be the end of a line (see above). However, the caller of PCRE2 can
restrict \R to match only CR, LF, or CRLF. You can make this the default by
adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").
. In a pattern, the escape sequence \C matches a single code unit, even in a
UTF mode. This can be dangerous because it breaks up multi-code-unit
characters. You can build PCRE2 with the use of \C permanently locked out by
adding --enable-never-backslash-C (note the upper case C) to the "configure"
command. When \C is allowed by the library, individual applications can lock
it out by calling pcre2_compile() with the PCRE2_NEVER_BACKSLASH_C option.
. PCRE2 has a counter that limits the depth of nesting of parentheses in a
pattern. This limits the amount of system stack that a pattern uses when it
is compiled. The default is 250, but you can change it by setting, for
example,
--with-parens-nest-limit=500
. PCRE2 has a counter that can be set to limit the amount of computing resource
it uses when matching a pattern. If the limit is exceeded during a match, the
match fails. The default is ten million. You can change the default by
setting, for example,
--with-match-limit=500000
on the "configure" command. This is just the default; individual calls to
pcre2_match() or pcre2_dfa_match() can supply their own value. There is more
discussion in the pcre2api man page (search for pcre2_set_match_limit).
. There is a separate counter that limits the depth of nested backtracking
(pcre2_match()) or nested function calls (pcre2_dfa_match()) during a
matching process, which indirectly limits the amount of heap memory that is
used, and in the case of pcre2_dfa_match() the amount of stack as well. This
counter also has a default of ten million, which is essentially "unlimited".
You can change the default by setting, for example,
--with-match-limit-depth=5000
There is more discussion in the pcre2api man page (search for
pcre2_set_depth_limit).
. You can also set an explicit limit on the amount of heap memory used by
the pcre2_match() and pcre2_dfa_match() interpreters:
--with-heap-limit=500
The units are kibibytes (units of 1024 bytes). This limit does not apply when
the JIT optimization (which has its own memory control features) is used.
There is more discussion on the pcre2api man page (search for
pcre2_set_heap_limit).
. In the 8-bit library, the default maximum compiled pattern size is around
64 kibibytes. You can increase this by adding --with-link-size=3 to the
"configure" command. PCRE2 then uses three bytes instead of two for offsets
to different parts of the compiled pattern. In the 16-bit library,
--with-link-size=3 is the same as --with-link-size=4, which (in both
libraries) uses four-byte offsets. Increasing the internal link size reduces
performance in the 8-bit and 16-bit libraries. In the 32-bit library, the
link size setting is ignored, as 4-byte offsets are always used.
. Lookbehind assertions in which one or more branches can match a variable
number of characters are supported only if there is a maximum matching length
for each top-level branch. There is a limit to this maximum that defaults to
255 characters. You can alter this default by a setting such as
--with-max-varlookbehind=100
The limit can be changed at runtime by calling pcre2_set_max_varlookbehind().
Lookbehind assertions in which every branch matches a fixed number of
characters (not necessarily all the same) are not constrained by this limit.
. For speed, PCRE2 uses four tables for manipulating and identifying characters
whose code point values are less than 256. By default, it uses a set of
tables for ASCII encoding that is part of the distribution. If you specify
--enable-rebuild-chartables
a program called pcre2_dftables is compiled and run in the default C locale
when you obey "make". It builds a source file called pcre2_chartables.c. If
you do not specify this option, pcre2_chartables.c is created as a copy of
pcre2_chartables.c.dist. See "Character tables" below for further
information.
. It is possible to compile PCRE2 for use on systems that use EBCDIC as their
character code (as opposed to ASCII/Unicode) by specifying
--enable-ebcdic --disable-unicode
This automatically implies --enable-rebuild-chartables (see above). However,
when PCRE2 is built this way, it always operates in EBCDIC. It cannot support
both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25,
which specifies that the code value for the EBCDIC NL character is 0x25
instead of the default 0x15.
. If you specify --enable-debug, additional debugging code is included in the
build. This option is intended for use by the PCRE2 maintainers.
. In environments where valgrind is installed, if you specify
--enable-valgrind
PCRE2 will use valgrind annotations to mark certain memory regions as
unaddressable. This allows it to detect invalid memory accesses, and is
mostly useful for debugging PCRE2 itself.
. In environments where the gcc compiler is used and lcov is installed, if you
specify
--enable-coverage
the build process implements a code coverage report for the test suite. The
report is generated by running "make coverage". If ccache is installed on
your system, it must be disabled when building PCRE2 for coverage reporting.
You can do this by setting the environment variable CCACHE_DISABLE=1 before
running "make" to build PCRE2. There is more information about coverage
reporting in the "pcre2build" documentation.
. When JIT support is enabled, pcre2grep automatically makes use of it, unless
you add --disable-pcre2grep-jit to the "configure" command.
. There is support for calling external programs during matching in the
pcre2grep command, using PCRE2's callout facility with string arguments. This
support can be disabled by adding --disable-pcre2grep-callout to the
"configure" command. There are two kinds of callout: one that generates
output from inbuilt code, and another that calls an external program. The
latter has special support for Windows and VMS; otherwise it assumes the
existence of the fork() function. This facility can be disabled by adding
--disable-pcre2grep-callout-fork to the "configure" command.
. The pcre2grep program currently supports only 8-bit data files, and so
requires the 8-bit PCRE2 library. It is possible to compile pcre2grep to use
libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by
specifying one or both of
--enable-pcre2grep-libz
--enable-pcre2grep-libbz2
Of course, the relevant libraries must be installed on your system.
. The default starting size (in bytes) of the internal buffer used by pcre2grep
can be set by, for example:
--with-pcre2grep-bufsize=51200
The value must be a plain integer. The default is 20480. The amount of memory
used by pcre2grep is actually three times this number, to allow for "before"
and "after" lines. If very long lines are encountered, the buffer is
automatically enlarged, up to a fixed maximum size.
. The default maximum size of pcre2grep's internal buffer can be set by, for
example:
--with-pcre2grep-max-bufsize=2097152
The default is either 1048576 or the value of --with-pcre2grep-bufsize,
whichever is the larger.
. It is possible to compile pcre2test so that it links with the libreadline
or libedit libraries, by specifying, respectively,
--enable-pcre2test-libreadline or --enable-pcre2test-libedit
If this is done, when pcre2test's input is from a terminal, it reads it using
the readline() function. This provides line-editing and history facilities.
Note that libreadline is GPL-licensed, so if you distribute a binary of
pcre2test linked in this way, there may be licensing issues. These can be
avoided by linking with libedit (which has a BSD licence) instead.
Enabling libreadline causes the -lreadline option to be added to the
pcre2test build. In many operating environments with a system-installed
readline library this is sufficient. However, in some environments (e.g. if
an unmodified distribution version of readline is in use), it may be
necessary to specify something like LIBS="-lncurses" as well. This is
because, to quote the readline INSTALL, "Readline uses the termcap functions,
but does not link with the termcap or curses library itself, allowing
applications which link with readline the option to choose an appropriate
library." If you get error messages about missing functions tgetstr, tgetent,
tputs, tgetflag, or tgoto, this is the problem, and linking with the ncurses
library should fix it.
. The C99 standard defines formatting modifiers z and t for size_t and
ptrdiff_t values, respectively. By default, PCRE2 uses these modifiers in
environments other than Microsoft Visual Studio versions earlier than 2013
when __STDC_VERSION__ is defined and has a value greater than or equal to
199901L (indicating C99). However, there is at least one environment that
claims to be C99 but does not support these modifiers. If
--disable-percent-zt is specified, no use is made of the z or t modifiers.
Instead of %td or %zu, %lu is used, with a cast for size_t values.
. There is a special option called --enable-fuzz-support for use by people who
want to run fuzzing tests on PCRE2. If set, it causes an extra library
called libpcre2-fuzzsupport.a to be built, but not installed. This contains
a single function called LLVMFuzzerTestOneInput() whose arguments are a
pointer to a string and the length of the string. When called, this function
tries to compile the string as a pattern, and if that succeeds, to match
it. This is done both with no options and with some random options bits that
are generated from the string. Setting --enable-fuzz-support also causes an
executable called pcre2fuzzcheck-{8,16,32} to be created. This is normally
run under valgrind or used when PCRE2 is compiled with address sanitizing
enabled. It calls the fuzzing function and outputs information about what it
is doing. The input strings are specified by arguments: if an argument
starts with "=" the rest of it is a literal input string. Otherwise, it is
assumed to be a file name, and the contents of the file are the test string.
. Releases before 10.30 could be compiled with --disable-stack-for-recursion,
which caused pcre2_match() to use individual blocks on the heap for
backtracking instead of recursive function calls (which use the stack). This
is now obsolete because pcre2_match() was refactored always to use the heap
(in a much more efficient way than before). This option is retained for
backwards compatibility, but has no effect other than to output a warning.
The "configure" script builds the following files for the basic C library:
. Makefile the makefile that builds the library
. src/config.h build-time configuration options for the library
. src/pcre2.h the public PCRE2 header file
. pcre2-config script that shows the building settings such as CFLAGS
that were set for "configure"
. libpcre2-8.pc )
. libpcre2-16.pc ) data for the pkg-config command
. libpcre2-32.pc )
. libpcre2-posix.pc )
. libtool script that builds shared and/or static libraries
Versions of config.h and pcre2.h are distributed in the src directory of PCRE2
tarballs under the names config.h.generic and pcre2.h.generic. These are
provided for those who have to build PCRE2 without using "configure" or CMake.
If you use "configure" or CMake, the .generic versions are not used.
The "configure" script also creates config.status, which is an executable
script that can be run to recreate the configuration, and config.log, which
contains compiler output from tests that "configure" runs.
Once "configure" has run, you can run "make". This builds whichever of the
libraries libpcre2-8, libpcre2-16 and libpcre2-32 are configured, and a test
program called pcre2test. If you enabled JIT support with --enable-jit, another
test program called pcre2_jit_test is built as well. If the 8-bit library is
built, libpcre2-posix, pcre2posix_test, and the pcre2grep command are also
built. Running "make" with the -j option may speed up compilation on
multiprocessor systems.
The command "make check" runs all the appropriate tests. Details of the PCRE2
tests are given below in a separate section of this document. The -j option of
"make" can also be used when running the tests.
You can use "make install" to install PCRE2 into live directories on your
system. The following are installed (file names are all relative to the
<prefix> that is set when "configure" is run):
Commands (bin):
pcre2test
pcre2grep (if 8-bit support is enabled)
pcre2-config
Libraries (lib):

If you want to remove PCRE2 from your system, you can run "make uninstall".
This removes all the files that "make install" installed. However, it does not
remove any directories, because these are often shared with other programs.
Retrieving configuration information
------------------------------------
Running "make install" installs the command pcre2-config, which can be used to
recall information about the PCRE2 configuration and installation. For example:
pcre2-config --version
prints the version number, and
pcre2-config --libs8
outputs information about where the 8-bit library is installed. This command
can be included in makefiles for programs that use PCRE2, saving the programmer
from having to remember too many details. Run pcre2-config with no arguments to
obtain a list of possible arguments.
The pkg-config command is another system for saving and retrieving information
about installed libraries. Instead of separate commands for each library, a
single command is used. For example:
pkg-config --libs libpcre2-16
The data is held in *.pc files that are installed in a directory called
<prefix>/lib/pkgconfig.
Shared libraries
----------------
The default distribution builds PCRE2 as shared libraries and static libraries,
as long as the operating system supports shared libraries. Shared library
support relies on the "libtool" script which is built as part of the
"configure" process.
The libtool script is used to compile and link both shared and static
libraries. They are placed in a subdirectory called .libs when they are newly
built. The programs pcre2test and pcre2grep are built to use these uninstalled
libraries (by means of wrapper scripts in the case of shared libraries). When
you use "make install" to install shared libraries, pcre2grep and pcre2test are
automatically re-built to use the newly installed shared libraries before being
installed themselves. However, the versions left in the build directory still
use the uninstalled libraries.
To build PCRE2 using static libraries only you must use --disable-shared when
configuring it. For example:
./configure --prefix=/usr/gnu --disable-shared
Then run "make" in the usual way. Similarly, you can use --disable-static to
build only shared libraries. Note, however, that when you build only static
libraries, binary programs such as pcre2test and pcre2grep may still be
dynamically linked with other libraries (for example, libc) unless you set
LDFLAGS to --static when running "configure".
Cross-compiling using autotools
-------------------------------
You can specify CC and CFLAGS in the normal way to the "configure" command, in
order to cross-compile PCRE2 for some other host. However, you should NOT
specify --enable-rebuild-chartables, because if you do, the pcre2_dftables.c
source file is compiled and run on the local host, in order to generate the
inbuilt character tables (the pcre2_chartables.c file). This will probably not
work, because pcre2_dftables.c needs to be compiled with the local compiler,
not the cross compiler.
When --enable-rebuild-chartables is not specified, pcre2_chartables.c is
created by making a copy of pcre2_chartables.c.dist, which is a default set of
tables that assumes ASCII code. Cross-compiling with the default tables should
not be a problem.
If you need to modify the character tables when cross-compiling, you should
move pcre2_chartables.c.dist out of the way, then compile pcre2_dftables.c by
hand and run it on the local host to make a new version of
pcre2_chartables.c.dist. See the pcre2build section "Creating character tables
at build time" for more details.
Making new tarballs
-------------------
The command "make dist" creates three PCRE2 tarballs, in tar.gz, tar.bz2, and
zip formats. The command "make distcheck" does the same, but then does a trial
build of the new distribution to ensure that it works.
If you have modified any of the man page sources in the doc directory, you
should first run the maint/PrepareRelease script before making a distribution.
This script creates the .txt and HTML forms of the documentation from the man
pages.
Testing PCRE2
-------------
To test the basic PCRE2 library on a Unix-like system, run the RunTest script.
There is another script called RunGrepTest that tests the pcre2grep command.
When the 8-bit library is built, a test program for the POSIX wrapper, called
pcre2posix_test, is compiled, and when JIT support is enabled, a test program
called pcre2_jit_test is built. The scripts and the program tests are all run
when you obey "make check". For other environments, see the instructions in
NON-AUTOTOOLS-BUILD.
The RunTest script runs the pcre2test test program (which is documented in its
own man page) on each of the relevant testinput files in the testdata
directory, and compares the output with the contents of the corresponding
testoutput files. RunTest uses a file called testtry to hold the main output
from pcre2test. Other files whose names begin with "test" are used as working
files in some tests.
Some tests are relevant only when certain build-time options were selected. For
example, the tests for UTF-8/16/32 features are run only when Unicode support
is available. RunTest outputs a comment when it skips a test.
Many (but not all) of the tests that are not skipped are run twice if JIT
support is available. On the second run, JIT compilation is forced. This
testing can be suppressed by putting "-nojit" on the RunTest command line.
The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit
libraries that are enabled. If you want to run just one set of tests, call
RunTest with either the -8, -16 or -32 option.
If valgrind is installed, you can run the tests under it by putting "-valgrind"
on the RunTest command line. To run pcre2test on just one or more specific test
files, give their numbers as arguments to RunTest, for example:
RunTest 2 7 11
You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the
end), or a number preceded by ~ to exclude a test. For example:
Runtest 3-15 ~10
This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests
except test 13. Whatever order the arguments are in, the tests are always run
in numerical order.
You can also call RunTest with the single argument "list" to cause it to output
a list of tests.
The test sequence starts with "test 0", which is a special test that has no
input file, and whose output is not checked. This is because it will be
different on different hardware and with different configurations. The test
exists in order to exercise some of pcre2test's code that would not otherwise
be run.
Tests 1 and 2 can always be run, as they expect only plain text strings (not
UTF) and make no use of Unicode properties. The first test file can be fed
directly into the perltest.sh script to check that Perl gives the same results.
The only difference you should see is in the first few lines, where the Perl
version is given instead of the PCRE2 version. The second set of tests check
auxiliary functions, error detection, and run-time flags that are specific to
PCRE2. It also uses the debugging flags to check some of the internals of
pcre2_compile().
If you build PCRE2 with a locale setting that is not the standard C locale, the
character tables may be different (see next paragraph). In some cases, this may
cause failures in the second set of tests. For example, in a locale where the
isprint() function yields TRUE for characters in the range 128-255, the use of
[:isascii:] inside a character class defines a different set of characters, and
this shows up in this test as a difference in the compiled code, which is being
listed for checking. For example, where the comparison test output contains
[\x00-\x7f] the test might contain [\x00-\xff], and similarly in some other
cases. This is not a bug in PCRE2.
Test 3 checks pcre2_maketables(), the facility for building a set of character
tables for a specific locale and using them instead of the default tables. The
script uses the "locale" command to check for the availability of the "fr_FR",
"french", or "fr" locale, and uses the first one that it finds. If the "locale"
command fails, or if its output doesn't include "fr_FR", "french", or "fr" in
the list of available locales, the third test cannot be run, and a comment is
output to say why. If running this test produces an error like this:
** Failed to set locale "fr_FR"
it means that the given locale is not available on your system, despite being
listed by "locale". This does not mean that PCRE2 is broken. There are three
alternative output files for the third test, because three different versions
of the French locale have been encountered. The test passes if its output
matches any one of them.
Tests 4 and 5 check UTF and Unicode property support, test 4 being compatible
with the perltest.sh script, and test 5 checking PCRE2-specific things.
Tests 6 and 7 check the pcre2_dfa_match() alternative matching function, in
non-UTF mode and UTF-mode with Unicode property support, respectively.
Test 8 checks some internal offsets and code size features, but it is run only
when Unicode support is enabled. The output is different in 8-bit, 16-bit, and
32-bit modes and for different link sizes, so there are different output files
for each mode and link size.
Tests 9 and 10 are run only in 8-bit mode, and tests 11 and 12 are run only in
16-bit and 32-bit modes. These are tests that generate different output in
8-bit mode. Each pair are for general cases and Unicode support, respectively.
Test 13 checks the handling of non-UTF characters greater than 255 by
pcre2_dfa_match() in 16-bit and 32-bit modes.
Test 14 contains some special UTF and UCP tests that give different output for
different code unit widths.
Test 15 contains a number of tests that must not be run with JIT. They check,
among other non-JIT things, the match-limiting features of the interpretive
matcher.
Test 16 is run only when JIT support is not available. It checks that an
attempt to use JIT has the expected behaviour.
Test 17 is run only when JIT support is available. It checks JIT complete and
partial modes, match-limiting under JIT, and other JIT-specific features.
Tests 18 and 19 are run only in 8-bit mode. They check the POSIX interface to
the 8-bit library, without and with Unicode support, respectively.
Test 20 checks the serialization functions by writing a set of compiled
patterns to a file, and then reloading and checking them.
Tests 21 and 22 test \C support when the use of \C is not locked out, without
and with UTF support, respectively. Test 23 tests \C when it is locked out.
Tests 24 and 25 test the experimental pattern conversion functions, without and
with UTF support, respectively.
Test 26 checks Unicode property support using tests that are generated
automatically from the Unicode data tables.
Character tables
----------------
For speed, PCRE2 uses four tables for manipulating and identifying characters
whose code point values are less than 256. By default, a set of tables that is
built into the library is used. The pcre2_maketables() function can be called
by an application to create a new set of tables in the current locale. This are
passed to PCRE2 by calling pcre2_set_character_tables() to put a pointer into a
compile context.
The source file called pcre2_chartables.c contains the default set of tables.
By default, this is created as a copy of pcre2_chartables.c.dist, which
contains tables for ASCII coding. However, if --enable-rebuild-chartables is
specified for ./configure, a new version of pcre2_chartables.c is built by the
program pcre2_dftables (compiled from pcre2_dftables.c), which uses the ANSI C
character handling functions such as isalnum(), isalpha(), isupper(),
islower(), etc. to build the table sources. This means that the default C
locale that is set for your system will control the contents of these default
tables. You can change the default tables by editing pcre2_chartables.c and
then re-building PCRE2. If you do this, you should take care to ensure that the
file does not get automatically re-generated. The best way to do this is to
move pcre2_chartables.c.dist out of the way and replace it with your customized
tables.
When the pcre2_dftables program is run as a result of specifying
--enable-rebuild-chartables, it uses the default C locale that is set on your
system. It does not pay attention to the LC_xxx environment variables. In other
words, it uses the system's default locale rather than whatever the compiling
user happens to have set. If you really do want to build a source set of
character tables in a locale that is specified by the LC_xxx variables, you can
run the pcre2_dftables program by hand with the -L option. For example:
./pcre2_dftables -L pcre2_chartables.c.special
The second argument names the file where the source code for the tables is
written. The first two 256-byte tables provide lower casing and case flipping
functions, respectively. The next table consists of a number of 32-byte bit
maps which identify certain character classes such as digits, "word"
characters, white space, etc. These are used when building 32-byte bit maps
that represent character classes for code points less than 256. The final
256-byte table has bits indicating various character types, as follows:
1 white space character
2 letter
4 lower case letter
8 decimal digit
16 alphanumeric or '_'
You can also specify -b (with or without -L) when running pcre2_dftables. This
causes the tables to be written in binary instead of as source code. A set of
binary tables can be loaded into memory by an application and passed to
pcre2_compile() in the same way as tables created dynamically by calling
pcre2_maketables(). The tables are just a string of bytes, independent of
hardware characteristics such as endianness. This means they can be bundled
with an application that runs in different environments, to ensure consistent
behaviour.

<P>
PCRE2 is the name used for a revised API for the PCRE library, which is a set
of functions, written in C, that implement regular expression pattern matching
using the same syntax and semantics as Perl, with just a few differences. After
nearly two decades, the limitations of the original API were making development
increasingly difficult. The new API is more extensible, and it was simplified
by abolishing the separate "study" optimizing function; in PCRE2, patterns are
automatically optimized where possible. Since forking from PCRE1, the code has
been extensively refactored and new features introduced. The old library is now
obsolete and is no longer maintained.
</P>
<P>
As well as Perl-style regular expression patterns, some features that appeared
in Python and the original PCRE before they appeared in Perl are available
using the Python syntax. There is also some support for one or two .NET and
Oniguruma syntax items, and there are options for requesting some minor changes
that give better ECMAScript (aka JavaScript) compatibility.
</P>
<P>
The source code for PCRE2 can be compiled to support strings of 8-bit, 16-bit,
or 32-bit code units, which means that up to three separate libraries may be
installed, one for each code unit size. The size of code unit is not related to
the bit size of the underlying hardware. In a 64-bit environment that also
supports 32-bit applications, versions of PCRE2 that are compiled in both
64-bit and 32-bit modes may be needed.
</P>
<P>
The original work to extend PCRE to 16-bit and 32-bit code units was done by
Zoltan Herczeg and Christian Persch, respectively. In all three cases, strings
can be interpreted either as one character per code unit, or as UTF-encoded
Unicode, with support for Unicode general category properties. Unicode support
is optional at build time (but is the default). However, processing strings as
UTF code units must be enabled explicitly at run time. The version of Unicode
in use can be discovered by running
<pre>
pcre2test -C
</PRE>
</P>
<P>
The three libraries contain identical sets of functions, with names ending in
_8, _16, or _32, respectively (for example, <b>pcre2_compile_8()</b>). However,
by defining PCRE2_CODE_UNIT_WIDTH to be 8, 16, or 32, a program that uses just
one code unit width can be written using generic names such as
<b>pcre2_compile()</b>, and the documentation is written assuming that this is
the case.
</P>
<P>
In addition to the Perl-compatible matching function, PCRE2 contains an
alternative function that matches the same compiled patterns in a different
way. In certain circumstances, the alternative function has some advantages.
For a discussion of the two matching algorithms, see the
<a href="pcre2matching.html"><b>pcre2matching</b></a>
page.
</P>
<P>
Details of exactly which Perl regular expression features are and are not
supported by PCRE2 are given in separate documents. See the
<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
and
<a href="pcre2compat.html"><b>pcre2compat</b></a>
pages. There is a syntax summary in the
<a href="pcre2syntax.html"><b>pcre2syntax</b></a>
page.
</P>
<P>
Some features of PCRE2 can be included, excluded, or changed when the library
is built. The
<a href="pcre2_config.html"><b>pcre2_config()</b></a>
function makes it possible for a client to discover which features are
available. The features themselves are described in the
<a href="pcre2build.html"><b>pcre2build</b></a>
page. Documentation about building PCRE2 for various operating systems can be
found in the
<a href="README.txt"><b>README</b></a>
and
<a href="NON-AUTOTOOLS-BUILD.txt"><b>NON-AUTOTOOLS_BUILD</b></a>
files in the source distribution.
</P>
<P>
The libraries contains a number of undocumented internal functions and data
tables that are used by more than one of the exported external functions, but
which are not intended for use by external callers. Their names all begin with
"_pcre2", which hopefully will not provoke any name clashes. In some
environments, it is possible to control which external symbols are exported
when a shared library is built, and in these cases the undocumented symbols are
not exported.
</P>
<br><a name="SEC2" href="#TOC1">SECURITY CONSIDERATIONS</a><br>
<P>
If you are using PCRE2 in a non-UTF application that permits users to supply
arbitrary patterns for compilation, you should be aware of a feature that
allows users to turn on UTF support from within a pattern. For example, an
8-bit pattern that begins with "(*UTF)" turns on UTF-8 mode, which interprets
patterns and subjects as strings of UTF-8 code units instead of individual
8-bit characters. This causes both the pattern and any data against which it is
matched to be checked for UTF-8 validity. If the data string is very long, such
a check might use sufficiently many resources as to cause your application to
lose performance.
</P>
<P>
One way of guarding against this possibility is to use the
<b>pcre2_pattern_info()</b> function to check the compiled pattern's options for
PCRE2_UTF. Alternatively, you can set the PCRE2_NEVER_UTF option when calling
<b>pcre2_compile()</b>. This causes a compile time error if the pattern contains
a UTF-setting sequence.
</P>
<P>
The use of Unicode properties for character types such as \d can also be
enabled from within the pattern, by specifying "(*UCP)". This feature can be
disallowed by setting the PCRE2_NEVER_UCP option.
</P>
<P>
If your application is one that supports UTF, be aware that validity checking
can take time. If the same data string is to be matched many times, you can use
the PCRE2_NO_UTF_CHECK option for the second and subsequent matches to avoid
running redundant checks.
</P>
<P>
The use of the \C escape sequence in a UTF-8 or UTF-16 pattern can lead to
problems, because it may leave the current matching point in the middle of a
multi-code-unit character. The PCRE2_NEVER_BACKSLASH_C option can be used by an
application to lock out the use of \C, causing a compile-time error if it is
encountered. It is also possible to build PCRE2 with the use of \C permanently
disabled.
</P>
<P>
Another way that performance can be hit is by running a pattern that has a very
large search tree against a string that will never match. Nested unlimited
repeats in a pattern are a common example. PCRE2 provides some protection
against this: see the <b>pcre2_set_match_limit()</b> function in the
<a href="pcre2api.html"><b>pcre2api</b></a>
page. There is a similar function called <b>pcre2_set_depth_limit()</b> that can
be used to restrict the amount of memory that is used.
</P>
<br><a name="SEC3" href="#TOC1">USER DOCUMENTATION</a><br>
<P>
The user documentation for PCRE2 comprises a number of different sections. In
the "man" format, each of these is a separate "man page". In the HTML format,
each is a separate page, linked from the index page. In the plain text format,
the descriptions of the <b>pcre2grep</b> and <b>pcre2test</b> programs are in
files called <b>pcre2grep.txt</b> and <b>pcre2test.txt</b>, respectively. The
remaining sections, except for the <b>pcre2demo</b> section (which is a program
listing), and the short pages for individual functions, are concatenated in
<b>pcre2.txt</b>, for ease of searching. The sections are as follows:
<pre>
pcre2 this document
pcre2-config show PCRE2 installation configuration information
pcre2api details of PCRE2's native C API
pcre2build building PCRE2
pcre2callout details of the pattern callout feature

<b> void *<i>callout_data</i>);</b>
</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function scans a compiled regular expression and calls the <i>callback()</i>
function for each callout within the pattern. The yield of the function is zero
for success and non-zero otherwise. The arguments are:
<pre>
<i>code</i> Points to the compiled pattern
<i>callback</i> The callback function
<i>callout_data</i> User data that is passed to the callback
</pre>
The <i>callback()</i> function is passed a pointer to a data block containing
the following fields (not necessarily in this order):
<pre>
uint32_t <i>version</i> Block version number
uint32_t <i>callout_number</i> Number for numbered callouts
PCRE2_SIZE <i>pattern_position</i> Offset to next item in pattern
PCRE2_SIZE <i>next_item_length</i> Length of next item in pattern
PCRE2_SIZE <i>callout_string_offset</i> Offset to string within pattern
PCRE2_SIZE <i>callout_string_length</i> Length of callout string
PCRE2_SPTR <i>callout_string</i> Points to callout string or is NULL
</pre>
The second argument passed to the <b>callback()</b> function is the callout data
that was passed to <b>pcre2_callout_enumerate()</b>. The <b>callback()</b>
function must return zero for success. Any other value causes the pattern scan
to stop, with the value being passed back as the result of
<b>pcre2_callout_enumerate()</b>.

<b>#include &#60;pcre2.h&#62;</b>
</P>
<P>
<b>void pcre2_code_free(pcre2_code *<i>code</i>);</b>
</P>
<br><b>
DESCRIPTION
</b><br>
<P>
If <i>code</i> is NULL, this function does nothing. Otherwise, <i>code</i> must
point to a compiled pattern. This function frees its memory, including any
memory used by the JIT compiler. If the compiled pattern was created by a call
to <b>pcre2_code_copy_with_tables()</b>, the memory for the character tables is
also freed.

SYNOPSIS
</b><br>
<P>
<b>#include &#60;pcre2.h&#62;</b>
</P>
<P>
<b>pcre2_code *pcre2_compile(PCRE2_SPTR <i>pattern</i>, PCRE2_SIZE <i>length</i>,</b>
<b> uint32_t <i>options</i>, int *<i>errorcode</i>, PCRE2_SIZE *<i>erroroffset,</i></b>
<b> pcre2_compile_context *<i>ccontext</i>);</b>
</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function compiles a regular expression pattern into an internal form. Its
arguments are:
<pre>
<i>pattern</i> A string containing expression to be compiled
<i>length</i> The length of the string or PCRE2_ZERO_TERMINATED
<i>options</i> Primary option bits
<i>errorcode</i> Where to put an error code
<i>erroffset</i> Where to put an error offset
<i>ccontext</i> Pointer to a compile context or NULL
</pre>
The length of the pattern and any error offset that is returned are in code
units, not characters. A NULL pattern with zero length is treated as an empty
string. A compile context is needed only if you want to provide custom memory
allocation functions, or to provide an external function for system stack size
checking (see <b>pcre2_set_compile_recursion_guard()</b>), or to change one or
more of these parameters:
<pre>
What \R matches (Unicode newlines, or CR, LF, CRLF only);
PCRE2's character tables;
The newline character sequence;
The compile time nested parentheses limit;
The maximum pattern length (in code units) that is allowed;
The additional options bits.
</pre>
The primary option bits are:
<pre>
PCRE2_ANCHORED Force pattern anchoring
PCRE2_ALLOW_EMPTY_CLASS Allow empty classes
PCRE2_ALT_BSUX Alternative handling of \u, \U, and \x
PCRE2_ALT_CIRCUMFLEX Alternative handling of ^ in multiline mode
PCRE2_ALT_EXTENDED_CLASS Alternative extended character class syntax
PCRE2_ALT_VERBNAMES Process backslashes in verb names
PCRE2_AUTO_CALLOUT Compile automatic callouts
PCRE2_CASELESS Do caseless matching
PCRE2_DOLLAR_ENDONLY $ not to match newline at end
PCRE2_DOTALL . matches anything including NL
PCRE2_DUPNAMES Allow duplicate names for subpatterns
PCRE2_ENDANCHORED Pattern can match only at end of subject
PCRE2_EXTENDED Ignore white space and # comments
PCRE2_FIRSTLINE Force matching to be before newline
PCRE2_LITERAL Pattern characters are all literal
PCRE2_MATCH_INVALID_UTF Enable support for matching invalid UTF
PCRE2_MATCH_UNSET_BACKREF Match unset backreferences
PCRE2_MULTILINE ^ and $ match newlines within data
PCRE2_NEVER_BACKSLASH_C Lock out the use of \C in patterns
PCRE2_NEVER_UCP Lock out PCRE2_UCP, e.g. via (*UCP)
PCRE2_NEVER_UTF Lock out PCRE2_UTF, e.g. via (*UTF)
PCRE2_NO_AUTO_CAPTURE Disable numbered capturing paren-
theses (named ones available)
PCRE2_NO_AUTO_POSSESS Disable auto-possessification
PCRE2_NO_DOTSTAR_ANCHOR Disable automatic anchoring for .*
PCRE2_NO_START_OPTIMIZE Disable match-time start optimizations
PCRE2_NO_UTF_CHECK Do not check the pattern for UTF validity
(only relevant if PCRE2_UTF is set)
PCRE2_UCP Use Unicode properties for \d, \w, etc.
PCRE2_UNGREEDY Invert greediness of quantifiers
PCRE2_USE_OFFSET_LIMIT Enable offset limit for unanchored matching
PCRE2_UTF Treat pattern and subjects as UTF strings
</pre>
PCRE2 must be built with Unicode support (the default) in order to use
PCRE2_UTF, PCRE2_UCP and related options.
</P>
<P>
Additional options may be set in the compile context via the
<a href="pcre2_set_compile_extra_options.html"><b>pcre2_set_compile_extra_options</b></a>
function.
</P>
<P>
If either of <i>errorcode</i> or <i>erroroffset</i> is NULL, the function returns
NULL immediately. Otherwise, the yield of this function is a pointer to a
private data structure that contains the compiled pattern, or NULL if an error
was detected. In the error case, a text error message can be obtained by
passing the value returned via the <i>errorcode</i> argument to the
<b>pcre2_get_error_message()</b> function. The offset (in code units) where the
error was encountered is returned via the <i>erroroffset</i> argument.
</P>
<P>
If there is no error, the value passed via <i>errorcode</i> returns the message
"no error" if passed to <b>pcre2_get_error_message()</b>, and the value passed
via <i>erroroffset</i> is zero.
</P>

<b>int pcre2_config(uint32_t <i>what</i>, void *<i>where</i>);</b>
</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function makes it possible for a client program to find out which optional
features are available in the version of the PCRE2 library it is using. The
arguments are as follows:
<pre>
<i>what</i> A code specifying what information is required
<i>where</i> Points to where to put the information
</pre>
If <i>where</i> is NULL, the function returns the amount of memory needed for
the requested information. When the information is a string, the value is in
code units; for other types of data it is in bytes.
</P>
<P>
If <b>where</b> is not NULL, for PCRE2_CONFIG_JITTARGET,
PCRE2_CONFIG_UNICODE_VERSION, and PCRE2_CONFIG_VERSION it must point to a
buffer that is large enough to hold the string. For all other codes it must
point to a uint32_t integer variable. The available codes are:
<pre>
PCRE2_CONFIG_BSR Indicates what \R matches by default:
PCRE2_BSR_UNICODE
PCRE2_BSR_ANYCRLF
PCRE2_CONFIG_COMPILED_WIDTHS Which of 8/16/32 support was compiled
PCRE2_CONFIG_DEPTHLIMIT Default backtracking depth limit
PCRE2_CONFIG_HEAPLIMIT Default heap memory limit
PCRE2_CONFIG_JIT Availability of just-in-time compiler support (1=yes 0=no)
PCRE2_CONFIG_JITTARGET Information (a string) about the target architecture for the JIT compiler
PCRE2_CONFIG_LINKSIZE Configured internal link size (2, 3, 4)
PCRE2_CONFIG_MATCHLIMIT Default internal resource limit
PCRE2_CONFIG_NEVER_BACKSLASH_C Whether or not \C is disabled
PCRE2_CONFIG_NEWLINE Code for the default newline sequence:
PCRE2_NEWLINE_CR
PCRE2_NEWLINE_LF
PCRE2_NEWLINE_CRLF
PCRE2_NEWLINE_ANY
PCRE2_NEWLINE_ANYCRLF
PCRE2_NEWLINE_NUL
PCRE2_CONFIG_PARENSLIMIT Default parentheses nesting limit
PCRE2_CONFIG_RECURSIONLIMIT Obsolete: use PCRE2_CONFIG_DEPTHLIMIT
PCRE2_CONFIG_STACKRECURSE Obsolete: always returns 0
PCRE2_CONFIG_UNICODE Availability of Unicode support (1=yes 0=no)
PCRE2_CONFIG_UNICODE_VERSION The Unicode version (a string)
PCRE2_CONFIG_VERSION The PCRE2 version (a string)
</pre>
The function yields a non-negative value on success or the negative value
PCRE2_ERROR_BADOPTION otherwise. This is also the result for the
PCRE2_CONFIG_JITTARGET code if JIT support is not available. When a string is
requested, the function returns the number of code units used, including the
terminating zero.

</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function matches a compiled regular expression against a given subject
string, using an alternative matching algorithm that scans the subject string
just once (except when processing lookaround assertions). This function is
<i>not</i> Perl-compatible (the Perl-compatible matching function is
<b>pcre2_match()</b>). The arguments for this function are:
<pre>
<i>code</i> Points to the compiled pattern
<i>subject</i> Points to the subject string
<i>length</i> Length of the subject string
<i>startoffset</i> Offset in the subject at which to start matching
<i>options</i> Option bits
<i>match_data</i> Points to a match data block, for results
<i>mcontext</i> Points to a match context, or is NULL
<i>workspace</i> Points to a vector of ints used as working space
<i>wscount</i> Number of elements in the vector
</pre>
The size of output vector needed to contain all the results depends on the
number of simultaneous matches, not on the number of parentheses in the
pattern. Using <b>pcre2_match_data_create_from_pattern()</b> to create the match
data block is therefore not advisable when using this function.
</P>
<P>
A match context is needed only if you want to set up a callout function or
specify the heap limit or the match or the recursion depth limits. The
<i>length</i> and <i>startoffset</i> values are code units, not characters. The
options are:
<pre>
PCRE2_ANCHORED Match only at the first position
PCRE2_COPY_MATCHED_SUBJECT
On success, make a private subject copy
PCRE2_ENDANCHORED Pattern can match only at end of subject
PCRE2_NOTBOL Subject is not the beginning of a line
PCRE2_NOTEOL Subject is not the end of a line
PCRE2_NOTEMPTY An empty string is not a valid match
PCRE2_NOTEMPTY_ATSTART An empty string at the start of the subject is not a valid match
PCRE2_NO_UTF_CHECK Do not check the subject for UTF validity (only relevant if PCRE2_UTF
was set at compile time)
PCRE2_PARTIAL_HARD Return PCRE2_ERROR_PARTIAL for a partial match even if there is a full match
PCRE2_PARTIAL_SOFT Return PCRE2_ERROR_PARTIAL for a partial match if no full matches are found
PCRE2_DFA_RESTART Restart after a partial match
PCRE2_DFA_SHORTEST Return only the shortest match
</pre>
There are restrictions on what may appear in a pattern when using this matching
function. Details are given in the
<a href="pcre2matching.html"><b>pcre2matching</b></a>
documentation. For details of partial matching, see the

<P>
This function creates and initializes a general context. The arguments define
custom memory management functions and a data value that is passed to them when
they are called. The <b>private_malloc()</b> function is used to get memory for
the context. If either of the first two arguments is NULL, the system memory

DESCRIPTION
</b><br>
<P>
This function provides a textual error message for each PCRE2 error code.
Compilation errors are positive numbers; UTF formatting errors and matching
errors are negative numbers. The arguments are:
<pre>
<i>errorcode</i> an error code (positive or negative)
<i>buffer</i> where to put the message
<i>bufflen</i> the length of the buffer (code units)
</pre>
The function returns the length of the message in code units, excluding the
trailing zero, or the negative error code PCRE2_ERROR_NOMEMORY if the buffer is
too small. In this case, the returned message is truncated (but still with a
trailing zero). If <i>errorcode</i> does not contain a recognized error code
number, the negative value PCRE2_ERROR_BADDATA is returned.

<b>int pcre2_jit_compile(pcre2_code *<i>code</i>, uint32_t <i>options</i>);</b>
</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function requests JIT compilation, which, if the just-in-time compiler is
available, further processes a compiled pattern into machine code that executes
much faster than the <b>pcre2_match()</b> interpretive matching function. Full
details are given in the
<a href="pcre2jit.html"><b>pcre2jit</b></a>
documentation.
</P>
<P>
The availability of JIT support can be tested by calling
<b>pcre2_compile_jit()</b> with a single option PCRE2_JIT_TEST_ALLOC (the
code argument is ignored, so a NULL value is accepted). Such a call
returns zero if JIT is available and has a working allocator. Otherwise
it returns PCRE2_ERROR_NOMEMORY if JIT is available but cannot allocate
executable memory, or PCRE2_ERROR_JIT_UNSUPPORTED if JIT support is not
compiled.
</P>
<P>
Otherwise, the first argument must be a pointer that was returned by a
successful call to <b>pcre2_compile()</b>, and the second must contain one or
more of the following bits:
<pre>
PCRE2_JIT_COMPLETE compile code for full matching
PCRE2_JIT_PARTIAL_SOFT compile code for soft partial matching
PCRE2_JIT_PARTIAL_HARD compile code for hard partial matching
</pre>
There is also an obsolete option called PCRE2_JIT_INVALID_UTF, which has been
superseded by the <b>pcre2_compile()</b> option PCRE2_MATCH_INVALID_UTF. The old
option is deprecated and may be removed in the future.
</P>
<P>
The yield of the function when called with any of the three options above is 0
for success, or a negative error code otherwise. In particular,
PCRE2_ERROR_JIT_BADOPTION is returned if JIT is not supported or if an unknown
bit is set in <i>options</i>. The function can also return PCRE2_ERROR_NOMEMORY
if JIT is unable to allocate executable memory for the compiler, even if it was
because of a system security restriction. In a few cases, the function may
return with PCRE2_ERROR_JIT_UNSUPPORTED for unsupported features.

<br><b>
DESCRIPTION
</b><br>
<P>
This function matches a compiled regular expression that has been successfully
processed by the JIT compiler against a given subject string, using a matching
algorithm that is similar to Perl's. It is a "fast path" interface to JIT, and
it bypasses some of the sanity checks that <b>pcre2_match()</b> applies.
</P>
<P>
In UTF mode, the subject string is not checked for UTF validity. Unless
PCRE2_MATCH_INVALID_UTF was set when the pattern was compiled, passing an
invalid UTF string results in undefined behaviour. Your program may crash or
loop or give wrong results. In the absence of PCRE2_MATCH_INVALID_UTF you
should only call <b>pcre2_jit_match()</b> in UTF mode if you are sure the
subject is valid.
</P>
<P>
The arguments for <b>pcre2_jit_match()</b> are exactly the same as for
<a href="pcre2_match.html"><b>pcre2_match()</b>,</a>
except that the subject string must be specified with a length;
PCRE2_ZERO_TERMINATED is not supported.
</P>
<P>
The supported options are PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY,
PCRE2_NOTEMPTY_ATSTART, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. Unsupported
options are ignored.
</P>
<P>
The return values are the same as for <b>pcre2_match()</b> plus
PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or complete) is requested
that was not compiled. For details of partial matching, see the

DESCRIPTION
</b><br>
<P>
This function provides control over the memory used by JIT as a run-time stack
when <b>pcre2_match()</b> or <b>pcre2_jit_match()</b> is called with a pattern
that has been successfully processed by the JIT compiler. The information that
determines which stack is used is put into a match context that is subsequently

If <i>callback</i> is NULL and <i>callback_data</i> is NULL, an internal 32KiB
block on the machine stack is used.
</P>
<P>
If <i>callback</i> is NULL and <i>callback_data</i> is not NULL,
<i>callback_data</i> must be a valid JIT stack, the result of calling
<b>pcre2_jit_stack_create()</b>.
</P>
<P>
If <i>callback</i> not NULL, it is called with <i>callback_data</i> as an
argument at the start of matching, in order to set up a JIT stack. If the
result is NULL, the internal 32KiB stack is used; otherwise the return value
must be a valid JIT stack, the result of calling
<b>pcre2_jit_stack_create()</b>.
</P>
<P>
You may safely use the same JIT stack for multiple patterns, as long as they
are all matched in the same thread. In a multithread application, each thread
must use its own JIT stack. For more details, see the

</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function is used to create a stack for use by the code compiled by the JIT
compiler. The first two arguments are a starting size for the stack, and a
maximum size to which it is allowed to grow. The final argument is a general
context, for memory allocation functions, or NULL for standard memory
allocation. The result can be passed to the JIT run-time code by calling
<b>pcre2_jit_stack_assign()</b> to associate the stack with a compiled pattern,
which can then be processed by <b>pcre2_match()</b> or <b>pcre2_jit_match()</b>.
A maximum stack size of 512KiB to 1MiB should be more than enough for any
pattern. If the stack couldn't be allocated or the values passed were not
reasonable, NULL will be returned. For more details, see the
<a href="pcre2jit.html"><b>pcre2jit</b></a>
page.

DESCRIPTION
</b><br>
<P>
This function builds a set of character tables for character code points that
are less than 256. These can be passed to <b>pcre2_compile()</b> in a compile
context in order to override the internal, built-in tables (which were either
defaulted or made by <b>pcre2_maketables()</b> when PCRE2 was compiled). See the

page. You might want to do this if you are using a non-standard locale.
</P>
<P>
If the argument is NULL, <b>malloc()</b> is used to get memory for the tables.
Otherwise it must point to a general context, which can supply pointers to a
custom memory manager. The function yields a pointer to the tables.

</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function matches a compiled regular expression against a given subject
string, using a matching algorithm that is similar to Perl's. It returns
offsets to what it has matched and to captured substrings via the
<b>match_data</b> block, which can be processed by functions with names that
start with <b>pcre2_get_ovector_...()</b> or <b>pcre2_substring_...()</b>. The
return from <b>pcre2_match()</b> is one more than the highest numbered capturing
pair that has been set (for example, 1 if there are no captures), zero if the
vector of offsets is too small, or a negative error code for no match and other
errors. The function arguments are:
<pre>
<i>code</i> Points to the compiled pattern
<i>subject</i> Points to the subject string
<i>length</i> Length of the subject string
<i>startoffset</i> Offset in the subject at which to start matching
<i>options</i> Option bits
<i>match_data</i> Points to a match data block, for results
<i>mcontext</i> Points to a match context, or is NULL
</pre>
A match context is needed only if you want to:
<pre>
Set up a callout function
Set a matching offset limit
Change the heap memory limit
Change the backtracking match limit
Change the backtracking depth limit
Set custom memory management specifically for the match
</pre>
The <i>length</i> and <i>startoffset</i> values are code units, not characters.
The length may be given as PCRE2_ZERO_TERMINATED for a subject that is
terminated by a binary zero code unit. The options are:
<pre>
PCRE2_ANCHORED Match only at the first position
PCRE2_COPY_MATCHED_SUBJECT
On success, make a private subject copy
PCRE2_DISABLE_RECURSELOOP_CHECK
Only useful in rare cases; use with care
PCRE2_ENDANCHORED Pattern can match only at end of subject
PCRE2_NOTBOL Subject string is not the beginning of a line
PCRE2_NOTEOL Subject string is not the end of a line
PCRE2_NOTEMPTY An empty string is not a valid match
PCRE2_NOTEMPTY_ATSTART An empty string at the start of the subject is not a valid match
PCRE2_NO_JIT Do not use JIT matching
PCRE2_NO_UTF_CHECK Do not check the subject for UTF validity (only relevant if PCRE2_UTF
was set at compile time)
PCRE2_PARTIAL_HARD Return PCRE2_ERROR_PARTIAL for a partial match even if there is a full match
PCRE2_PARTIAL_SOFT Return PCRE2_ERROR_PARTIAL for a partial match if no full matches are found
</pre>

DESCRIPTION
</b><br>
<P>
This function creates a new match data block for holding the result of a match.
The first argument points to a compiled pattern. The number of capturing
parentheses within the pattern is used to compute the number of pairs of
offsets that are required in the match data block. These form the "output
vector" (ovector) within the match data block, and are used to identify the
matched string and any captured substrings when matching with
<b>pcre2_match()</b>. If you are using <b>pcre2_dfa_match()</b>, which uses the
output vector in a different way, you should use <b>pcre2_match_data_create()</b>
instead of this function.
</P>
<P>
The second argument points to a general context, for custom memory management,
or is NULL to use the same memory allocator as was used for the compiled
pattern. The result of the function is NULL if the memory for the block could
not be obtained.

</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function is part of an experimental set of pattern conversion functions.
It converts a foreign pattern (for example, a glob) into a PCRE2 regular
expression pattern. Its arguments are:
<pre>
<i>pattern</i> The foreign pattern
<i>length</i> The length of the input pattern or PCRE2_ZERO_TERMINATED
<i>options</i> Option bits
<i>buffer</i> Pointer to pointer to output buffer, or NULL
<i>blength</i> Pointer to output length field
<i>cvcontext</i> Pointer to a convert context or NULL
</pre>
The length of the converted pattern (excluding the terminating zero) is

the output length. If <i>buffer</i> points to a NULL pointer, heap memory is
obtained for the converted pattern, using the allocator in the context if
present (or else <b>malloc()</b>), and the field pointed to by <i>buffer</i> is
updated. If <i>buffer</i> points to a non-NULL field, that must point to a
buffer whose size is in the variable pointed to by <i>blength</i>. This value is
updated.

DESCRIPTION
</b><br>
<P>
This function decodes a serialized set of compiled patterns back into a list of
individual patterns. This is possible only on a host that is running the same
version of PCRE2, with the same code unit width, and the host must also have
the same endianness, pointer width and PCRE2_SIZE type. The arguments for
<b>pcre2_serialize_decode()</b> are:
<pre>
<i>codes</i> pointer to a vector in which to build the list
<i>number_of_codes</i> number of slots in the vector
<i>bytes</i> the serialized byte stream
<i>gcontext</i> pointer to a general context or NULL
</pre>
The <i>bytes</i> argument must point to a block of data that was originally
created by <b>pcre2_serialize_encode()</b>, though it may have been saved on
disc or elsewhere in the meantime. If there are more codes in the serialized
data than slots in the list, only those compiled patterns that will fit are
decoded. The yield of the function is the number of decoded patterns, or one of
the following negative error codes:
<pre>
PCRE2_ERROR_BADDATA <i>number_of_codes</i> is zero or less
PCRE2_ERROR_BADMAGIC mismatch of id bytes in <i>bytes</i>
PCRE2_ERROR_BADMODE mismatch of variable unit size or PCRE version
PCRE2_ERROR_NOMEMORY memory allocation failed
PCRE2_ERROR_NULL <i>codes</i> or <i>bytes</i> is NULL
</pre>
PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled
on a system with different endianness.

</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function encodes a list of compiled patterns into a byte stream that can
be saved on disc or elsewhere. Note that this is not an abstract format like
Java or .NET. Conversion of the byte stream back into usable compiled patterns
can only happen on a host that is running the same version of PCRE2, with the
same code unit width, and the host must also have the same endianness, pointer
width and PCRE2_SIZE type. The arguments for <b>pcre2_serialize_encode()</b>
are:
<pre>
<i>codes</i> pointer to a vector containing the list
<i>number_of_codes</i> number of slots in the vector
<i>serialized_bytes</i> set to point to the serialized byte stream
<i>serialized_size</i> set to the number of bytes in the byte stream
<i>gcontext</i> pointer to a general context or NULL
</pre>
The context argument is used to obtain memory for the byte stream. When the
serialized data is no longer needed, it must be freed by calling
<b>pcre2_serialize_free()</b>. The yield of the function is the number of
serialized patterns, or one of the following negative error codes:
<pre>
PCRE2_ERROR_BADDATA <i>number_of_codes</i> is zero or less
PCRE2_ERROR_BADMAGIC mismatch of id bytes in one of the patterns
PCRE2_ERROR_MEMORY memory allocation failed
PCRE2_ERROR_MIXEDTABLES the patterns do not all use the same tables
PCRE2_ERROR_NULL an argument other than <i>gcontext</i> is NULL
</pre>
PCRE2_ERROR_BADMAGIC means either that a pattern's code has been corrupted, or
that a slot in the vector does not point to a compiled pattern.

non-zero to force an error. This feature is provided so that applications can
check the available system stack space, in order to avoid running out. The
result of <b>pcre2_set_compile_recursion_guard()</b> is always zero.

<P>
This function is part of an experimental set of pattern conversion functions.
It sets the escape character that is used when converting globs. The second
argument must either be zero (meaning there is no escape character) or a
punctuation character whose code point is less than 256. The default is grave
accent if running under Windows, otherwise backslash. The result of the
function is zero for success or PCRE2_ERROR_BADDATA if the second argument is
invalid.
