Fixes security issue by treating non-NULL buffer with size 0 as length-only query in get_name API functions.
Behavior:
Modify get_name API functions to treat (buffer != NULL, size == 0) as length-only queries, preventing undefined behavior.
Fix applied to H5Aget_name, H5Aget_name_by_idx, H5Fget_name, H5Gget_objname_by_idx, H5Iget_name, H5Lget_name_by_idx, H5Rget_file_name, H5Rget_obj_name, H5Rget_attr_name, and 8 other functions.
Tests:
Update test/links.c, test/tattr.c, test/tfile.c, test/titerate.c, and test/trefer.c to verify new behavior with non-null buffer and size 0.
Documentation:
Update comments in H5A.c, H5F.c, H5Gdeprec.c, H5I.c, H5L.c, H5R.c, and H5Rdeprec.c to reflect new behavior.t]@users.noreply.github.com>
Move the portion of test_reference_external() in charge of test file creation to its own dedicated function. This will eventually be helpful if/when we change the test file creation here to used a shared routine.
Makes testing parameters specified with AddTest non-const again when
passed to test functions. This allows test functions to update their
parameters during execution and is particularly useful for tests
which use those parameters to accumulate statistics, error counts,
etc. without resorting to global variables.
gcc 14 identifies likely places where the sizeof() call is used
for the first parameter to calloc(). This PR fixes the remaining
places in the library where this occurs and reworks a few other
allocations to be more uniform.
Since each API context is local to a thread, use the stack to
store the context instead of allocating & releasing it each time.
This improves performance (slightly), reduces alloc/free calls,
and eliminates the H5FL package from the push & pop operations,
which helps simplify threadsafe operation.
One effect of this change is that the H5VLstart_lib_state /
H5VLfinish_lib_state API routines for pass through connector
authors now require a parameter that can be used to store
the library's context. It was probably a mistake to assume
that these two routines would not do this previously, so this
is essentially a bug fix for them.
Some other minor things:
* Added API context push+pop operations to cache tests
(I'm not actually certain why this was working before) and
a few other places
* Cleaned up a bunch of warnings in test code (calloc args, mainly)
* Made header file inclusions more standard in some source files
This is where most people will expect to find license information. The
COPYING_LBNL_HDF5 file has also been renamed to LICENSE_LBNL_HDF5.
The licenses are unchanged.
Added new testframe.h header to document testing framework functions and
split them away from h5test.h and from test programs that don't
integrate with the testframe.c testing framework
Added new test setup callback to testframe.c testing framework
Added parameters to AddTest() to specify size of test parameters so they
can be copied for later use
Enabled HDF5 error stacks in testframe.c framework by default and added
some error stack suppressions to some testhdf5 tests
Added new maxthreads option to testframe.c framework to allow specifying
the maximum number of threads a multi-threaded test can use
Moved TestExpress functionality out of testframe.c and into more general
h5test.c for wider use by tests through getter and setter
Updated some tests to not mix and match functionality between h5test.c/h
and testframe.c/h
Moved some functionality from testphdf5.h into testpar.h for parallel
tests that aren't part of testphdf5
Added new parallel test library that contains common shared
functionality for parallel tests (similar to h5test library)
- Verified that the listed functions do not include null terminator in the returned length
- Improved some of the tests
- Corrected documentation
Fixes GH-4704
* Casted a positive int to size_t
Added functionality tests for the following APIs:
H5Rget_file_name
H5Rget_obj_name
H5Rget_attr_name
Also removed "+1" when returning a name length in H5R__get_attr_name().
The exter "+1" gave an incorrect value for the length of the referenced
object's attribute name.
Fixed GH-4447
* Fix Fortran test
The C API H5Rget_attr_name incorrectly added 1 to the length of the
referenced object's attribute name, so the Fortran API h5rget_attr_name_f
removed 1 from the returned value to accommodate the incorrectness.
This PR fixes H5Rget_attr_name so this workaround in h5rget_attr_name_f
is no longer needed.
* Add test H5Aget_name against H5Rget_attr_name
- Add Fortran H5R APIs:
h5rcreate_attr_f, h5rcreate_object_f, h5rcreate_region_f,
h5ropen_attr_f, h5ropen_object_f, h5ropen_region_f,
h5rget_file_name_f, h5rget_attr_name_f, h5rget_obj_name_f,
h5rcopy_f, h5requal_f, h5rdestroy_f, h5rget_type_f
- Fixed function H5Requal actually to compare the reference pointers
Fixed an issue with H5Requal always returning true because the
function was only comparing the ref2_ptr to itself.
Changes Autotools testing to use HDF5_TEST_DRIVER environment
variable to avoid running tests that don't work well with several
VFDs
Restores old h5_get_vfd_fapl() testing function to setup a FAPL
with a particular VFD
Adds a macro for the default VFD name
* HDF5 API test updates
Removed test duplication from bringing API tests
back into the library from external VOL tests
repo
Synced changes between API tests and library's
tests
Updated API tests CMake code to directly use and
install testhdf5, testphdf5, etc. instead of
creating duplicate binaries
Added new h5_using_native_vol() test function to
determine whether the VOL connector being used
is (or the VOL connector stack being used resolves
to) the native VOL connector
* Remove duplicate variable
* Strip HD prefix from string/char C API calls
* HD(f)(put|get)(s|c)
* HDstr*
* HDv*printf
* HD(s)(print|scan)f
* HDperror
But NOT:
* HDstrcase*
* HDvasprintf
* HDstrtok_r
* HDstrndup
As those are not C99 and have portability work-around
implementations. They will be handled later.
* Fix th5_system.c screwup
* Fixed extra semi warning by adjusting alternative macro definitions
* Find-replace H5E_END_TRY; -> H5E_END_TRY
* Made H5Epush_goto a do-while loop, fixed indentation
* Made GOTOERROR and ERRMSG do-while loops
* Made Hgoto_error and Hgoto_done do-while loops
* Made vrfy_cint_type and vrfy_ctype do-while loops
* Made TEST_TYPE_CONTIG and others do-while loops

This is triggered by the tests for revised references when the libver bounds setting does not allow version
4 datatype message to be created. The test failure is abort core dumped.
This is due to the datatype initialization fails before the datatype ID is registered.
The datatype cleanup code should provide for the above situation.
The code to fix the problem is the same as what is done in H5D__open_oid().
Reduce gratuitous casts---e.g., (size_t)1.
Use the right format string for a pointer.
In the H5C sanity checks, change a "size increase" variable from ssize_t
(too narrow) to int64_t (wide enough).
Parenthesize every appearance of `storage` in the macro
`H5D_CHUNK_STORAGE_INDEX_CHK(storage)` so that you can pass in an
expression like &sc and it works properly.
Disallow re-assignment of the `dset` parameter to H5D__chunk_init()
because it helped assure me that it's safe to replace the repeating
expression `&dset->shared->layout.storage.u.chunk` with `sc` throughout.
Replace lengthy expressions such as
`&dset->shared->layout.storage.u.chunk` with `sc` throughout several
functions in H5Dchunk.c ISTR that the compiler warned that `sc` was
declared but unused in a couple of functions, and then I found that `sc`
could be used in many places. Maybe the disused `sc` appeared because a
bunch of code was copied and pasted, I don't know. Anyway, it's a lot
tighter code now that I use `sc`.
In H5D__chunk_update_old_edge_chunks() and H5D__chunk_delete()
I actually expand `sc` and another temporary variable, `pline`,
because they're used only in !defined(NDEBUG) code. This squashes
unused-variable warnings in the defined(NDEBUG) configuration.
Don't drop the `volatile` qualification with a cast in
tools/src/h5import/h5import.c.
of the va_list, so it's at least possible for another connector to know what
the operation is and decide whether to implement it or not.
Added a new VOL sub-class called "introspect" where callbacks that report
information about the connector or container can be placed. Added an
'opt_query' callback to this sub-class, for a connector to report back
to the library whether a particular optional callback operation is supported.
Also added a 'get_conn_cls' introspection callback, to retrieve the H5VL_class_t
of a connector (either the "current" connector, H5VL_GET_CONN_LVL_CURR, or
the terminal connector, H5VL_GET_CONN_LVL_TERM).
Moved the "post open" operation from a file 'specific' operation to a file
'optional' operation, now that it's possible to detect (with the 'opt_query'
introspection callback) whether a VOL connector implements an optional
operation, without just returning an error.
Added new internal VOL helper routines: H5VL_object_is_native, to determine
if an object is in (or is a) native file, and H5VL_file_is_same, to determine
if two objects are in (or are) the same terminal VOL connector's container.
(And moved the special handling for FILE_IS_EQUAL operation out of internal VOL
callback routine into H5VL_file_is_same)
Made new dataset 'get' operation for H5Dvlen_get_buf_size, aligning it better
with other 'get' operations in API.
Fixed several issues with pass-through connectors, which are now passing the
'make check-passthrough-vol' tests again.
A bunch of warning and style cleanups as well.
