Various related changes, including refactoring part of dataset creation, and reworking how layout versions are calculated.
Needs more testing of filters that create very large chunks, but that will need code to turn it off in cases where we can't allocate >4GiB buffers. I tested this manually by increasing the expansion ration in the expand2 test in dsets, and it passed everything up until it tried to expand the datasets with H5Dset_extent() and my laptop ran out of disk space.
We should add code and testing to handle the case where the "size of size" is set less than 8 bytes. This is not a new issue, since it can be set to 2.
I will file issues for these, but I don't think they are necessary for the release.
Change default file format to 1.8 across various tests and examples, updating file creation and access logic accordingly.
Behavior:
Default file format version changed to 1.8 in H5Pfapl.c.
Updated file creation and access to use 1.8 format in h5ex_g_compact.c and test_file_image.c.
Set earliest file format in multiple test files including cache_tagging.c, dtypes.c, and links.c.
Tests:
Modified expected output in tools/test/misc/expected/*.ls files to reflect new file format locations.
Adjusted test logic in test_file_image.c and cache_tagging.c to accommodate format changes.
Misc:
Added comments and TODOs for future format testing in test_file_image.c.
Minor variable renaming for clarity in test_file_image.c.
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.
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.
* Fix for issue #4849 that settings in fapl libver bounds causes unexpected H5Fopen failures.
File with non-SWMR-write access can now be opened without regard for superblock version.
Due to the fix, H5Fstart_swmr_write() also needs to be modified as well as the tests for libver bounds.
The "RFC: Setting Bounds for Object Creation in HDF5 1.10.0" is also updated to reflect the changes.
* Fix c++ libver bound test failure.
Cleanup and prepare for thread-safety changes.
Big ideas:
* Wrap H5VL_class_t with H5VL_connector_t, so use of the class can be refcounted within the H5VL package, instead of relying on storing an ID within the H5VL_t struct and incrementing & decrementing the ID's refcount.
* Register H5VL_connector_t* for VOL connector IDs, instead of the H5VL_class_t*
* Stop other packages from rummaging around inside H5VL_connector_t and H5VL_object_t data structures, so that the H5VL package can change implementation details without coupled changes throughout the library
Small things:
* Simplified the coding for creating links
* Moved some routines into more logical locations
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
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
When clearing out datatype conversion paths involving variable-length or reference datatypes
on file close, also check for these datatypes inside compound or array datatypes
* Fixed asserts due to H5Pset_est_link_info() values
If large values for est_num_entries and/or est_name_len were passed
to H5Pset_est_link_info(), the library would attempt to create an
object header NIL message to reserve enough space to hold the links in
compact form (i.e., concatenated), which could exceed allowable object
header message size limits and trip asserts in the library.
This bug only occurred when using the HDF5 1.8 file format or later and
required the product of the two values to be ~64k more than the size
of any links written to the group, which would cause the library to
write out a too-large NIL spacer message to reserve the space for the
unwritten links.
The library now inspects the phase change values to see if the dataset
is likely to be compact and checks the size to ensure any NIL spacer
messages won't be larger than the library allows.
Fixes GitHub #1632
* Fix copy-paste comments
Remove cached datatype conversion path table entries on file close
When performing datatype conversions during I/O, the library
checks to see whether it can re-use a cached datatype conversion
pathway by performing comparisons between the source and destination
datatypes of the current operation and the source and destination
datatypes associated with each cached datatype conversion pathway.
For variable-length and reference datatypes, a comparison is made
between the VOL object for the file associated with these datatypes,
which may change as a file is closed and reopened. In workflows
involving a loop that opens a file, performs I/O on an object with a
variable-length or reference datatype and then closes the file, this
can lead to constant memory usage growth as the library compares the
file VOL objects between the datatypes as different and adds a new
cached conversion pathway entry on each iteration during I/O. This is
now fixed by clearing out any cached conversion pathway entries for
variable-length or reference datatypes associated with a particular
file when that file is closed.
* 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

szip (or libaec) is currently not tested in CI. This adds szip to the
the Autotools GitHub CI actions on Linux when building with the
Autotools.
This PR also cleans up a few warnings that remained in the szip-
related code so the -Werror check will pass.
* Fix for HDFFV-11052: h5debug fails on a corrupted file (h5_nrefs_POC) producing a core dump.
When h5debug closes the corrupted file, the library calls H5F__dest() which performs all the
closing operations for the file "f" (H5F_t *) but just keeping note of errors in "ret_value"
all the way till the end of the routine. The user-provided corrupted file has an illegal
file size causing failure when reading the image during the closing process.
At the end of this routine it sets f->shared to NULL and then frees "f".
This is done whether there is error or not in "ret_value".
Due to the failure in reading the file earlier, the routine then returns error.
The error return from H5F__dest() causes the file object "f" not being removed from the
ID node table. When the library finally exits, it will try to close the
file objects in the table. This causes assert failure when H5F_ID_EXISTS(f) or H5F_NREFS(f).
Fix:
a) H5F_dest(): free the f only when there is no error in "ret_value" at the end of the routine.
b) H5VL__native_file_close(): if f->shared is NULL, free "f"; otherwise, perform closing on "f" as before.
c) h5debug.c main(): track error return from H5Fclose().

* Updated source file copyright headers to remove "Copyright by the Board of Trustees
of the University of Illinois", which is kept in the top-level COPYING file.
* Add Developer build mode to CMake
* Set a few CMake variables for Developer build modes
* Refactor enabling of debug and developer-level compile definitions
* Convert cache debugging macros to normal ifdef style
Normal ifdef-style instead of if-style allows build system to define macros
without warning about redefining macros with different values (0 vs. 1)
* Add HDF5 Developer compile definitions to testing files
* Temporarily disable -fanalyzer flag for GCC 12+ Developer builds
* Added support for vector I/O calls to the VFD layer, and
associated test code. Note that this includes the optimization
to allow shortened sizes and types arrays to allow more space
efficient representations of vectors in which all entries are
of the same size and/or type. See the Selection I/o RFC for
further details.
Tested serial and parallel, debug and production on Charis.
serial and parallel debug only on Jelly.
* ran code formatter
quick serial build and test on jelly
* Add H5FD_read_selection() and H5FD_write_selection(). Currently only
translate to scalar calls. Fix const buf in H5FD_write_vector().
* Format source
* Fix comments
* Add selection I/O to chunk code, used when: not using chunk cache, no
datatype conversion, no I/O filters, no page buffer, not using collective
I/O. Requires global variable H5_use_selection_io_g be set to TRUE.
Implemented selection to vector I/O transaltion at the file driver
layer.
* Fix formatting unrelated to previous change to stop github from
complaining.
* Add full API support for selection I/O. Add tests for this.
* Implement selection I/O for contiguous datasets. Fix bug in selection
I/O translation. Add const qualifiers to some internal selection I/O
routines to maintain const-correctness while avoiding memcpys.
* Added vector read / write support to the MPIO VFD, with associated
test code (see testpar/t_vfd.c).
Note that this implementation does NOT support vector entries of
size greater than 2 GB. This must be repaired before release,
but it should be good enough for correctness testing.
As MPIO requires vector I/O requests to be sorted in increasing
address order, also added a vector sort utility in H5FDint.c This
function is tested in passing by the MPIO vector I/O extension.
In passing, repaired a bug in size / type vector extension management
in H5FD_read/write_vector()
Tested parallel debug and production on charis and Jelly.
* Ran source code formatter
* Add support for independent parallel I/O with selection I/O. Add
HDF5_USE_SELECTION_IO env var to control selection I/O (default off).

* Merged my subfiling code fixes into the new selection_io_branch
* Forgot to add the FindMERCURY.cmake file. This will probably disappear soon
* attempting to make a more reliable subfile file open which doesn't return errors. For some unknown reason, the regular posix open will occasionally fail to create a subfile. Some better error handling for file close has been added.
* added NULL option for H5FD_subfiling_config_t in H5Pset_fapl_subfiling (#1034)
* NULL option automatically stacks IOC VFD for subfiling and returns a valid fapl.
* added doxygen subfiling APIs
* Various fixes which allow the IOR benchmark to run correctly
* Lots of updates including the packaging up of the mercury_util source files to enable easier builds for our Benchmarking
* Interim checkin of selection_io_with_subfiling_vfd branch
Moddified testpar/t_vfd.c to test the subfiling vfd with default configuration.
Must update this code to run with a variety of configurations -- most particularly
multiple IO concentrators, and stripe depth small enough to test the other IO
concentrators.
testpar/t_vfd.c exposed a large number of race condidtions -- symtoms included:
1) Crashes (usually seg faults)
2) Heap corruption
3) Stack corruption
4) Double frees of heap space
5) Hangs
6) Out of order execution of I/O requests / violations of POSIX semantics
7) Swapped write requests
Items 1 - 4 turned out to be primarily caused by file close issues --
specifically, the main I/O concentrator thread and its pool of worker threads
were not being shut down properly on file close. Addressing this issue in
combination with some other minor fixes seems to have addressed these issues.
Items 5 & 6 appear to have been caused by issue of I/O requests to the
thread pool in an order that did not maintain POSIX semantics. A rewrite of
the I/O request dispatch code appears to have solved these issues.
Item 7 seems to have been caused by multiple write requests from a given
rank being read by the wrong worker thread. Code to issue "unique" tags for
each write request via the ACK message appears to have cleaned this up.
Note that the code is still in poor condtition. A partial list of known
defects includes:
a) Race condiditon on file close that allows superblock writes to arrive
at the I/O concentrator after it has been shutdown. This defect is
most evident when testpar/t_subfiling_vfd is run with 8 ranks.
b) No error reporting from I/O concentrators -- must design and implement
this. For now, mostly just asserts, which suggests that it should be
run in debug mode.
c) Much commented out and/or un-used code.
d) Code orgnaization
e) Build system with bits of Mercury is awkward -- think of shifting
to pthreads with our own thread pool code.
f) Need to add native support for vector and selection I/O to the subfiling
VFD.
g) Need to review, and posibly rework configuration code.
h) Need to store subfile configuration data in a superblock extension message,
and add code to use this data on file open.
i) Test code is inadequate -- expect more issues as it is extended.
In particular, there is no unit test code for the I/O request dispatch code.
While I think it is correct at present, we need test code to verify this.
Similarly, we need to test with multiple I/O concentrators and much smaller
stripe depth.
My actual code changes were limited to:
src/H5FDioc.c
src/H5FDioc_threads.c
src/H5FDsubfile_int.c
src/H5FDsubfile_mpi.c
src/H5FDsubfiling.c
src/H5FDsubfiling.h
src/H5FDsubfiling_priv.h
testpar/t_subfiling_vfd.c
testpar/t_vfd.c
I'm not sure what is going on with the deletions in src/mercury/src/util.

This exposed issues with truncate and get EOF in the sub-filing VFD.
I believe I have addressed these issues (get EOF not as fully tested as it should be), howeer,
it exposed race conditions resulting in hangs. As of this writing, I have not been able
to chase these down.
Note that the tests that expose these race conditions are in testpar/t_subfiling_vfd.c, and
are currently skipped. Unskip these tests to reproduce the race conditions.
