* Fix typo in error message for `MPI_Type_dup`. (#3867)Luc Grosheintz2023-11-221-1/+1
|
* Fix segfault on user compound dtype conversion callback (#3842)mattjala2023-11-221-7/+10
| | | | | | * Fix segfault on user compound conversion * Check if lib conversion func is in use
* Implement selection vector I/O with collective chunk filling (#3826)vchoi-hdfgroup2023-11-162-170/+122
| | | | | | | | | | | | | | | | | * Changes for ECP-344: Implement selection vector I/O with collective chunk filling. Also fix a bug in H5FD__mpio_write_vector() to account for fixed size optimization when computing max address. * Fixes based on PR review comments: For H5Dchunk.c: fix H5MM_xfree() For H5FDmpio.c: 1) Revert the fix to H5FD__mpio_write_vector() 2) Apply the patch from Neil on the proper length of s_sizes reported by H5FD__mpio_vector_build_types() * Put back the logic of dividing up the work among all the mpi ranks similar to the original H5D__chunk_collective_fill() routine. * Add a test to verify the fix for the illegal reference problem in H5FD__mpio_write_vector().
* Change dest for doxygen (#3856)Allen Byrne2023-11-152-5/+5
| | | * Switch doxygen refs to hdf5/develop
* Make filter unregister callbacks safe for VOL connectors (#3629)mattjala2023-11-131-44/+98
| | | | | | | | | | | | * Make filter callbacks use top-level API functions When using VOL connectors, H5I_iterate may not provide valid object pointers to its callback. This change keeps existing functionality in H5Zunregister() without using potentially unsafe pointers. * Filter callbacks use internal API * Skip MPI work on non-native VOL
* Test and document path handling of H5Lcreate_* API (#3829)mattjala2023-11-111-7/+20
|
* Disable FP exceptions in H5T init code (#3837)Dana Robinson2023-11-072-18/+37
| | | | | | | The H5T floating-point datatype initialization code can raise exceptions when handling signaling NaNs. This change disables FE_INVALID exceptions during initialization. Also removes the -ieee=full change for NAG Fortran as that shouldn't be necessary anymore. Fixes #3831
* Rework MPI Info FAPL preserve PR to use VFD 'ctl' operations (#3782)jhendersonHDF2023-11-039-29/+95
|
* Fix misc. warnings from GCC when compiling with -fsanitize=undefined (#3787)jhendersonHDF2023-11-015-7/+9
|
* Remove H5system.c warning on Windows oneAPI. (#3812)H. Joe Lee2023-11-011-2/+1
|
* Fix a couple usages of MPI_Info_get (#3809)jhendersonHDF2023-10-312-4/+4
|
* Update Doxygen initializers & identifiers in VFDs (#3795)Dana Robinson2023-10-3014-52/+163
| | | | | * Add Doxygen for all H5FD_<VFD> initializers * Add Doxygen for all H5FD_<VFD>_VALUE values * Mark H5FD_<vfd>_init() calls private in Doxygen
* Add Doxygen to H5FDsplitter.h (#3794)Dana Robinson2023-10-301-55/+54
| | | | | | | | | * H5FD_CURR_SPLITTER_VFD_CONFIG_VERSION * H5FD_SPLITTER_PATH_MAX * H5FD_SPLITTER_MAGIC * H5FD_splitter_vfd_config_t * H5Pset_fapl_splitter() * H5Pget_fapl_splitter()
* Avoid attempted use of NULL pointer in parallel compression code (#3786)jhendersonHDF2023-10-281-0/+4
| | | The parallel compression test code tests for the case where all MPI ranks have no selection in a dataset when writing to it. Add an early exit to the code to avoid attempting to use a NULL pointer due to there being no work to do.
* Fixed a file handle leak in the core VFD (#3779)Dana Robinson2023-10-261-1/+3
| | | | | | When opening a file with the core VFD and a file image, if the file already exists, the file check would leak the POSIX file handle. Fixes GitHub issue #635
* Fix typo in comment (#3775)tbeu2023-10-261-1/+1
|
* Preserve MPI-I/O file hints when fapl is closed (#3755)vchoi-hdfgroup2023-10-252-5/+19
| | | * Fix for issue #3025: Save the MPI info in the file struct so H5Fget_access_plist() can retrieve it from there.
* Fix H5Pset_evict_on_close failing regardless of actual parallel use (#3761)Glenn Song2023-10-242-8/+17
| | | | | Allow H5Pset_evict_on_close to be called regardless of whether a parallel build of HDF5 is being used Fail during file opens if H5Pset_evict_on_close has been set to true on the given File Access Property List and the size of the MPI communicator being used is greater than 1
* Fix some issues with collective metadata reads for chunked datasets (#3716)jhendersonHDF2023-10-249-624/+1252
| | | | | | | | | | Add functions/callbacks for explicit control over chunk index open/close Add functions/callbacks to check if chunk index is open or not so that it can be opened if necessary before temporarily disabling collective metadata reads in the library Add functions/callbacks for requesting loading of additional chunk index metadata beyond the chunk index itself
* Fix hangs during collective I/O with independent metadata writes (#3693)jhendersonHDF2023-10-242-5/+35

* Bump the ros3 VFD cache to 16 MiB (#3759)Dana Robinson2023-10-241-1/+1
|
* Add a simple cache to the ros3 VFD (#3753)Dana Robinson2023-10-231-22/+51
| | | | | | | | | Adds a small cache of the first N bytes of a file opened with the read-only S3 (ros3) VFD, where N is 4kiB or the size of the file, whichever is smaller. This avoids a lot of small I/O operations on file open. Addresses GitHub issue #3381
* Fix buffer overflow in cache debugging code (#3691)jhendersonHDF2023-10-231-20/+84
|
* Add native VOL checks to deprecated functions (#3647)mattjala2023-10-232-58/+145
| | | | | | | * Add native VOL checks to deprecated functions * Remove unneeded native VOL checks * Move native checks to top level calls
* Additional update to the library version matrix for H5Pset_libver_bounds() ↵bmribler2023-10-221-145/+87
| | | | | (#3742) This is the follow-up of PR #3702.
* Update the library version matrix for H5Pset_libver_bounds() (#3702)bmribler2023-10-201-20/+288
| | | | | | | * Fixed #3524 Added 1.12, 1.14, and 1.16 to the table for libver bounds in the H5Pset_libver_bounds docs.
* Add new API function H5Pget_actual_select_io_mode() (#2974)Neil Fortner2023-10-207-46/+362
| | | This function allows the user to determine if the library performed selection I/O, vector I/O, or scalar (legacy) I/O during the last HDF5 operation performed with the provided DXPL. Expanded existing tests to check this functionality.
* Clean up comments. (#3695)H. Joe Lee2023-10-181-41/+35

* Fix invalid memory access in S3 comms (#3681)Dana Robinson2023-10-161-1/+2
| | | | | | | | | In the ros3 VFD, passing an empty string parameter to an internal API call could result in accessing the -1th element of a string. This would cause failures on big-endian systems like s390x. This parameter is now checked before writing to the string. Fixes GitHub #1168
* Suppress MPI_Waitall warnings w/ MPICH (#3680)Dana Robinson2023-10-162-9/+19
| | | | | | | | | MPICH defines MPI_STATUSES_IGNORE (a pointer) to 1, which raises warnings w/ gcc. This is a known issue that the MPICH devs are not going to fix. See here: https://github.com/pmodels/mpich/issues/5687 This fix suppresses those issues w/ gcc
* Remove CANBE_UNUSED() from subfiling VFD (#3678)Dana Robinson2023-10-163-8/+6
| | | | | This macro was an attempt to quiet warnings about release mode unused variables that only appear in asserts. It resolves to a void cast, which doesn't quiet warnings when an assignment has already taken place.
* Fix a strncpy call to use dest size not src (#3677)Dana Robinson2023-10-151-19/+22
| | | | | | | A strncpy call in a path construction call used the size of the src buffer instead of the dest buffer as the limit n. This was switched to use the dest size and properly terminate the string if truncation occurs.
* Remove clang warnings (#3656)H. Joe Lee2023-10-131-2/+2
