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
* fix seg fault on frontier/cray
* fix seg fault on frontier/cray
* fix seg fault on frontier/cray
* removed the use of h5pclose_c
* removed the use of h5pclose_c
* Set NVHPC maximum optimization level to -O1 for now
Compiling HDF5 with NVHPC 23.5 - 23.9 results in test failures in
4 different test files that need to be resolved. Since those tests
pass with an optimization level of -O1 (and -O0) and it is currently
unclear whether the test failures are due to issues in HDF5 or issues
in the 'nvc' compiler, set the maximum optimization level for NVHPC
to -O1 until the test failures are resolved.
* Disable nvhpc Java testing in CMake and amend known issues
* Re-enable testing of Autotools nvhpc
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.
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
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
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
* Update Autotools to correctly configure oneAPI
Splits the Intel config files under the Autotools into 'classic'
Intel and oneAPI versions, fixing 'unsupported option' messages.
Also turns off `-check uninit` (new in 2023) in Fortran, which kills
the H5_buildiface program due to false positives.
* Enable Fortran in oneAPI CI workflow
* Turn on Fortran in CMake, update LD_LIBRARY_PATH
* Go back to disabling Fortran w/ Intel
For some reason there's a linking problem w/ Fortran
error while loading shared libraries: libifport.so.5: cannot open shared object file: No such file or directory
Added text to the usage of h5clear to explain that this tool is not
for fixing corrupted files but simply for helping in the inspection
of the damage..
Fixed expected output for testing the modified usage.
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.
