Adds HDF5Examples/C/H5PAR/ph5_comm_split.c, showing parallel HDF5 use on a
communicator produced by MPI_Comm_split rather than on MPI_COMM_WORLD.
The example splits MPI_COMM_WORLD by rank parity. The even ranks form a
writer group that collectively creates a dataset with one row per writer
rank, then reopens the file read-only on the same sub-communicator and
verifies what it wrote. The odd ranks stand in for a group with other
responsibilities and make no HDF5 calls at all.
The comments cover the two rules this pattern depends on: MPI_Comm_split is
collective over the parent communicator, so every rank must call it even if
it never opens the file; and once a file is opened with a FAPL carrying a
sub-communicator, every collective HDF5 call on that file is collective over
that sub-communicator alone.
The example runs with any number of MPI ranks.
Refactor the cross-compilation infrastructure to rely on the standard
CMAKE_CROSSCOMPILING_EMULATOR variable instead of the custom
CROSSCOMPILING_PATH environment hack.
Key changes:
- Removed `ENVIRONMENT "${CROSSCOMPILING_PATH}"` from all test definitions.
- Updated custom commands (e.g., H5match_types, H5_gen) to invoke the
emulator explicitly when cross-compiling.
- Updated ConfigureChecks.cmake and HDF5UseFortran.cmake to enable
`try_run` checks when an emulator is defined.
- Added config/toolchain/mingw-w64-x86-64-wine.sh wrapper to automatically
locate MinGW runtime libraries (like libgfortran) for Wine execution.
- Cleaned up toolchain files to remove hardcoded emulator paths, deferring
configuration to the build environment.
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.
Behavior:
Modify HDF5UseFortran.cmake to handle cross-compilation by providing default KINDs and sizes when CMAKE_CROSSCOMPILING is true.
Default values for INTEGER and REAL KINDs and their sizes are set when cross-compiling.
Error messages are adjusted to reflect cross-compilation scenarios.
Logic:
Conditional checks added for CMAKE_CROSSCOMPILING to determine if default values should be used.
Default values include INTEGER KINDs {1,2,4,8,16} and REAL KINDs {4,8,10,16}.
Default sizes for native kinds are set to 4 for INTEGER and REAL, and 8 for DOUBLE PRECISION when cross-compiling.
Misc:
Adjustments to verbose messages to indicate when defaults are used during cross-compilation.
Renamed all HDF5 examples build options from H5EX_* to H5EXAMPLE_* to better distinguish them from library options when building examples alongside the library.
Updated all CMake files, including:
Main examples CMakeLists.txt files
CMake configuration files in config/ directory
CMake preset files
Updated documentation files to reflect new option names
* Remove hbool_t from the public API
This was previously removed from the source code, but the API calls
retained hbool_t in the public API calls. This commit removes
hbool_t from the public APIs.
hbool_t is retained as a typedef for bool in H5public.h so existing
code doesn't break.
This update systematically renames variables across 2.0+ CMake files in the HDF5Examples directory and configuration templates. The goal is to change variables from sounding like build "options" (e.g., HDF5_BUILD_TOOLS, HDF5_ENABLE_PARALLEL) to reflecting library "state" (e.g., what features the installed library provides).
Implemented missing --help/-h, -c, -echo and -shlib/-noshlib options
Added new -nohl option to avoid building and linking against
high-level HDF5 libraries if desired
Implemented adding of HDF5 installation library directory to rpath of
resulting executable/library and added new -norpath option to avoid
this behavior if desired
Added parsing of HDF5_USE_SHLIB environment variable to determine
whether to link against shared or static HDF5 libraries
Added parsing of HDF5_PKG_CONFIG_ARGS environment variable to separate
pkg-config-specific options from compiler-specific options and prevent
conflicts
* Implement support for complex number datatypes
Adds the new datatype class H5T_COMPLEX
Adds the new API function H5Tcomplex_create which creates a complex
number datatype from an ID of a base floating-point datatype
Adds the new feature check macros H5_HAVE_COMPLEX_NUMBERS and
H5_HAVE_C99_COMPLEX_NUMBERS
Adds the new datatype size macros H5_SIZEOF_FLOAT_COMPLEX,
H5_SIZEOF_DOUBLE_COMPLEX and H5_SIZEOF_LONG_DOUBLE_COMPLEX
Adds the new datatype ID macros H5T_NATIVE_FLOAT_COMPLEX,
H5T_NATIVE_DOUBLE_COMPLEX, H5T_NATIVE_LDOUBLE_COMPLEX,
H5T_CPLX_IEEE_F16LE, H5T_CPLX_IEEE_F16BE,
H5T_CPLX_IEEE_F32LE, H5T_CPLX_IEEE_F32BE,
H5T_CPLX_IEEE_F64LE and H5T_CPLX_IEEE_F64BE
Adds hard and soft datatype conversion paths between complex number
datatypes and all the integer and floating-point datatypes, as well as
between other complex number datatypes
Adds a special conversion path between complex number datatypes and
array or compound datatypes where the in-memory layout of data is the
same between the datatypes and data can be converted directly
Adds support for complex number datatypes to the h5dump, h5ls and
h5diff/ph5diff tools. Allows h5dump '-m' option to change floating-point
printing format for float complex and double complex datatypes, as well
as long double complex if it has the same size as double complex
Adds minimal support to the h5watch and h5import tools
Adds support for the predefined complex number datatypes and
H5Tcomplex_create function to the Java wrappers. Also adds initial,
untested support to the JNI for future use with HDFView
Adds support for just the H5T_COMPLEX datatype class to the Fortran
wrappers
Adds support for the predefined complex number datatypes and
H5Tcomplex_create function to the high level library H5LT interface
for use with the H5LTtext_to_dtype and H5LTdtype_to_text functions
Changes some usages of "complex" in the library since it conflicts with
the "complex" keyword from the complex.h header. Also changes various
usages of the word "complex" throughout the library to distinguish
compound datatypes from complex datatypes.
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.
