The assertion failure began happening after the collective metadata write pathway in the library was updated to use vector I/O so that parallel-enabled HDF5 Virtual File Drivers (other than the existing MPI I/O VFD) can support collective metadata writes. The assertion failure was fixed by updating collective metadata writes to treat global heap metadata as raw data, as done elsewhere in the library. (JTH - 2023/02/16, GH #2433) Java Library ------------ - Configuration ------------- - Correct the CMake generated pkg-config file The pkg-config file generated by CMake had the order and placement of the libraries wrong. Also added support for debug library names. Changed the order of Libs.private libraries so that dependencies come after dependents. Did not move the compression libraries into Requires.private because there was not a way to determine if the compression libraries had supported pkconfig files. Still recommend that the CMake config file method be used for building projects with CMake.

ADB - 2019/05/07 At present, metadata cache images may not be generated by parallel applications. Parallel applications can read files with metadata cache images, but since this is a collective operation, a deadlock is possible if one or more processes do not participate. CPP ptable test fails on both VS2017 and VS2019 with Intel compiler, JIRA issue: HDFFV-10628. This test will pass with VS2015 with Intel compiler. The subsetting option in ph5diff currently will fail and should be avoided. The subsetting option works correctly in serial h5diff. Several tests currently fail on certain platforms: MPI_TEST-t_bigio fails with spectrum-mpi on ppc64le platforms. MPI_TEST-t_subfiling_vfd and MPI_TEST_EXAMPLES-ph5_subfiling fail with cray-mpich on theta and with XL compilers on ppc64le platforms. MPI_TEST_testphdf5_tldsc fails with cray-mpich 7.7 on cori and theta. Known problems in previous releases can be found in the HISTORY*.txt files in the HDF5 source. Please report any new problems found to help@hdfgroup.org. CMake vs. Autotools installations ================================= While both build systems produce similar results, there are differences. Each system produces the same set of folders on linux (only CMake works on standard Windows); bin, include, lib and share. Autotools places the COPYING and RELEASE.txt file in the root folder, CMake places them in the share folder. The bin folder contains the tools and the build scripts. Additionally, CMake creates dynamic versions of the tools with the suffix "-shared". Autotools installs one set of tools depending on the "--enable-shared" configuration option. build scripts ------------- Autotools: h5c++, h5cc, h5fc CMake: h5c++, h5cc, h5hlc++, h5hlcc The include folder holds the header files and the fortran mod files. CMake places the fortran mod files into separate shared and static subfolders, while Autotools places one set of mod files into the include folder. Because CMake produces a tools library, the header files for tools will appear in the include folder. The lib folder contains the library files, and CMake adds the pkgconfig subfolder with the hdf5*.pc files used by the bin/build scripts created by the CMake build. CMake separates the C interface code from the fortran code by creating C-stub libraries for each Fortran library. In addition, only CMake installs the tools library. The names of the szip libraries are different between the build systems. The share folder will have the most differences because CMake builds include a number of CMake specific files for support of CMake's find_package and support for the HDF5 Examples CMake project. The issues with the gif tool are: HDFFV-10592 CVE-2018-17433 HDFFV-10593 CVE-2018-17436 HDFFV-11048 CVE-2020-10809 These CVE issues have not yet been addressed and are avoided by not building the gif tool by default. Enable building the High-Level tools with these options: autotools: --enable-hlgiftools cmake: HDF5_BUILD_HL_GIF_TOOLS=ON
