This + will allow using those functions without building the high-level + library. The parameters and functionality of the H5D calls are + identical to the H5DO calls. + + The original H5DO high-level API calls have been retained, though + they are now just wrappers for the H5D calls. They are marked as + deprecated and are only available when the library is built with + deprecated functions. New code should use the H5D calls for this + reason. + + As a part of this work, the following symbols from H5Dpublic.h are no + longer used: + + H5D_XFER_DIRECT_CHUNK_WRITE_FLAG_NAME + H5D_XFER_DIRECT_CHUNK_WRITE_FILTERS_NAME + H5D_XFER_DIRECT_CHUNK_WRITE_OFFSET_NAME + H5D_XFER_DIRECT_CHUNK_WRITE_DATASIZE_NAME + H5D_XFER_DIRECT_CHUNK_READ_FLAG_NAME + H5D_XFER_DIRECT_CHUNK_READ_OFFSET_NAME + H5D_XFER_DIRECT_CHUNK_READ_FILTERS_NAME + + And properties with these names are no longer stored in the dataset + transfer property lists. The symbols are still defined in H5Dpublic.h, + but only when the library is built with deprecated symbols. + + (DER - 2018/05/04) + + Configuration: + ------------- + - Add missing USE_110_API_DEFAULT option. + + Option USE_110_API_DEFAULT sets the default version of + versioned APIs. The bin/makevers perl script did not set + the maxidx variable correctly when the 1.10 branch was + created.

Previously, the configure + step would pass but the build itself would fail when it could not + locate the MPI-3 functions used. + + As a result of these new checks, HDF5 can again be built with MPI-2, + but the Parallel Compression feature will be disabled as it relies + on the MPI-3 functions used. + + (JTH - 2018/08/02, HDFFV-10512) + + - User's patches: CVEs + + The following patches have been applied: + + CVE-2018-11202 - NULL pointer dereference was discovered in + H5S_hyper_make_spans in H5Shyper.c (HDFFV-10476) + https://security-tracker.debian.org/tracker/CVE-2018-11202 + https://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2018-11202 + + CVE-2018-11203 - A division by zero was discovered in + H5D__btree_decode_key in H5Dbtree.c (HDFFV-10477) + https://security-tracker.debian.org/tracker/CVE-2018-11203 + https://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2018-11203 + + CVE-2018-11204 - A NULL pointer dereference was discovered in + H5O__chunk_deserialize in H5Ocache.c (HDFFV-10478) + https://security-tracker.debian.org/tracker/CVE-2018-11204 + https://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2018-11204 + + CVE-2018-11206 - An out of bound read was discovered in + H5O_fill_new_decode and H5O_fill_old_decode in H5Ofill.c + (HDFFV-10480) + https://security-tracker.debian.org/tracker/CVE-2018-11206 + https://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2018-11206 + + CVE-2018-11207 - A division by zero was discovered in + H5D__chunk_init in H5Dchunk.c (HDFFV-10481) + https://security-tracker.debian.org/tracker/CVE-2018-11207 + https://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2018-11207 + + (BMR - 2018/7/22, PR#s: 1134 and 1139, + HDFFV-10476, HDFFV-10477, HDFFV-10478, HDFFV-10480, HDFFV-10481) + + - H5Adelete + + H5Adelete failed when deleting the last "large" attribute that + is stored densely via fractal heap/v2 b-tree. + + After removing the attribute, update the ainfo message.

The + library used the incorrect dataspace for each chunk read, causing + the selection used in each chunk to be wrong. + + The bug was not caught during testing because all of the current + tests which do parallel reads of filtered data read all of the data + using an H5S_ALL selection. Several tests were added which exercise + partial parallel reads. + + (JTH - 2018/07/16, HDFFV-10467) + + - A bug was discovered in the parallel library which caused parallel + writes of filtered datasets to trigger an assertion failure in the + file free space manager. + + This occurred when the filter used caused chunks to repeatedly shrink + and grow over the course of several dataset writes. The previous chunk + information, such as the size of the chunk and the offset in the file, + was being cached and not updated after each write, causing the next write + to the chunk to retrieve the incorrect cached information and run into + issues when reallocating space in the file for the chunk. + + (JTH - 2018/07/16, HDFFV-10509) + + - A bug was discovered in the parallel library which caused the + H5D__mpio_array_gatherv() function to allocate too much memory. + + When the function is called with the 'allgather' parameter set + to a non-true value, the function will receive data from all MPI + ranks and gather it to the single rank specied by the 'root' + parameter. However, the bug in the function caused memory for + the received data to be allocated on all MPI ranks, not just the + singular rank specified as the receiver. In some circumstances, + this would cause an application to fail due to the large amounts + of memory being allocated. + + (JTH - 2018/07/16, HDFFV-10467) + + - Error checks in h5stat and when decoding messages + + h5stat exited with seg fault/core dumped when + errors are encountered in the internal library. + + Add error checks and --enable-error-stack option to h5stat. + Add range checks when decoding messages: old fill value, old + layout and refcount. + + (VC - 2018/07/11, HDFFV-10333) + + - If an HDF5 file contains a malformed compound datatype with a + suitably large offset, the type conversion code can run off + the end of the type conversion buffer, causing a segmentation + fault. + + This issue was reported to The HDF Group as issue #CVE-2017-17507. + + NOTE: The HDF5 C library cannot produce such a file. This condition + should only occur in a corrupt (or deliberately altered) file + or a file created by third-party software. + + THE HDF GROUP WILL NOT FIX THIS BUG AT THIS TIME + + Fixing this problem would involve updating the publicly visible + H5T_conv_t function pointer typedef and versioning the API calls + which use it. We normally only modify the public API during + major releases, so this bug will not be fixed at this time. + + (DER - 2018/02/26, HDFFV-10356) + + + Configuration + ------------- + - Applied patches to address Cywin build issues + + There were three issues for Cygwin builds: + - Shared libs were not built. + - The -std=c99 flag caused a SIG_SETMASK undeclared error. + - Undefined errors when buildbing test shared libraries. + + Patches to address these issues were received and incorporated in this version. + + (LRK - 2018/07/18, HDFFV-10475) + + - The --enable-debug/production configure flags are listed as 'deprecated' + when they should really be listed as 'removed'. + + In the autotools overhaul several years ago, we removed these flags and + implemented a new --enable-build-mode= flag. This was done because we + changed the semantics of the modes and didn't want users to silently + be exposed to them. The newer system is also more flexible and us to + add other modes (like 'clean'). + + The --enable-debug/production flags are now listed as removed. + + (DER - 2018/05/31, HDFFV-10505) + + - Moved the location of gcc attribute. + + The gcc attribute(no_sanitize), named as the macro HDF_NO_UBSAN, + was located after the function name. Builds with GCC 7 did not + indicate any problem, but GCC 8 issued errors. Moved the + attribute before the function name, as required. + + (ADB - 2018/05/22, HDFFV-10473) + + - Reworked java test suite into individual JUnit tests. + + Testing the whole suite of java unit tests in a single JUnit run + made it difficult to determine actual failures when tests would fail. + Running each file set of tests individually, allows individual failures + to be diagnosed easier. A side benefit is that tests for optional components + of the library can be disabled if not configured. + + (ADB - 2018/05/16, HDFFV-9739) + + - Converted CMake global commands ADD_DEFINITIONS and INCLUDE_DIRECTORIES + to use target_* type commands. This change modernizes the CMake usage + in the HDF5 library. + + In addition, there is the intention to convert to generator expressions, + where possible. The exception is Fortran FLAGS on Windows Visual Studio. + The HDF macros TARGET_C_PROPERTIES and TARGET_FORTRAN_PROPERTIES have + been removed with this change in usage. + + The additional language (C++ and Fortran) checks have also been localized + to only be checked when that language is enabled. + + (ADB - 2018/05/08) + + + Performance + ------------- + - Revamped internal use of DXPLs, improving performance + + (QAK - 2018/05/20) + + + Fortran + -------- + - Fixed issue with h5fget_obj_count_f and using a file id of H5F_OBJ_ALL_F not + returning the correct count. + + (MSB -

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. + + %%%%1.10.2%%%% HDF5 version 1.10.2 released on 2018-03-29 |
