All sources can be formatted by executing the format target; + make format + + (ADB - 2020/08/24) + + - Add file locking configure and CMake options + + HDF5 1.10.0 introduced a file locking scheme, primarily to help + enforce SWMR setup. Formerly, the only user-level control of the scheme + was via the HDF5_USE_FILE_LOCKING environment variable. + + This change introduces configure-time options that control whether + or not file locking will be used and whether or not the library + ignores errors when locking has been disabled on the file system + (useful on some HPC Lustre installations). + + In both the Autotools and CMake, the settings have the effect of changing + the default property list settings (see the H5Pset/get_file_locking() + entry, below). + + The yes/no/best-effort file locking configure setting has also been + added to the libhdf5.settings file. + + Autotools: + + An --enable-file-locking=(yes|no|best-effort) option has been added. + + yes: Use file locking. + no: Do not use file locking. + best-effort: Use file locking and ignore "disabled" errors. + + CMake: + + Two self-explanatory options have been added: + + HDF5_USE_FILE_LOCKING + HDF5_IGNORE_DISABLED_FILE_LOCKS + + Setting both of these to ON is the equivalent to the Autotools' + best-effort setting. + + NOTE: + The precedence order of the various file locking control mechanisms is: + + 1) HDF5_USE_FILE_LOCKING environment variable (highest) + + 2) H5Pset_file_locking() + + 3) configure/CMake options (which set the property list defaults) + + 4) library defaults (currently best-effort) + + (DER - 2020/07/30, HDFFV-11092) + + - CMake option to link the generated Fortran MOD files into the include + directory. + + The Fortran generation of MOD files by a Fortran compile can produce + different binary files between SHARED and STATIC compiles with different + compilers and/or different platforms. Note that it has been found that + different versions of Fortran compilers will produce incompatible MOD + files. Currently, CMake will locate these MOD files in subfolders of + the include directory and add that path to the Fortran library target + in the CMake config file, which can be used by the CMake find library + process. For other build systems using the binary from a CMake install, + a new CMake configuration can be used to copy the pre-chosen version + of the Fortran MOD files into the install include directory. + + The default will depend on the configuration of + BUILD_STATIC_LIBS and BUILD_SHARED_LIBS: + YES YES Default to SHARED + YES NO Default to STATIC + NO YES Default to SHARED + NO NO Default to SHARED + The defaults can be overridden by setting the config option + HDF5_INSTALL_MOD_FORTRAN to one of NO, SHARED, or STATIC + + (ADB - 2020/07/09, HDFFV-11116) + + - CMake option to use AEC (open source SZip) library instead of SZip + + The open source AEC library is a replacement library for SZip. In + order to use it for hdf5 the libaec CMake source was changed to add + "-fPIC" and exclude test files. Autotools does not build the + compression libraries within hdf5 builds. New option USE_LIBAEC is + required to compensate for the different files produced by AEC build. + + (ADB - 2020/04/22, OESS-65) + + - CMake ConfigureChecks.cmake file now uses CHECK_STRUCT_HAS_MEMBER + + Some handcrafted tests in HDFTests.c has been removed and the CMake + CHECK_STRUCT_HAS_MEMBER module has been used. + + (ADB - 2020/03/24, TRILAB-24) + + - Both build systems use same set of warnings flags + + GNU C, C++ and gfortran warnings flags were moved to files in a config + sub-folder named gnu-warnings. Flags that only are available for a specific + version of the compiler are in files named with that version. + Clang C warnings flags were moved to files in a config sub-folder + named clang-warnings. + Intel C, Fortran warnings flags were moved to files in a config sub-folder + named intel-warnings. + + There are flags in named "error-xxx" files with warnings that may + be promoted to errors. Some source files may still need fixes. + + There are also pairs of files named "developer-xxx" and "no-developer-xxx" + that are chosen by the CMake option:HDF5_ENABLE_DEV_WARNINGS or the + configure option:--enable-developer-warnings. + + In addition, CMake no longer applies these warnings for examples. + + (ADB - 2020/03/24, TRILAB-192) + + - Added test script for file size compare + + If CMake minimum version is at least 3.14, the fileCompareTest.cmake + script will compare file sizes. + + (ADB - 2020/02/24, HDFFV-11036) + + - Update CMake minimum version to 3.12 + + Updated CMake minimum version to 3.12 and added version checks + for Windows features. + + (ADB - 2020/02/05, TRILABS-142) + + - Fixed CMake include properties for Fortran libraries + + Corrected the library properties for Fortran to use the + correct path for the Fortran module files. + + (ADB - 2020/02/04, HDFFV-11012) + + - Added common warnings files for gnu and intel + + Added warnings files to use one common set of flags + during configure for both autotools and CMake build + systems. The initial implementation only affects a + general set of flags for gnu and intel compilers. + + (ADB - 2020/01/17) + + - Added new options to CMake for control of testing + + Added CMake options (default ON); + HDF5_TEST_SERIAL AND/OR HDF5_TEST_PARALLEL + combined with: + HDF5_TEST_TOOLS + HDF5_TEST_EXAMPLES + HDF5_TEST_SWMR + HDF5_TEST_FORTRAN + HDF5_TEST_CPP + HDF5_TEST_JAVA + + (ADB - 2020/01/15, HDFFV-11001) + + - Added Clang sanitizers to CMake for analyzer support if compiler is clang. + + Added CMake code and files to execute the Clang sanitizers if + HDF5_ENABLE_SANITIZERS is enabled and the USE_SANITIZER option + is set to one of the following: + Address + Memory + MemoryWithOrigins + Undefined + Thread + Leak + 'Address;Undefined' + + (ADB - 2019/12/12, TRILAB-135) + + - Update CMake for VS2019 support + + CMake added support for VS2019 in version 3.15. Changes to the CMake + generator setting required changes to scripts. Also updated version + references in CMake files as necessary. + + (ADB - 2019/11/18, HDFFV-10962) + + - Update CMake options to match new autotools options + + Add configure options (autotools - CMake): + enable-asserts HDF5_ENABLE_ASSERTS + enable-symbols HDF5_ENABLE_SYMBOLS + enable-profiling HDF5_ENABLE_PROFILING + enable-optimization HDF5_ENABLE_OPTIMIZATION + In addition NDEBUG is no longer forced defined and relies on the CMake + process. + + (ADB - 2019/10/07, HDFFV-100901, HDFFV-10637, TRILAB-97) + + + Library: + -------- + - Adds new file driver-level memory copy operation for + "ctl" callback and updates compact dataset I/O routines + to utilize it + + When accessing an HDF5 file with a file driver that uses + memory allocated in special ways (e.g., without standard + library's `malloc`), a crash could be observed when HDF5 + tries to perform `memcpy` operations on such a memory + region. + + These changes add a new H5FD_FEAT_MEMMANAGE VFD feature + flag, which, if specified as supported by a VFD, will + inform HDF5 that the VFD either uses special memory + management routines or wishes to perform memory management + in a specific way. Therefore, this flag instructs HDF5 to + ask the file driver to perform memory management for + certain operations. + + These changes also introduce a new "ctl" callback + operation identified by the H5FD_CTL__MEM_COPY op code. + This operation simply asks a VFD to perform a memory copy. + The arguments to this operation are passed to the "ctl" + callback's "input" parameter as a pointer to a struct + defined as: + + struct H5FD_ctl_memcpy_args_t { + void * dstbuf; /**< Destination buffer */ + hsize_t dst_off; /**< Offset within destination buffer */ + const void *srcbuf; /**< Source buffer */ + hsize_t src_off; /**< Offset within source buffer */ + size_t len; /**< Length of data to copy from source buffer */ + } H5FD_ctl_memcpy_args_t; + + Further, HDF5's compact dataset I/O routines were + identified as a problematic area that could cause a crash + for VFDs that make use of special memory management. Those + I/O routines were therefore updated to make use of this new + "ctl" callback operation in order to ask the underlying + file driver to correctly handle memory copies. + + (JTH - 2021/09/28) + + - Adds new "ctl" callback to VFD H5FD_class_t structure + with the following prototype: + + herr_t (*ctl)(H5FD_t *file, uint64_t op_code, + uint64_t flags, const void *input, + void **output); + + This newly-added "ctl" callback allows Virtual File + Drivers to intercept and handle arbitrary operations + identified by an operation code. Its parameters are + as follows: + + `file` [in] - A pointer to the file to be operated on + `op_code` [in] - The operation code identifying the + operation to be performed + `flags` [in] - Flags governing the behavior of the + operation performed (see H5FDpublic.h + for a list of valid flags) + `input` [in] - A pointer to arguments passed to the + VFD performing the operation + `output` [out] - A pointer for the receiving VFD to + use for output from the operation + + (JRM - 2021/08/16) + + - Change how the release part of version, in major.minor.release is checked + for compatibility + + The HDF5 library uses a function, H5check_version, to check that + the version defined in the header files, which is used to compile an + application is compatible with the version codified in the library, which + the application loads at runtime. This previously required an exact match + or the library would print a warning, dump the build settings and then + abort or continue. An environment variable controlled the logic. + + Now the function first checks that the library release version, in + major.minor.release, is not older than the version in the headers. + Secondly, if the release version is different, it checks if either + the library version or the header version is in the exception list, in + which case the release part of version, in major.minor.release, must + be exact. An environment variable still controls the logic. + + (ADB - 2021/07/27) + + - gcc warning suppression macros were moved out of H5public.h + + The HDF5 library uses a set of macros to suppress warnings on gcc. + These warnings were originally located in H5public.h so that the + multi VFD (which only uses public headers) could also make use of them + but internal macros should not be publicly exposed like this. + + These macros have now been moved to H5private.h. Pending future multi + VFD refactoring, the macros have been duplicated in H5FDmulti.c to + suppress the format string warnings there. + + (DER - 2021/06/03) + + - H5Gcreate1() now rejects size_hint parameters larger than UINT32_MAX + + The size_hint value is ultimately stored in a uint32_t struct field, + so specifying a value larger than this on a 64-bit machine can cause + undefined behavior including crashing the system. + + The documentation for this API call was also incorrect, stating that + passing a negative value would cause the library to use a default + value. Instead, passing a "negative" value actually passes a very large + value, which is probably not what the user intends and can cause + crashes on 64-bit systems. + + The Doxygen documentation has been updated and passing values larger + than UINT32_MAX for size_hint will now produce a normal HDF5 error. + + (DER - 2021/04/29, HDFFV-11241) + + + - H5Pset_fapl_log() no longer crashes when passed an invalid fapl ID + + When passed an invalid fapl ID, H5Pset_fapl_log() would usually + segfault when attempting to free an uninitialized pointer in the error + handling code. This behavior is more common in release builds or + when the memory sanitization checks were not selected as a build + option. + + The pointer is now correctly initialized and the API call now + produces a normal HDF5 error when fed an invalid fapl ID. + + (DER - 2021/04/28, HDFFV-11240) + + - Fixes a segfault when H5Pset_mdc_log_options() is called multiple times + + The call incorrectly attempts to free an internal copy of the previous + log location string, which causes a segfault. This only happens + when the call is invoked multiple times on the same property list. + On the first call to a given fapl, the log location is set to NULL so + the segfault does not occur. + + The string is now handled properly and the segfault no longer occurs. + + (DER - 2021/04/27, HDFFV-11239) + + - HSYS_GOTO_ERROR now emits the results of GetLastError() on Windows + + HSYS_GOTO_ERROR is an internal macro that is used to produce error + messages when system calls fail. These strings include errno and the + the associated strerror() value, which are not particularly useful + when a Win32 API call fails. + + On Windows, this macro has been updated to include the result of + GetLastError(). When a system call fails on Windows, usually only + one of errno and GetLastError() will be useful, however we emit both + for the user to parse. The Windows error message is not emitted as + it would be awkward to free the FormatMessage() buffer given the + existing HDF5 error framework. Users will have to look up the error + codes in MSDN. + + The format string on Windows has been changed from: + + "%s, errno = %d, error message = '%s'" + + to: + + "%s, errno = %d, error message = '%s', Win32 GetLastError() = %"PRIu32"" + + for those inclined to parse it for error values. + + (DER - 2021/03/21) + + - File locking now works on Windows + + Since version 1.10.0, the HDF5 library has used a file locking scheme + to help enforce one reader at a time accessing an HDF5 file, which can + be helpful when setting up readers and writers to use the single- + writer/multiple-readers (SWMR) access pattern. + + In the past, this was only functional on POSIX systems where flock() or + fcntl() were present. Windows used a no-op stub that always succeeded. + + HDF5 now uses LockFileEx() and UnlockFileEx() to lock the file using the + same scheme as POSIX systems.

Consequently, a trailing semicolon - is now required to end the `while` statement. Previously, a trailing - semi would work, but was not mandatory. This change was made to allow - clang-format to correctly format the source code. - - (SAM - 2021/03/03) - - - Improved performance of H5Sget_select_elem_pointlist - - Modified library to cache the point after the last block of points - retrieved by H5Sget_select_elem_pointlist, so a subsequent call to the - same function to retrieve the next block of points from the list can - proceed immediately without needing to iterate over the point list. - - (NAF - 2021/01/19) - - - Replaced H5E_ATOM with H5E_ID in H5Epubgen.h - - The term "atom" is archaic and not in line with current HDF5 library - terminology, which uses "ID" instead. "Atom" has mostly been purged - from the library internals and this change removes H5E_ATOM from - the H5Epubgen.h (exposed via H5Epublic.h) and replaces it with - H5E_ID. - - (DER - 2020/11/24, HDFFV-11190) - - - Add a new public function H5Ssel_iter_reset - - This function resets a dataspace selection iterator back to an - initial state so that it may be used for iteration once more. - This can be useful when needing to iterate over a selection - multiple times without having to repeatedly create/destroy - a selection iterator for that dataspace selection. - - (JTH - 2020/09/18) - - - Remove HDFS VFD stubs - - The original implementation of the HDFS VFD included non-functional - versions of the following public API calls when the HDFS VFD is - not built as a part of the HDF5 library: - - * H5FD_hdfs_init() - * H5Pget_fapl_hdfs() - * H5Pset_fapl_hdfs() - - They will remain present in HDF5 1.10 and HDF5 1.12 releases - for binary compatibility purposes but have been removed as of 1.14.0. - - Note that this has nothing to do with the real HDFS VFD API calls - that are fully functional when the HDFS VFD is configured and built. - - We simply changed: - - #ifdef LIBHDFS - <real API call> - #else - <useless stub> - #endif - - to: - - #ifdef LIBHDFS - <real API call> - #endif - - Which is how the other optional VFDs are handled. - - (DER - 2020/08/27) - - - Add Mirror VFD - - Use TCP/IP sockets to perform write-only (W/O) file I/O on a remote - machine. Must be used in conjunction with the Splitter VFD. - - (JOS - 2020/03/13, TBD) - - - Add Splitter VFD - - Maintain separate R/W and W/O channels for "concurrent" file writes - to two files using a single HDF5 file handle. - - (JOS - 2020/03/13, TBD) - - - Refactored public exposure of haddr_t type in favor of "object tokens" - - To better accommodate HDF5 VOL connectors where "object addresses in a file" - may not make much sense, the following changes were made to the library: - - * Introduced new H5O_token_t "object token" type, which represents a - unique and permanent identifier for referencing an HDF5 object within - a container; these "object tokens" are meant to replace object addresses. - Along with the new type, a new H5Oopen_by_token API call was introduced - to open an object by a token, similar to how object addresses were - previously used with H5Oopen_by_addr. - - * Introduced new H5Lget_info2, H5Lget_info_by_idx2, H5Literate2, H5Literate_by_name2, - H5Lvisit2 and H5Lvisit_by_name2 API calls, along with their associated H5L_info2_t - struct and H5L_iterate2_t callback function, which work with the newly-introduced - object tokens, instead of object addresses. The original functions have been - renamed to version 1 functions and are deprecated in favor of the new version 2 - functions. The H5L_info_t and H5L_iterate_t types have been renamed to version 1 - types and are now deprecated in favor of their version 2 counterparts. For each of - the functions and types, compatibility macros take place of the original symbols. - - * Introduced new H5Oget_info3, H5Oget_info_by_name3, H5Oget_info_by_idx3, - H5Ovisit3 and H5Ovisit_by_name3 API calls, along with their associated H5O_info2_t - struct and H5O_iterate2_t callback function, which work with the newly-introduced - object tokens, instead of object addresses. The version 2 functions are now - deprecated in favor of the version 3 functions. The H5O_info_t and H5O_iterate_t - types have been renamed to version 1 types and are now deprecated in favor of their - version 2 counterparts. For each, compatibility macros take place of the original - symbols. - - * Introduced new H5Oget_native_info, H5Oget_native_info_by_name and - H5Oget_native_info_by_idx API calls, along with their associated H5O_native_info_t - struct, which are used to retrieve the native HDF5 file format-specific information - about an object. This information (such as object header info and B-tree/heap info) - has been removed from the new H5O_info2_t struct so that the more generic - H5Oget_info(_by_name/_by_idx)3 routines will not try to retrieve it for non-native - VOL connectors. - - * Added new H5Otoken_cmp, H5Otoken_to_str and H5Otoken_from_str routines to compare - two object tokens, convert an object token into a nicely-readable string format and - to convert an object token string back into a real object token, respectively. - - (DER, QAK, JTH - 2020/01/16) - - - Add new public function H5Sselect_adjust. - - This function shifts a dataspace selection by a specified logical offset - within the dataspace extent. This can be useful for VOL developers to - implement chunked datasets. + Parallel Library: + ----------------- + - Several improvements to parallel compression feature, including: - (NAF - 2019/11/18) + * Improved support for collective I/O (for both writes and reads) - - Add new public function H5Sselect_project_intersection. + * Significant reduction of memory usage for the feature as a whole - This function computes the intersection between two dataspace selections - and projects that intersection into a third selection. This can be useful - for VOL developers to implement chunked or virtual datasets. + * Reduction of copying of application data buffers passed to H5Dwrite - (NAF - 2019/11/13, ID-148) + * Addition of support for incremental file space allocation for filtered + datasets created in parallel. Incremental file space allocation is the + default for these types of datasets (early file space allocation is + also still supported), while early file space allocation is still the + default (and only supported allocation time) for unfiltered datasets + created in parallel. Incremental file space allocation should help with + parallel HDF5 applications that wish to use fill values on filtered + datasets, but would typically avoid doing so since dataset creation in + parallel would often take an excessive amount of time. Since these + datasets previously used early file space allocation, HDF5 would + allocate space for and write fill values to every chunk in the dataset + at creation time, leading to noticeable overhead. Instead, with + incremental file space allocation, allocation of file space for chunks + and writing of fill values to those chunks will be delayed until each + individual chunk is initially written to. - - Add new public function H5VLget_file_type. + * Addition of support for HDF5's "don't filter partial edge chunks" flag + (https://portal.hdfgroup.org/display/HDF5/H5P_SET_CHUNK_OPTS) - This function returns a datatype equivalent to the supplied datatype but - with the location set to be in the file. This datatype can then be used - with H5Tconvert to convert data between file and in-memory representation. - This function is intended for use only by VOL connector developers. + * Addition of proper support for HDF5 fill values with the feature - (NAF - 2019/11/08, ID-127) + * Addition of 'H5_HAVE_PARALLEL_FILTERED_WRITES' macro to H5pubconf.h + so HDF5 applications can determine at compile-time whether the feature + is available + * Addition of simple examples (ph5_filtered_writes.c and + ph5_filtered_writes_no_sel.c) under examples directory to demonstrate + usage of the feature - Parallel Library: - ----------------- - - + * Improved coverage of regression testing for the feature + (JTH - 2022/2/23) Fortran Library: ---------------- - - H5Fget_name_f fixed to handle correctly trailing whitespaces and - newly allocated buffers. - - (MSB - 2021/08/30, github-826,972) - - - Add wrappers for H5Pset/get_file_locking() API calls - - h5pget_file_locking_f() - h5pset_file_locking_f() - - See the configure option discussion for HDFFV-11092 (above) for more - information on the file locking feature and how it's controlled. + - - (DER - 2020/07/30, HDFFV-11092) C++ Library: ------------ - - Add wrappers for H5Pset/get_file_locking() API calls - - FileAccPropList::setFileLocking() - FileAccPropList::getFileLocking() - - See the configure option discussion for HDFFV-11092 (above) for more - information on the file locking feature and how it's controlled. - - (DER - 2020/07/30, HDFFV-11092) + - Java Library: ------------- - - Replaced HDF5AtomException with HDF5IdException - - Since H5E_ATOM changed to H5E_ID in the C library, the Java exception - that wraps the error category was also renamed. Its functionality - remains unchanged aside from the name. - - (See also the HDFFV-11190 note in the C library section) - - (DER - 2020/11/24, HDFFV-11190) - - - Added new H5S functions. - - H5Sselect_copy, H5Sselect_shape_same, H5Sselect_adjust, - H5Sselect_intersect_block, H5Sselect_project_intersection, - H5Scombine_hyperslab, H5Smodify_select, H5Scombine_select - wrapper functions added. - - (ADB - 2020/10/27, HDFFV-10868) - - - Add wrappers for H5Pset/get_file_locking() API calls - - H5Pset_file_locking() - H5Pget_use_file_locking() - H5Pget_ignore_disabled_file_locking() - - Unlike the C++ and Fortran wrappers, there are separate getters for the - two file locking settings, each of which returns a boolean value. - - See the configure option discussion for HDFFV-11092 (above) for more - information on the file locking feature and how it's controlled. - - (DER - 2020/07/30, HDFFV-11092) - - - Added ability to test java library with VOLs. - - Created a new CMake script that combines the java and vol test scripts. - - (ADB - 2020/02/03, HDFFV-10996) - - - Tests fail for non-English locales. - - In the JUnit tests with a non-English locale, only the part before - the decimal comma is replaced by XXXX and this leads to a comparison - error. Changed the regex for the Time substitution. - - (ADB - 2020/01/09, HDFFV-10995) + - Tools: ------ - - Refactored the perform tools and removed depends on test library. - - Moved the perf and h5perf tools from tools/test/perform to - tools/src/h5perf so that they can be installed. This required - that the test library dependency be removed by copying the - needed functions from h5test.c. - The standalone scripts and other perform tools remain in the - tools/test/perform folder. - - (ADB - 2021/08/10) - - - Removed partial long exceptions - - Some of the tools accepted shortened versions of the long options - (ex: --datas instead of --dataset). These were implemented inconsistently, - are difficult to maintian, and occasionally block useful long option - names. These partial long options have been removed from all the tools. - - (DER - 2021/08/03) - - - h5repack added help text for user-defined filters. - - Added help text line that states the valid values of the filter flag - for user-defined filters; - filter_flag: 1 is OPTIONAL or 0 is MANDATORY - - (ADB - 2021/01/14, HDFFV-11099) - - - Added h5delete tool - - Deleting HDF5 storage when using the VOL can be tricky when the VOL - does not create files. The h5delete tool is a simple wrapper around - the H5Fdelete() API call that uses the VOL specified in the - HDF5_VOL_CONNECTOR environment variable to delete a "file". If - the call to H5Fdelete() fails, the tool will attempt to use - the POSIX remove(3) call to remove the file. - - Note that the HDF5 library does currently have support for - H5Fdelete() in the native VOL connector. - - (DER - 2020/12/16) - - - h5repack added options to control how external links are handled. - - Currently h5repack preserves external links and cannot copy and merge - data from the external files. Two options, merge and prune, were added to - control how to merge data from an external link into the resulting file. - --merge Follow external soft link recursively and merge data. - --prune Do not follow external soft links and remove link. - --merge --prune Follow external link, merge data and remove dangling link. - - (ADB - 2020/08/05, HDFFV-9984) - - - h5repack was fixed to repack the reference attributes properly. - The code line that checks if the update of reference inside a compound - datatype is misplaced outside the code block loop that carries out the - check. In consequence, the next attribute that is not the reference - type was repacked again as the reference type and caused the failure of - repacking. The fix is to move the corresponding code line to the correct - code block. - - (KY -2020/02/07, HDFFV-11014) - - - h5diff was updated to use the new reference APIs. - - h5diff uses the new reference APIs to compare references. - Attribute references can also be compared. - - (ADB - 2019/12/19, HDFFV-10980) - - - h5dump and h5ls were updated to use the new reference APIs. - - The tools library now use the new reference APIs to inspect a - file. Also the DDL spec was updated to reflect the format - changes produced with the new APIs. The export API and support - functions in the JNI were updated to match. - - (ADB - 2019/12/06, HDFFV-10876 and HDFFV-10877) + - High-Level APIs: ---------------- - - added set/get for unsigned long long attributes - - The attribute writing high-level API has been expanded to include - public set/get functions for ULL attributes, analogously to the - existing set/get for other types. + - - (AF - 2021/09/08) C Packet Table API: ------------------- - + Internal header file: --------------------- - + Documentation: -------------- - + Support for new platforms, languages and compilers ================================================== - + Bug Fixes since HDF5-1.12.0 release =================================== Library ------- - - Fixed an H5Pget_filter_by_id1/2() assert w/ out of range filter IDs - - Both H5Pget_filter_by_id1 and 2 did not range check the filter ID, which - could trip as assert in debug versions of the library. The library now - returns a normal HDF5 error when the filter ID is out of range. - - (DER - 2021/11/23, HDFFV-11286) - - - Fixed an issue with collective metadata reads being permanently disabled - after a dataset chunk lookup operation. This would usually cause a - mismatched MPI_Bcast and MPI_ERR_TRUNCATE issue in the library for - simple cases of H5Dcreate() -> H5Dwrite() -> H5Dcreate(). - - (JTH - 2021/11/08, HDFFV-11090) - - - Fixed cross platform incompatibility of references within variable length - types - - Reference types within variable length types previously could not be - read on a platform with different endianness from where they were - written. Fixed so cross platform portability is restored. - - (NAF - 2021/09/30) - - - Detection of simple data transform function "x" - - In the case of the simple data transform function "x" the (parallel) - library recognizes this is the same as not applying this data transform - function. This improves the I/O performance. In the case of the parallel - library, it also avoids breaking to independent I/O, which makes it - possible to apply a filter when writing or reading data to or from - the HDF5 file. - - (JWSB - 2021/09/13) - - - Fixed an invalid read and memory leak when parsing corrupt file space - info messages - - When the corrupt file from CVE-2020-10810 was parsed by the library, - the code that imports the version 0 file space info object header - message to the version 1 struct could read past the buffer read from - the disk, causing an invalid memory read. Not catching this error would - cause downstream errors that eventually resulted in a previously - allocated buffer to be unfreed when the library shut down. In builds - where the free lists are in use, this could result in an infinite loop - and SIGABRT when the library shuts down. - - We now track the buffer size and raise an error on attempts to read - past the end of it. - - (DER - 2021/08/12, HDFFV-11053) - - - - Fixed CVE-2018-14460 - - The tool h5repack produced a segfault when the rank in dataspace - message was corrupted, causing invalid read while decoding the - dimension sizes. - - The problem was fixed by ensuring that decoding the dimension sizes - and max values will not go beyong the end of the buffer. - - (BMR - 2021/05/12, HDFFV-11223) - - - Fixed CVE-2018-11206 - - The tool h5dump produced a segfault when the size of a fill value - message was corrupted and caused a buffer overflow. - - The problem was fixed by verifying the fill value's size - against the buffer size before attempting to access the buffer. - - (BMR - 2021/03/15, HDFFV-10480) - - - Fixed CVE-2018-14033 (same issue as CVE-2020-10811) - - The tool h5dump produced a segfault when the storage size message - was corrupted and caused a buffer overflow. - - The problem was fixed by verifying the storage size against the - buffer size before attempting to access the buffer. - - (BMR - 2021/03/15, HDFFV-11159/HDFFV-11049) - - - Remove underscores on header file guards - - Header file guards used a variety of underscores at the beginning of the define. - - Removed all leading (some trailing) underscores from header file guards. - - (ADB - 2021/03/03, #361) - - - Fixed a segmentation fault - - A segmentation fault occurred with a Mathworks corrupted file. - - A detection of accessing a null pointer was added to prevent the problem. - - (BMR - 2021/02/19, HDFFV-11150) - - - Fixed issue with MPI communicator and info object not being - copied into new FAPL retrieved from H5F_get_access_plist - - Added logic to copy the MPI communicator and info object into - the output FAPL. MPI communicator is retrieved from the VFD, while - the MPI info object is retrieved from the file's original FAPL. - - (JTH - 2021/02/15, HDFFV-11109) - - - Fixed problems with vlens and refs inside compound using - H5VLget_file_type() - - Modified library to properly ref count H5VL_object_t structs and only - consider file vlen and reference types to be equal if their files are - the same. - - (NAF - 2021/01/22) - - - Fixed CVE-2018-17432 - - The tool h5repack produced a segfault on a corrupted file which had - invalid rank for scalar or NULL datatype. - - The problem was fixed by modifying the dataspace encode and decode - functions to detect and report invalid rank. h5repack now fails - with an error message for the corrupted file. - - (BMR - 2020/10/26, HDFFV-10590) - - - Creation of dataset with optional filter - - When the combination of type, space, etc doesn't work for filter - and the filter is optional, it was supposed to be skipped but it was - not skipped and the creation failed. - - Allowed the creation of the dataset in such a situation. - - (BMR - 2020/08/13, HDFFV-10933) - - - Explicitly declared dlopen to use RTLD_LOCAL - - dlopen documentation states that if neither RTLD_GLOBAL nor - RTLD_LOCAL are specified, then the default behavior is unspecified. - The default on linux is usually RTLD_LOCAL while macos will default - to RTLD_GLOBAL. - - (ADB - 2020/08/12, HDFFV-11127) - - - H5Sset_extent_none() sets the dataspace class to H5S_NO_CLASS which - causes asserts/errors when passed to other dataspace API calls. - - H5S_NO_CLASS is an internal class value that should not have been - exposed via a public API call. - - In debug builds of the library, this can cause assert() function to - trip. In non-debug builds, it will produce normal library errors. - - The new library behavior is for H5Sset_extent_none() to convert - the dataspace into one of type H5S_NULL, which is better handled - by the library and easier for developers to reason about. - - (DER - 2020/07/27, HDFFV-11027) - - - Fixed issues CVE-2018-13870 and CVE-2018-13869 - - When a buffer overflow occurred because a name length was corrupted - and became very large, h5dump crashed on memory access violation. - - A check for reading pass the end of the buffer was added to multiple - locations to prevent the crashes and h5dump now simply fails with an - error message when this error condition occurs. - - (BMR - 2020/07/22, HDFFV-11120 and HDFFV-11121) - - - Fixed the segmentation fault when reading attributes with multiple threads - - It was reported that the reading of attributes with variable length string - datatype will crash with segmentation fault particularly when the number of - threads is high (>16 threads). The problem was due to the file pointer that - was set in the variable length string datatype for the attribute. That file - pointer was already closed when the attribute was accessed. - - The problem was fixed by setting the file pointer to the current opened file pointer - when the attribute was accessed. Similar patch up was done before when reading - dataset with variable length string datatype. - - (VC - 2020/07/13, HDFFV-11080) - - - Fixed CVE-2020-10810 - - The tool h5clear produced a segfault during an error recovery in - the superblock decoding. An internal pointer was reset to prevent - further accessing when it is not assigned with a value. - - (BMR - 2020/06/29, HDFFV-11053) - - - Fixed CVE-2018-17435 - - The tool h52gif produced a segfault when the size of an attribute - message was corrupted and caused a buffer overflow. - - The problem was fixed by verifying the attribute message's size - against the buffer size before accessing the buffer. h52gif was - also fixed to display the failure instead of silently exiting - after the segfault was eliminated. - - (BMR - 2020/06/19, HDFFV-10591) + - Fixed a metadata cache bug when resizing a pinned/protected cache entry + + When resizing a pinned/protected cache entry, the metadata + cache code previously would wait until after resizing the + entry to attempt to log the newly-dirtied entry. This would + cause H5C_resize_entry to mark the entry as dirty and make + H5AC_resize_entry think that it doesn't need to add the + newly-dirtied entry to the dirty entries skiplist. + + Thus, a subsequent H5AC__log_moved_entry would think it + needs to allocate a new entry for insertion into the dirty + entry skip list, since the entry doesn't exist on that list. + This causes an assertion failure, as the code to allocate a + new entry assumes that the entry is not dirty. + + (JRM - 2022/02/28) + + - Issue #1436 identified a problem with the H5_VERS_RELEASE check in the + H5check_version function. + + Investigating the original fix, #812, we discovered some inconsistencies + with a new block added to check H5_VERS_RELEASE for incompatibilities. + This new block was not using the new warning text dealing with the + H5_VERS_RELEASE check and would cause the warning to be duplicated. + + By removing the H5_VERS_RELEASE argument in the first check for + H5_VERS_MAJOR and H5_VERS_MINOR, the second check would only check + the H5_VERS_RELEASE for incompatible release versions. This adheres + to the statement that except for the develop branch, all release versions + in a major.minor maintenance branch should be compatible.

However, this was only a partial solution + that wasn't granular enough. + + This change now unifies the handling of the file-global flag and the + API context-level flag for collective metadata reads in order to + simplify querying of the true status of collective metadata reads. Thus, + collective metadata reads are once again enabled for chunked dataset + raw data I/O, but manually controlled at places where some processing + occurs on MPI rank 0 only and would cause issues when collective + metadata reads are enabled. + + (JTH - 2021/11/16, HDFFV-10501/HDFFV-10562) + + - Fixed several potential MPI deadlocks in library failure conditions + + In the parallel library, there were several places where MPI rank 0 + could end up skipping past collective MPI operations when some failure + occurs in rank 0-specific processing.

In addition to fixing that function, added new - java tests for using the new APIs. - - (ADB - 2021/02/16, HDFFV-11212) - - - The H5FArray.java class, in which virtually the entire execution time - is spent using the HDFNativeData method that converts from an array - of bytes to an array of the destination Java type. - - 1. Convert the entire byte array into a 1-d array of the desired type, - rather than performing 1 conversion per row; - 2. Use the Java Arrays method copyOfRange to grab the section of the - array from (1) that is desired to be inserted into the destination array. - - (PGT,ADB - 2020/12/13, HDFFV-10865) - - - Added ability to test java library with VOLs. - - Created a new CMake script that combines the java and vol test scripts. - - (ADB - 2020/02/03, HDFFV-10996) - - - Tests fail for non-English locales. - - In the JUnit tests with a non-English locale, only the part before - the decimal comma is replaced by XXXX and this leads to a comparison - error. Changed the regex for the Time substitution. - - (ADB - 2020/01/09, HDFFV-10995) + - Configuration ------------- - - Corrected path searched by CMake find_package command - - The install path for cmake find_package files had been changed to use - "share/cmake" - for all platforms. However the trailing "hdf5" directory was not removed. - This "hdf5" additional directory has been removed. - - (ADB - 2021/09/27) - - - Corrected pkg-config compile script - - It was discovered that the position of the "$@" argument for the command - in the compile script may fail on some platforms and configurations. The - position of the "$@"command argument was moved before the pkg-config sub command. - - (ADB - 2021/08/30) - - - Fixed CMake C++ compiler flags - - A recent refactoring of the C++ configure files accidently removed the - file that executed the enable_language command for C++ needed by the - HDFCXXCompilerFlags.cmake file. Also updated the intel warnings files, - including adding support for windows platforms. - - (ADB - 2021/08/10) - - - Better support for libaec (open-source Szip library) in CMake - - Implemented better support for libaec 1.0.5 (or later) library. This version - of libaec contains improvements for better integration with HDF5. Furthermore, - the variable USE_LIBAEC_STATIC has been introduced to allow to make use of - static version of libaec library. Use libaec_DIR or libaec_ROOT to set - the location in which libaec can be found. - - Be aware, the Szip library of libaec 1.0.4 depends on another library within - libaec library. This dependency is not specified in the current CMake - configuration which means that one can not use the static Szip library of - libaec 1.0.4 when building HDF5. This has been resolved in libaec 1.0.5. - - (JWSB - 2021/06/22) - - - Refactor CMake configure for Fortran - - The Fortran configure tests for KINDs reused a single output file that was - read to form the Integer and Real Kinds defines. However, if config was run - more then once, the CMake completed variable prevented the tests from executing - again and the last value saved in the file was used to create the define. - Creating separate files for each KIND solved the issue. - - In addition the test for H5_PAC_C_MAX_REAL_PRECISION was not pulling in - defines for proper operation and did not define H5_PAC_C_MAX_REAL_PRECISION - correctly for a zero value. This was fixed by supplying the required defines. - In addition it was moved from the Fortran specific HDF5UseFortran.camke file - to the C centric ConfigureChecks.cmake file. - - (ADB - 2021/06/03) - - - Move emscripten flag to compile flags - - The emscripten flag, -O0, was removed from target_link_libraries command - to the correct target_compile_options command. - - (ADB - 2021/04/26 HDFFV-11083) - - - Remove arbitrary warning flag groups from CMake builds - - The arbitrary groups were created to reduce the quantity of warnings being - reported that overwhelmed testing report systems. Considerable work has - been accomplished to reduce the warning count and these arbitrary groups - are no longer needed. - Also the default for all warnings, HDF5_ENABLE_ALL_WARNINGS, is now ON. - - Visual Studio warnings C4100, C4706, and C4127 have been moved to - developer warnings, HDF5_ENABLE_DEV_WARNINGS, and are disabled for normal builds. - - (ADB - 2021/03/22, HDFFV-11228) - - - Reclassify CMake messages, to allow new modes and --log-level option - - CMake message commands have a mode argument. By default, STATUS mode - was chosen for any non-error message. CMake version 3.15 added additional - modes, NOTICE, VERBOSE, DEBUG and TRACE. All message commands with a mode - of STATUS were reviewed and most were reclassified as VERBOSE. The new - mode was protected by a check for a CMake version of at least 3.15. If CMake - version 3.17 or above is used, the user can use the command line option - of "--log-level" to further restrict which message commands are displayed. - - (ADB - 2021/01/11, HDFFV-11144) - - - Fixes Autotools determination of the stat struct having an st_blocks field - - A missing parenthesis in an autoconf macro prevented building the test - code used to determine if the stat struct contains the st_blocks field. - Now that the test functions correctly, the H5_HAVE_STAT_ST_BLOCKS #define - found in H5pubconf.h will be defined correctly on both the Autotools and - CMake. This #define is only used in the tests and does not affect the - HDF5 C library. - - (DER - 2021/01/07, HDFFV-11201) - - - Add missing ENV variable line to hdfoptions.cmake file - - Using the build options to use system SZIP/ZLIB libraries need to also - specify the library root directory. Setting the {library}_ROOT ENV - variable was added to the hdfoptions.cmake file. - - (ADB - 2020/10/19 HDFFV-11108) + - Tools ----- - - Changed how h5dump and h5ls identify long double. - - Long double support is not consistent across platforms. Tools will always - identify long double as 128-bit [little/big]-endian float nn-bit precision. - New test file created for datasets with attributes for float, double and - long double. In addition any unknown integer or float datatype will now - also show the number of bits for precision. - These files are also used in the java tests. - - (ADB - 2021/03/24, HDFFV-11229,HDFFV-11113) - - - Fixed tools argument parsing. - - Tools parsing used the length of the option from the long array to match - the option from the command line. This incorrectly matched a shorter long - name option that happened to be a subset of another long option. - Changed to match whole names. - - (ADB - 2021/01/19, HDFFV-11106) - - - The tools library was updated by standardizing the error stack process. - - General sequence is: - h5tools_setprogname(PROGRAMNAME); - h5tools_setstatus(EXIT_SUCCESS); - h5tools_init(); - ... process the command-line (check for error-stack enable) ... - h5tools_error_report(); - ... (do work) ... - h5diff_exit(ret); - - (ADB - 2020/07/20, HDFFV-11066) - - - h5diff fixed a command line parsing error. - - h5diff would ignore the argument to -d (delta) if it is smaller than DBL_EPSILON. - The macro H5_DBL_ABS_EQUAL was removed and a direct value comparision was used. - - (ADB - 2020/07/20, HDFFV-10897) - - - h5diff added a command line option to ignore attributes. - - h5diff would ignore all objects with a supplied path if the exclude-path argument is used. - Adding the exclude-attribute argument will only exclude attributes, with the supplied path, - from comparison. - - (ADB - 2020/07/20, HDFFV-5935) - - - h5diff added another level to the verbose argument to print filenames. - - Added verbose level 3 that is level 2 plus the filenames. The levels are: - 0 : Identical to '-v' or '--verbose' - 1 : All level 0 information plus one-line attribute status summary - 2 : All level 1 information plus extended attribute status report - 3 : All level 2 information plus file names - - (ADB - 2020/07/20, HDFFV-1005) - - - h5repack was fixed to repack the reference attributes properly. - - The code line that checks if the update of reference inside a compound - datatype is misplaced outside the code block loop that carries out the - check. In consequence, the next attribute that is not the reference - type was repacked again as the reference type and caused the failure of - repacking. The fix is to move the corresponding code line to the correct - code block. - - (KY -2020/02/10, HDFFV-11014) - - - h5diff was updated to use the new reference APIs. - - h5diff uses the new reference APIs to compare references. - Attribute references can also be compared. - - (ADB - 2019/12/19, HDFFV-10980) - - - h5dump and h5ls were updated to use the new reference APIs. - - The tools library now use the new reference APIs to inspect a - file. Also the DDL spec was updated to reflect the format - changes produced with the new APIs. The export API and support - functions in the JNI were updated to match. - - (ADB - 2019/12/06, HDFFV-10876 and HDFFV-10877) + - Performance @@ -1429,18 +266,12 @@ Bug Fixes since HDF5-1.12.0 release Fortran API ----------- - - Corrected INTERFACE INTENT(IN) to INTENT(OUT) for buf_size in h5fget_file_image_f. - - (MSB - 2020/02/18, HDFFV-11029) + - High-Level Library ------------------ - - Fixed HL_test_packet, test for packet table vlen of vlen. - - Incorrect length assignment. - - (ADB - 2021/10/14) + - Fortran High-Level APIs @@ -1460,23 +291,7 @@ Bug Fixes since HDF5-1.12.0 release C++ APIs -------- - - Added DataSet::operator= - - Some compilers complain if the copy constructor is given explicitly - but the assignment operator is implicitly set to default. - - (2021/05/19) - - - Testing - ------- - - Stopped java/test/junit.sh.in installing libs for testing under ${prefix} - - Lib files needed are now copied to a subdirectory in the java/test - directory, and on Macs the loader path for libhdf5.xxxs.so is changed - in the temporary copy of libhdf5_java.dylib. - - (LRK, 2020/07/02, HDFFV-11063) + - Platforms Tested diff --git a/release_docs/USING_CMake_Examples.txt b/release_docs/USING_CMake_Examples.txt index a12a952..920705b 100644 --- a/release_docs/USING_CMake_Examples.txt +++ b/release_docs/USING_CMake_Examples.txt @@ -20,15 +20,14 @@ Notes: This short instruction is written for users who want to quickly I.
