+
+New Features
+============
+
+ Configuration:
+ -------------
+ - Disable memory sanity checks in the Autotools in release branches
+
+ The library can be configured to use internal memory sanity checking,
+ which replaces C API calls like malloc(3) and free(3) with our own calls
+ which add things like heap canaries. These canaries can cause problems
+ when external filter plugins reallocate canary-marked buffers.
+
+ For this reason, the default will be to not use the memory allocation
+ sanity check feature in release branches (e.g., hdf5_1_10_7).
+ Debug builds in development branches (e.g., develop, hdf5_1_10) will
+ still use them by default.
+
+ This change only affects Autotools debug builds. Non-debug autotools
+ builds and all CMake builds do not enable this feature by default.
+
+ (DER - 2020/08/19)
+
+ - 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 overriden 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. A new option USE_LIBAEC is required
+ to compensate for the different files produced by AEC build.
+
+ Autotools does not build the compression libraries within hdf5 builds,
+ but will use an installed libaec when configured as before with the
+ option --with-libsz=<path to libaec directory>.
+
+ (ADB - 2020/04/22, OESS-65)
+
+ - CMake ConfigureChecks.cmake file now uses CHECK_STRUCT_HAS_MEMBER
+
+ Some handcrafted tests in HDFTests.c have 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)
+
+ - 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)
+
+
+ Library:
+ --------
+ - Add metadata cache optimization to reduce skip list usage
+
+ On file flush or close, the metadata cache attempts to write out
+ all dirty entries in increasing address order. To do this, it needs
+ an address sorted list of metadata entries. Further, since flushing
+ one metadata cache entry can dirty another, this list must support
+ efficient insertion and deletion.
+
+ The metadata cache uses a skip list of all dirty entries for this
+ purpose. Before this release, this skip list was maintained at all
+ times. However, since profiling indicates that this imposes a
+ significant cost, we now construct and maintain the skip list only
+ when needed. Specifically, we enable the skip list and load it with
+ a list of all dirty entries in the metadata cache just before a flush,
+ and disable it after the flush.
+
+ (JRM - 2020/08/17, HDFFV-11034)
+
+ - Add BEST_EFFORT value to HDF5_USE_FILE_LOCKING environment variable
+
+ This change adds a BEST_EFFORT to the TRUE/FALSE, 1/0 settings that
+ were previously accepted. This option turns on file locking but
+ ignores locking errors when the library detects that file locking
+ has been disabled on a file system (useful on some HPC Lustre
+ installations).
+
+ The capitalization of BEST_EFFORT is mandatory.
+
+ 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)
+
+
+ - Add H5Pset/get_file_locking() API calls
+
+ This change adds new API calls which can be used to set or get the
+ file locking parameters. The single API call sets both the "use file
+ locking" flag and the "ignore disabled file locking" flag.
+
+ When opening a file multiple times without closing, the file MUST be
+ opened with the same file locking settings. Opening a file with different
+ file locking settings will fail (this is similar to the behavior of
+ H5Pset_fclose_degree()).
+
+ 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)
+
+ - 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)
+
+ - Fixed an assertion failure in the parallel library when collectively
+ filling chunks. As it is required that chunks be written in
+ monotonically non-decreasing order of offset in the file, this assertion
+ was being triggered when the list of chunk file space allocations being
+ passed to the collective chunk filling routine was not sorted according
+ to this particular requirement.
+
+ The addition of a sort of the out of order chunks trades a bit of
+ performance for the elimination of this assertion and of any complaints
+ from MPI implementations about the file offsets used being out of order.
+
+ (JTH - 2019/10/07)
+
+ Fortran Library:
+ ----------------
+ - 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)
+
+ - Added new Fortran parameters:
+
+ H5F_LIBVER_ERROR_F
+ H5F_LIBVER_NBOUNDS_F
+ H5F_LIBVER_V18_F
+ H5F_LIBVER_V110_F
+
+ - Added new Fortran API: h5pget_libver_bounds_f
+
+ (MSB - 2020/02/11, HDFFV-11018)
+
+ 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:
+ ----------------
+ - 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)
+
+ Tools:
+ ------
+ - 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.

+
+Bug Fixes since HDF5-1.10.6 release
+==================================
+
+ Library
+ -------
+ - Fix bug and simplify collective metadata write operation when some ranks
+ have no entries to contribute. This fixes parallel regression test
+ failures with IBM SpectrumScale MPI on the Summit system at ORNL.
+
+ (QAK - 2020/09/02)
+
+ - Avoid setting up complex MPI types with 0-length vectors, which some
+ MPI implementations don't handle well. (In particular, IBM
+ SpectrumScale MPI on the Summit system at ORNL)
+
+ (QAK - 2020/08/21)
+
+ - Fixed use-of-uninitialized-value error
+
+ Appropriate initialization of local structs was added to remove the
+ use-of-uninitialized-value errors reported by MemorySanitizer.
+
+ (BMR - 2020/8/13, HDFFV-11101)
+
+ - 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.
+
+ A fix is applied to allow the creation of a dataset in such
+ situation, as specified in the user documentation.
+
+ (BMR - 2020/8/13, 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)
+
+ - 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 past 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 - 2020/7/31, HDFFV-11120 and HDFFV-11121)
+
+ - 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 asserts 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 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 issue CVE-2018-17438
+
+ A division by zero was discovered in H5D__select_io() of H5Dselect.c.
+ https://security-tracker.debian.org/tracker/CVE-2018-17438
+
+ A check was added to protect against division by zero. When such
+ situation occurs again, the normal HDF5 error handling will be invoked,
+ instead of segmentation fault.
+
+ (BMR, DER - 2020/07/09, HDFFV-10587)
+
+ - 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 - 2020/6/19, HDFFV-10591)
+
+ - Don't allocate an empty (0-dimensioned) chunked dataset's chunk
+ index, until the dataset's dimensions are increased.
+
+ (QAK - 2020/05/07)
+
+ Configuration
+ -------------
+ - Stopped addition of szip header and include directory path for
+ incompatible libsz
+
+ szlib.h is the same for both 32-bit and 64-bit szip, and the header file
+ and its path were added to the HDF5 binary even though the configure
+ check of a function in libsz later failed and szip compression was not
+ enabled. The header file and include path are now added only when the
+ libsz function passes the configure check.
+
+ (LRK - 2020/08/17, HDFFV-10830)
+
+ - Added -fsanitize=address autotools configure option for Clang compiler
+
+ Clang sanitizer options were also added for Clang compilers with CMake.
+
+ (LRK, 2020/08/05, HDFFV-10836)
+
+ - Updated testh5cc.sh.in for functions versioned in HDF5 1.10.
+
+ testh5cc.sh previously tested that the correct version of a function
+ versioned in HDF5 1.6 or 1.8 was compiled when one of
+ H5_NO_DEPRECATED_SYMBOLS or H5_USE_16_API_DEFAULT were defined. This
+ test was extended for additional testing with H5_USE_18_API_DEFAULT.
+
+ (LRK, 2020/06/22, HDFFV-11000)
+
+ - 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)
+
+ Performance
+ -------------
+ - None
+
+ Java Library:
+ ----------------
+ - None
+
+ Fortran
+ --------
+ - Corrected INTERFACE INTENT(IN) to INTENT(OUT) for buf_size in h5fget_file_image_f.
+
+ (MSB - 2020/2/18, HDFFV-11029)
+
+ - Fixed configure issue when building HDF5 with NAG Fortran 7.0.
+
+ HDF5 now accounts for the addition of half-precision floating-point
+ in NAG 7.0 with a KIND=16.
+
+ (MSB - 2020/02/28, HDFFV-11033)
+
+ Tools
+ -----
+ - 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 eclude attributes, with the supplied path,
+ from comparision.
+
+ (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-10005)
+
+ - 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)
+
+ High-Level APIs:
+ ------
+ - The H5DSis_scale function was updated to return "not a dimension scale" (0)
+ instead of failing (-1), when CLASS or DIMENSION_SCALE attributes are
+ not written according to Dimension Scales Specification.
+
+ (EIP - 2020/08/12, HDFFV-10436)

+
+ Lib files needed are now copied to a subdirectory in the java/test

+Known Problems
+==============
+ CMake files do not behave correctly with paths containing spaces.
+ Do not use spaces in paths because the required escaping for handling spaces
+ results in very complex and fragile build files.
+ 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.
+
+ Two tests fail attempting collective writes with OpenMPI 3.0.0/GCC-7.2.0-2.29:
+ testphdf5 (ecdsetw, selnone, cchunk1, cchunk3, cchunk4, and actualio)
+ t_shapesame (sscontig2)
+
+ 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.
+
+ 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
+the share folder.
+
+The bin folder contains the tools and the build scripts. Additionally, 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.
