The scripts can be used to build HDF5 C and C++ + applications (i.e, similar to the compiler scripts produced by the Autotools builds). + + (ADB - 2018/03/08, HDFFV-4359) + + - Refactored use of CMAKE_BUILD_TYPE for new variable, which understands + the type of generator in use. + + Added new configuration macros to use new HDF_BUILD_TYPE variable. This + variable is set correctly for the type of generator being used for the build. + + (ADB - 2018/01/08, HDFFV-10385, HDFFV-10296) + + - Autotools builds + ------------------ + + - Removed version-specific gcc/gfortran flags for version 4.0 (inclusive) + and earlier. + + The config/gnu-flags file, which is sourced as a part of the configure + process, adds version-specific flags for use when building HDF5. Most of + these flags control warnings and do not affect the final product. + + Flags for older versions of the compiler were consolidated into the + common flags section. Moving these flags simplifies maintenance of + the file. + + The upshot of this is that building with ancient versions of gcc + (<= 4.0) will possibly no longer work without hand-hacking the file + to remove the flags not understood by that version of the compiler. + Nothing should change when building with gcc >= 4.1. + + (DER - 2017/05/31, HDFFV-9937) + + - -fno-omit-frame-pointer was added when building with debugging symbols + enabled. + + Debugging symbols can be enabled independently of the overall build + mode in both the autotools and CMake. This allows (limited) debugging + of optimized code. Since many debuggers rely on the frame pointer, + we've disabled this optimization when debugging symbols are requested + (e.g.: via building with --enable-symbols). + + (DER - 2017/05/31, HDFFV-10226) + + + Library: + -------- + - Added an enumerated value to H5F_libver_t for H5Pset_libver_bounds(). + + Currently, the library defines two values for H5F_libver_t and supports + only two pairs of (low, high) combinations as derived from these values. + Thus the bounds setting via H5Pset_libver_bounds() is rather restricted. + + Added an enumerated value (H5F_LIBVER_V18) to H5F_libver_t and + H5Pset_libver_bounds() now supports five pairs of (low, high) combinations + as derived from these values. This addition provides the user more + flexibility in setting bounds for object creation. + + (VC - 2018/03/14) + + - Added prefix option to VDS files. + + Currently, VDS source files must be in the active directory to be + found by the virtual file. Adding the option of a prefix to be set + on the virtual file, using a data access property list (DAPL), + allows the source files to locate at an absolute or relative path + to the virtual file. + Private utility functions in H5D and H5L packages merged into single + function in H5F package. + + New public APIs: + herr_t H5Pset_virtual_prefix(hid_t dapl_id, const char* prefix); + ssize_t H5Pget_virtual_prefix(hid_t dapl_id, char* prefix /*out*/, size_t size); + The prefix can also be set with an environment variable, HDF5_VDS_PREFIX. + + (ADB - 2017/12/12, HDFFV-9724, HDFFV-10361) + + - H5FDdriver_query() API call added to the C library. + + This new library call allows the user to query a virtual file driver + (VFD) for the feature flags it supports (listed in H5FDpublic.h). + This can be useful to determine if a VFD supports SWMR, for example. + + Note that some VFDs have feature flags that may only be present + after a file has been created or opened (e.g.: the core VFD will + have the H5FD_FEAT_POSIX_COMPAT_HANDLE flag set if the backing + store is switched on). Since the new API call queries a generic VFD + unassociated with a file, these flags will never be returned. + + (DER - 2017/05/31, HDFFV-10215) + + - H5FD_FEAT_DEFAULT_VFD_COMPATIBLE VFD feature flag added to the C library. + + This new feature flag indicates that the VFD is compatible with the + default VFD. VFDs that set this flag create single files that follow + the canonical HDF5 file format. + + (DER - 2017/05/31, HDFFV-10214) + + - The H5I_REFERENCE value in the H5I_type_t enum (defined in H5Ipublic.h) + has been marked as deprecated. + + This ID type value is not used in the C library. i.e.: There are no + hid_t values that are of ID type H5I_REFERENCE. + + This enum value will be removed in a future major version of the library. + The code will remain unchanged in the HDF5 1.10.x releases and branches. + + (DER - 2017/04/05, HDFFV-10252) + + + Parallel Library: + ----------------- + - Enabled compression for parallel applications. + + With this release parallel applications can create and write compressed + datasets (or the datasets with the filters such as Fletcher32 applied). + + (EIP - 2018/03/29) + + - Addressed slow file close on some Lustre file systems. + + Slow file close has been reported on some Lustre file systems. + While the ultimate cause is not understood fully, the proximate + cause appears to be long delays in MPI_File_set_size() calls at + file close and flush. + + To minimize this problem pending a definitive diagnosis and fix, + PHDF5 has been modified to avoid MPI_File_set_size() calls when + possible. This is done by comparing the library's EOA (End of + Allocation) with the file systems EOF, and skipping the + MPI_File_set_size() call if the two match. + + (JRM - 2018/03/29) + + - Optimized parallel open/location of the HDF5 super-block. + + Previous releases of PHDF5 required all parallel ranks to + search for the HDF5 superblock signature when opening the + file. As this is accomplished more or less as a synchronous + operation, a large number of processes can experience a + slowdown in the file open due to filesystem contention. + + As a first step in improving the startup/file-open performance, + we allow MPI rank 0 of the associated MPI communicator to locate + the base offset of the super-block and then broadcast that result + to the remaining ranks in the parallel group. Note that this + approach is utilized ONLY during file opens which employ the MPIO + file driver in HDF5 by previously having called H5Pset_fapl_mpio(). + + HDF5 parallel file operations which do not employ multiple ranks + e.g. specifiying MPI_COMM_SELF (whose MPI_Comm_size == 1) + as opposed to MPI_COMM_WORLD, will not be affected by this + optimization. Conversely, parallel file operations on subgroups + of MPI_COMM_WORLD are allowed to be run in parallel with each + subgroup operating as an independant collection of processes. + + (RAW - 2017/10/10, HDFFV-10294) + + - Added large (>2GB) MPI-IO transfers. + + Previous releases of PHDF5 would fail when attempting to + read or write greater than 2GB of data in a single IO operation. + This issue stems principally from an MPI API whose definitions + utilize 32 bit integers to describe the number of data elements + and datatype that MPI should use to effect a data transfer. + Historically, HDF5 has invoked MPI-IO with the number of + elements in a contiguous buffer represented as the length + of that buffer in bytes. + + Resolving the issue and thus enabling larger MPI-IO transfers + is accomplished first, by detecting when a user IO request would + exceed the 2GB limit as described above. Once a transfer request + is identified as requiring special handling, PHDF5 now creates a + derived datatype consisting of a vector of fixed sized blocks + which is in turn wrapped within a single MPI_Type_struct to + contain the vector and any remaining data. The newly created + datatype is then used in place of MPI_BYTE and can be used to + fulfill the original user request without encountering API + errors. + + (RAW - 2017/09/10, HDFFV-8839) + + + C++ Library: + ------------ + - The following C++ API wrappers have been added to the C++ Library: + + H5Lcreate_soft: + // Creates a soft link from link_name to target_name. + void link(const char *target_name, const char *link_name,...) + void link(const H5std_string& target_name,...) + + + H5Lcreate_hard: + // Creates a hard link from new_name to curr_name. + void link(const char *curr_name, const Group& new_loc,...) + void link(const H5std_string& curr_name, const Group& new_loc,...) + + // Creates a hard link from new_name to curr_name in same location. + void link(const char *curr_name, const hid_t same_loc,...) + void link(const H5std_string& curr_name, const hid_t same_loc,...) + + Note: previous version of H5Location::link will be deprecated. + + + H5Lcopy: + // Copy an object from a group of file to another. + void copyLink(const char *src_name, const Group& dst,...) + void copyLink(const H5std_string& src_name, const Group& dst,...) + + // Copy an object from a group of file to the same location. + void copyLink(const char *src_name, const char *dst_name,...) + void copyLink(const H5std_string& src_name,...) + + + H5Lmove: + // Rename an object in a group or file to a new location. + void moveLink(const char* src_name, const Group& dst,...) + void moveLink(const H5std_string& src_name, const Group& dst,...) + + // Rename an object in a group or file to the same location. + void moveLink(const char* src_name, const char* dst_name,...) + void moveLink(const H5std_string& src_name,...) + + Note: previous version H5Location::move will be deprecated. + + + H5Ldelete: + // Removes the specified link from this location. + void unlink(const char *link_name, + const LinkAccPropList& lapl = LinkAccPropList::DEFAULT) + void unlink(const H5std_string& link_name, + const LinkAccPropList& lapl = LinkAccPropList::DEFAULT) + + Note: additional parameter is added to previous H5Location::unlink. + + + H5Tencode and H5Tdecode: + // Creates a binary object description of this datatype. + void DataType::encode() - C API H5Tencode() + + // Returns the decoded type from the binary object description. + DataType::decode() - C API H5Tdecode() + ArrayType::decode() - C API H5Tdecode() + CompType::decode() - C API H5Tdecode() + DataType::decode() - C API H5Tdecode() + EnumType::decode() - C API H5Tdecode() + FloatType::decode() - C API H5Tdecode() + IntType::decode() - C API H5Tdecode() + StrType::decode() - C API H5Tdecode() + VarLenType::decode() - C API H5Tdecode() + + + H5Lget_info: + // Returns the information of the named link. + H5L_info_t getLinkInfo(const H5std_string& link_name,...) + + (BMR - 2018/03/11, HDFFV-10149) + + - Added class LinkCreatPropList for link create property list. + + (BMR - 2018/03/11, HDFFV-10149) + + - Added overloaded functions H5Location::createGroup to take a link + creation property list. + Group createGroup(const char* name, const LinkCreatPropList& lcpl) + Group createGroup(const H5std_string& name, const LinkCreatPropList& lcpl) + + (BMR - 2018/03/11, HDFFV-10149) + + - A document is added to the HDF5 C++ API Reference Manual to show the + mapping from a C API to C++ wrappers. It can be found from the main + page of the C++ API Reference Manual. + + (BMR - 2017/10/17, HDFFV-10151) + + + Java Library: + ---------------- + - Wrapper added for enabling the error stack. + + H5error_off would disable the error stack reporting. In order + to re-enable the reporting, the error stack info needs to be + saved so that H5error_on can revert state. + + (ADB - 2018/03/13, HDFFV-10412) + + - Wrappers were added for the following C APIs: + H5Pset_evict_on_close + H5Pget_evict_on_close + H5Pset_chunk_opts + H5Pget_chunk_opts + H5Pset_efile_prefix + H5Pget_efile_prefix + H5Pset_virtual_prefix + H5Pget_virtual_prefix + + (ADB - 2017/12/20) + + - The H5I_REFERENCE value in the H5I_type_t enum (defined in H5Ipublic.h) + has been marked as deprectated. + + JNI code which refers to this value will be removed in a future + major version of the library. The code will remain unchanged in the + 1.10.x releases and branches. + + See the C library section, above, for further information. + + (HDFFV-10252, DER, 2017/04/05) + + + Tools: + ------ + - h5diff has a new option to display error stack. + + Updated h5diff with the --enable-error-stack argument, which + enables the display of the hdf5 error stack. This completes the + improvement to the main tools: h5copy, h5diff, h5dump, h5ls and + h5repack. + + (ADB - 2017/08/30, HDFFV-9774) + + +Support for new platforms, languages and compilers. +======================================= + - None + +Bug Fixes since HDF5-1.10.1 release +================================== + + Library + ------- + - The data read after a direct chunk write to a chunked dataset with + one chunk was incorrect. + + The problem was due to the passing of a null dataset pointer to + the insert callback for the chunk index in the routine + H5D__chunk_direct_write() in H5Dchunk.c + The dataset was a single-chunked dataset which will use the + single chunk index when latest format was enabled on file creation. + The single chunk index was the only index that used this pointer + in the insert callback. + + Passed the dataset pointer to the insert callback for the chunk + index in H5D__chunk_direct_write(). + + (VC - 2018/03/20, HDFFV-10425) + + - Added public routine H5DOread_chunk to the high-level C library. + + The patch for H5DOwrite_chunk() to write an entire chunk to the file + directly was contributed by GE Healthcare and integrated by The HDF Group + developers. + + (VC - 2017/05/19, HDFFV-9934) + + - Freeing of object header after failed checksum verification. + + It was discovered that the object header (in H5Ocache.c) was not released properly + when the checksum verification failed and a re-load of the object + header was needed. + + Freed the object header that failed the chksum verification only + after the new object header is reloaded, deserialized and set up. + + (VC - 2018/03/14, HDFFV-10209) + + - Updated H5Pset_evict_on_close in H5Pfapl.c + + Changed the minor error number from H5E_CANTSET to H5E_UNSUPPORTED for + parallel library. + + (ADB - 2018/03/06, HDFFV-10414) + + - Fixed the problems with the utility function that could not handle lowercase + Windows drive letters. + + Added call to upper function for drive letter. + + (ADB - 2017/12/18, HDFFV-10307) + + - Fixed H5Sencode() bug when the number of elements selected was > 2^32. + + H5Sencode() incorrectly encodes dataspace selection with number of + elements exceeding 2^32. When decoding such selection via H5Sdecode(), + the number of elements in the decoded dataspace is not the same as + what is encoded. This problem exists for H5S_SEL_HYPER and + H5S_SEL_POINTS encoding. + + The cause of the problem is due to the fact that the library uses 32 bits to + encode counts and block offsets for the selection. + The solution is to use the original 32 bit encodings if possible, + but use a different way to encode selection if more that 32 bits is needed. + See details in the RFC: H5Sencode/H5Sdecode Format Change i + https://bitbucket.hdfgroup.org/projects/HDFFV/repos/hdf5doc/browse/RFCs/HDF5_Library/H5SencodeFormatChange. + + (VC - 2017/11/28, HDFFV-9947) + + - Fixed filter plugin handling in H5PL.c and H5Z.c to not require i availability of + dependent libraries (e.g., szip or zlib). + + It was discovered that the dynamic loading process used by + filter plugins had issues with library dependencies. + + CMake build process changed to use LINK INTERFACE keywords, which + allowed HDF5 C library to make dependent libraries private. The + filter plugin libraries no longer require dependent libraries + (such as szip or zlib) to be available. + + (ADB - 2017/11/16, HDFFV-10328) + + - Fixed rare object header corruption bug. + + In certain cases, such as when converting large attributes to dense + storage, an error could occur which would either fail an assertion or + cause file corruption. Fixed and added test. + + (NAF - 2017/11/14, HDFFV-10274) + + - Updated H5Zfilter_avail in H5Z.c. + + The public function checked for plugins, while the private + function did not. + + Modified H5Zfilter_avail and private function, H5Z_filter_avail. + Moved check for plugin from public to private function. Updated + H5P__set_filter due to change in H5Z_filter_avail. Updated tests. + + (ADB - 2017/10/10, HDFFV-10297, HDFFV-10319) + + - h5dump produced SEGFAULT when dumping corrypted file. + + The behavior was due to the error in the internal function H5HL_offset_into(). + + (1) Fixed H5HL_offset_into() to return error when offset exceeds heap data + block size. + (2) Fixed other places in the library that call this routine to detect + error routine. + + (VC - 2017/08/30, HDFFV-10216) + + - Fixes for paged aggregation feature. + + Skip test in test/fheap.c when: + (1) multi/split drivers and + (2) persisting free-space or using paged aggregation strategy + + (VC, 2017/07/10) + + Changes made based on RFC review comments: + (1) Added maximum value for file space page size + (2) Dropped check for page end metadata threshold + (3) Removed "can_shrink" and "shrink" callbacks for small section class + + (VC - 2017/06/09) + + - Fixed for infinite loop in H5VM_power2up(). + + The function H5VM_power2up() returns the next power of 2 + for n. When n exceeds 2^63, it overflows and becomes 0 causing + the infinite looping. + + The fix ensures that the function checks for n >= 2^63 + and returns 0. + + (VC - 2017/07/10, HDFFV-10217) + + - Fixed for H5Ocopy doesn't work with open identifiers. + + Changes made so that raw data for dataset objects are copied from + cached info when possible instead of flushing objects to file and + read them back in again. + + (VC - 2017/07/05, HDFFV-7853) + + - An uninitialized struct could cause a memory access error when using + variable-length or reference types in a compressed, chunked dataset. + + A struct containing a callback function pointer and a pointer to some + associated data was used before initialization. This could cause a + memory access error and system crash. This could only occur under + unusual conditions when using variable-lenth and reference types in + a compressed, chunked dataset. + + On recent versions of Visual Studio, when built in debug mode, the + debug heap will complain and cause a crash if the code in question + is executed (this will cause the objcopy test to fail). + + (DER - 2017/11/21, HDFFV-10330) + + - Fixed collective metadata writes on file close. + + It was discovered that metadata was being written twice as part of + the parallel file close behavior, once independently and once + collectively. + + A fix for this error was included as part of the parallel compression + feature but remained undocumented here. + + (RAW - 2017/12/01, HDFFV-10272) + + - If an HDF5 file contains a filter pipeline message with a 'number of + filters' field that exceeds the maximum number of allowed filters, + the error handling code will attempt to dereference a NULL pointer. + + This issue was reported to The HDF Group as issue #CVE-2017-17505. + https://security-tracker.debian.org/tracker/CVE-2017-17505 + https://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2017-17505 + + 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. + + This problem arose because the error handling code assumed that + the 'number of filters' field implied that a dynamic array of that + size had already been created and that the cleanup code should + iterate over that array and clean up each element's resources. If + an error occurred before the array has been allocated, this will + not be true. + + This has been changed so that the number of filters is set to + zero on errors. Additionally, the filter array traversal in the + error handling code now requires that the filter array not be NULL. + + (DER - 2018/02/06, HDFFV-10354) + + - If an HDF5 file contains a filter pipeline message which contains + a 'number of filters' field that exceeds the actual number of + filters in the message, the HDF5 C library will read off the end of + the read buffer. + + This issue was reported to The HDF Group as issue #CVE-2017-17506. + https://security-tracker.debian.org/tracker/CVE-2017-17506 + https://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2017-17506 + + NOTE: The HDF5 C library cannot produce such a file.

Also, + some changes support better cross-platform support. + + (ADB - 2018/02/01, HDFFV-10398) + + - Corrected usage of CMAKE_BUILD_TYPE variable. + + The use of the CMAKE_BUILD_TYPE is incorrect for multi-config + generators (Visual Studio and XCode) and is optional for single + config generators. Created a new macro to check + GLOBAL PROPERTY -> GENERATOR_IS_MULTI_CONFIG + Created two new HDF variable, HDF_BUILD_TYPE and HDF_CFG_BUILD_TYPE. + Defaults for these variables is "Release". + + (ADB - 2018/01/10, HDFFV-10385) + + - Added replacement of fortran flags if using static CRT. + + Added TARGET_STATIC_CRT_FLAGS call to HDFUseFortran.cmake file in + config/cmake_ext_mod folder. + + (ADB - 2018/01/08, HDFFV-10334) + + + - The hdf5 library used shared szip and zlib, which needlessly required + applications to link with the same szip and zlib libraries. + + Changed the target_link_libraries commands to use the static libs. + Removed improper link duplication of szip and zlib. + Adjusted the link dependencies and the link interface values of + the target_link_libraries commands. + + (ADB - 2017/11/14, HDFFV-10329) + + - CMake MPI + + CMake implementation for MPI was problematic and would create incorrect + MPI library references in the hdf5 libraries. + + Reworked the CMake MPI code to properly create CMake targets. Also merged + the latest CMake FindMPI.cmake changes to the local copy. This is necessary + until HDF changes the CMake minimum to 3.9 or greater. + + (ADB - 2017/11/02, HDFFV-10321) + + - Corrected FORTRAN_HAVE_C_LONG_DOUBLE processing in the autotools. + + A bug in the autotools Fortran processing code always set the + FORTRAN_HAVE_C_LONG_DOUBLE variable to be true regardless of + whether or not a C long double type was present. + + This would cause compilation failures on platforms where a C + long double type was not available and the Fortran wrappers + were being built. + + (DER - 2017/07/05, HDFFV-10247) + + - The deprecated --enable-production and --enable-debug configure options + failed to emit errors when passed an empty string + (e.g.: --enable-debug=""). + + Due to the way we checked for these options being set, it was possible + to avoid the error message and continue configuration if an empty string + was passed to the option. + + Any use of --enable-production or --enable-debug will now halt the + configuration step and emit a helpful error message + (use --enable-build-mode=debug|production instead). + + (DER - 2017/07/05, HDFFV-10248) + + - CMake + + Too many commands for POST_BUILD step caused command line to be + too big on windows. + + Changed foreach of copy command to use a custom command with the + use of the HDFTEST_COPY_FILE macro. + + (ADB - 2017/07/12, HDFFV-10254) + + - CMake test execution environment + + The parallel HDF5 test: 't_pread' assumed the use of autotools + and the directory structure associated with that testing approach. + Modified the test code to check whether the 'h5jam' utility can be + found in the same directory as the test executable (which is + preferred directory structure utilized by cmake) and if found + will invoke the tool directly rather than utilizing a relative path. + + (RAW - 2017/11/03, HDFFV-10318) + + - Fortran compilation fails for xlf and CMake builds. + + Fixed CMake shared library build for H5match_types and modules + + (MSB - 2017/12/19, HDFFV-10363) + + - Shared libraries fail test on OSX with Fortran enabled with CMake. + + Fixed by removing the F77 use of EQUIVALENCE and COMMON, replaced + using MODULES. Updated CMake. + + (MSB - 2017/12/07, HDFFV-10223) + + - The bin/trace script now emits an error code on problems and autogen.sh + will fail if bin/trace fails. + + The bin/trace script adds tracing functionality to public HDF5 API calls. + It is only of interest to developers who modify the HDF5 source code. + Previously, bin/trace just wrote an error message to stdout when it + encountered problems, so autogen.sh processing did not halt and a broken + version of the library could be built. The script will now return an + error code when it encounters problems, and autogen.sh will fail. + + This only affects users who run autogen.sh to rebuild the Autotools files, + which is not necessary to build HDF5 from source in official releases of the + library. CMake users are unaffected as bin/trace is not run via CMake + at this time. + + (DER - 2017/04/25, HDFFV-10178) + + - FC_BASENAME was changed from gfortran40 to gfortran in a few places. + + In the autotools, FC_BASENAME was set to gfortran40 in a few locations + (config/gnu-fflags and config/freebsd). This was probably a historical + artifact and did not seem to affect many users. + + The value is now correctly set to gfortran. + + (DER - 2017/05/26, HDFFV-10249) + + - The ar flags were changed to -cr (was: -cru) + + The autotools set the flags for ar to -cru by default. The -u flag, + which allows selective replacement of only the members which have + changed, raises warnings on some platforms, so the flags are now set to + -cr via AR_FLAGS in configure.ac. This causes the static library to + always be completely recreated from the object files on each build. + + (DER - 2017/11/15, HDFFV-10428) + + + Fortran + -------- + - Fixed compilation errors when using Intel 18 Fortran compilers + (MSB - 2017/11/3, HDFFV-10322) + + Tools + ----- + - h5clear + + An enhancement to the tool in setting a file's stored EOA. + + It was discovered that a crashed file's stored EOA in the superblock + was smaller than the actual file's EOF. When the file was reopened + and closed, the library truncated the file to the stored EOA. + + Added an option to the tool in setting the file's stored EOA in the + superblock to the maximum of (EOA, EOF) + increment. + An option was also added to print the file's EOA and EOF. + + (VC - 2018/03/14, HDFFV-10360) + + - h5repack + + h5repack changes the chunk parameters when a change of layout is not + specified and a filter is applied. + + HDFFV-10297, HDFFV-10319 reworked code for h5repack and h5diff code + in the tools library. The check for an existing layout was incorrectly + placed into an if block and not executed. The check was moved into + the normal path of the function. + + (ADB - 2018/02/21, HDFFV-10412) + + - h5dump + + The tools library will hide the error stack during file open. + + While this is preferable almost always, there are reasons to enable + display of the error stack when a tool will not open a file. Adding an + optional argument to the --enable-error-stack will provide this use case. + As an optional argument it will not affect the operation of the + --enable-error-stack. h5dump is the only tool to implement this change. + + (ADB - 2018/02/15, HDFFV-10384) + + - h5dump + + h5dump would output an indented blank line in the filters section. + + h5dump overused the h5tools_simple_prefix function, which is a + function intended to account for the data index (x,y,z) option. + Removed the function call for header information. + + (ADB - 2018/01/25, HDFFV-10396) + + - h5repack + + h5repack incorrectly searched internal object table for name. + + h5repack would search the table of objects for a name, if the + name did not match it tried to determine if the name without a + leading slash would match. The logic was flawed! The table + stored names(paths) without a leading slash and did a strstr + of the table path to the name. + The assumption was that if there was a difference of one then + it was a match, however "pressure" would match "/pressure" as + well as "/pressure1", "/pressure2", etc. Changed logic to remove + any leading slash and then do a full compare of the name. + + (ADB - 2018/01/18, HDFFV-10393) + + - h5repack + + h5repack failed to handle command line parameters for customer filters. + + User defined filter parameter conversions would fail when integers were + represented on the command line with character string + larger then 9 characters. Increased local variable array for storing + the current command line parameter to prevent buffer overflows. + + (ADB - 2018/01/17, HDFFV-10392) + + - h5diff + + h5diff seg faulted if comparing VL strings against fixed strings. + + Reworked solution for HDFFV-8625 and HDFFV-8639. Implemented the check + for string objects of same type in the diff_can_type function by + adding an if(tclass1 == H5T_STRING) block. This "if block" moves the + same check that was added for attributes to this function, which is + used by all object types. This function handles complex type structures. + Also added a new test file in h5diffgenttest for testing this issue + and removed the temporary files used in the test scripts. + + (ADB - 2018/01/04, HDFFV-8745) + + - h5repack + + h5repack failed to copy a dataset with existing filter. + + Reworked code for h5repack and h5diff code in the tools library. Added + improved error handling, cleanup of resources and checks of calls. + Modified H5Zfilter_avail and private function, H5Z_filter_avail. + Moved check for plugin from public to private function. Updated + H5P__set_filter due to change in H5Z_filter_avail. Updated tests. + Note, h5repack output display has changed to clarify the individual + steps of the repack process. The output indicates if an operation + applies to all objects. Lines with notation and no information + have been removed. + + (ADB - 2017/10/10, HDFFV-10297, HDFFV-10319) + + - h5repack + + h5repack always set the User Defined filter flag to H5Z_FLAG_MANDATORY. + + Added another parameter to the 'UD=' option to set the flag by default + to '0' or H5Z_FLAG_MANDATORY, the other choice is '1' or H5Z_FLAG_OPTIONAL. + + (ADB - 2017/08/31, HDFFV-10269) + + - h5ls + + h5ls generated error on stack when it encountered a H5S_NULL + dataspace. + + Adding checks for H5S_NULL before calling H5Sis_simple (located + in the h5tools_dump_mem function) fixed the issue. + + (ADB - 2017/08/17, HDFFV-10188) + + - h5repack + + Added tests to h5repack.sh.in to verify options added for paged + aggregation work as expected. + + (VC - 2017/08/03) + + - h5dump + + h5dump segfaulted on output of XML file. + + Function that escape'd strings used the full buffer length + instead of just the length of the replacement string in a + strncpy call. Using the correct length fixed the issue. + + (ADB - 2017/08/01, HDFFV-10256) + + - h5diff + + h5diff segfaulted on compare of a NULL variable length string. + + Improved h5diff compare of strings by adding a check for + NULL strings and setting the lengths to zero. + + (ADB - 2017/07/25, HDFFV-10246) + + - h5import + + h5import crashed trying to import data from a subset of a dataset. + + Improved h5import by adding the SUBSET keyword. h5import understands + to use the Count times the Block as the size of the dimensions. + Added INPUT_B_ORDER keyword to old-style configuration files. + The import from h5dump function expects the binary files to use native + types (FILE '-b' option) in the binary file. + + (ADB - 2017/06/15, HDFFV-10219) + + - h5repack + + h5repack did not maintain the creation order flag of the root + group. + + Improved h5repack by reading the creation order and applying the + flag to the new root group. Also added arguments to set the + order and index direction, which applies to the traversing of the + original file, on the command line. + + (ADB - 2017/05/26, HDFFV-8611) + + - h5diff + + h5diff failed to account for strpad type and null terminators + of char strings. Also, h5diff failed to account for string length + differences and would give a different result depending on file + order in the command line. + + Improved h5diff compare of strings and arrays by adding a check for + string lengths and if the strpad was null filled. + + (ADB - 2017/05/18, HDFFV-9055, HDFFV-10128) + + High-Level APIs: + ------ + - H5DOwrite_chunk() problems when overwriting an existing chunk with + no filters enabled. + + When overwriting chunks and no filters were being used, the library would + fail (when asserts are enabled, e.g. debug builds) or incorrectly + insert additional chunks instead of overwriting (when asserts are not + enabled, e.g. production builds). + + This has been fixed and a test was added to the hl/test_dset_opt test. + + (DER - 2017/05/11, HDFFV-10187) + + C++ APIs + -------- + - Removal of memory leaks. + + A private function was inadvertently called, causing memory leaks. This + is now fixed. + + (BMR - 2018/03/12 - User's reported in email) + + Testing + ------- + - Memory for three variables in testphdf5's coll_write_test was malloced + but not freed, leaking memory when running the test. + + The variables' memory is now freed. + + (LRK - 2018/03/12, HDFFV-10397) + + - Refactored the testpar/t_bigio.c test to include ALARM macros + + Changed the test to include the ALARM_ON and ALARM_OFF macros which + are intended to prevent nightly test hangs that have been observed + with this particular parallel test example. The code was also modified to + simplify status reporting (only from MPI rank 0) and additional + status checking added. + + (RAW - 2017/11/08, HDFFV-10301) + + +Supported Platforms +=================== + + Linux 2.6.32-696.16.1.el6.ppc64 gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-18) + #1 SMP ppc64 GNU/Linux g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-18) + (ostrich) GNU Fortran (GCC) 4.4.7 20120313 (Red Hat 4.4.7-18) + IBM XL C/C++ V13.1 + IBM XL Fortran V15.1 + + Linux 3.10.0-327.10.1.el7 GNU C (gcc), Fortran (gfortran), C++ (g++) + #1 SMP x86_64 GNU/Linux compilers: + (kituo/moohan) Version 4.8.5 20150623 (Red Hat 4.8.5-4) + Version 4.9.3, Version 5.2.0, + Intel(R) C (icc), C++ (icpc), Fortran (icc) + compilers: + Version 17.0.0.098 Build 20160721 + MPICH 3.1.4 compiled with GCC 4.9.3 + + SunOS 5.11 32- and 64-bit Sun C 5.12 SunOS_sparc + (emu) Sun Fortran 95 8.6 SunOS_sparc + Sun C++ 5.12 SunOS_sparc + + Windows 7 Visual Studio 2012 w/ Intel Fortran 15 (cmake) + Visual Studio 2013 w/ Intel Fortran 15 (cmake) + Visual Studio 2015 w/ Intel Fortran 16 (cmake) + + Windows 7 x64 Visual Studio 2012 w/ Intel Fortran 15 (cmake) + Visual Studio 2013 w/ Intel Fortran 15 (cmake) + Visual Studio 2015 w/ Intel Fortran 16 (cmake) + Visual Studio 2015 w/ Intel C, Fortran 2017 (cmake) + Visual Studio 2015 w/ MSMPI 8 (cmake) + Cygwin(CYGWIN_NT-6.1 2.8.0(0.309/5/3) + gcc and gfortran compilers (GCC 5.4.0) + (cmake and autotools) + + Windows 10 Visual Studio 2015 w/ Intel Fortran 16 (cmake) + Cygwin(CYGWIN_NT-6.1 2.8.0(0.309/5/3) + gcc and gfortran compilers (GCC 5.4.0) + (cmake and autotools) + + Windows 10 x64 Visual Studio 2015 w/ Intel Fortran 16 (cmake) + + Mac OS X Yosemite 10.10.5 Apple clang/clang++ version 6.1 from Xcode 7.0 + 64-bit gfortran GNU Fortran (GCC) 4.9.2 + (osx1010dev/osx1010test) Intel icc/icpc/ifort version 15.0.3 + + Mac OS X El Capitan 10.11.6 Apple clang/clang++ version 7.3.0 from Xcode 7.3 + 64-bit gfortran GNU Fortran (GCC) 5.2.0 + (osx1011dev/osx1011test) Intel icc/icpc/ifort version 16.0.2 + + Mac OS Sierra 10.12.6 Apple LLVM version 8.1.0 (clang/clang++-802.0.42) + 64-bit gfortran GNU Fortran (GCC) 7.1.0 + (swallow/kite) Intel icc/icpc/ifort version 17.0.2 + + +Tested Configuration Features Summary +===================================== + + In the tables below + y = tested + n = not tested in this release + C = Cluster + W = Workstation + x = not working in this release + dna = does not apply + ( ) = footnote appears below second table + <blank> = testing incomplete on this feature or platform + +Platform C F90/ F90 C++ zlib SZIP + parallel F2003 parallel +Solaris2.11 32-bit n y/y n y y y +Solaris2.11 64-bit n y/n n y y y +Windows 7 y y/y n y y y +Windows 7 x64 y y/y y y y y +Windows 7 Cygwin n y/n n y y y +Windows 7 x64 Cygwin n y/n n y y y +Windows 10 y y/y n y y y +Windows 10 x64 y y/y n y y y +Mac OS X Mountain Lion 10.8.5 64-bit n y/y n y y y +Mac OS X Mavericks 10.9.5 64-bit n y/y n y y y +Mac OS X Yosemite 10.10.5 64-bit n y/y n y y y +Mac OS X El Capitan 10.11.6 64-bit n y/y n y y y +CentOS 7.2 Linux 2.6.32 x86_64 PGI n y/y n y y y +CentOS 7.2 Linux 2.6.32 x86_64 GNU y y/y y y y y +CentOS 7.2 Linux 2.6.32 x86_64 Intel n y/y n y y y +Linux 2.6.32-573.18.1.el6.ppc64 n y/y n y y y + + +Platform Shared Shared Shared Thread- + C libs F90 libs C++ libs safe +Solaris2.11 32-bit y y y y +Solaris2.11 64-bit y y y y +Windows 7 y y y y +Windows 7 x64 y y y y +Windows 7 Cygwin n n n y +Windows 7 x64 Cygwin n n n y +Windows 10 y y y y +Windows 10 x64 y y y y +Mac OS X Mountain Lion 10.8.5 64-bit y n y y +Mac OS X Mavericks 10.9.5 64-bit y n y y +Mac OS X Yosemite 10.10.5 64-bit y n y y +Mac OS X El Capitan 10.11.6 64-bit y n y y +CentOS 7.2 Linux 2.6.32 x86_64 PGI y y y n +CentOS 7.2 Linux 2.6.32 x86_64 GNU y y y y +CentOS 7.2 Linux 2.6.32 x86_64 Intel y y y n +Linux 2.6.32-573.18.1.el6.ppc64 y y y n + +Compiler versions for each platform are listed in the preceding +"Supported Platforms" table. + + +More Tested Platforms +===================== +The following platforms are not supported but have been tested for this release. + + Linux 2.6.32-573.22.1.el6 GNU C (gcc), Fortran (gfortran), C++ (g++) + #1 SMP x86_64 GNU/Linux compilers: + (mayll/platypus) Version 4.4.7 20120313 + Version 4.9.3, 5.3.0, 6.2.0 + PGI C, Fortran, C++ for 64-bit target on + x86-64;
