(ADB - 2014/03/26) + + - When configuring a thread-safe HDF5 Library it is no longer necessary + to specify --enable-threadsafe with --with-pthreads if the Pthreads + library is in a standard location. (DER - 2014/04/11 HDFFV-8693) + + Library + ------- + - Added an H5free_memory API call. This should be used to free memory + that has been allocated by HDF5 API calls. H5Tget_member_name and + H5Pget_class_name are two examples. The main motivation for this call + is Windows, where it is common for application code and the HDF5 Library + to be using different C run-time libraries (CRT). Using the new call + ensures that the same CRT handles both the allocation and free. This + new function can also be useful in any case where the library uses a + different memory manager than the application, such as when a debug + memory manager is in use or when the HDF5 Library is wrapped for use + in a managed language like Python or Java. Fixes HDFFV-7710, 8519, + and 8851. (DER - 2014/04/11) + + - The Core VFD (aka Memory VFD) can now be configured to track dirty + regions in the file and only write out the changed regions on + flush/close. Additionally, a "page aggregation" size can be set that + will aggregate small writes into larger writes. For example, setting + a 1 MiB page aggregation size will logically partition the the + in-memory file into 1 MiB pages that will be written out in their + entirety if even a single byte is dirtied. The feature is controlled + via the new H5Pset/get_core_write_tracking() API call. A new + "core_paged" target has been added to the check-vfd target in + test/Makefile.am that exercises the feature over all HDF5 VFD-aware + tests. (DER - 2014/04/12) + + Parallel Library + ---------------- + - Removed MPI-POSIX VFD, as it wasn't helping anyone and was just + generating support questions. Application developers performing + parallel I/O should always use the MPI-IO VFD. + (QAK - 2014/03/28 HDFFV-8659) + + - Improved parallel I/O support to allow collective I/O on point + selections. (QAK - 2014/03/15) + + Tools + ----- + - None + + High-Level APIs + --------------- + - None + + Fortran API + ----------- + - Wrappers h5pset_file_image_f and h5pget_file_image_f were added to the + library.

(AKC - 2014/03/04 HDFFV-8694) + + +Bug Fixes since HDF5-1.8.12 +=========================== + + Configuration + ------------- + - CMake: When CMake commands are executed individually on the command line + and the external filters are being built, the CMAKE_BUILD_TYPE define + must be set to the same value as the configuration + (-DCMAKE_BUILD_TYPE:STRING=Release if using -C Release). This is needed + by the the szip and zlib filter build commands. (ADB - HDFFV-8695) + + - CMake: Removed use of the XLATE_UTILITY program. + (ADB - 2014/03/28 HDFFV-8640) + + - CMake: Added missing quotes in setting the CMAKE_EXE_LINKER_FLAGS for the + MPI option. (ADB - 2014/02/27 HDFFV-8674) + + - CMake: Configuration of the HDF5 C++ or Fortran libraries with the + thread-safety feature. + + C++ and/or Fortran + thread-safe is enforced as a non-supported + configuration. This matches the autotools. (DER - 2014/04/11) + + - CMake: Configuration of static HDF5 C library with the thread-safety + feature. + + Static + thread-safe + Win32 threads is not a supported configuration + due to the inability to automatically clean up thread-local storage. + This is expected to be fixed in a future release. In the meantime, a + work-around that uses internal functionality may allow the combination + to be used without resource leaks. Contact the help desk for more + information. (DER - 2014/04/11) + + - Autotools: Several changes were done to configure and installcheck. + + An export of LD_LIBRARY_PATH=<szip library location> was + removed from configure; make installcheck was revised to run + scripts installed in share/hdf5_examples to use the installed h5cc, etc. + to compile and run example source files also installed there. + + Make installcheck will now fail when a shared szip or other external lib + file cannot be found in the same manner that executables compiled and + linked with h5cc will fail to run when those lib files cannot be found + after install. Make installcheck should pass after setting + LD_LIBRARY_PATH to the szip location. (LRK - 2014/04/16) + + Library + ------- + - A Gnu Make directive (.NOTPARALLEL) is added to fortran/test/Makefile. + + AIX native make does not support this directive and would fail if + parallel make (e.g. make -j4) is used to build the library. AIX users + either do not use parallel make or install Gnu Make to build the library. + (AKC 2014/04/08 HDFFV-8738) + + - H5R.c: H5Rget_name gave an assertion failure if the "name" parameter + was NULL. + + Fixed H5Rget_name to return the size of the buffer needed to read a + name of the referenced object in this case. The size doesn't include + the NULL terminator. H5Rget_name returns negative on failure. + (MSB - 2014/01/22 HDFFV-8620) + + - H5Z.c: H5Zfilter_avail didn't check if a filter was available as a + dynamically loaded filter. The error manifested itself in the h5repack + tool when removing user-defined dynamically loaded filter. + + Added a code to find the filter among the dynamically loaded filters + after the function fails to find it among the registered filters. + (ADB - 2014/03/03 HDFFV-8629) + + - Memory leak: a memory leak was observed in conjunction to the + H5TS_errstk_key_g thread-local variable allocated in the H5E_get_stack + function in H5E.c. + + The shared HDF5 thread-safe library now no longer leaks thread-local + storage resources on Windows with Win32 threads. Currently, there is + no solution for this problem when HDF5 is statically built. We + disabled the build of the static HDF5 thread-safe library with + Win32 threads. (DER - 2014/04/11 HDFFV-8518) + + - H5Dio.c: Improved handling of NULL pointers to H5Dread/H5Dwrite + calls. Credit to Jason Newton (nevion@gmail.com) for the original patch. + + H5Dwrite/read failed when a NULL pointer was passed for a data buffer + and 0 elements were selected. Fixed. (QAK - 2014/04/16 HDFFV-8705) + + - Deprecated API (1_6 API): Improved handling of closing the library and + re-accessing it with a deprecated routine. + + When a program used a deprecated API (for example, H5Gcreate1), + closed the library, and reopened it again to access a group, dataset, + datatype, dataspace, attribute, or property list, HDF5 failed to + provide an identifier for the object. Fixed. + (NAF, QAK - 2014/04/16 HDFFV-8232) + + Parallel Library + ---------------- + - Fixed a missing H5F_Provisional module in HDF5mpio.f90 + (MSB - 2014/2/7 HDFFV-8651) + + Performance + ------------- + - None + + Tools + ----- + - The h5diff tool would report that a datafile compared with an exact + copy of the same datafile had differences. This was due to the issue + below of reading un-written chunks. This problem is also fixed. + (AKC - 2014/05/01 HDFFV-8637) + + - The h5dump and h5diff utilities occasionally produced different output + between Linux and Windows systems. This has been fixed. + + This happened to datasets that used chunked storage, with default fill + values, and some of the chunks had not been written. + When the dataset was read, the library failed to write the default fill + values to parts of the use buffer that were associated with the unwritten + chunks. (JP - 2014/05/01 HDFFV-8247) + + - The compress option is retired from bin/release. + (AKC - 2014/04/25 HDFFV-8755) + + - bin/release has a new option "zip" that produces a release zip file for + the Windows platform. (AKC - 2014/04/24 HDFFV-8433) + + - h5diff: Several failures relating to handling of strings attributes + are fixed. + + The tool crashed or gave an error message when one of the strings had + fixed size type and another variable-length size type. h5diff now flags such + strings as "not comparable". We plan to enhance the tool to handle + strings of the different types in the future releases. + (AKC - 2014/04/18 HDFFV-8625, 8639, 8745) + + - h5repack: h5repack would not remove user-defined filters. + Fixed by modifying h5repack to check if the filter is registered or + can be dynamically loaded. (ADB - 2014/03/03 HDFFV-8629) + + F90 API + ------- + - H5D_CHUNK_CACHE_NSLOTS_DFLT_F and H5D_CHUNK_CACHE_NBYTES_DFLT_F were + changed from the default KIND for INTEGER to INTEGER of KIND size_t. + (MSB - 2014/3/31 HDFFV-8689) + + C++ API + ------ + - Added throw() to all exception destructors. Credit to Jason Newton + (nevion@gmail.com) for the patch. (BMR - 2014/4/15 HDFFV-8623) + - Changed the default value for H5Location::getComment from 256 to 0 + to conform to C function and because it makes more sense. + (BMR - 2014/4/15) + + High-Level APIs: + ------ + - None + + Fortran High-Level APIs: + ------ + - None + + Testing + ------- + - testhdf5 now exits with EXIT_SUCCESS(0) if no errors, else + EXIT_FAILURE(1). (AKC - 2014/01/27 HDFFV-8572) + + - The big test now pays attention to the HDF5_DRIVER environment variable. + Previously, it would run all tests with the family, stdio, and sec2 + virtual file drivers (VFDs) for each VFD in the check-vfd make target, + regardless of the variable setting. It now checks the variable and + either runs the appropriate VFD-specific tests or skips as needed. + This saves much testing time. Fixes HDFFV-8554.

(ADB - 2014/04/14) + +* A Gnu Make directive (.NOTPARALLEL) is added to fortran/test/Makefile. + AIX native make does not support this directive and would fail if + parallel make (e.g. make -j4) is used to build the library. AIX users + either do not use parallel make or install Gnu Make to build the library. + (AKC 2014/04/08 HDFFV-8738) + +* CLANG compiler with the options -fcatch-undefined-behavior and -ftrapv + catches some undefined behavior in the alignment algorithm of the macro + DETECT_I in H5detect.c. Since the algorithm is trying to detect the alignment + of integers, ideally the flag -fcatch-undefined-behavior should not to be + used for H5detect.c. In the future, we can separate flags for H5detect.c + from the rest of the library. (SLU - 2013/10/16 HDFFV-8147) + +* Make provided by Solaris fails in "make check". Solaris users should use + gmake to build and install the HDF5 software. (AKC - 2013/10/08 - HDFFV-8534) + +* On OpenVMS, two soft conversion functions (H5T__conv_i_f and H5T__conv_f_i) + have bugs. They convert data between floating-point numbers and integers. + But the library's default is hard conversion. The user should avoid + explicitly enabling soft conversion between floating-point numbers and + integers. (Issue VMS-8; SLU - 2013/09/19) + +* On OpenVMS, ZLIB 1.2.8 library doesn't work properly. ZLIB 1.2.5 works + fine. So please use ZLIB 1.2.5 to build HDF5 library. (Issue VMS-5; + SLU 2013/09/19) + +* When building using the Cray compilers on Cray machines, HDF5 + configure mistakenly thinks the compiler is an intel compiler and + sets the -std=c99 flag which breaks configure on Cray. To build HDF5 + properly on a Cray machine, please consult with the instructions in + INSTALL_parallel for building on Hopper. + (MSC - 2013/04/26 - HDFFV-8429) + +* The 5.9 C++ compiler on Sun failed to compile a C++ test ttypes.cpp. It + complains with this message: + "/home/hdf5/src/H5Vprivate.h", line 130: Error: __func__ is not defined. + + The reason is that __func__ is a predefined identifier in C99 standard. The + HDF5 C library uses it in H5private.h. The test ttypes.cpp includes + H5private.h (H5Tpkg.h<-H5Fprivate.h<-H5Vprivate.h<-H5private.h). Sun's 5.9 + C++ compiler doesn't support __func__, thus fails to compile the C++ test. + But Sun's 5.11 C++ compiler does. To check whether your Sun C++ compiler + knows this identifier, try to compile the following simple C++ program: + #include<stdio.h> + + int main(void) + { + printf("%s\n", __func__); + return 0; + } + (SLU - 2012/11/5) + +* The C++ and FORTRAN bindings are not currently working on FreeBSD with the + native release 8.2 compilers (4.2.1), but are working with gcc 4.6 from the + ports (and probably gcc releases after that). + (QAK - 2012/10/19) + +* The following h5dump test case fails in BG/P machines (and potentially other + machines that use a command script to launch executables): + + h5dump --no-compact-subset -d "AHFINDERDIRECT::ah_centroid_t[0] it=0 tl=0" + tno-subset.h5 + + This is due to the embedded spaces in the dataset name being interpreted + by the command script launcher as meta-characters, thus passing three + arguments to h5dump's -d flag. The command passes if run by hand, just + not via the test script. + (AKC - 2012/05/03) + +* On hopper, the build failed when RUNSERIAL and RUNPARALLEL are set + to aprun -np X, because the H5lib_settings.c file was not generated + properly. Not setting those environment variables works, because + configure was able to automatically detect that it's a Cray system + and used the proper launch commands when necessary. + (MSC - 2012/04/18) + +* The data conversion test dt_arith.c fails in "long double" to integer + conversion on Ubuntu 11.10 (3.0.0.13 kernel) with GCC 4.6.1 if the library + is built with optimization -O3 or -O2. The older GCC (4.5) or newer kernal + (3.2.2 on Fedora) doesn't have the problem. Users should lower the + optimization level (-O1 or -O0) by defining CFLAGS in the command line of + "configure" like: + + CFLAGS=-O1 ./configure + + This will overwrite the library's default optimization level. + (SLU - 2012/02/07 - HDFFV-7829) + This issue is no longer present on Ubuntu 12.10 (3.5.0 kernel) with + gcc 4.7.2. + +* The STDIO VFD does not work on some architectures, possibly due to 32/64 + bit or large file issues. The basic STDIO VFD test is known to fail on + 64-bit SunOS 5.10 on SPARC when built with -m64 and 32-bit OS X/Darwin + 10.7.0. The STDIO VFD test has been disabled while we investigate and + a fix should appear in a future release. + (DER - 2011/10/14 - HDFFV-8235) + +* h5diff can report inconsistent results when comparing datasets of enum type + that contain invalid values. This is due to how enum types are handled in + the library and will be addressed in a future release. + (DER - 2011/10/14 - HDFFV-7527) + +* The links test can fail under the stdio VFD due to some issues with external + links. This will be investigated and fixed in a future release. + (DER - 2011/10/14 - HDFFV-7768) + +* After the shared library support was fixed for some bugs, it was discovered + that "make prefix=XXX install" no longer works for shared libraries. It + still works correctly for static libraries. Therefore, if you want to + install the HDF5 shared libraries in a location such as /usr/local/hdf5, + you need to specify the location via the --prefix option during configure + time. E.g, ./configure --prefix=/usr/local/hdf5 ... + (AKC - 2011/05/07 - HDFFV-7583) + +* The parallel test, t_shapesame, in testpar/, may run for a long time and may + be terminated by the alarm signal. If that happens, one can increase the + alarm seconds (default is 1200 seconds = 20 minutes) by setting the + environment variable, $HDF5_ALARM_SECONDS, to a larger value such as 3600 + (60 minutes). Note that the t_shapesame test may fail in some systems + (see the "While working on the 1.8.6 release..." problem below). If + it does, it will waste more time if $HDF5_ALARM_SECONDS is set + to a larger value. + (AKC - 2011/05/07) + +* The C++ and FORTRAN bindings are not currently working on FreeBSD. + (QAK - 2011/04/26) + +* Shared Fortran libraries are not quite working on AIX. While they are + generated when --enable-shared is specified, the fortran and hl/fortran + tests fail. We are looking into the issue. HL and C++ shared libraries + should now be working as intended, however. + (MAM - 2011/04/20) + +* The --with-mpe configure option does not work with Mpich2. + (AKC - 2011/03/10) + +* While working on the 1.8.6 release of HDF5, a bug was discovered that can + occur when reading from a dataset in parallel shortly after it has been + written to collectively. The issue was exposed by a new test in the parallel + HDF5 test suite, but had existed before that. We believe the problem lies with + certain MPI implementations and/or file systems. + + We have provided a pure MPI test program, as well as a standalone HDF5 + program, that can be used to determine if this is an issue on your system. + They should be run across multiple nodes with a varying number of processes. + These programs can be found at: + http://www.hdfgroup.org/ftp/HDF5/examples/known_problems/ + (NAF - 2011/01/19) + +* All the VFL drivers aren't backward compatible. In H5FDpublic.h, the + structure H5FD_class_t changed in 1.8. There is new parameter added to + get_eoa and set_eoa callback functions. A new callback function + get_type_map was added in. The public function H5FDrealloc was taken + out in 1.8. The problem only happens when users define their own driver + for 1.6 and try to plug in 1.8 library. Because there's only one user + complaining about it, we (Elena, Quincey, and I) decided to leave it as + it is (see bug report #1279). Quincey will make a plan for 1.10. + (SLU - 2010/02/02) + +* The --enable-static-exec configure flag will only statically link libraries + if the static version of that library is present. If only the shared version + of a library exists (i.e., most system libraries on Solaris, AIX, and Mac, + for example, only have shared versions), the flag should still result in a + successful compilation, but note that the installed executables will not be + fully static. Thus, the only guarantee on these systems is that the + executable is statically linked with just the HDF5 library. + (MAM - 2009/11/04) + +* Parallel tests failed with 16 processes with data inconsistency at testphdf5 + / dataset_readAll. Parallel tests also failed with 32 and 64 processes with + collective abort of all ranks at t_posix_compliant / allwrite_allread_blocks + with MPI IO. + (CMC - 2009/04/28) + +* On an Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers, + use -mp -O1 compilation flags to build the libraries.
