+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - Cmakehdf5: Added Ability to Run Multiple Make Commands
+
+ Added option --njobs to specify up to how many jobs to launch during
+ build (cmake) and testing (ctest).
+
+ (AKC - 2015/12/13, HDFFV-9612)
+
+ - Cmakehdf5: Added Szip Support and Verbose Option
+
+ Added --with-szlib to support the Szip library; and
+ --enable/disable-verbose to display all CMake process output.
+
+ (AKC - 2015/11/16, HDFFV-8932 and DAILYTEST-195)
+
+ - CMake minimum is now 3.1.0. (ADB - 2015/11/14)
+
+ - Large File System (LFS) Support has Changed in the Autotools
+
+ We assume that fseeko and ftello exist.
+
+ The *64 I/O functions and types are no longer explicitly used.
+ We now rely on a mapping provided by _FILE_OFFSET_BITS (or its
+ equivalent).
+
+ _LARGEFILE(64)_SOURCE is no longer exposed via AM_CPPFLAGS.
+
+ (DER - 2016/03/29, HDFFV-9626 and HDFFV-9541)
+
+
+
+ Library
+ -------
+ - New API Calls for Searching for External Dataset Storage
+
+ API calls that determine the search path for dataset external
+ storage were added. H5Pset/get_efile_prefix() API calls were added
+ to the library. These functions give control over the search path
+ for dataset external storage that has been configured with
+ H5Pset_external().
+
+ Additionally, the HDF5_EXTFILE_PREFIX environment variable can be
+ used to control the search path.
+
+ (DER - 2016/04/20, HDFFV-8740)
+
+
+
+ Parallel Library
+ ----------------
+ - None
+
+
+
+ Tools
+ -----
+ - None
+
+
+
+ High-Level APIs
+ ---------------
+
+ C Packet Table API
+ ------------------
+ - Replacement of a Public Function with H5PTcreate
+
+ The existing function H5PTcreate_fl limits applications so they
+ can use the deflate compression only. The public function
+ H5PTcreate has been added to replace H5PTcreate_fl. H5PTcreate
+ takes a property list identifier to provide flexibility on
+ creation properties. This also removes the following warning:
+ "deprecated conversion from string constant to "char*"
+ [-Wwrite-strings]".
+
+ (BMR - 2016/04/25, HDFFV-9708, HDFFV-8615)
+
+ - New Public Functions: H5PTget_dataset and H5PTget_type
+
+ Two accessor functions have been added. H5PTget_dataset returns
+ the identifier of the dataset associated with the packet table,
+ and H5PTget_type returns the identifier of the datatype used by
+ the packet table.
+
+ (BMR - 2016/04/25, HDFFV-8623 patch 3)
+
+ - Regarding #ifdef VLPT_REMOVED
+
+ The #ifdef VLPT_REMOVED blocks have been removed from the packet
+ table (PT) library source except for the following functions:
+ + H5PTis_varlen() has been made available again
+ + H5PTfree_vlen_readbuff() is now H5PTfree_vlen_buff()
+
+ (BMR - 2016/04/25, HDFFV-442)
+
+ C++ Packet Table API
+ --------------------
+ - New Constructor in FL_PacketTable
+
+ An overloaded constructor has been added to FL_PacketTable and
+ takes a property list identifier to provide flexibility on
+ creation properties such as compression.
+
+ FL_PacketTable(hid_t fileID, const char* name, hid_t dtypeID,
+ hsize_t chunkSize = 0, hid_t plistID = H5P_DEFAULT)
+
+ (BMR - 2016/04/25, HDFFV-8623 patch 5)
+
+ - New Member Functions in PacketTable
+
+ Two accessor wrappers were added to class PacketTable.
+
+ PacketTable::GetDataset() returns the identifier of the dataset
+ associated with the packet table, and PacketTable::GetDatatype()
+ returns the identifier of the datatype that the packet table uses.
+
+ (BMR - 2016/04/25, HDFFV-8623 patch 4)
+
+ - New Member Functions with "char*" as an Argument
+
+ Overloaded functions were added to provide the "const char*"
+ argument; the existing version will be deprecated in future
+ releases. This also removes the following warning:
+ "deprecated conversion from string constant to "char*"
+ [-Wwrite-strings]".
+
+ (BMR - 2016/04/25, HDFFV-8623 patch 1, HDFFV-8615)
+
+ - Regarding #ifdef VLPT_REMOVED
+
+ The #ifdef VLPT_REMOVED blocks have been removed from the packet
+ table library source code except for the following functions:
+ + VL_PacketTable::IsVariableLength() was moved to PacketTable
+ + VL_PacketTable::FreeReadBuff() is now PacketTable::FreeBuff()
+
+ (BMR - 2016/04/25, HDFFV-442)
+
+
+
+ Fortran API
+ -----------
+ - None
+
+
+
+ C++ API
+ -------
+ - New Member Function in DSetCreatPropList
+
+ DSetCreatPropList::setNbit() was added to setup N-bit compression for
+ a dataset.
+
+ (BMR - 2016/04/25, HDFFV-8623 patch 7)
+
+ - New Overloaded "const" Member Functions in ArrayType
+
+ The two following functions were added:
+ ArrayType::getArrayNDims() const
+ ArrayType::getArrayDims() const
+ to provide const version, and the non-const version was marked
+ deprecated. In-memory array information, ArrayType::rank and
+ ArrayType::dimensions, were removed. This is an implementation
+ detail and should not affect applications.
+
+ (BMR, 2016/04/25, HDFFV-9725)
+
+ - New member function added
+
+ The assignment operator ArrayType::operator= is added because ArrayType
+ has pointer data members.
+
+ (BMR, 2016/03/07, HDFFV-9562)
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - Mac OS X El Capitan 10.11.4 with compilers Apple clang/clang++
+ version 7.3.0 from Xcode 7.3, gfortran GNU Fortran (GCC) 5.2.0
+ and Intel icc/icpc/ifort version 16.0.2
+
+
+
+Bug Fixes since HDF5-1.8.16
+===========================
+
+ Configuration
+ -------------
+ - Updated Linux Language Level Flags to Match the Autotools. Removed
+ Linux-specific Flags from OS X.
+
+ An addition to the flags simply being out of sync with the Autotools,
+ the Linux flags were used on OS X builds which led to symbols not being
+ found. Although this was non-fatal and compilation continued (implicit
+ definitions were used by the compiler and the symbols resolved at link
+ time), a large number of warnings were raised.
+
+ Linux changes:
+
+ * CHANGED: _POSIX_C_SOURCE (from 199605 to 200112L)
+ * ADDED: _GNU_SOURCE
+ * REMOVED: _BSD_SOURCE
+ * REMOVED: _DEFAULT_SOURCE
+
+ (DER - 2015/12/08, HDFFV-9627)
+
+ - The --enable-clear-file-buffers configure Option was Non-functional
+ so the Feature was Always Enabled (its default value).
+
+ Regardless of the configure flag, the setting was always enabled when
+ the Autotools were used to configure HDF5. This was due to the "no"
+ option being processed after the "*" option in configure.ac so "*"
+ matched first. CMake was unaffected.
+
+ The option now works correctly.
+
+ NOTE that builders are always advised to leave this option enabled.
+ When disabled, buffers that are written to disk may contain the
+ memory's previous contents, which may include secure information.
+ The performance overhead of the feature (a single memset call per
+ allocation) is minimal.
+
+ (DER - 2016/02/03, HDFFV-9676)
+
+ - Added a patch to remove '"'s from arguments for MPI compilers that
+ were causing errors compiling H5lib_settings.c with SGI MPT.
+
+ (LRK - 2016/04/20, HDFFV-9439)
+
+ Library
+ -------
+ - Fixed shared file pointer problem which caused a crash when running a
+ program provided by a user.
+
+ (VC - 2016/04/01, HDFFV-9469)
+
+ - Fixed some format string warnings that prevent compiling with
+ -Werror=format-security on gcc.
+
+ These only appeared in error messages and would not cause problems
+ under normal operation.
+
+ (DER - 2016/01/13, HDFFV-9640)
+
+ - Fixed a library segmentation fault when accessing a corrupted
+ file provided by a user.
+
+ (MSC - 2016/02/19, HDFFV-9670)
+
+
+
+ Parallel Library
+ ----------------
+ - None
+
+
+
+ Performance
+ -------------
+ - None
+
+
+
+ Tools
+ -----
+ - h5dump: Sub-setting Fixed for Dimensions Greater than Two
+
+ When a dataset has more than two dimensions, sub-setting would
+ incorrectly calculate the data that needed to be displayed.
+ Added in block and stride calculations that account for dimensions
+ greater than two. NOTE: lines that have line breaks inserted
+ because of display length calculations may have index info that
+ is incorrect until the next dimension break.
+
+ (ADB - 2016/03/07, HDFFV-9698)
+
+ - h5dump: Issue with Argument Segmentation Fault
+
+ When an argument with an optional value was at the end of the command
+ line with a value, h5dump would crash. Reworked check for remaining
+ arguments.
+
+ (ADB - 2016/03/07, HDFFV-9570, HDFFV-9684)
+
+ - h5dump: Issue with Default Fill Value
+
+ Added all default cases of fill value to the display of fill value.
+
+ (ADB -, 2016/03/07, HDFFV-9241)
+
+ - h5dump: Clarified Help
+
+ Clarified usage of -O F option in h5dump utility help.
+
+ (ADB - 2016/03/07, HDFFV-9066)
+
+ - h5dump: Issue with Double Free Fault
+
+ Added a check for filename not null before calling free().
+
+ (ADB - 2016/01/27, HDFFV-9639)
+
+ - VS2015 Release Changed how Timezone was Handled
+
+ Created a function, HDget_timezone, in H5system.c. Replaced
+ timezone variable usage with function call.
+
+ (ADB - 2015/11/02, HDFFV-9550)
+
+
+
+ Fortran API
+ -----------
+ - None
+
+
+
+ C++ API
+ -------
+ - Removal of Obsolete Methods
+
+ The overloaded methods which had parameters that should be const
+ but were not have been removed.
+
+ (BMR - 2016/01/13, HDFFV-9789)
+
+
+
+ High-Level APIs:
+ ---------------
+ - Fixed Memory Leak in Packet Table API
+
+ Applied user's patch to fix memory leak in the creation of a
+ packet table.
+
+ (BMR - 2016/04/25, HDFFV-9700)
+
+
+
+ Fortran High-Level APIs:
+ ------------------------

+
+Known Problems
+==============
+* On windows platforms in debug configurations, the VFD flush1 tests will fail
+ with the split and multi VFD drivers. These tests will display a modal debug
+ dialog which must be answered or wait for the test timeout to expire.
+ (ADB - 2014/06/23 - HDFFV-8851)
+
+* 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 (Issue 8147). Since the algorithm is trying to detect the alignment
+ of integers, ideally the flag -fcatch-undefined-behavior shouldn't 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)
+
+* 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)
+
+* 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)
+
+* 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)
+
+* 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. the issue. HL and C++ shared libraries should now be
+ working as intended, however.
+ (MAM - 2011/04/20)
+
+* 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)
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.

+
+New Features
+============
+
+ Configuration and Build
+ -------------
+ - The thread-safety + high-level library combination has been marked
+ as "unsupported" in the Autotools
+
+ The global lock used by the thread-safety feature has never been
+ raised to the high-level library level, making it possible that
+ the library state could change if a context switch were to occur in
+ a high-level library call. Because of this, the combination of
+ thread-safety and high-level library is officially unsupported by
+ The HDF Group.
+
+ In the past, although this combination has never been supported, this
+ was not enforced by the build systems. These changes will cause an
+ Autotools configure step to fail if --enable-threadsafe and
+ --enable-hl are combined unless additional options are specified.
+ Since the high-level library is built by default, this means that
+ these extra configuration options will need to be used any time
+ --enable-threadsafe is selected.
+
+ To build with --enable-threadsafe, either:
+
+ 1) Use --disable-hl to disable the high-level library (recommended)
+
+ 2) Use --enable-unsupported to build the high-level library with
+ the thread-safety feature.
+
+ (DER - 2015/09/10 HDFFV-8719)
+
+ - Using CMake now builds both static and shared libraries.
+
+ The CMake files have been updated to build both static and shared
+ libraries, with tools only built statically. The packaging of the
+ libraries and tools will include cmake-config files that allows
+ projects to choose either shared or static (default) libraries
+ to be found with the find_package command using the COMPONENTS
+ keyword and a list of components. The imported libraries will
+ include any interface specific settings and dependent libraries.
+
+ The default setting for BUILD_SHARED_LIBS has changed from OFF
+ to ON, which builds both static and shared libraries. The static
+ libraries are always built because of tools requirements.
+
+ (ADB - 2015/08/24 HDFFV-5881)
+
+ - Inline functions now correctly annotated with Autotools builds.
+
+ The method used to detect the appropriate inline markup scheme was
+ nonfunctional in Autotools builds. The Autotools have been modified
+ to correctly detect the compiler's inline markup symbol and apply it
+ to the source. Note that only a very small number of internal
+ functions are marked inline so this was not a very big change or
+ likely to significantly affect performance.
+
+ As a part of this change, the H5_inline symbol no longer appears in
+ H5pubconf.h.
+
+ (DER - 2015/08/13 HDFFV-9119, HDFFV-9421)
+
+ - Removed obsolete/unmaintained files from config/
+
+ Several files were removed from the config directory. These files
+ represent old operating systems, were no longer necessary, and/or
+ were no longer maintained. configure.ac was updated to reflect the
+ removed files.
+
+ Removed:
+
+ craynv
+ dec-flags
+ hpux11.23
+ ia64-linux-gnu
+ nec-superux14.1
+ sv1-cray
+ x86_64-redstorm-linux-gnu
+ powerpc-ibm-aix5.x
+
+ As a part of this work, a few lines that deal with locating the
+ sys/fpu.h header on SGI machines and some OSF/1 configure lines
+ were also removed. The Solaris config was also renamed to not have
+ a version number since the version number was ignored by configure
+ as it applies to all Solaris versions.
+
+ (DER - 2015/09/04 HDFFV-9116)
+
+ - Removed the FP_TO_INTEGER_OVERFLOW_WORKS macro/defines from the library
+
+ This was for working around bugs in the Cray X1 compiler, which is no
+ longer supported.
+
+ (DER - 2015/09/09 HDFFV-9191)
+
+ - Removed the H5_SW_ULONG_TO_FP_BOTTOM_BIT_WORKS and
+ H5_FP_TO_ULLONG_BOTTOM_BIT_WORKS symbols and associated code.
+
+ H5_SW_ULONG_TO_FP_BOTTOM_BIT_WORKS was a work-around on old 64-bit
+ SGI and Solaris systems.
+
+ H5_FP_TO_ULLONG_BOTTOM_BIT_WORKS was a work-around for old PGI
+ compilers on Linux.
+
+ Neither of these were used in any current library code and only appeared
+ in the dt_arith test.
+
+ (DER - 2015/09/09 HDFFV-9187)
+
+ - Removed CONVERT_DENORMAL_FLOAT symbol and associated code from the
+ library.
+
+ This was only set in configure files for Cray and NEC computers. These
+ config files no longer exist so there is no effect on currently
+ supported platforms.
+
+ (DER - 2015/09/09 HDFFV-9188)
+
+ - Removed _BSD_SOURCE and _DEFAULT_SOURCE from configure.ac
+
+ These are old BSD-compatibility symbols that are no longer needed by
+ the library.
+
+ (DER - 2015/09/10 HDFFV-9079)
+
+ - Removed HW_FP_TO_LLONG_NOT_WORKS symbol and associated code from the
+ library.
+
+ This was part of a work-around for the VS.NET 2003 compiler, which is
+ no longer supported.
+
+ (DER - 2015/09/10 HDFFV-9189)
+
+ - Removed the BAD_LOG2_CODE_GENERATED symbol and associated code from the
+ library.
+
+ This was an IRIX work-around.
+
+ (DER - 2015/09/11 HDFFV-9195)
+
+ - Decoupled shared object version numbers for wrapper libraries from the
+ shared object version number for the HDF5 library. These will be
+ maintained on an individual basis according to the interface changes
+ specific to these wrapper libraries.
+
+ For HDF5 1.8.16 the shared object version numbers were changed from
+ 10.0.1 to 10.1.0 for the HDF5 library due to added APIs. For the C++
+ wrapper library they were changed from 10.0.1 to 11.0.0 due to changes
+ in existing APIs. For all other wrapper libraries the versions were
+ changed from 10.0.1 to 10.0.2 because while the APIs had no changes
+ there have been changes in code that did not result in changes to their
+ interfaces.
+
+ (LRK - 2015/10/28)
+
+ Library
+ -------
+
+ - H5F_ACC_DEBUG flag for H5Fopen/create: functionality removed
+
+ The symbol was used to emit some extra debugging information
+ for HDF Group developers in the multi VFD. The underlying
+ functionality has been removed due to disuse. The symbol
+ remains defined since it was visible in H5Fpublic.h but it
+ has been set to zero and has no effect anywhere in the library.
+
+ (DER - 2015-05-02, HDFFV-1074)
+
+ - New public API call: H5is_library_threadsafe()
+
+ This API call indicates if the library was built with thread-
+ safety enabled.

+ - Class H5::ObjCreatPropList is added for the object creation property
+ list class.
+
+ Class H5::ObjCreatPropList is derived from H5::PropList and is a
+ baseclass of H5::DSetCreatPropList. Additional property list classes
+ will be derived from H5::ObjCreatPropList when they are added to the
+ library in future releases.
+
+ (BMR, 2015/10/13, Part of HDFFV-9169)
+
+ - New Wrappers for C Functions H5P[s/g]et_attr_phase_change and
+ H5P[s/g]et_attr_creation_order.
+
+ Wrappers were added to class H5::ObjCreatPropList for the C Functions

+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - Added VS2015 with Intel Fortran 16 to supported Windows 7 platforms
+
+
+Bug Fixes since HDF5-1.8.15
+===========================
+
+ Configuration
+ -------------
+
+ - CMake test for long long printf format improved
+
+ The CMake configuration test for determining the printf format string
+ for printing a long long integer was fixed. The test would crash
+ when executed with VS2015.
+
+ (ADB - 2015-10-21 HDFFV-9488)
+
+ Library
+ -------
+ - VS2015 removed global variable timezone
+
+ The usage of the global variable timezone was modified for VS2015 by
+ adding an alias to Windows builds.
+
+ (ADB - 2015-10-23 HDFFV-9550)
+
+ - Fix potential error in H5Iclear_type
+
+ If the ID type's close callback could close another ID of the same type,
+ H5Iclear_type could occasionally run into problems due to the inner
+ workings of the skip list package. This could potentially cause an
+ error on library shutdown without calling H5Iclear_type directly. This
+ issue has been fixed.
+
+ (NAF - 2015-08-12)
+
+ - Fix uninitialized memory in dataspace selection code
+
+ When creating a dataspace with H5Screate and setting the extent with
+ H5Sextent_copy, the selection offset was not initialized, potentially
+ causing invalid I/O. There may be other cases where this happened.
+ Modified the library to always initialize the offset.
+
+ (NAF - 2015-09-08)
+
+ - Truncate file in H5Fflush() if EOA != EOF to avoid file
+ corruption in certain scenarios
+
+ In the following scenario, the resulting HDF5 file would be
+ incorrectly corrupted because the truncate operation
+ was at some point wrongly moved out of the flush operation:
+ - Create a new file with a single dataset.
+ - Write parts of the dataset (make sure that some values at
+ the end of the dataset are not initialized).
+ - Flush the file.
+ - Crash the program.
+ - Try to open the file with h5dump or h5debug, but the
+ resulting file is corrupted.
+
+ (MSC - 2015-06-15 HDFFV-9418)
+
+
+ Parallel Library
+ ----------------
+ -
+ (XYZ - YYYY/MM/DD HDFFV-####)
+
+ Performance
+ -------------
+ - None
+
+ Tools
+ -----
+ - VS2015 changed the default format for printing of exponents
+
+ VS2015 default format for exponents changed with the elimination
+ of the leading '0'. CMake now tests for the VS2015 compiler and
+ adjusts which reference files are used by tests.
+
+ (ADB - 2015-10-23 HDFFV-9550)
+
+ - Fixed h5repack with user-defined filters
+
+ h5repack would throw a buffer overrun exception on Windows when
+ parsing a user-defined filter ID of 5 digits. A local variable in
+ the parse routine was not of sufficient size.
+
+ (ADB - 2015/09/01 HDFFV-9515)
+
+ Fortran API
+ ------------
+ - None
+
+
+ C++ API
+ ------
+ - Removed memory leaks
+
+ The static global constant objects were changed to constant references
+ referencing dynamically allocated objects. This ensures that the clean-up
+ process in the C++ library occurs before the termination of the C library
+ and prevents memory leaks because the previous global constants were not
+ properly deleted before the C library termination.
+
+ (BMR, 2015/10/13, HDFFV-9529)
+
+ - Fixed the problem about identifiers being closed prematurely.
+
+ The C++ library needs to increment the ID's reference counter when it is
+ duplicated in the form of C++ objects, but not when the ID is obtained
+ from a C function. With this approach, both problems, prematurely
+ closing ID's and memory leaks due to ID's not being closed, should be
+ eliminated.
+
+ (BMR, 2015/10/15, HDFFV-7947)

+
+
+Known Problems
+==============
+* On Windows platforms in debug configurations, the VFD flush1 tests will fail
+ with the split and multi VFD drivers. These tests will display a modal debug
+ dialog which must be answered or wait for the test timeout to expire.
+ (ADB - 2014/06/23 - HDFFV-8851)
+
+* 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 (Issue 8147). Since the algorithm is trying to detect the alignment
+ of integers, ideally the flag -fcatch-undefined-behavior shouldn't 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)
+
+* 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)
+
+* 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)
+
+* 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)
+
+* 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. HL and C++ shared libraries should now be working as intended,
+ however.
+ (MAM - 2011/04/20)
+
+* 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 of 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)
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian systems. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.

+- New Features
+- Support for New Platforms, Languages, and Compilers
+- Bug Fixes since HDF5-1.8.14
+- Supported Platforms
+- Supported Configuration Features Summary
+- More Tested Platforms
+- Known Problems
+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - CMake
+
+ Improvements made to the CMake build system.
+
+ The default options were changed to align with the Autotools configure
+ defaults. CMake configure files now support components when packaged
+ with CPack. Windows CPack supports WiX packaging, and will look for
+ WiX and NSIS in the standard locations.
+
+ The CMake minimum has been changed to 3.1.
+
+ (ADB - 2015/04/01 HDFFV-8074, 8968, 9006)
+
+ - cmakehdf5 for Cmake building.
+ Added configure options to support the building of Fortran or CXX API,
+ to enable/disable testings. Use "cmakehdf5 --help" for details.
+ (AKC - 2014/12/09 HDFFV-8932)
+
+ - Building Shared and Parallel Made Explicit
+
+ When --enable-parallel is specified, configure used to disable
+ shared by default.
+
+ Removed the restriction for building shared when parallel is
+ enabled. --disable-shared has to be used explicitly if user
+ wishes to disable shared libraries.
+
+ (MSC - 2015/02/19 HDFFV-9069)
+
+ - Inferring Parallel Compilers
+
+ configure was trying to infer if a compiler is a parallel
+ compiler with MPI support and enable parallel even if the user
+ did not explicitly enable parallel. This should not happen.
+
+ Disabled inferring parallel compilers to enable parallel HDF5
+ build. --enable-parallel has to be used explicitly to build
+ parallel HDF5 regardless of the compiler type being used.
+
+ (MSC - 2015/02/19 HDFFV-9068)
+
+ - Large File Support Configuration Option
+
+ Removed the option to enable or disable large file support. It will
+ always be enabled.
+
+ (MSC - 2015/02/19 HDFFV-9097)
+
+ - Removed Configuration Feature
+
+ When configure detected that the CodeWarrior compiler was being used it
+ would define a symbol that caused a test in test/tfile.c to be skipped
+ due to a broken CodeWarrior open() command.
+
+ Since this only masks the problem instead of fixing it and we don't
+ support CodeWarrior anyway, this functionality was removed.
+
+ (DER - 2015/02/21, HDFFV-9080)
+
+ - VMS Build/Test Files Have Been Removed
+
+ HDF5 no longer supports VMS, and the files were getting out of date.
+ Since we have no access to a VMS machine, there is no way for us to
+ maintain them.
+
+ A Subversion tag was created at:
+
+ https://svn.hdfgroup.uiuc.edu/tags/vms_last_support_1_8
+
+ immediately before removing the files.
+
+ (DER - 2015-02-26, HDFFV-9147)
+
+ - Removal of --with-default-vfd configure Option
+
+ In theory, this option was intended to allow setting a default
+ VFD that would be used by the library. In practice, the feature
+ only accepted the POSIX (SEC2) VFD (already the default) and
+ the stdio VFD (a demo VFD not intended for production use). The
+ inability to pass key VFD parameters at configure time limits the
+ full implementation of this feature, so it was retired.
+
+ (DER - 2015-02-26, HDFFV-9081)
+
+ - Direct VFD configure Behavior
+
+ The configure options for Linux now allow the Direct VFD to build
+ without passing additional compiler options/defines like _GNU_SOURCE.
+ Passing --enable-direct-vfd is now all that is needed to enable
+ the feature.
+
+ The Direct VFD is now disabled by default since it is intended for
+ specialized audiences. It was previously enabled by default, but the
+ configure script did not set correct POSIX levels, etc. making this
+ a moot point.
+
+ Note that the Direct VFD can only be configured on Linux when
+ the O_DIRECT flag to open()/create() and posix_memalign() function
+ are available. This is unchanged from previous behavior.
+
+ (DER - 2015-02-26, HDFFV-9057, 7567, 9088, 7566)
+
+ - _POSIX_C_SOURCE, _GNU_SOURCE, and _BSD_SOURCE No Longer Exported
+ to h5cc and Other Compiler Wrappers
+
+ The _POSIX_C_SOURCE, _GNU_SOURCE, and _BSD_SOURCE definitions are
+ not required for using API functions and may conflict with user
+ code requirements.
+
+ (DER - 2015-03-08, HDFFV-9152)
+
+ - Removed the --enable-filters Option from configure
+
+ This option allowed the user to disable selected internal filters,
+ presumably to make the library smaller. It has been removed since
+ it saved little space (the internal filters are small with respect
+ to the overall library size) and was not generally extendible to
+ the library at large due to the large number of #ifdefs that would
+ be required.
+
+ Note that this features applied to internal filters such as shuffle
+ and n-bit and not external filters like gzip or Szip. Those are still
+ enabled or disabled via their own configure options.
+
+ (DER - 2015-03-08, HDFFV-9086)
+
+ - Removed Obsolete Time Functionality from configure and the C Library
+
+ The library contained some residual functionality from obsolete
+ time zone handling code. This has been removed, and the configure
+ checks for the time functions have been cleaned up.
+
+ * Lumped all the time functionality together in configure.ac.
+ This was previously more spread out due to Solaris issues
+ with the ordering of certain checks.
+
+ * Removed processing that handles __tm_gmtoff members of struct
+ tm. (libc-4)
+
+ * Removed BSDgettimeofday(). (IRIX 5.3)
+
+ * Removed timezone struct handling in gettimeofday() (considered
+ harmful).
+
+ Note that the HDF5 Library stores timestamps in a platform-independent
+ manner, so old files can still be read. This only affects converting
+ system time to HDF5 timestamps.
+
+ The library currently uses the tm_gmtoff member of the tm struct
+ (preferred, if available) or the timezone global variable to
+ construct HDF5 timestamps.
+
+ (DER - 2015-03-09, HDFFV-9083 and 9085)
+
+ - Added -D_DEFAULT_SOURCE to CPPFLAGS on Linux Systems
+
+ This is the replacement for -D_BSD_SOURCE in versions of glibc since 2.19.
+ Since both are defined, it should work for all versions of glibc. Defining
+ both suppresses the warning about defining _BSD_SOURCE.
+
+ (NAF - 2015-04-02, HDFFV-9079)
+
+ Library
+ -------
+ - Added Memory Allocation Functions that Use the Library's Allocator
+
+ HDF5 filters may need to allocate or resize the buffer that is passed
+ to them from the library. If the filter has been compiled separately
+ from the library, it and the library may use different memory
+ allocation libraries for the (re)allocation and free calls. This can
+ cause heap corruption and crashes. This is particularly a problem on
+ Windows since each C run-time library is implemented as a separate
+ shared library, but can also show up on POSIX systems when debug or
+ high-performance allocation libraries are in use.
+
+ Two new functions (H5allocate_memory() and H5resize_memory()) were
+ added to the HDF5 C library. These functions have the same semantics as
+ malloc/calloc and realloc, respectively. Their primary purpose is to
+ allow filter authors to allocate or resize memory using the same
+ memory allocation library as the HDF5 library. Filter authors are
+ highly encouraged to use these new functions in place of malloc,
+ calloc, and realloc. They should also use the H5free_memory() call when
+ freeing memory.
+
+ Note that the filters provided with the library (zlib, szip, etc.) do
+ not experience the problems that these new functions are intended to
+ fix. This work only applies to third-party filters that are compiled
+ separately from the library.
+
+ (DER - 2015-04-01, HDFFV-9100)
+
+ - H5Pset_istore_k and H5Pset_sym_k
+
+ These two functions didn't check the value of the input parameter "ik".
+ When 2*ik exceeded 2 bytes of storage, data was lost in the file;
+ for example, some chunks would be overwritten.
+
+ Added validation of "ik" to not exceed the max v1 btree entries (2 bytes)
+ to these two routines.
+
+ (VC - 2015-03-24, HDFFV-9173)
+
+ - Added Functions to Control the Value of H5PL_no_plugin_g without
+ Using an Environment Variable
+
+ Sometimes it is necessary for an application to disable the use of
+ dynamically loaded plugin libraries without requiring the library to
+ be built with plugin support disabled or to set an environment
+ variable to disable plugin support globally.
+
+ Two new functions (H5PLset_loading_state() and H5PLget_loading_state())
+ were added to the HDF5 C Library. These functions require a parameter
+ that indicates which type of dynamically loaded plugin is enabled or
+ disabled.
+
+ (ADB - 2015-03-17, HDFFV-8520)
+
+ Parallel Library
+ ----------------
+ - MPI_Finalize and HDF5 Library Shutdown
+
+ Calling HDF5 routines after MPI_Finalize has been closed should
+ not be done, since those routines might call MPI functions that
+ would not be possible to do after finalizing the MPI library.
+
+ Attached an attribute destroy callback to MPI_COMM_SELF that
+ shuts down the HDF5 library when MPI_COMM_SELF is destroyed,
+ in other words, on MPI_Finalize. This should fix several issues
+ that users see when they forget to close HDF5 objects before
+ calling MPI_Finalize().
+
+ (MSC - 2015/02/25, HDFFV-883)
+
+ Tools
+ -----
+ - None
+
+ High-Level APIs
+ ---------------
+ - None
+
+ Fortran API
+ -----------
+ - Added Global Variables
+
+ These new global variables are equivalent to the C definitions
+ without the '_F':
+
+ H5G_UDLINK_F
+ H5G_SAME_LOC_F
+ H5O_TYPE_UNKNOWN_F
+ H5O_TYPE_GROUP_F
+ H5O_TYPE_DATASET_F
+ H5O_NAMED_DATATYPE_F
+ H5O_TYPE_NTYPES_F
+
+ (MSB - 2015/02/03, HDFFV-9040)
+
+
+ C++ API
+ -------
+ - New Wrappers for C Functions H5P[s/g]et_libver_bounds
+
+ Wrappers were added to class H5::FileAccPropList for the
+ C Functions H5Pget_libver_bounds and H5Pset_libver_bounds.
+
+ (BMR, 2015/04/06, Part of HDFFV-9167)
+
+ - New Wrappers to Get the Object Header's Version
+
+ The following wrappers are added to class H5::CommonFG
+ Returns the object header version of an object in a file or group,
+ given the object's name.
+
+ unsigned childObjVersion(const char* objname) const;
+ unsigned childObjVersion(const H5std_string& objname) const;
+
+ (BMR, 2015/04/06)
+
+ - New DataType Constructor
+
+ Added a DataType constructor that takes a PredType object, and this
+ constructor will invoke H5Tcopy to generate another datatype id
+ from a predefined datatype.
+
+ (BMR, 2015/04/06)
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - Support for Linux 3.10.0-123.20.1.el7 added (LK - 2015/04/01)
+ - Support for Mac OS X Yosemite 10.10 added (AKC - 2015/03/04, HDFFV-9007)
+ - Support for AIX 6.1 added and AIX 5.3 is retired. (AKC - 2015/01/09)
+
+Bug Fixes since HDF5-1.8.14
+===========================
+
+ Configuration
+ -------------
+ - Make uninstall generated "test: argument expected".
+ The error is due to $EXAMPLETOPDIR is used without setting a value first.
+
+ Fixed by assign it with the proper value.
+
+ (AKC - 2015/04/29, HDFFV-9298)
+
+ - Windows Installer Incorrect Display of PATH Environment Variable
+
+ In the Windows installer, the dialog box where the user can elect to
+ add the product's bin path to the %PATH% environment variable displayed
+ an incorrect path. This path was missing the C:\Program Files part
+ and used the POSIX file separator '/' before the bin (<path>/bin,
+ instead of <path>\bin).
+
+ The dialog box text was changed to simply say that the product's bin
+ path would be added instead of explicitly displaying the path.
+ This is in line with most installers. The reason for not fixing the
+ displayed path instead is that it is difficult to pass the correct
+ path from CPack to the NSIS installer for display.
+
+ Note that this was never a code issue - it was just a display
+ problem. The installer always did the right thing when updating the
+ environment variable.
+
+ (DER - 2014/11/14, HDFFV-9016)
+
+ Library
+ -------
+ - Incorrect Usage of List in CMake COMPILE_DEFINITIONS set_property
+
+ The CMake command set_property with COMPILE_DEFINITIONS property
+ needs a quoted semi-colon separated list of values. CMake will
+ transform the list to a series of -D{value} for the compile.
+
+ (ADB - 2014/12/09, HDFV-9041)
+
+ - Fixed Compile Errors on Windows w/ Visual Studio and CMake When
+ UNICODE is Defined
+
+ The HDF5 Library could not be built on Windows with Visual Studio when
+ UNICODE was defined. This was due to the incorrect use of the TEXT()
+ macro and some Win32 API functions that take TCHAR parameters. The faulty
+ code was a part of the filter plugin functionality. This was a
+ compile-time error that only affected users who build HDF5 from source
+ and define UNICODE, usually when HDF5 is being built as a part of a
+ larger product. There were no run-time effects.
+
+ These errors caused no problems when UNICODE was not defined. HDF5 is
+ normally not built with UNICODE defined and the binaries were
+ unaffected.
+
+ The fix was to remove the TEXT() macro and explicitly use the
+ 'A' form of the Win32 API calls, which expect char strings instead of
+ wchar_t strings.
+
+ Note that HDF5 currently does not support Unicode file paths on Windows.
+
+ (DER - 2015/02/22, HDFFV-8927)
+
+ - Addition of Error Tracing Functionality to Several C API Calls
+
+ A bug in a text processing script caused API calls that return a
+ pointer to not receive error tracing macros/functionality.
+
+ The bug has been corrected and error tracing functionality has been
+ added to the affected API calls. These functions will now correctly
+ print trace information when library errors are encountered.
+
+ (DER - 2015/02/26, HDFFV-9141)
+
+ - H5Rdereference Now Checks for HADDR_UNDEF or Uninitialized References
+
+ When passed HADDR_UNDEF or uninitialized references, the previous
+ behavior of H5Rdereference was to continue to process the reference
+ as a valid address.
+
+ H5Rdereference was changed to return immediately (with an error
+ message) if the references are HADDR_UNDEF or uninitialized.
+
+ (MSB - 2015/3/10, HDFFV-7959)
+
+ - Fixed Bugs in H5Sextent_copy
+
+ H5Sextent_copy would not free the previous extent, resulting in a memory
+ leak. Also, H5Sextent_copy would not update the number of elements
+ selected if the selection was "all", causing various problems. These
+ issues have been fixed.
+
+ (NAF - 2015/04/02)
+
+
+ Parallel Library
+ ----------------
+ - Fixed a Potential Memory Error
+
+ Fixed a potential memory error when performing parallel I/O on a
+ dataset with a single chunk, and at least one process has nothing
+ to do.
+
+ (NAF - 2015/02/16)
+
+ - Parallel Test Problem Fixed
+
+ Fixed problem with parallel tests where they failed beyond a
+ certain number of ranks. All tests should work for any arbitrary
+ number of ranks.
+
+ (MSC - 2014/11/06, HDFFV-1027,8962,8963)
+
+ - MPE Support
+
+ Enabling MPE was causing HDF5 build to fail. Support for it was
+ dropped at some point in time.
+
+ Fixed problem with enabling MPE. Users should use the community
+ maintained MPE on github (http://git.mpich.org/mpe.git/).
+
+ (MSC - 2015/02/20, HDFFV-9135)
+
+ Performance
+ -------------
+ - None
+
+ Tools
+ -----
+ - h5repack crashed on enumerated 8-bit type.
+
+ Previous version 1.8.14 introduced an error that caused the reading
+ of enumerated 8-bit type nested in compound type to fail.
+
+ Fixed library code responsible for reading the particular type.
+ (AKC - 2015.03/31, HDFFV-8667)
+
+ - h52gif crashed non-8bit images.
+
+ h52gif crashed if instructed to convert images other than 8bit images.
+
+ h52gif could handle only 8bit images. Added code to detect non-8bit
+ images and flag them as failure. Update tool document page to reflect
+ the limit.
+ (AKC - 2015/03/31, HDFFV-8957)
+
+ - perform/benchpar.c retired.
+
+ benchpar.c has not been built for a long time and its original purpose
+ is not needed any more.
+ (AKC - 2014/12/19, HDFFV-8156)
+
+ - Source perform/ directory moved to tools/perform.
+ The perform directory is moved to tools/perform for easier maintenance.
+ (AKC - 2014/12/17, HDFFV-9046)
+
+ Fortran API
+ ------------
+ - Fortran Fails with --enable-fortran2003 and Intel 15.x Compilers
+
+ Added BIND(C) to the offending APIs.
+
+ The Fortran Library (--enable-fortran2003) now works using Intel 15.x
+ without the need for any additional compilers flags.
+
+ (MSB - 2015/1/26, HDFFV-9049)
+
+ - h5tenum_insert_f Does Not Work with Default 8 Byte Integers
+ (xlf compiler)
+
+ In the Fortran 90 API, 'value' is no longer cast into the C int type.
+ Therefore, if h5tenum_insert_f is passed an 8 byte integer (via -i8)
+ then 'value' is written as the same type as the default Fortran
+ integer type (which can be 8 bytes).
+
+ A new Fortran 2003 API was added which is more in line with the C
+ API and users are strongly encouraged to use the Fortran 2003 API
+ instead of the Fortran 90 API.
+
+ SUBROUTINE h5tenum_insert_f(type_id, name, value, hdferr)
+ INTEGER(HID_T) , INTENT(IN) :: type_id
+ CHARACTER(LEN=*), INTENT(IN) :: name
+ TYPE(C_PTR) , INTENT(IN) :: value
+ INTEGER, INTENT(OUT) :: hdferr
+
+ (MSB - 2015/2/19, HDFFV-8908)
+
+ - Some Fortran APIs Never Returned the Error State
+
+ Some Fortran APIs never returned the error state: they
+ would always return a positive number. The APIs include
+ the following:
+
+ h5fget_file_image_f
+ h5lget_name_by_idx_f
+ h5oget_comment_by_name_f
+
+ They were corrected to return a negative number as described in
+ the Reference Manual if an error occurred.
+
+ (MSB - 2015/3/19, HDF5-239)
+
+ - Fixed h5pget_class_f
+
+ h5pget_class_f never correlated the class identifier to the property
+ list class name as indicated in the HDF5 Reference Manual; it instead
+ returned a property list class identifier as an INTEGER. The INTEGER
+ needed to be of type INTEGER(HID_T) to be correct.
+
+ The h5pget_class_f API was changed to return an INTEGER(HID_T)
+ property list class identifier instead of an INTEGER. This mimics the
+ intended behavior of the C API.
+
+ (MSB - 2015/3/16, HDFFV5-9162)
+
+ C++ API
+ ------
+ - Combined Two H5File::getObjCount Overloaded Methods
+
+ The following two methods
+
+ ssize_t getObjCount(unsigned types) const;
+ ssize_t getObjCount() const;
+
+ were combined into one:
+
+ ssize_t getObjCount(unsigned types = H5F_OBJ_ALL) const;
+
+ (BMR - 2015/04/06)
+
+ - Many Warnings Were Removed
+
+ Many warnings such as conversion, unused variables, missing base
+ class initialization, and initializing base classes in wrong order
+ were removed.
+
+ (BMR, 2015/04/06)
+
+ - Functionality Deprecation
+
+ The following two constructors of classes AbstractDs, IdComponent,
+ H5Location, and H5Object are no longer appropriate after the data member
+ "id" had been moved from IdComponent to the sub-classes in previous
+ releases.
+
+ <Classname>(const hid_t h5_id);
+ <Classname>(const <Classname>& original);
+
+ The copy constructors were no-op and removed in 1.8.15. The other
+ constructors will be removed from 1.10 release, and then from 1.8.17
+ if their removal does not cause any problems.
+
+ (BMR, 2015-04-06)
+
+
+ High-Level APIs:
+ ------
+ - Suppress Warnings from Flex/Bison-generated Code
+
+ Warning suppression #pragmas, etc. have been added to H5LTparse.c and
+ H5LTanalyze.c. We have no control over this code since it's created by
+ a generator.
+
+ (DER - 2015/03/08 - HDFFV-9149)
+
+ - Changed hdf5_hl.h to Include the HDF5 Main Library "hdf5.h"
+
+ User's no longer need to include both hdf5_hl.h and hdf5.h
+
+ (MSB - 2015/2/14, HDFFV-8685)
+
+
+ - H5PTcreate_fl Does Not Convert to Memory Datatype
+
+ H5PTcreate_fl now converts to the table's native memory datatype
+ to fix the problem of handling BE and LE packet tables.
+
+ (MSB - 2015/2/26 - HDFFV-9042)
+
+ - Fix for H5LT Attribute Functions
+
+ H5LT attribute functions fail to create attributes whose name
+ is a substring of an existing attribute.
+
+ H5LT attribute functions can now create attributes whose name
+ is a substring of an existing attribute.
+
+ (MSB - 2015/2/24, HDFFV-9132)
+
+
+ Fortran High-Level APIs:
+ ------------------------
+
+ - Internal Library Fix for Missing Argument Declaration
+
+ In Interface block for h5tbmake_table_c, "max_char_size_field_names"
+ is listed as an input, but in the argument definitions it is
+ "INTEGER :: max_char_size". This caused no known problems with the
+ Fortran HL API.
+
+ Fixed missing argument definition.

+Known Problems
+==============
+* On Windows platforms in debug configurations, the VFD flush1 tests will fail
+ with the split and multi VFD drivers. These tests will display a modal debug
+ dialog which must be answered or wait for the test timeout to expire.
+ (ADB - 2014/06/23 - HDFFV-8851)
+
+* 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 (Issue 8147). Since the algorithm is trying to detect the alignment
+ of integers, ideally the flag -fcatch-undefined-behavior shouldn't 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)
+
+* 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)
+
+* 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)
+
+* 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)
+
+* 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. the issue. HL and C++ shared libraries should now be
+ working as intended, however.
+ (MAM - 2011/04/20)
+
+* 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)
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.

+
+New Features
+============
+
+ Configuration
+ -------------
+ - bin/cmakehdf5 configures, builds and installs C, C++, Fortran and High
+ level API's. (It used to build the C API only).
+ (AKC 2014/10/17 HDFFV-8932).
+
+ Library
+ -------
+ - None
+
+ Parallel Library
+ ----------------
+ - Chunk Fill Writes Changed to Collective
+
+ Slow performance in chunk fill writes. Chunk fills
+ in the past were written independently by rank 0 one block
+ at a time.
+
+ Optimized the chunk fill write algorithm so that all
+ chunk fill values will be written collectively in a single MPI-IO
+ call. This should show a great performance improvement when
+ creating chunked datasets in parallel when the chunk dimensions
+ are fairly small.
+
+ (MSC - 2014/08/22, HDFFV-8878)

+ Tools
+ -----
+ - None
+
+ High-level APIs
+ ---------------
+ - None
+
+ Fortran API
+ -----------
+ - None
+
+ C++ API
+ -------
+ - Initialization of Object IDs
+
+ The data member "id" in classes that represent HDF5 objects were
+ initialized to 0, which caused problem for some users.
+
+ Replaced 0 with H5I_INVALID_HID to initialize these "id"s. For the
+ PropList class, H5P_DEFAULT is used instead of H5I_INVALID_HID.
+
+ (BMR - 2014/09/30, HDFFV-4259)

+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - None
+
+Bug Fixes since HDF5-1.8.13
+===========================
+
+ Configuration
+ -------------
+ - CMake and SVN URLs
+
+ The SVN URLs will be different when the HDF Group domain name changes.
+
+ Removed the SVN URL references in the cacheinit.cmake and release_docs files.
+
+ (ADB - 2014/10/27, HDFFV-8953)
+
+ - CMake Packaging
+
+ A Fortran module was not generated if the compiler was not F2003
+ compliant.
+
+ Removed the module name from the package list of Fortran modules because
+ that module was never generated. This was only an issue for Fortran
+ compliers that are not F2003 compatible.
+
+ (ADB - 2014/10/16, HDFFV-8932)
+
+ - Shared Library Interface Version Number (soname)
+
+ In order to increase the maintainability of HDF5, an architectural
+ change was made which required the renaming of several public symbols in
+ H5Ppublic.h.
+
+ The shared libary interface version number ("soname") has been increased
+ on account of these changes. For a full list of the changed symbols, see
+ the interface compatibility report, which is available as a link off of
+ the 'HDF5 Software Changes from Release to Release' document:
+
+ http://www.hdfgroup.org/HDF5/doc/ADGuide/Changes.html
+
+ (AKC - 2014/10/03, HDFFV-8937)
+
+ - Configure Settings for Mac OSX Need Defaults for PROD_XXX, DEBUG_XXX,
+ and PROFILE_XXX
+
+ The configure setting files for Mac OSX (config/apple) did not
+ have the default settings of PROD_XXX, DEBUG_XXX, PROFILE_XXX.
+
+ Added the default settings. Mac platforms now builds library with
+ "-O3" optimization when the default clang compiler is used.
+
+ (AKC - 2014/10/01, HDFFV-8933)
+
+ - CMake ConfigureChecks
+
+ Two include files were missing from two C tests.
+
+ Propagated the configure test changes to H5_LDOUBLE_TO_INTEGER_WORKS_TEST
+ and H5_ULLONG_TO_LDOUBLE_PRECISION_TEST to ConfigureChecks.cmake (added
+ stdlib.h and string.h in the HDFTests.c file).
+
+ (ADB - 2014/09/02 HDFFV-8845)
+
+ - CMake Parallel Test Missing
+
+ The source file was removed in the previous release but the parallel
+ test t_posix_compliant was not.
+
+ Removed the t_posix_compliant parallel test from the library.
+
+ (ADB - 2014/8/14 HDFFV-8880)
+
+ - Autotools Reconfigure. Bison. Flex.
+
+ The Bison and Flex files were out of date.
+
+ Bison was upgraded to 2.7, and Flex was upgraded to 2.5.37. The
+ bin/reconfigure script now will execute Bison and Flex and update
+ the hl/src files.
+
+ (ADB - 2014/06/16 HDFFV-8709)
+
+ - Autotools Reconfigure. m4.
+
+ The m4 macro processor was out of date.
+
+ Reconfigured Autotools with m4 upgraded to 1.4.17.
+
+ (ADB - 2014/06/12 HDFFV-8743)
+
+ - Autotools: Modified configure to add an entry at the beginning of AM_LDFLAGS
+ for the hdf5 install directory. Without this entry the relink commands
+ invoked by "make install" to create libraries dependent on libhdf5.so added
+ a dependency on the first libhdf5.so found in any directory in AM_LDFLAGS
+ regardless of its version. (LRK - 2014/10/17 HDFFV-8944)
+
+ - Changed Autotools Build Behavior. Fortran High-level Library.
+
+ The Fortran high-level (HL) library did not compile if the default
+ size of a REAL is DOUBLE PRECISION; the build would fail during
+ compilation.
+
+ Configure now checks to see if REAL is DOUBLE PRECISION, Fortran is
+ enabled, and HL library is enabled. If this is true, then configure
+ will stop with an error message.
+
+ (MSB - 2014/8/11, HDFFV-8883/HDFFV-889)
+
+
+
+ Library
+ -------
+ - Fixed Identifier Management Code
+
+ Opening an object returns an identifier; closing the object should
+ free up the identifier. A problem was found where the identifiers
+ were not being freed up correctly.
+
+ Fixed the problem so that identifiers that have been used can be
+ used again after their object has been closed.
+
+ (QAK - 2014/10/16, HDFFV-8930)
+
+ - Removal of DllMain() from Static Windows Builds
+
+ A DllMain() function was added in HDF5 1.8.13 in order to handle
+ win32 thread cleanup. The preprocessor #ifdefs around the DllMain
+ function allowed it to be compiled when the static library is built,
+ which is incorrect behavior that can cause linkage problems in
+ clients.
+
+ The fix was to change the preprocessor #ifdefs to exclude compiling
+ DllMain() in static builds. Our DllMain function is now only
+ compiled when the shared, thread-safe library is built on Windows.
+
+ (DER - 2014/06/13, HDFFV-8837)
+
+ - Enforce Constraint on page_size Parameter in H5Pset_core_write_tracking()
+
+ The reference manual states that the page_size parameter cannot be
+ zero.
+
+ This change checks the page_size parameter to see it is zero and
+ returns an error code if it is.
+
+ (DER - 2014/08/11, HDFFV-8891)
+
+ - H5Ldelete_by_idx() fails on non-existent group name.
+ (MSC - 2014/07/31, HDFFV-8888)
+
+ - H5Ldelete_by_idx() Seg Fault on Non-existent Group Name
+
+ If a non-existent group name was used by H5Ldelete_by_idx(), a
+ segmentation fault would result.
+
+ Bug was fixed.
+
+ (MSC - 2014/07/31, HDFFV-8888)
+
+ - Bug in Test When Building Parallel HDF5 on PVFS2
+
+ There was a bug in a test when building Parallel HDF5 on PVFS2.
+
+ The build now uses MPI_File_get_size() instead of stat().
+
+ (MSC - 2014/07/14, HDFFV-8856)
+
+ - MPI-IO Driver Tried to Allocate Space for Zero-length Dataset
+
+ MPI-IO driver tried to allocate space for zero-length dataset
+ and asserts.
+
+ Fixed driver and added a regression test.
+
+ (MSC - 2014/07/03, HDFFV-8761)
+
+
+ Parallel Library
+ ----------------
+ - None
+
+ Performance
+ -------------
+ - None
+
+ Tools
+ -----
+ - None
+
+ Fortran API
+ -------
+ - SIZEOF Replaced by C_SIZEOF and STORAGE_SIZE.
+
+ The intrinsic function SIZEOF is non-standard and should be replaced with a
+ standard intrinsic function.
+
+ If the F2008 intrinsic C_SIZEOF and STORAGE_SIZE are available, then they will
+ be used instead of the non-standard SIZEOF intrinsic, even when the SIZEOF
+ function is available.
+
+ (MSB - 2014/6/16, HDFFV-8653)
+
+ - Non-functional API: h5pget_fill_value_f
+
+ The Fortran wrapper h5pget_fill_value_f was calling the wrong C API.
+
+ The correct C API, H5Pget_fill_value, is now called by the Fortran
+ wrapper.
+
+ (MSB - 2014/9/25, HDFFV-8879)
+
+ - Interoperability with C HDF5: H5Literate and h5literate_f
+
+ h5literate_f assumes the return value for the callback function to
+ be of type int (or int_f in C). However, in the C wrapper the return
+ value of H5Literate is type herr_t, and this could cause
+ interoperability issues.
+
+ The callback function should be declared INTEGER(C_INT) for
+ portability. The tests were updated accordingly.
+
+ (MSB - 2014/9/26, HDFFV-8909)
+
+ - Interoperability with C HDF5: Constant INTEGER Parameters with the
+ H5FD Interface
+
+ Wrong type cast of constant Fortran INTEGER parameters was used.
+
+ The following parameter constant types were changed from INTEGER to
+ INTEGER(HID_T) to match the C types: H5FD_CORE, H5FD_FAMILY, H5FD_LOG,
+ H5FD_MPIO, H5FD_MULTI, H5FD_SEC2, and H5FD_STDIO.
+
+ Other internal 'int' types where changed to 'hid_t'; these are
+ transparent to the user.
+
+ (MSB - 2014/7/18, HDFFV-8748)
+
+ C++ API
+ ------
+ - Memory Leaks
+
+ There were several potential memory leaks in the library due to
+ dynamically allocated strings not being freed when failure occurs.
+
+ Applied user's patches to remove these potential memory leaks.
+
+ (BMR - 2014/09/30, HDFFV-8928)
+
+ - Disallow H5F_ACC_CREAT
+
+ H5F_ACC_CREAT was included in the C++ API but the C library does not
+ allow it at this time.
+
+ Removed this flag from the functions in H5File class.
+
+ (BMR - 2014/09/29, HDFFV-8852)
+
+ - Missing Flags in Documentation: H5F_ACC_RDONLY and H5F_ACC_RDWR
+
+ The H5F_ACC_RDONLY and H5F_ACC_RDWR flags were missing from the
+ documentation of the H5File constructors.
+
+ These two flags are now included in the documentation for opening
+ files.
+
+ (BMR - 2014/09/29, HDFFV-8852)
+
+ High-level APIs:
+ ------
+ - Seg Faults in H5TBread_field_name and H5TBread_field_name_f
+
+ When H5TBread_field_name or H5TBread_field_name_f were used to read a
+ field and if the name of the field was wrong, a segmentation fault
+ would result.
+
+ Both C and Fortran APIs were fixed so they no longer seg fault if
+ the name of the field is wrong, and both APIs return a negative
+ value if the name of the field is wrong.
+
+ (MSB - 2014/09/29, HDFFV-8912)
+
+ - Possible Buffer Overflow in High-level (HL) APIs
+
+ Multiple HL APIs (H5DSis_scale is one example) had issues:
+ (1) The datatype from the file was re-used as the memory datatype,
+ and
+ (2) No effort was made to ensure that strings were actually
+ null-terminated.
+
+ All of the HL routines now check for NULL pointers, for null-terminated
+ strings, and to see if string buffers are short enough not to overflow
+ the buffer. The minimum length of the buffers is now used in strncmp
+ to avoid overflow.
+
+ (MSB - 2014/9/29, HDFFV-8670)
+
+ - Behavior Change of H5LTdtype_to_text
+
+ If a user buffer was passed in to H5LTdtype_to_text along with the
+ length, then the function would not truncate at the end of the
+ buffer, but would exceed the end of the user buffer.
+
+ H5LTdtype_to_text was changed to truncate the string if the user
+ buffer is too small.
+
+ (MSB - 2014/9/29, HDFFV-8855)
+
+ Fortran High-level APIs:
+ ------
+ - See entry for HDFFV-8912 above.
+
+ Testing
+ -------
+ - A subtest in parallel h5diff (ph5diff) testing was bypassed for the
+ local Linux 32 machine due to unknown issue in the previous version of
+ Mpich. The failure no long exists in the current Mpich. Therefore the
+ bypass is removed. (AKC - 2014/11/03 HDFFV-8954)
+
+ - Fixed incorrect exit code values (was -1) in testframe which is commonly
+ used by several test programs. (AKC - 2014/07/22 HDFFV-8881)
+
+ - Fixed Incorrect Exit Code Values in Testframe
+ The testframe which is commonly used by several test programs
+ had some incorrect exit code values. Fixed the incorrect exit code
+ values. (AKC - 2014/07/22, HDFFV-8881)

+Known Problems
+==============
+* On cygwin platforms the feature to load dynamic filter libraries only looks
+ for libraries with the a so extension. Support for cygwin cygxxx.dll libraries
+ is planned for the next release.
+ (ADB - 2014/11/04 - HDFFV-8736)
+
+* On windows platforms in debug configurations, the VFD flush1 tests will fail
+ with the split and multi VFD drivers. These tests will display a modal debug
+ dialog which must be answered or wait for the test timeout to expire.
+ The flush1 and flush2 tests will be skipped under debug for this release.
+ (ADB - 2014/06/23 - HDFFV-8851)
+
+* 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 (Issue 8147). Since the algorithm is trying to detect the alignment
+ of integers, ideally the flag -fcatch-undefined-behavior shouldn't 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)
+
+* 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)
+
+* The h5dump and h5diff utilities occasionally produce different output
+ between Linux and Windows systems. This is caused by lower-level library
+ routines that fail to write fill values to the user's buffer when reading
+ unallocated chunks from datasets that have a fill value set to
+ H5D_FILL_VALUE_DEFAULT. Due to platform differences the return of
+ spurious data values has only been encountered on Windows 32-bit systems.
+ (Issue HDFFV-8247; JP - 2013/03/27)
+
+* 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 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)
+
+* 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)
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+ (SLU - 2005/06/30)

+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - Autotools: Automake updated to 1.14.1 (ADB - 2014/04/08)
+
+ - CMake: Moved minimum CMake version to 2.8.11 which enables better library
+ include processing. (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. (MSB - 2014/1/2014)
+
+ C++ API
+ -------
+ - The following new features are added:
+ + Wrappers to class H5Object to get an object's name (HDFFV-8548).
+ ssize_t getObjName(char *obj_name, size_t buf_size = 0)
+ ssize_t getObjName(H5std_string& obj_name, size_t len = 0)
+ H5std_string getObjName()
+ + Wrappers to class H5CommonFG to get a child object's type from a
+ group or file (HDFFV-8367).
+ H5O_type_t childObjType(const H5std_string& objname)
+ H5O_type_t childObjType(const char* objname)
+ H5O_type_t childObjType(hsize_t index,
+ H5_index_t index_type=H5_INDEX_NAME,
+ H5_iter_order_t order=H5_ITER_INC, const char* objname=".")
+ + Wrappers to class DSetMemXferPropList for setting/getting a transform
+ property list (HDFFV-7907).
+ DSetMemXferPropList(const char* expression);
+ void setDataTransform(const char* expression)
+ void setDataTransform(const H5std_string& expression)
+ ssize_t getDataTransform(char* exp, size_t buf_size=0)
+ H5std_string getDataTransform()
+ + Wrapper to CompType for setting size to compound datatype (HDFFV-8642).
+ void setSize(size_t size)
+ + Overloaded functions to provide prototypes that declare constant
+ arguments const (HDFFV-3384). These include:
+ DataSet::fillMemBuf
+ DataSet::getVlenBufSize
+ DataSpace::extentCopy
+ DataType::commit
+ FileAccPropList::setSplit
+ H5File::getVFDHandle
+ + Additional overload to class H5Location to get a comment as a char*
+ ssize_t getComment(const char* name, size_t buf_size, char* comment)
+ + Additional overloads to class Attribute to get an attribute's name for
+ convenience:
+ ssize_t getName(char* attr_name, size_t buf_size=0)
+ ssize_t getName(H5std_string& attr_name, size_t buf_size=0)
+ (BMR, 2014/04/15)
+ + A static wrapper to Exception for printing the error stack without an
+ instance of Exception
+ static void printErrorStack(FILE* stream = stderr,
+ hid_t err_stack = H5E_DEFAULT);
+ (BMR, 2014/04/25)
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ Mac OS X 10.6 Snow Leopard is not supported by Apple any more. In view of
+ the added support of Mac OS X 10.9, Mac OS X 10.6 is retired from HDF5
+ supported platforms. (AKC - 2014/03/14 HDFFV-8704)
+
+ Mac OS X 10.9 Mavericks is supported. (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. (DER - 2014/04/11)

+
+Known Problems
+==============
+* When reading or writing a dataset (H5Dread/H5Dwrite) with a large selection
+ size (e.g., 2GB ~= 500 million of 4 bytes integers or floating point
+ numbers), some I/O systems may not be able to process it correctly.
+ We advise users to find out system limits before using large selections. If
+ I/O size limits exist, application should use HDF5 partial I/O capabilities
+ (e.g., H5Sselect_hyperslab(...)) to divide large requests into smaller sizes.
+ In this case we also advise users not to use chunk storage sizes larger that
+ 2GB since the HDF5 library performs I/O on the entire chunk. We will work
+ on the HDF5 library to divide large data requests to smaller I/O requests.
+ (AKC 2014/05/02 HDFFV-8479)
+
+* Due to an Intel compiler bug introduced in version 14.0.1, the HDF5 FORTRAN
+ wrappers do not work with configure option --enable-fortran2003.
+ However, the option --enable-fortran works with Intel 14.0.1. The compiler
+ bug was fixed in Intel version 14.0.2 and resolved the issue.
+ (MSB - 2014/4/15)
+
+* Due to a PGI compiler bug introduced in versions before 13.3 and versions
+ after 14.2, the FORTRAN test 'Testing get file image' will fail.
+ (MSB - 2014/4/15)
+
+* On CYGWIN, when building the library dynamically, testing will fail on
+ dynamically loaded filters. The test process will build dynamic filter
+ libraries with the *.dll.a extension, and the HDF5 Library will be looking
+ for *.so libraries. Entered as issue HDFFV-8736. (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. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.

+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - Added a configuration option to change the default plugin path.
+ The configure option is --with-default-plugindir=location.
+ The cmake option is -DH5_DEFAULT_PLUGINDIR:PATH=location.
+ HDFFV-8513. (ADB 2013/09/04)
+ - Renamed FFLAGS to FCFLAGS in configure. (ADB 2013/08/13)
+ - CMake can now package a compressed examples file, the default for
+ Windows binaries from HDF Group. (ADB - 2013/07/22)
+
+ Library
+ -------
+ - None
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5repack: Added the ability to use plugin filters to read and write
+ files. The option uses the filter number. HDFFV-8345
+ (ADB - 2013/09/04).
+ - h5dump: Added the option -N --any_path, which searches the file for
+ paths that match the search path. HDFFV-7989 (ADB - 2013/08/12).
+ - h5dump: Added the optional arg 0 to -A, which excludes attributes
+ from display. HDFFV-8134 (ADB - 2013/08/01).
+
+ High-Level APIs
+ ---------------
+ - None
+
+ Fortran API
+ -----------
+ - None
+
+ C++ API
+ -------
+ - Added tutorial examples to C++/examples. They can be installed by
+ "make install-examples" and, in the installed directory, they can be
+ executed by running the script file run-c++-ex.sh. (BMR - 2013/09/28)
+ - A new class, H5::H5Location, is added to represent the location concept
+ in the C library. It is a base class to H5::H5File and H5::H5Ojbect,
+ whose member functions are moved into H5::H5Location. H5::H5File can
+ now inherent those functions. As a result, an H5::H5File object can have
+ an attribute. (BMR - 2013/09/27)
+ - Added wrappers for H5Rget_obj_type2 to retrieve the type of the object
+ that an object reference points to. (BMR - 2013/09/27)
+ H5O_type_t H5Location::getRefObjType(void *ref, H5R_type_t ref_type)
+ - Added wrappers for H5Aexist to check whether an attribute exists given

+
+Bug Fixes since HDF5-1.8.11
+===========================
+
+ Configuration
+ -------------
+ - Modified H5detect.c to scan floating point types for padding bits before
+ analyzing the type further. This should fix problems with gcc 4.8.
+ (NAF - 2013/09/19 - HDFFV-8523/HDFFV-8500)
+ - HDF5 rpaths are no longer encoded in the library files when configured
+ with --disable-sharedlib-rpath. (LRK-2013-09-23 - HDFFV-8276)
+
+ Library
+ -------
+ - Added const qualifier to source buffer parameters in H5Dgather and
+ H5D_scatter_func_t (H5Dscatter callback). (NAF - 2013/7/09)
+
+ - CMake now creates *.so.{lt_version} files with the same version as
+ configure. (ADB - 2013/06/05 HDFFV-8437)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Performance
+ -------------
+ - None
+
+ Tools
+ -----
+ - h5dump: Added the option -N --any_path, which searches the file for
+ paths that match the search path. HDFFV-7989 (ADB - 2013/08/12).
+ - h5dump: Added the optional arg 0 to -A, which excludes attributes
+ from display. HDFFV-8134 (ADB - 2013/08/01).
+ - h5dump correctly exports subsetted data to a file, using the --output
+ option. (ADB - 2013/06/07 HDFFV-8447)
+ - h5cc and other compile scripts now default to linking shared libraries
+ when HDF5 is configured with the --disable-static option.
+ (LRK - 2013-09-23 - HDFFV-8141)
+
+ F90 API
+ -------
+ - None
+
+ C++ API
+ ------
+ - None
+
+ High-Level APIs:
+ ------
+ - None
+
+ Fortran High-Level APIs:
+ ------
+ - None
+
+ Testing
+ -------
+ - test/big sometimes failed with the message of "file selection+offset not
+ within extent". This has been fixed. (AKC - 2013/09/28 HDFFV-8271).
+ - tools/h5diff/testh5diff.sh is run in every "make check", even after it
+ has passed in the previous run. It should not run again if there are no
+ code changes. Fixed. (AKC - 2013/07/19 HDFFV-8392)

+Known Problems
+==============
+* Several HDF5 command-line tools and tests leave behind generated files
+ that are not cleaned up with "make clean" or "make distclean" when software
+ is built in place. The issue will be addressed in the 1.8.13 release. We
+ recommend to use build directory to compile and test HDF5 as described
+ in the INSTALL file, section 4.2.
+
+* Source directory names with spaces in them will cause failures in configure
+ or make on Mac (HDFFV-8152), Linux, and probably all other platforms. If a
+ configure command with a space is run from a build directory, it will exit
+ with an error message: "checking whether build environment is sane...
+ configure: error: unsafe srcdir value: '/scr/lrknox/hdf5 v1.8.12'". If
+ configure is run inside or below the directory with the space in the name,
+ libtool will get the directory path from the system, put the part of the
+ path before the space in the libdir variable in .../src/libhdf5.la, and
+ then fail to find the nonexistent directory. This is a known libtool issue
+ and the suggested workaround is to rename the directory without spaces.
+ (LRK - 2013/10/22)
+
+* 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 (HDFFV-8147). This issue will be addressed in the
+ next release. (SLU - 2013/10/16)
+
+* Running make check for the tools can fail in the tools tests if make was not
+ run prior. The tests for the tools use other tools in the tests, therefore
+ all the tools should be built before testing the tools. (ADB - 2013/10/09)
+
+* Make provided by Solaris fails in "make check". Solaris users should use
+ gmake to build and install 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 h5dump and h5diff utilities occasionally produce different output
+ between Linux and Windows systems. This is caused by lower-level library
+ routines that fail to write fill values to the user's buffer when reading
+ unallocated chunks from datasets that have a fill value set to
+ H5D_FILL_VALUE_DEFAULT. Due to platform differences the return of
+ spurious data values has only been encountered on Windows 32-bit systems.
+ (Issue HDFFV-8247; JP - 2013/03/27)
+
+* 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 is 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 kernel
+ (3.2.2 on Fedora) do not 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. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as

+
+New Features
+============
+
+ Configuration
+ -------------
+ - Libtool version number is changed to 8.0.0 because there are API
+ changes. See below for details. (AKC - 2013/05/07 HDFFV-8435)
+ - Mac OS X 10.7 (Lion) and 10.8 (Mountain Lion) uses clang/clang++ as the
+ default C and C++ compilers. (AKC - 2013/04/19 HDFFV-8245)
+ - CMake minimum is now 2.8.10. (ADB 2013/1/14)
+ - A new tool, cmakehdf5, which is a build command script similar to
+ buildhdf5 is added and is available in the bin directory.
+ (AKC - 2013/01/16 HDFFV-8336)
+
+ Library
+ -------
+ - The library can load filter libraries dynamically during runtime. Users
+ can set the search path through environment variable HDF5_PLUGIN_PATH
+ and call H5Pset_filter to enable a dynamic filter. (SLU - 2013/04/08)
+ - Added new API functions H5Dscatter and H5Dgather to scatter data to and
+ and gather data from a selection within a memory buffer.
+ (NAF - 2013/02/05)
+ - The library now supports the data conversion from enumeration to numeric
+ (integer and floating-point number) datatypes. See Issue HDFFV-8221.
+ (SLU - 2012/10/23)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5dump: added new option -O or -ddl to output the ddl text to a file. This
+ is a complement to the -o or --output option, which redirects the data to
+ a file. HDFFV-8229 (ADB - 2013/2/25)
+
+ High-Level APIs
+ ---------------
+ - A new API function, H5DOwrite_chunk. This function writes a data chunk
+ directly into a file, bypassing hyperslab selection, data conversion,
+ and the filter pipeline. The user must be careful with the function and
+ clearly understand the I/O process of the library. (SLU - 2013/2/11)
+
+ Fortran API
+ -----------
+ - New API functions added (MSB - 2013/3/23):
+
+ h5odecr_refcount_f, h5oexists_by_name_f, h5oget_comment_f,
+ h5oget_comment_by_name_f, h5oincr_refcount_f, h5oopen_by_idx_f,
+ h5oset_comment_f, h5oset_comment_by_name_f, h5oset_comment_by_name_f
+
+ F2003: h5oget_info_f, h5oget_info_by_idx_f, h5ovisit_by_name_f
+
+
+ C++ API
+ -------
+ - None
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - SunOS 5.11 (emu) 32-bit and 64-bit with Sun C/C++ 5.12 compiler and
+ Sun Fortran 95 8.6 compiler.
+ - Visual Studio 2012 w/ Intel Fortran 13 on Windows 7
+ - g95 released new version recently and is tested in this release.
+
+Bug Fixes since HDF5-1.8.10
+==========================
+
+ Configuration
+ -------------
+ - Fixed Thread-safe configure failure for the AIX platform.
+ (AKC - 2013/04/19 HDFFV-8390)
+ - Configure will check the result of header searches before searching for
+ the library.
+ Fixes HDFFV-8257 (ADB 2013/03/04)
+ - HDF does not support building SHARED Fortran libraries on OSX. Added
+ CMake code to check for this condition.
+ Fixes HDFFV-8227 (ADB 2013/03/04)
+ - CMake builds on Windows will no longer use legacy naming for libraries.
+ The "dll" tag will no longer be added to the name of *.lib and *.dll.
+ The option HDF_LEGACY_NAMING is now OFF by default.
+ Fixes HDFFV-8292 (ADB 2013/01/30)
+
+ Library
+ -------
+ - The library now behaves correctly when performing large I/O operations
+ on Mac OS-X. Previously, single I/O operations > 2 GB would fail
+ since the Darwin read/write calls cannot handle the number of bytes
+ that their parameter types imply.
+ Fixes HDFFV-7975 and HDFFV-8240 (DER 2013/01/07)
+ - Fixed a bug in the core VFD that causes failures when opening files
+ > 2 GB.
+ Fixes HDFFV-8124 and HDFFV-8158 (DER 2013/01/07)
+ - Fixed a bug where unintialized memory was read during variable-length
+ type conversion. This caused segfaults in netCDF. Fixes HDFFV-8159.
+ (DER 2013/03/30)
+ - Removed the H5Pset/get_dxpl_multi functions from the library. The
+ intended functionality for them was never fully implemented, and they
+ have always been fundamentally broken. NOTE: This does not affect
+ setting the multi VFD or any expected VFD functionality. Multi VFD
+ usage remains unchanged.
+ Fixes HDFFV-8296. (DER 2013/03/30)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Performance
+ -------------
+ - None
+
+ Tools
+ -----
+ - h5redeploy is changed to do this by default:
+ Installation directories:
+ prefix architecture-independent files.
+ exec_prefix architecture-dependent files, default is <prefix>.
+ libdir libraries, default is <exec_prefix>/lib.
+ includedir header files, default is <prefix/include>.
+ This allows users to just change the first line of prefix=<...> and the
+ effect will change libdir and includedir too. (AKC 2013/04/05 HDFFV-8358)
+ - h5repack: Fixed failure to convert the layout of a small chunked
+ dataset (size < 1K) to contiguous layout. HDFFV-8214 (JKM 2013/03/26)
+ - h5dump: Fixed displaying compression ratio for unknown or user-defined
+ filters. HDFFV-8344 (XCAO 2013/03/19)
+ - h5dump: Changed UNKNOWN_FILTER to USER_DEFINED_FILTER for user defined
+ filter. HDFFV-8346 (XCAO 2013/03/19)
+ - h5diff: Fixed to return the correct exit code 1 when the program
+ detects a unique extra attribute. Prior to this fix, h5diff returned
+ exit code 0 indicating the two files are identical.
+ HDFFV-7643 (JKM 2013/02/15)
+ - h5dump: Fixed writing nulls to a binary file when exporting a dataset
+ with compound string datatype. HDFFV-8169 (ADB 2013/1/31)
+ - The following h5stat test case failed in BG/P machines (and potentially
+ other machines that display extra output if an MPI task returns with a
+ non-zero code.)
+ Testing h5stat notexist.h5
+ The test script was fixed to ignore the extra output. HDFFV-8233
+ (AKC - 2012/11/30)
+ - h5diff: Improved speed when comparing HDF5 files with lots of
+ attributes. Much slower performance was identified with release versions
+ from 1.8.7 to 1.8.10 compared to 1.8.6. (JKM 2012/10/19)
+
+ F90 API
+ -------
+ - The integer type of the 'offset' argument in h5pset_external_f and
+ h5pget_external_f was changed to INTEGER(KIND=OFF_T) to support 8-byte
+ integers, matching the C type definition of off_t. (MSB - 2013/3/23)
+ - h5fc updated to recognize .f95, .f03 and .f08 file extensions.
+
+ C++ API
+ ------
+ - The C++ wrappers DSetMemXferPropList::setMulti/getMulti were removed
+ because the C functions H5Pset/get_dxpl_multi functions are removed
+ from the library. Fixes HDFFV-8296 by DER. (BMR 2013/03/30)
+ - An exception thrown by an internal function was not propagating to the
+ test program during stack unwinding, so it couldn't be caught by the
+ test, and the program terminated "without an active exception." It
+ seemed that the problem happened when c_str() was used to generate
+ an equivalent const char* from a std::string and the resulting string
+ was passed to the internal function. As a work-around, we added a
+ try/catch around the the call to the internal function and when the
+ exception is caught there, it is re-thrown. Fixes HDFFV-8067.
+ (BMR 2013/03/30)
+
+ High-Level APIs:
+ ------
+ - Fixed a problem with H5DSget_scale_name including the NULL terminator
+ in the size calculation returned by the function. The API was changed
+ to NOT include the NULL terminator in the size of name returned
+ (MSB- 2013/2/10)
+
+ Fortran High-Level APIs:
+ ------
+ - None
+
+ Testing
+ -------
+ - In some Mac systems, testlibinfo.sh failed with this error:
+ Check file ../src/.libs/libhdf5.7.dylib
+ strings: object: ../src/.libs/libhdf5.7.dylib malformed object \
+ (unknown load command 15)
+ The strings command of Mac systems inspects library files, and older
+ versions of strings may not know newer library formats, resulting
+ in errors. Fixed by sending the library file as stdin to the strings
+ command to avoid this problem. (AKC - 2013/03/08 HDFFV-8305)
+ - Fixed a typo in the ERROR macro in test/testhdf5.h. It segmentation
+ faulted when used before. (AKC - 2013/02/12 HDFFV-8267)

+
+Known Problems
+==============
+
+* 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 h5dump and h5diff utilities occasionally produce different output
+ between Linux and Windows systems. This is caused by lower-level library
+ routines that fail to write fill values to the user's buffer when reading
+ unallocated chunks from datasets that have a fill value set to
+ H5D_FILL_VALUE_DEFAULT. Due to platform differences the return of
+ spurious data values has only been encountered on Windows 32-bit systems.
+ (Issue HDFFV-8247; JP - 2013/03/27)
+
+* 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)
+
+* The library's test dt_arith.c showed a compiler's rounding problem on
+ Cygwin when converting from unsigned long long to long double. The
+ library's own conversion works fine. We defined a macro for Cygwin to
+ skip this test until we can solve the problem.
+ (SLU - 2010/05/05 - HDFFV-1264)
+
+* 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. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.

+
+New Features
+============
+
+ Configuration
+ -------------
+ - A new tool, cmakehdf5, which is a build command script similar to
+ buildhdf5 is added and is available in the bin directory.
+ (AKC - 2013/01/21)
+
+ Library
+ -------
+ - Updated to latest autotools and changed all hard *.sh scripts to
+ configure managed *.sh.in files. Removed overloading of autotools
+ TESTS variable by examples and tests. Renamed configure.in to
+ configure.ac. (ADB - 2012/08/23 - HDFFV-8129)
+ - The data sieve buffer size was set for all the datasets in the file. It
+ could waste memory if any dataset size is smaller than the sieve buffer
+ size. Now the library picks the smaller one between the dataset size
+ and the sieve buffer size from the file access property. See Issue 7934.
+ (SLU - 2012/4/11)
+
+ Parallel Library
+ ----------------
+ - Added the H5Pget_mpio_no_collective_cause() function that retrieves
+ reasons why the collective I/O was broken during read/write IO access.
+ (JKM - 2012/08/30 HDFFV-8143)
+
+ - Added H5Pget_mpio_actual_io_mode_f (MSB - 2012/09/27)
+
+ Tools
+ -----
+ - h5import: Changed to allow the use of h5dump output as input files to
+ h5import. h5dump must include the "-p" option to print the properties;
+ configuration file is captured output of h5dump. The restrictions are
+ that only one dataset with a simple datatype (integer, floating-point,
+ or string) can be processed. Integers and floating-point imports from
+ h5dump must use the "binary" option for the data file. The string version
+ uses the h5dump "-y --width=1" options to disable the indexing printouts,
+ print single columns, and obviously NOT use the "binary" option.
+ (ADB - 2012/07/19 HDFFV-721)
+
+ High-Level APIs
+ ---------------
+ - None
+
+ Fortran API
+ -----------
+ - Fixed a typo in return value of the nh5dread_f_c function (was 1
+ instead of 0 on success); fixed the return value to make it consistent
+ with other Fortran functions; cleaned debug statements from the code.
+ (EIP - 2012/06/23)
+
+ C++ API
+ -------
+ - None
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - None
+
+Bug Fixes since HDF5-1.8.10
+===========================
+ Library
+ -------
+ - The library now behaves correctly when performing large I/O operations on
+ Mac OS-X. Previously, single I/O operations > 2 GB would fail since the
+ Darwin read/write calls cannot handle the number of bytes that their
+ parameter types imply.
+ Fixes HDFFV-7975 and HDFFV-8240 (DER - 07 JAN 2013)
+ - Fixed a bug in the core VFD that cause failures when opening files > 2 GB.
+ Fixes HDFFV-8124 and HDFFV-8158 (DER - 07 JAN 2013)
+
+ Tools
+ -----
+ - The following h5stat test case failed in BG/P machines (and potentially
+ other machines that display extra output if an MPI task returns with a
+ non-zero code.)
+ Testing h5stat notexist.h5
+ The test script was fixed to ignore the extra output.
+ HDFFV-8233 (AKC - 2012/12/17)
+ - h5diff: Fixed slowness when comparing HDF5 files with many attributes.
+ Much slower performance was identified with later release version
+ (from 1.8.7 to 1.8.10) compared to 1.8.6. The issue was introduced
+ from fixing an attribute related bug for 1.8.7 release in the past.
+ HDFFV-8145 (JKM 2012/12/13)
+
+ Testing
+ -------
+ - None
+
+Bug Fixes since HDF5-1.8.9
+==========================
+
+ Configuration
+ -------------
+ - Fixed configure --enable-production to not use -O optimization for Lion
+ and Mountain Lion systems when gcc (i686-apple-darwin11-llvm-gcc-4.2
+ (GCC) 4.2.1) is used. Somehow the -O optimization will cause some of
+ the hard conversion code in test/dt_arith.c to fail. HDFFV-8017.
+ (AKC - 2012/10/10)
+ - Fixed AIX Fortran compiler flags to use appropriate settings for
+ debugging, profiling, and optimization situations. HDFFV-8069.
+ (AKC 2012/09/27)
+
+ Library
+ -------
+ - Fixed a memory leak exposed when inserting/removing a property
+ from a property list several times. HDFFV-8022. (MSC 2012/05/18)
+ - The file_image test will fail in the "initial file image and callbacks in
+ the core VFD" sub-test if the source directory is read-only as the test
+ fails to create its test files in the build directory. This has been
+ fixed. HDFFV-8009 (AKC - 2012/07/06)
+
+
+ Parallel Library
+ ----------------
+ - The MPI-POSIX VFD was updated to include the POSIX and Windows
+ correctness features added that had already been added to the other VFDs.
+ HDFFV-8058/7845. (DER 2012/09/17)
+
+ Performance
+ -------------
+ - Removed program perform/benchpar from the enable-build-all list. The
+ program will be retired or moved to another location. HDFFV-8156
+ (AKC 2012/10/01)
+ - Retired program perform/mpi-perf. Its purpose has been incorporated
+ into h5perf. (AKC 2012/09/21)
+
+ Tools
+ -----
+ - h5repack: "h5repack -f NONE file1.h5 out.h5" command failed if
+ source file contains chunked dataset and a chunk dim is bigger than
+ the dataset dim. Another issue is that the command changed max dims
+ if chunk dim is smaller than the dataset dim. These issue occurred
+ when dataset size is smaller than 64k (compact size limit) Fixed both.
+ HDFFV-8012 (JKM 2012/09/24)
+ - h5diff: Fixed the counter in verbose mode (-v, -r) so that it will no
+ longer add together the differences between datasets and the differences
+ between attributes of those datasets. This change makes the output of
+ verbose mode consistent for datasets, groups, and committed datatypes.
+ HDFFV-5919 (JKM 2012/09/10)
+ - h5diff: Fixed the incorrect result when comparing attribute data
+ values and the data type has the same class but different sizes.
+ HDFFV-7942 (JKM 2012/08/15)
+ - h5dump: Replaced single element fwrite with block writes.
+ HDFFV-1208 (ADB 2012/08/13)
+ - h5diff: Fixed test failure for "make check" due to failure of
+ copying test files when performed in HDF5 source tree. Also applied
+ to other tools. HDFFV-8107 (JKM 2012/08/01)
+ - ph5diff: Fixed intermittent hang issue on a certain operation in
+ parallel mode. It was detected by daily test for comparing
+ non-comparable objects, but it could have occurred in other
+ operations depending on machine condition. HDFFV-8003 (JKM 2012/08/01)
+ - h5diff: Fixed the function COPY_TESTFILES_TO_TESTDIR() of testh5diff.sh
+ to better report when there is an error in the file copying.
+ HDFFV-8105 (AKC 2012/07/22)
+ - h5dump: Fixed the sort by name display to maintain correct parent/child
+ relationships between ascending/descending order.
+ HDFFV-8095 (ADB 2012/07/12)
+ - h5dump: Fixed the display by creation order when using option -n
+ (print contents).
+ HDFFV-5942 (ADB 2012/07/09)
+ - h5dump: Changed to allow H5T_CSET_UTF8 to be displayed in h5dump output.
+ Used technique similar to what was done in h5ls (matches library
+ options).
+ HDFFV-7999 (ADB 2012/05/23)
+ - h5diff: Fixed the tool so that it will not check and display the status
+ of dangling links without setting the --follow-symlinks option. This
+ also improved performance when comparing lots of external links without
+ the --follow-symlinks option.
+ HDFFV-7998 (JKM 2012/04/26)
+
+ F90 API
+ -------
+
+ - Fixed a typo in return value of the nh5dread_f_c function (was 1
+ instead of 0 on success); fixed the return value to make it consistent
+ with other Fortran functions; cleaned debug statements from the code.
+ (EIP - 2012/06/23)
+
+ - Fixed a problem writing/reading control characters to a dataset; writing
+ a string containing alerts, backspace, carriage_return, form_feed,
+ horizontal_tab, vertical_tab, or new_line is now tested and working.
+ (MSB - 2012/09/01)
+
+ - Corrected the integer type of H5S_UNLIMITED_F to HSIZE_T (MSB - 2012/09/01)
+
+ - Corrected the number of continuation lines in the src files
+ to be less than 32 lines for F95 compliance. (MSB - 2012/10/01)
+
+ C++ API
+ ------
+ - None
+
+ High-Level APIs:
+ ------
+
+ - Fixed problem with H5TBdelete_record destroying all data following the
+ deletion of a row. (MSB- 2012/7/26)
+
+ - Fixed H5LTget_attribute_string not closing an object identifier when an
+ error occurs. (MSB- 2012/7/21)
+
+ - Corrected the return type of H5TBAget_fill from herr_t to htri_t to
+ reflect that a return value of 1 indicates that a fill value is
+ present, 0 indicates a fill value is not present, and <0 indicates an
+ error.
+
+ Fortran High-Level APIs:
+ ------
+ - None

+
+Known Problems
+==============
+* 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 kernal) 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)
+
+* 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)
+
+* The library's test dt_arith.c showed a compiler's rounding problem on
+ Cygwin when converting from unsigned long long to long double. The
+ library's own conversion works fine. We defined a macro for Cygwin to
+ skip this test until we can solve the problem.
+ (SLU - 2010/05/05 - HDFFV-1264)
+
+* 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. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.

+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - None
+
+ Library
+ -------
+ - Updated to latest autotools and changed all hard *.sh scripts to
+ configure managed *.sh.in files. Removed overloading of autotools
+ TESTS variable by examples and tests. Renamed configure.in to
+ configure.ac. (ADB - 2012/08/23 - HDFFV-8129)
+ - The data sieve buffer size was set for all the datasets in the file. It
+ could waste memory if any dataset size is smaller than the sieve buffer
+ size. Now the library picks the smaller one between the dataset size
+ and the sieve buffer size from the file access property. See Issue 7934.
+ (SLU - 2012/4/11)
+
+ Parallel Library
+ ----------------
+ - Added the H5Pget_mpio_no_collective_cause() function that retrieves
+ reasons why the collective I/O was broken during read/write IO access.
+ (JKM - 2012/08/30 HDFFV-8143)
+
+ - Added H5Pget_mpio_actual_io_mode_f (MSB - 2012/09/27)
+
+ Tools
+ -----
+ - h5import: Changed to allow the use of h5dump output as input files to
+ h5import. h5dump must include the "-p" option to print the properties;
+ configuration file is captured output of h5dump. The restrictions are
+ that only one dataset with a simple datatype (integer, floating-point,
+ or string) can be processed. Integers and floating-point imports from
+ h5dump must use the "binary" option for the data file. The string version
+ uses the h5dump "-y --width=1" options to disable the indexing printouts,
+ print single columns, and obviously NOT use the "binary" option.
+ (ADB - 2012/07/19 HDFFV-721)
+
+ High-Level APIs
+ ---------------
+ - None
+
+ Fortran API
+ -----------
+ - Fixed a typo in return value of the nh5dread_f_c function (was 1
+ instead of 0 on success); fixed the return value to make it consistent
+ with other Fortran functions; cleaned debug statements from the code.
+ (EIP - 2012/06/23)
+
+ C++ API
+ -------
+ - None
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - None
+
+Bug Fixes since HDF5-1.8.9
+==========================
+
+ Configuration
+ -------------
+ - Fixed configure --enable-production to not use -O optimization for Lion
+ and Mountain Lion systems when gcc (i686-apple-darwin11-llvm-gcc-4.2
+ (GCC) 4.2.1) is used. Somehow the -O optimization will cause some of
+ the hard conversion code in test/dt_arith.c to fail. HDFFV-8017.
+ (AKC - 2012/10/10)
+ - Fixed AIX Fortran compiler flags to use appropriate settings for
+ debugging, profiling, and optimization situations. HDFFV-8069.
+ (AKC 2012/09/27)
+
+ Library
+ -------
+ - Fixed a memory leak exposed when inserting/removing a property
+ from a property list several times. HDFFV-8022. (MSC 2012/05/18)
+ - The file_image test will fail in the "initial file image and callbacks in
+ the core VFD" sub-test if the source directory is read-only as the test
+ fails to create its test files in the build directory. This has been
+ fixed. HDFFV-8009 (AKC - 2012/07/06)
+
+
+ Parallel Library
+ ----------------
+ - The MPI-POSIX VFD was updated to include the POSIX and Windows
+ correctness features added that had already been added to the other VFDs.
+ HDFFV-8058/7845. (DER 2012/09/17)
+
+ Performance
+ -------------
+ - Removed program perform/benchpar from the enable-build-all list. The
+ program will be retired or moved to another location. HDFFV-8156
+ (AKC 2012/10/01)
+ - Retired program perform/mpi-perf. Its purpose has been incorporated
+ into h5perf. (AKC 2012/09/21)
+
+ Tools
+ -----
+ - h5repack: "h5repack -f NONE file1.h5 out.h5" command failed if
+ source file contains chunked dataset and a chunk dim is bigger than
+ the dataset dim. Another issue is that the command changed max dims
+ if chunk dim is smaller than the dataset dim. These issue occurred
+ when dataset size is smaller than 64k (compact size limit) Fixed both.
+ HDFFV-8012 (JKM 2012/09/24)
+ - h5diff: Fixed the counter in verbose mode (-v, -r) so that it will no
+ longer add together the differences between datasets and the differences
+ between attributes of those datasets. This change makes the output of
+ verbose mode consistent for datasets, groups, and committed datatypes.
+ HDFFV-5919 (JKM 2012/09/10)
+ - h5diff: Fixed the incorrect result when comparing attribute data
+ values and the data type has the same class but different sizes.
+ HDFFV-7942 (JKM 2012/08/15)
+ - h5dump: Replaced single element fwrite with block writes.
+ HDFFV-1208 (ADB 2012/08/13)
+ - h5diff: Fixed test failure for "make check" due to failure of
+ copying test files when performed in HDF5 source tree. Also applied
+ to other tools. HDFFV-8107 (JKM 2012/08/01)
+ - ph5diff: Fixed intermittent hang issue on a certain operation in
+ parallel mode. It was detected by daily test for comparing
+ non-comparable objects, but it could have occurred in other
+ operations depending on machine condition. HDFFV-8003 (JKM 2012/08/01)
+ - h5diff: Fixed the function COPY_TESTFILES_TO_TESTDIR() of testh5diff.sh
+ to better report when there is an error in the file copying.
+ HDFFV-8105 (AKC 2012/07/22)
+ - h5dump: Fixed the sort by name display to maintain correct parent/child
+ relationships between ascending/descending order.
+ HDFFV-8095 (ADB 2012/07/12)
+ - h5dump: Fixed the display by creation order when using option -n
+ (print contents).
+ HDFFV-5942 (ADB 2012/07/09)
+ - h5dump: Changed to allow H5T_CSET_UTF8 to be displayed in h5dump output.
+ Used technique similar to what was done in h5ls (matches library
+ options).
+ HDFFV-7999 (ADB 2012/05/23)
+ - h5diff: Fixed the tool so that it will not check and display the status
+ of dangling links without setting the --follow-symlinks option. This
+ also improved performance when comparing lots of external links without
+ the --follow-symlinks option.
+ HDFFV-7998 (JKM 2012/04/26)
+
+ F90 API
+ -------
+
+ - Fixed a typo in return value of the nh5dread_f_c function (was 1
+ instead of 0 on success); fixed the return value to make it consistent
+ with other Fortran functions; cleaned debug statements from the code.
+ (EIP - 2012/06/23)
+
+ - Fixed a problem writing/reading control characters to a dataset; writing
+ a string containing alerts, backspace, carriage_return, form_feed,
+ horizontal_tab, vertical_tab, or new_line is now tested and working.
+ (MSB - 2012/09/01)
+
+ - Corrected the integer type of H5S_UNLIMITED_F to HSIZE_T (MSB - 2012/09/01)
+
+ - Corrected the number of continuation lines in the src files
+ to be less than 32 lines for F95 compliance. (MSB - 2012/10/01)
+
+ C++ API
+ ------
+ - None
+
+ High-Level APIs:
+ ------
+
+ - Fixed problem with H5TBdelete_record destroying all data following the
+ deletion of a row. (MSB- 2012/7/26)
+
+ - Fixed H5LTget_attribute_string not closing an object identifier when an
+ error occurs. (MSB- 2012/7/21)
+
+ - Corrected the return type of H5TBAget_fill from herr_t to htri_t to
+ reflect that a return value of 1 indicates that a fill value is
+ present, 0 indicates a fill value is not present, and <0 indicates an
+ error.
+
+ Fortran High-Level APIs:
+ ------
+ - None

+
+Known Problems
+==============
+* The following h5stat test case fails in BG/P machines (and potentially other
+ machines that display extra output if an MPI task returns with a non-zero
+ code.)
+ Testing h5stat notexist.h5
+
+ The test actually runs and passes as expected. It is the extra output from
+ the MPI process that causes the test script to fail. This will be fixed
+ in the next release. (AKC - 2012/10/25 - HDFFV-8233)
+
+* 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 kernal) 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)
+
+* 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)
+
+* The library's test dt_arith.c showed a compiler's rounding problem on
+ Cygwin when converting from unsigned long long to long double. The
+ library's own conversion works fine. We defined a macro for Cygwin to
+ skip this test until we can solve the problem.
+ (SLU - 2010/05/05 - HDFFV-1264)
+
+* 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. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.

+- Known Problems
+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - None
+
+ Library
+ -------
+ - Added new feature to merge committed datatypes when copying objects,
+ using new H5O_COPY_MERGE_COMMITTED_DTYPE_FLAG, modified by new API
+ routines: H5Padd_merge_committed_dtype_path(),
+ H5Pfree_merge_committed_dtype_paths(), H5Pset_mcdt_search_cb() and
+ H5Pget_mcdt_search_cb(). (QAK - 2012/03/30)
+ - Added new feature which allows working with files in memory in the
+ same ways files are worked with on disk. New API routines include
+ H5Pset_file_image, H5Pget_file_image, H5Pset_file_image_callbacks,
+ H5Pget_file_image_callbacks, H5Fget_file_image, and
+ H5LTopen_file_image. (QAK - 2012/04/17)
+
+ Parallel Library
+ ----------------
+ - Corrected memory allocation error in MPI datatype construction code.
+ (QAK - 2012/04/23)
+ - Add two new routines to set/get the atomicity parameter in the
+ MPI library to perform atomic operations. Some file systems (for
+ example PVFS2) do not support atomic updates, so those routines
+ would not be supported. (MSC - 2012/03/27 - HDFFV-7961)
+
+ Tools
+ -----
+ - h5repack: Added ability to set the metadata block size of the output
+ file, with the '-M'/'--metadata_block_size' command line parameter.
+ (QAK - 2012/03/30)
+ - h5stat: Added ability to display a summary of the file space usage for a
+ file, with the '-S'/'--summary' command line parameter. (QAK - 2012/03/28)
+ - h5dump: Added capability for "-a" option to show attributes containing "/"
+ by using an escape character. For example, for a dataset "/dset"
+ containing attribute "speed(m/h)", use "h5dump -a "/dset/speed(\/h)"
+ to show the content of the attribute. (PC - 2012/03/12 - HDFFV-7523)
+ - h5dump: Added ability to apply command options across multiple files using a
+ wildcard in the filename. Unix example; "h5dump -H -d Dataset1 tarr*.h5".
+ Cross platform example; "h5dump -H -d Dataset1 tarray1.h5 tarray2.h5 tarray3.h5".
+ (ADB - 2012/03/12 - HDFFV-7876).
+ - h5dump: Added new option --no-compact-subset. This option will not
+ interpret the '[' character as starting the compact form of
+ subsetting. This is useful when the "h5dump error: unable to
+ open dataset "datset_name"" message is output because a dataset
+ name contains a '[' character. (ADB - 2012/03/05 - HDFFV-7689).
+ - h5repack: Improved performance for big chunked datasets (size > 128MB)
+ when used with the layout (-l) or compression (-f) options.
+ Before this change, repacking datasets with chunks with a large first
+ dimension would take extremely long. For example, repacking a dataset
+ with chunk dimensions of 1024x5x1 might take many hours to process
+ while changing a dataset with chunk dimensions set to 1x5x1024
+ might take under an hour. After this change, processing the dataset
+ with chunk dimensions of 1024x5x1 takes about 15 minutes, and processing
+ a dataset with chunk dimensions of 1x5x1024 takes about 14 minutes.
+ (JKM - 2012/03/01 - HDFFV-7862)
+
+ High-Level APIs
+ ---------------
+ - New API: H5LTpath_valid (Fortran: h5ltpath_valid_f) checks
+ if a path is correct, determines if a link resolves to a valid
+ object, and checks that the link does not dangle. (MSB - 2012/03/15)
+
+ Fortran API
+ -----------
+
+ - Added for the C API the Fortran wrapper:
+ h5ocopy_f (MSB - 2012/03/22)
+
+ C++ API
+ -------
+ - None
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - None
+
+Bug Fixes since HDF5-1.8.8
+==========================
+
+ Configuration
+ -------------
+ - Fixed Makefile issue in which "-Wl," was not properly specified
+ prior to -rpath when building parallel Fortran libraries with
+ an Intel compiler. (MAM - 2012/03/26)
+ - Makefiles generated by other packages using h5cc as the compiler
+ no longer error when 'make' is invoked more than once in order
+ to 'rebuild' after changes to source. (MAM - 2012/03/26)
+ - Added code to display the version information of XL Fortran and C++
+ in the summary of configure. (AKC - 2012/02/28 - HDFFV-7793)
+ - Updated all CMakeLists.txt files to indicate the minimum CMake version is
+ the current standard of 2.8.6 (ADB - 2011/12/05 - HDFFV-7854)
+
+ Library
+ -------
+ - Windows and STDIO correctness changes have been propagated from the SEC2
+ and old Windows drivers to the STDIO VFD. (DER - 2012/03/30 - HDFFV-7917)
+ - Fixed an error that would occur when copying an object with attribute
+ creation order tracked and indexed. (NAF - 2012/03/28 - HDFFV-7762)
+ - Fixed a bug in H5Ocopy(): When copying an opened object, call the
+ object's flush class action to ensure that cached data is flushed so
+ that H5Ocopy will get the correct data. (VC - 2012/03/27 - HDFFV-7853)
+ - The istore test will now skip the sparse 50x50x50 test when the VFD does
+ not support sparse files on that platform. The most important platforms
+ on which this will be skipped are Windows (NTFS sparse files are not
+ supported) and Mac OS-X (HFS sparse files are not supported). This
+ fixes CTest timeout issues on Windows. (DER - 2012/03/27 - HDFFV-7769)
+ - Windows and POSIX correctness changes have been propagated from the SEC2
+ VFD to the Core VFD. This mainly affects file operations on the
+ driver's backing store and fixes a problem on Windows where large files
+ could not be read. (DER - 2012/03/27 - HDFFV-7916 - HDFFV-7603)
+ - When an application tries to write or read many small data chunks and
+ runs out of memory, the library had a segmentation fault. The fix is to
+ return the error stack with proper information.
+ (SLU - 2012/03/23 - HDFFV-7785)
+ - H5Pset_data_transform had a segmentation fault in some cases like x*-100.
+ It works correctly now and handles other cases like 100-x or 2/x.
+ (SLU - 2012/03/15 - HDFFV-7922)
+ - Fixed rare corruption bugs that could occur when using the new object
+ header format. (NAF - 2012/03/15 - HDFFV-7879)
+ - Fixed an error that occurred when creating a contiguous dataset with a
+ zero-sized dataspace and space allocation time set to 'early'.
+ (QAK - 2012/03/12)
+ - Changed Windows thread creation to use _beginthread() instead of
+ CreateThread(). Threads created by the latter can be killed in
+ low-memory situations. (DER - 2012/02/10 - HDFFV-7780)
+ - Creating a dataset in a read-only file caused a segmentation fault when
+ the file is closed. It's fixed. The attempt to create a dataset will
+ fail with an error indicating the file is read-only.
+ (SLU - 2012/01/25 - HDFFV-7756)
+ - Fixed a segmentation fault that could occur when shrinking a dataset
+ with chunks larger than 1 MB. (NAF - 2011/11/30 - HDFFV-7833)
+ - Fixed a bug that could cause H5Oget_info to return the wrong address
+ after copying a committed (named) datatype. (NAF - 2011/11/14)
+ - The library allowed the conversion of strings between ASCII and UTF8
+ We have corrected it to report an error under this situation.
+ (SLU - 2011/11/8 - HDFFV-7582)
+ - Fixed a segmentation fault when the library tried to shrink the size
+ of a compound datatype through H5Tset_size immediately after the
+ datatype was created. (SLU - 2011/11/4 - HDFFV-7618)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5unjam: Fixed a segmentation fault that occurred when h5unjam was used
+ with the -V (show version) option. (JKM - 2012/04/19 - HDFFV-8001)
+ - h5repack: Fixed a failure that occurred when repacking the chunk size
+ of a specified chunked dataset with unlimited max dims.
+ (JKM - 2012/04/11 - HDFFV-7993)
+ - h5diff: Fixed a failure when comparing groups. Before the fix, if an
+ object in a group was compared with an object in another group where
+ both had the same name but the object type was different, then h5diff
+ would fail. After the fix, h5diff detects such cases as non-comparable
+ and displays appropriate error messages.
+ (JKM - 2012/03/28 - HDFFV-7644)
+ - h5diff: If unique objects exist only in one file and if h5diff is set to
+ exclude the unique objects with the --exclude-path option, then h5diff
+ might miss excluding some objects. This was fixed to correctly exclude
+ objects. (JKM - 2012/03/20 - HDFFV-7837)
+ - h5diff: When two symbolic dangling links are compared with the
+ --follow-symlinks option, the result should be the same. This worked when
+ comparing two files, but didn't work when comparing two objects.
+ h5diff now works when comparing two objects.
+ (JKM - 2012/03/09 - HDFFV-7835)
+ - h5dump: Added the tools library error stack to properly catch error
+ information generated within the library. (ADB - 2012/03/12 - HDFFV-7958)
+ - h5dump: Changed the process where an open link used to fail. Now dangling
+ links no longer throw error messages. (ADB - 2012/03/12 - HDFFV-7839)
+ - h5dump: Refactored code to remove duplicated functions. Split XML
+ functions from DDL functions. Corrected indentation and formatting
+ errors. Also fixed subsetting counting overflow (HDFFV-5874). Verified
+ all tools call tools_init() in main. The USER_BLOCK data now correctly
+ displays within the SUPER_BLOCK info. NOTE: WHITESPACE IN THE OUTPUT
+ HAS CHANGED. (ADB - 2012/02/17 - HDFFV-7560)
+ - h5diff: Fixed to prevent from displaying error stack message when
+ comparing two dangling symbolic links with the follow-symlinks option.
+ (JKM - 2012/01/13 - HDFFV-7836)
+ - h5repack: Fixed a memory leak that occurred with the handling of
+ variable length strings in attributes.
+ (JKM - 2012/01/10 - HDFFV-7840)
+ - h5ls: Fixed a segmentation fault that occurred when accessing region
+ reference data in an attribute. (JKM - 2012/01/06 - HDFFV-7838)

+
+Known Problems
+==============
+* The h5repacktst test fails on AIX 32-bit because the test uses more
+ memory than the default amount. The failure message typically looks like:
+
+ "time: 0551-010 The process was stopped abnormally. Try again."
+
+ This is an issue with the test only and does not represent a problem with
+ the library. To allow the test to pass, request more memory when testing
+ via appropriate command such as:
+
+ $ env LDR_CNRTL=MAXDATA=0x20000000@DSA make check
+
+ (AKC - 2012/05/09 - HDFFV-8016)
+
+* The file_image test will fail in the "initial file image and callbacks in
+ the core VFD" sub-test if the source directory is read-only as the test
+ fails to create its test files in the build directory. This will be
+ resolved in a future release.
+ (AKC - 2012/05/05 - HDFFV-8009)
+
+* The dt_arith test reports several errors involving "long double" on
+ Mac OS X 10.7 Lion when any level of optimization is enabled. The test does
+ not fail in debug mode. This will be addressed in a future release.
+ (SLU - 2012/05/08)
+
+* 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)
+
+* The ph5diff (parallel h5diff) tool can intermittently hang in parallel mode
+ when comparing two HDF5 files that contain objects with the same names but
+ with different object types.
+ (JKM - 2012/04/27)
+
+* 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 kernal) 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)
+
+* 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)
+
+* 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)
+
+* The library's test dt_arith.c showed a compiler's rounding problem on
+ Cygwin when converting from unsigned long long to long double. The
+ library's own conversion works fine. We defined a macro for Cygwin to
+ skip this test until we can solve the problem.
+ (SLU - 2010/05/05 - HDFFV-1264)
+
+* 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)
+
+* MinGW has a missing libstdc++.dll.a library file and will not successfully link
+ C++ applications/tests. Do not use the enable-cxx configure option. Read all of
+ the INSTALL_MINGW.txt file for all restrictions.
+ (ADB - 2009/11/11)
+
+* 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)
+
+* The PathScale MPI implementation, accessing a Panasas file system, would
+ cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file does not
+ exist. This is due to the MPI_File_open() call failing if the mode has
+ the MPI_MODE_EXCL bit set.
+ (AKC - 2009/08/11 - HDFFV-988)
+
+* 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)
+
+* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh and
+ tools/h5copy/testh5copy.sh will fail some of its sub-tests. These sub-tests
+ are expected to fail and should exit with a non-zero code but the yod
+ command does not propagate the exit code of the executables. Yod always
+ returns 0 if it can launch the executable. The test suite shell expects
+ a non-zero for this particular test, therefore it concludes the test has
+ failed when it receives 0 from yod. Skip all the "failing" test for now
+ by changing them as following.
+
+ ======== Original tools/h5ls/testh5ls.sh =========
+ TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5
+ ======== Change to ===============================

+ ==================================================
+ (AKC - 2008/11/10)
+
+* For Red Storm, a Cray XT3 system, the yod command sometimes gives the
+ message, "yod allocation delayed for node recovery". This interferes with
+ test suites that do not expect to see this message. See the section of "Red
+ Storm" in file INSTALL_parallel for a way to deal with this problem.
+ (AKC - 2008/05/28)
+
+* 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. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
+ the application asks to do collective IO, we have found that when using 4
+ processors, a simple collective write will sometimes be hung. This can be
+ verified with t_mpi test under testpar.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+ (SLU - 2005/06/30)
+
+* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
+ messages like "INFO: 0031-XXX ...". This is from the command `poe'.
+ Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
+ and run the tests again.
+
+ The tests may fail with messages like "The socket name is already in use",
+ but HDF5 does not use sockets. This failure is due to problems with the
+ poe command trying to set up the debug socket. To resolve this problem,
+ check to see whether there are many old /tmp/s.pedb.* files staying around.
+ These are sockets used by the poe command and left behind due to failed
+ commands. First, ask your system administrator to clean them out.
+ Lastly, request IBM to provide a means to run poe without the debug socket.

+- New Features
+- Support for New Platforms, Languages, and Compilers
+- Bug Fixes since HDF5-1.8.7
+- Platforms Tested
+- Supported Configuration Features Summary
+- Known Problems
+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - Added the --enable-fortran2003 flag to enable Fortran2003 support
+ in the HDF5 Fortran library. The flag should be used along with the
+ --enable-fortran flag and takes affect only when the Fortran compiler
+ is Fortran2003 compliant. (EIP - 2011/11/14)
+ - Added checks for clock_gettime and mach/mach_time.h to both configure and
+ CMake. This will support the move from gettimeofday to clock_gettime's
+ monotonic timer in the profiling code in a future release.
+ (DER - 2011/10/12)
+
+ Library
+ -------
+ - The Windows VFD code has been removed with the exception of the functions
+ which set it (H5Pset_fapl_windows, for example). Setting the Windows
+ VFD now really sets the SEC2 VFD. The WINDOWS_MAX_BUF and
+ WINDOWS_USE_STDIO configuration options and #defines have also been
+ removed. NOTE: Since the Windows VFD was a clone of the SEC2 VFD, this
+ change should be transparent to users.
+ (DER - 2011/10/12 - HDFFV-7740, HDFFV-7744)
+ - H5Tcreate now supports the string type (fixed-length and variable-
+ length). (SLU - 2011/05/20)
+
+ Parallel Library
+ ----------------
+ - Added new H5Pget_mpio_actual_chunk_opt_mode and
+ H5Pget_mpio_actual_io_mode API routines for querying whether/how
+ a collective I/O operation completed. (QAK - 2011/10/12)
+
+ Tools
+ -----
+ - None
+
+ High-Level APIs
+ ---------------
+ - Added the following Fortran wrappers for the Dimension Scale APIs:
+ h5dsset_scale_f
+ h5dsattach_scale_f
+ h5dsdetach_scale_f
+ h5dsis_attached_f
+ h5dsis_scale_f
+ h5dsset_label_f
+ h5dsget_label_f
+ h5dsget_scale_name_f
+ h5dsget_num_scales_f
+ (EIP for SB - 2011/10/13 - HDFFV-3797)
+
+ Fortran API
+ -----------
+ - The HDF5 Fortran library was enhanced to support the Fortran 2003 standard.
+ The following features are available when the HDF5 library is configured
+ using the --enable-fortran and --enable-fortran2003 configure flags AND
+ if the Fortran compiler is Fortran 2003 compliant:
+
+ - Subroutines overloaded with the C_PTR derived type:
+ h5pget_f
+ h5pget_fill_value_f
+ h5pinsert_f
+ h5pregister_f
+ h5pset_f
+ h5pset_fill_value_f
+ h5rcreate_f
+ h5rderefrence_f
+ h5rget_name_f
+ h5rget_obj_type_f
+ - Subroutines overloaded with the C_PTR derived type
+ and simplified signatures:
+ h5aread_f
+ h5awrite_f
+ h5dread_f
+ h5dwrite_f
+ - New subroutines
+ h5dvlen_reclaim_f
+ h5literate_by_name_f
+ h5literate_f
+ h5ovisit_f
+ h5tconvert_f
+ h5pset_nbit_f
+ h5pset_scaleoffset_f
+ - Subroutines with additional optional parameters:
+ h5pcreate_class_f
+ (EIP - 2011/10/14)
+
+ C++ API
+ -------
+ - None
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - None
+
+Bug Fixes since HDF5-1.8.7
+==========================
+
+ Configuration
+ -------------
+ - Changed the size of H5_SIZEOF_OFF_T to 4 bytes (was 8) in the VMS
+ h5pubconf.h based on the output of a test program. (DER - 2011/10/12)
+ - The Windows and VMS versions of H5pubconf.h were brought into sync with
+ the linux/posix version. (DER - 2011/10/12)
+ - Fixed a bug in the bin/trace Perl script where API functions
+ that take a variable number of arguments were not processed for
+ trace statement fixup. (DER - 2011/08/25)
+ - The --enable-h5dump-packed-bits configure option has been removed.
+ The h5dump code that this option conditionally enabled is now always
+ compiled into h5dump. Please refer to the h5dump reference manual for
+ usage of the packed bits feature. (MAM - 2011/06/23 - HDFFV-7592)
+ - Configure now uses the same flags and symbols in its tests that are
+ used to build the library. (DER - 2011/05/24)
+
+ Library
+ -------
+ - Corrected the error when copying attributes between files which are using
+ different versions of the file format. (QAK - 2011/10/20 - HDFFV-7718)
+ - Corrected the error when loading local heaps from the file, which could
+ cause the size of the local heap's data block to increase dramatically.
+ (QAK - 2011/10/14 - HDFFV-7767)
+ - An application does not need to do H5O_move_msgs_forward() when writing
+ attributes. Tests were checked into the performance suite.
+ (VC - 2011/10/13 - HDFFV-7640)
+ - Fixed a bug that occurred when using H5Ocopy on a committed datatype
+ containing an attribute using that committed datatype.
+ (NAF - 2011/10/13 - HDFFV-5854)
+ - Added generic VFD I/O types to the SEC2 and log VFDs to ensure correct
+ I/O sizes (and remove compiler warnings) between Windows and true POSIX
+ systems. (DER - 2011/10/12)
+ - Corrected some Windows behavior in the SEC2 and log VFDs. This mainly
+ involved datatype correctness fixes, Windows API call error checks,
+ and adding the volume serial number to the VFD cmp functions.
+ (DER - 2011/10/12)
+ - Converted post-checks for the appropriate POSIX I/O sizes to pre-checks
+ in order to avoid platform-specific or undefined behavior.
+ (DER - 2011/10/12)
+ - #ifdef _WIN32 instances have been changed to #ifdef H5_HAVE_WIN32_API.
+ H5_HAVE_VISUAL_STUDIO checks have been added where necessary. This is in
+ CMake only as configure never sets _WIN32. (ADB - 2011/09/12)
+ - CLANG compiler with the options -fcatch-undefined-behavior and -ftrapv
+ discovered 3 problems in tests and tools' library:
+ 1. In dsets.c, left shifting an unsigned int for 32 bits or more
+ caused undefined behavior.
+ 2. In dt_arith.c, the INIT_INTEGER macro definition has an overflow
+ when the value is a negative minimal and is being subtracted from one.
+ 3. In tools/lib/h5tools_str.c, right shifting an int value for 32 bits
+ or more caused undefined behavior.
+ All the problems have been corrected. (SLU - 2011/09/02 - HDFFV-7674)
+ - H5Epush2() now has the correct trace functionality (this is related to the
+ bin/trace Perl script bug noted in the configure section).
+ (DER - 2011/08/25)
+ - Corrected mismatched function name typo of h5pget_dxpl_mpio_c and
+ h5pfill_value_defined_c. (AKC - 2011/08/22 - HDFFV-7641)
+ - Corrected an internal error in the library where objects that use committed
+ (named) datatypes and were accessed from two different file IDs could confuse
+ the two and cause erroneous failures. (QAK - 2011/07/18 - HDFFV-7638)
+ - In v1.6 of the library, there was an EOA for the whole MULTI file saved in the
+ super block. We took it out in v1.8 of the library because it's meaningless
+ for the MULTI file. v1.8 of the library saves the EOA for the metadata file
+ instead, but this caused a backward compatibility problem.
+ A v1.8 library couldn't open the file created with the v1.6 library. We
+ fixed the problem by checking the EOA value to detect the file
+ created with v1.6 library. (SLU - 2011/06/22)
+ - When a dataset had filters and reading data failed, the error message
+ didn't say which filter wasn't registered. It's fixed now. (SLU - 2011/06/03)
+
+ Parallel Library
+ ----------------
+ - The Special Collective IO (IO when some processes do not contribute to the
+ IO) and the Complex Derived Datatype MPI functionalities are no longer
+ conditionally enabled in the library by configure. They are always
+ enabled in order to take advantage of performance boosts from these
+ behaviors. Older MPI implementations that do not allow for these
+ functionalities can no longer by used by HDF5.
+ (MAM - 2011/07/08 - HDFFV-7639).
+
+ Tools
+ -----
+ - h5diff: fixed segfault over non-comparable attribute with different
+ dimention or rank, along with '-c' option to display details.
+ (JKM - 2011/10/24 - HDFFV-7770)
+ - Fixed h5diff to display all the comparable objects and attributes
+ regardless of detecting non-comparables. (JKM - 2011/09/16 - HDFFV-7693)
+ - Fixed h5repack to update the values of references(object and region) of
+ attributes in h5repack for 1) references, 2) arrays of references,
+ 3) variable-length references, and 4) compound references.
+ (PC - 2011/09/14 - HDFFV-5932)
+ - h5diff: fixed a segfault over a dataset with container types
+ array and variable-length (vlen) along with multiple nested compound types.
+ Example: compound->array->compound, compound->vlen->compound.
+ (JKM - 2011/09/01 - HDFFV-7712)
+ - h5repack: added macro to handle a failure in H5Dread/write when memory
+ allocation failed inside the library. (PC - 2011/08/19)
+ - Fixed h5jam to not to allow the specifying of an HDF5 formatted file as
+ an input file for the -u (user block file) option. The original HDF5 file
+ would not be accessible if this behavior was allowed.
+ (JKM - 2011/08/19 - HDFFV-5941)
+ - Revised the command help pages of h5jam and h5unjam. The descriptions
+ were not up to date and some were missing.
+ (JKM - 2011/08/15 - HDFFV-7515)
+ - Fixed h5dump to correct the schema location:
+ <hdf5:HDF5-File
+ xmlns:hdf5="http://hdfgroup.org/HDF5/XML/schema/HDF5-File"
+ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+ xsi:schemaLocation="http://hdfgroup.org/HDF5/XML/schema/HDF5-File
+ http://www.hdfgroup.org/HDF5/XML/schema/HDF5-File.xsd">
+ (ADB - 2011/08/10)
+ - h5repack: h5repack failed to copy a dataset if the layout is changed
+ from chunked with unlimited dimensions to contiguous.
+ (PC - 2011/07/15 - HDFFV-7649)
+ - Fixed h5diff: the "--delta" option considers two NaN of the same type
+ are different. This is wrong based on the h5diff description in the
+ Reference Manual. (PC - 2011/07/15 - HDFFV-7656)
+ - Fixed h5diff to display an instructive error message and exit with
+ an instructive error message when mutually exclusive options
+ (-d, -p and --use-system-epsilon) are used together.
+ (JKM - 2011/07/07 - HDFFV-7600)
+ - Fixed h5dump so that it displays the first line of each element in correct
+ position for multiple dimention array types. Before this fix,
+ the first line of each element in an array was
+ displayed after the last line of previous element without
+ moving to the next line (+indentation).
+ (JKM - 2011/06/15 - HDFFV-5878)
+ - Fixed h5dump so that it will display the correct value for
+ H5T_STD_I8LE datasets on the Blue-gene system (ppc64, linux, Big-Endian,
+ clustering). (AKC & JKM - 2011/05/12 - HDFFV-7594)
+ - Fixed h5diff to compare a file to itself correctly. Previously h5diff
+ reported either the files were different or not compatible in certain
+ cases even when comparing a file to itself. This fix also improves
+ performance when comparing the same target objects through verifying
+ the object and file addresses before comparing the details
+ in the objects. Examples of details are datasets and attributes.
+ (XCAO & JKM - 2011/05/06 - HDFFV-5928)
+
+ F90 API
+ -------
+ - Modified the h5open_f and h5close_f subroutines to not to call H5open
+ and H5close correspondingly. While the H5open call just adds overhead,
+ the H5close call called by a Fortran application shuts down the HDF5
+ library. This makes the library inaccessible to the application.
+ (EIP & SB - 2011/10/13 - HDFFV-915)
+ - Fixed h5tget_tag_f where the length of the C string was used to
+ repack the C string into the Fortran string. This lead to memory
+ corruption in the calling program. (SB - 2011/07/26)
+ - Added defined constants:
+ H5T_ORDER_MIXED_F (HDFFV-2767)
+ H5Z_SO_FLOAT_DSCALE_F
+ H5Z_SO_FLOAT_ESCALE_F
+ H5Z_SO_INT_F
+ H5Z_SO_INT_MINBITS_DEFAULT_F
+ H5O_TYPE_UNKNOWN_F
+ H5O_TYPE_GROUP_F
+ H5O_TYPE_DATASET_F
+ H5O_TYPE_NAMED_DATATYPE_F
+ H5O_TYPE_NTYPES_F
+
+ C++ API
+ ------
+ - None
+
+ High-Level APIs:
+ ------
+ - Fixed the H5LTdtype_to_text function. It had some memory problems when
+ dealing with some complicated data types. (SLU - 2011/10/19 - HDFFV-7701)
+ - Fixed H5DSset_label seg faulting when retrieving the length of a
+ dimension label that was not set. (SB - 2011/08/07 - HDFFV-7673)
+ - Fixed a dimension scale bug where if you create a dimscale, attach two
+ datasets to it, and then unattach them, you get an error if they are
+ unattached in order, but no error if you unattach them in reverse order.
+ (SB - 2011/06/07 - HDFFV-7605)
+
+ Fortran High-Level APIs:
+ ------
+ - None

+
+Known Problems
+==============
+
+* 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, possibly 1.8.9.
+ (DER - 2011/10/14)
+
+* 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 the next 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)
+
+* The library's test dt_arith.c showed a compiler's rounding problem on
+ Cygwin when converting from unsigned long long to long double. The
+ library's own conversion works fine. We defined a macro for Cygwin to
+ skip this test until we can solve the problem.
+ (SLU - 2010/05/05 - HDFFV-1264)
+
+* 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)
+
+* MinGW has a missing libstdc++.dll.a library file and will not successfully link
+ C++ applications/tests. Do not use the enable-cxx configure option. Read all of
+ the INSTALL_MINGW.txt file for all restrictions. (ADB - 2009/11/11)
+
+* 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)
+
+* The PathScale MPI implementation, accessing a Panasas file system, would
+ cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file does not
+ exist. This is due to the MPI_File_open() call failing if the mode has
+ the MPI_MODE_EXCL bit set. (AKC - 2009/08/11 - HDFFV-988)
+
+* 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)
+
+* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh and
+ tools/h5copy/testh5copy.sh will fail some of its sub-tests. These sub-tests
+ are expected to fail and should exit with a non-zero code but the yod
+ command does not propagate the exit code of the executables. Yod always
+ returns 0 if it can launch the executable. The test suite shell expects
+ a non-zero for this particular test, therefore it concludes the test has
+ failed when it receives 0 from yod. Skip all the "failing" test for now
+ by changing them as following.
+
+ ======== Original tools/h5ls/testh5ls.sh =========
+ TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5
+ ======== Change to ===============================
+ echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5

+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets
+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested

+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets
+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested
+ echo SKIP H5LSTEST $FILEOUT
+ ==================================================
+ (AKC - 2008/11/10)
+
+* For Red Storm, a Cray XT3 system, the yod command sometimes gives the
+ message, "yod allocation delayed for node recovery". This interferes with
+ test suites that do not expect to see this message. See the section of "Red
+ Storm" in file INSTALL_parallel for a way to deal with this problem.
+ (AKC - 2008/05/28)
+
+* 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. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
+ the application asks to do collective IO, we have found that when using 4
+ processors, a simple collective write will sometimes be hung. This can be
+ verified with t_mpi test under testpar.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+ (SLU - 2005/06/30)
+
+* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
+ messages like "INFO: 0031-XXX ...". This is from the command `poe'.
+ Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
+ and run the tests again.
+
+ The tests may fail with messages like "The socket name is already in use",
+ but HDF5 does not use sockets. This failure is due to problems with the
+ poe command trying to set up the debug socket. To resolve this problem,
+ check to see whether there are many old /tmp/s.pedb.* files staying around.
+ These are sockets used by the poe command and left behind due to failed
+ commands. First, ask your system administrator to clean them out.
+ Lastly, request IBM to provide a means to run poe without the debug socket.

+- New Features
+- Support for New Platforms, Languages, and Compilers
+- Bug Fixes since HDF5-1.8.6
+- Platforms Tested
+- Supported Configuration Features Summary
+- Known Problems
+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - Configure now generates Makefiles that build in "silent make mode"
+ by default in which compile and link lines are significantly
+ simplified for clarity. To override this and view actual compile and
+ link lines during building, the --disable-silent-rules flag can be used
+ at configure time, or the 'make' command can be followed by V=1, to
+ indicate a "verbose" make. (MAM - 2011/4/14).
+ - Added mpicc and mpif90 as the default C and Fortran compilers for Linux
+ systems when --enable-parallel is specified but no $CC or $FC is defined.
+ (AKC - 2011/2/7)
+ - Added a new configure option, "--enable-unsupported", which can
+ be used to stop configure from preventing the use of unsupported
+ configure option combinations, such as c++ in parallel or Fortran
+ with threadsafe. Use at your own risk, as it may result in a
+ library that won't compile or run as expected!
+ (MAM - 2010/11/17 - Bug 2061)
+
+ Library
+ -------
+ - The library allows the dimension size of a dataspace to be zero. In
+ the past, the library would allow this only if the maximal dimension
+ size was unlimited. Now there is no such restriction, but no data
+ can be written to this kind of dataset. (SLU - 2011/4/20)
+ - We added two new macros, H5_VERSION_GE and H5_VERSION_LE, to let users
+ compare certain version numbers with the library being used. (SLU -
+ 2011/4/20)
+ - Added ability to cache files opened through external links. Added new
+ public functions H5Pset_elink_file_cache_size(),
+ H5Pget_elink_file_cache_size(), and H5Fclear_elink_file_cache().
+ (NAF - 2011/02/17)
+ - Finished implementing all options for 'log' VFD. (QAK - 2011/1/25)
+ - Removed all old code for Metrowerks compilers, bracketed by
+ __MWERKS__). Metrowerks compiler is long gone. (AKC - 2010/11/17)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5diff: Added new "verbose with levels" option, '-vN, --verbose=N'.
+ The old '-v, --verbose' option is deprecated but remains available;
+ it is exactly equivalent to '-v0, --verbose=0'.
+ The new levels 1 ('-v1' or '--verbose=1') and 2 ('-v2' or
+ '--verbose=2') can be specified to view more information regarding
+ attributes differences. Bug #2121 (JKM 2011/3/23)
+ - h5dump: Added new option --enable-error-stack. This option will
+ display error stack information in the output stream. This is
+ useful when the "h5dump: Unable to print data" message is output.
+ (ADB - 2011/03/03)
+
+ High-Level APIs
+ ---------------
+ - Fortran LT make datasets routines (H5LTmake_dataset_f,
+ h5ltmake_dataset_int_f, h5ltmake_dataset_float_f, h5ltmake_dataset_double_f)
+ and LT read datasets routines (h5ltread_dataset_f,h5ltread_dataset_int_f,
+ h5ltread_dataset_float_f, 5ltread_dataset_double_f) can now handle
+ 4-dimensional to 7-dimensional rank datasets. HDFFV-1217 (MSB-2011/4/24/2011)
+
+ F90 API
+ -------
+ - None
+
+ C++ API
+ -------
+ - None
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - Intel V11.1 uses now -O3 optimization in production mode (EIP - 2010/10/08)
+
+
+
+Bug Fixes since HDF5-1.8.6
+==========================
+
+ Configuration
+ -------------
+ - Shared C++ and HL libraries on AIX should now be working correctly.
+ Note that Fortran shared libraries are still not working on AIX.
+ (See the Known Problems section, below). (MAM - 2011/4/20)
+ - Removed config/ibm-aix6.x. All IBM-AIX settings are in one file,
+ ibm-aix. (AKC - 2011/4/14)
+ - Shared C libraries are no longer disabled on Mac when Fortran
+ is enabled. Shared Fortran libraries are still not supported on Mac,
+ so configure will disable them by default, but this is overrideable
+ with the new --enable-unsupported configure option. The configure
+ summary has been updated to reflect the fact that the shared-ness of
+ the C++/Fortran wrapper libraries may not align with the C library.
+ (MAM - 2011/04/11 - HDFFV-4353).
+
+ Library
+ -------
+ - Changed assertion failure when decoding a compound datatype with no
+ fields into a normal error failure. Also prohibit using this sort
+ of datatype for creating an attribute (as is already the case for
+ datasets and committed (named) datatypes). (QAK - 2011/04/15, Jira
+ issue #HDFFV-2766)
+ - Tell the VFL flush call that the file will be closing, allowing
+ the VFDs to avoid sync'ing the file (particularly valuable in parallel).
+ (QAK - 2011/03/09)
+ - The datatype handler created with H5Tencode/decode used to have the
+ reference count 0 (zero); it now has the reference count 1 (one).
+ (SLU - 2011/2/18)
+ - Fixed the definition of H5_HAVE_GETTIMEOFDAY on Windows so that
+ HDgettimeofday() is defined and works properly. Bug HDFFV-5931
+ (DER - 2011/04/14)
+ - Added basic VFD tests for the Windows, STDIO and log VFD tests.
+ (DER - 2011/04/11)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - Updated h5dump test case script to prevent entire test failure when
+ source directory is read-only. Bug #HDFFV-4342 (JKM 2011/4/12)
+ - Fixed h5dump displaying incorrect values for H5T_STD_I8BE type data in
+ attribute on Big-Endian machine. H5T_STD_I8BE is unsigned 8bit type,
+ so h5dump is supposed to display -2 instead of 254. It worked correctly
+ on Little-Endian system , but not on Big-Endian system. Bug #HDFFV-4358
+ (JKM 04/08/2011)
+ - Updated some HDF5 tools to standardize the option name as
+ '--enable-error-stack' for printing HDF5 error stack messages. h5ls and
+ h5dump have been updated. For h5ls, this replaces "-e/--errors" option,
+ which is deprecated. For h5dump, this is a new option. Bug #2182
+ (JKM 2011/3/30)
+ - Fixed the h5diff --use-system-epsilon option. The formula used in the
+ calculation was changed from ( |a - b| / b ) to ( |a - b| ).
+ This was done to improve performance. Bug #2184 (JKM 2011/3/24)
+ - Fixed output for H5T_REFERENCE in h5dump. According to the BNF document
+ the output of a H5T_REFERENCE should be followed by the type;
+ <reference> ::= H5T_REFERENCE { <ref_type> }
+ <ref_type> ::= H5T_STD_REF_OBJECT | H5T_STD_REF_DSETREG
+ Previously this was only displayed if the -R option was used.
+ Bug #1725 (ADB 2011/3/28)
+ - Fixed two h5diff issues. 1) h5diff compared attributes correctly only
+ when two objects had the same number of attributes and the attribute
+ names were identical. 2) h5diff did not display useful information about
+ attribute differences. Bug #2121 (JKM 2011/3/17)
+ - Fixed a memory leak in h5diff that occurred when accessing symbolic links
+ with the --follow-symlink option. Bug #2214 (JKM 2011/3/18)
+ - Fixed a memory leak in h5diff that occurred when accessing variable length
+ string data. Bug #2216 (JKM 2011/3/18)
+ - Fixed and improved the help page for h5ls -a, --address option.
+ Bug #1904 (JKM 2011/3/11)
+ - Fixed h5copy to enable copying an object into the same HDF5 file.
+ Previously h5copy displayed an error message when the target file
+ was the same as the source file. (XCAO 2011/3/8)
+ - Fixed an h5dump problem that caused the tool to skip some data elements
+ in large datasets with a large array datatype on Windows. This issue
+ arose only on Windows due to the different return behavior of the
+ _vsnprintf() function. Bug #2161 (JKM 2011/3/3)
+ - Fixed h5dump which was skipping some array indices in large datasets
+ with a relatively large array datatype. The interval of skipped indices
+ varied according to the size of the array. Bug #2092 (JKM 2011/2/15)
+ - Fixed h5diff which was segfaulting when comparing compound datasets
+ with a combination of fixed-length string datatypes and variable-length
+ string datatypes in certain orders. Bug #2089 (JKM 2010/12/28)
+ - Improved h5diff performance. 1) Now use HDmemcmp() before comparing two
+ elements. 2) Replace expensive H5Tequals() calls. 3) Retrieve datatype
+ information at dataset level, not at each element level for compound
+ datasets. HDFFV-7516 (JKM 2011/4/18)
+ - Fixed h5ls to display nested compound types with curly brackets
+ when -S (--simple) option is used with -l (--label), so it shows
+ which members (in curly brackets) belong to which nested compound type,
+ making the output clearer. Bug #1979 (JKM 2010/11/09)
+ - Fixed h5diff to handle variable-length strings in a compound dataset
+ and variable-length string arrays in a compound dataset correctly.
+ Garbage values were previously displayed when h5diff compared multiple
+ variable-length strings in a compound type dataset.
+ Bug #1989 (JKM 2010/10/28)
+ - Fixed h5copy to fail gracefully when copying an object to a non-
+ existing group without the -p option. Bug #2040 (JKM 2010/10/18)

+
+Known Problems
+==============
+* 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
+
+* If parallel gmake (e.g., gmake -j 4) is used, the "gmake clean" command
+ sometimes fails in the perform directory due to the attempt to remove the
+ executable of h5perf or h5perf_serial by two "parallel" commands. This error
+ has no consequence on the functionality of the HDF5 library or install. It
+ is fixed in the next release. AKC - 2011/01/25
+
+* 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/
+
+* The library's test dt_arith.c showed a compiler's rounding problem on
+ Cygwin when converting from unsigned long long to long double. The
+ library's own conversion works fine. We defined a macro for Cygwin to
+ skip this test until we can solve the problem. Please see bug #1813.
+ SLU - 2010/5/5
+
+* 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 - 2010/2/2
+
+* MinGW has a missing libstdc++.dll.a library file and will not successfully link
+ C++ applications/tests. Do not use the enable-cxx configure option. Read all of
+ the INSTALL_MINGW.txt file for all restrictions. ADB - 2009/11/11
+
+* The PathScale MPI implementation, accessing a Panasas file system, would
+ cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file does not
+ exist. This is due to the MPI_File_open() call failing if the mode has
+ the MPI_MODE_EXCL bit set. (See bug 1468 for details.) AKC - 2009/8/11
+
+* 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
+
+* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh and
+ tools/h5copy/testh5copy.sh will fail some of its sub-tests. These sub-tests
+ are expected to fail and should exit with a non-zero code but the yod
+ command does not propagate the exit code of the executables. Yod always
+ returns 0 if it can launch the executable. The test suite shell expects
+ a non-zero for this particular test, therefore it concludes the test has
+ failed when it receives 0 from yod. Skip all the "failing" test for now
+ by changing them as following.

+ ==================================================
+ AKC - 2008/11/10
+
+* For Red Storm, a Cray XT3 system, the yod command sometimes gives the
+ message, "yod allocation delayed for node recovery". This interferes with
+ test suites that do not expect to see this message. See the section of "Red
+ Storm" in file INSTALL_parallel for a way to deal with this problem.
+ AKC - 2008/05/28
+
+* 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. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
+ the application asks to do collective IO, we have found that when using 4
+ processors, a simple collective write will sometimes be hung. This can be
+ verified with t_mpi test under testpar.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+ SLU - 2005/6/30
+
+* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
+ messages like "INFO: 0031-XXX ...". This is from the command `poe'.
+ Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
+ and run the tests again.
+
+ The tests may fail with messages like "The socket name is already in use",
+ but HDF5 does not use sockets. This failure is due to problems with the
+ poe command trying to set up the debug socket. To resolve this problem,
+ check to see whether there are many old /tmp/s.pedb.* files staying around.
+ These are sockets used by the poe command and left behind due to failed
+ commands. First, ask your system administrator to clean them out.
+ Lastly, request IBM to provide a means to run poe without the debug socket.
+
+* 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.
+
+* There is also a configure error on Altix machines that incorrectly reports
+ when a version of Szip without an encoder is being used.
+
+* On cobalt, an SGI Altix SMP ia64 system, Intel compiler version 10.1 (which
+ is the default on that system) does not work properly and results in
+ failures during make check (in a static build) and make installcheck (during
+ a shared build). This appears to be a compiler optimization problem.
+ Reducing optimization by setting CFLAGS to -O1 or below resolves the issue.
+ Alternatively, using a newer version of the compiler (11.0) also works as
+ intended. MAM - 2010/06/01
+
+* h5diff will not report enum value differences when one or both of the values
+ is not a valid enumeration value. The source of this bug has been identified
+ and it will be fixed in 1.8.8. DER - 2011/04/27

+- Bug Fixes since HDF5-1.8.5
+- Platforms Tested
+- Supported Configuration Features Summary
+- Known Problems
+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - CMake: Improved CPack packaging, added parallel commands, improved
+ configuration options (better similarity to configure), added more
+ tests, better support for use in external cmake projects.
+ (ADB - 2010/10/07)
+ - The default configuration setting for official releases is
+ --enable-production. For unofficial releases, the default configuration
+ setting has been --disable-production. (AKC - 2010/05/28)
+ Library
+ -------
+ - Added support for thread safety on Windows using the Windows threads
+ library. Use the HDF5_ENABLE_THREADSAFE option in CMake on a Windows
+ platform to enable this functionality. This is supported on Windows
+ Vista and newer Windows operating systems. (MAM - 2010/09/10)
+ - H5Tset_order and H5Tget_order now support all datatypes. A new byte
+ order, H5T_ORDER_MIXED, has been added specifically for a compound
+ datatype and its derived type. (SLU - 2010/8/23)
+ - Improved performance of metadata I/O by changing the default algorithm
+ to perform I/O from all processes (instead of just process 0) when using
+ parallel I/O drivers. (QAK - 2010/07/19)
+ - Improved performance of I/O on datasets with the same shape, but
+ different rank. (QAK - 2010/07/19)
+ - Improved performance of the chunk cache by avoiding unnecessary b-tree
+ lookups of chunks already in cache. (NAF - 2010/06/15)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5diff: Added a new flag: --exclude-path. The specified path to an
+ object will be excluded when comparing two files or two groups. If a
+ group is specified to be excluded, all member objects of that group
+ will be excluded. (JKM - 2010/09/16).
+ - h5ls: Added a new flag: --no-dangling-links. See --help output for
+ details. (JKM - 2010/06/15)
+ - h5ls: Added a new flag --follow-symlinks. See --help output for
+ details. (JKM - 2010/05/25)

+Support for New Platforms, Languages, and Compilers
+===================================================
+ - Sun C and C++ 5.10 and Sun Fortran 95 8.4.
+ - Mac OS X 10.6.4 with gcc 4.2.1 and gfortran 4.6
+
+
+Bug Fixes since HDF5-1.8.5
+==========================
+
+ Configuration
+ -------------
+ - The default number of MPI processes for testing purposes has been
+ changed from 3 to 6. (AKC - 2010/11/11)
+ - Some tests in tools/h5repack may fail in AIX systems when -q32 mode is
+ used. The error is caused by not requesting enough memory in default.
+ Added "env LDR_CNTRL=MAXDATA=0x20000000@DSA" into the $RUNSERIAL and
+ $RUNPARALLE in the AIX config file so that executables are tested with
+ more memory. (AKC - 2010/11/11)
+ - Removed recognition of the parallel compilers of LAM(hcc) and
+ ChMPIon(cmpicc) since we have no access to these two MPI implementations
+ and cannot verify their correctness. (AKC - 2010/07/14 - Bug 1921)
+ - PHDF5 was changed to use "mpiexec" instead of mpirun as the default
+ MPI applications startup command as defined in the MPI-2 definition,
+ section 4.1. (AKC - 2010/06/11 - Bug 1921)
+
+ Library
+ -------
+ - Fixed a bug that caused big endian machines to generate corrupt files
+ when using the scale-offset filter with floating point data or fill
+ values. Note that such datasets will no longer be readable by any
+ by any machine after this patch. (NAF - 2010/02/02 - Bug 2131)
+ - Retrieving a link's name by index in the case where the link is external
+ and the file that the link refers to doesn't exist will now fail
+ gracefully rather than cause a segmentation fault. (MAM - 2010/11/17)
+ - Modified metadata accumulator to better track accumulated dirty metadata
+ in an effort to reduce unnecessary I/O in certain situations and to
+ fix some other corner cases which were prone to error. (MAM - 2010/10/15)
+ - Added a new set of unit tests that are run during 'make check' to verify
+ the behavior of the metadata accumulator. (MAM - 2010/10/15)
+ - Modified library to always cache symbol table information. Libraries
+ from version 1.6.3 and earler have a bug which causes them to require
+ this information for some operations. (NAF - 2010/09/21 - Bug 1864)
+ - Fixed a bug where the library could generate an assertion/core dump when
+ a file that had been created with H5Pset_libver_bounds(fapl,
+ H5F_LIBVER_LATEST, H5F_LIBVER_LATEST) but didn't have a superblock
+ extension was later reopened. (QAK - 2010/09/16 - Bug 1968)
+ - Fixed a bug that could occur when getting information for a new-style
+ group that was previously opened through a file handle that was later
+ closed. (NAF - 2010/09/15)
+ - Added define check in H5public.h if stdint.h is supported by the C++
+ compiler. This define is only available on Windows with VS2010 and using
+ CMake to build the library. (ADB - 2010/09/13 - Bug 1938)
+ - When a mandatory filter failed to write data chunks, the dataset
+ couldn't close (bug 1260). The fix releases all resources and closes
+ the dataset but returns a failure. (SLU - 2010/09/08)
+ - H5Eset_current_stack now also closes the error stack set as the
+ default. This is to avoid a potential problem.
+ (SLU - 2010/09/07 - Bug 1799)
+ - Corrected situation where 1-D chunked dataset could get created by an
+ application without calling H5Pset_chunk(). H5Pset_chunk is now
+ required for creating all chunked datasets. (QAK - 2010/09/02)
+ - Fixed many memory issues that valgrind exposed. (QAK - 2010/08/24)
+ - Fixed the bug in the filter's public CAN_APPLY function. The return
+ value should be htri_t not herr_t. (SLU - 2010/08/05 - Bug 1239)
+ - Fixed the STDIO VFD to use fseeko64 instead of fseek64 for 64-bit I/O
+ support. (AKC - 2010/7/30)
+ - Fixed a bug in the direct I/O driver that could render files with certain
+ kinds of unaligned data unreadable or corrupt them. (NAF - 2010/07/28)
+ - valgrind reported an error of copying data to itself when a new attribute
+ is written. Fixed by taking out the memcpy step in the attribute code.
+ (SLU - 2010/07/28 - Bug 1956)
+ - Corrected various issues in the MPI datatype creation code which could
+ cause resource leaks or incorrect behavior (and may improve the
+ performance as well). (QAK - 2010/07/19)
+ - Fixed a bug that could cause file corruption when using non-default sizes
+ of addresses and/or lengths. This bug could also cause uncorrupted files
+ with this property to be unreadable. This bug was introduced in 1.8.5.
+ (NAF - 2010/07/16 - Bug 1951)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - Fixed h5diff to compare member objects and groups recursively when
+ two files or groups are compared. (JKM - 2010/9/16 - Bug 1975)
+ - Fixed h5repack to be able to convert a dataset to COMPACT layout.
+ (JKM - 2010/09/15 - Bug 1896)
+ - Changed h5ls to not interpret special characters in object or attribute
+ names for output. (JKM - 2010/06/28 - Bug 1784)
+ - Revised the order of arguments for h5cc, h5fc, h5c++, h5pcc and h5pfc.
+ CPPFLAGS, CFLAGS, LDFLAGS, and LIBS have been duplicated with an H5BLD_
+ prefix to put the flags and paths from the hdf5 build in the correct
+ places and allow the script user to add entries in CPPFLAGS, CFLAGS,
+ LDFLAGS, and LIBS that will take precedence over those from the hdf5
+ build. The user can make these entries persistent by editing
+ CFLAGSBASE, CPPFLAGSBASE, LDFLAGSBASE, and LIBSBASE near the top of
+ the script or temporary by setting HDF5_CFLAGS, HDF5_CPPFLAGS,
+ HDF5_LDFLAGS, or HDF5_LIBS in the environment. The new order of
+ arguments in these scripts is $CLINKER $H5BLD_CPPFLAGS $CPPFLAGS
+ $H5BLD_CFLAGS $CFLAGS $LDFLAGS $clibpath $link_objs $LIBS $link_args
+ $shared_link. (LRK - 2010/10/25 - Bug 1973)

+Known Problems
+==============
+* examples/run-all-ex.sh does not work on Cygwin. (NAF - 2011/02/11)
+
+* Parallel test, t_shapesame in testpar, is rather unstable as it continues to
+ have occasional errors in AIX and quite often in NCSA Abe. It is being built
+ but it is not run automatically in the "make check" command. One would have to
+ run it by hand to see if it works in a particular machine. AKC - 2011/01/28
+
+* Although OpenVMS Alpha is supported, there are several problems with the C
+ test suite - getname.c, lheap.c, lheap.c, mtime.c, and stab.c. The test
+ suite for h5diff also fails. These failures are from the tests, not the
+ library. We have fixed these failures. But it's too late to put the fixes
+ into this release. If you install the 1.8.6 library, it should still work
+ despite of these test failures. If you want the working copy without any
+ test failure, you can request it from us. SLU - 2011/01/26
+
+* If parallel gmake (e.g., gmake -j 4) is used, the "gmake clean" command
+ sometimes fails in the perform directory due to the attempt to remove the
+ executable of h5perf or h5perf_serial by two "parallel" commands. This error
+ has no consequence on the functionality of the HDF5 library or install. It
+ is fixed in the next release. AKC - 2011/01/25
+
+* 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 filesystems.
+
+ 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/
+
+* The h5diff tool can display garbage values when variable-length strings in
+ a compound type dataset are compared. This also occurs with variable-length
+ string arrays in a compound type dataset. See bug #1989. This will be fixed
+ in the next release. JKM - 2010/11/05
+
+* The AIX --enable-shared setting does not quite work. It can produce a shared
+ library, but there cannot be more than one shared library that is
+ interlinked. This means that the high level APIs will not work which is not
+ very useful. We hope to have a solution in the next release.
+ (AKC - 2010/10/15)
+
+* H5Eset_auto can cause a seg fault for a library API call if the application
+ compiles with -DH5_USE_16_API (see bug 1707). It will be fixed in the
+ next release. SLU - 2010/10/5
+
+* The library's test dt_arith.c showed a compiler's rounding problem on
+ Cygwin when converting an unsigned long long to a long double. The
+ library's own conversion works fine. We defined a macro for Cygwin to
+ skip this test until we can solve the problem. Please see bug #1813.
+ SLU - 2010/5/5
+
+* All the VFL drivers aren't backwardly compatible. In H5FDpublic.h, the
+ structure H5FD_class_t changed in 1.8. A new parameter was added to the
+ get_eoa and set_eoa callback functions, and a new callback function
+ get_type_map was added. 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 a 1.8 library. This will be fixed in 1.10. SLU - 2010/2/2
+
+* MinGW has a missing libstdc++.dll.a library file and will not successfully link
+ C++ applications/tests. Do not use the enable-cxx configure option. Read all of
+ the INSTALL_MINGW.txt file for all restrictions. ADB - 2009/11/11
+
+* The PathScale MPI implementation, accessing a Panasas file system, would
+ cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file does not
+ exist. This is due to the MPI_File_open() call failing if the amode has
+ the MPI_MODE_EXCL bit set. (See bug 1468 for details.) AKC - 2009/8/11
+
+* 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
+
+* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh and
+ tools/h5copy/testh5copy.sh will fail some of their sub-tests. These
+ sub-tests are expected to fail and should exit with a non-zero code but
+ the yod command does not propagate the exit code of the executables. Yod
+ always returns 0 if it can launch the executable. The test suite shell
+ expects a non-zero for this particular test. Therefore, it concludes the
+ test has failed when it receives 0 from yod. To skip all the "failing"
+ tests for now, change them as shown below.

+ ==================================================
+ AKC - 2008/11/10
+
+* For Red Storm, a Cray XT3 system, the yod command sometimes gives the
+ message "yod allocation delayed for node recovery." This interferes
+ with test suites that do not expect to see this message. See the "Red Storm"
+ section in file INSTALL_parallel for a way to deal with this problem.
+ AKC - 2008/05/28
+
+* On an Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers,
+ use the -mp -O1 compilation flags to build the libraries. A higher level
+ of optimization causes failures in several HDF5 library tests.
+
+* On mpich 1.2.5 and 1.2.6 on a system using four processors, if more than
+ two processes contribute no I/O and the application asks to do collective
+ I/O, we have found that a simple collective write will sometimes hang. This
+ can be verified with the t_mpi test under testpar.
+
+* A dataset created or rewritten with a v1.6.3 or later library cannot be
+ read with the v1.6.2 or earlier library when the Fletcher32 EDC filter
+ is enabled. There was a bug in the calculation of the Fletcher32 checksum
+ in the library before v1.6.3; the checksum value was not consistent
+ between big-endian and little-endian systems. This bug was fixed in
+ Release 1.6.3. However, after fixing the bug, the checksum value was no
+ longer the same as before on little-endian system. Library releases after
+ 1.6.4 can still read datasets created or rewritten with an HDF5 library of
+ v1.6.2 or earlier. SLU - 2005/6/30
+
+* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
+ messages like "INFO: 0031-XXX ...". This is from the command `poe'. To
+ work around this, set the environment variable MP_INFOLEVEL to 0 to
+ minimize the messages and run the tests again. The tests may fail with
+ messages like "The socket name is already in use", but HDF5 does not use
+ sockets. This failure is due to problems with the poe command trying to
+ set up the debug socket. To resolve this problem, check to see whether
+ there are any old /tmp/s.pedb.* files around. These are sockets used by
+ the poe command and left behind if the command failed at some point. To
+ resolve this, ask your system administrator to remove the
+ old/tmp/s.pedb.* files, and then ask IBM to provide a means to run poe
+ without the debug socket.
+
+* 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.
+
+* On an SGI Altix SMP ia64 system, the Intel compiler version 10.1 (which
+ is the default on that system) does not work properly and results in
+ failures during the make check (in a static build) and the make
+ installcheck (in a shared build). This appears to be a compiler
+ optimization problem. Reducing the optimization by setting CFLAGS to
+ -O1 or below resolves the issue. Using a newer version of the compiler
+ (11.0) avoids the issue. MAM - 2010/06/01
+
+* On solaris systems, when running the examples with the scripts installed in
+ .../share/hdf5_examples, two of the c tests, h5_extlink and h5_elink_unix2win
+ may fail or generate HDF5 errors because the script commands in c/run-c-ex.sh
+ fail to create test directories red, blue, and u2w. Moving the '!' in lines
+ 67, 70, 73 of run-c-ex.sh will fix the problem. For example the script command
+ "if ! test -d red; then" will work on solaris if changed to
+ "if test ! -d red; then".

+- New Features
+- Support for New Platforms, Languages, and Compilers
+- Bug Fixes since HDF5-1.8.4
+- Platforms Tested
+- Supported Configuration Features Summary
+- Known Problems
+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - CMake Early Access: This release adds support for building HDF5 using
+ the CMake system. Initial work has targeted Windows, but other platforms
+ can be used. See the CMake.TXT file for more information. Version
+ 2.8.1 of CMake is required.
+ - Configure now adds appropriate defines for supporting large (64-bit)
+ files on all systems, where supported, by default, instead of only Linux.
+ This large file support is controllable with the --enable-largefile
+ configure option. The Linux-specific --enable-linux-lfs option has been
+ deprecated in favor of this new option. Please note that specifying
+ --disable-large does NOT attempt to "turn off" largefile support if it
+ is natively supported by the compiler, but rather just disables
+ configure from actively trying to add any additional compiler flags.
+ (MAM - 2010/05/05 - Bug # 1772/1434)
+ - Fixed an signal handling mask error in H5detect that might result in
+ SIGBUS or SIGSEGV failures in some platforms such as Linux on Sparc.
+ (AKC - 2010/4/28 - Bug # 1764)
+ - Fixed various "strict aliasing" problems, allowing higher levels
+ of compiler optimization (in particular, allowing '-O3' to work
+ with recent versions of GCC). (QAK - 2010/04/26)
+ - Upgraded versions of autotools used to generate configuration suite.
+ We now use Automake 1.11.1, Autoconf 2.65, and Libtool 2.2.6b.
+ (MAM - 2010/04/15)
+ - Added the xlc-* and mpcc_r-* BASENAME patterns to be recognized as IBM
+ compilers so that the IBM compiler options can be added properly. This
+ allows non-system-default compiler command names (e.g. xlc-m.n.k.l) be
+ recognized. (AKC - 2009/11/26)
+
+ Library
+ -------
+ - Performance is substantially improved when extending a dataset with early
+ allocation. (NAF - 2010/03/24 - Bug # 1637)
+ - Added support for filtering densely stored groups. Many of the API
+ functions related to filters have been extended to support dense groups
+ as well as datasets. Pipeline messages can now be stored in a group's
+ object header. (NAF/QAK - 2009/11/3)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5dump: Added the new packed bits feature which prints packed bits stored
+ in an integer dataset. (AKC/ADB - 2010/5/7)
+ - h5diff: Fixed incorrect behavior (hang) in parallel mode when specifying
+ invalid options (ex: -v and -q). (JKM - 2010/02/17)
+ - h5diff: Added new flag --no-dangling-links (see --help for details).
+ (JKM - 2010/02/10)
+ - h5diff: Added new flag --follow-symlinks (see --help for details).
+ (JKM - 2010/01/25)
+ - h5diff: Added a fix to correct the display of garbage values when
+ displaying big-endian data on a little-endian machine. (JKM - 2009/11/20)
+
+ High-Level APIs
+ ---------------
+ - None
+
+ F90 API
+ -------
+ - None
+
+ C++ API
+ -------
+ - New member functions
+ + Overloaded CommonFG::getObjnameByIdx to take char* for name.
+ + Overloaded CommonFG::getObjTypeByIdx to return type name as a char*.
+ (BMR - 2010/05/10)
+ + Added DataSet::getInMemDataSize() to simplify getting the dataset's
+ data size in memory. (BMR - 2009/07/26)
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - AIX 6.1 has been added. (AKC - 2010/1/4)
+
+
+Bug Fixes since HDF5-1.8.4
+==========================
+
+ Configuration
+ -------------
+ - Fixed various "strict aliasing" problems, allowing higher levels
+ of compiler optimization (in particular, allowing '-O3' to work
+ with recent versions of GCC). (QAK - 2010/04/26)
+
+ Library
+ -------
+ - Fixed a file corruption bug that could happen when shrinking a compressed
+ dataset. (NAF - 2010/05/20)
+ - Fixed some memory leaks in VL datatype conversion when strings are
+ used as fill values. (MAM - 2010/05/12 - Bug # 1826)
+ - Fixed an H5Rcreate failure when passing in a -1 for the dataspace
+ identifier. (ADB - 2010/4/28)
+ - Fixed a bug when copying objects with NULL references with the
+ H5O_COPY_EXPAND_REFERENCE_FLAG flag set. (NAF - 2010/04/08 - Bug # 1815)
+ - Added a mechanism to the H5I interface to save returned object identifier
+ structures for immediate re-use if needed. This addresses a potential
+ performance issue by delaying the case when the next identifier to be
+ registered has grown so large that it wraps around and needs to be
+ checked to see whether it is available for distribution.
+ (MAM - 2010/03/15 - Bug # 1730)
+ - Files can now be concurrently opened more than once using the core file
+ driver, as long as the backing store is used. (NAF - 2010/03/09)
+ - Added support for H5O_COPY_EXPAND_EXT_LINK_FLAG to H5Ocopy. External
+ links will now be expanded if this flag is set.
+ (NAF - 2010/03/05 - Bug # 1733)
+ - Fixed a bug where the library, when traversing an external link, would
+ reopen the source file if nothing else worked. (NAF - 2010/03/05)
+ - Fixed a bug where fractal heap identifiers for attributes and shared
+ object header messages could be incorrectly encoded in the file for
+ files created on big-endian platforms.
+ Please see http://www.hdfgroup.org/HDF5/release/known_problems if you
+ suspect you have a file with this problem.
+ (QAK - 2010/02/23 - Bug # 1755)
+ - Fixed an intermittent bug in the b-tree code which could be triggered
+ by expanding and shrinking chunked datasets in certain ways.
+ (NAF - 2010/02/16)
+ - H5Tdetect_class said a VL string is a string type. But when it's in
+ a compound type, it said it's a VL type. THis has been fixed to be
+ consistent; it now always returns a string type.
+ (SLU - 2009/12/10 - Bug # 1584)
+ - Allow "child" files from external links to be correctly located when
+ relative to a "parent" file that is opened through a symbolic link.
+ (QAK - 2009/12/01)
+
+ Parallel Library
+ ----------------
+ - Parallel mode in AIX will fail some of the testcheck_version.sh tests
+ where it treats "exit(134) the same as if process 0 had received an abort
+ signal. Fixed. (AKC - 2009/11/3)
+
+ Tools
+ -----
+ - Fixed h5ls to return exit code 1 (error) when a non-existent file is
+ specified. (JKM - 2010/04/27 - Bug # 1793)
+ - Fixed h5copy failure when copying a dangling link that is specified
+ directly. (JKM - 2010/04/22 - Bug # 1817)
+ - Fixed an h5repack failure that lost attributes from a dataset of
+ reference type. (JKM - 2010/3/25 - Bug # 1726)
+ - Fixed h5repack error that set NULL for object reference values for
+ datasets, groups, or named datatypes. (JKM - 2010/03/19 - Bug # 1814)
+
+ F90 API
+ ------
+ - None
+
+ C++ API
+ ------
+ - The constructor PropList::PropList(id) was fixed to act properly
+ according to the nature of 'id'. When 'id' is a property class
+ identifier, a new property list will be created. When 'id' is a
+ property list identifier, a copy of the property list will be made.
+ (BMR - 2010/5/9)
+ - The parameters 'size' and 'bufsize' in CommonFG::getLinkval and
+ CommonFG::getComment, respectively, now have default values for the
+ user's convenience. (BMR - 2009/10/23)
+ - NULL pointer accessing was fixed. (BMR - 2009/10/05 - Bug # 1061)
+ - Read/write methods of DataSet and Attribute classes were fixed
+ to handle string correctly. (BMR - 2009/07/26)
+
+ High-Level APIs:
+ ------
+ - Fixed a bug in H5DSattach_scale, H5DSis_attached, and H5DSdetach_scale
+ caused by using the H5Tget_native_type function to determine the native
+ type for reading the REFERENCE_LIST attribute. This bug was exposed
+ on Mac PPC. (EIP - 2010/05/22 - Bug # 1851)
+ - Fixed a bug in the H5DSdetach_scale function when 0 bytes were
+ allocated after the last reference to a dimension scale was removed
+ from the list of references in a VL element of the DIMENSION_LIST
+ attribute. Modified the function to comply with the specification:
+ the DIMENSION_LIST attribute is now deleted when no dimension scales
+ are left attached. (EIP - 2010/05/14 - Bug # 1822)
+
+ Fortran High-Level APIs:
+ ------
+ - None
+

+
+
+Known Problems
+==============
+* The library's test dt_arith.c exposed a compiler's rounding problem on
+ Cygwin when converting from unsigned long long to long double. The
+ library's own conversion works correctly. A macro is defined for Cygwin
+ to skip this test until we can solve the problem. (Please see bug #1813.)
+ SLU - 2010/5/5
+
+* All the VFL drivers aren't backward compatible. In H5FDpublic.h, the
+ structure H5FD_class_t changed in 1.8. There is a new parameter added to
+ get_eoa and set_eoa callback functions. A new callback function
+ get_type_map was added. 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 it into a 1.8 library. This affects a very small
+ number of users. (See bug report #1279.) SLU - 2010/2/2
+
+* MinGW has a missing libstdc++.dll.a library file and will not successfully
+ link C++ applications/tests. Do not use the enable-cxx configure option.
+ Read all of the INSTALL_MINGW.txt file for all restrictions.
+ ADB - 2009/11/11
+
+* Some tests in tools/h5repack may fail in AIX systems when -q32 mode is used.
+ The error is due to insufficient memory requested. Request a large amount
+ of runtime memory by setting the following environment variable for more
+ memory.
+ LDR_CNTRL=MAXDATA=0x20000000@DSA
+ AKC - 2009/10/31
+
+* The PathScale MPI implementation, accessing a Panasas file system, would
+ cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file is not
+ existing. This is due to the MPI_File_open() call failing if the amode has
+ the MPI_MODE_EXCL bit set. (See bug 1468 for details.) AKC - 2009/8/11
+
+* 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
+
+* For gcc v4.3 and v4.4, with production mode, if -O3 is used, H5Tinit.c
+ would fail to compile. Actually bad H5Tinit.c is produced. If -O (same
+ as -O1) is used, H5Tinit.c compiled okay but test/dt_arith would fail.
+ When -O0 (no optimizatio) is used, H5Tinit.c compilete okay and all
+ tests passed. Therefore, -O0 is imposed for v4.3 and v4.4 of gcc.
+ AKC - 2009/04/20
+
+* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh and
+ tools/h5copy/testh5copy.sh will fail some of its sub-tests. These sub-tests
+ are expected to fail and should exit with a non-zero code but the yod
+ command does not propagate the exit code of the executables. Yod always
+ returns 0 if it can launch the executable. The test suite shell expects
+ a non-zero for this particular test, therefore it concludes the test has
+ failed when it receives 0 from yod. Skip all the "failing" test for now
+ by changing them as following.
+
+ ======== Original tools/h5ls/testh5ls.sh =========
+ TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5

+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested
+ echo SKIP H5LSTEST $FILEOUT
+ ==================================================
+ AKC - 2008/11/10
+
+* For Red Storm, a Cray XT3 system, the yod command sometimes gives the
+ message, "yod allocation delayed for node recovery". This interferes with
+ test suites that do not expect seeing this message. See the section of "Red
+ Storm" in file INSTALL_parallel for a way to deal with this problem.
+ AKC - 2008/05/28
+
+* On Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers,
+ use -mp -O1 compilation flags to build the libraries. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
+ the application asks to do collective IO, we have found that when using 4
+ processors, a simple collective write will sometimes be hung. This can be
+ verified with t_mpi test under testpar.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+ SLU - 2005/6/30
+
+* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
+ messages like "INFO: 0031-XXX ...". This is from the command `poe'.
+ Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
+ and run the tests again.
+
+ The tests may fail with messages like "The socket name is already in use,"
+ but HDF5 does not use sockets. This failure is due to problems with the
+ poe command trying to set up the debug socket. To resolve this problem,
+ check to see whether there are many old /tmp/s.pedb.* files staying around.
+ These are sockets used by the poe command and left behind due to failed
+ commands. First, ask your system administrator to clean them out.
+ Lastly, request IBM to provide a means to run poe without the debug socket.
+
+* 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.
+
+* There is also a configure error on Altix machines that incorrectly reports
+ when a version of Szip without an encoder is being used.
+
+* On FREE-BSD systems when shared libraries are disabled, make install fails
+ in install-examples with the error '"Makefile", line 635: Need an operator'.
+ When this error occurs removing or commenting out the line "export
+ LD_LIBRARY_PATH=$(LL_PATH)" (line 635 in examples/Makefile) will allow make
+ install to finish installing examples. The problem will be fixed in the
+ next release. LRK - 2010/05/26
+
+* On cobalt, an SGI Altix SMP ia64 system, Intel compiler version 10.1 (which
+ is the default on that system) does not work properly and results in
+ failures during make check (in a static build) and make installcheck (during
+ a shared build). This appears to be a compiler optimization problem.
+ Reducing optimization by setting CFLAGS to -O1 or below resolves the issue.
+ Alternatively, using a newer version of the compiler (11.0) also works as
+ intended. MAM - 2010/06/01

+- New Features
+- Support for New Platforms, Languages, and Compilers
+- Bug Fixes since HDF5-1.8.3
+- Platforms Tested
+- Supported Configuration Features Summary
+- Known Problems
+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - Configuration suite now uses Automake 1.11 and Autoconf 2.64.
+ MAM 2009/08/31.
+ - Changed default Gnu fortran compiler from g95 to gfortran since
+ gfortran is more likely installed with gcc now. -AKC 2009/07/19-
+
+ Library
+ -------
+ - The embedded library information is displayed by H5check_version() if a
+ version mismatch is detected. Also changed H5check_version() to
+ suppress the warning message totally if $HDF5_DISABLE_VERSION_CHECK is 2
+ or higher. (Old behavior treated 3 or higher the same as 1, that is
+ print a warning and allows the program to continue. (AKC - 2009/9/28)
+ - If a user does not care for the extra library information insert
+ in the executables, he may turn it off by --disable-embedded-libinfo
+ during configure. (AKC - 2009/9/15)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5diff: h5diff treats two INFINITY values different. Fixed by checking
+ (value==expect) before call ABS(...) at h5diff_array.c. This will make
+ that (INF==INF) is true (INF is treated as an number instead of NaN)
+ (PC -- 2009/07/28)
+ - h5diff: add option "--use-system-epsilon" to print difference if
+ (|a-b| > EPSILON).
+ Change default to use strict equality (PC -- 2009/09/12)
+
+ High-Level APIs
+ ---------------
+ - None
+
+ F90 API
+ -------
+ - Added H5Oopen_by_addr_f MSB - 9/14/09
+
+ C++ API
+ -------
+ - None
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - PathScale compilers are recognized and can build the HDF5 library
+ properly. AKC - 2009/7/28 -
+
+
+Bug Fixes since HDF5-1.8.3
+==========================
+
+ Configuration
+ -------------
+ - Removed the following config files, as we no longer support them:
+ config/dec-osf*, config/hpux11.00, config/irix5.x,
+ config/powerpc-ibm-aix4.x config/rs6000-ibm-aix5.x config/unicos*
+ MAM - 2009/10/08
+ - Modified configure and make process to properly preserve user's CFLAGS
+ (and company) environment variables. Build will now properly use
+ automake's AM_CFLAGS for any compiler flags set by the configure
+ process. Configure will no longer modify CFLAGS directly, nor will
+ setting CFLAGS during make completely replace what configure has set up.
+ MAM - 2009/10/08
+ - Support for TFLOPS, config/intel-osf1, is removed since the TFLOPS
+ machine has long retired. AKC - 2009/10/06.
+ - Added $(EXEEXT) extension to H5detect when it's executed in the
+ src/Makefile to generate H5Tinit.c so it works correctly on platforms
+ that require the full extension when running executables.
+ MAM - 2009/10/01 - BZ #1613
+ - Configure will now set FC and CXX to "no" when fortran and c++
+ are not being compiled, respectively, so configure will not run
+ some of the compiler tests for these languages when they are not
+ being used. MAM - 2009/10/01
+ - The --enable-static-exec flag will now properly place the -static flag
+ on the link line of all installed executables. This will force the
+ executable to link with static libraries over shared libraries, provided
+ the static libraries are available. MAM - 2009/08/31 - BZ #1583
+ - The PathScale compiler (v3.2) was mistaken as gcc v4.2.0 but it fails to
+ recognize some gcc options. Fixed. (see bug 1301). AKC - 2009/7/28 -
+
+ Library
+ -------
+ - Fixed a bug where writing and deleting many global heap objects (i.e.
+ variable length data) would render the file unreadable. Previously
+ created files exhibiting this problem should now be readable.
+ NAF - 2009/10/27 - 1483
+ - Fixed error in library's internal caching mechanisms which could cause
+ an assertion failure (and attendent core dump) when encountering an
+ unusually formatted file. (QAK - 2009/10/13)
+ - Fixed incorrect return value for H5Pget_preserve. AKC - 2009/10/08 - 1628
+ - Fixed an assertion failure that occurred when H5Ocopy was called on a
+ dataset using a vlen inside a compound. NAF - 2009/10/02 - 1597
+ - Fixed incorrect return value for H5Pget_filter_by_id1/2 in H5Ppublic.h.
+ NAF - 2009/09/25 - 1620
+ - Fixed a bug where properties weren't being compared with the registered
+ compare callback. NAF - 2009/09/25 - 1555
+ - Corrected problem where library would re-write the superblock in a file
+ opened for R/W access, even when no changes were made to the file.
+ (QAK - 2009/08/20, Bz#1473)
+ - Fixed a bug where H5Pget_filter_by_id would succeed when called for a
+ filter that wasn't present. NAF - 2009/06/25 - 1250
+ - Fixed an issue with committed compound datatypes containing a vlen. Also
+ fixed memory leaks involving committed datatypes. NAF - 2009/06/10 - 1593
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5dump/h5ls display buffer resize fixed in tools library.
+ ADB - 2009/7/21 - 1520
+ - perf_serial test added to Windows projects and check batch file.
+ ADB - 2009/06/11 -1504
+
+
+ F90 API
+ ------
+ - Fixed bug in h5lget_info_by_idx_f by adding missing arguments,
+ consequently changing the API. New API is:
+
+ SUBROUTINE h5lget_info_by_idx_f(loc_id, group_name, index_field, order, n, &
+ link_type, f_corder_valid, corder, cset, address, val_size, hdferr, lapl_id)
+
+ MSB - 2009/9/17 - 1652
+
+ - Corrected the values for the H5L_flags FORTRAN constants:
+ H5L_LINK_ERROR_F, H5L_LINK_HARD_F, H5L_LINK_SOFT_F, H5L_LINK_EXTERNAL_F
+ MSB - 2009-09-17 - 1653
+
+ - Added FORTRAN equivalent of C constant H5T_ORDER_NONE: H5T_ORDER_NONE_F
+ MSB - 2009-9-24 - 1471
+
+ C++ API
+ ------
+ - None
+
+ High-Level APIs:
+ ------
+ - Fixed a bug where the H5TB API would forget the order of fields when added
+ out of offset order. NAF - 2009/10/27 - 1582
+ - H5DSis_attached failed to account for different platform types. Added a
+ get native type call. ADB - 2009/9/29 - 1562
+
+ Fortran High-Level APIs:
+ ------
+ - Lite: the h5ltread_dataset_string_f and h5ltget_attribute_string_f functions
+ had memory problems with the g95 fortran compiler. (PVN � 5/13/2009) 1522

+
+Known Problems
+==============
+* Parallel mode in AIX will fail some of the testcheck_version.sh tests where
+ it treats "exit(134) the same as if process 0 had received an abort signal.
+ This is fixed and will be available in the next release. AKC - 2009/11/3
+
+* Some tests in tools/h5repack may fail in AIX systems when -q32 mode is used.
+ The error is due to insufficient memory requested. Request a large amount
+ of runtime memory by setting the following environment variable for more
+ memory.
+ LDR_CNTRL=MAXDATA=0x20000000@DSA
+ AKC - 2009/10/31
+
+* The PathScale MPI implementation, accessing a Panasas file system, would
+ cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file is not
+ existing. This is due to the MPI_File_open() call failing if the amode has
+ the MPI_MODE_EXCL bit set. (See bug 1468 for details.) AKC - 2009/8/11
+
+* 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
+
+* There is a known issue in which HDF5 will change the timestamp on a file
+ simply by opening it with read/write permissions, even if the file is not
+ modified in any way. This is due to the way in which HDF5 manages the file
+ superblock. A fix is currently underway and should be included in the 1.8.4
+ release of HDF5. MAM - 2009/04/28
+
+* For gcc v4.3 and v4.4, with production mode, if -O3 is used, H5Tinit.c
+ would fail to compile. Actually bad H5Tinit.c is produced. If -O (same
+ as -O1) is used, H5Tinit.c compiled okay but test/dt_arith would fail.
+ When -O0 (no optimizatio) is used, H5Tinit.c compilete okay and all
+ tests passed. Therefore, -O0 is imposed for v4.3 and v4.4 of gcc.
+ AKC - 2009/04/20
+
+* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh and
+ tools/h5copy/testh5copy.sh will fail some of its sub-tests. These sub-tests
+ are expected to fail and should exit with a non-zero code but the yod
+ command does not propagate the exit code of the executables. Yod always
+ returns 0 if it can launch the executable. The test suite shell expects
+ a non-zero for this particular test, therefore it concludes the test has
+ failed when it receives 0 from yod. Skip all the "failing" test for now
+ by changing them as following.
+
+ ======== Original tools/h5ls/testh5ls.sh =========
+ TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5
+ ======== Change to ===============================
+ echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5
+ ==================================================
+
+ ======== Original tools/h5copy/testh5copy.sh =========
+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename
+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets
+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets
+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested

+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets
+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested
+ echo SKIP H5LSTEST $FILEOUT
+ ==================================================
+ AKC - 2008/11/10
+
+* For Red Storm, a Cray XT3 system, the yod command sometimes gives the
+ message, "yod allocation delayed for node recovery". This interferes with
+ test suites that do not expect seeing this message. See the section of "Red
+ Storm" in file INSTALL_parallel for a way to deal with this problem.
+ AKC - 2008/05/28
+
+* On Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers,
+ use -mp -O1 compilation flags to build the libraries. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
+ the application asks to do collective IO, we have found that when using 4
+ processors, a simple collective write will sometimes be hung. This can be
+ verified with t_mpi test under testpar.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+ SLU - 2005/6/30
+
+* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
+ messages like "INFO: 0031-XXX ...". This is from the command `poe'.
+ Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
+ and run the tests again.
+
+ The tests may fail with messages like "The socket name is already in use",
+ but HDF5 does not use sockets. This failure is due to problems with the
+ poe command trying to set up the debug socket. To resolve this problem,
+ check to see whether there are many old /tmp/s.pedb.* files staying around.
+ These are sockets used by the poe command and left behind due to failed
+ commands. First, ask your system administrator to clean them out.
+ Lastly, request IBM to provide a means to run poe without the debug socket.
+
+* 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.
+
+* There is also a configure error on Altix machines that incorrectly reports
+ when a version of Szip without an encoder is being used.

+
+- New Features
+- Support for New Platforms, Languages, and Compilers
+- Bug Fixes since HDF5-1.8.2
+- Platforms Tested
+- Supported Configuration Features Summary
+- Known Problems
+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - Added libtool version numbers to generated c++, fortran, and
+ hl libraries. MAM 2009/04/19.
+ - Regenerated Makefile.ins using Automake 1.10.2. MAM 2009/04/19.
+ - Added a Make target of check-all-install to test the correctness of
+ installing via the prefix= or $DESTDIR options. AKC - 2009/04/14
+
+ Library
+ -------
+ - Embed the content of libhdf5.settings into the hdf5 executables
+ so that an "orphaned" executables can display (via the Unix
+ strings command, for example) the library settings used to build
+ the executables. This is a prototype implementation. Improvement will
+ be added in next release. AKC - 2009/04/20
+ - Separated "factory" free list class from block free lists. These free
+ lists are dynamically created and manage blocks of a fixed size.
+ H5set_free_list_limits() will use the same settings specified for block
+ free lists for factory free lists. NAF - 2009/04/08
+ - Added support for dense attributes to H5Ocopy. XCao/NAF - 2009/01/29
+ - Added H5Pset_elink_cb and H5Pget_elink_cb functions to support a
+ user-defined callback function for external link traversal.
+ NAF - 2009/01/08
+ - Added H5Pset_elink_acc_flags and H5Pget_elink_acc_flags functions to
+ allow the user to specify the file access flags used to open the target
+ file of an external link. NAF - 2009/01/08
+ - Added H5Pset_chunk_cache() and H5Pget_chunk_cache() functions to allow
+ individual rdcc configuration for each dataset. Added
+ H5Dget_access_plist() function to retrieve a dataset access property
+ list from a dataset. NAF - 2008/11/12
+ - Added H5Iis_valid() function to check if an id is valid without
+ producing an error message. NAF - 2008/11/5
+ - Added code to maintain a min_clean_fraction in the metadata cache when
+ in serial mode. MAM - 2009/01/9
+
+ Parallel Library
+ ----------------
+ - Modified parallel tests to run with arbitrary number of processes. The
+ modified tests are testphdf5 (parallel dataset access), t_chunk_alloc
+ (chunk allocation), and t_posix_compliant (posix compliance). The rest of
+ the parallel tests already use in the code the number of processes
+ available in the communicator. (CMC - 2009/04/28)
+
+ Tools
+ -----
+ - h5diff new flag, -c, --compare, list objects that are not comparable.
+ PVN - 2009/4/2 - 1368
+ - h5diff new flag, -N, --nan, avoids NaNs detection. PVN - 2009/4/2
+ - h5dump correctly specifies XML dtd / schema urls ADB - 2009/4/3 - 1519
+ - h5repack now handles group creation order. PVN - 2009/4/2 - 1402
+ - h5repack: When user doesn't specify a chunk size, h5repack now
+ defines a default chunk size as the same size of the size of the
+ hyperslab used to read the chunks. The size of the hyperslabs are
+ defined as the size of each dimension or a predefined constant,
+ whatever is smaller. This assures that the chunk read fits in the
+ chunk cache. PVN - 2008/11/21
+
+ High-Level APIs
+ ---------------
+ - Table: In version 3.0 of Table, the writing of the "NROWS" attribute
+ (used to store number of records) was deprecated. PVN - 2008/11/24
+
+ F90 API
+ -------
+ - Added for the C APIs the Fortran wrappers:
+ h5dget_access_plist_f
+ h5iis_valid_f
+ h5pset_chunk_cache_f
+ h5pget_chunk_cache_f
+ MSB - 2009/04/17
+
+ C++ API
+ -------
+ - None
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+
+
+Bug Fixes since HDF5-1.8.2
+==========================
+
+ Configuration
+ -------------
+ - The --includedir=DIR configuration option now works as intended, and
+ can be used to specify the location to install C header files. The
+ default location remains unchanged, residing at ${prefix}/include.
+ MAM - 2009/03/10 - BZ #1381
+ - Configure no longer removes the '-g' flag from CFLAGS when in production
+ mode if it has been explicitly set in the CFLAGS environment variable
+ prior to configuration. MAM - 2009/03/09 - BZ #1401
+
+ Library
+ -------
+ - Added versioning to H5Z_class_t struct to allow compatibility with 1.6
+ API. NAF - 2009/04/20 - 1533
+ - Fixed a problem with using data transforms with non-native types in the
+ file. NAF - 2009/04/20 - 1548
+ - Added direct.h include file to windows section of H5private.h
+ to fix _getcwd() warning. ADB - 2009/04/14 - 1536
+ - Fixed a bug that prevented external links from working after calling
+ H5close(). NAF - 2009/04/10 - 1539
+ - Modified library to write cached symbol table information to the
+ superblock, to allow library versions 1.3.0 to 1.6.3 to read files created
+ by this version. NAF - 2009/04/08 - 1423
+ - Changed skip lists to use a deterministic algorithm. The library should
+ now never call rand() or srand(). NAF - 2009/04/08 - 503
+ - Fixed a bug where H5Lcopy and H5Lmove wouldn't create intermediate groups
+ when that property was set. NAF - 2009/04/07 - 1526
+ - Fixed a bug that caused files with a user block to grow by the size of the
+ user block every time they were opened. NAF - 2009/03/26 - 1499
+ - Fixed a rare problem that could occur with files using the old (pre 1.4)
+ array datatype. NAF - 2009/03/23
+ - Modified library to be able to open files with corrupt root group symbol
+ table messages, and correct these errors if they are found. Such files
+ can only be successfully opened with write access. NAF - 2009/03/23 - 1189
+ - Removed the long_long #define and replaced all instances with
+ "long long". This caused problems with third party products. All
+ currently supported compliers support the type. ADB - 2009/03/05
+ - Fixed various bugs that could prevent the fill value from being written
+ in certain rare cases. NAF - 2009/02/26 - 1469
+ - Fixed a bug that prevented more than one dataset chunk from being cached
+ at a time. NAF - 2009/02/12 - 1015
+ - Fixed an assertion failure caused by opening an attribute multiple times
+ through multiple file handles. NAF - 2009/02/12 - 1420
+ - Fixed a problem that could prevent the user from adding attributes (or any
+ object header message) in some circumstances. NAF - 2009/02/12 - 1427
+ - Fixed a bug that could cause problems when an attribute was added to a
+ committed datatype using the committed datatype's datatype.
+ NAF - 2009/02/12
+ - Fixed a bug that could cause problems when copying an object with a shared
+ message in its own object header. NAF - 2009/01/29
+ - Changed H5Tset_order to properly reject H5T_ORDER_NONE for most datatypes.
+ NAF - 2009/01/27 - 1443
+ - Fixed a bug where H5Tpack wouldn't remove trailing space from an otherwise
+ packed compound type. NAF - 2009/01/14
+ - Fixed up some old v2 btree assertions that get run in debug mode that
+ were previously failing on compilation, and removed some of the
+ more heavily outdated and non-rewritable ones. MAM - 2008/12/15
+ - Fixed a bug that could cause problems when "automatically" unmounting
+ multiple files. NAF - 2008/11/17
+ - H5Dset_extent: when shrinking dimensions, some chunks were not deleted.
+ PVN - 2009/01/8
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - Fixed many problems that could occur when using h5repack with named
+ datatypes. NAF - 2009/4/20 - 1516/1466
+ - h5dump, h5diff, h5repack were not reading (by hyperslabs) datasets
+ that have a datatype datum size greater than H5TOOLS_BUFSIZE, a constant
+ defined as 1024Kb, such as array types with large dimensions.
+ PVN - 2009/4/1 - 1501
+ - h5import: By selecting a compression type, a big endian byte order
+ was being selected. PVN - 2009/3/11 - 1462
+ - zip_perf.c had missing argument on one of the open() calls. Fixed.
+ AKC - 2008/12/9
+
+ F90 API
+ ------
+ - None
+
+ C++ API
+ ------
+ - None
+
+ High-Level APIs:
+ ------
+ - Dimension scales: The scale index return value in H5DSiterate_scales
+ was not always incremented. PVN - 2009/4/8 - 1538
+
+ Fortran High-Level APIs:
+ ------
+ - Lite: The h5ltget_dataset_info_f function (gets information about
+ a dataset) was not correctly returning the dimension array
+ PVN - 2009/3/23

+
+
+Known Problems
+==============
+* 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
+
+* There is a known issue in which HDF5 will change the timestamp on a file
+ simply by opening it with read/write permissions, even if the file is not
+ modified in any way. This is due to the way in which HDF5 manages the file
+ superblock. A fix is currently underway and should be included in the 1.8.4
+ release of HDF5. MAM - 2009/04/28
+
+* For gcc v4.3 and v4.4, with production mode, if -O3 is used, H5Tinit.c
+ would fail to compile. Actually bad H5Tinit.c is produced. If -O (same
+ as -O1) is used, H5Tinit.c compiled okay but test/dt_arith would fail.
+ When -O0 (no optimizatio) is used, H5Tinit.c compilete okay and all
+ tests passed. Therefore, -O0 is imposed for v4.3 and v4.4 of gcc.
+ AKC - 2009/04/20
+
+* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh and
+ tools/h5copy/testh5copy.sh will fail some of its sub-tests. These sub-tests
+ are expected to fail and should exit with a non-zero code but the yod
+ command does not propagate the exit code of the executables. Yod always
+ returns 0 if it can launch the executable. The test suite shell expects
+ a non-zero for this particular test, therefore it concludes the test has
+ failed when it receives 0 from yod. Skip all the "failing" test for now
+ by changing them as following.
+
+ ======== Original tools/h5ls/testh5ls.sh =========
+ TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5
+ ======== Change to ===============================
+ echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5
+ ==================================================
+
+ ======== Original tools/h5copy/testh5copy.sh =========
+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename
+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets
+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets
+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested
+ H5LSTEST $FILEOUT
+ ======== Change to ===============================
+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d grp_rename
+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets
+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets
+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested
+ echo SKIP H5LSTEST $FILEOUT
+ ==================================================
+ AKC - 2008/11/10
+
+* For Red Storm, a Cray XT3 system, the yod command sometimes gives the
+ message, "yod allocation delayed for node recovery". This interferes with
+ test suites that do not expect seeing this message. See the section of "Red
+ Storm" in file INSTALL_parallel for a way to deal with this problem.
+ AKC - 2008/05/28
+
+* We have discovered two problems when running collective IO parallel HDF5
+ tests with chunking storage on the ChaMPIon MPI compiler on tungsten, a
+ Linux cluster at NCSA.
+
+ Under some complex selection cases:
+ 1) MPI_Get_element returns the wrong value.
+ 2) MPI_Type_struct also generates the wrong derived datatype and corrupt
+ data may be generated.
+ These issues arise only when turning on collective IO with chunking storage
+ with some complex selections. We have not found these problems on other
+ MPI-IO compilers. If you encounter these problems, you may use independent
+ IO instead.
+
+ To avoid this behavior, change the following line in your code
+ H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE);
+ to
+ H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT);
+ KY - 2007/08/24
+
+* On Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers,
+ use -mp -O1 compilation flags to build the libraries. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* For LLNL, uP: both serial and parallel tests pass.
+ Zeus: Serial tests pass but parallel tests fail with a known problem in MPI.
+ ubgl: Serial tests pass but parallel tests fail.
+
+* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
+ the application asks to do collective IO, we have found that when using 4
+ processors, a simple collective write will sometimes be hung. This can be
+ verified with t_mpi test under testpar.
+
+* On IRIX6.5, when the C compiler version is greater than 7.4, complicated
+ MPI derived datatype code will work. However, the user should increase
+ the value of the MPI_TYPE_MAX environment variable to some appropriate value
+ to use collective irregular selection code. For example, the current
+ parallel HDF5 test needs to raise MPI_TYPE_MAX to 200,000 to pass the test.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+ SLU - 2005/6/30
+
+* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
+ messages like "INFO: 0031-XXX ...". This is from the command `poe'.
+ Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
+ and run the tests again.
+
+ The tests may fail with messages like "The socket name is already in use",
+ but HDF5 does not use sockets. This failure is due to problems with the
+ poe command trying to set up the debug socket. To resolve this problem,
+ check to see whether there are many old /tmp/s.pedb.* files staying around.
+ These are sockets used by the poe command and left behind due to failed
+ commands. First, ask your system administrator to clean them out.
+ Lastly, request IBM to provide a means to run poe without the debug socket.
+
+* The --enable-static-exec configure flag fails to compile for Solaris
+ platforms. This is due to the fact that not all of the system libraries on
+ Solaris are available in a static format.
+
+ The --enable-static-exec configure flag also fails to correctly compile
+ on IBM SP2 platforms for serial mode. The parallel mode works fine with
+ this option.
+
+ It is suggested that you do not use this option on these platforms
+ during configuration.
+
+* There is also a configure error on Altix machines that incorrectly reports
+ when a version of Szip without an encoder is being used.
+
+* Information about building with PGI and Intel compilers is available in
+ the INSTALL file sections 4.7 and 4.8.

+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - Upgraded libtool to version 2.2.6a. (MAM - 2008/10/15).
+
+ Library
+ -------
+ - Added two new public routines: H5Pget_elink_fapl() and
+ H5Pset_elink_fapl(). (see bug #1247) (VC - 2008/10/13)
+ - Improved free space tracking in file to be faster. (QAK - 2008/10/06)
+ - Added 'mounted' field to H5G_info_t struct. (QAK - 2008/07/15)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5repack: added new options -u and -b to add a userblock to an HDF5
+ file during the repack. (PVN - 2008/08/26)
+ - h5repack: added options -t and -a to call H5Pset_alignment while
+ creating a repacked file. (PVN - 2008/08/29)
+ - h5ls: added capability to traverse through external links when the -r
+ (recursive) flag is given. (NAF - 2008/09/16)
+ - h5ls: added -E option to enable traversal of external links.
+ h5ls will not traverse external links without this flag being set.
+ (NAF - 2008/10/06)
+ - h5dump: when -b flag is used without a keyword after it, binary
+ output defaults to NATIVE. MEMORY keyword was deprecated
+ and replaced by NATIVE keyword. (PVN - 2008/10/30)
+ - h5diff: returns 1 when file graphs differ by any object.
+ Error return code was changed to 2 from -1. (PVN - 2008/10/30)
+ - h5import: TEXTFPE (scientific format) was deprecated. Use TEXTFP
+ instead (PVN - 2008/10/30)
+
+
+
+ F90 API
+ ------
+ - Added optional parameter 'mounted' to H5Gget_info_f,
+ H5Gget_info_by_idx_f, H5Gget_info_by_name_f (MSB - 2008/09/24)
+ - Added H5Tget_native_type_f (MSB - 2008/09/30)
+
+
+ C++ API
+ ------
+ - These member functions were added as wrapper for H5Rdereference to
+ replace the incorrect IdComponent::dereference().
+ void H5Object::dereference(H5Object& obj, void* ref,
+ H5R_type_t ref_type=H5R_OBJECT)
+ void H5Object::dereference(H5File& h5file, void* ref,
+ H5R_type_t ref_type=H5R_OBJECT)
+ void H5Object::dereference(Attribute& obj, void* ref,
+ H5R_type_t ref_type=H5R_OBJECT)
+
+ In addition, these constructors were added to create the associated
+ objects by way of dereference:
+ DataSet(H5Object& obj, void* ref, H5R_type_t ref_type=H5R_OBJECT)
+ DataSet(H5File& file, void* ref, H5R_type_t ref_type=H5R_OBJECT)
+ DataSet(Attribute& attr, void* ref, H5R_type_t ref_type=H5R_OBJECT)
+ Group(H5Object& obj, void* ref, H5R_type_t ref_type=H5R_OBJECT)
+ Group(H5File& obj, void* ref, H5R_type_t ref_type=H5R_OBJECT)
+ Group(Attribute& attr, void* ref, H5R_type_t ref_type=H5R_OBJECT)
+ DataType(H5Object& obj, void* ref, H5R_type_t ref_type=H5R_OBJECT)
+ DataType(H5File& file, void* ref, H5R_type_t ref_type=H5R_OBJECT)
+ DataType(Attribute& attr, void* ref, H5R_type_t ref_type=H5R_OBJECT)
+ (BMR - 2008/10/29)
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - Intel 10.1 is supported on Mac OS X 10.5.4.
+ Note:
+ When Fortran is enabled, configure automatically
+ disables the build of shared libraries (i.e., only
+ static C and C++ HDF5 libraries will be built
+ along with the static HDF5 Fortran library).
+ Intel 10.1 C and C++ compilers require
+ "-no-multibyte-chars" compilation flag due to the known
+ bug in the compilers.
+ (EIP - 2008/10/30)
+
+
+Bug Fixes since HDF5-1.8.1
+==========================
+
+ Configuration
+ -------------
+ - Fixed error with 'make check install' failing due to h5dump
+ needing other tools built first. (MAM - 2008/10/15).
+ - When using shared szip, it is no longer necessary to specify
+ the path to the shared szip libraries in LD_LIBRARY_PATH.
+ (MAM - 2008/10/15).
+ - The file libhdf5_fortran.settings is not installed since its content
+ is included in libhdf5.settings now. (AKC - 2008/10/21)
+ - "make DESTDIR=xxx install" failed to install some tools and files
+ (e.g., h5cc and fortran modules). Fixed. (AKC - 2008/10/8).
+
+ Library
+ -------
+ - H5Ovisit and H5Ovisit_by_name will now properly terminate when the
+ callback function returns a positive value on the starting object.
+ (NAF - 2008/11/03)
+ - Fixed an error where a null message could be created that was larger
+ than could be written to the file. (NAF - 2008/10/23)
+ - Corrected error with family/split/multi VFD not updating driver info
+ when "latest" version of the file format used. (QAK - 2008/10/14)
+ - Corrected alignment+threshold errors to work correctly when metadata
+ aggregation is enabled. (QAK - 2008/10/06)
+ - Changed H5Fget_obj_count and H5Fget_obj_ids to ignore objects
+ registered by the library for internal library use.
+ (NAF - 2008/10/06)
+ - Fixed potential memory leak during compound conversion.
+ (NAF - 2008/10/06)
+ - Changed the return value of H5Fget_obj_count from INT to SSIZE_T.
+ Also changed the return value of H5Fget_obj_ids from HERR_T to
+ SSIZE_T and the type of the parameter MAX_OBJS from INT to SIZE_T.
+ (SLU - 2008/09/26)
+ - Fixed an issue that could cause data to be improperly overwritten
+ during compound type conversion. (NAF - 2008/09/19)
+ - Fixed pointer alignment violations that could occur during vlen
+ conversion. (NAF - 2008/09/16)
+ - Fixed problem where library could cause a segmentation fault when
+ an invalid location ID was given to H5Giterate(). (QAK - 2008/08/19)
+ - Fixed improper shutdown when objects have reference count > 1. The
+ library now tracks reference count due to the application separately
+ from that due to internal library routines. (NAF - 2008/08/19)
+ - Fixed assertion failure caused by incorrect array datatype version.
+ (NAF - 2008/08/08)
+ - Fixed an issue where mount point traversal would fail when using
+ multiple handles for the child. (NAF - 2008/08/07)
+ - Fixed an issue where mount points were inaccessible when using
+ multiple file handles for the parent. The mount table is now in
+ the shared file structure (the parent pointer is still in the
+ top structure). (NAF - 2008/08/07)
+ - Fixed assertion failure caused by incorrect array datatype version.
+ (NAF - 2008/08/04)
+ - Fixed issue where a group could have a file mounted on it twice.
+ (QAK - 2008/07/15)
+ - When an attribute was opened twice and data was written with
+ one of the handles, the file didn't have the data. It happened
+ because each handle had its own object structure, and the empty
+ one overwrote the data with fill value. This is fixed by making
+ some attribute information like the data be shared in the
+ attribute structure. (SLU - 2008/07/07)
+ - Fixed a Windows-specific issue in the ohdr test which was causing
+ users in some timezones to get false errors. This a deficiency in
+ the Windows mktime() function, and has been handled properly.
+ (SJW - 2008/06/19)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5dump now checks for uniqueness of committed datatypes.
+ (NAF - 2008/10/15)
+ - Fixed unnecessary indentation of committed datatypes in h5dump.
+ (NAF - 2008/10/15)
+ - Fixed bugs in h5stat: segmemtation fault when printing groups and
+ print warning message when traversal of objects is unsuccessful.
+ (see bug #1253) (VC- 2008/10/13)
+ - Fixed bug in h5ls that prevented relative group listings (like
+ "h5ls foo.h5/bar") from working correctly (QAK - 2008/06/03)
+ - h5dump: when doing binary output (-b), the stdout printing of
+ attributes was done incorrectly. Removed printing of attributes
+ when doing binary output. (PVN - 2008/06/05)
+
+
+ F90 API
+ ------
+ - h5sselect_elements_f: Added additional operators H5S_SELECT_APPEND
+ and H5S_SELECT_PREPEND (MSB - 2008/09/30)
+ - h5sget_select_elem_pointlist: Fixed list of returned points by
+ rearranging the point list correctly by accounting for C
+ conventions. (MSB - 2008/09/30)
+ - h5sget_select_hyper_blocklist_f: Fixed error in transposed dimension
+ of arrays.(MSB - 2008/9/30)
+ - h5sget_select_bounds_f: Swapped array bounds to account for C and
+ Fortran reversed array notation (MSB - 2008/9/30)
+ - Changed to initializing string to a blank character instead of a
+ null type in tH5P.f90 to fix compiling error using AIX 5.3.0
+ (MSB - 2008/7/29)
+ - Fixed missing commas in H5test_kind.f90 detected by NAG compiler
+ (MSB - 2008/7/29)
+ - Fixed passing and array to a scalar in tH5A_1_8.f90 detected by
+ NAG compiler (MSB - 2008/7/29)
+ - Added the ability of the test programs to use the status of
+ HDF5_NOCLEANUP to determine if the *.h5 files should be removed
+ or not after the tests are completed (MSB - 2008/10/1)
+ - In nh5tget_offset_c: (MSB 9/12/2008)
+ If offset was equal to 0 it returned the error code of -1,
+ this was changed to return an error code of -1 when the offset
+ value is < 0.
+ - Uses intrinsic Fortran function SIZEOF if available when detecting
+ type of INTEGERs and REALs in H5test_kind.f90 (MSB - 2008/9/3)
+ - Put the DOUBLE PRECISION interfaces in a separate module and
+ added a USE statement for the module. The interfaces are
+ included/excluded depending on the state of FORTRAN_DEFAULT_REAL
+ is DBLE_F which detects if the default REAL is DOUBLE PRECISION.
+ This allows the library to be compiled with -r8 Fortran flag
+ without the user needing to edit the source code.
+ (MSB - 200/8/27)
+ - Enable building shared library for fortran by adding the flag -fPIC
+ to the compile flags for versions of Intel Fortran compiler >=9
+ (MSB - 2008/8/26)
+
+ C++ API
+ ------
+ - Fixed a design bug which allowed an Attribute object to create/modify
+ attributes (bugzilla #1068). The API class hierarchy was revised
+ to address the problem. Classes AbstractDS and Attribute are moved
+ out of H5Object. Class Attribute now multiply inherits from
+ IdComponent and AbstractDs and class DataSet from H5Object and
+ AbstractDs. In addition, the data member IdComponent::id was
+ moved into subclasses: Attribute, DataSet, DataSpace, DataType,
+ H5File, Group, and PropList. (BMR - 2008/05/20)
+ - IdComponent::dereference was incorrect and replaced as described
+ in "New Features" section.
+ (BMR - 2008/10/29)

+
+Known Problems
+==============
+* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh and
+ tools/h5copy/testh5copy.sh will fail some of its sub-tests. These sub-tests
+ are expected to fail and should exit with a non-zero code but the yod
+ command does not propagate the exit code of the executables. Yod always
+ returns 0 if it can launch the executable. The test suite shell expects
+ a non-zero for this particular test, therefore it concludes the test has
+ failed when it receives 0 from yod. Skip all the "failing" test for now
+ by changing them as following.
+
+ ======== Original tools/h5ls/testh5ls.sh =========
+ TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5
+ ======== Change to ===============================
+ echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5
+ ==================================================

+ TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested
+ H5LSTEST $FILEOUT
+ ======== Change to ===============================

+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -v -s grp_dsets -d /grp_rename/grp_dsets
+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_dsets -d /E/F/grp_dsets
+ echo SKIP TOOLTEST_FAIL -i $TESTFILE -o $FILEOUT -vp -s /grp_nested -d /G/H/grp_nested
+ echo SKIP H5LSTEST $FILEOUT
+ ==================================================
+ AKC - 2008/11/10
+
+* For Red Storm, a Cray XT3 system, the yod command sometimes gives the
+ message, "yod allocation delayed for node recovery". This interferes with
+ test suites that do not expect seeing this message. See the section of "Red
+ Storm" in file INSTALL_parallel for a way to deal with this problem.
+ AKC - 2008/05/28
+
+* We have discovered two problems when running collective IO parallel HDF5
+ tests with chunking storage on the ChaMPIon MPI compiler on tungsten, a
+ Linux cluster at NCSA.
+
+ Under some complex selection cases:
+ 1) MPI_Get_element returns the wrong value.
+ 2) MPI_Type_struct also generates the wrong derived datatype and corrupt
+ data may be generated.
+ These issues arise only when turning on collective IO with chunking storage
+ with some complex selections. We have not found these problems on other
+ MPI-IO compilers. If you encounter these problems, you may use independent
+ IO instead.
+
+ To avoid this behavior, change the following line in your code
+ H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE);
+ to
+ H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT);
+
+ KY - 2007/08/24
+
+* On Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers,
+ use -mp -O1 compilation flags to build the libraries. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* For LLNL, uP: both serial and parallel tests pass.
+ Zeus: Serial tests pass but parallel tests fail with a known problem in MPI.
+ ubgl: Serial tests pass but parallel tests fail.
+
+* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
+ the application asks to do collective IO, we have found that when using 4
+ processors, a simple collective write will sometimes be hung. This can be
+ verified with t_mpi test under testpar.
+
+* On IRIX6.5, when the C compiler version is greater than 7.4, complicated
+ MPI derived datatype code will work. However, the user should increase
+ the value of the MPI_TYPE_MAX environment variable to some appropriate value
+ to use collective irregular selection code. For example, the current
+ parallel HDF5 test needs to raise MPI_TYPE_MAX to 200,000 to pass the test.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+ SLU - 2005/6/30
+
+* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
+ messages like "INFO: 0031-XXX ...". This is from the command `poe'.
+ Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
+ and run the tests again.
+
+ The tests may fail with messages like "The socket name is already in use",
+ but HDF5 does not use sockets. This failure is due to problems with the
+ poe command trying to set up the debug socket. To resolve this problem,
+ check to see whether there are many old /tmp/s.pedb.* files staying around.
+ These are sockets used by the poe command and left behind due to failed
+ commands. First, ask your system administrator to clean them out.
+ Lastly, request IBM to provide a means to run poe without the debug socket.
+
+* The --enable-static-exec configure flag fails to compile for Solaris
+ platforms. This is due to the fact that not all of the system libraries on
+ Solaris are available in a static format.
+
+ The --enable-static-exec configure flag also fails to correctly compile
+ on IBM SP2 platforms for serial mode. The parallel mode works fine with
+ this option.
+
+ It is suggested that you do not use this option on these platforms
+ during configuration.
+
+* There is also a configure error on Altix machines that incorrectly reports
+ when a version of Szip without an encoder is being used.
+
+* Information about building with PGI and Intel compilers is available in
+ the INSTALL file sections 4.7 and 4.8.

+- Bug Fixes since HDF5-1.8.0
+- Platforms Tested
+- Supported Configuration Features Summary
+- Known Problems
+
+
+New Features
+============
+
+ Configuration
+ -------------
+ - The lib/libhdf5.settings file contains much more configure
+ information. (AKC - 2008/05/18)
+
+ - The new configure option "--disable-sharedlib-rpath" disables
+ embedding the '-Wl,-rpath' information into executables when
+ shared libraries are produced, and instead solely relies on the
+ information in LD_LIBRARY_PATH. (MAM - 2008/05/15)
+
+ - Configuration suite now uses Autoconf 2.61, Automake 1.10.1, and
+ Libtool 2.2.2 (MAM - 2008/05/01)
+
+ Source code distribution
+ ========================
+
+ Library
+ -------
+ - None
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - h5repack: Reinstated the -i and -o command line flags to specify
+ input and output files. h5repack now understands both the old
+ syntax (with -i and -o) and the new syntax introduced in Release
+ 1.8.0. (PVN - 2008/05/23)
+ - h5dump: Added support for external links, displaying the object that
+ an external link points to. (PVN - 2008/05/12)
+ - h5dump: Added an option, -m, to allow user-defined formatting in the
+ output of floating point numbers. (PVN - 2008/05/06)
+ - h5dump, in output of the -p option: Added effective data compression
+ ratio to the dataset storage layout output when a compression filter
+ has been applied to a dataset. (PVN - 2008/05/01)
+
+ F90 API
+ ------
+ New H5A, H5G, H5L, H5O, and H5P APIs to enable 1.8 features were
+ added. See "Release 1.8.1 (current release) versus Release 1.8.0" in
+ the document "HDF5 Software Changes from Release to Release"
+ (http://hdfgroup.org/HDF5/doc/ADGuide/Changes.html) for the
+ complete list of the new APIs.
+
+ C++ API
+ ------
+ - None
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - Both serial and parallel HDF5 are supported for the Red Storm machine
+ which is a Cray XT3 system.
+
+ - The Fortran library will work correctly if compiled with the -i8
+ flag. This has been tested with the g95, PGI and Intel Fortran
+ compilers.
+
+
+Bug Fixes since HDF5-1.8.0
+==========================
+
+ Configuration
+ -------------
+ - None
+
+ Source code distribution
+ ========================
+
+ Library
+ -------
+ - Chunking: Chunks greater than 4GB are disallowed.
+ (QAK - 2008/05/16)
+ - Fixed the problem with searching for a target file when following
+ an external link. The search pattern will depend on whether the
+ target file's pathname is an absolute or a relative path.
+ Please see the H5Lcreate_external description in the "HDF5
+ Reference Manual" (http://hdfgroup.org/HDF5/doc/RM/RM_H5L.html).
+ (VC - 2008/04/08)
+ - Fixed possible file corruption bug when encoding datatype
+ descriptions for compound datatypes whose size was between
+ 256 and 511 bytes and the file was opened with the "use the
+ latest format" property enabled (with H5Pset_libver_bounds).
+ (QAK - 2008/03/13)
+ - Fixed bug in H5Aget_num_attrs() routine to correctly handle an
+ invalid location identifier. (QAK - 2008/03/11)
+
+ Parallel Library
+ ----------------
+ - None
+
+ Tools
+ -----
+ - Fixed bug in h5diff that prevented datasets and attributes with
+ variable-length string elements from comparing correctly.
+ (QAK - 2008/02/28)
+ - Fixed bug in h5dump that caused binary output to be made only for
+ the first dataset, when several datasets were requested.
+ (PVN - 2008/04/07)
+
+ F90 API
+ ------
+ - The h5tset(get)_fields subroutines were missing the parameter to
+ specify a sign position; fixed. (EIP - 2008/05/23)
+ - Many APIs were fixed to work with the 8-byte integers in Fortran vs.
+ 4-byte integers in C. This change is trasparent to user applications.
+
+ C++ API
+ ------
+ - The class hierarchy was revised to address the problem reported
+ in bugzilla #1068, Attribute should not be derived from base
+ class H5Object. Classes AbstractDS was moved out of H5Object.
+ Class Attribute now multiply inherits from IdComponent and
+ AbstractDs and class DataSet from H5Object and AbstractDs.
+ In addition, data member IdComponent::id was moved into subclasses:
+ Attribute, DataSet, DataSpace, DataType, H5File, Group, and PropList.

+
+
+Known Problems
+==============
+* For Red Storm, a Cray XT3 system, the yod command sometimes gives the
+ message, "yod allocation delayed for node recovery". This interferes with
+ test suites that do not expect seeing this message. See the section of "Red
+ Storm" in file INSTALL_parallel for a way to deal with this problem.
+ AKC - 2008/05/28
+
+* For Red Storm, a Cray XT3 system, the tools/h5ls/testh5ls.sh will fail on
+ the test "Testing h5ls -w80 -r -g tgroup.h5" fails. This test is
+ expected to fail and exit with a non-zero code but the yod command does
+ not propagate the exit code of the executables. Yod always returns 0 if it
+ can launch the executable. The test suite shell expects a non-zero for
+ this particular test, therefore it concludes the test has failed when it
+ receives 0 from yod. To bypass this problem for now, change the following
+ lines in the tools/h5ls/testh5ls.sh.
+ ======== Original =========
+ # The following combination of arguments is expected to return an error message
+ # and return value 1
+ TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5
+ ======== Skip the test =========
+ echo SKIP TOOLTEST tgroup-1.ls 1 -w80 -r -g tgroup.h5
+ ======== end of bypass ========
+ AKC - 2008/05/28
+
+* We have discovered two problems when running collective IO parallel HDF5
+ tests with chunking storage on the ChaMPIon MPI compiler on tungsten, a
+ Linux cluster at NCSA.
+
+ Under some complex selection cases:
+ 1) MPI_Get_element returns the wrong value.
+ 2) MPI_Type_struct also generates the wrong derived datatype and corrupt
+ data may be generated.
+ These issues arise only when turning on collective IO with chunking storage
+ with some complex selections. We have not found these problems on other
+ MPI-IO compilers. If you encounter these problems, you may use independent
+ IO instead.
+
+ To avoid this behavior, change the following line in your code
+ H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE);
+ to
+ H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT);
+
+ KY - 2007/08/24
+
+* For SNL, spirit/liberty/thunderbird: The serial tests pass but parallel
+ tests failed with MPI-IO file locking message. AKC - 2007/6/25
+
+* On Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers,
+ use -mp -O1 compilation flags to build the libraries. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* For LLNL, uP: both serial and parallel tests pass.
+ Zeus: Serial tests pass but parallel tests fail with a known problem in MPI.
+ ubgl: Serial tests pass but parallel tests fail.
+
+* Configuring with --enable-debug=all produces compiler errors on most
+ platforms: Users who want to run HDF5 in debug mode should use
+ --enable-debug rather than --enable-debug=all to enable debugging
+ information on most modules.
+
+* On Mac OS 10.4, test/dt_arith.c has some errors in conversion from long
+ double to (unsigned) long long and from (unsigned) long long to long double.
+
+* On Altix SGI with Intel 9.0, testmeta.c would not compile with -O3
+ optimization flag.
+
+* On VAX, the Scaleoffset filter is not supported. The Scaleoffset filter
+ supports only the IEEE standard for floating-point data; it cannot be applied
+ to HDF5 data generated on VAX.
+
+* On Cray X1, a lone colon on the command line of h5dump --xml (as in
+ the testh5dumpxml.sh script) is misinterpereted by the operating system
+ and causes an error.
+
+* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
+ the application asks to do collective IO, we have found that when using 4
+ processors, a simple collective write will sometimes be hung. This can be
+ verified with t_mpi test under testpar.
+
+* On IRIX6.5, when the C compiler version is greater than 7.4, complicated
+ MPI derived datatype code will work. However, the user should increase
+ the value of the MPI_TYPE_MAX environment variable to some appropriate value
+ to use collective irregular selection code. For example, the current
+ parallel HDF5 test needs to raise MPI_TYPE_MAX to 200,000 to pass the test.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculation of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+ SLU - 2005/6/30
+
+* For version 6 (6.02 and 6.04) of the Portland Group compiler on the AMD
+ Opteron processor, there is a bug in the compiler for optimization(-O2).
+ The library failed in several tests, all related to the MULTI driver.
+ The problem has been reported to the vendor.
+
+* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
+ messages like "INFO: 0031-XXX ...". This is from the command `poe'.
+ Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
+ and run the tests again.
+
+ The tests may fail with messages like "The socket name is already in use",
+ but HDF5 does not use sockets. This failure is due to problems with the
+ poe command trying to set up the debug socket. To resolve this problem,
+ check to see whether there are many old /tmp/s.pedb.* files staying around.
+ These are sockets used by the poe command and left behind due to failed
+ commands. First, ask your system administrator to clean them out.
+ Lastly, request IBM to provide a means to run poe without the debug socket.
+
+* The --enable-static-exec configure flag fails to compile for Solaris
+ platforms. This is due to the fact that not all of the system libraries on
+ Solaris are available in a static format.
+
+ The --enable-static-exec configure flag also fails to correctly compile
+ on IBM SP2 platforms for serial mode. The parallel mode works fine with
+ this option.
+
+ It is suggested that you do not use this option on these platforms
+ during configuration.
+
+* With the gcc 2.95.2 compiler, HDF5 uses the `-ansi' flag during
+ compilation. The ANSI version of the compiler complains about not being
+ able to handle the `long long' datatype with the warning:
+
+ warning: ANSI C does not support `long long'
+
+ This warning is innocuous and can be safely ignored.
+
+* The ./dsets tests fail on the TFLOPS machine if the test program,
+ dsets.c, is compiled with the -O option. The HDF5 library still works
+ correctly with the -O option. The test program works fine if it is
+ compiled with -O1 or -O0. Only -O (same as -O2) causes the test
+ program to fail.
+
+* Not all platforms behave correctly with Szip's shared libraries. Szip is
+ disabled in these cases, and a message is relayed at configure time. Static
+ libraries should be working on all systems that support Szip and should be
+ used when shared libraries are unavailable.
+
+ There is also a configure error on Altix machines that incorrectly reports
+ when a version of Szip without an encoder is being used.
+
+* On some platforms that use Intel and Absoft compilers to build the HDF5
+ Fortran library, compilation may fail for fortranlib_test.f90, fflush1.f90
+ and fflush2.f90 complaining about the exit subroutine. Comment out the line
+ IF (total_error .ne. 0) CALL exit (total_error).
+
+* Information about building with PGI and Intel compilers is available in
+ the INSTALL file sections 4.7 and 4.8.
+
+* On at least one system, SDSC DataStar, the scheduler (in this case
+ LoadLeveler) sends job status updates to standard error when you run
+ any executable that was compiled with the parallel compilers.
+
+ This causes problems when running "make check" on parallel builds, as
+ many of the tool tests function by saving the output from test runs,
+ and comparing it to an exemplar.
+
+ The best solution is to reconfigure the target system so it no longer
+ inserts the extra text. However, this may not be practical.
+
+ In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to
+ the configure and build. This will cause "make check" to continue after
+ detecting errors in the tool tests. However, in the case of SDSC DataStar,
+ it also leaves you with some 150 "failed" tests to examine by hand.
+
+ A second solution is to write a script to run serial tests and filter
+ out the text added by the scheduler. A sample script used on SDSC
+ DataStar is given below, but you will probably have to customize it
+ for your installation.
+
+ Observe that the basic idea is to insert the script as the first item
+ on the command line which executes the the test. The script then
+ executes the test and filters out the offending text before passing
+ it on.
+
+ #!/bin/csh
+
+ set STDOUT_FILE=~/bin/serial_filter.stdout
+ set STDERR_FILE=~/bin/serial_filter.stderr
+
+ rm -f $STDOUT_FILE $STDERR_FILE
+
+ ($* > $STDOUT_FILE) >& $STDERR_FILE
+
+ set RETURN_VALUE=$status
+
+ cat $STDOUT_FILE
+
+ tail +3 $STDERR_FILE
+
+ exit $RETURN_VALUE
+
+ You get the HDF5 make files and test scipts to execute your filter script
+ by setting the environment variable "RUNSERIAL" to the full path of the
+ script prior to running configure for parallel builds. Remember to
+ "unsetenv RUNSERIAL" before running configure for a serial build.
+
+ Note that the RUNSERIAL environment variable exists so that we can
+ prefix serial runs as necessary on the target system. On DataStar,
+ no prefix is necessary. However on an MPICH system, the prefix might
+ have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to
+ get the serial tests to run at all.
+
+ In such cases, you will have to include the regular prefix in your
+ filter script.
+
+* H5Ocopy() does not copy reg_ref attributes correctly when shared-message
+ is turn on. The value of the reference in the destination attriubte is
+ wrong. This H5Ocopy problem will affect the h5copy tool.
+
+* In the C++ API, it appears that there are bugs in Attribute::write/read
+ and DataSet::write/read for fixed- and variable-len strings. The problems
+ are being worked on and a patch will be provided when the fixes are
+ available.

+New Features
+============
+
+ HDF5 Release 1.8.0 is a major release with many changes and new features.
+
+ New format and interface features discussed in the "What's New in
+ HDF5 1.8.0" document include the following:
+
+ Enhanced group object management
+ Enhanced attribute management and more efficient meta data handling
+ Expanded datatype features
+ Creation order tracking and indexing
+ Improved meta data caching and cache control
+ UTF-8 encoding
+ New I/O filters: n-bit and scale+offset compression
+ New link (H5L) and object (H5O) interfaces and features
+ External and user-defined links
+ New high-level APIs:
+ HDF5 Packet Table (H5PT) and HDF5 Dimension Scale (H5DS)
+ C++ and Fortran interfaces for older high-level APIs:
+ H5Lite (H5LT), H5Image (H5IM), and H5Table (H5TB)
+ New and improved tools
+ And more...
+
+ http://hdfgroup.org/HDF5/doc/ADGuide/WhatsNew180.html
+
+
+ New APIs associated with these features, other interface changes
+ (e.g., ENUM and struct definitions), and new library configuration flags
+ are listed in the "Release 1.8.0 (current release) versus Release 1.6.x"
+ section of "HDF5 Software Changes from Release to Release."
+
+ http://hdfgroup.org/HDF5/doc/ADGuide/Changes.html
+
+Compatibility
+-------------
+ Many HDF5 users and user communities have existing applications that
+ they may wish to port to Release 1.8.0. Alternatively, some users may
+ wish to take advantage of Release 1.8.0's improved performance without
+ having to port such applications. To facilitate managing application
+ compatibility and porting applications from release to release, the HDF
+ Team has implemented the following features:
+ Individually-configurable macros that selectively map common
+ interface names to the old and new interfaces
+ Library configuration options to configure the macro mappings
+
+ Two related documents accompany this release:
+ "API Compatibility Macros in HDF5" discusses the specifics of the
+ new individually-configurable macros and library configuration
+ options.
+ http://hdfgroup.org/HDF5/doc/RM/APICompatMacros.html
+
+ "New Features in HDF5 Release 1.8.0 and Backward/Forward Format
+ Compatibility Issues" discusses each new feature with regard to
+ its impact on format compatibility.

+Removed Feature
+===============
+The stream virtual file driver (H5FD_STREAM) have been removed in this
+release. This affects the functions H5Pset_fapl_stream and H5Pget_fapl_stream
+and the constant H5FD_STREAM.
+
+This virtual file driver will be available at
+http://hdf5-addons.origo.ethz.ch/. Note that at the time of this release,
+the transition is still in progress; the necessary integration tools may
+not be available when HDF5 Release 1.8.0 first comes out.
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+ - Support for Open VMS 7.3 was added.

+
+Known Problems
+==============
+* We have discovered two problems when running collective IO parallel HDF5
+ tests with chunking storage on the ChaMPIon MPI compiler on tungsten, a
+ Linux cluster at NCSA.
+
+ Under some complex selection cases:
+ 1) MPI_Get_element returns the wrong value.
+ 2) MPI_Type_struct also generates the wrong derived datatype and corrupt
+ data may be generated.
+ These issues arise only when turning on collective IO with chunking storage
+ with some complex selections. We have not found these problems on other
+ MPI-IO compilers. If you encounter these problems, you may use independent
+ IO instead.
+
+ To avoid this behavior, change the following line in your code
+ H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE);
+
+ to
+ H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT);
+
+ KY - 2007/08/24
+
+* For SNL, spirit/liberty/thunderbird: The serial tests pass but parallel
+ tests failed with MPI-IO file locking message. AKC - 2007/6/25
+
+* On Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers,
+ use -mp -O1 compilation flags to build the libraries. A higher level of
+ optimization causes failures in several HDF5 library tests.
+
+* For SNL, Red Storm: Only parallel HDF5 is supported. The serial tests pass
+ when run against the parallel library; the parallel tests also pass, but
+ with lots of non-fatal error messages.
+
+* For LLNL, uP: both serial and parallel tests pass.
+ Zeus: Serial tests pass but parallel tests fail with a known problem in MPI.
+ ubgl: Serial tests pass but parallel tests fail.
+
+* On SUN 5.10 C++, testing fails in the "Testing Shared Datatypes with
+ Attributes" test.
+
+* Configuring with --enable-debug=all produces compiler errors on most
+ platforms: Users who want to run HDF5 in debug mode should use
+ --enable-debug rather than --enable-debug=all to enable debugging
+ information on most modules.
+
+* On Mac OS 10.4, test/dt_arith.c has some errors in conversion from long
+ double to (unsigned) long long and from (unsigned) long long to long double.
+
+* On Altix SGI with Intel 9.0, testmeta.c would not compile with -O3
+ optimization flag.
+
+* On VAX, the Scaleoffset filter is not supported. The filter cannot be
+ applied to HDF5 data generated on VAX. The Scaleoffset filter only supports
+ the IEEE standard for floating-point data.
+
+* On Cray X1, a lone colon on the command line of h5dump --xml (as in
+ the testh5dumpxml.sh script) is misinterpereted by the operating system
+ and causes an error.
+
+* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
+ the application asks to do collective IO, we have found that when using 4
+ processors, a simple collective write will sometimes be hung. This can be
+ verified with t_mpi test under testpar.
+
+* On IRIX6.5, when the C compiler version is greater than 7.4, complicated
+ MPI derived datatype code will work. However, the user should increase
+ the value of the MPI_TYPE_MAX environment variable to some appropriate value
+ to use collective irregular selection code. For example, the current
+ parallel HDF5 test needs to raise MPI_TYPE_MAX to 200,000 to pass the test.
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read
+ with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+ There was a bug in the calculating code of the Fletcher32 checksum in the
+ library before v1.6.3; the checksum value was not consistent between big-
+ endian and little-endian systems. This bug was fixed in Release 1.6.3.
+ However, after fixing the bug, the checksum value was no longer the same as
+ before on little-endian system. Library releases after 1.6.4 can still read
+ datasets created or rewritten with an HDF5 library of v1.6.2 or before.
+ SLU - 2005/6/30
+
+* For version 6 (6.02 and 6.04) of the Portland Group compiler on the AMD
+ Opteron processor, there is a bug in the compiler for optimization(-O2).
+ The library failed in several tests, all related to the MULTI driver.
+ The problem has been reported to the vendor.
+
+* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
+ messages like "INFO: 0031-XXX ...". This is from the command `poe'.
+ Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
+ and run the tests again.
+
+ The tests may fail with messages like "The socket name is already in use",
+ but HDF5 does not use sockets. This failure is due to problems with the
+ poe command trying to set up the debug socket. To resolve this problem,
+ check to see whether there are many old /tmp/s.pedb.* files staying around.
+ These are sockets used by the poe command and left behind due to failed
+ commands. First, ask your system administrator to clean them out.
+ Lastly, request IBM to provide a means to run poe without the debug socket.
+
+* The --enable-static-exec configure flag fails to compile for Solaris
+ platforms. This is due to the fact that not all of the system libraries on
+ Solaris are available in a static format.
+
+ The --enable-static-exec configure flag also fails to correctly compile
+ on IBM SP2 platform for the serial mode. The parallel mode works fine with
+ this option.
+
+ It is suggested that you do not use this option on these platforms
+ during configuration.
+
+* With the gcc 2.95.2 compiler, HDF5 uses the `-ansi' flag during
+ compilation. The ANSI version of the compiler complains about not being
+ able to handle the `long long' datatype with the warning:
+
+ warning: ANSI C does not support `long long'
+
+ This warning is innocuous and can be safely ignored.
+
+* The ./dsets tests fail on the TFLOPS machine if the test program,
+ dsets.c, is compiled with the -O option. The HDF5 library still works
+ correctly with the -O option. The test program works fine if it is
+ compiled with -O1 or -O0. Only -O (same as -O2) causes the test
+ program to fail.
+
+* Not all platforms behave correctly with Szip's shared libraries. Szip is
+ disabled in these cases, and a message is relayed at configure time. Static
+ libraries should be working on all systems that support Szip and should be
+ used when shared libraries are unavailable.
+
+ There is also a configure error on Altix machines that incorrectly reports
+ when a version of Szip without an encoder is being used.
+
+* On some platforms that use Intel and Absoft compilers to build the HDF5
+ Fortran library, compilation may fail for fortranlib_test.f90, fflush1.f90
+ and fflush2.f90 complaining about the exit subroutine. Comment out the line
+ IF (total_error .ne. 0) CALL exit (total_error).
+
+* Information about building with PGI and Intel compilers is available in
+ the INSTALL file sections 4.7 and 4.8.
+
+* On at least one system, SDSC DataStar, the scheduler (in this case
+ LoadLeveler) sends job status updates to standard error when you run
+ any executable that was compiled with the parallel compilers.
+
+ This causes problems when running "make check" on parallel builds, as
+ many of the tool tests function by saving the output from test runs,
+ and comparing it to an exemplar.
+
+ The best solution is to reconfigure the target system so it no longer
+ inserts the extra text. However, this may not be practical.
+
+ In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to
+ the configure and build. This will cause "make check" to continue after
+ detecting errors in the tool tests. However, in the case of SDSC DataStar,
+ it also leaves you with some 150 "failed" tests to examine by hand.
+
+ A second solution is to write a script to run serial tests and filter
+ out the text added by the scheduler. A sample script used on SDSC
+ DataStar is given below, but you will probably have to customize it
+ for your installation.
+
+ Observe that the basic idea is to insert the script as the first item
+ on the command line which executes the the test. The script then
+ executes the test and filters out the offending text before passing
+ it on.
+
+ #!/bin/csh
+
+ set STDOUT_FILE=~/bin/serial_filter.stdout
+ set STDERR_FILE=~/bin/serial_filter.stderr
+
+ rm -f $STDOUT_FILE $STDERR_FILE
+
+ ($* > $STDOUT_FILE) >& $STDERR_FILE
+
+ set RETURN_VALUE=$status
+
+ cat $STDOUT_FILE
+
+ tail +3 $STDERR_FILE
+
+ exit $RETURN_VALUE
+
+ You get the HDF5 make files and test scipts to execute your filter script
+ by setting the environment variable "RUNSERIAL" to the full path of the
+ script prior to running configure for parallel builds. Remember to
+ "unsetenv RUNSERIAL" before running configure for a serial build.
+
+ Note that the RUNSERIAL environment variable exists so that we can
+ can prefix serial runs as necessary on the target system. On DataStar,
+ no prefix is necessary. However on an MPICH system, the prefix might
+ have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to
+ get the serial tests to run at all.
+
+ In such cases, you will have to include the regular prefix in your
+ filter script.
+
+* H5Ocopy() does not copy reg_ref attributes correctly when shared-message
+ is turn on. The value of the reference in the destination attriubte is
+ wrong. This H5Ocopy problem will affect the h5copy tool.
+
