+- 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.

+
+* 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);

+
+* 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.

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
+ - Entry goes here
+ EIP 2009/05/04.
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
+ - None
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)
