+
+New Features
+============
+
+ Configuration:
+ --------------
+ - Removed stream-vfd from the HDF5 library. - AKC 2007/11/19.
+ - Updated versions of autotools. HDF5 now uses automake 1.10.0,
+ autoconf 2.61, and libtool 1.5.22. MAM - 2007/7/25.
+ - Changed default fortran compiler to g95 when gcc is used. - AKC
+ 2007/2/17.
+ - 'make check-vfd' can now be run from the top level directory. Not all
+ tests that 'make check' invokes work with certain Virtual File Drivers,
+ so those tests have been skipped. - MAM 2006/7/17
+ - Added the variable HDF5TestExpress to control how long tests run.
+ Setting it to a value between 0 and 3 controls how thoroughly the
+ library is tested, with 0 being an "exhaustive run" and 3 being a
+ very quick "smoke test." 1 (a "full run") is the default.
+ -JML 2006/6/21
+ - If both shared and static libraries are installed, now both will be
+ tested during 'make install'. -MAM 2006/06/21
+ - Added support to explicity enable stream_vfd or shared libraries
+ when using parallel via the '--enable-stream_vfd' and
+ '--enable-shared' options, respectively. If not explicity defined,
+ These settings default to enabled when parallel is not used,
+ and disabled when parallel is used. -MAM 2006/06/17
+ - Remove the flexible parallel code and the --enable-fphdf5
+ configure option, it was never up to production standards
+ anyway. -QAK 2006/4/20
+ - Added a macro hdf5_mpi_special_collective_io_works to filter out
+ some mpi-io packages that don't support collective IO for no IO
+ contributions in some processes. -KY 2006/2/16
+ - Added -shlib option to link against installed shared libraries to
+ h5c++ and h5fc. -JML 2005/11/1
+ - Added --enable-build-all option to configure, which only developers
+ should need to use. -JML 2005/10/24
+ - Configure uses the 'TR' variable to let the user override the path
+ to the 'tr' utility. -JML 2005/10/17
+ - Configure can recognize -lmpich as a form of MPI library. -AKC-
+ 2005/9/28.
+ - MD5 checksumming has been added to snapshot releases. Release
+ tarballs will be accompanied by .md5 checksum files, which can
+ be verified using the md5sum utility. -JML 2005/9/6
+ - Some configure flags are incompatible (e.g., the C++ APIs cannot
+ be built using the parallel version of HDF5). configure will now
+ output errors when some common incompatible features are used
+ together. -JML 2005/9/6
+ - A new API function, H5Tis_hard(), was added to the library. It
+ checks if a conversion function is a compiler (hard) conversion.
+ SLU - 2005/9/6
+ - t_mpi will run the test_mpio_derived_dtype by default unless it is
+ known not working (indicated by macro H5_MPI_COMPLEX_DERIVED_DATATYPE_WORKS
+ not defined.) -AKC- 2005/8/23.
+ - Test execution has changed in a number of ways:
+ When make is invoked in parallel (using -j), sequential tests
+ are now executed as parallel make targets. This should make them
+ finish more quickly on machines with multiple processors.
+ Since test output is garbled when they are executed by parallel make,
+ tests now dump their output to foo.log files and foo.logsh files
+ (for test scripts). These logs are printed to the screen only
+ when a test fails or when all tests in the current directory have
+ completed successfully.
+ When tests pass, they will create a foo.chkexe file.
+ This prevents the test from executing again until the test or
+ main library changes.
+ All files generated by tests (*.chkexe, *.log, and any *.h5 files
+ created) can be removed by invoking 'make check-clean'.
+ Sequential and parallel library tests can now be invoked separately.
+ 'make check-s' will execute only sequential tests, and 'make check-p'
+ will execute only parallel tests. 'make check' will still execute
+ all tests.
+ -JML 2005/08/03
+ - On windows, all.zip is deprecated. users should
+ read INSTALL_Windows.txt to know the details.
+ Reasons to deprecate all.zip:
+ 1. Avoid confliction for windows programmers
+ 2. Decrease size of CVS tree by adding all.zip
+ 3. Avoid using winzip as the intermediate step
+ --KY 2005/04/22
+ - When HDF5 is created as a shared library, it now uses libtool's
+ shared library versioning scheme. -JML 2005/04/18
+ - HDF5 now uses automake 1.9.5 to generate Makefiles.in.
+ This has a number of effects on users:
+ The Fortran compiler should be set using the environment
+ variable $FC, not $F9X. F9X still works, but is depreciated.
+ The output of make may be different. This should be only a
+ cosmetic effect.
+ make depened (or make dep) is no longer recognized, since automake
+ handles dependency tracking.
+ Some new configure options exist. --enable-dependency-tracking
+ and --disable-dependency-tracking are used to control automake's
+ dependency tracking. Dependencies are on by default *on most
+ platforms and compilers*. If --enable-dependency-tracking is
+ used, they will be enabled on any platform. However, this can
+ slow down builds or even cause build errors in some cases.
+ Likewise, --disable-dependency-tracking can speed up builds and
+ avoid some build errors.
+ Some make targets have alternate names. make check-install and
+ make installcheck do the same thing, for instance.
+ pmake on IRIX can be invoked from the root directory, but the
+ -V flag must be used to invoke it in any subdirectory or it
+ will give an error about undefined variables.
+ JML 2005/01 - 2005/03
+ - Hardware conversion between long double and integers is also added.
+ SLU 2005/02/10
+ - Started to support software conversion between long double and
+ integers. Hardware conversion will come very soon. SLU - 2005/1/6
+ - Intel v8.0 compiler would infinite loop when compiling some test
+ code with -O3 option. Changed enable-production default compiler
+ option to -O2. AKC - 2004/12/06
+ - Long double is assumed to be a supported C data type. It is a
+ stanadard C89 type. AKC - 2004/10/22
+ - The IA64 will use ecc as the C++ compiler by default.
+ - Added some initial support for making valgrind/Purify (or similar
+ memory checking products) happier by initializing buffers to zero
+ and disabling the internal free list code. To take advantage of
+ this, use the "--enable-using-memchecker" configure option when
+ building the library. QAK - 2004/07/23
+ - Fixed the long compile time of H5detect.c when v7.x Intel Compiler
+ is used with optimization NOT off. AKC - 2004/05/20
+ - Fixed configure setting of C++ for OSF1 platform. AKC - 2004/01/06
+ - Prefix default is changed from /usr/local to `pwd`/hdf5.
+ AKC - 2003/07/09
+
+ Library:
+ --------
+ - Removed size restrictions on attributes, when using the "latest"
+ version of the file format. - QAK - 2007/02/21
+ - Relaxed restrictions on attribute operations to allow a file ID to
+ be used as the "location ID". If a file ID is used, the attribute
+ operation will occur on the root group of the file.
+ - QAK - 2007/02/09
+ - Enabled the CORE driver to read an existing file depending on
+ the setting of the backing_store for H5Pset_fapl_core and file
+ open flags. - SLU - 2006/11/30
+ - Added new H5Gget_info_by_idx() routine to query the information about
+ a group according to the order within an index.
+ - QAK - 2006/11/27
+ - Added new H5Gget_info() routine to query the information about a
+ group by name.
+ - QAK - 2006/11/27
+ - Added new H5Oget_info_by_idx() routine to query the information about
+ an object in a group according to the order within an index.
+ - QAK - 2006/11/26
+ - Added new H5Oget_info() routine to query the information about an
+ object in a group by name.
+ - QAK - 2006/11/26
+ - Added new H5Oopen_by_idx() routine to open an object in a group
+ according to the order within an index.
+ - QAK - 2006/11/20
+ - Added new H5Literate() routine to iterate over links in a group
+ according to the order within an index.
+ - QAK - 2006/11/20
+ - Added new H5Ldelete_by_idx() routine to delete a link according to
+ the order within an index.
+ - QAK - 2006/11/13
+ - Added new H5Lget_val_by_idx() routine to query the value of a soft link
+ according to the order within an index.
+ - QAK - 2006/11/13
+ - Added new H5Lget_name_by_idx() routine to query the name of a link
+ according to the order within an index.
+ - QAK - 2006/11/12
+ - Added new H5Rget_name() routine to determine the name of the object
+ that a reference points to, as long as the object is still
+ reachable in the group hierarchy.
+ - QAK - 2006/11/10
+ - Added new H5Lget_info_by_idx() routine to query the link information
+ according to the order within an index.
+ - QAK - 2006/11/10
+ - Added feature to H5Iget_name to allow retrieving the name of any
+ object's ID, as long as the object is still reachable in the
+ group hierarchy.
+ - LA - 2006/11/01
+ - Added External and User-defined links.
+ External links are links from one HDF5 file to another; they
+ require both the name of the file and a path within that file.
+ User-defined links allow users to supply callback functions
+ for link traversals, allowing links to exhibit essentially
+ any behavior.
+ External links are a kind of user-defined link, so their default
+ behavior can be overridden by the user.
+ -JML 2006/8/23
+ - Added H5Oopen and H5Oclose for opening objects of unknown type
+ (as link callback functions do).
+ -JML 2006/8/23
+ - Added H5Oopen_by_addr, H5Oincr_refcount, and H5Odecr_refcount for
+ opening objects by address. Be very careful with these!
+ -JML 2006/8/23
+ - Added H5Fget_intent to get the "intent" of a file (whether it
+ was opened with read-write access or read-only.
+ -JML 2006/8/23
+ - Added Link Access Property Lists. They currently contain two
+ properties, nlinks (H5Pget/set_nlinks) and elink_prefix
+ (H5Pget/set_elink_prefix). nlinks controls how many soft and
+ user-defined traversals are allowed before HDF5 assumes it has
+ found a cycle (previously this defaulted to 16).
+ The elink_prefix is a filesystem path that is prefixed to the
+ names of any external link files opened using this LAPL.
+ -JML 2006/8/23
+ - Add H5L link APIs. Old APIs (H5Glink, H5Gmove, etc.) are still
+ supported but deprecated.
+ New APIs are:
+ H5Llink - create a link to an object given its ID
+ H5Lmove - just like H5Gmove2
+ H5Lcopy - copy a link without copying the underlying object
+ H5Lcreate_hard - like H5Glink2 for hard links
+ H5Lcreate_soft - like H5Glink2 for soft links
+ H5Ldelete - just like H5Gunlink
+ H5Lget_val - just like H5Gget_linkval
+ H5Lget_info - gets link-specific info (like H5Gget_objinfo)
+
+ In addition, H5Gcreate_anon, H5Tcommit_anon, and H5Dcreate_anon
+ no longer create links to objects; objects must be manually linked
+ using H5Llink or they will be deleted when the ID is closed.
+
+ Link Creation Property Lists can be used to pass character
+ encoding (ASCII or UTF-8) for link names and to set the Intermediate
+ Group Creation Flag:
+ H5Pset_char_encoding, H5Pget_char_encoding
+ H5Pset_copy_object, H5Pget_copy_object
+ -JML 2006/7/5
+ - Added managements of collective IO supports for chunking storage
+ inside parallel HDF5
+ 1) Implemented One IO with collective mode for all chunks in the
+ application by building one MPI derived datatype accross all
+ chunks.
+ 2) Implemented the decision-making support to do collective IO inside
+ MPI-IO per chunk.
+ 3) Added the decision-making support to do one IO accross all chunks
+ or to do multiple IOs with each IO per chunk.
+ 4) Added the support to handle the case some processes won't do any IOs in
+ collectively.
+ 5) Some MPI-IO package(mpich 1.2.6 or lower, e.g.) cannot handle
+ collective IO correctly for the case when some processes have no
+ contributions to IOs, a special macro is added to change
+ collective IO mode to independent IO mode inside HDF5 library.
+
+ Currently we find that MPICH at Linux and vender MPI-IO package at NCSA
+ Altix cannot handle this case.
+
+ "hdf5_mpi_special_collective_io_works=${hdf5_mpi_special_collective_io_works='no'}"
+ has been added at the end of file <ia64-linux-gnui> and
+ <linux-gnulibc1>.
+
+ If MPI-IO packages at your Linux and Altix support this case,
+ please comment out the last line and report to us at
+ help@hdfgroup.org. We can tune in our configuration to
+ support this.
+
+ KY - 2006/02/16
+ - Added character encoding to attribute creation property lists.
+ JML - 2006/01/02
+ - Added H5Gcopy() routine to copy objects between while keeping
+ data in compressed form. QAK - 2005/11/06
+ - Added H5Sextent_equal() routine. QAK - 2005/11/06
+ - Added HSYS_ERROR which retrieves the system error message and pushes
+ it to the error stack. This gives more information of the failed
+ system call. AKC - 2005/08/04
+ - Added H5F_OBJ_LOCAL flag to H5Fget_obj_count() & H5Fget_obj_ids(), to
+ allow querying for objects in file that were opened with a particular
+ file ID, instead of all objects opened in file with any file ID.
+ QAK - 2005/06/01
+ - Added H5T_CSET_UTF8 character set to mark datatypes that use the
+ UTF-8 Unicode character encoding. Added tests to ensure that
+ library handles UTF-8 object names, attributes, etc. -JL 2005/05/13
+ - HDF5 supports collective MPI-IO for irregular selection with HDF5
+ dataset. Irregular selection is when users use H5Sselect_hyperslab
+ more than once for the same dataset.
+ Currently, not all MPI-IO packages support complicated MPI derived
+ datatype used in the implementation of irregular
+ selection INSIDE HDF5.
+ 1) DEC 5.x is not supporting complicated derived datatype.
+ 2) For AIX 5.1,
+ if your poe version number is 3.2.0.19 or lower,
+ please edit powerpc-ibm-aix5.x under hdf5/config,
+ Find the line with
+ << hdf5_mpi_complex_derived_datatype_works>>
+ and UNCOMMENT this line before the configure.
+ check poe version with the following command:
+ lpp -l all | grep ppe.poe
+ 3) For Linux cluster,
+ if mpich version is 1.2.5 or lower, collective irregular selection
+ IO is not supported, internally independent IO is used.
+ 4) For IRIX 6.5,
+ if C compiler version is 7.3 or lower, collective irregular selection
+ IO is not supported, internally independent IO is used.
+ 5) For platforms which internally used mpich, if the
+ mpich version is 1.2.5 or lower, please find the
+ corresponding config file and add
+ hdf5_mpi_complex_derived_datatype_works='no' at the
+ end of the configuration file. For example, at NCSA
+ SGI Altix, the internal mpich library is 1.2.5. So
+ hdf5_mpi_complex_derived_datatype_works='no' should be
+ added at the end of the config file ia64-linux-gnu.
+ KY - 2005/09/12
+ We also found not all MPI-IO packages support collective IO with one
+ or more processes to have no contributions to IO.
+ For mpich version 1.2.6 or lower and all IRIX machine,
+ if the library checks that there are no IO contributions for some
+ processes, collective IO request is replaced with
+ independent inside HDF5.
+ KY - 2006/05/04
+
+ - HDF5 N-bit filter
+ HDF5 support N-bit filter from this version,
+ The N-Bit filter is used effectively for compressing data of N-Bit
+ datatype as well as compound and array datatype with N-Bit fields.
+ KY - 2005/04/15
+ - HDF5 scaleoffset filter
+ HDF5 supports scaleoffset filter for users to do data
+ compression through HDF5 library.
+ Scale-Offset compression performs a scale and/or offset operation
+ on each data value and truncates the resulting value to a minimum
+ number of bits and then stores the data.
+ Scaleoffset filter supports floating-point and integer datatype.
+ Please check the HDF5 reference manual for this.
+ KY - 2005/06/06
+ - Retired SRB vfd (--with-srb). Functions H5Pset_fapl_srb and
+ H5Pget_fapl_srb were removed. EIP - 2005/04/07
+ - Retired GASS vfd (--with-gass). Functions H5Pset_fapl_gass and
+ H5Pget_fapl_gass are removed too. AKC - 2005/3/3
+ - Pablo was removed from the source code EIP - 2005/01/21
+ - Modified registration of SZIP to dynamically detect the presence
+ or absence of the encoder. Changed configure and Makefiles,
+ and tests to dynamically detect encoder. BEM - 2004/11/02
+ - Added function H5Pget_data_transform, together with the previously
+ added H5Pset_data_transform, to support the data transform
+ feature. AKC - 2004/10/26
+ - Compound datatype has been enhanced with a new feature of size
+ adjustment. The size can be increased and decreased(without
+ cutting the last member) as long as it doesn't go down to zero.
+ No API change is involved. SLU - 2004/10/1
+ - Put back 6 old error API functions to be backward compatible with
+ version 1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear,
+ H5Eset_auto, H5Eget_auto. Their new equivalent functions are
+ called H5Epush_stack, H5Eprint_stack, H5Ewalk_stack,
+ H5Eclear_stack, H5Eset_auto_stack, H5Eget_auto_stack. SLU -
+ 2004/9/2
+ - 4 new API functions, H5Tencode, H5Tdecode, H5Sencode, H5Sdecode were
+ added to the library. Given object ID, these functions encode and
+ decode HDF5 objects(data type and space) information into and from
+ binary buffer. SLU - 2004/07/21
+ - Modified the way how HDF5 calculates 'pixels_per_scanline' parameter for
+ SZIP compression. Now there is no restriction on the size and shape of the
+ chunk except that the total number of elements in the chunk cannot be
+ bigger than 'pixels_per_block' parameter provided by the user.
+ EIP - 2004/07/21
+ - Added support for SZIP without encoder. Added H5Zget_filter_info
+ and changed H5Pget_filter and H5Pget_filter_by_id to support this
+ change. JL/NF - 2004/06/30
+ - SZIP always uses K13 compression. This flag no longer needs to
+ be set when calling H5Pset_szip. If the flag for CHIP
+ compression is set, it will be ignored (since the two are mutually
+ exclusive). JL/NF - 2004/6/30
+ - A new API function H5Fget_name was added. It returns the name
+ of the file by object(file, group, data set, named data type,
+ attribute) ID. SLU - 2004/06/29
+ - Added support for user defined identifier types. NF/JL - 2004/06/29
+ - A new API function H5Fget_filesize was added. It returns the
+ actual file size of the opened file. SLU - 2004/06/24
+ - New Feature of Data transformation is added. AKC - 2004/05/03.
+ - New exception handler for datatype conversion is put in to
+ replace the old overflow callback function. This exception
+ handler is set through H5Pset_type_conv_cb function.
+ SLU - 2004/4/27
+ - Added option that if $HDF5_DISABLE_VERSION_CHECK is set to 2,
+ will suppress all library version mismatch warning messages.
+ AKC - 2004/4/14
+ - A new type of dataspace, null dataspace(dataspace without any
+ element) was added. SLU - 2004/3/24
+ - Data type conversion(software) from integer to float was added.
+ SLU - 2004/3/13
+ - Data type conversion(software) from float to integer was added.
+ Conversion from integer to float will be added later.
+ SLU -2004/2/4
+ - Added new H5Premove_filter routine to remove I/O pipeline filters
+ from dataset creation property lists. PVN - 2004/01/26
+ - Added new 'compare' callback parameter to H5Pregister & H5Pinsert
+ routines. QAK - 2004/01/07
+ - Data type conversion(hardware) between integers and floats was added.
+ SLU 2003/11/21
+ - New function H5Iget_file_id() was added. It returns file ID given
+ an object(dataset, group, or attribute) ID. SLU 2003/10/29
+ - Added new fields to the H5G_stat_t for more information about an
+ object's object header. QAK 2003/10/06
+ - Added new H5Fget_freespace() routine to query the free space in a
+ given file. QAK 2003/10/06
+ - Added backward compatability with v1.6 for new Error API. SLU -
+ 2003/09/24
+ - Changed 'objno' field in H5G_stat_t structure from 'unsigned long[2]'
+ to 'haddr_t'. QAK - 2003/08/08
+ - Changed 'fileno' field in H5G_stat_t structure from 'unsigned long[2]'
+ to 'unsigned long'. QAK - 2003/08/08
+ - Changed 'hobj_ref_t' type from structure with array field to 'haddr_t'.
+ QAK - 2003/08/08
+ - Object references (hobj_ref_t) can now be compared with the 'objno'
+ field in the H5G_stat_t struct for testing if two objects are the
+ same within a file. QAK - 2003/08/08
+ - Switched over to new error API. SLU - 2003/07/25
+
+ Parallel Library:
+ -----------------
+ - Added mpich2 as a testing "platform" informally. AKC - 2005/9/28.
+ - A dataset created in serial mode with H5D_ALLOC_TIME_INCR allocation
+ setting was not extendible, either explicitly by H5Dextend or
+ implicitly by writing to unallocated chunks. Library now allocates
+ more space when needed or directed if the file is opened by parallel
+ mode, independent of what the dataset allocation mode is.
+ CC/AKC - 2005/08/29.
+ - Allow compressed, chunked datasets to be read in parallel.
+ QAK - 2004/10/04
+ - Add options of using atomicity and file-sync to test_mpio_1wMr.
+ AKC - 2003/11/13
+ - Added parallel test, test_mpio_1wMr, which tests if the
+ underlaying parallel I/O system is conforming to the POSIX
+ write/read requirement. AKC - 2003/11/12

+
+Bug Fixes since HDF5-1.6.0 release
+==================================
+
+ Library
+ -------
+ - Changed library's behavior for reading files that might have
+ corrupted object header information from a previous (buggy)
+ version of the library. By default, the library now rebuilds the
+ correct object header information instead of issuing an error.
+ Previous "strict" file format interpretation can be enabled with
+ the "--enable-strict-format-checks" configure option.
+ QAK - 2008/01/13
+ - Fixed several bugs with writing fill values for datasets that have
+ a variable-length datatype or component datatype. QAK - 2007/06/19
+ - STDIO driver didn't support files bigger than 2GB because the OFFSET
+ parameter of fseek is of type LONG INT, not big enough for big files.
+ Use fseeko instead for big files if it's available on the system.
+ SLU - 2007/4/5
+ - Fixed a bug in H5Sselect_valid() that caused an incorrect value to
+ be returned (0) instead of FAIL on error conditions such as the
+ selection or extent not being defined. CMC - 2007/01/17
+ - Fixed the MULTI driver problem (Bug #731) that corruptted the data.
+ SLU - 2007/1/12
+ - Fixed file corruption bug which could write an incorrect number of
+ messages to an object's header under certain circumstances.
+ Generally, the sequence of actions to generate this bug looks
+ like this:
+ - Create an object
+ - Close the file
+ - Re-open the file
+ - Add 2 (or more) attributes to the object
+ - Close the file
+ - Re-open the file
+ - Delete one of the attributes on the object
+ - Add a smaller attribute to the object
+ - Delete the smaller atttribute on the object
+ - Add a larger attribute on the object
+
+ After this, the number of header messages stored for the object
+ will be off by one. Other sequences of modifying attributes on an
+ object could also trigger this bug. If you are opening an
+ object and the bottom few messages of the HDF5 error stack
+ resembles this, the object has been affected by this bug:
+
+ #007: ../../hdf5_v1.6/src/H5C.c line 3887 in H5C_load_entry(): unable to load entry
+ major(08): Meta data cache layer
+ minor(40): Unable to load metadata into cache
+ #008: ../../hdf5_v1.6/src/H5Ocache.c line 332 in H5O_load(): corrupt object header - too few messages
+ major(12): Object header layer
+ minor(40): Unable to load metadata into cache
+
+ Specifically, "corrupt object header" is the best string to search
+ for in the HDF5 error stack output.
+
+ If your files have been affected by this bug, or you are concerned
+ that your files might have been, please contact the HDF Helpdesk
+ at help@hdfgroup.org for a tool to detect and repair files
+ affected by this problem. QAK - 2006/6/16
+ - Fixed various problems with retrieving names of objects, especially
+ with mounted files. QAK - 2005/12/25
+ - Fixed core dump when closing root groups opened through two different
+ file handles that operate on the same actual file. QAK - 2005/10/02
+ - Corrected errors when performing various operations on a group opened
+ by dereferencing an object reference. QAK - 2005/07/30
+ - Fixed a bug with named datatypes where a copy of a named datatype
+ used to create a dataset would accidentally use the original
+ named datatype for the dataset's datatype. QAK - 2005/07/23
+ - Made H5Fget_name() be consistent and always return name of actual
+ file the ID is in. (Instead of the name of the top file in a
+ file mounting hierarchy). QAK - 2005/07/19
+ - Reworked internal file mounting semantics to hopefully eliminate
+ mounting problems. We now require that files that are mounting
+ together all have the same "file close degree". QAK - 2005/07/19
+ - More bug fixes on holding open files that are mounted and have
+ IDs open. QAK - 2005/07/14
+ - Don't unmount child files until the parent file actually closes.
+ (Previously, if an object is holding open a file, the child files
+ would get unmounted too early). QAK - 2005/07/05
+ - Fixed bug where unmounted files could cause the library to go into
+ an infinite loop when shutting down. QAK - 2005/06/30
+ - The library didn't save the information of family driver in file.
+ The original file member size was lost after file was closed (see
+ bug #213). This has been fixed by saving driver name and member
+ file size in the superblock. SLU - 2005/6/24
+ - Fixed bug with hyperslab selections that use selection offsets and
+ operate on chunked datasets going into infinite loop or dumping
+ core. QAK - 2005/06/17
+ - Corrected memory leak and possible corruption when opening a group.
+ QAK - 2005/06/17
+ - Added check for opaque datatype tags being too long (check against
+ H5T_OPAQUE_TAG_MAX, currently set to 256). QAK - 2005/06/14
+ - Fixed various errors in maintaining names for open objects in the
+ face of unusual mount & unmount operations. QAK - 2005/06/08
+ - "SEMI" and "STRONG" file close degree settings now apply only to the
+ particular file ID being closed, instead of operating on all open
+ file IDs for a given file. QAK - 2005/06/01
+ - For family driver, the library didn't save member size in file.
+ When file is reopened, the size of 1st member file determine the
+ member size. Now member size is saved in file and is used to
+ define member file size. Wrong file access property of member size
+ will result in a failure. Using any other driver except family
+ will cause library to return error. So is multi driver. SLU -
+ 2005/05/24
+ - Fixed error in opening object in group that was opened in mounted
+ file which has been unmounted. QAK - 2005/03/17
+ - Fixed a racing condition in MPIPOSIX virtual file drive close
+ function. Now all processes must completed the close before any
+ of them is returned. This prevents some "faster" processes start
+ accessing the file for another purpose (e.g., open with truncate)
+ while other "slower" processes have not closed the same file with
+ the previous purpose. AKC - 2005/03/01
+ - H5Tget_member_value calls for enum datatype didn't return correct
+ value if H5Tenum_valueof was called first. It's fixed. SLU -
+ 2005/02/08
+ - For variable-length string, H5Tget_class returned H5T_STRING as its
+ class. But H5Tdetect_class and H5Tget_member_class considered it
+ as H5T_VLEN. This is fixed to let all these 3 functions treat it
+ as H5T_STRING. SLU - 2005/02/08
+ - The byte order of 1-byte integer types was fixed as little endian
+ even on a big-endian machine. This has been corrected. SLU -
+ 2005/02/07
+ - Fix segmentation fault when calling H5Fflush with an attribute that
+ hasn't had a value written to it open. QAK - 2004/10/18
+ - Back up supporting bitfield and time types in H5Tget_native_type.
+ Leave it to future support. The function simply returns error
+ message of "not support" for bitfield and time types.
+ SLU - 2004/10/5
+ - Fixed address check in Core VFL driver to avoid spurious address/size
+ overflows for odd valued addresses and/or sizes. QAK - 2004/09/27
+ - Fixed parallel bug in which some processes attempted collective
+ I/O while others did independent I/O. Bug appeared when some
+ processes used point selections, and others didn't. JRM - 2004/9/15
+ - Corrected error where dataset region references were written in an
+ incorrect way on Cray machines. PVN & QAK - 2004/09/13
+ - The H5Tget_native_type now determines the native type for integers
+ based on the precision. This is to avoid cases of wrongly converting
+ an int to a short in machines that have a short of 8 bytes but with
+ 32bit precision (e.g Cray SV1). PVN - 2004/09/07
+ - Changed H5Dread() to not overwrite data in an application's buffer
+ with garbage when accessing a chunked dataset with an undefined
+ fill value and an unwritten chunk is uncountered. QAK - 2004/08/25
+ - Fixed error which could cause a core dump when a type conversion
+ routine was registered after a compound datatype had been
+ converted and then an equivalment compound datatype was converted
+ again. QAK - 2004/08/07
+ - Fixed memory overwrite when encoding "multi" file driver information
+ for file's superblock. QAK - 2004/08/05
+ - Fixed obscure bug where a filter which failed during chunk allocation
+ could allow library to write uncompressed data to disk but think
+ the data was compressed. QAK - 2004/07/29
+ - Fixed bug where I/O to an extendible chunked dataset with zero-sized
+ dimensions would cause library to fail an assertion.
+ QAK - 2004/07/27
+ - Fixed bug where chunked datasets which have filters defined,
+ allocation time set to "late" and whose chunks don't align with
+ the dataspace bounds could have incorrect data stored when
+ overwriting the entire dataset on the first write. QAK - 2004/07/27
+ - Added check to ensure that dataspaces have extents set. JML-2004/07/26
+ - Fixed bug on some Solaris systems where HDF5 would try to use
+ gettimeofday() when that function didn't work properly.
+ JML - 2004/07/23
+ - Fixed bug in H5Sset_extent_simple where setting maximum size to
+ non-zero, then to zero would cause an error. JML - 2004/07/20
+ - Allow NULL pointer for buffer parameter to H5Dread & H5Dwrite
+ when not writing data ("none" selection or hyperslab or point
+ selection with no elements defined). QAK - 2004/07/20
+ - Calling H5Gcreate() on "/" or "." throws an error instead of
+ failing quietly. JML - 2004/07/19
+ - Fixed bug where setting file address size to be very small could
+ trigger an assert if the file grew to more than 64 KB. Now throws
+ an error and data can be recovered. JL/NF - 2004/07/14
+ - Fixed bug where "resurrecting" a dataset was failing.
+ QAK - 2004/07/14
+ - Fixed bug where incorrect data could be read from a chunked dataset
+ after it was extended. QAK - 2004/07/12
+ - Fixed failure to read data back from file of compound type with
+ variable-length string as field. SLU - 2004/06/10
+ - Fixed potential file corruption bug when a block of metadata could
+ overlap the end of the internal metadata accumulator buffer and
+ the buffer would be extended correctly, but would incorrectly
+ change it's starting address. QAK - 2004/06/09
+ - Opaque datatype with no tag failed for some operations. Fixed.
+ SLU - 2004/6/3
+ - Fixed potential file corruption bug where dimensions that were
+ too large (a value greater than could be represented in 32-bits)
+ could cause the incorrect amount of space to be allocated in a
+ file for the raw data for the dataset. QAK - 2004/06/01
+ - Fixed dtypes "sw long double -> double" failure in QSC class
+ machines. AKC - 2004/4/16
+ - Fixed problem with fletcher32 filter when converting data of different
+ endianess. PVN - 2004/03/10
+ - Fixed problem with H5Tget_native_type() not handling opaque fields
+ correctly. QAK - 2004/01/31
+ - Fixed several errors in B-tree deletion code which could cause a
+ B-tree (used with groups and chunked datasets) to become corrupt
+ with the right sequence of deleted objects. QAK - 2004/01/19
+ - Fixed small internal memory leaks of fill-value information.
+ QAK - 2004/01/13
+ - Fixed bug that caused variable-length datatypes (strings or sequences)
+ used for datasets in files with objects that were unlinked to
+ fail to be read/written to a file. QAK - 2004/01/13
+ - Detect situation where szip 'pixels per block' is larger than the
+ fastest changing dimension of a dataset's chunk size and disallow
+ this (due to limits in szip library). QAK - 2003/12/31
+ - Fixed bug with flattened hyperslab selections that would generate
+ incorrect hyperslab information with certain high-dimensionality
+ combinations of start/stride/count/block information.
+ QAK - 2003/12/31
+ - Fixed bug with variable-length datatypes used in compound datatypes.
+ SLU - 2003/12/29
+ - Fixed bug in parallel I/O routines that would cause reads from
+ "short datasets" (datasets which were only partially written out)
+ to return invalid data. QAK & AKC - 2003/12/19
+ - Fixed bug where scalar dataspaces for attributes were reporting as
+ simple dataspaces. QAK - 2003/12/13
+ - Fixed problem with selection offsets of hyperslab selections in
+ chunked datasets causing the library to go into an infinite loop.
+ QAK - 2003/12/13
+ - Fixed H5Giterate to avoid re-using index parameter after iteration
+ callback has been called (allows iteration callback to modify the
+ index parameter itself). QAK - 2003/12/06
+ - Fixed various floating-point conversion problems, including a
+ change which could corrupt data when converting from double->float.
+ QAK - 2003/11/24
+ - Changed "single process" metadata writing in library to collective
+ I/O by all processes, in order to guarantee correct data being
+ written with MPI-I/O. QAK - 2003/11/20
+ - Fixed problems with fill values and variable-length types and also
+ I/O on VL values that were set to NULL. QAK - 2003/11/08
+ - Fixed problems with MPI datatypes that caused ASCI Q machine to
+ hang. QAK - 2003/10/28
+ - Removed HDF5_MPI_PREFER_DERIVED_TYPES environment variable support,
+ since it had no benefit. QAK - 2003/10/28
+ - Single hyperslab selections (which were set with only one call to
+ H5Sselect_hyperslab) that had dimensions that could be "flattened"
+ but were interspersed with dimensions that could not be flattened
+ were not correctly handled, causing core dumps. QAK - 2003/10/25
+ - Fixed incorrect datatype of the third parameter to the Fortran90
+ h5pset(get)_cache_f subroutine (INTEGER to INTEGER(SIZE_T))
+ EIP - 2003/10/13
+ - Fixed problems with accessing variable-length data datatypes on
+ Crays. QAK - 2003/10/10
+ - Fixed potential file corruption bug when too many object header
+ messages (probably attributes, from a user perspective) were
+ inserted into an object header and certain other conditions were
+ met. QAK - 2003/10/08
+ - Changed implementation of internal ID searching algorithm to avoid
+ O(n) behavior for many common cases. QAK - 2003/10/06
+ - Allow partial parallel writing to compact datasets. QAK - 2003/10/06
+ - Correctly create reference to shared datatype in attribute, instead
+ of making a copy of the shared datatype in the attribute.
+ QAK - 2003/10/01

+ QAK - 2003/08/25
+ - Corrected bug in H5Tget_native_type which would drop string datatype
+ metadata (padding, etc.) QAK - 2003/08/25
+ - Corrected bugs in H5Gget_num_objs, H5Gget_objname_by_idx and
+ H5Gget_objtype_by_idx to allow them to accept location IDs, not just
+ group IDs. QAK - 2003/08/21
+ - Corrected bug when using scalar dataspace for memory selection and
+ operating on chunked dataset. QAK - 2003/08/18
+ - Corrected bugs with multiple '/' characters in names for H5Glink
+ and H5Gunlink. QAK - 2003/08/16
+ - Corrected bug with user blocks that didn't allow a user block to
+ be inserted in front of a file after the file was created.
+ QAK - 2003/08/13
+ - Corrected errors with using point selections to access data in
+ chunked datasets. QAK - 2003/07/23
+ - Corrected error with variable-length datatypes and chunked datasets
+ caused H5Dwrite to fail sometimes. QAK - 2003/07/19
+ - Modified library and file format to support storing indexed storage
+ (chunked dataset) B-tree's with non-default internal 'K' values.

+
+ Configuration
+ -------------
+ - Configure can now use any tr command. No more need for
+ defining variable TR nor is it supported. -AKC 2006/05/19
+ - Parallel I/O with the MPI-I/O driver will no longer work if the
+ filesystem is not POSIX compliant. The "HDF5_MPI_1_METAWRITE"
+ environment variable has been removed. QAK - 2004/01/30
+ - Fixed the error that cause "make install" to fail because of the
+ macro definition syntax of "prefix?=..." AKC - 2003/07/22
+
+ Performance
+ -------------
+ - Optimized I/O for enumerated datatypes that are a superset of source
+ enumerated datatype. QAK - 2005/03/19
+ - More optimizations to inner loops of datatype conversions for
+ integers and floats which give a 10-50% speedup. QAK - 2003/11/07

+
+Known Problems
+==============
+* We discovered two problems when running collective IO parallel HDF5 tests
+ with chunking storage on 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 wrong derived data type and corrupt data
+ may be generated.
+ This only happens when turning on collective IO with chunking storage
+ with some complex selections. We haven't found these problems on other
+ MPI-IO compilers. If you encounter these problems, you may use Independent IO
+ instead.
+
+ 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. Higher level of optimization
+ causes failures in several HDF5 library tests.
+* For HPUX 11.23 many tools tests failed for 64-bit version when linked to the
+ shared libraries (tested for 1.8.0-beta2)
+* For SNL, Red Storm: only paralle HDF5 is supported. The serial tests pass
+ and the parallel tests also pass with lots of non-fatal error messages.
+* For LLNL, uP: both serial and parallel pass. Zeus: serial passes but
+ parallel fails with a known proglem in MPI. ubgl: serial passes but
+ parallel fails.
+* on SUN 5.10 C++ test 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, Scaleoffset filter isn't supported. The filter cannot be applied to
+ HDF5 data generated on VAX. Scaleoffset filter only supports 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, we found that if more than two processes
+ contribute no IO and the application asks to do IO with collective, we found
+ that when using 4 processors, a simple collective write will be hung
+ sometimes. This can be verified with t_mpi test under testpar.
+* On IRIX6.5, when C compiler version >7.4, the complicate MPI derived data type
+ code will work. However, the user should be aware to enlarge MPI_TYPE_MAX environment
+ variable to some certian value in order to use collective irregular selection code.
+ For example, the current parallel HDF5 test needs to enlarge MPI_TYPE_MAX to
+ 200,000 to make the test pass.
+* The dataset created or rewritten with the v1.6.3 library or after can't
+ be read with the v1.6.2 library or before when 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 wasn't 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 is no
+ longer the same as before on little-endian system. The library release
+ after 1.6.4 can still read the dataset created or rewritten with the library
+ of v1.6.2 or before. SLU - 2005/6/30
+* For the version 6(6.02 and 6.04) of Portland Group compiler on AMD Opteron
+ processor, there's a bug in the compiler for optimization(-O2). The library
+ failed in several tests but all related to 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". HDF5 does not use sockets (except for stream-VFD). This is
+ due to problems of the poe command trying to set up the debug socket.
+ Check if there are many old /tmp/s.pedb.* staying around. These are
+ sockets used by the poe command and left behind due to failed commands.
+ Ask your system administrator to clean them out. Lastly, request IBM
+ to provide a mean to run poe without the debug socket.
+
+* The C++ library's tests fails when compiling with PGI C++ compiler. The
+ workaround until the problem is correctly handled is to use the
+ flag "--instantiate=local" prior to the configure and build steps, as:
+ setenv CXX "pgCC --instantiate=local" for pgCC 5.02 and higher
+
+
+* The stream-vfd test uses ip port 10007 for testing. If another
+ application is already using that port address, the test will hang
+ indefinitely and has to be terminated by the kill command. To try the
+ test again, change the port address in test/stream_test.c to one not
+ being used in the host.
+
+* 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 don't use this option on these platforms
+ during configuration.
+
+* With the gcc 2.95.2 compiler, HDF 5 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 Stream VFD was not tested yet under Windows. It is not supported
+ in the TFLOPS machine.
+
+
+* The ./dsets tests failed in 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.
+
+* Certain platforms give false negatives when testing h5ls:
+ - Cray J90 and Cray T90IEEE give errors during testing when displaying
+ some floating-point values. These are benign differences due to
+ the different precision in the values displayed and h5ls appears to
+ be dumping floating-point numbers correctly.
+
+* Before building HDF5 F90 Library from source on Crays
+ replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src
+ subdirectory in the top level directory with the Cray-specific files
+ from this site:
+ ftp://www.hdfgroup.uiuc.edu/pub/outgoing/hdf5/hdf5-1.8.0-pre/PATCH/
+
+* 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 HDF5 fortran library,
+ compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90
+ complaining about exit subroutine. Comment out the line
+ IF (total_error .ne. 0) CALL exit (total_error)
+
+* On IA32 and IA64 systems, if you use a compiler other than GCC (such as
+ Intel's ecc or icc compilers), you will need to modify the generated
+ "libtool" program after configuration is finished. On or around line 104 of
+ the libtool file, there are lines which look like:
+
+ # How to pass a linker flag through the compiler.
+ wl=""
+
+ change these lines to this:
+
+ # How to pass a linker flag through the compiler.
+ wl="-Wl,"
+
+ UPDATE: This is now done automatically by the configure script. However, if
+ you still experience a problem, you may want to check this line in the
+ libtool file and make sure that it has the correct value.
+
+* Information about building with PGI and Intel compilers is available in
+ INSTALL file sections 5.7 and 5.8
+
+* 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 HDF 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 h5copy tool

+
+New Features
+============
+ Configuration:
+ -------------------------
+ '--enable-stream-vfd' and '--disable-stream-vfd' are no longer valid
+ configure options because the stream I/O driver has ben removed from
+ the distribution.
+
+ Source code distribution
+ ========================
+ Library:
+ --------
+ The stream I/O driver is not included with the HDF5 Library in this
+ release. The source code files hdf5/src/H5FDstream.c and
+ hdf5/src/H5FDstream.h and the driver ENUM value H5FD_STREAM have been
+ removed.
+
+ Parallel Library:
+ -----------------
+ None
+
+ Tools:

+
+Support for New Platforms, Languages and Compilers
+==================================================
+
+No new platorms, languages, or compilers are supported in this release.
+
+
+Bug Fixes since HDF5-1.6.6 Release
+==================================
+
+ Library
+ -------
+ - H5Iget_name could not be used with an object identifier returned
+ by H5Rdereference; the function would not be able to determine
+ a valid object name. It has been fixed. SLU - 2008/1/30
+ - Changed library's behavior for reading files that might have
+ corrupted object header information from a previous (buggy)
+ version of the library. By default, the library now rebuilds the
+ correct object header information instead of issuing an error.
+ Previous "strict" file format interpretation can be enabled with
+ the "--enable-strict-format-checks" configure option.
+ QAK - 2008/01/13
+ - Fixed bug in H5Epush() which was clearing the error stack before
+ pushing new error value. QAK - 2007/08/23
+ - Fixed bug in H5Ewalk() which was not passing back the return value
+ from error stack walking callback. QAK - 2007/08/23

+
+ A listing of interface changes from release to release can be found
+ in the document "HDF5 Software Changes from Release to Release":
+
+ http://hdfgroup.org/HDF5/doc1.6/ADGuide/Changes.html
+
+ Since the stream I/O driver is not included in this release, the
+ functions H5Pset_fapl_stream and H5Pget_fapl_stream and the stream
+ ENUM value H5FD_STREAM have been removed from the documentation.

+
+Known Problems
+==============
+* We discovered two problems when running collective IO parallel HDF5 tests
+ with chunking storage with 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.
+ This only happens when turning on collective IO with chunking storage
+ with some complex selections. We haven't found these problems on other
+ MPI-IO compilers. If you encounter these problems, you may use Independent
+ IO instead.
+
+ To avoid this problem, 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
+
+* QSC (an HP alpha-based OSF1 cluster) does not create h5pfc correctly. It
+ does not include the -lmpi properly. This will be fixed in the next
+ release. AKC - 2007/08/07.
+
+* On IRIX64 6.5 (UCAR SGI mop1), when testing HDF5 tools with an HDF5 shared
+ library, especially for h5repacktst and h52gifgentst, the following (or a
+ similar) error message may appear:
+ "523648:lt-h5repacktst: rld: Fatal Error: Cannot Successfully map soname
+ 'libh5test.so.1' under any of the filenames .......(bunch of directories)
+ "
+ And the testing will fail.
+
+ We believe this is a libtool problem. One way to get rid of this is to
+ add the paths of libh5test.so.1 and libh5.so.1 to the shared library path.
+
+ For 32-bit:
+ You may do this, under csh:
+ setenv LD_LIBRARYN32_PATH .......(existing paths):[full path of HDF5
+ directory/test/.libs]:[full path of HDF5 directory/src/.libs]
+
+ For 64-bit:
+ setenv LD_LIBRARY64_PATH ......(existing paths):[full path of HDF5
+ directory/test/.libs]:[full path of HDF5 directory/src/.libs]
+
+ NOTE: This problem ONLY affects the testing of the HDF5 library when you
+ build from source. It won't affect any applications that would like to link
+ with the HDF5 shared library since the shared library path needs to be set
+ anyway. KY - 2007/8/2
+
+* QSC (an HP alpha-based OSF1 cluster) failed the testpar/testphdf5 sub-test
+ "calloc". All other tests passed. This indicates that a dataset using
+ chunked storage created by serial HDF5 may not work properly with parallel
+ HDF5. The calloc test can be skipped by running "prun ... testphdf5 -x
+ calloc". AKC - 2007/7/12.
+
+* The Intel C Compiler for the Linux x86_64 platform (EM64T-based, v8.1) has
+ an optimization error in the datatypes conversion code. Before running
+ configure, edit the file config/intel-flags by changing the setting of
+ PROD_CFLAGS from -O3 to -O0. Then run configure. AKC - 2005/11/10.
+
+* When testing parallel HDF5 with the C compiler version MIPSpro 7.4.3 on IRIX
+ 6.5, set the environment variable MPI_TYPE_MAX to be a bigger number, for
+ example 120000, in order to pass the complicated collective IO tests inside
+ the parallel HDF5 library. This is not a problem inside the parallel HDF5
+ library. You can always set a bigger number on your system. KY - 2005/10/6
+
+* A contiguous or chunked dataset created by a sequential version of HDF5
+ might not be able to be modified with a parallel version of the library.
+ Use the H5Pset_alloc_time function with H5D_ALLOC_TIME_EARLY to set up the
+ dataset creation property list to avoid the problem. EIP - 2005/09/09
+
+* A dataset created or rewritten with the v1.6.3 library or after can't
+ be read with the v1.6.2 library or before when Fletcher32 EDC (a 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 wasn't 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 is no
+ longer the same as before on little-endian system. HDF5 library releases
+ after 1.6.4 can still read datasets created or rewritten with an HDF5
+ library of v1.6.2 or before. SLU - 2005/7/8
+
+* For version 6 (6.02 and 6.04) of the Portland Group compiler on AMD Opteron
+ processor, there's 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.
+
+* test/big fails sometimes with the message "Possible overlap with another
+ region." The test selects regions randomly, and this error occurs when
+ two regions overlap each other; it is a bug in the test and not in
+ HDF5. Since the error is triggered by a random situation, it will
+ usually disappear if the test is re-run.
+
+* Newer SGI MIPSpro compilers (version 7.4.x) support C99 features but
+ have a "guard" statement in stdint.h that will #error and skip the rest
+ of the header file if the C99 option is not used explicitly. Hardsetting
+ $CC to c99 will resolve the problem. AKC - 2004/12/13
+
+* 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 also fail with messages like "The socket name is already
+ in use". HDF5 does not use sockets. This is due to problems of the
+ poe command trying to set up the debug socket. Check 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. Ask your system
+ administrator to clean them out. Lastly, request IBM to provide a means
+ to run poe without the debug socket.
+
+* The h5dump tests may fail to match the expected output on some platforms
+ (e.g. parallel jobs, Windows) where the error messages directed to
+ "stderr" do not appear in the "right order" with output from stdout.
+ This is not an error.
+
+* 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 the IBM SP2 platform for the serial mode. The parallel mode works fine
+ with this option.
+
+ The --enable-static-exec configure flag also fails to correctly compile
+ on the HPUX 11.00.
+
+ It is suggested that you don't use this option on these platforms
+ during configuration.
+
+* Use the --disable-shared configure flag if building with an Absoft Fortran
+ compiler.
+
+* Information about building with PGI and Intel compilers is available in
+ INSTALL file sections 5.7 and 5.8.
+
+* In LANL QSC, the new cc compiler has problems converting small values of
+ long long (absolute values less than 1**-308) to double. This triggers
+ the test/dtypes to report failure in the following test:
+ Testing random sw long double -> double conversions
+ If -ieee is used, the converted doubles spread over the range 0.0 to
+ 10**-308. If -ieee is not used, the converted double values are mostly
+ 0.0, but occasionally appear as 10**-308. This has been reported to the
+ system staff.
+
+ All other tests have passed.
+
+* 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 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 scripts 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. JM - 2004/9/15

+
+
+Bug Fixes since HDF5-1.6.5 Release
+==================================
+
+ Library
+ -------
+ - Fixed several bugs with writing fill values for datasets that have
+ a variable-length datatype or component datatype. QAK -
+2007/06/19
+ - STDIO driver didn't support files bigger than 2GB because the OFFSET
+ parameter of fseek is of type LONG INT, not big enough for big
+ files. Use fseeko instead for big files if it's available on the
+ system. SLU - 2007/4/5
+ - Relaxed restrictions on attribute operations to allow a file ID to
+ be used as the "location ID". If a file ID is used, the attribute
+ operation will occur on the root group of the file.
+ QAK - 2007/02/09
+ - Fixed a bug in H5Sselect_valid() that caused an incorrect value to
+ be returned (0) instead of FAIL on error conditions such as the
+ selection or extent not being defined. CMC - 2007/01/05
+ - Fixed potential file corruption bug which could overwrite a portion
+ of an object's header when an attribute was renamed. If the new
+ name for the attribute was longer than the old name, it was
+possible
+ that the attribute would grow enough to overwrite another message
+ in the object's header. QAK - 2007/01/02
+ - Fixed file corruption bug which could write an incorrect number of
+ messages to an object's header under certain circumstances.
+ Generally, the sequence of actions to generate this bug looks
+ like this:
+ - Create an object.
+ - Close the file.
+ - Re-open the file.
+ - Add 2 (or more) attributes to the object.
+ - Close the file.
+ - Re-open the file.
+ - Delete one of the attributes on the object.
+ - Add a smaller attribute to the object.
+ - Delete the smaller atttribute on the object.
+ - Add a larger attribute on the object.
+
+ After this, the number of header messages stored for the object
+ will be off by one. Other sequences of modifying attributes on an
+ object could also trigger this bug. If you are opening an
+ object and the bottom few messages of the HDF5 error stack
+ resembles the following, the object has been affected by this bug:
+
+ #007: ../../hdf5_v1.6/src/H5C.c line 3887 in H5C_load_entry():
+unable to load entry
+ major(08): Meta data cache layer
+ minor(40): Unable to load metadata into cache
+ #008: ../../hdf5_v1.6/src/H5Ocache.c line 332 in H5O_load():
+corrupt object header - too few messages
+ major(12): Object header layer
+ minor(40): Unable to load metadata into cache
+
+ Specifically, "corrupt object header" is the best string to search
+ for in the HDF5 error stack output.
+
+ If your files have been affected by this bug, or you are concerned
+ that your files might have been, please contact the HDF Helpdesk
+ at help@hdfgroup.org for a tool to detect and repair files
+ affected by this problem. QAK - 2006/6/16

+
+Known Problems
+==============
+* QSC (an HP alpha-based OSF1 cluster) does not create h5pfc correctly. It
+ does not include the -lmpi properly. This will be fixed in the next
+ release. AKC - 2007/08/07.
+
+* On IRIX64 6.5 (UCAR SGI mop1), when testing HDF5 tools with an HDF5 shared
+ library, especially for h5repacktst and h52gifgentst, the following (or
+ similar) error message may appear:
+ "523648:lt-h5repacktst: rld: Fatal Error: Cannot Successfully map soname
+ 'libh5test.so.1' under any of the filenames .......(bunch of directories)
+ "
+ And the testing will fail.
+ We believe this is a libtool problem. One way to get rid of this is to
+ add the paths of libh5test.so.1 and libh5.so.1 to the shared library path.
+
+ For 32-bit:
+ You may do this, under csh:
+ setenv LD_LIBRARYN32_PATH .......(existing pathes):[full path of HDF5
+ directory/test/.libs]:[full path of HDF5 directory/src/.libs]
+
+ For 64-bit:
+ setenv LD_LIBRARY64_PATH ......(existing pathes):[full path of HDF5
+ directory/test/.libs]:[full path of HDF5 directory/src/.libs]
+
+ NOTE: This problem ONLY affects the testing of the HDF5 library when you
+ build from source. It won't affect any applications that would like to link
+ with the HDF5 shared library since the shared library path needs to be set
+ anyway. KY - 2007/8/2
+
+* QSC (an HP alpha-based OSF1 cluster) failed the testpar/testphdf5 sub-test
+ "calloc". All other tests passed. This indicates that a dataset using
+ chunked storage created by serial HDF5 may not work properly with parallel
+ HDF5. The calloc test can be skipped by running "prun ... testphdf5 -x
+ calloc". AKC - 2007/7/12.
+
+* The Intel C Compiler for the Linux x86_64 platform (EM64T-based, v8.1) has
+ an optimization error in the datax types conversion code. Before running
+ configure, edit the file config/intel-flags by changing the setting of
+ PROD_CFLAGS from -O3 to -O0. Then run configure. AKC - 2005/11/10.
+
+* When testing parallel HDF5 with the C compiler version MIPSpro 7.4.3 on IRIX
+ 6.5, set the environment variable MPI_TYPE_MAX to be a bigger number, for
+ example 120000, in order to pass the complicated collective IO tests inside
+ the parallel HDF5 library. This is not a problem inside the parallel HDF5
+ library. You can always set a bigger number on your system. KY - 2005/10/6
+
+* A contiguous or chunked dataset created by a sequential version of HDF5
+ might not be able to be modified with a parallel version of the library.
+ Use the H5Pset_alloc_time function with H5D_ALLOC_TIME_EARLY to set up the
+ dataset creation property list to avoid the problem. EIP - 2005/09/09
+
+* The dataset created or rewritten with the v1.6.3 library or after can't
+ be read with the v1.6.2 library or before when Fletcher32 EDC (a 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 wasn't 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 is no
+ longer the same as before on little-endian system. The library release
+ after 1.6.4 can still read the dataset created or rewritten with the library
+ of v1.6.2 or before. SLU - 2005/7/8
+
+* For version 6 (6.02 and 6.04) of the Portland Group compiler on AMD Opteron
+ processor, there's 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.
+
+* test/big fails sometimes with the message "Possible overlap with another
+ region." The test selects regions randomly, and this error occurs when
+ two regions overlap each other; it is a bug in the test and not in
+ HDF5. Since the error is triggered by a random situation, it will
+ usually disappear if the test is re-run.
+
+* Newer SGI MIPSpro compilers (version 7.4.x) support C99 features but
+ have a "guard" statement in stdint.h that will #error and skip the rest
+ of the header file if the C99 option is not used explicitly. Hardsetting
+ $CC to c99 will resolve the problem. AKC - 2004/12/13
+
+* 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 also fail with messages like "The socket name is already
+ in use". HDF5 does not use sockets (except for stream-VFD). This is
+ due to problems of the poe command trying to set up the debug socket.
+ Check 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.
+ Ask your system administrator to clean them out. Lastly, request IBM
+ to provide a means to run poe without the debug socket.
+
+* The h5dump tests may fail to match the expected output on some platforms
+ (e.g. parallel jobs, Windows) where the error messages directed to
+ "stderr" do not appear in the "right order" with output from stdout.
+ This is not an error.
+
+* The stream-vfd test uses ip port 10007 for testing. If another
+ application is already using that port address, the test will hang
+ indefinitely and has to be terminated by the kill command. To try the
+ test again, change the port address in test/stream_test.c to one not
+ being used in the host.
+
+* 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 the IBM SP2 platform for the serial mode. The parallel mode works fine
+ with this option.
+
+ The --enable-static-exec configure flag also fails to correctly compile
+ on the HPUX 11.00.
+
+ It is suggested that you don't use this option on these platforms
+ during configuration.
+
+* The Stream VFD is not supported under Windows.
+
+* Use the --disable-shared configure flag if building with Absoft Fortran
+ compiler.
+
+* Information about building with PGI and Intel compilers is available in
+ INSTALL file sections 5.7 and 5.8.
+
+* In LANL QSC, the new cc compiler has problems converting small values of
+ long long (absolute values less than 1**-308) to double. This triggers
+ the test/dtypes to report failure in the following test:
+ Testing random sw long double -> double conversions
+ If -ieee is used, the converted doubles spread over the range 0.0 to
+ 10**-308. If -ieee is not used, the converted double values are mostly
+ 0.0, but occasionally appear as 10**-308. This has been reported to the
+ system staff.
+
+ All other tests have passed.
+
+* 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 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 scripts 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. JM - 2004/9/15

============
Configuration:
- --------------
- - Removed stream-vfd from the HDF5 library. - AKC 2007/11/19.
- - Updated versions of autotools. HDF5 now uses automake 1.10.0,
- autoconf 2.61, and libtool 1.5.22. MAM - 2007/7/25.
- - Changed default fortran compiler to g95 when gcc is used. - AKC
- 2007/2/17.
- - 'make check-vfd' can now be run from the top level directory. Not all
- tests that 'make check' invokes work with certain Virtual File Drivers,
- so those tests have been skipped. - MAM 2006/7/17
- - Added the variable HDF5TestExpress to control how long tests run.
- Setting it to a value between 0 and 3 controls how thoroughly the
- library is tested, with 0 being an "exhaustive run" and 3 being a
- very quick "smoke test." 1 (a "full run") is the default.
- -JML 2006/6/21
- - If both shared and static libraries are installed, now both will be
- tested during 'make install'. -MAM 2006/06/21
- - Added support to explicity enable stream_vfd or shared libraries
- when using parallel via the '--enable-stream_vfd' and
- '--enable-shared' options, respectively. If not explicity defined,
- These settings default to enabled when parallel is not used,
- and disabled when parallel is used. -MAM 2006/06/17
- - Remove the flexible parallel code and the --enable-fphdf5
- configure option, it was never up to production standards
- anyway. -QAK 2006/4/20
- - Added a macro hdf5_mpi_special_collective_io_works to filter out
- some mpi-io packages that don't support collective IO for no IO
- contributions in some processes. -KY 2006/2/16
- - Added -shlib option to link against installed shared libraries to
- h5c++ and h5fc. -JML 2005/11/1
- - Added --enable-build-all option to configure, which only developers
- should need to use. -JML 2005/10/24
- - Configure uses the 'TR' variable to let the user override the path
- to the 'tr' utility. -JML 2005/10/17
- - Configure can recognize -lmpich as a form of MPI library. -AKC-
- 2005/9/28.
- - MD5 checksumming has been added to snapshot releases. Release
- tarballs will be accompanied by .md5 checksum files, which can
- be verified using the md5sum utility. -JML 2005/9/6
- - Some configure flags are incompatible (e.g., the C++ APIs cannot
- be built using the parallel version of HDF5). configure will now
- output errors when some common incompatible features are used
- together. -JML 2005/9/6
- - A new API function, H5Tis_hard(), was added to the library. It
- checks if a conversion function is a compiler (hard) conversion.
- SLU - 2005/9/6
- - t_mpi will run the test_mpio_derived_dtype by default unless it is
- known not working (indicated by macro H5_MPI_COMPLEX_DERIVED_DATATYPE_WORKS
- not defined.) -AKC- 2005/8/23.
- - Test execution has changed in a number of ways:
- When make is invoked in parallel (using -j), sequential tests
- are now executed as parallel make targets. This should make them
- finish more quickly on machines with multiple processors.
- Since test output is garbled when they are executed by parallel make,
- tests now dump their output to foo.log files and foo.logsh files
- (for test scripts). These logs are printed to the screen only
- when a test fails or when all tests in the current directory have
- completed successfully.
- When tests pass, they will create a foo.chkexe file.
- This prevents the test from executing again until the test or
- main library changes.
- All files generated by tests (*.chkexe, *.log, and any *.h5 files
- created) can be removed by invoking 'make check-clean'.
- Sequential and parallel library tests can now be invoked separately.
- 'make check-s' will execute only sequential tests, and 'make check-p'
- will execute only parallel tests. 'make check' will still execute
- all tests.
- -JML 2005/08/03
- - On windows, all.zip is deprecated. users should
- read INSTALL_Windows.txt to know the details.
- Reasons to deprecate all.zip:
- 1. Avoid confliction for windows programmers
- 2. Decrease size of CVS tree by adding all.zip
- 3. Avoid using winzip as the intermediate step
- --KY 2005/04/22
- - When HDF5 is created as a shared library, it now uses libtool's
- shared library versioning scheme. -JML 2005/04/18
- - HDF5 now uses automake 1.9.5 to generate Makefiles.in.
- This has a number of effects on users:
- The Fortran compiler should be set using the environment
- variable $FC, not $F9X. F9X still works, but is depreciated.
- The output of make may be different. This should be only a
- cosmetic effect.
- make depened (or make dep) is no longer recognized, since automake
- handles dependency tracking.
- Some new configure options exist. --enable-dependency-tracking
- and --disable-dependency-tracking are used to control automake's
- dependency tracking. Dependencies are on by default *on most
- platforms and compilers*. If --enable-dependency-tracking is
- used, they will be enabled on any platform. However, this can
- slow down builds or even cause build errors in some cases.
- Likewise, --disable-dependency-tracking can speed up builds and
- avoid some build errors.
- Some make targets have alternate names. make check-install and
- make installcheck do the same thing, for instance.
- pmake on IRIX can be invoked from the root directory, but the
- -V flag must be used to invoke it in any subdirectory or it
- will give an error about undefined variables.
- JML 2005/01 - 2005/03
- - Hardware conversion between long double and integers is also added.
- SLU 2005/02/10
- - Started to support software conversion between long double and
- integers. Hardware conversion will come very soon. SLU - 2005/1/6
- - Intel v8.0 compiler would infinite loop when compiling some test
- code with -O3 option. Changed enable-production default compiler
- option to -O2. AKC - 2004/12/06
- - Long double is assumed to be a supported C data type. It is a
- stanadard C89 type. AKC - 2004/10/22
- - The IA64 will use ecc as the C++ compiler by default.
- - Added some initial support for making valgrind/Purify (or similar
- memory checking products) happier by initializing buffers to zero
- and disabling the internal free list code. To take advantage of
- this, use the "--enable-using-memchecker" configure option when
- building the library. QAK - 2004/07/23
- - Fixed the long compile time of H5detect.c when v7.x Intel Compiler
- is used with optimization NOT off. AKC - 2004/05/20
- - Fixed configure setting of C++ for OSF1 platform. AKC - 2004/01/06
- - Prefix default is changed from /usr/local to `pwd`/hdf5.
- AKC - 2003/07/09
+ -------------
Library:
--------
- - Removed size restrictions on attributes, when using the "latest"
- version of the file format. - QAK - 2007/02/21
- - Relaxed restrictions on attribute operations to allow a file ID to
- be used as the "location ID". If a file ID is used, the attribute
- operation will occur on the root group of the file.
- - QAK - 2007/02/09
- - Enabled the CORE driver to read an existing file depending on
- the setting of the backing_store for H5Pset_fapl_core and file
- open flags. - SLU - 2006/11/30
- - Added new H5Gget_info_by_idx() routine to query the information about
- a group according to the order within an index.
- - QAK - 2006/11/27
- - Added new H5Gget_info() routine to query the information about a
- group by name.
- - QAK - 2006/11/27
- - Added new H5Oget_info_by_idx() routine to query the information about
- an object in a group according to the order within an index.
- - QAK - 2006/11/26
- - Added new H5Oget_info() routine to query the information about an
- object in a group by name.
- - QAK - 2006/11/26
- - Added new H5Oopen_by_idx() routine to open an object in a group
- according to the order within an index.
- - QAK - 2006/11/20
- - Added new H5Literate() routine to iterate over links in a group
- according to the order within an index.
- - QAK - 2006/11/20
- - Added new H5Ldelete_by_idx() routine to delete a link according to
- the order within an index.
- - QAK - 2006/11/13
- - Added new H5Lget_val_by_idx() routine to query the value of a soft link
- according to the order within an index.
- - QAK - 2006/11/13
- - Added new H5Lget_name_by_idx() routine to query the name of a link
- according to the order within an index.
- - QAK - 2006/11/12
- - Added new H5Rget_name() routine to determine the name of the object
- that a reference points to, as long as the object is still
- reachable in the group hierarchy.
- - QAK - 2006/11/10
- - Added new H5Lget_info_by_idx() routine to query the link information
- according to the order within an index.
- - QAK - 2006/11/10
- - Added feature to H5Iget_name to allow retrieving the name of any
- object's ID, as long as the object is still reachable in the
- group hierarchy.
- - LA - 2006/11/01
- - Added External and User-defined links.
- External links are links from one HDF5 file to another; they
- require both the name of the file and a path within that file.
- User-defined links allow users to supply callback functions
- for link traversals, allowing links to exhibit essentially
- any behavior.
- External links are a kind of user-defined link, so their default
- behavior can be overridden by the user.
- -JML 2006/8/23
- - Added H5Oopen and H5Oclose for opening objects of unknown type
- (as link callback functions do).
- -JML 2006/8/23
- - Added H5Oopen_by_addr, H5Oincr_refcount, and H5Odecr_refcount for
- opening objects by address. Be very careful with these!
- -JML 2006/8/23
- - Added H5Fget_intent to get the "intent" of a file (whether it
- was opened with read-write access or read-only.
- -JML 2006/8/23
- - Added Link Access Property Lists. They currently contain two
- properties, nlinks (H5Pget/set_nlinks) and elink_prefix
- (H5Pget/set_elink_prefix). nlinks controls how many soft and
- user-defined traversals are allowed before HDF5 assumes it has
- found a cycle (previously this defaulted to 16).
- The elink_prefix is a filesystem path that is prefixed to the
- names of any external link files opened using this LAPL.
- -JML 2006/8/23
- - Add H5L link APIs. Old APIs (H5Glink, H5Gmove, etc.) are still
- supported but deprecated.
- New APIs are:
- H5Llink - create a link to an object given its ID
- H5Lmove - just like H5Gmove2
- H5Lcopy - copy a link without copying the underlying object
- H5Lcreate_hard - like H5Glink2 for hard links
- H5Lcreate_soft - like H5Glink2 for soft links
- H5Ldelete - just like H5Gunlink
- H5Lget_val - just like H5Gget_linkval
- H5Lget_info - gets link-specific info (like H5Gget_objinfo)
-
- In addition, H5Gcreate_anon, H5Tcommit_anon, and H5Dcreate_anon
- no longer create links to objects; objects must be manually linked
- using H5Llink or they will be deleted when the ID is closed.
-
- Link Creation Property Lists can be used to pass character
- encoding (ASCII or UTF-8) for link names and to set the Intermediate
- Group Creation Flag:
- H5Pset_char_encoding, H5Pget_char_encoding
- H5Pset_copy_object, H5Pget_copy_object
- -JML 2006/7/5
- - Added managements of collective IO supports for chunking storage
- inside parallel HDF5
- 1) Implemented One IO with collective mode for all chunks in the
- application by building one MPI derived datatype accross all
- chunks.
- 2) Implemented the decision-making support to do collective IO inside
- MPI-IO per chunk.
- 3) Added the decision-making support to do one IO accross all chunks
- or to do multiple IOs with each IO per chunk.
- 4) Added the support to handle the case some processes won't do any IOs in
- collectively.
- 5) Some MPI-IO package(mpich 1.2.6 or lower, e.g.) cannot handle
- collective IO correctly for the case when some processes have no
- contributions to IOs, a special macro is added to change
- collective IO mode to independent IO mode inside HDF5 library.
-
- Currently we find that MPICH at Linux and vender MPI-IO package at NCSA
- Altix cannot handle this case.
-
- "hdf5_mpi_special_collective_io_works=${hdf5_mpi_special_collective_io_works='no'}"
- has been added at the end of file <ia64-linux-gnui> and
- <linux-gnulibc1>.
-
- If MPI-IO packages at your Linux and Altix support this case,
- please comment out the last line and report to us at
- help@hdfgroup.org. We can tune in our configuration to
- support this.
-
- KY - 2006/02/16
- - Added character encoding to attribute creation property lists.
- JML - 2006/01/02
- - Added H5Gcopy() routine to copy objects between while keeping
- data in compressed form. QAK - 2005/11/06
- - Added H5Sextent_equal() routine. QAK - 2005/11/06
- - Added HSYS_ERROR which retrieves the system error message and pushes
- it to the error stack. This gives more information of the failed
- system call. AKC - 2005/08/04
- - Added H5F_OBJ_LOCAL flag to H5Fget_obj_count() & H5Fget_obj_ids(), to
- allow querying for objects in file that were opened with a particular
- file ID, instead of all objects opened in file with any file ID.
- QAK - 2005/06/01
- - Added H5T_CSET_UTF8 character set to mark datatypes that use the
- UTF-8 Unicode character encoding. Added tests to ensure that
- library handles UTF-8 object names, attributes, etc. -JL 2005/05/13
- - HDF5 supports collective MPI-IO for irregular selection with HDF5
- dataset. Irregular selection is when users use H5Sselect_hyperslab
- more than once for the same dataset.
- Currently, not all MPI-IO packages support complicated MPI derived
- datatype used in the implementation of irregular
- selection INSIDE HDF5.
- 1) DEC 5.x is not supporting complicated derived datatype.
- 2) For AIX 5.1,
- if your poe version number is 3.2.0.19 or lower,
- please edit powerpc-ibm-aix5.x under hdf5/config,
- Find the line with
- << hdf5_mpi_complex_derived_datatype_works>>
- and UNCOMMENT this line before the configure.
- check poe version with the following command:
- lpp -l all | grep ppe.poe
- 3) For Linux cluster,
- if mpich version is 1.2.5 or lower, collective irregular selection
- IO is not supported, internally independent IO is used.
- 4) For IRIX 6.5,
- if C compiler version is 7.3 or lower, collective irregular selection
- IO is not supported, internally independent IO is used.
- 5) For platforms which internally used mpich, if the
- mpich version is 1.2.5 or lower, please find the
- corresponding config file and add
- hdf5_mpi_complex_derived_datatype_works='no' at the
- end of the configuration file. For example, at NCSA
- SGI Altix, the internal mpich library is 1.2.5. So
- hdf5_mpi_complex_derived_datatype_works='no' should be
- added at the end of the config file ia64-linux-gnu.
- KY - 2005/09/12
- We also found not all MPI-IO packages support collective IO with one
- or more processes to have no contributions to IO.
- For mpich version 1.2.6 or lower and all IRIX machine,
- if the library checks that there are no IO contributions for some
- processes, collective IO request is replaced with
- independent inside HDF5.
- KY - 2006/05/04
-
- - HDF5 N-bit filter
- HDF5 support N-bit filter from this version,
- The N-Bit filter is used effectively for compressing data of N-Bit
- datatype as well as compound and array datatype with N-Bit fields.
- KY - 2005/04/15
- - HDF5 scaleoffset filter
- HDF5 supports scaleoffset filter for users to do data
- compression through HDF5 library.
- Scale-Offset compression performs a scale and/or offset operation
- on each data value and truncates the resulting value to a minimum
- number of bits and then stores the data.
- Scaleoffset filter supports floating-point and integer datatype.
- Please check the HDF5 reference manual for this.
- KY - 2005/06/06
- - Retired SRB vfd (--with-srb). Functions H5Pset_fapl_srb and
- H5Pget_fapl_srb were removed. EIP - 2005/04/07
- - Retired GASS vfd (--with-gass). Functions H5Pset_fapl_gass and
- H5Pget_fapl_gass are removed too. AKC - 2005/3/3
- - Pablo was removed from the source code EIP - 2005/01/21
- - Modified registration of SZIP to dynamically detect the presence
- or absence of the encoder. Changed configure and Makefiles,
- and tests to dynamically detect encoder. BEM - 2004/11/02
- - Added function H5Pget_data_transform, together with the previously
- added H5Pset_data_transform, to support the data transform
- feature. AKC - 2004/10/26
- - Compound datatype has been enhanced with a new feature of size
- adjustment. The size can be increased and decreased(without
- cutting the last member) as long as it doesn't go down to zero.
- No API change is involved. SLU - 2004/10/1
- - Put back 6 old error API functions to be backward compatible with
- version 1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear,
- H5Eset_auto, H5Eget_auto. Their new equivalent functions are
- called H5Epush_stack, H5Eprint_stack, H5Ewalk_stack,
- H5Eclear_stack, H5Eset_auto_stack, H5Eget_auto_stack. SLU -
- 2004/9/2
- - 4 new API functions, H5Tencode, H5Tdecode, H5Sencode, H5Sdecode were
- added to the library. Given object ID, these functions encode and
- decode HDF5 objects(data type and space) information into and from
- binary buffer. SLU - 2004/07/21
- - Modified the way how HDF5 calculates 'pixels_per_scanline' parameter for
- SZIP compression. Now there is no restriction on the size and shape of the
- chunk except that the total number of elements in the chunk cannot be
- bigger than 'pixels_per_block' parameter provided by the user.
- EIP - 2004/07/21
- - Added support for SZIP without encoder. Added H5Zget_filter_info
- and changed H5Pget_filter and H5Pget_filter_by_id to support this
- change. JL/NF - 2004/06/30
- - SZIP always uses K13 compression. This flag no longer needs to
- be set when calling H5Pset_szip. If the flag for CHIP
- compression is set, it will be ignored (since the two are mutually
- exclusive). JL/NF - 2004/6/30
- - A new API function H5Fget_name was added. It returns the name
- of the file by object(file, group, data set, named data type,
- attribute) ID. SLU - 2004/06/29
- - Added support for user defined identifier types. NF/JL - 2004/06/29
- - A new API function H5Fget_filesize was added. It returns the
- actual file size of the opened file. SLU - 2004/06/24
- - New Feature of Data transformation is added. AKC - 2004/05/03.
- - New exception handler for datatype conversion is put in to
- replace the old overflow callback function. This exception
- handler is set through H5Pset_type_conv_cb function.
- SLU - 2004/4/27
- - Added option that if $HDF5_DISABLE_VERSION_CHECK is set to 2,
- will suppress all library version mismatch warning messages.
- AKC - 2004/4/14
- - A new type of dataspace, null dataspace(dataspace without any
- element) was added. SLU - 2004/3/24
- - Data type conversion(software) from integer to float was added.
- SLU - 2004/3/13
- - Data type conversion(software) from float to integer was added.
- Conversion from integer to float will be added later.
- SLU -2004/2/4
- - Added new H5Premove_filter routine to remove I/O pipeline filters
- from dataset creation property lists. PVN - 2004/01/26
- - Added new 'compare' callback parameter to H5Pregister & H5Pinsert
- routines. QAK - 2004/01/07
- - Data type conversion(hardware) between integers and floats was added.
- SLU 2003/11/21
- - New function H5Iget_file_id() was added. It returns file ID given
- an object(dataset, group, or attribute) ID. SLU 2003/10/29
- - Added new fields to the H5G_stat_t for more information about an
- object's object header. QAK 2003/10/06
- - Added new H5Fget_freespace() routine to query the free space in a
- given file. QAK 2003/10/06
- - Added backward compatability with v1.6 for new Error API. SLU -
- 2003/09/24
- - Changed 'objno' field in H5G_stat_t structure from 'unsigned long[2]'
- to 'haddr_t'. QAK - 2003/08/08
- - Changed 'fileno' field in H5G_stat_t structure from 'unsigned long[2]'
- to 'unsigned long'. QAK - 2003/08/08
- - Changed 'hobj_ref_t' type from structure with array field to 'haddr_t'.
- QAK - 2003/08/08
- - Object references (hobj_ref_t) can now be compared with the 'objno'
- field in the H5G_stat_t struct for testing if two objects are the
- same within a file. QAK - 2003/08/08
- - Switched over to new error API. SLU - 2003/07/25
Parallel Library:
-----------------
- - Added mpich2 as a testing "platform" informally. AKC - 2005/9/28.
- - A dataset created in serial mode with H5D_ALLOC_TIME_INCR allocation
- setting was not extendible, either explicitly by H5Dextend or
- implicitly by writing to unallocated chunks. Library now allocates
- more space when needed or directed if the file is opened by parallel
- mode, independent of what the dataset allocation mode is.
- CC/AKC - 2005/08/29.
- - Allow compressed, chunked datasets to be read in parallel.
- QAK - 2004/10/04
- - Add options of using atomicity and file-sync to test_mpio_1wMr.
- AKC - 2003/11/13
- - Added parallel test, test_mpio_1wMr, which tests if the
- underlaying parallel I/O system is conforming to the POSIX
- write/read requirement. AKC - 2003/11/12
Fortran Library:
----------------

- - added missing h5tget_member_class_f function
- EIP 2005/04/06
- - added new functions h5fget_name_f and h5fget_filesize_f
- EIP 2004/07/08
- - h5dwrite/read_f and h5awrite/read_f functions only accept dims parameter
- of the type INTEGER(HSIZE_T).
- - added support for native integers of 8 bytes (i.e. when special
- compiler flag is specified to set native fortran integers to 8 bytes,
- for example, -i8 flag for PGI and Absoft Fortran compilers,
- -qintsize=8 flag for IBM xlf compiler).
- EIP 2005/06/20
- - added support for "big" REAL and DOUBLE PRECISION types
- (usually the size is specified by compilers flags like
- -r8, -r16, etc.)
- Known problem: multi file test fails when REAL is 16 bytes.
- EIP 2005/09/8
C++ Library:
----------------
- - added support for shared C++ libraries. -JML 2005/09/20
- - Added missing member functions
- H5::CompType::getMemberArrayType
- H5::CompType::getMemberVarLenType
- H5::AbstractDs::getArrayType
- H5::AbstractDs::getVarLenType
- H5::CommonFG::openArrayType
- H5::CommonFG::openVarLenType
- H5::PropList::copyProp -- this will replace the current
- H5::PropList::copyProp in later releases due
- to incorrect prototype.
- H5::IdComponent::getHDFObjType
- BMR - 2005/08/08

==================================
Library
-------
- - Changed library's behavior for reading files that might have
- corrupted object header information from a previous (buggy)
- version of the library. By default, the library now rebuilds the
- correct object header information instead of issuing an error.
- Previous "strict" file format interpretation can be enabled with
- the "--enable-strict-format-checks" configure option.
- QAK - 2008/01/13
- - Fixed several bugs with writing fill values for datasets that have
- a variable-length datatype or component datatype. QAK - 2007/06/19
- - STDIO driver didn't support files bigger than 2GB because the OFFSET
- parameter of fseek is of type LONG INT, not big enough for big files.
- Use fseeko instead for big files if it's available on the system.
- SLU - 2007/4/5
- - Fixed a bug in H5Sselect_valid() that caused an incorrect value to
- be returned (0) instead of FAIL on error conditions such as the
- selection or extent not being defined. CMC - 2007/01/17
- - Fixed the MULTI driver problem (Bug #731) that corruptted the data.
- SLU - 2007/1/12
- - Fixed file corruption bug which could write an incorrect number of
- messages to an object's header under certain circumstances.
- Generally, the sequence of actions to generate this bug looks
- like this:
- - Create an object
- - Close the file
- - Re-open the file
- - Add 2 (or more) attributes to the object
- - Close the file
- - Re-open the file
- - Delete one of the attributes on the object
- - Add a smaller attribute to the object
- - Delete the smaller atttribute on the object
- - Add a larger attribute on the object
-
- After this, the number of header messages stored for the object
- will be off by one. Other sequences of modifying attributes on an
- object could also trigger this bug. If you are opening an
- object and the bottom few messages of the HDF5 error stack
- resembles this, the object has been affected by this bug:
-
- #007: ../../hdf5_v1.6/src/H5C.c line 3887 in H5C_load_entry(): unable to load entry
- major(08): Meta data cache layer
- minor(40): Unable to load metadata into cache
- #008: ../../hdf5_v1.6/src/H5Ocache.c line 332 in H5O_load(): corrupt object header - too few messages
- major(12): Object header layer
- minor(40): Unable to load metadata into cache
-
- Specifically, "corrupt object header" is the best string to search
- for in the HDF5 error stack output.
-
- If your files have been affected by this bug, or you are concerned
- that your files might have been, please contact the HDF Helpdesk
- at help@hdfgroup.org for a tool to detect and repair files
- affected by this problem. QAK - 2006/6/16
- - Fixed various problems with retrieving names of objects, especially
- with mounted files. QAK - 2005/12/25
- - Fixed core dump when closing root groups opened through two different
- file handles that operate on the same actual file. QAK - 2005/10/02
- - Corrected errors when performing various operations on a group opened
- by dereferencing an object reference. QAK - 2005/07/30
- - Fixed a bug with named datatypes where a copy of a named datatype
- used to create a dataset would accidentally use the original
- named datatype for the dataset's datatype. QAK - 2005/07/23
- - Made H5Fget_name() be consistent and always return name of actual
- file the ID is in. (Instead of the name of the top file in a
- file mounting hierarchy). QAK - 2005/07/19
- - Reworked internal file mounting semantics to hopefully eliminate
- mounting problems. We now require that files that are mounting
- together all have the same "file close degree". QAK - 2005/07/19
- - More bug fixes on holding open files that are mounted and have
- IDs open. QAK - 2005/07/14
- - Don't unmount child files until the parent file actually closes.
- (Previously, if an object is holding open a file, the child files
- would get unmounted too early). QAK - 2005/07/05
- - Fixed bug where unmounted files could cause the library to go into
- an infinite loop when shutting down. QAK - 2005/06/30
- - The library didn't save the information of family driver in file.
- The original file member size was lost after file was closed (see
- bug #213). This has been fixed by saving driver name and member
- file size in the superblock. SLU - 2005/6/24
- - Fixed bug with hyperslab selections that use selection offsets and
- operate on chunked datasets going into infinite loop or dumping
- core. QAK - 2005/06/17
- - Corrected memory leak and possible corruption when opening a group.
- QAK - 2005/06/17
- - Added check for opaque datatype tags being too long (check against
- H5T_OPAQUE_TAG_MAX, currently set to 256). QAK - 2005/06/14
- - Fixed various errors in maintaining names for open objects in the
- face of unusual mount & unmount operations. QAK - 2005/06/08
- - "SEMI" and "STRONG" file close degree settings now apply only to the
- particular file ID being closed, instead of operating on all open
- file IDs for a given file. QAK - 2005/06/01
- - For family driver, the library didn't save member size in file.
- When file is reopened, the size of 1st member file determine the
- member size. Now member size is saved in file and is used to
- define member file size. Wrong file access property of member size
- will result in a failure. Using any other driver except family
- will cause library to return error. So is multi driver. SLU -
- 2005/05/24
- - Fixed error in opening object in group that was opened in mounted
- file which has been unmounted. QAK - 2005/03/17
- - Fixed a racing condition in MPIPOSIX virtual file drive close
- function. Now all processes must completed the close before any
- of them is returned. This prevents some "faster" processes start
- accessing the file for another purpose (e.g., open with truncate)
- while other "slower" processes have not closed the same file with
- the previous purpose. AKC - 2005/03/01
- - H5Tget_member_value calls for enum datatype didn't return correct
- value if H5Tenum_valueof was called first. It's fixed. SLU -
- 2005/02/08
- - For variable-length string, H5Tget_class returned H5T_STRING as its
- class. But H5Tdetect_class and H5Tget_member_class considered it
- as H5T_VLEN. This is fixed to let all these 3 functions treat it
- as H5T_STRING. SLU - 2005/02/08
- - The byte order of 1-byte integer types was fixed as little endian
- even on a big-endian machine. This has been corrected. SLU -
- 2005/02/07
- - Fix segmentation fault when calling H5Fflush with an attribute that
- hasn't had a value written to it open. QAK - 2004/10/18
- - Back up supporting bitfield and time types in H5Tget_native_type.
- Leave it to future support. The function simply returns error
- message of "not support" for bitfield and time types.
- SLU - 2004/10/5
- - Fixed address check in Core VFL driver to avoid spurious address/size
- overflows for odd valued addresses and/or sizes. QAK - 2004/09/27
- - Fixed parallel bug in which some processes attempted collective
- I/O while others did independent I/O. Bug appeared when some
- processes used point selections, and others didn't. JRM - 2004/9/15
- - Corrected error where dataset region references were written in an
- incorrect way on Cray machines. PVN & QAK - 2004/09/13
- - The H5Tget_native_type now determines the native type for integers
- based on the precision. This is to avoid cases of wrongly converting
- an int to a short in machines that have a short of 8 bytes but with
- 32bit precision (e.g Cray SV1). PVN - 2004/09/07
- - Changed H5Dread() to not overwrite data in an application's buffer
- with garbage when accessing a chunked dataset with an undefined
- fill value and an unwritten chunk is uncountered. QAK - 2004/08/25
- - Fixed error which could cause a core dump when a type conversion
- routine was registered after a compound datatype had been
- converted and then an equivalment compound datatype was converted
- again. QAK - 2004/08/07
- - Fixed memory overwrite when encoding "multi" file driver information
- for file's superblock. QAK - 2004/08/05
- - Fixed obscure bug where a filter which failed during chunk allocation
- could allow library to write uncompressed data to disk but think
- the data was compressed. QAK - 2004/07/29
- - Fixed bug where I/O to an extendible chunked dataset with zero-sized
- dimensions would cause library to fail an assertion.
- QAK - 2004/07/27
- - Fixed bug where chunked datasets which have filters defined,
- allocation time set to "late" and whose chunks don't align with
- the dataspace bounds could have incorrect data stored when
- overwriting the entire dataset on the first write. QAK - 2004/07/27
- - Added check to ensure that dataspaces have extents set. JML-2004/07/26
- - Fixed bug on some Solaris systems where HDF5 would try to use
- gettimeofday() when that function didn't work properly.
- JML - 2004/07/23
- - Fixed bug in H5Sset_extent_simple where setting maximum size to
- non-zero, then to zero would cause an error. JML - 2004/07/20
- - Allow NULL pointer for buffer parameter to H5Dread & H5Dwrite
- when not writing data ("none" selection or hyperslab or point
- selection with no elements defined). QAK - 2004/07/20
- - Calling H5Gcreate() on "/" or "." throws an error instead of
- failing quietly. JML - 2004/07/19
- - Fixed bug where setting file address size to be very small could
- trigger an assert if the file grew to more than 64 KB. Now throws
- an error and data can be recovered. JL/NF - 2004/07/14
- - Fixed bug where "resurrecting" a dataset was failing.
- QAK - 2004/07/14
- - Fixed bug where incorrect data could be read from a chunked dataset
- after it was extended. QAK - 2004/07/12
- - Fixed failure to read data back from file of compound type with
- variable-length string as field. SLU - 2004/06/10
- - Fixed potential file corruption bug when a block of metadata could
- overlap the end of the internal metadata accumulator buffer and
- the buffer would be extended correctly, but would incorrectly
- change it's starting address. QAK - 2004/06/09
- - Opaque datatype with no tag failed for some operations. Fixed.
- SLU - 2004/6/3
- - Fixed potential file corruption bug where dimensions that were
- too large (a value greater than could be represented in 32-bits)
- could cause the incorrect amount of space to be allocated in a
- file for the raw data for the dataset. QAK - 2004/06/01
- - Fixed dtypes "sw long double -> double" failure in QSC class
- machines. AKC - 2004/4/16
- - Fixed problem with fletcher32 filter when converting data of different
- endianess. PVN - 2004/03/10
- - Fixed problem with H5Tget_native_type() not handling opaque fields
- correctly. QAK - 2004/01/31

- with the right sequence of deleted objects. QAK - 2004/01/19
- - Fixed small internal memory leaks of fill-value information.
- QAK - 2004/01/13
- - Fixed bug that caused variable-length datatypes (strings or sequences)

- fail to be read/written to a file. QAK - 2004/01/13
- - Detect situation where szip 'pixels per block' is larger than the
- fastest changing dimension of a dataset's chunk size and disallow
- this (due to limits in szip library). QAK - 2003/12/31
- - Fixed bug with flattened hyperslab selections that would generate
- incorrect hyperslab information with certain high-dimensionality
- combinations of start/stride/count/block information.
- QAK - 2003/12/31
- - Fixed bug with variable-length datatypes used in compound datatypes.
- SLU - 2003/12/29
- - Fixed bug in parallel I/O routines that would cause reads from
- "short datasets" (datasets which were only partially written out)
- to return invalid data. QAK & AKC - 2003/12/19
- - Fixed bug where scalar dataspaces for attributes were reporting as
- simple dataspaces. QAK - 2003/12/13
- - Fixed problem with selection offsets of hyperslab selections in
- chunked datasets causing the library to go into an infinite loop.
- QAK - 2003/12/13
- - Fixed H5Giterate to avoid re-using index parameter after iteration
- callback has been called (allows iteration callback to modify the
- index parameter itself). QAK - 2003/12/06
- - Fixed various floating-point conversion problems, including a
- change which could corrupt data when converting from double->float.
- QAK - 2003/11/24
- - Changed "single process" metadata writing in library to collective
- I/O by all processes, in order to guarantee correct data being
- written with MPI-I/O. QAK - 2003/11/20

- - Removed HDF5_MPI_PREFER_DERIVED_TYPES environment variable support,
- since it had no benefit. QAK - 2003/10/28
- - Single hyperslab selections (which were set with only one call to
- H5Sselect_hyperslab) that had dimensions that could be "flattened"
- but were interspersed with dimensions that could not be flattened
- were not correctly handled, causing core dumps. QAK - 2003/10/25
- - Fixed incorrect datatype of the third parameter to the Fortran90
- h5pset(get)_cache_f subroutine (INTEGER to INTEGER(SIZE_T))
- EIP - 2003/10/13
- - Fixed problems with accessing variable-length data datatypes on
