From 19044cbbb88ff40f96df17e10413213d0726d409 Mon Sep 17 00:00:00 2001 From: Frank Baker Date: Fri, 2 Feb 2001 16:45:09 -0500 Subject: [svn-r3344] Purpose: Extracting RELEASE and HISTORY from Changes.html and distributing them as separate files will not only leave Changes.html easier to read, but will ease maintenance. Solution: Removed the RELEASE and HISTORY files' contents from Changes.html, inserting links instead. Changes.html now points to RELEASE.txt and HISTORY.txt, duplicates of hdf5/RELEASE and hdf5/HISTORY. These two files will henceforth be distributed within the doc set so that this information can be available to applications developers who cannot access the HDF website (e.g., due to a firewall) and are working without the HDF5 source code.

-New Features
-============
-   * The Virtual File Layer, VFL, was added to replace the old file
-     drivers. It also provides an API for user defined file drivers.
-   * New features added to snapshots. Use 'snapshot help' to see a
-     complete list of features.
-   * Improved configure to detect if MPIO routines are available when
-     parallel mode is requested.
-   * Added Thread-Safe support. Phase I implemented.
-   * Added data sieve buffering to raw data I/O path. This is enabled
-     for all VFL drivers except the mpio & core drivers. Setting the
-     sieve buffer size is controlled with the new API function,
-     H5Pset_sieve_buf_size(), and retrieved with H5Pget_sieve_buf_size().
-   * Added new Virtual File Driver, Stream VFD, to send/receive entire
-     HDF5 files via socket connections.
-   * As parts of VFL, HDF-GASS and HDF-SRB are also added to this
-     release. To find out details, please read INSTALL_VFL file. 
-   * Increased maximum number of dimensions for a dataset (H5S_MAX_RANK)
-     from 31 to 32 to align with HDF4 & netCDF.
-   * Added 'query' function to VFL drivers.  Also added 'type' parameter to
-     VFL 'read' & 'write' calls, so they are aware of the type of data
-     being accessed in the file.  Updated the VFL document also.
-   * A new h4toh5 uitlity, to convert HDF4 files to analogous HDF5 files.
-   * Added a new array datatype to the datatypes which can be created.  Removed
-     "array fields" from compound datatypes (use an array datatype instead).
-   * Parallel HDF5 works correctly with mpich-1.2.1 on Solaris, SGI, Linux.
-
-h4toh5 Utility 
-==============
-
-    The h4toh5 utility is a new utility that converts an HDF4 file to an 
-    HDF5 file.  For details, see the document, "Mapping HDF4 Objects to 
-    HDF5 Objects":
-       http://hdf.ncsa.uiuc.edu/HDF5/papers/H4-H5MappingGuidelines.pdf
-
-    Known Limitations of the h4toh5 beta release
-    ---------------------------------------------
-
-    1. Error Handling
-
-    Error reporting is minimal.
-
-    2. String Datatype
-
-    HDF4 has no 'string' type. String valued data are usually defined as
-    an array of 'char' in HDF4. The h4toh5 utility will generally map
-    these to HDF5 'String' types rather than array of char, with the
-    following additional rules:
-
-       * For the data of an HDF4 SDS, image, and palette, if the data is
-	 declared 'DFNT_CHAR8' it will be assumed to be integer and
-	 will be an H5T_INTEGER type.
-       * For attributes of any HDF4 object, data of type 'DFNT_CHAR8'
-	 will be converted to an HDF5 'H5T_STRING' type.
-       * For an HDF4 Vdata, it is difficult to determine whether data 
-	 of type 'DFNT_CHAR8' is intended to be bytes or characters.
-	 The h4toh5 utility will consider them to be C characters, and
-	 will convert them to an HDF5 'H5T_STRING' type.
-
-
-    3. Compression, Chunking and External Storage
-
-    Chunking is supported, but compression and external storage is not.
-
-    An HDF4 object that uses chunking will be converted to an HDF5 file
-    with analogous chunked storage.
-
-    An HDF4 object that uses compression will be converted to an
-    uncompressed HDF5 object.  
-
-    An HDF4 object that uses external storage will be converted to an
-    HDF5 object without external storage.  
-
-    4. Memory Use
-
-    The beta version of the h4toh5 utility copies data from HDF4 objects
-    in a single read followed by a single write to the HDF5 object. For
-    large objects, this requires a very large amount of memory, which may
-    be extremely slow or fail on some platforms.
-
-    Note that a dataset that has only been partly written will
-    be read completely, including uninitialized data, and all the
-    data will be written to the HDF5 object.
-
-    5. Platforms
-
-    The h4toh5 utility requires HDF5.1.4.
-
-    The beta h4toh5 utility has been tested on Solaris 2.6, Solaris 2.5,
-    Irix 6.5, HPUX 11.0, DEC Unix, FreeBSD, and Windows 2000.
-
-F90 Support
-===========
- 
-    This is the first release of the HDF5 Library with fully integrated 
-    F90 API support.  The Fortran Library is created when the 
-    --enable-fortran flag is specified during configuration.
-
-    Not all F90 subroutines are implemented. Please refer to the HDF5 
-    Reference Manual for more details.
-   
-    F90 APIs are available for the Solaris 2.6 and 2.7, Linux, DEC UNIX, 
-    T3E, J90 and O2K (64 bit option only) platforms. The Parallel version of 
-    the HDF5 F90 Library is supported on the O2K and T3E platforms.
-
-    Changes since the last prototype release (July 2000)
-    ----------------------------------------------------
-
-       * h5open_f and h5close_f must be called instead of h5init_types and 
-         h5close_types.
-
-       * The following subroutines are no longer available: 
-             h5pset_xfer_f
-             h5pget_xfer_f
-             h5pset_mpi_f
-             h5pget_mpi_f
-             h5pset_stdio_f
-             h5pget_stdio_f
-             h5pset_sec2_f
-             h5pget_sec2_f
-             h5pset_core_f
-             h5pget_core_f
-             h5pset_family_f
-             h5pget_family_f
-             
-       * The following functions have been added:
-             h5pset_fapl_mpio_f
-             h5pget_fapl_mpio_f
-             h5pset_dxpl_mpio_f
-             h5pget_dxpl_mpio_f
-        
-       * In the previous HDF5 F90 releases, the implementation of object 
-         references and dataset region references was not portable. This 
-         release introduces a portable implementation, but it also introduces 
-         changes to the read/write APIs that handle references.  If object or 
-         dataset region references are written or read to/from an HDF5 file, 
-         h5dwrite_f and h5dread_f must use the extra parameter, n, for the 
-         buffer size:
-
-            h5dwrite(read)_f(dset_id, mem_type_id, buf, n, hdferr, &
-                                                       ^^^ 
-                             mem_space_id, file_space_id, xfer_prp)
-
-         For other datatypes the APIs were not changed. 
-              
-             
-C++ Support
-===========
-
-        This is the first release of the HDF5 Library with fully integrated 
-        C++ API support. The HDF5 C++ library is built when the --enable-cxx
-        flag is specified during configuration.
-
-        Check the HDF5 Reference Manual for available C++ documentation.
-
-        C++ APIs are available for Solaris 2.6 and 2.7, Linux, and FreeBSD. 
- 
-
-Bug Fixes since HDF5-1.2.0
-==========================
-
-Library
--------
-
-   * The function H5Pset_mpi is renamed as H5Pset_fapl_mpio.
-   * Corrected a floating point number conversion error for the Cray J90
-     platform. The error did not convert the value 0.0 correctly.
-   * Error was fixed which was not allowing dataset region references to
-     have their regions retrieved correctly.
-   * Corrected a bug that caused non-parallel file drivers to fail in
-     the parallel version.
-   * Added internal free-lists to reduce memory required by the library
-     and H5garbage_collect API function
-   * Fixed error in H5Giterate which was not updating the "index"
-     parameter correctly.
-   * Fixed error in hyperslab iteration which was not walking through the
-     correct sequence of array elements if hyperslabs were staggered in a
-     certain pattern
-   * Fixed several other problems in hyperslab iteration code.
-   * Fixed another H5Giterate bug which was causes groups with large
-     numbers of objects in them to misbehave when the callback function
-     returned non-zero values.
-   * Changed return type of H5Aiterate and H5A_operator_t typedef to be
-     herr_t, to align them with the dataset and group iterator functions.
-   * Changed H5Screate_simple and H5Sset_extent_simple to not allow
-     dimensions of size 0 with out the same dimension being unlimited.
-   * QAK - 4/19/00 - Improved metadata hashing & caching algorithms to
-     avoid many hash flushes and also remove some redundant I/O when
-     moving metadata blocks in the file.
-   * The "struct(opt)" type conversion function which gets invoked for
-     certain compound datatype conversions was fixed for nested compound
-     types. This required a small change in the datatype conversion
-     function API.
-   * Re-wrote lots of the hyperslab code to speed it up quite a bit.
-   * Added bounded garbage collection for the free lists when they run
-     out of memory and also added H5set_free_list_limits API call to
-     allow users to put an upper limit on the amount of memory used for
-     free lists.
-   * Checked for non-existent or deleted objects when dereferencing one
-     with object or region references and disallow dereference.
-   * "Time" datatypes (H5T_UNIX_D*) were not being stored and retrieved
-     from object headers correctly, fixed now.
-   * Fixed H5Dread or H5Dwrite calls with H5FD_MPIO_COLLECTIVE requests
-     that may hang because not all processes are transfer the same amount
-     of data. (A.K.A. prematured collective return when zero amount data
-     requested.) Collective calls that may cause hanging is done via the
-     corresponding MPI-IO independent calls.
-
-Configuration
--------------
-
-   * The hdf5.h include file was fixed to allow the HDF5 Library to be
-     compiled with other libraries/applications that use GNU autoconf. 
-   * Configuration for parallel HDF5 was improved. Configure now attempts
-     to link with libmpi.a and/or libmpio.a as the MPI libraries by
-     default. It also uses "mpirun" to launch MPI tests by default. It
-     tests to link MPIO routines during the configuration stage, rather
-     than failing later as before. One can just do "./configure
-     --enable-parallel" if the MPI library is in the system library.
-   * Added support for pthread library and thread-safe option.
-   * The libhdf5.settings file shows the correct machine byte-sex.
-   * Added option "--enable-stream-vfd" to configure w/o the Stream VFD.
-     For Solaris, added -lsocket to the LIBS list of libraries.
-
-Tools
------
-    * h5dump now accepts both short and long command-line parameters. A
-      change from the old way is that multiple attributes, datasets,
-      groups, soft-links, and object-ids cannot be specified with just
-      one flag but you have to use a flag with each object. I.e., instead
-      of doing this:
-
-        h5dump -a /attr1 /attr2 foo.h5
-
-      do this:
-
-        h5dump -a /attr1 -a /attr2 foo.h5
-
-      The cases are similar for the other object types.
-    * h5dump correctly displays compound datatypes.
-    * Corrected an error in h5toh4 which did not convert the 32bits
-      int from HDF5 to HDF4 corectly for the T3E platform.
-    * h5dump correctly displays the committed copy of predefined types
-      correctly.
-    * Added an option, -V, to show the version information of h5dump.
-    * Fixed a core dumping bug of h5toh4 when executed on platforms like 
-      TFLOPS.
-    * The test script for h5toh4 used to not able to detect the hdp
-      dumper command was not valid.  It now detects and reports the
-      failure of hdp execution.
-    * Merged the tools with the 1.2.2 branch. Required adding new
-      macros, VERSION12 and VERSION13, used in conditional compilation.
-      Updated the Windows project files for the tools.            
-    * h5dump displays opaque and bitfield data correctly.
-    * h5dump and h5ls can browse files created with the Stream VFD
-      (eg. "h5ls :").
-    * h5dump has a new feature "-o " which outputs the raw data
-      of the dataset into ascii text file .
-    * h5toh4 used to converts hdf5 strings type to hdf4 DFNT_INT8 type.
-      Corrected to produce hdf4 DFNT_CHAR type instead.
-    * h5dump and h5ls displays array data correctly.
-
-Documentation
--------------
-
-    * User's Guide and Reference Manual were updated. 
-      See doc/html/PSandPDF/index.html for more details. 
-
-   
-Bug Fixes since HDF5-1.4.0-beta2
-================================
-
-    * Corrected configuration error which was not including compression support
-        correctly.
-    * Cleaned up lots of warnings.
-    * Changed a few h5dump command line switches and added long versions of
-        the switches.

-
-Known Problems
-==============
-
-* When building the HDF5 test project on Windows NT 4.0 (testhdf5
-  and testhdf5dll), the compiler fails to compile tvstr.c within
-  the whole project; however, when separately selecting the 
-  tvstr.c source code, it passes the compiler and everything that
-  depends on tvstr.obj links correctly.
-
-* h4toh5 fails on object references on the Cray T3E.
-
-* The installation of the DEC Fortran binaries fails.  It can be
-  done manually by copying the *.mod files from the fortran/src
-  directory.
-
-* Fortran modules are not installed when created. This should be done
-  manually by copying the modules from the fortran/src directory.
-
-* SunOS 5.6 with C WorkShop Compilers 4.2:  Hyperslab selections will 
-  fail if library is compiled using optimization of any level.
-
-* The Stream VFD was not tested yet under Windows.
-  It is not supported in the TFLOPS machine.
-
-* Shared library option is broken for IBM SP and some Origin 2000 platforms.
-  One needs to run ./configure with '--disable-shared'
-
-* 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:
-    - Solaris x86 2.5.1, Cray T3E and Cray J90 give errors during testing
-        when displaying object references in certain files.  These are benign 
-        differences due to the difference in sizes of the objects created on
-        those platforms.  h5ls appears to be dumping object references
-        correctly.
-    - Cray J90 (and Cray T3E?) 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.

-==========================
-
-Configuration
--------------
-
-   * The hdf5.h include file was fixed to allow the HDF5 Library to be compiled
-     with other libraries/applications that use GNU autoconf. 
-   * Configuration for parallel HDF5 was improved. Configure now attempts to
-     link with libmpi.a and/or libmpio.a as the MPI libraries by default.
-     It also uses "mpirun" to launch MPI tests by default.  It tests to
-     link MPIO routines during the configuration stage, rather than failing
-     later as before.  One can just do "./configure --enable-parallel"
-     if the MPI library is in the system library.
-
-Library
--------
-
-   * Error was fixed which was not allowing dataset region references to have
-     their regions retrieved correctly.
-   * Added internal free-lists to reduce memory required by the library and
-     H5garbage_collect API function
-   * Fixed error in H5Giterate which was not updating the "index" parameter
-     correctly.
-   * Fixed error in hyperslab iteration which was not walking through the
-     correct sequence of array elements if hyperslabs were staggered in a
-     certain pattern

-   --------------
-
-* NT alpha 4.0
-  Dumper utiliy h5dump fails if linked with DLL.
-
-* SunOS 5.6 with C WorkShop Compilers 4.2
-  Hyperslab selections will fail if library is compiled using optimization
-  of any level.
-
- 
-C. Changes Since Version 1.0.1
-   ---------------------------
-
-1. Documentation
-   -------------
-
-* More examples
-
-* Updated user guide, reference manual, and format specification.
-
-* Self-contained documentation for installations isolated from the
-  Internet.
-
-* HDF5 Tutorial was added to the documentation  
-
-2. Configuration
-   -------------
-
-* Better detection and support for MPI-IO.
-
-* Recognition of compilers with known code generation problems.
-
-* Support for various compilers on a single architecture (e.g., the
-  native compiler and the GNU compilers).
-
-* Ability to build from read-only media and with different compilers
-  and/or options concurrently.
-
-* Added a libhdf5.settings file which summarizes the configuration
-  information and is installed along with the library.
-
-* Builds a shared library on most systems that support it.
-
-* Support for Cray T3E, J90 and Windows/NT.
-
-3. Debugging
-   ---------
-
-* Improved control and redirection of debugging and tracing messages.
-
-4. Datatypes
-   ---------
-
-* Optimizations to compound datatype conversions and I/O operations.
-
-* Added nearly 100 optimized conversion functions for native datatypes 
-  including support for non-aligned data.
-
-* Added support for bitfield, opaque, and enumeration types.
-
-* Added distinctions between signed and unsigned char types to the
-  list of predefined native hdf5 datatypes.
-
-* Added HDF5 type definitions for C9x types like int32_t.
-
-* Application-defined type conversion functions can handle non-packed
-  data.
-
-* Changed the H5Tunregister() function to use wildcards when matching
-  conversion functions.  H5Tregister_hard() and H5Tregister_soft()
-  were combined into H5Tregister().
-
-* Support for variable-length datatypes (arrays of varying length per
-  dataset element). Variable length strings currently supported only
-  as variable length arrays of 1-byte integers.
-
-5. Dataspaces
-   ----------
-
-* New query functions for selections.
-
-* I/O operations bypass the stripmining loop and go directly to
-  storage for certain contiguous selections in the absense of type
-  conversions.  In other cases the stripmining buffers are used more
-  effectively.
-
-* Reduced the number of I/O requests under certain circumstances,
-  improving performance on systems with high I/O latency.
-
-6. Persistent Pointers
-   -------------------
-
-* Object (serial and parallel) and dataset region (serial only)
-  references are implemented.
-
-7. Parallel Support
-   ----------------
-
-* Improved parallel I/O performance.
-
-* Supported new platforms: Cray T3E, Linux, DEC Cluster.
-
-* Use vendor supported version of MPIO on SGI O2K and Cray platforms.
-
-* Improved the algorithm that translates an HDF5 hyperslab selection
-  into an MPI type for better collective I/O performance.

-  versions.
-
-* h5toh4: An hdf5 to hdf4 converter.
-
-
-
-III. Changes Since The Version 1.0.0 Release
-
-* [Improvement]: configure sets up the Makefile in the parallel tests
-  suit (testpar/) correctly.
-
-* [Bug-Fix]: Configure failed for all IRIX versions other than 6.3.
-  It now configures correctly for all IRIX 6.x version.
-
-* Released Parallel HDF5 
-
-     Supported Features:
-     ------------------
-
-     HDF5 files are accessed according to the communicator and INFO
-     object defined in the property list set by H5Pset_mpi.
-
-     Independent read and write accesses to fixed and extendable dimension
-     datasets.
-
-     Collective read and write accesses to fixed dimension datasets.
-
-     Supported Platforms:
-     -------------------
-
-     Intel Red
-     IBM SP2
-     SGI Origin 2000
-
-     Changes In This Release: 
-     -----------------------
-
-   o Support of Access to Extendable Dimension Datasets.
-     Extendable dimension datasets must use chunked storage methods.
-     A new function, H5Dextend, is created to extend the current
-     dimensions of a dataset.  The current release requires the
-     MPI application must make a collective call to extend the
-     dimensions of an extendable dataset before writing to the
-     newly extended area.  (The serial does not require the
-     call of H5Dextend.  The dimensions of an extendable
-     dataset is increased when data is written to beyond the
-     current dimensions but within the maximum dimensions.)
-     The required collective call of H5Dextend may be relaxed
-     in future release.
-
-     This release only support independent read and write accesses
-     to extendable datasets.  Collective accesses to extendable
-     datasets will be implemented in future releases.
-
-   o Collective access to fixed dimension datasets.
-     Collective access to a dataset can be specified in the transfer
-     property list argument in H5Dread and H5Dwrite.  The current
-     release supports collective access to fixed dimension datasets.
-     Collective access to extendable datasets will be implemented in
-     future releases.
-
-   o HDF5 files are opened according to Communicator and INFO object.
-     H5Dopen now records the communicator and INFO setup by H5Pset_mmpi
-     and pass them to the corresponding MPIO open file calls for
-     processing.
-
-   o This release has been tested on IBM SP2, Intel Red and SGI Origin 2000
-     systems.  It uses the ROMIO version of MPIO interface for parallel
-     I/O supports.
-
-
-
-IV. Changes Since The Beta 1.0.0 Release
-
-* Added fill values for datasets.  For contiguous datasets fill value
-  performance may be quite poor since the fill value is written to the 
-  entire dataset when the dataset is created.  This will be remedied
-  in a future version.  Chunked datasets using fill values do not
-  incur any additional overhead. See H5Pset_fill_value().
-
-* Multiple hdf5 files can be "mounted" on one another to create a
-  larger virtual file. See H5Fmount().
-
-* Object names can be removed or changed but objects are never
-  actually removed from the file yet. See H5Gunlink() and H5Gmove().
-
-* Added a tuning mechanism for B-trees to insure that sequential
-  writes to chunked datasets use less overhead.  See H5Pset_btree_ratios().
-
-* Various optimizations and bug fixes.
-
-
-V. Changes Since The Second Alpha 1.0.0 Release
-
-* Strided hyperslab selections in dataspaces now working.
-
-* The compression API has been replaced with a more general filter
-  API.  See doc/html/Filters.html for details.
-
-* Alpha-quality 2d ragged arrays are implemented as a layer built on
-  top of other hdf5 objects.  The API and storage format will almost
-  certainly change.
-
-* More debugging support including API tracing.  See Debugging.html.
-
-* C and Fortran style 8-bit fixed-length character string types are
-  supported with space or null padding or null termination and
-  translations between them.
-
-* Added function H5Fflush() to write all cached data immediately to
-  the file.
-
-* Datasets maintain a modification time which can be retrieved with
-  H5Gstat().
-
-* The h5ls tool can display much more information, including all the
-  values of a dataset.
-
-
-VI. Changes Since The First Alpha 1.0.0 Release
-
-* Two of the packages have been renamed.  The data space API has been
-  renamed from `H5P' to `H5S' and the property list (template) API has 
-  been renamed from `H5C' to `H5P'.
-
-* The new attribute API `H5A' has been added.  An attribute is a small 
-  dataset which can be attached to some other object (for instance, a
-  4x4 transformation matrix attached to a 3-dimensional dataset, or an 
-  English abstract attached to a group).
-
-* The error handling API `H5E' has been completed.  By default, when an
-  API function returns failure an error stack is displayed on the
-  standard error stream.  The H5Eset_auto() controls the automatic
-  printing and H5E_BEGIN_TRY/H5E_END_TRY macros can temporarily
-  disable the automatic error printing.
-
-* Support for large files and datasets (>2GB) has been added.  There
-  is an html document that describes how it works.  Some of the types
-  for function arguments have changed to support this: all arguments
-  pertaining to sizes of memory objects are `size_t' and all arguments 
-  pertaining to file sizes are `hsize_t'.
-
-* More data type conversions have been added although none of them are
-  fine tuned for performance.  There are new converters from integer
-  to integer and float to float, but not between integers and floating
-  points.  A bug has been fixed in the converter between compound
-  types.
-
-* The numbered types have been removed from the API: int8, uint8,
-  int16, uint16, int32, uint32, int64, uint64, float32, and float64.
-  Use standard C types instead.  Similarly, the numbered types were
-  removed from the H5T_NATIVE_* architecture; use unnumbered types
-  which correspond to the standard C types like H5T_NATIVE_INT.
-
-* More debugging support was added.  If tracing is enabled at
-  configuration time (the default) and the HDF5_TRACE environment
-  variable is set to a file descriptor then all API calls will emit
-  the function name, argument names and values, and return value on
-  that file number.  There is an html document that describes this.
-  If appropriate debugging options are enabled at configuration time,
-  some packages will display performance information on stderr.
-
-* Data types can be stored in the file as independent objects and
-  multiple datasets can share a data type.
-
-* The raw data I/O stream has been implemented and the application can 
-  control meta and raw data caches, so I/O performance should be
-  improved from the first alpha release.
-
-* Group and attribute query functions have been implemented so it is
-  now possible to find out the contents of a file with no prior
-  knowledge.
-
-* External raw data storage allows datasets to be written by other
-  applications or I/O libraries and described and accessed through
-  HDF5.
-
-* Hard and soft (symbolic) links are implemented which allow groups to 
-  share objects. Dangling and recursive symbolic links are supported.
-
-* User-defined data compression is implemented although we may
-  generalize the interface to allow arbitrary user-defined filters
-  which can be used for compression, checksums, encryption,
-  performance monitoring, etc.  The publicly-available `deflate'
-  method is predefined if the GNU libz.a can be found at configuration 
-  time.
-
-* The configuration scripts have been modified to make it easier to
-  build debugging vs. production versions of the library.
-
-* The library automatically checks that the application was compiled
-  with the correct version of header files.
-
-
-		    Parallel HDF5 Changes
-
-* Parallel support for fixed dimension datasets with contiguous or
-  chunked storages.  Also, support unlimited dimension datasets which
-  must use chunk storage.  No parallel support for compressed datasets.
-
-* Collective data transfer for H5Dread/H5Dwrite.  Collective access
-  support for datasets with contiguous storage only, thus only fixed
-  dimension datasets for now.
-
-* H5Pset_mpi and H5Pget_mpi no longer have the access_mode
-  argument.  It is taken over by the data-transfer property list
-  of H5Dread/H5Dwrite.
-
-* New functions H5Pset_xfer and H5Pget_xfer to handle the
-  specification of independent or collective data transfer_mode
-  in the dataset transfer properties list.  The properties
-  list can be used to specify data transfer mode in the H5Dwrite
-  and H5Dread function calls.
-
-* Added parallel support for datasets with chunked storage layout.
-  When a dataset is extend in a PHDF5 file, all processes that open
-  the file must collectively call H5Dextend with identical new dimension
-  sizes.
-

Release Information for hdf5-1.2.2 + +INTRODUCTION + +This document describes the differences between HDF5-1.2.1 and +HDF5-1.2.2, and contains information on the platforms where HDF5-1.2.2 +was tested and known problems in HDF5-1.2.2. + +The HDF5 documentation can be found on the NCSA ftp server +(ftp.ncsa.uiuc.edu) in the directory: + + /HDF/HDF5/docs/ + +For more information look at the HDF5 home page at: + + http://hdf.ncsa.uiuc.edu/HDF5/ + +If you have any questions or comments, please send them to: + + hdfhelp@ncsa.uiuc.edu + + +CONTENTS + +- Features Added since HDF5-1.2.1 +- Bug Fixes since HDF5-1.2.1 +- Known Problems +- Platforms Tested + + +Features Added since HDF5-1.2.1 +=============================== + * Added internal free-lists to reduce memory required by the library and + H5garbage_collect API function. + * h5dump displays opaque and bitfield types. + * New features added to snapshots. Use 'snapshot help' to see a + complete list of features. + * Improved configure to detect if MPIO routines are available when + parallel mode is requested. + +Bug Fixes since HDF5-1.2.1 +========================== + * h5dump correctly displays compound datatypes, including simple and + nested compound types. + * h5dump correctly displays the committed copy of predefined types. + * Corrected an error in h5toh4 which did not convert the 32-bit + int from HDF5 to HDF4 correctly for the T3E platform. + * Corrected a floating point number conversion error for the + Cray J90 platform. The error did not convert the value 0.0 + correctly. + * Fixed error in H5Giterate which was not updating the "index" parameter + correctly. + * Fixed error in hyperslab iteration which was not walking through the + correct sequence of array elements if hyperslabs were staggered in a + certain pattern. + * Fixed several other problems in hyperslab iteration code. + * Fixed another H5Giterate bug which caused groups with large numbers + of objects in them to misbehave when the callback function returned + non-zero values. + * Changed return type of H5Aiterate and H5A_operator_t typedef to be + herr_t, to align them with the dataset and group iterator functions. + * Changed H5Screate_simple and H5Sset_extent_simple to not allow dimensions + of size 0 without the same dimension being unlimited. + * Improved metadata hashing & caching algorithms to avoid + many hash flushes and also removed some redundant I/O when moving metadata + blocks in the file. + * The libhdf5.settings file shows the correct machine byte-sex. + * The "struct(opt)" type conversion function which gets invoked for + certain compound datatype conversions was fixed for nested compound + types. This required a small change in the datatype conversion + function API. + +Known Problems +============== + +o SunOS 5.6 with C WorkShop Compilers 4.2: hyperslab selections will + fail if library is compiled using optimization of any level. +o TFLOPS: dsets test fails if compiled with optimization turned on. +o J90: tools fail to dispay data for the datasets with a compound datatype. + +Platforms Tested +================ + + AIX 4.3.3 (IBM SP) 3.6.6 | binaries + mpicc using mpich 1.1.2 | are not + mpicc_r using IBM MPI-IO prototype | available + AIX 4.3.2.0 (IBM SP) xlc 5.0.1.0 + Cray J90 10.0.0.7 cc 6.3.0.2 + Cray T3E 2.0.5.29 cc 6.3.0.2 + mpt.1.3 + FreeBSD 4.0 gcc 2.95.2 + HP-UX B.10.20 HP C HP92453-01 A.10.32 + HP-UX B.11.00 HP92453-01 A.11.00.13 HP C Compiler + (static library only, h5toh4 tool is not available) + IRIX 6.5 MIPSpro cc 7.30 + IRIX64 6.5 (64 & n32) MIPSpro cc 7.3.1m + mpt.1.4 + + Linux 2.2.10 SMP gcc 2.95.1 + mpicc(gcc-2.95.1) + gcc (egcs-2.91.66) + mpicc (egcs-2.91.66) + Linux 2.2.16 (RedHat 6.2) gcc 2.95.2 + + OSF1 V4.0 DEC-V5.2-040 + SunOS 5.6 cc WorkShop Compilers 5.0 no optimization + SunOS 5.7 cc WorkShop Compilers 5.0 + SolarisX86 SunOS 5.5.1 gcc version 2.7.2 with --disable-hsizet + TFLOPS 3.2.1 pgcc Rel 3.1-3i + mpich-1.1.2 with local changes + Windows NT4.0 sp5 MSVC++ 6.0 + Windows 98 MSVC++ 6.0 + Windows 2000 MSVC++ 6.0 + + + +%%%%1.2.1%%%% Release Information for hdf5-1.2.1 + +II. Release Information for hdf5-1.2.1 + +Bug fixes since HDF5-1.2.0 +========================== + +Configuration +------------- + + * The hdf5.h include file was fixed to allow the HDF5 Library to be compiled + with other libraries/applications that use GNU autoconf. + * Configuration for parallel HDF5 was improved.

Changes Since Version 1.0.1 + --------------------------- + +1. Documentation + ------------- + +* More examples + +* Updated user guide, reference manual, and format specification. + +* Self-contained documentation for installations isolated from the + Internet. + +* HDF5 Tutorial was added to the documentation + +2. Configuration + ------------- + +* Better detection and support for MPI-IO. + +* Recognition of compilers with known code generation problems. + +* Support for various compilers on a single architecture (e.g., the + native compiler and the GNU compilers). + +* Ability to build from read-only media and with different compilers + and/or options concurrently. + +* Added a libhdf5.settings file which summarizes the configuration + information and is installed along with the library. + +* Builds a shared library on most systems that support it. + +* Support for Cray T3E, J90 and Windows/NT. + +3. Debugging + --------- + +* Improved control and redirection of debugging and tracing messages. + +4. Datatypes + --------- + +* Optimizations to compound datatype conversions and I/O operations. + +* Added nearly 100 optimized conversion functions for native datatypes + including support for non-aligned data. + +* Added support for bitfield, opaque, and enumeration types. + +* Added distinctions between signed and unsigned char types to the + list of predefined native hdf5 datatypes. + +* Added HDF5 type definitions for C9x types like int32_t. + +* Application-defined type conversion functions can handle non-packed + data. + +* Changed the H5Tunregister() function to use wildcards when matching + conversion functions. H5Tregister_hard() and H5Tregister_soft() + were combined into H5Tregister(). + +* Support for variable-length datatypes (arrays of varying length per + dataset element). Variable length strings currently supported only + as variable length arrays of 1-byte integers. + +5. Dataspaces + ---------- + +* New query functions for selections. + +* I/O operations bypass the stripmining loop and go directly to + storage for certain contiguous selections in the absense of type + conversions. In other cases the stripmining buffers are used more + effectively. + +* Reduced the number of I/O requests under certain circumstances, + improving performance on systems with high I/O latency. + +6. Persistent Pointers + ------------------- + +* Object (serial and parallel) and dataset region (serial only) + references are implemented. + +7.

Changes from Release 1.0.0 to Release 1.0.1 + +* [Improvement]: configure sets up the Makefile in the parallel tests + suit (testpar/) correctly. + +* [Bug-Fix]: Configure failed for all IRIX versions other than 6.3. + It now configures correctly for all IRIX 6.x version. + +* Released Parallel HDF5 + + Supported Features: + ------------------ + + HDF5 files are accessed according to the communicator and INFO + object defined in the property list set by H5Pset_mpi. + + Independent read and write accesses to fixed and extendable dimension + datasets. + + Collective read and write accesses to fixed dimension datasets. + + Supported Platforms: + ------------------- + + Intel Red + IBM SP2 + SGI Origin 2000 + + Changes In This Release: + ----------------------- + + o Support of Access to Extendable Dimension Datasets. + Extendable dimension datasets must use chunked storage methods. + A new function, H5Dextend, is created to extend the current + dimensions of a dataset. The current release requires the + MPI application must make a collective call to extend the + dimensions of an extendable dataset before writing to the + newly extended area. (The serial does not require the + call of H5Dextend. The dimensions of an extendable + dataset is increased when data is written to beyond the + current dimensions but within the maximum dimensions.) + The required collective call of H5Dextend may be relaxed + in future release. + + This release only support independent read and write accesses + to extendable datasets. Collective accesses to extendable + datasets will be implemented in future releases. + + o Collective access to fixed dimension datasets. + Collective access to a dataset can be specified in the transfer + property list argument in H5Dread and H5Dwrite. The current + release supports collective access to fixed dimension datasets. + Collective access to extendable datasets will be implemented in + future releases. + + o HDF5 files are opened according to Communicator and INFO object. + H5Dopen now records the communicator and INFO setup by H5Pset_mmpi + and pass them to the corresponding MPIO open file calls for + processing. + + o This release has been tested on IBM SP2, Intel Red and SGI Origin 2000 + systems. It uses the ROMIO version of MPIO interface for parallel + I/O supports. + + + +%%%%1.0.0%%%% Release Information for hdf5-1.0.0 + +V. Changes from the Beta 1.0.0 Release to Release 1.0.0 + +* Added fill values for datasets. For contiguous datasets fill value + performance may be quite poor since the fill value is written to the + entire dataset when the dataset is created. This will be remedied + in a future version. Chunked datasets using fill values do not + incur any additional overhead. See H5Pset_fill_value(). + +* Multiple hdf5 files can be "mounted" on one another to create a + larger virtual file. See H5Fmount(). + +* Object names can be removed or changed but objects are never + actually removed from the file yet. See H5Gunlink() and H5Gmove(). + +* Added a tuning mechanism for B-trees to insure that sequential + writes to chunked datasets use less overhead. See H5Pset_btree_ratios(). + +* Various optimizations and bug fixes. + + + +%%%%1.0.0 Beta%%%% Release Information for hdf5-1.0.0 Beta + +VI. Changes from the Second Alpha 1.0.0 Release to the Beta 1.0.0 Release + +* Strided hyperslab selections in dataspaces now working. + +* The compression API has been replaced with a more general filter + API. See doc/html/Filters.html for details. + +* Alpha-quality 2d ragged arrays are implemented as a layer built on + top of other hdf5 objects. The API and storage format will almost + certainly change. + +* More debugging support including API tracing. See Debugging.html. + +* C and Fortran style 8-bit fixed-length character string types are + supported with space or null padding or null termination and + translations between them. + +* Added function H5Fflush() to write all cached data immediately to + the file. + +* Datasets maintain a modification time which can be retrieved with + H5Gstat(). + +* The h5ls tool can display much more information, including all the + values of a dataset. + + + +%%%%1.0.0 Alpha 2%%%% Release Information for hdf5-1.0.0 Alpha 2 + +VII. Changes from the First Alpha 1.0.0 Release to + the Second Alpha 1.0.0 Release + +* Two of the packages have been renamed. The data space API has been + renamed from `H5P' to `H5S' and the property list (template) API has + been renamed from `H5C' to `H5P'. + +* The new attribute API `H5A' has been added. An attribute is a small + dataset which can be attached to some other object (for instance, a + 4x4 transformation matrix attached to a 3-dimensional dataset, or an + English abstract attached to a group). + +* The error handling API `H5E' has been completed. By default, when an + API function returns failure an error stack is displayed on the + standard error stream. The H5Eset_auto() controls the automatic + printing and H5E_BEGIN_TRY/H5E_END_TRY macros can temporarily + disable the automatic error printing. + +* Support for large files and datasets (>2GB) has been added. There + is an html document that describes how it works. Some of the types + for function arguments have changed to support this: all arguments + pertaining to sizes of memory objects are `size_t' and all arguments + pertaining to file sizes are `hsize_t'. + +* More data type conversions have been added although none of them are + fine tuned for performance. There are new converters from integer + to integer and float to float, but not between integers and floating + points. A bug has been fixed in the converter between compound + types. + +* The numbered types have been removed from the API: int8, uint8, + int16, uint16, int32, uint32, int64, uint64, float32, and float64. + Use standard C types instead. Similarly, the numbered types were + removed from the H5T_NATIVE_* architecture; use unnumbered types + which correspond to the standard C types like H5T_NATIVE_INT. + +* More debugging support was added. If tracing is enabled at + configuration time (the default) and the HDF5_TRACE environment + variable is set to a file descriptor then all API calls will emit + the function name, argument names and values, and return value on + that file number. There is an html document that describes this. + If appropriate debugging options are enabled at configuration time, + some packages will display performance information on stderr. + +* Data types can be stored in the file as independent objects and + multiple datasets can share a data type. + +* The raw data I/O stream has been implemented and the application can + control meta and raw data caches, so I/O performance should be + improved from the first alpha release. + +* Group and attribute query functions have been implemented so it is + now possible to find out the contents of a file with no prior + knowledge. + +* External raw data storage allows datasets to be written by other + applications or I/O libraries and described and accessed through + HDF5. + +* Hard and soft (symbolic) links are implemented which allow groups to + share objects. Dangling and recursive symbolic links are supported. + +* User-defined data compression is implemented although we may + generalize the interface to allow arbitrary user-defined filters + which can be used for compression, checksums, encryption, + performance monitoring, etc. The publicly-available `deflate' + method is predefined if the GNU libz.a can be found at configuration + time. + +* The configuration scripts have been modified to make it easier to + build debugging vs. production versions of the library. + +* The library automatically checks that the application was compiled + with the correct version of header files. + + + Parallel HDF5 Changes + +* Parallel support for fixed dimension datasets with contiguous or + chunked storages. Also, support unlimited dimension datasets which + must use chunk storage. No parallel support for compressed datasets. + +* Collective data transfer for H5Dread/H5Dwrite. Collective access + support for datasets with contiguous storage only, thus only fixed + dimension datasets for now. + +* H5Pset_mpi and H5Pget_mpi no longer have the access_mode + argument. It is taken over by the data-transfer property list + of H5Dread/H5Dwrite. + +* New functions H5Pset_xfer and H5Pget_xfer to handle the + specification of independent or collective data transfer_mode + in the dataset transfer properties list. The properties + list can be used to specify data transfer mode in the H5Dwrite + and H5Dread function calls. + +* Added parallel support for datasets with chunked storage layout. + When a dataset is extend in a PHDF5 file, all processes that open + the file must collectively call H5Dextend with identical new dimension + sizes. + + + LIST OF API FUNCTIONS + +The following functions are implemented. Errors are returned if an +attempt is made to use some feature which is not implemented and +printing the error stack will show `not implemented yet'. + +Library + H5check - check that lib version matches header version + H5open -

It also provides an API for user defined file drivers. + * New features added to snapshots. Use 'snapshot help' to see a + complete list of features. + * Improved configure to detect if MPIO routines are available when + parallel mode is requested. + * Added Thread-Safe support. Phase I implemented. + * Added data sieve buffering to raw data I/O path. This is enabled + for all VFL drivers except the mpio & core drivers. Setting the + sieve buffer size is controlled with the new API function, + H5Pset_sieve_buf_size(), and retrieved with H5Pget_sieve_buf_size(). + * Added new Virtual File Driver, Stream VFD, to send/receive entire + HDF5 files via socket connections. + * As parts of VFL, HDF-GASS and HDF-SRB are also added to this + release. To find out details, please read INSTALL_VFL file. + * Increased maximum number of dimensions for a dataset (H5S_MAX_RANK) + from 31 to 32 to align with HDF4 & netCDF. + * Added 'query' function to VFL drivers. Also added 'type' parameter to + VFL 'read' & 'write' calls, so they are aware of the type of data + being accessed in the file. Updated the VFL document also. + * A new h4toh5 uitlity, to convert HDF4 files to analogous HDF5 files. + * Added a new array datatype to the datatypes which can be created. Removed + "array fields" from compound datatypes (use an array datatype instead). + * Parallel HDF5 works correctly with mpich-1.2.1 on Solaris, SGI, Linux. + +h4toh5 Utility +============== + + The h4toh5 utility is a new utility that converts an HDF4 file to an + HDF5 file. For details, see the document, "Mapping HDF4 Objects to + HDF5 Objects": + http://hdf.ncsa.uiuc.edu/HDF5/papers/H4-H5MappingGuidelines.pdf + + Known Limitations of the h4toh5 beta release + --------------------------------------------- + + 1. Error Handling + + Error reporting is minimal. + + 2. String Datatype + + HDF4 has no 'string' type. String valued data are usually defined as + an array of 'char' in HDF4. The h4toh5 utility will generally map + these to HDF5 'String' types rather than array of char, with the + following additional rules: + + * For the data of an HDF4 SDS, image, and palette, if the data is + declared 'DFNT_CHAR8' it will be assumed to be integer and + will be an H5T_INTEGER type. + * For attributes of any HDF4 object, data of type 'DFNT_CHAR8' + will be converted to an HDF5 'H5T_STRING' type. + * For an HDF4 Vdata, it is difficult to determine whether data + of type 'DFNT_CHAR8' is intended to be bytes or characters. + The h4toh5 utility will consider them to be C characters, and + will convert them to an HDF5 'H5T_STRING' type. + + + 3. Compression, Chunking and External Storage + + Chunking is supported, but compression and external storage is not. + + An HDF4 object that uses chunking will be converted to an HDF5 file + with analogous chunked storage. + + An HDF4 object that uses compression will be converted to an + uncompressed HDF5 object. + + An HDF4 object that uses external storage will be converted to an + HDF5 object without external storage. + + 4. Memory Use + + The beta version of the h4toh5 utility copies data from HDF4 objects + in a single read followed by a single write to the HDF5 object. For + large objects, this requires a very large amount of memory, which may + be extremely slow or fail on some platforms. + + Note that a dataset that has only been partly written will + be read completely, including uninitialized data, and all the + data will be written to the HDF5 object. + + 5. Platforms + + The h4toh5 utility requires HDF5.1.4 and HDF4r1.4 + + The beta h4toh5 utility has been tested on Solaris 2.6, Solaris 2.5, + Irix 6.5, HPUX 11.0, DEC Unix, FreeBSD, Windows 2000(NT5.0),Windows NT + and Windows 98. + +F90 Support +=========== + + This is the first release of the HDF5 Library with fully integrated + F90 API support. The Fortran Library is created when the + --enable-fortran flag is specified during configuration. + + Not all F90 subroutines are implemented. Please refer to the HDF5 + Reference Manual for more details. + + F90 APIs are available for the Solaris 2.6 and 2.7, Linux, DEC UNIX, + T3E, J90 and O2K (64 bit option only) platforms. The Parallel version of + the HDF5 F90 Library is supported on the O2K and T3E platforms. + + Changes since the last prototype release (July 2000) + ---------------------------------------------------- + + * h5open_f and h5close_f must be called instead of h5init_types and + h5close_types. + + * The following subroutines are no longer available: + h5pset_xfer_f + h5pget_xfer_f + h5pset_mpi_f + h5pget_mpi_f + h5pset_stdio_f + h5pget_stdio_f + h5pset_sec2_f + h5pget_sec2_f + h5pset_core_f + h5pget_core_f + h5pset_family_f + h5pget_family_f + + * The following functions have been added: + h5pset_fapl_mpio_f + h5pget_fapl_mpio_f + h5pset_dxpl_mpio_f + h5pget_dxpl_mpio_f + + * In the previous HDF5 F90 releases, the implementation of object + references and dataset region references was not portable. This + release introduces a portable implementation, but it also introduces + changes to the read/write APIs that handle references. If object or + dataset region references are written or read to/from an HDF5 file, + h5dwrite_f and h5dread_f must use the extra parameter, n, for the + buffer size: + + h5dwrite(read)_f(dset_id, mem_type_id, buf, n, hdferr, & + ^^^ + mem_space_id, file_space_id, xfer_prp) + + For other datatypes the APIs were not changed. + + +C++ Support +=========== + + This is the first release of the HDF5 Library with fully integrated + C++ API support. The HDF5 C++ library is built when the --enable-cxx + flag is specified during configuration. + + Check the HDF5 Reference Manual for available C++ documentation. + + C++ APIs are available for Solaris 2.6 and 2.7, Linux, and FreeBSD. + + +Bug Fixes since HDF5-1.2.0 +========================== + +Library +------- + + * The function H5Pset_mpi is renamed as H5Pset_fapl_mpio. + * Corrected a floating point number conversion error for the Cray J90 + platform. The error did not convert the value 0.0 correctly. + * Error was fixed which was not allowing dataset region references to + have their regions retrieved correctly. + * Corrected a bug that caused non-parallel file drivers to fail in + the parallel version. + * Added internal free-lists to reduce memory required by the library + and H5garbage_collect API function + * Fixed error in H5Giterate which was not updating the "index" + parameter correctly. + * Fixed error in hyperslab iteration which was not walking through the + correct sequence of array elements if hyperslabs were staggered in a + certain pattern + * Fixed several other problems in hyperslab iteration code. + * Fixed another H5Giterate bug which was causes groups with large + numbers of objects in them to misbehave when the callback function + returned non-zero values. + * Changed return type of H5Aiterate and H5A_operator_t typedef to be + herr_t, to align them with the dataset and group iterator functions. + * Changed H5Screate_simple and H5Sset_extent_simple to not allow + dimensions of size 0 with out the same dimension being unlimited. + * QAK - 4/19/00 - Improved metadata hashing & caching algorithms to + avoid many hash flushes and also remove some redundant I/O when + moving metadata blocks in the file. + * The "struct(opt)" type conversion function which gets invoked for + certain compound datatype conversions was fixed for nested compound + types. This required a small change in the datatype conversion + function API. + * Re-wrote lots of the hyperslab code to speed it up quite a bit. + * Added bounded garbage collection for the free lists when they run + out of memory and also added H5set_free_list_limits API call to + allow users to put an upper limit on the amount of memory used for + free lists. + * Checked for non-existent or deleted objects when dereferencing one + with object or region references and disallow dereference. + * "Time" datatypes (H5T_UNIX_D*) were not being stored and retrieved + from object headers correctly, fixed now. + * Fixed H5Dread or H5Dwrite calls with H5FD_MPIO_COLLECTIVE requests + that may hang because not all processes are transfer the same amount + of data. (A.K.A. prematured collective return when zero amount data + requested.) Collective calls that may cause hanging is done via the + corresponding MPI-IO independent calls. + * If configure with --enable-debug=all, couple functions would issue + warning messages to "stderr" that the operation is expensive time-wise. + This messed up applications (like testings) that did not expect the + extra output. It is changed so that the warning will be printed only + if the corresponding Debug key is set. + +Configuration +------------- + + * The hdf5.h include file was fixed to allow the HDF5 Library to be + compiled with other libraries/applications that use GNU autoconf. + * Configuration for parallel HDF5 was improved. Configure now attempts + to link with libmpi.a and/or libmpio.a as the MPI libraries by + default. It also uses "mpirun" to launch MPI tests by default. It + tests to link MPIO routines during the configuration stage, rather + than failing later as before. One can just do "./configure + --enable-parallel" if the MPI library is in the system library. + * Added support for pthread library and thread-safe option. + * The libhdf5.settings file shows the correct machine byte-sex. + * Added option "--enable-stream-vfd" to configure w/o the Stream VFD. + For Solaris, added -lsocket to the LIBS list of libraries. + +Tools +----- + * h5dump now accepts both short and long command-line parameters: + -h, --help Print a usage message and exit + -B, --bootblock Print the content of the boot block + -H, --header Print the header only; no data is displayed + -i, --object-ids Print the object ids + -V, --version Print version number and exit + -a P, --attribute=P Print the specified attribute + -d P, --dataset=P Print the specified dataset + -g P, --group=P Print the specified group and all members + -l P, --soft-link=P Print the value(s) of the specified soft link + -o F, --output=F Output raw data into file F + -t T, --datatype=T Print the specified named data type + -w #, --width=# Set the number of columns + + P - is the full path from the root group to the object. + T - is the name of the data type. + F - is a filename. + # - is an integer greater than 1. + * A change from the old way command line parameters were interpreted + is that multiple attributes, datasets, groups, soft-links, and + object-ids cannot be specified with just one flag but you have to + use a flag with each object. I.e., instead of doing this: + + h5dump -a /attr1 /attr2 foo.h5 + + do this: + + h5dump -a /attr1 -a /attr2 foo.h5 + + The cases are similar for the other object types. + * h5dump correctly displays compound datatypes. + * Corrected an error in h5toh4 which did not convert the 32bits + int from HDF5 to HDF4 corectly for the T3E platform. + * h5dump correctly displays the committed copy of predefined types + correctly. + * Added an option, -V, to show the version information of h5dump. + * Fixed a core dumping bug of h5toh4 when executed on platforms like + TFLOPS. + * The test script for h5toh4 used to not able to detect the hdp + dumper command was not valid. It now detects and reports the + failure of hdp execution. + * Merged the tools with the 1.2.2 branch. Required adding new + macros, VERSION12 and VERSION13, used in conditional compilation. + Updated the Windows project files for the tools. + * h5dump displays opaque and bitfield data correctly. + * h5dump and h5ls can browse files created with the Stream VFD + (eg. "h5ls :"). + * h5dump has a new feature "-o " which outputs the raw data + of the dataset into ascii text file . + * h5toh4 used to converts hdf5 strings type to hdf4 DFNT_INT8 type. + Corrected to produce hdf4 DFNT_CHAR type instead. + * h5dump and h5ls displays array data correctly. + +Documentation +------------- + + * User's Guide and Reference Manual were updated. + See doc/html/PSandPDF/index.html for more details. + + +Bug Fixes since HDF5-1.4.0-beta2 +================================ + + * Corrected configuration error which was not including compression support + correctly. + * Cleaned up lots of warnings. + * Changed a few h5dump command line switches and added long versions of + the switches. + * Changed parameters for H5Tconvert, H5Pset_bufer and H5Pget_buffer from + size_t to hsize_t + * Fixed fairly obscure bug in hyperslab I/O which could (in rare cases) + not copy all the data during a transfer. + * Removed ragged array code from library. + * F90 library and module files are installed properly now on all supported platforms. + +Platforms Tested +================ + + Note: Due to the nature of the bug fixes, only static versions of the + library and tools were tested. + + + AIX 4.3.2 (IBM SP) mpcc_r 3.6.6 + Cray T3E sn6711 2.0.5.43 Cray Standard C Version 6.4.0.0 + Cray Fortran Version 3.4.0.2 + FreeBSD 4.2 gcc 2.95.2 + g++ 2.95.2 + HP-UX B.10.20 HP C HP92453-01 A.10.32.30 + HP-UX B.11.00 HP C HP92453-01 A.11.00.13 + IRIX 6.5 MIPSpro cc 7.30 + IRIX64 6.5 (64 & n32) MIPSpro cc 7.3.1m + mpt.1.4.0.2 + mpich-1.2.1 + Linux 2.2.16-3smp gcc-2.95.2 + g++ 2.95.2 + pgf90 3.1-3 + OSF1 V4.0 DEC-V5.2-040 + Digital Fortran 90 V4.1-270 + SunOS 5.6 WorkShop Compilers 5.0 98/12/15 C 5.0 + (Solaris 2.6) WorkShop Compilers 5.0 99/10/25 Fortran 90 + 2.0 Patch 107356-04 + Workshop Compilers 5.0 98/12/15 C++ 5.0 + SunOS 5.7 WorkShop Compilers 5.0 98/12/15 C 5.0 + (Solaris 2.7) WorkShop Compilers 5.0 99/10/25 Fortran 90 + 2.0 Patch 107356-04 + Workshop Compilers 5.0 98/12/15 C++ 5.0 + TFLOPS 3.3 mpich-1.2.0 with local changes + Windows NT4.0, 2000 (NT5.0) MSVC++ 6.0 + Windows 98 MSVC++ 6.0 + +Known Problems +============== + +* 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 Linux platforms using the gcc-2.95.2 compiler. + + 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 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: + - Solaris x86 2.5.1, Cray T3E and Cray J90 give errors during testing + when displaying object references in certain files. These are benign + differences due to the difference in sizes of the objects created on + those platforms. h5ls appears to be dumping object references + correctly. + - Cray J90 (and Cray T3E?) 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 (T3E and J90) + 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 the + ftp://hdf.ncsa.uiuc.edu/pub/ougoing/hdf5/hdf5-1.4.0-beta/F90_source_for_Crays + directory. -- cgit v0.12
