* [svn-r5841] Snapshot version 1.5 release 32HDF Admin2002-08-0311-49/+59
|
* [svn-r5840] Purpose:Quincey Koziol2002-07-3120-790/+556
| | | | | | | | | | | | | | Code cleanup Description: Created a new H5I function which combined the some of the functionality of H5I_get_type and H5I_object: H5I_object_verify. Using this new function in the library trims another ~200 lines of code off the library and makes the resulting binaries smaller and faster also. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5839] Purpose:Quincey Koziol2002-07-3116-1962/+1829
| | | | | | | | | | | | | | | Code cleanup Description: Move operations on each type of selection into the source code file for each selection type (all->H5Sall.c, hyperslab->H5Shyper.c, etc.) Remove central H5S_select_<foo> operations, instead calling the operations through function pointers in each selection (a much more object-oriented approach). Platforms tested: FreeBSD 4.6 (sleipnir)

| | | | | | | | | | | Purpose: update windows support. Description: 1. Since we don't support w98 anymore, delete the description about w98. Actually DLL may work on w98. 2. Release dll work for new HDF5 release. Solution: Platforms tested:

| | | | | | | | | | | | | | | Purpose: move zlib out of hdf5/src from development branch update H5pubconf.h Description: The decision has been made to move zlib out of hdf5 source distribution, make it real in development branch. In dev. branch, H5_HAVE_COMPRESSION replaces H5_HAVE_COMPRESS2, H5_HAVE_ZLIB_H and H5_HAVE_LIBZ etc. Make windows consistent. Solution: Platforms tested: windows 2000

* [svn-r5834] Purpose:Quincey Koziol2002-07-249-6141/+2735
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Large code cleanup/re-write Description: This is phase 1 of the data I/O re-architecture, with the following changes: - Changed the selection drivers to not actually do any I/O, they only generate the sequences of offset/length pairs needed for the I/O (or memory access, in the case of iterating or filling a selection in a memory buffer) - Wrote more abstract I/O routines which get the sequence of offset/ length pairs for each selection and access perform the I/O or memory access. Benefits of this change include: - Removed ~3400 lines of quite redundant code, with corresponding reduction in the size of library binary. - Any selection can now directly access memory when performing I/O, if no type conversions are required, instead of just "regular" hyperslab and 'all' selections, which speeds up I/O. - Sped up I/O for hyperslab selections which have contiguous lower dimensions by "flattening" them out into lesser dimensional objects for the I/O. No file format or API changes were necessary for this change. The next phase will be to create a "selection driver" for each type of selection, allowing each type of selection to directly call certain methods that only apply to that type of selection, instead of passing through dozens of functions which have switch statements to call the appropriate method for each selection type. This will also reduce the amount of code in the library and speed things up a bit more. Phase 3 will involve generating an MPI datatype for all types of selections, instead of only "regular" hyperslab and 'all' selections. This will allow collective parallel I/O for all I/O operations which don't require type conversions. It will also open up the door for allowing collective I/O on datasets which require type conversion. Phase 4 will involve changing the access pattern to deal with chunked datasets in a more optimal way (in serial). Phase 5 will deal with accessing chunked datasets more optimally for collective parallel I/O operations. Platforms tested: FreeBSD 4.6 (sleipnir) w/ parallel & C++ and IRIX64 6.5 (modi4) w/parallel

* [svn-r5819] Purpose:Quincey Koziol2002-07-211-6/+2
| | | | | | | | | | | | | | Bug Fix Description: non-parallel case for new metadata cache flushing property wasn't set up correctly. Solution: Initialize variables correctly. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5815] Purpose:Quincey Koziol2002-07-191-2/+2
| | | | | | | | | | | | | | | | | Bug fix Description: t_mpi test program was not being run with the RUNPARALLEL command Solution: Put the t_mpi program into the TEST_PROGS_PARA macro instead of the TEST_PROGS macro Hopefully this'll fix the daily test problems on arabica, but I can't test it because I can't get mpirun to work correctly for me. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5814] Purpose:Quincey Koziol2002-07-1912-112/+310
| | | | | | | | | | | | | | | | | | Bug Fix Description: It was possible to create corrupted metadata information (either in memory or in the file or both) with a parallel I/O program because of the way metadata writes were being handled for writes out of the metadata cache. Solution: Added a dataset transfer property called "block before metadata write" which is used by the MPI-I/O and MPI-posix drivers to sync up all the processes before attempting a metadata write. This property is currently only for metadata writes from the metadata cache. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5812] Raymond Lu2002-07-173-21/+234
| | | | | | | | | Purpose: Bug fix. Description: This should fix the nested VL datatype bug. Platforms tested: modi4, eirene, impact
* [svn-r5810] Purpose:Bill Wendling2002-07-172-2/+2
| | | | | | | | | | | Fix Description: Better check for versions of Linux. We didn't support kernels with major version numbers >2 and minor version numbers <4... Solution: Fixed to check just that. Platforms tested: Linux 2.2 && 2.4
* [svn-r5809] Purpose:Quincey Koziol2002-07-171-1/+1
| | | | | | | | | | | | | | Bug fix Description: Deleting objects from a global heap was incorrectly setting the free space in the heap chunk. Solution: Encode correct amount of free space. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5807] Purpose:Bill Wendling2002-07-178-417/+825
| | | | | | | | | | | | | | | | | | | | | | | | | Update, Bug Fix, and Feature Add Description: - Updated how AC_{ENABLE,WITH} help messages were being generated. Autoconf now gives you an AC_HELP_STRING macro to use to create them. - Fixed the problem with Linux LFS on RedHat 7.3 machines. It wasn't finding getdents64(), so we can't rely on that being present anymore... - Added GPFS detection and setting. - Updated how compression is specified. It's no longer necessary to test for HAVE_ZLIB_H, HAVE_LIBZ, and HAVE_COMPRESS2. The one macro {H5_}HAVE_COMPRESSION takes care of all of these. Solution: Changed the check for Linux LFS from looking for getdents() to looking at the version number of the kernel (using the uname -r command). You can still override with the --enable-linux-lfs switch if you really believe that your <2.4 kernel has LFS support. Platforms tested: Linux (2.2 and 2.4)
* [svn-r5805] Raymond Lu2002-07-151-3/+3

| | | | | | | | | | | | New feature. Description: Added MPI-posix VFL driver. This driver uses MPI to coordinate actions, but performs I/O directly with posix sec(2) I/O functions.

* [svn-r5795] Purpose:Quincey Koziol2002-07-154-5/+69
| | | | | | | | | | | New feature Description: Changed parallel I/O tests to use test script instead of just running testphdf5 executable. This allows the MPI-posix driver to be tested easily. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel and IRIX64 6.5 (modi4) w/parallel
* [svn-r5793] Purpose:Quincey Koziol2002-07-152-19/+37

* [svn-r5784] Purpose:Quincey Koziol2002-07-121-91/+100
| | | | | | | | | | | | | | | Bug fix. Description: "strong" file closing feature was re-using free'd memory for objects which were still open in the file. Solution: Used the "dmalloc" tools to determine where the memory was being re-used and re-arranged the code to avoid these cases. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5783] Purpose:Quincey Koziol2002-07-122-2/+6
| | | | | | | | | | New code Description: Add a few new error messages. Platforms tested: FreeBSD 4.6 (sleipnir)

* [svn-r5772] Frank Baker2002-07-051-3/+14
| | | | | | | | | | | | | | | Purpose: Add copyright and change "HDF5 Tutorial" link. Description: Added copyright statement and link. Changed the "Tutorial" link to point to the copy on the HDF5 website. Since the Tutorial is not maintained in CVS, the distributed version of the Tutorial is being unlinked and removed from the set of distributed files. It is hoped that we can begin maintaining the Tutorial under CVS prior to Release 1.6 and resume its distribution. Platforms tested: IE 5
* [svn-r5771] Frank Baker2002-07-051-1/+2

* [svn-r5769] Frank Baker2002-07-051-19/+20
| | | | | | | | | | | | Purpose: Bugfix Description: Corrected H5Zregister description, syntax, and parameter descriptions. There is one 'function' parameter, rather than the separate 'compression-function' and 'uncompression-function' parameters that were previously listed. Platforms tested: IE 5
