* [svn-r6178] ./hdf5-devel/src/H5Epublic.hRobb Matzke2002-12-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: New Feature; Optimization; Clean-up (Merged from 1.4 branch) Description: There is no symbolic constant to pass to functions that take an optional object ID for when the caller wants to indicate no object ID. In the past the caller always passed a negative integer. GPFS performs poorly. The h5ls tool decides whether to list the file name in the output based on a compile-time choice, which isn't always optimal at run time. Solution: Added a symbolic constant H5I_INVALID_HID. Added code to tell the mmfsd of GPFS to forego byte range token prefetching. h5ls decides whether to print the file name at runtime based on the number of objects being listed. Platforms tested: SuSE Linux (arborea), gcc and mpich-1.2.4 SunOS (baldric), gcc 2002-12-03 22:51:43 Robb Matzke <matzke@arborea.spizella.com> *: Added H5E_FCNTL minor error number.

Other changes are probably due to additional API tracing statements inserted automatically.
* [svn-r6172] Purpose:Quincey Koziol2002-12-041-1/+3
| | | | | | | Bug fix Description: Correct another missing field I overlooked earlier.
* [svn-r6170] Purpose:Quincey Koziol2002-12-041-0/+1

* [svn-r6149] ./hdf5-devel/src/H5Ipublic.hRobb Matzke2002-12-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Feature; Optimization Description: Clients pass `-1' or make their own #define for HDF5 functions that take an optional object ID. Blue's GPFS is slow for typical SAF restart dumps. Solution: Added a #define for H5I_INVALID_HID Added GPFS-specific code to H5FDmpiposix.c that tells mmfsd to forego byte range token prefetching. This code can be compiled into the library by defining USE_GPFS_HINTS. The plan is to either generalize this so it's detected during configure and turned on/off at runtime, or to move it up into DSL/SAF with the new HDF5 functions to that return the low-level file handle. Platforms tested: SuSE Linux (arborea), gcc and mpich-1.2.4 SunOS (baldric), gcc 2002-09-05 12:24:28 Robb Matzke <matzke@arborea.spizella.com> *: Added #define for H5I_INVALID_HID. An invalid object handle is actually any integer that isn't currently in use as a handle, and non-positive integers are never used as a handle. The #define is -1, and is mostly so that HDF5 users can pass a symbolic name instead of a negative number to functions that take optional object ID arguments.

| | | | | | | | | | | | | Code cleanup Description: Finish checkin of H5A API cleanups with header files I forgot on the first checkin pass. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir)
* [svn-r6114] Purpose:Quincey Koziol2002-11-206-115/+253
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Code Cleanup & New Feature Description: H5config.h.in: Removed H5_HAVE_COMPRESSION & H5_HAVE_FILTER_GZIP flags. Added H5_HAVE_FILTER_DEFLATE flag. H5Z.c: H5Zprivate.h: H5Zpublic.h: Switched from using H5_HAVE_COMPRESSION flag in favor of H5_HAVE_FILTER_DEFLATE. Added H5Zunregister & H5Zfilter_avail API functions. Changed a numeric constant (256) to a symbolic constant (H5Z_FILTER_RESERVED). Automatically add the shuffling filter to the list of available filters (when it is enabled). Moved prototypes for H5Z_filter_deflate & H5Z_filter_shuffle from the public header into the private header. H5Zdeflate.c: Switched from using H5_HAVE_COMPRESSION & H5_HAVE_FILTER_GZIP flags in favor of H5_HAVE_FILTER_DEFLATE. Cleaned up formatting & error reporting a bit. H5Zshuffle.c: Rewrote shuffling algorithm to be more efficient. Added error checking & reporting. Added standard Pablo information. Added standard function header comment. Added FUNC_ENTER & FUNC_LEAVE macros. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir)
* [svn-r6108] Purpose:Quincey Koziol2002-11-204-22/+14
| | | | | | | | | | | | Code cleanup. Description: Cleaned up compiler warnings & updated a few comments. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir)
* [svn-r6106] Purpose:Quincey Koziol2002-11-202-88/+78
| | | | | | | | | | | | | | | | | | | | | | | | | Code cleanup, Feature enhancement Description: Improve hashing algorithm to not generate as many clashes. Avoid using H5MD_realloc when changing the size of a chunk on disk. Instead, use H5MF_free followed by H5MF_alloc, which avoids copying the information from the space for the previous chunk to the space for the new chunk, since we are going to overwrite the chunk with new data anyway. This change should both improve I/O performance in situations where compressed chunks are being overwritten as well as reduce the space used in the file during that situation. Cleaned up error handling in a few cases. Removed old debugging printf()s. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir)
* [svn-r6104] Purpose:Quincey Koziol2002-11-201-0/+1
| | | | | | | | | | | | | | | | | Bug Fix Description: Free blocks of space in the file which were merged with a block before them were not updating the free list information correctly, allowing space in the file to over-allocated and potentially corrupted. Solution: Correct address of free block during merging. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir)
* [svn-r6088] MuQun Yang2002-11-131-1/+1

* [svn-r6087] MuQun Yang2002-11-134-0/+141
| | | | | | | | | | | | | | | | | | | Purpose: Adding internal shuffle filter Description: With the combination of shuffling filter with general compression algorithm, the compression ratio may be improved without adding much encoding and decoding time for many real NASA datasets(especially floating data) and other application datasets(See techNotes). Solution: SHuffle the bytes within the data to utilize the locality. Platforms tested: arabica , eirene, modi4 Misc. update: Update MANIFEST if you add or remove any file. Update release_docs/RELEASE for bug fixes, new features, etc. Update applicable document files too.
* [svn-r6084] Purpose:Bill Wendling2002-11-123-47/+24
| | | | | | | | | | | FPHDF5 Fixups Description: - Stopped using API calls in the H5FPclient code. It now uses internal library calls. - Removed some FIXME comments because they've been fixed. - Small fix for an enum starting at 37 for no reason :-) Platforms tested: Eirene (only affects FPHDF5, so no need to test 3 platforms just yet).
* [svn-r6077] Purpose:Quincey Koziol2002-11-123-7/+15
| | | | | | | | | | Code cleanup Description: Added some comments and made some minor code cleanups Platforms tested: minor change, only testing on FreeBSD 4.7 (sleipnir) w/parallel
* [svn-r6076] Purpose:Bill Wendling2002-11-121-3/+3

* [svn-r6072] Purpose:Bill Wendling2002-11-112-12/+10
| | | | | | | | | | Code Movement Description: Moved definition of the H5D_t data structure into the H5Dprivate.h header file. With the FPHDF5 stuff, we need access to this data structure. Platforms tested: Eirene...change small, so no need for all three tests.
* [svn-r6071] Purpose:Quincey Koziol2002-11-112-0/+6
| | | | | | | | | | | | Code cleanup Description: Start using the H5_HAVE_FILTER_GZIP macro to enable the gzip filter. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}? Tested FreeBSD 4.7 (sleipnir) also
* [svn-r6070] Purpose:Quincey Koziol2002-11-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | New feature. Description: Add in '--enable-filters=filter1,filter2' flag to configure script. This can also be used as '--enable-filters=all' or just '--enable-filters' to enable all the internal I/O filters in the library. This flag can also be set to '--disable-filters' to disable all the internal I/O filters. Individual filters can not be disabled due to the limitations of autoconf. Additionally, added "H5_HAVE_FILTER_<foo>" macros to H5pubconf.h header file, so the presence of each filter can be detected. This is in preparation for Kent's shuffling filter to be imported shortly. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Tested FreeBSD 4.7 (sleipnir) also
* [svn-r6069] Purpose:Quincey Koziol2002-11-111-1/+1
| | | | | | | | | | | | | Fix Windows portability bug Description: "long long" is not defined on Windows. Solution: Use our internal definition of "long_long" instead. Platforms tested: eyeballed.

| | | | | | | | | | | | | Fix Windows portability bug Description: "long long" is not defined on Windows. Solution: Use our internal definition of "long_long" instead. Platforms tested: eyeballed.
* [svn-r6064] Purpose:Bill Wendling2002-11-071-4/+4
| | | | | | | | | | Code Cleanup Description: A function was returning "NULL" instead of "FAIL" for an error condition. Renamed the variable "class" to "h5_class" since class is a keyword in C++ and might mess up with a C++ compiler... Platforms tested: Eirene pp (too small a change for 3 tests)
* [svn-r6063] Purpose:Quincey Koziol2002-11-072-296/+347
| | | | | | | | | | | Code cleanup Description: Cleaned up some error values that were incorrect, added some assertions and refactored the integer & floating-point native conversions some. Platforms tested: FreeBSD 4.7 (sleipnir), too small for h5committest
* [svn-r6062] Raymond Lu2002-11-073-0/+84
| | | | | | | | | | | | Purpose: New function. Description: H5Dget_offset returns the offset of a dataset's data relative to the beginning of a file. Platforms tested: arabica(simple function, one test should be enough.) Misc. update: RELEASE.txt
* [svn-r6060] Raymond Lu2002-11-065-31/+1110
| | | | | | | | | | | Purpose: Add new functions Description: add H5Tget_native_type and H5Tis_variable_str. Platforms tested: arabica, eirene, modi4 Misc. update: MANIFEST and release_docs/RELEASE updated.
* [svn-r6057] Purpose:Bill Wendling2002-11-058-154/+385
| | | | | | | | | | | | | | | | | | | | | | | New Feature. Support for new FPHDF5 Feature Description: More support for the FPHDF5 feature. This splits the H5D_create function into separate parts which update the metadata cache. It was necessary to split apart the H5O_create function to do a similar thing since it would allocate real space on the hard disk. I'm checking this up now so that I don't get too far away from what the CVS repository has and so that others may look at the code and retch^H^H^H^H^Hmarvel at it. If there are any comments, send them my way. There is one outstanding issue, though. I need to use non-API functions in the FPHDF5 stuff. I'm using some APIs right now and should migrate to using others. At the moment, I'm putting that on the back burner until I'm more along in the implementation. Platforms tested: Arabica (C++) Eirene (Parallel) Modi4 (Parallel)
* [svn-r6055] Purpose:Quincey Koziol2002-11-052-8/+5
| | | | | | | | | | | | | | New feature Description: Add support for scalar dataspaces in parallel I/O. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Also, FreeBSD 4.7 (sleipnir) serial & parallel Misc. update: Update release_docs/RELEASE for bug fixes, new features, etc.

* [svn-r6047] Purpose:Quincey Koziol2002-11-016-1/+24
| | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Hyperslab code for collapsing dimensions was incorrectly collapsing selections inappropriately when the fastest changing dimension couldn't be collapsed. Also add some more assertions which will make similar bugs easier to find. Solution: Break out of loop earlier. Platforms tested: modi4 (parallel), too small to triple check.
* [svn-r6043] Purpose:Quincey Koziol2002-10-291-1/+78
| | | | | | | | | | | | Bug fix Description: I/O using "none" selections in parallel wasn't working correctly. Also, add serial "none" selection test. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}
* [svn-r6041] Raymond Lu2002-10-294-21/+218

* [svn-r6030] Purpose:Bill Wendling2002-10-231-403/+11
| | | | | | | | | | Another Oops Description: I accidentally checked in the H5D.c module when I shouldn't have. Solution: Rolled back to 1.281 version Platforms tested: Linux
* [svn-r6029] Purpose:Bill Wendling2002-10-234-14/+409
| | | | | | | | | | | | Oops Description: The H5FPprivate.h file was being #included even if PARALLEL was turned off. Solution: put the #include of the H5FPprivate.h file within the #ifdef block so that it doesn't get included if H5_HAVE_FPHDF5 isn't defined. Platforms tested: Linux...
