* [svn-r6330] Purpose:Quincey Koziol2003-01-241-0/+2
| | | | | | | | | | | | | | | Bug Fix Description: When calling H5Fopen with the core VFL driver, but without the H5F_ACC_CREAT flag goes ahead and creates a memory file. Solution: Check for the H5F_ACC_CREAT flag before allowing the memory file to be created. Platforms tested: FreeBSD 4.7 (sleipnir)
* [svn-r6313] Purpose:Albert Cheng2003-01-221-8/+23
| | | | | | | | | | | Updated Description: Updated Copyright notice. Replaced HGOTO_ERROR calls involving MPI calls with HMPI_GOTO_ERROR. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}? Tested on Eirene (PP) only since the code is in the MPIO module only.
* [svn-r6308] Purpose:Quincey Koziol2003-01-215-11/+375
| | | | | | | | | | | | | | | | | Bug fix Description: Currently, when the library encounters an object header message that isn't know, it fails to open that object in the file. Solution: Allow the library to skip over the unknown object header message and continue to process the remaining messages, in the hope that the skipped message isn't important later. If it is important, it will be caught at a higher level of the library. Platforms tested: FreeBSD 4.7 (sleipnir)

* [svn-r6252] Purpose:Quincey Koziol2003-01-0987-3062/+6559
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested? FreeBSD 4.7 (sleipnir) serial & parallel Solaris 2.6 (baldric) serial
* [svn-r6232] Purpose:Albert Cheng2003-01-035-5/+467
| | | | | | | | | | | | | | | | new feature Description: Added MPICH/MPE instrumentation support. All source code are bracketed by the macro H5_HAVE_MPE. Use "--enable-mpe" to configure it in. Currently only worked in Eirene because the MPE library is not installed in all machines yet. The added file, H5MPprivate.h, holds HDF5/MPE related defintions. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}? Yep. Other platforms/configurations tested? --enable-mpe feature tested in Eirene.
* [svn-r6229] Purpose:Albert Cheng2003-01-031-1/+2
| | | | | | | | | | | Minor fix Description: By mistake, the MPI_Error handling macros were inserted outside the overall macro bracket. Moved them back inside the bracket. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}? Yep.
* [svn-r6228] Description:Albert Cheng2003-01-031-3/+0
| | | | | | | | When I removed the option (--enable-parallel=mpich), which did not work, I failed to run autoheader to update this file. I am checking in the updated version now. Platforms tested: No need to test since it just removed a #undefine and comments.
* [svn-r6223] Purpose:Binh-Minh Ribler2002-12-222-8/+8
| | | | | | | | | | | | | | | | | | | | | | Bug fix - informed by Kent Description: Some identifiers were flagged as unresolved symbols when building with c++ on Windows. The reason is the name of these identifiers were changed by the c++ compiler, also called name mangling. Solution: Moved #ifdef __cplusplus extern "C" { #endif to include the offending identifiers so the c++ compiler will take them as is. Platforms: SunOS 5.7 (arabica) Linux 6.2 (eirene) Windows 2000

* [svn-r6220] Purpose:Bill Wendling2002-12-194-156/+299
| | | | | | | | | | Update Description: A few generic changes to the FPHDF5 code. Some error messages reworked a bit. Cleaning up in case of failure improved in some cases. Added another field to the synchronization messages... Platforms tested: Linux
* [svn-r6219] Purpose:Bill Wendling2002-12-191-1/+0
| | | | | | | | | Update Description: Removed the EFL field from the FPHDF5 structure as the property list already has this info. Platforms tested: Linux
* [svn-r6218] Purpose:Bill Wendling2002-12-191-47/+17
| | | | | | | | | | Bug Fix Description: Was encoding a value as DTYPE instead of MTIME, which would cause a couple of errors. Also, got rid of the EFL field as it's encoded in the PLIST already... Platforms tested: Linux...Modest test, FPHDF5 not fully implemented just yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | 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.
