* [svn-r6589] Elena Pourmal2003-04-053-34/+45
| | | | | | | | | | | | | | | | | | | | | Purpose: Bug fix Description: h5import tests will fail if srcdir option is used with configure. Solution: Modified h5importtest.c h5importtestutil.sh files to search for input files in the proper directory and to write output files to the proper directory. Platforms tested: Tested on burrwhite, arabica, and modi4. Unfortunately srcdir option was used only on arabica, since I am having a weird 'timezone' problem on all Linux machines when srcdir is used, and on modi4 build has to be done in the same directory (at least this is a message I am getting from configure; should it work?) Misc. update:

* [svn-r6584] Elena Pourmal2003-04-032-15/+148
| | | | | | | | | | | | | | | | Purpose: Maintenance Description: There was an old h5import (h5import.c) tool in the misc directory. The tool created 8-bit integer datasets , it was never tested and/or supported. Solution: We decided to rename old h5import.c to h5createU8.c. The new name reflects what actually old tool does. New executable h5createU8 is built in the misc directory. h5import.c file (old one) is still in the misc directory, but h5import executable is not built. (Sorry if I confused you!) Platforms tested: vebena, arabica, modi4 were tested Misc. update:

| | | | | | | | | | | | | | | | | | | Purpose: New tool Description: Pankaj created h5import tool long time ago. I am finally checking the source code in for the 1.6 release. Known problems: h5import test will crash if srcdir option is used; will be fixed before the release. Solution: Platforms tested: vebena, arabica, modi4 were tested. h5import tests passed I also tested on arabica with srcdir option to make sure that there is a problem when srcdir is used. After that I disabled h5import tests. Daily tests will build h5import, but will not run h5import tests. Misc. update:

* [svn-r6411] Purpose:Quincey Koziol2003-02-172-10/+11
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up miscellaneous warnings which have crept into the code. Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD. Adjust gcc compiler flags to be more concise for production mode. Refactor the H5O code so that there is a stronger boundary between code in the H5O package and code in the library which just calls H5O routines. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2 Misc. update: Update MANIFEST if you add or remove any file.
* [svn-r6404] Purpose:Bill Wendling2003-02-141-2/+11
| | | | | | | | | | | | | | | | Bug Fix (Bug #806) Description: When compiling/installing with the command "make install" (without performing a "make" beforehand) the tools weren't being made. This was because the `install' command in the Makefiles only relied upon public libraries, not private ones (which the one in the tools directory is). Solution: Had the `install' command be dependent upon an "AUX_LIB" macro which includes libraries which are needed but aren't distributed (that is, they're staticly compiled). Platforms tested: Linux
* [svn-r6398] Purpose:Quincey Koziol2003-02-121-1/+1

* [svn-r6387] Purpose:Quincey Koziol2003-02-101-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel Misc. update: Updated release_docs/RELEASE

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?
