* [svn-r13690] Description:Quincey Koziol2007-04-191-1/+0
| | | | | | | | | | | | | Fully enable readers/writer locking in metadata cache and correct errors in cache clients which were modifying a cache entry while only holding a read lock on it. Tested on: Mac OS X/32 10.4.9 (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2) FreeBSD/32 6.2 (duty) FreeBSD/64 6.2 (liberty)
* [svn-r13618] Modified metadata cache to support multiple read only protects of John Mainzer2007-04-091-6/+301
| | | | | | | | | | cache entries. Added test code to test the new feature. Also some minor cleanum h5committested -- passed on copper and sol. Failed on osage with a configuration error that appears unrelated to my changes. Serial test (debug mode) passes on Phoenix (Linux x86 2.6 kernel), so I went ahead with the checkin.
* [svn-r13253] Updated all C and C++ style source code files with the THG ↵Albert Cheng2007-02-071-2/+3
| | | | | | | | | copyright notice. Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.

* [svn-r12774] Modified flush code in the metadata cache to allow it toJohn Mainzer2006-10-181-39/+872
| | | | | | | | | | | | | | | | | handle flush callbacks which can dirty other entries, and resize and/or rename the target entry. This feature is needed by the fractal heap code. Also added associated test code. H5Commit tested. Test failed on heping, but the error appears to be a syntax error in an un-related file. Tests on copper & sol passed, along with tests on phoenix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | File format is not stable, don't keep files produced! Description: First stage of checkins modifying the format of groups to support creation order. Implement "dense" storage for links in groups. Try to clarify some of the symbols for the H5L API. Add the H5Pset_latest_format() flag for FAPLs, to choose to use the newest file format options (including "dense" link storage in groups) Add the H5Pset_track_creation_order() flag for GCPLs, to enable creation order tracking in groups (although no index on creation order yet). Remove --enable-group-revision configure flag, as file format issues are now handled in a backwardly/forwardly compatible way. Clean up lots of compiler warnings and other minor formatting issues. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/FORTRAN & C++ Linux/64 2.4 (mir) w/enable-v1.6 compa Mac OSX/32 10.4.8 (amazon) AIX 5.3 (copper) w/parallel & FORTRAN
* [svn-r12620] Description:Quincey Koziol2006-08-231-5/+5
| | | | | | | | | Clean up some compiler warnings by removing "UNUSED" from function prototypes. Tested on: Linux 2.? (tg-login3) Too minor to require h5committest
* [svn-r12595] Modified H5C_insert_entry() to accept the H5C__PIN_ENTRY_FLAG entryJohn Mainzer2006-08-171-0/+18
| | | | | | | | | | | flag, and pin an entry as it is inserted. The objective is to avoid some function call overhead in fheap. Also added matching test code in test/cache.c & test/cache_common.c (also testpar/t_cache.c checked in separately by accident) h5commit tested
* [svn-r12462] Committed a variety of metadata cache related changes:John Mainzer2006-07-131-1/+64
| | | | | | | | | | | | | | | | | | | | | | 1) Added trace file support to the metadata cache. This allows capture of all metadata cache calls in trace files for purposes of optimization and debuging. 2) Added an expunge entry function. This allows an entry to be deleteded from the cache without writing it to disk even if it is dirty. 3) Added a function call to resize pinned entries. 4) Added code to deal with entries that are dirty on load. This is needed in support of a bug fix which can alter object headers on load to repair files. 5) Added progress reporting code to the "MDC API smoke check" test in cache_api.c. To enable the progress reporting, set report_progress to TRUE in mdc_api_call_smoke_check(). Tested with h5committest, and a parallel test on phoenix (dual athelon linux box).
* [svn-r12440] Purpose:Quincey Koziol2006-06-271-31/+31
| | | | | | | | | | | Code cleanup Description: Trim trailing whitespace in Makefile.am and C/C++ source files to make diffing changes easier. Platforms tested: None necessary, whitespace only change
* [svn-r12374] Purpose:John Mainzer2006-05-241-0/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Check in potential fix to unreproduceable bug in t_cache observed on Cobalt 2) Check in code supporting added pinned entry features in the metadata cache. Description: 1) Elena encountered a bug in t_cache when running on Cobalt. On investigation I found a potential race condition in t_cache that could explain her observation. 2) Quincey requested additions to the metadata cache allowing renaming of pinned entryies, and marking of pinned or protected entries as dirty. Solution: 1) Modified t_cache.c to prevent the potential race condition. Elena was unable to reproduce the bug on Cobalt, so we don't know if my fix actually addressed the problem. 2) Added code supporting the requested functions. The changes were relatively trivial, but required substantial new test code. Platforms tested: h5committest, serial test on heping, parallel test on phoenix. Misc. update:
* [svn-r12316] Purpose:Quincey Koziol2006-04-291-3/+3
| | | | | | | | | | | | | | | Code cleanup/feature twist Description: Adjust recent H5AC routines to take H5F_t pointers instead of H5C_t pointers, to match the rest of the H5AC routines. This change propagated into a few of the tests, which also had some compiler warnings cleaned up... Platforms tested: FreeBSD 4.11 (sleipnir) w/parallel Linux 2.4/64 (mir) w/C++ & FORTRAN
* [svn-r12311] Purpose:John Mainzer2006-04-281-3/+330
| | | | | | | | | | | | | | | | | | | | | | | | | Add pinned entry capability to cache. Description: For frequently accessed cache entries, the protect/unprotect overhead is sometimes a bottleneck. Solution: Allow entries to be pinned in the cache. Pinned entries can't be evicted, but can be flushed or modified. Platforms tested: h5committested -- minus one small typo in test/cache.c whose fix was tested on copper and heping only. Misc. update:
* [svn-r11903] Purpose:John Mainzer2006-01-291-0/+2878
Add files that I forgot in my last checkin. Description: cache_api.c cache_common.c cache_common.h are new files that result from breaking the old cache test into two tests. Solution: See above. Platforms tested: h5committested before the last checkin. Will run another h5committest shortly, but it shouldn't be necessary as there are no new changes. Misc. update:
