* [svn-r19616] Modfied object header cache client code to update the contents ↵John Mainzer2010-10-151-1/+131
| | | | | | | | | | | | | | | | | | | | | | | | | of the in core image of the on disk representation of the object header on clear as well as on flush. Made this change only in the parallel case, as it causes problems only there, and only with the round robin metadata write strategy in which an object header may be flushed by several different processes in the course of a computation, and marked clean on all other processes on each flush. Note that I made this change to both the H5O_clear() and H5O_cache_chk_clear() cache client callbacks. At present I don't think my fix in H5O_cache_chk_clear() does anything, as I don't think it is possible to dirty a chunk without also marking the associate header dirty as well. However I will leave the fix in as the client code is presently in a state of flux, and it may be a useful reminder. Added test to t_mdset.c to verify the fix. Also added test code to H5C.c and H5AC.c which dumps a listing of all entries in the cache, along with their vital statistics. This code was needed to rule out the possibility of the bug being caused by a failure in the metadata cache -- I leave it in as we may want it again some time.

| | | | | | | | | | | | | | | | As best I can tell, H5C_make_space_in_cache() was accessing memory that had been deallocated -- however the bug was easy to mask, and jumped around even in different runs of the same executable. While I was never able to generate a definitive test case that exposed exactly where the core dump occured, I was able to generate print statement traces which made it clear that I was accessing freed memory. In any case, reworking the code to avoid the reference to freed cache entries seems to have fixed the problem. Tested serial production on Phoenix, and commit tested. Also, partial tests Linew.

* [svn-r14445] Added code to detect the situation in which a metadata cache ↵John Mainzer2008-01-201-35/+501
| | | | | | | | | | | | | | entry flush callback functions modifies the skip list or LRU out from under a partial or complete flush of the cache. This is a test for a situation that should not occur, but we test anyway. Also added code to skip longer tests in cache_api in express tests. Tested serial and parallel on phoenix (debian --x86-32), and commit test. Elena commit tested as well, and ran a manual test under MacOS X.
* [svn-r14442] Modified metadata cache to adapt more quickly to the insertion of aJohn Mainzer2008-01-181-10/+443
| | | | | | | | | | | | | | | | | large entry, or to a large increases in the size of an existing entry. This required some additions to the cache configuration structure, and thus will require changes in the metadata cache documentation. The basic idea is to monitor the size of entries as they are loaded, inserted, or increased in size. If the size of the entry (or increase) exceeds some user selected fraction of the size of the cache, increase the size of the cache. Note that this fix was designed quickly -- while it deals with the use case that exposed the problem, we may have to revisit the issue later. Tested serial and parallel on Phoenix, and h5committest.

* [svn-r12774] Modified flush code in the metadata cache to allow it toJohn Mainzer2006-10-181-148/+813
| | | | | | | | | | | | | | | | | 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.
* [svn-r12706] Description:Quincey Koziol2006-10-021-1/+1
| | | | | | | | | Clean up some of the warnings on 64-bit Linux... Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2) Too minor to require h5committest

| | | | | | | | | | | 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 Mainzer2006-07-131-8/+375
| | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | 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/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r12311] Purpose:John Mainzer2006-04-281-372/+1277
| | | | | | | | | | | | | | | | | | | | | | | | | 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-r11470] Purpose:John Mainzer2005-09-271-25/+1028
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Repair synchronization bug in the metadata cache in PHDF5 Also repair numerous other bugs that surfaced in testing the bug fix. Description: While operations modifying metadata must be collective, we allow independant reads. This allows metadata caches on different processes to adjust to different sizes, and to place the entries on their dirty lists in different orders. Since only process 0 actually writes metadata to disk (all other processes thought they did, but the writes were discarded on the theory that they had to be collective), this made it possible for another process to modify metadata, flush it, and then read it back in in its original form (pre-modification) form. The possibilities for file corruption should be obvious. Solution: Make the policy that only process 0 can write to file explicit, and visible to the metadata caches. Thus only process 0 may flush dirty entries -- all other caches must retain dirty entries until they are informed by process 0 that the entries are clean. Synchronization is handled by counting the bytes of dirty cache entries created, and then synching up between the caches whenever the sum exceeds an (eventually user specified) limit. Dirty metadata creation is consistent across all processes because all operations modifying metadata must be collective. This change uncovered may bugs which are repaired in this checkin. It also required modification of H5HL and H5O to allocate file space on insertion rather than on flush from cache. Platforms tested: H5committest, heping(parallel & serial) Misc. update:
