Also, further discriminate between 'closing' and 'non-closing' actions in H5F_flush. r17412: Seperate 'flush' functionality from 'destroy' functionality at the H5F level also. r17413: Remove vestigial intermediate routine for flushing file and move it into API routine. Also, remove private, unused (now) 'H5F_FLUSH_DOWN' symbol from public header file. r17414: Flush the core VFD's buffer before closing the file, also flush the metadata accumulator before reseting it. Write the driver info message out in the superblock flush routine more directly, instead of using wrapper routine, since the wrapper routine won't work when the superblock is being shutdown.

| | | | | | | | | | | | | | | | reference count > 1. Description: Added a new field 'app_count' to H5I_id_info_t struct, to track the reference count on an id due to the application. the old 'count' field tracks the total. Generally any id visible to the application gets placed in app_count. Added app_ref boolean parameter to H5I_inc_ref, H5I_dec_ref, H5I_register, H5I_clear_type, and a few other functions, to specify whether the operation(s) being performed on the id(s) are due to the application (TRUE) or not (FALSE). Test added for this case. Tested: kagiso, smirom, linew (h5committest)

* [svn-r14442] Modified metadata cache to adapt more quickly to the insertion of aJohn Mainzer2008-01-181-2/+21
| | | | | | | | | | | | | | | | | 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-r14065] Second try at checking in the "cork the cache" modification.John Mainzer2007-08-101-23/+10
| | | | | | | | First attempt contained slightly dated versions of the files listed below. Must also note that the mods were tested with h5committest, and two other linux builds.
* [svn-r14064] Implemented function allowing the user to cork the metadata cache.John Mainzer2007-08-101-49/+77
| | | | Also implemented associated test code.
* [svn-r13745] Description:Quincey Koziol2007-05-101-0/+4
| | | | | | | | | | | | Take further advantage of the readers/writer locking in the metadata cache and push the locking of the local heap up to the routines which call B-tree routines, which should drastically lower the number of metadata cache protect/ unprotect calls. Tested on: Mac OS X/32 10.4.9 (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r13618] Modified metadata cache to support multiple read only protects of John Mainzer2007-04-091-5/+36
| | | | | | | | | | 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.

| | | | | | | | | 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-r12902] Checkin of Shared Object Header Message work.James Laird2006-11-131-0/+2
| | | | | | | | | | | | This feature is still in progress; Shared Object Header Messages are not complete as a feature and are not thoroughly tested. There are still "TODO" comments in the code (comments with the word "JAMES" in them, so as not to be confused with other TODO comments). Hopefully this checkin will reduce the liklihood of conflicts as I finish implementing this feature. All current tests pass on juniper, copper (parallel), heping, kagiso, and mir.
* [svn-r12596] Refactored how external files are opened and closed.James Laird2006-08-181-0/+1
| | | | | | | | Object header locations (H5O_loc_t's) can now "hold open" a file and decrement its open object count when they close. This means that locations (H5O_loc_t's and H5G_loc_t's) should always be freed. Added more thorough tests to ensure that external files are closed.

* [svn-r12462] Committed a variety of metadata cache related changes:John Mainzer2006-07-131-14/+883
| | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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:

| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest

* [svn-r11014] Purpose:Quincey Koziol2005-07-021-5/+5
| | | | | | | | | | | | Code cleanup Description: Refactor metadata cache to merge "dirtied" flag in with other flags for H5AC_unprotect and H5C_unprotect. Platforms tested: FreeBSD 4.11 (sleipnir) h5committest

| | | | | | | | | | | | | | | | | | | | | | | | | | | Interim checkin of code changes moving management of the is_dirty flag into the cache code. Description: Prior to this checkin, management of the is_dirty flag was handled above the level of the metadata cache. This can no longer be allowed, as it introduces a race condition in the proposed fix for a cache coherency bug in PHDF5. Solution: Move management fo the is_dirty flag to the cache code proper. Entries are now marked as dirty via a flag on the unprotect call. Platforms tested: h5committested Misc. update:
* [svn-r10715] Purpose:John Mainzer2005-05-021-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | Remove C99 types from new metadata cache related API calls Description: Windows (and perhaps others) don't like int32_t and int64_t. While we have dealt with the issue internally, it is more of a problem in API calls. Solution: Convert int32_t to int and int64_t to long int in the H5AC_cache_config_t structure used by the new metadata cache related API calls. Added explicit type casts to convert between internal and external representations. Platforms tested: h5committested Misc. update:
* [svn-r10688] Purpose:John Mainzer2005-04-281-66/+452
| | | | | | | | | | | | | | | | | | | | | | | | | | Add API calls allowing user control of the metadata cache. Description: Prior to this update, the metadata cache was not configurable from outside the library. Solution: Add API calls allowing the user to configure the metadata cache either at file open time, or for any open file. Also added calls permitting the user to monitor cache size and hit rate. These latter facilities are needed for "manual" cache size control Platforms tested: h5committested Misc. update:
