aa96180fa9 [svn-r13690] Description:
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)

030543bf0d [svn-r13618] Modified metadata cache to support multiple read only protects of
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.

ed7d456e51 [svn-r13253] Updated all C and C++ style source code files with the THG 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.

2d6bb59329 [svn-r12774] Modified flush code in the metadata cache to allow it to
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.

a6f6462541 [svn-r12700] Alert:
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

Clean up some compiler warnings by removing "UNUSED" from function
prototypes.

Tested on:
    Linux 2.? (tg-login3)
    Too minor to require h5committest

e8c1fdd554 [svn-r12595] Modified H5C_insert_entry() to accept the H5C__PIN_ENTRY_FLAG entry
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)

801b5b09f2 [svn-r12462] Committed a variety of metadata cache related changes:
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).

7be3afb278 [svn-r12440] Purpose:
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

a415cc6b17 [svn-r12374] Purpose:
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.

eb96132022 [svn-r12316] Purpose:
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

8a7b9b3221 [svn-r12311] Purpose:
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.

c18b328ff1 [svn-r11903] Purpose:
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.
