1023374492 [svn-r27768] Description:
Complete revamp of package initialization/shutdown mechanism in the library.
Each package now has a single init/term routine.

    This new way should avoid packages being re-initialized during library
shutdown and is also be _much_ more proactive about giving feedback for
resource leaks internal to the library.

    Introduces a new "module" header file for packages in the library
(e.g src/H5Fmodule.h) which sets up some necessary package configuration macros
for the FUNC_ENTER/LEAVE macros.  (The VFL drivers have their own slightly
modified version of this header, src/H5FDdrvr_module.h)

    Also cleaned up a bunch of resources leaks all across the library and tests,
along with addressing many warnings, as I encountered them.

Tested on:
    MacOSX/64 10.10.5 (amazon) w/serial & parallel
    Linux/64 3.10.x (kituo) w/serial & parallel
    Linux/64 2.6.x (ostrich) w/serial

f97d63cb95 [svn-r24869] Description:
Clean up more compiler warnings, plus merge a few Coverity bug fixes from
the hdf5_1_8_coverity branch back to the trunk:

r20877:
Purpose: Fix coverity issue 1723

Description:
Modified test_generate in hl/test_image to close file "f" before exit, even if
an error occurs.

r20879:
Issue 63: change check of return of H5Tget_nmembers to <=0. No need to go
futher if call fails as well as empty.

r20881:
Coverity #659 in Run 46: I changed the Line 442 where it tries to check whether
FLAG_PRINTED is TRUE.  But it had just been set to FALSE.  I took out the
condition check in the print statement.

Tested on:
    Mac OSX/64 10.9.2 (amazon) w/C++, FORTRAN & Parallel
    (too minor to require h5committest)

863ff882b6 [svn-r24709] rename H5V to H5VM since H5V is needed in the fastforward project for
view objects.  The addition of view objects in the fastforward project
is expected to be brough into the trunk sometimes in the future, which
is why we need to make this change.

Tested Manually on Jam and Ostrich.
Tested with h5commitest - Koala with intel compilers failed, but nothing had to do with those changes.

9f18db936f [svn-r22103] Fix for HDFFV-7769 (HDF5 tests time out on Windows when core VFD is set).
This occurs due to the istore test creating very large files on systems which
do not have POSIX-like sparse file semantics.  The large amount of I/O causes
the test to run for a very long period of time.

The fix was to copy the "big" test's sparse file check and only run the
largest sparse file test when POSIX-like sparse file semantics are found.

Tested on:

jam (nfs)
ostrich (nfs)
loyalty (ufs)
64-bit linux VM (ext4)
64-bit OS-X Lion (hfs, detected as not POSIX sparse)
64-bit Windows 7 (NTFS, detected as not POSIX sparse)

The OS-X failure to pass the sparse check is likely an error and will be
entered as a new bug.

    Correct a number of our tests which were creating datasets with chunks
that were >4GB and add some specific tests for >4GB chunk size detection.

Description:
    Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation.  So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.

    I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".

Purpose: Maintenance and bug fixes and test of latest szip library..

Description:  Recently Quincey enabled MEDIUM test for istore. That caused
              daily tests to fail on verbena. It looks like that test
              creates a pretty big file, and afs write fails. Test passes
              when run in /tmp.

Solution: Disable MEDIUM test and filed bug report to investigate the problem
          little bit more carefully.

Platforms tested: verbena, arabica, arabica-64 (since I also tested newest szip)

New feature/enhancement

Description:
    Chunked datasets are handled poorly in several circumstances involving
certain selections and chunks that are too large for the chunk cache and/or
chunks with filters, causing the chunk to be read from disk multiple times.

Solution:
    Rearrange raw data I/O infrastructure to handle chunked datasets in a much
more friendly way by creating a selection in memory and on disk for each chunk
in a chunked dataset and performing all of the I/O on that chunk at one time.

    There are still some scalability (the current code attempts to
create a selection for all the chunks in the dataset, instead of just the
chunks that are accessed, requiring portions of the istore.c and fillval.c
tests to be commented out) and performance issues, but checking this in will
allow the changes to be tested by a much wider audience while I address the
remaining issues.

946c606452 [svn-r6411] Purpose:
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.

24d8506dd5 [svn-r6387] Purpose:
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)}

9a433b99a5 [svn-r6252] Purpose:
Lots of performance improvements & a couple new internal API interfaces.

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.

	modi4 (parallel, fortran)}
