31431be374 [svn-r7917] Purpose:
Code cleanup

Description:
    Clean up compiler warnings, especially the 'FUNC' variable not used which
comes out in production mode.

Solution:
    Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API
functions which don't need the 'FUNC' variable defined.  (This will be _so_
much easier when C99 is standard on all our supposed platforms, since it has a
__FUNC__ macro... )

Platforms tested:
    FreeBSD 4.9 (sleipnir)
    too minor for h5committest (although there were lots of files changed, the
        change was minor in each one)

Update

Description:
    A lot of modifications for the FPHDF5 stuff:

        H5AC.c
        H5ACprivate.h - Removed AC_find (it's replaced with AC_protect
        and AC_unprotect). Added flushing if it's an FPHDF5 driver and
        we're doing an AC_set or AC_unprotect with the dirty flag set.

        H5B.c - Split up the B_flush function into different functions
        since the one function was doing serialization which is better
        left as a separate entity.

        H5D.c - Removed some FPHDF5 code that was incorrect

        H5F.c - Split up the F_flush function so that it no longer
        allocates file space. Created new functions (F_init_superblock,
        F_read_superblock, and F_write_superblock) for greater modularity
        and so that the FPHDF5 non-captain processes can read the
        superblock after the captain process writes it.

        H5FD.c - Error message correction.

        H5FDfphdf5.c - Removed MPI barrier call that wasn't needed.

        H5FPclient.c
     	H5FPserver.c - Modified so that if a process requests data that
        isn't exactly aligned, we can return it if we have the block that
        contains the requested address.

        H5G.c
        H5Gent.c
        H5Gnode.c
        H5HL.c
     	H5HLpkg.h
        H5HLprivate.h
        H5Oefl.c - Removed the H5HL_peek function since it was doing a
        (now unsafe) holding of the information in the cache. Replaced
        with protect and unprotect calls.

        H5TB.c - Error fix. The TB_dless function wasn't working
        properly.

        H5Gstab.c - Format change.

        H5err.txt
        H5Edefin.h
        H5Einit.h
     	H5Epubgen.h
        H5Eterm.h - Added new error code.

1f5e8c2e63 [svn-r7460] Purpose:
Update

Description:
    Added extra parameter to the H5AC_protect() function that indicates
    if the cache being asked for is going to be written to or just read
    from. Those AC_protect calls that were H5AC_find calls are now
    read-only. The rest are writes.

6d928cf05e [svn-r7456] Purpose:
Removal of H5AC_find()

Description:
    The H5AC_find() function is mostly redundant and with the new
    Flexible Parallel HDF5 stuff, we need to do locking on metadata
    returned from the H5AC_find() anyway. So, all of the locking stuff
    will be placed in the H5AC_{un}protect() functions. The H5AC_find()
    is no longer needed.

Solution:
    Replaced all H5AC_finds with H5AC_protects and H5AC_unprotects.

bd34662948 [svn-r7445] Purpose:
Fix, of a sort

Description:
    Some of the code would get an object from the cache via the
    H5AC_find() function and then modify the returned object. This
    behavior is incorrect as the pointer returned via the H5AC_find()
    function is supposed to be read only.

Solution:
    Changed the H5AC_finds to H5AC_protect() instead and added the
    appropriate H5AC_unprotect() function.

da1e2ca089 [svn-r7369] Purpose:
Bug fix

Description:
    The metadata cache 'destroy' callback routines need the file handle in
order for certain callback routines (currently just the H5HG one) to perform
extra cleanups.  The recent change to call the 'destroy' callback from the
'clear' callback omitted this parameter.

Solution:
    Add the file handle to the metadata cache 'clear' callbacks.

ad13ea65ab [svn-r7367] Purpose:
Update

Description:
    Added an extra flag to the clear functions that triggers a "destroy"
    of the object being cleared if necessary. This is a fix for the
    FPHDF5 stuff which had an object sticking around after it was
    cleared. (In FPHDF5, some processes are in charge of destroying the
    object, but all processes might actually allocate the object.)

Code cleanup, bug fix & new feature.

Description:
    The local heaps were missed in the last changes to the metadata "dirty"
flag, making them operate incorrectly in the metadata cache.  Fixed by changing
to use "cache_info.dirty" flag instead.

    Track changes for internal metadata API, regarding marking metadata as clean
without flushing it to the file.

    Added ability to delete a local heap in the file.

    Added ability to reduce the size of a  local heap if there is a free-space
block at the end of the heap and the free-space block is over half the size of
the local heap.

    Some migration of package-specific information out of the private header
and into the code module as well.

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.

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.

99eee6dff9 [svn-r5814] Purpose:
Bug Fix

Description:
    It was possible to create corrupted metadata information (either in memory
    or in the file or both) with a parallel I/O program because of the way
    metadata writes were being handled for writes out of the metadata cache.

Solution:
    Added a dataset transfer property called "block before metadata write"
    which is used by the MPI-I/O and MPI-posix drivers to sync up all the
    processes before attempting a metadata write.  This property is currently
    only for metadata writes from the metadata cache.

Code cleanup

Description:
    Broke the FUNC_ENTER macro into several macros, with more specialized
    uses (which followup mail will describe).  This was designed to move
    most/all of the checks which could be done at compile time to that point,
    instead of needlessly performing them (over & over :-) at run-time.
    This reduces the library's size (and thus staticly linked binaries) and
    has a minor speedup effect also.

Platforms tested:
    IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing
    on FreeBSD and Solaris immediately after the checkin.

ca912c389e [svn-r5467] Purpose:
Code cleanup.

Description:
    Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros
    equivalents in the SAF library and adapted them to our library.  I added
    an additional macro which is equivalent to FUNC_ENTER:
        FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but
            none of the library or interface initialization code.  This is to
            be used _only_ for static functions and those which explicitly
            cannot have the library or interface initialization code enabled
            (like the API termination routines, etc.).

    This allowed many more of the functions in the library [but not all yet :-(]
    to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs.

    It also reduced the size of the library and executables (by cutting out a
    bunch of code which was never executed), I'll e-mail the exact results when
    I've finished editing it.

9815305745 [svn-r5390] Purpose:
Code cleanup

Description:
    The parallel I/O file driver is optimized to only write metadata with one
    process (and broadcast the results to the other processes).  This is
    currently enabled by a separate call to H5FD_mpio_tas_allsame() before
    each metadata write to the file.  This can easily lead to problems where
    the prelude function call is omitted before the actual write code or, in
    a threaded environment, lead to race condititions where the value set is
    reset before being used.

Solution:
    Since we only want to write metadata from one process, key off of the 'type'
    parameter (which has information about whether the data being written it
    metadata or raw data) to H5FD_mpio_write() as the method for determining
    whether to only write from one process or not.

        we incremented enum's with the ++ operator.
Solution:
    Changed variables, etc.to avoid C++ keywords (new, class, typename, typeid,
        template)

    Fixed usage of UNUSED macro from this:
        char UNUSED *c
    to this:
        char * UNUSED c

    Switched the enums from x++ to x=x+1

Code cleanup (sorta)

Description:
    When the first versions of the HDF5 library were designed, I remembered
    vividly the difficulties of porting code from a 32-bit platform to a 16-bit
    platform and asked that people use intn & uintn instead of int & unsigned
    int, respectively.  However, in hindsight, this was overkill and
    unnecessary since we weren't going to be porting the HDF5 library to
    16-bit architectures.

    Currently, the extra uintn & intn typedefs are causing problems for users
    who'd like to include both the HDF5 and HDF4 header files in one source
    module (like Kent's h4toh5 library).

Solution:
    Changed the uintn & intn's to unsigned and int's respectively.

95862451f7 [svn-r4324] Purpose:
New Features!
Description:
    Start migrating the internal use of property lists in the library from the
    older implementation to the new generic property lists.

    Currently, only the dataset transfer property lists are migrated to the
    new architecture, all the rest of the property list types are still using
    the older architecture.

    Also, the backward compatibility features are not implemented yet, so
    applications which use dataset transfer properties may need to make the
    following changes:
        H5Pcreate(H5P_DATASET_XFER) -> H5Pcreate_list(H5P_DATASET_XFER_NEW)
            and
        H5Pclose(<a dataset transfer property list>) -> H5Pclose_list(id)

    This still may have some bugs in it, especially with Fortran, but I should
    be wrapping up those later today.

Code clean/bug fix
Description:
    H5FL (free-list manager) code currently is taking an hsize_t as the size
    of a memory block to allocate.  On many machines, the size of an hsize_t
    is greater than the size of a size_t, potentially leading to incorrect
    memory allocations in rare circumstances.

cbf68fc824 [svn-r1568] Changes since 19990730
----------------------

This extensive change is the virtual file layer implementation. I've
ported and tested the sec2, family, and core drivers and only ported
the mpio driver (Albert will test it).  So if you need MPIO I would
recommend sticking with the previous version for a while.

You will get a few compile warnings about split and stdio drivers not
being implemented and possibly tracing information not inserted in
some of the drivers. You can safely ignore them but I plan to fix
them.

I'm still working on the split driver because I just realized that it
needs a part of the VFL that isn't written yet.

Documentation is being updated also because there were some minor
changes (mostly just name changes). It should be available on my web
site later this week.

	Modified to work with the virtual file layer by calling H5FD_*
	functions instead of H5F_low_* functions and by passing file
	access and data transfer properties by object ID instead of
	pointer.

	Changed H5D_transfer_t to H5FD_mpio_xfer_t since the
	COLLECTIVE vs. INDEPENDENT transfer mode is specific to the
	MPIO file driver.

	Moved MPIO-specific stuff into the MPIO driver.

./src/H5B.c
./src/H5D.c
./src/H5Fprivate.h
	The H5F_mpio_* private functions were renamed and placed in
	the H5FDmpio driver except those which appeared in H5Smpio.c.

./src/H5E.c
./src/H5Epublic.h
	Added major error number H5E_VFL for virtual file layer
	related errors.

./src/H5F.c
./src/H5Fprivate.h
	Changed the logic that controls whether the boot block is
	written. Instead of assuming that the first call to write the
	boot block is only to allocate space, I've added a function
	argument which makes this explicit.

	Changed the way files are compared so that a driver-defined
	comparison function can be called.  Files which belong to
	different drivers are always considered different.

	Removed H5F_driver_t since file drivers are now identified by
	object ID instead of a special non-user-extendible datatype.

	Removed all the hard-coded low-level file properties which
	have been replaced by the various file drivers.

./src/H5I.c
./src/H5Iprivate.h
	Added the H5I_inc_ref() which was removed a few months ago
	since we finally have a use for it.

./src/H5Ipublic.h
	Added the H5I_VFL object ID type to identify file drivers in
	the virtual file layer.

./src/H5MF.c
./src/H5MFprivate.h
	Moved all the allocation/deallocation code into the virtual
	file layer which allows file drivers to override much of it.

./src/H5P.c
./src/H5Ppublic.h
	Moved file driver-specific code into the various file driver
	files.

	The H5Pcopy() and H5Pclose() functions make calls into the
	virtual file driver to manage the memory for driver-specific
	file access and data transfer properties.

./src/H5private.h
./src/H5public.h
	The `haddr_t' type is now public.

./test/tfile.c
	Added a few more comments.

	Most of these changes are because the `interface_initialize_g'
	variable change from hbool_t to int.  It's a one line change.

	Changed the way the library is closed so we have more control
	over the order the interfaces are shut down.  Instead of
	registering an atexit() function for every interface in some
	haphazard order we just register one: H5_term_library() which
	then calls the H5*_term_interface() functions in a
	well-defined order.

	If the library is closed and then reopened repeatedly by
	calling H5close() and H5open() in a loop we only add one copy
	of the library termination functions with atexit().

	Termination is a two-step process in order to help detect
	programming errors that would cause an infinite loop caused by
	the termination of one interface waking up some other
	previously terminated interface.  The first step terminates
	the interface and *marks it as unusable*.  After all
	interfaces are terminated then we mark them all as usable
	again.  The FUNC_ENTER() macro has been modified to return
	failure or to dump core (depending on whether NDEBUG is
	defined) if we try to call an interface while it's shutting
	down.

./src/H5.c
	The H5dont_atexit() function returns failure if it's called
	more than once or if it's called too late.  However, the error
	stack is not automatically printed on failure because the
	library might not be initialized yet

./test/flush2.c

./test/ragged.c
	Changed the extra cast for Win32 so we do floating point
	division again -- it was just confusion about precedence and
	associativity of casting and the C coercion rules. Removed
	extra carriage returns inserted by broken operating system.

./src/H5Ffamily.c
	Fixed an bug where H5F_fam_write() lowered the EOF marker for
	one of the family members causing H5F_fam_read() to read
	zeros.

	Support library for test files.  This isn't done yet but
	Katie's contractions are ~10 minutes apart so I figured I
	better back this stuff up just in case I'm not here next
	week...

	Eventually all test files will understand HDF5_DRIVER to name
	the low level file driver and parameters so we can easily test
	various drivers.  They will also understand HDF5_PREFIX to
	prepend to the beginning of file names which is necessary for
	testing ROMIO with various drivers. Also, the cleanup function
	will know how to use the file name prefix and will understand
	different file driver naming schemes like file families. I'm
	not sure they'll understand the `gsf:' type prefixes yet.

	Note, the external test is completely commented out because
	I'm in the middle of modifying it.  It will still compile and
	run but it doesn't test anything at the moment.

----------------------

./INSTALL.parallel	[NEW]
	We're beginning to unify some of the parallel installation
	steps.  This file will contain general information for
	installing the parallel library.  It's not complete yet.

./configure.in
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
	Check for xdr_int() in libnsl required on Solaris when linking
	with hdf4.  It's found on the Irix system I tested which
	complains that `-lnsl' didn't resolve any symbols. Oh well.

	Fixed the order of searching for libdf and libmfhdf for hdf4
	linking.

./configure.in
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
./src/H5Z.c
	Check for compress() in libz in order to find older versions
	of the library that will still work for hdf4.  Added a
	separate check for compress2() that hdf5 will use.

	Added checks for Posix.1g types like `int8_t'.  If not defined
	then H5private.h defines them.  Changed all `int8' etc. to
	`int8_t'.

	Calling H5*_term_interface() resets interface_initialize_g to
	FALSE so a subsequent call to H5open() (implied or explicit)
	reinitializes global variables properly.

./src/H5private.h
./src/H5Oefl.c
./src/H5S.c
	Changed MAX_SIZET, MAX_SSIZET, MAX_HSIZET, and MAX_HSSIZET to
	SIZET_MAX, SSIZET_MAX, HSIZET_MAX, and HSSIZE_MAX to they
	match the Posix.1 constants in <limits.h>.

./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5detect.c
	Added 36 more integer hardware conversion functions to the
	type conversion table for conversions to/from `long long' and
	`unsigned long long'.  The `long long' names will be changed
	shortly to make them portable to Win32.

	Changed H5T_init() to H5T_native_open() and added an
	H5T_native_close() to open and close the predefined native
	data types.

	Increased the initial size of the type conversion table from
	64 to 128 entries.

	Reordered the 90 new integer conversion functions so the names
	that are printed favor `int' over `short' or `long' when two
	of them are the same.

./test/dtypes.c
	Added hardware and software integer conversion tests for the
	56 functions I added recently but not the additional 36
	checked in this time.  That will come next.

	Call H5close() after each test so type conversion statistics
	are easier to follow.  Try this: $ HDF5_DEBUG=t ./dtypes

	Added more debugging output for when things go wrong.

./src/H5private.h
	Removed trailing carriage-returns inserted by broken operating
	system ;-)
