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++)

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.

7bff4eb559 [svn-r5904]
Purpose:
    Added 'ID to name' support
Description:

    There is a new API function H5Iget_name
    Most of the changes are on H5G.c , regarding the symbol table entry struct H5G_entry_t
    which has 2 new fields 'name' and 'old_name'

    A new private function was introduced H5G_ent_copy, that does a deep copy
    between 2 symbol table entries

    The test file is getname.c

Description:
    Changed the last HRETURN* statements in the FUNC_ENTER macros into HGOTO*
    macros, which reduces the size of the library binary in certain

d8397a6f42 [svn-r5842] Purpose:
Code cleanup

Description:
    Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with
    HRETURN macros to HGOTO_DONE macros.  This unifies the error return path
    from functions and reduces the size of the library by up to 10% on some
    platforms.

    Additionally, I improved a lot of the error cleanup code in many routines.

Platforms tested:
    FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial &
    parallel.

e69e970a1c [svn-r5471] Purpose:
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.

e87fc517b8 [svn-r4355] Purpose:
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.

Platforms tested:
    FreeBSD 4.4 (hawkwind)

Update
Description:
    Changed

        #include <hdf_file.h>

    construct to

        #include "hdf_file.h"

    so that the GNU compiler can more easily pick up the dependencies
    which it places in the .depend and Dependencies files. Also
    regenerated the Dependencies to go along with this.

ba28c64ba7 [svn-r2652] Purpose:
Maintainance & performance enhancements
Description:
    Re-arranged header files to protect private symbols better.

    Changed optimized regular hyperslab I/O to compute the offsets more
    efficiently from previous method of using matrix operations.

    Added sequential I/O operations at a more abstract level (at the same level
    as H5F_arr_read/write), to support the optimized hyperslab I/O.

Platforms tested:
    Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)

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.

./src/H5Tpkg.h
./test/h5test.h
	Removed __unused__ from forward function declarations.

./src/H5P.c
	Removed a comment about restrictions for the type conversion
	temporary buffers. Thanks to Quincey, the comment no longer
	applied.

./src/H5T.c
	Relaxed the H5Tpack() a little so it would pack compound data
	structures that had non-transient atomic members.

./tools/h5ls.c
	Added a `-g' (or `--group') flag that causes information to be
	printed about the specified group instead of the group's
	contents. (sort of like Unix's `ls -d'). The `-g' can be used
	in combination with `-r' to print information about the group
	and its contents.

	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/chunk.c
./test/flush1.c
./test/flush2.c
./test/iopipe.c
./test/overhead.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.

./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

	reinitializes global variables properly.

./src/H5private.h
./src/H5Oefl.c
./src/H5S.c
	Changed MAX_SIZET, MAX_SSIZET, MAX_HSIZET, and MAX_HSSIZET to

	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 ;-)

./src/H5HGprivate.h
	Added padding fields in symbol table entries, attribute
	messages, shared messages, and global heap objects to insure
	that things are aligned on 8-byte boundaries in the file, and
	thus in memory.  Otherwise some little endian machines
	complain (DEC Alpha) during encoding/decoding of file meta
	data.  I chose to add alignment to the file rather than
	rewriting the ENCODE/DECODE macros for the little endian case.

	Completely rewrote the section on attribute messages.

	More alignment stuff will follow.

./src/H5detect.c
	Fixed a typo `nd'->`dn'

./test/dtypes.c
	Commented out conversion tests to/from `long double' on

	Changed memory allocation functions so they fail instead of
	dumping core.  The `x' was removed from the name to remind us
	of that: H5MM_xmalloc() -> H5MM_malloc(), etc.

	H5MM_calloc() takes one argument like H5MM_malloc() instead of
	two like calloc() because we almost always called it with `1'
	for one of the arguments anyway.  The only difference between
	the two functions is that H5MM_calloc() returns memory which
	is initialized to zero.

./src/H5Gent.c
./src/H5Gprivate.h
	Removed H5G_ent_calloc() since it wasn't used.

./src/H5Fistore.c
	Fixed a bug found by Albert.  Thanks, Albert!  This fix
	combined with the changes to memory allocation prevent the
	library from failing an assertion if the application uses an
	unreasonable size for chunks (like Alberts 10000x10000x4).

./src/H5MF.c

./src/H5detect.c
	Updated to work with new internal H5T functions.  Fixed some
	data type memory leaks during error recovery.

./src/H5Dprivate.h
	Added H5D_typeof() similar to H5D_entof() that returns a
	pointer directly to the dataset's type.  This is used by
	H5Tcopy() when invoked on a dataset (see below).

./src/H5Epublic.h
	Fixed typos in H5E_BEGIN_TRY and H5E_END_TRY macros.

./src/H5F.c
	Closing a file with objects still open reports the file name
	in the warning message.  Removed unnecessary invalidation of
	shared data types.

./src/H5Gprivate.h
	Added `const' to some arguments.

./src/H5O.c
./src/H5Oprivate.h
./src/H5Oshared.c
	An object header message can now be a pointer to a message in
	some other object header.  The pointer is to the first message
	of the appropriate type in the other object header and hard
	link counts are maintained automatically to prevent dangling
	pointers.  The old global heap method of message sharing is
	also supported although nothing actually uses it.

	Changed the data type for the shared message info struct to

	methods struct for the set_share method.

./src/H5Odtype.c
	Added the ability to share data type messages by pointing to
	other object headers.

./src/H5T.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
	Added named data types and changed the functionality of some
	API functions as follows:

	* The term `read-only' means that a type handle cannot be
	  modified with functions like H5Tset_*() or H5Tinsert().

	* The term `immutable' means the same as `read-only' with the
	  added restriction that H5Tclose() cannot be called for the
	  type. A transient type is made immutable by calling
	  H5Tlock().

	* Handles to named types are always read-only.

	* Handles to predefined types are immutable.

	* A transient type can be converted to a named type by calling
	  H5Tcommit().  This function will fail if the type is already
	  named or is immutable.

	* The API function H5Tcommitted() returns an indication of
	  whether a data type has been commited (or is named).  If
	  H5Tcommitted() returns TRUE for a data type obtained by
	  calling H5Dget_type() on a dataset, then the dataset is
	  using a shared data type.

	* H5Topen() returns a handle to a named type.

	* H5Tcopy() always returns a handle to a modifiable transient
	  type even when invoked on a named type.  Also, when invoked
	  on a dataset it returns a modifiable transient type which is
	  a copy of the dataset's data type.

	* Using a named data type in the call to H5Dcreate() causes
	  the dataset object header to point to the named data type,
	  but using a transient type causes the type to be copied into
	  the dataset's object header.

	* The data type returned from H5Dget_type() is a named data
	  type or a read-only transient data type depending on whether
	  the dataset points to a named data type.   The old behavior,
	  to return a modifiable transient type, is accomplished by
	  overloading H5Tcopy() to operate on datasets (see above).

	* H5Tshare(), H5Tunshare(), and H5Tis_shared() have been
	  removed from the API.

	The following features were *not* implemented because they
	need more discussion:

	* A named data type can be opened by applying H5Topen() to a
	  dataset in which case the data type is the data type of the
	  dataset (or the data type to which the dataset points if the
	  dataset has a shared data type).

	* A named data type can have attributes like groups or
	  datasets.

	* The members of a compound data type can point to named data
	  types.

./src/h5ls.c
	Reports `Data type' for named data type objects in the file.

	Symbolic links are now supported.  The ./test/links program
	will create a `links.h5' file that demonstrates hard links,
	soft links, dangling links, and recursive links.  A symbolic
	link is a symbol table entity and doesn't have an object

./src/H5G.c
./src/H5Gpublic.h
./src/h5ls.c
	Implemented H5Gstat() and H5Gget_linkval() as documented by
	Quincey.  The `H5G_type_t type' field of `H5G_stat_t' was
	changed to `int type' because H5G_type_t was already used and
	the `type' data type should be open-ended.

./src/H5Ffamily.c
	Removed an incorrect diagnostic message.

./test/big.c
	Added read/write calls to test partial I/O to big contiguous
	datasets.  With no arguments it writes to a dataset and prints
	the list of points written which should be redirected to a
	file.  With an argument (the name of a file containing the
	stdout of a run with no arguments) values are read from the
	dataset.  One would typically say `big >x && big x'.

	Anything having to do with the size of a dataset now uses the

	at least as large as `size_t'.  This isn't fully tested yet,
	so hsize_t and hssize_t are defined as size_t and ssize_t in
	H5public.h.  Setting them to larger values will trip up gcc
	versions less than 2.8.1 on x86 platforms.

	Documented unused function formals with `__unused__' before

	Documented sharing of data types between datasets.

./src/H5G.c
./src/H5Gpublic.h
	Implemented H5Gmove(), H5Glink() and H5Gunlink() for hard
	links.  Still have soft links to do.

55ac27633b [svn-r188] Changed hbool_t from an enum to 'int' and removed BTRUE/BFALSE/BFAIL from code.
Changed interface to the H5P..hyperslab functions to 'int' instead of 'size_t'.
Cleaned up lots of warnings on IRIX 6.2 platform.  Minor other tweaks to get
to a mostly clean build on the SGI.  It still whines about 'long long' being
non-standard and some "pointless comparison of unsigned with 0" but those
aren't big problems.

        closed.

./src/H5C.o
./src/H5Cpublic.h
./test/dsets.c
./test/tfile.c
        Split H5Cget_prop() and H5Cset_prop() into functions for each

1d17defdfc [svn-r150] Changes since 19971219
----------------------

./src/H5private.h
        Changed HDF5_MAJOR_VERSION to 5

./src/H5Aprivate.h
./src/H5Apublic.h
        Added group atoms.

./src/H5D.c
./src/H5P.c
./test/istore.c
./test/tohdr.c
./test/tstab.c
        Updated for symbol table interface changes.

./src/H5F.c

./src/H5Oprivate.h
        Access to object headers is always done through a symbol table
        entry instead of a file address.  Added stubs for opening and
        closing object headers to be used when deletion is implemented.

faca6fbaa8 [svn-r145] ./src/H5Osdtyp.c -> H5Odtype.c
./src/H5Osdim.c		-> H5Osdspace.c
./src/Makefile.in
	Changed the names of these files to better reflect what they
	actually do.

./src/H5.c
./src/H5AC.c

./src/H5T.c
./src/H5detect.c
./src/H5private.h
	Added an argument to the HRETURN_ERROR(), HGOTO_ERROR(), and
	HERROR() macros which is a string error message.  This allows
	us to give extra information which can't be represented by the
	major and minor error numbers.  This information was
	previously in comments just before or after the macro call.
	The string isn't currently used, but I'm planning to change
	the test files so they print an error trace when something
	fails.  This should make debugging a little faster since it's
	often obvious what's wrong if we could just see the error
	stack without even having to start a debugger.

082dd8cda9 [svn-r139] ./src/*.[ch]
Removed the interface initialization argument from
	FUNC_ENTER() and made it a locally-defined preprocessor
	symbol, INTERFACE_INIT.

	Changed `offset' to `address' and `length' to `size' in
	documentation so it's more consistent.  `Offset' still appears
	occassionally when it refers to a byte offset within some
	other data structure.

	Moved interface termination function prototypes from public
	header files to .c files and made them static.

./src/H5.c
./src/H5public.h
	Added H5init() because it's possible that the predefined data
	types are not initialized.  This happens only if the first
	call to the hdf5 library passes a predefined data type symbol
	as an argument.  There should be some way to fix this...

./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
	The free_func returns SUCCEED or FAIL, although the return
	value is ignored by H5A.  This is so we can use the various
	H5*_close() functions to free things.

	H5Ainc_ref() and H5Adec_ref() are no longer public.  Many of
	the other atom functions should also be made private, but I'll
	save that for later...

	Added additional template groups called H5_TEMPLATE_0 through
	H5_TEMPLATE_7 that are used by the various template
	subclasses.

	Increased the number of bits used for atom groups to prevent
	negative atoms.

./src/H5AC.c
./src/H5ACprivate.h
	Changed H5AC_new() to H5AC_create() to make names more consistent.

./src/H5B.c
./src/H5Bprivate.h
	Changed H5B_new() to H5B_create() to make names more consistent.

./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
	Now supports multiple subclasses of templates, although it's
	done with big switch statements.  The default values for
	templates are defined in the source file to which that
	template belongs.  This got rid of lots of needless
	preprocessor constants.

	Added H5Ccreate() to create a new template.  Changed
	H5C_release() to H5Cclose() to make the naming more
	consistent.

./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpublic.h
	Enhanced to use the new dataset interface, and uses the enhanced
	data type and data space interfaces, which haven't been
	completely implemented.  The dataset interface doesn't handle
	non-contiguous storage, compression, or data type and space
	conversions yet.

./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
	Removed H5Fflush() since just calls H5F_flush(), which doesn't
	do what the user would probably think it does, namely, flush
	everything.  It only flushes those things sitting in the H5AC
	cache and the boot block.

	Changed the `file_create_parms' field of H5F_low_t to just
	`create_parms' since the `file' part is obvious.

./src/H5Fistore.c
	Added some support for external files.  Mostly just in the
	file format and not supported much by the library yet. I need
	to finish some dataset functions first.

	Changed H5F_istore_new() to H5F_istore_create() to make names
	more uniform across packages.

./src/H5Flow.c
	Flushing a file causes the file to be physically extended to
	the logical eof.  This prevents H5F_open() from thinking a
	file has been truncated.  Most of the time the file will
	already be that large, and when it isn't Unix will often just
	allocate the final block anyway.

./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gstab.c
	Removed H5G_basename()

	Removed (temporarily) data type information from symbol table
	entries and renamed H5G_CACHED_SDATA to H5G_CACHED_SDSPACE to
	reflect that it's a simple data space and has nothing to do
	with raw data.

	Changed H5G_node_new() to H5G_node_create() and H5G_stab_new()
	to H5G_stab_create() to make names more uniform across
	packages.

	Fixed an undefined address bug that happens when H5G_node_debug()
	program doesn't pass enough info to H5G_node_load().

./src/H5H.c
./src/H5Hprivate.h
	Changed H5H_new() to H5H_create() to make the names more
	uniform across packages.

./src/H5M.c
./src/H5Mprivate.h
./src/H5Mpublic.h
	Nulled all the create functions.  Most of the other callbacks
	are to public functions.  Removed H5Mcreate().

	Changed hobjtype_t to group_t since it has to be the same
	thing anyway.

./src/H5O.c
./src/H5Oprivate.h
./src/H5Osdim.c
./src/H5Osdtyp.c
	Changed H5O_SIM_DIM to H5O_SDSPACE (simple data space) since
	`simple data space' is its official name, not `simple
	dimensions'.  Will eventually add H5O_CDSPACE for comples data
	spaces. Changed _sim_dim_ to _dspace_.

	Replaced H5O_SIM_DTYPE and the compound data type messages
	with a single H5O_DTYPE message. Changed _sim_dtype_ to _dtype_.

	Changed H5O_STD_STORE to H5O_CSTORE (contiguous storage) since
	contiguous storage is not necessarily standard.  Changed
	_std_store_ to _cstore_ in H5Ocstore.c

	Added the H5O_EFL (external file list) message.

	Changed H5O_new() to H5O_create() to make names more uniform
	across packages.

./src/H5Oefl.c		NEW
	External file list message for specifying which non-hdf5 files
	contain raw data for a dataset.

./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
	Renamed and moved data structures to make the names conform to
	our naming scheme.

./src/H5T.c
./src/H5Tprivate.h
./src/H5Tpublic.h
./src/H5Tpkg.h		NEW
	Data structures redesigned to be more flexible.  The interface
	was redesigned to make it more regular and to make some names
	more uniform across packages.

./src/H5detect.c
	Output was changed to produce a file that conforms to the hdf5
	coding standard.

./src/Makefile.in
	Generates H5Tinit.c by running H5detect.

./src/debug.c
	Moved command argument processing.

cdeeb5553a [svn-r136] ./MANIFEST
./src/Makefile.in
	Added H5Ffamily.c and H5Fsplit.c

./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
	Added `const' to sublass arguments.

./src/H5F.c
./src/H5Flow.c
./src/H5Fsec2.c
	Make sure file buffers get flushed during a call to
	H5Fflush().  Check for overflow in address encoding and decoding.

./src/H5Ffam.c
./src/H5Fprivate.c
./test/istore.c
	Implementation of file families so 32-bit machines can access
	64-bit files.

./src/H5Oprivate.h
	Removed H5O_NO_ADDR constant.

./config/freebsd2.2.1
./config/linux
	Added -DH5G_DEBUG and -DH5F_DEBUG to the list of debugging flags.

./html/H5.format.html
	Changed some <offset>-sized things to <length>-sized things.

./src/H5AC.c
./src/H5ACprivate.h

./src/debug.c
./test/istore.c
./test/theap.c
./test/tohdr.c
./test/tstab.c
	Lots of changes caused by generalizing addresses.  The haddr_t
	is now a struct, so you can no longer perform arithmetic on
	it. But since it's small, simple, and often used, storage is
	allocated like with an integer.  But we always pass them
	around by reference.  That is, when using an address in
	another struct, allocate space:

		struct my_struct {
		   char *name;
		   haddr_t address;
                } x;

	But when passing it to a function, pass by reference:

		H5F_addr_print (stderr, &(x.address));

	Addresses should be initialized with

		H5F_addr_undef (&(x.address));

	Functions for operating on addresses are in H5Flow.c and begin
	with H5F_addr_...  Functions never return haddr_t or haddr_t*;
	they always pass them through arguments instead. A function
	that returns an address through an argument does so with its
	last argument and it is marked with `/*out*/'.  Calls to such
	functions also mark output-only arguments with `/*out*/'

./src/H5Fsplit.c       (new)
	A two-member family where all meta data goes in the first
	member and all raw data goes in the second member.

./src/H5B.c

./src/H5Gnode.c
./src/H5H.c
./src/H5MF.c
./src/H5MFprivate.h
./src/H5O.c
	Differentiate between meta data storage and raw data
	storage. Provide a mechanism so that the file driver can
	extend the file to allocate more memory.

./src/H5E.c
./src/H5Epublic.c
	Added the error H5E_TRUNCATED to be reported when the file is
	shorter than the length recorded in the boot block.

./src/H5F.c
	Added H5F_locate_signature() so we only do it in one place
	now.

./INSTALL
./INSTALL_MAINT
	Just a couple clarifications.

./html/ExternalFiles.html
./html/storage.html
	Documents how external files work.

./test/hyperslab.c
./test/istore.c
	Fixed printf's on 64-bit machines.

./test/istore.c
	Added ifdef's to test the split file driver.

56ad55117a [svn-r129] Changes since 19970916
----------------------

./config/depend.in
	Fixed backslashes in sed script because the H5Gnode.c
	dependency info was disappearing.  You'll have to rerun
	config.status to rebuild the Makefiles unless you use gnu
	make.

./config/conclude.in
	Also removes emacs backup files, TAGS, and svf backup files.

./config/linux
	Grouped gcc flags and added provisions for debugging vs. production.

./html/H5.format.html
	Updated messages 0x0008, 0x0009, and 0x000A.

./html/storage.html
	Documentation describing storage schemes.

./src/H5G.c
./src/H5Gnode.c
./src/H5Gprivate.h
./src/H5H.c
./src/H5O.c
	Removed `const' from some variables because H5G_node_found() wanted
	to modify it's udata argument. Removing const there caused it
	to cascade to these other locations.

./src/H5AC.c
./src/H5ACprivate.h
./src/H5B.c
./src/H5Gnode.c
./src/H5Gstab.c
./src/H5H.c

	argument to the H5AC_find() macro.

./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
	Extra argument passed to the sizeof_rkey() method.

./src/H5Gnode.c
./src/H5Gprivate.h
	Beginning to add H5G_open/close and related bug fixes.

./src/H5Oprivate.h
./src/H5Oistore.c (new)
	Added the H5O_ISTORE messsage (0x0008) for indexed storage of
	objects.

./src/H5private.h
	Added extra braces around both sides of the FUNC_ENTER() and
	FUNC_LEAVE() macros so FUNC_ENTER() can appear before
	declarations or after executable statements the second case is
	used by H5G_namei() to initialize output arguments to sane
	values before FUNC_ENTER() might return failure.

		int f ()
		{
		   int decl1;
		   printf ("This happens before FUNC_ENTER()\n");
		   FUNC_ENTER (...);
		   int another_declaration;

./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
	Extra arguments for key encoding and decoding.

./src/H5E.c
./src/H5Epublic.h
./src/H5Fistore.c
./src/H5Oistore.c
./src/H5Oprivate.h
	Indexed, chunked, sparse storage (not ready for general consumption
	yet).

./src/H5V.c		(new)
./src/H5Vprivate.h	(new)
./test/hyperslab.c	(new)
	Vector, array, and hyperslab functions.

./src/H5B.c

./src/H5Fistore.c
./src/H5Gnode.c
./src/H5V.c
./src/H5Vprivate.h
./test/hyperslab.c
	Added functionality for indexed storage.

./src/H5F.c
	Fixed problems with seek optimizing.  Recommend we disable it
	until we can implement it in the file/address class since all
	of HDF5 must be aware of it.

./src/H5O.c
	Fixed comeent speling erorr :-)

./MANIFEST
	Added new files.

./config/conclude.in
	Added the word `Testing' to the test cases.  So if a test
	program is called hyperslab then the make output will contain
	the line `Testing hyperslab'.

./config/linux
	The default file I/O library is Posix section 2 on my linux
	machine so I can do some I/O performance testing.

./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
	Added ability to set size of indexed-storage B-tree.

./src/H5D.c
