f3e445cfcb [svn-r7469] Purpose:
Code cleanup, etc.

Description:
    Generalize Ray's datatype fixes to handle packing compound datatypes which
are the base type of an array or variable-length type, etc.

    Also track "packedness" of a compound datatype from it's creation, instead
of only setting the 'packed' flag after the datatype was explicitly packed.

    Updated docs to reflect that a compound datatype is allowed to grow (but
not shrink).

Platforms tested:
    FreeBSD 4.9 (sleipnir)

04137b3a16 [svn-r7435] Purpose:
Bug Fix and code cleanup

Description:
    Correct error in H5T_detect_class that was causing nested compound datatypes
with to not detect the datatype class of fields correctly, which caused errors
with fill-values, variable-length datatypes and chunks later on.

    Return the rank of the array datatype from H5Tget_array_dims(), like
H5Sget_dims().

    Lots of cleanups to datatype code, to make the handling of arrays, compound
types, variable-length strings and sequences and enumerated types more
consistent and robust.

Code cleanup.

Description:
    Move many package or internal function prototypes and macro definitions
into tighter scope according to their current use.
    Added more comments where appropriate.
    Eliminate ancient, unused functions.

7d63d5e3ff [svn-r6395] Purpose:
Code cleanup.

Description:
    Break up the ~9350 line H5T.c module into smaller pieces, which contain
    code for a particular feature or support for a datatype class.

    This should make the "main" H5T code (still in H5T.c) easier to support,
    as well as removing some of the "minor" routines from the user applications
    which don't use them (my rough estimates show about 4% reduction (~30K on
    a FreeBSD machine) in optimized, staticly-linked binaries for very simple
    programs)

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.

dba8c269a5 [svn-r4863] ./hdf5-devel/src/H5Tpkg.h
More optimizing for byte order conversion. Mostly just making code
easier to follow by simplifying Duff's device coding of the loops.

I also split the conversion function into two functions with different
names so output from H5T debugging indicates whether the optimized or
unoptimized case was invoked.

Purpose:
    Modify H5Fclose behavior
Description:
    The HDF5 actual file close behaves in several ways in terms of if there
    are still objects(dataset, group, datatype) opened in file.
Solution:
    Added a new file access property, file close degree.  It has four values,
	H5F_CLOSE_DEFAULT
	H5F_CLOSE_WEAK
	H5F_CLOSE_SEMI
	H5F_CLOSE_STRONG
    The way a file is closed is decided by these values.

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.

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.

    Added array datatype to library.  See documentation at:
        http://hdf.ncsa.uiuc.edu/HDF5/planning/DP/ArrayType.html
    for complete details on the impact to the library.
Solution:
    Changes to the base library include removing the ability of compound
    datatype fields to be an array (they can use an array type for the field,
    to duplicate the functionality) and adding in the new array datatype
    everywhere appropriate. (I hope :-)

** src/H5Tconv.c
** src/H5Tpkg.h
** src/H5Tpublic.h
	The H5T_conv_struct_opt() function had a design flaw -- it
	didn't keep information about the stride to use to step
	through the temporary/background-value buffer and thus nested
	invocations would clobber each other's temp buffers.  This was
	fixed by splitting the `stride' argument into `buf_stride' and
	`bkg_stride' arguments for all the conversion functions. THIS
	IS AN API CHANGE, but users will get a compiler warning when
	they pass their conversion function pointer to H5Tregister().

** src/H5T.c
** src/H5Tprivate.h
	Added a bkg_stride argument to the H5T_convert() definition in
	order to fix a bug related to the optimized compound datatype
	conversion function.

** src/H5T.c
** src/H5A.c
** src/H5D.c
** src/H5Ofill.c
** src/H5P.c
	Added bkg_stride=0 argument to the H5T_convert() calls.

** test/dtypes.c
	Added a test for the H5T_conv_struct_opt() bug fixed above.

** src/H5FL.c
	The H5FL_term() function should return non-zero even when it
	couldn't free all the free lists do to their being used by
	some other package.  When that other package terminates it
	will return non-zero, causing H5FL_term() to be called
	again. This fixes some of the `infinite loop closing library'
	messages.

** tools/pdb2hdf
	Uses print_version() instead of doing that itself.

** src/H5Ppublic.h
	Renamed H5Pget_gc_reference() declaration to make it match the
	definition.

** src/H5FDlog.c
	Added API tracing macros.

	Removed `const' qualifier from a `char*' member of a struct
	which was allocated on the heap.

** src/H5TB.c
	Added curly braces to a couple deeply-nested `if' statements
	to make them clearer and to shut up the increadibly stupid and
	just plain incorrect gcc warning about ambiguous `else'.

** test/titerate.c
	Removed incomplete initialization in favor of memset() for one
	auto variable to stop compiler warnings.

** tools/Depencencies
	Regenerated to remove references to h5dumputil.c

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.

	access and data transfer properties by object ID instead of

	Changed H5D_transfer_t to H5FD_mpio_xfer_t since the

	Changed the logic that controls whether the boot block is

	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

	the virtual file layer.

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

	Moved file driver-specific code into the various file driver

	file access and data transfer properties.

650e29cff6 [svn-r1418] Modified H5Tconvert to require a dataset transfer property list ID as the
final parameter (so that VL datatypes have a way to pass in the custom memory
allocation routines).
    Fixed a conversion bug when VL fields were part of a compound datatype that
was causing the no-op conversion routine to be used instead of the vlen routine.
    Added the H5Pset_vlen_mem_manager and H5Pget_vlen_mem_manager routines to
allow users to provide their own custom memory allocation routines for VL data
read in from the file and reclaimed with H5Dvlen_reclaim.
    Finished coding on H5Dvlen_reclaim so it works now.

8baa675250 [svn-r1362]
Changes since 19990616
----------------------

./src/H5T.c
./src/H5Tconv.c
	All conversion functions take an extra argument called
	`stride' which is the number of bytes to advance the source
	and destination pointers after each element is converted. If
	the value is zero then the old behavior is preserved (source
	and destination values are packed). This feature was necessary
	to implement the compound datatype conversion optimizations
	and it causes a minor change to the API (application-defined
	type conversion functions take an extra size_t stride
	argument).

./src/H5Tconv.c
	An additional compound data type conversion function was added
	which is applied unless the destination type is larger than
	the source type. I'm measuring significant performance
	increases for certain operations:

	    Test Name    Struct-Conv    Noop-Conv
			 New(Old) MB/s  New(Old) MB/s
	    ----------   -------------  -------------
	    Reordering   2.062(0.3936)  54087(0.9047)
	    Subsetting   2.901(0.6581)  40192(1.1100)
	    Shrinking    1.976(0.3925)  33628(1.1500)
	    ----------   -------------  -------------

./test/dtypes.c
	Added various compound datatype conversion tests.

	Fixed return values from functions.

./src/H5T.c
	Conversion timers are updated only if H5T debugging is turned
	on a runtime (in addition to compile time). This allows the
	data type layer to be compiled with debugging support without
	having to pay a big runtime penalty if the debugging isn't
	actually used.

./src/H5A.c
./src/H5D.c
./src/H5Ofill.c
./src/H5P.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
	Added the stride argument to the H5T_convert() calls. The
	stride is always zero, which means that the source and
	destination data values are packed.

./configure.in
./configure			[REGENERATED]
	If API tracing is turned off then libhdf5.settings will say
	`no' instead of nothing.

./test/flush1.c
./test/flush2.c
	Added better error messages in a couple places.

	Fixed a bug with glibc2 on linux systems where `stdout' is an
	extern and can't be used to initialize static data.

./src/H5T.c
./src/H5Tpkg.h
./src/H5Tpublic.h
./src/H5detect.c
	Removed the `_T' from the new C9x types I just added so the
	names are consistent with existing types. Besides, the fact
	that something is a datatype is obvious because it starts with
	H5T_NATIVE_.

./tools/h5ls.c
	Added the new C9x data types. H5ls prints one of these types
	only if it doesn't match one of the builtin C types.

	Prints the OID for shared data types.

	Fixed a formatting bug with symbolic links which was
	introduced a few changes ago.

	The commandline has been changed so that objects from multiple
	files can be listed with a single command. Instead of
	specifying a file name and an optional list of objects, each
	thing to print is a file name and object concatenated. H5ls
	figures out how to devide the name into a file name and object
	name even when the file name part doesn't correspond to an
	actual Unix file.

	   Old syntax: h5ls [OPTIONS] FILE [OBJECTS]
	   New syntax: h5ls [OPTIONS] FILE[/OBJECT] [FILE[/OBJECT]]...

	   Example ({X,Y} is expanded by the shell)

	   Old command: h5ls -d ../test/x.data dir1 dir2
	   New command: h5ls -d ../test/x.data/{dir1,dir2}

	The filename is printed as part of the object name when full
	names are requested (--full or --recursive). If people really
	don't like this they can undefine a constant at the top of
	h5ls.

	Errors from the hdf5 library are turned off.

	Commandline switches of the form `--width 80' are accepted in
	addition to `--width=80'. This is more symmetric with
	single-letter switches that take two forms: `-w 80' and
	`-w80'.

./src/H5D.c
	Added tracing instrumentation for H5Dvlen_reclaim().

./src/H5private.h
	Added casts to int for the isalpha() et al macros to shut up
	solaris warnings about char subscripts.

Remove changes from CVS

./bin/release

	sometimes useful when you need to make a quick snapshot but
	the MANIFEST file is not quite up to date.

./src/H5D.c
	Removed warnings for unused variables

./src/H5Fprivate.h
	Removed the WIN32 definition for `uint' and changed the data

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

./tools/h5tools.c
	Strings are not converted to null-padding before being
	printed; they are printed with whatever byte values appear in
	the file.

./tools/h5ls.c
	Now able to display attribute data type and data.

	Added a `-f' or `--full' switch which causes the full name of
	each object to be displayed instead of just the base name.

	Added a `-r' or `--recursive' switch that recursively prints
	the contents of groups, avoiding cycles.

	More bulletproofing for non-printable characters in things
	like object names, attribute names, and comment strings. We
	don't want listing a file to send termal escape sequences
	because it's sometimes possible to execute commands that way.

	Since h5ls doesn't usually use quotes around object names we
	must sometimes escape space characters.

	External files are listed in a table to make the output less
	confusing.

./tools/h5tools.c
./tools/h5tools.h
	Changed h5dump() to h5dump_dset() and added h5dump_mem(). Also
	make h5dump_fixtype() public.

        H5T_enum_insert().

./src/H5RA.c
./src/H5Shyper.c
        Added casts to size_t for the third argument of memcpy() to
        shut up a warning message from insure++.

./src/H5T.c
        Changed "can't" to "unable to" in some error messages to be
        more consistent.

./src/H5detect.c
        If fork() or waitpid() are unavailable then we assume no
        alignment constraints. Hopefully this is the case only on NT
        and Intel CPU's don't have alignment constraints.

./src/H5public.h
        Include <limits.h> because the H5T_NATIVE_CHAR macro needs the
        definition for CHAR_MIN.

09aaf83332 [svn-r971] Changes since 19981214
----------------------

./INSTALL
	Added warning that enabling debugging code can adversely
	affect performance even when the debugging isn't turned on at
	run-time. Performance testing shows that under certain
	circumstances (like data type conversions of compound types)
	the H5_timer functions, although only a few lines each,
	contribute a fairly large percent to the execution time.

./src/H5T.c
./src/H5Tpkg.h
./src/H5Tpublic.h
	Improved the H5Tunregister() function to make unregistering
	more flexible.  It takes the same arguments as H5Tregister()
	but also accepts wild cards.  All conversion functions that
	match the H5Tunregister() search criteria are removed from the
	global type conversion table.

	The H5Tregister_hard() and H5Tregister_soft() were combined
	into a single function called H5Tregister() which is the
	counterpart to H5Tunregister(). A new `persistence' argument
	was added to differentiate between the two types of conversion
	functions.

	The application is allowed to register a hard conversion
	function for the no-op conversion path although the library
	isn't obligated to call it (it usually does). This is mostly
	for completeness, but the application might use it to help
	determine if the raw data pipeline was able to use the
	optimized path for the case when no type conversion is
	necessary. The library doesn't allow this path to be
	unregistered although the application can redefine it as often
	as it likes.

	Fixed the type conversion tables in preparation for MT-safety
	and to fix previosly-known design bugs wrt. unregistering
	conversion functions or changing the C function associated
	with a conversion path. The MT-safety stuff is documented in a
	separate white paper.

	Increased the conversion function debugging name from 9
	characters to 31 characters so the output can be more
	descriptive.

	Moved conversion path statistics from the H5T_cdata_t member
	into the conversion path itself.  This makes H5T_cdata_t
	contain only application-visible data structures.

./src/H5A.c
./src/H5D.c
./src/H5Ofill.c
./src/H5P.c
./src/H5T.c
	Improved the way type conversion functions are called so the
	caller doesn't have to check for data type debugging and
	increment type conversion timers and statistics.

	Changed check for no-op conversion since it is now
	application-definable and there may even be more than one
	definition at a time in a multi-threaded application (one
	thread might be using the no-op conversion path when some
	other thread changes its definition -- the first thread still
	sees the original defintion until it's done with the
	operation).

./doc/html/Datatypes.html
	Updated the user guide to reflect the changes to data type
	conversion registration functions.

./bin/trace
./src/H5.c
	Added tracing support for the new H5T_pers_t data type.

./test/dtypes.c
	Added printf to display alignment value if non-aligned data
	types are being tested.

./test/h5test.c
	Modified the H5Tunregister() calls to use the new
	arguments. All 94 of those calls can be replaced by a single
	call to the new H5Tunregister() function.

./src/H5.c
	Added HAVE_GETTIMEOFDAY around an auto variable and
	initialized the elapsed time to zero when gettimeofday() is
	not available.

./src/H5F.c
./src/H5Fprivate.h
./src/H5P.c
	Added an H5*_init() functions which do the same thing as
	H5*_init_interface() but can be called from other packages and
	don't do anything if the interface is already initialized.
	This fixes a couple memory leaks in applications that
	repeatedly close and open the library with H5close().

./src/H5Tconv.c
	Optimized some data alignment code in the hardware conversion
	functions.

	Hardware conversions accumulate statistics about source and
	destination data alignment and print that information when the
	conversion function is unregistered (usually when the
	application exits) if data type debugging is compiled into the
	library and enabled at run-time.

	The conversion caching was cleaned up for the compound data
	type conversion function. It now caches conversion paths in a
	manner that will be MT-safe and is much simpler than the old
	method. Also cleaned up some array index maps.

./src/H5detect.c
	Fixd mispelling of alingemnt.

./src/H5private.h
	Changed `TRUE' to `1' in assignment to interface_initialize_g
	in FUNC_ENTER macro definition.

./tools/testh5dump.sh
	Completely rewritten to make it shorter, better documented,
	and conforming to most of the other test outputs.

	The comparison of the actual output with the expected output
	is insensitive to differences in white space.  The test now
	passes for the first time on Linux where the output width
	wasn't as expected but the output was otherwise correct.

./src/H5detect.c
./src/H5T.c

	Detects alignment constraints. In order for this to work the
	operating system must not correct unaligned data (for
	instance, on the DEC Alpha one might need to say `uac p
	sigbus' before running H5detect).

./src/H5private.h
	Includes <signal.h> because it's needed by H5detect.c to
	detect alignment constraints.

./src/H5Tconv.c
	Added extra checks to all hardware conversion functions so
	they align data when necessary before the conversion.  This
	slows down the conversions somewhat but they're still much
	faster than the software conversions.

./test/dtypes.c
	By setting a constant at the top of the source you can test
	conversions where the data is aligned on various byte
	boundaries.

	By setting a constant at the top of the source you can

	Added a new H5T_NATIVE_CHAR type which has the same range,
	representation, and behavior as either H5T_NATIVE_SCHAR or
	H5T_NATIVE_UCHAR depending on the compiler and its
	command-line switches for the application source file which
	references H5T_NATIVE_CHAR. If source files are compiled with
	different switches then each source file will resolve
	H5T_NATIVE_CHAR appropriately so it matches the C type `char'
	in that source file.

	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 ;-)

841e168a04 [svn-r914] Changes since 19981113
----------------------

./config/conclude.in
./test/Makefile.in
./tools/Makefile.in
	The Makefile $TESTS variable has finally been split into
	$TEST_PROGS and $TEST_SCRIPTS with the latter being the names
	of shell scripts that need to be run with `/bin/sh'.  Now we
	don't have to copy each shell script before we run it. NOTE:
	THIS CHANGE DOES NOT AFFECT THE PABLO MAKEFILE SINCE THAT FILE
	IS A COPY OF A PREVIOUSLY GENERATED MAKEFILE.

./src/Makefile.in
	Added H5Snone.c to the source list.

./src/H5G.c
	Plugged a memory leak by emptying the object type "isa" table
	when the library is closed.

./src/H5Tconv.c
./src/H5Tpkg.h
	Added 48 new type functions to take advantage of hardware for
	integer type conversions.  These functions are not registered
	in the conversion table yet because I haven't fully tested
	them.

./src/H5Tpkg.h
	Removed __unused__ qualifiers from prototypes.

7dcbae97f2 [svn-r800] Made a "htri_t" as a return value from "boolean" functions returning
TRUE/FALSE/FAIL, hbool_t is now strictly for true boolean values.

	Changed the values of the H5T_str_t type in order to make a
	distinction between C's null terminated strings and strings
	which are not null terminated.

	The string character set and padding method are saved to the
	hdf5 file instead of using defaults.

	Added conversion function from one fixed-length string type
	to another.

./test/chunk.c
	Fixed to work with new filter API

6a1bea937d [svn-r469] Changes since 19980707
----------------------

./bin/trace
./src/H5.c
	Added tracing support for H5S_seloper_t and H5S_class_t.

./src/H5Sselect.c
./src/H5S.c
	Added tracing statements that weren't inserted previously
	because of formatting problems.

./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
./test/cmpd_dset.c
	Added H5Tinsert_array() for inserting an array member into a
	compound data type.  Added support to the struct conversion
	function for member arrays.  The index permutation is not
	supported yet in the conversion (source and destination must
	have the same permutations).

	Output-only arguments have their addresses printed during
	tracing and added symbolic output for the H5F_driver_t
	arguments.  That's another reason that we should be careful to
	add `/*out*/' after arguments that are output-only and
	`/*in,out*/' after arguments that are used for both input and
	output values.

	No internal function calls H5Pget_class() anymore.

./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tpublic.h
	Added H5Tget_overflow() and H5Tset_overflow() so the
	application can query or set a function that will be called
	whenever an overflow occurs.  Implemented as documented in
	previous e-mail except the overflow handler gets two buffers:
	one that contains the source value and one to receive the
	optional destination value.

./test/dtypes.c
	Tests overflow handler.

./src/H5.c
	We have to declare fdopen() because I'm getting errors when
	compiling on Irix64 even though we include <stdio.h> as
	documented in the fdopen() man page.

1b3a1f8014 [svn-r437] Changes since 19980612
----------------------

./src/H5Tbit.c
./src/H5Tpkg.h
	Fixed a bug in H5T_bit_copy(). Added H5T_bit_get_d() and
	H5T_bit_set_d() which treat portions of a bit vector as an
	unsigned integer. Added H5T_bit_inc() that increments part of
	a bit vector and returns an indication of overflow.

./src/H5Tconv.c
./src/H5Tpkg.h
./test/dtypes.c
	Added a slow general floating point conversion which works so
	far on Intel, MIPS, and DEC but the test is turned off because
	a cast from double to float will cause a SIGFPE on some
	systems if an overflow occurs.

	Added fast hardware conversions between native floating point
	types.  This function is also subject to the SIGFPE problem.

./src/H5detect.c
	Removed the exponent bias adjustment when the significand
	isn't normalized.  This is now handled in the conversion
	functions instead.

./src/H5T.c
	Register new conversion functions.

	Plugged a memory leak in the library termination code.

./RELEASE
	Added a list of major changes since the first alpha.

./src/H5MM.c
	Added PABLO_MASK to this file.

./test/chunk.c
	Removed a warning about memcpy().
