./MANIFEST
./configure.in
	Added more checking for `make' features.

./Makefile.in
./doc/Makefile.in
./doc/html/Makefile.in
./doc/html/Tutor/Makefile.in
./examples/Makefile.in
./pablo/Makefile.in
./src/Makefile.in
./test/Makefile.in
./testpar/Makefile.in
./tools/Makefile.in
./config/commence.in
./config/conclude.in
./config/depend.in		[REMOVED]
./config/depend1.in		[NEW]
./config/depend2.in		[NEW]
./config/depend3.in		[NEW]
./config/depend4.in		[NEW]
./config/dependN.in		[NEW]
	The directory search stuff was moved into commence.in, thereby
	shortening the Makefile.in prologues.

./doc/html/Dependencies		[NEW]
./doc/html/Tutor/Dependencies	[NEW]
./examples/Dependencies		[NEW]
./src/Dependencies		[NEW]
./test/Dependencies		[NEW]
./testpar/Dependencies		[NEW]
./tools/Dependencies		[NEW]
	The `.distdep' files were all renamed to `Dependencies' to make them
	more obvious. They are required (but may be empty) in every directory
	that has a Makefile.in that ends with @CONCLUDE@ (you'll get an
	obvious error from make if you forgot to create one).

./bin/trace
./src/H5.c
	Added H5E_major_t and H5E_minor_t although tracing only prints the
	integer value.

./src/H5E.c
./src/H5Epublic.h
	Added tracing information.

./src/H5FDcore.c
./src/H5FDfamily.c
./src/H5FDgass.c
./src/H5FDmpio.c
./src/H5FDsec2.c
./src/H5FDstdio.c
	Fixed places where FUNC_LEAVE() evaluated it's argument more than
	once.

	Added tracing information.

	Wrapped long lines.

./config/gnu-flags
	Fixed a syntax error when we don't have a gnu compiler.



Changes since 19991007
----------------------

./configure.in
./src/H5config.h.in	[REGENERATED]
	The /usr/ncsa/{include,lib} directories are only added if they
	actually exist. This fixes a warning on some systems.

	Checks for the <pdb.h> header file and also for either the PDB or Silo 
	library, and if found prepares to compile the pdb2hdf program.

./config/distdep
	Relative path names for include files are changed to base names since
	the makefile contains the logic for searching and since it's likely
	that building the .distdep files happed from a location other than
	where they would be used in the file system.

./config/conclude.in
	Fixed shell errors when `for' loops iterate over nothing for the
	`uninstall' target.

./src/H5D.c
./src/H5Oefl.c
	File names for the external files are added to the heap when the
	dataset is created instead of when the object header is written. This
	fixes a rare infinite recursion bug.

./src/H5FD.c
./src/H5FDpublic.h
	Optimization to the free list causes H5FD_alloc() usage to go from >10 
	seconds to <0.4 second for one example (converting a 30MB equation of
	state file from PDB to HDF5 format). The optimization is to simply
	keep track of the largest item in the free list and not search the
	free list when the largest item is not big enough to satisfy the
	request.

./src/H5FDcore.c
./src/H5FDcore.h
./test/h5test.c
	If the `backing_store' property is true then a flush causes the entire 
	contents of memory to be written to the specified file. This is  in
	preparation for the ASCI/red optimizations and is currently tested by
	the pdb2hdf `--cached' switch.

./src/H5Odtypes.c
	Wrapped three long lines.

./tools/Makefile.in
./tools/pdb2hdf.c		[NEW]
	A PDB-to-HDF5 translator. It only translates meta data -- the
	resulting HDF5 points into the PDB file for the raw data.

Changes since 19991007
----------------------

./src/H5FDcore.c
	Includes private headers instead of public in order to use the
	`UNUSED' macro.

./src/H5FDpublic.h
	Includes H5public.h just in case.

./src/H5P.c
	Removed two unused variables in H5P_copy()

./src/H5FDgass.h
	Fixed a C++ comment after a `#endif'

./src/Makefile.in
	The H5FDgass.h file is public and must be installed in order for
	applications to be able to use HDF5.

./tools/h5tools.c
	Removed an unused variable.

./tools/h5ls.c
	Fixed an error message when the file cannot be opened.

./src/Makefile.in
	H5FDgass.h is a public header file that needs to be installed.

Changes since 19990915
----------------------

./src/H5public.h
	We undefine a bunch of things that could get redefined in the config
	file because some customers have applications that include headers
	from multiple packages, all of which might be using autoconf.

	Include <stdint.h> for the C9x types.

./test/h5test.h
	More flushing of stdout for when testing is redirected down a pipe.

./tools/h5ls.c
	Added a `-S' or `--simple' switch which causes the output to be
	simplified somewhat for easier parsing by other scripts. For instance, 
	characters are escaped using a very simple mechanism instead of C's
	more complicated backslash notation, data doesn't have `{}' or `[]'
	characters interspersed for compound and array types, and data is
	printed with exactly one element per line.  This switch is now used by 
	an HDF5-to-HTML CGI script being developed for the DMF people.

./tools/h5tools.c
./tools/h5tools.h
	The repeat threshold which controls how strings are printed when a
	character repeats a bunch of times is now settable at runtime instead
	of compile time. The default is to show all characters, like

	   "abceeeeeeeeeeeeeeeeeeeeeeeeeeeeeefgh"

	But if you set it to something like 5 then any sequence of 5 or more
	characters is replaced by something shorter, like:

	   "abc" 'e'x30 "fgh"	  or

	Added an `str_locale' property which describes how to escape special
	characters in strings. The default is C-like escapes but an
	alternative is ESCAPE_HTML which replaces all non-alphanumeric
	characters with a 3-character HTML escape of the form `%XX'

	Fixed a bug where empty strings didn't even have the quote characters
	printed. Now empty strings show up as `""' instead of absolutely
	nothing.

	Added a `per_line' property which controls the maximum number of
	elements which will appear per line of output. The default is infinity 
	but in practice the right margin causes line breaks. By setting the
	`per_line' value to one and the right margin to a very large value one 
	can achieve output with exactly one element per line.



Changes since 19990826
----------------------

./src/H5O.c				[1.2, 1.3]
	Fixed a read-uninitialized-memory error that resulted in the
	file containing small amounts (<8 bytes each) of uninitialized 
	data. These padding areas (which are never read by hdf5) are
	initialized to zero now.

./MANIFEST
./src/H5Z.c
./src/H5Zdeflate.c			[NEW]
./src/H5Zprivate.h
./src/H5Zpublic.h
./src/Makefile.in
	The zlib filter was moved to a separate file but is still
	automatically defined.

Changes since 19990826
----------------------

./src/libhdf5.settings.in		[1.2, 1.3]
	Added C proprocessor flags and non-library linker flags to the
	description.

./src/H5T.c				[1.2, 1.3]
	Changed return type in tracing macros to H5Tenum_nameof() and
	H5Tenum_valueof().

Changes since 19990825
----------------------

./src/H5O.c				[1.2, 1.3]
	Initialzed the padding area between the end of a message and
	the end of the space allocated for that message. This
	hopefully fixes an UMR error found by Quincey and prevents the 
	file from containing unwanted data.

./tools/h5ls.c				[1.2, 1.3]
	Fixed a bug where the `Data:' tag didn't get printed for
	attributes that have more than five values.

Changes since 19990824
----------------------

./src/H5private.h
	Re-committed recent changes that got clobbered in the pablo update.
	Albert, the source tree should be compilable again now...

./configure.in				[1.2, 1.3]
./configure				[REGENERATED]
./Makefile.in
	Fixed a couple spelling errors.

Changes since 19990820
----------------------

./src/H5D.c
	Added additional elements to a variable initializer in
	H5Dvlen_get_buf_size() to shut up a warning message. Also
	added the API tracing call.

./src/H5F.c
	Added file opening optimizations. If the driver doesn't
	support the ability to determine when two file handles refer
	to the same file (like MPIO and GASS) then H5F_open() makes
	fewer calls to the driver's open callback.  Also, if the
	tentative file access flags are the same as the original flags 
	then H5F_open() makes fewer calls to the file device.

./src/H5FD.c
./src/H5FDprivate.h
./src/H5FDpublic.h
	Added H5FD_get_class() so the library can get information
	about what file driver callbacks are defined. This will be
	useful when more optimization functions are added to the VFL,
	such as for MPIO derived datatype I/O.

./src/H5FDcore.c
./src/H5FDfamily.c
./src/H5FDmpio.c
./src/H5FDmulti.c
./src/H5FDsec2.c
	The driver symbols (like H5FD_CORE, etc) are actually function 
	calls. The functions were fixed to return correct values even
	after calling H5close().

./src/H5FDmulti.c
./src/H5FDmulti.h
	Added support for opening a file when parts are missing (only
	if the caller explicitly allows that in the file access
	property list).

	Moved some common code sequences into macros or functions.

	Added better support for reopening files.  All the application 
	has to know is that the file is a multi file and the base name 
	from which all the member names are created.

	More debugging output when the file is opened with the
	H5F_ACC_DEBUG flag.

	Fixed various bugs.

./src/H5Fistore.c
	Chunked raw data was accidently allocated as meta data instead 
	of raw data.

./src/H5I.c
	The H5Iget_type() function fails when invoked with an old
	object ID (an ID which has been closed down).

./test/h5test.c
	Added an extra argument when setting the multi file access
	property lists so the test fails if it can't open one of the
	sub-files.

./tools/h5ls.c
	Improved the algorithm for deciding what file driver to
	use. It basically tries all of the predefined drivers and is
	now able to open family, split, and multi files without
	looking for special characters in the file name.

	Added `-e' and `--errors' switches which cause errors from
	libhdf5 to be reported on stderr in addition to the simple
	error message displayed by h5ls.

Changes since 19990817
----------------------

./configure.in			[1.2, 1.3]
./configure			[REGENERATED]
	The checking for C9x types includes <stdint.h> if it
	exists. This should fix a bug on Linux RedHat 6.0 (untested).

./src/H5private.h		[1.2, 1.3]
	The prototype for strdup() is protected in case strdup is also
	a macro. This should fix a bug on Linux RedHat 6.0 (untested).


Changes since 19990817
----------------------

./src/H5D.c
./src/H5F.c
./src/H5FDmpio.c
./src/H5Fistore.c
./src/H5Fprivate.h
./src/H5Smpio.c
	The `driver_id' for a file was accidently put in two
	structs. I removed it from the H5F_file_t struct since it's
	really an attribute of the VFL stuff.

	More careful incrementing/decrementing the driver ID to fix a
	memory leak.

./src/H5P.c
	Rewrote H5Pcreate() in terms of H5P_copy() of a default
	property list. This fixes some referencing counting bugs.


Changes since 19990817
----------------------

./src/H5D.c
./src/H5F.c
./src/H5Fistore.c
./src/H5Smpio.c
	Incorporated previous changes into MPIO special cases. These
	are mostly due to the fact that most of the members of the
	file->shared->fapl struct have been moved into the
	file->shared->file->shared struct (`file' is an H5F_t*).

./src/H5I.c
	Fixed a bug with closing the library w.r.t. the VFL stuff. The
	VFL layer introduced reference counts on object ID's and the
	library termination functions freed these objects in the wrong
	order. Now H5I_clear_group() does not normally remove objects
	with a reference count larger than one because it assumes that 
	those objects are currently in use by the library.

Changes since 19990810
----------------------

./MANIFEST
./src/H5FDmulti.c		[NEW]
./src/H5FDmulti.h		[NEW]
./src/Makefile.in
./src/hdf5.h
	The split driver was reimplemented as a more general "multi"
	driver which is capable of splitting data into multiple files
	like the family driver except the partioning is done by memory 
	usage type instead of address. The H5Pset_fapl_split()
	function just calls H5Pset_fapl_multi() with arguments which
	prepare to split the address space into two files: meta and
	raw data.

	This is the first version. I plan to allow the open() call to
	relax a bit which would allow one to open an hdf5 file when
	only the meta-data file is present. This would allow a very
	large file to be split and stored on tape and the relatively
	small meta file to be mirrored on disk to allow limited
	browsing of the file (any request for raw data would fail).

./src/H5private.h
./src/H5F.c
./src/H5FD.c
./src/H5FDprivate.h
./src/H5FDpublic.h
./src/H5FDcore.c
./src/H5FDfamily.c
./src/H5FDmpio.c
./src/H5FDsec2.c
	Added the ability for a file driver to store information in
	the superblock which would be needed if the file were opened
	again later for reading.  The format is driver-defined which
	allows users to extend it however they like.

./doc/html/H5.format.html
	Added information about the new driver information block of
	the superblock. This is where file drivers store information
	they need in order to reopen the file later.


./src/H5F.c
./src/H5Fprivate.h
./src/H5FD.c
./src/H5FDprivate.h
./src/H5FDpublic.h
./src/H5FDcore.c
./src/H5FDfamily.c
./src/H5FDmpio.c
./src/H5FDsec2.c
./src/H5Fistore.c
./src/H5R.c
	The file access properties and the file access property list
	were decoupled, which allows the property list to more cleanly 
	contain properties for various levels of the file and which
	allows the property list to be modified more cleanly when
	opening files.

./src/H5.c
./src/H5FDpublic.h
	Removed H5FD_MEM_META and H5FD_MEM_GROUP since they're never
	used.

./src/H5D.c
	Changed the way we detect the MPIO driver in all these special 
	cases.

./src/H5F.c
./src/H5Rpublic.h
./test/tfile.c
	The default file sizeof(offset) was changed to be a function
	of haddr_t instead of hsize_t.

	THE H5RPUBLIC.H DEFINITIONS WILL HAVE PROBLEMS IF THE USER
	CREATES A FILE WITH NON-DEFAULT OFFSET AND SIZE SIZES!

./src/H5F.c
	Fixed an uninitialized memory access bug in file closing
	related to the VFL.

./src/H5T.c
./src/H5Tpublic.h
	Added an H5T_NATIVE_HADDR predefined datatype which
	corresponds to the `haddr_t' type.

./test/Makefile.in
	Reformatted long lines.

./test/big.c
./test/cmpd_dset.c
./test/dsets.c
./test/dtypes.c
./test/extend.c
./test/external.c
	Removed the H5F_ACC_DEBUG flag from file creation/open calls.

./test/big.c
	Plugged a memory leak.
	
./test/h5test.c
	Added support for the `multi' driver.

	Removed #warning about not having the stdio driver. Plans are
	to not implement it since the sec2 driver serves the same
	purpose and testing didn't show any difference in execution
	times between the two.

Changes since 19990810
----------------------

./src/H5Sprivate.h
	Fixed merge conflicts that I missed earlier.

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.

./src/H5FDsec2.h		[NEW]
	Removed/added files for virtual file layer.

./bin/trace
./src/H5.c
	Removed unused public datatypes and added new VFL public
	datatypes.

	Changed an error message.

./config/BlankForm

./config/hpux10.20
./config/hpux9.03
./config/irix5.x
./config/irix6.x
./config/solaris2.x
./config/unicosmk
	Removed the H5F_OPT_SEEK and H5F_LOW_DFLT constants from the
	configuration since they're no longer applicable. The default
	file driver is always the sec2 driver and it always optimizes
	calls to lseek() or lseek64().

./config/depend.in
	C preprocessor errors generated during automatic dependency
	building are sent to /dev/null to prevent them from appearing
	twice in the make output.

./src/H5T.c
./src/H5detect.c
./test/ohdr.c
	Changed H5F_ADDR_UNDEF to HADDR_UNDEF to be more consistent
	with the `haddr_t' datatype which is now a public type.

./src/H5D.c
./src/H5P.c
./src/H5Ppublic.h
./src/H5Tconv.c
./test/cmpd_dset.c
./test/dsets.c
./test/overhead.c
./test/tselect.c
./test/tvltypes.c
	The H5P_DATASET_XFER constant was changed to H5P_DATA_XFER
	because the properties apply to all types of I/O operations,
	not just datasets.

./src/H5B.c
./src/H5Bprivate.h

./test/h5test.c
./test/istore.c
./testpar/t_dset.c
./testpar/t_file.c
./tools/h5debug.c
./tools/h5ls.c
	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.

	File addresses (the `haddr_t' type) are passed by value
	instead of by reference. The type is no longer a struct. This
	is one of the preliminary changes needed for the Virtual File
	Layer stuff.

./src/H5Fprivate.h	[1.3]
./src/H5Flow.c		[1.3]
	Some address functions were rewritten as macros.


Changes since 19990723
----------------------

NOTE: These bug fixes but have been applied only to the 1.3 branch per 
      Albert's request.

./config/gnu-flags	[1.3]
	Added support for gcc-2.95 by adding full optimization and
	debugging flags and applied a patch from Marcus Daniels.

./src/Makefile.in	[1.3]
	Removes the `libhdf5.settings' file for `make clean'.

Changes since 19990719
----------------------

./configure.in		[1.2, 1.3]
./configure		[REGENERATED]
	Changed $USER to `whoami` for setting the user name in
	libhdf5.settings.

./test/dtypes.c		[1.2, 1.3]
	Fixed the decimal value which is printed for `dst' when an
	error is detected. The hexadecimal value was correct.


Changes since 19990715
----------------------

./Makefile.in		[1.3]
./examples/Makefile.in	[1.3]
./pablo/Makefile.in	[1.3]
./src/Makefile.in	[1.3]
./test/Makefile.in	[1.3]
./testpar/Makefile.in	[1.3]
./tools/Makefile.in	[1.3]
./config/commence.in	[1.3]
./config/conclude.in	[1.3]
./config/depend.in	[1.3]
	Added a `.PATH' target for Irix pmake which is identical to
	the VPATH used by most other `make' programs. Irix 6.5 (or
	6.4?) and later `make' ignores VPATH.

	Started all beginning-of-line comments with `##' instead of
	just `#' because Irix `pmake' barfs on things like the
	following because it sees the `# if' as a directive:

		# make will barf on the following line
		# if running Irix pmake


./config/commence.in	[1.3]
	Added empty definitions for optional `make' macros because
	Irix pmake complains if it sees a macro which has never been
	defined. The main body of the Makefiles can redefine these
	macros to whatever they need.

./bin/release		[1.2, 1.3]
	The SunOS 5.6 version of `sed' must have slashes as delimiters 
	so I made sure that's all that's used in this script even
	though it makes one pattern almost unreadable.
	

Changes since 19990715
----------------------

./src/H5B.c		[1.2, 1.3]
./src/H5Fistore.c	[1.2, 1.3]
./src/H5Sall.c		[1.2, 1.3]
	Replaced second argument of HGOTO_ERROR/HRETURN_ERROR with a
	minor error symbol (H5E_INTERNAL is a major error symbol).

Changes since 19990713
----------------------

./tools/h5tools.c	[1.2, 1.3]
	Fixed a bug reported by Albert: the indices for data printed
	by h5ls were starting over at zero for each pass through the
	strip mining loop.

	Fixed indentation in one function.

	Replaced commented-out code by #if 0


Changes since 19990623
----------------------

./bin/trace		[1.2, 1.3]
./src/H5D.c		[1.2, 1.3]
./src/H5P.c		[1.2, 1.3]
./src/H5T.c		[1.2, 1.3]
	Added definitions for H5D_operator_t, H5MM_allocate_t, and
	H5MM_free_t and regenerated tracing calls for the affected API 
	functions.

./config/gnu-flags	[1.2, 1.3]
	A warning is printed for all versions of EGCS before 2.91.67.

./configure.in		[1.2]
./configure		[REGENERATED]
	Changed defaults: optimizations on, debugging and tracing off.

./bin/h5vers		[1.3]
	Added `use strict' and declared some variables.

./INSTALL		[1.2, 1.3]
	Updated version numbers. Fixed a couple typos.

./h5ls.c		[1.2, 1.3]
	Fixed usage message.

Changes since 19990618
----------------------

./configure.in
./configure		[REGENERATED]
	Now that compound struct conversions don't make so many calls
	to convert their members I turned the H5T debugging back on by 
	default (it will still be disabled in a production version).

./src/H5AC.c
./src/H5B.c
	Made it possible to turn off messages about debugging these
	two packages using the same method as for all other
	packages. Just supply an invalid file descriptor number or use 
	the shell to redirect said descriptor to /dev/null like this:

	    $ HDF5_DEBUG=99,ac,b 99>/dev/null a.out

./src/H5T.c
	Changed the name of the old compound conversion function from
	`struct' to `struct(no-opt)' to be more consistent with the
	new version named `struct(opt)'.

	Fixed a bug in H5T_cmp() that caused any two VL types to
	compare as being equal.

	Removed duplicate code for bitfield comparisons in H5T_cmp().

./src/H5Tconv.c
	Relaxed some constraints in the new compound conversion
	function so it applies to more cases.  Also eliminated a
	memcpy in a tight loop.

./test/cmpd_dset.c
	Added a `--noopt' command line switch which unregisters the
	optimized compound conversion so we can test the non-optimized 
	version.
	
Changes since 19990618
----------------------

./Makefile.in
	Running `make' in the top directory recurses into the examples 
	directory also except if the make target is one of: lib,
	progs, check, test, _test, install, uninstall.

./examples/Makefile.in
	Changed programs into tests, which just means that `make
	tests' does what `make progs' used to do and that `make check' 
	runs the executables.

./src/H5Tconv.c
	Fixed a typo in the unsigned-to-signed native converter for
	large types to small types. This fixes a bug on baldric and
	possibly other machines for the `dtypes' test.

	Also fixed a signed vs. unsigned warning.


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.



Changes since 19990615
----------------------

./README
	Version number synchronized with library.

./bin/h5vers
	If the version number of the library is changed then the first
	line of the README file is also changed to something like

	     This is hdf5-1.2.3 currently under development

	The `release' script (which also gets run by `snapshot')
	changes that line to include the release date but keeps the
	version number the same.  The net effect is that the version
	numbers in README and H5public.h should now always stay
	synchronized.

./bin/snapshot
	The CVS checkin comment includes the version number for the
	snapshot that was just made.

./tools/testh5toh4
	Changed `*-SKIP-*' to `-SKIP-' to be consistent with the other 
	tests.
	

Changes since 19990614
----------------------

./src/H5D.c
	Changed the way the plist_id argument of H5Dvlen_reclaim() is
	checked so that it's more specific and works when debugging is 
	turned off.

./src/H5TB.c
	Removed an unused local variable.

./test/fillval.c
./test/h5test.c
./test/h5test.h
	Changed `basename' variables to `base_name' to prevent a
	warning about a global with the same name.

./tools/h5ls.c
	Changed `indent' variables to `ind' to prevent a warning about 
	a global with the same name.

./tools/h5toh4.c
	Commented out declarations for things that normally appear in
	system header files since our definitions might be
	incompatible with the system and prevent h5toh4 from
	compiling.  If all looks good on other systems then we can
	permanently remove these declarations...


Changes since 19990611
----------------------

./doc/html/H5.format.html
	Added documentation for opaque data types (bitfield types were 
	already documented but they were out of order).

./src/H5E.c
	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.


Changes since 19990608
----------------------

./configure.in
./configure			[REGENERATED]
./src/H5T.c
./src/H5Tpkg.h
./src/H5Tpublic.h
./src/H5config.h.in		[REGENERATED]
./src/H5detect.c
./src/H5private.h
	Added checks for the C9x integer types like int32_t,
	int_least32_t, and int_fast32_t and the unsigned
	versions. HDF5 defines H5T_NATIVE_* versions (all caps) to be
	the same as the type provided by the C library, otherwise it
	defines them as integers exactly the specified size. Hardware
	type conversion functions are used when the types
	match some C-language type (like `int').

./configure.in

./src/libhdf5.settings.in	[NEW]
./config/conclude.in
./INSTALL
./MANIFEST
	A file called `libhdf5.settings' is installed along with the
	libraries and it contains a list of various things that might
	be of interest to someone using the library (such as what
	compiler/options were used and what other libraries might need 
	to be linked to satisfy external references).  We can add more 
	things as it becomes necessary. Here's a sample...

Changes since 19990607
----------------------

./tools/h5ls.c
./tools/h5tools.c
	Added support for printing bitfields and opaque data.

./test/dsets.c
	Added bitfield and opaque datasets to the output file so h5ls
	has something interesting to print.

./test/trefer.c
	Resync'd

./src/H5Tconv.c
	Fixed bitfield conversion which resulted in possible garbage
	in high-order bits of destination when the destination type is
	larger than the source type. Thanks for spotting it, Quincey.

Changes since 19990607
----------------------

./tools/h5tools.c
	Finished code which prints references (object and dataset
	region). Patrick, if you tell me how h5dump should (or might
	want to) print references I can make some changes to support
	various formats...

	You can try it out with:

	    cd test
	    env HDF5_NOCLEANUP=yes ./testhdf5
	    ../tools/h5ls -dvr trefer1.h5
	    ../tools/h5ls -dvr trefer2.h5

	(run h5ls with no arguments if you forgot what the switches do)
	

./test/trefer.c
	Call calloc instead of malloc in one place to prevent
	uninitialized data from being written into the file.

Changes since 19990607
----------------------

./tools/h5ls.c
./tools/h5tools.c
./tools/h5tools.h
	Finished the `-x' or `--hexdump' switch, which causes all data 
	to be printed in hexadecimal format with no translation from
	file to memory data type.

Changes since 19990602
----------------------

./doc/html/Datatypes.html
./test/dtypes.c
	Added documentation and tests for opaque types.

./tools/h5ls.c
	Added a `-x' or `--hexdump' argument which is not fully
	implemented (because I want to synchronize h5tools.c first)
	but which will eventually print raw data in hexadecimal format 
	without any translation from disk. This would be useful for
	debugging references and VL types.

./tools/h5tools.c
	Added support for references (not quite finished yet, but
	compiles -- I wanted to sync up this file before Patrick and I 
	got too far apart...)


./src/H5R.c
	Checked for error return value from H5R_get_object_type()

./src/H5A.c
./src/H5D.c
	Changed error return values from NULL to FAIL

./test/Makefile.in
./test/trefer.c
	Creates trefer1.h5 and trefer2.h5 so that the second test
	doesn't clobber the first file since the files might be useful 
	for debugging.


Changes since 19990430
----------------------

Remove changes from CVS

./bin/release
	Added a `--nocheck' switch which causes the script to not
	check the contents of the MANIFEST file against CVS. This is
	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
	type for `eof_written' from `uint' to `uintn'. Shouldn't this
	really be `hbool_t'?

./src/H5Odtype.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tpublic.h
./test/dtypes.c
./doc/html/H5.format.html
	Added support for bitfields and opaque data types.

Changes since 19990427
----------------------

./tools/h5ls.c
	Added a `--address' (`-a') switch which causes h5ls to display 
	file addresses for raw data. For contiguous datasets it's just 
	a nice simple number, but for chunked datasets it's a list of
	logical dataset coordinates, file addresses, filter masks, and 
	storage sizes.

	Changed `--dump' switch to `--data'.

./src/H5D.c
./src/H5F.c
./src/H5Fprivate.h
	Enhanced the indexed-storage B-tree iterator so it can dump
	raw data addresses (and other info) to the standard error
	stream.

	Added H5Ddebug() so h5ls has a way to dump addresses for
	datasets. I'm not sure what else this API function should do,
	so I think we should discuss it before we document it. So far, 
	h5ls is the only thing that uses it, and we can easily change
	that.

./src/H5Tconv.c
./test/dtypes.c
	Finally had a chance to verify Paul's H5T_conv_s_s (general
	string to string conversions) bug fixes and incorporate them
	into H5T_conv_f_f (general floating-point to floating-point
	conversions) and H5T_conv_i_i (general integer to integer
	conversons). Thanks Paul.

./src/H5D.c
./src/H5S.c
./src/H5Sprivate.h
	Added performance timers around data space read and write
	callbacks. They were already there for the gather/scatter
	callbacks.

	The timings for read/write callbacks are displayed along with
	gather/scatter when data space debugging is turned on.

./bin/iostats
	Updated to print totals. Added a `--fast' option that doesn't
	do any output except the totals and is much faster.

./bin/trace
	Changed __unused__ to UNUSED to match source code.

./config/gnu-flags
	Updated error message for pgcc. I've sent bug reports to the
	pgcc people but the new version still has the same bug.

./configure.in
./config/conclude.in
./config/depend.in
	Fixed dependencies for non-GNU makes when run in a directory
	other than the hdf5 source tree.

	Updated GNU `make dep' rules to copy the distributed
	dependencies for non-GNU makes into the source tree when run
	in some other directory.

Changes since 19990426
----------------------

./tools/h5tools.c
./tools/h5tools.h
	Finally fixed a long-standing bug that caused core dumps if
	a compound datum rendered to more than some number of
	characters (we kept bumping up the limit at the risk of
	violating stack size limits on some machines). The fix works
	only on systems that have the vsnprintf() function (otherwise
	a 4kB limit is imposed, which if violated probably dumps
	core). If vsnprintf() is present then the library dynamically
	allocates space for the output string.

	Also made it possible to control how compound data is rendered 
	across multiple lines of output by allowing the caller to
	specify where optional line-breaks get inserted. The output
	functions split up the value at one or more optional
	line-breaks to prevent it from wrapping around the screen.

	If a datum doesn't fit on the current line but would fit on
	the next line then it is printed on the next line regardless
	of whether optional line-breaks would have prevent wrapping
	around the screen. This makes it easier to find the beginnings 
	of compound data values.  This feature is disabled by default
	but can be enabled by the application.

	If a datum doesn't fit on the current line and the previous
	datum also occupied more than one line then we move to the
	next line before printing. This makes it easier to find the
	beginnings of compound data values but prevents the output
	from looking fragmented if there are only a few long values
	among mostly short values.  This feature is disabled by
	default but can be enabled by the application.

	The application can control the printf() formats used for all
	the native data types. The defaults are what the library used
	to use: %g, %ld, %lu, %d, and %u

./tools/h5ls.c
	Compound datatype values can now be split across multiple
	lines of output instead of just wrapping. Also, when lots of
	compound values are too long they all start at the beginning
	of a line. This only required about 10 lines of changes in the 
	setup for tools library calls (I didn't modify the h5dump
	program because it uses its own version of the tools library
	that forked off long ago).

	Added code for Win32 which is unable to cast `unsigned long
	long' to `double'. If the dataset size exceeds (2^63)-1 then
	the percent utilization is not displayed (this is easily
	possible with chunked datasets). This is untested yet.

./configure.in
./src/H5config.h.in
./src/H5.c
./src/H5private.h
	Check for vsnprintf() and provide a simple, stupid definition
	if it isn't available. The stupid definition just calls
	vsprintf() and ignores the second argument. This can result in
	buffer overflows in h5ls and h5dump since vsprintf() is an
	unsafe function (and anyone can create an hdf5 file that runs
	an arbitrary command from h5ls and h5dump in that case)!

./config/conclude.in
	Remove more *.o files for `make clean'

./src/H5A.c
./src/H5D.c
./src/H5F.c
./src/H5I.c
./src/H5Iprivate.h
./src/H5P.c
./src/H5R.c
./src/H5RA.c
./src/H5S.c
./src/H5T.c
./src/H5TB.c
	Cleaned up a memory leak during H5_term_library() by allowing
	H5I_clear_group() to skip items that couldn't be freed. This
	allows the item to remain in the group until we can free it
	later.

./src/H5F.c
	The H5F_close_all() function fails if a file cannot be closed.

Changes since 19990426
----------------------

./config/commence.in
./examples/Makefile.in
./test/Makefile.in
./testpar/Makefile.in
./tools/Makefile.in
	Fixed some dependency problems in Makefiles. If the library
	version is updated then everything gets recompiled.

./src/H5G.c
./src/H5R.c
	Failure return value for object type functions is now
	H5G_UNKNOWN as documented.

./src/H5Shyper.c
./src/H5Spoint.c
	Fixed an unused argument warning.

./tools/h5debug.c
	Fixed a call to H5F_block_read() since the 4th argument is
	different now.

./tools/h5ls.c
	Added a space between the object name and class to make the
	output readable when the object name is longer than 24
	characters.

./src/H5HG.c
./src/H5HL.c
./src/H5O.c
	Changed H5F_block_read/write() to take a file transfer
	property list instead of just a parallel I/O mode. This will
	allow us to pass additional parameters to the I/O functions
	without having so many arguments to worry about.

	This fixes a bug I introduced last Friday for parallel HDF5

./src/H5B.c
	Fixed decoding of B-tree keys when iterating through the
	leaves of the B-tree. This fixes a bug for applications that are
	adding new entries to groups and also listing the groups.

Changes since 19990415
----------------------

./config/depend.in
	Fixed automatic dependencies. We were storing dependencies for
	*.o files instead of *.lo files after shared libraries were
	added.

./config/gnu-flags
./config/linux-gnulibc1
	Moved `-march=pentiumpro -mcpu=pentiumpro -malign-double' from 
	the linux file to this file and caused it to depend on the CPU 
	name.  This fixes one of Elena's bugs.

./src/H5Sprivate.h
./src/H5Tpublic.h
./test/istore.c
	Added an H5Dget_storage_size() function that reports the
	amount of storage allocated for raw data in a dataset.

	Changed H5D_xfer_* to H5F_xfer_* because these properties are
	more general than datasets. This also allows some of the
	lower-level I/O functions to get this information easier.

./src/H5S.c
./src/H5Sall.c
	Added two new functions H5S_all_read() and H5S_all_write()
	which are optimizations that copy data directly between file
	and memory without having to go through the scatter gather
	step.  This knocks quite a bit of time off the I/O and
	reading/writing entire datasets is a fairly common operation.

./tools/h5ls.c
	Reports the logical size of data, the allocated size of data,
	and the percent utilization.

./MANIFEST
	Removed old pablo files, added new files. Snapshots should now
	start to work again.

./src/H5D.c
./src/H5Fmpio.c
	Removed two warnings signed vs. unsigned comparisons and check 
	for overflow.

./config/commence.in
./config/conclude.in
./test/Makefile.in

	Changed `__unused__' to `UNUSED' to fix a conflict with GNU
	header files.

./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.

Changes since 19990330
----------------------

./src/H5A.c
./src/H5D.c
	The `bkg' buffers are zeroed before calling the type
	conversion function. This fixes a problem where reading a file 
	compound data structure into memory results in garbage between
	the members.

./src/H5I.c
	Fixed H5I_clear_group() so it removes entries even when a free 
	callback is not registered. This fixes fixes an `infinite loop 
	closing library' warning message.

./src/H5.c
	Added ellipses to the end of the infinite loop message.

Changes since 19990322
----------------------

./configure.in
./configure		[REGENERATED]
./src/H5D.c
./src/H5O.c
	Removed H5AC, H5B, and H5T from the default list of packages
	to debug (because they're pretty expensive debugging), and
	added H5O. Also fixed a bug for undefined variable in H5D when 
	H5S debugging is turned on but H5T debugging is turned off.

./config/conclude.in
	Fixed installation of header files for building in a directory 
	other than the source directory. This fixes a bug where
	H5config.h wasn't being installed.

./src/H5TB.c
./src/H5Tprivate.h
./src/H5Z.c
./src/H5detect.c
./src/H5private.h
	Changed the way the library shuts down again. Now it handles
	cycles between packages and isn't so sensitive to dependencies 
	between packages. A package might shut down only to be
	restarted to process a request from some other package being
	shut down.  Loops are detected after 100 iterations and the
	shutdown is aborted with a message on standard error.  This
	also makes it a lot easier to debug.

./src/H5A.c
	Fixed H5A_write() and H5A_read() so they pass a non-null
	background buffer to the conversion functions. This is
	necessary when an attribute has a compound data type.

./src/H5Flow.c
./src/H5Fprivate.h
./src/H5Fsec2.c
	Reindented new Win32 stuff.

./src/H5Odtype.c
	Fixed a bug when enumeration types are used in a compound data 
	type. The byte pointer wasn't incremented after the type
	information was written.

./tools/h5ls.c
	Compound data types display their total size because it's not
	always obvious from looking at the members.

	Scalar attributes show their space as `scalar' instead of
	`{}'.

	The index value is not printed for attributes that have only a 
	few values. Instead the word `Data:' is printed on the first
	line of attribute data.

	Named types display their data type only if verbose output was 
	requested.

./configure.in
./configure		[REGENERATED]
./config/commence.in
	A few tweaks to the makefile rules for rebuilding makefiles.

./tools/testh5dump.sh
	Changes that allow hdf5 to be configured and compiled in a
	directory other than the source directory. This is especially
	useful if you want to concurrently compile with different
	compilers and/or compile flags, or if the hdf5 source is on
	read-only media like a CDROM.  The changes were surprisingly
	easy ;-) Here's what you can do now...

		  $ mkdir /tmp/build1  # or something
		  $ cd /tmp/build1
		  $ /cdrom/hdf5/configure # where ever the source is
		  $ make

	Paul, you'll have to change the testh5toh4 script similar to
	the way I changed testh5dump.sh.  I started working on it but
	then gave up because of a number of problems: (1) I had to
	comment out all the tests that let h5toh4 choose the output
	file name because it always tried to put the output file in
	the same directory as the input file, (2) if path names are
	used during the h4 dump then they interfere with the
	diff. The test works fine when run in the source directory,
	but try this instead:

	    $ gunzip <hdf5-1.1.67.tar.gz |tar xf -
	    $ chmod -R ugo-w hdf5-1.1.67
	    $ mkdir build
	    $ cd build
	    $ ../hdf5-1.1.67/configure
	    $ make check

	Dan, I didn't modify the pablo/Makefile.in because I have no
	way to test it. I think all you need to do is add a couple
	lines before the @COMMENCE@ line and add a couple search
	directories for header files. Anyway, it seems like almost an
	exact duplicate of the src/Makefile.in, so it shouldn't be a
	problem...

./Makefile.in
	Removes a few more temporary files during make clean and
	distclean.

./configure.in
	I fixed the creation of the time-stamp files so that the
	initial make doesn't have to regenerated all the makefiles
	(only GNU make users will see any change).

./src/H5R.c
	Changed a return type from `intn' to `int' for an API
	function.

./src/H5detect.c
	Added the volatile qualifier to a couple more variables.

./tools/h5tools.c
	Fixed a compiler warning about an unused local.

./tools/h5toh4.c
	Initialized `optind' to 1 because it's zero on my system. It
	should always be one on a unix system.

./tools/testh5toh4
	Redirected "broken pipe" messages to /dev/null so outut is
	formatted correctly.

Changes since 19990312
----------------------

./configure.in
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
./src/H5private.h
	Temporarily commented out the code that tries to link a simple
	MPI-IO application because I'm not sure how to pass $LDFLAGS
	and $LIBS to the compiler.

	Removed the `--enable-parallel=ibm' switch because the library 
	we link with is either -lmpcc or -lmpcc_r but not both. The
	only way to tell is to see what compiler was specified (mpcc
	or mpcc_r) but if that compiler is specified then we don't
	need any libraries (the compiler script supplies them). That
	leaves just two choices: the user must use a compiler script:

	    CC=mpcc ./configure

	or the user must state which library is desired:

	    LDFLAGS='-lmpcc' ./configure --enable-parallel

	Checks for <setjmp.h>, longjmp(), and signal(). We don't check 
	for setjmp() because it could be a macro (in fact, Posix
	requires it to be a macro) and if longjmp() is present then
	setjmp() is probably present too ;-)

./src/H5detect.c
	The alignment detection loop uses SIGBUS and setjmp/longjmp
	instead of fork/wait in order to get around bugs with forking
	in conjunction with mpich.

./test/Makefile.in
./testpar/Makefile.in
./tools/Makefile.in

./configure		[REGENERATED]
./MANIFEST
	Changed the names of the IBM-SP2 config files by replacing the
	minor version numbers with an `x'.  The solaris config warns
	about old versions of gcc.

	The RUNSERIAL value is set to the empty string by default. The
	config/* file (or user) can override it by setting it to some
	other value.

	The `--enable-parallel' with no flags turns on the
	HAVE_PARALLEL constant in the source code but doesn't add any
	MPI or MPI-IO libraries to the link line.

	If we are compiling for parallel then configure checks that we 
	can actually link a very simple program. This has the benefit
	of detecting config errors before we waste time compiling the
	entire library.

	Configure recognizes `mpcc_r' as a parallel compiler.

./src/H5A.c
./src/H5Apublic.c
	Fixed some compiler warnings.  Changed the return type of

	never be larger then memory.

./config/gnu-flags	[NEW]

Changes since 19990302
----------------------

./INSTALL
./configure.in
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
	Improvements for parallel library.  If you have a properly
	working mpicc you should be able to just say:

	    $ CC=mpicc ./configure

	and you will see

	    checking for mpirun... /usr/local/mpi/bin/mpirun
	    checking for parallel support files... skipped
	    checking how to run on one processor...
		     /usr/local/mpi/bin/mpirun -np 1
	    checking how to run in parallel...
		     /usr/local/mpi/bin/mpirun -np $$NPROCS

	To quote from the INSTALL file....

	*** Parallel vs. serial library
	The HDF5 library can be configured to use MPI and MPI-IO for
	parallelizm on a distributed multi-processor system. The easy
	way to do this is to have a properly installed parallel
	compiler (e.g., MPICH's mpicc or IBM's mpcc) and supply that
	executable as the value of the CC environment variable:
	[NOTE: mpcc is not tested yet]

	    $ CC=mpcc ./configure
	    $ CC=/usr/local/mpi/bin/mpicc ./configure

	If no such wrapper script is available then you must specify
	your normal C compiler along with the distribution of
	MPI/MPI-IO which is to be used (values other than `mpich' will 
	be added at a later date):

	    $ ./configure --enable-parallel=mpich

	If the MPI/MPI-IO include files and/or libraries cannot be
	found by the compiler then their directories must be given as
	arguments to CPPFLAGS and/or LDFLAGS:

	    $ CPPFLAGS=-I/usr/local/mpi/include \
	      LDFLAGS=-L/usr/local/mpi/lib/LINUX/ch_p4 \
	      ./configure --enable-parallel=mpich

	If a parallel library is being built then configure attempts
	to determine how to run a parallel application on one
	processor and on many processors.  If the compiler is mpicc
	and the user hasn't specified values for RUNSERIAL and
	RUNPARALLEL then configure chooses `mpirun' from the same
	directory as `mpicc':

	    RUNSERIAL:    /usr/local/mpi/bin/mpirun -np 1
	    RUNPARALLEL:  /usr/local/mpi/bin/mpirun -np $${NPROCS:=2}

	The `$${NPROCS:=2}' will be substituted with the value of the
	NPROCS environment variable at the time `make check' is run
	(or the value 2).

./testpar/Makefile.in
	Saying `make check' (or `make test') will run the tests on two 
	processors by default.  If you define NPROCS then that many
	processors are used instead:

	    $ NPROCS=4 make check

./configure.in
	Fixed (hopefully) bugs with detecting whether __attribute__
	and __FUNCTION__ are special keywords for the compiler.

./Makefile.in
	Saying `make install' from the top level directory shows
	instructions for using shared libraries.

./config/commence.in
./src/Makefile.in
./test/Makefile.in
./testpar/Makefile.in
./tools/Makefile.in
	Moved the @top_srcdir@ into the makefiles because it was
	expanded too early and had the wrong value.

./INSTALL
	Added a warning that if the wrong version of hdf4 tools are
	installed then `make check' will fail in the tools directory.


Changes since 19990301
----------------------

./INSTALL
	Reorganized and added some additional examples.

./MANIFEST
./aclocal.m4			[NEW]
./configure.in
./configure			[REGENERATED]
./src/H5config.h.in		[REGENERATED]
./bin/ltconfig			[NEW]
./bin/ltmain.sh			[NEW]
	Added tests to determine how to compile shared libraries and
	how to link programs with them before the libraries are
	installed.  Also how to install and uninstall shared
	libraries. The configure step also prints the names of the
	config files it's trying to load for easier debugging.

./bin/config.guess
./bin/config.sub
	Replaced with a newer version from GNU.  The changes we made
	to that file to report `irix6.x' and `FreeBSD' without version
	numbers have been incorporated into configure.in instead.  In
	the future, do not change these two files (see the top of
	configure.in instead). By the way, this update was required to 
	get shared libraries working.

./config/linux			[REMOVED]
./config/linux-gnulibc1		[NEW]
./config/linux-gnu		[NEW]
./config/alpha-dec		[REMOVED]
./config/alpha-dec-osf4.0	[REMOVED]
./config/dec-osf4.x		[NEW]
./config/irix5.3		[REMOVED]
./config/irix5.x		[NEW]
./config/irix64			[REMOVED]
./config/freebsd
	Moved config files around to agree with output from the new
	config.guess.  The linux file was split into gnu (RedHat),
	gnulibc1, and gnulibc2 versions. The alpha-dec file was
	removed (I think it was unused) and the alpha-dec-osf4.0 was
	changed to dec-osf4.x. The irix5.3 file renamed to irix5.x and
	the irix64 file was renamed to irix6.x. The freebsd file was
	changed to point to linux-gnulibc1. These changes were tested
	on:

		Linux 2.0
		Linux 2.1
		FreeBSD 3.2
		Irix 5.3
		Irix64 6.2
		Irix64 6.4
		HP/UX 10.20
		OSF1 4.0

./config/alphaev56-dec-osf4.x
./config/irix64
	Added warnings similar to linux/freebsd about using compilers
	with known bugs.

./config/commence.in
./config/conclude.in
./src/Makefile.in
./test/Makefile.in
./testpar/Makefile.in
./tools/Makefile.in
	Added definitions for shared libraries. This has been tested
	on the following systems:

		Linux 2.0
		Linux 2.1
		FreeBSD 3.2
		Irix 5.3
		Irix64 6.2
		Irix64 6.4
		HP/UX 10.20		static only
		OSF1 4.0

	If you want to disable use of shared libraries (you probably
	do for development purposes since it takes a lot longer to
	compile and because you have to run dynamically linked
	programs in a special way if the library hasn't been
	installed) then add `--disable-shared' to the configure
	command line.  This is all documented in the INSTALL file.

./bin/release
	Temprarily commented out the MANIFEST checking when running
	under svf since svf is about to be replaced by a newer
	version.  This change only affects error checking during the
	release process.

./Makefile.dist
./Makefile.in
	Added `make check' which does the same thing as `make _test'
	since the former is endorsed by the GNU coding style and
	people are used to it.  The old `make _test' still works too
	(and so does `make test' if you use GNU make).

Changes since 19990226
----------------------

./INSTALL
	Added instructions for using other compilers on Irix platforms.

./configure.in
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
./src/H5private.h
	The presence of <sys/sysinfo.h> and <sys/proc.h> is only
	checked on DEC/Alpha because there are too many problems
	including these headers on other systems.

./config/irix6.x
./config/irix64
	Removed `-ansi' and added a comment. Converting an ASCII UTC date
	and time to a time_t value is not defined by ANSI or Posix but 
	is available if we don't use `-ansi'.  This allows the dataset 
	modification time messages to be read properly by
	H5Gget_objinfo().

./src/H5Tconv.c
	Fixed a compiler warning.

./test/dtypes.c
./test/hyperslab.c
./test/istore.c
	Fixed compiler warnings in printf() statements.

Changes since 19990225
----------------------

./INSTALL
	Added warnings and a disclaimer about GNU, DEC, Irix64, and NT
	compilers that generate incorrect machine code.

./configure.in
./src/H5private.h
	Detects and includes <sys/param.h> which is needed on FreeBSD
	before <sys/proc.h> even though we only really using anything
	from <sys/proc.h> on the DEC Alpha.

./config/irix64
	Turned off warnings for duplicate definitions from the linker
	because -lnsl on irix has the same stuff in it as -lc.

./config/irix6.x
	Split up the CC and CFLAGS settings like with irix64 so that
	compilers besides `-n32' can be used.

./bin/snapshot
	The snapshots are tagged with names like hdf5-1_1_52 which is
	similar to the way the releases are tagged (cvs doesn't allow
	dots in tags).

./test/dtypes.c
./src/H5private.h
./src/H5Tconv.c
	Fixed some alignment violations on the DEC when using high
	optimization levels. The DEC incorrectly optimizes certain
	memcpy() and memmove() calls when the source argument is not
	word aligned if the call looks like it's copying an atomic
	data type.

./test/hyperslab
	Worked around code generation bugs in the Irix64 Mongoose 7.00 
	compiler by casting some `unsigned long' values to `unsigned'
	in an expression.

./src/H5Ocomp.c
	Fixed a place where %d was used to print a size_t.

Changes since 19990225
----------------------

./configre.in
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
./src/H5detect.c
./src/H5private.h
	Checks for existence of <sys/sysinfo.h>, <sys/proc.h> and
	setsysinfo() needed on the DEC Alpha to turn off UAC fixing by
	the OS.

Changes since 19990219
----------------------

./config/irix64
	The old (-32) compiler is now supported by setting envrionment
	CC='cc -32'. The -64 compiler is the default or you can set

	Ruey-Hsia.

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

./src/H5F.c
./src/H5private.h
./src/H5Ipublic.h
./src/H5O.c
	Fixed a rather nasty bug with file closing that caused the
	file boot block to be updated incorrectly, effectively
	truncating the file.  The bug I fixed was triggered by:

	    1. Create a file, F
	    2. Open an object, X
	    3. Close file F
	    4. Reopen file F for read/write.
	    5. Create and close some objects
	    6. Close file F
	    7. Close library (exit).

	Step 3 pended the close because object X is still open, but
	the file ID was removed from the H5I_FILE ID group. Step 4
	created a new file because it didn't see any matching file on
	the H5I_FILE ID group.  Step 5 extends the file. Step 6 writes 
	the new file boot block to disk. Step 7 closes object X and
	completes the close from step 3, writing the old boot block
	information to disk.

	The new behavior is that step 3 moves the file from the
	H5I_FILE group to the H5I_FILE_CLOSING group. Step 4 searches
	both groups and finds the file. Step 5 extends the file using
	the same H5F_file_t struct as step 3. Step 6 closes the H5F_t
	struct opened in step 3 but not the H5F_file_t struct shared
	by steps 1 and 3. Step 7 closes object X which closes the
	H5F_file_t from step 1, flushing the boot block which was
	shared by all steps.

./src/H5F.c
	Added some bulletproofing to file reference counting and
	removed comments which no longer apply.  Added H5F_flush_all() 
	and H5F_close_all() which apply to all files.

./src/H5I.c
./src/H5Iprivate.h
./src/H5R.c
./src/H5RA.c
./src/H5S.c
./src/H5T.c
	Added the new H5I_free_t data type to describe the function
	type to be passed as the `free_func' argument to
	H5I_init_group().

./src/H5I.c
	Bulletproofed the object removal functions. Removed comments
	which no longer apply. Changed global variable names so they
	don't violate the naming scheme. Added H5I_debug() that prints 
	the contents of an ID group.  Removed H5I_inc_ref() because it 
	isn't used. Reindented a couple of functions.

./src/H5.c
./src/H5G.c
./src/H5Ipublic.h
	Changed H5I_MAXID to H5I_NGROUPS to better relect the fact
	that it's the total number of valid ID groups.

./src/H5Shyper.c
	Changed hyperslab offset arrays to signed quantities to get
	rid of warnings on DEC cluster.

./src/H5Flow.c
./src/H5Fprivate.h
	Changed the objno argument of H5F_addr_pack() to be unsigned
	to get rid of warnings on DEC cluster.

Changes since 19990215
----------------------

./src/H5.c
	Fixed more dependency problems in H5_term_library(). There was
	a bug in the previous version that could cause the wrong EOF
	marker to be written to the boot block under certain
	circumstances. Hopefully this fixes it although I don't ready
	access to a test case (Mark Miller will test it).

./src/H5F.c
./src/H5Fprivate.h
	Added an H5F_close_all() that is similar to
	H5F_term_interface() but which doesn't close the
	interface. Files that don't have open object headers are
	closed, others are delayed until all object headers close. All
	files are flushed.

./configure.in
./acconfig.h
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
./src/H5public.h
./src/H5Omtime.c
	Check for <stddef.h>

	Checks for `__tm_gmtoff' in `struct tm' because old versions
	of GNU libc are different than recent versions. This fixes the 
	failing mtime test.

./bin/config.guess
./config/freebsd2.2.7	[REMOVED]
./config/freebsd	[ADDED]
	Changed the name so it works with all versions of FreeBSD.

./src/H5.c
	Moved H5F after H5T and H5G in H5_term_library() to satisfy
	dependencies.

./src/H5G.c
	Fixed a bug that caused H5Gcreate() to fail if the group name
	had trailing slashes.

./src/H5Gpublic.h
	Changed `group_name' to `name' in a prototype.

./src/Makefile.in
	Dynamic library on Linux, but needs for work to be generally
	useful.

./src/H5HG.c
./src/H5HGprivate.h
	Fixed alignment problems when using old GCC compilers (like
	the one shipped with RedHad Linux).

./tools/h5ls.c
	Fixed a bug where the contents of the root group could be
	listed twice if there was a link back to the root
	group. Similarly for groups that are mentioned on the command
	line.

	Fixed a bug where unknown types were printed with a random
	type class number.

./src/H5T.c
./src/H5Tconv.c
./src/H5Tprivate.h
	Fixed O(log N) conversion bugs.

Changes since 19990118
----------------------

./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 terminal 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.

./test/dtypes.c
	Wrote some data to an attribute to test h5ls attribute
	printing.

./src/H5private.h
./src/H5public.h
	Reindented function prototypes after `HDF5API' was added. Also 
	rewrapped long lines.

./src/H5Flow.c
	Added an `#ifdef WIN32' around an unused variable.

./src/H5api_adpt.h
	Removed extra carriage returns inserted by "broken" operating
	system.

./src/H5Dprivate.h
./src/H5Oprivate.h
./src/H5Vprivate.h
./src/H5private.h
	Removed extraneous inclusion of H5api_adpt.h since it's
	included in H5public.h which is included by everything.

./src/Makefile.in
	Added H5api_adpt.h to the list of public header files to fix
	broken `make install'.

Changes since 19990105
----------------------

./INSTALL
./doc/html/Compression.html
./doc/html/Filters.html
	Disassociated GNU from zlib.  Did not change the introduction
	which incorrectly states that compression in hdf5 is available 
	only if GNU gzip is available (should read zlib).

	Changed a typo in INSTALL to match what is documented in
	various other places: that zlib 1.1.2 (not 1.0.2) or better is 
	required for compression.

	Added a reference to the main zlib web page in various places.

./src/H5Fistore.c
	Fixed a typo in a comment.

./src/H5Flow.c
	Removed carriage returns from the end of lines.

./test/dsets.c
	The deflate compression tests are still run but `-SKIP-' is
	printed instead of `PASSED' if the zlib library was not
	detected at configuration time. The tests check that the
	compression layer (H5Z) is correctly bypassed.


Changes since 19981217
----------------------

./MANIFEST
	Removed some ddl files from tools/testfiles that are no longer
	part of CVS.  Added new enum.c test.

./configure		[REGENERATED]
./configure.in
	Changed printf long long format detection to favor `L' over
	`ll'.

./src/H5.c
./src/H5private.h
	Renamed `library_initialize_g' to `H5_libinit_g' to make it
	conform to our naming scheme.

./src/H5I.c
	Fixed a bug in H5I_dec_ref() that caused the return value to
	always be zero instead of the new reference count.

./src/H5.c
./src/H5Odtype.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
./test/Makefile.in
./test/dtypes.c
./test/enum.c		[NEW]
	Added support for enumeration data types.

./src/H5RA.c
	Renamed H5T_insert() to H5T_struct_insert() and added
	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.

./test/fillval.c
./test/istore.c
	Fixed memory leaks during error handling.

./tools/h5ls.c
	Displays enumeration type information.

./tools/h5tools.c
	Displays enumerated data using symbol names.
	
./src/H5public.h
	Include <limits.h> because the H5T_NATIVE_CHAR macro needs the
	definition for CHAR_MIN.

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.

./config/alpha-dec-osf4.0
	Added more warning and optimization switches to the native
	compiler.

Changes since 19981207
----------------------

./MANIFEST
	Added tcompound2.{dmp,h5} and tdset2.{dmp,h5} used by the
	h5toh4 testing.

./configure.in
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
	Added check for <sys/timeb.h> for Win32.

	Determines sizeof(char) just so we have a complete list of
	type sizes defined as preprocessor symbols.

./src/H5detect.c
./src/H5T.c
./src/H5Tpkg.h
	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
	simulate architectures that have alignment constraints on
	architectures that don't.

	Changed typo SIZEOF_LDOUBLE to SIZEOF_LONG_DOUBLE in a few
	places.


Changes since 19981125

./src/H5HG.c

./tools/h5toh4.c
./tools/h5tools.c
	Renamed the old H5T_NATIVE_CHAR type to H5T_NATIVE_SCHAR to
	denote that it is always signed.

	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.

	NOTE: THERE ARE OTHER DOCUMENTATION FILES THAT I DIDN'T CHANGE 
	BECAUSE I CAN'T MODIFY THE SOURCE.

./test/extend.c
	Swapped two lines to prevent diagnostic messages from messing
	up the formatted output.

Changes since 19981124
----------------------

./src/H5T.c
	Fixed a typo in the registration of the `unsigned char' to
	`unsigned long long' type conversion that caused it to not be
	registered, falling back to software whenever that conversion
	path was taken.

./MANIFEST
./test/Makefile.in
./test/testhdf5.c

./test/theap.c		[REMOVED]

./test/tohdr.c		[REMOVED]
./test/ohdr.c		[NEW]
./test/tstab.c		[REMOVED]
./test/stab.c		[NEW]
	Removed the `t' from the front of these names and made each
	test a stand-alone program following the format of most of the 
	other tests.

./test/big.c
	Uses libh5test.a but always sets the low-level driver to 1GB
	file family.

	The `#if' near the top to set the data space to 8GB has been
	simplified now that `long_long' is always defined and the
	error message is improved when `long_long' isn't wide enough.

	Cleanup code was added to the error handling.

./test/gheap.c
./test/istore.c
	Uses libh5test.a.  Added error cleanup code.

./test/dtypes.c
./test/h5test.c
	Added 68 new tests that check hardware and software
	conversions between `long long' and `unsigned long long' and
	the other integer types.  The tests only run on machines where 
	sizeof(long_long)!=sizeof(long).  We test a total of 180
	different integer conversions, half in hardware and half in
	software.

	Cut down the number of times each test is run from 5 to 1 so
	it doesn't take so long.  If you want to run more times
	there's a constant that can be changed at the top of the file.

./test/extend.c
	Removed unused variable.

./test/h5test.c
./test/h5test.h
./test/external.c
./test/fillval.c
	The h5_cleanup() returns true/false so it can be used in an `if'
	statement to clean up additional files.

./doc/html/Environment.html
	Indented.  Added HDF5_PREFIX and HDF5_DRIVER descriptions.

./src/H5P.c
	Changed the trace type for the second argument from `Iu' to
	`x' since it's an output parameter.

./INSTALL
	Added a warning that the GNU zlib that comes with the latest
	version of HDF4 is too old to use with HDF5 and must be
	renamed so configure doesn't see it when `--enable-hdf4' is
	used.

Changes since 19981121
----------------------

./src/H5Tconv.c
	With my poor eyesight I missed the definitions of SCHAR_MIN
	and SCHAR_MAX in <limits.h> and used CHAR_MIN and CHAR_MAX
	incorrectly. I changed all occurrences of the latter to the
	former and the new hardware integer type conversions now work
	on Irix.

./configure.in
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
./src/H5private.h
./src/H5.c
./test/h5test.c
	Added a wrapper for HDsnprintf() that just calls sprintf() if
	snprintf() isn't available.

./MANIFEST
	Added Paul's new h5toh4 files.

Changes since 19981120
----------------------

./MANIFEST
./test/Makefile.in
./test/shtype.c		[REMOVED]
	Removed shtype.c because it was all commented out.  Besides,
	these tests are done in dtypes.c now anyway.

./test/fillval.c
./test/flush1.c
./test/flush2.c
./test/links.c
./test/mount.c
./test/mtime.c
./test/unlink.c
	The tests that check the HDF5 API use the h5test support
	functions. For one thing, that means that you can specify the
	file driver that thay use by the HDF5_DRIVER environment
	variable. Possible values are:

	    HDF5_DRIVER='sec2'		Use read() and write()
	    HDF5_DRIVER='stdio'		Use fread() and fwrite()
	    HDF5_DRIVER='core'		Use malloc() and free()
	    HDF5_DRIVER='split'		Split meta and raw data
	    HDF5_DRIVER='family N'	Use file families with each
					member being N megabytes (N
					can be fractional, defaults to 
					one).

	Some tests might fail for certain drivers: for instance, the
	mount and link tests fail for the `core' driver because
	they must be able to close and then reopen a file.

	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/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.

	The `long long' type isn't quite as prevalent as we had hoped; 
	there is at least one system that defines `__int64' but not
	`long long'.  Therefore, I've temporarily changed all
	occurrences of `long long' to `long_long' and then #define
	that in H5private.h based on the existence of `long long' or
	`__int64'. This gets rid of some #ifdef's in other parts of the code.
	The semantics of the hdf5 types are:

	   *int8_t	 Exactly one byte
	   *int16_t	 At least two bytes. We favor 32-bit integers over
			 16-bit integers if the 16-bit integer is 4-bytes wide 
			 (Cray)
	   *int32_t	 At least four bytes.
	   *int64_t	 At least eight bytes
	   long_long	 The widest integral integer type

	The H5Smpio.c contains debugging code which is non-portable.

./tools/h5ls.c
	Changed the order native types are detected so we favor the name `int' 
	over `short' or `long' if two of them are the same size.

./config/conclude.in
	Added a rule to make test programs depend on the hdf5 library. This
	fixes a make bug where changing H5detect.c and then running `make
	test' caused H5Tinit.c to not be recompiled and therefore the test
	files are not relinked.

./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

	Added checks for Posix.1g types like `int8_t'.  If not defined

	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 ;-)


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.


Changes since 19981111
----------------------

./INSTALL
	Added instructions about specifying a path for GNU zlib and
	HDF4 headers and library.

	Added comments for each of the tool names.  Added h5toh4 as a
	tool name.

./configure.in
./conigure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
	The config/* scripts get invoked with $CC_BASENAME set the
	base name of the compiler in order to make it easier to handle 
	setting compiler flags for different compilers in a big case
	statement.  For instance, if $CC has the value

	    /usr/local/mpi/bin/mpicc -ansi -64

	then $CC_BASENAME will be `mpicc'.  The $CC_BASENAME is not
	set if $CC is not set.

	Fixed alignment in `configure --help'.

	An include and/or library path can be specified for GNU zlib
	if configure can't find it in normal places.  The "normal"
	means wherever your compiler normally searches, including
	search paths you've added through environment variables like
	CPPFLAGS and LDFLAGS.  The INSTALL file has instructions.

	The `-ljpeg' library is detected.

	If `ssize_t' is not found then a #define is added to
	H5config.h similar to what we already do for `size_t'.

	We detect the hdf5 header file `mfhdf.h' and libraries
	`-lmfhdf' and `-ldf' and if found define the H5TOH4 and
	TESTH5TOH4 Makefile variables.  The user can specify an
	include and/or library path. The INSTALL file has
	instructions.

	The `RUNTEST' variable has been split into `RUNSERIAL' and
	`RUNPARALLEL' because these are different commands.  The
	makefile still uses `RUNTEST', which defaults to the RUNSERIAL 
	value.  The new testpar/Makefile.in sets RUNTEST to the
	RUNPARALLEL value. The default RUNSERIAL value is empty and
	the default RUNPARALLEL value is `mpirun -np 2'.  These can
	both be overridden in the config/* files.  To make the value
	the empty string set it like `RUNPARALLEL=none' in the
	config/* file.

	The new testpar/Makefile is generated from testpar/Makefile.in

./config/commence.in
	Added the RUNSERIAL and RUNPARALLEL makefile definitions.

./src/Makefile.in
	The `H5detect' program is run with RUNSERIAL, which is empty
	on all platforms except intel-osf1 (ASCI/Red)

./config/conclude.in
	Removed the `.c.a:' implicit rule -- we don't use it any more.

./config/BlankForm
./config/alpha-dec
./config/alpha-dec-osf4.0
./config/freebsd2.2.7
./config/hpux10.20

./config/irix64
./config/linux
./config/powerpc-ibm-aix4.2.1.0
./config/rs6000-ibm-aix4.1.4.0
./config/solaris2.5
	All of these files have been updated to hande multiple
	compilers. Most of them assume `cc' if CC is not set. The
	documentation in `BlankForm' has been updated and
	documentation in the other files refer to `BlankForm'.

	The intel-osf1 uses LDFLAGS instead of LIBS to specify the extra
	library search paths.

./examples/Makefile.in
./test/Makefile.in
./tools/Makefile.in
	Simplified by grouping some dependency information together
	more succinctly.

	The tools Makefile.in has been modified to work with the
	`h5toh4' and `testh5toh4' programs.  Until Paul checks these
	in you may have problems compiling.  If so, just create files
	h5toh4.c and testh5toh4.c that contain:

	    #include <stdio.h>
	    int main(int argc, char *argv[]) {
	        fprintf(stderr, "%s: not implemented\n", argv[0]);
		return 1;
	    }

./src/H5public.h
	Removed definition for `ssize_t' since this is now handled by
	configure in H5config.h with a #define.


./MANIFEST
./testpar/Makefile.in	[NEW]
	Added a makefile for parallel tests.  As soon as we get this
	working properly we can remove the other four makefiles in
	that directory and maintain just one.

./test/ragged.c
./src/H5.c
./src/H5private.h

	Reformatted strange-looking comments.

	Removed C++ comments.

	Wrapped long lines.

./examples/h5_attribute.c
./examples/h5_select.c
	Removed inclusion of private headers.

	Changed `uint32' (originally `uint') to `unsigned' because
	`int32' is not exported as part of the API.

./src/H5Fmpio.h
	Removed includes for <sys/types.h> and <sys/stat.h> since
	they're already included by H5private.h.  All system include
	files should be included in H5private.h so we can wrap them
	with appropriate feature macros.

./tools/h5import.c
./tools/h5repart.c
	Included header files like all other programs in that
	directory.

./tools/h5tools.c
	Better type checking for `hsize_t' and `hssize_t'.


Changes since 19981105
----------------------

./configure.in
./acconfig.h
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
	Added checks for functions, structs, constants, and header
	files used in h5ls.c to determine the output width with
	various Windows compilers and Unix variants.

	Added check for <sys/stat.h> and defined
	HAVE_SYS_STAT_H. Included <sys/stat.h> in H5private.h outside
	the Posix.1 #include's section.

./src/H5RA.c
	Less aggressive about failing -- rather returns false, which
	allows type detection to continue.

./src/h5ls.c
	Data types are displayed for datasets and named data types when
	`-v' or `--verbose' is specified on the command-line.  The
	algorithm is a little different than the dumper because we're
	trying to be human-friendly, not necessarily machine-friendly.

	   * Any data type which matches a native C type gets printed
	     something like `native double'.

	   * A floating point type that matches one of the IEEE standard
	     types but not one of the native types gets printed like `IEEE
	     64-bit big-endian float'.

	   * Other floating point values have information about sign bit
	     location; exponent size, location, and bias; and significand
	     size, location, and normalization.

	   * Padding and offsets are displayed for types that have
	     padding (precision != size), including internal padding for
	     some floating point data types.

	   * Non-native integer types are displayed like `32-bit
	     little-endian unsigned integer'.

	   * Compound data types have each member displayed including the
	     member name, byte offset within the struct, dimensions, index
	     permutation, and data type.

	   * String types are displayed like `256-byte null-terminated
	     ASCII string'.

	   * References are displayed like `8-byte unknown reference'
	     until the reference interface stabilizes a little.

	   * All other types including types not yet defined will be
	     printed like `4-byte class-9 unknown'.

	The dimensionality of scalar datasets is printed like `{SCALAR}'
	instead of just `{}'.

	If external raw files are used to store a dataset then the offsets, 
	sizes, and file names of each are printed if `-v' or `--verbose'
	was given on the command-line.

	If an object is found and h5ls can't determine the object type then 
	it still tries to print the number of hard links, the OID, and any
	comment that might be present if `-v' or `--verbose' was specified.

	If the `-d' or `--dump' switch is turned on then ragged arrays will 
	report that the data can only be dumped by dumping the component
	datasets explicitly.  I'm not planning to implement this since
	we're going to eventually change the whole way ragged arrays are
	stored.

	Compound data values do not have the component names displayed by
	default when `-v' or `--verbose' is turned on.  Instead, the names
	can be displayed with `-l' or `--label'.

	The output width is determined by the first rule that applies:

	   * If the `-wN', `-w N' or `--width=N' switch appeared on
	     the command line then use N for the output width.

	   * Query the OS for the tty width in a highly unportable way
	     borrowed from GNU `less' depending on what functions and
	     data structures were found during configuration (if any):
	     _getvideoconfig(), gettextinfo(), _srcsize(), ioctl(),
	     GetConsoleScreenBufferInfo(), struct videoconfig, struct
	     text_info, the TIOCGWINSZ ioctl, the TIOCGETD ioctl.

	   * If the `COLUMNS' environment variable is set then use
	     its value.

	   * Use the value 80.

	Just for kicks, run Mark and Jim's test_vbt and then say `h5ls -dlsv 
	test.vbt'.  You can also try it on the various *.h5 files in the
	test/example directories.

./config/linux
	Removed turning on parallel by default on Robb's macine.


Changes since 19981102
----------------------

./bin/snapshot
	Made same fix as for the release script yesterday.

./src/H5D.c
./src/H5Dprivate.h
./src/H5G.c
./src/H5Gprivate.h
./src/H5Gpublic.h
./src/H5O.c
./src/H5Oprivate.h
./src/H5RA.c
./src/H5RAprivate.h
./src/H5T.c
./src/H5Tprivate.h
	Improved object type checking.  Instead of determining the
	object type by trying to open each of the possible types, we
	keep a table of associations between object type number (like
	H5G_GROUP, H5G_DATASET, H5D_TYPE, and H5D_RAGGED) and an `isa' 
	function that returns true if the object header has the right
	messages to make the object a particular type.  This mechanism 
	also allows specialization of object types by permitting an
	object to satisfy more than one `isa' function.

	Added `isa' functions for groups, datasets, ragged arrays, and 
	committed data types.

./src/H5config.h.in
	Added HAVE_STAT_ST_BLOCKS.  I thought this had already been
	added, but apparently not.

./tools/h5ls.c
	Removed system include files since they're already included by 
	H5private.h and since I wasn't including them portably anyway.

	By default, 1-byte integer types are printed as integer values
	instead of ASCII characters. However, the `-s' or `--string'
	command-line switch causes the data to be interpretted as
	ASCII.  String data types are always printed as character
	data.

	Ragged arrays are now identified as ragged arrays and h5ls
	doesn't descend into the group automatically.  This uses the
	new object type specialization stuff.

./tools/h5tools.c
./tools/h5tools.h
	Added the ability to print 1-byte integer types as either
	ASCII or numeric data instead of always ASCII.  The default is 
	to print as numeric data.

./src/H5Vprivate.h
./src/H5config.h.in	[REGENERATED]
./src/H5private.h
./src/H5public.h
./test/big.c
	Added more configuration stuff for the Win32 environment. Removed all
	the #ifdef WIN32 from the source and replaced them with OS-independent
	stuff.  Specifics follow:

	Check for non-Posix.1 `st_blocks' field in `struct stat' which is used 
	by the big file test to decide if the file system supports holes.  If
	the st_blocks field isn't present then we just skip the test.

	Configure checks for <io.h> <sys/resource.h> <sys/time.h> and
	<winsock.h> and defines HAVE_IO_H, HAVE_SYS_RESOURCE_H,
	HAVE_SYS_TIME_H and HAVE_WINSOCK_H when they're found.

	Configure checks whether both <sys/time.h> and <time.h> can be
	included and defines SYS_TIME_WITH_TIME if so.  Otherwise include only
	<sys/time.h> or <time.h> even if both exist.

	Configure checks sizeof(__int64) and defines SIZEOF___INT64 to the
	result or to zero if __int64 isn't defined.  The source uses `long
	long' in preference to `__int64'.

	Removed null WIN32 definition for `inline' since such a definition
	already exists in H5config.h

	Protected gettimeofday() calls in debugging code with
	HAVE_GETTIMEOFDAY instead of WIN32.

./src/H5F.c

./src/H5Fsec2.c
./src/H5Fstdio.h
./src/H5P.c
./src/H5Tconv.c
./src/H5private.h
	Removed #include of system files from library source files and
	consolodated them into H5private.h where they're protected by various
	configuration macros (most of them were duplicated there already
	anyway).

./test/big.c

./test/links.c
./test/mount.c
./test/mtime.c
./test/overhead.c
./test/ragged.c
./test/shtype.c
./test/unlink.c
	Protected system #include's with #ifdef's from H5config.h.

	Undefined NDEBUG since some of the tests rely on assert() to check
	return values.

	Removed WIN32 definitions for __unused__ since this can be controlled
	by the definition of HAVE_ATTRIBUTE in H5config.h

./test/testhdf5.h
	Removed the CLEAN_CMD definition because we no longer use it.
	Albert's cleanup() functions replaced it.

./test/fillval.c
	Initialized auto hid_t variables to fix warnings in error recovery
	code when data flow analysis is turned on in compilers.

./test/h5tools.c
	Initialized an auto variable to fix a compiler warning.

./test/chunk.c
./test/ragged.c
	The WIN32 had some unsigned variables changed to signed because the
	compiler generates warnings when coercing unsigned to double(?).  I
	changed them back to unsigned because they really are unsigned
	quantities. If this the change was just to shut up extraneous warnings 
	then perhaps a compiler flag can do the same; otherwise if the
	compiler generates bad code then we should supply a patch file instead 
	messing up source code with bug work-arounds.

./src/H5detect.c
	Protected system #include's with #ifdef's from H5config.h thereby
	removing a WIN32.

	If getpwuid() doesn't exist (HAVE_GETPWUID) then we assume that
	`struct passwd' doesn't exist either (we don't really need it in that
	case).

	The H5T_NATIVE_LLONG and H5T_NATIVE_ULLONG are defined in terms of
	`long long' or else `__int64' or else `long' depending on what's
	available.

./src/H5Flow.c
./src/H5Ofill.c
	Added __unused__ to some function arguments that aren't used when
	assertions are turned off.

./src/H5V.c
	Changed an auto variable name in some hand-inlined code to get rid of
	a warning about the variable shadowing a previous auto.

Changes since 19981026
----------------------

./INSTALL
	Updated version number.  Negated information about debugging
	and optimizations.

./RELEASE
	Updated version number. Added a `Changes since the Beta
	Release' section.  Please fill in with anything appropriate.

./README
	Ran bin/release to update the first two lines with the correct 
	version number.

./doc/html/Version.html
	Added comment about rewinding the version number to 1.0 for
	the initial release.

Changes since 19981026
----------------------

./MANIFEST
./test/th5s.h5			[NEW]
./test/th5s.c
	Added a test to make sure that creating a data space with too
	large a rank fails.

	Added a test to make sure that reading a file that has a
	dataset with a space with too large a rank fails.  Actually,
	this one is a little weird: the code that reads the data space 
	message assumes the space is scalar if the message cannot be
	read. Fortunately the layout message fails also, preventing
	the dataset from being opened.  However, since the data type
	message is still visible h5ls will report that the object is a 
	named data type.

./test/space_overflow.c		[NEW]
	This is the little program that makes the th5s.h5 file.

./src/H5A.c
./src/H5R.c
./src/H5Sselect.c
	Updated trace info.

./src/H5Olayout.c
./src/H5Osdspace.c
	Added code to fail if the dimensionality is too large when
	decoding a layout or simple data space message.

./src/H5Oprivate.h
	Redefined H5O_LAYOUT_NDIMS in terms of H5S_MAX_RANK.

./src/H5P.c
./src/H5S.c
	Check for ndims>H5S_MAX_RANK in API function calls, added
	assert to internal functions.

./src/H5V.c
	Changed a `<' to an `<=' in an assert.

./test/flush2.c
	Includes stdlib.h for getenv().

./tools/h5tools.c
	Able to handle up to H5S_MAX_RANK dimensions during output.


Changes since 19981023
----------------------

./MANIFEST
./test/Makefile.in

./doc/html/Chunk_f6.obj		[NEW]
	New documentation for chunking.  It's not quite complete but
	it gives a pretty good idea of some of the issues affecting
	performance.

Changes since 19981021
----------------------

./src/H5I.c
	If we ran out of object ID's (which happens after about 67
	million requests) then we'd wrap back to the first possible ID
	but if we ran out a second time (after ~134 million requests)
	then H5I_register() failed.  Now it continues to wrap as often
	as needed.

	If we wrapped to the beginning of the possible ID's and then
	requested ID's till we got toward the end of the list then
	H5I_register() failed if the last possible ID's were in use.
	The new behavior is to try all possible ID's (not just higher
	ID's) before giving up.


Changes since 19981019
----------------------

./src/H5Fistore.c
	Improved the hash function so it mixes bits better.  This
	results in a few percent improvement in raw data chunk cache
	efficiency because there are fewer collisions.

./test/chunk.c
	Added #define's for chunk preemption `w0' value and number of
	slots in cache.

./src/H5B.c
	Added some more comments to H5B_insert_helper() and
	H5B_remove_helper()  and also point to some additional
	documentation.


Changes since 19981016
----------------------

./src/H5F.c
./src/H5Fpublic.h
	Added H5Freopen() as documented in earlier e-mails.  This is
	really just a wrapper around H5F_new().


Changes since 19981014
----------------------

./bin/trace
./src/H5.c
./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
	Added a `scope' argument to H5Fflush() which should be either
	H5F_SCOPE_LOCAL or H5F_SCOPE_GLOBAL and determines which files 
	are flushed (just the specified file or the entire virtual
	file).

./src/H5F.c
	Added reference counts to the H5F_t struct so we get the
	correct behavior between H5Funmount() and H5Fclose().

./src/H5O.c
	Fixed a memory leak that happens during error handling.

./test/cmpd_dset.c
./test/unlink.c
	Fixed a memory leak.

./test/mount.c
	Enabled the H5Fclose() test.


Changes since 19981013
----------------------

./src/H5.c
	Fixed a signed vs. unsigned comparison.

./src/H5D.c
	Setting a fill value of all zeros will cause the fill value to
	be written to the dataset instead of relying on the low-level
	file driver initializing unwritten areas with zero.

./src/H5D.c
./src/H5F.c
./src/H5Fprivate.h
./src/H5G.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5O.c
./src/H5T.c
	More file mounting stuff.

./src/H5I.c
	Fixed a bug where trying to close an invalid object id caused
	a core dump.  For instance, H5Gclose(-1).

./MANIFEST
./test/Makefile.in
./test/mount.c		[NEW]
	Mounting tests.

./src/H5R.c
	Fixed a couple (herr_t)NULL casts.

Changes since 19981008
----------------------

./src/H5F.c
./src/H5Fprivate.h
./src/H5G.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gpublic.h
./test/istore.c
./test/tstab.c
	Removed CWG functionality.
	
./tools/Makefile.in
	Added `_test' where I added `test' last week.  Maybe now the
	snapshots will start up again...


Changes since 19981002
----------------------

./doc/html/H5.format.html
./src/H5HG.c
	Fixed a bug in the global heap that caused H5HG_read() to
	write past the end of the buffer in certain cases.

./test/big.c
	The test is skipped if hdf5 was configured with
	`--disable-hsizet'.

./src/H5Ofill.c
	Data type conversions are implemented for the fill value.

./src/H5.c
	Tracing prints one of H5P_FILE_CREATE, H5P_FILE_ACCESS,
	H5P_DATASET_CREATE, H5P_DATASET_XFER, or H5P_MOUNT instead of
	the more cryptic H5I_TEMPLATE_* constants.

./src/H5D.c
	Removed prototype for H5D_find_name().

./src/H5I.c
	The GROUP_MASK and ID_MASK are both calculated from GROUP_BITS 
	instead of being set by hand.

	We don't use the sign bit of hid_t; all valid hid_t values are 
	positive so we can say things like `if ((file=H5Fopen(...))<0)'.

	Changed `(int)pow(2.0,x)' to `1<<x' so we don't have to worry
	about rounding.

	Fixed H5I_get_type() so it doesn't always fail an assertion.

./src/H5E.c
./src/H5Epublic.h
	Added minor error H5E_MOUNT

./src/H5F.c
./src/H5Fprivate.h
	Added H5Fmount() and H5Funmount().  Mounting and unmounting
	works as documented but some of the other things aren't
	implemented yet, the biggest being current working groups
	always acting on the root of the mount tree, and H5Fclose()
	closing the entire tree.  The rest of the stuff will be added
	shortly...

./src/H5P.c
./src/H5Ppublic.h
	Added the H5P_MOUNT property list but haven't implemented any
	particular properties for it yet.

./src/H5Gstab.c
	Hard links across files return an error instead of failing an
	assertion.




Changes since 19981005
----------------------

./src/H5D.c
	Fill values are working for contiguous datasets now except
	there are two things that need more support from the data
	space layer, specifically the ability to form a selection from 
	the difference of two selections.  They are (1) extending an
	external contiguous dataset, (2) optimization by delaying the
	fill until after the first H5Dwrite().

	Renamed H5D_allocate() to H5D_init_storage() since allocation
	is only part of the story. Added a data space argument so it
	doesn't have to query the space from the object header -- the
	space is always available in the caller anyway.

	Removed `#ifdef HAVE_PARALLEL' from a few places where it
	wasn't necessary.  We don't need it around code that doesn't
	compile anything from mpi.h or mpio.h.

./src/H5Fistore.c
	Uncommented H5F_istore_alloc() for non-parallel and moved the
	`#ifdef HAVE_PARALLEL' just around Kim's barrier.

./src/H5Fmpio.c
	Wrapped a couple long lines.

	Got rid of two signed vs. unsigned comparison warnings.

./MANIFEST
./test/Makefile.in
./test/fillval.c	[NEW]
	Added tests for fill values.  The contiguous dataset extend
	test is disabled until H5S_SELECT_DIFF is implemented.

./tools/Makefile.in
	Fixed a bug where `make test' didn't build the executables
	first.  This should cause the snapshots to start up again.

./Makefile.in
	Changed to build in `test' directory before `tools'
	directory. We want the library tests to pass before we even
	start considering the tools.  You can still build and/or test
	the tools independent of the library tests passing.

Changes since 19981001
----------------------

./src/H5D.c
./src/H5Fistore.c
./src/H5Fprivate.h
	Fixed a couple things for parallel hdf5 that I broke with the
	last checkin.

./src/H5Ofill.c
	If no fill value is specified it isn't added to the object
	header.

./tools/h5ls.c
	Added a line-feed after `Unknown object' is printed.

./tools/h5tools.c
	Fixed printing of scalar values.  Need to still track down a
	failed assertion when H5Sselect_hyperslab() is called with a
	zero size....

./src/H5Omtime.c

./src/H5Sall.c
./src/H5Shyper.c
./src/H5Spoint.c
./src/H5Sprivate.h
	Added more type checking for the data transfer property list
	passed to these functions.

./src/H5D.c
	Added a dataset transfer property list as an argument to
	H5D_allocate() for the parallel version in order to pass split 
	ratios down to H5F_istore_lock().  Eventually we won't need
	the split ratios for H5D_allocate() because we'll build a
	completely full B-tree from the leaves up, but it might be
	useful to have other transfer properties at that level
	anyway.  I always caled H5D_allocate() with &H5D_dflt_xfer.

	The default number of slots is 521 and the default maximum
	size is 1MB.

./src/H5Fistore.c
./src/H5Fprivate.h
	Finished optimizations.  The cache is now a hash and a linked
	list instead of an array.  The cpu time on my machine for
	H5F_istore_lock() has been cut by 60% and H5F_istore_unlock() by
	35%.

Changes since 19980911
----------------------

This checkin is to fix a couple bugs for Jim Reus.  Some features are
not fully implemented but it shouldn't break anything.

./config/conclude.in
./test/Makefile.in
	`make clean' removes object files from the test directory as
	well as a couple more *.h5 temp files.

./config/hpux9.03		[NEW]

./src/H5Fistore.c
./src/H5Fprivate.h
	Experimental optimizations, disabled by default.

./src/H5Fprivate.h
	Default low-level driver was changed to H5F_LOW_SEC instead of 
	H5F_LOW_STDIO because the sec2 driver is much easier to debug.

./src/H5Fsplit.c
./src/H5G.c
./src/H5Z.c
	Changed a couple return statements to HRETURN.

./src/H5Odtype.c
	Removed a check for nested compound data types from back when
	they weren't implemented that raised an error.

./tools/h5tools.c
	Increased temp buffer sizes and added a check for buffer
	overflow so we fail an assertion (hopefully).  This really
	needs to be fixed sometime.

	Added support for printing H5T_STRING data types.

	

Changes since 19980910
----------------------

./MANIFEST
	Removed duplicate Ragged.html

./doc/src/Glossary.html

./test/tfile.c
	Changed H5Fget_create_template() and H5Fget_access_template()

Changes since 19980904
----------------------

./MANIFEST
./bin/release
./bin/snapshot
	The format of the MANIFEST file has been relaxed -- comments
	and blank lines should no longer confuse the tools that use
	it.

	As before, this file should contain a list of *all* files that
	are part of HDF5, which means all files which are managed by
	CVS/SVF.  However, files can be marked so they're not part of
	a release by adding _DO_NOT_DISTRIBUTE_ after the file name.

	I've removed all the *.obj files from the distribution by
	adding _DO_NOT_DISTRIBUTE_ after their names.  I also removed
	the old white-papers that might not apply to the current
	version of the library and documentation about chunking
	performance since it's wrong now that chunk caching is
	implemented. Everyone please check the files you're
	responsible for to make sure that they should really be part
	of a release.

	To get a list of all files use
	   grep '^\.' MANIFEST | cut -f1

	To get a list of files for distribution use:
	   grep '^\.' MANIFEST | grep -v _DO_NOT_DISTRIBUTE_

	(These commands assume tabs in the MANIFEST file.  If the file 
	might contain spaces then run it through `unexpand' or `tr'
	first).

./configure.in
./configure
./src/H5config.h.in
./test/ragged.c
	Check for sigaction().

./test/Makefile.in
	The `clean' target removes the timing tests.

./bin/checkposix
	Got rid of complaints about some obvious things.

./doc/html/H5.api.html
./doc/html/RM_H5F.html
./src/H5F.c
./src/H5Fpublic.h
./test/tfile.c
	Changed H5Fget_create_template() and H5Fget_access_template()
	to H5Fget_create_plist() and H5Fget_access_plist() since that
	conforms better to lots of other names.

./src/H5Iprivate.h
./src/H5Ipublic.h
./src/H5I.c
	Changed the scope of some symbols to be more local.

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

Changes since 19980901
----------------------

./test/dtypes.c
	Got rid of one of some of the `increases alignment' warnings.

./test/tselect.c
	Got rid of an unused variable.

Changes since 19980931
----------------------

./test/cmpd_dset.c
	Uncommented the last test again and there are still bugs.

Changes since 19980831
----------------------

./Makefile.in
	Running `make distclean' will not fail if one of the
	subdirectories has already been cleaned.

./config/BlankForm
./config/irix5.3
	Cleaned it up more.  Added better support/documentation for
	systems that have more than one compiler.

./config/alpha-dec-osf4.0	[NEW]
	Added a new config file as a result of testing on Jim Reus's
	machine.

./test/chunk.c
	Scaled down the testing range so we can actually run it
	interactively.

./tools/h5import.c
	Included <unistd.h> to get rid of warning for close().

./src/H5detect.c
	Seg-faults on Linux for some reason when NDEBUG is defined, so
	I just undef it at the top of the source.

./test/big.c
	Added a fflush().

./tools/h5ls.c
	The `-d' flag now works even when `-v' isn't specified.

./examples/h5_chunk_read.c
./examples/h5_compound.c
./examples/h5_extend_write.c
./examples/h5_group.c
./examples/h5_read.c
./examples/h5_write.c
	Indented according to hdf5 standards.
	
	Fixed compiler warnings


Changes since 19980828
----------------------

./RELEASE
	Updated with important changes I made since the second beta.

./src/H5A.c
./src/H5D.c
./src/H5Dprivate.h
./src/H5G.c
./src/H5Gprivate.h
./src/H5R.c
./src/H5Rprivate.h
./src/H5T.c
./src/H5Tprivate.h
	Any API function that used to take an `hid_t loc_id' followed
	by a `const char *name' can now take any type of object for
	the loc_id as long as the object is somehow associated with a
	file. Internally, H5G_loc() was modified to return an
	H5G_entry_t* instead of an H5G_t* so it's more general.

	Among other things, this allows one to retrieve information
	about an object like a named type or dataset without knowing
	the name of the type or dataset:

	    int
	    get_nlinks (hid_t obj)
	    {
	        H5G_stat_t	sb;
		if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1;
		return sb.nlink;
	    }

./test/gheap.c
./test/istore.c
	These files needed a couple of changes because they call some
	of the internal functions whose H5G_t arguments changed to
	H5G_entry_t.

./src/H5A.c
	Got rid of all the switch statements for getting symbol table
	entries for varous objects and replaced them with a call to
	H5G_loc() allowing attributes to automatically apply to any
	type of object that belongs to a file.

./test/Makefile.in
	Moved the ragged array tests from the normal list of tests to
	the `make timings' target.

./test/ragged.c
	Added rewrite tests -- rewrite the rows of a dataset changing
	the number of rows and the length of each row.

./test/mtime.c
	Added a test that checks that H5Gstat() can be called with a
	dataset as the first argument.

./src/H5S.c
	Added #ifdef HAVE_PARALLEL around code to check for the
	HDF5_MPI_OPT_TYPES environment variable because the global
	variable that gets set is #ifdef'd.

./bin/release
	bzip2 uses .bz2 as the file extension.
		    

Changes since 19980827
----------------------

./src/H5G.c
	Fixed a link count on groups.  Groups were always created with 
	a link count of zero instead of one.

./src/H5Gpublic.h
	Added H5G_NTYPES so applications can easily declare arrays
	which are indexed by object type.

./src/H5O.c
	Calling `H5O_link(&ent,0)' will succeed when the file is open
	for read only because it's the only way to get the object's
	current link count.

./tools/h5ls.c
	Can take non-group object names on the command line (and
	multiple objects).  Reorganized to be more extendible. The
	link count is displayed for `-v'.

./src/H5F.c
	Dumping of cache statistics is controlled by only the
	HDF5_DEBUG environment variable and not the H5F_ACC_DEBUG flag 
	for H5Fopen() and H5Fcreate() since this makes it similar to
	the other debugging options.

./src/H5R.c
./test/ragged.c
./test/Makefile.in
	Tests pass but still a little work left to be done.


Changes since 19980825
----------------------

./MANIFEST
./src/H5R.c		[NEW]
./src/H5Rprivate.h	[NEW]
./src/H5Rpublic.h	[NEW]
./src/Makefile.in
./src/hdf5.h
./test/ragged.c		[NEW]
	Preliminary support for 2d ragged arrays for Mark Miller and
	Jim Reus.  Not fully implemented yet. The test is not actually 
	part of `make test' because we still have some memory problems.

./src/H5E.c
./src/H5Epublic.h
	Added H5E_RAGGED as a major error number.

./bin/release
	Checks the MANIFEST file against `svf ls' on systems that have 
	it.

./bin/trace
	Fixed a bug that caused arguments of type `void *x[]' to not
	be handled.

./src/H5.c
	Removed unused variables and changed a couple types to
	fix compiler warnings.

	Added tracing support for ragged array object ID's and arrays
	of pointers.

./src/H5D.c
	H5Dcreate() will complain if either of the property lists are
	invalid (instead of using the default).

./src/H5D.c
./src/H5Dprivate.h
	Split H5Dget_space() into an API and internal function so it
	can be called from the new ragged array layer.

./src/H5Fistore.c
	Fixed warnings about unsigned vs. signed comparisons.

./src/H5Flow.c
	Fixed a warning about a variable being shadowed in the MPI-IO
	stuff.

./src/H5Iprivate.h
./src/H5Ipublic.h
	Added the H5_RAGGED atom group.

./src/H5Shyper.c
	Fixed some freeing-free-memory errors that resulted when
	certain arrays were freed but the pointers were left in the
	data structures.  I simply set the pointers to null after they 
	were freed.

./src/H5Sprivate.h
./src/H5Sselect.c
	Split the H5Sselect_hyperslab() function into an API and a
	private function so it could be called from the ragged array
	layer.

	Added H5S_SEL_ERROR and H5S_SEL_N to the switch statements to
	get rid or compiler warnings.

./src/H5Tconv.c
	Removed a misleading comment.

./test/bittests.c
	Fixed a warning about a printf().

./test/cmpd_dset.c
	Fixed warnings about unused variables because of test #11
	being commented out.

./bin/trace
	Shortened the right margin for the output to allow room for
	the `);' at the end of the TRACE() macros.

Changes since 19980824
----------------------

	Undocumented changes while at Livermore.

Changes since 19980818
----------------------

./src/H5.c
	Fixed an argument promotion bug in HDfprintf()

./src/H5Fistore.c
	Fixed a array bounds read error.

./src/H5HG.c
	Fixed uninitialized (but unused) data appearing in the hdf5
	file, a potential security problem.

./src/H5T.c
./src/H5Tpublic.h
	Added new data types for hdf5 types: H5T_NATIVE_HSIZE,
	H5T_NATIVE_HSSIZE, H5T_NATIVE_HERR, and H5T_NATIVE_HBOOL. I
	did not add H5T_NATIVE_HID since I couldn't think of a reason
	that it would be stored in a file anyway.

Changes since 19980814
----------------------

./src/H5Fistore.c
	Fixed a bug that caused the wrong number of chunk offsets to
	be read or written from the file.

./src/H5Z.c
	Fixed a memory bug.

./test/dtypes.c
	Removed redundant tests.

./bin/snapshot
	Removed Perl code from a shell script. Oops :-)

./src/H5D.c
	Removed cvs merge conflicts.

./src/H5Omtime.c
	Fixed a typo in the Irix5.3 code.

./src/H5S.c
	Fixed a memory leak.

./src/H5Shyper.c
	Fixed a bad call to malloc() that didn't allocate enough
	memory. Reordered a comparison to eliminate an array bounds
	read error.

Changes since 19980813
----------------------

./src/H5G.c
./src/H5Gpublic.h
./test/links.c
	Fixed a bug in H5Gstat() that caused the wrong information to
	be returned sometimes.  Added check for named data types.

./test/extend.c
./test/links.c
./test/mtime.c
	Added `all tests passed' messages.

Changes since 19980810
----------------------

./MANIFEST
./src/H5Ssimp.c		[REMOVED]
./src/Makefile.in
	Removed H5Ssimp.c since it was no longer used.

./bin/snapshot
	Fixed a few minor things to make it work better.

./src/H5D.c
	Cleaned up H5D_read() and H5D_write() by combining some code
	in each. Added timing calls around the data space calls when
	H5S_DEBUG is defined.

./src/H5S.c
./src/H5Sall.c
./src/H5Shyper.c
./src/H5Spoint.c
./src/H5Sprivate.h
	Changed H5S_find() so it returns a table entry again instead
	of copying the data into a caller-supplied buffer.  This
	allows the timers to be stored in the table and updated by the 
	caller.  Added H5S_register() to register new table entries
	and added entry creation to all the H5S selection
	methods. Also changed lots of global functions to static
	functions.

./src/H5Fistore.c
	Fixed a memory bug in the raw data cache.

Changes since 19980806
----------------------

./doc/html/Datatypes.html
./doc/html/H5.format.html
./src/H5.c
./src/H5Odtype.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tpublic.h
./test/dtypes.c
	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

./bin/snapshot
	Better `diff' of two releases.

	Skip release if `make _test' fails.

Changes since 19980806
----------------------

./config/solaris2.5
	Hopefully set up now so it honors the CC and CFLAGS variables
	and understands solaris cc flags.

./test/big.c
	Checks to see if creating lots of large sparse files exceeds
	the user disk quota and skips the test.  It also checks that
	we can actually open ~64 files at once.

./doc/html/Files.html
./src/H5A.c
./src/H5Aprivate.h
./src/H5F.c
./src/H5Fpublic.h
	Added the H5Fflush() function which takes any object as an
	argument as long as the object is in some way associated with
	a file.  This required an H5A_entof()

./src/H5.c
./src/H5Flow.c
	The `%a' format of HDfprintf() now allows a field width and
	justification flag etc, like the other formats.  The old
	H5F_addr_print() was recoded to call HDfprintf() instead of
	vice versa.



Changes since 19980805
----------------------

./MANIFEST
	Replaced Compression.html with Filters.html

./doc/html/Filters.html
./src/H5Ocomp.c
./src/H5P.c
./src/H5Ppublic.h
./src/H5Z.c
./src/H5Zprivate.h
	Added two extra arguments to H5Pget_filter() in order to
	retrieve the filter name.  The name is the name registered for 
	the filter with H5Zregister(), but if the dataset creation
	property originally came from an existing file then the name
	is that which is stored in the file.

./tools/h5ls.c
	The `-v' option now prints the names of the filters.

./src/H5B.c
./src/H5Fistore.c
./src/H5O.c
./src/H5Oefl.c
./src/H5Oprivate.h
./src/H5P.c
	Plugged a memory leak.

./src/H5MMprivate.h
	H5MM_malloc(0) and H5MM_calloc(0) actually allocate a single
	byte in order to be sure that we get a valid pointer.

./src/H5S.c
./src/H5Sselect.c
	Fixed pointer->integer conversions in error return values in
	three places.

Changes since 19980731
----------------------

./bin/release
	Added ./Makefile to the distribution again -- it got lost in
	the changes last week although it isn't all that important a
	file since it gets clobbered by configure anyway.

./bin/trace
./doc/html/Filters.html
./doc/html/H5.format.html
./doc/html/H5.user.html
./src/H5.c
./src/H5D.c
./src/H5Dprivate.h
./src/H5E.c
./src/H5Epublic.h
./src/H5Farray.c
./src/H5Fistore.c
./src/H5Fprivate.h
./src/H5O.c
./src/H5Ocomp.c
./src/H5Oprivate.h
./src/H5P.c
./src/H5Ppublic.h
./src/H5Sall.c
./src/H5Shyper.c
./src/H5Spoint.c
./src/H5Sprivate.h
./src/H5Ssimp.c
./src/H5Z.c
./src/H5Zprivate.h
./src/H5Zpublic.h
./src/hdf5.h
./test/dsets.c
./tools/h5ls.c
	Added the data filter pipeline, a generalization of the
	compression stuff which allows things like checksums,
	encryption, compression, performance monitoring, etc.  See
	./doc/html/Filters.html for details -- it replaces the
	Compression.html doc.

./src/H5T.c
	Cleaned up debugging output.

./config/linux
	Added checks for egcs and pgcc and changed optimization flags
	for the compilers.

./src/H5G.c
./tools/h5dump.c
	Fixed compiler warnings in these files and others.

./configure.in
./src/H5private.h
./test/mtime.c
	Added a check for difftime() and defined HDdifftime() to do
	something else on systems that don't have difftime().

Changes since 19980730
----------------------

./bin/release
	Simplified greatly.  When run from the top of the hdf5 source
	tree with no arguments a new tar file is created in the
	`releases' directory.  When given one or more of the words
	`tar', `compress', `gzip', or `bzip2' each type of archive is
	created.  The name of the releases directory can be changed
	with the `-d DIR' switch.

./bin/h5vers
	Fixed a bug that caused `h5vers -i' to fail with a usage
	message.  The new behavior is the same as `h5vers -i release'
	which increments the release number.

./bin/snapshot
	A shell script intended to be run nightly from cron which
	compares the current version of hdf5 against the previous
	version.  If there are differences it creates a tar file in an 
	ftp directory, increments the hdf5 release number, and commits 
	the changes back into the cvs repository.  The name of the ftp 
	directory in which to place the release can be given on the
	command line (default /hdf3/ftp/pub/outgoing/hdf5/snapshots).
	The CVSROOT environment variable must be set.


Changes since 19980729
----------------------

./MANIFEST
./test/Makefile.in
./test/mtime.c		[NEW]
	Test for the modification time message.

./src/H5AC.c
./src/H5Fistore.c
	Turned off printing of statistics on H5close() if H5AC_DEBUG
	isn't defined.

Changes since 19980724
----------------------

./MANIFEST
./doc/html/H5.format.html
./src/H5O.c
./src/H5Oprivate.h
./src/H5Omtime.c	[NEW]
./src/H5private.h
./src/Makefile.in
	Added the modification time message.  If an object header has
	this message then it's value is updated with the current time
	whenever anything changes in the object header.

./acconfig.h
./configure.in
	Alas, there seems to be no standard way to convert a string
	time like 19980727122800 in UTC to a time_t since mktime()
	only converts local times to time_t.  So I've modified the
	configuration to check for various ways of getting the time
	zone information:

	   * Added checks for the `tm_gmtoff' field of `struct tm'.
	   * Added a check for the `timezone' global variable.
	   * Added a check for `struct timezone'.
	   * Added a check for BSDgettimeofday().
	   * Added a check for gettimeofday() although it doesn't
	     actually set the timezone argument on some systems.
	   * Added a check to see if `tm_zone' is a member of `struct tm'.
	   * Added a check to see if `tzname' is a global variable.
	   * Added a check to see if `struct tm' is defined in time.h
	     or sys/time.h.

	It's not difficult to get the right UTC modification message
	into the object header, but some systems might have problems
	getting the right time back out (Irix64 is one) and those
	systems will report zero for the H5G_stat_t.mtime from an
	H5Gstat() call as if the mtime message isn't even present.  It 
	will, however, continue to be updated as normal.

./src/H5G.c
./src/H5Gpublic.h
	The H5G_stat_t struct now contains an `mtime' field which will 
	hold the object modification time.  If the object has no
	object modification time then the `mtime' will be initialized
	to zero.

	Fixed a bug in H5G_stat() that caused the `objno' field of the 
	H5G_stat_t to be set incorrectly on some machines.

./src/H5D.c
	Writing to external datasets fail if the hdf5 file is not open 
	for writing.

	A modification time message is added to the dataset object
	header when it's created and H5O_touch() is called from
	H5D_write() to update that message.

./src/H5T.c
	Fixed a bug in H5Tget_member_dims() that caused a segmentation
	fault if one of the output array arguments was the null
	pointer.

	Relaxed the member dimension checking in H5Tinsert_array() so
	it can also be used for scalar members.

./test/Makefile.in
	Added additional file names to the `mostlyclean' target.

./tools/h5dump.c
./tools/h5tools.h
	Increased the temporary buffer size to 1MB.

	Added support for printing compound data types with array
	members.

	When printing H5T_NATIVE_CHAR and H5T_NATIVE_UCHAR we escape
	double quote characters.

./tools/h5ls.c
	Changed the output format a little because we were starting to 
	get too much info to fit on a line.  Without `--verbose' each
	object occupies one line of output.  Otherwise, additional
	information is printed below the object name: object file
	address, comment, and modification time.  If `--dump' is given 
	then the data is printed after the other information.

./test/cmpd_dset.c
	Changed the way the dataset is initialized to be more uniform.

Changes since 19980723
----------------------

./tools/h5dump.c
./tools/h5ls.c
./tools/h5tools.h
	Able to handle compound data types now.  Moved code that
	chooses memory data type based on file data type from h5ls to
	libh5tools.a(h5dump.o)

Changes since 19980722
----------------------

./src/H5A.c
./src/H5Apublic.h
./test/tattr.c
	Switched the order of the second and third argument of
	H5Aget_name() to make it consistent with other functions that
	take buffers and buffer sizes.

./src/H5G.c
./src/H5Gpublic.h
./src/H5Gprivate.h
	The H5Gget_comment() function returns the size of the comment
	including the null terminator.  If the object has no comment
	then zero is returned.  If an error occurs then a negative
	value is returned.

./MANIFEST
./tools/Makefile.in
./tools/h5tools.h	[NEW]
./tools/h5dump.c	[NEW]
	Created a library for printing values of datasets in a way
	that looks nice.  It's not done yet, but I needed it for
	debugging the contents of files from Jim Reus.

./tools/h5ls.c
	Added the `-d' and `--dump' options which cause the contents
	of a dataset to be printed.  Added `-w N' and `--width=N'
	options to control how wide the raw data output should be. If
	you want single-column output then say `-w1'.

	Printing dataset values can now handle datasets of any integer 
	or floating point atomic type.  As a special case, integers
	which are one byte wide are treated a character strings for
	now.

	Sample output:
	    $ h5ls --dump --width=60 banana.hdf
	    ARCHIVE                   0:0:0:744            Dataset {52/Inf}
		Data:

Changes since 19980722
----------------------

./src/H5.c
	Handle hid_t of type H5_TEMPBUF, arguments usually called tbuf_id.

	Added array tracing where the array rank is stored in a simple 
	data space.  Just use the name of the data space argument when 
	declaring the array argument:

	    herr_t
	    H5Sselect_hyperslab (hid_t space_id, H5S_seloper_t op,
				 const hssize_t start[/*space_id*/],
				 const hsize_t _stride[/*space_id*/],
				 const hsize_t count[/*space_id*/],
				 const hsize_t _block[/*space_id*/])

	and when the program runs you'll see array values printed:

	    H5Sselect_hyperslab(space=218103813, op=H5S_SELECT_SET,
                                start=0xbfffef4c {0}, _stride=NULL,
                                count=0xbfffef44 {64}, 
				_block=NULL) = SUCCEED;

	Added more symbolic data types to the tracing output.

./src/H5A.c
./src/H5Apublic.h
./src/H5D.c
./src/H5Dpublic.h
./src/H5F.c
./src/H5Fpublic.h

./src/H5Spoint.c
./src/H5Spublic.h
./src/H5Sselect.c
./src/H5Ssimp.c
./src/H5TB.c
./src/H5V.c
	Changed some API argument names to be more consistent with
	other API functions and to produce better tracing output.
	Reformatted some long lines. Indented printf statements.

./tools/h5ls.c
	Fixed warnings about unsigned vs. signed comparisons.

Changes since 19980721
----------------------

./tools/h5ls.c
	If the dataset is of type H5T_NATIVE_CHAR then we print the
	value as a string.  This is temporary -- I plan to add better
	control of this later but needed something now for debugging.

./src/H5Fistore.c
	Squashed a bug in the chunk caching code that caused the wrong
	chunk to be returned.

./bin/trace
./src/H5.c
	Added support for printing values of array arguments when the
	size of the array is supplied by some previous argument.  You
	must declare the argument as an array in order for the
	automatic tracing stuff to work.  For instance, the third
	argument of H5Pset_chunk() is an array whose size is
	determined by the second argument `ndims'.  Here's how you
	should declare it:

	    herr_t
	    H5Pset_chunk(hid_t plist_id, intn rank, hsize_t dims[/*rank*/])

	The comment inside the `[]' is the name of some previous
	integer argument (int, unsigned, size_t, ssize_t, hsize_t,
	hssize_t).  The trace output will look something like:

	    H5Pset_chunk(plist=1234567, rank=2, dims=0x112233 {11, 22})

	Changed tracing so that data types are printed out
	symbolically when possible.

	Changed tracing so data type initializations are not printed.
	This used to be confusing because lots of H5Tcopy() and
	H5Tregister...() calls showed up before the applications first 
	explicit API call.

./src/H5Ipublic.h
	Changed the file atom group from zero to one so printing of
	atoms during tracing is more consistent -- they're all big
	numbers now.

./src/H5A.c
./src/H5E.c
./src/H5F.c
./src/H5G.c
./src/H5Sselect.c
./src/H5T.c
./src/H5TB.c
./src/H5Z.c
	Accidently modified these when working on the tracing, but
	nothing should have changed.

./src/H5P.c
	Changed the definition of H5Pset_chunk() for tracing.

./src/H5S.c
./src/H5Spublic.h
	Changed the definitions of H5Sset_extent_simple() and
	H5Screate_simple() for tracing.  Changed the FUNC_ENTER() name 
	for H5Screate_simple() so tracing shows the correct name.


Changes since 19980720
----------------------

./test/dtypes.c
	We try to detect whether floating point overflow generates a
	SIGFPE and if it does we don't test overflow cases.

./test/H5Sprivate.h
./test/H5S.c
./test/H5Oattr.c
	Added an H5S_debug() which is called from H5O_attr_debug() and 
	which has a switch statement to handle the various data type
	messages.

Changes since 19980720
----------------------

./src/H5Gpublic.h
./src/H5Gprivate.h
./src/H5G.c
./test/dsets.c
./doc/html/Groups.html
	Added the H5Gset_comment() and H5Gget_comment() functions
	described in an earlier e-mail.

./src/H5.c
	Fixed a bug in the tracing code that caused certain data space 
	enum types to not be printed.  Nested case statements can get
	confusing to the eyes!

./tools/h5ls.c
	Prints the first 50 bytes or so of object comments.

Changes since 19980720
----------------------

./doc/html/H5.format.html
./src/H5Oattr.c
./src/H5Odtype.c
./src/H5Oefl.c
./src/H5Olayout.c
./src/H5Osdspace.c
./src/H5Oshared.c
	Added version numbers to some object header messages so we can 
	update them easier in the future.  The library currently just
	gives up if the version numbers don't match, but in the future 
	the library could handle multiple versions of a message.

./test/testhdf5.c
	Removed an argument from the H5version() call that I missed
	last time.

Changes since 19980720
----------------------

./bin/release
	The archive names have only three parts to a version number.
	Instead of `hdf5-1.2.3d.tar.gz' they will be named like
	`hdf5-1.2.3.tar.gz'.

./src/H5public.h
./src/H5.c
	Dropped the patch level from the version number.  The version
	number is now a major number, a minor number, and a release
	number.

./doc/html/Version.html
	Updated to get rid of patch numbers.

./tools/h5repart.c
	Added a `-V' flag like for `h5ls' that prints the version number.

Changes since 19980720
----------------------

./doc/html/H5.format.html
./src/H5F.c
./src/H5Gprivate.h
./src/H5Oshared.c
	Added file alignment fields: the boot block has an extra
	reserved address field.  The symbol table entry scratch pad
	space was reduced from 24 bytes to 16 bytes.  The index
	permutation was moved earlier in the data type message for
	compound data types and extra padding was added.  Four bytes
	of padding was added to the shared message format.

Changes since 19980715
----------------------

./doc/html/H5.format.html
./src/H5Gent.c
./src/H5Gprivate.h
./src/H5Oattr.c
./src/H5Oprivate.h
./src/H5Oshared.c
./src/H5HG.c
./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
	machines where it's the same size as `double' to get rid of
	compiler warnings.

./doc/html/Big.html
	Fixed a couple typos.

Changes since 19980715
----------------------

./src/H5Flow.c
./src/H5Fprivate.h
./src/H5Fsplit.c
	Changed the allocation size request from `size_t' to `hsize_t'
	because it was overflowing for the `big' test.

./src/H5detect.c
	If `long double' and `double' are the same size then we define 
	H5T_NATIVE_LDOUBLE to be the same as H5T_NATIVE_DOUBLE.
	Similarly for `long' vs. `long long' and `unsigned long' vs.
	`unsigned long long'.

./test/Makefile.in
	Added `big' to the list of tests to normally run.

./test/big.c
	Added a check to see if the file system supports holes and if
	it doesn't then the test is skipped.

./RELEASE
	Added a couple minor details details about API tracing and
	symbolic links.

./src/H5public.h
	Added comments about the use of hbool_t. Fixed a comment
	spelling error.

./test/testhdf5.h
	Changed the way the version number is printed.  The old method 
	was `hdf5-1.2.3d' and the new method is `hdf5 version 1.2
	release 3'

./tools/h5ls.c
	Only prints the max dimension if it differs from the current
	dimension or if verbose mode is enabled.  Added switches `-?',
	`-h', and `--help' to print a usage message.  Added switches
	`-v' and `--verbose' to generate more verbose output.  Added
	switches `-V' and `--version' to print the version number and
	exit.  The version number is printed like: This is h5ls
	version 1.0 release 24'

./bin/h5vers	[NEW]
	This script prints, sets, and/or increments the hdf5 version
	number. It can be run from the top directory or any of the
	child directories like src, tools, test, etc. Some examples:

	  $ h5vers				# Display current version
	  1.0.24

	  $ h5vers -v
	  version 1.0 release 24		# Display current version.

	  $ h5vers -s 5.2.8			# Set version and display
	  5.2.8

	  $ h5vers -s 2.1
	  2.1.0

	  $ h5vers -s hdf5-1.0.24a.tar.bz2
	  1.0.24

	  $ h5vers -s 'version 2.0 release 8'
	  2.0.8

	  $ h5vers -s 'junk 22 junk 33 more junk 66 and 99 junk'
	  33.66.99

	  $ h5vers -i major			# Increment from 1.0.24
	  2.0.0

	  $ h5vers -i minor			# Increment from 1.0.24
	  1.1.0

	  $ h5vers -i release			# Increment from 1.0.24
	  1.0.25

	  $ h5vers ~/hdf5/src/H5public.h	# Use an alternate file
	  1.0.24

./bin/checkapi		[NEW]
	Run from the src directory with arguments H5[A-Z]*.c and it
	will print the locations of each place where an API function
	was called from within the library.  Use it as the compile or
	grep command under Emacs and you can C-x ` through the list.

./bin/debug-ohdr	[NEW]
	Keeps track of H5O_open() and H5O_close() debugging messages
	and lists the file addresses of the object headers that are
	opened but never closed.  You must enable the `o' debugging at 
	configuration time and pipe stderr into this script.

./bin/errors
	Added a note to indicate that this script no longer works
	because of changes in the HRETURN_ERROR() and HGOTO_ERROR()
	macros.

./bin/iostats		[NEW]
	Watches output from the Linux strace program and accumulates
	statistics about low-level access to an hdf5 file.  The output 
	is a list of 2d data points which can be plotted by gnuplot to 
	show file seeking behavior.

./MANIFEST
	Added new files.

Changes since 19980713
----------------------

./config/conclude.in
	Fixed so `make test' and `make progs' work on a clean source tree.

Changes since 19980710
----------------------

./Makefile.in
./config/commence.in
./config/conclude.in
./config/depend.in
./src/Makefile.in
./test/Makefile.in
	Tests are no longer installed for `make install'.  Added a new 
	target `make tests' that builds the tests but doesn't run them.

./configure.in
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
	Added detection of fork() and waitpid().  If present the
	contants HAVE_FORK and HAVE_WAITPID will be defined in
	H5config.h.

./test/dtypes.c
	Minor tweaks for systems that don't have fork() or waitpid().

./MANIFEST
./tools			[NEW]
./tools/Makefile.in	[NEW]
./tools/h5debug.c	[NEW]
./tools/h5import.c	[NEW]
./tools/h5ls.c		[NEW]
./tools/h5repart.c	[NEW]
	Added a tools directory and moved tools from the src directory 
	to here.


Changes since 19980709
----------------------

./README
./bin/release
	The first line of the README file is updated automatically
	by the `release' script to associate a date with a release
	number. For example:

	    This is hdf5-1.0.9a released on 1998-06-09 18:00 UTC
            Please refer to the INSTALL file for installation instructions.

./src/H5public.h
	Release number incremented.  This happens automatically now if 
	you run the `release' script in `-batch' mode.  I'll stop
	documenting changes to this file unless they're something
	other than a release number change.

./MANIFEST
	Added Elena's new files.


Changes since 19980708
----------------------

./src/Makefile.in
	Fixed missing H5Zpublic.h header file.

./src/H5Fistore.c
	Indented some printf's in the left margin so various C source
	tools work correctly.

Changes since 19980708
----------------------

./src/H5Fistore.c
./src/H5S.c
	Fixed places where `herr_t' functions returned NULL for
	failure: H5F_istore_get_addr() and printf(?!?) (probably
	because a printf() was in the first column :-/ so I don't know 
	what function it really was that I fixed), and H5S_extent_copy().

./src/H5Fprivate.h
	Added declarations for H5F_istore_get_addr() and
	H5F_istore_allocate().

./src/H5S.c
./src/H5Sprivate.h
	Split H5Sset_extent_simple() into H5S_set_extent_simple() and
	replaced calls to the API function with calls to the internal
	function.

	Changed calls to H5Screate() to H5S_create() and H5Sclose() to 
	H5S_close().

./src/H5Shyper.c
./src/H5Spoint.c
	Removed unused labels and variable.

./src/H5T.c
./src/H5Tconv.c
	Changed calls to H5Tfind() to H5T_find().

./src/H5TB.c
	Split function return type onto a separate line for five
	functions and added API tracing calls.


Changes since 19980708
----------------------

./MANIFEST
	Alphabetized.  `d' comes before `e' :-)

./bin/release
	Added the `-batch' option which causes the script to not ask
	questions and to automatically update the minor version
	number and set the patch level back to `a'.  This is intended
	to be used for the daily snapshots:

	   #! /bin/sh
	   set -e
	   cd ~/hdf5
	   make distclean
	   make test
	   bin/release -batch tar compress gzip bzip2
	   mv ./releases/* /repository

./src/H5Z.c
	Removed warnings about unused variables when the zlib.h header 
	file is present but libz.a isn't.

./INSTALL
./configure.in
./doc/html/tracing.html
	Made API tracing the default (you still need to define the
	HDF5_TRACE environment variable to get results) and change the 
	name from `--disable-tracing' to `--disable-trace' to make it
	consistent with the other switches.

	Changed `site config file' to `host config file' to match the
	documentation.

./doc/html/H5.user.html
	Added a reference to the `tracing.html' file.

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/H5T.c
./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).

Changes since 19980707
----------------------

./bin/trace
./src/H5.c
./src/H5private.h
./src/H5A.c
./src/H5D.c
./src/H5F.c
./src/H5G.c
./src/H5P.c
./src/H5Pprivate.h
./src/H5S.c
./src/H5T.c
	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.

Changes since 19980706
----------------------

./src/H5public.h
	If sizeof(size_t)==sizeof(long long) then we define `hsize_t'
	in terms of size_t to get rid of warnings on systems that
	treat `long long' the same as `long'.

Changes since 19980702
----------------------

./src/H5T.c
	Prints statistics for no-op conversions also.

	For now, hardware floating point conversions may or may not
	raise SIGFPE depending on the hardware, operating system,
	etc.  Software conversions never raise SIGFPE and use +Inf or
	-Inf for overflow.

./test/dtypes.c
	Catches SIGFPE and causes the test to be skipped.  Better test 
	for NaN.

./config/irix5.3
	Removed the -U_POSIX_SOURCE because it was removed from the
	main makefiles.

./bin/trace
./src/H5S.c
	Fixed a typo that prevented tracing info from being added to
	new API functions.

Changes since 19980702
----------------------

./MANIFEST
	Added new files from testpar directory.

./config/commence.in
	Removed -D_POSIX_SOURCE because hdf5 uses a couple of
	non-Posix things when certain debugging flags are switched on.


Changes since 19980630
----------------------

./MANIFEST
./configure.in
./examples/Makefile.in	[NEW]
	Added a Makefile.in for the examples directory.  To generate
	the Makefile run configure again.


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/H5.c
./src/H5private.h
./src/H5A.c
./src/H5AC.c
./src/H5D.c

./src/H5T.c
./src/H5Tbit.c
./src/H5Tconv.c
	Fixed various compiler warnings on Irix64.

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

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


Changes since 19980618

./test/hyperslab.c
./test/istore.c
	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/H5MFprivate.h
	Changed H5MF_free() to H5MF_xfree() since calling it with an
	undefined address is allowed.

./test/cmpd_dset.c
./test/dsets.c
./test/dtypes.c
./test/external.c
./test/tattr.c
./test/th5s.c
	Organized the predefined data types.

./html/H5.intro.html
	NO MODIFICATIONS!  This file is a mess (obviously generated
	from something else) so I skipped updating it!

./src/h5ls.c
./test/dsets.c
./test/tattr.c
./test/th5s.c
	Added extra argument to H5Sget_dims() calls per Albert's last
	update.

Changes since 19980617
----------------------

./src/H5T.c
	Fixed a potential division by zero error.

./src/H5Fistore.c
	Fixed an assertion failure that I accidently introduced with
	the previous changes.

Changes since 19980616
----------------------

./html/tracing.html	NEW
	This entire update is to make it possible for the library to
	print the name, arguments, and return value of every API call
	without requiring any extra work from developers or app
	programmers.  This file describes how this all works.

./configure.in
	Added the `--enable-tracing' switch.  If you use it then the
	library will include code to print API function names,
	argument names and values, and function return values.
	However, you must then turn on the tracing by setting the
	HDF5_TRACE environment variable to a file descriptor number.
	The default is `--disable-tracing' since enabling it causes a
	slight increase in library size and a slowdown resulting from
	an extra function call for each API function call (I couldn't
	even measure the slowdown :-)

./bin/trace		NEW
	A perl script that synchronizes the H5TRACE() macro calls in
	the *.c files with the function return type and formal
	argument names and types.  If you use GNU make and gcc then
	this will be done automatically, otherwise just invoke this
	script with the names of one or more .c files.  You could do
	it by hand to, but encoding argument types is a little tricky
	at first.

./config/commence.in
	Added the $(TRACE) macro, which defaults to the no-op.
	Added -D_POSIX_SOURCE to the compiler command line.

./src/Makefile.in
	Override the default for $(TRACE).

./config/depend.in
	Automatically calls $(TRACE) to synchronize the H5TRACE()
	macros in any source file that changed.  As with makefile
	dependencies, one way to force synchronization of all files is 
	to remove the `.depend' file.

./MANIFEST
	Added new files.

./src/H5Eprivate.h
	Modified HRETURN_ERROR() and HRETURN() for tracing.

./src/H5.c
./src/H5private.h
	This is where the real tracing work really happens, in
	H5_trace().

./src/H5A.c
./src/H5D.c
./src/H5G.c
./src/H5P.c
./src/H5S.c
./src/H5Z.c
	Added H5TRACE() calls to all API functions.  You don't really
	need these changes if you don't want to merge your stuff
	because they can be generated automatically by going to the
	hdf5/src directory and saying ../bin/trace *.c

./src/H5T.c
	Added H5TRACE() calls.  Other stuff below.

./src/H5E.c
./src/H5Epublic.h
	Added H5TRACE() calls.  Created a type H5E_auto_t for the
	`func' argument of H5Eset_auto() and H5Eget_auto() to make
	those arguments easier to parse for tracing. It should also
	make it clearer for users that don't know how to read
	complicated ANSI data types.

./src/H5F.c
	Added H5TRACE() calls.  Changed a couple `uintn' argument
	types in API functions to `unsigned int' since `uintn' part of 
	the API.  Changed a few "can't" and "cant" error messages to
	"unable to".

./src/H5Ipublic.h
	Removed H5_DIRECTORY from the H5I_group_t enum.  It wasn't
	used anywhere.

./src/H5Tconv.c
	Removed an unused label.

./src/H5Fistore.c
./src/H5Oattr.c
./src/H5Odtype.c
./src/H5T.c
./test/dsets.c
./test/dtypes.c
	Fixed a warning about a variable possibly used before it's
	initialized.  Added __unused__ to turn off some unused
	argument warnings that pop up when debugging is turned off and 
	optimizations are turned on.



Changes since 19980612
----------------------

./src/H5Tbit.c
./MANIFEST
./test/Makefile.in
./test/bittests.c	NEW
	Finished the bit vector operations and added test cases.

./src/H5Tconv.c
./test/dtypes.c
	Finished integer->integer general conversion and added test
	cases. Overflows and underflows are handled by substituting
	the closest possible value.  Examples:

	   (unsigned)0xffff -> (unsigned)  0xff
	   (  signed)0xffff -> (unsigned)0x0000
	   (unsigned)0xffff -> (  signed)0x7fff
	   (  signed)0x7fff -> (  signed)  0x7f
	   (  signed)0xbfff -> (  signed)  0xbf
	   (  signed)0x8000 -> (  signed)  0x80

./src/H5private.h
	Added definitions for MIN and MAX that take 3 or 4 arguments:
	MIN3(), MIN4(), MAX3(), MAX4(). Also added MIN2() and MAX2()
	as aliases for MIN() and MAX().

./test/tattr.c
	Removed some redundant `&' operators.

./configure.in
./src/H5config.h.in	[regenerated]
./src/H5.c
	Fixed warnings on DEC where long double is the same as
	double.



Changes since 19980610
----------------------

THIS CHECKIN IS FOR QUINCEY -- NOT EVERYTHING WORKS (but it compiles)
MOST OF THE CHANGES ARE FOR BETTER TYPE CONVERSION IN THE NEXT ALPHA

./MANIFEST
./src/H5Tbit.c		NEW
./src/Makefile.in
	Bit vector operations (not done yet)

./configure.in
	Added -lm to the library list, needed by bit-vector operations
	and conversion functions.

	Removed vestiges of PARALLEL_SRC no longer used by the
	makefiles. Albert came up with a better way (that actually
	works :-)

./src/H5D.c
	No code changes.  Split a couple of long lines, refilled a
	couple multi-line comments.

./src/H5T.c
./src/H5Tpublic.h
	Fixed a bug reported by Jim Reus regarding conversion of
	compound data types whose members require conversions which
	are satisfied by as-yet unregistered soft conversion
	functions.

	Added H5T_IEEE architecture, but the funny-looking integer
	types will be changed to H5T_BE_ and H5T_LE_ architectures
	with the type names changed to match the H5T_NATIVE_ integers.

	Added an H5Tconvert() but it hasn't been documented or tested
	yet.

./src/H5Tconv.c
./src/H5Tpkg.h
	Registered conversion functions integer->integer (a general
	case) and integer->float (for a specific case).  The
	integer->integer conversion depends on the bitvector
	operations which aren't finished yet and the int->float
	conversion hasn't been retested since it was borrowed from
	AIO. Don't look at them yet, they're ugly :-)

./src/H5detect.c
	Fixed a typo which caused the msb_pad field of an atomic type
	to not be initialized.

./test/dtypes.c
	Added a test for number conversions but it's commented out
	until the conversion stuff is truly working.


Changes since 19980605
----------------------

./html/Files.html
./src/H5F.c
./src/HFcore.c
./src/H5Ffamily.c
./src/H5Flow.c
./src/H5Fmpio.c
./src/H5Fprivate.h
./src/H5Fsec2.c
./src/H5Fsplit.c
./src/H5Fstdio.c
./src/H5MF.c
./src/H5P.c
./src/H5Ppublic.h
	Added H5Pset_alignment() so that it is now possible to align
	file allocation requests on application-specified
	boundaries. Any request >= the specified threshold will begin
	on an address which is a multiple of the specified
	alignment. Defaults are one for threshold and alignment. The
	alignment is done on relative addresses, so the size of the
	user block can affect the location of the data in the file.

./src/H5D.c
./src/dsets.c
	Added a test for, and fixed the data space caching bug in
	datasets.  Extending a dataset through one handle will cause
	all other handles to the same dataset to get the new dataset
	size.

./src/H5S.c
./src/H5Sprivate.h
	Removed an unused argument from H5S_read() which duplicated
	information from the other argument.

./config/linux
	Made `--enable-parallel' the default on my system.  It used to
	be that way before but then I accidently turned it off and
	forgot about it.

./src/H5Fmpio.c
	Qualified some function arguments with __unused__.  Changed a
	couple places where NULL was returned on error for herr_t
	functions.

./src/H5P.c
	Removed unused autos from H5Pset_mpi().

Changes since 19980604
----------------------

./src/H5A.c
	Named data types can have attributes.

	Fixed bugs where the API functions didn't check the return
	values of their internal counterparts and thus the automatic
	error reporting didn't work.

	Fixed some places where the error stack wasn't cleared after a
	function returned failure.

	Data types returned by H5Aget_type() are always read-only.

	If the `attr_num' argument of H5Aiterate() is null then it
	acts like H5Giterate() instead of failing -- it begins
	processing attributes with the first one.

./src/H5D.c
	We check for allocation overruns when scalar datasets are
	stored in external files.

./src/H5O.c
	H5O_modify() will fail if the message is >=16kB.

./src/H5Oattr.c
	Split some long lines

./src/H5T.c
./src/H5Tprivate.h
	Added H5T_entof() to support attributes on named types.

./src/h5ls.c
	Prints the names of attributes and their sizes.

./test/cmpd_dset.c
./test/dsets.c
./test/dtypes.c
./test/extend.c
./test/external.c
./test/gheap.c
./test/istore.c
./test/links.c
./test/shtype.c
	If the environment variable HDF5_NOCLEANUP is defined then the 
	temporary files are not removed.  The testhdf5 program still
	has the bug that it removes *.h5, clobbering test files from
	other programs... oh well.

./test/dtypes.c
	Added attribute tests.

Changes since 19980604
----------------------

./html/Datatypes.html
	Updated documentation for named data types and type sharing.

./src/H5Farray.c
	Split a couple long lines.

./src/H5T.c
	The H5T_copy() demotes immutable types to read-only types so
	they're cleaned up properly and memory is not leaked.

./test/dtypes.c
	Modified to be more consistent with other tests.  Removed all
	internal header files, constants, types, and functions calls
	since the API is now complete enough to test
	everything. Temporary files are now removed.

Changes since 19980526
----------------------

./MANIFEST
	Added ./html/h5s.examples.

./html/H5.format.html
	Added new information about object header message sharing.
	Reformatted and indented some old stuff.

./src/H5A.c
./src/H5D.c
./src/H5Tconv.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/H5Gent.c
./src/H5Gpkg.h
./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.

./src/H5Oattr.c
./src/H5Ocomp.c
./src/H5Ocont.c
./src/H5Odtype.c
./src/H5Oefl.c
./src/H5Olayout.c
./src/H5Oname.c
./src/H5Osdspace.c
./src/H5Oshare.c
./src/H5Ostab.c
	Changed the data type for the shared message info struct to
	H5O_shared_t and added an extra initializer to the class
	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.

./test/dtypes.c
	Added tests for transient and named types and their use in
	datasets.

./test/shtype.c
	Commented out all the tests since they no longer apply.

./test/chunk.c
	Removed a couple int->double coercion warnings.

Still to come:
	Documentation


Changes since 19980522
----------------------

./MANIFEST
./html/Caching.html	[NEW]
./html/H5.user.html
	Added some info about caching.

Changes since 19980513
----------------------

./html/Datasets.html
	Fixed a couple of typos.

./src/H5.c
	Added the `Z' modifier to HDfprintf() for `size_t' sizes.  Use
	it like this:
	   HDfprintf(stderr,"size is %Zd\n", (size_t)x);

./src/H5AC.c
./src/H5F.c
./src/H5Fprivate.h
	The maximum number of meta data objects that can be cached can 
	be set from the application (but the library might not honor
	it every time; it's a hint).

./src/H5D.c
	Changed a warning message so it's not so alarming.

./src/H5Fistore.c
	Chunks can be cached.

./src/H5O.c
./src/H5Oprivate.h
	Added H5O_copy() and H5O_free() to copy and free messages.

./src/H5P.c
./src/H5Ppublic.h
	Added H5Pset_cache() and H5Pget_cache() and changed lots of
	"template" to "property list".

./src/H5Z.c
./src/H5Zpublic.h
	Miscellaneous little things to clean up.  Mostly just removed
	H5Z_MAXVAL and added H5Z_USERDEF_MIN and H5Z_USERDEF_MAX.

./MANIFEST
./test/Makefile.in
./test/chunk.c		[NEW]
	Added a performance test for chunk caching.  It looks at the
	amount of I/O instead of timing because timing is partly
	dependent on the chunk size and I wanted a measurement that
	was a function of only the cache size.  Run `chunk' with no
	arguments and then say `gnuplot x-gnuplot' to see the plots
	(press return between plots). Postscript files are created for
	each plot.

./test/big.c
./test/cmpd_dset.c
./test/extend.c
./test/external.c
./test/gheap.c
	Added H5F_ACC_DEBUG so we can see cache performance
	statistics.


Changes since 19980501
----------------------

./src/H5Bprivate.h
./src/H5F.c
./src/H5Ffamily.c
./src/H5Fprivate.h
./src/H5Gpkg.h
./src/H5MF.c
./src/H5P.c
./src/H5Ppublic.h
./test/big.c
./html/Big.html
./html/Files.html
	Family members can now be any size >1kB.  Got rid of some
	places where we were reading a property list after it was
	closed.

./MANIFEST
./src/Makefile.in
./src/h5repart.c
	A program to repartition file families.  The source and/or
	destination may be files or file families.  Examples:

	   testhdf5 -c -o stab
	   h5repart -m 1m   tstab2.h5 x%05d.h5
	   h5repart -m 100k x%05d.h5  y%05d.h5
	   h5repart         y%05d.h5  z.h5
	   diff tstab2.h5 z.h5

./src/h5ls.c
	Added a usage message, replaced assertions with error
	messages.

./config/linux
	Made a warning message more obvious.  Added better
	optimization flags for Pentium-Pro's.
	


Changes since 19980430
----------------------

./src/H5G.c
	Fixed a read/write of free memory that my home-brew purify
	doesn't catch (yet :-)

Changes since 19980428
----------------------

./src/H5A.c
./src/H5F.c
./src/H5G.c
./src/H5O.c
./src/H5Osdspace.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Z.c
./test/big.c
./test/cmpd_dset.c
./test/dsets.c
./test/extend.c
./test/istore.c
	Now that I have a home-grown version of Purify I fixed all the
	leaks in all the test files.

Changes since 19980424
----------------------

./src/H5A.c
./src/H5T.c
	Fixed memory leaks.  More to come later but PureAtria doesn't
	make a Linux version of purify and the free version doesn't
	compile with the new SMP Linux kernels so I had to debug over
	the internet on a day that Sprint seemed to be having routing
	problems... oh well.  I got rid of most of the leaks.

./src/H5Apublic.h
	Includes H5Ipublic.h for types in the header file.

./src/H5O.c
	Comments improved for H5O_read()

./test/tattr.c
	Removed a non-ANSI empty initializer.

./test/dsets.c
	Include <string.h>

./test/istore.c
	Fixed a non-ANSI pointer conversion.


Changes since 19980424
----------------------

./src/H5F.c
./src/H5Ffamily.c
./src/H5Fsplit.c
./src/H5P.c
	The H5Pget_family() and H5Pget_split() always return a file
	access property list even if it's the default.

	It is an error to set the default low-level driver to a
	composite driver at compile time.

./src/H5T.c
	Fixed a memory leak associated with compound data types.

Changes since 19980422
----------------------

./acconfig.h
./configure.in
./config/BlankForm
./src/H5.c
	Configure tries to figure out how to print `long long' types
	and then defines PRINTF_LL_WIDTH to be `ll' or `q' or
	something.  It does this by running little sprintf() programs
	with various formats until it gets one that works.  If this
	causes problems when cross compiling (like with parallel
	machines) then you may add the following to the appropriate
	config file:

	       hdf5_cv_printf_ll=${hdf5_cv_printf_ll='ll'}	or
	       hdf5_cv_printf_ll=${hdf5_cv_printf_ll='q'}	or
	       hdf5_cv_printf_ll=${hdf5_cv_printf_ll='l'}
								

./config/intel-osf1
./config/irix5.3
	Updated these config files to match the others.  This allows
	the `--enable-production' configure flag to work properly.

./MANIFEST
	Added INSTALL_parallel.ascired, examples/Attributes.txt,
	html/Attributes.html, testpar/Makefile.ascired.  Removed
	H5Dpkg.h


./src/H5A.c
./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpkg.h		[REMOVED]
./src/H5Tpkg.h
./src/H5Tprivate.h
	Rearranged some header stuff so H5A doesn't have to include
	the package-private header files that don't belong to it.

./src/H5E.c
	Added the H5E_ATTR message to the major error struct.

Changes since 19980421
----------------------

./bin/release
./src/H5.c
./src/H5private.h
./src/H5public.h
./src/H5Fpublic.h
	Changed the version number constants to names that begin with
	H5_VERS_ and added macros that check that the version numbers
	in the include files match the version number of the library.

./MANIFEST
./html/H5.user.html
./html/Version.html    [NEW]
./html/version.obj     [NEW]
./html/version.gif     [NEW]
	Documented version numbers and the macros, constants, and
	functions associated with them.

./bin/versinc
	A perl script that increments the minor version number and
	sets the patch level back to zero.  This is intended to be
	invoked from the top of the source tree by a cvs commit
	anywhere in the source tree. Quincey?

./src/H5O.c
./src/H5Oprivate.h
	Added H5O_count() to count the number of object header
	messages of a particular type.  Quincey needs this for the
	attribute package.

./test/dsets.c
	Fixed warnings. Enabled the small strip-mine buffer test.

./config/linux
	Added optimizations for the Pentium-Pro for production mode.

Changes since 19980417
----------------------

This checkin completes the compression stuff almost two weeks ahead of
schedule.  It should now all be working and documented.

./Makefile.in
./config/commence.in
	A distclean causes the distribution makefile to be copied to
	Makefile again.

./src/H5D.c
	Opening a compressed dataset now works properly.

./src/H5P.c
./src/H5Ppublic.h
	The H5Pset_compression() and H5Pget_compression() now work as
	documented.

./src/H5T.c
	Fixed a bug that causes the library to crash sometimes if
	debugging is turned on for the `t' package.

./src/H5Z.c
	Fixed a bug where the number of bytes attributed to
	compression overruns was too low in the debugging output.

./test/dsets.c
	More compression tests: reading of uninitialized data, opening
	an existing dataset and reading it, partial I/O which isn't
	aligned on chunk boundaries, and use of application-defined
	compression methods.

./MANIFEST
	Removed ./test/dspace.c.


Changes since 19980414
----------------------

./html/Compression.html		 [NEW]
./html/Datasets.html
./html/H5.format.html
./html/H5.user.html

	Compression is now mostly working.  Don't try to open a
	compressed dataset though because the compression message
	won't be read.

./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
	Added timing support.  When compiled with H5T_DEBUG defined
	the library will print conversion bandwidths when the library
	closes.  The H5Tregister functions take a string as the first
	argument so the statistics output is meaningful.

./MANIFEST
	Added new files.

./configure.in
./src/H5config.h.in
	Check for getrusage().  Check for compress2() in libz.a and
	the zlib.h header file.  Added `z' to the debug list.

./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
./src/debug.c
	Cleaned up some indentation and added support to print istore
	B-trees.  From the debugger, give the B-tree address and the
	dimensionality from the layout message of the object header.

./src/h5ls.c
	The oid is printed as  w:x:y:z where w and x are the file ID
	and y and z are the OID within the file.  You can give z or
	y*2^32+z as an argument to the debugger to print the object
	header for the object.

./src/H5AC.c
	Cleaned up statistics and made them match those reported by
	H5T and H5Z.

./src/H5MM.c
./src/H5MMprivate.h
./src/H5Fistore.c
	Finally got rid of a couple of long-standing const cast
	warnings.

./test/Makefile.in
	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
	header.  It's format is described in H5.format.hml.

./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'.

Changes since 19980409
----------------------

./INSTALL
./INSTALL_MAINT
	Updated installation instructions.

./html/Big.html		     [NEW]
	A guide to using big datasets on small machines.

./MANIFEST
	Added Big.html and INSTALL.ascired.

./html/Datasets.html
./html/Dataspaces.html
./html/Datatypes.html
./html/Files.html
./html/H5.api.html
./html/H5.intro.html
./html/H5.sample_code.html
./html/H5.user.html
	Updated documentation by changing lots of `size_t' arguments
	to `hsize_t'.  Added line numbers to some examples.

./html/H5.intro.html
	Perhaps someone want's to volunteer to make this file
	human-readable?


Changes since 19980408
----------------------

./src/H5Osdspace.c
./html/H5.format.html
	In the past we were allowed to have >2GB files on a 32-bit
	machine as long as no dataset within the file was larger than
	4GB (or whatever sizeof(size_t) is).  That's been fixed now.
	All dataset size calculations are done with `hsize_t' which is
	normally defined as `unsigned long long'.

./src/H5F.c
./src/H5Ffamily.c
./src/H5Fprivate.h
./src/H5P.c
./src/H5Ppublic.h
	The file family member size can now be set/queried.  The
	default is still 64MB, but it can be set to 1GB by saying:

	    H5Pset_family (plist, 30, H5P_DEFAULT);

	When opening an existing file family the specified
	bits-per-member is ignored and the first member of the family
	determines the bits-per-member, which can be retrieved with
	H5Pget_family().

./acconfig.h
./configure.in
./src/H5config.h
./src/H5public.h
	Added `--disable-hsizet' so that those with old GCC compilers
	(<2.8.1) can still compile the code.


./src/H5.c
./src/H5private.h
	Added HDfprintf() which works just like fprintf() except you
	can give `H' as a size modifier for the integer conversions
	and supply an `hsize_t' or `hssize_t' argument without casting
	it.  For instance:

	    hsize_t npoints = H5Sget_npoints(space);
	    HDfprintf(stdout,"Dataset has %Hd (%#018Hx) points\n",
		      npoints, npoints);

	You can now give `%a' as a format to print an address, but all
	formating flags are ignored and it causes the return value of
	HDfprintf() to not include the characters in the address (but
	who uses the return value anyway :-). Example:

	    H5G_t *grp;
	    HDfprintf(stdout, "Group object header at %a\n",
	              &(grp->ent.header));

	Added HDstrtoll() which works exactly like [HD]strtol() except
	the result is an int64.

./src/debug.c
	Large addresses can now be entered from the command-line.  Use
	either decimal, octal (leading `0') or hexadecimal (leading
	`0x') when giving the address.

./src/h5ls.c
	The printf format for dataset dimensions was changed to `%Hu'
	to support large datasets.

./test/big.c		[NEW]
	A test for big datasets on 32-bit machines.  This test is not
	run by default.  Don't try to run it on an nfs-mounted file
	system or other file system that doesn't support holes because
	it creates two 32GB datasets of all zero.

	Anything having to do with the size of a dataset now uses the
	types `hsize_t' and `hssize_t' which must be the same size and
	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
	the formal name.  This also has the effect of supressing
	warning messages for gcc since it's defined to be
	`__attribute__((unused))' in the H5private.h file.

./src/debug.c
./src/h5ls.c
	If the file name contains a `%' then the file is opened as a
	file family with H5P_DEFAULT for the file member access
	property list.

./src/h5ls.c
	The group name is optional, defaulting to `/'.	

./src/hdf5.h
	Added some missing public header files.

Changes since 19980403
----------------------

./configure.in
	Moved setting of compiler warning switches earlier in the file.
	Turned on more warning switches to gcc.

./config/linux
	Prints a warning if the gcc version is less than 2.8.1 since
	that version has problems with register allocation for `long
	long'.

./html/Datatypes.html
	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.

	Fixed comparisons between signed and unsigned values. Fixed
	warnings about unused function arguments.


Changes since 19980402
----------------------

./MANIFEST
./test/Makefile.in
./test/shtype.c		[NEW]
	Added some tests for shared data types.

./configure.in
	Removed MF and HL from the default debug list since.  MF
	because it hasn't been implemented yet and HL because it
	produces lots of annoying messages about adjusting the size of
	local heaps.

./src/H5F.c
./src/H5T.c
./src/H5Tprivate.h
	Fixed a bug with opening the same file twice.  The first close
	on the file_id incorrectly closed shared data structs.
	Closing a file now correctly unshares data types that might be
	pointing into that file.

./src/H5T.c
./src/H5Tpublic.h
	Added an H5Tis_shared().  The caller supplies a file and a
	data type and the function returns true if the data type is
	currently marked for sharing in that file.

./src/H5AC.c
./src/H5F.c
./src/H5HL.c
./src/H5HG.c
./src/H5MF.c
./src/H5O.c
	We now detect errors sooner when writing to a read-only
	file. In the past, the error might not show up until the
	cached item was flushed, and it was sometimes possible to not
	even get an error!

./src/H5I.c
./src/H5Iprivate.h
	If the search function fails then H5I_search() returns
	failure.  Also, the first argument for the search function
	isn't const anymore because we might want the search to have
	side effects (like calling H5T_unshare() for all shared data
	types whose file just closed).

	

Changes since 19980330
----------------------

./MANIFEST
./src/Makefile.in
./test/Makefile.in
	Added new files.

./config/linux
./src/H5HL.c
./src/H5HLprivate.h
./src/H5MF.c
./src/H5MFprivate.h
	Added `-DH5HL_DEBUG -DH5MF_DEBUG' to the debug list.

./html/H5.format.html
	Updated shared object message information.

./src/H5D.c
	Datasets can now share data types.

./src/H5F.c
	Updated a comment that referred to H5ACC_WRITE.

./src/H5HG.c
./src/H5HGprivate.h
	Moved a few things around.  Made debugging better so you can
	now give a collection address to ./src/debug and it shows some
	useful stuff.

./src/H5O.c
./src/H5Ocont.c
./src/H5Odtype.c
./src/H5Oefl.c
./src/H5Olayout.c
./src/H5Oname.c
./src/H5Onull.c
./src/H5Oprivate.h

./src/H5Ostab.c
	Supports shared messages.

./src/H5T.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
	The H5Tshare() function allows the user to give the library
	hints about how a data type will be used.

./test/shtype.c
	Tests the H5Tshare() function.

./test/gheap.c
	Tests the global heap.

./configure.in
./config/BlankForm	[NEW]
./config/alpha-dec
./config/freebsd2.2.1
./config/hpux10.20
./config/irix6.2
./config/irix64
./config/linux
./config/powerpc-ibm-aix4.2.1.0
./config/rs6000-ibm-aix4.1.4.0
./config/solaris2.5
	Cleaned up lots of configuration stuff and made the site
	configuration files lots easier and more uniform.  To make a
	new file grab the BlankForm and modify it.

	By default, debugging is turned on for most packages.  Within
	a package one can use `#ifdef H5AC_DEBUG' to wrap debugging
	code.  Other options are:

	   --enable-debug
	   --enable-debug=yes
	       The default, most but not all packages.

	   --disable-debug
           --enable-debug=no
	   --enable-debug=none
	       The symbol NDEBUG is defined and none of the package
	       debug symbols.

	   --enable-debug=all
	       Debugging is turned on for all packages.  This might
	       produce lots of output.

	   --enable-debug=g,d
	       Debugging is turned on for H5G and H5D.

	A compile mode is also now supported

	   --enable-production
	   --enable-production=yes
	       The library is compiled with optimizations turned on.
	       The compiler flags are augmented by adding PROD_CFLAGS
	       and PROD_CPPFLAGS which are defined in the site config
	       file.

	   --disable-production
	   --enable-production=no
	       The default.  The library is compiled for development
	       by including DEBUG_CFLAGS and DEBUG_CPPFLAGS defined in
	       the site config file.  This is usually just `-g'.

	   --enable-production=profile
	   --enable-production=pg
	       Builds a library for profiling by including the flags
	       from PROFILE_CFLAGS and PROFILE_CPPFLAGS defined in the
	       site config file.  This is usullay just `-pg' but it
	       could include optimization flags as well depending on
	       the type of profile one wants.

	In summary, configure by saying `./configure' and you'll get a
	development version of the library.  Configure by saying
	`./configure --enable-production --disable-debug' and you'll
	get a production version with no debugging code.

./MANIFEST
./src/H5HG.c		[new]
./src/H5HGprivate.h	[new]
./src/H5HGpublic.h	[new]

	Added global heaps, H5HG.  This compiles but is untested.

./src/H5D.c
./src/H5G.c
./src/H5Gnode.c
./src/H5Gstab.c
./src/H5HL.c		[renamed from H5H.c]

./src/H5Oefl.c

./src/hdf5.h
./test/theap.c
	Renamed local heaps from H5H to H5HL.

./src/H5AC.c
./src/H5ACprivate.h
./src/debug.c
	Added debugging support for global heap collections.

./html/H5.format.html
	Ripped out the old small object heap documentation and added
	documentation for the new global heap.

./html/H5.api.html
./src/H5P.c
./src/H5Ppublic.h
./src/H5F.c
./src/H5Fprivate.h
./src/H5private.h
	The H5Pget_version() function no longer returns a small object
	heap version number.  Instead, each collection of the global
	heap has its own version number instead of a single number in
	the file boot block.

./bin/release
	Omit files marked for removal by CVS even though the removal
	hasn't been committed yet.

./test/iopipe.c
	Removed warnings about casting unsigned int to double on Irix64.

./MANIFEST
	Removed ./test/testpar/phdf5sup.c

Changes since 19980324
----------------------

./src/H5D.c
	Zero element requests for H5Dread() and H5Dwrite() succeed.

./src/H5F.c
./src/H5Fprivate.h
	All files will have a root group. This greatly simplifies the
	library at the expense of ~1k extra bytes in files that have
	only one object.

./src/H5D.c
./src/H5Dprivate.h
./html/Groups.html
	Functions that used to take a file ID and an object name can
	now take a group ID instead of a file ID.  This doesn't change
	the API, only it's documentation.

./src/H5G.c
./src/H5Gprivate.h
./src/H5O.c
./src/H5Oprivate.h
	Removed extra file arguments from some internal functions
	since the file pointer can be found from the group pointer or
	a symbol table entry (ent->file or H5G_fileof(group)).
	Besides, when we eventually implement mounting one file on
	another, H5G_namei() might return a different file than what
	you gave it, and that file is part of the returned symbol
	table entry.

./src/H5G.c
	Fixed bug with `.' appearing in a name. It used to hang the
	library.

./src/Makefile.in
./src/h5ls.c		[NEW]
./MANIFEST
	Added `h5ls' a simple program that takes a file name and a
	directory and lists the contents of that directory using
	H5Giterate().

./test/istore.c
	Changed an argument to H5G_create().

./test/tstab.c
	Removed test_1 which was testing that files with a single
	object don't have a root group.  This no longer applies.


Changes since 19980318

./src/H5B.c
./src/H5Bprivate.h
./src/H5G.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gpublic.h
./src/H5Gstab.c
	Implemented H5Giterate().  However, since most functions can't
	take a group ID in place of a file ID yet, there's not a whole
	lot that the operator can do besides print the name or something.

./test/H5O.c
	Fixed writing of four uninitialized bytes to the file as part
	of an object header.

./test/istore.c
	For some reason, `mpirun -np 1 istore' results in extra
	arguments on the command line that istore doesn't understand.
	I'm probably forgetting to call some MPI function in
	main(). Albert, Kim?  So I commented out the `exit(1)' for the
	time being.

Changes since 19980318
----------------------

./config/linux
	Turned on MPIO if the host name is `arborea' so I always
	compile it and realize when I break something instead of
	waiting for Albert or Kim to find it.

./configure
./Makefile.in
./bin/distdep		[NEW]
./config/conclude.in
./config/depend.in
./src/.distdep		[NEW]
./test/.distdep		[NEW]
	Added some code so non-GNU systems have a list of dependencies
	between the .c files and the .h files.  Hopefully this works
	and y'all don't have to keep saying `make clean' each time you
	change a header.

	On systems with GNU make, GCC, and Perl, the dependency
	information is generated automatically from rules in
	config/depend.in as has always been done.  But now extra files
	called `.distdep' (for `distributable dependencies) are left
	in each directory and these are part of CVS and thus
	releases.  (A `make dep' will create dependencies on demand
	without doing anything else.)

	On systems lacking one or more of the tools above, the various
	`.distdep' files are inserted into the end of the Makefiles.
	If you do developement on one of these systems you'll have to
	update the `.distdep' and/or Makefile by hand, or wait until
	you have access to a GNU system and do a `make dep'.


Changes since 19980316
----------------------

./src/H5D.c
./src/H5T.c
./src/H5Tprivate.h
	Fixed a bug found by Kevin Powell regarding preservation of
	existing data during a read or write when the source and
	destination data types are the same.  Thanks Kevin!

	Fixed a couple warnings on Irix64.

./src/H5D.c

./src/H5P.c
./src/H5Ppublic.c
./src/H5Tconv.c
./src/H5Tpublic.h
./test/cmpd_dset.c
	The application can now turn on/off the part of the I/O
	pipeline that deals with preservation of initialized data.
	The default is off since this will be the usual case and
	turning it on slows down the pipe.  Use H5Pset_preserve() and
	H5Pget_preserve().

./src/H5Fistore.c
	Added an optimization for reading/writing a single chunk of
	chunked storage.

./src/H5Odtype.c
./src/H5Oefl.c
./src/H5Olayout.c
./src/H5Oname.c

./src/H5Ostab.c
	Fixed warnings reported by marek@iiasa.ac.at.  Thanks Marek.

./src/H5Odtype.c

./src/H5Ssimp.c
./html/Datasets.html
	Finally implemented strip mining in the I/O pipeline, placing
	a user-defined upper bound on the amount of temporary memory
	used by the pipeline.  The default is 1MB type conversion and
	background buffers allocated/freed on demand.  However, the
	size can be changed and/or application-allocated buffers
	supplied with H5Pset_buffers() called on the data transfer
	property list passed to H5Dread() and H5Dwrite().

	Minor optimizations to H5Dread() and H5Dwrite().  More coming
	later...

./test/dsets.c
	Added calls to H5Pset_buffer() to test application-defined
	temporary buffers in the I/O pipeline.

./test/Makefile.in
	Removed `iopipe' from the list of confidence tests.  Saying
	`make timings' in the test directory runs timing tests.  I did
	this because (1) they don't really test anything new, and (2)
	they can take a long time to run.

./configure.in
./configure
./config/commence.in
	Added checking for `ar' then `xar' and set the $(AR) variable
	in the Makefiles.  The check is not performed if $AR is
	already defined in the environment (including being set in a
	config file).  We check for `-lcoug' for ASCI/Red.

Changes since 19980305
----------------------

./src/H5D.c
./test/external.c
	A contiguous dataset can now be stored in external files in
	such a way that the slowest varying dimension can be increased
	after the dataset is created and even written.  The user must
	have reserved enough space in the external file and the data
	space must allow an increase the the slowest varying dimension.
	See test_3() of ./test/external.c

./src/H5Oefl.c
	Fixed an overflow bug with unlimited external storage.

./src/H5V.c
	Fixed a cast warning.
	
./test/dsets.c
	Make better use of automatic error reporting.

Changes since 19980304
----------------------

./MANIFEST
	New files

./html/extern1.gif		[NEW]
./html/extern1.obj		[NEW]
./html/extern2.gif		[NEW]
./html/extern2.obj		[NEW]
./html/Datasets.html
	Documented external raw data storage.

./html/Datasets.html
./html/chunk1.gif		[NEW]
./html/chunk1.obj		[NEW]
	Added a picture and better description for chunking since it
	seems that people are thinking chunks are fixed-size at the
	file level instead of at the array level.

./src/H5D.c
./src/H5Dpublic.h
./test/external.c

	can be scattered throughout multiple files in any order.

./test/Makefile.in

Changes since 19980228
----------------------

./html/Dataspaces.html
./html/Errors.html
./html/Files.html
./html/H5.api.html
./html/review1.html
./src/H5private.h
./src/H5public.h
./test/dsets.c
./test/dtypes.c
	Removed all the types like `int32' and `intn' into private
	headers since they violate the naming scheme and pollute
	application name space.  Besides, our test files only use them
	in a handful of places and it's probably useless to export
	them to the app.  The app is always written in terms of
	standard numeric types or its own numeric types and probably
	never in terms of HDF5 numeric types.  If it were, then the
	user would have to copy from their type to hdf5 type for
	almost every hdf5 API function call!  Same goes for return
	values.  I also removed SUCCEED/FAIL from the API since apps
	should be checking against zero anyway.

	       if (FAIL==(space=H5Screate_simple(...))) /*wrong*/
	       if ((space=H5Fcreate_simple(...)<0))     /*right*/


./src/H5.c
	Changed arguments of H5version() from `uintn' to `unsigned'.

./src/H5Tpublic.h
./src/H5T.c
	Changed return type of H5Tget_nmembers() from `intn' to `int'
	

./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
	Changed `H5Asearch_func_t' to `H5A_search_func_t' and moved
	its definition from the public to the private header file.


./html/H5.format.html
	Documented changes made to the external file list (H5O_EFL)
	message.

./src/H5D.c
./src/H5Dprivate.h
./src/H5E.c
./src/H5Epublic.h
./src/H5O.c
./src/H5Oefl.c
./src/H5Oprivate.h
./src/H5P.c
./src/H5Ppublic.h
	Added partial support for external raw data files.  HDF5 can
	now describe external raw data files by listing the file
	names, offsets, and size for a dataset. However, we will
	restrict a dataset to be stored "contiguously" when the
	external file list is viewed as a single address space. The
	current implementation is unable to read/write to external
	files--that will come later this week as will documentation.
	For now, take a look at ./test/external.c, particularly the
	calls to H5Pset_external().

./test/Makefile.in
./test/external.c		[NEW]
./MANIFEST
	Added tests for external storage.  Note: the read test is
	supposed to fail at this point since reading external datasets
	is not implemented yet.  There is no write test.

./src/H5S.c
./src/H5Sprivate.h
./src/H5Ssimp.c
	Added H5S_get_npoints_max() to return the maximum possible
	number of data points in a data space.

	Added an extra argument to H5S_get_dims() which returns the
	maximum dims.

./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
./src/H5M.c			[DEPRICATED]
./src/H5Mpublic.h		[DEPRICATED]
	Changed `template' to `property list' in lots of places.
	
./src/H5Osdspace.c
	Removed an extra `\n' from a print statement.

./src/H5S_public.h
	Changed H5S_UNLIMITED to the maximum size_t value.

./test/extend.c
	"Extendable" is spelled "extendible".

./src/H5Farray.c
./src/H5V.c
./src/H5Vprivate.h
./test/hyperslab.c
	Strides are now type ssize_t instead of int.  These have
	nothing to do with the sample granularity arguments for
	hyperslabs, which are also called "strides" in the code.

./test/tstab.c
	Changed assumptions about default address and length sizes.

Changes since 19980227
----------------------

./html/Errors.html		[NEW]
./html/H5.user.html
./MANIFEST
	Documents the new error handling interface and gives examples.

./src/H5.c
./src/H5private.h
./src/H5Apublic.h
./src/H5E.c
./src/H5Eprivate.h
./src/H5Epublic.h
	Rewrote error handling. Got rid of `push' overloading and
	added a few API functions.  The error stack is statically
	allocated and not entered into H5A, simplifying error handling
	within the error handler. Rudimentary support for threads.
	Changed the names of some errors.

./src/H5G.c
./src/H5Gnode.c
./src/H5H.c
./src/H5O.c
./src/H5T.c
	Changed H5ECLEAR to H5E_clear().

./src/Makefile.in
	Alphabetized source list.

./test/dsets.c
	Turned off error reporting around functions that are expected
	to fail.  Error messages are sent to stdout.

./test/testhdf5.c
./test/testhdf5.h
	Turned off automatic error reporting since this file mostly
	calls internal functions and does its own error reporting.

Changes since 19980226
----------------------

./bin/release
	Changed default to not tag CVS sources.

./src/H5F.c
	Replaced a constant switch with preprocessor directives.
	Removed a local variable which was set but not used.

./src/H5Fprivate.h
	Changed `long long' to `int64' to get rid of ansi warnings in
	a few places.

	Fixed bugs in INT64DECODE() and UINT64DECODE() for big-endian
	architectures.  This fixes all the bugs with the Irix -64
	compile.

./src/H5F.c
	The default address and length sizes are set according to the
	sizeof(size_t) now that the bugs have been fixed.

./src/H5Fpublic.h
	Removed a trailing comma in an enumerated type.

./src/H5Fstdio.c
./src/H5Fsec2.c
	Added two more calls to fseek64() and lseek64(). Removed `long
	long' in place of `int64' to suppress -ansi warnings.
	
./src/H5P.c
	Replaced a FAIL with H5F_LOW_ERROR.

./src/H5private.h
./configure.in
	Increased version number to hdf5-1.0.1a since we've already
	released hdf5-1.0.0a.  Include <sys/types.h>.  Fixed
	indentation.  Fixed detection of off64_t for old Irix systems
	where it might be a struct.

./src/Makefile.in
	Moved a comment from the shell to the makefile since some
	versions of sh barf on interactive comments.

./config/linux
	Allow overriding of the CC variable from the command-line.  It
	still defaults to gcc but this allows us to specify a complete
	path from test scripts by saying:

	     CC=/usr/local/tools/gnu/gcc sh configure


Changes since 19980224
----------------------

./MANIFEST
	Changed names for P->S and C->P changes.

./INSTALL
	Added a note.

./html/Files.html
	Added a few details for some of the new H5Pset/get functions.

./src/H5F.c
./src/H5Fpublic.h
	Fixed automatic closing of files on exit().

	Added public H5F_ACC_DEBUG.  Using it to create or open a file
	turns on debugging for that file, which currently just prints
	cache statistics when the file is closed.

./src/H5G.c
	An error is returned if one tries to set the current working
	group to something other than a group.

./src/H5Gnode.c
	Fixed a symbol table bug.  Under certain circumstances it was
	possible to enter a symbol in such a way that lookup of that
	symbol failed. A bug report was sent to hdf5dev.

./src/H5P.c
./src/H5Ppublic.h
	Added the H5Pget_...() functions for file drivers.  The
	H5Pget_mpi() is a no-op that always fails.

Changes since 19980219
----------------------

./html/Files.html
./src/H5C.c
./src/H5Cpublic.h
./src/H5Ffamily.c
./src/H5Fprivate.h
./src/H5Fsplit.c
./test/tstab.c
	Added file-access property functions.

	The split driver takes file extensions as properties.

./src/H5A.c
./src/H5Aprivate.h
	Added some comments. Changed H5A_destroy() to call the free
	function on all the atoms that are destroyed. This fixes a bug
	where the file boot block isn't updated if the file isn't
	closed before calling exit().

	Removed extra `*' and `&' from some places.

./src/H5AC.c
	Replaced an occurrence of NO_ADDR with NULL.

./src/H5Odtype.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
	Data types of compound members are pointers.

./H5private.h
	Some changes to make lseek64() work on Irix 5.3 where header
	files don't realize that `long long' works.

./acconfig.h
./configure.in
	Removed definition for PHDF5 since it looks like everyone is
	useing HAVE_PARALLEL now.

./configure.in
./src/H5detec.c
	Added checks for gethostname() and getpwuid().

Changes since 19980219
----------------------

./src/H5A.c
./src/H5C.c
	Objects are removed from the group when there reference count
	hits zero regardless of whether H5A knows how to free the
	object.

./src/debug.c
./test/tstab.c
	Changed a zero to H5C_DEFAULT.

Changes since 19980206
----------------------

./configure.in
./src/H5Fprivate.h
./src/H5Fsec2.c
	We now detect and use lseek64() on systems that have it (e.g.,
	Irix64) and are able to generate >2GB files on Irix XFS file
	systems (and anything else that supports large files).  This
	change also removed some warning messages from the Irix `-64'
	compiler.

./configure.in
./src/H5Fprivate.h
./src/H5Fstdio.h
	We now detect and use fseek64() on systems that have it (e.g.,
	Irix64) and are able to generate >2GB files on Irix XFS file
	systems (and anything else that supports large files).  This
	change also removed some warning messages from the Iris `-64'
	compiler.

./src/H5E.c

./test/tstab.c
./testpar/phdf5.c
	Renamed file access constants to follow the naming scheme.
	Also changed the base names a little to be more accurate as to
	what they do.  The old names H5ACC_WRITE and H5ACC_OVERWRITE
	will temporarily work.

	     H5ACC_DEFAULT     --> H5F_ACC_RDONLY for H5Fopen()
	     H5ACC_DEFAULT     --> H5F_ACC_EXCL   for H5Fcreate()
	     H5ACC_WRITE       --> H5F_ACC_RDWR
	     H5ACC_OVERWRITE   --> H5F_ACC_TRUNC

	Albert or Kim: The H5ACC_INDEPENDENT and H5ACC_COLLECTIVE
	macros in H5Fpublic.h should be an enum typedef and have names
	more like H5F_MPIO_INDEPENDENT and H5F_MPIO_COLLECTIVE.  Also
	change the access_mode argument of H5Cset_mpio().

	H5Fcreate() and H5Fopen() are more strict now about which
	flags are acceptable for the operation.

./src/H5Fprivate.h
./src/H5F.c
./src/H5C.c
	Changed the file access template to make it more general.  A
	union contains a struct for each type of low-level driver and
	the default template is initialized at run-time.

./src/H5Fpublic.h
./src/H5F.c
	Added H5Fget_access_template() and cleaned up
	H5Fget_create_template().

./src/H5C.c
	The H5Cset_mpi() no longer trashes the file access template
	when an error is detected.  We check for errors and *then*
	update the file access template.

	Added H5C_close() so Albert and Kim have a place to release
	the MPI communicator and info from the file access property
	list.

	Kim or Albert: I notice in H5Cset_mpi() you copy the MPI
	communicator.  Do you need to do something similar in
	H5C_copy()?

./src/H5F.c
	Added more error checking for the file creation and access
	property lists because it used to be possible to make the
	library dump core by swapping the creation and access property
	list ID numbers of H5Fcreate().

./test/istore.c
./test/tfile.c
./test/th5p.c
./test/theap.c
./test/tohdr.c
./test/tstab.c
./testpar/testphdf5.c
	One must pass H5C_DEFAULT as the file creation or access
	property list in order to get the default property list.  It
	is no longer possible to pass zero or any other arbitrary bad
	object ID.

./src/H5Fcore.c
./src/H5Ffamly.c
./src/H5Flow.c
./src/H5Fmpio.c
./src/H5Fsec2.c
./src/H5Fsplit.c
./src/H5Fstdio.c
./src/H5MF.c
	The file access property list is passed to all H5F_low_...()
	functions and to the drivers.

./src/H5Fcore.c
	The block size can be set at run time on a per-file basis
	instead of at compile time across all files. The "5000 items in
	a group test" now takes 1.6 seconds.

./src/H5private.h
	Removed inclusion of mpi.h and mpio.h since they're included
	from H5public.h.

./src/H5Cpublic.h
./src/H5C.c
	Added H5Cset_stdio(), H5Cset_sec2(), H5Cset_core(),
	H5Cset_split(), and H5Cset_family() in addition to the
	H5Cset_mpio() that Kim and Albert already wrote.  We still
	need the H5Cget_driver() and an H5Cget...() counterpart for
	each of those functions.  The split and family drivers still
	need a little work but I'm checking this in anyway.

./config/irix64
	Added `-woff 1196' to get rid of errors about __vfork() being
	implicitly defined in a system header file.

./src/H5B.c
	Fixed a stack alignment problem.

Changes since 19980204
----------------------

./src/H5H.c
	Changed a temporary buffer from 20 bytes to 52 bytes.

./test/tfile.c
	Default sizes for file addresses and sizes are the same as
	sizeof(size_t) on the machine that creates the file.

Changes since 19980204
----------------------

./src/H5Odtype.c
	Compound data type names weren't aligned correctly. Thanks to
	Elena for finding this bug.

Changes since 19980203
----------------------
./src/H5F.c
	The default file addr and size sizes for new files are the
	same as sizeof(size_t) on the machine that creates the
	file. They used to always be 4.

./src/H5Pprivate.h
./src/H5Psimp.c
	Fixed `start' and `nelmts' arguments to be `size_t'.

Changes since 19980203
----------------------

./src/H5C.c
./src/H5Cprivate.h
./src/H5D.c
./src/H5Dpublic.h
	Added H5Dget_create_parms(), trying to stay one step ahead of
	Elena ;-)

Changes since 19980130
----------------------

./MANIFEST
	Added H5Fmpio.c.  One way to check that you've properly
	included new files is to run `./bin/release none', then unpack
	the resulting tar file somewhere and try to compile it.  The
	tar file will be ./releases/hdf-5.0.0a.tar.

./config/freebsd2.2.1
./config/linux
	Added `-ansi'

./acconfig.h
	Added definitions for PHDF5 and HAVE_PARALLEL.

./configure.in
	Added minimal support for parallel build.  Kim and Albert will
	have to flesh this out or I can do it if they're more specific
	about what they need.

./config/commence.in
	Added default value for $(RUNTEST)

./config/conclude.in
	`make test' uses value of $(RUNTEST) to run test cases.

./src/Makefile.in
	Added PARALLEL_SRC for conditional compilation of H5Fmpio.c

./src/H5D.c
./src/H5Dpublic.h
	Added H5Dget_type() for Elena


NOTE: These changes require that configure be rerun.  If you're using
      GNU make it will happen automatically, otherwise do it by
      hand.

./src/H5F.c
./src/H5T.c
./src/H5Tpublic.h
	Changed H5init() to H5open() and added an H5close() to fit our
	create/open/close paradigm.  The H5open() happens
	automatically on the first call to the HDF5 library.  The
	H5close() happens automatically on exit() (unless the app
	turns off that feature). H5close() closes all datasets and
	files and releases all resources used by the library.

./test/dsets.c
	Added calls to H5open() and H5close() to test them.

./test/dtypes.c
	Removed call to H5init() since we no longer need it there.

./src/H5Fstdio.c
	Changed the PABLO_MASK to the right value.  Thanks Kim.

Changes since 19980129
----------------------

./INSTALL
./INSTALL_MAINT
./README
	Updated installation instructions for hdf-5.0.0a.

./RELEASE
	Updated release notes.  Needs more work.

./bin/release
	The tarballs include the name of the root directory like
	hdf-5.0.0a so it doesn't have to be explicitly created when
	the files are extracted.
	

Changes since 19980129
----------------------

./config/freebds2.2.1
./config/irix64
./config/linux
	Added -DH5T_DEBUG to the debugging flags.  Also changed `true'
	to `:' for the Irix64 ranlib program.  This turns on printing
	of data type conversion statistics when the program exits.

./html/Datatypes.html
	Fixed documentation for data conversion functions and updated
	examples.

./src/H5D.c
	The I/O pipeline updates data type conversion statistics.

./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tpublic.h
	Cleaned up data type conversion registration interface.


Changes since 19980128
----------------------

./MANIFEST
	Added new files.

./bin/Makefile.dist		[NEW]
	This file becomes the default top-level Makefile which invokes
	configure with no arguments and then re-runs make.  It's for
	those people that don't read the INSTALL file.

./bin/release			[NEW]
	Build HDF release tarballs.  Arguments are a list of tarball
	types and are: tar, compress, gzip, or bzip2.  The default is
	gzip. If the only argument is `all' then all types of tarballs
	are created.  The results are put in the `releases' directory.
	Make sure you keep MANIFEST up to date.  This program requires
	perl-5.003 or better.

./src/H5AC.c
	Fixed a printf format.

Changes since 19980128
----------------------

./src/H5P.c
	Removed H5Pcreate()

./src/H5Psimp.c
	Copy int[] return value from H5P_get_hyperslab() to size_t[]
	argument to pass to other hyperslab functions.

./test/dsets.c
	Added a call to H5Eprint() to help track down Alberts O2k bug.

Changes since 19980128
----------------------

./MANIFEST
	Added new config files.

./src/H5private.h
	Changed FUNC_ENTER() so it calls H5Eclear() for all API
	functions but not for any private functions.  It also prints
	the names of all API functions on file 55 (just for the
	prototype) so we can get a list of API functions called with
	the Bourne shell commands like:

		./testhdf5 55>api_list		or
		./testhdf5 55>&1 1>/dev/null 2>&1 | less

	Otherwise the names are silently discarded.

./src/H5.c
./src/H5C.c
./src/H5D.c
./src/H5F.c
./src/H5G.c
./src/H5M.c
./src/H5P.c
./src/H5T.c
	Removed `H5ECLEAR' from lots of places in the source code.

./src/H5E.c
./src/H5Eprivate.h
	Recursion is a problem here, so to disable a call to
	H5Eclear() from FUNC_ENTER just define a local variable like
	this before you call FUNC_ENTER:

	     const H5E_clearable_g = FALSE;

	Unfortunately this results in a warning: declaration of
	`H5E_clearable_g' shadows global declaration.  Good thing it's
	only used in two places.

Changes since 19980128
----------------------

./config/conclude.in
	The maintainer-clean target removes Emacs backup files,
	mirroring backup and contrib files, core files, and profile
	output files in addition to what it used to remove.

./src/H5D.c
	Fixed a buffer allocation bug in the output pipeline.

./src/H5Gnode.c
	Fixed a comparison against size_t

./test/Makefile.in
	Added the other temporary h5 files to the `MOSTLYCLEAN' var.

./test/cmpd_dset.c
	Added four tests for partial I/O. Don't you just love it when
	something works on the first try!

Changes since 19980128
----------------------

./src/H5D.c
./src/H5Dpublic.c
	Added H5Dget_space().

./src/H5Gstab.c
./src/H5H.c
	Fixed a comparison with size_t against <0.

./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
	Changed `intn' to `int' for public function args and
	returns. H5Pget_hyperslab() returns the dimensionality.

./test/testhdf5.h
	Clears error stack more frequently.

./src/H5Psimp.c
./test/cmpd_dset.c
	Impelementing data space conversion.

Changes since 19980127
----------------------

./Makefile.in
./config/commence.in
	With GNU make you can now use `-j' and `-l' options and things
	get built correctly.  I can do a `make -j -l6 test' from a
	clean hdf5 source tree (after configure) in 45 seconds (8 to
	build dependencies, 26 to compile everything, and 11 to run
	the tests).

./src/H5Gnode.c
	Removed a comment that no longer applies.

./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
	Changed H5Pselect_hyperslab() to H5Pset_hyperslab() and added
	H5Pget_hyperslab() and H5P_get_hyperslab().

	Replaced a couple short memset() calls with a for loop.

	Removed `if (foo!=NULL)' from around H5MM_xfree() calls.

	Clear hslab_def when the hyperslab disappears.

./src/H5Tpublic.h
	Removed trailing enum comma.

Changes since 19980126
----------------------

./MANIFEST
	Added new files.

./config/linux
	Added `-pipe' to the default GCC flags since this is supposed
	to result in better performance on a multi-processor machine.

./html/Datasets.html
./html/dataset_p1.gif		[NEW]
./html/dataset_p1.obj		[NEW]
	Updated to match source.  The things which aren't part of the
	Feb-1 prototype are marked in bold. Added an example for
	partial I/O.

./html/Groups.html		[NEW]
./html/group_p1.gif		[NEW]
./html/group_p1.obj		[NEW]
./html/group_p2.gif		[NEW]
./html/group_p2.obj		[NEW]
./html/group_p3.gif		[NEW]
./html/group_p3.obj		[NEW]
	New documentation for groups.

./html/H5.sample_code.html
	Updated two examples to match code.

Changes since 19980123
----------------------

./src/H5D.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
./test/cmpd_dset.c
	Added support to turn background buffer on/off to help speed
	up conversions.  Currently, every type of conversion turns it
	off except compound-->compound conversions which always turn
	it on.  In the future the compound-->compound conversions
	might be more frugal.


Changes since 19980122
----------------------

./MANIFEST
	Added new files.

./src/H5D.c
	Added support for partial datatype I/O which is needed when
	merging struct members between file and disk.  This isn't the
	efficient version because the merge requires an extra gather
	(step 1b in my pipeline diagram) that isn't turned off when it
	isn't needed.

./src/H5T.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
	Conversion functions take an extra argument which is a pointer
	to a blob of private data that can be used by the conversion
	function to save anything that's expensive to compute and
	is constant for a particular conversion path.

./src/H5Tconv.c
	Compound data type conversion is beginning to work!  We can
	handle conversions between compound types that have members
	which are not arrays.  It also supports partial conversion so
	we can omit certain members of the source and not clobber
	extra members in the destination.

./test/Makefile.in
./test/cmpd_dset.c	[NEW]
	Added a test case that demonstrates how to use compound data
	types in a dataset.  The output doesn't match the output of
	the other test cases yet, the the entire example is more
	readable and written entirely with the API.


Changes since 19980122
----------------------

./src/H5.c
./src/H5B.c
./src/H5Bprivate.h
	Changed `new' to something else in 6 places for Fabio.

./src/H5T.c
./src/H5Tconv.c
	Beginning to work on compound data type conversion. Don't look
	yet :-)

Changes since 19980122
----------------------

./src/*.h
	Fixed indentation where indent(1) screwed up. This isn't by
	any means the final say, but it's better than it was.

./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
./src/H5C.c
./src/H5D.c
./src/H5E.c
./src/H5F.c
./src/H5G.c
./src/H5M.c
./src/H5P.c
./src/H5T.c
./src/H5Tconv.c
./src/debug.c
./test/dtypes.c
./test/istore.c
./test/theap.c
./test/tohdr.c
./test/tstab.c
	Removed some atom functions from the API and made them
	library-scope. Also changed some names by removing the
	redundant `atom' from the name and by adding a `_' after the
	`H5A'.

Changes since 19980121
----------------------

./Makefile.in
	Added more dependencies to .PHONY.

./src/H5D.c
	The write side of the I/O pipeline is implemented now too.
	Things are looking good for the prototype and it's just a
	matter of populating the library with the data type and data
	space conversion functions.

./src/H5Farray.c
./src/H5Fprivate.h
./test/istore.c
	Changed the order of the arguments for H5F_arr_read() and
	H5F_arr_write().

./src/H5P.c
./src/H5Pprivate.h
	Changed the names of the arguments of H5P_find().  Fleshed out
	the mgath and fscat callback types.

./src/H5Psimp.c
	Added stubs for H5P_simp_mgath() and H5P_simp_fscat() that
	operate on the entire data space.  Quincey, once you have the
	data space hyperslab stuff in place let me know and I'll
	finish the H5P_simp_*() functions to do partial I/O.  Or you
	can take a look at it too if you like; there's some comments
	in there for you.

./src/H5V.c
./src/H5Vprivate.h
	Changed dimensionality arguments from `size_t' to `intn' to be
	consistent with the rest of the library and to get rid of
	warnings on 64-bit Irix.

Changes since 19980121
----------------------

./MANIFEST
./src/H5Psimp.c		[NEW]
./src/Makefile.in
	Added H5Psimp.c and populated it with some conversion
	functions. Eventually the parts of H5P.c that operate on
	simple data spaces will be migrated to H5Psimp.c and other
	files will be created for other types of data spaces.

./src/H5D.c
	The read pipeline, H5Dread(), has been updated to handle data
	space conversion although the actual simple data space
	conversion functions don't do anything yet. But we're getting
	really close!

./src/H5P.c
./src/H5Pprivate.h
	Added H5P_find() to locate data space conversion functions.
	Added typedefs for structs related to data space conversion.


Changes since 19980120
----------------------

./src/H5D.c
	Fixed a rather major bug when reading/writing a chunked dataset.

Changes since 19980116
----------------------

./src/H5AC.c
./src/H5ACprivate.h
./src/H5B.c
./src/H5D.c
./src/H5Farray.c
./src/H5Fprivate.h
./src/H5V.c
./src/H5Vprivate.h
	Fixed indent oopses.

./src/H5D.c
./src/H5Fprivate.h
./src/H5Farray.c
./test/istore.c
	We can now perform partial I/O on contiguous storage
	transferring between a hyperslab of file storage and a
	hyperslab of memory.  However, partial I/O hasn't been added
	to the I/O pipeline yet in H5D.c

Changes since 19980114
----------------------

./html/Datasets.html
	Removed some archaic comments about data spaces. Fixed example
	code.

./MANIFEST
./html/H5.format.html
./src/H5O.c
./src/H5Oprivate.h
./src/H5Ocstore.c		[DELETED]
./src/H5Oistore.c		[DELETED]
./src/H5Olayout.c		[NEW]
./src/Makefile.in
./test/istore.c
	Replaced H5O_CSTORE and H5O_ISTORE messages with a more
	general H5O_LAYOUT message.

./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpublic.h
	A little more work on the pipeline.  Access to the file data
	is through the new H5F_arr_read() and H5F_arr_write() which do
	I/O on hyperslabs of byte arrays and don't depend on data
	layout.  This should simplify the I/O pipeline quite a bit.

	I also added another argument to H5Dread() and H5Dwrite() to
	describe the hyerslab of the file array on which I/O is
	occuring. We discussed this at last week's meeting.

./src/H5Farray.c		[NEW]
	Added functions that sit on top of H5F_block_read() and
	H5F_istore_read() and implement a common set of functions
	between all layouts.  This means I/O of hyperslabs of
	byte-arrays in the file to arrays of bytes in memory.  When
	operating on arrays of elements (>1byte) then we just add
	another dimension.  That is, a 10x20 array of int32 becomes a
	10x20x4 array of bytes.

	[This is the area I'll be working on most of next week to
	implement partial I/O for contiguous data and to improve
	performance for chunked data.]

./src/H5Fistore.c
./src/H5Fprivate.h
	Replaced the H5F_istore_t data type with the layout message
	H5O_layout_t which looks almost the same.  Eventually I'd like
	to rename `istore' to `chunked' everywhere and use `istore'
	for 1-d storage where the chunks are all different sizes like
	in the small object heap where each object is a chunk.

./src/H5V.c
	Changed ISTORE to LAYOUT in one place.

./test/dsets.c
	Fixed for extra argument to H5Dread() and H5Dwrite().



Changes since 19980108
----------------------

./MANIFEST
./src/H5Dconv.c		[REMOVED]
./src/H5Tconv.c		[NEW]

	Supports data type conversion.

./src/H5Odtype.c
./src/H5Tpkg.h

Changes since 19980107
----------------------

./html/Datatypes.html
	Updated to match code.

./src/H5Odtype.c
./src/H5Oprivate.h
./src/H5Tpkg.h

	Changed H5T_FIXED to H5T_INTEGER.

./src/H5T.c
./src/H5Tprivate.h
./src/H5Tpublic.h
./test/dtypes.c
	Implemented lots of type properties.

./src/H5detect.c
./src/H5Tpublic.h
	It is no longer necessary to call H5init() before using a
	predefined data type.

Changes since 19980105
----------------------

./config/freebsd2.2.1
./config/linux
	Added -UH5O_DEBUG to the debug flags.  Turn this on to get
	lots of lines on stderr to show what objects are opened and
	closed.

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

./src/H5D.c
./src/H5Dpublic.h
./src/H5Gstab.c
./src/H5O.c
./src/H5Ocont.c
./src/H5Ocstore.c

./src/H5Oistore.c
./src/H5Oname.c
./src/H5Onull.c
./src/H5Oprivate.h
./src/H5Osdspace.c
./src/H5Ostab.c
./src/H5P.c
./src/istore.c
./test/tohdr.c
	Object header functions now understand constant
	vs. non-constant messages.

./src/H5F.c
./src/H5Fprivate.h
	The file OID can be closed before other OID's.

./src/H5Flow.c
	H5F_addr_defined() is a macro in this file.

./src/H5G.c
./src/H5Gpublic.h
./test/tstab.c
	A current working group cannot be deleted.

./src/H5Gent.c
./src/H5Gpkg.h
	Removed unused functionality.

./src/H5public.h
	Includes <sys/types.h> for size_t.
	

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/H5Fprivate.h
	Simpler handling of special case files: empty files and files
	with a single object.

./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gpublic.h
./src/H5Gshad.c		(DELETED)
./src/H5Gstab.c
./src/Makefile.in
	Removed shadows, simplifying code.  Symbol table entries are
	allowed to cache only constant meta data.  Fixed naming.

./src/H5O.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.


Changes since 19971216
----------------------

./html/Datatypes.html
	Fixed some spelling errors, added information from 12/19
	developers' meeting, added compound data types defined in
	terms of other compound data types.

./html/H5.format.html
	Some formatting changes and some minor updating.

./src/H5ACprivate.h
	Removed some debugging fields from a struct when debugging is
	turned off.

./src/H5H.c
	Reformatted a couple long lines.

./test/istore.c
	Flipped a couple constants for testing. Nothing important.

Changes since 19971211
----------------------

./html/Datasets.html
	Updated from Friday's discussion.

./html/Datatypes.html
	Ready for review.

./html/H5.format.html
	Updated boot block to match source. Removed unused object
	header messages.

./src/H5.c
	Changes to error handling.

./src/H5B.c
	Increased size of internal static buffers.

./src/H5C.c
	Fixed syntax error when NDEBUG is defined.

./src/H5E.c
./src/H5Eprivate.h
./src/H5Epublic.h
	Errors can now be printed with H5Eprint().  Other minor
	changes to names and arg types.

./src/H5F.c
	The base address is now stored in the boot block.  The user
	block size and the base address are synonyms.

./src/H5Fstdio.c
	Fixed a bug with a return value from fseek().

./src/H5H.c
	Added alignment constraints to get rid of unaligned access
	errors on the DEC alpha having to do with the heap free list.

./src/H5P.c
./src/H5Ppublic.h
	Changed some size arguments from int to size_t and fixed
	memory allocation calls.

./src/H5T.c
./src/H5Tpublic.h
	Changed the order of functions so all the public ones are at
	the top of the file.  Other minor changes.

./src/H5detect.c
	Added a newline to a string constant.

./test/dsets.c
./test/dtypes.c
./test/hyperslab.c
./test/istore.c
	Added a definition for __FUNCTION__.  Changed a couple
	variable types.

./test/testhdf5.h
	The error stack is printed when something goes wrong.

Changes since 19971211
----------------------

./MANIFEST
./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/H5B.c
./src/H5C.c
./src/H5D.c
./src/H5E.c
./src/H5Eprivate.h
./src/H5Epublic.h
./src/H5F.c
./src/H5Fcore.c
./src/H5Ffamily.c
./src/H5Fistore.c

./src/H5Fsplit.c
./src/H5Fstdio.c
./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gshad.c
./src/H5Gstab.c
./src/H5H.c
./src/H5M.c
./src/H5MF.c
./src/H5O.c
./src/H5Osdtyp.c (./src/H5Odtype.c)
./src/H5P.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.

./html/Datasets.html
	Updated the example to use H5Cset_prop().

Changes since 19971210
----------------------

./MANIFEST
	Removed H5config.h since it's generated from H5config.h.in.

./src/H5C.c
./src/H5Cprivate.h
	Changed H5Csetparm() to H5Cset_prop() and changed it to pass
	property values by value instead of reference.  Changed
	H5Cgetparm() to H5Cget_prop().  Changed data types of file
	creation properties so the application can use `int' or
	`size_t' for most properties.  Properties and their types are
	documented in H5Cget_prop().

	Changed H5C_class() to H5Cget_class() to make the naming more
	uniform across packages.

./src/H5Cpublic.h
	Changed names of properties to make them more uniform across
	packages: H5F_USERBLOCK_SIZE became H5F_SIZEOF_USERBLOCK,
	H5F_OFFSET_SIZE became H5F_SIZEOF_ADDR, H5F_LENGTH_SIZE became
	H5F_SIZEOF_SIZE.

./src/H5D.c
./src/H5Dprivate.h
	Added support for chunked data storage.  There still isn't any
	support for data type conversion or data space conversion, so
	chunked storage doesn't do much at this time.

./src/H5E.c
./src/H5Epublic.h
	Added the H5E_TEMPLATE major error number.  I'm about the
	change the HGOTO_ERROR() and HRETURN_ERROR() macros to take an
	error string as an additional argument instead of specifying
	it as a comment.

./src/H5Fistore.c
	Added `const' to the `buf' argument of H5F_istore_write()
	although this temporarily causes a compiler warning.

./src/H5Fprivate.h
	Changed data types of certain file-related variables from
	types like `uint8' to `uintn' since the library data types
	should not depend on the file data types.

./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
	Moved H5Pget_lrank() to H5Pget_ndims(), and H5Pget_ldims() to
	H5Pget_dims() to make naming more uniform.  Dimensions should
	always be of type `size_t'.  Similarly for H5P_get_lrank() and
	H5P_get_ldims().

./test/dsets.c
	Added test for creation of chunked datasets.

./test/dsets.c
./test/istore.c
./test/tfile.c
	Template changes.

./test/th5p.c
	Accommodated changes to H5P.

Changes since 19971114
----------------------

./MANIFEST
	Added/removed files

./config/conclude.in
	Added ability to clean other files.  The extra files to remove
	should be listed in a make variable with the same name as the
	target.  For instance, $(MOSTLYCLEAN) is a list of files in
	addition to the normal files that should be removed when the
	user types `make mostlyclean'.

./html/Datasets.html		NEW
	Documents the dataset interface (H5D).

./html/Datatypes.html	        NEW
	Documents the data type interface (H5T).

./html/H5.format.html
./html/storage.html
	Updated to reflect source changes, including the data type
	message.  The byte layout tables were also reformatted
	slightly.

./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.

./test/Makefile.in
	Added new tests.

./test/dsets.c		NEW
	Tests datasets.

./test/dspace.c	NEW
	Tests data spaces.

./test/dtypes.c		NEW
	Tests data types.

./test/istore.c
./test/tfile.c
./test/th5p.c
./test/theap.c
./test/tohdr.c
	Changed to work with new function names.

./test/testhdf5.c
	Removed the data type and dataset tests since they're now in
	their own files. They had to be rewritten because of extensive
	changes to those interfaces.


Changes since 19971106
----------------------

./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/H5B.c
./src/H5Bprivate.h
./src/H5C.c
./src/H5D.c
./src/H5F.c
./src/H5Fcore.c
./src/H5Fistore.c
./src/H5Flow.c
./src/H5Fprivate.h
./src/H5Fsec2.c
./src/H5Fstdio.c
./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gshad.c
./src/H5Gstab.c
./src/H5H.c
./src/H5Hprivate.h
./src/H5MF.c
./src/H5MFprivate.h
./src/H5O.c
./src/H5Ocont.c
./src/H5Oistore.c
./src/H5Oprivate.h
./src/H5Ostab.c
./src/H5Ostdst.c
./src/H5pivate.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/H5D.c
./src/H5F.c
./src/H5Ffamily.c
./src/H5Fistore.c
./src/H5Flow.c
./src/H5Fprivate.h
./src/H5Fsec2.c
./src/H5Fstdio.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.

Changes since 19971024
----------------------

./config/linux
./config/freebsd2.2.1
	Rewritten to be more flexible.

./src/H5AC.c
./src/H5ACprivate.h
./src/H5F.c
./src/H5H.c
./src/H5Gpkg.h
./src/H5Gshad.c
./src/H5O.c
./test/istore.c
./test/tstab.c
	Accumulates cache statistics and displays the results on
	stderr when the file is closed if it was opened with
	H5F_ACC_DEBUG passed into H5F_open()

./src/H5B.c
./src/H5Bprivate.h
./src/H5Fistore.c
./src/H5Gnode.c
	Added more debugging which is turned on if H5B_DEBUG is
	defined on the compile command (see config/linux).

	Fixed a couple of bugs with left insertions which are used by
	the indexed storage stuff.

./src/H5Flow.c
	Fixed a memory leak.

./src/H5Fprivate.h
	Fixed warnings about shifting more than size of object.

./src/H5Fstdio.c
	Fixed seek optimizations back to the way Quincey originally
	had them.

./src/H5V.c
	Removed unused variables.


Changes since 19971023
----------------------

./config/conclude.in
	Test work when `.' isn't in $PATH.

./src/H5F.c
./src/H5Fcore.c		NEW
./src/H5Flow.c
./src/H5Fprivate.h
./src/H5Fsec2.c
./src/H5Fstdio.c
./src/Makefile.in
./MANIFEST
	Added the in-core temporary file driver as an exercise to
	clean up some of the H5F package.  It speeds up `testhdf5 -o
	stab' by 25 percent!  If you want to try it you'll need to
	recompile everything with `-DH5F_LOW_DFLT=H5F_LOW_CORE'.
	Don't expect testhdf5 to ever work since creating a file,
	closing it, and then opening it for read-only will fail.

Changes since 19971021
----------------------

./MANIFEST
./src/Makefile.in
	Added new files.

./html/H5.apiv2.html
	Added documentation for group stuff.

./src/H5private.h
./src/H5E.c
./src/H5Epublic.h
./src/H5F.c
./src/H5Flow.c			NEW
./src/H5Fprivate.h
./src/H5Fsec2.c			NEW
./src/H5Fstdio.c		NEW
	Low-level file driver is selected at runtime.

./src/H5Fprivate.h
	Got rid of `shift >= sizeof operand' warnings on big endian
	machines.

./src/H5Fistore.c
./test/istore.c
	Still working on indexed storage...

./src/H5H.c
./src/H5Hprivate.h
	Removed alignment constraints.

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/Makefile.in
./test/Makefile.in
	New source files.

./src/H5A.c
./src/H5Apublic.h
./src/H5C.c
	Changed VOIDP to void* in a couple places.

./src/H5AC.c
./src/H5ACprivate.h
./src/H5B.c
./src/H5Bprivate.h
./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
./src/H5O.c
	Added an extra argument to H5AC_find_f() and H5AC_protect(). This
	arg gets passed to the load() method.  Also added an extra
	argument to the H5AC_find() macro.

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

./src/H5Fprivate.c
./src/H5Fistore.c (new)
	Added indexed I/O operations.

./src/H5G.c
./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/H5Bprivate.h
./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
./src/H5E.c
./src/H5Epublic.h
./src/H5F.c
./src/H5Fprivate.h
./src/H5G.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gpublic.h
./src/H5Gshad.c
./src/H5Gstab.c
./test/stab.c
	Changed `directory' to `group' in numerous places.

./src/H5private.h
	The FILELIB constant can be set on the compile command-line.

./src/istore.c		     NEW
	Tests for indexed storage.


Changes since 19970915
----------------------

./src/H5Apublic.h
	Removed H5_OID.

./src/H5D.c
	Fixed a few things to work better with symbol tables. Combined
	the H5D_oid_t and H5D_dataset_t structs.

./src/H5Dprivate.c
	Combined the H5D_oid_t and H5D_dataset_t types.

./src/H5M.c
	Removed the callback list for H5_OID.

./test/th5d.c
	Changed the H5Mfind_name() return value and removed the call
	to H5Maccess().

./test/th5p.c
	Removed unused variables.

Changes since ????????
----------------------
./src/H5G.c
	Fixed an error in H5G_namei() that ignored the object name
	when the object was the only thing in a file.

./test/th5d.c
	Changed and object name for a read request.

Changes since 19970813
----------------------

./html/H5.format.html
	Changed the format of the boot block to get rid of the B-tree
	size and replace it with K values for the various types of
	B-trees.

./src/H5B.c
./src/H5Bprivate.h
	The B-tree K value comes from a combination of the B-tree
	subclass and the file.

./src/H5C.c
./src/H5F.c
./src/hdf5lims.h
./src/hdf5type.h
	Removed the B-tree size parameter and added an array of B-tree
	K values.  Also added symbol table node K value.

./src/H5Eprivate.h
./src/H5Eproto.h
	Added H5E_LINK for errors involving link counts.

./src/H5G.c
	Inserting something into a directory with H5G_insert()
	increments the link count in the object header.  The root
	object should always have a link count of at least 1.

./src/H5Gnode.c
./src/H5Gprivate.h
	The symbol table node K value comes from the file instead of
	being a constant.

./src/H5Olink.c
	Added an assert(), fixed a hard-link bug.

./test/tfile.c
	Removed tests for H5_BTREEPAGE_SIZE and added tests for
	H5_SYM_LEAF_K and H5_SYM_INTERN_K.

./test/tstab.c
	Removed call to H5O_link() since it's handled by H5G_insert().



Changes since 19970812
----------------------

Changes since 19970811
----------------------

./src/H5AC.c
	We sort the cache before a complete flush because it might be
	more efficient to write things back to disk in order of
	increasing address.  If you want the old way then undef the
	SORT_BY_ADDR constant at the top of H5AC.c  I haven't
	determined which systems and I/O libraries this helps or
	hurts. (This is currently off because of a bug I need to track
	down that causes qsort() to run for a really long time).
	
./src/H5B.c
	Fixed a couple more bugs.

./src/H5Eprivate.h
./src/H5Eproto.h
	Added major H5E_DIRECTORY and minor H5E_EXISTS, H5E_COMPLEN.

./src/H5G.c
	Added directory-aware functions.

	The heap and B-tree are created when a directory is created
	instead of when the first symbol is added.  This simplifies
	symbol table entry caching for the directory since the cached
	value never changes now.

./src/H5Gnode.c
./src/H5Gprivate.h
	Fine tuned the B-tree K values for symbol tables assuming an
	average number of symbols is about 100 per directory.  The
	tuning minimizes storage space.

	Fixed a return value in H5G_node_cmp().

./src/H5H.c
./src/H5Hprivate.h
	Moved some macros the the header file.

./src/H5O.c
./src/H5Ocont.c
./src/H5Onull.c
./src/H5Ostab.c
	Changed the arguments for the decode method for messages.  The
	second argument is the raw message size.

	Added a class variable for native message size.

	Added H5O_reset() to free memory used internally by a message.

./src/H5Oname.c			NEW
./src/H5Oprivate.h
./src/Makefile
	The object name message.

./src/hdf5port.h
	Added defn for HDstrdup()

./test/tfile.h
	Removed unused local variables.

./test/tstab.c
	Now uses directory-aware functions which in turn call the
	unaware functions.

Changes since 19970808
----------------------

./src/H5B.c
./src/H5Bprivate.h
./src/H5G.c
	H5B_new() only takes two arguments.

./src/H5C.c
	Fixed initializer for default_file_create to be the same order
	as it's definition.

./src/H5D.c
	Changed commented-out code to #if 0/#endif.  #if'd out a
	variable that was unused because of #if'd out code.

./src/H5Dproto.c
	Added a prototype for H5Dwrite().

./src/H5F.c
	Changed parentheses to fix precedence problems from:

		flags & (~H5AC_OVERWRITE) != 0
	to
		(flags & ~H5AC_OVERWRITE) != 0

./src/H5H.c
	Heap reallocation doubles the heap size instead of tripling it.

./src/H5O.c
	Got rid of a statement with no effect.

./src/hdf5port.h
	Indented a few #defines.  Added a defn for MAX3().


Changes since 19970807
----------------------

./src/H5AC.c
	Renamed H5AC_find() to H5AC_find_f() which is invoked from the
	H5AC_find() macro.

	Changed HASH() to H5AC_HASH().

./src/H5ACprivate.h
	Increased the number of cache slots from 1033 to 10330 to see
	how it affects performance.  This should probably be
	changeable on a per-file basis.

./src/H5B.c
	Fixed some bugs now that symbol tables are actually using the
	stuff.

	Improved debugging a little.

	Fixed uninitialized memory appearing in the file.

./src/H5D.c
	Changed a FUNC_ENTER() argument from H5Dset_info to H5Dwrite.

./src/H5F.c
	Plugged a memory leak in H5F_dest().

./src/H5G.c
./src/H5Gprivate.h
	Many of these functions take a symbol table entry which
	describes the symbol table rather than just the symbol table
	address.

	Moved some functions to make room for the ones that understand
	directory names: 
		  H5G_new()	-> H5G_stab_new()
		  H5G_find()	-> H5G_stab_find()
		  H5G_modify()	-> H5G_stab_modify()
		  H5G_insert()	-> H5G_stab_insert()
		  H5G_list()	-> H5G_stab_list()

./src/H5Gnode.c
	Added more assertions.

	Zero new memory so junk doesn't appear in the data file.  This
	is a problem when one tries to declassify a classified data
	file.

	H5G_node_debug() can take an extra argument which is the
	address of the heap for the symbol table.  If supplied, the
	symbol names are printed along with the heap offsets.

./src/H5H.c
./src/H5Hprivate.h
	Fixed a bug with the free blocks by forcing things to align on
	even boundaries.  It's still possible to lose heap memory if
	the hole is smaller than the free list header.  The
	alternative is to align heap objects on 12 or 20 byte
	boundaries, but this tends to waste to much space.

	Zero new memory like with H5Gnode.c.

	Fixed a "mispeling" of NDEBUG.

./src/H5Ocont.c
./src/H5Onull.c
	Added the pablo mask defn.

./src/H5Ostab.c
	Added the pablo mask defn.

	Fixed a read from uninitialized memory.

./src/H5Oprivate.h
	Tuned some parameters to see how they affect performance.

./src/debug.c
	An optional third argument can be supplied which is the
	address of a heap to use to display names in a symbol table.

./src/hdf5pabl.h
	Changed `int' to `intn'.

./src/hdf5plat.h
	Added defn for int64 and uint64 on irix.  It seems to be
	wrong, but at least things compile and run.  This file will go
	away with autoconf anyway.

./test/testhdf5.c
./test/Makefile
	Added tstab.c

./test/testhdf5.h
	Added tstab.c

	Fixed bugs with CHECK_I() and CHECK_PTR().		  


Changes since 19970804
----------------------

./html/H5.format.html
	Added documentation for the symbol table message, 0x0011.

./src/H5AC.c
./src/H5ACprivate.h
./src/H5ACproto.h
./src/H5Bproto.h
./src/H5Gproto.h
./src/H5Hproto.h
./src/H5MFprivate.h
./src/H5MFproto.h
./src/H5MM.c
./src/H5MMprivate.h
./src/H5MMproto.h
	Changed my e-mail address.

./src/H5O.c		  NEW
./src/H5Onull.c		  NEW
./src/H5Ocont.		  NEW
./src/H5Ostab.c		  NEW
	New functions for dealing with object headers.  The H5O.c is
	the generic stuff, and each particular message has a source
	file for the specific stuff.

	Use ./src/H5Ostab.c as a model for implementing other messages.

./src/Makefile
./src/test/Makefile
	Added new files

./src/debug.c
	Added debugging calls for object headers.

./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
./src/H5MF.c
	Changed my e-mail address.

	Improved error handling.

./src/H5Eprivate.h
./src/H5Eproto.h
	Added more error symbols

./src/H5F.c
	Changed my e-mail address.

	Used macros for sizeof offsets and lengths.

	Added the interface initialization function to
	H5F_block_read() and H5F_block_write().

	Updated H5F_debug()

./src/H5Fprivate.h
	Got rid of H5F_symbol_table_size().  Use H5G_SIZEOF_ENTRY()
	instead.

	Reformatted H5F_decode_offset() for readability.

./src/H5G.c
	Changed my e-mail address.

	Improved error handling.

	Replaced not_implemented_yet__*() with real functions from
	H5O.

./src/H5Gprivate.h
	Changed `symtab' to `stab' to be consistent with other stuff.

./src/H5H.c
./src/H5Hprivate.h
	Changed my e-mail address.

	Improved error handling.

	Added an extra argument to H5H_new() to indicate whether you
	want a global heap or a local heap.

./src/hdf5gen.h
	Added NELMTS()

	Fixed FUNC_ENTER()

	Rewrote FUNC_LEAVE() in terms of HRETURN().

./src/hdf5meta.h
	Added `const' to the decode macros.

./src/hdf5pabl.h
	Added PABLO_SAVE()

./test/testhdf5.c
./test/testhdf5.h
	Added calls for object header testing.

./test/theap.c
	Turned off some output.

Changes since 19970804
----------------------

./html/H5.format.html
	Indented the first few hundred lines as I cleaned some stuff
	up.

./src/H5.c
	Added an `_g' to the end of library_initialize,
	thread_initialize, and interface_initialize to abide by the
	naming convention.  Removed setting of these variables from
	the various initialization functions since it happens in the
	FUNC_ENTER() macro now.

	Defined PABLO_MASK.

	Removed `CONSTR(FUNC,"function_name")' everywhere since it's
	handled by the various FUNC_ENTER macros.

	Fixed calls to FUNC_ENTER(), FUNC_LEAVE(), and HRETURN_ERROR()
	so they don't need so many arguments.

	Changed PABLO_TRACE_ON() to FUNC_ENTER() since there is no
	longer any danger of infinite recursion.

	H5_term_library() now returns SUCCEED/FAIL and uses
	FUNC_ENTER/FUNC_EXIT macros.

./src/H5A.c
	Changes similar to H5.c.

	Most (all?) of the functions called PABLO_TRACE_ON() and the
	package doesn't have an interface initializer that I can see,
	so the second argument to FUNC_ENTER() is always NULL.

	H5A_release_atom_node() returns SUCCEED/FAIL.

./src/H5AC.c
	Added error handling.

	Arguments for internal functions are checked with assert().

./src/H5C.c
	Changes similar to H5.c

	Fixed the FUNC variable in H5C_get_default_atom() since it was
	initialized to the wrong name.

./src/H5D.c
	Changes similar to H5.c

./src/H5E.c
	Changes similar to H5.c

	Changed the pablo mask from H5_mask to H5E_mask in
	H5E_init_interface().

	H5Eclear(), H5E_store(), and H5Epush() return SUCCEED/FAIL.
	Changed PABLO_TRACE_OFF() calls to FUNC_LEAVE() calls in the
	same functions.

./src/H5Eprivate.h
./src/H5Eproto.h
	Added additional error symbols for the H5AC package.

	Changed prototypes for H5Eclear() and H5Epush().

	Changes to HRETURN_ERROR() and HGOTO_ERROR() to reduce the
	number of arguments.

./src/H5F.c
	Changes similr to H5.c

	Changed the pablo mask from H5_mask to H5F_mask for the
	FUNC_LEAVE() call of H5F_init_interface().

	Added FUNC_ENTER() and FUNC_LEAVE() calls to some functions
	that didn't have them.

./src/H5M.c
	Changes similar to H5.c

	Fixed the FUNC variable in H5M_init_interface() since it was
	initialized to the wrong name.

./src/H5P.c
	Changes similar to H5.c

./src/H5T.c
	Changes similar to H5.c

./src/hdf5gen.c
	Changes to FUNC_ENTER() and FUNC_EXIT() to reduce the number
	of arguments.  FUNC_ENTER() is now safe from infinite
	recursion since it updates the library_initialize_g,
	thread_initialize_g, or interface_initialize_g variables
	before calling the appropriate initialize function.


Changes since 19970731
----------------------

./src/H5AC.c
	Fails sooner if the type of object requested doesn't match
	the type of object cached.

./src/H5B.c
./src/H5Bprivate.h
./src/H5Fprivate.h
./src/H5G.c
./src/H5Gnode.c
./src/H5Gprivate.h
./src/H5H.c
./src/H5Hprivate.h
	Changed lots of `H5*_HDR_SIZE' macros to `H5*_SIZEOF_HDR' to make
	things more consistent.

	Added H5*_SIZEOF_MAGIC macros.

	Added debugging functions to some of the packages.

./src/H5F.c
	Fixed a bug with reading past the end of a buffer.

./src/H5Tproto.h
	Added prototypes for H5Tadd_field() and H5Tget_fields().

./src/debug.c
	Low-level file debugging program.

./src/Makefile
	Builds `debug' as one of the main targets.  The target is
	called `debug_hdf5' so it doesn't conflict with the `debug'
	target that was already there.  But the executable is called
	`debug'.




Changes since 19970718
----------------------

./src/H5B.c
./src/H5G.c
./src/H5Gnode.c
./src/H5H.c
	Changed SIZEOF_OFFSET and SIZEOF_SIZE to H5F_SIZEOF_OFFSET and
	H5F_SIZEOF_SIZE.  Modified files to use these instead of
	accessing the hdf5_file_t struct directly.

	Changed address return values from H5B to -1 for error.

	Changed off_t to haddr_t for anything that's a file address.


Changes since 19970718
----------------------

./src/GNUmakefile
./src/Makefile
	Added H5G.c

./src/H5F.c
	Moved creation and destruction of hdf5_file_t structs into
	H5F_new() and H5F_dest() since these tasks are becoming more
	and more complicated.

./src/H5Fprivate.h
./src/H5Gprivate.h
	Moved the h5_symbol_type_t and h5_symentry_t typedefs to
	H5Gprivate.h and called them H5G_type_t and H5G_entry_t.

./src/H5Gnode.c
	Now uses H5G_entry_t in a way that makes it easy to change the
	definition of that structure.

./src/H5H.c
	Changed the size hint code so that if you don't give a size
	hint, it's less likely that 8 bytes of the file are
	wasted. Also fixed some debugging code so it doesn't dump
	core.

./src/H5MF.c
	Freeing something of zero length, or freeing something with a
	file address of zero or negative, is a no-op.


Changes since 19970716
----------------------

./html/H5.format.html
	Added documentation for the small heap object with some notes
	about using B-link trees for large heaps.  Also updated the
	symbol table stuff to reflect recent changes to the source
	code.

./src/GNUmakefile
./src/Makefile
	Added small heaps.

./src/H5.c
./src/H5AC.c
./src/H5ACprivate.h
./src/H5ACproto.h
./src/H5B.c
./src/H5Bprivate.h
./src/H5Bproto.h
./src/H5Cprivate.h
./src/H5F.c
./src/H5Fprivate.h
./src/H5Gnode.c
./src/H5Gprivate.h
./src/H5Gproto.h
./src/H5MFprivate.h
./src/H5MFproto.h
./src/H5MMprivate.h
./src/H5MMproto.h
./src/H5private.h
	Fixed include files. The H5*.c file contains constants,
	typedefs, and prototypes for things with file scope.  The
	H5*private.h file contains things with library scope.  The
	H5*proto.h file contains things with API scope.

	The H5*private.h file should include H5*proto.h.  The H5*.c
	file should include any H5*private.h files it needs.

./src/H5MF.c
	Implemented H5MF_alloc() and a stub for H5MF_free().

./src/H5MM.c
	Added `const' to an argument.

./test/Makefile
./test/testhdf5.c
./test/testhdf5.h
./test/theap.c
	Added heap tests.


Changes since 19970713
----------------------

./src/H5AC.c
./src/H5ACprivate.h
./src/H5ACproto.h
./src/H5B.c
./src/H5Bprivate.h
./src/H5Bproto.h
	No longer need to initialize H5AC or H5B at run time.

./src/H5F.c
	Second argument to H5AC_flush changed.

./src/H5MM.c
	uses H5MM_xstrdup

./src/Makefile
	Added H5Gnode.o

./src/hdf5port.h
	Added HDmemmove

./src/H5Gnode.c
./src/H5Gprivate.h
./src/H5Gproto.h
	Symbol table stuff.  The H5Gnode.c file contains functions for
	dealing with symbol table nodes.  This code isn't complete
	yet, so ignore the warnings for implicit function declarations
	and casting of integer to pointer.


Changes since 19970710
----------------------

./src/Makefile
	Added new source files.

./src/hdf5file.c
./src/h5proto.h
	Added H5F_block_read() and H5F_block_write() convenience functions
	that seek and then read/write.

./src/hdf5.c
	Added includes for cache and B-link trees.

./src/hdf5.h
	Removed include for cache.

./src/hdf5file.h
	Added the H5FPdecode_offset macro (and then removed it :-)

./src/H5AC		NEW
./src/H5ACprivate.h     NEW
./src/H5ACproto.h       NEW
	Cache files.  H5AC.c was renamed from hdf5cache.c and
	H5ACprivate.h was renamed from hdf5cache.h.

./src/H5B.c             NEW
./src/H5Bprivate.c      NEW
./src/H5Bproto.c        NEW
	B-link tree functions.  Not tested yet since we don't have
	anything that gets pointed to by a B-tree.

./src/H5MF.c	        NEW
./src/H5MFprivate.h     NEW
./src/H5MFproto.h       NEW
	File memory management functions needed by B-link trees but
	not fully implemented.

./src/H5MM.c	        NEW
./src/H5MMprivate.h	NEW
./src/H5MMproto.h	NEW
	Core memory management functions same as the HD... macros but
	assert that memory was allocated.  Also fixes problems with
	some versions of realloc().
	
Changes since 19970709
----------------------

./src/hdf5cache.c	NEW
./src/hdf5cache.h	NEW
	Implements a memory cache for objects that exist in the HDF5
	file.  All exported symbols begin with `H5AC_'.

./src/hdf5file.c
	The cache is created and destroyed when the hdf5 file structure
	is created and destroyed.  The cache is flushed when H5Fclose()
	is called and the reference count is zero.

./src/hdf5file.h
	The hdf5_file_t struct has a cache.
		
./src/hdf5.h
	Includes hdf5cache.h

./src/h5proto.h
	Added function prototypes from hdf5cache.c

./src/Makefile
	Added hdf5cache.o as a library object.
