./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.

	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)

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

./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:
		    (0) "U struct complex { double R; double I; };\012V"
		    (43) " double;\012"
	    U                         0:0:0:2500           Dataset {256/512}
		Data: printing of compound data types is not implemented yet
	    V                         0:0:0:3928           Dataset {256/512}
		Data:
		    (0) 0, 0.015625, 0.03125, 0.046875, 0.0625,
		    (5) 0.078125, 0.09375, 0.109375, 0.125, 0.140625,
		    (10) 0.15625, 0.171875, 0.1875, 0.203125, 0.21875,
		    (15) 0.234375, 0.25, 0.265625, 0.28125, 0.296875,

29a029d7e7 [svn-r529] 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.

b56f011989 [svn-r526] 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.

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

./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.

1dbacc8377 [svn-r517] 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.

79d65106ab [svn-r514] 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.
