./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.

a2b8da49db [svn-r1032] 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 termal escape sequences
	because it's sometimes possible to execute commands that way.

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

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

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

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

./src/H5Vprivate.h
./src/H5Zpublic.h
./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'.

46f683cf14 [svn-r876] 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.

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

./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.

c8d2f1e17a [svn-r537] 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
