2bfbf4f707 [svn-r773] 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.

311e4c9ebf [svn-r720] Changes since 19980922
----------------------

./src/H5F.c
./src/H5Fprivate.h
./src/H5P.c
./src/H5Ppublic.h
./test/chunk.c
./test/dsets.c
	The number of slots in the raw data cache can be queried or
	set with H5Pget/set_cache(), which now take an extra argument.
	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%.

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

./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

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

./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

650e88756c [svn-r452] Changed tests to use the new dataspace API calls. Still need to add tests for
point selections and strides.

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

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

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

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

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

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

	Plugged a memory leak in the library termination code.

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

./src/H5.c
./src/H5private.h
./src/H5A.c
./src/H5AC.c
./src/H5D.c
./src/H5Ffamily.c
./src/H5Fistore.c
./src/H5G.c
./src/H5Gprivate.h
./src/H5HG.c
./src/H5O.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().

15f2fb8184 [svn-r408] ./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.

d392756a1b [svn-r400] 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.
