----------------------
./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.
----------------------
./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.

./src/H5G.c
./src/H5O.c
./src/H5Osdspace.c

./test/big.c
./test/cmpd_dset.c
./test/dsets.c
./test/extend.c

Now that I have a home-grown version of Purify I fixed all the
leaks in all the test files.

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.
----------------------
./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/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.
----------------------
./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.

We now detect and use fseek64() on systems that have it (e.g.,

systems (and anything else that supports large files). This
change also removed some warning messages from the Iris `-64'
compiler.

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.
while he is visiting LLNL. I changed the default creation template
offset and length to 4. Will fix the problem later.
