----------------------
./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).
----------------------
./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/H5Osdspace.c
./src/H5Oshared.c [NEW]
./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]
./src/Makefile.in
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/H5HLprivate.h [renamed from H5Hprivate.h]
./src/H5HLpublic.h [renamed from H5Hpublic.h]
./src/H5Oefl.c
./src/Makefile.in
./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
----------------------
./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.
----------------------
./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.
----------------------
./MANIFEST
./configure.in
./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'.
----------------------
./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/H5Dprivate.h
./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/H5Osdspace.c
./src/H5Ostab.c
Fixed warnings reported by marek@iiasa.ac.at. Thanks Marek.
./src/H5Odtype.c
Fixed a failing assert() wrt reading compound types (not
present in hdf5-1.0.0a).
----------------------
./configure.in
./configure
./test/iopipe.c
Added check for system(3)
./config/freebsd2.2.1
./config/linux
Added -DH5D_DEBUG to the debug flags.
./src/H5D.c
./src/H5Dprivate.h
./src/H5P.c
./src/H5Ppublic.h
./src/H5Sprivate.h
./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.
----------------------
./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
./configure.in
./src/H5Fprivate.h
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.
----------------------
./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
Changed H5Dget_create_parms() to H5Dget_create_plist().
./src/H5D.c
./src/H5Farray.c
./src/H5Fprivate.h
./src/H5Oefl.c
./src/H5Oprivate.h
./src/H5Sprivate.h
./src/H5Ssimp.c
./test/external.c
./test/istore.c
External raw data file I/O for contiguous storage is now
working. The library supports segments of various sizes which
can be scattered throughout multiple files in any order.
./test/Makefile.in
Remove more temporary 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/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.
----------------------
./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.
----------------------
./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
----------------------
./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.
----------------------
./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().
----------------------
./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.
----------------------
./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.,
Irix64) and are able to generate >2GB files on Irix XFS file

./src/H5E.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

./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.
When configure with enable-paralle, H5detect and debug were not
compiled with $(LIBS) but were executed via RUNTEST (mpirun ...).
The O2K mpirun can't handle such an object code.
Solutions:
Compile them also with $(LIBS) which contains the mpi library names.
Could have just removed $(RUNTEST) but in some parallel system, all
object file may have to be launched by some mpirun-equivalent command
anyway.
Platforms tested: O2K
Added modification entry to H5F_open header. Should have been done
when i added the access template argument.
H5Fprivate.h:
The hardcode setting to "define MPIO as the default IO
when HAVE_PARALLEL is set" cause all test programs to fail since
none of them is coded with the needed MPI_Initialize. Change it
back to the previous setting of using sequential I/O allows user
to use sequential I/O by default and use MPIO only if he/she explicitely
asks for it via access template setting.
file does not exist, the code tried to open the file with EXCL CREATE.
ROMIO cannot handle file-open with EXCL Create due to racing problem.
The first process creates the file which then fails all
other processes.
Solution: In the parallel code, turn on TRUNC mode to allow "late" open
calls to succeed too. It is safe to force TRUNC mode since the file is
known non-existing at that point. The MPIO implementation has to
provide the real solution.
Platform tested: O2K with ROMIO.
while he is visiting LLNL. I changed the default creation template
offset and length to 4. Will fix the problem later.

Fixed a few irix64 warnings regarding size_t vs. int,
variables set but not used, printf formats
./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.
not assign the decoded value back to n.
Solution: Removed temporary variable _n (don't see why it is needed.)
Use the variable n directly.
Platform tested: IRIX64 -64
----------------------
./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.
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'.

./src/H5D.c
./src/H5Dpublic.h
Added H5Dget_create_parms(), trying to stay one step ahead of
Elena ;-)
----------------------
./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.
