Update
Description:
Added a "metadata flush" function which allows the clients to force a
dump of the metadata from the SAP. This should be done before closing
the file.
Modified the information stored on an "open" of the file. The
filename is unnecessary, so I got rid of it.
More integration with the File Driver code: Passing in a data xfer
property list.
Platforms tested:
Linux

Update
Description:
Removed some obsolete fields - such as the AC_subst_t object ID -
which isn't needed. Fixed so that there are fewer global variables.
There are still some left, however. Modified the client and server
code so that it handles read requests better. There were some flaws
in how this was done before (it was calling H5FD_read() instead of
just returning the status that it couldn't find the metadata in the
cache).

Update
Description:
H5FP.c, H5FPclient.c, H5FPprivate.h, H5FPserver.c:
Update. More progression towards the SAP as metadata cache. It
only lacks the ability to take care of metadata allocations.
H5FDfphdf5.[ch]:
Start of a new driver for FPHDF5. Not fully implemented just
yet...

Update
Description:
Changes:
- Added support for the server dumping metadata writes to a
client.
- Some of the code wasn't handling allocated buffers correctly
(freeing twice).
- Modified server so that it handles metadata only.
Platforms tested:
Linux

Update
Description:
This is the first conversion of the FPHDF5 code to be a metadata
cache. There's an extra error message. I rewrote the sync/change code
to be read metadata/write metadata instead.
I still need to hook these changes into the HDF5 code so that it
looks at the SAP first before checking the file for metadata.

Code cleanup/new feature.
Description:
Split FUNC_LEAVE into API and non-API specific versions. This allows a
solution to compiling this branch with C++, as well as reducing the size
of the binaries produced.
Platforms tested:
FreeBSD 4.7 (sleipnir) w/serial, parallel (including MPE) & thread-safe

Update
Description:
A few generic changes to the FPHDF5 code. Some error messages
reworked a bit. Cleaning up in case of failure improved in some
cases. Added another field to the synchronization messages...

FPHDF5 Fixups
Description:
- Stopped using API calls in the H5FPclient code. It now uses
internal library calls.
- Removed some FIXME comments because they've been fixed.
- Small fix for an enum starting at 37 for no reason :-)
Platforms tested:
Eirene (only affects FPHDF5, so no need to test 3 platforms just yet).

Update
Description:
Added code which performs an update when there's a dataset creation.
Commented on some FIXMEs which were in the code.
Platforms tested:
Eirene PP
Arabica Fortran
Modi4 PP Fortran

New Feature. Support for new FPHDF5 Feature
Description:
More support for the FPHDF5 feature. This splits the H5D_create
function into separate parts which update the metadata cache. It was
necessary to split apart the H5O_create function to do a similar
thing since it would allocate real space on the hard disk.
I'm checking this up now so that I don't get too far away from what
the CVS repository has and so that others may look at the code and
retch^H^H^H^H^Hmarvel at it. If there are any comments, send them my
way.
There is one outstanding issue, though. I need to use non-API
functions in the FPHDF5 stuff. I'm using some APIs right now and
should migrate to using others. At the moment, I'm putting that on
the back burner until I'm more along in the implementation.
Platforms tested:
Arabica (C++)
Eirene (Parallel)
Modi4 (Parallel)

Code cleanup
Description:
Add more comments and clean up small bits of the FPH5 code.
Platforms tested:
FreeBSD 4.7 (sleipnir), changes too minor to affect other platforms.

Oops
Description:
The H5FPprivate.h file was being #included even if PARALLEL was
turned off.
Solution:
put the #include of the H5FPprivate.h file within the #ifdef block so
that it doesn't get included if H5_HAVE_FPHDF5 isn't defined.
Platforms tested:
Linux...

Feature Add
Description:
New files for the Flexible Parallel HDF5 stuff.
H5FP.c - Module housing the APIs to FPHDF5
H5FPclient.c - Module housing the internal client APIs
H5FPserver.c - Module housing the internal server APIs
H5FPpublic.h - Header for public APIs
H5FPprivate.h - Header for private APIs
H5Ofphdf5.c - Way of serializing FPHDF5 information to and from the
SAP
H5Oplist.c - Way of serializing a generic property list.
Solution:
[details about the changes, algorithm, etc...]
[Please as detail as you can since your own explanation is
better than others guessing it from the code.]
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}?
[If no, why not?]
Other platforms/configurations tested?
Misc. update:
Update MANIFEST if you add or remove any file.
Update release_docs/RELEASE for bug fixes, new features, etc.
Update applicable document files too.
