Bug Fix & Update
Description:
FPHDF5 was creating files which didn't have the EOA field in the
superblock set correctly. It turns out that the SAP was keeping this
information to itself instead of giving it to the client processes.
Naughty SAP!
Solution:
Have the SAP send this information back to the clients so that they
can update the superblock as necessary. This now creates a file (with
just the root group) that looks correct! Only problem is that there's
extra file space being allocated. Also, at program termination,
there's an infinite loop...
Platforms tested:
H5committests (run by hand on burrwhite, arabica, and modi4)

Bug fix and Update
Description:
From Quincey's comments on the code I checked in last night:
- In H5F_close call, the "private" processes should call the
H5F_flush with the "CLEAR_ONLY" flag.
- There's no need for a special case for FPHDF5 in the
FD_real_alloc function since FPHDF5 doesn't define an alloc
function.
- The return type of H5Pset_fapl_fphdf5 should be herr_t instead
of hid_t. I don't know how it got that way in the first place.
- The variable names for MPI types and the structure typedefs
should be switched: H5FP_request/H5FP_request_t to
H5FP_request_t/H5FP_request and so on.
- In the H5FP.c module, I was commiting the H5FP_request MPI
datatype but using the wrong offset field...
Platforms tested:
Linux...will test on others, but these are mostly FPHDF5 changes.

Update
Description:
More changes to the FPHDF5 file driver. Too many to mention here.
Some highlights:
- Addition of lock/unlock methods to the driver, though they
aren't implemented fully just yet.
- Extra query functions to determine various things about the
file. (If this is the captain process, etc)
- Fixes to make things work...

Bug Fix
Description:
Private header file was included in a public header file by mistake.
Solution:
Put the private header file into the .c module instead.
Platforms tested:
Linux 2.4 (see, I really did test it).

Update
Description:
Since metadata doesn't use a "set view" to do I/O, I moved the check
for the use_set_view variable down into the "real" write routine.
Also added a check for when the server is dumping metadata to the
file. in that case, don't write this information to the SAP...

Update
Description:
Added the flush function.
Modified so that it calls the FPHDF5 code for reading and writing.
This involved splitting the write function up into three different
parts to avoid lame goto's. There's some code which will copy a data
xfer property list and add in there that we're "dumping" the data so
that we can recall this layer when the SAP dumps metadata to a
process...

Update
Description:
Folded in Quincey's changes to the caching stuff. (Stole the code
from the H5FDmpio driver).
Roughed in some code for doing a read from the SAP. Also roughed in
code for doing a write. However, the write requires an OID, which I'm
not sure how to pass down into the driver (maybe via the
dxpl_id?...but then it has always to be set before calling one of
these routines...).
Removed some of the global variables which were there because of the
FPHDF5 stuff...
Removed the H5Ofphdf5.* stuff from the Makefile.in, since I'm pretty
sure it's going away and I don't want to waste time updating that
module if that's the case...so just don't compile it.

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...
