option --enable-direct-vfd/--disable-direct-vfd to enable/disable Direct I/O support. The default
is enabled. There's a small test in test/vfd.c. Another way to test it is to set environment
variable HDF5_DRIVER to "direct" and run "make check" in the test/ directory. There'll be some
further improvement in the following checkin including allowing user to provide memory boundary
value, file block size, and copying buffer size.
Tweak down some of the static array definitions for new & re-loaded object
header data structures, to reduce memory use in common cases.
Tested on:
Linux/32 2.6 (chicago)
Add "use the latest format" support for dataspace object header encode/
decode routines and clean up format a bit for the latest format (new to 1.8.x
releases)
Remove storing 'perm' parameter for array datatypes in memory and the file,
and add test to make certain that if any user applications are attempting to
store them, we get some reports back. (Should be unlikely, since the RefMan
says that the parameter is not implemented and is unsupported).
Carry those changes into the tests, etc.
Clean up a bunch more compiler warnings.
Tested on:
FreeBSD/32 4.11 (sleipnir) w/threadsafe
Linux/32 2.4 (heping) w/FORTRAN & C++

to protect of previous root direct block, when converting heap to use a root
indirect block.

2. Using H5Dmpio_Debug macro to reflect the debugging information of new parallel IO supports.
They are very minor changes. Tested at heping. t_pflush2 failed. Others passed.
Bug Fix (Bug 544)
Description:
SGI Altix's MPI_File_get_size overflowed at 2GB and more.
Put in a temporary patch to use stat() instead to make Cobalt
passing on this test (bigdset). A better fix (like detect if
MPI_File_get_size does not work before using this is preferred.)
Tested:
Cobalt and Heping.
exposed by that one in which closing a read/write file ID wouldn't flush the
cache if there was another file handle open. This caused problems when the
second file handle was read-only; neither would actually flush the cache.
Now all read/write file handles flush the cache when the close, but only
when the file is going to be destroyed is the cache destroyed. This way
read-only file handles keep the cache open but it is always clean.
Tested on mir, heping, sol, and copper (parallel)
Description: Add a new part to the flush test that checks to see what happens in case a file is flushed, and
then a new dataset is created and the program exits without flushing this subsequent dataset.
The test verifies that, at the very least, the data written out before the H5Fflush call is correct.
Description:
It seems that, on AIX, calling MPI_Finalize without closing all files results in an error.
This causes t_pflush1 to fail because the whole point of the test is to see what happens if you
don't close a file. Try getting rid of the call to MPI_Finalize to see if this will silence the error.
Tested:
AIX (copper)
and quote its arguments. Also checks for the 'socket' library on
Solaris.
If this patch passes the Daily Tests and makes the user happy, I'll
port it back to the 1.6 branch.
Tested on mir and sol.
Finish 'use the latest version of the format' changes to the datatype
object header message. Compound and enumerated types will now be encoded
more efficiently by packing the field names & member offsets better.
Tested on:
Linux 2.6/32 (chicago)
Linux 2.6/64 (chicago2)
Add the "use the latest version of the format" support to datatype
messages. And a regression test to check that it's working.
Also, found that we have been over-allocating space for compound datatype
messages (when they have array datatypes or can use the latest version of the
format) and trimmed the size back.
Clean up datatype & dataspace encode/decode routines by having them
allocate & release "fake" file structures, which gets them out of needing to
"know" about the internals of file structures.
Other minor whitespace/formatting cleanups, etc.
Tested on:
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
Further minor modifications to the file format for tracking links in groups.
This is tentatively the "final" file format for groups.

Fix file handle destroy routine to not attempt to flush out partially
initialized file handles (when opening a file fails).

Moved definition of int64_t from H5private.h to H5public.h as a temporary
solution.
Tested on heping and Windows (windows also needed H5Gdense.c and H5Gbtree2.c
to be added to hdf5 project).
Add test to fractal heaps to exercise issues with opening the same heap
through two different file handles.
Fix issues with file handle contexts in metadata cache callbacks for heap
components.
Fix bug in file close handling where cached information was being
invalidated even when another file handle was open to the file.

File format is not stable, don't keep files produced!
Description:
First stage of checkins modifying the format of groups to support creation
order. Implement "dense" storage for links in groups.
Try to clarify some of the symbols for the H5L API.
Add the H5Pset_latest_format() flag for FAPLs, to choose to use the newest
file format options (including "dense" link storage in groups)
Add the H5Pset_track_creation_order() flag for GCPLs, to enable creation
order tracking in groups (although no index on creation order yet).
Remove --enable-group-revision configure flag, as file format issues are
now handled in a backwardly/forwardly compatible way.
Clean up lots of compiler warnings and other minor formatting issues.
