Bug Fix
Description:
If a non-zero fill-value is used for a chunked dataset, any non-existent
chunked read with an "all" selection (or a contiguous hyperslab selection)
will return zero for those instead of the user's fill-value.
Solution:
Fixed I/O code to pass down fill-value to "optimized" I/O routines, so it
will be available to fill the user's buffer with.
Platforms tested:
FreeBSD 4.5 (sleipnir)

Code speedup
Description:
Chunking I/O routines are reading in an entire chunk when performing I/O
on the chunk, even if the chunk will be too large to cache.
Solution:
If the chunk is too large to cache, uncompressed and has been allocated
space in the file, or if we are using the MPI-I/O VFD, perform the I/O
directly to the chunk, instead of reading the chunk into memory, updating
it and immediately writing the entire chunk back out.
Platforms tested:
FreeBSD 4.5 (sleipnir) (using serial access) and IRIX64 6.5 (modi4) (using
parallel access with MPI-I/O)

Bug Fix
Description:
When file space was returned to the file space free-list for reuse,
occasionally raw data allocations which used space from the free-list
would overlap with the metadata accumulator and get over-written with
the cached information in the accumulator, corrupting the data.
Solution:
Check if the space about to be recycled on the free-list is going to be
used for raw data and also overlaps with the metadata accumulator cache,
avoiding using space that fits those criteria.
This fixes bug #701

Bug Fix.
Description:
The H5Rget_object_type function could not get the object type for dataset
region references.
Solution:
Added a new function, H5Rget_obj_type, to replace H5Rget_object_type.
The new function requires the reference type as an additional parameter,
in order to allow queries on different reference types to be performed
correctly.

Bug Fix
Description:
The file metadata macros generate unaligned access warnings on the IA64
architecture.
Solution:
Got rid of bogus big-endian vs. little-endian differentiation when encoding
and decoding file metadata and use proper set of macros to prevent unaligned
access problems.
This fixes bug #672.

Bug Fix
Description:
The code in H5Sselect_hyperslab_valid contained an fencepost error and is
allowing selections which overlap the extent by exactly one element in any
dimension to pass as valid instead of flagging the selection as invalid.
This bug only affects hyperslabs which have been OR'ed together, not the
selection from a single H5Sselect_hyperslab.
This fixes bug #550.
Solution:
Changed an '>' to an '>=' and added new regression test to check for error.

Code cleanup
Description:
Property that H5P(g|s)et_hyper_cache uses is no longer in use inside the
library.
Solution:
Removed H5P(g|s)et_hyper_cache API functions, except when backward
compatibility is turned on. When backward compatibility is turned on,
the property is defined by the library, but unused internally.

Document bug fix.
Description:
The internal B-tree code was dumping core with an assertion failure when
flushing data to the file if too many objects were put into the same B-tree
(forcing the root node to split, I think).
Solution:
Fixed the B-tree copy routine to copy the correct number of raw keys.

Kludge
Description:
Since we're only about halfway through converting the internal use of
property lists from the "old way" to the generic property lists, we turned
off snapshots to avoid exposing lots of API changes to users, until the
APIs settled down.
Getting the snapshots rolling again seems to have become a priority, so
some changes are going to have to be made now that were going to be
postponed until we were completely finished with the conversion. This
requires that the old API functions be able to deal with both the old
and new property lists smoothly.
Solution:
Kludge together the property list code so that they can transparently handle
dealing with both the old and new property lists
