Bug fix
Description:
Fixed bug in hyperslab iteration where certain combinations of flattened
and non-flattened dimensions would cause incorrect locations to be iterated
over.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor to require h5committest
Code cleanup
Description:
Note in the release notes that the short MPI-I/O bug has been fixed and
also clean up the configure.in a bit.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor to require h5committest
Bug fix
Description:
Attributes which were created with scalar dataspaces were reporting their
dataspace as a simple dataspace when queried later.
Solution:
Fix the dataspace handling code when reading in the attribute message from
the file to set the extent type correctly.

Bug fix.
Description:
Using a selection offset with hyperslab selections in chunked datasets
was getting into an infinite loop and hanging the application.
Solution:
Apply the selection offset to the hyperslab selection properly.
Platforms tested:
FreeBSD 4.9 (sleipnir) w & w/o parallel

Bug fix
Description:
Make a copy of the index value for H5Giterate and use that instead of
dereferencing the index pointer.

directory. This eliminates the problem that the builder may not
have permission to install in the default install directory.
It also allows multiple builds in the same host or multiple srcdir
using the same source.
Platforms tested:
Eirene plus eyeballing of changes.
Misc. update:
Bug fix
Description:
Variable length strings and sequences with NULL pointers were not handled
by library, causing problems access the data. This also affected fill values
for variable-length datatypes.
Solution:
Address the issues in the library by detecting NULL sequences/strings
and avoid trying to convert them.
Patched up dumper to display NULL sequences/strings.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Code optimization
Description:
Improved integer & floating-point datatype conversions by removing some
corner cases. Got rid of algorithm which walked the buffer of elements to
convert backwards, switching to algorithm which computes the non-overlapping
space in the buffer and repeatedly converts it in the forward direction.
Platforms tested:
FreeBSD 4.9 (sleipnir)

Cray SV1 & T3E (T90 is not accessible)
Bug fix & code cleanups
Description:
Change our use of MPI derived datatypes to not create datatypes with
"0-sized" lengths, which causes the LANL Q machine to hang.
Also, get rid of "prefer MPI derived datatypes" environment variable since
it has no advantage.
Platforms tested:

Bug fix
Description:
Single hyperslab selections (which were set with only one call to
H5Sselect_hyperslab) that had dimensions that could be "flattened" but were
interspersed with dimensions that could not be flattened were not correctly
handled, causing core dumps.
Solution:
Re-work "flattening" code to handle this case properly.

Misc. update:
Purpose: Maintenance
Description: Added instructions for how to configure the Libraries not
to use external filters gzip and szip (gave a reference
to the proper section of the INSTALL_WINDOWS.txt file).
Fixed few typos; added pointer to the HDF FTP directory
where precompiled zlib and szlib can be found.

Misc. update:
Purpose: Maintenance for the 1.6.1 release
Description: Updated "platforms tested" section using the reports
sent out for the hdf5-1.6.1-pre1 testing; added
h5pget_driver_f subroutine to the "Known problems" section.

Misc. update:
document a known windows bug for dumper.
Description:
Two tests: h5dump --xml thlink.h5 and h5dump --xml tmany.h5 failed on windows
xp on .Net for debug and debug dll.
Solution:
Not worth to spend more time on this, just document this.

Solution: N/A
Platforms tested: done with bin/h5vers on eirene
Misc. update:
Purpose: Bug fix
Description: Type of the third argument to the h5pset(get)_cache_f subroutines
was incorrect (INTEGER instead of INTEGER(SIZE_T)).
I was confused while doing my previous change since
fortran docs were wrong, and the type of the same argument in
1_4 branch is INTEGER. I forgot to check carefully #if def for
1_4 branch in the C code, and encountered only int type for the
corresponding C functions. Since Fortran doesn't support
backward compatibility, type of the argument should be
always in sync with the latest branch.
Solution: ALWAYS, ALWAYS pay attention to compiler's warning.
Fixed type to be INTEGER(SIZE_T).
Platforms tested: kelgia, copper 64-bit mode, solaris 2.7 64-bit mode.
Misc. update:
Purpose: Bug fix
Description: Parameter rdcc_nelmts of the h5pget_cache_f subroutine
had wrong INTEGER(SIZE_T) instead of INTEGER type.
Solution: Fixed the type
Platforms tested: arabica in 64-bit mode (where INTEGER(SIZE_T) is not
the same as INTEGER)
Misc. update:
Bug fix
Description:
The 'char *' type is one of the "strongly" aligned types on Crays, but
a 'void *' is "weakly" aligned. So, assigning a 'void *' (pointing to a
location to place a 'char *') to a 'char **' can change the pointer value
during the assignment.
Solution:
Don't alias the 'void *' where the variable-length information ('char *'
or 'hvl_t') will go. Use a temporary variable on the stack to build up the
information about the VL string or sequence and then memcpy() the temporary
variable directly to the location pointed to with the 'void *'
Platforms tested:
FreeBSD 4.9 (sleipnir)
Cray SV1 (wind)
specific to Cray problems, h5committest not necessary.
Bug fix
Description:
When too many messages were inserted into an object header, the library
had an internal pointer to the "new message" that was pointing to the incorrect
location when the array of messages was re-allocated.
In the worst case, this could cause a file to be corrupted.
Solution:
Update the internal pointer when the array is re-allocated.
