Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".

the minimum set of header files that should be installed
Solution: Fixed

Misc. update:
Update.
Description:
Update HDF5 Windows installation documentation to include recently added HDF5 high level library and tests information.
Solution:
Platforms tested:
Not necessary.
Misc. update:
Bug fix
Description:
Correct values used in "space utilization" equation: the 'used' and
'total' values were backwards.
Platforms tested:
FreeBSD 4.10 (sleipnir)
Too minor to require h5committest
Bug fix
Description:
Fix core dump when flushing a file with a newly created attribute which
hasn't had a value written to it still open.
Solution:
Write the attribute fill value when appropriate.
Platforms tested:
FreeBSd 4.10 (sleipnir)
Linux 2.4 (verbena)
Solaris 2.7 (arabica)
Purpose: change feature
Description: Back up support bitfield and time datatypes in H5Tget_native_type.Leave it to future support. Let it return "not supported" error message for
now.
Platforms tested: h5committest and fuss.
Misc. update: RELEASE.txt
Bug fix
Description:
Relax restrictions on parallel I/O to allow compressed, chunked datasets
to be read in parallel (collective access will be degraded to independent
access, but will retrieve the information still).
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Solaris 2.7 (arabica)
IRIX64 6.5 (modi4)
h5committest
Description: enable size adjustment for compound datatype. The size
can be increased and decreased(as long as the last member isn't cut).
Solution: mainly check if the last member is being cut when decreasing
the size. Others are simply taking out assertion to enable this feature.
Platforms tested: h5committest and fuss.
Misc. update: RELEASE.txt
Bug fix.
Description:
Fix off-by-one error in Core VFL driver which would cause spurious address
or size overflow errors when an odd valued address or size was checked.
Platforms tested:
FreeBSD 4.10 (sleipnir)
Linux 2.4 (heping)
Solaris 2.7 (arabica)
Update release_docs/RELEASE.txt to describe options for dealing
with installations which insert extra text in output, thereby
breaking tests which function by comparing output with an exemplar.
Description:
See above.
Solution:
Add discussion of this possible problem, and listed two possible
solutions:
1) "setenv HDF5_Make_Ignore yes" and then score "failed" tests
by hand.
2) Use the RUNSERIAL environment variable to use a filter script
to filter out the extra text.
Platforms tested:
No testing needed.
Misc. update:
Bug fix
Description:
Correct typedef for dataset region references to avoid struct alignment
issues on Crays.
Solution:
Change the typedef for hdset_reg_ref_t from a struct to an array of
unsigned char's of the correct size and propagate the appropriate adjustments
around the code.
Platforms tested:
FreeBSD 4.10 (sleipnir)
Linux 2.4 (verbena) w/fortran
Cray T90 (subzero) w/fortran
Cray SV1 (wind) w/fortran & parallel
Cray T3E (cyclone) w/fortran & parallel
Description: Restore 6 old error API functions back to the library to be backward
compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto,
H5Eget_auto. These functions do not have error stack as parameter.
Solution: Internally, these functions use default error stack.
Platforms tested: h5committest and fuss.
Misc. update: RELEASE.txt
Bug fix (sorta)
Description:
Change reading of "missing" chunks from datasets with undefined fill
values to not overwrite the application buffer with random garbage from
memory. Note that this is almost the same, since whatever garbage the
application had in those locations will still be there...
Platforms tested:
FreeBSD 4.10 (sleipnir)
IRIX64 6.5 (modi4)
h5committested
Description: Added PGI Fortran support for Linux64 systems (x86_64)
Solution:
Platforms tested: AMD Opteron box at AMD Sunnyvale and verbena
with PGI and gcc compilers.
Misc. update:
Bug fix
Description:
Correct possible core dump when a datatype conversion function is
registered with the library after a compound datatype has been converted
(having it's type conversion information cached by the library). The compound
datatype must have been created by inserting the fields in non-increasing
offset order to see the bug.
Solution:
Re-sort the fields in the compound datatypes before recalculating the
cached information when performing the conversion on them.
Platforms tested:
FreeBSD 4.10 (sleipnir)
h5committested
Bug fix
Description:
Correct buffer overrun in "multi" VFL driver that was writing past the
end of the "driver name" buffer when encoding the driver info block for the
file's superblock.
Platforms tested:
FreeBSD 4.10 (sleipnir)
Too minor to require h5committest
Bug fix.
Description:
Address two problems:
- The computation of the scanline in the szip filter was being
performed in the "can apply" callback routine instead of the
"set local" routine.
- The routine which allocated all the chunks for an entire dataset
(which is invoked when the allocation time is early or late,
rather than incremental) wasn't recording a failed filter in
the information for the chunk, causing the library to believe
that the chunk had the filter applied when it really hadn't.
Solution:
- Move the scanline computation to the "set local" callback.
- Record the filter mask with each chunk created when allocating them.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/szip
Too obscure to require h5committest
Description: Added support for Absoft Fortran compiler
Solution: Modified configuration file to check which Fortran compiler is used
and set appropriate flags.
Platforms tested: verbena with pgf90 and Absoft f95 compilers
Misc. update:
Bug fix
Description:
Allow I/O on extendible chunked datasets with (currently) zero-sized
dimensions to proceed harmlessly instead of dumping core on an assertion.
Solution:
Removed assertion and added checks to avoid problem situation in H5TB_end
Platforms tested:
FreeBSD 4.10 (sleipnir) w/ & w/o parallel
Too minor to require h5committest
Bug fix
Description:
Always write fill values to chunks when initializing entire B-tree and
any filters are defined.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel

Too minor to require h5committest
