New feature
Description:
Previously we have two windows .zip files for hdf5. One for c/c++ and
one for fortran. That added double maintenance work and also bug-driven.
Solution:
Use one merged all.zip.
By default, only C library will be tested.
Users can check fortran and c++ project files for fortran tests.
Detailed project list to be checked will be provided in windows doc.
Platforms tested:
windows xp 6.0 VS C++, Dec Fortran
windows 2000 6.0 VS C++, Dec Fortran, Intel C++
Misc. update:

locate information about a chunk on disk.

routines.

Slight improvement.
Description:
Show directory name at the beginning and ending of running
make check in a directory. Together with the time stamp,
it will be easier to see how much time it takes to run all
the tests in one directory.
Platforms tested:
Eirene only.
Misc. update:
Bug fix (sorta)
Description:
Add hack to allow the MS Visual Studio 6 compiler to build the library.
It cannot cast unsigned long long values to float or double values. So, add
another configuration macro to disable this conversion in the library. Just
the "hardware" conversion is disabled, so the library will still correctly
convert unsigned long long to float and double values, it will just happen
more slowly with the "software" conversion routine.
Platforms tested:
FreeBSD 4.9 (sleipnir) with "Windows" setting faked
inappropriate for h5committest
Description: H5Pset_type_conv_cb and H5Pget_type_conv_cb weren't put into
H5MPprivate.h. Another thing is the func type doesn't match the func field
in the struct in these functions.
Platforms tested: RH 8(fuss) and sleipnir
Bug fix (sorta)
Description:
The SGI machines have problems accurately (and consistently) converting
unsigned long values to float and double values, so put in a bit of a hack in
the datatype conversion test code to allow them to get "close enough". This
hack is enabled at configure time by a flag which should only be set on machines
with this problem.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Description: A new exception handler for datatype conversion(set through
H5Pset_type_conv_cb) to replace the old overflow callback function(set
through H5Tset_overflow). This new handler can deal with overflow, precision
loss and fraction truncate during datatype conversion.
Platforms tested: h5committest

Undo the mysterous changes.
Description:
Somehow something changed this file during snapshot release.
Undo the change.
Platforms tested:
No test since it is a simple editing.
Misc. update:
bug fix
Description:
szip dll path was wrong at debug version
Since h5dump --xml thlink.h5 and h5dump --xml tmany.h5 failed for debugging due to
string allocation violation in h5dump.c; we turned off these two tests
for debug testing.
Solution:
Add a temporary batch file called dumptstdebug.bat for the time being.
Platforms tested:
windows 2000 VS 6.0.
Misc. update:
bug fix
Description:
h5repack and h5repacktst are not included in all dependencies.
unresolved externals in h5repack and h5repacktst.
Solution:
Added all dependencies on h5repack and h5repacktst.
Added h5repack and h5repacktst dependencies on toolslib.
h5repack and h5repacktst settings/Link/Object/library modules: added zlib.lib szib.lib.
Platforms tested:
Windows XP MS VS 6.0
Misc. update:
Code optimization
Description:
Instead of dynamicly allocating various arrays for various pieces of
information about a selection or selection iterator, just use fixed size
array of size H5S_MAX_RANK (as the rest of the library does).
Platforms tested:

h5comittest
Purpose: Maintenance
Description: h5dwrite/read_f and h5awrite_read_f functions were overloaded
with dims argument being of type INTEGER and INTEGER(HSIZE_T).
We promised to remove overloading in 1.4 release. It was
removed from documentation but not from the source code.
Solution: Finish code cleanup.
Platforms tested: Solaris 2.7 32 and 64 bit, and copper with --enable-
parallel. Windows are broken, so Kent and Xuan
will test it with their changes later.
Misc. update:
Windows update including project update, H5Tinit.c update.
Description:
H5detect.c has been changed in UNIX, H5Tinit.c needs to be updated.
Several test files have been re-arranged.

Bug fix.
Description:
The data verification code didn't work. Also numerous minor bugs.
Solution:
Re-wrote data write and verification code. In particular, I
modified the verification code so it actually verifies data.
In the future, this test should be modified so it exercises
object deletes and chunk I/O.

Checkpoint checkin of FP bug fixes. FP is still quite
buggy, but I must go deal with other matters.
Description:
Fixed two major bugs:
1) H5FPserver.c was clobbering meta data in its care.
2) H5FPserver.c was allocating the same space multiple
times, causing both data and meta data corruption.
Also made minor fixes, added debugging code, and familiarized
myself with the FP code.
All development work with FP enabled was done on Eirene.
On this platform, FP now passes its test reliably with
up to 9 processes. At 10 processes it seg faults every
time. I haven't looked into this issue.
There are also several known locking bugs which have to
be fixed. However, they are of sufficiently low probability
that I didn't bother with them on this pass.
FP has not been tested with deletions -- this should be
done.
Also, need to test FP chunked I/O.
Solution:
1) Modified cache in H5FPserver.c to merge changes correctly.
Found and fixed a bug in H5TB.c in passing.
2) Multiple space allocation was caused by a race condition
with set eoa requests.
Most of these eoa requests appeared to be superfluous, so
I deleted them.
Those issued during the superblock read seemed necessary,
so I inserted a barrier at the end of the superblock read,
to prevent races with allocations.
Platforms tested:
h5committested
Description:
Fixed bug in H5TB_less(). It was returning the next largest node,
instead of the next smallest as advertised.
Added comments warning that H5TB_rem()s will occasionally delete a
node other than the one provided in its argument list.
Solution:
It was sufficient t invert two comparisons in H5TB_less().
