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.
Solution:
Fix them
Platforms tested:
windows xp
Misc. update:
Code optimization
Description:
Avoid clearing the error stack unless necessary.

Solaris 2.7 (arabica)
FreeBSD 4.9 (sleipnir)

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.
Platforms tested:
h5committested
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().

Code cleanup
Description:
Clean up lots of warnings based on those reported from the SGI compilers
as well as gcc.

Misc. update:
Code optimization
Description:
Instead of re-initializing the default stride & block arrays to have values
of '1' in each position each time we perform a hyperslab selection, create
static constant arrays with '1's in them.
Platforms tested:
Solaris 2.7 (arabica)

Code optimization
Description:
Don't copy hyperslab span information as much.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.9 (sleipnir)
too minor to require h5committest
Bug fix.
Description:
Not all machines (like Sun and AIX) support fabsl() and fabsf() used
in test/dtypes.c. Changed the coding to use macro names HDfabsl and
HDfabsf. Also set the two macros to use ABS for now so that they will
work for all machines. (need more portable fixes which would involve
configure.)
Platforms tested:
h5committested. (also tested in LANL QSC and Theta).
Code optimization
Description:
Compute value for array instead of using memset(), since we are looping
through the array indices anyway.

bug fix.
Description:
On LANL QSC, test/dtypes "sw long double -> double" had failed when the
long double values were too small, smaller than the minimum double normalized
floating number. The hw in QSC converts them mostly to 0 but occasionally,
it converts to the some non-zero values which are still <= the minimum
double normalized number. But the conversion verification did not like
them and flagged them as errors.
Solution:
Added code to check if the src value is already smaller than the minimum
number the float class can hold. When that happens and if both hw and sw
conversion results are <= the minimum number, then accepts them as okay
because if the src is smaller than the dst minimum number, an underflow
has occured.
Platforms tested:
Tested in LANL QSC and Theta.
feature
Description:
H5check_version will print warning messages if the version does not
match or if the lib version string is not consistent, even when
$HDF5_DISABLE_VERSION_CHECK is set to 1. This will mess up
tests that try to match output.
Changed it so that if $HDF5_DISABLE_VERSION_CHECK is set to 2, no
warning about version mismatch is printed.
The lib version string warning is suppressed if $HDF5_DISABLE_VERSION_CHECK
is set to any non-zero value.
Platforms tested:
Tested in sol only but pretty comprehensive to make the warnings do get
suppressed.

Description: This test script put executable program in hdf5/test/testfiles where

Bug fix.
Description:
Temporary output files were created in the source directory.
If multiple build/tests using the same source directory occur
at the same time, they would conflict because of the same file
names.
Solution:
Changed it to create temporary output file in the current build
directory.

around.

new test
Description:
add a test that generates a file with "holes" and then uses h5repack to clean
the empty space. it works
Solution:
Platforms tested:
linux
Misc. update:
Description: Mainly are header message changes for dataspace. In last round
of check-in, a new header message for dataspace to created, which is not a good
way. Now, there will be no new message for dataspace, but just add the type of
dataspace in the message while increment its version number. Backward compatibility
is addressed. The attribute design is modified accordingly. Took out Null
dataspace test from tmisc.c and put it in th5s.c. These files are re-generated
since the header message has been changed.
