feature
Description:
h5repack support for scaleoffset compression
Checking in early to help debug the filter.
Solution:
Added messages and command line to handle new scale offset filter.
Note: TESTS ARE DISABLED FOR NOW. The filter is not
complete, repack tests may fail due to know problems.
PLEASE DO NOT MESS WITH THE SCALEOFFSET TESTS AT THIS TIME.
They will be enabled when the filter is ready.
Platforms tested:
verbena,copper,shanti

MANIFEST
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".
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel & fphdf5
FreeBSD 4.10 (sleipnir) w/threadsafe
FreeBSD 4.10 (sleipnir) w/backward compatibility
Solaris 2.7 (arabica) w/"purify options"
Solaris 2.8 (sol) w/FORTRAN & C++
AIX 5.x (copper) w/parallel & FORTRAN

Misc. update:
Fix SZIP filter to dynmically detect encoder.
Description:
Solution:
See:
http://hdf.ncsa.uiuc.edu/RFC/SZIP/Szip_dynamic_12_Oct.pdf
Changes to h5repack tests, contingent on detecting SZIP encoder.
Note new program:
testh5repack_detect_szip
Checks fo rencoder, prints out "yes" or "no". Used by hrepack.sh
to detect encoder. Can also be used for windows tests. This is
only used as part of the tests.
Had to modify Makefile to build and clean this program.
h5repack test
Description:
modified a test file generation contents, for more easy debugging
(generated just one reference dataset and one region reference )
Solution:
Platforms tested:
linux
aix
solaris
Misc. update:
new test
Description:
added a test that generates and copies a file with a dataset with fill value
(this is to test the property list function H5Pequal)
Solution:
Platforms tested:
linux
solaris
aix
Misc. update:
h5diff and h5repack changes
Description:
h5diff
introduced the following four modes of output:
Normal mode: print the number of differences found and where they occured
Report mode: print the above plus the differences
Verbose mode: print the above plus a list of objects and warnings
Quiet mode: do not print output (h5diff always returns an exit code of 1 when differences are found)
h5repack
added an extra parameter for SZIP filter (coding method)
the new syntax is
-f SZIP=<pixels per block,coding>
(pixels per block is a even number in 2-32 and coding method is 'EC' or 'NN')
Example of use:
./h5repack -i file1 -o file2 -f SZIP=8,NN -v
updated usage messages, test scripts and files accordingly
Solution:
Platforms tested:
linux
AIX
solaris
Misc. update:
h5repack changes
Description:
there were some requests to change some minor h5repack features
h5repack only made a warning about a non available filter in verbose mode ( -v )
without -v it kept silent, and users sometimes missed this warning
the request was that it should print this warning always. so, the new format, is e.g
./h5repack -i test_szip.h5 -o out.h5
Warning: dataset </dset_szip> cannot be read, SZIP filter is not available
due to this, and to avoid a lot of these messages in the shell test script, I modified
the script h5repack.sh so that it detects the presence of all filters in the environment
(previously it only detected SZIP)
the test files were also divided in more files , to make the script code easier to
follow
Solution:
Platforms tested:
linux
AIX (no szip)
solaris (no szip, no gzip )
Misc. update:
Code cleanup
Description:
Clean up lots of warnings based on those reported from the SGI compilers
as well as gcc.
Platforms tested:
SGI O3900, IRIX64 6.5 (Cheryl's SGI machine)
FreeBSD 4.9 (sleipnir) w/ & w/o parallel
h5committest
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:
new tests for h5repack
Description:
added more tests both to the test program and shell script that test
a variation of different filter converssions
Solution:
Platforms tested:
linux
Misc. update:
new tests for h5repack
Description:
added tests that do layout type to layout type conversion in a matrix of 9 between compact, contiguous and chunking
Solution:
Platforms tested:
linux
afs has problems; I could not telnet to sol and copper, arabica is really slow (meaning
waiting 1 minute for a typed character) and the writing of a file gave an error
arabica 181% afs: failed to store file (145)
afs: failed to store file (145)
Misc. update:
bug fix in H5Zshuffle.c
add more tests to h5repack that exposed the bug
Description:
when creating a dataset with the shuffle filter and duplicating it in a new dataset (file)
the call to H5Z_set_local_shuffle failed. this is because the value of cd_nelmts of the filter
structure is set to 1 (H5Z_SHUFFLE_TOTAL_NPARMS) when the original dataset is created, but when
the new dataset is created there is a checking instruction that fails if the value of
cd_nelmts is not 0 (its original value, H5Z_SHUFFLE_USER_NPARMS)
Solution:
just remove that check condition, since the value of cd_nelmts is not used anyway.
if we decide that the value of cd_nelmts is necessary, then the H5O_pline_copy function
must be changed to update this value (a different update for each filter)
Platforms tested:
linux
solaris
AIX
Misc. update:
added h5repack and h5diff support for copying and differences of references to dataset regions
modified the behaviour in the diff of attributes, when a difference in name is detected
in the attribute cycle (number of attributes of object), instead of exiting the
cycle, rather continue
