new feature
Description:
added a check that the chunk size must be smaller than pixels per block in SZIP request
prints a message and exits, if not met

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

Misc. update:
bug fix, new feature
Description:
fixed bug in the parse function:
cases where we have an already inserted name but there is a new name also
example:
-f dset1:GZIP=1 -l dset1,dset2:CHUNK=20x20
dset1 is already inserted, but dset2 must also be (it was not)
added a CHECK_SZIP symbol to enable/disable checking of library related szip parameters
added the print of the filter name in verbose mode (confirms visually that the filter was applied )

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:
Purpose:
HDF5 now supports SZIP with no encoder.
Description:
SZIP can be configured to have both encoder and decoder or just to have the decoder. HDF5 can now query the configuration of any filter, and will throw errors if users try to write using a filter with encoding disabled.
Solution:
Added H5Zget_filter_info function, changed API for H5Pget_filter and H5P_get_filter_by_id. See SZIP RFC.
Platforms tested:
Copper (fortran, C++, parallel), Sleipnir (C++), Arabica (fortran, C++), Verbena (fortran, C++)

new tests for h5repack
Description:
added more tests both to the test program and shell script that test
a variation of different filter converssions

Misc. update:
bug fix
Description:
the synntax of the input of h5repack conatined double quotes and spaces, which
were causing problems on the parsing in AIX paralell
Solution:
replaced the spaces by =
that is, instead of -f "GZIP 6"
we have now
-f GZIP=6

Misc. update:
1) new function for tools library
2) new test script for h5repack
Description:
1) currently all the tools (h5dump, h5diff, etc) do not check if a filter is available
for reading some dataset that might have a filter not available on the current configuration (the behaviour
of the tools until now was to trigger a library error, saying that the dataset cannot be read
due to the lack of the filter)
Solution:
1) added a new function h5tools_canreadf that checks if a dataset can be read
depending on the availability of filters.
this function was added in calls for h5diff and h5repack.
instead of triggering the library error, a message is printed, saying that the dataset
cannot be read (the print is optional, it is on on verbose mode)
2) added a shell script that tests the commannd line tool behaviour of h5repack
the script does a series of runs of h5repack with several options on the same file (this file test4.h5
was added to the testfiles dir).
then, it runs the h5diff tool, with the input and output files , in each run.
the goal of the test is also to check item 1) . the binary file was saved with filters
that might not be available on other configurations
Platforms tested:
linux (all filters enabled)
linux (some filters disabled)
solaris (some filters disabled)
AIX (some filters disabled)
windows (all filters on and off )
Misc. update:
new feature, bug fix, changed function
Description:
1) implemented the option that says if the dataset is too small , do not compress it
2) bug fix in the SZIP checking . only apply szip to atomic datatypes
3) made the apply_filters function more compact

Misc. update:
h5repack new feature
Description:
in the SZIP settings, when the requested pixels per block parameter does not conform
to the SZIP specifications, instead of returning without applying the filter,
do an attempt to set this parameter to a valid value, issuing a warning in the process
