new feature
Description:
when requesting a filter for all datasets and the filter cannot be applied for one dataset
use the original dcpl withou filter and print a warning
this check was done previously with buit in functions for szip that are now in the library
Solution:
Platforms tested:
linux
solaris
aix
Misc. update:
bug fix
Description:
Description:
one case was not handled in the combination of input options (layout and filters)
Solution:
redo the algorythm that handles all cases
Solution:
Platforms tested:
linux
Misc. update:
bug fix
Description:
when specifying both an input object e.g -f mydset:GZIP=1 and a defined chunk -l CHUNK=20x20
the filter used a defined default chunk instead
Solution:
add a check for the input chunk
Platforms tested:
linux (small change)
Misc. update:
Refactor code
Description:
Refactor common code for determining the native type for using in the
tools into separate routine.
Also, reduce diffs between the two branches and bring back some fixes from
the development branch to the release branch.
Platforms tested:
FreeBSD 4.10 (sleipnir)
too minor to require h5committest
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
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 )
Solution:
Platforms tested:
linux
solaris
AIX
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++)
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
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
Solution:
Platforms tested:
linux
AIX
solaris
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
Solution:
Platforms tested:
linux

AIX
Misc. update:
new library function H5Pdelete_filter
deletes one or all filters from a dataset creation property list
this was done for the NONE option of h5repack, added tests for this feature
added a test for the new function in /test/dsets.c
Description:
Solution:
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

h5repack change
Description:
changed the default size of chunks when defining a new dataset to apply a filter

value, and it was causing write calls to fail on some files (probably a bug)
