h5repack revision:
1. added a new test due to the introduction of H5Ocopy in the copy of objects (compressed dataset with references, that still must go a second sweep of the file to be regenerated).
2. Moved all the source files from the h5repack test program to a new file h5repacktst.c and removed the old ones (testh5repack*.c).
3. Renamed the binary files from test*.h5 to h5repack*.h5 for easy reference.
4. Modified the shell script to use variables for file names instead of hard coded names
1) added a new parameter to the h5diff function diff_array that contains
the beginning position of the hyperslab, so that the total position in
the array is printed correctly when reading by hyperslabs.
2) added a new test to h5diff that reads and diffs by hyperslabs. The
test reads a 1GB dataset, from which a 1KB hyperslab was written with
differences .
3) added the generation of 2 files to the generator program to test the
h5diff hyperslab read.
4) changed the h5diff binary pre-generated file names to be more
descriptive (e.g, instead of file1.h5, made it h5diff_basic1.h5)
5) changed the name of the h5repack options text file to info.h5repack
Fixes for bugs 676, 228
676: both h5repack and h5diff use H5Dread. In the case of a "big"
dataset, use read/write by hyperslabs the same way h5dump uses. An
arbitrary value of 1GB was defined for "big", i.e, if the dataset is
greater than 1GB, then read/write by hyperslabs
228: use the file type in read/write by default. A new switch -n was
introduced if the user wants to use a native type, which was the
previous use by default.
Added a new test for h5repack that repacks a 1GB dataset
Tested: heping (serial, parallel), sol, copper
New feature
Description:
Check in baseline for compact group revisions, which radically revises the
source code for managing groups and object headers.
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!!
This initiates the "unstable" phase of the 1.7.x branch, leading up
to the 1.8.0 release. Please test this code, but do _NOT_ keep files created
with it - the format will change again before the release and you will not
be able to read your old files!!!

Solution:
There's too many changes to really describe them all, but some of them
include:
- Stop abusing the H5G_entry_t structure and split it into two separate
structures for non-symbol table node use within the library: H5O_loc_t
for object locations in a file and H5G_name_t to store the path to
an opened object. H5G_entry_t is now only used for storing symbol
table entries on disk.
- Retire H5G_namei() in favor of a more general mechanism for traversing
group paths and issuing callbacks on objects located. This gets us out
of the business of hacking H5G_namei() for new features, generally.
- Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t
- Lots more...

new test hor h5repack, to syncronize tests between unix and windows
it requires a new file added

Misc. update:
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.

bug fix
Description:
calling h5diff from the h5repack test script running mpicc , the path of one of the files was not found
Solution:
inserted the full path in the script
Platforms tested:
linux (with mpicc and gcc)
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.
new test

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:
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++)
