Fix
Description:
Previous changes in the configure were overwritten.
Solution:
Updated configure.in with the changes that were lost.
Platforms tested:
Linux & Modi4.
Misc. update:
To update szip support on windows
Description:
Windows project files have been updatd
Solution:
Windows DLL doesnot work with szip compression. Look into it now.
Windows Static works with szip compression.
Platforms tested:
Since no HDF5 source code has been touched, only test on windows 2000 VS 6.0.
Misc. update:
Purpose: Maintenance
Description: There was an old h5import (h5import.c) tool in the misc directory.
The tool created 8-bit integer datasets , it was never tested and/or
supported.
Solution: We decided to rename old h5import.c to h5createU8.c. The new name reflects what
actually old tool does. New executable h5createU8 is built in the misc directory.
h5import.c file (old one) is still in the misc directory, but h5import executable
is not built. (Sorry if I confused you!)
Platforms tested: vebena, arabica, modi4 were tested
Misc. update:
Purpose: New tool
Description: Pankaj created h5import tool long time ago. I am finally checking
the source code in for the 1.6 release.
Known problems: h5import test will crash if srcdir option
is used; will be fixed before the release.
Solution:
Platforms tested: vebena, arabica, modi4 were tested. h5import tests passed
I also tested on arabica with srcdir option to make sure that
there is a problem when srcdir is used. After that I disabled
h5import tests. Daily tests will build h5import, but will not run
h5import tests.
Misc. update:
Code cleanup
Description:
Updated copyright.
Removed szip-specific testing in favor of standard testing, now that bugs
in the szip filter are fixed.
Updated to latest version of H5Pset_szip API
Solution:
Platforms tested:
FreeBSD 4.8 (sleipnir)
IRIX64 6.5 (modi4) w/parallel
Misc. update:
Code cleanup & bug fix
Description:
Cleaned up comments & copyright statement.
Blocks which were unable to be compressed were missing the "length" prefix,
causing the decompression routine to fail.
Solution:
Always add "length" prefix to all blocks, even ones the fail to compress.
Platforms tested:
FreeBSD 4.8 (sleipnir)
IRIX64 6.5 (modi4) w/parallel
Misc. update:
Code cleanup
Description:
Added lots of comments to existing filters, so they are easier to understand
and use as examples for future filters. Cleaned up various bits of code, etc.
Solution:
Platforms tested:
FreeBSD 4.8 (sleipnir)
IRIX64 6.5 (modi4) w/parallel
Misc. update:
Code cleanup (sorta)
Description:
The H5Pset_szip API call was forcing users to pass in their parameters
in the same way as the internal representation of the filter parameters used
by the library (as an array of unsigned values).
Solution:
Changed to pass in separate parameters in a more user-friendly format.
Platforms tested:
FreeBSD 4.8 (sleipnir)
IRIX64 6.5 (modi4) w/parallel
Misc. update:

Solution:
Used the correct pointer to get the file_id...
Platforms tested:
Modi4
Misc. update:
Update & Bug Fix
Description:
The "free" protocol was missing. Added that to the server side.
When doing a "create" of a file (with no other data structures
created), the freespace in the file wasn't being reclaimed.
Solution:
After adding the free protocol, we put the burden of running through
the FD_free function on the SAP instead of each client.
Platforms tested:
Linux
Misc. update:
To add tests for szip compression in HDF5
Description:
Three tests were added:
1) szip filter itself
3) szip + shuffle + fletch32
2) fletch32 + shuffle + szip
Solution:
Since H5Dget_storagesize returns 0(Quincey can fix it or it may be gone),
I create another function called test_internal_filter_szip, which is the almost the same
as test_internal_filter but comments out H5Dget_storage_size function.
Platforms tested:
Since there are changes of configure.in and configure,I didn't use h5committest.
I tested with four platforms.
1) Linux 2.4 (eirene) 2) Solaris 2.7(arabic
3) windows 2000(VS 6.0) 4) SGI IRIX6.5-64(modi4)
For test 1)-3), only basic C tests were done For modi4 test, I tested 64-bit C,parallel and fortran.
All tests passed, except a warning message from szip library when checksum is used in some order, which doesn't cause any real problems.
Misc. update:
To support szip compression in HDF5
Description:
This is where szip filter function is located.
Solution:
The filter function composes of "encode" and "decode" part, which
is similar as deflate filter.
One critical difference is:
when szip decompresses the data, it needs to know the buffer size to hold
the decompressed data in advance.
Currently it's hard for HDF5 lib to give the buffer size easily. So to avoid
this problem, in each chunk, we add a small header to hold the buffer size of
each chunk. The code will use UINT32 ENCODE and UINT32 DECODE to finish this
part of work.
Platforms tested:
Since there are changes of configure.in and configure,I didn't use h5committest.
I tested with four platforms.
1) Linux 2.4 (eirene)
2) Solaris 2.7(arabica)
3) windows 2000(VS 6.0)
4) SGI IRIX6.5-64(modi4)
For test 1)-3), only basic C tests were done
For modi4 test, I tested 64-bit C,parallel and fortran.
All tests passed, except a warning message from szip library when checksum is used in some order, which doesn't
e any real problems.
Misc. update:
To support szip compression in HDF5
Description:
szip compression support is required by NASA ESDIS. The compression algorithm
is good for scientific data. In HDF5, we add another filter
function to make szip as a default compression package as we did for gzip(or zlib).
In this check-in, a new function called H5Pset_szip was added into H5Pdcpl.c, this
function is very similar to H5Pset_deflate. The only difference is SZIP needs
four parameters from the user to get the compression done while gzip needs only one.
So we pass a pointer to this function instead of an integer number.
The description of the four parameters of szip should be in different
documents.
H5Z.c and other header files were simply modified to have HDF5 know szip.
Solution:
See the decription
Platforms tested:
Since there are changes of configure.in and configure,I didn't use h5committest.
I tested with four platforms.

Description:
szip compression support is required by NASA ESDIS. The compression algorithm
is a good compression algorithm for scientific data. In HDF5, we add another filter
function to make szip as a default compression package as we did for gzip(or zlib).
H5config.in needs to be regenerated by autoheader for SZIP flags.
Solution:
A new file called H5Zszip.c will be added in the Makefile.in
Flags like: HAVE_FILTER_SZIP should be auto-generated by autoheader.
Platforms tested:
Since there are changes of configure.in and configure,I didn't use h5committest. I tested with four platforms.

Misc. update:
This is the first check-in message related to szip support at HDF5 1.6 release
Description:
szip compression support is required by NASA ESDIS. The compression algorithm
is a good compression algorithm for scientific data. In HDF5, we add another filter
function to make szip as a default compression package as we did for gzip(or zlib).
Solution:
In the configure.in and configure, I handled szip exactly the same as what zlib was built into
the HDF5.
Currently if you don't specify in the configure command line with:
./configure --with-szlib=/.....
Unless you put your szip library in your path,you will build the same HDF5 library like before.
Also, I only use static szip library to test with HDF5.
Platforms tested:
Since there are changes of configure.in and configure,I didn't use h5committest.
I tested with four platforms.
1) Linux 2.4 (eirene)

ALl tests passed, except a warning message from szip library when checksum is used in some order, which doesn't cause any real problems.
Misc. update:
New Feature
Description:
Some machine has a different hostname from its official name (e.g., copper
is called Cu12) and some machine name are dynamic aliases (e.g., titan is
mapped user01 or user02). Some names are cryptic (who could remember
hn0? are platinum hosts while user0? are for titan). We had to hardcode
those names into the snaptest.cfg file. An ongoing maintenance PAIN.
Solution:
Added -configname <name> option where
"use <name> as hostname in the parsing of the snaptest configure file"
Changed RSH code to append the hostname used in the Allhostfile. Now, we
need not worry about machine name mapped to a different host and it is
much cleaner to match up entries between allhostfile and snaptest.cfg files.
Platforms tested:
Did not use h5committest which does not cover this code.
Tested in eirene, titan, platinum and copper.
Misc. update:
Update
Description:
Updated (and in some cases added) the copyright statement.
Platforms tested:
Linux (Comment changes...only tested if they compile)
Misc. update:

Description:
Updated the Copyright statement
Platforms tested:
Linux (This change is only in the comments, so I just check that the
modules still compile)
Misc. update:
Bug fix
Description:
test/dtypes failed badly when -O is used. Trying to recompile test/*
code without -O did not eliminate the errors. So, the failure is
deep in the hdf5 library.
Solution:
For now, removed '-O' from $PROD_CFLAGS so that enable-production will use
no optimization. Need to find out what exactly trigger the errors.
Platforms tested:
Did not do h5committest because this is an AIX configure change only.
Tested it in Copper. Need to test it on other offsite machines.
Misc. update:
Updated release_docs/RELEASE.
