Misc. update:
Feature (bug fix)
Description:
Added a new configure file specifically for the IA64 platform
in which ecc and efc are the default compilers.
Also added all the Fortran special setup in the fortran version
Platforms tested:
no h5committest since this is a IA64 platform stuff.
Tested in Titan.

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.
1) Linux 2.4 (eirene)

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)

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.
Improvement
Description:
Added a 5 seconds timeout to the PING command so that it can detect
host not online quicker.
Platforms tested:
The three platforms tests do not cover this command.
Test it in eirene where it is usually run.
Misc. update:
Bug Fix & Update
Description:
FPHDF5 was creating files which didn't have the EOA field in the
superblock set correctly. It turns out that the SAP was keeping this
information to itself instead of giving it to the client processes.
Naughty SAP!
Solution:
Have the SAP send this information back to the clients so that they
can update the superblock as necessary. This now creates a file (with
just the root group) that looks correct! Only problem is that there's
extra file space being allocated. Also, at program termination,
there's an infinite loop...
Platforms tested:
H5committests (run by hand on burrwhite, arabica, and modi4)
Misc. update:
New test feature
Description:
Added the VFD_LIST definition to support the "make check-vfd" tests.
Platforms tested:
h5committested.
Since check-vfd is not invoked by default, I went to each machine
to invoke them by hand. The target worked fine but there were
errors reported from those driver tests. (Those errors were beyond
the scope of this make target test.)
Misc. update:
New test feature
Description:
The various virtual file drivers (multi, family, core, ...)
are not tested automatically. One would have to do it by hand
by setenv HDF5_DRIVER <driver> and then do gmake check in test/.
Solution:
Added a new target, check-vfd, which will take the list from
$VFD_LIST and run 'make check' with each of its members.
Platforms tested:
h5committested.
Since check-vfd is not invoked by default, I went to each machine
to invoke them by hand. The target worked fine but there were
errors reported from those driver tests. (Those errors were beyond
the scope of this make target test.)
Misc. update:
Bug fix.
Description:
n_test must be inited to 1 when it is for tests within one machine.
Undid my previous mistake.
Platforms tested:
Eirene.
Did not do the h5committest because this is a script and if it works
in one machine, it most like will work in all Unix platform.
Misc. update:
new feature and some bug fixes
Description:
Add a new feature to "skip" some tests.
Sometimes, a machine has problem (e.g. titan and sleipnir having AFS
problems). Sometimes some feature in a machine is temporary off (e.g.,
PGI compilers in eirene.) The tests will be reported being SKIPPED
which will be reminder to remove the skipping once the problem is fixed.
I installed the skipping control in snaptest.cfg rather than in
allhostsfile to have a finer control to skip just a subset of the
tests of a machine, rather than skipping the all tests of a machine.
Bug fixes: fixed the miscounting of number of tests ran. It was
reporting one too many.
Platforms tested:
Only tested in eirene since eirene is the one uses it directly.
Misc. update:
Purpose:
Adding descriptions of new library features to the RM
Description:
H5Pset_fapl_log: Added new 'buf_size' parameter.
New 'flags' parameter replaced 'verbosity' parameter,
requiring new table describing 20 available flags.
H5Pset_filter: Added valid 'filter' parameter values.
Modified for Fletcher32 EDC filter.
H5Pget_filter: Added return value descriptions.
H5Pset_layout & H5Pget_layout: Modified for compact datasets.
Added the following new functions:
H5Pset_fletcher32
H5Pset_edc_check & H5Pget_edc_check
H5Pset_filter_callback
H5Pset_shuffle
Platforms tested:
Safari
IE 6
Bug fix/code cleanup/new feature
Description:
Fix h5debug to work correctly again, with all the changes over the past
few months.
Improved and cleaned up debugging output available in h5debug.
Platforms tested:
FreeBSD 4.7 (sleipnir)
Purpose: Bug fix.
Description: When I added support for filters, I forgot to add
fortan man pages file to the MANIFEST file.
When I run chkmanifest, I discovered that there was also
a typo ( ./dac/Makefile.in instead of ./doc/Makefile.in )
Solution: added ./doc/html/fortran/h5z_FORTRAN.html and chnages "a" to "o"
Platforms tested: arabica with bin/chkmanifest
Misc. update:
Bug fix
Description:
The $RUNPARALLEL is set even when parallel mode is not used.
Then it is used to launch some parallel natured test (e.g. example/ph5example)
which is not compiled to be so. That created some unnecessary problem
in some situation (e.g., Copper cannot "poe a.out" from an AFS space
because of the missing AFS token system bug.
Solution:
Setup RUNPARALLEL only when parallel mode is enabled.
Platforms tested:
Only tested in Copper since the change applies to IBM machines only.
(note that v1.4 will fail by default due to a problem when the default
production mode is used. But that is an error not related to this config file)
Misc. update:
Bug fix and Update
Description:
From Quincey's comments on the code I checked in last night:
- In H5F_close call, the "private" processes should call the
H5F_flush with the "CLEAR_ONLY" flag.
- There's no need for a special case for FPHDF5 in the
FD_real_alloc function since FPHDF5 doesn't define an alloc
function.
- The return type of H5Pset_fapl_fphdf5 should be herr_t instead
of hid_t. I don't know how it got that way in the first place.
- The variable names for MPI types and the structure typedefs
should be switched: H5FP_request/H5FP_request_t to
H5FP_request_t/H5FP_request and so on.
- In the H5FP.c module, I was commiting the H5FP_request MPI
datatype but using the wrong offset field...
Platforms tested:
Linux...will test on others, but these are mostly FPHDF5 changes.
