Bug fix.
Description:
The nbit filter test case (compound datatype with no-op field)
can not pass the daily test on heping and eirene when the
enable-production option is set with configure and PGI compiler
is used. It will generate segmentation fault.
Solution:
It was found that the seg fault disappears when adding a new
index variable in the test case and using it instead of using
an existing index variable twice during initialization.
This does not make much sense since previous codes is logically
equivalent to the changed codes. So, some other factors beyond
the test case codes may have caused the problem.

heping
Misc. update:
Description: When stream driver was not enabled, H5FD_STREAM variable
was not define. Fortran compilation failed since H5FD_STREAM
was needed to set up fortran global variables.
Solution: Followed MPIO driver model and defined H5FD_STREAM to be -1
when driver is not enabled.
Platforms tested: heping with --enable(disable)-stream-vfd
Misc. update:
Purpose:
Fix the daily test failure of collective irregular test in modi4.
Description:
The original test passed with new SGI compiler. Albert verified this from
the SGI machine at DOE. The compiler version number at modi4 is 7.3.1.3m, the compiler version number at DOE is 7.4.2m. compiler at modi4 is old and SGI may fix some bugs during the updating of their compiler.
Solution:
At configuration file IRIX.6.x, set the macro MPI_COMPLEX_DERIVED_DATATYPE to no. In that way, HDF5 library won't call derived datatype routine in the test.
Platforms tested:
modi4
Misc. update:
Bug fix.
Description:
The irregular chunk IO tests do not work for processes sizes larger than 3.
Added a check of number of processes and skip the irregular chunk IO
tests if number of processes are larger than 3.
Revamped the tests of collective chunk IO tests too.
Platforms tested:
Tested in mir.
Misc. update:
New feature.
Description:
The scaleoffset filter previously does not use macros to handle
different integer datatype situations.
Solution:
Added macros in the filter for better maintenance and clarity of codes.
Platforms tested:
heping, copper, shanti
Misc. update:
Bug fix.
Description:
Data file name is hardcoded to be in current directory which does not
necessarily support MPIO. Changed it to /tmp/sds.h5 for slightly larger
chance of success but the eventual solution is to set it according to
environment variables. Patch it this way for now.
Platforms tested:
mir.
Misc. update:
Minor feature
Description:
If a user configures without C++ or Fortran, 'make' will not recurse into
c++ or fortran directories. However, if the user cd's into these
directories and 'makes,' the Makefiles will attempt to build interfaces
that have not been configured, usually failing.
In an unrelated but minor change, src/H5detect should be compiled with
the -g flag to disable compiler optimizations since it is only
executed once.
Solution:
Make it harder for users to try to compile interfaces that have not been
configured by making c++, fortran, and hl directories not recurse into
their subdirectories unless they have been configured.
Thus, 'make' in /fortran/src will break if Fortran has not been configured,
but 'make' in /fortran will not break.
Platforms tested:
mir, modi4, copper
Misc. update:
Description: h5pget_driver_f function returned information that could not
be interpreted by fortran application
Solution: Defined Fortran global variables that correspond to
the C H5FD_<driver_name> variables at the Fortran library
initialization time.
Platforms tested: heping with PGI compilers, sol 64-bit and copper parallel

Improvement
Description:
Changed headers in Fortran directories to use H5_FC_FUNC macro
from H5pubconf.h rather than FC_FUNC macro from H5config.h.
This is better practice and works better with the Windows projects.
Platforms tested:
heping, Windows
Description: Removed support for SRB driver
Solution: Removed or modified appropriate files; ran reconfigure
to regenerate Makefile.in and configure files.
Platforms tested: heping and shanti
Misc. update: ran bin/chkmanifest on heping
New feature.
Description:
The N-Bit filter needs a test case for no-op datatypes.
Solution:
A test case was added to test a compound datatype with
N-Bit fields and no-op fields.
Platforms tested:
heping, shanti
Misc. update:
Bug fix.
Description:
The current HDF5 library call H5Tget_size when called by the filter
does not give the correct disk size for varible-length and variable-length
string. The filter needs to have another way, if possible, to get their
sizes.
Solution:
The filter can only solve this problem if varible-length and variable-length
string is a member of compound datatype. The filter does not support the
situation where an array datatype has variable-length or variable-length
string as its base datatype.
Platforms tested:
heping, shanti
Misc. update:
FOrtran is using macro FC_FUNC or H5_FC_FUNC
Has to update windows H5pubconf.h to be consistent with the
change.

Platforms tested:
heping, copper, tungsten, cobalt, SDSC TG.
Misc. update:
Feature
Description:
Added new function, getenv_all (only for parallel builds)
Solution:
getenv_all is a collective version of getenv. It is used to the return the value of
an environment variable in another task and can be used to synchronize all of the
environment variables used by all of the tasks. This helps to fix problems that commonly crop up
(like with HDF5_PARAPREFIX) when an environment variable does not propogate to other tasks.
This commit only includes the function. Future commits will replace the various getenv calls with getenv_all calls.
Platforms tested:
heping, sol, copper
Misc. update:
Description: Yesterday, dtypes.c was split into two programs, dtypes.c and dt_atomic.c.
After dt_atomic.c was added, dtypes.c remained the same as before waiting for the
daily test to pass. While dt_atomic.c turned out fine today, the test in dt_atomic.c
was taken out from dtypes.c. There's also some minor change in dt_atomic.c.

Support collective IO for irregular selection.
Description:
Solution:
Platforms tested:
Linux with MPICH
AIX with mpcc_r
Linux with ChaMPIO
Altix with intel
Misc. update:
Activating collective IO supports for irregular selction inside HDF5 dataset.
This support doesn't include to build the final complicated MPI derived datatype support for chunking storage.
Description:
Support collective chunk IO for both contiguous and chunking storage for irregular selection( using H5S_SELECT_OR for multiple hyperslab selection)
Solution:
Using MPI derived datatype to realize this feature.
Problems still need to be investigated:
Big size irregular hyperslab selection test may cause MPI hang or abnormalexit with MPICH family on various platforms. This is really hard to debug since sometimes it can work and sometimes it cannot work. We will continue investigating those cases. This may not be parallel HDF5 bugs since with the recent version of poe at IBM platforms, all tests passed.
Platforms tested:
1. Linux heping 2.4.21-27.0.1 with mpich
2. AIX 5.1 copper with mpcc_r
3. Altix cobalt SGI linux 2.4.21-sgi304rp05031014_10149 with icc -lmpi
4. Linux Cluster SDSC TG, intel 8-r2 with mpich 1.2.5
5. NCSA Linux Cluster Tungsten, MPICH-TCP-1.2.5.2, Intel 8.0 under lustre
6. NCSA Linux Cluster Tungsten, MPICH-LAM-INTEL711, sometimes not working
7. NCSA Linux CLuster Tungsten, champion-pro-1.2.0-3, not working for other collective IO tests, but work for irregular selection collective IO test.

Bug fix
Description:
When chkmanifest failed, output is not dumped to failed detail section
and people tend to ignore it.
Solution:
Buffer the output of chkmanifest in a file and dump it to failed detail
section if it fails. Else, just output to standout.
Platforms tested:
Tested by hand in heping.
Improvement
Description:
Dumping the beginning 10 lines of log files does not give much
useful information and they sort of mix up with the last 30 lines.

Purpose:
Bug fix
Description:
Automake relies on the helper script depcomp to handle dependency tracking.
This script was from an older version of automake, and was generating
warnings on copper and sol.
Solution:
Updated bin/depcomp and bin/missing scripts.

Description: Split test/dtypes.c because it's so big. Moved all integer-integer,
floating-floating, integer-floating, floating-integer, derived integer, derived
floating conversion tests to a new test program, dt_atomic.c. The test remains
the same basically.
Platforms tested: fuss and h5committest
Misc. update: MANIFEST
Configuration feature
Description:
Different Fortran compilers mangle function names in different ways
(upper case, lower case, adding underscores). To link between
Fortran and C functions, we need to know what a given function's
name is under a given compiler.
Solution:
Use autoconf's FC_WRAPPERS check to determine the Fortran
naming scheme and define the FC_FUNC_ macro to name our
functions (in H5f90proto.h). Removed references to
our old FNAME macro, as well as flags that indicated whether
function names were upper or lower case.
Platforms tested:
mir, pommier, modi4, copper, more
Feature
Description:
Added support for conditional compilation of parallel Fortran
examples. No such examples exist currently, but it should be
possible to add them to the Makefile.am with no fuss and have
them compile only when parallel is enabled.

Misc. update:
Description: In the last checkin, the fix wasn't quite correct. This round simply corrects the mistake
from last round, especially the endianess was left out.
Platforms tested: shanti, modi4, fuss - these machines cover both little and big endians.
