New feature.
Description:
The H5Pset_scaleoffset is changed for the scaleoffset filter
to handle both integer and floating-point data. Currently,
the D-scaling method from GRIB has been implemented for
compressing floating-point data.
Solution:
One more parameter is added to the H5Pset_scaleoffset interface
to let user specify what type of data is used and what method
to use as well as corresponding parameters.
Platforms tested:
heping
Misc. update:
Needs to update libtool's version number

collective chunk IO support for AIX 5.x
Description:
NCSA just updated its poe version, this new version will support
MPI complicated derived data type.
So update our configuration file for AIX 5.x.
Solution:
Platforms tested:
copper, no need for others since only AIX 5.x will be affected.
Misc. update:
Bug fix
Description:
Made High-Level Fortran code use automatically generated headers
rather than a separate hardcoded header.
Solution:
Set hdf5/hl/fortran/src to include hdf5/fortran/src, so that it
will find the copy of H5f90i.h in that directory.
Took #include "H5private.h" out of H5f90i.h (and moved it to files
that included H5f90i.h.
Platforms tested:
mir, modi4, pommier
One dtransform test failed with Intel 8.1 C++ compiler.
Turned off the test with assertion of a macro.
Description:
Solution:
Platforms tested:
Intel C++ 8.1 on .Net 2003.
Misc. update:
H5f90i_gen.h has to be copied to fortran/src for windows.
Add this line in the batch file.
Description:
Solution:
Platforms tested:
MSVS 6.0 on windows XP
Misc. update:
Update windows fortran support
Description:
Currently an implementation of automatic generated fortran data type from C has been done for
Linux/Unix platforms. For windows different implementation needs to be developed to make it
consistent with the implementation on Linux/Unix. For the purpose of 1.8 release, we have to add a
new header file. The checking program of the header file on windows will be generated on windows separately.
Solution:
Platforms tested:
VS 6.0 on windows xp.
Misc. update:
Bug fix....
Description:
Despite passing all tests, the previous checkin had a copy/paste typo that
resulted in the tests being run under the wrong conditions.
Solution:
Fixed typo.
Platforms tested:
yet another minor change... copper only.
Misc. update:
bug fix (sorta)
Description:
Rename H5_LLONG_TO_FP_CAST_WORKS to H5_LLONG_TO_FP_CAST_BROKEN
Solution:
Since a test for H5_LLONG_TO_FP_CAST_WORKS is not present in the configure script,
the dtransform test would assume that this cast doesn't work and skip the test. Change the variable around
so that, by default, it is assumed a long long to double cast does work.
Platforms tested:
minor change: copper, sol
Misc. update:
Bug fix
Description:
The intel compiler on windows doesn't support long long to double conversion.
Solution:
Added a flag H5_LLONG_TO_FP_CAST_WORKS. When it is not defined, the data transform will issue
an error when someone tries to perform a transform from long long to double and the long long to double
dtransform test will be skipped.
Platforms tested:
heping, sol, copper
Misc. update:
Configuration feature
Description:
Fortran integer types (not reals) are now automatically detected at
build-time.
Solution:
Two helper programs are used, one to detect what types the Fortran compiler
has access to, and one to generate header files for C and Fortran matching
up types.
Platforms tested:
mir, copper, modi4, pommier (last week)
Misc. update:
MANIFEST updated, H5f90fortran_types.f90 removed from configure.in, since
it is not longer generated by configure.
Output tweak
Description:
Test output in C++ and Fortran directories now puts "C++ API:" or
"Fortran API:" in front of the name of the test being run.
I had overlooked the line of code that caused this to happen.
Solution:
Added HDF_CXX and HDF_FORTRAN variables to C++ and Fortran Makefiles.am.
Platforms tested:
heping (minor change)
Supper 12-byte long double for intel compiler.
Description:
Long double is 12-byte at intel compiler, currently we always set long double to 8-byte.
Change this for intel compiler. This is not the compelete change. H5Tinit.c needs also to be changed to support this.
Solution:
Platforms tested:
Not test yet, since it won't affect other compilers except intel, will test soon.
Misc. update:
long_long to long_long data transform doesn't work with intel compiler on windows.
Description:
Turned off this test.
Solution:
Need corresponding source code changes, will talk with Leon.
Platforms tested:
VS. Net 2003 + Intel 8.1
Misc. update:
Description:
Many warnings about duplicate symbols for various members in the std.
Solution:
Temporarily added -qweaksymbol to suppress linker messages warning
of duplicate symbols since these warnings are harmless.
Note from pSeries and AIX Information Center:
When compiling C++ programs containing extern inline functions,
you can use the -qweaksymbol compiler option to suppress linker
messages warning of duplicate symbols.
Hoping that a better solution is suggested or the problem will be
handled by the compiler in the future.
Platforms tested:
AIX 5.1 (copper)
Bug fix
Description:
Remove declaration of 'prefix' variable that was moved into the h5tools
library.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/CC=g++
Too minor to require h5committest
remove all.zip from HDF5 directory.
Description:
In 1.7, windows projects are directly installed under windows directory.
all.zip should be deprecated.
Solution:
Read install_windows.txt for details on how to build and install HDF5 library on
windows.
Platforms tested:
Misc. update:
Bug fix.
Description:
When there were errors in the test, program still just call MPI_FINALIZE
and failed to attempt to exit with some error code so that calling
programs like make be informed of the exceptions.
Solution:
Call MPI_ABORT if error is detected. Though MPI_ABORT does not
guarantee 100% failure report, it has the best chance.
Also made dimension incompatible as a real error.
Platforms tested:
Did not h5committest but tested in heping PP only since this
is a simple fix.
Bug fix/code cleanup
Description:
Add tests to determine that very long (64K+) object names are working.
Fixed a couple of bugs in h5dump where they weren't...
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
Use getenv_all for determining HDF5_PARAPREFIX instead of getenv
Description:
the environment variable HDF5_PARAPREFIX is now determined collectively, instead of
having each task call getenv.
Solution:
Environment variables set for task 0 often do not propogate to other tasks which
leads to obscure and hard to track down bugs. getenv_all was written to overcome
this by having all tasks query a single task for the value of its environment.
Eventually, all calls to getenv will be migrated to use getenv_all. For now,
only HDF5_PARAPREFIX will be determined this way.
Platforms tested:
heping pp, sol pp
Misc. update:
Code cleanup
Description:
Clean up various warnings reported by the Windows team.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Feature - libtool shared library versioning
Description:
Libtool provides a mechanism for different versions of the same shared
library to be distinguished. Now this is applied to HDF5 when it is
built as a shared library.
Solution:
The version number is stored in config/lt_vers.am, and included in
src/Makefile.am.
This number will be automatically updated by bin/h5vers; developers
only need to update it when they change the API.
*** IMPORTANT ***
Any time the API changes, the version number in config/lt_vers.am must
be updated!
Platforms tested:
mir, eirene, verbena, modi4
Misc. update:
Description: Some memory buffers were allocated by HDmalloc() but weren't cleaned
up before use.
Solution: Use HDmemset() to 0 set the buffers.
Platforms tested: h5committest.
Bug fix
Description:
Opening a dataset (or named datatype) with "." for the name and using a
group ID for the location ID was not returning an error value.
Solution:
Check the type of the object before attempting to open it (internally,
using a group ID and "." for the name maps to the group object).
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
Too minor to require h5committest
Bug fix
Description:
Correct typo in "base array" free list macro when free list macros are
disabled.

Turning off collective irregular selection feature for this platform
because the MPI package doesn't support MPI complicated derived data
type.
Description:
Solution:
Add the macro hdf5_mpi_complex_derived_datatype_works=${hdf5_mpi_complex_derived_datatype_works='no'}
at the end of config file.
Platforms tested:
Won't affect other platform and too minor to go to PSC cluster for testing.
Misc. update:
