Code cleanup
Description:
Changed prototype for the buffer in Attribute::write from "void *"
to "const void *"

FreeBSD 4.4 (hawkwind)
SunOS 5.7 (arabica)
Linux 6.2 (eirene)
bug fix
Description:
Could not get to compile as parallel program in parallel mode.
That was because I did not include hdf5.h before testing for the
H5_HAVE_PARALLEL macro. (DUMB!)
Solution:
#include hdf5.h first.
Platforms tested:
eirene (parallel)
Code cleanup (sorta)
Description:
When the first versions of the HDF5 library were designed, I remembered
vividly the difficulties of porting code from a 32-bit platform to a 16-bit
platform and asked that people use intn & uintn instead of int & unsigned
int, respectively. However, in hindsight, this was overkill and
unnecessary since we weren't going to be porting the HDF5 library to
16-bit architectures.
Currently, the extra uintn & intn typedefs are causing problems for users
who'd like to include both the HDF5 and HDF4 header files in one source
module (like Kent's h4toh5 library).
Solution:
Changed the uintn & intn's to unsigned and int's respectively.

FreeBSD 4.4 (hawkwind)
Bug fix
Description:
Included all those generated temporary files in the CLEAN target
so that they would be cleaned in "make clean".

Bug fix/code cleanup
Description:
Was using old-style property list for dataset transfer.
Solution:
Switched to use generic property list code for dataset transfer proplist.

Description:
Added perform programs to test the HDF5 library performance. Programs

Platforms tested:
eirene
New feature
Description:
Started this directory for performance measurement programs.
The programs here got compiled but not automatically run (just
like the examples direcotry.)
The programs have existed but now gathered to this one directory.
iopipe.c, chunk.c and overhead.c were from test. perf.c and mpi-perf.c
were from testpar.
Platforms tested:
eirene (serial and parallel).
overhead failed during run due to some property error. This is probably
due to the recent change of properties code.
perf and mpi-perf do not compile correctly for Parallel mode.
Checking them to make them available to others.
Improvement
Description:
The stdout and stderr were both redirected to an output file. This
works fine in tradition sequential Unix machines. But in some
parallel systems (like mpi-jobs in IBM SP), the stderr is merged
with stdout alright but not in the exact order as expected. This
is not deterministic in parallel jobs. So, the test output are
all there but the ordering maynot be as expected.
Solution:
Redirect stderr to separated file and append it to the stdout
file after test-command is executed. Then compare it with
the expected output. This eliminate the assumption that
stdout and stderr must merged in "chronical orders".
The .ddl file are updated by moving all stderr text to the end of the
file.

Bug Fix
Description:
The new way of determining directory information for HDF4 and ZLIB
bombed on me.
Solution:
For some reason, the way I was linking together all of the
"CHECK_LIBRARY" macros wasn't working. I separated them.
Platforms tested:
Kelgia.
Purpose:
1) fix the implementation of image according to image specfication
2) fix two bugs of SDS implemention. the first one is
to handle the unlimited SDS with the first dimensional size set to 0.
the second one is to change the way how HDF5 dataset is written.
Description:
1) mapping 24-bit image to 3D arrays instead of 2D compound datatype.
2) previously forgot considering unlimited SDS with the size set to 0.
3) H5P_set_buffer seems not working well for a extremely small size.
Solution:
1) see above.
2) add a special case to deal with this.
3) don't use H5Pset_buffer.
Platforms tested:
RedHat Zoot 6.2
Bug Fix
Description:
The datatype conversion buffer size was only halfway converted from hsize_t
to size_t and was causing problems. Also, the H5P_peek_<foo> routines have
a bunch of identical code.
Solution:
Finished converting the datatype conversion buffer size to size_t and
cleaned up the implementation of the H5P_peek_<foo> routines to call a
common routine instead of reimplementing a bunch of code.

More code cleanups
Description:
Wrap up the code cleanups for changing the dataset transfer property lists
over to using the generic property list code.
Platforms tested:

Code cleanups, mostly..
Description:
Work on pacifying the SGI compiler to get the generic properties working
correctly with --enable-parallel and --enable-fortran. It's not quite
fixed yet, but I need to head home and these patches help... :-/

New Features!
Description:
Start migrating the internal use of property lists in the library from the
older implementation to the new generic property lists.
Currently, only the dataset transfer property lists are migrated to the
new architecture, all the rest of the property list types are still using
the older architecture.
Also, the backward compatibility features are not implemented yet, so
applications which use dataset transfer properties may need to make the
following changes:
H5Pcreate(H5P_DATASET_XFER) -> H5Pcreate_list(H5P_DATASET_XFER_NEW)
and
H5Pclose(<a dataset transfer property list>) -> H5Pclose_list(id)
This still may have some bugs in it, especially with Fortran, but I should
be wrapping up those later today.

Feature shift
Description:
Take out the v1.2.x compatibility stubs and put in the hooks for v1.4.x
compatibility when needed.
Platforms tested:
FreeBSD 4.3 (hawkwind)
Bug Fix
Description:
H5FD_fapl_copy is being called in H5Pset_driver when copying a dataset
transfer property list instead of H5FD_dxpl_copy and could potentially
cause problems if the file driver information was different.
Solution:
Changed call to H5FD_dxpl_copy() until the generic property code gets
merged in.
Platforms tested:
FreeBSD 4.3 (hawkwind)
Purpose:
Bug Fix
Description:
The dependencies weren't being generated properly. What was
happening, if there was a "." in the path name to the source
directories, it would say, "oh! That matches anything. Dup-dee-do
I'll just mess everything up, then."
Solution:
Escape all occurences of "." with a "\." so that it will match an
actual "." instead of anything.

Bug Fix
Description:
The way we were generating Dependencies and .depend files was broken.
If the $srcdir or other macros began with a ".", then it would match
anything and cause problems since it would then overwrite the
beginning of the header file's path.
Solution:
Wrote a Perl script which can handle this type of weirdness better.
It's only used when the environment is a GNU one with a GCC
compiler...
