Bug Fix
Description:
There was a problem with having a lot of groups nested together. We
could only handle 1024 characters at most, but, in a parallel program
especially, it could occur that there were lots and lots of groups
and would be more than 1024.
Solution:
I made the "objname" part of the obj_t structure a pointer instead of
a fixed size. Added code to allocate/deallocate the memory we need
for it. Had to fix how the "prefix" was being handled in the h5dump
program. It was also set to only 1024 characters in length. I made it
dynamic.
Added a test case...Go me!
Platforms tested:
Linux, Solaris
Purpose:
Small Fix
Description:
Changed how the list of drivers were listed from:
{ "driver1",
"driver2",
/* ... */
"drivern",
#ifdef FOO
"driverm"
#endif
};
to
{ "driver1"
,"driver2"
/* ... */
,"drivern"
#ifdef FOO
,"driverm"
#endif
};
since it's a nicer way of doing the same thing without the annoying
warning of an extraneous , if FOO isn't defined.

Removing the DPSS (gridstorage) driver source code.
Description:
The DPSS (using Grid-Storage) driver is retired.
Removed the configure option with-gridstorage from configure.in.
Cvs remove the following files
./src/H5FDdpss.c
./src/H5FDdpss.h
./test/dpss_read.c
./test/dpss_write.c
Regenerated Dependencies files (some had to be hand-edited since
'make depend' did not cover them.)
Removed reference to DPSS Virtual file driver from H5F.c.
Platforms tested:
modi4 (Parallel; -with-gass=...), eirene, arabica (fortran, cxx).
Bug Fix.
Description:
The H5Rget_object_type function could not get the object type for dataset
region references.
Solution:
Added a new function, H5Rget_obj_type, to replace H5Rget_object_type.
The new function requires the reference type as an additional parameter,
in order to allow queries on different reference types to be performed
correctly.
Platforms tested:
FreeBSD 4.4. (sleipnir)
Code cleanup
Description:
Windows is generating hundreds of warnings from some of the practices in
the library. Mostly, they are because size_t is 32-bit and hsize_t is
64-bit on Windows and we were carelessly casting the larger values down to
the smaller ones without checking for overflow.
Also, some other small code cleanups,etc.
Solution:
Re-worked some algorithms to eliminate the casts and also added more
overflow checking for assignments and function parameters which needed
casts.
Kent did most of the work, I just went over his changes and fit them into
the the library code a bit better.
Platforms tested:
FreeBSD 4.4 (hawkwind)
Kludge
Description:
Since we're only about halfway through converting the internal use of
property lists from the "old way" to the generic property lists, we turned
off snapshots to avoid exposing lots of API changes to users, until the
APIs settled down.
Getting the snapshots rolling again seems to have become a priority, so
some changes are going to have to be made now that were going to be
postponed until we were completely finished with the conversion. This
requires that the old API functions be able to deal with both the old
and new property lists smoothly.
Solution:
Kludge together the property list code so that they can transparently handle
dealing with both the old and new property lists
Platforms tested:
FreeBSD 4.4 (hawkwind)
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... :-/
Platforms tested:

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)
Purpose:
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...
Platforms tested:
Linux
Purpose:
Bug Fix/Feature Add
Description:
Added new flag ("-f" and "--family") to allow user to specify which
file driver to use to open the file. If they don't specify anything,
then it defaults to the old behaviour of trying each driver in turn
until one actually opens the file.
If the driver the user specified doesn't succeed in opening the
file, then we do NOT try other file drivers.
Platforms tested:
Linux
Update
Description:
Updated the way the subsetting data is retrieved. It now does it one
row of blocks at a time. It may still run out of memory, but this is
at least a good first step.
Also, the start parameter defaults to (0, 0, ...) if it isn't
specified.
Platforms tested:
Linux
Feature Add
Description:
This is the first (alpha) version of h5tools which does subsetting
according to the subsetting document. There's still some niceties
which need to be worked out, but this is the ground work.
Platforms tested:
Linux
Purpose:
fixing the format of dumper output for windows test
Description:
New dumptest includes the feature that an error of the output will be put into stderr in linux
On windows, that stderr will not be redirected into the output file and the comparsion between the expected file and the dumper output is not correct.
Solution:
change fprintf(stderr .....) at h5tool_util.c into fprintf(stdout ......) so that it fits the comparison.
Platforms tested:
windows 2000
Code Cleanup
Description:
Moved some code out which wasn't specific to the h5tools into the
h5tools_utils and h5tools_str modules. Also started on adding the
subsetting feature to the dumping.
Platforms tested:
Linux
Code Movement
Description:
Moved some functions which worked only with the h5tools_str_t
structure from the h5tools module to the h5tools_str module.
Platforms tested:
Linux
New Modules
Description:
Separated the "generic" functions out of the h5tools module into
their own separate module to make things a bit nicer to deal with.
Platforms tested:
Linux
More Subsetting
Description:
Wanted to do a check-in of the current subsetting stuff. The
command-line parsing was already in there. I now added the feature to
the h5dump_t structure and it now outputs the new SUBSET DDL stuff in
the correct format. It doesn't yet do the actual subsetting, but
we're getting there...

Linux
Bug Fix
Description:
Some platforms (gondolin) don't necessarily have the vsnprintf
function.
Solution:
Changed it to HDvsnprintf and added a header for H5private to include
it...

Bug Fix
Description:
We were trying to build the talign test program before the library
was actually built.
Solution:
Moved talign test to the lib directory since it belongs with the
library anyway.
