Bug Fix
Description:
On AIX machines, the number of script interpreters which ran the
testh5dump.sh script would strip too many of the quotes away, causing
problems if you're quoting something with a space in it.
Solution:
Just got rid of the spaces and used ',' instead.
Platforms tested:
AIX and Linux
Migrate from configure macros of XYZ_ABC to H5_XYZ_ABC
Description:
configure generates many macros definitions on the fly and
were stored in src/H5config.h which is included by H5public.h.
But other software that uses hdf5 may also run their own configure.
There can be a clash in macro name space. We decided awhile ago
to prepend all generated macros with "H5_" to avoid conflicts.
The process has started and this commit completes it (at least attempt
to).
Solution:
Many macros symbols (e.g. SIZEOF_xxx and HAVE_xxx were changed to
H5_SIZEOF_xxx and H5_HAVE_xxx). Then H5private.h no longer includes
H5config.h. This cuts H5config.h away from HDF5 source code.
Pending issues:
The module of fortran and pablo are to be resolved in a different
commit.
Platforms tested:
eirene (parallel), arabica (solaris 7 --enable-fortran, --enable-cxx)
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
Oops
Description:
I added files for testing the group comments dumping feature, but
didn't actually add it to the testh5dump.sh script.
Solution:
Added it.
Platforms tested:
Linux
Purpose:
Feature Add
Description:
Added support for dumping Group Comments. This involved a
modification of the DDL as well.
Solution:
Steal code from h5ls and put it in the h5dump. The ddl.html file was
updated as normal. And a test was created...

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)
Code cleanup for better compatibility with C++ compilers
Description:
C++ compilers are choking on our C code, for various reasons:
we used our UNUSED macro incorrectly when referring to pointer types
we used various C++ keywords as variables, etc.
we incremented enum's with the ++ operator.
Solution:
Changed variables, etc.to avoid C++ keywords (new, class, typename, typeid,
template)
Fixed usage of UNUSED macro from this:
char UNUSED *c
to this:
char * UNUSED c
Switched the enums from x++ to x=x+1
Platforms tested:
FreeBSD 4.4 (hawkwind)
Purpose:
Bug Fix
Description:
Some so-called "operating systems" (*cough*Windows*cough*) can't
handle large string sizes.
Solution:
Replace the Usage string with individual strings which all call
fprintf() themselves.
Platforms tested:

Purpose:
Bug Fix
Description:
Object IDs command-line options weren't being picked up.
Solution:
The wrong flag was being checked for. Changed the flag from "v" to
"i", which is what the documentation says.
Platforms tested:
Linux
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.
Platforms tested:
FreeBSD 4.4 (hawkwind)
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".
Platforms tested:
tested in v1.4. Folded it into v1.5.
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... :-/

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.

Description:
If specifying --stride, it was checking for the wrong short-form of
the command-line parameters.

Changed the 'T' to 'S' which is the new short form for the stride
option.

Update
Description:
If the count for a subset isn't specified, then we default to the
remainder of the dataset.
Solution:
Check for the count to be specified. If not, then find the dimensions
of the dataset and subtract from the the "start" parameter.
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.

Bug Fix.
Description:
Kent is correct about the malloc error. It's harmless if it's not
needed anyway.
Solution:
Removed the #ifdef's since all platforms should use this.
Platforms tested:
Linux
Purpose:
a bug fix on windows(possible on other platforms)
Description:
not allocating enough space for a string at dump_all for debug version
a string tmp is defined at dump_all(....),
The memory that is allocated to tmp is malloc(strlen(prefix)+strlen(name)+1);
However, there is one testing case : strlen(prefix) is 0 and
tmp is allocated in the following:
strcat(tmp,"/");
strcat(tmp,name);
....
free(tmp);
the program fails when freeing tmp for debug (dll) version on windows 2000
Solution:
For windows platform:
allocate memory strlen(prefix)+strlen(name)+2
Platforms tested:
[machines you have tested the changed version. This is absolute
important. Test it out on at least two or three different platforms
such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and
64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]
Update
Description:
Updated to reflect the new naming of APIs in the h5tools library.
I.e., things which were once named "h5dump_*" now have the "h5tools_"
prefix instead.
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...

Previous changes to the h5dumper were lost. This patch includes
better memory management of XML formatted strings along with the bug
fixes for the XML code.
Solution:
Merged the XML patch with the previous code.

Purpose:
Bug fix.
Description:
Order of elements in groups is wrong. (Need to find out why
h5gen accepted this at all.)
Note that test output had to be corrected in some cases.
