Bug fix
Description:
Array testing routine is creatint huge arrays on the function stack
which causes a segmentation fault on Linux & FreeBSD when threadsafe
support is enabled.
Solution:
Allocate data for test dynamically instead of automatically.
In general, this should be the preferred method for all data arrays.
Platforms tested:
FreeBSD 4.7 (sleipnir) w/threadsafe enabled.
Code Cleanup & New Tests
Description:
tmisc.c:
Switched from using H5_HAVE_COMPRESSION flag in favor of
H5_HAVE_FILTER_DEFLATE.
dsets.c:
Switched from using H5_HAVE_COMPRESSION flag in favor of
H5_HAVE_FILTER_DEFLATE.
Refactored I/O filter tests to allow new filters to be [more] easily
added.
Added tests for shuffle & deflate+shuffle I/O filters (if the filter(s)
are enabled).
Added test for creating a new dataset with a filter that is not
available.
Added test for attempting to read a dataset created with a filter that
is not available.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir)
Purpose:
Add a testing case for shuffling algorithm.
Description:
A control test:
Since shuffling 8-bit array should not change the original result; so we use a
8-bit array to test whether after shuffling the array keeps the same values.
Solution:
Platforms tested:
eirene,arabica,modi4
Misc. update:
Update MANIFEST if you add or remove any file.
Update release_docs/RELEASE for bug fixes, new features, etc.
Update applicable document files too.
Purpose:
New function.
Description:
H5Dget_offset returns the offset of a dataset's data relative to the
beginning of a file.
Platforms tested:
arabica(simple function, one test should be enough.)
Misc. update:
RELEASE.txt
New feature
Description:
Add support for scalar dataspaces in parallel I/O.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
Also, FreeBSD 4.7 (sleipnir) serial & parallel
Misc. update:
Update release_docs/RELEASE for bug fixes, new features, etc.
Improvement
Description:
fillval will fail to find the pre-exist data file if it is run
in --srcdir mode without setting $srcdir properly. This is
setup properly in the Makefile but unsuspecting users trying just
./fillval were puzzled by the failure.
Solution:
put in a more descriptive error message with a possible remedy.
Platforms tested:
Modi4 only since this is just adding a printf statment.

IRIX64 6.5 (modi4) w/FORTRAN & parallel
Internal feature.
Description:
To complement the "get the class's path" functionality, there needs to be
a way to open a generic property class with a path.
Solution:
Implement the "open a class by path" functionality. Also, add internal
testing routines.
Platforms tested:
FreeBSD 4.6 (sleipnir) (too small for triple testing)
New internal feature.
Description:
Need some way to determine the "full path" for a generic property class,
i.e. where is this class in the class hierarchy, in relation to its parent
class, etc.
Solution:
Added an internal function "H5P_get_class_path" and a testing function
"H5Pget_class_path_test" that builds the full path of a generic property
class back to the top of its class hierarchy.
This implementation uses '/' characters to delimit the components of the
class path, but no special cases are currently supported for having a '/'
character as part of the actual class name. Should this become an issue,
code to support (and test) it will need to be added.
Platforms tested:
FreeBSD 4.6 (sleipnir) (not major enough to justify triple-test)
Bug fix
Description:
H5Pequal's algorithm for comparing property lists wasn't allowing property
lists that are equal but had the properties inserted in a different order
in the list's hash table.
Solution:
Re-did the algorithm a bit to compare the properties better.
Platforms tested:
FreeBSD 4.6 (sleipnir) (minor enough to not need triple testing)
Purpose:
a bug fix
Description:
modify the condition check for the file close degree.
Platforms tested:
Linux 2.2(eirene), Solaris 2.7(arabica), IRIX64 6.5(modi4)
Purpose:

Description:
When a file is opened for a second time, file close degree is supposed to
be either the same as the first open, or default as the first open is also
default.
Platforms tested:

which has 2 new fields 'name' and 'old_name'
A new private function was introduced H5G_ent_copy, that does a deep copy
between 2 symbol table entries

w/filters, to verify that filter is applied correctly.
Platforms tested:
FreeBSD 4.6 (sleipnir) w/parallel
Purpose:
Design for compact dataset
Description:
Compact dataset is stored in the header message for dataset layout.
Platforms tested:
arabica, eirene.
Additional regression tests & bug fixes
Description:
There was no testing for the H5Dget_storage_size function and it seemed to
be having problems with compressed, chunked datasets, so write some tests
to verify that its working correctly.
Also, fix case for allocating storage early for chunked datasets
Platforms tested:
FreeBSD 4.6 (sleipnir) serial & parallel
Code cleanup
Description:
Clean up a few warnings which were showing up with --enable-production
turned on.
Platforms tested:
FreeBSD 4.6 (sleipnir) serial & parallel
Update, Bug Fix, and Feature Add
Description:
- Updated how AC_{ENABLE,WITH} help messages were being generated.
Autoconf now gives you an AC_HELP_STRING macro to use to create
them.
- Fixed the problem with Linux LFS on RedHat 7.3 machines. It wasn't
finding getdents64(), so we can't rely on that being present
anymore...
- Added GPFS detection and setting.
- Updated how compression is specified. It's no longer necessary to
test for HAVE_ZLIB_H, HAVE_LIBZ, and HAVE_COMPRESS2. The one macro
{H5_}HAVE_COMPRESSION takes care of all of these.
Solution:
Changed the check for Linux LFS from looking for getdents() to
looking at the version number of the kernel (using the uname -r
command). You can still override with the --enable-linux-lfs switch
if you really believe that your <2.4 kernel has LFS support.
Platforms tested:
Linux (2.2 and 2.4)
Purpose:
New Test VL memory leak.
Description:
Test to see if VL type memory leaks when data is overwritten.
Platforms tested:
Linux 2.2(eirene), IRIX 6.5(paz).
Purpose:
Bug fix.
Description:
This test fails on TRUE64 system because a compound variable(fill_ctype
in test_rdwr) wasn't initialized.
Solution:
Initialize to zero.
Platforms tested:
Pittsburg's True64(lemieux) system.
Bug fix
Description:
I/O on "Regular" hyperslab selections could fail to transfer correctly
if the number of elements in the selection's row did now fit "evenly"
into the buffer being used for the transfer.
Solution:
Correct the calculation of the block & count offsets within the optimized
"regular" hyperslab routines.
Platforms tested:
FreeBSD 4.5 (sleipnir)
