Description: a new dataspace, null dataspace.
Solution: it's a dataspace without any element. This is a staged check-in.
After daily test succeeds, will add a test.
Platforms tested: h5committest
Misc. update: RELEASE.txt
Description: integer-float software conversion. There are some
print commands left in the source code. Will clean them up once
no problem is found in test.
Platforms tested: h5committest.
Misc. update: RELEASE.txt
bug fix
Description:
the fletcher filter used a temporary 2 byte word buffer to compute the checksum.
this is non portable between big-endian/little endian.
Solution:
replaced with a buffer of 1 byte type
Platforms tested:
linux
solaris
solaris 64 bit
AIX
windows
Misc. update:
Code cleanup/bug fix
Description:
Fix configuration files to allow 64-bit compilation of the library with
a 64-bit version of zlib.
Solution:
Moved important compiler flags settings from CC macro to CFLAGS macro.
Instead of setting CC (F9X, CXX) environment variable for compiling for 64-bit
code, users should just set the CFLAGS (FFLAGS, CXXFLAGS) to -q64.
Updated INSTALL file to reflect this change.
Platforms tested:
IBM p690 (copper) w/parallel, FORTRAN, C++, srcdir.
Platforms specific - h5committest does not apply.
Description: software conversion from float to integer(integer to float hasn't
be done yet).
Solution: This is the software conversion.
Platforms tested: h5committest
Misc. update: RELEASE.txt
Purpose:
replaced name of delete filter with remove filter for the new function H5Premove_filter

Misc. update:
New Feature. (Contributed by Robb)
Description:
Allow h5ls to specify a VFL with the '--vfl=' command line flag.
Add MPI-I/O & MPI-POSIX VFL drivers to list of drivers available for
h5ls and h5dump.
Platforms tested:
FreeBSD 4.9 (sleipnir) w/parallel
h5committested
Bug fix.
Description:
Allow H5Tget_native_type() to handle opaque fields in compound datatypes.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor to require h5committest
Bug fix/optimization
Description:
Address slowdown in MPI-I/O file metadata operations that was introduced
mid-stream. We now _require_ a POSIX compliant parallel file system for the
MPI-I/O file driver (as well as for the MPI-POSIX file driver).
Also optimized file open operation when the file is being created by
reducing the number of collective & syncronizing calls.
Additionally, refactor the MPI routines into a common place, eliminating
duplicated code.
Platforms tested:
FreeBSD 4.9 (sleipnir) w/parallel
h5committest
Code cleanup
Description:
Add C++ and FORTRAN wrappers for new H5Pdelete_filter routine, along with
documentation and a note in the release notes.
Platforms tested:
FreeBSD 4.9 (sleipnir)
Linux 2.4 (verbena) w/ C++ and FORTRAN
Too minor for full h5committest
Add tests & docs
Description:
Added tests for the recent B-tree bug fixes & document their fix in the
release notes.
Platforms tested:
FreeBSD 4.9 (sleipnir)
Too minor to require h5committest
Bug fix
Description:
Correct two problems with variable-length datatypes in datasets:
- When overwriting an entire dataset, writing the fill value to the
file would be skipped, causing problems for VL datatypes when
objects in the file had been unlinked (and thus the space in the
file was not all zeros)
- When an application has set a fill-value for a dataset and the
dataset's datatype contained a VL datatype, the library was filling
space on disk with the memory form of the VL information, instead
of the disk form.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Bug fix
Description:
When two property lists are compared, the H5Pequal routine was just
comparing the raw information for the property values. This causes problems
when the raw information contains pointers to other information.
Solution:
Allow a 'compare' callback to be registered for properties, so that a user
application get perform the comparison itself, allowing for "deep" compares of
the property value.
This was exported to the H5Pregister & H5Pinsert routines in the development
branch, but not the release branch.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Purpose: Maintenance
Description: Fortran APIs MAC OS X port for IBM XL Fortran compiler
Solution: Brought back changes from 1.6 branch
Platforms tested: pommier, h5comittested; this time h5committest
complained about copperpp directory and didn't run;
tests on verbena and sol passed.
Misc. update:
Bug fix
Description:
Fix small memory leak of fill-value information inside the library.
Solution:
"reset" the fill-value object header message, so that the internal buffer
gets freed.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor to require h5committest
Bug fix
Description:
Range check the szip 'pixels per block' against the chunk size of the
dataset when attempting to create a new dataset, since the szip library
requires the PPB to be at least the size of the fastest changing dimension
in the chunk.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor for h5committest
Bug fix
Description:
Fixed bug in hyperslab iteration where certain combinations of flattened
and non-flattened dimensions would cause incorrect locations to be iterated
over.
Platforms tested:
FreeBSD 4.9 (sleipnir)

Code cleanup, bug fixes
Description:
Wrap up rest of changes necessary for fixing the "short" MPI-I/O read
problem that Robb reported.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor to require h5committest
Bug fix
Description:
Attributes which were created with scalar dataspaces were reporting their
dataspace as a simple dataspace when queried later.
Solution:
Fix the dataspace handling code when reading in the attribute message from
the file to set the extent type correctly.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor to require h5committest
Bug fix.
Description:
Using a selection offset with hyperslab selections in chunked datasets
was getting into an infinite loop and hanging the application.
Solution:
Apply the selection offset to the hyperslab selection properly.
Platforms tested:
FreeBSD 4.9 (sleipnir) w & w/o parallel
h5committest
Bug fix
Description:
Make a copy of the index value for H5Giterate and use that instead of
dereferencing the index pointer.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor to need h5committest
Bug fix
Description:
Variable length strings and sequences with NULL pointers were not handled
by library, causing problems access the data. This also affected fill values
for variable-length datatypes.
Solution:
Address the issues in the library by detecting NULL sequences/strings
and avoid trying to convert them.
Patched up dumper to display NULL sequences/strings.
