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
Description: Bump up the version number before giving a tar ball to the MAC HDF5
Fortran user.
Solution: run bin/h5vers on eirene
Platforms tested: N/A
Misc. update:
Purpose: Maintenance
Description: Added information about how to build HDF5 Fortran Library
(use --disable-shared --enable-static with configure)
Solution: N/A
Platforms tested: N/A
Misc. update:
Purpose: Maintenance
Description: Added Fortran support for MAC OS X
Solution: This port was tested only for IBM XL Fortran compiler
version 8.1 Beta.
Few things to remember:
1. do not use AFS to build Fortran; compiler
for some reason cannot find *.mod files that
were successfully compiled.
2. Fortran Library can be built only with --disable-shared
--enable-static flags.
Platforms tested: pommier, h5committested (it is amasing, but iot works
really nicely! Albert, Thank you!)
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)
too minor to require h5committest
Code cleanup
Description:
Note in the release notes that the short MPI-I/O bug has been fixed and
also clean up the configure.in a bit.
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
directory. This eliminates the problem that the builder may not
have permission to install in the default install directory.
It also allows multiple builds in the same host or multiple srcdir
using the same source.
Platforms tested:
Eirene plus eyeballing of changes.
Misc. update:
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.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Code optimization
Description:
Improved integer & floating-point datatype conversions by removing some
corner cases. Got rid of algorithm which walked the buffer of elements to
convert backwards, switching to algorithm which computes the non-overlapping
space in the buffer and repeatedly converts it in the forward direction.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Cray SV1 & T3E (T90 is not accessible)
Bug fix & code cleanups
Description:
Change our use of MPI derived datatypes to not create datatypes with
"0-sized" lengths, which causes the LANL Q machine to hang.
Also, get rid of "prefer MPI derived datatypes" environment variable since
it has no advantage.
Platforms tested:
FreeBSD 4.9 (sleipnir) w & w/o parallel
h5committest
Bug fix
Description:
Single hyperslab selections (which were set with only one call to
H5Sselect_hyperslab) that had dimensions that could be "flattened" but were
interspersed with dimensions that could not be flattened were not correctly
handled, causing core dumps.
Solution:
Re-work "flattening" code to handle this case properly.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Description: Changes version to 1.6.1-post0 and updated
RELEASE.txt and HISTORY.txt filese fro the new version.
Solution: N/A
Platforms tested: N/A
Misc. update:
Description: I run bin/release to create an hdf5-1.6.1 release tar
ball. Now I am checking in modified files before
tagging the release.
Solution: N/A
Platforms tested: N/A
Misc. update:
Purpose: Maintenance for the 1.6.1 release
Description: Updated "platforms tested" section using the reports
sent out for the hdf5-1.6.1-pre1 testing; added
h5pget_driver_f subroutine to the "Known problems" section.
Solution: N/A
