|
|
|
|
|
|
|
|
|
|
|
|
|
|

Purpose: Maintenance
Description: H5_SZIP_CHIP_OPTION_MASK was deleted from the list
of the available parameters for the H5Pset_szip function.
Solution: Updated Fortran source, tests and documentation
to reflect this change.
Platforms tested: arabica (too small for h5committest)

Purpose:
To more carefully describe the
-- behavior of H5Pset_external
-- appropriate usage of H5Pset_shuffle
Description:
H5Pset_external
Add notes that first H5Pset_external call sets the dataset as EXTERNAL
and identifies the first file in the series of external files that
will hold the dataset; subsequent calls identify additional files;
all external files must be declared before the dataset is created;
and the library will create files that don't yet exist on the system
at the time that H5Dwrite is called to write data to that file.
H5Pset_shuffle
Added notes regarding usage of H5Pset_shuffle in concert with a
compression filter.
And, as always, a few copy edits.

Purpose:
SZIP and more general filter updates
Description:
Added SZIP to the introductory paragraphs and as appropriate in
the Fortran subroutine descriptions.
Revised the introductory discussion, which had previously focussed
on one compression filter, to allow for multiple filters of
different types.
Added list of filters currently distributed with HDF5 to intro.
Also some copy edits and minor formatting.

Code optimization & bug fix
Description:
When dimension information is being stored in the storage layout message
on disk, it is stored as 32-bit quantities, possibly truncating the dimension
information, if a dimension is greater than 32-bits in size.
Solution:
Fix the storage layout message problem by revising file format to not store
dimension information, since it is already available in the dataspace.
Also revise the storage layout data structures to be more compartmentalized
for the information for contiguous, chunked and compact storage.

Purpose:
Bugfixes in H5Gset_comment, h5gget_comment_f, and h5gset_comment_f.
(Follow-on to the H5Gget_comment bugfix of last week.)
Description:
Changed C parameter descriptions to indicate the following:
'loc_id' can be file, group, dataset, or named datatype.
'name' can be '.' if 'loc_id' fully describes the object.
'name' is ignored if 'loc_id' is a dataset or named datatype.
Modified h5gget_comment_f and h5gset_comment_f notes accordingly.
Copy edits in H5Gget/set_comment and h5gget/set_comment_f.

Purpose:
H5Gget_comment bugfix
Description:
H5Gget_comment: Changed "Description" text and "Parameters"
descriptions to indicate the following:
'loc_id' can be file, group, dataset, or named datatype.
'name' can be '.' if 'loc_id' fully describes the object.
'name' is ignored if 'loc_id' is a dataset or nemed datatype.
Also corrected the fact that the 'name' parameter description
referred to setting the comment rather than retriving it.

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.

FreeBSD 4.9 (sleipnir) w/parallel
