[svn-r14247] Description:
- Refactored H5D_flush to use H5I_search for iterating through
datasets, instead of building array of dataset IDs.
- Cache dataset's dataspace modifications (from calls to
H5Dset_extent) until flush/close.
These changes give an ~15% improvement in speed for my "append records
to lots of 1-D datasets" benchmark.

[svn-r22213] Update tests to use new H5Z_class3_t struct, and H5Z_CLASS_T_VERS_3 macro. Also
minor cleanup in H5Z aligned malloc functions.
Tested: fedora
[svn-r21943] Fix bug in aligned memory filter implementation. Improper comparison could
result in unnecessary invalidation of aligned memory state in filter pipeline.
Tested: durandal
[svn-r21907] Purpose: Add persistent file alignment option
Description:
Added two new functions, H5Pset_persist_alignment and H5Pget_persist_alignment.
These allow the user to set a persistent file alignment, which overrides that
set with H5Pset_alignment, and is is followed every time the file is written to,
even if it has been closed and reopened. In addition, aligned blocks of data
will "reserve" a multiple of the alignment size, allowing this potentially
largersize to be written to with...
[svn-r21906] Purpose: Add support foraligned memory allocation to filters
Description: Versioned H5Z_func_t, adding new lib_data parameter to H5Z_func2_t.
Added new version of H5Z_class_t to include H5Z_func2_t. Added new functions
H5Zaligned_malloc, H5Zaligned_free and H5Zaligned_realloc to allow filters to
support aligned buffers so the data can be immediately written when using a file
driver that requires alignment (i.e. direct).
Tested: durandal
[svn-r21827] Add configure check for posix_memalign, prevent compilation of affected code
if it's not found.
Change H5MM_aligned_free to only mark the DXPL as unaligned if it previously
marked the freed buffer as aligned.
Tested: jam
[svn-r21820] Purpose: refactor direct I/O implementation
Description:
- Consolidated aligned memory properties into a single dxpl property.
- The f->lf->must_align is now the canonical way to determine if a file needs
to have memory aligned. The file driver feature flag is only used by
H5FD_open to determine how to initialize the aligned memory fields.
- Removed dxpl parameter from H5MM_aligned_malloc, etc. - callers are now
responsible for manipulating the property themselves. lf->m...
[svn-r21492] Purpose: Refactor direct I/O branch to be more maintainable
Description:
Add new driver feature flag, H5FD_FEAT_ALIGNED_MEM, to indicate if the driver
can benefit from aligned memory blocks. Removed several H5_HAVE_DIRECT
ifdefs and changed code that checked for the direct driver specifically to
instead check fro the feature flag.
Added new public functions H5MMaligned_malloc and H5MMaligned_free, and
removed H5Pset_aligned_mem and H5Pget_aligned_mem, so the user no longer has...
[svn-r20107] Purpose: Add enhancements to direct I/O driver
Description:
Adds support to chunk cache to allocate memory that can be used directly with
the direct I/O driver. This will work when the file alignment is set properly
and reading or writing unfiltered datasets, or when reading filtered datasets.
When writing filtered datasets, the driver will still have to reallocate the
buffer (unless the filters didn't reallocate).
Also added public functions H5Pset_aligned_mem() and H5Pget_al...
