Description:
- Added functions to query chunk information:
H5Dget_num_chunks(dset_id, fspace_id, *nchunks)
Gets the number of written chunks that intersect with the given
dataspace. However, in this version, the intersection is not
yet completed. Thus, the number of all written chunks will be
returned.
H5Dget_chunk_info_by_coord(dset_id, *offset, *filter_mask, *addr, *size)
Given a chunk's logical coordinates, returns the chunk's filter,
address, and size.
H5Dget_chunk_info(dset_id, fspace_id, index, *offset, *filter_mask, *addr, *size)
Given a chunk's index, returns the chunk's logical coordinates, filter,
address, and size. The chunk belongs to a set of chunks that have
nonempty intersection with the specified dataspace. However, in
this version, the intersection is not yet completed, and the index
is of all the written chunks.
These functions comply with VOL.
- Fixed some oversights found in the library for the tests in chunk_info.c
to work correctly. The returned value from a callback function was not
checked in H5EA_iterate(), H5FA_iterate(), and H5D__none_idx_iterate().
This oversight caused a callback function to continue iterating even though
it's supposed to stop.
Platforms tested:
Linux/64 (jelly)
Linux/64 (platypus)
Darwin (osx1011test)
