[svn-r3479] Purpose:
Bug Fixes
Description:
Fixed a bug in H5Shyper.c where 'contiguous' hyperslabs (i.e. ones which
took up an entire dataset) were not being detected correctly and would
instead be read a part at a time instead of all at once.
Also fixed a bug in the handling of hyperslabs for chunked datasets where
hyperslabs from chunks which weren't aligned on exact dimension bounaries
were not reading/writing data correctly.
Solution:
H5Shyper.c was a single line change from a 'block' size to a 'count' size.
H5Fseq.c changes we much more significant and involved detecting when
non-chunk aligned sequences of data were being written and constructing
hyperslab blocks to pass down to the chunking I/O routine (which only
understand hyperslab I/O requests, not element sequence requests).
This was complicated by the need to align the hyperslabs requested on
dimension boundaries...
Platforms tested:
FreeBSD 4.2. (hawkwind)
