[svn-r7018] Purpose:
Bug fix
Description:
The dataset's modification time was getting set whenever raw data was
written with H5Dwrite. Unfortunately, this is a metadata change (which are
required to be performed collectively) and H5Dwrite may be called independently
from a parallel program, resulting in metadata cache corruption and/or program
hangs.
Solution:
Don't update the modification time when raw data it written. :-(
Platforms tested:
FreeBSD 4.8 (sleipnir) w/parallel
h5committest
Misc. update:
Noted in release notes and also sent to Frank for updating the docs.
