Short version:
==============
MCA base component changes were a bit more extensive than we
anticipated. Please test the following hg tree on your systems before
we bring it into the SVN trunk this Friday evening:
http://www.open-mpi.org/hg/hgwebdir.cgi/jsquyres/mca-base-updates/
Longer version:
===============
Per Josh's and my RFCs, we did a bunch of work in a clone-able HG:
http://www.open-mpi.org/hg/hgwebdir.cgi/jsquyres/mca-base-updates/
After starting, we decided that changing the MCA base revision number
to 2.0.0 also meant changing *ALL* the framework version numbers.
This is because the same components from framework <foo> compiled with
MCA base version 1.x.x would not be binary compatible when compiled
with MCA base version 2.0.0 (the mca_base_component_t struct is a
different size, for example). So it seemed like we needed to make a
large change: we changed both the MCA base and every framework
interface version to v2.0.0, which entails touching every framework
base and every component.
This ended up being a lot bigger change than we anticipated. But at
least the vast majority of the changes are pretty simple s/<version1>/
2.0.0/g kinds of things. The coll fw was a bit tricky because long
ago we prototyped it to handle multiple framework interface versions;
so you'll see a bunch of changes in there.
We have tested what we could, but would *really* appreciate if people
could clone and test this hg before we bring it in to the SVN trunk
Friday evening (my RFC's timeout was this upcoming Friday evening).
Thanks.
