Subject: [OMPI devel] Mercurial discussion in Chicago
From: Jeff Squyres (jsquyres_at_[hidden])

We had a good discussion this earlier today about Mercurial. Here's
the conclusions we came to:

- We're a little nervous about the current state of Mercurial support
tools; they seem a little immature at this point (e.g., the Trac
Mercurial plugin is kinda weak). As such, it seems like waiting for a
little while before converting seems like a good idea.

- In the interim, we'll do two things (specific details TBD):

1. Setup a read-only Mercurial mirror of the OMPI SVN repository. The
general idea is that this could be an "official" Mercurial repo that
is a) updated on a regular/automated basis (e.g., every hour or
better), and b) is available for read-only to the world. Commits
still have to go through SVN.

2. Setup an official way for OMPI core members to publish and
collaborate on their own Mercurial repositories, probably similar to
what is currently available on http://www.open-mpi.org/hg/. This
would allow OMPI core members to publish their own "/tmp-public" HG
repositories.

The idea is to get actual, practical experience with Mercurial and be
able to take advantage of some of the distributed / branching+merging
functionality of Mercurial, build up concrete lists of what we like/
don't like about Mercurial, etc.
