Beyond sniffing the patch to ensure it looks reasonable, the best a
committer can do is to test it on the platforms he or she has available.
After that we rely on the diversity of the community building and
testing the code to catch any problems; i.e. the change doesn't
necessarily end with the commit, it may still have to be backed out.
And the hope is that we'll have the project's CI system running on lots
of places.
How will we define which changes should be backed out?
Do you mean that we first define list of "supported" platforms
and then we will roll back all the changes that reportedly break
build on one of that platform?
Yes - I think that we'll eventually get to that state formally, and
we're there now informally. I suspect that a change to support IPF that
broke x86 would be backed out w/o a complaint :)
What would be the procedure to add a new platform to the list of
supported ones? (Well I assume it's a vote, but what are the criteria
to be used in that vote?)
I think that having "criteria" for use in a vote misses the point -
because otherwise we'd determine based on the criteria and not need to vote.
I think that it will be based on having people interested in working on
it and size of user population. If we decide that we're going to
support a platform, it's a lot of work we're taking on....

Thanks,

There is no guarantee of the stability of HEAD, we only get that by
taking a snapshot and everyone testing it with all platforms (c.f. say
Eclipse that does have a centralized build system).
