Sometimes after Wolfgang pulls a repo (or applies patches directly to
mainline) a subsequent pull of another repo will have a merge conflict. It
would be nice to catch them early

<random thoughts>
What I am thinking is a patch tracker (not manager) which basically has an
internal queue of unapplied (to mainline) patches. When a patch gets
submitted, it will be sanity checked (checkpatch). If the sanity checks
pass (or are overruled) then a git-apply test is run. If this passes, the
patch gets added to the queue. The mailing list gets informed that the
patch has been 'provisionally accepted' and has been queued for formal
review.

If a patch get's NACK'd, or the auto-build infrastructure determines that
the patch breaks the build, the patch gets removed from the queue. When a
patch gets removed from the mailing list gets informed that the patch has
been removed from the queue and a new revision needs to be resubmitted.

If a new revision of a patch is submitted, the patch tracker attempts to
replace the old patch at the same location. If the new patch cannot be
applied, it (and the old patch) gets removed from the queue

I'm thinking that the patch tracker can keep track of which repo the patch
belongs to. If the patch tracker had a non-mailing list interface that
triggered the patch tracker to apply the patch to the corresponding repo,
that would be great.

So any time a patch is committed to mainline or a repo, the patch tracker
would remove that patch from the queue then redo the git-apply test to
each patch left in the queue.
</random thoughts>

Graeme
