I haven't gotten a chance to really play with this yet, so I'm going more off the
comments here- I apologize if these answers should be obvious, but I'm not familiar
enough with some of the code.
- Is there an easy way to tell if the repo is/was self contained? (Maybe
- Is the 'self-contained' bit to limit overhead on each pull, or is there another
reason this can't ensure the result is self contained? 'Push' and 'outgoing -S'
recognize (almost) everything going in the other direction, so it might be nice
to have the same capability with a form of pull. (I may have found a push bug
that I haven't gotten back to yet.)
- The full subrepo gets pulled, even revs not committed to the parent? I think
that's a good thing, because regularly get burned when I 'pull -u' the tree to
another machine and then go to apply the rest of a patch queue to the subrepo.
I'll try to experiment with this some in the next few days. I ran into issues with
what I'm working on (push, outgoing) with deeply nested subrepos, and also when a
parent locks in an earlier subrepo version. I wonder if deeply nested subrepos will
be a problem here since hgsubrepo.pull() doesn't walk its subrepos and pull them.
