I've got a (remote) Hg repository with a couple branches. I want to verify that branch A has every changeset that branch B has (it may have more, and that's OK).
Is there an easy way to do this with just hg?
I can write a little shell script to do it, but it seems like the sort of thing that might come up a lot, so maybe there's an easy built-in way.
This will show any ancestors of changeset b which are not an ancestor of changeset a:
hg log -r "ancestors(b) and not ancestors(a)"
This should show you which changes still need to be merged from B to A if you give the head of branch B for b, and the head of branch A for a.
