How to compare sets of changesets between 2 Mercurial branches?

Question

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).

Answer 1

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.
