merge: back out single-parent fast-forward merge This backs out changeset: 13158:9e7e24052745 user: Mads Kiilerich <mads@kiilerich.com> date: Tue Dec 07 03:29:21 2010 +0100 summary: merge: fast-forward merge with descendant Before named branches, the invariants were: a) "merges" always have two parents b) p1 is not linearly related to p2 Adding named branches made (b) problematic, so the above patch was introduced, which fixed (b) but broke (a). After discussion, we decided that the invariants should be: a) "merges" always have two parents b) p1 is not linearly related to p2 OR p1 and p2 are on different branches

        $ hg init

        $ echo a > a

        $ hg ci -Ama

        adding a

        $ echo b > b

        $ hg branch b

        marked working directory as branch b

        $ hg ci -Amb

        adding b

        $ hg co -C 0

        0 files updated, 0 files merged, 1 files removed, 0 files unresolved

      Fast-forward:

        $ hg merge b

        1 files updated, 0 files merged, 0 files removed, 0 files unresolved

        (branch merge, don't forget to commit)

        $ hg ci -Ammerge

      Bogus fast-forward should fail:

        $ hg merge b

        abort: merging with a working directory ancestor has no effect
