evolve: merge commit messages while resolving content-divergence (issue5877)
While resolving content-divergence, there can be divergence in commit messages
too which should be resolved.
This patch uses the hg's internal merge API's to merge commit messages of
divergent changesets with predecessor as the base.
In case of conflicts, we fallback to divergent's commit message which should be
changed in future. We should pop up the editor with the commit message and the
conflict markers and let user fix that.
Tests are added for the functionality added.
This feature requires mercurial 3.0
(and the `only()` revset is 3.0 specific)
$ (hg help revset | grep '"only(' > /dev/null) || exit 80
Test creation of obsolescence marker by path import
$ hg init auto-obsolete

$ echo A > a
$ hg commit -Am A
adding a
$ echo B > b
$ hg commit -Am B
adding b
$ hg up '.^'
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ echo C > c
$ hg commit -Am C
