evolve: run in a single transaction
This speeds up `hg evolve --all` of a stack of 24 commits in the hg
repo from 11.5s to 3.7s (3x). As can be seen in the tests, it also
avoid some warnings about transiently unstable commits.
=======================================================
Tests the resolution of content divergence: interrupted
=======================================================
This file intend to cover case where evolve has to be interrupted.
This test aims at gather test case for --abort, --continue and --stop
Tests for the --abort flag for `hg evolve` command while content-divergence resolution
======================================================================================
The `--abort` flag aborts the interrupted evolve by undoing all the work which
was done during resolution i.e. stripping new changesets created, moving
bookmarks back, moving working directory back.
This test contains cases when `hg evolve` is doing content-divergence resolution.
Setup

Tests for the --stop flag for `hg evolve` command while resolving content-divergence
==================================================================================
The `--stop` flag stops the interrupted evolution and delete the state file so
user can do other things and comeback and do evolution later on
This is testing cases when `hg evolve` command is doing content-divergence resolution.
Setup
=====
$ hg init stoprepo
$ cd stoprepo
$ echo ".*\.orig" > .hgignore
$ hg add .hgignore
$ hg ci -m "added hgignore"
$ for ch in a b c d; do echo foo > $ch; hg add $ch; hg ci -qm "added "$ch; done;
