branching: merge with stable

Test for handling of content divergence with public cset using `hg evolve`
==========================================================================

Setup
=====
  $ cat >> $HGRCPATH <<EOF
  > [alias]
  > glog = log -GT "{rev}:{node|short} {desc|firstline}\n {phase} {troubles}\n\n"
  > [phases]
  > publish = False
  > [extensions]
  > rebase =
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

Testing the case when both divergent cset are on the same parent and no-conflict in merging:
-------------------------------------------------------------------------------------

Prepare the repository:

  $ hg init pubdiv
  $ cd pubdiv
  $ for ch in a b; do
  >   echo $ch > $ch;
  >   hg ci -Aqm "added "$ch;
  > done;
  $ hg glog
  @  1:5f6d8a4bf34a added b
  |   draft
  |
  o  0:9092f1db7931 added a
      draft
  

Make an amend and change phase to public:

  $ sed -i "1 i I am first" b
  $ hg amend
  $ hg phase --public

Amend again to create a cset divergent to public one:

  $ hg up 1 --hidden -q
  updated to hidden changeset 5f6d8a4bf34a
  (hidden revision '5f6d8a4bf34a' was rewritten as: 44f360db368f)
  working directory parent is obsolete! (5f6d8a4bf34a)

  $ echo "I am second" >> b
  $ hg ci --amend -m "updated b"
  1 new content-divergent changesets

  $ hg glog
  @  3:dcdaf152280a updated b
  |   draft content-divergent

  | o  2:44f360db368f added b
  |/    public
  |
  o  0:9092f1db7931 added a
      public
  

Lets resolve the public content-divergence:

  $ hg evolve --content-divergent
  merge:[3] updated b
  with: [2] added b
  base: [1] added b
  merging "other" content-divergent changeset '44f360db368f'
  merging b
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  computing new diff
  committed as c1aa9cfb6cf8
  working directory is now at c1aa9cfb6cf8

Following graph log shows that it correctly merged the two divergent csets:

Testing the case when divergence is not created by actual diff change, but because of rebasing:
------------------------------------------------------------------------------------------------

Prepare the repo:

  $ cd ..
  $ hg init rebasediv
  $ cd rebasediv
  $ for ch in a b c; do
  >   echo $ch > $ch;
  >   hg ci -Am "added "$ch;
  > done;
  adding a

  o  1:5f6d8a4bf34a added b
  |   draft
  |
  o  0:9092f1db7931 added a
      draft
  

On server side: a new cset is added based on rev 1 and rev 2 is rebased on newly added cset:

  $ hg up .^ -q
  $ echo d > d
  $ hg ci -Am "added d"
  adding d
  created new head

  $ hg rebase -r 2 -d .
  rebasing 2:155349b645be "added c"

  $ hg glog
  o  4:c0d7ee6604ea added c
  |   draft
  |
  @  3:c9241b0f2d5b added d
  |   draft

  o  1:5f6d8a4bf34a added b
  |   draft
  |
  o  0:9092f1db7931 added a
      draft
  

On user side: user has not pulled yet and amended the rev 2 which created the divergence after pull:
  $ hg up 2 --hidden -q
  updated to hidden changeset 155349b645be
  (hidden revision '155349b645be' was rewritten as: c0d7ee6604ea)
  working directory parent is obsolete! (155349b645be)

  $ echo cc >> c
  $ hg ci --amend -m "updated c"
  2 new content-divergent changesets

Lets change the phase to --public of branch which is pulled from server:
  $ hg phase --public -r 4
  $ hg glog -p
