Tests the resolution of public content divergence: main cases

=============================================================

This file intend to cover all the common cases of public content divergence.

That is all the variant of:

parent: same/different

relocation: [no-]conflict

merging: [no-]conflict

Setup

  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

Testing when same parent, no conflict:

--------------------------------------

Prepare the repository:

  $ hg init pubdiv1

  $ cd pubdiv1

  $ for ch in a b; do

  >   echo $ch > $ch;

  >   hg ci -Aqm "added "$ch;

  > done;

      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  working directory parent is obsolete!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"

Lets resolve the public content-divergence:

  $ hg evolve --content-divergent

  merge:[2] added b

  with: [3] updated b

  base: [1] added b

  merging b

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

  committed as c1aa9cfb6cf8

  working directory is now at c1aa9cfb6cf8

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