Tests the resolution of content divergence: basic cases
=======================================================

This file intend to cover basic case of content divergence. See the other test
file for more advanced cases.

Basic test of divergence: two divergent changesets with the same parents
With --all --any we dedupe the divergent and solve the divergence once

  $ hg init test1
  $ cd test1
  $ echo a > a
  $ hg ci -Aqm "added a"
  $ echo b > b
  $ hg ci -Aqm "added b"

  $ hg up .^
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo bdivergent > bdivergent1
  $ hg ci -Am "divergent"
  adding bdivergent1
  created new head

  $ hg up .^
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo bdivergent > bdivergent2
  $ hg ci -Am "divergent"
  adding bdivergent2
  created new head

  $ hg prune -s 8374d2ddc3a4 "desc('added b')"
  1 changesets pruned
  $ hg prune -s 593c57f2117e "desc('added b')" --hidden
  1 changesets pruned
  2 new content-divergent changesets

  $ hg log -G

  $ cd ..

Extra setup
-----------

(the test below were initially in a different file)

  $ hg init cdiv
  $ cd cdiv
  $ 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;

  $ hg glog

  |   () [default] draft
  o  3:ca1b80f7960a added c

Merging branch difference
-------------------------

Creating content-divergence with branch change where base, divergent and other
have different branches

  $ hg branch -r . foobar
  changed branch on 1 changesets

  $ hg up c41c793e0ef1 --hidden
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  updated to hidden changeset c41c793e0ef1
  (hidden revision 'c41c793e0ef1' was rewritten as: 9e5dffcb3d48)
  working directory parent is obsolete! (c41c793e0ef1)
  (use 'hg evolve' to update to its successor: 9e5dffcb3d48)
  $ echo bar > d
  $ hg branch watwat
  marked working directory as branch watwat
  $ hg amend
  2 new content-divergent changesets

  $ hg glog
  @  6:264b04f771fb added d
  |   () [watwat] draft
  | *  5:9e5dffcb3d48 added d

  o  0:8fa14d15e168 added hgignore
      () [default] draft

  $ hg evolve --content-divergent --config ui.interactive=True<<EOF
  > c
  > EOF
  merge:[6] added d
  with: [5] added d
  base: [4] added d
  merging "other" content-divergent changeset '9e5dffcb3d48'
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  content divergent changesets on different branches.
  choose branch for the resolution changeset. (a) default or (b) watwat or (c) foobar?  c
  working directory is now at 0ac42f1bc15c

  $ hg glog
  @  7:0ac42f1bc15c added d

Testing merging of commit messages
-----------------------------------

When base and one of the divergent has same commit messages and other divergent
has different one

  $ echo wat > d
  $ hg amend

  $ hg up .^
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ echo bar > d
  $ hg ci -Aqm "added a d with bar in it, expect some beers"

  $ hg prune -r 0ac42f1bc15c -s . --hidden
  1 changesets pruned
  2 new content-divergent changesets
