templates: don't alias keywords directly Putting the same function twice in the registry results in duplicate doc strings and therefore confusing "hg help template" output.

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  working directory parent is obsolete!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:[2] added b
  with: [3] updated b
  base: [1] added b
  updating to "local" side of the conflict: 44f360db368f
  merging "other" content-divergent changeset 'dcdaf152280a'
  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:

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

  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
