Testing core behavior to make sure we did not break anything
============================================================

Pushing a first changeset

  $ cd client
  $ echo aaa > aaa
  $ hg add aaa
  $ hg commit -m 'CA'
  $ hg outgoing -G
  comparing with $TESTTMP/main (glob)
  searching for changes
  @  0 default  draft CA
  
  $ hg push
  pushing to $TESTTMP/main (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

Pushing two heads

  $ echo aaa > bbb
  $ hg add bbb
  $ hg commit -m 'CB'
  $ echo aaa > ccc
  $ hg up 'desc(CA)'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg add ccc
  $ hg commit -m 'CC'
  created new head
  $ hg outgoing -G

  @  2 default  draft CC
  
  o  1 default  draft CB
  
  $ hg push

Pushing a new branch

  $ hg branch mountain

  $ hg commit --amend
  $ hg outgoing -G
  comparing with $TESTTMP/main (glob)
  searching for changes
  @  3 mountain  draft CC
  
  $ hg push 
  pushing to $TESTTMP/main (glob)

Testing topic behavior

Test phase move
==================================

setup, two repo knowns about two small topic branch

  $ hg init repoA
  $ hg clone repoA repoB
  updating to branch default
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cat << EOF >> repoA/.hg/hgrc

  $ cat << EOF >> repoB/.hg/hgrc

  > publish=False
  > EOF
  $ cd repoA
  $ echo aaa > base
  $ hg add base
  $ hg commit -m 'CBASE'

  $ hg add aaa
  $ hg topic topicA

We turn different topic to public on each side,

  $ hg -R repoA phase --public topicA
  $ hg -R repoB phase --public topicB

Pushing should complain because it create to heads on default

  $ hg push -R repoA repoB
  pushing to repoB

  no changes found
  abort: push create a new head on branch "default"
