Testing head checking code: Case E-1

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

Mercurial checks for the introduction of new heads on push. Evolution comes

into play to detect if existing branches on the server are being replaced by

some of the new one we push.

This case is part of a series of tests checking this behavior.

Category F: case involving changeset on multiple topic

TestCase 1: moving a branch to another location

Test setup

----------

  $ mkdir E1

  $ cd E1

  $ setuprepos

  creating basic server and client repo

  updating to branch default

  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ cd client

  $ hg topic Z

  marked working directory as topic: Z

  $ mkcommit B0

  active topic 'Z' grew its first changeset

  (see 'hg help topics' for more information)

  $ hg push

  pushing to $TESTTMP/E1/server

  searching for changes

  adding changesets

  adding manifests

  adding file changes

  added 1 changesets with 1 changes to 1 files

  $ hg up 0

  0 files updated, 0 files merged, 2 files removed, 0 files unresolved

  $ hg topic Z

  marked working directory as topic: Z

  $ mkcommit B1

  $ hg debugobsolete `getid "desc(B0)" ` `getid "desc(B1)"`

  1 new obsolescence markers

  obsoleted 1 changesets

  $ hg log -G --hidden
