topic: setup 'topic' value for working ctx
The way amend work in core change in e8a7c1a0565a. The intermediate commit
disappear and we can no longer rely on it to carry the topic value to amend. To
fix this, we ensure the current topic value can be retrieved through the
`workingctx.extra()` value. Since there is no way to carry a "missing" key
information in a way that survives and "dict.update" call. We also has to
introduce hacking behavior about a special empty value for topic.
====================================
Testing head checking code: Case C-2
====================================
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 C: case were the branch is only partially obsoleted
TestCase 2: 2 changeset branch, only the base is rewritten
.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * 1 new changesets branches superceeding only the base of the old one
.. * The old branch is still alive (base is obsolete, head is alive)
..
.. expected-result:
..
.. * push denied

Test setup
----------
$ mkdir C2
$ cd C2
$ setuprepos
creating basic server and client repo
updating to branch default
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd server
$ mkcommit B0
$ cd ../client
$ hg pull
pulling from $TESTTMP/C2/server (glob)
searching for changes
adding changesets
adding manifests
adding file changes
added 1 changesets with 1 changes to 1 files
(run 'hg update' to get a working copy)
$ hg up 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ mkcommit A1
created new head
$ hg debugobsolete `getid "desc(A0)" ` `getid "desc(A1)"`
obsoleted 1 changesets

Actual testing
--------------
$ hg push --rev 'desc(A1)'
pushing to $TESTTMP/C2/server (glob)
searching for changes
abort: push creates new remote head f6082bc4ffef!
(merge or see 'hg help push' for details about pushing new heads)
