topic: add more branchcache entries to test-topic-flow-publish-flag.t It seems these new entries started appearing after the recent-ish refactoring of branchcache in core. Now the server and the client have the same branch cache data on disk, which is probably for the best. The actual output with changeset hashes is: branch2-base:c0155e8ec55a9b46d415d5b13a319d0c80e26e9d o double//slash branch2-immutable:c0155e8ec55a9b46d415d5b13a319d0c80e26e9d o double//slash branch2-served:256a2cb64fd8ada4ff18d57606d212f094cb50fb o double//slash c0155e8ec55a is public, so it's correct to be in "base" and "immutable" repo views. 256a2cb64fd8 is draft (without topic), so it's expected to be in the "served" view.

=========================================
Testing single head enforcement: Case A-4
=========================================

A repository is set to only accept a single head per name (typically named
branch). However, obsolete changesets can make this enforcement more
complicated, because they can be kept visible by other changeset on other
branch.

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

Category A: Involving obsolescence
TestCase 4: Partial rewrite of a branch to dis-interleave it

.. old-state:
..
.. * 2 changesets on branch default
.. * 2 changesets on branch double//slash interleaved with the other one
..
.. new-state:
..
.. * 2 changesets on branch double//slash at the same location
.. * 1 changeset on default untouched (the lower one)
.. * 1 changeset on default moved on the other one
..
.. expected-result:
..
.. * only one head detected

Test setup
----------

  $ mkdir A4
  $ cd A4
  $ setuprepos single-head
  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 branch double//slash
  marked working directory as branch double//slash
  (branches are permanent and global, did you want a bookmark?)
  $ mkcommit B0
  $ hg branch default --force
  marked working directory as branch default
  $ mkcommit C0
  created new head
  (consider using topic for lightweight branches. See 'hg help topic')
  $ hg branch double//slash --force
  marked working directory as branch double//slash
  $ mkcommit D0
  created new head
  (consider using topic for lightweight branches. See 'hg help topic')
  $ hg push --new-branch
  pushing to $TESTTMP/A4/server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 3 changesets with 3 changes to 3 files
  $ hg up 'desc("A0")'
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ mkcommit C1
  created new head
  (consider using topic for lightweight branches. See 'hg help topic')
  $ hg debugobsolete `getid "desc(C0)"` `getid "desc(C1)"`
  1 new obsolescence markers
  obsoleted 1 changesets
  1 new orphan changesets
  $ hg log -G --hidden

Actual testing
--------------

(force push to make sure we get the changeset on the remote)

  $ hg push -r 'desc("C1")' --force
  pushing to $TESTTMP/A4/server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)
  1 new obsolescence markers
  obsoleted 1 changesets
  1 new orphan changesets
