Set up server repository

  $ cd server
  $ mkcommit initial
  $ mkcommit secondcommit
  $ hg book master
  $ cd ..

Set up clients repository

  $ hg clone ssh://user@dummy/server client -q
  $ hg clone ssh://user@dummy/server otherclient -q

The first client works on several diffs while the second client lands one of her diff

  $ cd otherclient
  $ mkcommit b
  $ hg push --to master
  pushing rev 2e73b79a63d8 to destination ssh://user@dummy/server bookmark master
  searching for changes
  remote: pushing 1 changeset:
  remote:     2e73b79a63d8  add b
  updating bookmark master
  $ cd ../client
  $ mkcommit c 123 # 123 is the phabricator rev number (see function above)
  $ mkcommit d 124 "https://phabricator.intern.facebook.com"
  $ mkcommit e 131
  $ hg log -G -T '{rev} "{desc}" {remotebookmarks}'

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  obsoleted 3 changesets

Here we strip commits 6, 7, 8 to simulate what happens with landcastle, the
push doesn't directly go to the server

  $ hg debugstrip 6
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  saved backup bundle to $TESTTMP/client/.hg/strip-backup/d446b1b2be43-516f7371-backup.hg (glob)

We update to commit 1 to avoid keeping 2, 3, and 4 visible with inhibit

  $ hg update 1
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

Here pull should mark 2, 3, and 4 as obsolete since they landed as 6, 7, 8 on
the remote
  $ hg log -G -T '{rev} "{desc}" {remotebookmarks}'

Rebasing a stack containing landed changesets should only rebase the non-landed
changesets

  $ hg up --hidden 4 # --hidden because directaccess works only with hashes
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ mkcommit k 202
  $ hg rebase -d default/master
  note: not rebasing 1a07332e9fa1 "add c", already in destination as d446b1b2be43 "add c"
  note: not rebasing ee96b78ae17d "add d", already in destination as 1f539cc6f364 "add d"
  note: not rebasing d5895ab36037 "add e", already in destination as 461a5b25b3dc "add e" (default/master master)

  $ echo more >> k
  $ hg amend
  $ hg unhide 10

  $ cd ../server
  $ mkcommit k 202
  $ cd ../client
  $ hg pull

(Note: pullcreatemarkers created two markers, however only one of them was
counted in the message as the first commit had previously been obsoleted
and revived)
