initial setup
$ mkdir base
$ cd base
$ hg init server
$ cd server
$ mkcommit root
$ hg phase --public .
$ mkcommit commit_A0_
$ mkcommit commit_B0_
$ cd ..
$ hg init client

$ echo '[paths]' >> .hg/hgrc
$ echo 'default=../server' >> .hg/hgrc
$ hg pull
pulling from $TESTTMP/base/server
requesting all changes
adding changesets
adding manifests
adding file changes
added 3 changesets with 3 changes to 3 files
new changesets 1e4be0697311:c09d8ab29fda (2 drafts)
(run 'hg update' to get a working copy)
$ hg up 'desc("root")'
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(having some unrelated change affects discovery result, we should ideally test both case)
$ hg branch unrelated --quiet
$ mkcommit unrelated
$ hg up null
0 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ hg log -G

searching for changes
no changes found
1 new obsolescence markers
