Basic tests
===========
(no criss cross merge)

Smoke tests
-----------

Starts with a "simple case"

  $ hg init repo_A
  $ cd repo_A
  $ hg debugbuilddag '
  > ..:g   # 2 nodes, tagged "g"
  > <2.:h   # another node base one -2 -> 0, tagged "h"
  > *1/2:m # merge -1 and -2 (1, 2), tagged "m"
  > <2+2:i # 2 nodes based on -2, tag head as "i"
  > .:c    # 1 node tagged "c"
  > <m+3:a # 3 nodes base on the "m" tag
  > <2.:b  # 1 node based on -2; tagged "b"
  > <m+2:d # 2 nodes from "m" tagged "d"
  > <2.:e  # 1 node based on -2, tagged "e"
  > <m+1:f # 1 node based on "m" tagged "f"
  > <i/f   # merge "i" and "f"

Test behavior with oedipus merges
=================================

  $ hg init recursion_oedipus
  $ cd recursion_oedipus
  $ echo base > base
  $ hg add base
  $ hg ci -m base
  $ hg branch foo
  marked working directory as branch foo
  (branches are permanent and global, did you want a bookmark?)
  $ echo foo1 > foo1
  $ hg add foo1
  $ hg ci -m foo1
  $ echo foo2 > foo2
  $ hg add foo2
  $ hg ci -m foo2
  $ hg up default
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg merge foo
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m oedipus_merge
  $ echo default1 > default1
  $ hg add default1
  $ hg ci -m default1
  $ hg log -G
