Build some basic graph
----------------------
$ for x in base_a base_b base_c base_d base_e ; do
> mkcommit $x
> done
Add another branch with two heads
$ hg up 'desc(base_a)'
0 files updated, 0 files merged, 4 files removed, 0 files unresolved
$ hg branch lake
marked working directory as branch lake
(branches are permanent and global, did you want a bookmark?)
$ mkcommit lake_a
$ mkcommit lake_b
$ hg up 'desc(lake_a)'
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ mkcommit lake_c
created new head
(consider using topic for lightweight branches. See 'hg help topic')
Add some topics
---------------
A simple topic that need rebasing
$ hg up 'desc(base_c)'
2 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ hg topic baz
marked working directory as topic: baz
$ mkcommit baz_a
active topic 'baz' grew its first changeset
(see 'hg help topics' for more information)
$ mkcommit baz_b
A simple topic with instability
$ hg up 'desc(base_d)'
1 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ hg topic fuz
marked working directory as topic: fuz
$ mkcommit fuz_a
active topic 'fuz' grew its first changeset
(see 'hg help topics' for more information)
$ mkcommit fuz_b
$ mkcommit fuz_c
$ hg up 'desc(fuz_a)'
0 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ hg commit --amend --message 'fuz1_a'
2 new orphan changesets
A topic with multiple heads
$ hg up 'desc(base_e)'
1 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg topic bar
marked working directory as topic: bar
$ mkcommit bar_a
active topic 'bar' grew its first changeset
(see 'hg help topics' for more information)
$ mkcommit bar_b
$ mkcommit bar_c
$ hg up 'desc(bar_b)'
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ mkcommit bar_d
$ mkcommit bar_e
$ hg up 'desc(bar_d)'
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg commit --amend --message 'bar1_d'
1 new orphan changesets
topic 'foo' on the multi headed branch
$ hg up 'desc(lake_a)'
1 files updated, 0 files merged, 7 files removed, 0 files unresolved
$ hg topic foo
marked working directory as topic: foo
$ mkcommit foo_a
active topic 'foo' grew its first changeset
(see 'hg help topics' for more information)
$ mkcommit foo_b
