Check that topic without any parent does not crash --list

---------------------------------------------------------

  $ hg up other

  switching to topic other

  0 files updated, 0 files merged, 4 files removed, 0 files unresolved

  $ hg topic --list

  ### topic: other

  ### target: default (branch)

  $ hg phase --public 'topic("other")'

  active topic 'other' is now empty

  (use 'hg topic --clear' to clear it if needed)

After changing the phase of all the changesets in "other" to public, the topic should still be active, but is empty. We should be better at informating the user about it and displaying good data in this case.

  $ hg topic

     foo   (4 changesets)

   * other (0 changesets)

  $ hg stack

  ### topic: other

  ### target: default (branch)

  (stack is empty)

  $ hg up foo

  switching to topic foo

  4 files updated, 0 files merged, 0 files removed, 0 files unresolved

Simple test

-----------

'hg stack' list all changeset in the topic

  $ hg topic

   * foo (4 changesets)

  $ hg stack

  ### topic: foo

  ### target: default (branch)

  $ hg stack -v

  ### topic: foo

  ### target: default (branch)

  $ hg stack -Tjson | python -m json.tool

check that topics and stack are available even if ui.strict=true

  $ hg topics

   * foo (4 changesets)

  $ hg stack

  ### topic: foo

  ### target: default (branch)

  $ hg topics --config ui.strict=true

   * foo (4 changesets)

  $ hg stack --config ui.strict=true

  ### topic: foo

  ### target: default (branch)

error case, nothing to list

  $ hg topic --clear

  $ hg stack

  ### target: default (branch)

  (stack is empty)

Test "t#" reference

-------------------

  $ hg up s2

  abort: cannot resolve "s2": branch "default" has only 0 non-public changesets

  [255]

  $ hg topic foo

  marked working directory as topic: foo

  $ hg up t42

  abort: cannot resolve "t42": topic "foo" has only 4 changesets

  [255]

  $ hg up s42

  abort: cannot resolve "s42": topic "foo" has only 4 changesets

  [255]

  $ hg up s2

  $ hg summary

Case with some of the topic unstable

------------------------------------

  $ echo bbb > ddd

  $ hg commit --amend

  2 new orphan changesets

  $ hg log -G

  $ hg topic --list

  ### topic: foo

  ### target: default (branch)

  $ hg up s3

  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg topic --list

  [topic.stack.summary.branches|### target: default (branch)]

  $ hg up s2

  1 files updated, 0 files merged, 1 files removed, 0 files unresolved

Also test the revset:

  $ hg log -r 'stack()'

  2 default {foo} draft c_c

  6 default {foo} draft c_d

  4 default {foo} draft c_e

  5 default {foo} draft c_f

  $ hg log -r 'stack(foo)'

  hg: parse error: stack() takes no argument, it works on current topic

  [255]

  $ hg log -r 'stack(foobar)'

  hg: parse error: stack() takes no argument, it works on current topic

  [255]

Case with multiple heads on the topic

-------------------------------------

Make things linear again

  $ hg rebase -s 'desc(c_e)' -d 'desc(c_d) - obsolete()'

  rebasing 4:0f9ac936c87d "c_e" (foo)

  rebasing 5:6559e6d93aea "c_f" (foo)

  $ hg log -G

  o  8 default {foo} draft c_f

  |

  o  2 default {foo} draft c_c

  |

  o  1 default {} public c_b

  o  0 default {} public c_a

Create the second branch

  $ hg up 'desc(c_d)'

  $ echo aaa > ggg

  $ hg add ggg

  $ hg commit -m c_g

  $ echo aaa > hhh

  $ hg add hhh

  $ hg commit -m c_h

  $ hg log -G
