Run a dummy edit to make sure we get tip^^ correctly via revsingle.

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

  $ HGEDITOR=cat hg histedit "tip^^"

  pick eb57da33312f 2 three

  pick c8e68270e35a 3 four

  pick 08d98a8350f3 4 five

  # Edit history between eb57da33312f and 08d98a8350f3

  #

  # Commands:

  #  p, pick = use commit

  #  e, edit = use commit, but stop for amending

  #  d, drop = remove commit from history

  #  m, mess = edit message without changing commit content

Run on a revision not ancestors of the current working directory.

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

  $ hg up 2

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

  $ hg histedit -r 4

  abort: 08d98a8350f3 is not an ancestor of working directory

  [255]

  $ hg up --quiet

Run on a revision not descendants of the initial parent

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

Test the message shown for inconsistent histedit state, which may be

created (and forgotten) by Mercurial earlier than 2.7. This emulates

Mercurial earlier than 2.7 by renaming ".hg/histedit-state"

temporarily.

  reverting alpha

  Make changes as needed, you may commit or record as needed now.

  When you are finished, run hg histedit --continue to resume.

  [1]

  $ mv .hg/histedit-state .hg/histedit-state.back

  $ hg update --quiet --clean 2

  $ mv .hg/histedit-state.back .hg/histedit-state

  $ hg histedit --continue

  abort: c8e68270e35a is not an ancestor of working directory

  (use "histedit --abort" to clear broken state)

  [255]

  $ hg histedit --abort

  $ hg update --quiet --clean

Test that missing revisions are detected

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

  $ HGEDITOR=cat hg histedit "tip^^" --commands - << EOF

  > pick eb57da33312f 2 three

  > pick 08d98a8350f3 4 five

  > EOF

  abort: missing rules for changeset c8e68270e35a

  (do you want to use the drop action?)

  [255]

Test that extra revisions are detected

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

  $ HGEDITOR=cat hg histedit "tip^^" --commands - << EOF

  > pick 6058cbb6cfd7 0 one

  > pick c8e68270e35a 3 four

  > pick 08d98a8350f3 4 five

  > EOF

  abort: may not use changesets other than the ones listed

  [255]

Test malformed line

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

  $ HGEDITOR=cat hg histedit "tip^^" --commands - << EOF

  > pickeb57da33312f2three

  > pick c8e68270e35a 3 four

  > pick 08d98a8350f3 4 five

  > EOF

  abort: malformed line "pickeb57da33312f2three"

  [255]

Test unknown changeset

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

  $ HGEDITOR=cat hg histedit "tip^^" --commands - << EOF

  > pick 0123456789ab 2 three

  > pick c8e68270e35a 3 four

  > pick 08d98a8350f3 4 five

  > EOF

  abort: unknown changeset 0123456789ab listed

  [255]

Test unknown command

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

  $ HGEDITOR=cat hg histedit "tip^^" --commands - << EOF

  > coin eb57da33312f 2 three

  > pick c8e68270e35a 3 four

  > pick 08d98a8350f3 4 five

  > EOF

  abort: unknown action "coin"

  [255]

Test duplicated changeset

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

So one is missing and one appear twice.

  $ HGEDITOR=cat hg histedit "tip^^" --commands - << EOF

  > pick eb57da33312f 2 three

  > pick eb57da33312f 2 three

  > pick 08d98a8350f3 4 five

  > EOF

  abort: duplicated command for changeset eb57da33312f

  [255]

Test short version of command

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

Note: we use varying amounts of white space between command name and changeset

short hash. This tests issue3893.

  $ HGEDITOR=cat hg histedit "tip^^" --commands - << EOF

  > pick eb57da33312f 2 three
