Ensure hidden revision does not prevent histedit
-------------------------------------------------

create an hidden revision

  $ hg histedit 6 --commands - << EOF

  > drop 59d9f330561f 7 d
  > pick cacdfd884a93 8 f

  $ hg histedit 6 --commands - << EOF

Test that rewriting leaving instability behind is allowed

  $ hg log -r 'children(.)'

  $ hg rebase  -r 'unstable()' -d .
  rebasing 11:c13eb81022ca "f"

Test dropping of changeset on the top of the stack
-------------------------------------------------------

Nothing is rewritten below, the working directory parent must be change for the
dropped changeset to be hidden.

  $ cd ..
  $ hg clone base droplast
  updating to branch default
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd droplast
  $ hg histedit -r '40db8afa467b' --commands - << EOF

  > drop 947ece25170f 11 f

  $ hg log -G

  $ echo e > e
  $ hg add e
  $ hg commit -m g
  $ echo f > f
  $ hg add f
  $ hg commit -m h
  $ hg histedit -r '40db8afa467b' --commands - << EOF

Test phases support
===========================================

Check that histedit respect immutability
-------------------------------------------

  $ cat >> $HGRCPATH << EOF
  > [ui]
  > logtemplate= {rev}:{node|short} ({phase}) {desc|firstline}\n
  > EOF

  $ hg ph -pv '.^'
  phase changed for 2 changesets
  $ hg log -G

  |
  o  12:40db8afa467b (public) c
  |
  o  0:cb9a9f314b8b (public) a
  
  $ hg histedit -r '.~2'
  abort: cannot edit public changeset: cb9a9f314b8b
  (see "hg help phases" for details)
  [255]

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

  $ for x in g h i j k ; do
  >     echo $x > $x
  >     hg add $x

  $ hg phase --force --secret .~2

simple phase conservation
-------------------------------------------

Resulting changeset should conserve the phase of the original one whatever the
phases.new-commit option is.

New-commit as draft (default)

  $ cp -r base simple-draft
  $ cd simple-draft
  $ hg histedit -r '947ece25170f' --commands - << EOF
  > edit 947ece25170f 11 f
  > pick d22905de3528 12 g
  > pick ee4a24fc4dfa 13 h
  > pick 9cd3934e05af 14 i
  > pick c62e7241a4f2 15 j
  > pick 14bda137d5b3 16 k
  > EOF
  0 files updated, 0 files merged, 6 files removed, 0 files unresolved

Changeset reordering
-------------------------------------------

If a secret changeset is put before a draft one, all descendant should be secret.
It seems more important to present the secret phase.

  $ cp -r base reorder
  $ cd reorder
  $ hg histedit -r '947ece25170f' --commands - << EOF
  > pick 947ece25170f 11 f
  > pick c62e7241a4f2 15 j
  > pick d22905de3528 12 g
  > pick 9cd3934e05af 14 i
  > pick ee4a24fc4dfa 13 h
  > pick 14bda137d5b3 16 k
  > EOF
  0 files updated, 0 files merged, 5 files removed, 0 files unresolved
  $ hg log -G
  @  23:9e712162b2c1 (secret) k
  |
  o  22:490861543602 (secret) h
  |

  $ cd ..

Changeset folding
-------------------------------------------

Folding a secret changeset with a draft one turn the result secret (again,
better safe than sorry). Folding between same phase changeset still works

Note that there is a few reordering in this series for more extensive test

  $ cp -r base folding
  $ cd folding
  $ cat >> .hg/hgrc << EOF

  $ hg histedit -r '947ece25170f' --commands - << EOF

  > pick d22905de3528 12 g
  > fold c62e7241a4f2 15 j
  > pick 9cd3934e05af 14 i
