Moving bookmarks, preserve active bookmark:

   * book2                     1:48bb6e53a15f

  $ echo '[defaults]' >> $HGRCPATH
  $ echo "commit=-d '0 0'" >> $HGRCPATH

Moving branches:

  $ hg branch foo
  marked working directory as branch foo
  (branches are permanent and global, did you want a bookmark?)
  $ echo a >> a
  $ hg ci -m 'branch foo'
  $ hg branch default -f
  marked working directory as branch default
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci --amend -m 'back to default'
  saved backup bundle to $TESTTMP/.hg/strip-backup/8ac881fbf49d-amend-backup.hg (glob)
  $ hg branches
  default                        2:ce12b0b57d46

Close branch:

  $ hg up -q 0
  $ echo b >> b
  $ hg branch foo
  marked working directory as branch foo
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -Am 'fork'
  adding b
  $ echo b >> b
  $ hg ci -mb
  $ hg ci --amend --close-branch -m 'closing branch foo'
  saved backup bundle to $TESTTMP/.hg/strip-backup/c962248fa264-amend-backup.hg (glob)

Same thing, different code path:

  $ echo b >> b
  $ hg ci -m 'reopen branch'
  reopening closed branch head 4
  $ echo b >> b
  $ hg ci --amend --close-branch
  saved backup bundle to $TESTTMP/.hg/strip-backup/027371728205-amend-backup.hg (glob)
  $ hg branches
  default                        2:ce12b0b57d46

Refuse to amend merges:

  $ hg up -q default
  $ hg merge foo
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci --amend
  abort: cannot amend while merging
  [255]
  $ hg ci -m 'merge'
  $ hg ci --amend
  abort: cannot amend merge changesets
  [255]

Follow copies/renames:

  $ hg mv b c
  $ hg ci -m 'b -> c'
  $ hg mv c d
  $ hg ci --amend -m 'b -> d'
  saved backup bundle to $TESTTMP/.hg/strip-backup/b8c6eac7f12e-amend-backup.hg (glob)
  $ hg st --rev '.^' --copies d
  A d
    b
  $ hg cp d e
  $ hg ci -m 'e = d'
  $ hg cp e f
  $ hg ci --amend -m 'f = d'
  saved backup bundle to $TESTTMP/.hg/strip-backup/7f9761d65613-amend-backup.hg (glob)
  $ hg st --rev '.^' --copies f
  A f
    d

  $ mv f f.orig
  $ hg rm -A f
  $ hg ci -m removef
  $ hg cp a f
  $ mv f.orig f
  $ hg ci --amend -m replacef
  saved backup bundle to $TESTTMP/.hg/strip-backup/9e8c5f7e3d95-amend-backup.hg (glob)
  $ hg st --change . --copies
  $ hg log -r . --template "{file_copies}\n"
  

Move added file (issue3410):

  $ echo g >> g
  $ hg ci -Am g
  adding g
  $ hg mv g h
  $ hg ci --amend
  saved backup bundle to $TESTTMP/.hg/strip-backup/24aa8eacce2b-amend-backup.hg (glob)
  $ hg st --change . --copies h
  A h
  $ hg log -r . --template "{file_copies}\n"
  

Can't rollback an amend:

  $ hg rollback
  no rollback information available
  [1]

Preserve extra dict (issue3430):

  $ hg branch a
  marked working directory as branch a
  (branches are permanent and global, did you want a bookmark?)
  $ echo a >> a
  $ hg ci -ma
  $ hg ci --amend -m "a'"
  saved backup bundle to $TESTTMP/.hg/strip-backup/3837aa2a2fdb-amend-backup.hg (glob)
  $ hg log -r . --template "{branch}\n"
  a
  $ hg ci --amend -m "a''"
  saved backup bundle to $TESTTMP/.hg/strip-backup/c05c06be7514-amend-backup.hg (glob)
  $ hg log -r . --template "{branch}\n"
  a

Also preserve other entries in the dict that are in the old commit,
first graft something so there's an additional entry:

  $ hg up 0 -q
  $ echo z > z
  $ hg ci -Am 'fork'
  adding z
  created new head
  $ hg up 11
  5 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg graft 12
  grafting revision 12
  $ hg ci --amend -m 'graft amend'
  saved backup bundle to $TESTTMP/.hg/strip-backup/bd010aea3f39-amend-backup.hg (glob)
  $ hg log -r . --debug | grep extra
  extra:       amend_source=bd010aea3f39f3fb2a2f884b9ccb0471cd77398e
  extra:       branch=a
  extra:       source=2647734878ef0236dda712fae9c1651cf694ea8a

Preserve phase

  $ hg phase '.^::.'
  11: draft
  13: draft
  $ hg phase --secret --force .
  $ hg phase '.^::.'
  11: draft
  13: secret
  $ hg commit --amend -m 'amend for phase' -q
  $ hg phase '.^::.'
  11: draft
  13: secret

Test amend with obsolete
---------------------------

Enable obsolete

  $ cat > ${TESTTMP}/obs.py << EOF
  > import mercurial.obsolete
  > mercurial.obsolete._enabled = True
  > EOF
  $ echo '[extensions]' >> $HGRCPATH
  $ echo "obs=${TESTTMP}/obs.py" >> $HGRCPATH

ride of)
