Disable default date on commit so when -d isn't given, the old date is preserved:

  $ echo '[defaults]' >> $HGRCPATH
  $ echo 'commit=' >> $HGRCPATH

Test -u/-d:

  $ hg ci --amend -u foo -d '1 0'

Moving bookmarks, preserve active bookmark:

  $ hg book book1
  $ hg book book2
  $ hg ci --amend -m 'move bookmarks'
  saved backup bundle to $TESTTMP/.hg/strip-backup/fb6cca43446f-amend-backup.hg
  $ hg book

  $ echo a >> a
  $ hg ci --amend -m 'move bookmarks'
  saved backup bundle to $TESTTMP/.hg/strip-backup/0cf1c7a51bcf-amend-backup.hg
  $ hg book
     book1                     1:7344472bd951
   * book2                     1:7344472bd951

  $ 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/1661ca36a2db-amend-backup.hg
  $ hg branches
  default                        2:f24ee5961967

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

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/5e302dcc12b8-amend-backup.hg
  $ hg branches
  default                        2:f24ee5961967

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/9c207120aa98-amend-backup.hg
  $ 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/fda2b3b27b22-amend-backup.hg
  $ 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/20a7413547f9-amend-backup.hg
  $ 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/5daa77a5d616-amend-backup.hg
  $ 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/167f8e3031df-amend-backup.hg
  $ hg log -r . --template "{branch}\n"
  a
  $ hg ci --amend -m "a''"
  saved backup bundle to $TESTTMP/.hg/strip-backup/ceac1a44c806-amend-backup.hg
  $ 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/18a5124daf7a-amend-backup.hg
  $ hg log -r . --debug | grep extra
  extra:       branch=a
  extra:       source=2647734878ef0236dda712fae9c1651cf694ea8a
