test that a commit clears the merge state.

  $ hg init repo

  $ cd repo

  $ echo foo > file1

  $ echo foo > file2

  $ hg commit -Am 'add files'

  adding file1

  adding file2

  $ echo bar >> file1

  $ echo bar >> file2

  $ hg commit -Am 'append bar to files'

create a second head with conflicting edits

  $ hg up -C 0

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

  $ echo baz >> file1

  $ echo baz >> file2

  $ hg commit -Am 'append baz to files'

  created new head

create a third head with no conflicting edits

  $ hg up -qC 0

  $ echo foo > file3

  $ hg commit -Am 'add non-conflicting file'

  adding file3

  created new head

failing merge

  $ hg up -qC 2

  $ hg merge --tool=internal:fail 1

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

  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon

  [1]

resolve -l should contain unresolved entries

  $ hg resolve -l

  U file1

  U file2

  $ hg resolve -l --no-status

  file1

  file2

resolving an unknown path should emit a warning, but not for -l

  $ hg resolve -m does-not-exist

  arguments do not match paths that need resolving

  $ hg resolve -l does-not-exist

resolve the failure

  $ echo resolved > file1

  $ hg resolve -m file1

resolve -l should show resolved file as resolved

  $ hg resolve -l

  R file1

  U file2

  $ hg resolve -l -Tjson

  [

   {

    "path": "file1",

    "status": "R"

   },

   {

    "path": "file2",

    "status": "U"

   }

  ]

resolve -m without paths should mark all resolved

  $ hg resolve -m

  (no more unresolved files)

  $ hg commit -m 'resolved'

resolve -l should be empty after commit

  $ hg resolve -l

  $ hg resolve -l -Tjson

  [

  ]

resolve --all should abort when no merge in progress

  $ hg resolve --all

  abort: resolve command not applicable when not merging

  [255]

resolve -m should abort when no merge in progress

  $ hg resolve -m

  abort: resolve command not applicable when not merging

set up conflict-free merge

  $ hg up -qC 3

  $ hg merge 1

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

  (branch merge, don't forget to commit)

resolve --all should do nothing in merge without conflicts

  $ hg resolve --all

  (no more unresolved files)

resolve -m should do nothing in merge without conflicts

  $ hg resolve -m

  (no more unresolved files)

get back to conflicting state

  $ hg up -qC 2

  $ hg merge --tool=internal:fail 1

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

  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon

  [1]

resolve without arguments should suggest --all

  $ hg resolve

  abort: no files or directories specified

  (use --all to re-merge all unresolved files)

  [255]

resolve --all should re-merge all unresolved files

  $ hg resolve -q --all

  [1]

  $ grep '<<<' file1 > /dev/null

  $ grep '<<<' file2 > /dev/null

resolve <file> should re-merge file

  $ echo resolved > file1

  $ hg resolve -q file1

  [1]

  $ grep '<<<' file1 > /dev/null

resolve <file> should do nothing if 'file' was marked resolved

  $ echo resolved > file1

  $ hg resolve -m file1

  $ hg resolve -q file1

  $ cat file1

  resolved

test crashed merge with empty mergestate

  $ hg up -qC 1

  $ mkdir .hg/merge

  $ touch .hg/merge/state

resolve -l should be empty

  $ hg resolve -l

  $ cd ..
