TODO: configure mutation
  $ configure noevolution
  $ enable conflictinfo rebase

1) Make the repo
  $ mkdir basic
  $ cd basic
  $ hg init

2) Can't run dumpjson outside a conflict
  $ hg resolve --tool internal:dumpjson
  abort: no files or directories specified
  (use --all to re-merge all unresolved files)
  [255]

3) Make a simple conflict
  $ echo "Unconflicted base, F1" > F1
  $ echo "Unconflicted base, F2" > F2
  $ hg commit -Aqm "initial commit"
  $ echo "First conflicted version, F1" > F1
  $ echo "First conflicted version, F2" > F2
  $ hg commit -m "first version, a"
  $ hg bookmark a
  $ hg checkout .~1
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (leaving bookmark a)
  $ echo "Second conflicted version, F1" > F1
  $ echo "Second conflicted version, F2" > F2
  $ hg commit -m "second version, b"
  $ hg bookmark b
  $ hg log -G -T '({rev}) {desc}\nbookmark: {bookmarks}\nfiles: {files}\n\n'
  @  (2) second version, b
  |  bookmark: b
  |  files: F1 F2
  |
  | o  (1) first version, a
  |/   bookmark: a
  |    files: F1 F2
  |
  o  (0) initial commit
     bookmark:
     files: F1 F2
  
  $ hg merge a
  merging F1
  merging F2
  warning: 1 conflicts while merging F1! (edit, then use 'hg resolve --mark')
  warning: 1 conflicts while merging F2! (edit, then use 'hg resolve --mark')
  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]

5) Get the paths:
  $ hg resolve --tool internal:dumpjson --all
  [
   {
    "command": "merge",
    "command_details": {"cmd": "merge", "to_abort": "update --clean", "to_continue": "merge --continue"},
    "conflicts": [{"base": {"contents": "Unconflicted base, F1\n", "exists": true, "isexec": false, "issymlink": false}, "local": {"contents": "Second conflicted version, F1\n", "exists": true, "isexec": false, "issymlink": false}, "other": {"contents": "First conflicted version, F1\n", "exists": true, "isexec": false, "issymlink": false}, "output": {"contents": "<<<<<<< working copy: 13124abb51b9 b - test: second version, b\nSecond conflicted version, F1\n=======\nFirst conflicted version, F1\n>>>>>>> merge rev:    6dd692b7db4a a - test: first version, a\n", "exists": true, "isexec": false, "issymlink": false, "path": "$TESTTMP/basic/F1"}, "path": "F1"}, {"base": {"contents": "Unconflicted base, F2\n", "exists": true, "isexec": false, "issymlink": false}, "local": {"contents": "Second conflicted version, F2\n", "exists": true, "isexec": false, "issymlink": false}, "other": {"contents": "First conflicted version, F2\n", "exists": true, "isexec": false, "issymlink": false}, "output": {"contents": "<<<<<<< working copy: 13124abb51b9 b - test: second version, b\nSecond conflicted version, F2\n=======\nFirst conflicted version, F2\n>>>>>>> merge rev:    6dd692b7db4a a - test: first version, a\n", "exists": true, "isexec": false, "issymlink": false, "path": "$TESTTMP/basic/F2"}, "path": "F2"}],
    "pathconflicts": []
   }
  ]

6) Only requested paths get dumped
  $ hg resolve --tool internal:dumpjson F2
  [
   {
    "command": "merge",
    "command_details": {"cmd": "merge", "to_abort": "update --clean", "to_continue": "merge --continue"},
    "conflicts": [{"base": {"contents": "Unconflicted base, F2\n", "exists": true, "isexec": false, "issymlink": false}, "local": {"contents": "Second conflicted version, F2\n", "exists": true, "isexec": false, "issymlink": false}, "other": {"contents": "First conflicted version, F2\n", "exists": true, "isexec": false, "issymlink": false}, "output": {"contents": "<<<<<<< working copy: 13124abb51b9 b - test: second version, b\nSecond conflicted version, F2\n=======\nFirst conflicted version, F2\n>>>>>>> merge rev:    6dd692b7db4a a - test: first version, a\n", "exists": true, "isexec": false, "issymlink": false, "path": "$TESTTMP/basic/F2"}, "path": "F2"}],
    "pathconflicts": []
   }
  ]

7) Ensure the paths point to the right contents:
  $ getcontents() { # Usage: getcontents <path> <version>
  >  local script="import sys, json; print(json.load(sys.stdin)[0][\"conflicts\"][$1][\"$2\"][\"contents\"])"
  >  local result=`hg resolve --tool internal:dumpjson --all | python -c "$script"`
  >  echo "$result"
  > }
  $ echo `getcontents 0 "base"`
  Unconflicted base, F1
  $ echo `getcontents 0 "other"`
  First conflicted version, F1
  $ echo `getcontents 0 "local"`
  Second conflicted version, F1
  $ echo `getcontents 1 "base"`
  Unconflicted base, F2
  $ echo `getcontents 1 "other"`
  First conflicted version, F2
  $ echo `getcontents 1 "local"`
  Second conflicted version, F2

Tests merge conflict corner cases (file-to-directory, binary-to-symlink, etc.)
"other" == source
"local" == dest

Setup
  $ cd ..
  $ rm -rf basic
  $ mkdir cornercases
  $ cd cornercases

  $ reset() {
  >   rm -rf foo
  >   mkdir foo
  >   cd foo
  >   hg init
  >   echo "base" > file
  >   hg commit -Aqm "base"
  > }
  $ logg() {
  >   hg log -G -T '({rev}) {desc}\naffected: {files}\ndeleted: {file_dels}\n\n'
  > }

Test case 0: A merge of just contents conflicts (not usually a corner case),
but the user had local changes and ran `merge -f`.

tldr: Since we can premerge, the working copy is backed up to an origfile.

command_details works correctly with commands that drop both a statefile and a
mergestate (like shelve):
  $ hg init command_details
  $ cd command_details
  $ cat >> .hg/hgrc <<EOF
  > [extensions]
  > shelve=
  > [experimental]
  > evolution = createmarkers
  > EOF
  $ hg debugdrawdag <<'EOS'
  > b c
  > |/
  > a
  > EOS
  $ hg up -q c
  $ echo 'state' > b
  $ hg add -q
  $ hg shelve
  shelved as c
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg up -q b
  $ hg unshelve
  unshelving change 'c'
  rebasing shelved changes
