Test order of proposed commit message

  $ hg fold --exact --hidden -r 4 -r 5 -r 6
  2 new content-divergent changesets
  3 changesets folded
  $ hg log -r tip -T '{desc}'
  r4
  
  
  r5
  
  
  r6 (no-eol)
  $ hg fold --exact --hidden -r 6 -r 4 -r 5

One merge commit

  $ hg init fold-a-merge
  $ cd fold-a-merge

  $ mkcommit zebra

  $ hg up null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit apple
  $ mkcommit banana

  $ hg merge
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m merge

  $ mkcommit coconut

  $ hg glf
  @  4: coconut (coconut)
  |
  o    3: merge ()
  |\
  | o  2: banana (banana)
  | |
  | o  1: apple (apple)
  |
  o  0: zebra (zebra)
  

now we merge some of the fruits

  $ hg fold --exact -r 'desc("banana")::desc("coconut")' -m 'banana+coconut in a merge with zebra'
  3 changesets folded
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg glf
  @    5: banana+coconut in a merge with zebra (banana coconut)
  |\
  | o  1: apple (apple)
  |
  o  0: zebra (zebra)
  

let's go even further: zebra becomes a parent of the squashed fruit commit

  $ hg fold --from -r 'desc("apple")' -m 'apple+banana+coconut is a child of zebra'
  2 changesets folded
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg glf
  @  6: apple+banana+coconut is a child of zebra (apple banana coconut)
  |
  o  0: zebra (zebra)
  

make sure zebra exists at tip and has expected contents

  $ hg cat -r tip zebra
  zebra

  $ cd ..

Multiple merge commits

  $ hg init fold-many-merges
  $ cd fold-many-merges

  $ hg debugbuilddag '+3 *3 /3 /4 /4'
  $ hg glog
  o    6: r6

  o /  1: r1

  o  0: r0
  

cannot fold 5 and 6 because they have 3 external parents in total: 1, 2, 4

  $ hg fold --exact -r 5:6 -m r5+r6
  abort: cannot fold revisions that merge with more than one external changeset (not in revisions)
  [255]

now many of the parents are included in the revisions to fold, only 0 and 3 are external

  $ hg fold --exact -r 1+2+4+5+6 -m r1+r2+r4+r5+r6
  5 changesets folded

  $ hg glog
  o    7: r1+r2+r4+r5+r6
