Rebasing

D onto H - simple rebase:

  $ hg clone -q -u . a a1

  $ cd a1

  $ hg tglog

  @  7: 'H'

  | o  6: 'G'

  |/|

  $ hg rebase -s 3 -d 7

  $ hg tglog

  o  0: 'A'

  $ cd ..

D onto F - intermediate point:

  $ hg clone -q -u . a a2

  $ cd a2

  $ hg rebase -s 3 -d 5

  saved backup bundle to $TESTTMP/a2/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog

  | |

  |/

  o  0: 'A'

  $ cd ..

E onto H - skip of G:

  $ hg clone -q -u . a a3

  $ cd a3

  $ hg rebase -s 4 -d 7

  saved backup bundle to $TESTTMP/a3/.hg/strip-backup/*-backup.hg (glob)

F onto E - rebase of a branching point (skip G):

  $ hg clone -q -u . a a4

  $ cd a4

  $ hg rebase -s 5 -d 4

  saved backup bundle to $TESTTMP/a4/.hg/strip-backup/*-backup.hg (glob)

G onto H - merged revision having a parent in ancestors of target:

  $ hg clone -q -u . a a5

  $ cd a5

  $ hg rebase -s 6 -d 7

  saved backup bundle to $TESTTMP/a5/.hg/strip-backup/*-backup.hg (glob)

  o  0: 'A'

  $ cd ..

F onto B - G maintains E as parent:

  $ hg clone -q -u . a a6

  $ cd a6

  $ hg rebase -s 5 -d 1

  saved backup bundle to $TESTTMP/a6/.hg/strip-backup/*-backup.hg (glob)

  $ cd ..

These will fail (using --source):

G onto F - rebase onto an ancestor:

  $ hg clone -q -u . a a7

  $ cd a7

  $ hg rebase -s 6 -d 5

  nothing to rebase

  [1]

F onto G - rebase onto a descendant:

  $ hg rebase -s 5 -d 6

  abort: source is ancestor of destination

  [255]

G onto B - merge revision with both parents not in ancestors of target:

  $ hg rebase -s 6 -d 1

  abort: cannot use revision 6 as base, result would have 3 parents

  [255]

These will abort gracefully (using --base):

G onto G - rebase onto same changeset:

  $ hg rebase -b 6 -d 6

  nothing to rebase

  [1]

G onto F - rebase onto an ancestor:

  $ hg rebase -b 6 -d 5

  nothing to rebase

  [1]

F onto G - rebase onto a descendant:

  $ hg rebase -b 5 -d 6

  nothing to rebase

  [1]

C onto A - rebase onto an ancestor:

  $ hg rebase -d 0 -s 2

  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/5fddd98957c8-backup.hg (glob)

Check rebasing public changeset

  $ hg pull --config phases.publish=True -q -r 6 . # update phase of 6

  $ hg rebase -d 5 -b 6

  abort: can't rebase immutable changeset e1c4361dd923

  (see hg help phases for details)

  [255]

  $ hg rebase -d 5 -b 6 --keep

Check rebasing mutable changeset

Source phase greater or equal to destination phase: new changeset get the phase of source:

  $ hg rebase -s9 -d0

  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/2b23e52411f4-backup.hg (glob)

  $ hg log --template "{phase}\n" -r 9

  draft

  $ hg rebase -s9 -d1

  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/2cb10d0cfc6c-backup.hg (glob)

  $ hg log --template "{phase}\n" -r 9

  draft

  $ hg phase --force --secret 9

  $ hg rebase -s9 -d0

  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/c5b12b67163a-backup.hg (glob)

  $ hg log --template "{phase}\n" -r 9

  secret

  $ hg rebase -s9 -d1

  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/2a0524f868ac-backup.hg (glob)

  $ hg log --template "{phase}\n" -r 9

  secret

Source phase lower than destination phase: new changeset get the phase of destination:

  secret

  $ cd ..

Test for revset

We need a bit different graph

All destination are B

  $ hg init ah

  $ cd ah

  $ hg unbundle "$TESTDIR/bundles/rebase-revset.hg"

  adding changesets

  adding manifests

  adding file changes

  added 9 changesets with 9 changes to 9 files (+2 heads)

  $ hg tglog

  $ cd ..

Simple case with keep:

Source on have two descendant heads but ask for one

  $ hg clone -q -u . ah ah1

  $ cd ah1

  $ hg rebase -r '2::8' -d 1

  abort: can't remove original changesets with unrebased descendants

  (use --keep to keep original changesets)

  [255]

  $ hg rebase -r '2::8' -d 1 --keep

  $ hg tglog

  @  13: 'I'

  o  12: 'H'

  |

  o  11: 'G'

  o  10: 'D'

  o  9: 'C'

  | o  2: 'C'

  o |  1: 'B'

  o  0: 'A'

  $ cd ..

Base on have one descendant heads we ask for but common ancestor have two

  $ hg clone -q -u . ah ah2

  $ cd ah2

  $ hg rebase -r '3::8' -d 1

  abort: can't remove original changesets with unrebased descendants

  (use --keep to keep original changesets)

  [255]

  $ hg rebase -r '3::8' -d 1 --keep

  $ hg tglog
