Create a repo with some stuff in it:

  $ hg init a
  $ cd a
  $ echo a > a
  $ echo a > d
  $ echo a > e
  $ hg ci -qAm0
  $ echo b > a
  $ hg ci -m1 -u bar
  $ hg mv a b
  $ hg ci -m2
  $ hg cp b c
  $ hg ci -m3 -u baz
  $ echo b > d
  $ echo f > e
  $ hg ci -m4
  $ hg up -q 3
  $ echo b > e
  $ hg branch -q stable
  $ hg ci -m5
  $ hg merge -q default --tool internal:local # for conflicts in e, choose 5 and ignore 4
  $ hg branch -q default
  $ hg ci -m6
  $ hg phase --public 3
  $ hg phase --force --secret 6

  $ hg log -G --template '{author}@{rev}.{phase}: {desc}\n'

Test --base for grafting the merge of 4 from the perspective of 5, thus only getting the change to d

  $ hg up -cqr 3
  $ hg graft -r 6 --base 5
  grafting 6:25a2b029d3ae "6" (tip)
  merging e
  $ hg st --change .
  M d

  $ hg -q strip . --config extensions.strip=

Test --base for collapsing changesets 2 and 3, thus getting both b and c

  $ hg up -cqr 0
  $ hg graft -r 3 --base 1
  grafting 3:4c60f11aa304 "3"
  merging a and b to b
  merging a and c to c
  $ hg st --change .
  A b
  A c
  R a

  $ hg -q strip . --config extensions.strip=

Specifying child as --base revision fails safely (perhaps slightly confusing, but consistent)

  $ hg graft -r 2 --base 3
  grafting 2:5c095ad7e90f "2"
  note: graft of 2:5c095ad7e90f created no changes to commit

Can't continue without starting:

  $ hg -q up -cr tip
  $ hg rm -q e
  $ hg graft --continue
  abort: no graft in progress
  [255]
  $ hg revert -r . -q e

Need to specify a rev:

  $ hg graft
  abort: no revisions specified
  [255]

Can't graft ancestor:

  $ hg graft 1 2
  skipping ancestor revision 1:5d205f8b35b6
  skipping ancestor revision 2:5c095ad7e90f
  [255]

Specify revisions with -r:

  $ hg graft -r 1 -r 2
  skipping ancestor revision 1:5d205f8b35b6
  skipping ancestor revision 2:5c095ad7e90f
  [255]

  $ hg graft -r 1 2
  warning: inconsistent use of --rev might give unexpected revision ordering!
  skipping ancestor revision 2:5c095ad7e90f
  skipping ancestor revision 1:5d205f8b35b6

Can't graft with dirty wd:

  $ hg up -q 0
  $ echo foo > a
  $ hg graft 1
  abort: uncommitted changes
  [255]
  $ hg revert a

Graft a rename:
(this also tests that editor is invoked if '--edit' is specified)

  $ hg status --rev "2^1" --rev 2
  A b
  R a
  $ HGEDITOR=cat hg graft 2 -u foo --edit
  grafting 2:5c095ad7e90f "2"

Commit while interrupted should fail:

  $ hg ci -m 'commit interrupted graft'

Graft from behind a move or rename
==================================

NOTE: This is affected by issue5343, and will need updating when it's fixed

Possible cases during a regular graft (when ca is between cta and c2):

name | c1<-cta | cta<->ca | ca->c2
A.0  |         |          |
A.1  |    X    |          |
A.2  |         |     X    |
A.3  |         |          |   X
A.4  |    X    |     X    |
A.5  |    X    |          |   X
A.6  |         |     X    |   X
A.7  |    X    |     X    |   X

A.0 is trivial, and doesn't need copy tracking.
For A.1, a forward rename is recorded in the c1 pass, to be followed later.
In A.2, the rename is recorded in the c2 pass and followed backwards.
A.3 is recorded in the c2 pass as a forward rename to be duplicated on target.
In A.4, both passes of checkcopies record incomplete renames, which are
then joined in mergecopies to record a rename to be followed.
In A.5 and A.7, the c1 pass records an incomplete rename, while the c2 pass
records an incomplete divergence. The incomplete rename is then joined to the
appropriate side of the incomplete divergence, and the result is recorded as a
divergence. The code doesn't distinguish at all between these two cases, since
the end result of them is the same: an incomplete divergence joined with an
incomplete rename into a divergence.
Finally, A.6 records a divergence entirely in the c2 pass.

A.4 has a degenerate case a<-b<-a->a, where checkcopies isn't needed at all.
A.5 has a special case a<-b<-b->a, which is treated like a<-b->a in a merge.
A.6 has a special case a<-a<-b->a. Here, checkcopies will find a spurious
incomplete divergence, which is in fact complete. This is handled later in
mergecopies.
A.7 has 4 special cases: a<-b<-a->b (the "ping-pong" case), a<-b<-c->b,
a<-b<-a->c and a<-b<-c->a. Of these, only the "ping-pong" case is interesting,
the others are fairly trivial (a<-b<-c->b and a<-b<-a->c proceed like the base
case, a<-b<-c->a is treated the same as a<-b<-b->a).

f5a therefore tests the "ping-pong" rename case, where a file is renamed to the
same name on both branches, then the rename is backed out on one branch, and
the backout is grafted to the other branch. This creates a challenging rename
sequence of a<-b<-a->b in the graft target, topological CA, graft CA and graft
source, respectively. Since rename detection will run on the c1 side for such a
sequence (as for technical reasons, we split the c1 and c2 sides not at the
graft CA, but rather at the topological CA), it will pick up a false rename,
and cause a spurious merge conflict. This false rename is always exactly the
reverse of the true rename that would be detected on the c2 side, so we can
correct for it by detecting this condition and reversing as necessary.

First, set up the repository with commits to be grafted

  $ hg init ../graftmove
  $ cd ../graftmove
  $ echo c1a > f1a
  $ echo c2a > f2a

  $ hg ci -qAm C0
  $ hg mv f3b f3d

Check superfluous filemerge of files renamed in the past but untouched by graft

  $ echo a > a
  $ hg ci -qAma
  $ hg mv a b

  $ hg ci -qAmb

  $ hg ci -qAmc

Graft a change into a new file previously grafted into a renamed directory

  $ hg init dirmovenewfile
  $ cd dirmovenewfile
  $ mkdir a
  $ echo a > a/a
  $ hg ci -qAma
  $ echo x > a/x
  $ hg ci -qAmx
  $ hg up -q 0
  $ hg mv -q a b
  $ hg ci -qAmb
  $ hg graft -q 1 # a/x grafted as b/x, but no copy information recorded
  $ hg up -q 1
  $ echo y > a/x
  $ hg ci -qAmy
  $ hg up -q 3
  $ hg graft -q 4
  $ hg status --change .
  M b/x

Prepare for test of skipped changesets and how merges can influence it:

  $ hg merge -q -r 1 --tool :local
  $ hg ci -m m
  $ echo xx >> b/x
  $ hg ci -m xx

  $ hg log -G -T '{rev} {desc|firstline}'

Grafting of plain changes correctly detects that 3 and 5 should be skipped:

  $ hg up -qCr 4
  $ hg graft --tool :local -r 2::5
  skipping already grafted revision 3:ca093ca2f1d9 (was grafted from 1:13ec5badbf2a)
  skipping already grafted revision 5:43e9eb70dab0 (was grafted from 4:6c9a1289e5f1)
  grafting 2:42127f193bcd "b"

Extending the graft range to include a (skipped) merge of 3 will not prevent us from
also detecting that both 3 and 5 should be skipped:

  $ hg up -qCr 4
  $ hg graft --tool :local -r 2::7
  skipping ungraftable merge revision 6
  skipping already grafted revision 3:ca093ca2f1d9 (was grafted from 1:13ec5badbf2a)
  skipping already grafted revision 5:43e9eb70dab0 (was grafted from 4:6c9a1289e5f1)
  grafting 2:42127f193bcd "b"
  grafting 7:d3c3f2b38ecc "xx"
  note: graft of 7:d3c3f2b38ecc created no changes to commit

  $ cd ..

Grafted revision should be warned and skipped only once. (issue6024)

  $ mkdir issue6024
  $ cd issue6024

  $ hg init base
  $ cd base
  $ touch x
