thirdparty: remove Python 2-specific selectors2 copy The selectors module was added in Python 3.4. Because we require Python 3.6, it will always be available. Therefore the selectors2 module is not imported. I’ve verified that the selectors2-specific workaround in commandserver.py is not necessary with the selectors module from the standard library. It returns an empty list if timeout was exceeded. The pytype directive was needed to silence the following error: File "/tmp/mercurial-ci/mercurial/worker.py", line 299, in _posixworker: No attribute 'close' on int [attribute-error] In Union[_typeshed.HasFileno, int] File "/tmp/mercurial-ci/mercurial/worker.py", line 299, in _posixworker: No attribute 'close' on _typeshed.HasFileno [attribute-error] In Union[_typeshed.HasFileno, int]

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@6.secret: 6

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: possible conflict - c was deleted and renamed to:
   a
  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
  [20]
  $ hg revert -r . -q e

Need to specify a rev:

  $ hg graft
  abort: no revisions specified
  [10]

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
  [255]

Conflicting date/user options:

  $ hg up -q 0
  $ hg graft -U --user foo 2
  abort: cannot specify both --user and --currentuser
  [10]
  $ hg graft -D --date '0 0' 2
  abort: cannot specify both --date and --currentdate
  [10]

Can't graft with dirty wd:

  $ hg up -q 0
  $ echo foo > a
  $ hg graft 1
  abort: uncommitted changes
  [20]
  $ 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'
  abort: graft in progress
  (use 'hg graft --continue' or 'hg graft --stop' to stop)
  [20]

Abort the graft and try committing:

  $ hg up -C .

  $ echo c >> e
  $ hg ci -mtest

  $ hg strip . --config extensions.strip=

  abort: unresolved merge conflicts (see 'hg help resolve')
  [20]

Fix up:

  $ echo b > e
  $ hg resolve -m e
  (no more unresolved files)
  continue: hg graft --continue

Continue with a revision should fail:

  $ hg graft -c 6
  abort: can't specify --continue and revisions

Test that the graft and transplant markers in extra are converted, allowing
origin() to still work.  Note that these recheck the immediately preceeding two
tests.
