Test disabling copy tracing

- first verify copy metadata was kept

  $ hg up -qC 2

  $ hg rebase --keep -d 1 -b 2 --config extensions.rebase=

  rebasing 2:add3f11052fa "other" (tip)

  merging b and a to b

  merging c and a to c

  $ cat b

  0

  1

  2

- next verify copy metadata is lost when disabled

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

  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

  saved backup bundle to $TESTTMP/t/.hg/strip-backup/550bd84c0cd3-fc575957-backup.hg (glob)

  $ hg up -qC 2

  $ hg rebase --keep -d 1 -b 2 --config extensions.rebase= --config experimental.disablecopytrace=True

  rebasing 2:add3f11052fa "other" (tip)

  remote changed a which local deleted

  use (c)hanged version or leave (d)eleted? c

  $ cat b

Verify disabling copy tracing still keeps copies from rebase source

  $ hg init copydisable

  $ cd copydisable

  $ touch a

  $ hg ci -Aqm 'add a'

  $ touch b

  $ hg ci -Aqm 'add b, c'

  $ hg cp b x

  $ echo x >> x

  $ hg ci -qm 'copy b->x'

  $ hg up -q 1

  $ touch z

  $ hg ci -Aqm 'add z'

  $ hg log -G -T '{rev} {desc}\n'

  @  3 add z

  $ hg rebase -d . -b 2 --config extensions.rebase= --config experimental.disablecopytrace=True

  rebasing 2:6adcf8c12e7d "copy b->x"

  saved backup bundle to $TESTTMP/copydisable/.hg/strip-backup/6adcf8c12e7d-ce4b3e75-backup.hg (glob)

  $ hg up -q 3

  $ hg log -f x -T '{rev} {desc}\n'

  3 copy b->x

  $ cd ../

Verify we duplicate existing copies, instead of detecting them

  $ hg init copydisable3

  $ cd copydisable3

  $ touch a

  $ hg ci -Aqm 'add a'

  $ hg cp a b

  $ hg ci -Aqm 'copy a->b'

  $ hg mv b c

  $ hg ci -Aqm 'move b->c'

  $ hg up -q 0

  $ hg cp a b

  $ echo b >> b

  $ hg ci -Aqm 'copy a->b (2)'

  $ hg log -G -T '{rev} {desc}\n'

  @  3 copy a->b (2)

  $ hg rebase -d 2 -s 3 --config extensions.rebase= --config experimental.disablecopytrace=True

  rebasing 3:47e1a9e6273b "copy a->b (2)" (tip)
