Rebase a simple DAG:

  $ hg init repo1

  $ cd repo1

  $ hg debugdrawdag <<'EOS'

  > c b

  > |/

  > d

  > |

  > a

  > EOS

  $ hg up -C a

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg tglog

  $ hg cat -r 3 c

  $ hg rebase --debug -r b -d c | grep rebasing

Add a symlink and executable file:

  $ hg up -C c

  3 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ ln -s somefile e

  $ echo f > f

  $ chmod +x f

  $ hg add e f

  $ hg amend -q

  $ hg up -Cq a

Write files to the working copy, and ensure they're still there after the rebase

  $ echo "abc" > a

  $ ln -s def b

  $ echo "ghi" > c

  $ echo "jkl" > d

  $ echo "mno" > e

Ensure working copy files are still there:

  $ cat a

  abc

  $ readlink.py b

  b -> def

  $ cat e

  mno

Ensure symlink and executable files were rebased properly:

  $ hg up -Cq 3

  $ readlink.py e

  e -> somefile

  $ ls -l f | cut -c -10

  -rwxr-xr-x

Rebase the working copy parent

  $ hg up -C 3

  $ hg rebase -r 3 -d 0 --debug | grep rebasing
