Create a repository:
|
|
|
|
$ mkdir t
|
|
$ cd t
|
|
$ hg init
|
|
|
|
Make a changeset:
|
|
|
|
$ echo a > a
|
|
$ hg add a
|
|
$ hg commit -m test
|
|
|
|
This command is ancient:
|
|
|
|
$ hg history
|
|

Verify that updating to revision 0 via commands.update() works properly
|
|
|
|
$ cat <<EOF > update_to_rev0.py
|
|
> from mercurial import ui, hg, commands
|
|
> myui = ui.ui()
|
|
> repo = hg.repository(myui, path='.')
|
|
> commands.update(myui, repo, rev=0)
|
|
> EOF
|

$ hg up null
