Looks like this patch would break the bots.  I think the problem is that you removed the --no-clean option.

> Tools/Scripts/webkitpy/common/checkout/scm/git.py:152
> +        return self._run_git(['diff', 'HEAD', '--no-renames', '--name-only']) == ""

should this be "!=" instead of "=="? Otherwise True == no changes, which is the opposite of what the method name implies.

> Tools/Scripts/webkitpy/common/checkout/scm/git.py:361
> +        # Haven't given us which commits, so use the difference to remote base.

We generally try to make our comments grammatically correct, and this is a bit too far off for me :) I would probably just delete the comment anyway, the code is pretty clear as-is.

> Tools/Scripts/webkitpy/common/checkout/scm/git.py:367
> +                force_squash = squash and squash.lower() == "true"

I'd probably collapse this to:

force_squash = force_squash or Git.read_git_config('webkit-patch.commit-should-always-squash', cwd=self.checkout-root).lower() == 'true'.

> Tools/Scripts/webkitpy/common/checkout/scm/git.py:370
> +            num_changes = len(self.local_commits()) + int(not has_working_directory_changes)

I'm not a big fan of the bool->int conversion; it's very unpythonic to me. perhaps (1 if has_working_directory_changes else 0) ? Also, seems like you don't want the 'not' here (cf. the comment in has_working_directory_changes). Also, if you collapse the lines above, you can probably get rid of the comment here as well (the whole thing will only be three lines and the logic will be obvious).

> Tools/Scripts/webkitpy/common/checkout/scm/scm.py:93
> +

probably don't need this line.

> Tools/Scripts/webkitpy/common/checkout/scm/scm.py:210
> +    #--------------------------------------------------------------------------

We don't tend to add divider lines like this ...

> Tools/Scripts/webkitpy/common/checkout/scm/scm.py:218
> +    #--------------------------------------------------------------------------

ditto.

Looks good.

> +            num_local_commits, ["clean", "not clean"][has_working_directory_changes]))

I think this part landed in a separate patch.

All reviewed patches have been landed.  Closing bug.

[Tim 'mithro' Ansell]

Still need to fix the "CleanWorkingDirectory" step to make it clear that it is actually doing a "DiscardLocalChanges".
