As discussed over IRC, I think this patch is okay, but "clean_working_directory" means something different than "reset to merge base" to me ... maybe we should rename this command/method to reset_to_master() or something?

I'm confused. We can still hit this if someone is committing locally. Why change this?

Just because the semantics of working_directory_is_clean have changed slightly.  It now tells you whether there are any changes relative to the merge base, so we don't know if there are uncommitted changed in the working copy.

Interesting idea.  The trickiness is that we need a name that makes sense for SVN too.

Yeah, dunno ... If we can't come up with a better name we should at least add a comment or a docstring describing the intent of the method (to prepare the checkout so that we can update cleanly) ... maybe clean_for_update() or prepare_for_update() or something?

This makes webkit-patch land -g HEAD to fail complaining that working copy is not clean, even though it's clean. The problem is that working_directory_is_clean() not gets the diff between HEAD and remote_merge_base(), which is the commit you want to land.

I see. It's unfortunate losing this extra information about why the commit failed. I've hit this before and it's saved me debugging time.

Also, really we should probably rename working_directory_is_clean to checkout_is_clean or something like that and clean_working_directory to clean_checkout maybe? I agree w Dirk. The code is now confusing.

I filed bug 104198 about this issue.  Hopefully I'll get a patch written tomorrow, but it might need to wait until Jan.  Sorry for making this code more confusing.  :(
