Thanks for working on this!

I think this patch does too much at once. At least the help message change should be moved to a separate patch. Ideally, the other changes would also be split up. Perhaps something like this:

  1. Move unfinishedstates, checkunfinished, and clearunfinished (without changing them) to the new module.
  2. Create and use the statecheck class, but only let it handle what's needed for unfinishedstates so far.
  3. Add the functionality from STATES to the new module and update the already existing users, but leave the cases that are handled by STATES unchanged for now.
  4. Switch existing users of STATES over to the new module (and delete STATES)
  5. Change messages to the new "To continue: ..." form. I'm not sure we want that change, or we'll probably at least want to make some, so this one is extra important to keep separate.

You don't have to follow those steps exactly, of course. You know the code better, so maybe some of what I suggested doesn't make sense.

Pass at least the boolean arguments as named arguments (clearable=False etc)

@martinvonz I have completed steps 1 to 5 as you stated in the sequence above in statecheck.py. For the purpose of showing that it works without flaw, I redirected the API calls to the new API for both STATES and unfinished state and removed those from cmdutil.py. All that remains is a minor bug that I am facing with hg bisect. I will clear that soon enough. Do you want me to send the API integration and tests as a separate patch and API as another?

I think @martinvonz wants to say that we should split the whole work into nice small commits. This will help us to review it better and understand the whole change much better. The 1 to 5 are like, one commit should do one of those things.

I also agree with him, what do you think?

taapas1128 added a comment.Jun 7 2019, 2:40 AM

@pulkit okay I will split this into 5 commits.

@martinvonz have a look at this stack now . It is strictly according to your guidelines.

martinvonz accepted this revision.Jun 8 2019, 5:47 PM

Thanks for splitting this out! Sorry about being so particular about splitting up the patch. I think it's an important part of writing patches that others will review. Hopefully it wasn't just frustrating and you can also see some benefit with it. The benefit is mostly to reviewers and future code archeologists and not to the author, so it can feel like wasting time. Remember that more people will read the patches than the people writing them (which is just you).

This revision is now accepted and ready to land.Jun 8 2019, 5:47 PM
taapas1128 added a comment.Jun 9 2019, 6:05 AM

@martinvonz At first I didn't seem to realize why the patches need to be split that way but later I realized that I wasn't looking from the perspective of a reviewer but was just getting the job done as an author. Thanks for making me work this out :)

I wonder if we should keep the functions in cmdutil.py and let them delegate to the new ones. That way we won't have to update all the callers. I think cmdutil sounds like a more natural place for the callers to looks for this function. That's also where bailifchanged() is, so it it makes sense that these two similar functions are in the same place.
