Remove Circular dependency between Resolver and Preparer #4636

pradyunsg · 2017-07-31T17:20:17Z

Does what it says in the title.

Sidenote: GitHub went down when I was running tests and I was totally baffled by the fact that the tests were failing.

Note to pip committers: @pradyunsg offered to wait for PR #4644 to be committed (which was originally submitted in April and has since been approved) before committing this.

This if-check was moved into _check_skip_installed() in my earlier PR.

I think it would be helpful to include a docstring stating the type of the argument and return values.

Done.

FWIW, I'll be adding type comments to various parts of the codebase once the mypy PR merges.

Formatting: I would do "NOTE: the following ...."

When I do it that way, I have an urge to indent the rest of the text to align with the colon, which feels like a waste of space. That's why I ended up doing this. :P

This code comment doesn't make sense / isn't a sentence?

I copy-pasted it. I don't want to change it as a part of this PR since I'm more concerned with moving stuff than improving things.

Thanks for the review @cjerdonek! ^.^

I'm not that familiar with this code, but I'll try to review it over the weekend.

Pinging @dstufft! :)

Ping @dstufft @pfmoore!

pradyunsg · 2017-10-20T09:45:57Z

Note: Would conflict with #4764. :)

pfmoore · 2017-10-20T09:53:42Z

I didn't say which weekend ;-)

Thanks for the reminder.

pradyunsg · 2017-10-22T15:53:18Z

Hi @pfmoore and @dstufft!

It'd be awesome if you guys could take a look at this.

A summary would be cut-paste a single function from one file to another + renaming some 4 methods in all, whose signatures change to take the values that they care about (instead of the larger Resolver object that holds the references to those objects).

pfmoore · 2017-10-22T16:56:49Z

I was just in the process of going to take a look when I saw the ping :-)

LGTM - I assume you'll fix up #4764 after merging this? Ping me if you need a quick review on #4764 after that, but as it'll just be mechanical changes to take care of the refactoring here, I assume it'll be pretty straightforward.

pradyunsg · 2017-10-22T17:02:18Z

Thanks a lot @pfmoore!

Ping me if you need a quick review on #4764

I will. :)

RequirementPreparer no longer takes Resolver as argument in any of its methods and directly takes the reference of the values it actually needs.
