error message any suggestions?

Perhaps Branch ${branch} already exists

^ so at least it indicates which branch.

When we are creating the pull request and the branch exists can we recover somehow?

E.g. delete the branch then create. Or Maybe have a unique I'd for the branch we are creating (using UUID) to avoid collisions?

I prefer the second suggestion.

Yeah I think so to.

Alternatively if there was a way to differentiate between 'you already have a branch open' and 'you already have a pull request open'. The pull request being checked first tho.

What are your thoughts on the best User Experience here?

If the branch exists, whether or not the pr is opened, we update the file on the existing branch.

Create a unique branch so that it is the easiest and the smallest to change

If the branch is already open, I think that the bot should be able to (re)-use it.
If the PR is already open then it shouldn't be doing anything unless it's changing/adding/removing something else.

To re-use the branch, we need to re get the original sha's / generate off the branch (not master/the default branch).

😅

Yes that may make the most sense

sinchang · 2019-01-17T04:05:30Z

some cases:

branch not exists and pr not open - create branch and open pr
branch exists and pr not open - update branch and open pr
branch exists and pr open - update branch
branch exists and pr closed - update branch and create a new pr

still, need to add some tests.

jakebolam · 2019-01-17T07:25:51Z

@sinchang those cases look good. This one is hard, keep at it!

Berkmann18 · 2019-01-17T12:16:27Z

Here's one more case (although casi unlikely to occur):
5. branch doesn't exist but there's a pr open - move the pr to the correct branch

I think that's all possible cases unless we're missing a variable/factor?

What would be the advantage and reason for not handling situations where this.github.git.createRef fails and throws an error?

This catch and error thrown should be done in the createPullRequest method

Can we add a link?
I've updated the [pull request](INSERT_LINK_HERE) you have open.

I don't think this should error too, could we handle this as a reply case here: (https://github.com/all-contributors/all-contributors-bot/blob/master/src/processIssueComment.js#L65-L67) e.g. can throw the error, but catch it here

This block should happen after fetching config IMO

This block should happen inside the processAddContributor block. (For future support of other actions)

This is a really good solution @sinchang! Thanks for doing this.

Overall really happy with the approach!

Just some comments/feedback to make it easier for future developers to understand (please reply to my comments if you think they don't make sense).

I wonder how we can take the latest master file and overwrite the current branch :think: like a rebase

We probably shouldn't address this here. This is probably a whole ticket in itself. #62.
I'm interested in hearing how you would solve this problem tho.
