plugins: add new plugin for linking and unlinking issues to a PR #556

Amulyam24 · 2025-11-25T14:53:08Z

This PR adds a new plugin issue-management which has commands for linking and unlinking issues to a PR.
Ref - https://docs.github.com/en/issues/tracking-your-work-with-issues/using-issues/linking-a-pull-request-to-an-issue

The commands can be used to link an issue to a PR in the current repository or in a different repository as well as handle multiple issues
This is done by adding the supported keyword Fixes to the body of the PR if it doesn't already exist or by appending the issue to the existing Fixes line
Supported formats are issue-number and org/repo-name#issue-number

A new plugin has been added to accommodate any existing issue commands or provide flexibility to support more issue commands in the future.

Fixes #359

Just FYI, current guidance is to not include the year for these copyright headers. I don't think it matters, just pointing it out to help spread awareness.

I don't believe there is a reason for defining this interface unless you are going to mock it for unit testing. Is that planned as a follow up? Might be good to have that included in this PR.

Yes, I was planning that as a follow up. Sure, I'll add it to this PR.

Hi @stmcginnis, I explored a couple of ways on adding the UT.

At the end I feel having this interface and using the existing fake client is convenient than mocking the githubClient or using the plugins.PluginGitHubClient directly instead of githubClient as that would need mocking as well.

PTAL and let me know your thoughts!

Having a small local interface is somewhat established pattern in GH-facing plugins (retitle, blunderbuss), the GH client interface surface is massive and it is often useful to have an idea of what GH operations the plugin is limited to (besides the mentioned test mock use case). I'd prefer to keep it.

@Amulyam24: The label(s) `/label do-not-merge/work-in-progress

cannot be applied. These labels are supported:api-review, tide/merge-method-merge, tide/merge-method-rebase, tide/merge-method-squash, team/katacoda, refactor, ci-short, ci-extended, ci-full. Is this label configured under labels -> additional_labelsorlabels -> restricted_labelsinplugin.yaml`?

I think this is pretty close, I appreciate the test coverage. Left some comment about the code structure.

Hi @petr-muller, was out for year end vacation. Most of the review comments are in place, will be working on enhancing the logic as mentioned above and push the changes this week, Thanks!

Amulyam24 · 2026-01-09T14:38:11Z

hi @petr-muller, I have updated the logic to handle both link and unlink and tested possible scenarios. UT has been added accordingly. The PR is ready for review, PTAL, Thanks!
