[JENKINS-75704] Fix Copilot user null name/email handling #864

IvanGasant · 2025-06-10T08:50:19Z

Description

This PR improves the handling of pull requests and commits authored by GitHub IA, Copilot, who may not have a real GitHub account or may lack a defined name or email.
It prevents exceptions and ensures that these contributions are not discarded during indexing or processing.

Changes

Special handling for the "copilot" user:
- If a pull request is authored by a user with login "copilot", a synthetic ContributorMetadataAction is created with:
  - Name: "copilot"
  - Email: "copilot@unknown.user"
- This ensures PRs from Copilot are processed and visible, even though "copilot" is not a real GitHub user.
Other users:
- For all other users, the contributor metadata is still created using the values returned by the GitHub API (login, name, and email) with no fallback.
  If user.getName() or user.getEmail() are null, those fields will remain null as before.
Unchanged logic for missing users:
- If the user does not exist (for example, if the API returns 404), the PR is still ignored just like before.

Motivation

GitHub Copilot and other bots can appear as authors of commits and pull requests, but may not exist as real users in GitHub.
Without this special handling, such PRs would be discarded or cause exceptions, impacting the visibility and traceability of AI-generated or bot-generated contributions.

See JENKINS-75704 for further information.

Submitter checklist

Link to JIRA ticket in description, if appropriate.
Change is code complete and matches issue description
Automated tests have been added to exercise the changes

No automated tests were added because this is a trivial change: it only handles null values or exceptions when fetching the GitHub user's name/email for logging purposes, defaulting to safe values if missing. It does not affect business logic or the core functionality of the plugin.

Reviewer's manual test instructions provided in PR description. See Reviewer's first task below.

Users/aliases to notify

…pdate tests - Updated logic so that only the copilot user is allowed to bypass missing name and email checks in pull request processing. - All other users without name/email are marked as unknown and a log message is generated. - Added and updated tests to verify that copilot is accepted and handled as expected.

Fallback for missing user name or email:

* For all other users, if `user.getName()` or `user.getEmail()` are `null` or throw exceptions, the code now defaults to:
  
  * Name: `user.getLogin()`
  * Email: `user.getLogin() + "@unknown.user"`

* This prevents exceptions when processing PRs or commits from bot users or users with incomplete profiles.

I see no evidence of such a change in the current patch; did you revert it? If so, please update the PR description accordingly.

IIUC this was just false.

Dear @jglick and @IvanGasant , Do you have an estimated timeline for merging this pull request and creating a new release? I'm particularly interested in this fix, as it's currently blocking some of our Jenkins CI/CD workflows when Copilot creates pull requests in our repositories.

Thank you!

It would be nice if @IvanGasant could manage the comments to merge this PR.
The fix helps us use Copilot in systems with Jenkins in their pipelines.
