fix(ci): let the fork e2e lane check out the pull request again - #4514
Conversation
actions/checkout v4.4.0 refuses to check out a fork's pull request ref from a workflow_run workflow unless the step opts in. The Renovate roll-up that moved e2e-fork.yaml to v4.4.0 made the publish job fail at checkout for every fork PR, so the required "E2E Tests" status now goes red on all of them regardless of the change. The lane was built to take fork code this way: publish runs no fork-authored script and e2e holds no push token. Opting in restores the behaviour it had on v4.3.1, and a unit test fails if either pull-request checkout loses the opt-in. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <[email protected]>

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe fork E2E workflow now opts into unsafe checkout for pull-request merge refs in both the publish and e2e jobs. A Bats test checks that each pull-request checkout sets the opt-in to true. ChangesFork PR checkout

The workflow separates those tests from registry push credentials, but safe operation also depends on a repository approval setting that could not be verified. Retained concerns

25-26: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winRequire a pull-request checkout in both jobs.
The current workflow has one checkout in
publishand one ine2e, but the first test requires only onerefs/pull/record. If either job loses its ref, the other record satisfies both tests. Assert that both checkout steps retain pull-request refs.Suggested fix

What this PR does
Every fork pull request has a red "E2E Tests" status since the Renovate roll-up in #4447 moved
e2e-fork.yamlto actions/checkout v4.4.0. That release refuses to check out a fork's pull request ref from aworkflow_runworkflow unless the step setsallow-unsafe-pr-checkout: true, so the publish job stops at its first step and the e2e run never starts.This sets the opt-in on both pull-request checkouts in the workflow, which gives back the v4.3.1 behaviour. The lane already takes fork code on purpose and its header describes the boundary:
publishruns no fork-authored script ande2eholds no push token. A new unit test,hack/fork-pr-checkout_test.bats, fails if either checkout loses the opt-in. Removing it from one step turns the test red under both bats andhack/cozytest.sh.Closes #4513
