The two parts of #1242 that do not need repository settings access.

What is wrong today

Codecov has had no report for main since 13 June 2024, and codecov/project is consequently red on every open pull request that carries that context. From the last push-triggered run on main (run 28674157419, build-and-test):

info  - Found 1 coverage files to report
info  - Upload queued for processing complete
error - Upload queued for processing failed: {"message":"Repository not found"}

The step still reported success, because fail_ci_if_error defaults to false. That is why two years passed unnoticed.

The change

fail_ci_if_error on both upload steps, except on pull_request. A run that carries CODECOV_TOKEN now fails when its upload is rejected. Pull requests from forks have no access to the secret and upload tokenless, which is exactly the path that still works today, so they keep the tolerant behaviour. This is narrower than what I proposed in the issue, where I had suggested true everywhere; gating it this way avoids making every fork pull request depend on codecov's tokenless path staying healthy.

A weekly schedule and workflow_dispatch. .github/workflows/build.yaml last ran on a push to main on 3 July, although main has had commits since. They are dependabot auto-merges, performed by .github/workflows/auto-merge.yaml with GITHUB_TOKEN, and a push made with that token starts no further workflow run. So even with a working token, main stays dark for as long as its history is auto-merges. A weekly run gives the base something to be compared against, and workflow_dispatch makes it possible to refresh it on demand right after the token is rotated.

What this does not do

Rotating CODECOV_TOKEN to the current upload token for stackrox/kube-linter needs repository settings access. Until that happens, this change makes the rejection visible on main rather than silent - which is the point, though it does mean the first scheduled run will be red while the token is still wrong. Happy to split that part out or hold this until the token is ready, whichever you prefer.

AI-assisted (LLM used for drafting); every change verified and tested by me.

Codecov has had no report for main since 13 June 2024. The uploads are being
rejected - "Upload queued for processing failed: {"message":"Repository not
found"}" in the last push-triggered run on main - while the step still reports
success, because fail_ci_if_error defaults to false. Every pull request is
therefore compared against a base hundreds of commits behind.

Two changes, neither of which needs repository settings:

  - fail_ci_if_error on the two upload steps, set for everything except a
    pull_request event. A run that carries CODECOV_TOKEN now fails loudly when
    the upload is rejected; pull requests from forks have no token and upload
    tokenless, so they keep the tolerant behaviour they rely on.

  - a weekly schedule and workflow_dispatch on the workflow. Dependabot
    auto-merges are pushed with GITHUB_TOKEN, and a push made with that token
    starts no workflow run, so main produces no build and no coverage upload
    for as long as its history is auto-merges.

Rotating CODECOV_TOKEN is the third part and needs repository access; it is
described in stackrox#1242.

📝 Summary

Summary by CodeRabbit

  • Chores
    • Added scheduled weekly builds and tests.
    • Added an option to manually start the build-and-test workflow.
    • Adjusted coverage reporting so upload errors fail scheduled, push, and manually triggered runs while remaining non-blocking for pull requests.
    • Updated workflow permissions to follow least-privilege access practices and support security report publishing.
    • Improved automated validation reliability by explicitly detecting failed coverage uploads.

Walkthrough

The build workflow adds weekly scheduled and manual runs, conditional Codecov failure handling, and explicit permissions for build, SARIF, and Windows jobs.

codecov/project is red here too, and it stays red until the token is rotated: this branch changes when a rejected upload is reported, which does nothing for the stale base that the project check compares against. codecov/patch is green, as are build-and-test, kube-linter, test-sarif and the Windows sanity test.

One thing worth saying plainly: nothing in this pull request can be seen working until CODECOV_TOKEN is rotated. Merging it makes the next rejection visible on main instead of silent, and the scheduled run gives main a build it currently never gets.

CodeRabbit flagged build-and-test, test-sarif and windows-sanity-test as running with the repo-default GITHUB_TOKEN scope (CWE-732). Pin each job to the permissions it actually needs: contents: read for build/test, plus security-events: write on test-sarif for the SARIF upload step.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Prevent Codecov failures from skipping the remaining validation.

fail_ci_if_error makes a rejected upload fail the step. (github.com) The unit upload runs before E2E and BATS tests. The BATS upload runs before binary artifact uploads. A failed step skips later steps, and test-sarif and windows-sanity-test are skipped because they need build-and-test. (docs.github.com)

The PR states that the current token will be rejected until rotation. Move both uploads after all test and artifact-producing steps, or isolate them from the validation job and aggregate their failure afterward.

…e job

Review pointed out what the first commit cost: the unit upload runs before
the E2E and bats tests and before the binary artifacts, and two jobs depend
on build-and-test. With fail_ci_if_error alone, a rejected upload fails that
step, every later step is skipped, and test-sarif and windows-sanity-test
never start. Until CODECOV_TOKEN is rotated that would be every push to main.

Both uploads now carry an id and continue-on-error, so their outcome is
recorded rather than fatal, and a final step turns a rejected upload into a
job failure after all tests and artifact uploads have run. The visibility the
issue asked for is kept; the validation is no longer traded for it.

Good catch on the ordering, and it was the more expensive of the two findings.

fail_ci_if_error on its own does exactly what the review says: the unit upload sits before the E2E and bats tests and before both binary artifacts, and test-sarif and windows-sanity-test both need build-and-test. So on every push to main, for as long as the token is wrong, a rejected upload would have cost the repository its whole validation rather than just telling someone the upload failed. That is a worse trade than the silence it was meant to replace.

Pushed c9a27e5: both uploads now carry an id and continue-on-error: true, so a rejection is recorded rather than fatal, and the last step in the job turns a recorded rejection into a job failure:

      - name: Fail if a coverage upload was rejected
        if: >-
          github.event_name != 'pull_request' &&
          (steps.codecov-unit.outcome == 'failure' ||
           steps.codecov-bats.outcome == 'failure')

It runs after every test and every artifact upload, so the visibility the issue asked for is kept and nothing downstream is skipped to get it. Step order after the change, from the parsed workflow: unit tests, unit upload, E2E, bats, bats upload, Linux binary, Windows binary, and the check last.

The permissions finding from the first round is in 19c37ce: contents: read on build-and-test and windows-sanity-test, plus security-events: write on test-sarif for the SARIF upload.
