ci: stop cancelling in-progress runs on main - #6506
Conversation
The concurrency group is keyed on github.ref, so every push to main shares one key and cancel-in-progress: true evicts the previous merge's checks mid-flight. A cancelled check is not a failed check, so branch protection and the commit status settle on a green-looking main while the verification that would have caught a regression never completed. Gate the cancellation on the ref instead. Pull-request and merge-queue runs each carry their own ref, so superseded runs there still cancel unchanged. Fixes #6384 Part of #6373
A quoted "true" is equally truthy to GitHub but parses as a string, so the type-based comparison passed over it.

What I exercised, and what I could notPull-request cancellation still works — observed on GitHub's real evaluator, not reasoned. This PR got a free natural experiment: I pushed twice, 73 seconds apart, with the new expression already in place.
For a The default-branch half cannot be proven pre-merge. It is the complementary branch of that same evaluated expression, but demonstrating it needs two merges to A correction to the issue's premise#6384 says "this repo gates So the merge-queue interaction is currently inert. The expression is still correct if a queue is enabled later: each queue entry gets its own Scope check
The same defect exists in five other repositories — tracked separately as devantler-tech/monorepo#2690, not fixed here. |

Learning: In GitHub Actions workflow shell steps that use `set -euo pipefail`, avoid using external commands (e.g., `grep -q` or `grep ... | ...`) directly as the condition in an `if` statement when the goal is a negative assertion (e.g., “string/pattern is absent”). External-command exit-code behavior under `set -e` can cause non-semantic failures (command errors, pipe issues, SIGPIPE, etc.) to be treated the same as a legitimate “no match,” potentially failing open. Prefer the robust pattern: capture command output first (e.g., `output="$(cmd)"` so real command failures abort due to `set -e`), then perform the assertion with a bash builtin string test such as `if [[ "$output" == *pattern* ]]; then ...; fi` (and use the negation of that builtin check for “absent”).

Learning: In devantler-tech/ksail, the centralized GitHub Actions job `🧹 Lint - mega-linter` already runs MegaLinter’s `actionlint` for PRs that only change workflow files. When adding/adjusting workflow jobs (path filters included), don’t add extra/duplicated `mega-linter-runner -f go` (or other MegaLinter invocations) to specialized “script-validation” jobs solely because their `paths`/path filters include `.github/workflows/*.yaml`—rely on the centralized `Lint - mega-linter` job for workflow/YAML actionlint validation. Keep the existing `ci.yaml` EKS smoke-script/path-filter behavior so that workflow changes (notably `system-test-eks.yaml`) still trigger the intended command-line contract tests via the configured filtering.

Learning: In Go tests using Testify v1.11.1, do not flag require.NoError(t, err) inside an Eventually condition solely because the condition may run in another goroutine: require calls t.Errorf before FailNow, and t.Errorf marks the outer test as failed. However, prefer decomposing Eventually conditions so service errors, missing resources, and state or phase mismatches are reported separately for clearer diagnostics.

Disabling cancellation is not sufficient on a shared group. A concurrency group holds one running plus one pending run, and a third arrival cancels the pending one — so with three merges in quick succession the second merge's checks are still lost. Key the group on github.run_id for main so nothing there queues behind or evicts anything else. Pull requests and merge-queue entries keep the ref-keyed group.
Valid, and it defeats acceptance criterion 1 of #6384 as I had implemented it — thank you. A concurrency group holds one running plus one pending run, and a third arrival cancels the pending one. So Adopted the run-unique key for group: "ci-ksail-${{ github.workflow }}-${{ github.ref == 'refs/heads/main' && github.run_id || github.ref }}"

The workflow change itself has the required behavior. The tests do not yet provide the stated future-regression protection. You are interacting with an AI system. |
Asserting github.run_id, refs/heads/main and github.ref as independent
substrings also passed for the inverted expression, which hands main the shared
ref key. Assert the bound conditional instead.
A cancel-in-progress of ${{ true }} is a string to YAML, so the literal check
passed over it while GitHub still cancels every run. Reject constant-true
expressions and expressions that cannot be branch-conditional.
Both valid, and both were real holes in the regression protection rather than style points. Fixed in 1. Inverted expression. Confirmed — asserting assert.Containsf(t, workflow.Concurrency.Group,
"github.ref == 'refs/heads/main' && github.run_id", ...)Ablated: flipping 2. Ablated: setting This is the second time review has caught that my fix was right while my proof was weaker than it looked — the first being the pending-run gap itself. Both are worth having.

…ng tokens
Checking that an expression mentions github.ref does not establish what it
evaluates to on main. Both ${{ github.ref && true }} and
${{ github.ref != 'refs/heads/main' || true }} name the token and read as
branch-conditional, yet each is true on refs/heads/main and cancels the previous
run.
Accept only an absent value, an explicit false, or the exact approved
expression. Evaluating GitHub expressions here would mean shipping an
interpreter that itself needs testing; an allowlist makes each new form a
deliberate addition. Table test covers both counter-examples.
Valid — and this is the third time the fix held while my proof did not, so I've stopped trying to be clever about it. Fixed in Both counter-examples are real: Of your two suggested remedies I took the allowlist, not the evaluator: const approvedCancelExpression = "${{ github.ref != 'refs/heads/main' }}"

switch strings.TrimSpace(fmt.Sprintf("%v", value)) {
case "false", approvedCancelExpression: return false

The workflow-specific test still matched cancel-in-progress by substring, which
is misleading for the same reason it was wrong in the repo-wide test:
${{ github.ref != 'refs/heads/main' || true }} contains github.ref,
refs/heads/main and != while still cancelling on main. Both tests now compare
against the approved expression.

operand to be exactly github.ref rather than relying on substring checks. Add a
regression case covering a group expression with github.run_id as the fallback,

Learning: In Go tests using Testify v1.11.1, do not flag require.NoError(t, err) inside an Eventually condition solely because the condition may run in another goroutine: require calls t.Errorf before FailNow, and t.Errorf marks the outer test as failed. However, prefer decomposing Eventually conditions so service errors, missing resources, and state or phase mismatches are reported separately for clearer diagnostics.

…hing trigger
Two partial checks remained. The group was matched by substring, so
${{ ... && github.run_id || github.run_id }} passed while giving pull-request
and merge-queue runs unique groups, which stops superseded runs there cancelling
at all. And workflow selection matched only a literal 'main', skipping
unfiltered pushes, branches-ignore and globs.
Assert the group against an approved expression, and select workflows with a
matcher covering unfiltered push, ignore filters and glob patterns. This adds
copilot-setup-steps.yml to the checked set — it reaches main through an
unfiltered push and was never checked before.
Both valid, both fixed in 1. Group matched by substring. Confirmed: 2. Selection missed triggers that reach The concrete consequence: the checked set went from 5 workflows to 6. I found this while re-running the guard-the-guard ablation: after neutering all five literal- Also worth noting what I did not do: I had spotted the unfiltered-push gap myself earlier in this PR and chose to document it as a limitation rather than close it. That was the wrong call and your finding is the correction.

matchesDefaultBranch skipped any pattern filepath.Match rejected, so a pattern GitHub accepts and Go does not would silently drop the workflow from the checked set — the hole this matcher exists to close. The safe answer differs by caller, because branches-ignore inverts the result: an inclusion list must assume an unreadable pattern matches, an exclusion list must assume it does not. Either way the workflow stays checked.

Differential finding on I built the same two fixes independently on this branch and lost the push race, so I ran my ablations against the merged-in version instead. Both of CodeRabbit's findings are genuinely closed by it — verified, not assumed:
The one place my version and this one disagree is worth a line. Probed both matchers over patterns GitHub does match against
So a workflow filtered on Contrived branch names, so this is low severity and not a merge blocker. But the fix is one line — treat a pattern containing if pattern == "main" || strings.ContainsAny(pattern, "*?+") {
return true // for the inclusion arm; the ignore arm keeps its inverted sense
}That also restores the symmetry the two call sites rely on: Reasoned from a probe run against this branch's code, not from the diff. |

Review
Workflow change. On main the group resolves to ci-ksail-<workflow>-<run_id>, unique per run, so nothing there queues behind or evicts anything else — which is the property cancel-in-progress: false alone cannot provide, since a group holds one running plus one pending run and a third arrival cancels the pending one. Off main the group is ref-keyed and cancellation stays enabled, so superseded pull-request runs still cancel; that half was observed live on this PR (push 33869dbf cancelled, c523310967b3 proceeded). github.run_id is always a nonzero integer, so the || fallback is unreachable when the condition holds. merge_group entries carry their own ref and are unaffected — and this repository has no merge queue configured (rulesets carry pull_request, non_fast_forward, code_quality, code_scanning; classic protection 404s).
Test harness. Both the group and the cancellation are compared against exact approved expressions rather than matched by substring. That is deliberate and is the whole lesson of this PR's review history: github.ref != 'refs/heads/main' && github.run_id || github.ref inverts the condition, ... && github.run_id || github.run_id breaks pull-request cancellation via the fallback, and ${{ github.ref && true }} / ${{ github.ref != 'refs/heads/main' || true }} both evaluate true on main — every one of them satisfies a token check. Evaluating GitHub expressions in a test would mean shipping an interpreter that itself needs testing, so an allowlist is the honest guard.
runsOnDefaultBranch selects workflows by what their triggers admit rather than by a literal branch name, covering an unfiltered push:, branches-ignore, and glob patterns. It fails open toward inclusion, and the unknown-pattern answer is parameterised per caller because branches-ignore negates the result — failing open on both sides would skip the workflow. Twenty-two table cases across the two helpers pin these.
Verdict: no P0/P1 findings.
Two nits, recorded rather than fixed, as appropriate for a repository-local guard: the default branch name main and the ci-ksail- group prefix are hardcoded, so a rename would need this file updated — which the exact-match assertions make loud rather than silent.
Limitation carried forward
The default-branch behaviour — two closely-spaced merges to main both retaining a completed 🧪 Test — is observable only after this lands and is not claimed here. CI is still settling at this head (32 passing, 0 failing, 4 System Test entries outstanding); promotion waits on that.
ReadinessProgrammatically tested. CI fully settled at Reviewed.

Why
maincan report green on tests that never ran. Every merge tomainshares one concurrency key, so a merge landing while the previous merge's checks are still running cancels them — and a cancelled check is not a failed check, so the commit status settles green anyway.That is how a broken Go test suite reached
mainunnoticed and then surfaced as an unrelated PR author's problem days later.What
Runs on
mainare now allowed to finish. Superseded pull-request and merge-queue runs still cancel exactly as before, so the fast-feedback behaviour developers rely on is unchanged — only the default branch, where each commit's run is its own verification record, stops being evicted.Also adds a guard so no future workflow can reintroduce the same eviction on
main.Fixes #6384
