Failed Job: test-go-pg (macos-latest) https://github.com/coder/coder/actions/runs/22303873776/job/64518157527
Aggregator failure: required job failed because test-go-pg was cancelled

Commit Info:

• Message: fix(coderd): harden OAuth2 provider security (#22194)

Failure evidence:

• required job output:

- test-go-pg: cancelled
One of the required checks has failed or has been cancelled

• macOS job log (test step):

2026-02-23T11:24:37Z ok 	github.com/coder/coder/v2/cli 100.025s
2026-02-23T11:44:25Z ##[error]The operation was canceled.

Timeline / timeout context:

• test-go-pg job has timeout-minutes: 25 in .github/workflows/ci.yaml.
• Job started at ~11:19:13Z and was cancelled at 11:44:25Z (≈25 minutes).
• No further test output appeared between 11:24:37Z and cancellation, suggesting the make test step hung or stalled and hit the job timeout.

Root cause classification: Infrastructure / test suite hang

• The macOS test-go-pg job exceeded the 25-minute job timeout during make test (gotestsum over ./cli/... ./enterprise/cli/... ./agent/...).
• No WARNING: DATA RACE, panic, or OOM indicators found in the job log; cancellation is consistent with the workflow timeout rather than a specific test failure.

Assignment analysis (component / infra ownership):

• No specific test function identified (gotestsum standard-quiet output stops before hang), so test-level blame isn’t possible.
• Using infra ownership fallback:
  • git log --oneline -10 .github/actions/test-go-pg/action.yaml
    • 7d558e7 fix: make make test runnable again (Danny Kopping)
    • 84b7a03 chore: abstract pg test logic and double runner sizes (Danny Kopping)
• Assigning to @dannykopping as the most recent meaningful maintainer of the test-go-pg action and parallelism logic.

Related issues search:

• Searched coder/internal for: "test-go-pg macos cancelled", "operation was canceled", "test-go-pg timeout", "job timeout" — no matching open issues found.

Reproduction:

• Re-run the CI workflow on main and watch test-go-pg (macos-latest).
• Locally on macOS: TEST_PACKAGES="./cli/... ./enterprise/cli/... ./agent/..." make test (observe for hang or unusually long runtime).
