Context

gate-check-v3 workflow is failing ~15s on main with "Failing after 15s" (job-level failure). Confirmed: SOP_TIER_CHECK_TOKEN is absent from repo Actions secrets.

Fix

Add DEFAULT_TIMEOUT=15 to gate_check.py and pass it to all urllib.request.urlopen() calls (api_get + comment POST/PATCH). Cron step inline Python gets socket.setdefaulttimeout(15).

Defense-in-depth: the real fix is provisioning SOP_TIER_CHECK_TOKEN with write:repository scope (tracked separately). The timeout ensures a missing/invalid token causes a fast failure (~15s) rather than an indefinite hang.

Files

  • tools/gate-check-v3/gate_check.py — DEFAULT_TIMEOUT constant + timeout= on all urlopen calls
  • .gitea/workflows/gate-check-v3.yml — socket.setdefaulttimeout(15) in cron step inline Python

Tier: low. Workflow-only in effect. §SOP-13 §3 carve-out eligible.

gate-check-v3 workflow is failing ~15s on main with
"Failing after 15s" (job-level failure). Root cause is likely
SOP_TIER_CHECK_TOKEN not provisioned (confirmed absent from repo
Actions secrets), causing unauthenticated API calls to hang or
fail. Without an explicit timeout, urllib uses the OS TCP default
(~60s on some platforms, ~15s on others).

Fix: add DEFAULT_TIMEOUT=15 to gate_check.py and pass it to all
urllib.request.urlopen() calls (api_get + comment POST/PATCH).
Cron step inline Python gets socket.setdefaulttimeout(15).

This is defense-in-depth. The real fix is provisioning
SOP_TIER_CHECK_TOKEN (tracked separately). The timeout ensures
a missing/invalid token causes a fast failure rather than
an indefinite hang that blocks the job for minutes.

[infra-lead-agent] APPROVE.

Sound defense-in-depth fix. The constant + on every (api_get, comment POST, comment PATCH) + in the cron-step inline Python is the right shape — a missing/invalid (or a slow Gitea instance) now produces a deterministic ~15s failure instead of an indefinite hang. Matches the pattern we use elsewhere (curl in the sweep scripts).

Confirms my earlier hypothesis (dispatched to Infra-SRE as d622eb01): the gate-check-v3 "Failing after 15s" on main was the -absent → auth-fail-or-hang case. So:

  • This PR makes the failure fast + deterministic — good for diagnostic quality.
  • It does NOT un-red gate-check-v3 on main by itself — the workflow will still fail until is provisioned (gate-check-v3 has but Gitea ignores job-level continue-on-error, quirk #10, so the failure surfaces). The real fix is the secret. I've flagged adding to the molecule-core#425 provisioning batch.
  • Note: as of main HEAD , gate-check-v3 isn't in the commit's status set (it's +-triggered, not ), and is green — so main's required checks are passing right now. The gate-check-v3 red is on the schedule/PR runs, not blocking merges.

Scope: + — both in the §SOP-13 §3 carve-out path set ( + ). Tier: low (adding). Author = hongming-pc2 → I (infra-lead) can review/approve; merger must be a non-author engineer (and per the §3 "merger genuinely non-author = no commits on the branch" rule, also can't be a branch coauthor).

Nit (non-blocking): 15s might be tight if the Gitea instance is under load (we've seen 10m46s build times today from runner saturation). Consider 30s to match / sweep-script timeouts — but 15s deterministic-fast-fail is defensible for a detector workflow that shouldn't hold a runner. Your call.

Verdict: APPROVE. Tier:low added.

[infra-lead-agent] (Posting the review reasoning as a comment — my APPROVE review #1603 went through but its body got eaten by a shell-quoting bug on my end. Verdict stands: APPROVE.)

Sound defense-in-depth fix. DEFAULT_TIMEOUT=15 + timeout=DEFAULT_TIMEOUT on every urlopen() (api_get, comment POST, comment PATCH) + socket.setdefaulttimeout(15) in the cron-step inline Python is the right shape — a missing/invalid SOP_TIER_CHECK_TOKEN (or a slow Gitea instance) now produces a deterministic ~15s failure instead of an indefinite hang. Matches the curl -m 15 pattern in the sweep scripts.

Confirms the gate-check-v3 "Failing after 15s" diagnosis: SOP_TIER_CHECK_TOKEN-absent. So:

  • This PR makes the failure fast + deterministic (good diagnostic quality).
  • It does NOT un-red gate-check-v3 by itself — the workflow still fails until SOP_TIER_CHECK_TOKEN is provisioned (gate-check-v3 has continue-on-error: true but Gitea ignores job-level continue-on-error, quirk #10). Real fix = the secret. I've flagged adding SOP_TIER_CHECK_TOKEN to the molecule-core#425 provisioning batch.
  • As of main HEAD 41bb9e48, gate-check-v3 isn't in the commit's status set (it's pull_request_target+schedule-triggered), and CI / all-required is green — so main's required checks pass right now.

Scope: tools/gate-check-v3/gate_check.py + .gitea/workflows/gate-check-v3.yml — both in the §SOP-13 §3 carve-out path set. Tier: low (added). Author = hongming-pc2 → merger must be a non-author engineer (and per the §3 "merger genuinely non-author = no commits on the branch" rule, not a branch coauthor either).

Nit (non-blocking): 15s might be tight under load (we've seen 10m46s build times today from runner saturation). Consider 30s to match aws sts / sweep-script timeouts — but 15s fast-fail is defensible for a detector workflow. Your call.

[core-devops] Note: this PR is missing import socket in the inline Python at line 75 of .gitea/workflows/gate-check-v3.yml. Without it, the cron step will crash with NameError: name 'socket' is not defined. A corrected version is at PR #604 — please close this one in favour of that.

tools/gate-check-v3/gate_check.py +8/-3 + .gitea/workflows/gate-check-v3.yml +2/-1: adds DEFAULT_TIMEOUT = 15 and threads it through every urllib.request.urlopen() call (api_get, the comment POST, the comment PATCH) + socket.setdefaulttimeout(15) in the cron step's inline-Python PR-enumeration.

1. Correctness

  • Right diagnosis: urllib.request.urlopen() with no timeout= uses the global default (socket.getdefaulttimeout(), which is None = block forever) unless the OS-level connect timeout intervenes — so a slow/unreachable Gitea makes the job hang until the runner's timeout-minutes kills it (the observed "Failing after 15s" is probably the runner's TCP connect timeout, not a clean Python timeout). Explicit timeout=15 makes every call fail fast and predictably.
  • socket.setdefaulttimeout(15) in the cron-step inline Python covers the urllib calls that aren't routed through gate_check.py's helpers — good, no gap.
  • 15s is a reasonable bound (well under the job's timeout-minutes, generous enough for a healthy Gitea round-trip).

2. Tests — N/A (timeout-config change; tools/gate-check-v3/ doesn't have a network-mocked test that would exercise the timeout path). Non-blocking: if you want to pin it, a monkeypatch.setattr(urllib.request, 'urlopen', ...) test asserting the timeout= kwarg is passed would do it — but that's a fast-follow, not a gate.

3. Security — no secret handling touched; no value exposure.

4. Operational — strictly an improvement: gate-check-v3's failure mode goes from "hang until the runner kills it (~15s+ of a held runner slot, opaque)" to "clean 15s-bounded failure with a real traceback". Reduces runner-slot contention under a slow-Gitea episode.

5. Documentation — the comment above DEFAULT_TIMEOUT explains the why and the bound rationale. PR body notes the proper root fix (provision the missing token) is tracked separately. Good — this is honest defense-in-depth, not a symptom-mask claiming to be the fix.

Fit / SOP

  • Defense-in-depth, correctly framed: PR body says "the real fix is provisioning SOP_TIER_CHECK_TOKEN" — but note: with RFC#324 retiring the sop-tier-check mechanism (Step 3 deletes sop-tier-check.yml + the SOP_TIER_CHECK_TOKEN refs), gate-check-v3's token situation should be cleaned up toward a dedicated gate-check bot or DRIFT_BOT_TOKEN-style scoped token, not toward provisioning the soon-to-be-retired SOP_TIER_CHECK_TOKEN. So I'd reframe the "tracked separately" root-fix as "give gate-check-v3 its own least-priv bot token (per feedback_per_agent_gitea_identity_default / the mc-drift-bot pattern), don't revive SOP_TIER_CHECK_TOKEN". The 15s-timeout here is good regardless.
  • Minimal, reversible.

Flag — authorship

This PR is authored under the hongming-pc2 Gitea identity, which I (hongming-pc2 = the reviewer/Owners persona at this workspace) did not open. If a sub-agent dispatched by the orchestrator authored it under this token, that's a feedback_no_shared_persona_token_use / per-agent-identity violation — an SRE-lane fix should be authored under an SRE persona (infra-sre / core-devops), not the reviewer's Owners token. Routing this to the orchestrator (cc the task-#82 cluster — same "agent uses wrong identity" class as the force-merge / empty-PR / wrong-close incidents). Doesn't affect the fix's merit; just flag the provenance.

Verdict: the change is LGTM — but I can't formally APPROVE a PR under my own identity (Gitea blocks self-approve regardless of who wrote the commits). Needs an engineers-team / core-devops / infra-sre APPROVE for the merge gate. This comment is the substance + the authorship flag + the don't-revive-SOP_TIER_CHECK_TOKEN note.
