1. Skip ONCE on infra errors (Claude Code CLI missing/timeout/unreachable):
- run_ai_fix returns '[INFRA] ...' reasons; worker marks the PR permanently
skipped at that head SHA in fix-state (no more retry every 5 min)
- skip is recorded per {repo,pr,sha}; cleared when head SHA changes
2. Merge conflict auto-fix via Claude Code:
- mergeable=False or merge HTTP 409 now trigger run_ai_fix (prompt already
merges base + resolves conflicts) once per head SHA
- success → next tick re-checks mergeable and merges; failure → skip once
3. Discord skip notification dedupe:
- notify_skip_once(): posts '⏭️ Skipped: <reason>' exactly once per
PR+head_sha (state.notified flag); no repeated spam every cron tick
- skip reason + which PR is visible in the notification
4. State migration: legacy {repo:{pr:'sha'}} → dict form handled in _pr_entry
Verified: py_compile clean, state-helper unit tests pass (skip/fixed/notify
dedupe/legacy migration). Cron wrapper execs repo copy — no manual sync.

# Queue Worker Resiliency — Skip on Error + Conflict Auto-fix + Deduped Notify
|
|
|
|
## Goal
|
|
Make pr-queue-worker.py resilient: no infinite looping on infra errors,
|
|
auto-resolve merge conflicts via Claude Code, and notify Discord about skips
|
|
exactly once (no repeated spam).
|
|
|
|
## Scope
|
|
- `scripts/pr-queue-worker.py` only (cron worker, canonical in repo)
|
|
- State persisted in `/tmp/pr-queue-fix-state.json` (already exists)
|
|
|
|
## Changes
|
|
|
|
### A. Skip-on-error (no loop) — fix-state gains skip reasons
|
|
Current `FIX_STATE_FILE` shape: `{repo: {pr: head_sha}}` (fixed map).
|
|
Extend value to either a string SHA (fixed) or a dict for skip:
|
|
`{repo: {pr: {"fixed_sha": "<sha>", "skip_reason": "<reason>", "skip_sha": "<sha>"}}}`
|
|
- `run_ai_fix` failure kinds:
|
|
- CLI not found / not executable → **infra error** → mark skipped, notify once
|
|
- timeout → mark skipped (Claude hung), notify once
|
|
- "Claude ran but no push" → NOT infra error (Claude worked, nothing to fix)
|
|
→ allow retry next tick (cheap) OR mark fixed? — decide: keep retry (this
|
|
is often a transient "no changes needed" state, but re-running every tick
|
|
is exactly the loop user complains about) → **mark skipped too** (reason
|
|
"no changes produced"), notify once, so it stops looping. User can re-open.
|
|
- clone failed → transient (network) → retry next tick (NOT skip) — but cap:
|
|
track clone-fail attempts, after 3 → skip w/ notify.
|
|
- `already_fixed` semantics: returns True also for skip state (same SHA) so we
|
|
don't re-run OR re-notify.
|
|
- New helper `mark_skip(state, repo, pr, sha, reason)` + `get_skip(state,...)`.
|
|
|
|
### B. Merge conflict → Claude Code resolve
|
|
- When `mergeable is False` (GitHub says conflict) OR merge returns 409:
|
|
- If not already attempted at this SHA (fix-state): run `run_ai_fix` (its
|
|
prompt already includes "merge base + resolve conflicts intelligently").
|
|
- If fix returns True → continue to re-check mergeability next iteration
|
|
(head SHA changed; loop naturally proceeds).
|
|
- If fix returns False (error/no push) → mark skip + notify once.
|
|
- Prevent infinite conflict-fix loop: one AI attempt per head SHA (fix-state
|
|
`fixed_sha` covers it). If Claude pushes but conflict persists → next tick
|
|
`mergeable is False` again but fix-state SHA = old → we'd re-run. Fix:
|
|
mark conflict-resolve-attempted in state with the head SHA and the *result*
|
|
("conflict-fix-pushed" / "conflict-fix-failed"); skip re-run on same SHA.
|
|
|
|
### C. Deduped Discord notification for skips
|
|
- State file gains `notified: {repo: {pr: {"reason": sha}}}` (or embed in skip
|
|
entry: when we notify, record sha; skip notify if same sha+reason already
|
|
notified).
|
|
- Notification: one embed per skip reason, listing PRs:
|
|
`⚠️ Skipped: #19 (dependabot) — Clode Code CLI not found` — only on first
|
|
occurrence per PR+reason, not every 5-min tick.
|
|
- The full run report (flush_log) still goes out each tick — that's the
|
|
periodic status, fine. The dedupe applies to *skip-specific* notifications.
|
|
|
|
## Files touched
|
|
- `scripts/pr-queue-worker.py`
|
|
|
|
## Verification
|
|
- Unit-ish: run worker with a fake PR? Hard (needs GitHub). Instead:
|
|
- py_compile
|
|
- dry-run logic test: monkeypatch run_ai_fix to return False with
|
|
"Claude Code CLI not found" → assert mark_skip called once, second run
|
|
skips re-attempt, notify once (check state file).
|
|
- conflict path: monkeypatch mergeable False + run_ai_fix True → assert
|
|
conflict-fix-attempt recorded once.
|
|
- Live: after deploy, open a tiny conflicting PR (or use an existing one) and
|
|
watch one skip notification, then verify no repeat next tick. |
