## BUG-075: Database Connection Pool Does Not Handle PgBouncer Failover - **Date:** 2026-02-18 14:05 UTC - **Severity:** CRITICAL - **Issue:** When a PgBouncer pooler instance goes down (K8s node failure), pods keep stale TCP connections and get "no available server" errors. App never reconnects — all PDF conversions fail until manual pod restart. - **Root cause:** `pg.Pool` in `src/services/db.ts` has no keepAlive, no connectionTimeoutMillis, no retry logic. No mechanism to detect or recover from dead connections. - **Impact:** Complete service outage for pods connected to failed pooler. Violates HA requirements. - **Fix needed:** (1) Enable TCP keepalive + connection timeout, (2) Add retry with backoff for transient DB errors, (3) Health check must fail when DB is unreachable (already partially done but needs timeout), (4) Verify recovery without pod restart - **Status:** ✅ FIXED (PROPERLY) — v0.2.6 fix was insufficient (retried on same dead pool connections). Commit 95ca101 fixes the real issue: `queryWithRetry` now uses explicit client checkout and calls `client.release(true)` to DESTROY dead connections on transient errors, forcing fresh TCP connections on retry. `connectWithRetry` validates with `SELECT 1` before returning. `idleTimeoutMillis` reduced to 10s. Health check destroys bad connections. **Verified on staging:** killed a pooler pod, 15/15 health checks passed, zero app restarts. ## BUG-074: Email Broken on K3s Production — SMTP Misconfigured - **Date:** 2026-02-18 13:00 UTC - **Severity:** CRITICAL - **Issue:** After K3s migration, production pods used old Docker code connecting to `host.docker.internal:25` (non-existent in K3s). The SMTP fix (commit 0902e1e) was on staging but not deployed to production. - **Root cause:** Three issues: (1) Production image at old commit without SMTP env var support, (2) K3s secrets pointed to mail.cloonar.com which rejected K3s worker IPs, (3) Old server Postfix only listened on localhost + Docker bridge, not public IP - **Fix applied:** 1. Updated K8s SMTP secrets to use old server (167.235.156.214) as relay (has DKIM for docfast.dev) 2. Added K3s worker IPs to old server's Postfix `mynetworks` and UFW rules (port 25) 3. Made Postfix listen on public IP (`inet_interfaces`) 4. Tagged v0.2.3 to deploy SMTP fix to production 5. Restarted all pods to pick up new secrets - **Verification:** `Verification email sent` confirmed in production logs - **Status:** ✅ FIXED ## BUG-073: Staging Landing Page Shows Wrong Pro Plan Quota (2,500 vs 5,000) - **Date:** 2026-02-18 13:05 UTC - **Severity:** MEDIUM - **Environment:** Staging (https://staging.docfast.dev) - **Issue:** Staging landing page shows Pro plan as "2,500 PDFs per month" but production also shows "2,500 PDFs per month". Previous bugs (BUG-045, BUG-057) referenced 5,000 and 10,000 PDFs. The Stripe checkout page says "5,000 PDF conversions per month". There is a mismatch between what the landing page advertises (2,500) and what Stripe checkout says (5,000). - **Impact:** Customer confusion — they see 2,500 on the pricing page but 5,000 on the checkout page - **Fix:** Align landing page and Stripe product description to the same number - **Status:** OPEN --- ## BUG-072: Production Outage — UFW+Docker Conflict + Dual Deployment - **Date:** 2026-02-18 ~08:00 UTC - **Severity:** CRITICAL - **Duration:** Unknown start time → fixed 08:04 UTC - **Symptoms:** App container stuck in restart loop, unable to reach PostgreSQL. `ENETUNREACH 172.17.0.1:5432` - **Root causes:** 1. UFW injected DROP rules into Docker's DOCKER iptables chain, blocking container-to-host networking 2. A systemd service (`docfast.service`) running a separate Node.js process from `/opt/docfast` was binding port 3100, preventing Docker container from starting after fix - **Fix applied:** - Removed iptables DROP rules from DOCKER chain - Stopped and disabled `docfast.service` systemd unit - Changed DATABASE_HOST from `172.17.0.1` to `host.docker.internal` in docker-compose.yml - Full `docker compose down && up -d` — container healthy - **Permanent fix:** DevOps agent dispatched to properly resolve ufw+Docker conflict and remove dual deployment - **Status:** FIXED (immediate), permanent fix in progress --- # DocFast QA Report — 2026-02-15 **Tester:** QA Bot (automated) **Version:** 0.2.1 **URL:** https://docfast.dev --- ## Bug Fix Verification ### ✅ BUG-032: Mobile Terminal Gap — FIXED - Tested at 375×812 viewport - `.code-section` uses `display: flex; flex-direction: column` - Gap between `.code-header` and `.code-block`: **0px** ✅ - Screenshot confirms no visible gap ### ✅ BUG-035: STRIPE_WEBHOOK_SECRET Deployed — VERIFIED - Pro "Get Started →" button redirects to Stripe checkout - Stripe page shows "Subscribe to DocFast Pro" at $9.00/mo - Merchant: Cloonar Technologies GmbH - Stripe checkout fully functional ### ⚠️ BUG-037: Webhook product_id Filter — CANNOT VERIFY - Cannot test webhook handler directly (requires Stripe event) - Stripe checkout page loads correctly, suggesting integration is wired up - **Needs manual verification** with a test Stripe webhook event --- ## Test Results ### 1. Console Errors — ✅ PASS - Zero JS errors in browser console - Zero warnings ### 2. Mobile Terminal Gap — ✅ PASS - 375×812 viewport, zero gap between terminal header and body - Flexbox layout confirmed via computed styles ### 3. Signup Flow — ✅ PASS - "Get Free API Key" button opens modal - Email input works, "Generate API Key →" submits - Verification code screen appears with correct email displayed - API: `POST /v1/signup/free` returns `{"status":"verification_required"}` - API: `POST /v1/signup/verify` with wrong code returns `{"error":"Invalid verification code."}` ### 4. Pro Checkout — ✅ PASS - "Get Started →" redirects to Stripe checkout - Correct product: DocFast Pro, $9.00/month - Full Stripe payment form (card, billing address, etc.) ### 5. /docs Page — ✅ PASS - Swagger UI loads with full API documentation - All endpoint groups visible: Conversion, Templates, Account, Billing, System - OpenAPI spec accessible at `/openapi.json` ### 6. Health Endpoint — ⚠️ PARTIAL PASS - `GET /health` returns `{"status":"ok","version":"0.2.1",...}` - Pool stats included (size, active, available, queue depth) - **Issue: No PostgreSQL connection info in health response** - No `database` or `postgres` field - No DB version reported - Health check only covers the browser pool, not the database - **Severity: LOW** — DB issues would surface as auth/signup failures, but health endpoint should ideally confirm DB connectivity ### 7. HTML→PDF Generation — ⏭️ SKIPPED - Cannot complete without a valid API key (email verification requires receiving actual email) - Signup works, but test environment can't receive verification emails at `@test.docfast.dev` ### 8. Error Handling — ✅ PASS - Bad API key → `403 {"error":"Invalid API key"}` ✅ - No API key → `401 {"error":"Missing API key. Use: Authorization: Bearer or X-API-Key: "}` ✅ - Missing params with bad key → `403` (auth checked first, correct behavior) ✅ - **Cannot test missing params with valid key** (see #7) --- ## New Issues Found ### BUG-038: Health Endpoint Missing Database Status - **Severity:** LOW - **Endpoint:** `GET /health` - **Expected:** Health response should include PostgreSQL connection status and version - **Actual:** Only returns browser pool stats, no database info - **Impact:** Monitoring blind spot — DB could be down but /health reports "ok" ### BUG-039: API Signup Endpoint Mismatch in Docs - **Severity:** INFO - **Details:** The docs page references `POST /v1/signup/free` but the original test spec listed `POST /v1/auth/signup` — this is just a documentation/spec mismatch in the test plan, not a bug in the app itself --- ## Summary | Test | Result | |------|--------| | Console errors | ✅ PASS (0 errors) | | Mobile terminal gap | ✅ PASS (0px gap) | | Signup flow | ✅ PASS | | Pro checkout → Stripe | ✅ PASS | | /docs page | ✅ PASS | | Health endpoint | ⚠️ PARTIAL (no DB status) | | PDF generation | ⏭️ SKIPPED (no valid key) | | Error handling | ✅ PASS | **Overall: 5 PASS, 1 PARTIAL, 1 SKIPPED, 1 N/A** The three reported bugs (BUG-032, BUG-035, BUG-037) are verified fixed (032, 035) or plausibly fixed (037 — needs webhook test). One new low-severity issue found (health endpoint missing DB status). --- # DocFast QA Full Regression — 2026-02-16 **Tester:** QA Bot (harsh mode) **Trigger:** Container was found DOWN this morning, restarted **URL:** https://docfast.dev **Browser:** Chrome (OpenClaw profile) **Tests:** Full regression suite --- ## BUG-050: Broken MX Record Causes Email Delivery Failures — CRITICAL - **Severity:** CRITICAL - **Issue:** MX record for docfast.dev resolves to `mail.cloonar.com.docfast.dev` (non-existent) instead of a valid mail server. This is a relative hostname in DNS that got appended to the zone. - **Impact:** Any mail server doing sender address verification (like cloonar.com) rejects our emails. Customer #370 cannot receive verification codes. This likely affects other recipients too. - **Root cause:** MX DNS record was entered as `mail.cloonar.com` without trailing dot, so Hetzner DNS appended `.docfast.dev` - **Fix needed:** Investor must fix MX record in Hetzner DNS console: - **Option A (recommended):** Set MX to `docfast.dev.` (point to own server, since Postfix runs there) - **Option B:** Delete the broken MX record entirely (servers will fall back to A record) - **Workaround applied:** Postfix now accepts local mail for noreply@docfast.dev (mydestination + virtual alias), but this only helps if the remote server can reach us — which it can't due to broken MX. - **Status:** OPEN — requires investor DNS action - **Discovered:** 2026-02-17 Session 48 --- ## Test Results Summary | Test Category | Status | Details | |--------------|--------|---------| | Site Load + Console | ✅ PASS | ZERO JS errors (requirement met) | | Signup Flow | ✅ PASS | Email → verification screen works | | Pro → Stripe | ✅ PASS | Redirect + checkout form working | | /docs Swagger UI | ✅ PASS | Full API documentation loads | | Mobile Responsive | ✅ PASS | 375×812 layout perfect | | /health endpoint | ✅ PASS | Database status included | | API Tests | ✅ PASS | All endpoints working | | Error Handling | ✅ PASS | 401/403 responses correct | **Overall Result: ALL TESTS PASS ✅** --- ## Detailed Test Results ### 1.
