# DocFast Code Audit — Session 43
**Date:** 2026-02-16
**Auditor:** Senior Backend Developer (automated)
**Scope:** All TypeScript files in `/opt/docfast/src/`
---
## Summary
| Severity | Count |
|----------|-------|
| CRITICAL | 3 |
| HIGH | 8 |
| MEDIUM | 10 |
| LOW | 7 |
---
## CRITICAL
### 1. XSS in Billing Success Page via API Key Display
**File:** `src/routes/billing.ts` ~line 70
**Issue:** The `escapeHtml()` function is applied to `keyInfo.key` in the HTML template, but the **same key is inserted unescaped inside a JS string** in the `onclick` handler:
```js
onclick="navigator.clipboard.writeText('${escapeHtml(keyInfo.key)}')..."
```
If an API key ever contains a single quote (unlikely with hex encoding, but the pattern is dangerous), this is XSS. More importantly, `escapeHtml` does NOT escape single quotes for JS context — `'` inside a JS string literal won't help. The key is also inserted raw into the HTML body `${escapeHtml(keyInfo.key)}` which IS properly escaped, but the JS onclick is the vector.
**Suggested fix:** Use `JSON.stringify()` for any value injected into JS context, or move the key into a `data-` attribute and read it from JS.
### 2. SSRF Bypass via DNS Rebinding in URL Convert
**File:** `src/routes/convert.ts` ~line 105-115
**Issue:** The DNS lookup happens BEFORE `page.goto()`. An attacker can use DNS rebinding: first lookup resolves to a public IP (passes check), then by the time Puppeteer fetches, DNS resolves to `127.0.0.1` or internal IPs. This is a classic TOCTOU (time-of-check-time-of-use) SSRF vulnerability.
**Suggested fix:** Configure Puppeteer to use a custom DNS resolver that blocks private IPs, or use `--host-resolver-rules` Chrome flag. Alternatively, resolve the IP yourself and pass the IP directly to Puppeteer with a Host header.
### 3. JavaScript Disabled But URL Convert Uses `networkidle0`
**File:** `src/services/browser.ts` ~line 218
**Issue:** `renderUrlPdf` calls `page.setJavaScriptEnabled(false)` then uses `waitUntil: "networkidle0"`. With JS disabled, many sites won't render properly (SPAs, dynamic content). But more critically, if the intent is security (preventing JS execution on rendered pages), the `waitUntil` setting suggests an expectation of dynamic loading that can't happen without JS. This is a **logic contradiction** that either breaks functionality or gives false security confidence.
**Suggested fix:** Either enable JS for URL rendering (with proper sandboxing/timeouts, which you already have) or change `waitUntil` to `"domcontentloaded"` and document that only static pages are supported.
---
## HIGH
### 4. Duplicate 404 Handlers
**File:** `src/index.ts` ~lines 120-170 and 172-195
**Issue:** There are TWO `app.use()` 404 catch-all handlers registered sequentially. The second one is **dead code** — Express will never reach it because the first handler always sends a response.
**Suggested fix:** Remove the second 404 handler entirely.
### 5. Webhook Signature Verification Can Be Skipped
**File:** `src/routes/billing.ts` ~line 85-95
**Issue:** When `STRIPE_WEBHOOK_SECRET` is not set, the webhook accepts **any** payload without signature verification, with only a `console.warn`. An attacker could forge webhook events to provision Pro keys or revoke existing ones. The warning uses `console.warn` instead of the structured logger.
**Suggested fix:** In production, refuse to process webhooks if `STRIPE_WEBHOOK_SECRET` is not configured. Return 500 with "Webhook not configured". At minimum, check `NODE_ENV`.
### 6. No Input Validation on Template Render Data
**File:** `src/routes/templates.ts` ~line 20
**Issue:** `req.body.data || req.body` is passed directly to `renderTemplate()` with zero validation. Template fields have `required: true` definitions but they're never enforced. Missing required fields silently produce broken HTML.
**Suggested fix:** Add validation that checks required fields from the template definition before rendering. Return 400 with specific missing fields.
### 7. Content-Type Not Checked on Markdown/URL Routes
**File:** `src/routes/convert.ts`
**Issue:** The HTML route checks `Content-Type` (~line 30) but markdown (~line 68) and URL (~line 95) routes do NOT. This inconsistency means malformed requests may parse incorrectly.
**Suggested fix:** Apply the same Content-Type check to all three routes, or extract it into a shared middleware.
### 8. `filename` Parameter Not Sanitized — Header Injection
**File:** `src/routes/convert.ts` ~lines 56, 84, 122
**Issue:** `body.filename` is inserted directly into `Content-Disposition` header:
```js
res.setHeader("Content-Disposition", `inline; filename="${filename}"`);
```
A filename containing `"` or newlines could inject headers or break the response. While Express has some protections, this is defense-in-depth.
**Suggested fix:** Sanitize filename: strip/replace `"`, `\r`, `\n`, and non-printable characters.
### 9. Verification Code Timing Attack
**File:** `src/services/verification.ts` ~line 120
**Issue:** `pending.code !== code` uses direct string comparison, which is vulnerable to timing attacks. An attacker could statistically determine correct digits.
**Suggested fix:** Use `crypto.timingSafeEqual()` with Buffer conversion for code comparison.
### 10. Usage Data Written to DB on Every Single Request
**File:** `src/middleware/usage.ts` ~line 58-65
**Issue:** Every PDF request triggers an immediate `INSERT ... ON CONFLICT UPDATE` to PostgreSQL. Under load this creates significant DB write pressure. The code even says "In-memory cache, periodically synced to PostgreSQL" but actually writes synchronously on every request.
**Suggested fix:** Batch writes — update in-memory immediately, flush to DB every 30-60 seconds or on shutdown.
### 11. Unprotected Admin Endpoints
**File:** `src/index.ts` ~lines 97-103
**Issue:** `/v1/usage` and `/v1/concurrency` are protected by `authMiddleware` but ANY valid API key (including free tier) can access them. These expose operational data that should be admin-only.
**Suggested fix:** Add an admin check (e.g., specific admin key or role-based access).
---
## MEDIUM
### 12. In-Memory Caches Can Diverge from DB
**Files:** `src/services/keys.ts`, `src/services/verification.ts`, `src/middleware/usage.ts`
**Issue:** Multiple in-memory caches (`keysCache`, `verificationsCache`, `usage` Map) are loaded on startup and updated on writes, but if a DB write fails, the in-memory state diverges. There's no reconciliation mechanism. In `keys.ts`, `createFreeKey` pushes to cache before confirming DB write succeeds (actually it awaits, so this is mostly ok, but `saveUsageEntry` in usage.ts has fire-and-forget `.catch()`).
**Suggested fix:** For critical data (keys), ensure cache is only updated after confirmed DB write. Add periodic cache refresh (e.g., every 5 min).
### 13. `verifyToken` Is Synchronous But Uses Cache
**File:** `src/services/verification.ts` ~line 47
**Issue:** `verifyToken()` is sync (used in GET `/verify` route) and relies on an in-memory cache. The DB update for `verified_at` is fire-and-forget. If the server restarts between verification and DB write, the verification is lost.
**Suggested fix:** Make the `/verify` route async and use a proper DB query.
### 14. No Request Body Size Validation Per Endpoint
**File:** `src/index.ts` ~line 73
**Issue:** Global body limit is 2MB for JSON. For HTML conversion, 2MB of complex HTML could cause Puppeteer to consume excessive memory/CPU. There's no per-route limit.
**Suggested fix:** Add tighter limits for conversion routes (e.g., 500KB) and larger for templates if needed.
### 15. Browser Pool Queue Has No Per-Key Fairness
**File:** `src/services/browser.ts`
**Issue:** The `waitingQueue` is FIFO with no per-key isolation. A single user could fill the queue and starve others. The rate limiter in `pdfRateLimit.ts` helps but a burst of requests from one key can still monopolize the queue.
**Suggested fix:** Add per-key queue limits (e.g., max 3 queued requests per key).
### 16. `console.warn` Used Instead of Logger
**Files:** `src/routes/billing.ts` ~line 88, ~line 138
**Issue:** Two places use `console.warn` instead of the structured `logger`. These won't appear in structured log output.
**Suggested fix:** Replace with `logger.warn(...)`.
### 17. No CSRF Protection on Billing Success
**File:** `src/routes/billing.ts` ~line 44
**Issue:** The `/billing/success` endpoint provisions a Pro API key based only on `session_id` query parameter. If someone obtains a valid session_id (e.g., from browser history), they can re-provision or view the key. Stripe sessions are one-time-use for payment but retrievable.
**Suggested fix:** Track which session IDs have been provisioned and reject duplicates.
### 18. Rate Limit Store Memory Leak
**File:** `src/middleware/pdfRateLimit.ts`
**Issue:** `rateLimitStore` is a Map that grows with unique API keys. `cleanupExpiredEntries()` runs every 60s, but between cleanups, a burst of requests with many keys could grow the map. The cleanup interval (`setInterval`) is never cleared on shutdown.
**Suggested fix:** Low risk in practice since keys are finite, but add a max size check or use an LRU cache.
### 19. CORS Allows `*` for Conversion Routes
**File:** `src/index.ts` ~line 60
**Issue:** `Access-Control-Allow-Origin: *` for API routes is intentional (public API), but combined with `Authorization` header, browsers will still enforce preflight. This is fine architecturally but should be documented as intentional.
**Suggested fix:** Add a code comment confirming this is intentional for the public API use case.
### 20. `trust proxy` Set to 1 Without Validation
**File:** `src/index.ts` ~line 78
**Issue:** `app.set("trust proxy", 1)` trusts the first proxy hop. If the app is ever deployed without nginx in front, rate limiting by IP becomes bypassable via `X-Forwarded-For` spoofing.
**Suggested fix:** Document the deployment requirement. Consider using `trust proxy: "loopback"` for more specificity.
### 21. Verificaton Cache Loads ALL Verifications
**File:** `src/services/verification.ts` ~line 62
**Issue:** `loadVerifications()` loads every row from the `verifications` table into memory. Over time this grows unboundedly. The 15-min cleanup only removes unverified expired ones, but verified entries persist forever in memory.
**Suggested fix:** Only load recent/unverified entries. Verified entries can be queried from DB on demand.
---
## LOW
### 22. Unused Import
**File:** `src/routes/convert.ts` ~line 3
**Issue:** `getPoolStats` is imported but never used in this file.
**Suggested fix:** Remove the unused import.
### 23. Unused Import in Test
**File:** `src/__tests__/api.test.ts` ~line 2
**Issue:** `express` is imported but never used.
**Suggested fix:** Remove.
### 24. `rejectDuplicateEmail` Uses `Function` Type
**File:** `src/routes/signup.ts` ~line 27
**Issue:** `next: Function` should be `next: NextFunction` from Express types.
**Suggested fix:** Import and use `NextFunction`.
### 25. Inconsistent Error Response Shapes
**Files:** Various routes
**Issue:** Error responses vary: some use `{ error: "..." }`, others `{ error: "...", detail: "..." }`, others `{ error: "...", limit: ..., used: ... }`. No standard error envelope.
**Suggested fix:** Define a standard error response type: `{ error: string, code?: string, details?: object }`.
### 26. `isPrivateIP` Missing IPv6 Unique Local (fc00::/7)
**File:** `src/routes/convert.ts` ~line 6-18
**Issue:** IPv6 unique local addresses (`fc00::/7`, i.e., `fc00::` to `fdff::`) are not blocked. Only link-local (`fe80::/10`) is checked. An attacker could use a `fd00::` address to bypass SSRF protection.
**Suggested fix:** Add check for `fc` and `fd` prefixes.
### 27. No Graceful Handling of DB Connection Failure at Startup
**File:** `src/index.ts` ~line start()
**Issue:** If PostgreSQL is unavailable at startup, `initDatabase()` throws and the process exits (which is correct), but there's no retry logic. In container orchestration this is fine (restart policy), but worth noting.
**Suggested fix:** Consider adding a retry with backoff for initial DB connection.
### 28. `loadKeys` Upserts Seed Keys on Every Restart
**File:** `src/services/keys.ts` ~line 28
**Issue:** Every restart re-upserts env `API_KEYS` into the DB with `ON CONFLICT DO NOTHING`. Harmless but unnecessary DB writes. Also uses `new Date().toISOString()` each time, so the `created_at` in cache won't match the DB if the key already existed.
**Suggested fix:** Check existence before upserting, or just ignore (low impact).
---
## Test Coverage Gaps
The existing test file (`src/__tests__/api.test.ts`) covers:
- ✅ Auth (missing key, invalid key)
- ✅ Health endpoint
- ✅ HTML → PDF (success + missing field)
- ✅ Markdown → PDF
- ✅ Template listing + rendering + 404
**NOT tested (critical paths missing):**
- ❌ **Signup flow** (free key creation, email verification, duplicate email rejection)
- ❌ **Recovery flow** (code generation, verification, key retrieval)
- ❌ **Email change flow**
- ❌ **Billing/Stripe** (checkout, webhook events, subscription cancellation)
- ❌ **URL → PDF** (SSRF protection, DNS rebinding, private IP blocking)
- ❌ **Usage limits** (free tier limit, pro tier limit, monthly reset)
- ❌ **Rate limiting** (per-key rate limits, concurrency limits, queue full)
- ❌ **Browser pool** (restart after N PDFs, restart after timeout, page recycling)
- ❌ **Graceful shutdown**
- ❌ **Content-Type enforcement**
- ❌ **Edge cases**: malformed JSON, oversized bodies, concurrent requests
---
## Top 5 Recommended Actions
1. **Fix DNS rebinding SSRF** (Critical #2) — resolve DNS and pass IP to Puppeteer
2. **Require webhook secret in production** (High #5) — prevent forged Stripe events
3. **Remove duplicate 404 handler** (High #4) — dead code causing confusion
4. **Add input validation to templates** (High #6) — enforce required fields
5. **Batch usage DB writes** (High #10) — reduce write pressure under load

## Session 42 — 2026-02-16 18:38 UTC (Evening Session)
- **No open bugs.** Proactive improvement session.
- **Competitive research:** Analyzed DocRaptor ($15/mo, 5 free), html2pdf.app ($9/mo = 1,000 credits), PDFShift pricing
- **CEO Decision: Pro plan limit = 2,500 PDFs/month at €9/mo**
- 2.5x more generous than html2pdf.app's $9 tier (1,000)
- Sustainable on CAX11 (~40K/day capacity)
- Competitive positioning as generous EU-hosted newcomer
- **Pro limit enforcement:** Updated `usage.ts` — Pro keys now get 429 after 2,500/mo (was 5,000 from a previous session)
- **Landing page + JSON-LD + Stripe product description all updated to "2,500 PDFs per month"**
- **Website templating refactor (owner directive):**
- Created build-time HTML templating system
- Partials: `public/partials/_nav.html`, `_footer.html`, `_styles_base.html`
- Source files: `public/src/impressum.html`, `privacy.html`, `terms.html` using `{{> partial}}` syntax
- Build script: `scripts/build-html.cjs` (CommonJS due to ESM package.json)
- Nav/footer/base styles now have single source of truth
- `npm run build:html` regenerates all subpages
- **Cleanup:** Deleted stale `index.html.backup-20260214-175429`
- **Fixed:** index.html nav logo changed from `<div>` to `<a href="/">` for consistency with subpages
- **Deployed:** Docker rebuild, container healthy, all changes live
- **Git:** Commit aab6bf3 pushed to Forgejo (resolved merge conflict with remote)
- **Verified on production:** Browser confirms "2,500 PDFs per month" on pricing, zero console errors
- **Budget:** €181.71 remaining, Revenue: €0
- **Investor Test:**
1. Trust with money? **Mostly yes** — real flows work, limits enforced
2. Data loss? **No** — backups running ✅
3. Free tier abuse? **Mitigated** — email verification required
4. Key recovery? **Yes** — recovery flow works ✅
5. False features? **Clean** — all listed features work, limits are accurate
- **Remaining blockers:** E2E Pro payment test (needs investor), CI/CD secrets
- **Status:** NOT launch-ready (user account system unchecked, CI/CD partial, E2E payment unverified)

# DocFast Backup & Disaster Recovery Procedures
## Overview
DocFast now uses BorgBackup for full disaster recovery backups. The system backs up all critical components needed to restore the service on a new server.
## What is Backed Up
- **PostgreSQL database** - Full database dump with schema and data
- **Docker volumes** - Application data and files
- **Nginx configuration** - Web server configuration
- **SSL certificates** - Let's Encrypt certificates and keys
- **Crontabs** - Scheduled tasks
- **OpenDKIM keys** - Email authentication keys
- **DocFast application files** - docker-compose.yml, .env, scripts
- **System information** - Installed packages, enabled services, disk usage
## Backup Location & Schedule
### Current Setup (Local)
- **Location**: `/opt/borg-backups/docfast`
- **Schedule**: Daily at 03:00 UTC
- **Retention**: 7 daily + 4 weekly + 3 monthly backups
- **Compression**: LZ4 (fast compression/decompression)
- **Encryption**: repokey mode (encrypted with passphrase)
### Security
- **Passphrase**: `docfast-backup-YYYY` (where YYYY is current year)
- **Key backup**: Stored in `/opt/borg-backups/docfast-key-backup.txt`
- **⚠️ IMPORTANT**: Both passphrase AND key are required for restore!
## Scripts
### Backup Script: `/opt/docfast-borg-backup.sh`
- Automated backup creation
- Runs via cron daily at 03:00 UTC
- Logs to `/var/log/docfast-backup.log`
- Auto-prunes old backups
### Restore Script: `/opt/docfast-borg-restore.sh`
- List available backups: `./docfast-borg-restore.sh list`
- Restore specific backup: `./docfast-borg-restore.sh restore docfast-YYYY-MM-DD_HHMM`
- Restore latest backup: `./docfast-borg-restore.sh restore latest`
## Manual Backup Commands
```bash
# Run backup manually
/opt/docfast-borg-backup.sh
# List all backups
export BORG_PASSPHRASE="docfast-backup-$(date +%Y)"
borg list /opt/borg-backups/docfast
# Show repository info
borg info /opt/borg-backups/docfast
# Show specific backup contents
borg list /opt/borg-backups/docfast::docfast-2026-02-15_1103
```
## Disaster Recovery Procedure
### Complete Server Rebuild
If the entire server is lost, follow these steps on a new server:
1. **Install dependencies**:
```bash
apt update && apt install -y docker.io docker-compose postgresql-16 nginx borgbackup
systemctl enable postgresql docker
```
2. **Copy backup data**:
- Transfer `/opt/borg-backups/` directory to new server
- Transfer `/opt/borg-backups/docfast-key-backup.txt`
3. **Import Borg key**:
```bash
export BORG_PASSPHRASE="docfast-backup-2026"
borg key import /opt/borg-backups/docfast /opt/borg-backups/docfast-key-backup.txt
```
4. **Restore latest backup**:
```bash
/opt/docfast-borg-restore.sh restore latest
```
5. **Follow manual restore steps** (shown by restore script):
- Stop services
- Restore database
- Restore configuration files
- Set permissions
- Start services
### Database-Only Recovery
If only the database needs restoration:
```bash
# Stop DocFast
cd /opt/docfast && docker-compose down
# Restore database
export BORG_PASSPHRASE="docfast-backup-$(date +%Y)"
cd /tmp
borg extract /opt/borg-backups/docfast::docfast-YYYY-MM-DD_HHMM
sudo -u postgres dropdb docfast
sudo -u postgres createdb -O docfast docfast
export PGPASSFILE="/root/.pgpass"
pg_restore -d docfast /tmp/tmp/docfast-backup-*/docfast-db.dump
# Restart DocFast
cd /opt/docfast && docker-compose up -d
```
## Migration to Off-Site Storage
### Option 1: Hetzner Storage Box (Recommended)
Manual setup required (Hetzner Storage Box API not available):
1. **Purchase Hetzner Storage Box**
- Minimum 10GB size
- Enable SSH access in Hetzner Console
2. **Configure SSH access**:
```bash
# Generate SSH key for storage box
ssh-keygen -t ed25519 -f /root/.ssh/hetzner-storage-box
# Add public key to storage box in Hetzner Console
cat /root/.ssh/hetzner-storage-box.pub
```
3. **Update backup script**:
Change `BORG_REPO` in `/opt/docfast-borg-backup.sh`:
```bash
BORG_REPO="ssh://uXXXXXX@uXXXXXX.your-storagebox.de:23/./docfast-backups"
```
4. **Initialize remote repository**:
```bash
export BORG_PASSPHRASE="docfast-backup-$(date +%Y)"
borg init --encryption=repokey ssh://uXXXXXX@uXXXXXX.your-storagebox.de:23/./docfast-backups
```
### Option 2: AWS S3/Glacier
Use rclone + borg for S3 storage (requires investor approval for AWS costs).
## Monitoring & Maintenance
### Check Backup Status
```bash
# View recent backup logs
tail -f /var/log/docfast-backup.log
# Check repository size and stats
export BORG_PASSPHRASE="docfast-backup-$(date +%Y)"
borg info /opt/borg-backups/docfast
```
### Manual Cleanup
```bash
# Prune old backups manually
borg prune --keep-daily 7 --keep-weekly 4 --keep-monthly 3 /opt/borg-backups/docfast
# Compact repository
borg compact /opt/borg-backups/docfast
```
### Repository Health Check
```bash
# Check repository consistency
borg check --verify-data /opt/borg-backups/docfast
```
## Important Notes
1. **Test restores regularly** - Run restore test monthly
2. **Monitor backup logs** - Check for failures in `/var/log/docfast-backup.log`
3. **Keep key safe** - Store `/opt/borg-backups/docfast-key-backup.txt` securely off-site
4. **Update passphrase annually** - Change to new year format when year changes
5. **Local storage limit** - Current server has ~19GB available, monitor usage
## Migration Timeline
- **Immediate**: Local BorgBackup operational (✅ Complete)
- **Phase 2**: Off-site storage setup (requires Storage Box purchase or AWS approval)
- **Phase 3**: Automated off-site testing and monitoring

# DocFast CI/CD Pipeline Setup - COMPLETED ✅
## What Was Implemented
### ✅ Forgejo Actions Workflow
- **File**: `.forgejo/workflows/deploy.yml`
- **Trigger**: Push to `main` branch
- **Process**:
1. SSH to production server (167.235.156.214)
2. Pull latest code from git
3. Tag current Docker image for rollback (`rollback-YYYYMMDD-HHMMSS`)
4. Build new Docker image with `--no-cache`
5. Stop current services (30s graceful timeout)
6. Start new services with `docker compose up -d`
7. Health check at `http://127.0.0.1:3100/health` (30 attempts, 5s intervals)
8. **Auto-rollback** if health check fails
9. Cleanup old rollback images (keeps last 5)
### ✅ Rollback Mechanism
- **Automatic**: Built into the deployment workflow
- **Manual Script**: `scripts/rollback.sh` for emergency use
- **Image Tagging**: Previous images tagged with timestamps
- **Auto-cleanup**: Removes old rollback images automatically
### ✅ Documentation
- **`DEPLOYMENT.md`**: Complete deployment guide
- **`CI-CD-SETUP-COMPLETE.md`**: This summary
- **Inline comments**: Detailed workflow documentation
### ✅ Git Integration
- Repository: `git@git.cloonar.com:openclawd/docfast.git`
- SSH access configured with key: `/home/openclaw/.ssh/docfast`
- All CI/CD files committed and pushed successfully
## What Needs Manual Setup (5 minutes)
### 🔧 Repository Secrets
Go to: https://git.cloonar.com/openclawd/docfast/settings/actions/secrets
Add these 3 secrets:
1. **SERVER_HOST**: `167.235.156.214`
2. **SERVER_USER**: `root`
3. **SSH_PRIVATE_KEY**: (copy content from `/home/openclaw/.ssh/docfast`)
### 🧪 Test the Pipeline
1. Once secrets are added, push any change to main branch
2. Check Actions tab: https://git.cloonar.com/openclawd/docfast/actions
3. Watch deployment progress
4. Verify with: `curl http://127.0.0.1:3100/health`
## How to Trigger Deployments
- **Automatic**: Any push to `main` branch
- **Manual**: Push a trivial change (already prepared: VERSION file)
## How to Rollback
### Automatic Rollback
- Happens automatically if new deployment fails health checks
- No manual intervention required
### Manual Rollback Options
```bash
# Option 1: Use the rollback script
ssh root@167.235.156.214
cd /root/docfast
./scripts/rollback.sh
# Option 2: Manual Docker commands
ssh root@167.235.156.214
docker compose down
docker images | grep rollback # Find latest rollback image
docker tag docfast-docfast:rollback-YYYYMMDD-HHMMSS docfast-docfast:latest
docker compose up -d
```
## Monitoring Commands
```bash
# Health check
curl http://127.0.0.1:3100/health
# Service status
docker compose ps
# View logs
docker compose logs -f docfast
# Check rollback images available
docker images | grep docfast-docfast
```
## Files Added/Modified
```
.forgejo/workflows/deploy.yml # Main deployment workflow
scripts/rollback.sh # Emergency rollback script
scripts/setup-secrets.sh # Helper script (API had auth issues)
DEPLOYMENT.md # Deployment documentation
CI-CD-SETUP-COMPLETE.md # This summary
VERSION # Test file for pipeline testing
```
## Next Steps
1. **Set up secrets** in Forgejo (5 minutes)
2. **Test deployment** by making a small change
3. **Verify** the health check endpoint works
4. **Document** any environment-specific adjustments needed
## Success Criteria ✅
- [x] Forgejo Actions available and configured
- [x] Deployment workflow created and tested (syntax)
- [x] Rollback mechanism implemented (automatic + manual)
- [x] Health check integration (`/health` endpoint)
- [x] Git repository integration working
- [x] Documentation complete
- [x] Test change ready for pipeline verification
**Ready for production use once secrets are configured!** 🚀

# DocFast CI/CD Deployment
This repository uses Forgejo Actions for automated deployment to production.
## Setup Instructions
### 1. Repository Secrets
Go to repository settings → Actions → Secrets and add these secrets:
- **SERVER_HOST**: `167.235.156.214`
- **SERVER_USER**: `root`
- **SSH_PRIVATE_KEY**: The private SSH key content from `/home/openclaw/.ssh/docfast`
### 2. How Deployment Works
**Trigger**: Push to `main` branch
**Process**:
1. SSH to production server
2. Pull latest code from git
3. Tag current Docker image for rollback
4. Build new Docker image
5. Stop current services
6. Start new services
7. Health check at `http://127.0.0.1:3100/health`
8. Rollback automatically if health check fails
### 3. Rollback Procedure
**Automatic Rollback**:
- Happens automatically if deployment fails health checks
- Reverts to the previously tagged image
**Manual Rollback**:
```bash
# On the production server
cd /root/docfast
./scripts/rollback.sh
```
**Emergency Rollback via SSH**:
```bash
ssh root@167.235.156.214
cd /root/docfast
docker compose down
docker tag docfast-docfast:rollback-YYYYMMDD-HHMMSS docfast-docfast:latest
docker compose up -d
```
### 4. Monitoring
- **Health Check**: `curl http://127.0.0.1:3100/health`
- **Service Status**: `docker compose ps`
- **Logs**: `docker compose logs -f`
### 5. File Structure
```
.forgejo/workflows/deploy.yml # Main deployment workflow
scripts/rollback.sh # Manual rollback script
scripts/setup-secrets.sh # Helper for setting up secrets
DEPLOYMENT.md # This documentation
```
### 6. Testing the Pipeline
1. Make a small change (e.g., bump version comment)
2. Commit and push to main branch
3. Check Actions tab in Forgejo to see deployment progress
4. Verify service is running with `curl http://127.0.0.1:3100/health`
## Troubleshooting
- **SSH Issues**: Ensure SSH key is properly added to secrets
- **Docker Build Issues**: Check server has enough disk space and memory
- **Health Check Fails**: Check if service is binding to correct port (3100)
- **Permission Issues**: Ensure user has Docker privileges on server

# DocFast Bugs
## Open
### BUG-030: Email change backend not implemented
- **Severity:** High
- **Found:** 2026-02-14 QA session
- **Description:** Frontend UI for email change is deployed (modal, form, JS handlers), but no backend routes exist. Frontend calls `/v1/email-change` and `/v1/email-change/verify` which return 404.
- **Impact:** Users see "Change Email" link in footer but the feature doesn't work.
- **Fix:** Implement `src/routes/email-change.ts` with verification code flow similar to signup/recover.
### BUG-031: Stray file "\001@" in repository
- **Severity:** Low
- **Found:** 2026-02-14
- **Description:** An accidental file named `\001@` was committed to the repo.
- **Fix:** `git rm "\001@"` and commit.
### BUG-032: Swagger UI content not rendered via web_fetch
- **Severity:** Low (cosmetic)
- **Found:** 2026-02-14
- **Description:** /docs page loads (200) and has swagger-ui assets, but content is JS-rendered so web_fetch can't verify full render. Needs browser-based QA for full verification.
## Fixed
(none yet - this is first QA session)

# DocFast Decisions Log
## 2026-02-14: Mandatory QA After Every Deployment
**Rule:** Every deployment MUST be followed by a full QA session. No exceptions.
**QA Checklist:**
- Landing page loads, zero console errors
- Signup flow works (email verification)
- Key recovery flow works
- Email change flow works (when backend is implemented)
- Swagger UI loads at /docs
- API endpoints work (HTML→PDF, Markdown→PDF, URL→PDF)
- Health endpoint returns ok
- All previous features still working
**Rationale:** Code was deployed to production without verification multiple times, leading to broken features being live. QA catches regressions before users do.
## 2026-02-14: Code Must Be Committed Before Deployment
Changes were found uncommitted on the production server. All code changes must be committed and pushed to Forgejo before deploying.

# DocFast Infrastructure Guide
Complete disaster recovery and deployment guide for DocFast.
## Quick Start (New Server Deployment)
### 1. Prerequisites
- Fresh Ubuntu 24.04 LTS server
- Root access
- Domain name pointing to server IP
- Stripe account with webhook configured
### 2. Automated Setup
```bash
# Clone the repository
git clone ssh://forgejo@git.cloonar.com/openclawd/docfast.git
cd docfast/infrastructure
# Run the setup script as root
chmod +x setup.sh
./setup.sh
# Follow the post-setup instructions
```
### 3. Manual Configuration Required
After running `setup.sh`, complete these manual steps:
#### SSL Certificate
```bash
certbot --nginx -d docfast.dev -d www.docfast.dev
```
#### DKIM DNS Record
Add this TXT record to your DNS:
```
mail._domainkey.docfast.dev
```
Get the value from: `/etc/opendkim/keys/docfast.dev/mail.txt`
#### Environment Variables
```bash
cd /opt/docfast
cp infrastructure/.env.template .env
# Edit .env with real values
```
#### Start the Application
```bash
cd /opt/docfast
cp infrastructure/docker-compose.yml .
docker-compose up -d
```
## Complete Manual Setup (Step by Step)
If the automated script fails or you prefer manual setup:
### System Packages
```bash
apt update && apt upgrade -y
apt install -y nginx postfix opendkim opendkim-tools certbot \
python3-certbot-nginx ufw docker.io docker-compose-plugin \
git sqlite3 postgresql postgresql-contrib
```
### Firewall Configuration
```bash
ufw --force enable
ufw default deny incoming
ufw default allow outgoing
ufw allow ssh
ufw allow 80/tcp
ufw allow 443/tcp
ufw allow from 172.16.0.0/12 to any port 25 comment "Docker SMTP relay"
ufw allow from 172.16.0.0/12 to any port 5432 comment "Docker PostgreSQL"
```
### PostgreSQL Setup
```bash
sudo -u postgres createuser -D -A -P docfast
sudo -u postgres createdb -O docfast docfast
# Edit /etc/postgresql/16/main/postgresql.conf
echo "listen_addresses = '*'" >> /etc/postgresql/16/main/postgresql.conf
# Edit /etc/postgresql/16/main/pg_hba.conf
echo "host docfast docfast 172.17.0.0/16 md5" >> /etc/postgresql/16/main/pg_hba.conf
echo "host docfast docfast 172.18.0.0/16 md5" >> /etc/postgresql/16/main/pg_hba.conf
systemctl restart postgresql
```
### Nginx Configuration
```bash
cp nginx/docfast.dev /etc/nginx/sites-available/
ln -s /etc/nginx/sites-available/docfast.dev /etc/nginx/sites-enabled/
rm /etc/nginx/sites-enabled/default
nginx -t
systemctl reload nginx
```
### Postfix & OpenDKIM
```bash
cp postfix/main.cf /etc/postfix/
cp postfix/opendkim.conf /etc/opendkim.conf
cp postfix/TrustedHosts /etc/opendkim/
# Generate DKIM keys
mkdir -p /etc/opendkim/keys/docfast.dev
cd /etc/opendkim/keys/docfast.dev
opendkim-genkey -s mail -d docfast.dev
chown opendkim:opendkim mail.private mail.txt
chmod 600 mail.private
systemctl restart postfix opendkim
```
### Application Deployment
```bash
useradd -r -m -s /bin/bash docfast
usermod -aG docker docfast
mkdir -p /opt/docfast
chown docfast:docfast /opt/docfast
cd /opt/docfast
# Copy your source code here
cp infrastructure/docker-compose.yml .
cp infrastructure/.env.template .env
# Edit .env with real values
docker-compose up -d
```
### Backup System
```bash
# Install BorgBackup
apt install -y borgbackup
# Create backup directories
mkdir -p /opt/docfast-backups /opt/borg-backups
# Copy backup scripts
cp scripts/docfast-backup.sh /opt/
cp scripts/borg-backup.sh /opt/
cp scripts/borg-restore.sh /opt/
cp scripts/rollback.sh /opt/
chmod +x /opt/docfast-backup.sh /opt/borg-backup.sh /opt/borg-restore.sh /opt/rollback.sh
# Add to root crontab
echo "0 */6 * * * /opt/docfast-backup.sh >> /var/log/docfast-backup.log 2>&1" | crontab -
echo "0 3 * * * /opt/borg-backup.sh >> /var/log/borg-backup.log 2>&1" | crontab -
```
## Backup Strategy
DocFast uses a two-tier backup strategy for comprehensive data protection:
### 1. SQLite Database Backups (Every 6 hours)
- **Script**: `/opt/docfast-backup.sh`
- **Frequency**: Every 6 hours via cron
- **Retention**: 7 days of backups (28 files), plus 4 weekly copies
- **Storage**: `/opt/docfast-backups/`
- **Method**: SQLite `.backup` command with integrity verification
### 2. Complete System Backups (Daily)
- **Script**: `/opt/borg-backup.sh`
- **Frequency**: Daily at 03:00 UTC via cron
- **Retention**: 7 daily + 4 weekly + 3 monthly
- **Storage**: `/opt/borg-backups/docfast`
- **Includes**:
- PostgreSQL database dump
- Docker volumes (complete application data)
- Nginx configuration
- SSL certificates (Let's Encrypt)
- OpenDKIM keys and configuration
- Cron jobs and system configurations
- Application files (.env, docker-compose.yml)
- System information (packages, services)
### Backup Management Commands
```bash
# List available Borg backups
/opt/borg-restore.sh list
# Restore from latest backup (creates restore directory)
/opt/borg-restore.sh restore latest
# Restore from specific backup
/opt/borg-restore.sh restore docfast-2026-02-15_0300
# Quick rollback (Docker image only)
/opt/rollback.sh
```
## Disaster Recovery Procedures
### Complete Server Failure
1. **Provision new server** with same OS version
2. **Run setup script** from this repository
3. **Restore DNS** records to point to new server
4. **Copy backups** from off-site storage to `/opt/docfast-backups/`
5. **Restore database**:
```bash
docker-compose down
docker volume rm docfast_docfast-data
docker volume create docfast_docfast-data
cp /opt/docfast-backups/docfast-weekly-LATEST.db \
/var/lib/docker/volumes/docfast_docfast-data/_data/docfast.db
docker-compose up -d
```
6. **Verify SSL certificates** with `certbot certificates`
7. **Test email delivery** and DKIM signing
### Database Corruption
```bash
cd /opt/docfast
docker-compose down
# Find latest good backup
ls -la /opt/docfast-backups/
# Restore from backup
cp /opt/docfast-backups/docfast-daily-LATEST.db \
/var/lib/docker/volumes/docfast_docfast-data/_data/docfast.db
docker-compose up -d
```
### Email Delivery Issues
Check DKIM setup:
```bash
# Verify DKIM key is readable
sudo -u opendkim cat /etc/opendkim/keys/docfast.dev/mail.private
# Check OpenDKIM is signing
tail -f /var/log/mail.log
# Test email sending
echo "Test email" | mail -s "Test" test@example.com
```
### SSL Certificate Issues
```bash
# Check certificate status
certbot certificates
# Renew if needed
certbot renew --dry-run
certbot renew
# Fix nginx config if needed
nginx -t
systemctl reload nginx
```
## Monitoring & Maintenance
### Daily Checks
- [ ] Application health: `curl https://docfast.dev/health`
- [ ] Docker containers: `docker ps`
- [ ] Disk space: `df -h`
- [ ] Backup status: `ls -la /opt/docfast-backups/`
### Weekly Checks
- [ ] SSL certificate expiry: `certbot certificates`
- [ ] Email delivery test
- [ ] System updates: `apt list --upgradable`
- [ ] Log rotation: `du -sh /var/log/`
### Monthly Tasks
- [ ] Review backup retention
- [ ] Update system packages
- [ ] Review firewall rules: `ufw status`
- [ ] Check for failed login attempts: `grep "Failed password" /var/log/auth.log`
## Environment Variables Reference
| Variable | Required | Description | Example |
|----------|----------|-------------|---------|
| `STRIPE_SECRET_KEY` | ✅ | Stripe API secret key | `sk_live_...` |
| `STRIPE_WEBHOOK_SECRET` | ✅ | Stripe webhook endpoint secret | `whsec_...` |
| `BASE_URL` | ✅ | Application base URL | `https://docfast.dev` |
| `API_KEYS` | ✅ | Comma-separated API keys | `key1,key2,key3` |
| `PRO_KEYS` | ✅ | Comma-separated pro API keys | `prokey1,prokey2` |
| `DATABASE_PASSWORD` | ✅ | PostgreSQL password | `secure_password_123` |
## DNS Records Required
| Type | Name | Value | TTL |
|------|------|-------|-----|
| A | docfast.dev | SERVER_IP | 300 |
| A | www.docfast.dev | SERVER_IP | 300 |
| TXT | mail._domainkey.docfast.dev | DKIM_PUBLIC_KEY | 300 |
| MX | docfast.dev | docfast.dev | 300 |
| TXT | docfast.dev | v=spf1 mx ~all | 300 |
## Stripe Configuration
Required webhook events:
- `checkout.session.completed`
- `invoice.payment_succeeded`
- `customer.subscription.created`
- `customer.subscription.updated`
- `customer.subscription.deleted`
Webhook URL: `https://docfast.dev/api/stripe/webhook`
## Security Considerations
- Server runs on non-standard SSH port (change from 22)
- Fail2ban recommended for brute force protection
- Regular security updates via unattended-upgrades
- Database backups encrypted at rest
- API keys rotated regularly
- Monitor application logs for suspicious activity
## Troubleshooting
### Common Issues
**Container won't start**: Check logs with `docker-compose logs -f`
**Database connection errors**: Verify PostgreSQL is running and Docker networks are configured
**Email not sending**: Check postfix logs: `tail -f /var/log/mail.log`
**SSL certificate errors**: Verify domain DNS and run `certbot --nginx`
**High memory usage**: Monitor with `docker stats` and adjust container limits
### Log Locations
- Application: `docker-compose logs`
- Nginx: `/var/log/nginx/`
- Postfix: `/var/log/mail.log`
- System: `/var/log/syslog`
- Backups: `/var/log/docfast-backup.log`

# DocFast Sessions Log
## 2026-02-14 22:14 UTC — Deployment + QA Session
**Trigger:** Latest code changes (Swagger UI, key recovery UI, email change) were not deployed despite being in the working tree.
**Actions:**
1. SSH'd into server (167.235.156.214)
2. Found uncommitted changes in working tree (email change UI, Swagger UI, key recovery link)
3. Committed all changes: `d859e9f` — "feat: email change UI, Swagger UI improvements, key recovery link on landing page"
4. Pushed to Forgejo (openclawd/docfast)
5. Rebuilt container with `docker compose build --no-cache`
6. Restarted: `docker compose up -d`
7. Verified server healthy: 15-page browser pool, version 0.2.1
**QA Results:**
| Test | Result |
|------|--------|
| Landing page loads | ✅ 200 OK |
| Key recovery link on landing | ✅ Present |
| Email change link in footer | ✅ Present |
| Swagger UI at /docs | ✅ 200 OK |
| Signup endpoint | ✅ Works (verification_required) |
| Key recovery endpoint | ✅ Works (recovery_sent) |
| Email change backend | ❌ NOT IMPLEMENTED (BUG-030) |
| HTML→PDF conversion | ✅ Valid PDF |
| Markdown→PDF conversion | ✅ Valid PDF |
| URL→PDF conversion | ✅ Valid PDF |
| Health endpoint | ✅ Pool: 15 pages, 0 active |
| Browser pool | ✅ 1 browser × 15 pages |
**Bugs Found:**
- BUG-030: Email change backend not implemented (frontend-only)
- BUG-031: Stray `\001@` file in repo
- BUG-032: Swagger UI needs browser QA for full verification
**Note:** Browser-based QA not available (openclaw browser service unreachable). Console error check, mobile responsive test, and full Swagger UI render verification deferred.
