From b97eaeea4c0ffc9b145494230e074d48b1ae89c5 Mon Sep 17 00:00:00 2001 From: unclecode Date: Fri, 17 Oct 2025 20:38:39 +0800 Subject: [PATCH 1/8] feat(docker): implement smart browser pool with 10x memory efficiency MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major refactoring to eliminate memory leaks and enable high-scale crawling: - **Smart 3-Tier Browser Pool**: - Permanent browser (always-ready default config) - Hot pool (configs used 3+ times, longer TTL) - Cold pool (new/rare configs, short TTL) - Auto-promotion: cold → hot after 3 uses - 100% pool reuse achieved in tests - **Container-Aware Memory Detection**: - Read cgroup v1/v2 memory limits (not host metrics) - Accurate memory pressure detection in Docker - Memory-based browser creation blocking - **Adaptive Janitor**: - Dynamic cleanup intervals (10s/30s/60s based on memory) - Tiered TTLs: cold 30-300s, hot 120-600s - Aggressive cleanup at high memory pressure - **Unified Pool Usage**: - All endpoints now use pool (/html, /screenshot, /pdf, /execute_js, /md, /llm) - Fixed config signature mismatch (permanent browser matches endpoints) - get_default_browser_config() helper for consistency - **Configuration**: - Reduced idle_ttl: 1800s → 300s (30min → 5min) - Fixed port: 11234 → 11235 (match Gunicorn) **Performance Results** (from stress tests): - Memory: 10x reduction (500-700MB × N → 270MB permanent) - Latency: 30-50x faster (<100ms pool hits vs 3-5s startup) - Reuse: 100% for default config, 60%+ for variants - Capacity: 100+ concurrent requests (vs ~20 before) - Leak: 0 MB/cycle (stable across tests) **Test Infrastructure**: - 7-phase sequential test suite (tests/) - Docker stats integration + log analysis - Pool promotion verification - Memory leak detection - Full endpoint coverage Fixes memory issues reported in production deployments. --- deploy/docker/STRESS_TEST_PIPELINE.md | 241 +++++++++++++++++ deploy/docker/api.py | 66 +++-- deploy/docker/config.yml | 4 +- deploy/docker/crawler_pool.py | 166 +++++++++--- deploy/docker/server.py | 83 +++--- deploy/docker/tests/requirements.txt | 2 + deploy/docker/tests/test_1_basic.py | 138 ++++++++++ deploy/docker/tests/test_2_memory.py | 205 ++++++++++++++ deploy/docker/tests/test_3_pool.py | 229 ++++++++++++++++ deploy/docker/tests/test_4_concurrent.py | 236 ++++++++++++++++ deploy/docker/tests/test_5_pool_stress.py | 267 +++++++++++++++++++ deploy/docker/tests/test_6_multi_endpoint.py | 234 ++++++++++++++++ deploy/docker/tests/test_7_cleanup.py | 199 ++++++++++++++ deploy/docker/utils.py | 27 +- 14 files changed, 1979 insertions(+), 118 deletions(-) create mode 100644 deploy/docker/STRESS_TEST_PIPELINE.md create mode 100644 deploy/docker/tests/requirements.txt create mode 100755 deploy/docker/tests/test_1_basic.py create mode 100755 deploy/docker/tests/test_2_memory.py create mode 100755 deploy/docker/tests/test_3_pool.py create mode 100755 deploy/docker/tests/test_4_concurrent.py create mode 100755 deploy/docker/tests/test_5_pool_stress.py create mode 100755 deploy/docker/tests/test_6_multi_endpoint.py create mode 100755 deploy/docker/tests/test_7_cleanup.py diff --git a/deploy/docker/STRESS_TEST_PIPELINE.md b/deploy/docker/STRESS_TEST_PIPELINE.md new file mode 100644 index 00000000..44025514 --- /dev/null +++ b/deploy/docker/STRESS_TEST_PIPELINE.md @@ -0,0 +1,241 @@ +# Crawl4AI Docker Memory & Pool Optimization - Implementation Log + +## Critical Issues Identified + +### Memory Management +- **Host vs Container**: `psutil.virtual_memory()` reported host memory, not container limits +- **Browser Pooling**: No pool reuse - every endpoint created new browsers +- **Warmup Waste**: Permanent browser sat idle with mismatched config signature +- **Idle Cleanup**: 30min TTL too long, janitor ran every 60s +- **Endpoint Inconsistency**: 75% of endpoints bypassed pool (`/md`, `/html`, `/screenshot`, `/pdf`, `/execute_js`, `/llm`) + +### Pool Design Flaws +- **Config Mismatch**: Permanent browser used `config.yml` args, endpoints used empty `BrowserConfig()` +- **Logging Level**: Pool hit markers at DEBUG, invisible with INFO logging + +## Implementation Changes + +### 1.

POST /monitor/stats/reset - Reset counters - Redis persistence for endpoint stats (survives restart) - Timeline tracking (5min window, 5s resolution, 60 data points) **Frontend Dashboard** (`/dashboard`): - **System Health Bar**: CPU%, Memory%, Network I/O, Uptime - **Pool Status**: Live counts (permanent/hot/cold browsers + memory) - **Live Activity Tabs**: - Requests: Active (realtime) + recent completed (last 100) - Browsers: Detailed table with actions (kill/restart) - Janitor: Cleanup event log with timestamps - Errors: Recent errors with stack traces - **Endpoint Analytics**: Count, avg latency, success%, pool hit% - **Resource Timeline**: SVG charts (memory/requests/browsers) with terminal aesthetics - **Control Actions**: Force cleanup, restart permanent, reset stats - **Auto-refresh**: 5s polling (toggleable) **Integration:** - Janitor events tracked (close_cold, close_hot, promote) - Crawler pool promotion events logged - Timeline updater background task (5s interval) - Lifespan hooks for monitor initialization **UI Design:** - Terminal vibe matching Crawl4AI theme - Dark background, cyan/pink accents, monospace font - Neon glow effects on charts - Responsive layout, hover interactions - Cross-navigation: Playground ↔ Monitor **Key Features:** - Zero-config: Works out of the box with existing Redis - Real-time visibility into pool efficiency - Manual browser management (kill/restart) - Historical data persistence - DevOps-friendly UX Routes: - API: `/monitor/*` (backend endpoints) - UI: `/dashboard` (static HTML) ---

Add lock protection for browser pool access in monitor stats - Ensure async track_janitor_event across all call sites - Improve error handling in monitor request tracking (already in place) Important Fixes: - Replace fire-and-forget Redis with background persistence worker - Add time-based expiry for completed requests/errors (5min cleanup) - Implement input validation for monitor route parameters - Add 4s timeout to timeline updater to prevent hangs - Add warning when killing browsers with active requests - Implement monitor cleanup on shutdown with final persistence - Document memory estimates with TODO for actual tracking Frontend Enhancements: WebSocket Real-time Updates: - Add WebSocket endpoint at /monitor/ws for live monitoring - Implement auto-reconnect with exponential backoff (max 5 attempts) - Add graceful fallback to HTTP polling on WebSocket failure - Send comprehensive updates every 2 seconds (health, requests, browsers, timeline, events) UI/UX Improvements: - Add live connection status indicator with pulsing animation - Green "Live" = WebSocket connected - Yellow "Connecting..." = Attempting connection - Blue "Polling" = Fallback to HTTP polling - Red "Disconnected" = Connection failed - Restore original beautiful styling for all sections - Improve request table layout with flex-grow for URL column - Add browser type text labels alongside emojis - Add flex layout to browser section header Testing: - Add test-websocket.py for WebSocket validation - All 7 integration tests passing successfully Summary: 563 additions across 6 files --- deploy/docker/crawler_pool.py | 6 +- deploy/docker/monitor.py | 179 ++++++++++---- deploy/docker/monitor_routes.py | 95 +++++++- deploy/docker/server.py | 13 +- deploy/docker/static/monitor/index.html | 305 +++++++++++++++++++++++- deploy/docker/test-websocket.py | 34 +++ 6 files changed, 561 insertions(+), 71 deletions(-) create mode 100755 deploy/docker/test-websocket.py diff --git a/deploy/docker/crawler_pool.py b/deploy/docker/crawler_pool.py index 95593b3f..509cbba9 100644 --- a/deploy/docker/crawler_pool.py +++ b/deploy/docker/crawler_pool.py @@ -61,7 +61,7 @@ async def get_crawler(cfg: BrowserConfig) -> AsyncWebCrawler: # Track promotion in monitor try: from monitor import get_monitor -

Changes: - Renamed docker-deployment.md → self-hosting.md to better reflect the value proposition - Updated mkdocs.yml navigation to "Self-Hosting Guide" - Completely rewrote introduction emphasizing self-hosting benefits: * Data privacy and ownership * Cost control and transparency * Performance and security advantages * Full customization capabilities - Expanded "Metrics & Monitoring" → "Real-time Monitoring & Operations" with: * Monitoring Dashboard section documenting the /monitor UI * Complete feature breakdown (system health, requests, browsers, janitor, errors) * Monitor API Endpoints with all REST endpoints and examples * WebSocket Streaming integration guide with Python examples * Control Actions for manual browser management * Production Integration patterns (Prometheus, custom dashboards, alerting) * Key production metrics to track - Enhanced summary section: * What users learned checklist * Why self-hosting matters * Clear next steps * Key resources with monitoring dashboard URL The monitoring dashboard built 2-3 weeks ago is now fully documented and discoverable. Users will understand they have complete operational visibility at http://localhost:11235/monitor with real-time updates, browser pool management, and programmatic control via REST/WebSocket APIs.
