ProxyBroker2 v2.0.0b1 - Production Ready Beta 🚀

🎉 Major Milestone: ProxyBroker2 is Production-Ready!

This beta release represents a complete modernization and stabilization of ProxyBroker, making it ready for production use with zero critical bugs and comprehensive test coverage.

✨ Key Highlights

🔧 Critical Bug Fixes

• ✅ Fixed ProxyPool heap corruption - Proper min-heap maintenance with avg_resp_time priority
• ✅ Added timeout/retry limits - Prevents infinite loops in proxy import operations
• ✅ Deterministic protocol selection - Clear priority order (SOCKS5 → SOCKS4 → CONNECT → HTTPS → HTTP)
• ✅ Signal handler cleanup - Proper memory management prevents leaks
• ✅ Modern SSL handling - Uses asyncio.start_tls() instead of deprecated patterns
• ✅ Exception chaining - Proper error propagation with raise ... from err

🚀 Production-Ready Status

• Zero critical bugs - All signal handler leaks, deadlocks, and heap corruption fixed
• 100% test suite pass rate - All 131 tests passing with comprehensive coverage
• Python 3.10-3.13 support - Full compatibility with latest Python versions
• Modern async patterns - Updated from deprecated asyncio patterns

🛠️ API Improvements

• Proxy.types setter - Direct assignment and update operations with type validation
• Cache invalidation - Schemes properly refresh when types change
• Async context managers - Server lifecycle management
• Resource cleanup - Comprehensive connection and SSL cleanup

🧪 Modern Testing Philosophy

• Behavior-focused tests - Contract-based testing protects APIs during refactoring
• 131 passing tests - Comprehensive coverage across all components
• Mock infrastructure - Realistic testing without external dependencies
• Integration tests - End-to-end workflow validation

🔄 Updated Dependencies (May 2025)

• aiohttp 3.10.11 → 3.12.0 (asyncio deprecation fixes)
• aiodns 3.1.1 → 3.4.0 (DNS resolution improvements)
• attrs 22.1.0 → 25.3.0 (Python 3.10+ optimizations)
• pytest 7.1.2 → 8.3.5 (modern testing framework)

📚 Enhanced Documentation

• Updated architecture guide with clear component explanations
• Modern toolchain documentation (ruff, pytest, poetry)
• Migration guide for smooth transition from v1.x
• Auto-generated API reference from high-quality docstrings

🎯 Perfect for Production Use

Web Scraping & Automation

import asyncio
from proxybroker import Broker

async def main():
    proxies = asyncio.Queue()
    broker = Broker(proxies)
    await broker.find(types=['HTTP', 'HTTPS'], limit=10)

asyncio.run(main())

Proxy Server Deployment

import asyncio
from proxybroker import Broker

async def main():
    proxies = asyncio.Queue()  
    broker = Broker(proxies)
    await broker.serve(host='127.0.0.1', port=8888, types=['HTTP', 'HTTPS'])

asyncio.run(main())

🔄 Migration from v1.x

ProxyBroker2 maintains API compatibility while adding modern features:

• All existing code continues to work
• New type validation provides better error messages
• Enhanced async patterns improve performance
• Modern Python 3.10+ support
