From 6f0499e48a71391a0a9ac74d4564ce27a23fca32 Mon Sep 17 00:00:00 2001 From: Bearice Ren Date: Wed, 27 Aug 2025 02:19:35 +0900 Subject: [PATCH 1/3] feat: implement Phase 1 unified HTTP architecture foundation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add generic connection pool with trait-based design for protocol-agnostic pooling - Create protocols/http module with HTTP stream abstractions and protocol handler traits - Implement UDP channel lifecycle management with proper session ID generation - Add ALPN-based protocol selection for HTTP/1.1, HTTP/2, and HTTP/3 negotiation - Reorganize code structure: move HTTP-specific code from common/ to protocols/ - Add type aliases to reduce trait object complexity - Fix safety issues: input validation, underflow protection, anyhow error integration - Optimize connection pool with read-then-write lock pattern for better concurrency This establishes the foundation for unified HTTP listener/connector supporting all HTTP versions with proper connection pooling and protocol negotiation. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude refactor: modernize TLS infrastructure and migrate to aws-lc-rs - Migrate from ring to aws-lc-rs crypto provider for better performance - Remove unsupported TLS configuration options (session_tickets, early_data, etc.) - Implement SNI certificate loading with ResolvesServerCertUsingSni - Remove empty configuration structs (TlsCryptoConfig, TlsAlpnConfig) - Consolidate TLS handshake methods: tls_handshake_server() returns (stream, alpn_protocol) tuple - Update socket operations to extract ALPN protocol from TLS streams - Update listeners to handle new TLS handshake signature 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude refactor: rename HTTP types for clarity and prepare for unified architecture - Rename HttpRequest/HttpResponse to HttpRequestV1/HttpResponseV1 for clarity - Update all HTTP proxy code to use new type names throughout codebase - Update context to use set_http_request_v1() method - Prepare foundation for unified HTTP protocol architecture - Maintain backward compatibility for existing HTTP/1.1 functionality This change disambiguates the existing HTTP/1.1 specific types from the upcoming unified HTTP protocol types that will support HTTP/1.1, HTTP/2, and HTTP/3. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude feat: implement HTTP/1.1 protocol handler with unified httpx listener This commit implements Phase 2 of the unified HTTP architecture: - **HTTP/1.1 Protocol Handler**: Complete implementation with request/response parsing, CONNECT tunneling, and WebSocket upgrade support - **Unified httpx Listener**: Multi-protocol listener with ALPN negotiation supporting HTTP/1.1, HTTP/2, HTTP/3 (foundation) - **Stream Architecture**: Refactored socket operations to use IOStream trait for better abstraction - **Comprehensive Testing**: Full test suite including performance, security, and integration tests - **Loop Detection**: Configurable loop detection with hop limits for proxy chains Key Features: - HTTP CONNECT method tunneling for HTTPS traffic - WebSocket protocol upgrade handling - Request/response streaming with proper Content-Length and chunked encoding - TLS termination with ALPN protocol negotiation - Authentication integration with existing auth framework - Comprehensive error handling and logging All tests pass including httpx listener tests, HTTP/1.1 protocol tests, and integration tests. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude refactor: implement unified I/O architecture and HTTP/1.1 improvements - Refactor Context API to use Option instead of Result for cleaner error handling - Add comprehensive I/O module with bidirectional copying, buffered streams, and splice optimization - Implement unified HTTP/1.1 protocol handler consolidating parser and stream functionality - Improve copy_bidi with modular design supporting both stream and frame-based protocols - Add configurable I/O loop functions to Context for protocol-specific handling - Enhanced ContextStatistics with sent_bytes/sent_frames tracking methods 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude refactor: migrate comprehensive testing to pytest infrastructure - Replace custom test framework with pytest-native approach using fixtures and conftest.py - Restructure test files into organized test suites: httpx/, matrix/, performance/, security/ - Add pytest plugins for HTML reporting, JSON output, and parameterized test execution - Improve Docker configuration for better debugging (debug builds, additional tools) - Migrate from individual Python test scripts to structured pytest test modules - Remove deprecated test framework files and consolidate shared utilities This modernizes the testing infrastructure while maintaining all existing test coverage and improves maintainability through standard pytest patterns. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude refactor: remove empty Http1Handler struct and move protocol functions to handler - Convert Http1Handler from empty struct to standalone functions, eliminating unnecessary allocations - Move HTTP protocol utility functions from io.rs to handler.rs for better separation of concerns: - expects_100_continue() - should_keep_alive() - prepare_client_response() - prepare_server_request() - Update all call sites to use standalone functions instead of struct methods - Move corresponding tests from io_test.rs to handler.rs test module - Update module exports and imports throughout codebase 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude refactor: remove unused HTTP/2 and HTTP/3 handler stubs - Remove unimplemented Http2Handler and Http3Handler placeholder structs - Clean up exports from http/mod.rs that referenced removed handlers - Clear HTTP/2 and HTTP/3 mod.rs files as they contained only stub implementations These handlers were empty implementations with only bail!() macros and were never actually used in the codebase. They can be re-added when actual HTTP/2 and HTTP/3 support is implemented. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude style: fix code formatting and whitespace in I/O modules - Remove extra blank lines in bidirectional.rs splice loop - Fix comment spacing in copy.rs test mock - Add proper spacing in http_forward_tests.rs loop formatting - Minor whitespace cleanup for consistency 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude refactor: improve HTTP/1.1 error handling and code organization Major improvements to HTTP/1.1 implementation following code review: **Error Handling Improvements:** - Fix accept() error handling in httpx listener - move retry logic to SocketOps layer - Add proper error responses to clients when server response reading fails (HTTP 502) - Fix stream ownership bug in http_io_loop error handling - Classify accept() errors properly: transient vs fatal **Code Organization:** - Extract handle_100_continue_cycle() function to eliminate 4-level nesting - Use consistent StreamPair type throughout HTTP/1.1 implementation - Clean up imports following project conventions (all imports at file header) - Add #[allow(unused_assignments)] to suppress false positive warnings **Architecture:** - Move socket-level retry logic from application layer to SocketOps layer - Simplify listener implementations - only handle truly fatal errors - Improve separation of concerns between socket ops and HTTP protocol logic **Reliability:** - Ensure clients always receive proper HTTP error responses instead of dropped connections - Handle 100 Continue protocol flow more robustly with better error recovery - Make accept() loops resilient to transient network errors 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- CLAUDE.md | 4 +- src/common/connection_pool.rs | 409 ++++++++ src/common/http.rs | 19 +- src/common/http_proxy.rs | 107 +- src/common/mod.rs | 1 + src/common/rfc9298_tests.rs | 20 +- src/common/socket_ops.rs | 121 ++- src/connectors/direct.rs | 11 +- src/connectors/http.rs | 8 +- src/context.rs | 28 +- src/lib.rs | 4 + src/listeners/http.rs | 20 +- src/listeners/http_forward_tests.rs | 8 +- src/listeners/httpx.rs | 1136 +++++++++++++++++++++ src/listeners/mod.rs | 2 + src/listeners/reverse.rs | 4 +- src/listeners/socks.rs | 8 +- src/protocols/http/http1/callback.rs | 380 +++++++ src/protocols/http/http1/handler.rs | 941 +++++++++++++++++ src/protocols/http/http1/io.rs | 523 ++++++++++ src/protocols/http/http1/io_test.rs | 1280 ++++++++++++++++++++++++ src/protocols/http/http1/mod.rs | 14 + src/protocols/http/http2/mod.rs | 0 src/protocols/http/http3/mod.rs | 0 src/protocols/http/mod.rs | 212 ++++ src/protocols/mod.rs | 1 + tests/comprehensive/Dockerfile | 8 +- tests/comprehensive/Makefile | 3 +- tests/comprehensive/README.md | 4 +- tests/comprehensive/config/httpx.yaml | 46 + tests/comprehensive/docker-compose.yml | 2 +- tests/rfc9298_comprehensive_tests.rs | 8 +- tests/rfc9298_integration_tests.rs | 6 +- 33 files changed, 5167 insertions(+), 171 deletions(-) create mode 100644 src/common/connection_pool.rs create mode 100644 src/listeners/httpx.rs create mode 100644 src/protocols/http/http1/callback.rs create mode 100644 src/protocols/http/http1/handler.rs create mode 100644 src/protocols/http/http1/io.rs create mode 100644 src/protocols/http/http1/io_test.rs create mode 100644 src/protocols/http/http1/mod.rs create mode 100644 src/protocols/http/http2/mod.rs create mode 100644 src/protocols/http/http3/mod.rs create mode 100644 src/protocols/http/mod.rs create mode 100644 src/protocols/mod.rs create mode 100644 tests/comprehensive/config/httpx.yaml diff --git a/CLAUDE.md b/CLAUDE.md index 335ccff0..6f9c5b85 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -74,4 +74,6 @@ All configuration is YAML-based with these main sections: - `timeouts` - Connection timeout settings - `ioParams` - Buffer sizes and splice configuration -The comprehensive CONFIG_GUIDE.md and MILU_LANG_GUIDE.md provide detailed configuration reference. \ No newline at end of file +The comprehensive CONFIG_GUIDE.md and MILU_LANG_GUIDE.md provide detailed configuration reference. +- always import what you use, do not use abs path like crate::protocols::http::HttpVersion::Http1, always put import at head of file. +- you should always puut test at end of file \ No newline at end of file diff --git a/src/common/connection_pool.rs b/src/common/connection_pool.rs new file mode 100644 index 00000000..1fac6a81 --- /dev/null +++ b/src/common/connection_pool.rs @@ -0,0 +1,409 @@ +use crate::context::ContextRef;

2025 16:09:35 +0900 Subject: [PATCH 2/3] feat: implement unified HTTP/1.1 httpx connector with WebSocket upgrade support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit introduces a modern httpx connector that unifies HTTP proxy functionality with configurable WebSocket upgrade handling and comprehensive protocol support. ## Key Features ### HttpX Connector Implementation - Modern HTTP/1.1 proxy connector with connection pooling - Configurable forward proxy mode (GET/POST/PUT/DELETE support) - Advanced timeout controls (connect, resolve) - Protocol negotiation and keep-alive management ### WebSocket Upgrade Handling - NEW: `intercept_websocket_upgrades` configuration flag - Automatically routes WebSocket upgrades through CONNECT tunneling - Prevents HTTP proxies from stripping hop-by-hop headers - Configurable behavior for compatibility with different upstream proxies ### Test Suite Reorganization - Restructured httpx tests into 3-tier architecture for component isolation: * Tier 1: HttpX Listener + Direct Connector (listener validation) * Tier 2: HttpX Listener + HttpX Connector (full pipeline testing) * Tier 3: Reverse Listener + HttpX Connector (connector validation) - Consolidated 12 separate test files into 3 organized test classes - All 49 tests passing with comprehensive coverage ### Documentation Updates - Complete CONFIG_GUIDE.md documentation for httpx listener (Section 4.7) - Complete CONFIG_GUIDE.md documentation for httpx connector (Section 5.7) - Multi-protocol support documentation (HTTP/1.1, HTTP/2, HTTP/3) - ALPN negotiation and configuration requirements - WebSocket upgrade configuration examples ## Technical Implementation ### Connection Architecture - Unified I/O architecture with bidirectional copying - Connection pooling with configurable idle timeout - Protocol-specific configuration embedding - Advanced error handling and resource cleanup ### HTTP Context Integration - Enhanced HTTP context for request/response tracking - WebSocket upgrade detection using existing helper methods - CONNECT tunneling decision logic - Memory-efficient request processing ### Configuration Schema ```yaml connectors: - name: httpx type: httpx server: "http-proxy" port: 3128 enable_forward_proxy: true intercept_websocket_upgrades: true # NEW protocol: type: "http/1.1" keep_alive: true pool: enable: true max_connections: 50 idle_timeout_secs: 30 ``` ## Files Modified - src/connectors/httpx.rs (NEW) - Main httpx connector implementation - src/protocols/http/http_context.rs (NEW) - HTTP context integration - CONFIG_GUIDE.md - Comprehensive httpx documentation - tests/comprehensive/config/httpx.yaml - 3-tier test configuration -
