Oct 1, 2025October 2025: Higress rate-limiting enhancement focused on accuracy, robustness, and predictable quotas. Implemented fixed-window rate limiting across cluster, AI token, and WASM plugin paths by refactoring the core logic and updating Redis key formats and Lua scripts to track current counts precisely, including edge cases and initialization states. The changes reduce miscounts during bursts and startup, improving reliability and security of API quotas across critical paths.

Jul 1, 2025July 2025 summary: Delivered global rate limiting for AI token rate limiter in Higress, adding a single threshold for an entire rule group to complement existing per-key rate limiting. Implemented updates to configuration parsing, Redis key generation, and core rate-limiting logic to support group-level thresholds across routes. No major bugs fixed this month. The work reduces operational risk, simplifies policy management, and improves throughput control for AI token traffic.

Feb 1, 2025February 2025 monthly summary for alibaba/higress. Focused on strengthening testing coverage and policy enforcement. Key features delivered include an end-to-end testing framework for the ai-proxy WASM plugin driven by an LLM mock server, with new test cases for Baidu, Doubao, Minimax, and Qwen, covering both streaming and non-streaming requests; README and LLM mock server configuration were updated to improve usability. Major bugs fixed include ext-auth plugin enhancements with robust parsing tests for configuration rules and the introduction of HTTP method matching in blacklist/whitelist modes, improving policy enforcement and reliability. Overall impact: increased confidence in production deployments, faster iteration cycles, broader AI-provider validation, and stronger access control. Technologies/skills demonstrated: Go-based plugin development, end-to-end/integration testing, LLM mock server integration, robust configuration parsing, HTTP method policy enforcement, and comprehensive documentation.

Jan 1, 2025Concise monthly summary for 2025-01 focusing on Higress work: Implemented critical authentication enhancements and reliability fixes to improve security stance, resiliency, and developer productivity. Delivered ext-auth plugin with blacklist/whitelist support, refactored configuration parsing, and added utilities to handle complex authentication scenarios—enabling more flexible access control and easier onboarding of new policies. Key achievements: - Ext-auth Plugin: Blacklist/Whitelist Support (refactored config parsing; added utilities) with commit 0259eaddbbb14b0a25359fd74d051bb954bd728d. - ai-proxy Minimax Pro API Response Handling: fixed blocking responses and aligned data mapping and error handling with Pro API structure (commit a1bf315b13e40f3351e9efe567c37de37efad3fc). - External Authentication Crash: Request Path Handling: corrected request path retrieval/processing, ensured buffering where needed, and resume of HTTP requests after ext-auth to prevent deadlocks (commit 9d8e78dae303cf0b4f80aaf823d802e59d0bd081). - Envoy Authentication Path Join Bug: fixed path concatenation by using path.Join instead of url.JoinPath for robust routing in Envoy endpoint mode (commit 574d1aa36a01e8d70c7d118510742c800967decf). Overall impact and accomplishments: - Strengthened authentication reliability and flexibility, reducing deadlocks and misrouted requests in production flows. - Improved integration with external AI services and updated API contracts to minimize runtime errors. - Clearer, more maintainable configuration handling enabling faster policy changes and onboarding. Technologies/skills demonstrated: - Go/TypeScript coordination for plugin development and API integration. - Robust error handling, data mapping, and API contract alignment. - Refactoring for configuration parsing, routing, and request lifecycle management. - Troubleshooting and rapid fix deployment in a distributed proxy/orchestration environment.

Oct 1, 2024In October 2024, the Higress team delivered Gateway API enablement for alibaba/higress with dynamic Helm-based configuration, enhancing deployment flexibility and gateway reliability. Key changes include enabling PILOT_ENABLE_GATEWAY_API and PILOT_ENABLE_ALPHA_GATEWAY_API, dynamic toggling of gateway API listeners and related environment variables via Helm, and conditional deployment of the gateway controller based on Helm values. We addressed correctness in gateway status updates and ensured gateway names are properly used in service discovery, resulting in more stable gateway behavior and smoother rollout of API features.
