Mar 1, 2026March 2026 monthly summary focused on stabilizing TLS/Plain HTTP interaction in apple/servicetalk. Implemented explicit detection and messaging for TLS ClientHello on non-TLS HTTP ports, improving log diagnostics and reducing operator confusion. Added regression tests to prevent regression. This improves fault isolation, reduces MTTR for misrouted TLS traffic, and strengthens the product's reliability.

Jan 1, 2026January 2026 monthly summary for apple/servicetalk: Implemented total header length limit enforcement with a non-breaking warning by default, accumulating total header lengths and enforcing a configurable limit (default 8k). The behavior aligns with Netty/H2 decoders, and can be upgraded to a strict error via a system property. Added tests covering headers and trailers; groundwork laid for future stricter enforcement without breaking existing users.

Nov 1, 2025November 2025 — Apple/servicetalk monthly summary. Focused on a major build-system modernization to enable faster releases and better maintenance, while aligning with modern Java toolchains. Delivered Gradle Build System Modernization to 9.2.0, including wrapper upgrades and configuration improvements; upgraded the shading tooling and modernized build scripts for compatibility and performance. Fixed build/test reliability by addressing task dependencies for Jersey modules and protobuf generation, and updating SpotBugs configuration for Gradle 9 compatibility. Updated CI/test prerequisites to use Java 17 for Gradle execution and prepared for JDK 25 LTS in the near term. Added/standardized test runtime dependencies (junit-platform-launcher, XmlParser) to improve test reliability. This work reduces build times, increases build stability, and positions the project for faster, safer releases across Java 17+ environments.
