Feb 1, 2025February 2025 monthly summary for CollaboraOnline/online focusing on reliability, performance, and test stability. Delivered three major initiatives: - Watchdog Reliability Enhancements for Process Termination: robust termination of hung processes with aggressive SIGKILL after 30 seconds if SIGABRT fails, plus thorough handling of termination failures and lifecycle monitoring of background save processes. - Tile Rendering Performance Diagnostics and Rate Limiting: rate-limiting for tile combine requests to allow server time for keyframe responses, plus enhanced diagnostics for large render areas to facilitate debugging and performance analysis. - Testing Infrastructure Stabilization and Test Environment Hardening: refactors to align performance tests with current configuration, updates to test load scripts for renamed variables, guards against environment-specific APIs (CSSStyleSheet.replace), inline CSS variables for JSDOM compatibility, and adjustments to test environment variable handling to prevent failures. This work improves reliability, reduces hang-related risks, stabilizes performance testing, and enhances observability for performance issues, enabling faster, safer releases.
