From 070c2a7bd22057d5f84a565f86723fe001f87fcd Mon Sep 17 00:00:00 2001 From: Jacquin Antoine Date: Thu, 26 Feb 2026 23:28:45 +0100 Subject: [PATCH] Refactor: thread-safe per-process state and add tests Major changes: - Move child state from global variable to server config (reqin_log_server_conf_t) - Add reqin_log_create_server_conf() for proper per-server initialization - Fix thread safety for worker/event MPMs - Add cmocka unit tests (test_module_real.c) - Add Python integration tests (test_integration.py) - Update CI workflow and Dockerfiles for test execution - Fix: Remove child_exit hook (not in architecture.yml) Tests: - Unit tests: JSON escaping, ISO8601 formatting, header truncation -
