From 20db68a97f3ddd7b29bb4a9e3d2e4187c9b53c3c Mon Sep 17 00:00:00 2001 From: Joe Particle Date: Wed, 16 Jul 2025 16:20:52 +0000 Subject: [PATCH] feat: Implement comprehensive logging enhancement system - Add advanced log rotation strategies (size, time, hybrid) - Implement automatic log compression for 70-90% space savings - Add correlation IDs for tracking related log entries - Include performance monitoring with uptime and request counting - Add hostname and version metadata to all log entries - Implement log validation and statistics functionality - Add automatic cleanup of old log files - Enhance systemd journal integration - Provide comprehensive configuration options - Maintain full backward compatibility - Add extensive documentation and test suite This completes the logging enhancement with production-ready features for structured logging, rotation, and monitoring. --- TODO.md | 8 +- src/apt-ostree.py/CHANGELOG.md | 31 ++ src/apt-ostree.py/LOGGING_ENHANCEMENT.md | 351 ++++++++++++++++++++++ src/apt-ostree.py/python/utils/config.py | 24 +- src/apt-ostree.py/python/utils/logging.py | 287 ++++++++++++++++-- test_enhanced_logging.py | 213 +++++++++++++ 6 files changed, 892 insertions(+), 22 deletions(-) create mode 100644 src/apt-ostree.py/LOGGING_ENHANCEMENT.md create mode 100644 test_enhanced_logging.py diff --git a/TODO.md b/TODO.md index 8afa686..7fbed02 100644 --- a/TODO.md +++ b/TODO.md @@ -149,7 +149,13 @@ -
