From d224b98893df36b3cd9b5e55672f9476bd07c405 Mon Sep 17 00:00:00 2001 From: Misaka_Company Date: Mon, 1 Jun 2026 13:56:23 +0800 Subject: [PATCH] feat: unified logging module and remove redundant first_run logic - Add logger.py with TimedRotatingFileHandler (daily rotation, 30-day retention) - Replace all print() in migrate.py with logging calls - Add logging to sync.py for sync status tracking - Refactor watch.py to use logger.py, remove duplicate first_run branch - All logs now go to logs/app.log consistently - Add logging config section to config.yaml, add logs/ to .gitignore Co-Authored-By: Claude Opus 4.6 --- .gitignore | 1 + logger.py | 65 ++++++++++++++++++++++++++++++++ migrate.py | 55 ++++++++++++++++----------- sync.py | 8 ++++ watch.py | 108 ++++++++--------------------------------------------- 5 files changed, 124 insertions(+), 113 deletions(-) create mode 100644 logger.py diff --git a/.gitignore b/.gitignore index 692f895..dd386de 100644 --- a/.gitignore +++ b/.gitignore @@ -21,6 +21,7 @@ Desktop.ini .DS_Store # Logs +logs/ *.log watch.log diff --git a/logger.py b/logger.py new file mode 100644 index 0000000..4f124ce --- /dev/null +++ b/logger.py @@ -0,0 +1,65 @@ +""" +Unified logging module. +Provides a pre-configured logger with console + rotating file handlers. +""" + +import logging +import os +from logging.handlers import TimedRotatingFileHandler + + +def setup_logger(name='app', log_dir=None, level='INFO', max_keep_days=30): + """Create and configure a logger. + + Args: + name: Logger name (used as basename for log file). + log_dir: Directory for log files.
