mixins for tornado
cotimelog, inspired from [ConcurrentLogHandler](https://pypi.python.org/pypi/ConcurrentLogHandler/0.9.1). To be honest, it is almost the same code. Just edit to make the log file rotated by time.
pip install cotimelog
This class is a log handler which is a drop-in replacement for the python standard log handler TimedRotatingFileHandler. The TimedRotatingFileHandler will failed to rotate when multiple processes are trying to write into the same file. You will meet this issue when you use uwsgi. This ConcurrentTimeRotatingFileHandler class is mainly developed to fix this issue.
import os import time from logging import getLogger, INFO from cotimelog import ConcurrentTimeRotatingFileHandler # Use an absolute path to prevent file rotation trouble. log = getLogger() logfile = os.path.abspath("mylogfile.log") # Rotate log after 1 second rotateHandler = ConcurrentTimeRotatingFileHandler(logfile, mode="a", when="S", backupCount=5) log.addHandler(rotateHandler) log.setLevel(INFO) [log.info(str(i)) for i in range(10)] time.sleep(1) [log.info(str(i)) for i in range(10, 100)]
