Question

I currently have twisted managing rotating the log files for my application, however the logs are becoming large and I’d like to look at compressing them when they rotate.

I’ve done a quick look through the twisted docs and don’t see how I can do this with the DailyLogFile class.

My setup for logging is:

from twisted.python.log import ILogObserver, FileLogObserver
from twisted.python.logfile import DailyLogFile
...
"Setup the logging"
logPath = os.getcwd() + "/logs/"
logFile = DailyLogFile("lazarus.log", logPath, defaultMode=0644)
application.setComponent(ILogObserver, FileLogObserver(logFile).emit)

Does anyone know how to do this?

You could subclass DailyLogFile and overload the rotate method:

class DailyCompressedLogFile(DailyLogFile):
    def rotate(self):
        super(DailyCompressedLogFile, self).rotate()
        newpath = "%s.%s" % (self.path, self.suffix(self.lastDate))
        if os.path.exists(newpath):
            # compress newpath here
