I have an app I'm working on, and until this point it's been done utilizing a .tac file. Recent changes in requirements are encouraging a change to use the Twisted plugin system instead. This seems clear for the most part, but I'm unsure about the logging.
Specifically, in the .tac version, I'm using this:
lf = logfile.DailyLogFile("my.log", ".") logname = "testlog" configure_python_logging(lf, logname) application.setComponent(log.ILogObserver, log.PythonLoggingObserver(logname).emit)
However, in the plugin version, I'm not sure how to proceed since I don't have an application object. I can't seem to find any documentation for configuring logging with plugins, either. Is there a way to make this work?
This is a limitation of the implementation of twistd's plugin support. tac files can define custom log observers. Plugins for twistd cannot. Ticket #638 was originally for all of the custom logging feature, but it was eventually split up and the tac parts moved to a separate ticket, #3534, which is now resolved. #638 is still open, however. #3538 is another related ticket which proposes an alternate solution to the problem, allowing tacs and plugins to be used in combination.
