### crazy hack. the first time Twisted logs something, we will track down
### the logfile it is using, then use that for the Python logging framework
from twisted.python import log
import logging

def capture_log(unused_msg):
    for ob in log.theLogPublisher.observers:
        if hasattr(ob, 'im_class') and ob.im_class is log.FileLogObserver:
            flo = ob.im_self
            logfile = flo.write.im_self
            stream = logfile._file

            ### the follow is similar to svnwcsub.prepare_logging()
            handler = logging.StreamHandler(stream)
            formatter = logging.Formatter(
                            '%(asctime)s [%(levelname)s] %(message)s',
                            '%Y-%m-%d %H:%M:%S')
            handler.setFormatter(formatter)

            # Apply the handler to the root logger
            root = logging.getLogger()
            root.addHandler(handler)

            ### use logging.INFO for now
            root.setLevel(logging.INFO)

            # okay. remove our capture function.
            log.removeObserver(capture_log)

# hook in the capturing...
log.addObserver(capture_log)
