Handle logging before we are ready to write it out to disk.
32
This module defines the PreLogger class, which simply remembers logging
33
records instead of outputing them somewhere. In plat.util.setup_logging(), we
34
retrieve records and write them out to disk after logging is setup.

class PreLogger(logging.Handler):
41
logging.Handler.__init__(self)
44
def emit(self, record):
45
self.records.append(record)

if _handler is not None:
54
raise ValueError("Prelogger already installed")
55
_handler = PreLogger()

logger.addHandler(_handler)
