This enhancement will expose all loggers contained in the logging package. The motivation was to expose RotatingFileHandler and TimedRotatingFileHandler.
I'm not convinced that the implicit tupple structure of args is ideal, it seems prone to errors. On the other hand, I've got no better suggestion at the moment.
import logging
import logging.handlers
def _get_handlers(handlers, formatters):
for key, handler in handlers.items():
kw = {}
try:
cls = handler.get("class")
args = handler.get("args", tuple())
level = handler.get("level", None)
try:
cls = getattr(sys.modules['logging'],cls)
except AttributeError:
try:
cls = getattr(sys.modules['logging.handlers'],cls)
except AttributeError,err:
raise ConfigError("Specified class in handler %s is not a recognizable logger name" % key)
try:
handler_obj = cls(*eval(args))
except IOError,err:
raise ConfigError("Missing or wrong argument to %s in handler %s -> %s "%(cls.__name__,key,err))
except TypeError,err:
raise ConfigError("Wrong format for arguments to %s in handler %s -> %s"%(cls.__name__,key,err))
if level:
level = eval(level, logging.__dict__)
handler_obj.setLevel(level)
except KeyError:
raise ConfigError("No class specified for logging handler %s" % key)
formatter = handler.get("formatter", None)
if formatter:
try:
formatter = formatters[formatter]
except KeyError:
raise ConfigError("Handler %s references unknown "
"formatter %s" % (key, formatter))
handler_obj.setFormatter(formatter)
handlers[key] = handler_obj
