Is raven thread and process safe?

When I test it with multi process, my server does not receive any message. I try to find the reason. It seems that the message go to the Queue, but cannot be picked out. In fact, although I config handler for each process, they use the same handler and the same transport object. The worker object block at Queue.get method.

I config the handler like this in each process.

logger = logging.getLogger()
logger.handlers = []
client = Client(os.getenv('SENTRY_DSN'))
handler = SentryHandler(client)
handler.setLevel(logging.ERROR)
logger.addHandler(handler)

The worker object block at this statement. File: raven/transport/threaded.py Line 133, record = self._queue.get()

    def _target(self):
        while True:
            record = self._queue.get()  # This statement blocks.
            try:
                if record is self._terminator:
                    break
                callback, args, kwargs = record
                try:
                    callback(*args, **kwargs)
                except Exception:
                    logger.error('Failed processing job', exc_info=True)
            finally:
                self._queue.task_done()

            sleep(0)

Only the main process send the message successful. Btw, because, my raven version is 5.2.0.

Sorry… I forgot there is a link… I thought they will work with it… In my code, I just write a init log function. This function will be called first in the new process.

def init_log(sentry_dsn, sentry_level=logging.ERROR):
    import raven
    from raven.handlers.logging import SentryHandler
    from raven.transport.registry import TransportRegistry, default_transports
    raven.Raven = None
    raven.Client.logger = logging.getLogger('raven')
    raven.Client._registry = TransportRegistry(transports=default_transports)
    client = raven.Client(sentry_dsn)
    handler = SentryHandler(client)
    handler.setLevel(sentry_level)
    logger.addHandler(handler)

Or you can simply don’t use log before fork process.
