RabbitMQ-subprocess-client
=====================

RabbitMQ-subprocess-client is a RabbitMq client (based on `pika`) spawning tasks as subprocess, allowing handling segfault gracefully.

# Install
```bash
pip install rabbitmq-subprocess-client
```

# usage
```python
import os
from concurrent.futures import TimeoutError
import traceback
from rabbitmq_subprocess_client import Runner, Consumer

class MyConsumer(Consumer):
def consume_main(self, basic_deliver, msg):
print(f'pre-processing message: {msg} in process: {os.getpid()}')
try:
args = []
kwargs = {}
self.exec(msg, *args, **kwargs) # This will run the consume_subprocess method in a subprocess
self.acknowledge_message(basic_deliver.delivery_tag)
except TimeoutError:
self.nacknowledge_message(basic_deliver.delivery_tag)
except BaseException:
exc_msg = traceback.format_exc()
print(exc_msg)
self.nacknowledge_message(basic_deliver.delivery_tag)

@staticmethod
def consume_subprocess(msg, *args, **kwargs):
print(f'processing message: {msg} in process: {os.getpid()}')
