[GitHub] [pulsar] zbentley opened a new issue #14583: Disposing of a Python Consumer object without calling close() leaks file descriptors and does not close the consumer.

[GitBox <gi...@apache.org>]

zbentley opened a new issue #14583:
URL: https://github.com/apache/pulsar/issues/14583


   **Describe the bug**
   If a Python pulsar-client Consumer object is destroyed (garbage collected) without its `close()` method being called, the consumer remains connected, and its file descriptors remain open.
   
   **To Reproduce**
   Steps to reproduce the behavior:
   1. Run the below snippet.
   2. Observe that it segfaults (due to https://github.com/apache/pulsar/issues/14582). 
   
   ```python
   import logging
   import resource
   import pulsar
   
   def main():
       resource.setrlimit(resource.RLIMIT_NOFILE, (15, 15))
       consumers = []
       for i in range(100):
           client = pulsar.Client(service_url='pulsar://localhost', logger=logging.getLogger())
           print(f"creating mysub-{i}")
           con = client.subscribe(topic='mytopic', subscription_name=f'mysub-{i}')
   
   
   if __name__ == '__main__':
       main()
   
   ```
   
   **Expected behavior**
   Garbage collecting consumers should result in their no longer being present on the system.
   
   **Desktop (please complete the following information):**
    - OS: MacOS Monterey (x86)
    - Pulsar client 2.9.1
