Fixing Python Script with Eventlet and Redis TLS

Issue:

The current script using Eventlet and Redis with TLS is facing connection issues, and it seems that Eventlet monkey patching might be affecting the connection to Redis.

requirements.txt

  • I chose the versions below because they are compatible with each other
Flask==2.3.0
eventlet==0.32.0
redis==3.5.3
numpy==1.21.0

Solution Steps:

  1. Update Libraries:

    • Make sure you are using the latest versions of eventlet, Flask, and redis. Update them using:

      pip install -U eventlet Flask redis
  2. Order of Import and Monkey Patching:

    • Move the eventlet.monkey_patch() line to after the imports but before any other code that relies on those imports. Adjust the script as follows:

      import datetime
      from urllib.parse import urlparse
      from subprocess import Popen
      import eventlet
      from flask import Flask
      
      eventlet.monkey_patch()
      
      import redis
      import numpy as np
      
      # Rest of the script remains unchanged
  3. Separate Flask into a Subprocess:

    • Use the subprocess module to start the Flask application in a separate process. This can help avoid interference between Eventlet monkey-patching and Redis TLS connections.

      if __name__ == "__main__":
          flask_process = Popen(["python", __file__])
          try:
              my_application.run(debug=True)
          finally:
              flask_process.terminate()
  4. Testing:

    • Before running the script, ensure that you have a Redis server with TLS support running, and replace the REDIS_URL placeholder with the correct connection information.
  5. Run the Script:

    • Save the script and run it
