Delay on restart

I have a Flask app where is my main.py

from king_slayer.database import init_db, manager
from king_slayer.views import fetch_production
if __name__ == '__main__':
    init_db()
    manager.run()

      

        
        
        
      

    

Before doing, manger.run()

I want to call

fetch_production() 

      

        
        
        
      

    

so i did it.

from king_slayer.database import init_db, manager
from king_slayer.views import fetch_production

if __name__ == '__main__':
    init_db()
    with manager.app.test_request_context():
        fetch_production()
    manager.run()

      

        
        
        
      

    

It works.
The problem is that I kill the application Flask

and then restart it, it doesn't start in 60-120 seconds. No mistakes, nothing. The browser won't load anything. a simple Loading Problem page appears and after that it works fine unless I restart the app again Flask

.

If I delete

with manager.app.test_request_context():
            fetch_production()

      

        
        
        
      

    

there is no delay.

PS If I don't use with manager.app.test_request_context():

Flask it throws this error.

Traceback (most recent call last):

What's happening?

PPS fetch_production()

does something like this

requests.get(config.SERVER, auth=HTTPBasicAuth(config.AUTH_USER, config.AUTH_PASSWORD))

      

        
        
        
      

    

performs several functions, functions defined in views.py

, and then creates a file .ini

in the file system. Then a is returned at the end return jsonify

.

  requests.get(config.SERVER, auth=HTTPBasicAuth(config.AUTH_USER, config.AUTH_PASSWORD))

      

        
        
        
      

    

is actually very fast, and if fetch_production()

called manually, it takes no more than a few milliseconds.
