How to reboot a WSGI application
Question:
There are a lot of implementation for the WSGI specification, like mod_wsgi and Phusion Passenger. Now I have bought a shared Python host which uses Phusion Passenger. AFAIK there is no standard for how to reboot a WSGI application, so each implementation has its own way. For example in Phusion Passenger just touching the restart.txt file does the trick. My question is: Is there any way to reboot a WSGI application regardless of what implementation is used using Python?
Answers:
No, there is no standardized way to reboot a WSGI application that works across all implementations. As you mentioned, each implementation has its own way of restarting the application.
In general, the way to restart a WSGI application is to cause the underlying WSGI server to reload the application. The exact mechanism for doing this will depend on the specific WSGI server being used.
If you’re using a shared Python host that uses Phusion Passenger, then the recommended way to restart the application is to touch the restart.txt file, as you mentioned. This file is used by Phusion Passenger to signal that the application should be restarted.
If you’re using a different WSGI server, you’ll need to consult the documentation for that server to determine the appropriate way to restart the application. For example, if you’re using mod_wsgi, you might need to restart the Apache server in order to reload the application.
In general, it’s best to consult the documentation for your specific WSGI server to determine the appropriate way to restart the application.
