How to debug long running python scripts or services remotely?

Question

Pretty much what the title says, I would like to be able to connect to a python process running under paster or uwsgi and utilize pdb functionality.

Answer 1

Using winpdb, you can attach to a running process like this:

1. Insert

   import rpdb2; rpdb2.start_embedded_debugger('mypassword')
   

   inside your script.

2. Launch your script (through paster or uwsgi) as usual.
3. Run winpdb
4. Click File>Attach
5. Type in password (e.g. "mypassword"), select the process.
6. To detach, click File>Detach. The script will continue to run, and can be attached to again later.
