Gunicorn: Can I use pdb with gunicorn to inspect what is happening in my webapp?
Apparently, with cherrypy, you can add pdb.settrace() in the middle of your app code, and then in the terminal where you started cherrypy, after you hit that code in your browser, you can then walk around and inspect stuff.
I just heard about this; I haven't seen it first-hand. But I know that similar stuff exists in .NET and other frameworks.
Could something like this be set up in gunicorn? How?

Easiest method would be to do your pdb configuration in the post_fork hook while using a single sync worker.
If you find something that doesn't actually work, feel free to reopen this.

I stumbled upon this issue and thought I would share the config file I use to do this:
gunicorn_logfile = "/dev/null"
gunicorn_loglevel = "error"
debug = True
timeout = 900000
workers = 1
worker_class = "sync"
Throwing down a pdb.set_trace() then works with either pdbpp or pdb without the debugger getting mixed up with stdout.

That timeout thing was just what I was looking for. Thanks!
