prologin.web module

Provides utilities for Prologin web applications. Everything should be prologinized like this:

# WSGI application import prologin.web application = prologin.web.WsgiApp(application, ‘app_name’)

# Tornado application import prologin.web application = prologin.web.TornadoApp(handlers, ‘app_name’)

# BaseHTTPServer application class MyRequestHandler(prologin.web.ProloginBaseHTTPRequestHandler):

…

This initializes logging using prologin.log, and maps some special URLs to useful pages:

• /__ping Should always return the string “pong”. Used for health checking.

• /__threads Shows the status of all threads in the process and their current stack.

• [TODO] /__monitoring Exports monitoring values for outside use.
