Monkeypatching the Standard Library ?
The other way of greening an application is simply to monkeypatch the standard library. This has the disadvantage of appearing quite magical, but the advantage of avoiding the late-binding problem.
eventlet.patcher. monkey_patch ( os=None , select=None , socket=None , thread=None , time=None , psycopg=None ) ?This function monkeypatches the key system modules by replacing their key elements with green equivalents. If no arguments are specified, everything is patched:
import eventlet eventlet . monkey_patch ()
The keyword arguments afford some control over which modules are patched, in case that’s important. Most patch the single module of the same name (e.g. time=True means that the time module is patched [time.sleep is patched by eventlet.sleep]). The exceptions to this rule are socket , which also patches the ssl module if present; and thread , which patches thread , threading , and Queue .
Here’s an example of using monkey_patch to patch only a few modules:
import eventlet eventlet . monkey_patch ( socket = True , select = True )
