Async I/O for Python 3

Re:Async I/O for Python 3 by ekimekim on Monday March 18, 2013 @06:01PM (#5397458)

A minor gripe (seperate from all my other gripes, which other people have already talked about):

"...run code in another thread - sometimes there is no alternative - eg. getaddrinfo(), database connections"

Just thought I'd mention that async-supporting DNS libs do exist (eg. gevent ships with C-ares), and in particular I've used async postgres database connections in both C and gevent. The code to gevent-ise psycopg2 connections is about 10 or 15 lines, iirc.

Because psycopg2 has supported async OOTB since 2.2 by exposing a pollable socket: http://initd.org/psycopg/docs/advanced.html#asynchronous-sup...

There are limitations though, as noted by the docs: COPY and LOs don't work.
