[medusa] asyncore.py descriptor-map hack (original) (raw)

I changed asyncore.dispatcher to cache fileno() information in a dictionary stored at the class level. This dictionary can be used to feed select() file descriptors directly, therefore removing its need to call the fileno() method of each socket object. [this was doubly bad because it would trigger a getattr call].

It's possible that this will remove a significant amount of overhead from poll(), but I don't have time to thoroughly test it for speed right now.

For those who might be interested, it's checked in as revision 2.41. [2.40 and 2.42 are exactly the same, I couldn't figure out how to correctly make a branch with CVS within 10 minutes so I gave up]

The following command will do the trick: $ cvs up -r2.41 asyncore.py
