[New-bugs-announce] [issue2944] asyncore doesn't handle connection refused correctly

[Alexander Shigin]

New submission from Alexander Shigin <shigin at rambler-co.ru>:

Unix select returns socket in read fd set and write fd set if 
nonblocking socket attempts to connect to unaviable address. 

asyncore should check this case by calling getsockopt with SO_ERROR 
optname. If return value is 0 it should call handle_connect_event, 
otherwise if should call handle_expt_event.

Attached file prints "get exception" if asyncore can't connect to 
remote side, not "uncaptured python exception"

Patches from Issue1736190 do not fix this case.
