[Python-Dev] Return error codes from getaddrinfo. (original) (raw)

Dear all,

I'm seeking enlightenment on the error codes returned by the socket.getaddrinfo() function.

Consider the following on python 2.5 on Windows

import urllib urllib.urlopen("http://nonexistent") [snip traceback] IOError: [Errno socket error] (11001, 'getaddrinfo failed')

So the error number is 11001.

But when I try to find a symbolic constant in the errno module corresponding to this error number, I can't find one.

import errno errno.errorcode[11] 'EAGAIN' errno.errorcode[11001] Traceback (most recent call last): File "", line 1, in KeyError: 11001

Looking through the C source for the socket module doesn't provide any clarity (although my C is a little rusty). That module has a special function, set_gaierror(), for handling error returns from getaddrinfo. But I can't see if or how the resulting error codes relate to the errno module.

Is there supposed to be symbolic constants in the errno module corresponding to getaddrinfo errors?

I want jython to use the same errno symbolic constants as cpython, to ease portability of code.

Regards,

Alan.
