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 "<stdin>", line 1, in <module>
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.
