[zope2-tracker] [Bug 1097817] [NEW] gaierror: [Errno 9] servname not supported for ai_socktype While starting zeo client

[Mordicus et Cubitus]

Public bug reported:

I've encountered this error today while starting Zeo client on FreeBSD
7.0 after having installed Plone with Unified installer for version
4.2.1 (Python 2.7 and Zope 2.13.16

gaierror: [Errno 9] servname not supported for ai_socktype


Regarding my google friend advice : http://code.google.com/p/py-amqplib/issues/detail?id=41 I have updated the line 446 of ZEO/zrpc/client.py like this:


-                      ) in socket.getaddrinfo(host or 'localhost', port):
+                     ) in socket.getaddrinfo(host or 'localhost', port, 0, socket.SOCK_STREAM):

This has solved the defect.

If this can help creating a work around to this issue. Or if you have
another suggestion I'll be glad to know it.

With kind regards,

Gaël.
