[issue19044] getaddrinfo raises near-useless exception

Well, as Ned explained, that's a libc bug.
If getaddrinfo() fails with EAI_SYSTEM, errno should be set.

There's nothing more Python can do.
If the error is reproducible, you can run the failing code with strace, to see 
what's going on (and check if there's a more recent glib version which could 
fix this bug).

[issue19044] getaddrinfo raises near-useless exception

2013-09-18 Thread Nikolaus Rath 

New submission from Nikolaus Rath:

I received a bugreport for a Python application that contains the following 
stacktrace:

   File /usr/lib/python3.3/http/client.py, line 1057, in endheaders
 self._send_output(message_body)
   File /usr/lib/python3.3/http/client.py, line 902, in _send_output
 self.send(msg)
   File /usr/lib/python3.3/http/client.py, line 840, in send
 self.connect()
   File /usr/lib/python3.3/http/client.py, line 1194, in connect
 self.timeout, self.source_address)
   File /usr/lib/python3.3/socket.py, line 417, in create_connection
 for res in getaddrinfo(host, port, 0, SOCK_STREAM):
 OSError: [Errno 0] Error

My guess is that something went wrong with the name resolution, but it seems 
near impossible to handle this in the application because apparently the 
exception contains no machine usable useful informaton at all. 


It would be nice if whatever information Python used to determine that the 
getaddrinfo call failed could be included in the exception, so that it can be 
properly caught and handled.

2013-09-18 Thread Ned Deily 

Ned Deily added the comment:

This looks like a platform bug. What platform was this running on?  A web 
search turns up other reports of the system getaddrinfo() returning errno = 0 
due to a glibc bug, for example, 
https://bugzilla.redhat.com/show_bug.cgi?id=958652.
