>          Components: proton-c
>    Affects Versions: 0.8

>         Attachments: connect.patch
> The majority of errors that can occur on a call to connect(...) (timeout, 
> host unreachable, network unavailable, etc) are hidden by the io layer. The 
> reason being that the socket is set to non-blocking prior to the call to 
> connect and the result of the connect is never checked.
> A possible fix can be found here:

> This fix make the pn_connect function block by using select to check the 
> result of connect with a timeout (currently 10 sec). Another option would be 
> to be to set the socket to non blocking after the connect, but this can can 
> cause connect to block for minutes.
