Re: [reSIProcate] Patch for rutil

[Karlsson <boost.regex@xxxxxxxxx>]

Hi Daniel, in the udp.cxx, the UDP socket is works in blocking mode, the recvfrom will always wait if no data is received, it's never return if the STUN server is not respond or it is down.

In my patch the UDP socket is set a timeout option, and it will trying three times once the sendto/recvfrom returned by timeout.

I'm not write the test case, it's just works fine in my project.

Best regards,

Hi Karlsson,

Did you find any test case which tests this class or do you think it
would be very difficult to create such a test case that simulates the
bug (e.g. by referring to an IP that is deliberately blackholed)

On a more general note, some test cases like that would potentially need
a local environment configured to simulate certain problems and may not
be valid in CI (on travis-ci.org).  We could use some environment
variable to specify whether such test cases run or not.

Regards,

Daniel
