[zeromq-dev] Udp on Travis errors?

[Arnaud Loonstra]

Hey all,

I think we have some issues with UDP on travis. For example the 
zbeacon_ipv4_mcast_test is skipped because it can't open the UDP socket. 
(sock == INVALID_SOCKET)

On some occasions zbeacon also fails with:
* zbeacon: D: (czmq_selftest) 20-07-16 08:00:20 zsys_udp_send: failed, 
reason=Operation not permitted

D: (czmq_selftest) 20-07-16 08:00:20 zbeacon: failed to transmit, 
attempting reconnection. reason=Resource temporarily unavailable

however the test still succeeds then. Somebody made this work apparently?

Anyhow, I was working on a new zudp class which was on the czmq's todo 
list. Although tests are working on my machine they don't on Travis.

Anybody experience with travis and udp/ipv6?

See the zudp branch here: 
https://github.com/sphaero/czmq/blob/zudp/src/zudp.c#L394

The failing travis here: 
https://travis-ci.org/github/sphaero/czmq/jobs/708640774#L1895

Feedback on the zudp class is also welcomed!

Rg,

Arnaud
