XSUB "support"

[mhaberler]

we have some interest in an embedded client which would need to do both DEALER and XSUB (NB @zhivko)

it turns out the dealer socket works just fine with an XSUB publisher, see testxsub.c in https://github.com/mhaberler/libzmtp/commits/xpub

happy to take recommendations what to do with this

I see how I could do a ROUTER pthread for a dealer selftest
I do not see how I could do a XPUB pthread - unclear how to manage subscriptions

is it worth writing zmtp_router.c, zmtp_xsub.c classes?

Hi Michael, I think it makes perfect sense to add support for XSUB socket type. is it your idea to contribute patches for this?

[mhaberler]

fine - it's just that it will be a rather boring copy & paste job on zmtp_dealer.c with renamed methods - plus subscribe/unsubscribe methods

if that is OK I'll do it and give it a stab at selftests

[hurtonm]

yes, but often that creates an opportunity to refactor existing code base and that usually is rewarding experience
