Thank you for your efforts and for investigating the issue! It's nice that you actually have tests and they seem to be catching issues (assuming the problem is not in the tests themselves).

Re: New egg: nng
Hi Mario! Welp... that's a bummer. I was sure it was a timing issue with the tests. I'll keep poking at it on different machines to see what I'm missing. Thanks for giving it a try! Cheers!

I'm sad to report, though, that tests of 0.2.1 still hang here. I'm testing it with the following command: $ test-new-egg nng https://gitlab.com/ariSun/chicken-nng/-/raw/main/nng.release-info I executed the command above three times and tests hanged consistently.

Re: New egg: nng
Thanks a lot! I have started using zmq (from Haskell) to implement some networking for a protocol and I was quite pleased with experience so far. Did not implement any form of authent or security though, as we don't really plan to use zmq as is in production. I was wondering whether or not it would make to port what I have to nng given it seems to have more traction nowadays. Having TLS support is indeed interesting.

Re: New egg: nng
Honestly, for my usecase, they are about the same. My main work with nng/zmq is implementing the actor model (I have two implementations, one for CHICKEN with nng, and a port for Common Lisp with zmq), so rep/req (and inproc pair for some sync when spawning an actor), nothing terribly complex. The main benefit and the reason that I personally like zmq more, is CurveZMQ, which saves me having to implement encryption with tweetnacl, for example. Sure, I have the tls transport with nng but that's a bit of a main imo. El 1 de noviembre de 2021 4:09:06 a. m.

Re: New egg: nng
I am currently using 0MQ (not in chicken though) and have been looking at nng for a while, but unsure how mature it is. What's your feedback using it? What are you using it for?

Re: New egg: nng
So, here's a followup I linked pthreads and added the things you suggested to the wiki. As for the hangs, I hate to say this but it seems like the test was the problem. More precisely, it seems like the topic for the subscriber socket wasn't set fast enough, so when the publisher socket sent a message, the subscriber wasn't ready for it. Hang. I added some coordination in the test itself and ran the tests over 100 times just to be sure. No hang. Maybe I'm just being extremely unlucky though, so as always feedback is appreciated. Just pushed a new tag with the changes, fingers crossed. On Sun, 31 Oct 2021 09:59:37 -0300 Ariela Wenner wrote: > Hi Mario! > > Thanks for the feedback!

Re: New egg: nng
Hi Mario! Thanks for the feedback! I'll be fixing the minor issues when I have time. As for the hang... yeah, damn. That's a bug I THOUGHT I had fixed but apparently not. It's weird that it only happens with pub-sub, and only sometimes. If anyone knows what might be going on hmu, help is immensely appreciated. I'll try re-submitting again after the issues are fixed.

New egg: nng
Hi all! I'd like to add my nng egg to the coop. Went through test-new-egg and everything seems fine. Release info is at https://gitlab.com/ariSun/chicken-nng/-/raw/main/nng.release-info Wiki page is http://wiki.call-cc.org/eggref/5/nng This is the first time I publish an egg so please let me know if something's wrong. Cheers!
