[Openmcl-devel] bug with usocket and/or trunk ccl - "error #22"

Wed May 20 18:25:04 UTC 2015

Hi,

I was working on this issue since 10 hours ago when I firstly saw the mail. I’ve already committed an initial fix [1] to usocket Git master, in which I handled two compatibility issues between usocket and ccl-1.11, and now there’s no error reported when creating and sending sockets. But it seems that CCL::SEND-TO cannot actually send out the data to a “connected” UDP socket, as a result the test code is blocked at (usocket:socket-receive …).

Usocket’s backend code for CCL is basically just a wrapper (even more true for ccl-1.11), my next step is to remove all usocket wrappers and only use CCL’s native API to reproduce the same issue. I’ll submit trac tickets to CCL if I found something.

Regards,

Chun
