context.terminate hangs #122

Closed smrt28 closed 7 years ago

smrt28 commented 7 years ago

There is nothing listening on localhost:42556. This code hangs in context.terminate:

require 'ffi-rzmq'
context = ::ZMQ::Context.new(1)
sender = context.socket(::ZMQ::REQ)
sender.setsockopt ::ZMQ::LINGER, 1
sender.setsockopt ::ZMQ::RCVTIMEO, 1000
sender.setsockopt ::ZMQ::SNDTIMEO, 1000
sender.connect 'tcp://localhost:42556'
context.terminate

This isn't a problem with ffi-rzmq. You are misusing the zeromq library. If you wrote the same code in C it would also hang.
