[zeromq-dev] [PATCH] issue 211, REP socket futzing

[Pieter Hintjens]

Martin,

Attached is a patch against 3.0 master that fixes, afaict, the
assertion failure in REP sockets when they get messages lacking an
envelope.

The issue is here: https://github.com/zeromq/libzmq/issues/211

The code doesn't close the connection, but it does discard the message
and leave the state machine in the correct state. Tested with one
valid client doing requests in a loop, and an invalid client trying to
futz socket in parallel.

Also done on 2.1 and 2.2, so no downstreaming required.
