[zeromq-dev] about Assertion failed: !more (src/fq.cpp:117): just remove the assertion?

[zmqdev]

Hi,

Ranjeet Kumar described his troubles with the assertion in

http://lists.zeromq.org/pipermail/zeromq-dev/2016-September/030839.html

According to

http://lists.zeromq.org/pipermail/zeromq-dev/2016-September/030851.html

he apparently solved his problem by commenting the assertion out.

1. Could someone who understands that part of the code advise on the
safety of removing that assertion?

2. Is the assertion even correct?

Thanks

[Doron Somech]

It don't think it is correct, there might be an issue we need to solve.

The workaround is not to use multi-part messages...

Also I think it smells like using socket from multiple threads...

unfortunately no, the assertion strikes in a single thread application.

See also the test case at

I like multi-part messages!

The workaround would require me to do the framing myself, which would be
tricky, considering the advanced state of the application.


Thanks anyway.

I actually those are different issues. If you suffer from the pubsub
issue, I think I trace the bug and have a solution. Take a look at the
issue. If you suffer from the 100K issue, I think that is a different
one, anyway you can try the solution as well. It might be related to
another pipe.terminate call

just tweaked the test case of issue 2163 for a message with a single frame.

No assertion, the program completes.

There seems to be something broken in PUB -> SUB, multi-part messages,
and zmq_disconnect.

Try compile zeromq with the tweak I suggested and the multipart test case.
