Hey all,

GNU Radio 3.7.7.1, Ubuntu 14.04

Thank you Nathan for giving me that paper on Performance Counters and Control Ports. That is exactly the kind of debug analysis I want to do.

I remember a long while back control ports had to be disable, I don't remember why. My install seems to fail with a CtrlPort Monitor in my flowgraph (AttributeError: 'NoneType' object has no attribute 'endpoints'). Is this because they are still disabled, or should I look into fixing my install?

Thanks,

Rich

Nope, ControlPort was put in after 3.7.7 (and 3.7.7.1). It is enabled on Master and will be released with 3.7.8.

We reimplemented the backend using Thrift, and there were too many uncertainties with it when we were ready with 3.7.7, so we decided to leave it out. It's now in master for those wanting and able to test it.

I've also used it on Android-based GNU Radio apps to optimize performance, which gives me a lot of confidence about it.
