What is the related issue number (starting with #)
N/A

What is the current behavior? (You can also link to an open issue here)
In win32.py's ConsoleCtrlHandler, if start/stop is called multiple times, this is logged at the ERROR (40) level.

What is the new behavior (if this is a feature change)?
If start/stop is called multiple times, this is logged at the INFO (20) level.

Other information:
Since the code handles the situation well, and there are no side effects to multiple calls, we shouldn't pollute the logs with error level entries.

Also, because ConsoleCtrlHandler is extremely proactive at removing itself (when it captures Ctrl+C or equivalent), even before it attempts to stop the bus, it sometimes ends up that the handler's stop is called multiple times (directly, then via a 'stop' publish event) during normal operations. There's no inherent badness to this, so while it should be noted/logged, it should be logged at a much lower level.

Hi, any update on this? Is there any additional work/discussion required?

[webknjaz]

I've restarted tests, will merge after success

[robinchow]

I scanned the failed builds, and I don't see anything that links the failed tests to this code change. I could be wrong though, happy to fix up someone points me in the general direction.

[webknjaz]

Yeah, TravisCI build got fixed upon restart

[webknjaz]

Thanks!
