(Reposting #1970 which was mistakenly posted anonymously)

Reading source at tag gazebo7_7.1.0

gazebo / common / Events.hh 298-304 defines events for simulation "stop", "step" and "pause".

gazebo / physics / World.cc 155 even connects a handler to the "step" event.

However in the entire source tree I couldn't find a single call to event::Events::step(), meaning that the event is probably never triggered.

In fact, the step handler routine in World.cc is being called directly from World::OnControl() (line 1295), bypassing the event mechanism entirely.

The same applies to the "stop" event except that it's neither hooked nor triggered by any code.

I suppose that events were put there in the first place to allow plugins to hook them, but this is rather pointless when they're never triggered.
