small bug: trace points in commented code

Hi,

I think I found a small bug:

if you comment out code, that still has trace points set, they will be executed although the underlying code is not executed. One has to explicitly disable or delete the trace points and recompile.

Nevertheless: great product!

Jürgen

Thanks,

Yes because we inject serial.print statements for breakpoints you can put a BreakPoint on empty and commented lines and they will still work. 

All comments are converted to spaces when making a debug compile which avoids the need for the injection system to be concerned with them.


This is quite useful for new users but a little strange or confusing for experienced.

We are listening to feedback to decide if this should be allowed or now. It's not an easy decision  Smiley

Thanks for the fast reply!

To be honest, I would even find it confusing for beginners, because commented code should not produce any side effects.

Another point is that I frequently use #ifdefs for different builds and testing configurations. So if I #ifdef out a test routine, it will still produce the debug output which may slow down my programm...

But that are just my 2 cents...

Valid points but if a new user has an empty function, adds a breakpoint then runs the debugger they still get to see that the function is hit.

However maybe can have a half way solution? Breakpoints on comments should be ignored, breakpoints on empty code lines can be executed?

As concerns the #define, the breakpoint should be ignored by the compiler as normal?

Thanks
