Code profiling does nothing

General

Is there any way to find out why code profiling doesn’t do any result on my main project? Smaller projects work fine. The important project doesn’t give me a profiling result. I can see the quit menu handler executing. And then nothing.

Xojo 2020r2.1 on High Sierra

Two things that I am aware of which can prevent it.

  1. If the application is in the App Sandbox.
  2. If you’re using the terminate declare to quit your application (probably called terminate in MBS too).

All the time…
No sandbox, no terminate declare.

Oh.

Yup

<https://xojo.com/issue/64150>: When profiling if no profile data can be collected give information why

This is probably doing to be implemented in the next decade. Told the user to install XCode. :slightly_frowning_face:

You don’t have a call to StopProfiling in your app anywhere do you?

That was the first thing I checked.

Is it possible your app is actually crashing at quit, but the quit is masking it?

Got it. Some users had problems with quitting and for those I had added a terminate. This interfered with profiling.

For the sake of completeness, Remote Debugging can also be a reason.

Huh… I didn’t know that.

Isn’t it possible to add a warning at IDE run time, something like:

"Your project use remote debugging, Exterminate, etc…”. “Code profiling do not works under these conditions…”

before running the application…

and with two buttons: “Cancel” and “Continue without Code Profiling”…
