Issue #4243 Crash: when using Draft Facebinder

Post by vocx »

Now it's issue #4243.
  • Open FreeCAD, open a new document, go to the Part Workbench, and create a simple Part Box.
  • Switch to the Draft Workbench.
  • Press the Draft Facebinder button, then select the top face of the Cube. A Facebinder object is created.
  • Click anywhere in the 3D view to de-select the newly created object.
  • Again click on the Draft Facebinder button, and try picking the face of the Cube again. As soon as the mouse pointer leaves the toolbar area, and enters the 3D view again, the program crashes.

Code: Select all

Select face(s) on existing object(s)
Select face(s) on existing object(s)
<class 'TypeError'>

Re: Crash: when using Draft Facebinder

Post by vocx »

I originally tested this bug with a Debug version, that is, a self-compiled version with -DCMAKE_BUILD_TYPE=Debug, but it works the same if using a regular version. Now it's issue #4243.
  1. Open FreeCAD, open a new document, go to the Part Workbench, and create a simple Part Box.
  2. Switch to the Draft Workbench.
  3. Press the Draft Facebinder button, then select the top face of the Cube. A Facebinder object is created.
  4. Click anywhere on the 3D view to de-select any object.
  5. Again click on the Draft Facebinder button, and try picking the face of the Cube again. As soon as the mouse pointer leaves the toolbar area, and enters the 3D view again, the program crashes.
Sometimes there is no crash when pressing Draft Facebinder the second time and entering the 3D view. In this case you can pick any face of the Part Box and nothing will happen. The task view will just stay there open only with the "Close" button showing.

So press the "Close" button to finish the operation. Then choose Draft Facebinder a third time, and when moving the pointer to the 3D view, this time a crash is almost guaranteed.

As shown in the backtrace, probably the issue is in the callback mechanism of the Facebinder command. This is shown in the call stack at around #30 to #50 depending on how deep the calls are.

Code: Select all

Select face(s) on existing object(s)
Select face(s) on existing object(s)
Select face(s) on existing object(s)

Re: Issue #4243 Crash: when using Draft Facebinder
