Segfault in clock tree viewer

oharboe commented 9 months ago

Describe the bug

untar https://drive.google.com/file/d/19nK2MBVsMEgIc7n-mrFOWnPK6t5RBTnx/view?usp=sharing
Run ./gui.sh
Click around in the GUI and update clock tree viewer many times. After 2-3 minutes of trying, I can usually get it to crash.

are you modifying the design while 'clicking around'?

oharboe commented 9 months ago

are you modifying the design while 'clicking around'?

I didn't realize I could "modify" the design from the GUI. How do I do that? I'm just viewing things. Jumping between timing report, maybe rescaling, etc.

maliberty commented 9 months ago

The inspector allows limited changes (eg trash can icon). The tcl prompt allows anything

oharboe commented 9 months ago

The inspector allows limited changes (eg trash can icon). The tcl prompt allows anything

It crashes without that.

oharboe commented 9 months ago

@maliberty This crashes every time(though I don't think this is the only problem). Fix this first?

Select a square, yellow below
Click trashcan icon, crash

The image link is broken. I tried your steps above but got no crash.

The link worked on reload but the problem still doesn't reproduce

@maliberty So here is my best guess:

a render is triggered and the selected/highlighted list is duplicated for the low priority rendering thread
the main thread, higher priority, preempts rendering and deletes the elements on the selected/highlight list
the low priority rendering thread resumes and is now accessing deleted elements

I looked for, but could not find in RenderThread.cc:

a method to abort the current rendering and wait for it to complete
this method should be called before deleting/modifying what is being rendered
