Description Benedikt Gollatz 2021-06-10 17:08:44 UTC 
Description of problem:

impressive segfaults in SDL when run on Fedora 34. This seems to be due to Fedora 34 including pygame 2.0.1, whereas Fedora 33 shipped pygame 1.9.6.

Version-Release number of selected component (if applicable):

impressive-0.13.0-0.6.20210107svn310.fc34.x86_64
python3-pygame-2.0.1-2.fc34.x86_64

How reproducible:

Always

Steps to Reproduce:
1. Run impressive on any file or directory with displayable content.
2.
3.

Actual results:

Segementation fault

Expected results:

A presentation.

Additional info:

Downgrading pygame to python3-pygame-1.9.6-9.fc33.x86_64 from Fedora 33 fixes the problem.
Comment 1 Michael J Gruber 2021-06-10 21:09:04 UTC 
Thanks for the report.

This is a crash in impressive's OpenGL loader, as soon as it tries to use SDL_GL_GetProcAddress on any GL function.

The version in F34 is the latest from svn already, which contains a commit supposedly making some things work with pygame-2.0.1 already. Upstream is pretty dead, though.

@gwync Do you have an idea what changed between pygame-1.9.6 and 2.0.1 in terms of GL loading? (I'm also wondering why impressive needs to do the loading manually, oh well....)
Comment 2 Gwyn Ciesla 2021-06-10 21:20:37 UTC 
I do not. Nothing jumped out at me in the changelog, or in my testing.
Comment 3 Fedora Update System 2021-06-12 10:45:23 UTC 
FEDORA-2021-48f1c98ad1 has been submitted as an update to Fedora 34. https://bodhi.fedoraproject.org/updates/FEDORA-2021-48f1c98ad1
Comment 4 Michael J Gruber 2021-06-12 13:13:36 UTC 
I'd like to emphasize that the update is made possible by a *very speedy* response from upstream! So, while the commit rate upstream might be slow, the contact is alive and well :)

The bug occured because impressive did not find SDL2 in Fedora - searching for SDL (due to a packaging error) lead to a seg fault, searching for SDL2 lead to an exception (due to a missing search path upstream). Both are corrected now.

pygame was not involved other than switching from SDL to SDL2 in pygame 2.0.*. While looking there, I noticed a few unrelated (and uncritical) issues which will be the subject of an upcoming PR.

Looking forward to a test report from the original reporter ;)
