Stop polluting filesystem (replay)

This still has issues @strk. You don't check to see if that folder exists anywhere, neither is it ever cleaned up. You're trading proper operating system temporary file handling for storing everything in some custom location which is NEVER cleaned up.

Given CI is green, may I ask you to give more details about what fails ? Note I filed at least 14 tickets about non-working testsuite when run locally but most of the times those issues are disregarded because "CI works!". I'm happy to improve offline testsuite experience but I need more details about what is not working for you.

So: how exactly those missing checks break the run for you ? Could you see a way to encode those situations in the CI so I can get a red here instead of a green ?

Hi, as we are building qgis on a mutliuser basis on the same big-cpu-ram server, we encounter issues with the mixed up of temp files in the /tmp. As our different users build different branches, we cannot use the same user for everyone. And tests fail due to conflicts on the files generated by tests owned by different users.

Do you have some updates about the last remaining issues? Do some tests are still failing?

Regards
