Autosave doesn't work by default (no access to /tmp?)

[Chemrat]

Default temporary files folder doesn't seem to be set to anything. Apparently this defaults to /tmp, but --filesystem=host actually doesn't include this folder, see https://docs.flatpak.org/en/latest/sandbox-permissions.html#filesystem-access

This seem to result in silently broken autosave system (at very least blender coudln't generate quit.blend until I changed the path). Either manifest should include /tmp access or maybe default should point to some different folder? There must be some location flatpak apps are supposed to use for personal tmp dir (flatpak/flatpak#3438 seems to be related).

I will look into this soon... The (flatpak) recommended place for temporary files gets cleaned up once the application exits, so we will work a bit against the encapsulation here... But until now --filesystem=host has been in use so... :shrug: .

You'll be notified when i create a pull request to test a possible solution.

I've run into this issue too and it's pretty bad since it can result in a lot more lost work than needed.

Another solution is to change blender's temporary files directory to one you clean yourself. I have a script that regularly cleans ~/.local/tmp on my system, for instance. Setting it to that seems to have given me save recovery features again. Though it looks like the setting reset itself -- so it might not be very practical.

We can probably change the temp dir using environment variable.

Hi, I have add TMP and TMP_DIR env var to point to /tmp which is in /run/user/1000/.flatpak/org.blender.Blender/ for me. The tmp files does not get delete when Blender exit. Just update Blender and let me know if it work for you. Feel free to open this again if it does not work.

The same problem in fedora 38, i had created a simple text animation then after render (ctrl+f12) , the file doesn't save in the default output:/tmp. I had searched so many times with the file manager trying to find the file, but the file is not saved there.

Hi! This doesn't work...

Although now Blender can create quit.blend when exiting and this file exists after Blender quits, when Blender is opened again, the previous quit.blend file doesn't exist anymore. Looks like the /tmp dir gets cleared just before Blender's starting.

Hi, At this moment, I dont know what path it should be. Do you have some suggestion?

I changed the "Temporary File" Blender settings to /var/tmp and it seems to work. The file is actually saved to ~/.var/app/org.blender.Blender/cache/tmp.
