Clear any theming prefixed cache on cache buster increase

[juliusknorr]

Regression from #8716, where the baseUrl was added to the theming cache prefix. When clearing on cache buster increase, the cache was not cleared properly, because it was missing the baseUrl.

This PR will make sure we clear cached values for any baseUrl prefix.

Fixes #8888

Also requires to be backported to 13.

I guess out acceptance tests didn't catch that, since they are not running with any cache backend.

so i just need to replace the file ? sorry for that question ..

[ExaconAT]

Don't know

[juliusknorr]

@mairsebastian @ExaconAT You can just change the line in apps/theming/lib/ThemingDefaults.php as shown in the diff: https://github.com/nextcloud/server/pull/8983/files#diff-5ba7c2fd4066c431ab229e984115f9b6

[mairsebastian]

hello @juliushaertl i dont have this file or this Directory "test"

apps/theming/tests/ThemingDefaultsTest.php

[mairsebastian]

sry me again, after changing the first line, nextcloud is not working anymore. any ideas?

[juliusknorr]

@mairsebastian You should restore the file from originally installed zip archive. When you try to patch your Nextcloud instance, you can ignore the ThemingDefaultsTest.php file. All it requires is to change one line in apps/theming/lib/ThemingDefaults.php to get rid of the 'getScssVariables' method argument.
