bug #33960 [DI] Unknown env prefix not recognized as such (ro0NL)
This PR was submitted for the 4.3 branch but it was merged into the 4.4 branch instead. Discussion ---------- [DI] Unknown env prefix not recognized as such | Q | A | ------------- | --- | Branch? | 4.3 | Bug fix? | yes | New feature? | no | Deprecations? | no | Tickets | Fix #... <!-- prefix each issue number with "Fix #", if any --> | License | MIT | Doc PR | symfony/symfony-docs#... <!-- required for new features --> This is a failing test to illustrate the difference between real and fake env vars when using an unknown prefix, followed by the `default` prefix. ``` %env(unknown:default::REAL)% // Unsupported env var prefix "unknown". %env(unknown:default::FAKE)% // null ``` For `default::FAKE` we get `null` at38b9a27976/src/Symfony/Component/DependencyInjection/EnvVarProcessor.php (L103)
which is then preserved at38b9a27976/src/Symfony/Component/DependencyInjection/EnvVarProcessor.php (L123)
need inspiration for a patch still :) Commits -------550819a655
