List of steps to reproduce:
- Set $wgLogo to something like "/thumb.php?f=Wiki.svg?width=120"
- Create similar entries for $wgLogoHD
- Load the wiki and observe that the logo appears
What happens?:
Check the logs for messages like "failed to hash .../thumb.php?f=Wiki.svg?width=120" from OutputPage::transformFilePath()
Over time the log will fill with these superfluous messages.
What should have happened instead?:
MW should recognize that this is not a file and not try to use md5_file on it.
