* Switch from unmaintained paperclip to kt-paperclip * Drop some compatibility monkey-patches not required by kt-paperclip * Drop media spoof check monkey-patching It's broken with kt-paperclip and hopefully it won't be needed anymore * Fix regression introduced by paperclip 6.1.0 * Do not rely on pathname to call FastImage * Add test for ogg vorbis file with cover art * Add audio/vorbis to the accepted content-types This seems erroneous as this would be the content-type for a vorbis stream without an ogg container, but that's what the `marcel` gem outputs, so… * Restore missing for_as_default method * Refactor Attachmentable concern and delay Paperclip's content-type spoof check Check for content-type spoofing *after* setting the extension ourselves, this fixes a regression with kt-paperclip's validations being more strict than paperclip 6.0.0 and rejecting some Pleroma uploads because of unknown extensions. * Please CodeClimate * Add audio/vorbis to the unreliable set It doesn't correspond to a file format and thus has no extension associated.
