Nick Burch commented on TIKA-3686: ---------------------------------- Detecting types of text-based files with magic is always going to fail for some cases. There are no sure-fire things to match on, only guesses If you're sure that your files have the right extensions on them, just ask Tika to detect by filename only, no contents > CSS file detected as JavaScript (application/javascript) > -------------------------------------------------------- > > Key: TIKA-3686 > URL: https://issues.apache.org/jira/browse/TIKA-3686 > Project: Tika > Issue Type: Bug > Components: detector > Affects Versions: 2.0.0-ALPHA > Reporter: Marius Dumitru Florea > Priority: Major > > The following CSS file > [https://github.com/techlab/jquery-smartwizard/blob/v5.1.1/dist/css/smart_wizard_all.min.css] > is detected as {{application/javascript}} using: > {noformat} > TikaUtils.detect(InputStream stream, String name) > {noformat} > The reason seems to be that the CSS file starts with: > {noformat} > /*! > * jQuery > {noformat} > which matches the "jQuery" entry from > [tika-mimetypes.xml|https://github.com/apache/tika/blob/2.3.0/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml#L348] > used by Tika's {{MimeTypes}} detector. > This is a regression introduced by > https://github.com/apache/tika/commit/97699598f000139b1222b785d634b3c8a8e216c7 > in TIKA-1141 (2.0.0-ALPHA). > The implications are serious if the mime type returned by Tika is used to set > the content type on the HTTP request returning the CSS file to the browser: > the browser ignores the CSS. > FTR, in my case the CSS file is not served directly from the file system but > from a WebJar (in this case > https://search.maven.org/artifact/org.webjars.npm/smartwizard/5.1.1/jar ) and > we're using Tika to determine the type of files requested from the WebJars. -- This message was sent by Atlassian Jira (v8.20.1#820001)
