Description

Running a mime type detection on .xz archive files returns an incorrect mime type.

This code:

$path ="[Path to .xz file]";$finfo =new \finfo(FILEINFO_MIME_TYPE);$mimeData =$finfo->file($path);echo$mimeData;

Resulted in this output:

"application/octet-stream"

But I expected this output instead:

"application/x-xz; charset=binary"

This is apparently an issue with libmagic version 5.40 and was fixed in 5.41 (refhttps://bugs.astron.com/view.php?id=257).
The specific fix to the magic file can be found here:file/file@9b0459a

I suggest a similar fix toGH-8805 that was done in34fa65a, since the issue seems very similar.
