Identify the "application/vnd.rar" MIME type in order to allow some operations
In order to solve Users are not able to browse rar files using Return (although it works for 7z, zip files, etc.), the Internet Media Type "application/vnd.rar" is recognized in KrArcBaseManager::getShortTypeFromMime(const QString &mime).
In https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Complete_list_of_MIME_types the type of rar files is "application/x-rar-compressed", but in the aforementioned page it's also declared that
IANA is the official registry of MIME media types and maintains a [list of all the official MIME types](http://www.iana.org/assignments/media-types/media-types.xhtml)
and precisely in that place what it's stated is "application/vnd.rar", with a link to
where it's written
- Deprecated alias names for this type: application/x-rar-compressed
Note: "application/vnd.rar" is already used in Krusader, in KrServices::generateKrarcArchiveMimetypes().
The text "application/x-rar;application/x-rar-compressed;application/vnd.rar" can be searched in https://github.com/lxde/libfm/blob/master/data/archivers.list
In Kubuntu 18.04 I executed:
$ xdg-mime query default application/x-rar org.kde.ark.desktop $ xdg-mime query default application/x-rar-compressed org.kde.ark.desktop $ xdg-mime query default application/vnd.rar org.kde.ark.desktop $ xdg-mime query default application/vnd.JUST_TO_CHECK_THAT_IT_CAN_FAIL; echo $? 4
Several people had a similar problem when using other programs (https://bbs.archlinux.org/viewtopic.php?pid=1748314#p1748314 , https://github.com/webmin/webmin/issues/702#issue-276713752).
FIXED: [ 411330 ] Users are not able to browse rar files using Return (although it works for 7z, zip files, etc.)
