Hi, I'm running Debian stable with KDE.
I have a question about the way applications are associated with file types. Based on this documentation [1], I understand that: - The associations are derived from *.desktop files located in /usr/share/applications and subdirectories. - A program called 'update-desktop-database' builds a cache of mappings from file types to applications in the file /usr/share/applications/mimeinfo.cache. - The associations can be customized using a file mimeapps.list. My questions are: (1) If the 'update-desktop-database' program has not yet been run on a system, so there is no mimeinfo.cache file, are programs that want to query the default application for a file type expected to look into the *.desktop files manually? I ask this because I'm finding that, for example, GLib, which provides an API to query the default application for a file type [2], does not look at the *.desktop files itself if there is no mimeinfo.cache file. (2) If the answer to (1) is 'no', should something be automatically running 'update-desktop-database' upon system installation and after a new application is installed? It doesn't seem like something the end-user should have to do to get correct associations. Thanks, Nate [1] https://wiki.debian.org/MIME#Application_association [2] https://developer.gnome.org/gio/stable/GAppInfo.html#g-app-info-get-default-for-type
