Update to use XDG cache home for thumbnails (1.48 KB, patch)
2012-04-30 16:51 UTC, William Jon McCann 		reviewed Details | Review

Description William Jon McCann 2012-04-30 16:18:15 UTC 
We are in the process of updating the Thumbnail spec to change the cache
location from ~/.thumbnails -> $XDG_CACHE_HOME/thumbnails.

./glib/gio/glocalfileinfo.c needs to be updated.

Review of attachment 213121 [details] [review]:

Should we check for the existence of ~/.cache/thumbnails and fall back if it doesn't exist ?

I guess this depends on whether we end up migrating existing thumbnails to the new location or not. Since the gnome-desktop patch doesn't seem to do it, we should probably fall back...it would also make things work better in case mixed versions of gnome-desktop and glib are used.

I decided to keep it simple for now and just push the patch as-is
Comment 5 Jussi Kukkonen 2014-01-08 13:08:43 UTC 
Rygel (with MediaExport backend) is now basically broken because
 * GLib tells Rygel the thumbnail does not exist
 * Rygel tells Tumbler to generate the thumbnail
 * Tumbler will re-generate the thumbnail in a location where GLib (and by
extension Rygel) won't find it
So we're burning a lot of cycles and still not showing any thumbnails :(


Was there any plan on how systems should have been upgraded? Are distros supposed to do symlinks ($HOME/.thumbnails -> $XDG_USER_CACHE/thumbnails) until all software is updated to the new directory, or where do I need to file bugs about it?
