From: Michal Privoznik <[email protected]>According to [1] there are only few characters allowed in the path to the daemon socket (alphanum and some punctuation; notably, space is missing on the list). The rest must be escaped by '%NN' notation. Fortunately, g_uri_escape_string() with some carefully selected input values is able to escape the path.
Almost - it considers tilde valid but DBus doesn't. Well, let's hope nobody has tilde in domain name.
https://www.rfc-editor.org/rfc/rfc3986.html#appendix-A Well, g_uri_escape_string does what it says: unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~" Whether dbus is wrong or not, libvirt should escape the tilde too. Jano
