Raw Blame History

From 14bb1237f71e38749558c74963032a0387eecec0 Mon Sep 17 00:00:00 2001
From: Ray Strode <rstrode@redhat.com>

Subject: [PATCH 2/2] user: export new Saved property
accountsservice maintains a state file for some users, if those users
have selected a specific session or language.
There's no good way, at the moment, for an application to check if a
specific user has saved state.
This commit exports the Saved property on the User object.

The login history for this user.
Each entry in the array represents a login session. The first two
