From 0d6c7518d2cd66ba15ca7b8628d7b1e40e9ba875 Mon Sep 17 00:00:00 2001 From: Jasmine Hassan Date: Fri, 14 Dec 2012 21:38:42 +0200 Subject: [housekeeping] Use g_settings_get_mapped, fix paranoid cleanup on shutdown 1. Use g_settings_get_mapped instead of our own hack get_gsettings_int_with_default. 2. Don't force hard-coded default when value is 0, as that's used to allow paranoid scanning on shutdown. 3. Only unref the settings object at the end of _stop routine, not before do_cleanup is potentially called, since purge_thumbnail_cache uses the settings. This was also causing asserts when killing msd, as described in (now closed) #23. These are regressions introduced by the gsettings port of the plugin -- 03478b4d --- plugins/housekeeping/msd-housekeeping-manager.c | 106 ++++++++++++++---------- 1 file changed, 62 insertions(+), 44 deletions(-) (limited to 'plugins') diff --git a/plugins/housekeeping/msd-housekeeping-manager.c b/plugins/housekeeping/msd-housekeeping-manager.c index e9e27c9..cbb1143 100644 --- a/plugins/housekeeping/msd-housekeeping-manager.c +++ b/plugins/housekeeping/msd-housekeeping-manager.c @@ -1,5 +1,6 @@ /* * Copyright (C) 2008 Michael J.
