session (either +failsafe or normal). gsm_session_new() reads the appropriate autostart +and session files to create a list of GsmApps to be started. +(GsmAppAutostart represents an autostarted app, and GsmAppResumed +represents an app resumed from the previous saved session.) + +Startup is divided into 6 phases (GsmSessionPhase): + + * GSM_SESSION_PHASE_STARTUP covers mate-session's internal + startup, which also includes starting mateconfd and dbus-daemon (if + it's not already running). Mate-session starts up those + explicitly because it needs them for its own purposes. + + * GSM_SESSION_PHASE_INITIALIZATION is the first phase of "normal" + startup (ie, startup controlled by .desktop files rather than + hardcoding). It covers low-level stuff like + mate-settings-daemon and at-spi-registryd, that need to be + running very early (before any windows are displayed). + + Apps in this phase can make use of a D-Bus interface + (org.mate.SessionManager.Setenv) to set environment variables + in mate-session's environment. This can be used for things like + $GTK_MODULES, $MATE_KEYRING_SOCKET, etc + + * GSM_SESSION_PHASE_WINDOW_MANAGER includes window managers and + compositing managers, and anything else that has to be running + before any windows are mapped + + * GSM_SESSION_PHASE_PANEL includes anything that permanently takes + up screen real estate (via EWMH struts). This is the first phase + where things actually appear on the screen. + + * GSM_SESSION_PHASE_DESKTOP includes anything that draws directly + on the desktop (eg, caja). + + * GSM_SESSION_PHASE_APPLICATION is everything else (normal apps, + tray icons, etc) + +For each startup phase, GsmSession launches the appropriate GsmApps. +When apps connect to the XSMP or D-Bus servers, GsmClients are created +and added to the session. The session tries to map these clients to +GsmApps. GsmApps signal when they register (via XSMP or SN) or exit, +and GsmSession uses this to decide when the phase is complete. + +FIXME: after starting the session, we need to run the DiscardCommands +of resumed apps. + + +Running/Shutdown +---------------- + +GSM_SESSION_PHASE_RUNNING is pretty similar to the old mate-session; +mostly it just tracks XSMP clients, and watches for +SmRestartImmediately clients exiting (NOTE: THIS DOESN'T HAPPEN YET). + +GsmClient is in theory not XSMP-specific, but it's very very +XSMP-like, and the shutdown procedure is also very XSMP-like. This is +just because there's no way to do XSMP shutdown correctly otherwise. +However, GsmClientDBus will still be able to present a more sane +protocol to its clients than GsmClient presents to it. diff --git a/mate-session/gs-idle-monitor.c b/mate-session/gs-idle-monitor.c new file mode 100644 index 0000000..05dbb02 --- /dev/null +++ b/mate-session/gs-idle-monitor.c @@ -0,0 +1,507 @@ +/* -*- Mode: C; tab-width: 8; indent-tabs-mode: nil; c-basic-offset: 8 -*- + * + * Copyright (C) 2008 Red Hat, Inc. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
