It talks the +standard X11R6 session management protocol (XSMP). Thus, in theory, +it should be compatible with all session managment compliant X11R6 +applications. Unfortunately, there aren't that many of them. To be +precise, I have never seen a single commercial application that +supports it and even within the official X11R6 distribution, 'xclock' +is the only exception. Nevertheless we've chosen to support XSMP +despites the complexity of the protocol in order to provide KDE users +more interoperability with applications that were not explicitely +written with KDE in mind. XSMP, as an official X standard, promised to +be more likely to be supported by third parties than even a superior +KDE-specific protocol. Let's see whether we were right and more +applications will actually talk XSMP. At least all KDE applications do +now. + +Here's a short overview on how session management works. + +Starting the server +------------------- + +The server is usually started from the 'startkde' script. It supports the following options: + + -r, --restore Restores the previous session if available + -w, --windowmanager <wm> Starts 'wm' in case no other window manager is + participating in the session. Default is 'kwin' + +The default 'startkde' launches 'ksmserver --restore'. The +'windowmanager' option is useful for users that prefer a window +manager other than kwin. Since the window manager has to participate +in the session (it has to remember window positions and states), it is +usually restarted when the session is restored. To be *really* sure +that this happens, even if the wm might have crashed during the +previous session, ksmserver ensures that. The option specifies, which +windowmanager shall be launched for sure. But again: if the stored +session contains a window manager, the restored one will be used, not +the specified one. As a special feature, ksmserver always starts the +specified window manager first, which results in a much nicer startup +sequence (less flashy). + +KDE startup sequence +-------------------- + +Ksmserver controls the second part of the KDE startup sequence, +after it gets control from the startkde script, which controls +the first part of the startup sequence. All code related to startup +should be in startup.cpp and going down in that source file should +follow the startup order (but note that this is just a documentation +which may get outdated, so in case of doubts the source wins ;) ). + +The startkde scripts already launches kdeinit, which in turns launches +KDE daemons like dcopserver, klauncher and kded. Kded loads autoloaded +kded modules, i.e. those that have X-KDE-Kded-autoload=true in .desktop +files. The exact way autoloading works is controlled by X-KDE-Kded-phase=, +which may be 0, 1 or 2 (the default). Kded phase 0 means the module is +always loaded by kded, even outside of KDE session. It should used only +by kded modules which must be always running. Kded phase 1 modules are +loaded right after kded startup, but only during KDE startup, i.e. it is +for modules that are always needed by the KDE session. Phase 2 modules +will be loaded later. + +Startkde also launches kcminit, which performs initialization done by kcontrol +modules. There are three kcminit phases, 0, 1 and 2, controlled +by X-KDE-Init-Phase= in the .desktop file, which defaults to 1. Phase 0 kcminit +modules should be only those that really need to be run early in the startup +process (and those should probably actually use kstartupconfig in startkde +to be done even before kdeinit and daemons). After executing phase 0 +modules kcminit returns and waits. + +When ksmserver is launched, the first thing it does is launching +the window manager, as the WM is necessary before any windows are possibly +shown. When the WM is ready, ksmserver tells klauncher to perform autostart +phase 0 ($KDEHOME/share/autostart). There are 3 autostart phases, 0, 1 and 2, +defined by X-KDE-autostart-phase, defaulting to 2. Phase 0 is reserved only +for the actual visible base components of KDE, i.e. KDesktop and Kicker, +in order to make the startup appear visually faster. Both KDesktop and Kicker +use DCOP calls suspendStartup() and resumeStartup() to make ksmserver stay +waiting for autostart phase 0 until both KDesktop and Kicker are ready. + +Next step is telling the waiting kcminit to perform phase 1 - all kcminit +modules that should be executed before KDE startup is considered done. +After that ksmserver tells klauncher to perform autostart phase 1, +i.e. launching normal components of KDE that should be available right +after KDE startup, and after this session restore is performed, +i.e. launching all applications that were running during last session +saving (usually logout). + +By this time KDE session is considered to be more or less ready and +ksmserver does the knotify startkde event (i.e. plays the login sound). +It also tells klauncher to perform autostart phase 2, kded to load all +remaining autoload (i.e. kded phase 2) modules, kcminit to execute +kcminit phase 2 (kcontrol modules that do initialization that can wait, +like launching daemons) and kdesktop to execute the user Autostart folder. + +Technical note: There's a reason why kded modules and items in autostart +default to the latest phase. Before you explicitly use a different phase, +read and understand what's above. You should also consider whether something +really needs to be launched during KDE startup and can't be loaded on-demand +when really needed. Abusing the phases will result in public spanking +for making KDE startup slower. + + +Establishing the connection +--------------------------- + +As required by the XSMP specification, the session management server +propagates its network address in the SESSION_MANAGER environment +variable. Probably not the best way to do it, but it's the way it +is. All KDE (and plain Qt) applications simply read this variable and +try to establish a connection to an XSMP server at this address. If +the variable is undefined, nothing happens. + +This means, if you want to start a program that should not participate +in the session, simply undefine SESSION_MANAGER in your terminal +window and launch the application. If you want to see an application +desparately trying to connect to something, try setting it to some +bogus value. + +In addition, ksmserver propagates both its network address and its +process id in ~/.kde/socket-$HOSTNAME/KSMserver-$DISPLAY. A +utility function KApplication::propagateSessionManager() reads this +setting and sets SESSION_MANAGER accordingly, so that child processes +can pick it up. The function is called by clients that are started +outside the session ( i.e. before ksmserver is started), but want to +launch other processes that should participate in the session. +Examples are kdesktop or kicker, see below. + +Authorization +------------- + +XSMP is, just like DCOP, built on top of the Inter Client Exchange +(ICE) protocol, which comes standard as a part of X11R6 and later. +Authorization is done using 'iceauth', with MIT-MAGIC-COOKIE as used +by X. In order to be able to access the session management server, you +need to be able to read ~/.ICEauthority. For security reasons, we do +not provide any host-based authorization (neither does DCOP, btw.). + + +Requesting a shutdown +--------------------- + +If an application wants to request a shutdown (i.e. a logout), it does +this via an SmcRequestSaveYourself message to the server. In KDE, a +utility function KApplication::requestShutDown() does exactly +this. It's for example called by KDE's panel or by the context menu of +the desktop. + + +User Interface +-------------- + +ksmserver has a very straight-forward user interface. It mainly asks +the question "Shutdown KDE Session?" and provides two obvious command +buttons "Yes" and "Cancel". The interesting bit is the additonal +checkbox that says "Restore session when logging in next time". The +checkbox remembers state within session, so simply use whatever you +prefer. For those who remember, this was one of the main questions +with KDE-1.x ("How to get rid of session managment?"). With KDE-2.x, +most users will probably prepare a session once, store it with the +checkbox enabled and keep the checkbox disabled in the future. This +way you get a proper and clean 'homesession' each time. + + +Troubleshooting +--------------- + +If you experience trouble like 'logout does not work anymore' or 'I +cannot start new applications', as a result of a previous crash, +ensure that ksmserver is indeed not running anymore and remove the +file ~/.kde/socket-$HOSTNAME/KSMserver-$DISPLAY. Shouldn't be necessry, +but one never knows. + diff --git a/ksmserver/client.cpp b/ksmserver/client.cpp new file mode 100644 index 000000000..784de496c --- /dev/null +++ b/ksmserver/client.cpp @@ -0,0 +1,190 @@ +/***************************************************************** +ksmserver - the KDE session management server + +Copyright (C) 2000 Matthias Ettrich <ettrich@kde.org> +Copyright (C) 2005 Lubos Lunak <l.lunak@kde.org> + +relatively small extensions by Oswald Buddenhagen <ob6@inf.tu-dresden.de> + +some code taken from the dcopserver (part of the KDE libraries), which is +Copyright (c) 1999 Matthias Ettrich <ettrich@kde.org> +Copyright (c) 1999 Preston Brown <pbrown@kde.org> + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
