Benjamin Berg (Benjamin Berg<\/a><\/noindex>), un des ing\u00e9nieurs de Red Hat, travaillant sur le d\u00e9veloppement de GNOME, a r\u00e9sum\u00e9<\/a><\/noindex> les r\u00e9sultats du travail de traduction de GNOME pour la gestion des sessions exclusivement via systemd, sans utiliser le processus gnome-session. <\/p>\n

Pour g\u00e9rer l'acc\u00e8s \u00e0 GNOME, on utilise d\u00e9j\u00e0 depuis longtemps systemd-logind<\/a><\/noindex>, qui suit les \u00e9tats des sessions associ\u00e9es \u00e0 l'utilisateur, g\u00e8re les identifiants de session, s'occupe du basculement entre les sessions actives, coordonne les environnements multi-utilisateurs (Multi-seat), d\u00e9finit des politiques d'acc\u00e8s aux appareils, fournit des outils pour l'arr\u00eat et la mise en veille, etc. <\/p>\n

Ainsi, une partie des fonctionnalit\u00e9s li\u00e9es aux sessions \u00e9tait toujours assur\u00e9e par le processus gnome-session, qui g\u00e9rait via D-Bus, le lancement du gestionnaire d'affichage et des composants GNOME, ainsi que l'organisation du d\u00e9marrage automatique des applications sp\u00e9cifi\u00e9es par l'utilisateur. Dans le cadre du d\u00e9veloppement de GNOME 3.34, les capacit\u00e9s sp\u00e9cifiques \u00e0 gnome-session ont \u00e9t\u00e9 con\u00e7ues sous forme de fichiers unitaires pour systemd, ex\u00e9cut\u00e9s en mode \u00ab systemd --user \u00bb, c'est-\u00e0-dire li\u00e9s \u00e0 l'environnement d'un utilisateur sp\u00e9cifique, et non \u00e0 l'ensemble du syst\u00e8me. Les modifications ont d\u00e9j\u00e0 \u00e9t\u00e9 appliqu\u00e9es dans la distribution Fedora 31, dont la sortie est attendue \u00e0 la fin octobre.<\/p>\n

L'utilisation de systemd a permis d'organiser le lancement des gestionnaires \u00e0 la demande ou lors de certains \u00e9v\u00e9nements, ainsi qu'une r\u00e9action plus sophistiqu\u00e9e aux terminaisons pr\u00e9matur\u00e9es des processus en raison de pannes et un traitement \u00e9largi des d\u00e9pendances lors du lancement des composants GNOME. En cons\u00e9quence, il est possible de r\u00e9duire le nombre de processus toujours en cours d'ex\u00e9cution et de diminuer la consommation de m\u00e9moire. Par exemple, XWayland peut d\u00e9sormais \u00eatre lanc\u00e9 uniquement lorsqu'une application utilisant le protocole X11 est ex\u00e9cut\u00e9e, et les composants sp\u00e9cifiques \u00e0 un mat\u00e9riel donn\u00e9, uniquement en pr\u00e9sence de ce mat\u00e9riel (par exemple, les gestionnaires pour les cartes \u00e0 puce seront lanc\u00e9s lors de l'insertion de la carte et arr\u00eat\u00e9s lors de son retrait). <\/p>\n

L'utilisateur dispose d'outils de gestion du d\u00e9marrage des services plus flexibles, par exemple, il suffit d'ex\u00e9cuter \u00ab systemctl --user stop gsd-media-keys.target \u00bb pour d\u00e9sactiver le gestionnaire des touches multim\u00e9dias. En cas de probl\u00e8me, les journaux li\u00e9s \u00e0 chaque gestionnaire peuvent \u00eatre consult\u00e9s avec la commande journalctl (par exemple, \u00ab journalctl --user -u gsd-media-keys.service \u00bb), apr\u00e8s avoir activ\u00e9 le logging de d\u00e9bogage dans le service (\u00ab Environment=G_MESSAGES_DEBUG=all \u00bb). Il est \u00e9galement possible de lancer dans des environnements sandbox isol\u00e9s tous les composants GNOME auxquels des exigences de s\u00e9curit\u00e9 \u00e9lev\u00e9es sont appliqu\u00e9es. <\/p>\n

Pour faciliter la transition, le support de l'ancienne m\u00e9thode de lancement des processus pr\u00e9vu<\/a><\/noindex> \u00e0 conserver pendant plusieurs cycles de d\u00e9veloppement de GNOME. Ensuite, les d\u00e9veloppeurs proc\u00e9deront \u00e0 une r\u00e9vision de l'\u00e9tat de gnome-session et tr\u00e8s probablement (marqu\u00e9 comme \u00ab probable \u00bb) supprimeront les moyens de lancer des processus et d'accompagner l'API D-Bus. Ensuite, l'utilisation de \u00ab systemd --user \u00bb sera consid\u00e9r\u00e9e comme une fonctionnalit\u00e9 obligatoire, ce qui pourrait entra\u00eener des difficult\u00e9s pour les syst\u00e8mes sans systemd et n\u00e9cessiter des solutions alternatives, comme cela avait \u00e9t\u00e9 le cas \u00e0 l'\u00e9poque. systemd-logind<\/a><\/noindex>. Cependant, lors de sa pr\u00e9sentation \u00e0 la conf\u00e9rence GUADEC 2019, Benjamin Berg a mentionn\u00e9 l'intention de conserver le soutien de l'ancienne m\u00e9thode de lancement pour les syst\u00e8mes sans systemd, mais cette information contredit les plans pour page du projet<\/a><\/noindex>. <\/p>\n
