Benjamin Berg (Benjamin Berg<\/a><\/noindex>), en av ingeni\u00f8rene hos Red Hat som jobber med utviklingen av GNOME, oppsummerte<\/a><\/noindex> resultatene av arbeidet med \u00e5 oversette GNOME til \u00e5 h\u00e5ndtere sesjoner utelukkende ved hjelp av systemd, uten bruk av gnome-session-prosessen. <\/p>\n

For \u00e5 h\u00e5ndtere innlogging i GNOME har man lenge brukt systemd-logind<\/a><\/noindex>, som sporer sesjonsstatus knyttet til brukeren, administrerer sesjons-ID-er, h\u00e5ndterer bytting mellom aktive sesjoner, koordinerer flerbruksomgivelser (Multi-seat), konfigurerer tilgangspolicyer for enheter, og gir midler for \u00e5 avslutte eller sette systemet i hvilemodus, etc. <\/p>\n

Samtidig forble en del av funksjonaliteten knyttet til sesjoner p\u00e5 skuldrene til prosessen gnome-session, som h\u00e5ndterte styring via D-Bus, oppstart av display-manager og komponenter i GNOME, samt organisering av autostart for brukerdefinerte applikasjoner. I l\u00f8pet av utviklingen av GNOME 3.34 har spesifikke funksjoner for gnome-session blitt utviklet i form av enhet-filer for systemd, som kj\u00f8res i «systemd —user»-modus, det vil si i tilknytning til et spesifikt brukerens milj\u00f8, og ikke hele systemet. Endringer er allerede implementert i distribusjonen Fedora 31, hvis utgivelse forventes mot slutten av oktober.<\/p>\n

Bruken av systemd har gjort det mulig \u00e5 organisere oppstarten av h\u00e5ndterere p\u00e5 foresp\u00f8rsel eller ved passende hendelser, samt mer sofistikert reagere p\u00e5 uventet avslutning av prosesser p\u00e5 grunn av feil, og bedre h\u00e5ndtere avhengigheter ved oppstart av GNOME-komponenter. Som en konsekvens er det mulig \u00e5 redusere antallet prosesser som kj\u00f8rer konstant og senke minneforbruket. For eksempel kan XWayland n\u00e5 bare startes ved fors\u00f8k p\u00e5 \u00e5 kj\u00f8re en applikasjon basert p\u00e5 X11-protokollen, mens komponenter spesifik for bestemt maskinvare kun kj\u00f8rer n\u00e5r slik maskinvare er til stede (for eksempel vil h\u00e5ndtere for smartkort bli startet ved innsetting av kortet og avslutte ved fjerning). <\/p>\n

Brukeren har f\u00e5tt mer fleksible verkt\u00f8y for \u00e5 administrere oppstart av tjenester, for eksempel, for \u00e5 deaktivere h\u00e5ndterer av medierelaterte taster, er det tilstrekkelig \u00e5 utf\u00f8re «systemctl —user stop gsd-media-keys.target». I tilfelle problemer knyttet til hver h\u00e5ndterer kan logger vises ved hjelp av kommandoen journalctl (for eksempel, «journalctl —user -u gsd-media-keys.service»), etter \u00e5 ha aktivert feils\u00f8kingsloggf\u00f8ring i tjenesten («Environment=G_MESSAGES_DEBUG=all»). Det er ogs\u00e5 blitt mulig \u00e5 kj\u00f8re alle komponenter i GNOME i isolerte sandbox-milj\u00f8er, som stiller strengere krav til sikkerhet. <\/p>\n

For \u00e5 myke opp overgangen, st\u00f8tte den gamle metoden for \u00e5 starte prosesser bli planlagt<\/a><\/noindex> bevare i l\u00f8pet av flere utviklingssykluser av GNOME. Deretter vil utviklerne gjennomf\u00f8re en vurdering av tilstanden til gnome-session, og mest sannsynlig (merket som «likely») fjerne oppstartsmekanismer og vedlikehold av D-Bus API fra den. Deretter vil bruken av «systemd —user» bli overf\u00f8rt til en obligatorisk funksjon, noe som kan skape utfordringer for systemer uten systemd og kreve forberedelse av alternative l\u00f8sninger, slik det en gang var med. systemd-logind<\/a><\/noindex>. Likevel nevnte Benjamin Berg i sitt foredrag p\u00e5 GUADEC 2019 at han hadde til hensikt \u00e5 opprettholde st\u00f8tte for den gamle oppstartmetoden for systemer uten systemd, men denne informasjonen er i strid med planene for prosjektets side<\/a><\/noindex>. <\/p>\n
