Benjamin Berg (Benjamin Berg<\/a><\/noindex>), unul dintre inginerii Red Hat, care se ocup\u0103 cu dezvoltarea GNOME, a sintetizat<\/a><\/noindex> rezultatele muncii asupra port\u0103rii GNOME pentru gestionarea sesiunilor exclusiv prin intermediul systemd, f\u0103r\u0103 utilizarea procesului gnome-session. <\/p>\n

Pentru gestionarea autentific\u0103rii \u00een GNOME, deja de ceva timp se utilizeaz\u0103 systemd-logind<\/a><\/noindex>, care urm\u0103re\u0219te st\u0103rile sesiunilor legate de utilizator, administreaz\u0103 identificatorii sesiunilor, este responsabil de comutarea \u00eentre sesiunile active, coordoneaz\u0103 mediile multi-utilizator (Multi-seat), configureaz\u0103 politicile de acces la dispozitive, ofer\u0103 instrumente pentru oprirea \u0219i intrarea \u00een modul de repaus etc. <\/p>\n

\u00centre timp, o parte a func\u021bionalit\u0103\u021bii legate de sesiuni a r\u0103mas \u00een sarcina procesului gnome-session, care se ocupa cu gestionarea prin D-Bus, lansarea managerului de afi\u0219are \u0219i componentelor GNOME, organizarea autolans\u0103rii aplica\u021biilor specificate de utilizator. \u00cen procesul de dezvoltare a GNOME 3.34, func\u021bionalit\u0103\u021bile specifice pentru gnome-session au fost formulate sub form\u0103 de fi\u0219iere unit\u0103\u021bi pentru systemd, care sunt executate \u00een modul \u201esystemd --user\u201d, adic\u0103 \u00een leg\u0103tur\u0103 cu mediul unui utilizator specific \u0219i nu al \u00eentregului sistem. Modific\u0103rile au fost deja aplicate \u00een distribu\u021bia Fedora 31, a c\u0103rei lansare este a\u0219teptat\u0103 la sf\u00e2r\u0219itul lunii octombrie.<\/p>\n

Utilizarea systemd a permis organizarea lans\u0103rii handler-urilor la cerere sau la apari\u021bia anumitor evenimente, precum \u0219i reac\u021bii mai sofisticate la \u00eencheierea prematur\u0103 a proceselor din cauza erorilor \u0219i gestionarea extins\u0103 a dependen\u021belor la lansarea componentelor GNOME. Ca urmare, se poate reduce num\u0103rul de procese care ruleaz\u0103 constant \u0219i se poate diminua consumul de memorie. De exemplu, XWayland poate fi lansat acum doar \u00een momentul \u00een care se \u00eencearc\u0103 utilizarea unei aplica\u021bii pe baza protocolului X11, iar componentele specifice anumitor echipamente, doar \u00een prezen\u021ba acestora (de exemplu, handler-urile pentru cardurile inteligente vor fi activate la inser\u021bia cardului \u0219i se vor opri la extragerea acestuia). <\/p>\n

Utilizatorul a primit instrumente de gestionare a lans\u0103rii serviciilor mai flexibile, de exemplu, pentru a dezactiva procesorul tastele multimedia, este suficient s\u0103 executa\u021bi \u201esystemctl --user stop gsd-media-keys.target\u201d. \u00cen caz de probleme, log-urile legate de fiecare procesor pot fi vizualizate cu comanda journalctl (de exemplu, \u201ejournalctl --user -u gsd-media-keys.service\u201d), activ\u00e2nd anterior \u00een serviciu \u00eenregistrarea log-ului de depanare (\u201eEnvironment=G_MESSAGES_DEBUG=all\u201d). De asemenea, a ap\u0103rut posibilitatea de a lansa \u00een medii sandbox izolate toate componentele GNOME, la care se cer cerin\u021be sporite de securitate. <\/p>\n

Pentru a netezi tranzi\u021bia, suportul vechii metode de lansare a proceselor se preconizeaz\u0103<\/a><\/noindex> s\u0103 fie p\u0103strate pe parcursul mai multor cicluri de dezvoltare GNOME. Apoi, dezvoltatorii vor efectua o revizuire a st\u0103rii gnome-session \u0219i, probabil (marcat ca \u201eprobabil\u201d) vor elimina metodele de lansare a proceselor \u0219i de \u00eentre\u021binere a API-ului D-Bus. Apoi, aplicarea \u201esystemd --user\u201d va fi considerat\u0103 o func\u021bie obligatorie, ceea ce poate crea dificult\u0103\u021bi pentru sistemele f\u0103r\u0103 systemd \u0219i va necesita preg\u0103tirea unei solu\u021bii alternative, a\u0219a cum s-a \u00eent\u00e2mplat odat\u0103. systemd-logind<\/a><\/noindex>. Cu toate acestea, \u00een discursul s\u0103u de la conferin\u021ba GUADEC 2019, Benjamin Berg a men\u021bionat inten\u021bia de a men\u021bine suportul pentru vechea metod\u0103 de lansare pentru sistemele f\u0103r\u0103 systemd, dar aceast\u0103 informa\u021bie este \u00een contradic\u021bie cu planurile pentru pagina proiectului<\/a><\/noindex>. <\/p>\n
