Daniel Mach fr\u00e5n Red Hat meddelade<\/a><\/noindex> ang\u00e5ende starten av utvecklingen av paketf\u00f6rvaltaren DNF 5, d\u00e4r logiken fr\u00e5n DNF, implementerad i Python, kommer att flyttas till biblioteket libdnf, skrivet i C++. Testning av DNF 5 planeras att b\u00f6rja i juni under utvecklingen av Fedora 33, och i oktober 2020 kommer den att l\u00e4ggas till i Rawhide-repositoriet, medan den i februari 2021 kommer att ers\u00e4tta DNF 4. Underh\u00e5llet av DNF 4-grenen kommer att forts\u00e4tta, eftersom den anv\u00e4nds i Red Hat Enterprise Linux 8.<\/p>\n

St\u00f6det f\u00f6r Python API i DNF kommer att kvarst\u00e5, men den p\u00e5 Python skrivna aff\u00e4rslogiken kommer att flyttas till biblioteket libdnf (C++), vilket kommer att garantera identisk funktionalitet f\u00f6r paketf\u00f6rvaltaren i distributionen. Utvecklingen kommer att fokuseras p\u00e5 C++ API:t, medan Python API:t kommer att genereras automatiskt i form av en wrapper.
\nP\u00e5 liknande s\u00e4tt kommer bindningar att formas f\u00f6r Go, Perl och
\nRuby. Efter att C++ API:t har stabiliserats kommer \u00e4ven C API:t att f\u00f6rberedas, som rpm-ostree kommer att \u00f6vers\u00e4ttas till. Hawkey<\/a><\/noindex> Python API:t kommer att tas bort och ers\u00e4ttas med libdnf<\/a><\/noindex> Python API.<\/p>\n

Den grundl\u00e4ggande funktionaliteten i DNF kommer att bevaras. Tack vare ett stort testset (ungef\u00e4r 1400 tester) f\u00f6rv\u00e4ntas API-\u00f6versynen inte p\u00e5verka kommandoradsgr\u00e4nssnittet f\u00f6r slutanv\u00e4ndarna. Det kan m\u00f6jligen bli n\u00e5gra \u00e4ndringar i analysen av argument och utdata, men dessa f\u00f6r\u00e4ndringar kommer att dokumenteras noggrant. I den nedskurna versionen microdnf<\/a><\/noindex>, som anv\u00e4nds i containrar, planeras ett delm\u00e4ngd av DNF:s funktioner, och att uppn\u00e5 fullst\u00e4ndig paritet i funktionalitet \u00f6verv\u00e4gs inte.<\/p>\n

Ist\u00e4llet f\u00f6r PackageKit<\/a><\/noindex> en ny DBus-tj\u00e4nst kommer att skapas, som erbjuder ett gr\u00e4nssnitt f\u00f6r hantering av paket och uppdateringar f\u00f6r grafiska applikationer. Denna tj\u00e4nst planeras att utvecklas fr\u00e5n grunden, s\u00e5 dess skapelse kan ta l\u00e5ng tid. PackageKit har under de senaste \u00e5ren inte utvecklats och har varit i underh\u00e5llsl\u00e4ge sedan 2014 p\u00e5 grund av bristande relevans. Med framv\u00e4xten av Snaps- och Flatpak-systemen tappar distributioner intresset f\u00f6r PackageKit, till exempel ing\u00e5r det inte l\u00e4ngre i versionerna. Fedora SilverBlue<\/a><\/noindex>.
