Ben Cotton, care ocup\u0103 func\u021bia de Fedora Program Manager la Red Hat, a anun\u021bat inten\u021bia de a trece Fedora Linux la managerul de pachete DNF5. \u00cen Fedora Linux 39, se preconizeaz\u0103 \u00eenlocuirea pachetelor dnf, libdnf \u0219i dnf-cutomatic cu instrumentele DNF5 \u0219i noua bibliotec\u0103 libdnf5. Propunerea nu a fost \u00eenc\u0103 examinat\u0103 de comitetul FESCo (Fedora Engineering Steering Committee), responsabil pentru partea tehnic\u0103 a dezvolt\u0103rii distribu\u021biei Fedora. <\/p>\n
DNF a \u00eenlocuit la vremea sa Yum, care a fost scris \u00een \u00eentregime \u00een Python. \u00cen DNF, func\u021biile de baz\u0103, care necesitau performan\u021b\u0103 \u00eenalt\u0103, au fost rescrise \u0219i transferate \u00een biblioteci C separate: hawkey, librepo, libsolv \u0219i libcomps, \u00eens\u0103 structura \u0219i componentele de nivel \u00eenalt au r\u0103mas \u00een Python. Proiectul DNF5 vizeaz\u0103 unificarea bibliotecilor de baz\u0103 existente, rescrierea componentelor de gestionare a pachetelor restante \u00een Python \u00een C++ \u0219i separarea func\u021bionalit\u0103\u021bii de baz\u0103 \u00een biblioteca libdnf5, cre\u00e2nd \u00een jurul acestei biblioteci un wrapper pentru a p\u0103stra API-ul Python. <\/p>\n
Utilizarea limbajului C++ \u00een loc de Python va permite eliminarea unui num\u0103r mare de dependen\u021be, reducerea dimensiunii instrumentelor \u0219i cre\u0219terea performan\u021bei. O performan\u021b\u0103 mai bun\u0103 este atins\u0103 nu doar prin utilizarea compil\u0103rii \u00een cod ma\u0219in\u0103, ci \u0219i printr-o implementare \u00eembun\u0103t\u0103\u021bit\u0103 a tabelei de tranzac\u021bii, optimizarea \u00eenc\u0103rc\u0103rii din repozitorii \u0219i restructurarea bazei de date (separate bazele cu starea sistemului \u0219i istoricul opera\u021biunilor). Instrumentele DNF5 nu mai sunt legate de PackageKit, fiind \u00eenlocuite de un nou proces de fundal DNF Daemon, care \u00eenlocuie\u0219te func\u021bionalitatea PackageKit \u0219i ofer\u0103 o interfa\u021b\u0103 pentru gestionarea pachetelor \u0219i actualiz\u0103rilor \u00een medii grafice. <\/p>\n
Restructurarea va permite, de asemenea, implementarea unor \u00eembun\u0103t\u0103\u021biri care cresc confortul utiliz\u0103rii managerului de pachete. De exemplu, noul DNF ofer\u0103 o indica\u021bie mai clar\u0103 a progresului opera\u021biunilor; a fost ad\u0103ugat\u0103 suportul pentru utilizarea pachetelor RPM locale \u00een tranzac\u021bii; a fost inclus\u0103 posibilitatea de a ar\u0103ta \u00een rapoartele despre tranzac\u021biile efectuate informa\u021biile emise de scripturile \u00eencorporate \u00een pachete (scriplets); a fost propus un sistem mai avansat de autocompletare a introducerii pentru bash. \u0411\u0435\u043d \u041a\u043e\u0442\u0442\u043e\u043d (Ben Cotton), \u0437\u0430\u043d\u0438\u043c\u0430\u044e\u0449\u0438\u0439
