Daniel Mach da Red Hat anunciou<\/a><\/noindex> anunciou o in\u00edcio do desenvolvimento do gerenciador de pacotes DNF 5, que transferir\u00e1 a l\u00f3gica implementada em Python do DNF para a biblioteca libdnf, escrita em C++. Os testes do DNF 5 est\u00e3o programados para come\u00e7ar em junho durante o desenvolvimento do Fedora 33, ap\u00f3s o qual ser\u00e1 adicionado ao reposit\u00f3rio Rawhide em outubro de 2020 e substituir\u00e1 o DNF 4 em fevereiro de 2021. O suporte para a vers\u00e3o DNF 4 continuar\u00e1, uma vez que \u00e9 utilizado no Red Hat Enterprise Linux 8.<\/p>\n

Observa-se que o projeto atingiu um estado em que \u00e9 quase imposs\u00edvel continuar o desenvolvimento do c\u00f3digo sem comprometer a compatibilidade em n\u00edvel de API\/ABI. Isso se deve principalmente a perda<\/a><\/noindex> a relev\u00e2ncia do PackageKit e a impossibilidade de desenvolvimento do libdnf sem modificar a API \u00ablibhif\u00bb. Apesar da inten\u00e7\u00e3o de alterar a API, a preserva\u00e7\u00e3o da compatibilidade retroativa no n\u00edvel da interface de linha de comando e da API \u00e9 mencionada como uma das principais prioridades.<\/p>\n

O suporte para a API Python no DNF ser\u00e1 mantido, mas a l\u00f3gica de neg\u00f3cios escrita em Python ser\u00e1 transferida para a biblioteca libdnf (C++), o que garantir\u00e1 a identidade do funcionamento do gerenciador de pacotes na distribui\u00e7\u00e3o. O desenvolvimento se concentrar\u00e1 na API C++, e a API Python ser\u00e1 gerada automaticamente como uma camada sobre essa base.
\nDa mesma forma, ser\u00e3o formadas as liga\u00e7\u00f5es para Go, Perl e
\nRuby. Ap\u00f3s a estabiliza\u00e7\u00e3o da API C++, uma API C ser\u00e1 preparada com base nessa vers\u00e3o, para a qual o rpm-ostree ser\u00e1 transferido. Hawkey<\/a><\/noindex> A API Python ser\u00e1 removida e substitu\u00edda por libdnf<\/a><\/noindex> API Python.<\/p>\n

A funcionalidade principal do DNF ser\u00e1 mantida. Com um grande conjunto de testes (cerca de 1400 testes), espera-se que a reformula\u00e7\u00e3o da API n\u00e3o afete a interface de linha de comando para os usu\u00e1rios finais. A an\u00e1lise de argumentos e a sa\u00edda podem mudar um pouco, mas essas altera\u00e7\u00f5es ser\u00e3o bem documentadas. Em uma vers\u00e3o reduzida, microdnf<\/a><\/noindex>, que ser\u00e1 aplicada em cont\u00eaineres, planeja-se implementar um subconjunto das funcionalidades do DNF, n\u00e3o se considerando alcan\u00e7ar paridade completa em funcionalidades.<\/p>\n

Em vez de PackageKit<\/a><\/noindex> um novo servi\u00e7o DBus ser\u00e1 criado, oferecendo uma interface para gerenciar pacotes e atualiza\u00e7\u00f5es para aplicativos gr\u00e1ficos. Este servi\u00e7o est\u00e1 previsto para ser desenvolvido do zero, portanto, sua cria\u00e7\u00e3o pode exigir muito tempo. O PackageKit n\u00e3o tem evolu\u00eddo ultimamente e est\u00e1 em modo de manuten\u00e7\u00e3o desde 2014 devido \u00e0 perda de relev\u00e2ncia. Com a promo\u00e7\u00e3o dos sistemas Snaps e Flatpak, as distribui\u00e7\u00f5es est\u00e3o perdendo interesse no PackageKit, por exemplo, ele j\u00e1 n\u00e3o \u00e9 inclu\u00eddo nas compila\u00e7\u00f5es. Fedora SilverBlue<\/a><\/noindex>. O n\u00edvel de abstra\u00e7\u00e3o para gerenciamento de pacotes \u00e9 em grande parte garantido pelos centros de gerenciamento de aplicativos padr\u00e3o do GNOME e KDE, que permitem a instala\u00e7\u00e3o de pacotes flatpak no n\u00edvel de usu\u00e1rios individuais. Uma API sist\u00eamica unificada para obter uma lista de pacotes instalados se torna menos \u00fatil do que antes.<\/p>\n
