Le Comit\u00e9 FESCo (Fedora Engineering Steering Committee), responsable de la partie technique du d\u00e9veloppement de la distribution Fedora, a approuv\u00e9<\/a><\/noindex> proposition de mise en \u0153uvre du projet<\/a><\/noindex> ELN<\/a><\/noindex> (Enterprise Linux Next), visant \u00e0 fournir un environnement bas\u00e9 sur le d\u00e9p\u00f4t Fedora Rawhide, qui peut \u00eatre utilis\u00e9 pour tester les fonctionnalit\u00e9s des futures versions de la distribution RHEL (Red Hat Enterprise Linux). Un nouveau buildroot sera pr\u00e9par\u00e9 pour l'ELN et le processus de construction<\/a><\/noindex> pour \u00e9muler la formation de Red Hat Enterprise Linux \u00e0 partir de paquets avec des codes sources du d\u00e9p\u00f4t Fedora. Le projet est pr\u00e9vu pour \u00eatre mis en \u0153uvre dans le cadre du cycle de d\u00e9veloppement de Fedora 33. <\/p>\n

ELN<\/a><\/noindex> fournira une infrastructure permettant de compiler des paquets Fedora en utilisant des m\u00e9thodes compatibles avec CentOS et RHEL, et donnera aux mainteneurs de paquets Fedora \u00e0 un stade pr\u00e9coce la possibilit\u00e9 de d\u00e9tecter les changements qui pourraient potentiellement affecter le d\u00e9veloppement de RHEL. ELN permettra \u00e9galement de v\u00e9rifier les modifications attendues des blocs conditionnels dans les fichiers spec, c'est-\u00e0-dire de compiler le paquet avec la condition variable \"%{rhel}%\" d\u00e9finie \u00e0 \"9\" (la variable \"%{fedora}%\" dans ELN renverra \"false\"), simulant ainsi la compilation pour la future branche RHEL. <\/p>\n

L'objectif final est de reconstruire le d\u00e9p\u00f4t Fedora Rawhide comme s'il s'agissait de RHEL. Dans l'ELN, seules une petite partie de la collection de paquets Fedora, demand\u00e9e dans CentOS Stream et RHEL, sera reconstruite. Les reconstructions r\u00e9ussies de l'ELN seront synchronis\u00e9es avec les constructions internes de RHEL, en ajoutant des modifications suppl\u00e9mentaires dans les paquets qui ne sont pas autoris\u00e9es dans Fedora (par exemple, l'ajout de marques commerciales). Dans ce processus, les d\u00e9veloppeurs s'efforceront de minimiser les diff\u00e9rences entre l'ELN et RHEL Next, en les s\u00e9parant au niveau des blocs conditionnels dans les fichiers spec.<\/p>\n

Une autre application importante de l'ELN sera la possibilit\u00e9 d'exp\u00e9rimenter la r\u00e9alisation de nouvelles id\u00e9es sans affecter les versions principales de Fedora. En particulier, l'ELN sera utile pour cr\u00e9er des versions de Fedora qui refl\u00e8tent la suppression<\/a><\/noindex> le support du mat\u00e9riel ancien et l'activation par d\u00e9faut d'extensions CPU suppl\u00e9mentaires. Par exemple, il sera possible de cr\u00e9er simultan\u00e9ment une version de Fedora, en d\u00e9finissant dans les exigences CPU le support obligatoire des instructions AVX2, puis de tester l'impact sur la performance de l'utilisation d'AVX2 dans les paquets et de d\u00e9cider de l'impl\u00e9mentation de cette modification dans la distribution principale de Fedora.
\nCes tests sont pertinents pour v\u00e9rifier les paquets Fedora dans le cadre des changements des exigences pour les architectures mat\u00e9rielles, pr\u00e9vus dans la prochaine branche significative de RHEL, sans bloquer le processus normal de compilation des paquets et de pr\u00e9paration des versions de Fedora.<\/p>\n
