Les sp\u00e9cialistes de Mozilla ont pr\u00e9sent\u00e9 le projet WASI (WebAssembly System Interface), qui pr\u00e9voit le d\u00e9veloppement d'API pour cr\u00e9er des applications classiques ex\u00e9cut\u00e9es en dehors des navigateurs. Cela implique initialement la compatibilit\u00e9 multiplateforme et un haut niveau de s\u00e9curit\u00e9 pour ces applications.<\/p>\n

Comme indiqu\u00e9, elles s'ex\u00e9cutent dans un \u00ab bac \u00e0 sable \u00bb sp\u00e9cial et ont acc\u00e8s aux fichiers, au syst\u00e8me de fichiers, aux sockets r\u00e9seau, aux minuteurs, etc. Dans ce contexte, le programme ne peut effectuer que des actions clairement autoris\u00e9es.<\/p>\n

\u00c9tant donn\u00e9 que le pseudocode WebAssembly est une variante ind\u00e9pendante de la plate-forme du langage Assembleur, l'utilisation de JIT permettra d'atteindre une haute performance du code, comparable \u00e0 celle des applications natives. Actuellement, une impl\u00e9mentation des API POSIX de base (fichiers, sockets, etc.) est disponible, mais elle ne prend pas encore en charge les verrous et l'E\/S asynchrone. \u00c0 l'avenir, des modules pour la cryptographie, le travail avec la 3D, les capteurs et les multim\u00e9dias sont attendus.<\/p>\n

Il convient \u00e9galement de noter que le projet Fastly a pr\u00e9sent\u00e9 le compilateur Lucet pour les applications WebAssembly. Celui-ci permet d'ex\u00e9cuter en toute s\u00e9curit\u00e9 des programmes tiers sur WebAssembly \u00e0 l'int\u00e9rieur d'autres applications, ce qui est appropri\u00e9 pour les plugins. Le compilateur lui-m\u00eame est \u00e9crit en Rust et prend en charge le code en C, Rust et TypeScript.<\/p>\n

Bien entendu, de nombreuses questions subsistent concernant la s\u00e9curit\u00e9 de cette approche. L'ex\u00e9cution de code dans un \u00ab bac \u00e0 sable \u00bb est en d\u00e9calage \u00e9trange avec l'acc\u00e8s aux fonctionnalit\u00e9s du syst\u00e8me principal, donc cette question n\u00e9cessite encore des \u00e9claircissements. De plus, il n'est pas clair quelles applications doivent fonctionner dans ce mode et comment leur comportement devra \u00eatre surveill\u00e9.<\/p>\n
