Gli specialisti di Mozilla hanno presentato il progetto WASI (WebAssembly System Interface), che prevede lo sviluppo di API per creare applicazioni standard eseguite al di fuori del browser. Si parla inizialmente di cross-platform e di un alto livello di sicurezza per tali applicazioni.<\/p>\n

\"Mozilla<\/p>\n

Come viene osservato, vengono avviati in una speciale \"sandbox\" e hanno accesso a file, file di sistema, socket di rete, timer e cos\u00ec via. In questo modo, il programma pu\u00f2 eseguire solo azioni chiaramente consentite.<\/p>\n

Considerando che il pseudocodice WebAssembly \u00e8 un'alternativa indipendente dalla piattaforma del linguaggio Assembler, l'uso di JIT consentir\u00e0 di ottenere prestazioni elevate del codice, a livello di applicazioni native. Attualmente \u00e8 stata presentata un'implementazione delle API POSIX di base (file, socket, ecc.), ma non supporta ancora i blocchi e l'input\/output asincrono. In futuro si prevede l'arrivo di moduli per la crittografia, la grafica 3D, i sensori e i multimedia.<\/p>\n

Va anche notato che il progetto Fastly ha presentato il compilatore Lucet per applicazioni WebAssembly. Questo consente di eseguire in modo sicuro programmi esterni in WebAssembly all'interno di altre applicazioni, per esempio, \u00e8 adatto per i plugin. Il compilatore stesso \u00e8 scritto in Rust e supporta codice in C, Rust e TypeScript.<\/p>\n

Naturalmente, rimangono ancora molte domande sulla sicurezza di questo approccio. L'esecuzione del codice nella \"sandbox\" si combina in modo piuttosto bizzarro con l'accesso alle funzioni del sistema principale, quindi questa questione necessita ancora di chiarimenti. Inoltre, non \u00e8 chiaro quali programmi debbano funzionare in questo modo e come sar\u00e0 necessario monitorare il loro comportamento.<\/p>\n
