Speciali\u0219tii de la Mozilla au prezentat proiectul WASI (WebAssembly System Interface), care vizeaz\u0103 dezvoltarea unui API pentru crearea de aplica\u021bii obi\u0219nuite care s\u0103 ruleze \u00een afara browserului. De la bun \u00eenceput, discu\u021bia se axeaz\u0103 pe multiplatformitate \u0219i un nivel \u00eenalt de securitate pentru astfel de aplica\u021bii.<\/p>\n

A\u0219a cum se men\u021bioneaz\u0103, acestea sunt rulate \u00eentr-o \u201ecarcas\u0103\u201d special\u0103 \u0219i au acces la fi\u0219iere, sistemul de fi\u0219iere, socket-uri de re\u021bea, temporizatoare \u0219i a\u0219a mai departe. \u00cen acela\u0219i timp, programul poate efectua doar ac\u021biuni explicit permise.<\/p>\n

Av\u00e2nd \u00een vedere c\u0103 pseudocodul WebAssembly este o variant\u0103 independent\u0103 de platform\u0103 a limbajului Assembler, utilizarea JIT va permite ob\u021binerea unei performan\u021be ridicate a codului, la nivelul aplica\u021biilor native. Momentan, este disponibil\u0103 o implementare a API-urilor POSIX de baz\u0103 (fi\u0219iere, socket-uri etc.), dar nu exist\u0103 \u00eenc\u0103 suport pentru blocaje \u0219i I\/O asincron. \u00cen viitor, se a\u0219teapt\u0103 apari\u021bia modulelor pentru criptografie, lucru cu grafic\u0103 3D, senzori \u0219i multimedia.<\/p>\n

De asemenea, trebuie men\u021bionat c\u0103 proiectul Fastly a prezentat compilatorul Lucet pentru aplica\u021biile WebAssembly. Acesta permite executarea \u00een siguran\u021b\u0103 a programelor externe pe WebAssembly \u00een cadrul altor aplica\u021bii, de exemplu, fiind potrivit pentru plugin-uri. Compilatorul \u00een sine este scris \u00een Rust \u0219i suport\u0103 cod \u00een C, Rust \u0219i TypeScript.<\/p>\n

Desigur, r\u0103m\u00e2n \u00eenc\u0103 multe \u00eentreb\u0103ri cu privire la securitatea unei astfel de abord\u0103ri. Execu\u021bia codului \u00een \u201ecarcas\u0103\u201d se \u00eembin\u0103 destul de ciudat cu accesul la func\u021biile sistemului principal, a\u0219a c\u0103 aceast\u0103 problem\u0103 necesit\u0103 \u00eenc\u0103 clarific\u0103ri. \u00cen plus, nu este clar ce aplica\u021bii trebuie s\u0103 func\u021bioneze \u00een acest mod \u0219i cum va trebui s\u0103 monitoriz\u0103m comportamentul lor.<\/p>\n
