Autor web-okvira napisanog na jeziku Rust actix-web<\/a><\/noindex> uklonio repozitorij<\/a><\/noindex> nakon \u0161to je do\u0161ao pod udar kritike zbog «neispravne upotrebe» jezika Rust. Framework actix-web, paket koji je preuzet vi\u0161e od 800 tisu\u0107a puta, omogu\u0107uje ugradnju http-server i klijentske funkcionalnosti u aplikacije napisane na jeziku Rust, s fokusom na postizanje maksimalne izvedbe tijekom razvoja i prednja\u010di<\/a><\/noindex> u mnogim testovima web-okvira.<\/p>\n

Nekoliko trenutaka prije incidenta, na issues na GitHub-u prijavljeno je otkri\u0107e neodre\u0111enog pona\u0161anja (Undefined Behaviour) u kodu actix-web servera, \u0161to se doga\u0111a u bloku koji se izvr\u0161ava u unsafe<\/a><\/noindex> (omogu\u0107uje izvo\u0111enje nesigurnih radnji s pokaziva\u010dima). Autor actix-web-a nije uklonio blok unsafe, ve\u0107 je prepravio poziv ovog bloka kako bi se neodre\u0111eno pona\u0161anje izbjeglo. Prijedloge za uklanjanje unsafe-a autor je odbio, pozivaju\u0107i se na mogu\u0107i gubitak performansi i isti\u010du\u0107i da ne koristi unsafe bez potrebe te da je siguran u sigurnost blokova koji rade u ovom re\u017eimu.<\/p>\n

\u010clan tima RustSec, koji je otkrio neodre\u0111eno pona\u0161anje, nije se slo\u017eio i pretpostavio da je upotreba mnogih unsafe-blokova u actix-web-u neopravdana. Nakon toga objavio je
\n\u010dlanak<\/a><\/noindex> o neprihvatljivosti upotrebe unsafe, u kojem je, izme\u0111u ostalog, spomenuto da pristup pokaziva\u010dima kori\u0161ten u actix-webu (vi\u0161e promjenjivih pokaziva\u010da na iste podatke) potencijalno mo\u017ee uzrokovati ranjivosti use-after-free i nije u skladu s razvojnim paradigmatom na Rust-u. <\/p>\n

Nakon rasprave<\/a><\/noindex> o \u010dlanku na Redditu<\/a><\/noindex>, na issues na GitHub-u pojavio se<\/a><\/noindex> talas trolova i autor actix-web-a je bio izlo\u017een navali kritike<\/a><\/noindex> i uvreda zbog pogre\u0161ne upotrebe Rust-a. Autor nije izdr\u017eao psiholo\u0161ki pritisak, uklonio je repozitorij<\/a><\/noindex> i napisao<\/a><\/noindex>, da se povukao iz Open Source-a.<\/p>\n
