Proiectul rars este un instrument liber pentru formatul RAR, dezvoltat \u00een limbajul Rust, care suport\u0103 at\u00e2t dezarhivarea, c\u00e2t \u0219i crearea arhivelor RAR. Instrumentul sus\u021bine at\u00e2t formatele timpurii RAR 1.3\/1.4 cu semn\u0103tura \u00abRE~^\u00bb, c\u00e2t \u0219i cea mai recent\u0103 versiune RAR 7. Sunt disponibile opera\u021biuni avansate, cum ar fi \u00eemp\u0103r\u021birea \u00een volume, protec\u021bia prin parol\u0103, criptarea antetelor, ata\u0219area de comentarii, filtre RARVM, indici pentru deschiderea rapid\u0103 \u0219i mecanisme de recuperare a datelor deteriorate. Codul este distribuit sub licen\u021bele MIT \u0219i Apache-2.0. Pe baza bibliotecii PyO3, au fost preg\u0103tite leg\u0103turi pentru limbajul Python care implementeaz\u0103 API-uri de tip rarfile pentru vizualizarea, testarea \u0219i extragerea arhivelor, precum \u0219i API-uri de tip RarBuilder pentru crearea sau recompunerea arhivelor.<\/p>\n

Particularitatea proiectului este c\u0103 acesta realizeaz\u0103 lucrul cu formatul RAR f\u0103r\u0103 a utiliza codul utilitarului unrar, distribuit sub o licen\u021b\u0103 neagr\u0103, care interzice utilizarea codului unrar pentru a recrea algoritmul de compresie RAR sau a dezvolta un arhivator compatibil RAR. Din cauza acestei restric\u021bii, majoritatea arhivatoarelor libere s-au limitat doar la func\u021bionalit\u0103\u021bile de dezarhivare a fi\u0219ierelor RAR, iar pentru crearea arhivelor RAR a fost necesar s\u0103 se foloseasc\u0103 instrumente proprietare de la RARLAB.<\/p>\n

A fost creat un repository separat rar-research \u00een care sunt publicate specifica\u021biile pentru formatele RAR 1.3\/1.4, RAR 1.5-4.x \u0219i RAR 5.0\/7.0, precum \u0219i note despre algoritmii folosi\u021bi, filtre, metode de verificare \u0219i recuperare a integrit\u0103\u021bii, criptare, \u00eemp\u0103r\u021bire \u00een volume \u0219i mecanisme de protec\u021bie. Deoarece la momentul cre\u0103rii proiectului rars nu exista o specifica\u021bie oficial\u0103 complet\u0103, documenta\u021bia a fost recreat\u0103 pe baza codului dezarhivatoarelor, implement\u0103rilor vechi, arhivelor de testare \u0219i analizei versiunilor binare RAR pentru DOS \u0219i Windows.<\/p>\n

Implementarea a fost realizat\u0103 cu ajutorul instrumentelor AI OpenAI Codex 5.5 \u0219i Claude Opus 4.7, \u00een timpul liber, \u00eentr-o perioad\u0103 de aproximativ cinci s\u0103pt\u0103m\u00e2ni. \u00cen prima etap\u0103, modelele au fost utilizate pentru a sistematiza informa\u021biile despre format \u0219i pentru a completa lacunele din descriere, dup\u0103 care, conform specifica\u021biei restaurate, a fost generat cod \u00een limbajul Rust. Pentru a clarifica specifica\u021bia \u0219i a rafina implementarea, s-au folosit teste pe arhive reale \u0219i compara\u021bii cu implement\u0103rile de referin\u021b\u0103.<\/p>\n

Se observ\u0103 c\u0103 instrumentele AI au gestionat bine transferul descrierii formale \u00een cod \u0219i realizarea de rutin\u0103 a unui volum mare de func\u021bionalitate, dar nu au reu\u0219it s\u0103 asigure un control arhitectural. F\u0103r\u0103 o supraveghere strict\u0103, modelele AI au fost predispuse s\u0103 evite teste, s\u0103 complice codul \u0219i s\u0103 ignore probleme evidente care afectau usabilitatea. Conform evalu\u0103rii autorului, \u00een cadrul unui proiect de aceast\u0103 amploare, testele, documenta\u021bia \u0219i comentariile au devenit nu doar unelte de verificare, ci \u0219i o modalitate de a direc\u021biona generarea de cod \u00een direc\u021bia dorit\u0103.<\/p>\n

Dezvoltarea a fost accelerat\u0103 dup\u0103 apari\u021bia modului \u00ab\/goal\u00bb \u00een OpenAI Codex, care permite agentului AI s\u0103 lucreze perioade \u00eendelungate asupra unei sarcini, comprim\u00e2nd contextul \u0219i continu\u00e2nd execu\u021bia dup\u0103 ce acesta s-a umplut. \u00cen aceast\u0103 modul, Codex a func\u021bionat de c\u00e2teva ori mai mult de 6 ore \u0219i o dat\u0103 aproximativ 16 ore, realiz\u00e2nd o parte semnificativ\u0103 din func\u021bionalitatea r\u0103mas\u0103, cum ar fi recuperarea datelor, criptarea \u0219i arhivele multivolum. Lu\u00e2nd \u00een considerare subven\u021bia semnificativ\u0103 pentru token-uri, au fost cheltuite 40 de lire sterline.<\/p>\n

\u00cen ceea ce prive\u0219te nivelul de compresie, rars este \u00een medie cu 5-10% mai lent dec\u00e2t WinRAR. \u00cen ceea ce prive\u0219te viteza de compresie \u0219i dezarhivare, rars este semnificativ mai lent dec\u00e2t WinRAR din cauza lipsa optimiz\u0103rilor complete. Totu\u0219i, \u00een proiect exist\u0103 deja modul \u00ab\u2014features fast\u00bb, care aplic\u0103 optimiz\u0103ri bazate pe instruc\u021biuni SIMD pentru accelerarea compresiei \u0219i dezarhiv\u0103rii, dar legat de API-ul experimental std::simd, disponibil doar \u00een versiunile de testare ale instrumentarului Rust. A fost implementat, de asemenea, modul \u00ab\u2014features parallel\u00bb, care utilizeaz\u0103 biblioteca Rayon pentru paralelizarea compresiei fi\u0219ierelor individuale.<\/p>\n

Evgheni Ro\u0219al, creatorul RAR, a comentat utilizarea ingineriei inverse a vechilor fi\u0219iere binare RAR \u00een dezvoltarea rars, ceea ce este interzis de acordul de licen\u021b\u0103. Potrivit lui Evgheni, el nu s-a decis \u00eenc\u0103 ce s\u0103 fac\u0103 \u00een leg\u0103tur\u0103 cu aceasta \u0219i inten\u021bioneaz\u0103 s\u0103 a\u0219tepte opinia companiei win.rar GmbH.
