Objavljen je prvi testni izvod web preglednika FixBrowser, zasnovan na niskoj potro\u0161nji resursa i osiguranju privatnosti. Preglednik se razvija od nule i principijelno ne podr\u017eava izvr\u0161avanje JavaScripta, ali omogu\u0107ava rad s web stranicama vezanim za JavaScript. Kod je napisan na jezicima C i FixScript, i distribuira se pod ZLIB licencom. Gotove verzije su formirane za Linux (GTK2) i Windows. Planira se izrada verzija za Haiku i macOS 10.6+, kao i formiranje verzija za Linux koje koriste GTK3\/4. <\/p>\n

Za rad s web stranicama vezanim za JavaScript, FixBrowser koristi posrednika FixProxy, koji u stvarnom vremenu pretvara takve stranice u oblik koji se mo\u017ee koristiti bez JavaScripta. Zamjena se vr\u0161i prema standardnim predlo\u0161cima, kao i uz pomo\u0107 fix-obradnika, koji uzimaju u obzir specifi\u010dnosti odre\u0111enih stranica (uklju\u010deni su fix-obradnici za vi\u0161e od 1200 stranica). FixProxy se razvija kao zaseban proxy proces, koji nije vezan uz FixBrowser i mo\u017ee se koristiti s drugim preglednicima. <\/p>\n

Ugotovljeno je, da so za prikaz ve\u010dine spletnih strani brez JavaScript potrebne le majhne spremembe. Poleg tega \u0161tevilne spletne strani uporabljajo enotne tehnologije za dinami\u010dno generiranje vsebine, kar omogo\u010da uporabo standardnih popravljalcev za njihovo upodabljanje. Na primer, lahko se uporabijo univerzalni popravljalci za spletne strani, ki temeljijo na WordPress motorju in forumih na platformi Disqus. Mo\u017eno je ustvariti tudi popravljalce za spletne strani, ki dinami\u010dno upodabljajo vsebino \u2014 na primer, za prikaz seznama komentarjev, ki se prvotno nalagajo dinami\u010dno s pomo\u010djo JavaScript, popravljalec neposredno nalaga podatke v formatu JSON in samostojno oblikuje HTML na njihovi podlagi. <\/p>\n

Za obradu CAPTCHA-e i JavaScript komponenti, poput CloudFlare provjera, bez kojih nije mogu\u0107e pristupiti odre\u0111enim stranicama, planira se izraditi posrednik temeljen na CEF (Chromium Embedded Framework), koji \u0107e mo\u0107i selektivno izvr\u0161avati samo neophodni JavaScript kod. Posrednik za JavaScript \u0107e biti implementiran kao zasebna usluga (mo\u017ee se pokrenuti na vlastitom sustavu, ali se mo\u017ee iskoristiti i javni oblaku usluga). <\/p>\n

Za blokado sledenja aktivnosti uporabnika je nalaganje virov iz zunanjih stre\u017enikov prepovedano, za omogo\u010danje nalaganja slik preko omre\u017eij za dostavo vsebin pa se uporabljajo bele liste. Podpora za HTTPS je na voljo. Mo\u017eno je povezovanje raz\u0161iritev, napisanih v jeziku FixScript. <\/p>\n

Projekt razvija Martin Dvor\u017eak iz \u010ce\u0161ke, ki je neko\u010d ustvaril programski jezik FixScript. Ve\u010dina kode FixBrowser je napisana v jeziku FixScript, razen kriti\u010dnih operacij za zmogljivost in osnovne zasnove. Koda v FixScriptu se vgradi v C-kodo, pri \u010demer se uporablja prevajalnik, dobavljen v eni datoteki, ki vsebuje pribli\u017eno 27 tiso\u010d vrstic C-kode (800 Kb). Jezik spominja na C, vendar uporablja dinami\u010dno tipizacijo, zbiralnik smeti in JIT-prevajanje. FixBrowser zagotavlja varno delo s pomnilnikom in niti, prav tako pa ima vgrajeno za\u0161\u010dito pred prelivanji celih \u0161tevil. <\/p>\n

Izvedbo spletnega brskalnika je uspelo znatno poenostaviti, saj FixBrowser izvaja samo primarno risanje in ne podpira dinami\u010dnega posodabljanja vsebine. Ko je stran prikazana, se ve\u010d ne spreminja, zato lahko brez abstrakcij, kot je DOM (Model objekta dokumenta), obvladamo naloge. Trenutno je delo osredoto\u010deno na ustvarjanje HTML-parserja, ki podpira specifikacije HTML5. Predlagana v prvi testni izdaji \u0161e pokriva le 30% testov HTML5. Osnovna podpora za CSS je realizirana.
