Podjetje Google dela na zagotavljanju popolnih razli\u010dic brskalnika Chrome za operacijski sistem Fuchsia. V Fuchsii je \u017ee na voljo brskalni\u0161ki motor, osnovan na kodi Chromium, za izvajanje lo\u010denih spletnih aplikacij, vendar brskalnik kot lo\u010den, popoln izdelek za Fuchsia do sedaj ni bil na voljo, platforma pa se je predvsem razvijala za IoT in potro\u0161ni\u0161ke naprave, kot je Nest Hub. V zadnjem \u010dasu se je situacija spremenila in za\u010delo se je obvladovanje zmo\u017enosti Fuchsia, usmerjenih v uporabo kot namizna platforma. <\/p>\n

Vklju\u010duje se tudi nabor sprememb, ki omogo\u010dajo prenos polne razli\u010dice Chromov v Fuchsia. Za\u010detno zbirko Chromov za Fuchsia na\u010drtujemo zaklju\u010diti do izdaje Chromov 94, ki je predvidena za 21. september. Delo na prenosu poteka postopoma \u2014 najprej se zagotovi mo\u017enost sestavljanja okraj\u0161ane razli\u010dice, v kateri so nekatere funkcije zamenjane z reprom, ki jih bo med prenosom zamenjala delujo\u010da koda, ki upo\u0161teva specifiko Fuchsia. Na primer, poteka prilagoditev sistemskega pladnja, nalaganja datotek, funkcije Kliknite klic, dela z odstranljivimi mediji, sinhronizacije, uporabni\u0161kih imenikov, PWA-aplikacij, prikaza informacij o spominu in obremenitve CPU ter uvoza nastavitev iz drugih brskalnikov. <\/p>\n

Spomnimo, da se operacijski sistem Fuchsia razvija pod okriljem podjetja Google od leta 2016, ob upo\u0161tevanju pomanjkljivosti na podro\u010dju skalabilnosti in zagotavljanja varnosti, ki so prisotne na platformi Android. Sistem temelji na mikrojedru Zircon, ki izhaja iz projektov LK, raz\u0161irjenega za uporabo na razli\u010dnih razredih naprav, vklju\u010dno s pametnimi telefoni in osebnimi ra\u010dunalniki. Zircon raz\u0161irja LK s podporo procesom in deljenim knji\u017enicam, nivojem uporabnika, sistemom obdelave predmetov in modelom zagotavljanja varnosti, temelje\u010dim na zmogljivosti. Gonilniki se izvajajo kot dinami\u010dne knji\u017enice v uporabni\u0161kem prostoru, ki jih nalaga proces devhost in upravlja upravljalnik naprav (devmg, Device Manager). <\/p>\n

Za Fuchsia je pripravljen lasten grafi\u010dni vmesnik, napisan v jeziku Dart z uporabo ogrodja Flutter. Projekt razvija tudi ogrodje Peridot za gradnjo uporabni\u0161kih vmesnikov, upravitelj paketov Fargo, standardna knji\u017enica libc, slikovni sistem Escher, Vulkan gonilnik Magma, upravljalnik komponent Scenic, datote\u010dne sisteme MinFS, MemFS, ThinFS (FAT v jeziku Go) in Blobfs, ter upravitelj razdelkov FVM. Za razvoj aplikacij je omogo\u010dena podpora za jezike C\/C++, Dart, v sistemskih komponentah pa je dovoljena tudi uporaba Rust, v omre\u017enem skladu Go, v sistemu za gradnjo jezika Python. <\/p>\n

\"Google<\/center> <\/p>\n

Pri nalaganju se uporablja sistemski upravitelj, ki vklju\u010duje appmgr za ustvarjanje za\u010detnega programskega okolja, sysmgr za oblikovanje nalagalnega okolja in basemgr za nastavitev uporabni\u0161kega okolja ter organizacijo prijave v sistem. Za zagotovitev varnosti je ponujena napredna sistemska izolacija sandbox, kjer novi procesi nimajo dostopa do jedrnih objektov, ne morejo dodeljevati pomnilnika in ne morejo izvajati kode, dostop do virov pa se ureja s sistemom prostorov imen, ki dolo\u010da razpolo\u017eljive pristojnosti. Platforma ponuja ogrodje za ustvarjanje komponent, ki predstavljajo programe, zagnane v svojem sandboxu, ki lahko komunicirajo z drugimi komponentami preko IPC.
