Firma Google opublikowa\u0142a pe\u0142n\u0105 wersj\u0119 przegl\u0105darki internetowej Chromium dla systemu operacyjnego Fuchsia, kt\u00f3ra zast\u0105pi\u0142a w li\u015bcie aplikacji wcze\u015bniej oferowan\u0105 okrojon\u0105 przegl\u0105dark\u0119 Simple Browser, zaprojektowan\u0105 do obs\u0142ugi odr\u0119bnych aplikacji internetowych, a nie pracy z witrynami. Po\u015brednio zapewnienie wsparcia dla standardowej przegl\u0105darki internetowej potwierdza zamiar Google rozwijania Fuchsia nie tylko dla IoT i urz\u0105dze\u0144 konsumenckich, takich jak Nest Hub, ale r\u00f3wnie\u017c dla platform desktopowych. Aby zapozna\u0107 si\u0119 z aktualnym stanem rozwoju Fuchsia, mo\u017cna skorzysta\u0107 z emulatora, a tak\u017ce z testowych wersji projektu dahliaOS. <\/p>\n

Interfejs wersji Chromium dla Fuchsia jest w zasadzie podobny do wersji dla innych system\u00f3w desktopowych, z wyj\u0105tkiem pojedynczych niedor\u00f3bek i b\u0142\u0119d\u00f3w, takich jak problemy z wy\u015bwietlaniem menu kontekstowych i otwieraniem kilku okien. Tymczasem, w ostatnim czasie intensywnie pracuje si\u0119 nad usuni\u0119ciem takich problem\u00f3w, na przyk\u0142ad, kilka dni temu wprowadzono wsparcie dla wbudowanego podgl\u0105du PDF oraz mo\u017cliwo\u015b\u0107 drukowania.

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

Przypomnijmy, \u017ce system operacyjny Fuchsia rozwijany jest przez firm\u0119 Google od 2016 roku, z uwzgl\u0119dnieniem niedoci\u0105gni\u0119\u0107 w zakresie skalowalno\u015bci i bezpiecze\u0144stwa, kt\u00f3re wyst\u0119puj\u0105 w platformie Android. System opiera si\u0119 na mikroj\u0105drze Zircon, kt\u00f3re bazuje na dorobku projektu LK, rozszerzonego do zastosowania na r\u00f3\u017cnych klasach urz\u0105dze\u0144, w tym smartfonach i komputerach osobistych. Zircon rozszerza LK o wsparcie dla proces\u00f3w i bibliotek wsp\u00f3\u0142dzielonych, poziom u\u017cytkownika, system przetwarzania obiekt\u00f3w oraz model zapewnienia bezpiecze\u0144stwa oparty na capability. Sterowniki s\u0105 realizowane jako dzia\u0142aj\u0105ce w przestrzeni u\u017cytkownika dynamiczne biblioteki, \u0142adowane przez proces devhost i zarz\u0105dzane przez mened\u017cera urz\u0105dze\u0144 (devmg, Device Manager). <\/p>\n

Dla Fuchsia przygotowano w\u0142asny interfejs graficzny napisany w j\u0119zyku Dart z u\u017cyciem frameworka Flutter. Projekt rozwija r\u00f3wnie\u017c framework do budowy interfejs\u00f3w u\u017cytkownika Peridot, mened\u017cer pakiet\u00f3w Fargo, standardow\u0105 bibliotek\u0119 libc, system renderowania Escher, sterownik Vulkan Magma, mened\u017cer kompozycji Scenic, systemy plik\u00f3w MinFS, MemFS, ThinFS (FAT w j\u0119zyku Go) i Blobfs oraz mened\u017cer partycji FVM. Dla rozwoju aplikacji udost\u0119pniona jest obs\u0142uga j\u0119zyk\u00f3w C\/C++, Dart, w komponentach systemowych mo\u017cliwe jest tak\u017ce u\u017cycie Rust, w stosie sieciowym Go, a w systemie budowy j\u0119zyka Python. <\/p>\n

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

W trakcie \u0142adowania u\u017cywany jest mened\u017cer systemu, kt\u00f3ry obejmuje appmgr do stworzenia pocz\u0105tkowego \u015brodowiska programowego, sysmgr do formowania \u015brodowiska \u0142adowania oraz basemgr do konfiguracji \u015brodowiska u\u017cytkownika i organizacji logowania do systemu. Aby zapewni\u0107 bezpiecze\u0144stwo, wprowadzono zaawansowany system izolacji sandbox, w kt\u00f3rym nowe procesy nie maj\u0105 dost\u0119pu do obiekt\u00f3w j\u0105dra, nie mog\u0105 przydziela\u0107 pami\u0119ci i nie mog\u0105 uruchamia\u0107 kodu, a dost\u0119p do zasob\u00f3w realizowany jest przez system przestrzeni nazw, kt\u00f3ry okre\u015bla dost\u0119pne uprawnienia. Platforma udost\u0119pnia framework do tworzenia komponent\u00f3w, kt\u00f3re s\u0105 programami uruchamianymi w swoim sandboksie, kt\u00f3re mog\u0105 komunikowa\u0107 si\u0119 z innymi komponentami poprzez IPC.
