Tvrtka Microsoft predstavila<\/a><\/noindex> Na konferenciji Microsoft Build 2019 koja se odr\u017eava ovih dana predstavljena je a\u017eurirana podverzija WSL2 (Windows Subsystem for Linux), koja je namijenjena pokretanju izvr\u0161nih datoteka Linuxa unutar sustava Windows. Klju\u010dna karakteristika<\/a><\/noindex> novost u drugoj verziji je isporuka punopravnog Linux jezgra, umjesto sloja koji u stvarnom vremenu prevodi sistemske pozive Linuxa u sistemske pozive Windowsa. <\/p>\n

Beta verzija WSL2 bit \u0107e dostupna krajem lipnja u eksperimentalnim izdanjima. Windows Insider<\/a><\/noindex>Podr\u0161ka za WSL1 temeljenu na emulatoru bit \u0107e zadr\u017eana, a korisnici \u0107e je mo\u0107i koristiti uz WSL2. Za pokretanje Linux jezgra unutar Windows okru\u017eenja koristi se lagana virtualna ma\u0161ina, koja se ve\u0107 primjenjuje u Azureu. <\/p>\n

Unutar WSL2 za Windows 10 bit \u0107e ponu\u0111ena komponenta s ugra\u0111enim Linux jezgrom 4.19. Kako budu dostupne ispravke za LTS granu 4.19, jezgro za WSL2 bit \u0107e brzo a\u017eurirano putem sustava Windows Update i testirano u Microsoftovoj infrastrukturi za kontinuiranu integraciju. U WSL2 \u0107e se koristiti isto jezgro koje se koristi u Azure infrastrukturi, \u0161to \u0107e olak\u0161ati odr\u017eavanje. <\/p>\n

Sve pripremljene promjene za integraciju jezgra s WSL-om bit \u0107e objavljene pod slobodnom licencom GPLv2 i bit \u0107e proslije\u0111ene u upstream. Pripremljeni zakrpe uklju\u010duju optimizacije za smanjenje vremena pokretanja jezgra, smanjenje potro\u0161nje memorije i zadr\u017eavanje minimalnog potrebnog skupa drajvera i podsustava unutar jezgra. Predlo\u017eeno jezgro \u0107e mo\u0107i slu\u017eiti kao transparentna zamjena za emulator, koji se nudi u WSL1. Dostupnost izvornog koda omogu\u0107it \u0107e entuzijastima da prema \u017eelji izrade vlastite verzije Linux jezgra za WSL2, za \u0161to \u0107e biti pripremljena potrebna uputstva.<\/p>\n

Kori\u0161tenje ugra\u0111enog jezgra s optimizacijama iz Azure projekta omogu\u0107it \u0107e postizanje potpune kompatibilnosti s Linuxom na razini sistemskih poziva te osigurati be\u0161avnu podr\u0161ku za pokretanje Docker kontejnera u Windowsu, kao i implementirati podr\u0161ku za datote\u010dne sustave putem FUSE mehanizma. Osim toga, u WSL2 je znatno pove\u0107ana izvedba ulaz\/izlaz i operacija s datote\u010dnim sustavom, koja je ranije bila usko grlo WSL1. Na primjer, prilikom raspakiravanja komprimiranog arhiva, WSL2 je 20 puta br\u017ei od WSL1, a pri izvo\u0111enju operacija
\n \u00abgit clone\u00bb, \u00abnpm install\u00bb, \u00abapt update\u00bb i \u00abapt upgrade\u00bb od 2 do 5 puta.<\/p>\n

Iako se isporu\u010duje s Linux kernelom, WSL2 kao i prije ne\u0107e pru\u017eati gotov skup komponenata za korisni\u010dki prostor. Ove komponente se instaliraju zasebno i temelje se na verzijama razli\u010ditih distribucija. Na primjer, za instalaciju u WSL-u u Microsoft Store-u predlo\u017eeni<\/a><\/noindex> kompilaciju Ubuntu<\/a><\/noindex>, Debian GNU\/Linux, Kali Linux<\/a><\/noindex>, SUSE<\/a><\/noindex> i openSUSE<\/a><\/noindex>. Za interakciju s predlo\u017eenim Linux kernelom u Windows-u bi\u0107e potrebno dodati mali skript za inicijalizaciju u distribuciju koji mijenja proces podizanja sustava. Tvrtka Canonical ve\u0107 izjavio<\/a><\/noindex> ima namjeru osigurati punu podr\u0161ku za rad Ubuntu-a na WSL2.<\/p>\n

Dodatno se mo\u017ee istaknuti publikaciju<\/a><\/noindex> tvrtku Microsoft i emulatore terminala Windows Terminal<\/a><\/noindex>, \u010diji se izvorni kod distribuira pod MIT licencom. Uz terminal se tako\u0111er objavljuje izvorni kod originalnog su\u010delja naredbenog retka conhost.exe koji se koristi u Windows-u i implementira Windows Console API. Terminal pru\u017ea su\u010delje temeljeno na karticama i podijeljenim prozorima, u potpunosti podr\u017eava Unicode i escape sekvence za obojeni izlaz, omogu\u0107uje mijenjanje tema i dodavanje pro\u0161irenja, podr\u017eava virtualne konzole (PTY) i koristi DirectWrite\/DirectX za ubrzanje prikazivanja teksta. U terminalu je mogu\u0107e koristiti ljuske Command Prompt (cmd), PowerShell i WSL. Tijekom ljeta novi terminal \u0107e biti dostupan korisnicima Windows-a preko Microsoft Store-a.<\/p>\n
