Druh\u00e1 verze WSL je 13kr\u00e1t rychlej\u0161\u00ed ne\u017e prvn\u00ed! Ka\u017ed\u00fd den nedost\u00e1v\u00e1te zdarma 13n\u00e1sobn\u00e9 zv\u00fd\u0161en\u00ed v\u00fdkonu. C\u00edtil jsem mrazen\u00ed a vylil n\u011bkolik slz, kdy\u017e jsem poprv\u00e9 vid\u011bl tyto v\u00fdsledky. Pro\u010d? No, hlavn\u011b jsem oplak\u00e1val ztracen\u00fd \u010das, kter\u00fd se nashrom\u00e1\u017edil za 5 let pr\u00e1ce s prvn\u00ed verz\u00ed WSL.<\/p>\n

A to nejsou jen \u010d\u00edsla. V WSL 2 instalace npm, sestaven\u00ed, balen\u00ed, prohl\u00ed\u017een\u00ed soubor\u016f, restartov\u00e1n\u00ed hork\u00fdch modul\u016f, spu\u0161t\u011bn\u00ed server\u016f - t\u00e9m\u011b\u0159 v\u0161echno, co denn\u011b pou\u017e\u00edv\u00e1m jako webov\u00fd v\u00fdvoj\u00e1\u0159, za\u010dalo fungovat v\u00fdrazn\u011b rychleji. P\u016fsob\u00ed to, jako bych se znovu posadil k Macu (nebo mo\u017en\u00e1 l\u00e9pe, proto\u017ee Apple v posledn\u00edch letech radik\u00e1ln\u011b omezuje sv\u00e9 procesory ve prosp\u011bch prodlou\u017een\u00ed v\u00fddr\u017ee baterie).<\/p>\n

Kde se bere takov\u00e1 rychlost?<\/h2>\n

\nJak dos\u00e1hli 13n\u00e1sobn\u00e9ho zv\u00fd\u0161en\u00ed v\u00fdkonu? D\u0159\u00edve, kdy\u017e jsem p\u0159em\u00fd\u0161lel o p\u0159echodu na Mac, tak\u00e9 jsem spisoval n\u011bjak\u00e9 mo\u017enosti, pravda, v\u00fdhradn\u011b na \u00farovni domn\u011bnek. Faktem je, \u017ee z\u00e1pis na disk a syst\u00e9mov\u00e9 vol\u00e1n\u00ed Linuxu st\u00e1ly pom\u011brn\u011b dost (z hlediska \u010dasov\u00fdch n\u00e1klad\u016f) kv\u016fli architektu\u0159e prvn\u00ed verze WSL. A te\u010f h\u00e1dejte, o co se modern\u00ed webov\u00fd v\u00fdvoj do zna\u010dn\u00e9 m\u00edry op\u00edr\u00e1? Ano. Kdy\u017e d\u00e1te dohromady spoustu z\u00e1vislost\u00ed a fragment\u016f k\u00f3du p\u0159i ka\u017ed\u00e9m ulo\u017een\u00ed souboru, ve skute\u010dnosti prov\u00e1d\u00edte spoustu operac\u00ed z\u00e1pisu na disk a syst\u00e9mov\u00fdch vol\u00e1n\u00ed pro des\u00edtky tis\u00edc soubor\u016f.<\/p>\n

Jakmile se o tom dozv\u00edte na vlastn\u00ed ho\u0159k\u00e9 zku\u0161enosti, je t\u011b\u017ek\u00e9 to zapomenout. Postupn\u011b upad\u00e1te do deprese, kdy\u017e si p\u0159edstav\u00edte, jak pomalu a tragicky to cel\u00e9 funguje. A vy si uv\u011bdom\u00edte, \u017ee v\u00e1\u0161 sv\u011bt u\u017e nebude, jak b\u00fdval, a n\u00e1stroj, kter\u00fd jste m\u011bli r\u00e1di, u\u017e se nezd\u00e1 u\u017eite\u010dn\u00fd a efektivn\u00ed.<\/p>\n

Na\u0161t\u011bst\u00ed se t\u00fdm WSL odv\u00e1\u017eil a \u00fapln\u011b p\u0159epsal subsyst\u00e9m. V WSL 2 byly tyto probl\u00e9my vy\u0159e\u0161eny: v\u00fdvoj\u00e1\u0159i do Windows integrovali vlastn\u00ed virtu\u00e1ln\u00ed stroj Linux a p\u0159id\u011blili s\u00ed\u0165ov\u00fdm disk\u016fm operace se soubory na VHD (Virtual Hardware Disk). Kompromis spo\u010d\u00edv\u00e1 v tom, \u017ee p\u0159i prvn\u00edm spu\u0161t\u011bn\u00ed mus\u00edte str\u00e1vit \u010das rozb\u011bhnut\u00edm virtu\u00e1ln\u00edho stroje. Tento \u010das se po\u010d\u00edt\u00e1 na milisekundy a osobn\u011b je pro m\u011b sotva znateln\u00fd. T\u011b\u0161\u00edm se na to, proto\u017ee v\u00edm, pro\u010d to d\u011bl\u00e1m.<\/p>\n

Kde nyn\u00ed budou soubory?<\/h2>\n

\nAbyste pln\u011b vyu\u017eili v\u00fdhody WSL 2, budete cht\u00edt p\u0159esunout soubory projektu z \/mnt\/c\/Users\/<\u0438\u043c\u044f \u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u0435\u043b\u044f>\/<\/b> do nov\u00e9ho domovsk\u00e9ho adres\u00e1\u0159e ~ \/ Linux<\/b> na nov\u00e9m VHD. Obsah tohoto disku m\u016f\u017eete vid\u011bt v s\u00edti p\u0159echodem na \\\\ wsl $ \\ \\ \\ home<\/b> nebo zad\u00e1n\u00edm p\u0159\u00edkazu explorer.exe<\/b> z va\u0161eho Bash shellu.<\/p>\n

To je skute\u010dn\u00fd souborov\u00fd syst\u00e9m Linux, kter\u00fd funguje a chov\u00e1 se p\u0159esn\u011b tak, jak o\u010dek\u00e1v\u00e1te. Vytvo\u0159il jsem slo\u017eku ~ \/ projects<\/b>, ve kter\u00e9 \u017eij\u00ed v\u0161echny m\u00e9 repozit\u00e1\u0159e projekt\u016f, a pot\u00e9 projekty otev\u00edr\u00e1m ve Visual Studio Code pomoc\u00ed p\u0159\u00edkazu code.<\/p>\n

A co VS Code?<\/h2>\n

\nInstalace WSL-roz\u0161\u00ed\u0159en\u00ed<\/a><\/noindex> pro vzd\u00e1len\u00fd v\u00fdvoj na VS Code (VS Code Remote - WSL) je posledn\u00edm krokem, kter\u00fd zaji\u0161\u0165uje pohodlnou pr\u00e1ci v\u00fdvoj\u00e1\u0159e. Roz\u0161\u00ed\u0159en\u00ed umo\u017e\u0148uje VS Code vykon\u00e1vat v\u0161echny sv\u00e9 operace (p\u0159\u00edkazy git, konzoli, instalaci roz\u0161\u00ed\u0159en\u00ed a tak d\u00e1le) interakc\u00ed p\u0159\u00edmo s virtu\u00e1ln\u00edm strojem Linux. To \u010din\u00ed cel\u00fd proces velmi autonomn\u00edm.<\/p>\n

Zpo\u010d\u00e1tku jsem byl trochu zklaman\u00fd nutnost\u00ed instalovat toto roz\u0161\u00ed\u0159en\u00ed, proto\u017ee jsem musel p\u0159einstalovat to, co jsem p\u0159edt\u00edm nainstaloval a nastavil. Ale nyn\u00ed si toho cen\u00edm, proto\u017ee se objevila speci\u00e1ln\u00ed vrstva vizualizace, kter\u00e1 ukazuje, v jak\u00e9m prost\u0159ed\u00ed pracuji a kde moje soubory \u017eij\u00ed. To u\u010dinilo proces webov\u00e9ho v\u00fdvoje na Windows mnohem transparentn\u011bj\u0161\u00edm a v\u00fdrazn\u011b usnadnilo pou\u017e\u00edv\u00e1n\u00ed u\u017eivatelsk\u00e9ho rozhran\u00ed pro spr\u00e1vu verz\u00ed ve VS Code.<\/p>\n

Slzy \u0161t\u011bst\u00ed a nad\u011bje na lep\u0161\u00ed budoucnost<\/h2>\n

\nNesklouznou mi\u00edc\u00ed pocit radosti p\u0159i my\u0161lence na nadch\u00e1zej\u00edc\u00ed vyd\u00e1n\u00ed Windows May 2020 Update a optimalizovan\u00e9ho Linux subsyst\u00e9mu, kter\u00fd na m\u00e9m v\u00fdkonn\u00e9m hern\u00edm po\u010d\u00edta\u010di doslova let\u00ed. Mo\u017en\u00e1 existuj\u00ed je\u0161t\u011b n\u011bjak\u00e9 probl\u00e9my, o kter\u00fdch zat\u00edm nev\u00edm, ale po Insider Preview<\/a><\/noindex> Dosp\u011bl jsem k z\u00e1v\u011bru, \u017ee t\u00fdm WSL vy\u0159e\u0161il v\u011bt\u0161inu probl\u00e9m\u016f.<\/p>\n

Krom\u011b toho bychom nem\u011bli zapom\u00ednat, \u017ee Windows Terminal<\/a><\/noindex> je tak\u00e9 skv\u011bl\u00fd! Jakoby n\u00e1s sly\u0161eli, kdy\u017e jsem si st\u011b\u017eoval na nedostatek z\u00e1lo\u017eek, JSON nastaven\u00ed a pot\u0159ebu \"c\u00edtit se cool\" ve Windows. Po\u0159\u00e1d to zn\u00ed divn\u011b, ale Windows Terminal je pravd\u011bpodobn\u011b nejlep\u0161\u00ed termin\u00e1l pro Windows.<\/p>\n

Po p\u011btilet\u00e9 pr\u00e1ci ve Windows jsem pro\u017eil hodn\u011b: neschopnost nainstalovat Rails, boj s um\u011bl\u00fdmi obaly Cygwin. Sed\u011bl jsem v prvn\u00ed \u0159ad\u011b na konferenci Build 2016, kdy\u017e Microsoft ozn\u00e1mil prvn\u00ed verzi WSL. A tehdy se mi naskytla nad\u011bje, \u017ee webov\u00fd v\u00fdvoj ve Windows kone\u010dn\u011b dos\u00e1hne nov\u00e9ho levelu. Bezpochyby je WSL 2 nejv\u011bt\u0161\u00ed zlep\u0161en\u00ed, kter\u00e9 jsem od t\u00e9 doby vid\u011bl, a vypad\u00e1 to, \u017ee jsme na prahu nov\u00e9 \u00e9ry.<\/p>\n
