\nAhoj, Habr! V Badoo aktivn\u011b pracujeme na v\u00fdkonnosti PHP<\/a><\/noindex>, proto\u017ee m\u00e1me dost velk\u00fd syst\u00e9m na tomto jazyce a ot\u00e1zka v\u00fdkonnosti je ot\u00e1zkou \u00faspory pen\u011bz. P\u0159ed v\u00edce ne\u017e deseti lety jsme vytvo\u0159ili PHP-FPM, kter\u00e9 zpo\u010d\u00e1tku p\u0159edstavovalo sadu patch\u016f pro PHP, a pozd\u011bji se stalo sou\u010d\u00e1st\u00ed ofici\u00e1ln\u00ed distribuce.<\/p>\n

V\u011bt\u0161inu p\u0159\u00edpad\u016f spou\u0161t\u00edte aplikaci pomoc\u00ed kombinace webov\u00e9ho serveru nginx a PHP-FPM.

Pod\u00edvejme se, jak PHP-FPM vykon\u00e1v\u00e1 k\u00f3d aplikace. Kdy\u017e p\u0159ijde \u017e\u00e1dost, PHP-FPM inicializuje pod\u0159\u00edzen\u00fd PHP proces a detaily \u017e\u00e1dosti p\u0159ed\u00e1v\u00e1 jako sou\u010d\u00e1st jeho stavu (_GET, _POST, _SERVER atd.). <\/p>\n

Stav se b\u011bhem vykon\u00e1v\u00e1n\u00ed PHP skriptu nem\u016f\u017ee m\u011bnit, a proto lze z\u00edskat novou sadu vstupn\u00edch dat pouze jedn\u00edm zp\u016fsobem: vy\u010di\u0161t\u011bn\u00edm pam\u011bti procesu a jeho novou inicializac\u00ed.<\/p>\n

Tento model vykon\u00e1v\u00e1n\u00ed m\u00e1 mnoho v\u00fdhod. Nemus\u00edte se p\u0159\u00edli\u0161 ob\u00e1vat spot\u0159eby pam\u011bti, v\u0161echny procesy jsou zcela izolov\u00e1ny, a pokud jeden z nich \"um\u0159e\", bude automaticky znovu vytvo\u0159en, co\u017e nijak neovlivn\u00ed ostatn\u00ed procesy. Tento p\u0159\u00edstup m\u00e1 v\u0161ak tak\u00e9 nev\u00fdhody, kter\u00e9 se projevuj\u00ed p\u0159i pokusu o \u0161k\u00e1lov\u00e1n\u00ed aplikace.<\/p>\n

Nev\u00fdhody a neefektivnost b\u011b\u017en\u00e9ho PHP prost\u0159ed\u00ed<\/h3>\n

\nPokud se zab\u00fdv\u00e1te profesion\u00e1ln\u00edm v\u00fdvojem v PHP, v\u00edte, \u010d\u00edm za\u010d\u00edt nov\u00fd projekt - v\u00fdb\u011brem frameworku.

Frameworky jsou skv\u011bl\u00e9!<\/p>\n

Ale v\u0161echno m\u00e1 svou cenu.

Ale nejhor\u0161\u00ed na tom je, \u017ee po vykon\u00e1n\u00ed ka\u017ed\u00e9ho \u00fakolu mus\u00edte v\u0161e vyresetovat a za\u010d\u00edt znovu: ve\u0161ker\u00fd k\u00f3d, kter\u00fd jste pr\u00e1v\u011b iniciovali, se st\u00e1v\u00e1 bezcenn\u00fdm, proto\u017ee u\u017e s n\u00edm nebudete schopni zpracovat dal\u0161\u00ed \u017e\u00e1dost. \u0158ekn\u011bte to jak\u00e9mukoli program\u00e1torovi, kter\u00fd p\u00ed\u0161e v jin\u00e9m jazyce, a uvid\u00edte na jeho tv\u00e1\u0159i zmaten\u00ed.<\/p>\n

Ale nakonec je stejn\u011b t\u0159eba v\u0161echno aplikaci resetovat a za\u010d\u00edt znovu, znova a znova. (Pozn\u00e1mka p\u0159ekladatele: \u010d\u00e1ste\u010dn\u011b tento probl\u00e9m vy\u0159e\u0161\u00ed vyd\u00e1n\u00ed preload<\/a><\/noindex> PHP 7.4)<\/p>\n

V d\u016fsledku toho m\u00e1me funk\u010dn\u00ed PHP server, kter\u00fd je schopen zpracov\u00e1vat jak\u00e9koli dotazy, kter\u00e9 jsou p\u0159edlo\u017eeny bin\u00e1rn\u011b.<\/p>\n

Aby na\u0161e aplikace za\u010dala fungovat jako webov\u00fd server, museli jsme vybrat spolehliv\u00fd PHP standard pro reprezentaci jak\u00fdchkoli p\u0159\u00edchoz\u00edch HTTP dotaz\u016f. V na\u0161em p\u0159\u00edpad\u011b jednodu\u0161e p\u0159evedeme<\/a><\/noindex> net\/http dotaz z Go do form\u00e1tu PSR-7<\/a><\/noindex>, aby byl kompatibiln\u00ed s v\u011bt\u0161inou dostupn\u00fdch dne\u0161n\u00edch PHP r\u00e1mc\u016f.<\/p>\n

Jeliko\u017e je PSR-7 pova\u017eov\u00e1n za nem\u011bnn\u00fd (n\u011bkdo by mohl \u0159\u00edci, \u017ee to technicky nen\u00ed pravda), musej\u00ed v\u00fdvoj\u00e1\u0159i ps\u00e1t aplikace, kter\u00e9 v z\u00e1sad\u011b nenakl\u00e1daj\u00ed s dotazem jako s glob\u00e1ln\u00ed entitou. To se skv\u011ble spojuje s konceptem dlouhotrvaj\u00edc\u00edch PHP proces\u016f. Na\u0161e kone\u010dn\u00e9 proveden\u00ed, kter\u00e9 je\u0161t\u011b nem\u00e1 n\u00e1zev, vypadalo takto:<\/p>\n

P\u0159edstavujeme RoadRunner \u2014 vysoce v\u00fdkonn\u00fd server PHP aplikac\u00ed<\/a><\/noindex><\/h3>\n

\nNa\u0161\u00edm prvn\u00edm testovac\u00edm \u00fakolem byl API backend, na kter\u00e9m se periodicky nepredikovateln\u00e9 vyskytovaly v\u00fdkyvy dotaz\u016f (mnohem \u010dast\u011bji ne\u017e obvykle). I kdy\u017e v\u011bt\u0161inou mo\u017enosti nginx sta\u010dily, pravideln\u011b jsme se setk\u00e1vali s chybou 502, proto\u017ee jsme nemohli dostate\u010dn\u011b rychle vyv\u00e1\u017eit syst\u00e9m pod o\u010dek\u00e1van\u00fdm n\u00e1r\u016fstem z\u00e1t\u011b\u017ee.<\/p>\n

Abychom nahradili toto \u0159e\u0161en\u00ed, na za\u010d\u00e1tku roku 2018 jsme nasadili n\u00e1\u0161 prvn\u00ed PHP\/Go server aplikac\u00ed. A hned jsme z\u00edskali \u00fa\u017easn\u00fd efekt! Nejen\u017ee jsme se zcela zbavili chyby 502, ale tak\u00e9 jsme mohli sn\u00ed\u017eit po\u010det server\u016f o dv\u011b t\u0159etiny, \u010d\u00edm\u017e jsme u\u0161et\u0159ili spoustu pen\u011bz a l\u00e9k\u016f na bolesti hlavy pro in\u017een\u00fdry a produktov\u00e9 mana\u017eery.<\/p>\n

V polovin\u011b roku jsme vylep\u0161ili na\u0161e \u0159e\u0161en\u00ed, zve\u0159ejnili ho na GitHubu pod licenc\u00ed MIT a pojmenovali RoadRunner<\/a><\/noindex>, co\u017e podtrhuje jeho neuv\u011b\u0159itelnou rychlost a efektivitu.<\/p>\n

Jak m\u016f\u017ee RoadRunner zlep\u0161it v\u00e1\u0161 v\u00fdvojov\u00fd stack<\/h3>\n

S pomoc\u00ed komunit PHP a Go jsme zv\u00fd\u0161ili stabilitu \u0159e\u0161en\u00ed, v n\u011bkter\u00fdch testech jsme zv\u00fd\u0161ili v\u00fdkon aplikac\u00ed a\u017e 40kr\u00e1t, vylep\u0161ili jsme n\u00e1stroje pro lad\u011bn\u00ed, implementovali integraci s frameworkem Symfony a p\u0159idali podporu pro HTTPS, HTTP\/2, pluginy a PSR-17.<\/p>\n

\nN\u011bkte\u0159\u00ed lid\u00e9 jsou st\u00e1le uv\u011bzn\u011bni v zastaral\u00e9m pohledu na PHP jako na pomal\u00fd a objemn\u00fd jazyk, vhodn\u00fd pouze pro psan\u00ed plugin\u016f pro WordPress. Tito lid\u00e9 dokonce mohou \u0159\u00edct, \u017ee PHP m\u00e1 takov\u00e9 omezen\u00ed: kdy\u017e se aplikace stane dostate\u010dn\u011b velkou, mus\u00edte zvolit vysp\u011blej\u0161\u00ed jazyk a p\u0159epsat nahromad\u011bn\u00fd k\u00f3d, kter\u00fd m\u00e1te po mnoho let.<\/p>\n

Na to v\u0161echno bychom cht\u011bli odpov\u011bd\u011bt: zamyslete se znovu. Domn\u00edv\u00e1me se, \u017ee pouze vy si ur\u010dujete n\u011bjak\u00e1 omezen\u00ed pro PHP. M\u016f\u017eete str\u00e1vit cel\u00fd \u017eivot p\u0159echody z jednoho jazyka na druh\u00fd, abyste na\u0161li ide\u00e1ln\u00ed kombinaci pro va\u0161e pot\u0159eby, nebo m\u016f\u017eete za\u010d\u00edt vn\u00edmat jazyky jako n\u00e1stroje. Zd\u00e1nliv\u00e9 nev\u00fdhody jazyka jako PHP mohou b\u00fdt ve skute\u010dnosti p\u0159\u00ed\u010dinou jeho \u00fasp\u011bchu. A pokud ho spoj\u00edte s jin\u00fdm jazykem jako Go, vytvo\u0159\u00edte mnohem mocn\u011bj\u0161\u00ed produkty, ne\u017e kdybyste se omezili na pou\u017e\u00edv\u00e1n\u00ed jen jednoho jazyka.<\/p>\n

Pracov\u00e1n\u00edm se spojen\u00edm Go a PHP m\u016f\u017eeme \u0159\u00edci, \u017ee jsme si je zamilovali. Nepl\u00e1nujeme ob\u011btovat jeden ve prosp\u011bch druh\u00e9ho - naopak budeme hledat zp\u016fsoby, jak je\u0161t\u011b v\u00edce vyu\u017e\u00edt tuto dvojitou technologii.<\/p>\n
