Angifunanga ukuphawula DesdeLinux mayelana nokuthi yini eza nayo I-HTTP / 2 ikakhulu ngoba namanje angizazi zonke izinzuzo zayo, okuthi ngokuncane engikufundile, kubonakale kukuningi. Kodwa-ke, njengoba abafana be- I-Mozilla bafake ukwesekwa kwabo ku Uhlobo lweFirefox 36 ukuthi yize kungakamenyezelwa, isivele ingalandwa ku-FTP.
Yini i-HTTP / 2?
Isidlulisilwazi se-Transfer Protocol o HTTP njengoba sazi kangcono, yiprothokholi evumela ukuthengiselana kufayela le- Iwebhu yomhlaba jikelele (www). I-HTTP ichaza i-syntax nama-semantics asetshenziswa amaseva, iziphequluli, nokuningi. Ungathola okuningi imininingwane eningilizayo ku-Wikipedia.
Inkinga ngale protocol ukuthi indala kuneMethuselah, futhi ukubuyekezwa kwayo kokugcina kwaba ngo-1999. Yingakho iqembu elisebenzayo Isidlulisilwazi se-Hypertext Transfer Protocol Bis (httpbis) yefayela le- IETF (I-Internet Engineering Task Force) ithathe njengesisekelo I-SPDY (iyashesha), umthetho olandelwayo owenziwe i-Google ngo-2009, nangemva kokusebenza kanzima ngokubambisana nonjiniyela be- Mountain View, bamemezele i-HTTP / 2 njengephrothokholi enqanyuliwe.
Izinzuzo ze-HTTP / 2 ngaphezulu kwe-HTTP / 1.1
Kepha ekugcineni, ake siye kuzinzuzo ezilethwa yi-HTTP / 2 ngaphezulu kwe-HTTP / 1.1 yakudala:
I-multiplexing yokuxhuma kwe-AsynchronousI-HTTP / 2 ingasetshenziswa ngokufana, kungakhathalekile inani lezicelo, ngakho-ke kuvumela inani elikhulu lezicelo, okuthi nalo likhiqize izimpendulo eziningi zesicelo ngasinye ngasikhathi sinye. Le protocol yenzelwe ukuthi isetshenziswe kumasayithi anamazinga aphezulu ethrafikhi, ibavimbela ekushayisaneni, okusiholela enenzuzo yesibili.
Ukucindezelwa kukanhlokweni namapayipi okuphendula impendulo: Njengoba izihloko zesicelo se-HTTP zicindezelwe, kudingeka umkhawulokudonsa omncane. Ngakho-ke umthwalo uzoshesha kakhulu futhi izicelo eziningi ngasikhathi sinye zingathunyelwa ngasikhathi sinye.
Ukubethela: Lesi sici siphoqelelwe yiFirefox neGoogle Chrome ukwamukela umthetho olandelwayo omusha, okusho ukuthi esikhathini esizayo esingekude kakhulu, sizobona amanye amasayithi amaningi esebenzisa ukuxhumana okuphephile.
Ngokufingqa, okusithandayo ukuthi nge-HTTP / 2 sizokwazi ukuzulazula kumawebhusayithi wethu owathandayo ngokushesha okukhulu, ngaphandle kokuphahlazeka, ikakhulukazi kumadivayisi eselula anenkumbulo (noma enezinkumbulo ezingaphansi kwe-RAM kunekhompyutha.
Ngabe iFirefox 36 isilethelani?
Yebo, iFirefox 36 isilethela ukusekelwa kwe-HTTP / 2 (okungakaqaliswa okwamanje, okungenani hhayi emhlabeni jikelele), Izandiso Zomthombo Wezindaba (MSE) ukuphatha ukukhiqizwa kabusha kwendabuko ku-HTML5 ku-Youtube, ukulungiswa ku-HTML5, ukuvumelanisa izinqamuleli kuthebhu entsha, indlela entsha yokubona Okuncamelayo nokuningi, izinto eziningi ezingakwazi bheka lapha.
Uma ungafuni ukulinda ukuthi kufakwe ekusabalaliseni kwakho unhlokweni, nazi izixhumanisi:
Qaphela: I-Google Chrome nayo inokwesekwa kwe-HTTP / 2
Ukuhlola iFirefox 36 😛
Lapha kusuka ku-Windows konke KULUNGILE (kulindwe i-Iceweasel 36 ukuthi iphume kusasa). Ekugcineni amavidiyo aku-Youtube adlala kahle, kepha okwamanje iFirefox iyangisindisa kudeshi.
Ukuhlola i-Iceweasel 36 kusuka kuDebian Wheezy. Ngokusobala, isasebenzisa i-GStreamer ukudlala amavidiyo ku-H.264, i-MSE ayizange iyisebenzise futhi i-EME iyikhubaze (ngiyabonga ubuhle), futhi ihlaya ukuthi i-Youtube ayisethuli ngokuzenzakalela isidlali ku-HTML5 futhi iyaqhubeka nokubuyela emuva ku I-Flash Player.
Noma kunjalo, nayi ifayili le- Iceweasel 36 changelog.
Nginombuzo mayelana ne-Asynchronous Connection Multiplexing
Lokhu ngeke kube nomthelela omubi kwezokuphepha, ngenxa yokuhlaselwa kohlobo lwe-ddos, noma umane nje ukuthi amaseva "anqunyelwe" alahlwa kalula.
Yilokho ukukhathazeka enginakho okwamanje.
f5 f5 f5 kanye kabum !!! awusadingi loic ukulahla umngane wakho server
Ngokuphambene nalokho, i-multiplexing izovumela amaseva ukuthi aphathe inani elikhulu lokuxhumeka ngasikhathi sinye kokusebenzisa le ndlela, ngoba ekuxhumaneni kwangempela ngakunye kuseva-iklayenti le-HTTP2, imifudlana eminingi yedatha ingaphathwa ngaphansi kohlelo oluthile lokulawula. Akukhona ukuthi ukuxhumana okuningi okunomlingo kuyavulwa (okuyikho kanye okwenzekayo manje, lapho kuvulwa ikhasi ukuxhumana okuningi kwe-HTTP kuvulwa ukulayisha okuqukethwe kwayo), kepha ukuthi ukuxhumana okufanayo futhi kuphela okuzokuvumela ukuthi ujabulele okuningi ukugeleza kwedatha nezinsizakalo.
Isibonelo esihle kakhulu sokuthi amasu we-multiplexing asebenza kuse-telephony, lapho kade isebenzisa le ndlela iminyaka eminingi ukukhulisa inani lokuxhuma nge-radiobase ngayinye futhi ngesikhathi esifanayo yandisa isivinini sayo, sikuqonde lokho; I-2G, i-3G ne-4G inezinhlelo ezisebenzisa kakhulu lezi zinhlobo zamasu.
Hhayi-ke manje asilinde lokhu kube okujwayelekile kanye ne-nginx nabanye ukuze bakusebenzise ohlangothini lweseva. Lokhu kuvuselelwa kweprothokholi kuyajabulisa futhi singathanda ukukuthola okwamanje, kepha sekuyisikhathi eside kuza.
Yebo, kusuka ku-NGinx angicabangi ukuthi kunenkinga: http://www.serverwatch.com/server-news/nginx-gearing-up-for-http2.html
Qaphela: I-Google Chrome nayo inokwesekwa kwe-HTTP / 2
Ngakho-ke bane-http2 futhi: i-Opera, iChromium, iMaxthon, ne-ETC ende. esebenzisa injini ye-Chrome kwesokudla? ...
Ilungele i-FF ngokungasali emuva kulokhu.
Impela! Noma okungenani ngombono.
Sawubona Elav!
Mhlawumbe ukuhunyushwa okuyiphutha kwami.
"Ngamafuphi, okusithandayo ukuthi nge-HTTP / 2 sizokwazi ukubhekabheka amawebhusayithi wethu owathandayo ngokushesha okukhulu, ngaphandle kokuphahlazeka, ikakhulukazi kusuka kumadivayisi eselula anenkumbulo (noma enezinkumbulo ezingaphansi kwe-RAM kunekhompyutha."
Ukuba ne-RAM engaphezulu noma encane kunomthelela muni kulokho okushiwo ijubane lokudlulisa ku-protocol ye-HTTP / 2?
Ngabe usho ukuthi njengoba kunedatha encane elandiwe, kuzothatha imemori encane? Kepha angiqondanga.
Hug!
Nami ngike ngakuqonda okunje. Kucatshangwa ukuthi lapho ukucutshungulwa kokuqukethwe kuphakama, ngenxa yenkinga yokunikeza, kuphakama ukusetshenziswa kwezinsizakusebenza zeklayenti. Noma yilokho engikuqondayo ngakho konke lokhu 😀
Ngabe iMozilla ilungise inkinga yokusetshenziswa kwememori?
Ozithobayo. Unesixazululo lapha:
http://www.ubuntuleon.com/2015/02/en-busca-de-la-cache-de-fuego-aka.html
Ngokusobala, yebo, ngoba ngiyayihlola kusuka ku-netbook yami futhi isebenza kahle njenge-Opera Blink kuhlukaniso lweWindows. Kusasa i-Iceweasel 36 izotholakala, futhi ngizokutshela ngokuningiliziwe ukuthi kuhambe kanjani.
Kade ngihlola i-iceweasel 36 isikhashana futhi kunezinto ezimbalwa engingazithandi.
1. Okokuqala ukuvela kokukhangisa ku-Hello, ngama-logo angumthombo ovulekile futhi ngaphandle kokukhetha ukukhetha ukuwabona noma cha. Okusho ukuthi, yize amaphakheji e-firefox noma e-iceweasel engalethi izithombe zelogo, isiphequluli lapho usilayisha siyazifaka ngaphandle kokukunikeza noma ikuphi ukukhetha, okungaholela ekubuzeni indawo yazo kumakhosombe womuntu wephakethe le-firefox.
2. Owesibili uhlobene nenjini yokusesha, uma umuntu echofoza engilazini yokukhulisa futhi kungekho mbhalo, imenyu enezinjini zokusesha ezahlukahlukene ayiveli, futhi, ngemuva kokwenza usesho ibuyela enjini yokusesha ezenzakalelayo, iphuzu liyacasula futhi linzima.
Ngokwephuzu lokuqala, yize ngivumela ngikutshele ukuthi iFirefox Hello isebenzisa ubuchwepheshe bewebhu futhi njengoba iseva kaMozilla esetshenziswa e-Iceweasel, akunakwenzeka ukususa ilogo yomxhasi (okuyiTelefonica).
Ngakolunye uhlangothi, ngiyabona ukuthi bayisusile ilogo esifundeni sokucinga, ngoba ezinhlotsheni ezedlule babe nezinkinga zokukhombisa uphawu (kokubili ekhasini eliyisiqalo elizenzakalelayo kanye nasengxenyeni ethi "ithebhu entsha", ngaphezu kokushoda Uhlelo lwe-MSE ne-H.264 codec enikezwe yi-CISCO (bonga okuhle ukuthi i-YouTube ingalungiselelwa ukubuka ku-HTML5 ngokuzenzakalela).
Futhi into eyodwa: ayisasebenzisi i-VP8 codec ngokuzenzakalela, kepha isebenzisa i-GStreamer ukudlala amavidiyo we-H.264 kusidlali se-HTML5 ku-Youtube (Kungani ungasebenzisi i-VP9 codec?).
PS: Ukuphawula kwangaphambilini ngaphawulwa njengogaxekile. I-akismet yayingcono.
Izindaba ezinhle
kuyamangalisa ukuthi ubuchwepheshe buqhubekela kanjani phambili
