Versioonihalduse s\u00fcsteemi mainer Mercurial<\/a><\/noindex> t\u00f5i kokkuv\u00f5tte<\/a><\/noindex> projekti t\u00f5lkimise t\u00f6\u00f6st Python 2-st Python 3-le. Kuigi esimesed portimise katsetused tehti juba 2008. aastal ja kiirusre\u017eiimis alustati kohandamist Python 3 t\u00f6\u00f6tamiseks 2015. aastal, sai Python 3 t\u00e4isv\u00f5imekus rakendatud alles viimases Mercurial 5.2 harus. <\/p>\n

Prognoosid Python 3 pordi stabiilsuse kohta on t\u00f5siselt murettekitavad. Eelk\u00f5ige eeldatakse, et j\u00e4rgmise paari aasta jooksul tekivad koodis juhuslikud vead, kuna testid ei kata 100% koodibaasist ning paljusid probleeme ei tohi m\u00e4rgata staatilise anal\u00fc\u00fcsi k\u00e4igus, vaid need avalduvad ainult jooksutamise ajal. Lisaks j\u00e4\u00e4vad paljusid kolmandate osapoolte lisandeid ja laiendusi, mis pole Python 3-le t\u00f5lgitud, alles.
\nKuna portimise k\u00e4igus otsustati j\u00e4rk-j\u00e4rgult kohandada koodi Python 3-le, s\u00e4ilitades Python 2 toe, kasvas koodil hulgaliselt nikerdusi Python 2 ja 3 t\u00f6\u00f6kindluse tagamiseks, mida tuleb p\u00e4rast Python 2 toe l\u00f5petamist eemaldada. <\/p>\n

R\u00e4\u00e4kides Python 3 olukorrast, leiab Mercuriali mainer, et otsus edendada Python 3 n\u00f5udlikus liikuvuse pidurdustes ja esitada see uue \u00f5igemana, puuduvate t\u00e4helepanuv\u00e4\u00e4rsete uuenduste tingimustes, oli suur viga, mis tegi kogukonnale suurt kahju ja on n\u00e4ide sellest, kuidas suurtes projektides mitte v\u00e4lja minna. Kogu funktsionaalsuse j\u00e4rkj\u00e4rguline lisamine ja rakenduste j\u00e4rkj\u00e4rguline kohandamine v\u00f5imaldamine oleks pidanud toimuma, kuid Python 3 v\u00e4ljalaskmisega sunniti arendajaid koodi \u00fcmber kirjutama ja ressursse eraldama eraldi harude haldamiseks Python 2 ja Python 3 jaoks. Alles seitse aastat p\u00e4rast Python 3.0 v\u00e4ljaandmist realiseeriti Python 3.5-s v\u00f5imalused, mis v\u00f5imaldasid sujuvamalt \u00fcleminekut ja sellest \u00fches koodibaasis toimimist koos Python 2 ja Python 3-ga. <\/p>\n
