Pystoni projekti arendajad, kes esitavad k\u00f5rge j\u00f5udlusega Python\u2019i rakenduse, kasutades kaasaegseid JIT-kompileerimise tehnoloogiaid, on tutvustanud uut v\u00e4ljaannet Pyston 2.2 ja kuulutanud projekti naasmise avatud arenduse alla. Rakendus on suunatud saavutama k\u00f5rge j\u00f5udluse, mis l\u00e4heneb traditsiooniliste s\u00fcsteemikeelte, nagu C++, j\u00f5udlusele. Pyston 2 haru kood on avaldatud GitHubis PSFL (Python Software Foundation License) litsentsi all, mis on sarnane CPython\u2019i litsentsiga. <\/p>\n

Tulet meelde, et projekti Pyston kureeris varem ettev\u00f5te Dropbox, mis l\u00f5petas rahastamise 2017. aastal. Pystoni arendajad asutasid oma ettev\u00f5tte ja vabastasid oluliselt muudetud versiooni Pyston 2, mis kuulutati stabiilseks ja laialdaselt kasutamiseks valmis. Samuti l\u00f5petasid arendajad l\u00e4htekoodide avaldamise ja l\u00e4ksid \u00fcle ainult binaarsed kogumite pakkumisele. N\u00fc\u00fcd on otsustatud Pyston taas avatud projektiks muuta ning ettev\u00f5tte \u00e4ri mudelit, mis on seotud avatud tarkvara arendusega. Veelgi enam, kaalutakse optimeerimiste \u00fcleviimist Pystonist vaikimisi CPythoni. <\/p>\n

K\u00e4idi v\u00e4lja, et Pyston 2.2 j\u00f5udlustestides, mis hindavad rakendustele iseloomulikke koormusi, veebiserver<\/a>, on 30% kiiremini kui vaikimisi Python. Samuti m\u00e4rgitakse m\u00e4rkimisv\u00e4\u00e4rset Pyston 2.2 j\u00f5udluse suurenemist v\u00f5rreldes varasemate v\u00e4ljaannetega, mida on peamiselt saavutatud uute valdkondade jaoks optimeerimiste lisamise ning JIT ja vahem\u00e4lu mehhanismide t\u00e4iustamise abil. <\/p>\n

Peale j\u00f5udluse optimeerimise on uus versioon samuti huvitav muudatuste \u00fcleviimise t\u00f5ttu harust CPython 3.8.8. \u00dchildus tavalise Pythoniga on projekti Pyston puhul esitatud k\u00f5ige \u00fchilduvana CPythoniga alternatiivse rakendustegevusena, kuna Pyston on CPythoni p\u00f5hikoodist haru. Pyston toetab k\u00f5iki CPythoni funktsioone, sealhulgas C API, et arendada laiendusi C keeles. Pystoni ja CPythoni peamiste erinevuste seas on v\u00e4lja toodud DynASM JIT, inline-vahem\u00e4lu ja \u00fcldised optimeerimised. <\/p>\n

Pyston 2.2 muudatuste hulgas mainitakse ka CPythoni paljude silumisfunktsioonide eemaldamist koodibaasist, mis m\u00f5jutavad j\u00f5udlust negatiivselt, kuid on arendajate seas \u00fcsna v\u00e4he kasutatud. Statistika kohaselt toob silumise t\u00f6\u00f6riistade eemaldamine kaasa kiiruset\u00f5usu 2%, samas kui vaid umbes 2% arendajatest kasutavad neid funktsioone.
