On ilmunud zlib-ng 2.0 teekonna versioon, mis on m\u00e4rgitud kui projekti esimene stabiilne v\u00e4ljaanne (j\u00e4rgmiseks on saadaval ka parandav v\u00e4ljaanne 2.0.1). Zlib-ng on API tasemel \u00fchilduv zlib-iga, kuid pakub t\u00e4iendavaid optimeerimisi, mis ei ole ametlikku zlib hoidlast aktsepteeritud konservatiivsete muudatuste vastuv\u00f5tmisprotsesside t\u00f5ttu. Lisaks on pakutud uuendatud API, mis p\u00f5hineb zlib-il, kuid on kohandatud portimise lihtsustamiseks. Projekti kood on kirjutatud C keeles ja levitatakse Zlib litsentsi all. <\/p>\n

X86_64 s\u00fcsteemidel l\u00e4bi viidud testid n\u00e4itasid, et Zlib-ng pakub tihendamise operatsioonide ajal umbes 4 korda kiiremat kiiruset zlib-iga ja 2.1 korda kiiremat gzip-iga. Lauksivamisel on Zlib-ng umbes 2.4 korda kiirem zlib-ist ja 1.8 korda kiiremini gzip-ist. Signifikenet saavutati tihendamise\/lahtitihendamise j\u00f5udluse olulise paranemise t\u00f5ttu, mis p\u00f5hineb SSE*, AVX2, VSX ja Neon vektoriliste juhiste kasutamisel. <\/p>\n

Seal sisaldab Adler32 kontrollsummade arvutamise algoritmi, mis on optimeeritud SSSE3, AVX2, Neon ja VSX juhiste abiga, CRC32-B teostus, mis p\u00f5hineb PCLMULQDQ ja ACLE, t\u00e4iustatud r\u00e4sitabelid, Slide r\u00e4simise teostus SSE2, AVX2, Neon ja VSX baasil, ning v\u00f5rdlemisoperatsioonid SSE4.2 ja AVX2 baasil. Samuti on sisse viidud j\u00f5udluse parandamiseks suunatud muudatused, mida kasutatakse Intel ja Cloudflare harudes. Buffrite t\u00f6\u00f6tlemise protsess on optimeeritud. Lisatud on tugi CMake ja NMake koostamisprogrammidele. Testimiseks on kaasatud pideva integreerimise s\u00fcsteemid. <\/p>\n

Zlib-ng sisaldab optimeerimiste k\u00f5rval ka k\u00f5iki distributsioonipakettidesse kogunenud silumisi ning koodipuhastust, et eemaldada zlib's kasutatud \u00fcmbers\u00f5idulahendused, mis toetavad vanemaid kompilaatoreid ja platvorme, kuid takistavad t\u00f5husamate meetodite rakendamist (n\u00e4iteks piirangud, mis on vajalikud 16-bitiste s\u00fcsteemide ja ANSI C-ga mitte\u00fchilduvate kompilaatorite toetamiseks). Tehtud on t\u00f6\u00f6 vigade tuvastamiseks ja parandamiseks, mis on tuvastatud staatiliste anal\u00fcsaatorite, fuzzing-testi s\u00fcsteemide ja m\u00e4luprobleemide tuvastamise t\u00f6\u00f6riistadega (AddressSanitizer ja MemorySanitizer).
