Arch Linuxi arendajad teatasid<\/a><\/noindex>, et me muudeti pakettide pakkimisalgoritm. Varasemalt kasutati algoritmi xz (.pkg.tar.xz). N\u00fc\u00fcd on kasutusele v\u00f5etud zstd (.pkg.tar.zst). See on v\u00f5imaldanud suurendada lahtipakkimise kiirus 1300% v\u00f5rra, v\u00e4ikese pakendi suuruse t\u00f5usu arvelt (umbes 0,8%). See kiirendab s\u00fcsteemi pakettide installimise ja uuendamise protsessi.<\/p>\n

\"Arch<\/p>\n

Praegu r\u00e4\u00e4gitakse zstd-le 545 paketi t\u00f5lkimisest. \u00dclej\u00e4\u00e4nud saavad uue tihendamisalgoritmi j\u00e4rk-j\u00e4rgult, kui v\u00e4rskendusi v\u00e4lja antakse. Oluline on m\u00e4rkida, et .pkg.tar.zst formaadis paketid toetavad automaatselt pacmani (5.2) ja libarchive'i (3.3.3-1) v\u00e4rskendusi. Kui m\u00f5ni kasutajatest ei ole libarchive'i uuendanud, on uus versioon saadaval eraldi hoidlas.<\/p>\n

Algoritm zstd (zstandard) loodi 2015. aastal ja esmakordselt tutvustati seda aasta hiljem. See toetab kaotusteta tihendamist ja on suunatud kiirele tihendamisele ja dekompresseerimisele, mis on tavaliselt kiirem kui tavalised lahendused. Tihendamise koefitsient peaks olema v\u00f5rreldav v\u00f5i isegi parem kui olemasolevad lahendused. Kuidas on m\u00e4rgitud, n\u00e4itas zstd 0.6 maksimaalse tihendamise astmega sarnast tulemust nagu boz, yxz, tornado. Samas \u00fcletas see lza, brotli ja bzip2.<\/p>\n
