Shanduro 0.8.0 yelibrary uye cross-platform console utility yaburitswa. ZXC (github.com), kushandisa michina yakawanda inoshanda zvakanyanya kudzvinyirira kusina kuenzana Hazvina kurasikirwa uye zvakagadziridzwa kuti zvishandiswe pamitambo, firmware, uye mapurogiramu.
Yakanzi inokurumidza ne40%+ kupfuura LZ4 paARM64, ine huwandu hwekudzvanywa kuri nani.
Chirongwa ichi chakanyorwa neC uye chinogoverwa pasi peBSD 3 rezinesi.
Rondedzero yekuchinja:
- Shanduro yefomati ikozvino yava 5, izvo zvinokanganisa kuenderana:
- Ndakaisa LZ(+1) offset padanho refomati kuti ndibvise mavectors angangoita zero-offset attack.
- Mahedhi emusoro ikozvino anoshandisa Marsaglia xorshift algorithm.
- Maitiro matsva eLZ77 hashing uye kugadzirisa magadzirirwo etafura yehash zvinopa kuvandudzwa kukuru kwekushanda pamaitiro akasiyana-siyana, kunyanya padanho repamusoro rekumanikidzwa.
- Kuvandudzika kukuru kwemazinga ekudzvanywa kubva pa3 kusvika ku5, zvichiratidza kuwedzera kwekumhanya kwekudzvanywa kwe33-43% pane ese ari maviri x86_64 uye ARM64 architectures.
- Kuvandudzwa kunoonekwa padanho rekumanikidzwa nekukurumidza (1 ne2), nekumhanya kwakawedzera kwe10-18% pa x86_64 uye ~8-10% pa ARM64.
- Kugadzirisa zvikanganiso uye makodhi zvagadziriswazve. Iyo Python wrapper ikozvino inopa mukana kune aya maC error constants kuti ipe mishumo yezvikanganiso zviri nani uye zvechivanhu.
- Saizi yeZXC_BLOCK_SIZE haichagumiri pa1 MB. Fomati yefaira reZXC ikozvino inotsigira zviri pamutemo saizi dzemabhuroko anosvika 8 MB.
- Nzira yekugadzirisa mafaira akawanda yawedzerwa kune console utility: sarudzo ye -m (kana --multiple) inokutendera kuti ugone kugadzirisa mafaira akawanda ekupinda nemurairo mumwe chete. Faira rega rega rinogadziriswa rakazvimiririra, uye mazita emafaira anobuda anotorwa otomatiki kubva kumafaira ekupinda (semuenzaniso, file.txt inomanikidzwa kuita file.txt.xc, uye file.txt.xc inobviswa kuita file.txt).
- Chishandiso chekonsoro chinewo nzira yekugadzirisa dhairekitori rekudzokorora: sarudzo ye -r (kana --recursive) inokutendera kuti ugadzirise mafaira ese ari mumadhairekitori akatarwa uye madhairekitori awo.
- Zvimwe zvinhu zvakavandudzwa (magwaro, kuyedzwa) uye kugadziriswa kwezvikanganiso.
- Muvhezheni 0.8.1, kugadzirwa kweraibhurari ine simba chete ndiyo yakagadziriswa kuchengetedza kugona kwekushandisa shanduro dzekare dzeraibhurari.
