I-Haiku uhlelo olusebenzayo lomthombo wokusebenza njengamanje ekuthuthukisweni okugxile ngqo kwikhompyutha yomuntu siqu naku-multimedia.
Kukhuthazwe yi-BeOS (Yiba Uhlelo Lokusebenza), I-Haiku ifisa ukuba uhlelo olusheshayo, olusebenzayo, olusebenziseka kalula nolulula ukufunda, ngaphandle kokudebeselela amandla alo kubasebenzisi bawo wonke amazinga. Iphrojekthi yeHaiku yaziwa ngezidingo zayo maqondana nekhwalithi yezinguqulo zokusakaza.
Mayelana neHaiku
Kuze kube ngo-2009, ayikho inguqulo ehlanganisiwe ebitholakala ukulanda, ukuze kuvinjelwe ukufinyelela kubantu abanesibindi ngokwanele sokuhlanganisa uhlelo ngokwalo futhi bagweme ukudumaza abasebenzisi ngaphandle kolwazi oludingekayo lokwenza kanjalo.
Uhlelo lusekelwe ngqo kubuchwepheshe be-BeOS 5 futhi kuhloswe ngokuhambisana kanambambili nezinhlelo zalolu hlelo lokusebenza.
Ikhodi yomthombo yezinhlelo eziningi zokusebenza zeHaiku isatshalaliswa ngaphansi kwelayisense yamahhala ye-MIT, ngaphandle kweminye imitapo yolwazi, ama-codecs wezindaba, nezinto ezithathwe kwamanye amaphrojekthi.
Isistimu igxile kumakhompyutha wakho, isebenzisa i-kernel yayo, eyakhiwe ngesisekelo sokwakhiwa kwe-hybrid, elungiselelwe ukuphendula okuphezulu ezenzweni zomsebenzisi nokwenza kahle kwezicelo ezinemicu eminingi.
Uhlelo lwefayela lusebenzisa i-OpenBFS, esekela izimfanelo zefayela ezinwetshiwe, i-journaling, izikhombisi ezingama-64-bit, ukusekelwa kokugcina amathegi we-meta (kufayela ngalinye, ungagcina izimfanelo ngendlela yokhiye = inani, elenza amafayela afane nemininingwane) nezinkomba ezikhethekile ukusheshisa ukukhetha kwenhlangano yohlaka lwemibhalo kusetshenziswa izihlahla ze- "B + tree".
Kusuka kukhodi ye-BeOS, i-Haiku ifaka imenenja yefayela le-Tracker ne-Desktop Bar, amakhodi womthombo avulwa ngemuva kokumiswa kokuthuthukiswa kwe-BeOS
Abathuthukisi bafuna ukuletha i-Haiku ku-RISC-V naku-ARM
Manje Abathuthukisi bohlelo lokusebenza lweHaiku baqale ukudala amachweba okwakhiwa kwe-RISC-V ne-ARM.
Futhi ukuthi i-ARM ibaluleke kakhulu ekugcineni, Abathuthukisi beHaiku baphumelele ukudala amaphakheji wokuqalisa ukusebenzisa amafayela adingekayo endaweni encane yebhuthi.
Ngakolunye uhlangothi ukwakhiwa kwe-RISC-V igxile ekuqinisekiseni ukuhambisana ezingeni le-libc (ukusekelwa kohlobo "olude olude", olulinganiswa ngokuhlukile nge-ARM, x86, Sparc, ne-RISC-V).
Enqubeni yokusebenza emachwebeni ku-codebase enkulu, izinhlobo ze-GCC 8 kanye ne-binutils 2.32 zibuyekeziwe.
Ekwenziweni kwemikhiqizo ye-Haiku ye-RISC-V ne-ARM, iziqukathi ze-Docker sezilungisiwe, kufaka phakathi konke ukuncika okudingekayo.
Futhi, inqubekelaphambili seyenziwe ekwandiseni uhlelo lokwabiwa kwememori lwe-rpmalloc. Izinguquko ku-rpmalloc kanye nokusetshenziswa kwesilondolozi sento esehlukile kwenza ukuthi kube nokwenzeka ukunciphisa ukusetshenziswa kwememori nokunciphisa ukuhlukaniswa.
Ngenxa yalokhu, ngesikhathi senguqulo yesibili ye-beta, imvelo yeHaiku ingafakwa futhi ilayishwe ezinhlelweni ezine-256 MB ye-RAM., futhi mhlawumbe nangaphansi. Ukucwaningwa kwamabhuku nokuqondiswa kokufinyelela kwe-API sekuqalile (ezinye izingcingo zizotholakalela izimpande kuphela).
Okwamanje onjiniyela babika ukuthi amachweba alezi zakhiwo asesigabeni sokuhlola.
Manje sisesigabeni sokuhlola. Leli bekuyithuba lokuhlanza izingqinamba ezithile ze-ARM port ezibandakanya i-libstdc ++ exhunywe ngokwezibalo.
Manje sekungenzeka ukuthi kwakhiwe amaphakheji e-bootstrap, kepha ukuhlanganiswa kukaHaiku uqobo kuhlangabezana nezinkinga ezifanayo zokubopha kamuva. Okwamanje isixazululo ukusebenzisa i-LLD (kusuka ku-llvm / clang) esikhundleni sesixhumanisi sendabuko se-ld.
Ngasohlangothini lwe-RISC-V, okwamanje kubhekwe ekutholeni i-libc yethu ukuthi ifake okungenani ukuxhaswa okwanele kohlobo "long double" uhlobo oluhlukile kuzakhiwo eziningi (i-ARM isebenzisa izingcezu ezingama-64, i-x86 isebenzisa i-96, ne-sparc ne-ppc Ama-bits angama-128 kepha anezakhiwo ezahlukahlukene).
