\u00cbsht\u00eb prezantuar versioni 5.4.0 i bibliotek\u00ebs s\u00eb menaxhimit t\u00eb memories jemalloc, e cila ofron nj\u00eb implementim alternativ t\u00eb funksioneve malloc, t\u00eb optimizuar p\u00ebr t\u00eb ulur fragmentimin dhe p\u00ebr pun\u00eb n\u00eb sisteme shum\u00ebprocesorike. P\u00ebr t\u00eb zgjidhur problemet me bllokimet n\u00eb sistemet shum\u00ebb\u00ebrthamore, n\u00eb jemalloc p\u00ebrdoret nj\u00eb zon\u00eb e ve\u00e7uar e alokimit t\u00eb memories p\u00ebr \u00e7do b\u00ebrtham\u00eb CPU, gj\u00eb q\u00eb mund\u00ebson shkall\u00ebzim linear me rritjen e numrit t\u00eb rrjedhave. <\/p>\n
N\u00eb qershor 2025, autori i projektit ndaloi mir\u00ebmbajtjen dhe e kaloi depozit\u00ebn e jemalloc n\u00eb regjim arkivimi, por n\u00eb mars t\u00eb k\u00ebtij viti zhvillimi u rifillua nga kompania Meta, e cila p\u00ebrdor jemalloc n\u00eb infrastruktur\u00ebn e saj. Fillimisht, biblioteka u zhvillua p\u00ebr FreeBSD dhe p\u00ebrdoret n\u00eb k\u00ebt\u00eb OS si parazgjedhje q\u00eb nga viti 2005. Kodi i bibliotek\u00ebs \u00ebsht\u00eb shkruar n\u00eb C dhe shp\u00ebrndahet sipas licenc\u00ebs BSD. <\/p>\n
Nd\u00ebr ndryshimet: <\/p>\n
\n
\u00cbsht\u00eb thjeshtuar logjika e mbushjes dhe pastrimit t\u00eb tcache (Thread Local Cache), si edhe dispatchimi i alokimit t\u00eb memories.\n
Jan\u00eb unifikuar alokator\u00ebt e faqeve t\u00eb memories PAC (Page Allocator Classic) dhe HPA (Huge Page Allocator). \u00cbsht\u00eb hequr mekanizmi i nd\u00ebrlikuar i thirrjeve indirekte p\u00ebrmes vtable (PAI vtable).\n
P\u00ebr t\u00eb thjeshtuar mir\u00ebmbajtjen dhe zgjerimin e platformave, t\u00eb gjitha operacionet e varura nga platforma jan\u00eb zhvendosur n\u00eb skedar\u00eb header t\u00eb ve\u00e7ant\u00eb.\n
\u00cbsht\u00eb thjeshtuar dispatchimi i komandave mallctl, si edhe \u00ebsht\u00eb ripunuar infrastruktura p\u00ebr gjenerimin dhe paraqitjen e statistikave.\n
\u00cbsht\u00eb shtuar flamuri EXTENT_ALLOC_FLAG_PINNED, i cili lejon sh\u00ebnimin e zonave t\u00eb pamapueshme t\u00eb memory mapping q\u00eb nuk mund t\u00eb zhvendosen, si p.sh. faqet HugeTLB, p\u00ebr rip\u00ebrdorim prioritar. P\u00ebr t\u00eb marr\u00eb statistika mbi p\u00ebrdorimin e memories s\u00eb fiksuar, jan\u00eb shtuar nd\u00ebrfaqe t\u00eb reja mallctl: stats.pinned, stats.arenas..pinned, stats.arenas..extents..npinned, stats.arenas..extents..pinned_bytes dhe stats.arenas..mutexes.extents_pinned.{counter} .\n
P\u00ebrmbajtja e statistikave malloc \u00ebsht\u00eb sinkronizuar n\u00eb formatet e lexueshme dhe JSON.\n
Jan\u00eb hequr parametrat e vjet\u00ebruar lg_tcache_nslots_mul, tcache_nslots_small_min, tcache_nslots_small_max, tcache_nslots_large, tcache_gc_delay_bytes, lg_tcache_flush_small_div dhe lg_tcache_flush_large_div. <\/ul>\n
