\u00cbshte publikuar versioni i bibliotek\u00ebs libmdbx 0.13.2 (MDBX) me implementimin e nj\u00eb baze t\u00eb dh\u00ebnash t\u00eb integruar t\u00eb klas\u00ebs \u00e7el\u00ebs-vler\u00eb me performanc\u00eb t\u00eb lart\u00eb. Kodi i libmdbx shp\u00ebrndahet n\u00ebn licenc\u00ebn Apache 2.0. Mb\u00ebshteten t\u00eb gjitha sistemet operative dhe arkitekturat aktuale, si dhe Elbrusi rus 2000. P\u00ebr libmdbx ofrohet nj\u00eb API e zhvilluar p\u00ebr C++, si dhe lidhje t\u00eb mb\u00ebshtetura nga entuziast\u00ebt p\u00ebr gjuh\u00ebt Rust, Haskell, Python, NodeJS, Ruby, Go, Nim, Deno, Scala. <\/p>\n
Historikisht, libmdbx \u00ebsht\u00eb nj\u00eb ripunim i thell\u00eb i DBMS LMDB dhe tejkalon paraardh\u00ebsin e tij n\u00eb besueshm\u00ebri, gam\u00ebn e mund\u00ebsive dhe performanc\u00ebn. Krahasuar me LMDB, libmdbx i kushton v\u00ebmendje t\u00eb madhe cil\u00ebsis\u00eb s\u00eb kodit, q\u00ebndrueshm\u00ebris\u00eb s\u00eb API, testimit dhe verifikimeve automatike. Ofron nj\u00eb mjet p\u00ebr verifikimin e integritetit t\u00eb struktur\u00ebs s\u00eb DB me disa mund\u00ebsi rikuperimi. Teknologjikisht, libmdbx ofron ACID, serializim t\u00eb rrept\u00eb t\u00eb ndryshimeve dhe lexim jo bllokues me shkall\u00ebzim linear sipas nj\u00ebsive CPU. Mb\u00ebshtetet auto-kompaktifikimi, menaxhimi automatik i madh\u00ebsis\u00eb s\u00eb DB, dhe vler\u00ebsimi i volumit t\u00eb k\u00ebrkesave n\u00eb intervale (range query estimation). <\/p>\n
Ndryshimet kryesore: <\/p>\n
\n
P\u00ebrmir\u00ebsimi i shpejtuar i GC gjat\u00eb kthimit\/shtimit t\u00eb listave t\u00eb faqeve n\u00eb skenar\u00eb t\u00eb komplikuar. Krijuar dhe aktivizuar nj\u00eb mod experimental t\u00eb korrigjimit t\u00eb mbrapsht, i cili e p\u00ebrmir\u00ebsoi thelb\u00ebsisht konvergjenc\u00ebn (reduktimi i numrit t\u00eb p\u00ebrpjekjeve t\u00eb rip\u00ebrs\u00ebritura), si dhe eliminoi nj\u00eb defekt q\u00eb shkaktonte 'ciklim' gjat\u00eb regjistrimit t\u00eb transaksioneve (me kthim gabimi MDBX_PROBLEM) n\u00eb kushte t\u00eb ve\u00e7anta t\u00eb rralla.\n
N\u00eb skenaret e nd\u00ebrtimit CMake \u00ebsht\u00eb p\u00ebrfshir\u00eb standardi C23.\n
N\u00eb API-n\u00eb C++ \u00ebsht\u00eb shtuar mb\u00ebshtetje p\u00ebr transaksionet shkruese t\u00eb shumta t\u00eb ngjashme.\n
Kaluar n\u00eb edicionin e dyt\u00eb t\u00eb specifikimit t\u00eb versionimit semantik ('Semantic Versioning 2') dhe siguruar eksportimin e informacionit mbi versionin n\u00eb VERSION.json.\n
P\u00ebr t\u00eb siguruar riprodhueshm\u00ebrin\u00eb e nd\u00ebrtimeve, \u00ebsht\u00eb shtuar mb\u00ebshtetje p\u00ebr variabl\u00ebn e mjedisit SOURCE_DATE_EPOCH. Mb\u00ebshtetja p\u00ebr MDBX_BUILD_TIMESTAMP \u00ebsht\u00eb ruajtur dhe kjo variabl\u00eb ka p\u00ebrpar\u00ebsi.\n

\u00cbsht\u00eb shtuar regjistrimi i gabimeve q\u00eb kthehen nga API. Tani p\u00ebr k\u00ebt\u00eb mjafton t\u00eb caktoni nivelin e regjistrimit MDBX_LOG_DEBUG (p\u00ebr regjistrimin e gabimeve p\u00ebrve\u00e7 MDBX_NOTFOUND) ose MDBX_LOG_TRACE (p\u00ebr regjistrimin e t\u00eb gjitha gabimeve, si dhe MDBX_RESULT_TRUE).\n
Ndryshimi i sjelljes:\n
\n
\u00cbshte shtuar metoda mdbx::cursor::get_multiple_samelength() dhe e renomihet mdbx::txn::put_multiple_samelength().\n
P\u00ebr nj\u00ebtrajtshm\u00ebrin\u00eb e API-s\u00eb C++ gjat\u00eb kryerjes s\u00eb operacionit MDBX_GET_MULTIPLE tani gjithashtu kthehet vlera e vet\u00eb \u00e7el\u00ebsit.\n

Garantohet lirimi i memories nga transaksionet e leximit t\u00eb anuluara \/ t\u00eb nd\u00ebrprera q\u00eb d\u00ebrgohen n\u00eb mdbx_txn_commit(). Marr\u00ebveshja e API k\u00ebrkon q\u00eb k\u00ebto transaksione t\u00eb lirohen n\u00ebp\u00ebrmjet mdbx_txn_abort(), duke shkaktuar q\u00eb funksioni mdbx_txn_commit() t\u00eb kthej\u00eb nj\u00eb gabim n\u00eb k\u00ebto raste, pa shkat\u00ebrruar vet\u00eb transaksionet.
