Lenktyni\u0173 b\u016bkl\u0117<\/h1>\n

Lenktyni\u0173 s\u0105lyga - tai programin\u0117s \u012frangos problema, kuri atsiranda, kai dvi ar daugiau gij\u0173 ar proces\u0173 naudojasi bendrais i\u0161tekliais arba duomenys<\/a> tuo pa\u010diu metu, tod\u0117l elgesys tampa nenusp\u0117jamas ir nenumatytas. Kitaip tariant, lenktyni\u0173 s\u0105lyga - tai laiko problema, kuri atsiranda, kai programos rezultatas priklauso nuo programos nekontroliuojam\u0173 \u012fvyki\u0173 eili\u0161kumo ir laiko.<\/p>\n

Lenktyni\u0173 s\u0105lygos gali pasireik\u0161ti bet kurioje daugiasraut\u0117je arba daugiaproces\u0117je sistemoje, \u012fskaitant operacines sistemas, \u017einiatinklio svetain\u0117<\/a> serveriai ir duomen\u0173 bazi\u0173 valdymas<\/a> sistemos. D\u0117l j\u0173 gali kilti \u012fvairi\u0173 problem\u0173, pavyzd\u017eiui, duomen\u0173 pa\u017eeidim\u0173, aklaviet\u0117s ir nenuoseklios elgsenos. Pavyzd\u017eiui, jei dvi gijos tuo pa\u010diu metu bando atnaujinti t\u0105 pat\u012f kintam\u0105j\u012f, galutin\u0117 kintamojo vert\u0117 gali b\u016bti nenusp\u0117jama, priklausomai nuo to, kokia tvarka gijos bus vykdomos.<\/p>\n

\u017dinia, lenktyniavimo s\u0105lygas labai sunku pa\u0161alinti ir atkurti, nes jos priklauso nuo subtili\u0173 laiko ir sinchronizavimo problem\u0173, kurias da\u017enai sunku nustatyti. K\u016br\u0117jai gali u\u017ekirsti keli\u0105 lenktyniavimo s\u0105lygoms naudodami tinkamus sinchronizavimo mechanizmus, pavyzd\u017eiui, u\u017eraktus, semaforus ir monitorius, kad u\u017etikrint\u0173, jog vienu metu prie bendrojo i\u0161tekliaus gali prisijungti tik viena gija ar procesas. Jie taip pat gali naudoti atomines operacijas ir atminties barjerus, kad u\u017etikrint\u0173 eili\u0161kumo apribojimus ir u\u017ekirst\u0173 keli\u0105 duomen\u0173 sugadinimui.<\/p>\n

Apibendrinant galima teigti, kad lenktyniavimo s\u0105lyga yra da\u017ena ir sud\u0117tinga problema daugiasraut\u0117se ir daugiaprocesin\u0117se programin\u0117s \u012frangos sistemose, kuri gali sukelti nenusp\u0117jam\u0105 ir nenumatyt\u0105 elges\u012f. K\u016br\u0117jai gali u\u017ekirsti keli\u0105 lenktyni\u0173 s\u0105lygoms naudodami tinkamus sinchronizavimo mechanizmus ir u\u017etikrindami eili\u0161kumo apribojimus.<\/p>","protected":false},"excerpt":{"rendered":"
