Intel har offentliggjort en ny version af v\u00e6rkt\u00f8jet ControlFlag 1.2, som g\u00f8r det muligt at identificere fejl og anomalier i kildekoder ved hj\u00e6lp af et maskinl\u00e6ringssystem, der er tr\u00e6net p\u00e5 et stort volumen af eksisterende kode. I mods\u00e6tning til traditionelle statiske analysatorer anvender ControlFlag ikke faste regler, som kan v\u00e6re sv\u00e6re at forudse alle mulige variationer, men bygger p\u00e5 statistikken over brugen af forskellige sproglige konstruktioner i et stort antal eksisterende projekter. Koden til ControlFlag er skrevet i C++ og er open source under MIT-licensen. <\/p>\n

Den nye udgivelse er bem\u00e6rkelsesv\u00e6rdig for implementeringen af fuld support til opdagelse af anomalier og l\u00e6ring baseret p\u00e5 typiske kodeeksempler for C++. Tidligere versioner havde lignende st\u00f8tte for C og PHP. Systemet er velegnet til at identificere forskellige typer problemer i koden, fra at opdage tastefejl og forkerte typekombinationer til at afsl\u00f8re anomalier i betingede udtryk «if» og manglende NULL-v\u00e6rdikontroller i pegepinde. Systemet tr\u00e6nes ved at opbygge en statistisk model baseret p\u00e5 eksisterende kode fra \u00e5bne projekter p\u00e5 C, C++ og PHP, der er offentliggjort p\u00e5 GitHub og lignende offentlige repositories. <\/p>\n

Under tr\u00e6ningsfasen identificerer systemet typiske m\u00f8nstre i kodens konstruktioner og bygger et syntaktisk tr\u00e6, der forbinder disse m\u00f8nstre, hvilket afspejler den udf\u00f8relsesm\u00e6ssige flow i programmet. I sidste ende dannes der et reference beslutningstr\u00e6, der samler udviklingserfaringer fra alle analyserede kildekoder. For den kontrollerede kode udf\u00f8res en lignende proces for at identificere m\u00f8nstre, der sammenlignes med reference beslutningstr\u00e6et. Store afvigelser fra n\u00e6rliggende grene indikerer tilstedev\u00e6relsen af en anomali i den kontrollerede skabelon. <\/p>\n
