If you are attacked by hackers, you will want to find out where the people are attacking themselves, so that we can be targeted for the prevention of hackers work. So how can this be done? This requires us to track hackers, and the hacker's "Dig" out, which has a lot of doorways, to achieve a certain degree of difficulty. This chapter introduces the common user's anti-black requirements from the discovery of hackers to trace the hacker's various methods, the purpose is to let readers after readi

Hacking Strings and redishacking for Redis code readingHacking Strings The implementation of Redis strings is contained in sds. c (sds stands for Simple Dynamic Strings ).The C structureSdshdrDeclared inSds. hRepresents a Redis string: struct sdshdr { long len; long free; char buf[];}; TheBufCharacter array stores the actual string.TheLenField stores the lengthBuf. This makes obtaining the length of a Redis string an O (1) operation.TheFreeFi
