Advanced Time Manipulation with GDB

a year ago

Introduction to advanced time travel debugging with GDB, including creating time loops and changing the past without paradoxes.
Example of a bug in a game's random hit chance code, demonstrating unexpected behavior (getting zero hits when at least one should always succeed).
Explanation of time loops for debugging sporadic failures, using breakpoints and GDB commands to automate testing and recording.
Steps to set up a time loop in GDB, including identifying key locations, setting breakpoints, and using commands to automate the process.
Discussion on changing the past in GDB, including limitations and a workaround using 'record stop' to modify past execution states.
Combining time loops and past modification techniques to optimize debugging, especially for slow-starting programs.
Final thoughts on the versatility of reverse debugging and encouragement to explore more debugging techniques.
