1. Thread Pool Design Concept: A thread pool is a mechanism for managing thread resources, where a certain number of threads are created in advance. When a task is submitted, a thread is obtained from the pool to execute the task, and after the task is completed, the thread is not destroyed but returned to … Read more
In multithreaded programming, synchronization mechanisms are essential for ensuring safe access to shared resources.Mutexes and Spin Locks, as the two most classic types of locks, are widely used in various systems and frameworks.This article will comprehensively analyze the differences between the two from the perspectives of underlying implementation principles, waiting strategy differences, performance overhead analysis, … Read more
In practical GDB debugging experience, multithreaded debugging is more common, as many system designs are based on threads. Therefore, when a binary has issues, they often reside in a specific thread. At this point, GDB needs to correctly switch to the corresponding thread and then run. If you simply switch to a specific thread and … Read more
In the C language, <span>volatile</span> is a type specifier that informs the compiler that the variable it modifies may be changed by factors outside the program (such as hardware, interrupt service routines, etc.). Therefore, the compiler should not optimize this variable, and it must read its value from memory each time it is used, rather … Read more
In modern computer architecture, concurrency programming has become a key technology for enhancing application performance. The C++11 standard introduced powerful support for concurrency programming, allowing developers to write multithreaded programs in a more intuitive and safer manner. Among these, <span>std::thread</span> and <span>std::async</span> are two of the most important tools for concurrency programming. 1. Why is … Read more
We know that ptrace frequently issues PTRACE_GETREGS and PTRACE_SETREGS commands, modifying the PC register, allowing the process to be controlled by gdb and execute related commands at the trace point. This article uses a simple program to demonstrate basic debugging tasks using gdb. What to Debug Based on the understanding of ptrace, we can summarize … Read more
Alternatives to Threads Before starting to write multithreaded applications, let’s do a quick review: generally speaking, multithreading is a good thing. However, due to the limitations of Python’s GIL, multithreading is more suitable for I/O-bound applications (I/O releases the GIL, allowing for more concurrency) rather than CPU-bound applications. For the latter case, to achieve better … Read more
