How to deal with deadlock problems in C++ development
Aug 22, 2023 pm 02:24 PM
How to deal with deadlock problems in C++ development Deadlock is one of the common problems in multi-threaded programming, especially when developing in C++. Deadlock problems may occur when multiple threads wait for each other's resources. If not handled in time, deadlock will not only cause the program to freeze, but also affect the performance and stability of the system. Therefore, it is very important to learn how to deal with deadlock problems in C++ development. 1. Understand the causes of deadlocks. To solve the deadlock problem, you first need to understand the causes of deadlocks. Deadlock usually occurs when
How to debug deadlocks in C++ programs?
Jun 03, 2024 pm 05:24 PM
Deadlock is a common error in concurrent programming that occurs when multiple threads wait for locks held by each other. Deadlocks can be resolved by detecting them using a debugger, analyzing thread activity, and identifying the threads and locks involved. Ways to resolve deadlocks include avoiding circular dependencies, using deadlock detectors, and using timeouts. In practice, deadlocks can be avoided by ensuring that threads acquire locks in the same order or by using recursive locks or condition variables.
Deadlock prevention and detection mechanism in C++ multi-threaded programming

Multi-thread deadlock prevention mechanism includes: 1. Lock sequence; 2. Test and set up. The detection mechanism includes: 1. Timeout; 2. Deadlock detector. The article takes an example of a shared bank account and avoids deadlock through lock sequence. The transfer function first requests the lock of the transfer out account and then the transfer in account.
Prevention and solution of deadlock and starvation in golang function concurrency control
Apr 24, 2024 pm 01:42 PM
Deadlock and starvation in Go: Preventing and solving deadlock: Coroutines are waiting for each other and cannot perform operations. Use the runtime.SetBlockProfileRate function to detect. Prevent deadlocks: Use fine-grained locking, timeouts, and lock-free data structures to prevent deadlocks. Starvation: The coroutine continues to be unable to obtain resources, and fair locks are used to prevent starvation. Fair lock practice: Create a fair lock and wait for the coroutine to try to acquire the lock for the longest time to acquire the lock first.
