1、效率高(多个进程共享一块内存的数据) 2、帮我们处理好锁问题。这就是mutiprocessing模块为我们提供的基于消息的IPC通信机制:队列和管道。 队列和管道都是将数据存放于内存中,队列又是基于(管道+锁)实现的,可以让我们从复杂的锁问题中解脱出来,我们应该尽量避免使用共享数据,尽可能使用消息传递和队列,避免处理复杂...
In Python, sockets allow for inter-process communication (IPC) over networks. This tutorial provides a comprehensive guide on creating socket servers and clients, handling multiple connections, and managing errors in Python’s socket module.By the end of this tutorial, you’ll understand that:...
In #12800, we added support for both VERCEL_IPC_FD and VERCEL_IPC_PATH while migrating from the former to the latter. The migration has now been completed, so we can remove the old VERCEL_IPC_FD lo...
