off.In fact, to determine the drop line, only need to send or recv, if the result is zero, the drop line. However, under long connections, there may be no data exchange for a long time. Theoretically, this connection is always connected, but in reality, it is difficult to know what is wrong with the intermediate node. What's more, some nodes (firewalls) will automatically disconnect a certain amount of time without data interaction. At this time, we need our heartbeat packs to maintain long con

Memory leakage and a simple detection method, memory leakage detection1. What is Memory Leak )? Simply put, a memory space is applied for and is not released after use. Generally, the longer the program runs, the more memory it occupies, and the entire system crashes. A piece of memory applied by the program, and no pointer points to it, the memory will be leaked. 2. Hazard of Memory leakage From the perspective of user programs, memory leakage does n

I have roughly translated some of the articles, may have misunderstood the place, please correct me. It is worth mentioning that the debate in the comments section is also worth seeing. Feature Detection At first, the front-end engineers objected to browser testing, which they thought was bad because it was not a future-oriented code and could not adapt to new browsers. A better approach is to use feature detec
