Series: Practical Go Concurrency Step by Step

Post Views: 35 As the core feature of the Go language, Goroutine is the key to lightweight concurrency. It is lighter than traditional operating system threads and has lower creation cost. The default initial stack is only 2KB and supports dynamic expansion, which allows developers to easily achieve high concurrency programming. For beginners who are new to Go concurrency, understanding…

Post Views: 97 In Go language concurrent programming, goroutine is the core of efficient concurrency, but the communication and synchronization between multiple goroutines is often a place for beginners to easily step on pits. This article will take ‘calculate the factorials of 1-200 and store them into Map’ as a case, and combine the problems encountered in the learning process,…

Post Views: 47 In Go language concurrent programming, channel (pipe) is the core mechanism of communication between goroutines, which follows The design philosophy of communicating to share memory, rather than communicating through shared memory, fundamentally solves many hidden dangers of global variable lock synchronization. In the previous study, we understood the necessity of the channel through the factorial case. This…

Post Views: 67 In the previous Go concurrency review, I focused on the many drawbacks of ‘global variable lock synchronization’ through factorial cases, especially the core question of ‘there are still hidden dangers when adding locks and hibernation’ Question – Manually set the sleep time to accurately match the rhythm of the execution of the protocol. If the resource is…

Post Views: 41 In the concurrent programming of the Go language, the channel (channel) is the bridge connecting the goroutine. Many beginners often encounter “deadlock” errors when using unbuffered channels, or are confused about the blocking mechanism of the channel. This article will use a specific case to compare two different channel usage scenarios, and deeply analyze the blocking principle…

Post Views: 23 In programming learning, judging prime numbers is a classic algorithm problem. When the amount of data is small, the traditional serial loop is enough to cope; but when the amount of data is expanded to hundreds of thousands or more, how to improve the computing efficiency has become the key. Based on the Go language, this paper…

Post Views: 21 problem background In Go language, when we read data from an unclosed channel, the read operation blocks if there is no data in the channel. The traditional practice is to traverse the channel until it is closed, but in actual development, we may not be able to determine when the channel should be turned off, or when…

Post Views: 24 In the concurrent programming of Go language, goroutine is a lightweight thread implementation. However, if panic occurs in goroutine and is not captured, the entire program will crash. In this article, we will dive into two cases of using and not using Recover in depth through specific examples, and we will dive into how to properly handle…
