In real-world projects, there are many best practices for exceptions, and there are different suggestions for developing different types of programs in different languages. Google C + + Style mentions that Google's internal C + + code does not use exceptions, and the community has many discussions about exceptions.
As a relatively new language, the go language does not use the traditional Try...ca
At first, it was a bit weird to understand how to use defer and recover, especially when using try/catch blocks. There is a pattern that can be implemented in go with the same effect as Try/catch statement blocks. But before you need to understand the essence of defer, panic and recover.First you need to understand the role of the defer keyword, see the following code:Package Mainimport ("FMT") func main () {test ()}func minicerror (key string) error
Linux Kernel panic is a major fault that is difficult to locate and troubleshoot. Once the system has a kernel panic, there are very few logs, A common troubleshooting method-reproduction method-is difficult to implement. Therefore, the problem of kernel panic is generally a headache.There is no 10 thousand perfect solution to solve all the kernel

The go language pursues simplicity and elegance, so the go language does not support the exception of traditional try...catch...finally, because the designers of the go language think that mixing exceptions with control structures can easily confuse the code. Because developers are prone to abuse exceptions, even a small error throws an exception. In the Go language, return errors using multivalued returns. Do not
primarily for scenarios where resources need to be released. For example, open a file, and then always close it. In between open and close, there will be a lot of processing, there may be many if-else, according to different circumstances need to return early. In traditional languages, it takes one by one to call Close () before return.
And go's defer will make things simple, after open (), directly with the defer "register" a close (). Pseudo code:
f, = os.open(filename)defer f.close()do_somet

Now DDR400 memory is becoming more and more popular, some friends may not know, DDR400 specification of the memory to run stably on 400MHz, need 2.6V voltage, and DDR266 specifications to stable operation in 266MHz, only need 2.5V voltage. Many motherboard factory defaults are 2.5V, if your DDR333 or DDR400 memory to run in 333MHz or 400MHz, you need to change the memory voltage 2.6V (some motherboards are automatically recognized). I have seen a machine, Kingmax DDR400 memory runni
In my last two articles, I described in detail Error handling in the Go language, and gives you a summary of the error types, processing techniques, and design methods for the error values from two perspectives.in this article, I want to show you Another way of handling error in the Go language. However, strictly speaking, it does not deal with errors, but exceptions, and is an unexpected program exception.This program exception is called panic, and I
Go Language Bible-panic anomalies1. When the panic exception occurs, the program interrupts the operation and immediately executes the function that is delayed in the goroutine (defer mechanism)2. Not all panic exceptions come from the runtime, and calling the built-in panic function directly also throws a
3.3 DebuggerDebugging is an essential part of the application development process, so it is very important to have a good debugger, unfortunately, Go in this aspect of development is not very perfect. Currently available debuggers are GDB, the latest version is built in the integrated development environment Liteide and Goclipse, but the debugger is not flexible and difficult to operate.If you do not want to use the debugger, you can follow some of the following useful methods to achieve the pur
Defer keyword
The defer keyword allowsFunctions or statementsIt is delayed until the end of the function block, that is, when the function is about to exit, even if the function returns an error in the middle, even if it has already been panic (), even if the function has been returned, the defer object is also executed.
For example:
Func main () {A ()} func A () {println ("in a") Defer B () println ("leaving ") // B ()} func B () {println ("in B") pr
