What is Go language?
Go is a procedural programming language that can be used for fast machine code compilation. It is a statically typed compiled language. It provides a concurrency mechanism that makes it easy to develop multi-core and networked machine-level programs. It is a fast, dynamically typed and interpreted language; it provides support for interfaces and type embedding.
The Go language was developed in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson of Google, but launched as an open source programming language in 2009.
What are the benefits of go language
It can be directly compiled into machine code and does not depend on other libraries. The version of glibc There are certain requirements, and deployment is done by just throwing a file up.
A statically typed language, but it has the feeling of a dynamic language. A statically typed language can detect most of the hidden problems during compilation. The feeling of a dynamic language is that it has many packages. It can be used and is very efficient to write.
The language level supports concurrency. This is the biggest feature of Go. It is born to support concurrency. I once said that there is a difference between natural genes and plastic surgery. We are all equally beautiful. But do you prefer plastic surgery or natural genetic beauty? Go supports concurrency in its genes. It can make full use of multiple cores and make it easy to use concurrency.
Built-in runtime supports garbage collection. This is one of the characteristics of dynamic languages. Although GC is not perfect at present, it is enough to cope with most situations we can encounter. , especially the GC after Go1.1.
It is simple and easy to learn. The authors of Go language all have C genes, so Go naturally has C genes. Then Go keywords are 25, but the expression ability is very powerful, almost Supports most of the features you've seen in other languages: inheritance, overloading, objects, etc.
Rich standard library, Go currently has a large number of built-in libraries, especially the network library is very powerful, and this is my favorite part.
Built-in powerful tools. There are many tool chains built into the Go language. The best one should be the gofmt tool, which automatically formats the code and makes team review so simple. Code The format is exactly the same, so it’s difficult to think of something different.
Cross-platform compilation. If the Go code you write does not contain cgo, then you can compile Linux applications on the window system. How to do it? Go references the code of plan9, which is information that does not depend on the system.
Embedded C support. As mentioned earlier, the author is the author of C, so Go can also directly include C code and make use of the existing rich C library.
What is Go suitable for?
Server programming, if you used C Or those things that C does, it is very suitable to use Go to do it, such as log processing, data packaging, virtual machine processing, file system, etc.
Distributed systems, database agents, etc.
Network programming, this area is currently the most widely used, including Web applications, API applications, downloads Application,
in-memory database, groupcache developed by Google some time ago, and part of couchbase constitute the
cloud platform. Currently, many foreign cloud platforms are in It is developed using Go and is partly built by CloudFoundy. The former technical director of VMare came up with the apcera cloud platform himself.

In Go, using mutexes and locks is the key to ensuring thread safety. 1) Use sync.Mutex for mutually exclusive access, 2) Use sync.RWMutex for read and write operations, 3) Use atomic operations for performance optimization. Mastering these tools and their usage skills is essential to writing efficient and reliable concurrent programs.

How to optimize the performance of concurrent Go code? Use Go's built-in tools such as getest, gobench, and pprof for benchmarking and performance analysis. 1) Use the testing package to write benchmarks to evaluate the execution speed of concurrent functions. 2) Use the pprof tool to perform performance analysis and identify bottlenecks in the program. 3) Adjust the garbage collection settings to reduce its impact on performance. 4) Optimize channel operation and limit the number of goroutines to improve efficiency. Through continuous benchmarking and performance analysis, the performance of concurrent Go code can be effectively improved.

The common pitfalls of error handling in concurrent Go programs include: 1. Ensure error propagation, 2. Processing timeout, 3. Aggregation errors, 4. Use context management, 5. Error wrapping, 6. Logging, 7. Testing. These strategies help to effectively handle errors in concurrent environments.

In Go programming, ways to effectively manage errors include: 1) using error values instead of exceptions, 2) using error wrapping techniques, 3) defining custom error types, 4) reusing error values for performance, 5) using panic and recovery with caution, 6) ensuring that error messages are clear and consistent, 7) recording error handling strategies, 8) treating errors as first-class citizens, 9) using error channels to handle asynchronous errors. These practices and patterns help write more robust, maintainable and efficient code.

Implementing concurrency in Go can be achieved by using goroutines and channels. 1) Use goroutines to perform tasks in parallel, such as enjoying music and observing friends at the same time in the example. 2) Securely transfer data between goroutines through channels, such as producer and consumer models. 3) Avoid excessive use of goroutines and deadlocks, and design the system reasonably to optimize concurrent programs.

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
