Article Introduction：In a multi-threaded environment, the behavior of PHP functions depends on their type: Normal functions: thread-safe, can be executed concurrently. Functions that modify global variables: unsafe, need to use synchronization mechanism. File operation function: unsafe, need to use synchronization mechanism to coordinate access. Database operation function: Unsafe, database system mechanism needs to be used to prevent conflicts.

Article Introduction：First, let’s understand the general principle of rsync synchronization: Rsync synchronization uses the so-called “Rsync algorithm” to synchronize the files between the local and remote hosts. This algorithm only transmits different parts of the two files instead of each time. All are transmitted in full, so the transmission speed is quite fast. The Rsync server will open a service channel (port) 873 and wait for the client Rsync connection. When connecting, the Rsync server will check whether the password (passwd) matches. If it passes the password check, the file transfer can begin. When the first connection is completed, the entire file will be transferred once, and the next time only the difference between the two files will be transferred. Next, we will do the preliminary setup and complete the task requirements first.

Article Introduction：Synchronous mode, also known as blocking mode, prevents subsequent processing by the browser and stops subsequent parsing, thus stopping subsequent file loading (such as images), rendering, and code execution. The reason why js needs to be executed synchronously is because there may be behaviors such as outputting document content, modifying dom, redirection, etc. in js, so synchronous execution is safe by default.

Article Introduction：Using multithreading in C++ can improve parallelism: Create threads: Use the std::thread class or the pthread library to create threads. Synchronize threads: Use synchronization mechanisms such as mutexes and condition variables to ensure thread safety. Practical case: For example, if multiple files are processed in parallel, multiple threads are created to process each file to improve efficiency.

Article Introduction：The principle and application of file locking in Golang. In the operating system, file locking is a mechanism used to protect files or resources from being accessed or modified by multiple processes at the same time. In Golang, the data structure in memory can be locked by using the Mutex lock provided by the sync package. However, when multiple processes are involved in reading and writing the same file, file locks need to be used to ensure data security. Consistency and security. For the type of file lock in Golang, you can use the F of the File structure provided by the os package.

Article Introduction：The C++ thread library can easily create and manage threads in network programming to achieve multi-thread processing. By using synchronization primitives such as mutexes, condition variables, and semaphores, multiple threads can safely access shared resources and avoid data races and deadlocks. In practical applications, the thread pool can be used to handle connections from multiple clients concurrently to improve server efficiency.

Article Introduction：Can be cleaned. Although delivery optimization files are useful files, users can delete them if they are no longer needed. The purpose of delivering optimized files is to improve the pressure faced by the update package server, while also improving the download speed of the client and improving the overall upgrade efficiency. Delivery optimization file cleaning may bring some consequences: 1. Some files useful for system operation may be deleted, affecting the performance and stability of the system; 2. System update efficiency may be reduced, resulting in a slower system update speed; 3. Increases disk space usage because the system may regenerate these files.
