Multiple processes can be associat

The main purpose of software testing is to discover software errors (bugs, Will directly affect the test results. Software errors can be eliminated only when errors are handled correctly, quickly, and accurately. The software to be released meets the design objectives. In the actual software testing process, every bug must be tested and confirmed. Management processes such as identification, repair, and ver

1. process representation Linux abstracts processes into tasks and defines a struct task_struct to indicate a task. For each process, in its lifecycle, there will be a corresponding task_struct process descriptor in the memory, saving the important information required by the kernel for managing processes. A task_struct contains the following fields: By saving th

Thinkphp as a representative of the PHP framework, after years of development, by more and more companies and developers of all ages. I also take part of the time to learn this excellent framework. In the beginning of learning this framework, it is best to learn through examples, more easily combined with the actual production situation, promote the effect of learning Here I will choose the ThinkPHP3.2-based content management framework Onethink devel
