Introduction

Process management and inter-process communication are implemented through the gproc module, where inter-process communication uses a local socket communication mechanism.

Usage:

import "github.com/gogf/gf/v2/os/gproc"

API Documentation:

https://pkg.go.dev/github.com/gogf/gf/v2/os/gproc

Brief Description:

1. The Manager object is a process management object that can manage multiple subprocesses (the current executing process is the parent process) simultaneously;
2. Process is a process object, representing a specific execution or acquired process resource;
3. We can use Shell, ShellExec, ShellRun to execute shell commands:
   • Shell represents a native shell command execution method with custom input and output control;
   • ShellExec will return the output result content after executing the command;
   • ShellRun will directly output the return content to standard output after executing the command;
   • We can use goroutine to achieve asynchronous execution, such as: go ShellRun(...), etc.

📄️ Process - Usage

Process management under the GoFrame framework, including how to execute Shell commands, determine the relationship between the main process and the subprocess, and the basic usage of multi-process management. Demonstrates the use of the gproc package through example code, such as creating subprocesses, managing existing processes, and implementing monitoring and control of specific processes in a Linux environment.

📄️ Process - Communication

The gproc component in the GoFrame framework is used for the mechanism of inter-process communication, including common inter-process communication methods such as signals, pipelines, shared memory, etc. It emphasizes that gproc implements a stable and general inter-process communication method through Socket, and explains basic usage examples of message transmission using the Send and Receive methods.

📄️ Process - Signal

Using the gproc component in the GoFrame framework to implement signal listening and handling, addressing the issue of redundant signal processing logic among multiple components and the inability to exit programs smoothly. By unified signal registration and callback processing, it ensures that each component can effectively receive exit signals and perform deconstruction, making signal processing logic more rigorous.

📄️ Process - Tracing

Methods for process management and tracinging using the GoFrame framework. By utilizing the OpenTelemetry specification, it supports cross-process tracinging features, making it very suitable for temporarily running processes. The example code demonstrates how to start a subprocess in the main process and pass trace information, showcasing the powerful capabilities of the GoFrame framework in process management.
