Process communication method and system, terminal equipment and medium

Abstract

The invention discloses a process communication method and system, terminal equipment and a computer readable storage medium, and the process communication method comprises the steps: constructing a local socket file address, and receiving process information sent by a dynamic link library through a mode of monitoring a preset file descriptor based on the local socket file address; judging whether the current process is allowed to run or not according to the process information; and if yes, obtaining a process response result, and sending the process response result to the dynamic link library. Acquiring and packaging process information, and binding a local socket file address generated by the server; the process information is sent to the server through the local socket file address, and a response of the server is waited; and directly exiting after receiving a process response result sent by the server. The process communication efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of process communication, and in particular, to a process communication method, system, terminal device and computer-readable storage medium. Background technique [0002] Most of the traditional process interception methods based on LD_PRELOAD preloading generally use dynamic link libraries to intercept directly; or send process information to the main process for processing, and the main process intercepts. When the main process is used for interception, it is often necessary to refer to the communication method. The traditional communication methods include: signal, udp / ip, tcp / ip, etc. [0003] The problems faced by traditional communication mechanisms are as follows: [0004] 1. The method of directly intercepting the process on the preloaded dynamic library will cause problems such as database deadlock and system freeze; [0005] 2. Since there are only 32 available signals provided by the Li...

AI Technical Summary

Problems solved by technology

[0004] 1. The method of directly intercepting the process on the preloaded dynamic library will cause problems such as database deadlock and system freeze;

[0005] 2. Since there are only 32 available signals provided by the Linux system to users, the use of signal methods will affect the normal operation of other system processes or user processes, which will seriously cause the system to fail to load programs normally when starting;

[0006] 3. The traditional udp / ip and tcp / ip communication methods will occupy the system port, and the network header needs to be added or deleted during the transmission process, the checksum needs to be calculated, the sequence number needs to be generated, and the confirmation message needs to be sent, which affects the efficiency. So it will cause the system to freeze

[0007] To sum up, the existing process communication methods have problems such as database deadlock and system freeze, which reduce the efficiency of process communication
