Abstract

The embodiment of the invention discloses a method for inter-process communication and a related device, which are used for solving the problem of unreliable communication content between a parent process and a child process in the prior art. A method for implement an embodiment of that invention includes creatING a shared file in a pressing machine, wherein the shared file is used for sharing information among a plurality of process, the plurality of processes including a daemon process and a plurality of pressure sub-processes; Obtaining a file pipeline corresponding to the shared file, andobtaining a shared memory according to the file pipeline, wherein the shared memory is a readable memory corresponding to the shared file; When the pressurizing sub-process generates a message, serializing the message to form a complete message in the shared file; The message is written to the shared file and the write index field of the shared memory is updated to send the message from the pressurizing child process to the daemon process through the shared memory.

Description

technical field [0001] The invention relates to the field of performance testing, in particular to a method for inter-process communication and related devices. Background technique [0002] The performance test platform stress test is a multi-process and multi-thread model. There are multiple stress processes on one stress machine. After the stress process is launched, it needs to be bound to the server port of the transmission control protocol (transmission control protocol, TCP). The number is passed to the pressure machine daemon process through the single-item inter-process communication between the pressure process and the pressure machine daemon process, and then passed to the control console. [0003] In the prior art, based on the open source stress testing platform NGrinder, java input and output streams are used as the daemon process and the stressing process, that is, a communication channel is established through the input stream of the parent process and the ou...
