Abstract

The embodiment of the invention discloses an inter-process communication method and a related device, which are used to solve the problem of unreliable communication content between parent and child processes in the prior art. The method in the embodiment of the present invention includes: creating a shared file in the press machine, the shared file is used for information sharing among multiple processes, and the multiple processes include a daemon process and multiple pressure sub-processes; obtaining the share the file pipeline corresponding to the file, and obtain a shared memory according to the file pipeline, and the shared memory is a readable memory corresponding to the shared file; when the pressure subprocess generates a message, sequence the message process to form a complete message in the shared file; write the message into the shared file, and update the write index field of the shared memory to write the message from the implementation through the shared memory Subprocess sends to the daemon process.

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...
