Process communication method and process communication system

Abstract

The invention discloses a process communication method. The process communication method includes steps of distributing memory spaces according to process communication requests; storing communication data into the memory spaces; writing logic addresses of the memory spaces into a message queue; reading the logic addresses in the message queue to access the communication data. The process communication method and a process communication system have the advantages that the memory spaces used for storing the communication data are distributed when the process communication requests are received, and accordingly storage spaces for the communication data are not required to be divided in advance; the logic addresses of the memory spaces are written into the message queue and can be read to access the communication data, so that the logic addresses in the message queue can be read one by one to orderly access the communication data in data access processes under the effect of the message queue, the communication data do not need to be copied in communication procedures among the multiple processes, and the data sharing flexibility is greatly improved.

Description

【Technical field】 [0001] The invention relates to network application technology, in particular to a process communication method and system. 【Background technique】 [0002] With the gradual increase of various applications in the network server and the improvement of performance, the communication between processes is becoming more and more frequent, and the amount of data exchanged in the communication process is also increasing, which makes the communication between processes have many defects. Traditional process communication includes Apache's process communication model and memory sharing process communication method. Apache is a widely used web server software. It maintains a process pool to achieve data interaction between the main process and multiple processes in the process pool. For example, the processes in the process pool are used to execute programs in the web server, that is, CGI (Common Gateway Interface, based on the input of the browser, the program runn...

Problems solved by technology

However, the pre-delineated shared memory area is static, and the actual data length during process communication cannot be expected. Often there will be insufficient shared memory area, or the waste of space, and there are also defects of inflexibility.
