Process variable storage method and device

Abstract

The invention discloses a process variable storage method and device, and relates to the field of communication. The system analysis expenditure is reduced. The method adopts the following scheme that a middle frame is allocated for a target program, wherein the target program comprises a tested function; calling information when a tested function is called is obtained through executing an inlet pile function, the calling information is stored into a storage region, and in addition, a storage address of the calling information in the storage region is stored in the middle frame; return information when the tested function is called is obtained through executing an outlet pile function, in addition, the return information is stored into the storage region according to the storage address of the calling information stored in the middle frame in the storage region, and the calling information and the return information are stored in two sub units of the same storage unit in the storage region. The method and the device provided by the invention are used in the process variable storage process.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for storing process variables. Background technique [0002] With the continuous development of computer technology, software dynamic testing becomes more and more important. In software dynamic testing, instrumentation technology is a basic testing method. The instrumentation technology mainly inserts corresponding statements into the program under test to obtain the required information during program execution, so that system analysis and performance collection can be performed based on the obtained information. For example, if figure 1 As shown, in the process of calling function A (the function under test) by a certain task, after inserting the entry and exit of function A, by analyzing the stack corresponding to the task, the function A collected when executing the stub function A1 can be obtained. Parameters at the time of calling, time t1 and other related ...

AI Technical Summary

Problems solved by technology

[0004] There are at least the following problems in the prior art: since system analysis and performance collection are based on all corresponding information pairs (namely M1 and M2) collected at the entry and exit of the function during a single call, and if If multiple tasks call the same function under test in parallel or nestedly, when the function is called once, the information collected at the entry and exit of the function is likely to be recorded in the storage area far away. location, so that when performing offline analysis, it takes quite complex analysis to obtain all the collected information pairs with corresponding relationships, which increases the overhead of system analysis
