Embodiment Construction

[0037] For applications where java calls lua-related script logic, how to simultaneously sample the call stacks of java and lua during the running of the program, and how to stitch and process the call stack data accurately has always been an urgent problem in the industry. Among the existing technical solutions and technical tools in the industry, most of them can only perform performance analysis for a single language. For example, if you use TProfiler, an official performance tuning analysis tool provided by Ali, to analyze the performance of an application that calls lua-related script logic from java, you can only see relevant performance analysis data such as the java program call stack, and the relevant performance analysis data such as the lua function call stack is missing. . However, program developers hope to see complete results including all performance analysis data of java and lua as a whole.

[0038] Therefore, the embodiment of the present disclosure provides a...

Abstract

The invention discloses a method and a device for acquiring a java-lua hybrid method call stack. The method comprises the following steps: firstly, acquiring a java method call stack of a target application program; the method comprises the following steps: acquiring a Java method call stack, acquiring a LuaJ virtual machine, acquiring lua call stack data through the LuaJ virtual machine, performing data stitching processing on the acquired java method call stack according to a specific java call lua script stack frame position and the lua method call stack, and determining a more complete method call stack of a java-lua application program of the target based on the stitched method call stack. According to the method, more comprehensive performance analysis data can be obtained, and the performance analysis accuracy of the application program can be improved.

Description

technical field [0001] The invention relates to the field of performance analysis, in particular to a method, device, equipment and storage medium for acquiring java-lua application program performance analysis data. Background technique [0002] Performance analysis (also known as profiling) is an analysis method that studies program behavior by means of collecting program runtime information, and is a dynamic program analysis method. Performance analysis measures such as the space or time complexity of the program, the usage of specific instructions, the frequency of function calls, and the running time. The purpose of performance analysis is to determine which part of the program should be optimized to improve the program's speed or memory usage efficiency. Performance analysis can be performed on a program's source code or executable file. Typically this is done using a tool called a profiler. Performance analysis tools will use many different techniques, which may be...
