Abstract

The present application provides a code processing method, device, device and storage medium. By processing the source code to be processed, an abstract syntax tree corresponding to the source code is constructed, and then the source code is analyzed based on the abstract syntax tree to obtain the source code. The control flow analysis results of the abstract syntax tree are released, and the memory space occupied by the abstract syntax tree is released. The control flow analysis results include: the index information of the abstract syntax tree with common parts, positioning parts and verification parts. Finally, the source code is analyzed based on the control flow analysis results of the source code. Defect analysis is performed to obtain the defect detection results of the source code. In this technical solution, after the control flow analysis of the source code based on the source code of the abstract syntax tree, the memory space occupied by the abstract syntax tree is released, which can reduce the memory usage rate, and at the same time, use the obtained abstract syntax tree index information to ensure The detection accuracy of the source code is not affected, and the problem of large memory usage in the prior art is solved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a code processing method, device, equipment and storage medium. Background technique [0002] Static code analysis technology refers to scanning the program code through lexical analysis, syntax analysis, control flow, data flow analysis and other technologies without running the program code, and verifying whether the code meets the requirements of standardization, security, reliability, and reliability. A code analysis technique for indicators such as maintainability. [0003] In the prior art, the main principle of the code analysis method is: firstly, the code is processed to construct an abstract syntax tree; secondly, the information of the abstract syntax tree is used for control flow analysis; , value dependency analysis and other superior analysis methods, and finally aiming at specific problems, comprehensive analysis methods at various levels, to deter...
