A git-based code line life cycle tracing method and electronic device

Abstract

The invention discloses a Git-based code line life cycle tracing method and an electronic device, which extracts the information of each commit in the Git warehouse; according to the ID of the commit and the ID of the corresponding parent commit, a directed acyclic composed of commits is established Graph, traverse the directed acyclic graph in breadth-first order, track, extract and record the change history information of the code file line according to the code change content of the commit; for a line of code to be queried in a file in a commit, according to the code file line The change history information record of the row to obtain the commit information of the generation, displacement or demise of the code to be queried. The present invention traces the code life cycle data at the line granularity, including the generation point, displacement point, and death point of the code line; it can trace back the complete change history of the code line on multiple branches; given any file in any commit snapshot Any row can directly return its full lifetime data.

Description

technical field [0001] The invention relates to the field of software code change history tracing, in particular to a Git-based code line life cycle tracing method and electronic device. Background technique [0002] Version control is an important practice method in software development. Software projects use a version control system to record the history of software code changes, including the developer, time, and content of each change. [0003] Git is currently the most popular version control system. Git uses commit to record every code change. Each commit has a unique ID. There is a parent-child relationship between commits, indicating the logical sequence of commits. These parent-child relationships will The commit links in a repository become a directed acyclic graph. [0004] The format of the code changes in Git is the same as the unified format of the diff tool in the Linux system. [0005] Version control systems such as Git use commit as the basic unit to trac...

Problems solved by technology

[0005] When a version control system such as Git records code changes, it uses commit as the basic unit to trace the change history of the code. The commit also includes the changed code file and the changed line in the file. When a developer or researcher wants to change the code line Life cycle, that is, the process of a line of code from appearing in the code base to disappearing. When conducting research, relevant data cannot be obtained directly, that is, the life cycle data of the code line in the Git repository cannot be obtained.
