![]() After the developer makes and tests their changes, they “commit” them, saving the revised code to the repository. At the same time, the original file in the repository is locked so that no one else can check out that piece of code and inadvertently overwrite the current developer’s changes. Developers “check out” a file when they want to make code revisions and receive a copy of that file in their local environment. The heart of the source code management process is the code repository, a centralized server that stores all of an organization’s code as well as the source code management system that tracks code changes for various development projects.Ĭopies of source code are stored as individual files. In the sections that follow, we’ll take a closer look at how source code management works, what benefits it brings to software development, and which best practices to follow to get the most out of the process. Developers are alerted to any conflicts so they can address them before they are merged into the source code and potentially compromise the application. Source code management solves these problems by tracking each developer’s changes, highlighting conflicts and preventing code overwriting. And when it worked, this method left no record of all the changes made over the course of a project - if a change resulted in a bug, there was no way to trace where it originated or determine how to fix it. ![]() That said, it was hardly a foolproof process. ![]() Each time a developer started working on a file, they would have to let all the others know to ensure no one else was working on it simultaneously. And with each developer working on their respective feature, they could unknowingly make conflicting code changes - or one developer’s saved edits could overwrite the other developer’s changes.īefore the adoption of source code management, there were few safeguards to prevent these scenarios. Source code management is important because multiple developers typically work in a shared codebase. Keeping a running history of the changes made to a codebase helps programmers, developers and testers ensure that they’re always working with accurate and up-to-date code and helps resolve conflicts when merging code from multiple sources. Source code management is the practice of tracking modifications to source code.
