treeherder

Treeherder is a web-based tool used for managing code repositories and tracking bug reports, primarily within the Mozilla community. It serves as a central hub for developers to submit code changes, review them, and address issues found in the software. The system integrates with version control systems like Mercurial and Git, allowing developers to push their code to specific branches.

The core functionality of Treeherder revolves around its ability to build and test code changes automatically. When a developer submits a new patch or commit, Treeherder triggers a build process across various operating systems and configurations. These automated tests then verify the integrity of the code and identify any potential regressions or bugs. The results of these builds and tests are displayed prominently, providing immediate feedback to the developer.

Treeherder also plays a crucial role in the bug triaging and resolution process. Bug reports, often submitted through a separate system like Bugzilla, can be linked to specific code commits. This allows developers and reviewers to easily track which changes are intended to fix which bugs. The interface provides a clear overview of the status of different code branches and the associated bugs, aiding in the efficient management of the development lifecycle. It is designed to facilitate collaboration and ensure code quality through continuous integration and automated testing.
