FixCache is a github app implementation of FixCache with git commit history.

It provides code reviewers with information about probable bug introducing files updated in a pull request based on previous commits.

The prediction algorithm is executed over the commit history of the project and maintains a fixed-size cache of the most fault-prone files by keeping track of bug fix commits pushed to the configured tracked-branch of a repository. The bug fix commits are identified by the fix keywords provided in the configuration.

On pull requests, it fetches the cache and updates the pull requests with information about the files present in the cache if the pull request updates these files.

• it adds a label Fix Cache to the pull request.
• it adds a comment with the filenames present in the cache and the respective number of cache hits.
