The “git-maintenance” command is a tool introduced in Git 2.24 to run various maintenance tasks that optimize and clean up Git repository data. It provides a unified interface for performing tasks related to maintenance and performance improvements.
By running the “git-maintenance” command, you can execute several maintenance tasks, including:
- Garbage collection: The “git-maintenance” command can run garbage collection (similar to “git gc”) to optimize the repository’s object database, reducing disk space usage and improving performance.
- Repacking: It can repack Git objects, which involves compressing and organizing them to improve efficiency and reduce the overall size of the repository.
- Pruning reflog: The reflog records reference updates in Git. The “git-maintenance” command can prune and optimize the reflog, making it more efficient and reducing its size.
- Expire unreachable objects: It can automatically remove objects that are no longer reachable from any branch or tag, freeing up disk space.
The “git-maintenance” command provides a unified and convenient way to run these maintenance tasks without the need to execute each task separately. It streamlines the maintenance process and allows for more efficient management of Git repositories.
git maintenance Command Examples
1. Register the current repository in the user’s list of repositories to daily have maintenance run:
# git maintenance register
2. Start running maintenance on the current repository:
# git maintenance start
3. Halt the background maintenance schedule for the current repository:
# git maintenance stop
4. Remove the current repository from the user’s maintenance repository list:
# git maintenance unregister
5. Run a specific maintenance task on the current repository:
# git maintenance run --task=[commit-graph|gc|incremental-repack|loose-objects|pack-refs|prefetch]
