A Django application to browse a Git repository and build Web applications on top of it.

GitStorage is:

• A Django storage to browse the contents of the repository (what you see in your working copy) from a bare repository (without a working copy);
• Models to enrich Git objects, namely add metadata to blobs and allow access to trees;
• Mixin views to combine with class-based views to browse the repository and add or remove objects. on top of the repository;
• Management commands.

GitStorage is built on top of PyGit2 and libgit2, it does not call Git from the command line.

The Django storage supports most of the storage API: open, save, exists, listdir... missing features include mtime, ctime and atime since Git doesn't directly store those values.

The storage is limited just as any Git repository. It is designed for a single writer and many readers. Concurrent writing is not even tested. No effort was made to optimise read access either. Your mileage may vary.

The storage is an interesting proof-of-concept but even the rest of GitStorage loads Git objects directly.

Add metadata to the blob, only mimetype for now.

Only admin users are allowed by default. Share access to a tree and its blobs (but not its subtrees) to a regular user.

These views are designed as the foundation of class-based views like TemplateView and FormView, and your own business logic.

The main view that dispatches to a view dedicated to each Git object type (namely blob and tree).

Not actually a mixin since it is functional but the dedicated views are mixins (see below).

Default view for a tree, lists its contents.

Default view for a blob, displays its information.

Preview the current blob in the browser if possible, download it otherwise.

Force download the current blob.

Delete the current blob.

Upload a new file to the current tree (as a blob).

List of current tree permissions and removing the selected ones.

Share access to the current tree to a user by adding a tree permission.

Browse the repository to compute metadata for each blob not known yet.

To call after pushing new commits to the repository, ideally from a Git hook.

Cleaning up of metadata for orphan blobs is not handled.

A minimal Django project is shipped to run the test suite. Try make coverage (100% at the time of this writing).
