Git third party

Tool for patching third-party libraries without need to fork them

This is a small zero-dependency utility that is an alternative to git-submodules and git-subtree. It stores only delta (changes) inside your tree

This tool is not oriented for highly concurrent modification of third-party tools by multiple users

Usage

# adding third-party repository
git-third-party add third-party/RustPython https://github.com/RustPython/RustPython.git a13b99642b0bc13ca89d01768a7ddbec18fe8219
# ^ git-third-party add <relative path> <repository url> <commit hash>

# now you can modify it as a regular repository, commit your changes

# save patches to push to your origin
git-third-party save third-party/RustPython
# ^ git-third-party save <relative path>

# update
git-third-party update third-party/RustPython
# ^ git-third-party update <relative path>

How it works?

It stores (at /.git-third-party/) a configuration that describes all third party repositories and patches. save command updates the patches, update command reapplies them

Directory .git-third-party must be controlled by git, while third-party repos should not

Best effort is done to keep patches deterministic and strip all metadata from them, which includes:

• git version
• commit hash (which depends on committer)
• ...
