git-cmp

Simple git repository comparison tool based on pygit2 (written in Python).

Enables to compare two repositories on selected level:

• References - checks if repositories contain the same references, no matter where they are pointing to
• Commits - checks if repository commit structure is the same, no matter on the contents of individual commits
• Trees - checks if each corresponding commit has same file structure inside, but does not care about contents of these files
• Blobs - behaves like a regular diff, also compares contents of the files

Reason

This application is developed for automated checks of Git repository structure against a given one. Originally for BI-GIT course on Faculty of Information Technology, Czech Technical University in Prague, Czech Republic.

Usage

./gitcmp.py <original_repository> <new_repository>

Couple switches are supported:

• --level (-l) selects the level of comparison: ref, commit, tree, blob
• --pedantic (-p) forces a mutual check (new must not contain anything in excess)
• --author (-a) also check name and email of the commit author (level must be greater than ref)
• -v print a lot more information (spoilers)
