Magento Diffchecker

Tool written in Go that checks Magento rewrites.

Features

This program allows to check if what has been modified in a patch file has been rewritten in a Magento 1 project. It works for official Magento security patches and patches manually generated with Git also.

Especially useful for a migration project since it's possible to generate a list of which files must be absolutely checked. Two kinds of objects are currently checked: classes and templates. It's working for both Magento CE and Magento EE, but community modules are not yet supported.

⚠️ Disclaimer ⚠️

Even if the list generated by this tool is a good entry point for a migration work, it's definitely not exhaustive because of the Magento architecture. Therefore, a Magento expertise is still needed for a migration process.

Usage

Two arguments are mandatory and can be passed either as parameters or as environment variables.

• patch: absolute or relative path to the Magento/Git patch to check.
• project: absolute or relative path to the project directory against whom the patch will be checked.
