A developer built a simplified version control system from scratch to understand git's internals. The implementation uses SHA-256 hashing (instead of git's SHA-1) and zstd compression (instead of zlib) to store file objects, tree structures, and commits. The project demonstrates how git works as a content-addressable file store, with commits referencing tree objects that contain file hashes. Key features include recursive directory traversal, object compression/decompression, commit generation with parent tracking, and checkout functionality. The hardest part was parsing the custom object formats, which could be improved by using structured formats like JSON or YAML.

I made my own git

<p>What is the reasoning behind choosing SHA256, aside from it being newer? As far as I understand, SHA1 is faster. Although it is not as secure, you state that it is not a concern.</p>


<p>Nice, but its not working as of now.</p>
