Git Internals - Graphs, Hashes, and Compression

Dive into the inner workings of Git in this 58-minute conference talk from EuroPython 2013. Explore key concepts such as staging areas, the Git directory structure, and hash functions. Understand how Git handles empty files, implements delta storage, and manages compressed files. Learn about blobs, tree hashes, and commit hashes, and how they contribute to Git's revision history. Discover the intricacies of branching, merging, and rebasing, including how Git handles random changes and conflicts. Gain insights into advanced Git commands like git log, git branch, git merge, git reflog, git revlist, and git rebase. By the end of this talk, acquire a deeper understanding of Git's internal mechanisms and how they enable efficient version control.
