What is in that .git directory?
By random chance I ended up in the git internals doc^1 today, also lovely refered to as plumbing and porcelain. It's a fantastic read, very well explained. I wish all doc was written with such explicit care to be understood. It reads like a good friend is trying to explain you something.<p>What got me into that was a 51Gb ".pack" file that I wanted to understand. If you wonder about that, they're pack files, and what that "delta compression" message when you commit is about^2. The 51Gb file though I don't have an explanation for as of yet, I'm guessing something terrible happened before I joined, and people didn't find the courage to forego the history just yet. But at least I got an entertaining read out of it.<p>^1: <a href="https://git-scm.com/book/en/v2/Git-Internals-Plumbing-and-Porcelain" rel="nofollow noreferrer">https://git-scm.com/book/en/v2/Git-Internals-Plumbing-and-Po...</a><p>^2: <a href="https://git-scm.com/book/en/v2/Git-Internals-Packfiles" rel="nofollow noreferrer">https://git-scm.com/book/en/v2/Git-Internals-Packfiles</a>
