Thank you, that was much easier to read, and I've got my prototype working now. I also found this site to be quite helpful:On Tue, Mar 20, 2018 at 4:43 PM, Luke Robison <robison@xxxxxxxxxxxxxxxx> wrote:Is there any documentation of the contents of the binary delta datain a packfile, and how to interpret them? I found https://github.com/git/git/blob/master/Documentation/technical/pack-format.txt documenting the packfile itself, but the "compressed delta data" seems largely undocumented. The source code of https://github.com/git/git/blob/master/diff-delta.c is pretty dense.The output is consumed by patch_delta() in patch-delta.c if I'm not mistaken. This function is less than 100 lines, probably much easier to see the delta format.
