Yes, it was definitely worth it, for multiple reasons: - I'm a lot more comfortable with Python than I am with shell scripting - The Python+libgit2 approach _absolutely_ saved time. Being able to iterate through commits in 4-ish hours vs 24 hours for a complete run was huge, and yes, I did a lot of partial runs to test how the process was going. - Yes, the code rewriting portion ended up as the bulk of the time. I could do a no-op iteration of the commit history in about 30 minutes, and the final processing was about 4.5 hours. If I ever needed to do this again, yes, I'd use basically the same approach, just with the advantage of applying the knowledge I learned right away.
