I was selected as one of the Google Summer of Code students for Git in 2020, working to Implement Generation Number v2. You can find code on my repository.

- Reachability Queries - Reachability forms an important intermediate step in many graph algorithms, avoiding large worst-case penalties.
- Weeks 1, 2 - I worked on moving struct members generation and graph position out of commit, one of pre-requistes for generation number v2.
- Week 3 - I compared performance of metadata chunk and generation data chunk approaches with corrected commit dates with monotonic offsets
- Weeks 4, 5 - After the initial response to last week's performance numbers, it was time to dive deeper and investigate more possiblities. Meanwhile, I took off on a side quest to optimize commit graph write.
- Week 6 - After the exhaustive performance testing and much discussion, I worked on implementing corrected commit date with generation data chunk. Meanwhile, I found a performance regression in `commit-graph write --reachable --changed-paths`
- Week 7 - Implementing corrected commit date offsets was a trial of tests and debugging.
- Week 8 - Over the week, I wrapped up the failing tests for generation number v2 pull request and published it to the mailing list.
- Weeks 9, 10 - Over the last two weeks, I worked on handling mixed commit-graph chain and adding tests for the new features.
