Precompute and store information necessary for ancestry traversal
in a separate file to optimize graph walking.
Ready???
It seems that this topic is getting there.
I think this patch is ready to go, barring the edit of "--additive" to
"--append" in the final commit message and squashing following diff into
"commit-graph: implement git commit-graph read":

If you prefer that I re-roll with those changes, I can send a v8.
I'm currently working on new series based on this feature:
* [1] Lazy-load trees when reading commit-graph (ds/lazy-load-trees)
* [2] Compute and consume generation numbers
* Move commit-graph.c globals to the_repository
* Implement 'fsck' functionality for the commit-graph file
* Integrate 'commit-graph write' into 'gc --auto'
I would also like to open the feature to other contributors, especially
for others who can contribute performance improvements using generation
numbers. We had a very valuable discussion on the list [2], and I look
forward to more collaborations like that.
Thanks,
