From: Derrick Stolee <dstolee@xxxxxxxxxxxxx> The commit-graph feature began with a long list of planned benefits, most of which are now complete. The future work section has only a few items left. As for making more algorithms aware of generation numbers, some are only waiting for generation number v2 to ensure the performance matches the existing behavior using commit date. It is unlikely that we will ever send a commit-graph file as part of the protocol, since we would need to verify the data, and that is as expensive as writing a commit-graph from scratch. If we want to start trusting remote content, then that item can be investigated again. While there is more work to be done on the feature, having a section of the docs devoted to a TODO list is wasteful and hard to keep up-to-date.

The commit-graph will not be read or written when shallow commits are present. -Future Work ------------ - -- After computing and storing generation numbers, we must make graph - walks aware of generation numbers to gain the performance benefits they - enable. This will mostly be accomplished by swapping a commit-date-ordered - priority queue with one ordered by generation number. The following - operations are important candidates: - - - 'log --topo-order' - - 'tag --merged' - -- A server could provide a commit-graph file as part of the network protocol - to avoid extra calculations by clients. This feature is only of benefit if - the user is willing to trust the file, because verifying the file is correct - is as hard as computing it from scratch. - Related Links ------------- [0] https://bugs.chromium.org/p/git/issues/detail?id=8 -- gitgitgadget
