The commit-graph feature is starting to stabilize. Based on what is in master right now, we have: Git 2.18: * Ability to write commit-graph (requires user interaction). * Commit parsing is faster when commit-graph exists. * Must have core.commitGraph true to use. Git 2.19: * Ability to write commit-graph on GC with gc.writeCommitGraph. * Generation numbers written in commit-graph * A few reachability algorithms make use of generation numbers. (queued for) master: * The test suite passes with GIT_TEST_COMMIT_GRAPH=1 * 'git commit-graph write' has progress indicators. * The commit-graph is automatically disabled when grafts or replace-objects exist. There are some other things coming that are in review (like 'git log --graph' speedups), but it is probably time to consider enabling the commit-graph by default. This series does that. For timing, I'm happy to leave this queued for a merge after the Git 2.20 release. There are enough things in master to justify not enabling this by default until that goes out and more people use it. PATCH 3/3 is rather simple, and is the obvious thing to do to achieve enabling these config values by default. PATCH 1/3 is a required change to make the test suite work with this change. This change isn't needed with GIT_TEST_COMMIT_GRAPH=1 because the commit-graph is up-to-date for these 'git gc' calls, so no progress is output. PATCH 2/3 is also a necessary evil, since we already had to disable GIT_TEST_COMMIT_GRAPH for some tests, we now also need to turn off core.commitGraph.
