The commit-graph feature is now on by default, and is being written during 'git gc' by default. Typically, Git only writes a commit-graph when a 'git gc --auto' command passes the gc.auto setting to actualy do work. This means that a commit-graph will typically fall behind the commits that are being used every day. To stay updated with the latest commits, add a step to 'git fetch' to write a commit-graph after fetching new objects. The fetch.writeCommitGraph config setting enables writing a split commit-graph, so on average the cost of writing this file is very small. Occasionally, the commit-graph chain will collapse to a single level, and this could be slow for very large repos. For additional use, adjust the default to be true when feature.experimental is enabled. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
