Commit0433ad1(clone: run check_everything_connected, 2013-03-25) added the same connectivity check to clone that we use for fetching. The intent was to provide enough safety checks that "git clone git://..." could be counted on to detect bit errors and other repo corruption, and not silently propagate them to the clone. For local clones, this turns out to be a bad idea, for two reasons: 1. Local clones use hard linking (or even shared object stores), and so complete far more quickly. The time spent on the connectivity check is therefore proportionally much more painful. 2. Local clones do not actually meet our safety guarantee anyway. The connectivity check makes sure we have all of the objects we claim to, but it does not check for bit errors. We will notice bit errors in commits and trees, but we do not load blob objects at all. Whereas over the pack transport, we actually recompute the sha1 of each object in the incoming packfile; bit errors change the sha1 of the object, which is then caught by the connectivity check. This patch drops the connectivity check in the local case. Note that we have to revert the changes from0433ad1to t5710, as we no longer notice the corruption during clone. We could go a step further and provide a "verify even local clones" option, but it is probably not worthwhile. You can already spell that as "cd foo.git && git fsck && git clone ." or as "git clone --no-local foo.git". Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
