With roughly 800 remotes all fetching into their own refs/remotes/$REMOTE/* island, the connectivity check[1] gets expensive for each fetch on systems which lack sufficient RAM to cache objects. To do a no-op fetch on one $REMOTE out of hundreds, hideRefs now allows the no-op fetch to take ~30 seconds instead of ~20 minutes on a noisy, RAM-constrained machine (localhost, so no network latency): git -c fetch.hideRefs=refs \ -c fetch.hideRefs='!refs/remotes/$REMOTE/' \ fetch $REMOTE [1] `git rev-list --objects --stdin --not --all --quiet --alternate-refs' Signed-off-by: Eric Wong <e@80x24.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
