From 879321eb0bec25779386445d65242452825155be Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Thu, 21 Nov 2019 22:04:40 +0000 Subject: sparse-checkout: add 'cone' mode The sparse-checkout feature can have quadratic performance as the number of patterns and number of entries in the index grow. If there are 1,000 patterns and 1,000,000 entries, this time can be very significant. Create a new Boolean config option, core.sparseCheckoutCone, to indicate that we expect the sparse-checkout file to contain a more limited set of patterns. This is a separate config setting from core.sparseCheckout to avoid breaking older clients by introducing a tri-state option. The config option does nothing right now, but will be expanded upon in a later commit.
