From bf48e5acdbf25a98fd142d9c90157c10b427119a Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Wed, 14 Jul 2021 13:12:36 +0000 Subject: [PATCH] status: skip sparse-checkout percentage with sparse-index 'git status' began reporting a percentage of populated paths when sparse-checkout is enabled in 051df3cf (wt-status: show sparse checkout status as well, 2020-07-18). This percentage is incorrect when the index has sparse directories. It would also be expensive to calculate as we would need to parse trees to count the total number of possible paths. Avoid the expensive computation by simplifying the output to only report that a sparse checkout exists, without the percentage. This change is the reason we use 'git status --porcelain=v2' in t1092-sparse-checkout-compatibility.sh. We don't want to ensure that this message is equal across both modes, but instead just the important information about staged, modified, and untracked files are compared.
