Subject: [PATCH v2 0/2] Sparse Index: diff and blame builtins
Date: Fri, 15 Oct 2021 21:20:33 +0000 [thread overview]
Message-ID: <pull.1050.v2.git.1634332835.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1050.git.1634232352.gitgitgadget@gmail.com>
This series is based on vd/sparse-reset. It integrates the sparse index with
git diff and git blame and includes:
1. tests added to t1092 and p2000 to establish the baseline functionality
of the commands
2. repository settings to enable the sparse index
The p2000 tests demonstrate a ~30% execution time reduction for 'git diff'
and a ~75% execution time reduction for 'git diff --staged' using a sparse
index. For 'git blame', the reduction time was ~60% for a file two levels
deep and ~30% for a file three levels deep.

Changes since V1
================
* Fix failing diff partially-staged test in
t1092-sparse-checkout-compatibility.sh, which was breaking in seen.
Thanks, Lessley
