Subject: [PATCH 0/7] Sparse Index: integrate with reset
Date: Thu, 30 Sep 2021 14:50:54 +0000 [thread overview]
Message-ID: <pull.1048.git.1633013461.gitgitgadget@gmail.com> (raw)
This series integrates the sparse index with git reset and provides
miscellaneous fixes and improvements to the command in sparse checkouts.
This includes:
1. tests added to t1092 and p2000 to establish the baseline functionality
of the command
2. repository settings to enable the sparse index with ensure_full_index
guarding any code paths that break tests without other compatibility
updates.
3. modifications to remove or reduce the scope in which ensure_full_index
must be called.
The sparse index updates are predicated on a fix originating from the
microsoft/git fork [1], correcting how git reset --mixed handles resetting
entries outside the sparse checkout definition. Additionally, a performance
"bug" in next_cache_entry with sparse index is corrected, preventing
repeatedly looping over already-searched entries.
The p2000 tests demonstrate an overall ~70% execution time reduction across
all tested usages of git reset using a sparse index:
