  "message": "stash: avoid sparse-index expansion for in-cone paths\n\n`git stash push -- \u003cpathspec\u003e` expands a sparse index before checking\nwhether the pathspec matches any tracked paths. This is unnecessary\nwhen the pathspec is wholly inside the sparse-checkout cone and makes\na path-limited stash proportional to the size of the full index.\n\nUse `pathspec_needs_expanded_index()` to expand only when a pathspec\ncan match part of a sparse-directory entry, as `git rm` and `git\nreset` already do. Keep the full-index behavior for pathspecs that\nneed it.\n\nAdd compatibility coverage for literal, prefixed, wildcard, file,\nmultiple, staged, and missing pathspecs. Add the corresponding\npath-limited stash case to p2000.\n\nOn a cone-mode repository with 349,525 tracked paths and 49 sparse\nindex entries, the best of three runs changed from 18.87s to 0.06s.\nTrace2 reported four index expansions before this change and none\nafter it.\n\nSigned-off-by: Ted Nyman \u003ctnyman@openai.com\u003e\nReviewed-by: Taylor Blau \u003cttaylorr@openai.com\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
