From 0a8e3036a304d99de24432d65a3d3920dd6e2e46 Mon Sep 17 00:00:00 2001 From: Nika Layzell Date: Sun, 24 Nov 2019 20:25:49 +0000 Subject: reset: parse rev as tree-ish in patch mode Since 2f328c3d ("reset $sha1 $pathspec: require $sha1 only to be treeish", 2013-01-14), we allowed "git reset $object -- $path" to reset individual paths that match the pathspec to take the blob from a tree object, not necessarily a commit, while the form to reset the tip of the current branch to some other commit still must be given a commit. Like resetting with paths, "git reset --patch" does not update HEAD, and need not require a commit. The path-filtered form, "git reset --patch $object -- $pathspec", has accepted a tree-ish since 2f328c3d. "git reset --patch" is documented as accepting a since bf44142f ("reset: update documentation to require only tree-ish with paths", 2013-01-16). Documentation changes are not required. Loosen the restriction that requires a commit for the unfiltered "git reset --patch $object".
