Subject: [PATCH v3 16/18] unpack-trees: provide warnings on sparse updates for unmerged paths too
Date: Fri, 27 Mar 2020 00:48:59 +0000 [thread overview]
Message-ID: <5d9e8a9d27e13670b56fe05dc36c066ec766b390.1585270142.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.726.v3.git.git.1585270142.gitgitgadget@gmail.com>
From: Elijah Newren <newren@gmail.com>
When sparse-checkout runs to update the list of sparsity patterns, it
gives warnings if it can't remove paths from the working tree because
those files have dirty changes. Add a similar warning for unmerged
paths as well.
