Subject: [PATCH 13/20] merge-ort: step 1 of tree writing -- record basenames, modes, and oids
Date: Sun, 29 Nov 2020 07:43:16 +0000	[thread overview]
Message-ID: <242c3cab1349905af9b645a0a3e213edd49846ad.1606635803.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.923.git.git.1606635803.gitgitgadget@gmail.com>

From: Elijah Newren <newren@gmail.com>

As a step towards transforming the processed path->conflict_info entries
into an actual tree object, start recording basenames, modes, and oids
in a dir_metadata structure.  Subsequent commits will make use of this
to actually write a tree.
