Subject: [PATCH v2 13/20] merge-ort: step 1 of tree writing -- record basenames, modes, and oids
Date: Mon,  2 Nov 2020 12:43:37 -0800	[thread overview]
Message-ID: <20201102204344.342633-14-newren@gmail.com> (raw)
In-Reply-To: <20201102204344.342633-1-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.
