From: Elijah Newren <newren@gmail.com> To: git@vger.kernel.org Cc: Elijah Newren <newren@gmail.com> 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.
