Subject: [PATCH v2 05/20] merge-ort: add an err() function similar to one from merge-recursive
Date: Fri, 04 Dec 2020 20:47:55 +0000 [thread overview]
Message-ID: <6c4c0c15b3d1283d817149181cdf88903926a52b.1607114890.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.923.v2.git.git.1607114890.gitgitgadget@gmail.com>
From: Elijah Newren <newren@gmail.com>
Various places in merge-recursive used an err() function when it hit
some kind of unrecoverable error. That code was from the reusable bits
of merge-recursive.c that we liked, such as merge_3way, writing object
files to the object store, reading blobs from the object store, etc. So
create a similar function to allow us to port that code over, and use it
for when we detect problems returned from collect_merge_info()'s
traverse_trees() call, which we will be adding next.
