Subject: [PATCH v5 04/10] merge-ort: capture and print ll-merge warnings in our preferred fashion
Date: Wed, 02 Feb 2022 02:37:31 +0000 [thread overview]
Message-ID: <d7a1f4e1f9f5bdbd2ebff1586af73d2ea1a0319e.1643769457.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1103.v5.git.1643769457.gitgitgadget@gmail.com>
From: Elijah Newren <newren@gmail.com>
Instead of immediately printing ll-merge warnings to stderr, we save
them in our output strbuf. Besides allowing us to move these warnings
to a special file for --remerge-diff, this has two other benefits for
regular merges done by merge-ort:
* The deferral of messages ensures we can print all messages about
any given path together (merge-recursive was known to sometimes
intersperse messages about other paths, particularly when renames
were involved).
* The deferral of messages means we can avoid printing spurious
conflict messages when we just end up aborting due to local user
modifications in the way. (In contrast to merge-recursive.c which
prematurely checks for local modifications in the way via
unpack_trees() and gets the check wrong both in terms of false
positives and false negatives relative to renames, merge-ort does
not perform the local modifications in the way check until the
checkout() step after the full merge has been computed.)
