Subject: [PATCH v2 10/11] repo_get_merge_bases_many(): pass on errors from `merge_bases_many()`
Date: Thu, 22 Feb 2024 13:21:49 +0000 [thread overview]
Message-ID: <602a7383f726c14bf7941653c2825b4c345247c8.1708608110.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1657.v2.git.1708608110.gitgitgadget@gmail.com>
From: Johannes Schindelin <johannes.schindelin@gmx.de>
The `merge_bases_many()` function was just taught to indicate parsing
errors, and now the `repo_get_merge_bases_many()` function is aware of
that, too.
Naturally, there are a lot of callers that need to be adjusted now, too.
Next stop: `repo_get_merge_bases_dirty()`.
