Subject: [PATCH 1/5] config: relax requirements on multi-value return
Date: Tue, 27 Sep 2022 14:08:27 +0000 [thread overview]
Message-ID: <b2558a737f31465b38ad361a412d923ef186a38a.1664287711.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1369.git.1664287711.gitgitgadget@gmail.com>
From: Derrick Stolee <derrickstolee@github.com>
The git_configset_get_value() method has an assert() statement
guaranteeing that the result from git_configset_get_value_multi() is
either NULL or has at least one element. We want to change that return
to provide an empty list instead of a NULL list, so change the earlier
'return 1' condition to care about a NULL or empty list.
