Subject: [PATCH v4 01/10] config: initialize opts structure in repo_read_config()
Date: Mon, 15 Apr 2019 13:39:42 -0700 (PDT)
Message-ID: <f6653f1c5914d4ed0edee87a56277a35625135ca.1555360780.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.169.v4.git.gitgitgadget@gmail.com>

From: Jeff Hostetler <jeffhost@microsoft.com>

Initialize opts structure in repo_read_config().

This change fixes a crash in later commit after a new field is added
to the structure.

In commit 3b256228a66f8587661481ef3e08259864f3ba2a, repo_read_config()
was added.  It only initializes 3 fields in the opts structure.  It is
passed to config_with_options() and then to do_git_config_sequence().
However, do_git_config_sequence() drops the opts on the floor and calls
git_config_from_file() rather than git_config_from_file_with_options(),
so that may be why this hasn't been a problem in the past.
