Subject: [PATCH v3 09/10] submodule: merge repo_read_gitmodules and gitmodules_config
Date: Tue, 18 Jul 2017 12:05:26 -0700 [thread overview]
Message-ID: <20170718190527.78049-10-bmwill@google.com> (raw)
In-Reply-To: <20170718190527.78049-1-bmwill@google.com>
Since 69aba5329 (submodule: add repo_read_gitmodules) there have been
two ways to load a repository's .gitmodules file:
'repo_read_gitmodules()' is used if you have a repository object you are
working with or 'gitmodules_config()' if you are implicitly working with
'the_repository'. Merge the logic of these two functions to remove
duplicate code.
In addition, 'repo_read_gitmodules()' can segfault by passing in a NULL
pointer to 'git_config_from_file()' if a repository doesn't have a
worktree. Instead check for the existence of a worktree before
attempting to load the .gitmodules file.
