Subject: [PATCH 1/2] config: use gitdir to get worktree config
Date: Tue, 23 May 2023 23:17:51 +0000 [thread overview]
Message-ID: <aead2fe1ce162949fb313a92fe960e5a64512f60.1684883872.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1536.git.1684883872.gitgitgadget@gmail.com>
From: Victoria Dye <vdye@github.com>
Update 'do_git_config_sequence()' to read the worktree config from
'config.worktree' in 'opts->git_dir' rather than the gitdir of
'the_repository'.
The worktree config is loaded from the path returned by
'git_pathdup("config.worktree")', the 'config.worktree' relative to the
gitdir of 'the_repository'. If loading the config for a submodule, this path
is incorrect, since 'the_repository' is the super project. Conversely,
'opts->git_dir' is the gitdir of the submodule being configured, so the
config file in that location should be read instead.
To ensure the use of 'opts->git_dir' is safe, require that 'opts->git_dir'
is set if-and-only-if 'opts->commondir' is set (rather than "only-if" as it
is now). In all current usage of 'config_options', these values are set
together, so the stricter check does not change any behavior.
Finally, add tests to 't3007-ls-files-recurse-submodules.sh' to demonstrate
the corrected config loading behavior. Note that behavior still isn't ideal
because 'extensions.worktreeConfig' in the super project controls whether or
not the worktree config is used in the submodule. This will be fixed in a
later patch.
