Subject: [Outreachy PATCH v4 1/3] environment: stop storing `core.attributesFile` globally
Date: Sat, 24 Jan 2026 12:55:04 +0100 [thread overview]
Message-ID: <d28850bcdb5677ad0c81cf4bfa51ae1c056aabd3.1769252118.git.belkid98@gmail.com> (raw)
In-Reply-To: <cover.1769252118.git.belkid98@gmail.com>
The `core.attributeFile` config value is parsed in
git_default_core_config(), loaded eagerly and stored in the global
variable `git_attributes_file`. Storing this value in a global variable
can lead to it being overwritten by another repository when more than one
Git repository run in the same Git process.
Create a new struct `repo_config_values` to hold this value and
other repository dependent values parsed by `git_default_config()`.
For now the value can be accessed via the_repository in
`git_default_config()`.
This will ensure the current behaviour remains the same while also
enabling the libification of Git.
It is important to note that `git_default_config()` is a wrapper to other
`git_default_*_config()` functions such as `git_default_core_config()`.
Therefore to access and modify this global variable,
the change has to be made `git_default_core_config()`.
