[PATCH 2/2] config: respect includes in protected config

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Glen Choo <chooglen@xxxxxxxxxx>

Protected config is implemented by reading a fixed set of paths,
which ignores config [include]-s. Replace this implementation with a
call to config_with_options(), which handles [include]-s and saves us
from duplicating the logic of 1) identifying which paths to read and 2)
reading command line config.

As a result, git_configset_add_parameters() is unused, so remove it. It
was introduced alongside protected config in 5b3c650777 (config: learn
`git_protected_config()`, 2022-07-14) as a way to handle command line
config.
