Tian Yuchen's three-patch series cleans up repository config handling in environment.c. It simplifies the getters, clarifies their documentation and reorders the members of repo_config_values. The series intends no functional change.
Junio Hamano, replying to Patrick Steinhardt, said that even after a side discussion was dropped in early August, some topics still want to move things into repo_settings, or worse, repo_config_values. He asked whether this part of the code should be frozen until there is a plan to make repo_config_values() take an arbitrary repository.
He attached a draft patch titled "repo_config_values: freeze the structure for now". Its message describes configuration and settings per repository as an unfortunate mess. It says repo_config_values() cannot work on any repository instance other than the_repository, so moving more members into the structure is unwelcome.
The excerpts do not show whether Steinhardt or others have accepted the proposal, and the status of Tian Yuchen's series is unclear.
