#
#  Configuration of code ownership and review approvals for the angular/angular repo.
#
#  More info: https://docs.pullapprove.com/
#
# =========================================================
#  General rules / philosophy
# =========================================================
#
#  - We trust that people do the right thing and won't approve changes they don't feel confident reviewing
#  - We enforce that only approved PRs are merged ensuring that unreviewed code isn't accidentally merged
#  - We distribute approval rights as much as possible to help us scale better
#  - Groups have one or two global approvers groups as fallbacks:
#    - @angular/fw-global-approvers: for approving minor changes, large-scale refactorings, and emergency situations.
#    - @angular/fw-global-approvers-for-docs-only-changes: for approving minor documentation-only changes that don't require engineering review
#  - A small number of file groups have very limited number of reviewers because incorrect changes to the files they guard would have serious consequences (e.g. security, public api)
#
#  Configuration nuances:
#
#  - This configuration works in conjunction with the protected branch settings that require all changes to be made via pull requests with at least one approval.
#  - This approval can come from an appropriate codeowner, or any repo collaborator (person with write access) if the PR is authored by a codeowner.
#  - All groups whose pullapprove rules are matched will be required for overall approval.
#
#  NOTE:
#    In the case of emergency, the repo administrators which include the current angular caretaker
#    can bypass this reviewer approval requirement, this is expected as a last resort and to be
#    done exceedingly sparingly.
