Revision b9063afda17a2aa6310423c9f7b776c41f753091 authored by Carlo Marcelo Arenas Belón on 13 May 2022, 01:00:19 UTC, committed by Junio C Hamano on 13 May 2022, 01:12:23 UTC
Add a support library that provides one function that can be used to run a "scriplet" of commands through sudo and that helps invoking sudo in the slightly awkward way that is required to ensure it doesn't block the call (if shell was allowed as tested in the prerequisite) and it doesn't run the command through a different shell than the one we intended. Add additional negative tests as suggested by Junio and that use a new workspace that is owned by root. Document a regression that was introduced by previous commits where root won't be able anymore to access directories they own unless SUDO_UID is removed from their environment. The tests document additional ways that this new restriction could be worked around and the documentation explains why it might be instead considered a feature, but a "fix" is planned for a future change.
