static protected void perform_safe_login(stdClass $user)

Performs the login process safely.

If running in a PHPUnit environment, it sets the global user without regenerating the session ID (which causes errors in CLI) and avoids the redirect (which kills the test). In production, it performs the standard complete_user_login and redirect.

Parameters

stdClass $user

the Moodle user object

void
