commit aaef9a2519d81c016bc1f58272121ed908fbff10 Author: teor <teor@torproject.org> Date: Thu Nov 7 10:44:10 2019 +1000 relay: Stop failing on startup when the relay module is disabled When the relay module is disabled, make "ClientOnly 1" and "DirCache 0" by default. (But keep "ClientOnly 0" and "DirCache 1" as the defaults for the unit tests.) And run "make autostyle".
