[tor/master] relay: Don't log at warn level when we find an address

commit a576f37cfeff9f6b0a13a9475b5eed424ee44db9 Author: David Goulet <dgoulet(a)torproject.org> Date: Mon Jul 20 10:58:54 2020 -0400 relay: Don't log at warn level when we find an address Dirauth code use the warn log severity when calling find_my_address() which made it that every time we would find an address, it would log a warning. These are not needed below info level and thus set them to info level. An IP change is set to notice by default. … [View More]

commit 0767932c890b167088d6697f245cdaad58571c3f Author: Nick Mathewson <nickm(a)torproject.org> Date: Mon Jul 20 11:58:59 2020 -0400 Restore test for bridge presence in networkstatus. Without this check, bridges+hs-v23 seems to be failing. If this works with all our supported versions, I'll figure out what to do with the mentioned issues (chutney#33851 and tor#33852, and also see tor#33407). --- lib/chutney/TorNet.py | 8 ++------ 1 file changed, 2 insertions(… [View More]
