[tor/master] Don't build descriptors if ORPort auto is set and we have no OR listener
by nickm＠torproject.org 30 May '11

commit 95ac3ea5946f723ddab474fe229a872669aee47f Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue May 17 21:42:35 2011 -0400 Don't build descriptors if ORPort auto is set and we have no OR listener This situation can happen easily if you set 'ORPort auto' and 'AccountingMax'. Doing so means that when you have no ORPort, you won't be able to set an ORPort in a descriptor, so instead you would just generate lots of invalid descriptors, freaking out all the time. Possible fix for 3216; fix on 0.2.2.26-beta. --- changes/bug3216 | 4 ++++ src/or/router.c | 4 ++++ 2 files changed, 8 insertions(+), 0 deletions(-) diff --git a/changes/bug3216 b/changes/bug3216 new file mode 100644 index 0000000..599b5e1 --- /dev/null +++ b/changes/bug3216 @@ -0,0 +1,4 @@ + o Major bugfixes: + - Don't try to build descriptors if "ORPort auto" is set and we + don't know our actual ORPort yet.

[tor/master] Don't try to build descriptors when router_get_advertised_or_port()==0

commit 0e1fad648d22923d7455b94734df36585b8f624f Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue May 24 11:55:08 2011 -0400 Don't try to build descriptors when router_get_advertised_or_port()==0 The previous attempt was incomplete: it told us not to publish a descriptor, but didn't stop us from generating one.
