From ca416a78e3570a62bf471abde8432208a660f8c5 Mon Sep 17 00:00:00 2001 From: Roger Dingledine Date: Thu, 5 Jun 2008 10:57:09 +0000 Subject: [PATCH] When we switched to using v3 directories, we threw away the part of the "do we have enough directory info?" calculation that checked how many relays we believed to still be running based on our own experience. So if we went offline, we never gave up trying to make new circuits; worse, when we came back online we didn't recognize that we should give all the relays another chance. Bugfix on 0.2.0.9-alpha; fixes bugs 648 and 675. svn:r14970 --- ChangeLog | 9 +++++++++ src/or/routerlist.c | 21 +++++++++++++-------- 2 files changed, 22 insertions(+), 8 deletions(-) diff --git a/ChangeLog b/ChangeLog index 738c0306b6..9015c68658 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,4 +1,13 @@ Changes in version 0.2.1.1-alpha - 2008-??-?? + o Major bugfixes: + - When we switched to using v3 directories, we threw away the part of + the "do we have enough directory info?" calculation that checked + how many relays we believed to still be running based on our own + experience.
