commit fcac4b4467427e8f6ad948e8c8e6f34a0131e716 Author: Roger Dingledine arma@torproject.org Date: Tue Aug 5 16:54:46 2014 -0400
Build circuits more readily when DisableNetwork goes to 0
When Tor starts with DisabledNetwork set, it would correctly conclude that it shouldn't try making circuits, but it would mistakenly cache this conclusion and continue believing it even when DisableNetwork is set to 0. Fixes the bug introduced by the fix for bug 11200; bugfix on 0.2.5.4-alpha. --- changes/bug11200-caching | 7 +++++++ src/or/nodelist.c | 21 ++++++++++++--------- 2 files changed, 19 insertions(+), 9 deletions(-)
