Subject: refuse to build a circuit before the directory has arrived
X-Git-Tag: tor-0.0.8pre1~84
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=017d7d1fb3f03cc421186c92bfb2e1350b4b7c0b;p=thirdparty%2Ftor.git

refuse to build a circuit before the directory has arrived
this will prevent a few of the 'couldn't decrypt onionskin' errors, maybe
