From 3c504e3fbf06e042e9799f0947109e6f45db6cdb Mon Sep 17 00:00:00 2001 From: Nick Mathewson Date: Thu, 29 May 2008 00:45:07 +0000 Subject: [PATCH] Backport fix for bug noted by roger: rebuild extrainfo store from time to time, even if we have never actually downloaded an extrainfo. Bridge authorities need this, or they never clean the extrainfo store. svn:r14793 --- ChangeLog | 4 ++++ src/or/routerlist.c | 19 +++++++++++++------ 2 files changed, 17 insertions(+), 6 deletions(-) diff --git a/ChangeLog b/ChangeLog index 9e1303809..9e3668b5e 100644 --- a/ChangeLog +++ b/ChangeLog @@ -17,6 +17,10 @@ Changes in version 0.2.0.27-rc - 2008-05-?? - Allow comments in geoip file. - Make bridge authorities never serve extrainfo docs. + o Minor bugfixes: + - Make bridge authorities correctly clean extrainfo store from time to + time. + o New files: - A new contrib/tor-exit-notice.html file that exit relay operators can put on their website to help reduce abuse queries. diff --git a/src/or/routerlist.c b/src/or/routerlist.c index aaadaf167..538d8e942 100644 --- a/src/or/routerlist.c +++ b/src/or/routerlist.c @@ -559,15 +559,18 @@ _compare_signed_descriptors_by_age(const void **_a, const void **_b) return (int)(r1->published_on - r2->published_on); } -/** If the journal is too long, or if force is true, then atomically - * replace the router store with the routers currently in our routerlist, and - * clear the journal.
