commit f7c97cd40b92084164952dadf3dfeb6164aa6826 Author: Linus Nordberg linus@torproject.org Date: Wed Sep 5 13:35:39 2012 +0200

Remove AuthDirPublishIPv6 and let AuthDirHasIPv6Connectivity fill its function.

See #4771 for rationale.

Note that this patch does not take suggested changes in #4470 into account and keeps treating AuthDirHasIPv6Connectivity as an AUTOBOOL. Thus, bug fixes for that are included here as well.

This is a fix on master, unreleased as of now. --- doc/tor.1.txt | 15 ++++----------- src/or/config.c | 1 - src/or/dirserv.c | 12 +++++------- src/or/or.h | 1 - 4 files changed, 9 insertions(+), 20 deletions(-)
