[or-cvs] [tor/master] Update Tor to use Libevent 2.0 APIs when available.
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date: Thu, 4 Jun 2009 01:05:23 -0400
Subject: Update Tor to use Libevent 2.0 APIs when available.
Commit: e5b88dc83fb44622f2b0f9c0c242907d1c02311f
This patch adds a new compat_libevent.[ch] set of files, and moves our
Libevent compatibility and utilitity functions there. We build them
into a separate .a so that nothing else in src/commmon depends on
Libevent (partially fixing bug 507).
Also, do not use our own built-in evdns copy when we have Libevent
2.0, whose evdns is finally good enough (thus fixing Bug 920).
