[reSIProcate] Followup on c-ares support

[Dario Bozzali]

Hi,
I don't know if this is the right thread to post this mail.
Anyway in my opinion during c-ares integration in Resiprocate, it has been introduced a very little mistake in a log in AresDns.cxx
In particular in AresDns::internalInit() method in SVN head was inserted the following code:
           WarningLog (<< "Ignoring non-IPv4 additional name server "
#if defined(USE_ARES)
                       "(not yet supported with c-ares)"
#elif defined(USE_CARES)
                       "(IPv6 support was not enabled)"
#endif
                       );

If I'm not wrong the two logs must be switched:
           WarningLog (<< "Ignoring non-IPv4 additional name server "
#if defined(USE_ARES)
                       "(IPv6 support was not enabled)"
#elif defined(USE_CARES)
                       "(not yet supported with c-ares)"
#endif
                       );

Sorry if this was not the right thread.

Best regards,
Dario.

I don't have the actual benchmarks at hand, but Byron and I discussed first-cut performance results. Doing some very DNS-heavy processing (i.e., each request was associated with a different DNS record, so no caching was possible), I think he said that we were able to push almost twice as many SIP transactions through repro with c-ares than with the built-in ares.

Normal disclaimers apply (we may have overlooked something, YMMV, etc).
