Subject: Fix async callbacks in unit tests now that ResolverContext is no longer an optional
X-Git-Tag: dnsdist-1.9.0~16^2~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c5e868605f6fa4f87836252982bcf82acf1fed91;p=thirdparty%2Fpdns.git

Fix async callbacks in unit tests now that ResolverContext is no longer an optional

Note that C++ does not really care, as the implicit conversion rules cover
this already.
