* fix(netxlite): make default resolver converge faster Closes https://github.com/ooni/probe/issues/1726 * Update internal/netxlite/resolver.go * fix(ndt7): adapt tests after previous change Because now we're running the DNS resolution inside a goroutine with a child context, the returned error string is different. The previous error said we canceled the whole dialing operation, while now we see directly that the context was canceled.
