That's right. I don't think that it is possible to change the Curl_ipv6works() implementation that it will work the same way with zero delays for ALL possible kernels/network configurations. And it is not possible to change all kernels where some curl application may run to make Curl_ipv6works() return false with 0ms delay when there are some issues with IPv6 on kernel levels.
What I cannot understand is how you can implement a working callback for this purpose, called when the connection is to setup, but you cannot set an easy option, done just before the connection is about to get setup.
Why would one work and not the other? -- / daniel.haxx.se | Commercial curl support up to 24x7 is available! | Private help, bug fixes, support, ports, new features | https://curl.se/support.html -- Unsubscribe: https://lists.haxx.se/listinfo/curl-library Etiquette: https://curl.se/mail/etiquette.html
