@@ -6,6 +6,26 @@ Changelog +Daniel Stenberg (2 Nov 2008) +- Daniel Johnson reported and fixed: + + When c-ares isn't enabled, libcurl by default calls getaddrinfo with family + set to PF_UNSPEC which causes getaddrinfo to return all available addresses, + both IPv4 and IPv6. Libcurl then tries each one until it can connect. If the + net connection doesn't support IPv6, libcurl can still fall back to IPv4. + + However, since c-ares doesn't support PF_UNSPEC, when it's used it defaults + to using family=PF_INET6 and therefore only returns IPv6 addresses when AAAA + records are available, even if IPv4 addresses are also available. The effect + is that since my ISP doesn't do IPv6, libcurl can't connect at all to a site + that has AAAA records. It will work if I explicitly use CURL_IPRESOLVE_V4 or + --ipv4 with the curl tool. I discovered this when curl would fail to connect + to seemingly random sites. It turns out they weren't random, they were sites + with AAAA records. + + So now libcurl defaults to PF_INET... until c-ares has been tought to offer + both. + Daniel Fandrich (29 Oct 2008) - Fixed a bug that caused a few bytes of garbage to be sent after a curl_easy_pause() during a chunky upload.
