NOT an issue of whether apr's IPv6-enabled.
It is either an APR issue, or a packaging issue. APR's apr_sockaddr_info_get function, which Subversion uses to resolve a hostname, does not have a flag to enable or disable IPv6 DNS lookups. All your list above proves is that your APR does not support DNS lookups to IPv6 name servers. I don't know whether this is a general limitation of APR, or whether your particular version of APR is too old, or compiled in a way that those lookups are disabled. In any case, I suggest you take that question to the APR developers; it's d...@apr.apache.org. But please be prepared to give a bit more information about your environment, starting with your OS version and APR version. -- Brane -- Branko Čibej | Director of Subversion WANdisco // Non-Stop Data e. br...@wandisco.com
