IPv6 cluster

[j3k0]

I cannot setup a IPv6 cluster, because the _cluster_setup action add_node doesn't accept IPv6.

curl -H 'Content-type: application/json' "admin:password@host1.vlan0:5984/_cluster_setup" -d '{"action": "add_node", "host":"host2.vlan0", "port": 5984, "username": "admin", "password":"password"}' | jq
{
  "error": "invalid_ejson",
  "reason": "{conn_failed,{error,nxdomain}}",
  "ref": 878456848
}

• host1.vlan0 resolves (AAAA) to an address similar to abcd:1234:abcd:1234:abcd:123:abcd:1
• host2.vlan0 resolves (AAAA) to an address similar to abcd:1234:abcd:1234:abcd:123:abcd:2

When trying to set the "host" to the IPv6 address, I get:

{
  "error": "invalid_ejson",
  "reason": "{url_parsing_failed,{error,invalid_uri}}",
  "ref": 878456848
}

I also try to include the IPv6 between [ ] (thinking maybe couchdb tries to setup a URL like http://{ host }:{ port }) ... but it fails with the same error as if I used an hostname (error, nxdomain). (I wonder if there's a regex figuring out if the thing is an IP that only matches IPv4?)

Note: another hiccup was that apache.jfrog.io does not resolve in IPv6 (solved by downloading and copying the deb file manually... meh). But that's a different issue.

Tried the same yesterday and got "invalid URL" it's a pity 🥺

Can you append the section of your log where the error occurs?

The latter might be related to #5223, it looks like there's some URL string manipulation bugs.
