[Calypso-maint] Bug#865520: calypso: does not listen on IPv6 address

[Roland Hieber]

Package: calypso
Version: 1.4
Severity: normal
Tags: ipv6

Dear Maintainer,

I tried to find an option to let calypso listen on IPv6, but I found none.
I'm starting calypso over a minimal systemd unit file:

	------------- 8< ------------- /etc/systemd/system/calypso.service
	[Unit]
	Description=Calypso Git/CalDAV server
	After=network.target

	[Service]
	ExecStart=/usr/bin/calypso -f -s -k /var/lib/dehydrated/certs/rohieb.name/privkey.pem -c /var/lib/dehydrated/certs/rohieb.name/fullchain.pem -p 5233 -H rohieb.name

	[Install]
	WantedBy=multi-user.target
	------------- >8 -------------

The config is as follows:

	------------- 8< ------------- /root/.config/calypso/config
	[acl]
	type=htpasswd
	encryption=sha1
	filename=/root/.config/calypso/htpasswd
	------------- >8 -------------

However, netstat only shows an IPv4 socket on port 5233:

	# netstat -nlp |grep 5233
	tcp        0      0 37.221.197.195:5233     0.0.0.0:*               LISTEN      30480/python 

It would be great if calypso also worked over IPv6.
