Sync with Cozycloud

[AutoImport-frankrousseau]

Hello there,

Thank you for DAVDroid that is probably a great software. I’m trying to sync my Cozy with a new phone based on Android 4.4.

The DAVDroid installation worked fine but when I try to configure a new account, It keeps on telling that the host is wrong. It can’t find mycozy.cozycloud.cchttps. It looks like the host string is wrongly built.

Did I miss something or is that a bug?

[rfc2822]

1. Redirections MUST always contain absolute URLs. However, cozycloud does not, so DAVdroid tried to build one, which failed. I have fixed the DAVdroid mistake and we should notify Cozy about their mistake (using relative redirection URLs).
2. Even after fixing this, it doesn’t work because cozycloud returns /public/sync as the CalDAV/CardDAV service path, although this is apparently wrong:

$ curl -vX PROPFIND --data @cup.xml -u xxx:xxx https://xxx.cozycloud.cc/.well-known/caldav
> PROPFIND /.well-known/caldav HTTP/1.1
> Authorization: Basic xxxxxxxxxxxxx
> User-Agent: curl/7.32.0
> Host: xxx.cozycloud.cc
> Content-Length: 73
> Content-Type: application/x-www-form-urlencoded
> Accept: */*
> 
< HTTP/1.1 302 Moved Temporarily

< Content-Type: text/plain; charset=UTF-8
< Content-Length: 47
< Connection: keep-alive
< Location: /public/sync/

(Note the incorrect relative Location URL.)

The contents of cup.xml are:

<propfind xmlns="DAV:">
	<prop>
		<current-user-principal />
	</prop>
</propfind>

When trying /public/sync:

$ curl -vX PROPFIND -u xxx:xxx --data @cup.xml https://xxx.cozycloud.cc/public/sync/
> PROPFIND /public/sync/ HTTP/1.1
> Authorization: Basic xxxxxxxxxxxxxx
> User-Agent: curl/7.32.0
> Host: xxx.cozycloud.cc
> Accept: */*
> Content-Length: 73

So this is a CozyCloud error. Would you mind reporting the problem to CozyCloud, referencing this issue for technical details?

Ok I work at Cozy Cloud, I’m not the guy responsible for the Sync module. So, I will pass the information. Thank you.

There is already an issue open mentioning problems syncing DAV. https://github.com/cozy/cozy-sync/issues/24 . We’ll work on it and then come back to you soon after.

Hi @rfc2822, I am the cozy developper responsible for the Sync module.
Ok for your first point, we will change the 302 to an absolute path.

However, for your second, I couldn’t reproduce on frank’s instance. (cf curl stack below). On what cozy instance did you test ? The demo or do you have your own ? If so, have you installed the cozy-sync module ? We recently updated it to rename it from cozy-webdav to cozy-sync, so if you installed it more than a month ago, you might have to uninstall-reinstall it.

Thanks for helping us with cozy’s compatibility.

[rfc2822]

On what cozy instance did you test ?

“dkm.cozycloud.cc”, provided by a user.

[rfc2822]

@aenario, where you able to reproduce the problem with the dkm instance?

Or can you maybe provide a test account for us so that we can test DAVdroid against Cozycloud?

[AutoImport-frankrousseau]

Could you provide us with an email? So we could create an instance for you.

[rfc2822]

Of course, please send the details to play@bitfire.at

[rfc2822]

@frankrousseau @aenario Thanks! But I got the 404 error on PROPFIND /public/sync for our instance, too. (At the moment, I get Bad Gateway, but I guess that will be temporary.)

[rfc2822]

Any news on this?

[AutoImport-frankrousseau]

We didn’t find time to investigate it. We’ll work on it next week. Sorry for the delay.

Hi rfc2822, it appears you havent installed the webdav module in your cozy instance.
You need to go to https://play.cozycloud.cc/#applications and choose the “sync” module from the list.

Thanks, I was now able to get it working by installing the Sync module. I’ll add instructions to http://davdroid.bitfire.at/configuration
