Event attendance should be backed by DAV

[chibenwa]

Why

Do like blue bar in OpenPaaS INBOX.

Exact synch between calendar and TMail.

• I should see my attendance status
• Updates should work for all invitations, not just OpenPaaS ones.

No longer rely on HTML parsing...

Summary

• Tmail backend should advertize a DAV URL using https://github.com/linagora/tmail-backend/issues/588 here https://dav.linagora.com
• Tmail backend should advertize an OpenPaaS backend URL using https://github.com/linagora/tmail-backend/issues/588 here https://openpaas.linagora.com
• TMail frontend given an EML will query the DAV URL in order to retrieve attendance status and update it if necessary

Request breakdown

Same creds than Tmail shall be used with the DAV server.

@chibenwa : so we should be able to advertize multiple DAV urls with discovery endpoint correct? Separated let's say by commas? Or was it a copy/paste mistake, cause I don't see the point... one should be enough as it is the same dav system in the end.

Like:

davApiUrls=https://dav.linagora.com,https://openpaas.linagora.com

Or just:

davApiUrl=https://dav.linagora.com

After confirmation I will create the task on the backend backlog :)

[chibenwa]

No, it is a mistake on my side.

We shall advertize link to OpenPaaS backend AND the DAV URL...

[Arsnael]

FYI: https://github.com/linagora/tmail-backend/issues/887

[dab246]

@hoangdat Do we have a design that has it yet?

[chibenwa]

Closed in favor of https://github.com/linagora/tmail-flutter/issues/2425 . No DAV invovled.

The design would be the same as today with OpenPaaS invites OpenPaaS.

We just need to add a Reply sentconfirmation message.
