Calendar Support #469

Open kamarya opened 2 years ago

kamarya commented 2 years ago

Use case

Calendar support for WebDAV, CalDAV and CardDAV.

What problem you are trying to solve?

A monolithic integration of calendar service and mail. The calendar then uses the same credentials of the mail users.

How your solution would work in general?

Use go-webdev package to provide calendar service: https://github.com/emersion/go-webdav

A new thread serves the calendar along with mail service on other threads. Sharing the same credentials and facilitating the usage of both services is the key.

will be cool, @foxcpp do you know how this can be integrated with maddy?

foxcpp commented 2 years ago

go-webdav needs a lot of work before it can be used as a production-ready CalDAV/CardDAV implementation.

And we probably need a generic HTTP endpoint implementation in maddy first (some discussion in #374). After all that, integration should be as simple as providing an appropriate FS interface implementation built around existing maddy abstractions.

We can start with HTTP reverse-proxy that would run in front of a proper WebDAV implementation and use maddy's authentication modules.

vtolstov commented 2 years ago

we can start with non prod ready and mark it experimental like some modules in linux kernel,

Sounds like a good candidate for a scope creep. Wouldn't it make sense to use more mature Baikal/EteSync?

kamarya commented 2 years ago

@savchenko what about having two separate source of credentials ? Maddy is not (yet) targeting more complex authentication methods like LDAP. So to have a seamless calendar support, it should be part of Maddy. Nowadays calendar is part of the email services.

foxcpp commented 2 years ago

@kamarya FWIW, maddy has LDAP auth support ( using credentials binding)

kamarya commented 2 years ago

Even with LDAP support I do not think integrating calendar into maddy is a "scope creep". The reason I use maddy is the fact that it packs up several services into one. It is simple to setup and maintain (so far) and calendar is a so necessary element alongside an email service.

technodrome commented 2 years ago

Mail server should be just that - a mail server. Mail has nothing to do with a calendar. While I understand the desire to have a convenient combo, this really is a great candidate for a scope creep.

There's radicale, etesync or https://github.com/emersion/go-webdav - and even they themselves don't even offer any kind of well-rounded documentation to use their package yet (judging by this).

Complicating dev's life with adding something that bloats the business case while not even IMAP storage is marked as production-read would probably not be the wisest choice out there.
