Development Team/Collaboration Refactoring

From Sugar Labs
Jump to: navigation, search

Introduction

During the 0.90 release cycle, Collabora is sponsoring the refactoring of the presence and collaboration framework in Sugar with the following objectives:

  • reduce the dependency on deprecated or soon to be deprecated parts of the Telepathy spec,
  • improve interoperability with other messaging systems,
  • make it easier to implement further collaboration features, often developed for other systems.

The strategy that will be followed can be summarized as turning Sugar into a normal Telepathy client.

Instead of implementing these changes inside Sugar's Presence Service, we are going to remove this layer because of the unneeded complexity that it brings and because several of the services it provides are either obsoleted or replaced by new components in the Telepathy framework. See Development Team/Presence Service Removal for details.

Tasks for 0.90

Reimplement presence in the Shell

Work ongoing in http://git.sugarlabs.org/projects/sugar/repos/nops based on Development Team/Presence Service Removal. This is the base for all the rest of improvements to the collaboration infrastructure.

Status: feature complete, polishing and stabilization ongoing

Dispatch new channels

  • Implement an approver and display the invitation in the UI
  • Make sure other telepathy clients don't interfere even if installed

Status: feature complete, polishing and stabilization ongoing

Reimplement sugar.presence without the PS

Instead of having the logic split between sugar.presence and the PS, implement what is needed inside sugar.presence using the D-Bus API.

Status: feature complete, polishing and stabilization ongoing

Implement compatibility PS based on sugar.presence

For activities that still depend on the PS D-Bus API.

Status: in progress

Tasks for future releases

Implement a non-Sugar-specific interface for announcing activity

An important part of the Sugar experience is that users can choose to do any of their work either alone or together with other people, so the UI displays on-going activities, allows joining existing activities, sharing a local activity, inviting other people to an on-going activity, etc.

There's interest in systems other than Sugar that also use Telepathy to gain similar capabilities, so we are going to work in defining better the intended user experience and designing a Telepathy interface for this.

Account configuration in the control panel

Sending and accepting subscription requests

Adding an arbitrary contact to our contact list

Avatars support

Merge Salut and Gabble contacts in the UI (?)

Make activities activatable dbus services

So they can be activated in other desktops.
