Kontact Inventory

We need to go through the current codebase, assess what features are available, how the implementation looks and where it is, and to what extent the code is reusable. This will help us in figuring out the useful feature set, and will allow us to reuse the lessons learned that are embedded in the codebase.

This inventory is currently hosted in an ikiwiki (ikiwiki.info) git repository(kde:scratch/aseigo/KontactCodebaseInventory.git)

Target platforms

The codebase is supposed to be portable across a range of platforms. Initially we'll work on a reasonably recent linux distribution though.

The aimed for minimum bar is:

Linux:

  • Fedora 22
  • Ubuntu 12.04
  • Centos/RHEL 7

Windows:

  • 7sp1

OS X:

  • ?

Android:

  • 5.0

Dependencies

Since the codebase needs to be portable across various platforms old and new, dependencies should be managed that they are as little and as low as possible. While we don't want to reinvent the wheel constantly or work with ancient technology, each additional dependency or dependency bump needs to be justified and we need to evaluate wether that results in a problem with any of the target platforms. This evaluation of course includes transitive dependencies.

Currently available dependencies:

  • GCC 4.6.3 / MSVC 2013
  • Qt 5.2
  • kf5-kpackage ** Used as installation format for all qml parts. Intended to serve as abstraction layer to allow replacing certain modules on differnet platforms/formfactors.
  • kf5-kcodecs ** dependency of kmime, email address handling (KEmailAddress)
  • kf5-kmime ** Parsing and assembling of mails
  • libcurl 7.20 ** mailtransport
  • libkleo ** crypto-stack, currently only gpg
  • libotp ** parsing and html rendering of emails

Codebase

Requirements

  • Each module has at least rudimentary tests that can then be extended
    • Tests need to be deterministic, no random timeouts to check if something already happened, only QTRY_VERIFY and alike is allowed.
  • Clear layering. No depending on Sink from everywhere.
  • Each module comes with a clear set of justified dependencies.
  • Commented code is only allowed in conjunction with a task in phabricator. No dead/commented code.
  • Each module requires a clear interface that allows the module internals to be replaced eventually.
  • UI modules need to be separated from non-UI parts. All UI parts need to be eventually replacable by QML equivalents.
  • No dialogs in non-UI parts.
  • New features are only added after having been selected from the roadmap for a future release
  • An accounts based configuration for everything
  • No non-persistant data in config files (collection ids...)

  • No KParts

  • No KXMLGui

Guidelines

  • Singletons that hold a modifyable state should be avoided.
  • Where standards are available we strive to follow those, and deviations from the standard are avoided as much as possible. Repurposing of standard elements should be avoided altogether.
  • Fallbacks (i.e. for configs ), should be applied in a single place only, and should be avoided wherever possible.
  • Libraries need to be purpose built and with clear responsibilities. No artificial boundaries that don't help something.
  • Modal dialogs should be avoided.

Coding Guidelines

  • Run the tests before you push

    • Automation (Wallace)
    • Extensible / Theming
    • Multiple open instances

Features

A list of features that has to be refined and put on the roadmap on phabricator. This is very much WIP and the features listed here are largely coming from what is existing in Kontact and the Kolab Groupware Server.

General

  • autoconfiguration/automatic setup/preconfiguration: The complete setup process should require a minimum of configuration and should be fully scriptable.

Mail

  • folderlist (with search)
  • smart folders
  • multi account & identity
  • threading/conversation view
  • actions
    • flags: read/unread/important
    • delete/move/copy
    • reply to/reply to all/forward
    • bulk operations on selected/thread
    • move to special folder
      • archive
      • move to trash
  • attachments
  • crypto
  • search
  • tags
  • create event/todo from mail
  • snippets
  • mail composer
  • shared folders / acls
  • undo

Calendar

  • calendarlist (with search)
  • smart calendars
  • multi account & identity
  • create/edit/modify event/todo (journal?)
  • week/month view
  • ical import/export
  • delegation of events/todos
  • iTip handling
  • freebusy for scheduling
  • tags

Notes

  • notebooks
  • create/edit/modify note
  • tags
  • note editor
    • title/content

Todos

  • todolists
  • create/edit/modify todo
  • tags
  • todo editor
    • summary/content/start date/due date
  • delegation of todos

Feature Brainstorming

  • Why is it the sender of a message that dictates how/where I receive/read the message?
  • VOIP system knows when you're away, allows to forward the call to your mobile

Desktop

  • Autocomplete conversations from sent folder: Automatically merge sent messages that belong to a conversation/thread from the sent folder (making it unnecessary to send a copy to yourself or alike)
  • Inbox for everything: upcoming events, uncategorized todos, open invitations, email, delegated todos. This could either be a mixed inbox for everything (as in what you have to go through), or an overview page with multiple inboxes.
  • No invitation in mail inbox: Mail is a transport mechanism and there is little reason to clutter your mail inbox with invitations. So move invitations to a separate queue.
  • Fuzzy match on folder search: It should be as easy and fast as command-t for vim (meaning as fast as you type)

Mobile

  • Swipe left right through email inbox (tinder for kolab aka "kinder")
    • Same works for invitations (accept/decline)
    • Same for todos, done/do later (if not touched keep for today)
  • Quick inline reply in mails (what's app style)
  • Note taking/todo management on the run, with categorization workflow on the desktop (or also on mobile)

Platforms

Desktop linux is the primary platform that we'll pursue first, because it's the easist target. As soon as we have a viable proof of concept and the architecture is set, Windows and OS X will follow, so we ensure early on that the project works on all platforms.

Android will be tried in the form of a research project, and depending on the difficulties we face the situation will be reevaluated.

Deliverables

These are the high-level aims that we have to work towards. This list is not a final list of deliverables, but should convey the areas we need to work on. More detailed information should eventually be available on phabricator.

  • Project Vision

    • Target Users & Usecases
      • Personas
      • Scenarios
      • Description of environment
    • UI Mockups for envisioned clients
    • The target feature-set
  • Milestones

    • First working product: A simple email application for the linux desktop
      • read-only first
      • read-write second
    • Some intermediate releases: Largely depends on what deliverables we want, and wether we can use releases that only contain a subset of the groupware types.
      • Application by application (calendar, email, ...)
      • First release on other platforms (e.g. android)
    • Production ready (1.0): Includes calendar, email, addressbook, notes, tasks with basic functionality (which we need to define)
    • From here on we implement feature by feature from the roadmap
  • Implementation

    • Inventory of exiting kdepim: This will help to fill the functional blocks, and help in carving out the require featureset.
    • Functional blocks: We need to identify the function blocks that we require, see to what extent they are already existing and how we can reuse what's there already. The functinal blocks should largely follow from the identified requirements.
    • Prototype the domain logic: We need to prototype the domain logic as envisioned to see wether that works out. This will be an ongoing process especially while working towards the first milestone.
    • Prototype with domain logic + Sink + trivial UI. Show that this can work in it's basics.
