Topics

Please add topics you would like to cover here:

  • KDE PIM 4.6 release
  • Kontact touch, demo on several devices if people are interested (N900, HTC Touch Pro2, Ideapad, Aava Mobile Smartphone, Wepad). Experiences, especially size.
  • KDEPIM and professional development, credits discussion
  • Kontact from KDE 3 under KDE Platform 4, config file clashes?
  • Outlook invitation compatibility and "enterprise" setting in general. Ideally, we would like to reduce each point
  • sqlite vs mysql and the indixes, measuring and example data
  • Webpresence of Kontact and KDE PIM is lacking a lot
  • Kontact (Desktop and Touch) on windows
  • experiences with setting up the continuous build systems for Kontact Touch on Maemo and CE: problem of full builds -> saegerwerk. Problem of included files and dependencies.
  • is a better maintainer for ktimetracker available (question from tstaerk)?
  • Git workflow ( fwd port with git-merge or git-cherry-pick? )
  • N900 performance problems. Still spurious appointment conflicts when syncing.
  • Summer of Code ideas brainstorming
    • Merged contact view in KAddressbook
    • Social networking resources (Studivz, LinkedIn etc)
    • ...
  • Trash handling in Akonadi
  • Import/Export in Akonadi
  • Exchange support status?
  • Nepomuk integration for Calendar Incidences and Notes?
  • Demo of my hackweek project (Cornelius)

4.6 Release and Migration

Migration

Last remaining blocker: Mail migration.

  • Fails in error cases (no wallet, no network)

Solution:

  • Make migration is optional
  • Fix migrator error scenarios
  • Fix no wallet scenario

PR

New features:

  • IMAP IDLE
  • Per-folder cache policies
  • New touch front-ends
  • New calendar/contact backends (Google, Facebook, DAV, etc)
  • Plasma access to the calendar, Plasma mail front-end
  • TODO

Messageing

  • Ready to use, but very distruptive technology change.
  • Highlight application changes, not backend changes.
  • TODO

Plan

  • Fix migrator (ideally this weekend)
  • RC release ASAP (ca. March 2nd with 4.6.1)
  • Final release in about a month (4.6.2, April 5th)

Trash Handling

TrashJob

  • Delete Item if already marked as deleted
  • Move to trash collection if available
  • Flag item with MarkAsDeleted attribute

MarkAsDeleted attribute:

  • collection to restore Item

(can be translated by the resource, i.e. to the imap mark as deleted flag)

TrashSetting

Per Resource Setting:

  • TrashCollection: For remote resources the applicaton could still setup a separate resource with a local storage format which is used as trash.
  • Time before MarkAsDeleted items are deleted by the janitor agent(based on modificationTime of item)

TrashFilterProxy

Hide MarkAsDeleted items, except if parent collection is a trash collection

StandartAction

  • DeleteAction -> DeleteJob
  • TrashAction -> TrashJob

Janitor Process

Process to delete items based on MarkAsDeleted attribute and the configuration how long items should be kept

Database

  • Search for git log about reason for sql indices (hours)
  • Bulk import API (hours)
  • Email Dataset Korpus (Enron-Template) (hours-days)
  • Low Level DB Introspection API (days)
  • Transaction Scheduling (R/W Queue) (weeks)
  • Nested Sets (weeks)
  • Reuse of Prepared Statements
  • Correctness of SQLite (constraints)
  • (updateable) Views
  • improved Object Relation Mapper

Git Workflow

  • Enterprise branches: clone or branch? -> branch
  • Central model, like with SVN
  • Follow general KDE rules, discuss in general KDE context

Enterprise Build Options

  • Compliant with RFC/standards/specifications or compatibility with other solutions (eg. Outlook/GMail)
  • Thomas will compile a list of existing differences depending on KDEPIM_ENTERPRISE_BUILD, individual options will be discussed on the on the mailing-list
