kdepimlibs Epic

Status

Status as at 20 Nov 2013.

• Akonadi supports Qt 5 since release 1.11
• All kdepim has CMake automoc
• Stephen Kelly has been doing clean-up tasks in master (see gitk --author=steveire)
• Stephen Kelly has a frameworks branch on his clone which has deleted KResources and KCal and is making build fixes
• The frameworks branch on kdepimlibs is outdated, but Stephen will merge his branch in due course
• Maintainers are requested to fill in the Code Units grid below

Planning

At the KDE PIM sprint the following plan was discussed on the assumption that no work had been started yet, so it was better to wait until the kdelibs split had been performed:

• Wait for the kdelibs split to be completed and the preview release to be made
• A frameworks branch to be created in kdepimlibs
• All obsolete libraries to be deleted
• Qt5 / KF5 basic porting to be performed mostly by the Frameworks team (old frameworks branch to be reviewed and deleted)
• Once work is started here no more style fixes to be applied to Master
• Code relying on qt3support and deprecated libraries will be removed as part of the porting
• All classes to be reviewed by key maintainers to decide if any should move elsewhere
• Once basic porting is completed then kdepimlibs will be spilt into separate frameworks
• Once split the maintainers of each framework will take over work to make any API and code changes required
• PIM Frameworks will be released as and when they are ready, we do not need to release them all at the same time
• PIM Frameworks will be prioritised depending on usage, i.e. libraries needed by KDE Workspaces and Kolab should be released first
• kdepim-runtime will be split between PIM Framework and kdepim

Since then Stephen Kelly has advised he has already completed significant parts of the port and is recommending the following plan be followed:

• Clean-up in Master branch
  • Port away from obsolete code
  • Includes
  • Q_SLOTS and Q_SIGNALS
  • kde4_add_library -> add_library
• Merge to frameworks
• Delete obsolete code from frameworks branch
• Port to Qt5 / KF5
  • Adapt to upstream api changes, includes, cmake, etc
  • Use kde4support as required
• Remove use of kde4support
• Code rearranging
  • Internal library splits, merges
• Code improvements
  • API changes
  • Refactoring
• Coding Style fix
• Split
• Release

Policies

See the other Frameworks pages for the KDE Frameworks Policies, the kdelibs Split Policies and the Definition of Done .

The kdepimlibs specific policies are:

• Modules that use qt3support are to be removed
• Deprecated API is allowed to be removed
• Source compatibility requirements are relaxed due to fewer clients, but major rewrites are discouraged. Instead port the old library and create a separate new library (e.g. KHolidays and QHolidays).
• Most libraries will aim for Tier 2, but some may be able to target Tier 1.
• The initial KF5 port may rely on kde4support to enable the port to be performed by non-experts, but no Framework released may rely on kde4support so the maintainer must remove all usage. In particular all KDateTime, KTimeZone and KLocale usage must be removed and the Qt replacements throughly tested for regressions and behaviour changes.

Priorities

The following libraries are known to be used outside of KDE PIM and so may be a higher priority in porting.

For Plasma support the decision has been made to deprecate the use of DataEngines and use QML includes instead.

Priority items:

• Akonadi
• KABC
• KCalCore
• KMime
• KHolidays
• QGpgme
• KXMLRPCClient
• + other Kolab libs

kde-workspace

Usage:

• kde-workspace/libs/plasmaclock/
  • KHolidays (for selection widget, could be moved elsewhere?)
  • CalendarEngine
• kde-workspace/plasma/generic/dataengines/akonadi/
  • Akonadi
  • KMime
  • KABC
  • Microblog
  • KPimUtils (linked but not included?)
  • AkonadiEngine not used anywhere
• kde-workspace/plasma/generic/dataengines/calendar/
  • Akonadi
  • KCalCore
  • KCalUtils
  • KHolidays
  • CalendarEngine only used in kde-workspace/libs/plasmaclock/
• kde-workspace/plasma/generic/dataengines/rss/
  • Syndication

Note: It is recommended that the Akonadi DataEngine be reworked/renamed as EMailEngine, ToDoEngine, etc, as this is client developer facing API and so the implementation name should be abstracted/hidden from them, i.e. as is done with the CalendarEngine.

kde-runtime

Usage:

• kde-runtime/drkonqi/
  • KXMLRPCClient
• kde-runtime/kwalletd
  • QGpgme

kdeplasma-addons

Usages:

• kdeplasma-addons/libs/lancelot-datamodel
  • Akonadi - for email support
• kdeplasma-addons/runners/contacts
  • Akonadi
  • KABC
• kdeplasma-addons/runners/events
  • Akonadi
  • KCalCore
• kdeplasma-addons/applets/news/
  • RssEngine
• kdeplasma-addons/applets/rssnow/
  • RssEngine

Runners could be converted to either use KPeople, or to use the QML includes? Or the DataEngines?

Kolab

WIP. Basically most of the lower-level libraries and all of kdelibs!

• KIMAP
• KABC
• KCalCore
• KMime

Code Units

The following is a high-level list of the different Code Units in kdepimlibs and kdepim-runtime. A Unit may be a library or other software artefact that is to be considered as a stand-alone unit of code.

Initial listing of top-level directories and the README and MAINTAINERS files. If subdirectories need breaking out separately then please add to list.

Note that the status listed in this table is solely whether the information required has been completed, not that theport has been completed.
