Cleaning up kdelibs

Next to the other efforts for kdelibs modularization, there's also some cleanup tasks which needs to be done accross the whole kdelibs codebase. Tasks in here are probably more suitable for short term, bite sized involvement.

Note: For most of those tasks we try to put an estimation of the difficulty can be: easy, normal, hard (somewhat like in video games). ;-)

Status Description Contact
DONE remove kglobal.h include from staging/kwidgets/src/icons/kiconloader.h, fix compilation by adding the header where necessary (easy) Christoph Cullmann
DONE move ktypelist.h from kdecore/util to kde4support (easy) Christoph Cullmann
DONE move kentrymaptest from kdecore/tests to kconfig/autotests (easy) Christoph Cullmann
DONE move kascii and kasciitest to kde4support (easy) Christoph Cullmann
DONE Port away from KGlobalSettings::singleClick() (easy) Dominik Haumann
DONE #cmakedefine -> #cmakedefine01, #ifdef -> #if, in order to catch missing includes (easy) Nicolas Lécureuil
DONE Port from KCmdLineArgs+KApp to QApp+setApplicationName in all unittests that don't use args (easy) Jeremy Whiting
DONE kio/netaccess.h: there are some "TODOs" about deprecating most methods in favour of job+exec (TODO: compare with synchronousRun) (normal) Àlex Fiestas
DONE Port all of kdelibs from NetAccess::synchronousRun to job->exec, including unittests. This will make it possible to move kio/tests/jobtest.cpp and jobremotetest to staging/kio (and only link them to kiocore). There's a left use in accessmanager.cpp Aleix Pol


DONE Fix kfileplacesmodeltest (normal) Benjamin Port


DONE Move to kcoreaddons the tests in kdecore/tests that are actually tests for classes in kcoreaddons, except kurltest (easy) Anne-Marie Mahfouf


DONE "cp kurlmimetest.cpp kurlmimedatatest.cpp" and port the second one to KUrlMimeData (in order to test both the deprecated API and the new API). After that, move the old one (kurlmimetest) to kde4support. (normal) Lambert Clara


DONE Port kcmdlineargs from KUrl to QUrl, then move KUrl out of kcoreaddons, and into kdecore for now, final destination will be kde4support. (easy) Matt Williams


DONE Port kdelibs from KProcess to QProcess (except kpty and KRun) (easy). Warning: Need to port some functionnality to Qt 5 Martin Sandsmark


DONE Update qmimetype in kdelibs from the one soon merged to Qt5, port all of kdelibs to the API changes. (normal) David Faure


DONE Create a staging/kconfig framework out of kdecore/config + kdecore/kernel/kauthorized*. Code should be ready (no more dependencies on the rest of kdecore). (normal) David


DONE Port all of kdelibs from KGlobal::config() to KSharedConfig::openConfig(), adjust includes (easy) Claus Christensen


DONE Port all of kdelibs from KMimeType to QMimeType, see KDE5PORTING.html for details (easy) David Faure


DONE deprecate KLineEdit::clickMessage, by applying https://git.reviewboard.kde.org/r/101360/diff/#index_header and porting kdelibs (easy and quick) Benjamin Port


DONE Move KDialog saveDialogSize+restoreDialogSize to static methods taking a QDialog. Benjamin Port


DONE Go through all users of KEMailSettings (e.g. in lxr.kde.org) to find which methods are actually used, deprecate the others Martin Klapetek


DONE Replace usage of KSocketFactory by the implementation of the method (it's very short). Kevin Ottens


DONE Move KFileMetaInfoItem and PredicateProperties from kio, as well as kfile/kfilemetadatareader* to kde4support

https://git.reviewboard.kde.org/r/111897/

[email protected]


DONE Finish deprecating methods marked as @deprecated (add macro+ifdef, ensure kdelibs doesn't use). Benjamin Port and Kevin Ottens


DONE Move kio/kfile/kdiskfreespace.cpp to kde4support https://git.reviewboard.kde.org/r/111605/ [email protected]


DONE Move K4AboutData and KComponentData to kde4support (not used anymore, apparently) [email protected]


DONE Replace signals: with Q_SIGNALS: and slots with Q_SLOTS: everywhere in kdelibs (to make moving less work) https://git.reviewboard.kde.org/r/111609 [email protected]


DONE Move tests that didn't follow their classes. E.g. kcompositejobtest from kdecore/tests to kcoreaddons/autotests. Kevin Ottens


DONE Move KDialogQueue into separate files. Benjamin Port


DONE Port all of kdelibs (except kde*support and classes aimed for tier4) from KDialog to QDialog Kevin Ottens


DONE Port from KGlobalSettings::desktopGeometry to QApplication::desktop()->screenGeometry (very easy) Stephen Kelly


DONE extract KProtocolInfo out of ksycoca, making it simply read from installed files on demand. (normal) David Faure


DONE move KProtocolInfo to KIO, requires to split out its unittests from kmimetypetest, and to somehow sort out the call to KProtocolInfo inside kmimetype (normal) David Faure


DONE when gpgmepp is not found, make plasma only skip the Signature class, rather than skipping all of plasma (easy) David Faure


DONE One of the things we need to remove is all of the use of the Q_WS_* defines. (easy)

git grep Q_WS_

Some of them should be ported to a Q_OS_ define (eg, some of Q_WS_WIN should be ported to Q_OS_WIN), but *not all of them*, so this can't just be changed with a script. It should be done manually. Some of them need to be ported to QPA (lighthouse) in some way.

Kevin Ottens


For a walk through example, see this thread

DONE Another thing that should be done is using Find packages from ECM or CMake. (normal)

For example, run 'git grep find_package' in tier1/solid. Some of the results are provided by CMake, and some come from the local kdelibs/cmake/modules folder. The kdelibs/cmake/modules folder should not need to be used. For example find_package(Flex) in solid should be replaced with find_package(FLEX) which is provided by CMake.

The goal is to be able to run

cd tier1/solid && mkdir build && cd build && cmake .. && make

for each framework.

This is already possible with the itemmodels framework.

It also works with solid, because the packages it searches for are optional and the FindFoo.cmake files are not found.

George Goldberg (grundleborg)

Frameworks Done:

  • tier1/itemmodels (except for autotests)
  • tier1/karchive
  • tier1/kcodecs
  • tier1/kcoreaddons
  • tier1/kdbusaddons
  • tier1/kideltime
  • tier1/kjs (*)
  • tier1/kplotting
  • tier1/kwidgetsaddons
  • tier1/kwindowsystem
  • tier1/solid (*)
  • tier1/sonnet (*)
  • tier1/threadweaver
  • tier2/kauth (*)
  • tier2/kconfig has problems building. need to resolve these first.

(*) Means that there are still FindFOO.cmake files in the framework's directory.

Kévin Ottens


DONE Port all of kdelibs from KIcon to QIcon / KDE:::icon(), then move KIcon out (easy) David Faure


DONE Port all uses of time_t to QDateTime (or qint64 when serializing). Ignore kdecore and karchive, other people are reworking these bits anyway. David Gil


DONE Make use of qplatformdefs.h definitions instead of using the POSIX versions directly. Aurélien Gâteau (Away until September, feel free to take over this task if necessary) --Taken over by Martin Klapetek
DONE Partly revert commit b03e81a61311ae1b64b0d37415477f9c08fe6142 which ported KFileItem to QFile::Permissions. Quoting David Faure:

"Port back from QFile::Permissions to mode_t given that mode_t is available in win32-msvc*/qplatformdefs.h

(not everywhere, but in the places where the above commits did a half job at porting from mode_t to QFile::Permissions).

QFile::Permissions is more limited (no suid bits) and having to convert between mode_t and QFile::Permissions is just extra work." https://git.reviewboard.kde.org/r/112481/

Aurélien Gâteau


DONE KGlobalSettings is initalized by KApplication. Find out if any parts of it work without that, and split it into parts that work without the initialization and parts that don't.

Conclusion: Let's just bury KGlobalSettings 10m underground. https://git.reviewboard.kde.org/r/111348/

https://git.reviewboard.kde.org/r/111298/

[email protected]


DONE Make KLocalizedString::isApplicationTranslatedInto and QLocale::uiLanguages codes compatible. See https://git.reviewboard.kde.org/r/111178 Vishesh Handa


DONE KDocTools needs to use tr to remove KI18n dependency Kevin Ottens

DONE Add helper code to Sonnet to make it easy to install on a QTextEdit Aurélien Gâteau
DONE Refactor KTextEdit to use Sonnet::TextEditDecorator, to avoid code duplication David Edmundson


DONE KStyle 1/3: Copy KStyle as K4Style in KDE4Support https://git.reviewboard.kde.org/r/112217 [email protected]
DONE KStyle 2/3: Remove everything from KStyle which is not a reimplementation of the following methods: polish, unpolish, eventFilter, styleHint, pixelMetrics, standardIcons https://git.reviewboard.kde.org/r/112519/ [email protected]
DONE KStyle 3/3: From what remains of KStyle after the previous two tasks, evaluate what is here to enforce platform settings and what might make style developers life too hard, keep only the parts about platform settings and let go the rest (this work should be coordinated with Hugo Pereira Da Costa) [email protected]


DONE Port kmimetypechooser.cpp from KRun to QProcess, then move it to a widgets framework that can use KConfig+KCoreAddons (but not kiowidgets, it doesn't use kio) Vishesh Handa


DONE Check if KScanDialog is still used. If not, deprecated. If yes, move to a framework that can use KService and KPageDialog, but not kiowidgets, it doesn't use kio Àlex Fiestas
DONE Remove KTextEditSpellInterface. See TODOs inside ktextedit.h Martin Sandsmark https://git.reviewboard.kde.org/r/113578/
DONE Update QCommandLineParser from the version that landed in qtbase dev and fix compilation (including plasma-framework). At least one thing changed, positionalArguments() and addHelpOption(str) is now setApplicationDescription(str)+addHelpOption(). Please do this before QCommandLineParser reaches qt5.git, or we'll be in trouble. Martin Gräßlin
DONE Port KJob to QEventLoopLocker. This provides the replacement of KGlobal::{de,}ref() Albert Astal Cid, committed by Aurélien Gâteau
DONE Port kfile/ from NetAccess to exec(). Then move NetAccess to kde4support, after ensuring all methods are documented as deprecated with a replacement solution (ask David if you don't find the replacement). Àlex Fiestas
DONE Move find_packages() from kdelibs/CMakeLists.txt to kdelibs/$tier/$framework/CMakeLists.txt: Aleix Pol
DONE Remove all links to libkdeqt5staging, since QCommandLineParser is in Qt https://git.reviewboard.kde.org/r/112557/ [email protected]
DONE All uses of NOGUI should be ported to ecm_mark_nongui_executable() -- Not as simple as it sound: real test on Windows and Mac OS is required to decide what is the best behavior. Aleix Pol
DONE Figure out forward includes, moving them to kde4support and finding an automated alternative for the modules Aleix Pol
DONE Figure out a replacement for KF5/Qt5 for KLocale::formatByteSize and KLocale::formatDuration

Suggested steps:

  • The obviously place to move it is k18n, as either part of

KLocalizedString or in a new KByteFormatter class?

  • Move KLocale::BinarySizeUnits, KLocale::BinaryUnitDialect, and

KLocale::formatByteSize()

  • Do we make it a pure static method? Or require an instance to be created?
  • If static-only then don't need setBinaryUnitDialect(), and

binaryUnitDialect() will become a static defaultBinaryUnitDialect() (There currently are no users of setBinaryUnitDialect, according to LXR)

  • No locale file overrides the default BinaryUnitDialect, so we only

have to worry about reading any user override from kglobals

  • Default to using QLocale() for number formatting, but need to be

able to set a different locale to use. If static-only then just add an extra parameter to override the locale, otherwise will need a setLocale()

  • Don't forget the tests :-)
John Layt
DONE Test all KDirWatch backends

The todo is probably

  • Let kdirwatch honour a environment variable like KDIRWATCH_METHOD for backend selection -- done by dfaure
  • Modify the current test to run multiple times with different values of said variable
  • Fix the code to get the tests to pass

the two first are probably much easier than the third

Current state is that inotify backend passes all tests and is the default on linux and only available on linux. QFSW-backend is the only available on windows and fails similar on both linux and windows. The stat and fam backends aren't tested anywhere.

DONE Clean up imageformat plugins in KGuiAddons: there are broken plugins, and no easy way to test them Alex Merry <[email protected]>
