KDE Frameworks 5 and Plasma 2 co-installability

It should be possible to install a kde frameworks 5 runtime alonside a kdelibs 4 runtime so apps can use either one

Dependencies:

Qt libraries it depends on already have two versions with different sonames or different names

phonon - rename done
attica - rename done
dbusmenu - rename done
oxygen-icons - just install the latest version
qimageblitz - rename done
libstream and libstreamanalyzer - not qt libraries so ABI the same and no rename needed
grantlee - not ported to Qt 5 but it is only used for a test which is disabled.

KDE Frameworks 5

data files:

Most install into DATA_INSTALL_DIR which can be made version specific, e.g. /usr/share/kde4/ and /usr/share/kdeframeworks5

share/LICENSES/ DATA_INSTALL_DIR
share/kcharselect/kcharselect-data DATA_INSTALL_DIR
share/ksgmltools2 DATA_INSTALL_DIR
share/xmlgui/pics/aboutkde.png DATA_INSTALL_DIR
share/khtml/ DATA_INSTALL_DIR
share/kssl/ DATA_INSTALL_DIR
share/kconfigwidgets DATA_INSTALL_DIR (and changed dir name)
share/knewstuff/pics DATA_INSTALL_DIR
share/kconf_update DATA_INSTALL_DIR
share/kjava DATA_INSTALL_DIR
share/proxyscout/ DATA_INSTALL_DIR
share/kcm_componentchooser/ DATA_INSTALL_DIR
share/kdewidgets/ DATA_INSTALL_DIR

These are files which can be shared between kdelibs 4 and kde frameworks 5

share/locale/ can be shared
share/mime/packages/kde.xml can be shared
share/icons/hicolor/ - kimproxy icons can be shared
share/doc can be shared
etc/dbus-1/system.d/org.kde.auth.conf can be shared
etc/xdg/ can be shared

Some files are only needed for developers where the kdelibs and kdeframeworks packages can be made to conflict

share/dbus-1/interfaces/ dev files
share/kauth/ dev files and DATA_INSTALL_DIR
share/cmake/modules/ dev files and DATA_INSTALL_DIR

binaries:

Some are renamed already or a new:

bin/kdeinit5_shutdown
bin/kbuildsycoca5
bin/kdeinit5_wrapper
bin/meinproc5
bin/kdeinit5
bin/kf5-config
bin/kded5
bin/desktoptojson
bin/kshell5
bin/kwrapper5
bin/kcookiejar5 (arguably a developer only binary)

Some are developer only binaries, the -dev package can be muturally exclusive:

bin/makekdewidgets
bin/checkXML
bin/preparetips
bin/kconfig_compiler
bin/kjs
bin/kjscmd

Kross is probably unimportant enough to just swap for KF5 version, this can be used to run some non-GUI kross scripts

bin/kross

Some are interchangeable binaries:

bin/kmailservice
bin/ktelnetservice

libraries:

All libraries renamed and versoned to 5.0.0

set some cmake variables to keep various bits separate

plugins/ needs QT_PLUGIN_INSTALL_DIR set
lib/cmake needs CMAKECONFIG_INSTALL_DIR set
lib/qml/org/kde/solid/libsolidextensionplugin.so new file
libexec can be put in a kf5 directory with LIBEXEC_INSTALL_DIR

KActivities

kdelibs 4 and kde frameworks 5 versions are co-installable

developer files in include/ and lib/pkgconfig and lib/cmake/ will be mutually exclusive
plugins installed into plugins/kf5 to keep them separate
kactivities library has been renamed with capital letters and new SONAME
kactivitymanagerd can be shared between libkactivities in kde4 and in kf5, it has the same same dbus interface
share/ontologies/kao* can be shared

kde-runtime

Much of kde-runtime is yet to be ported

binaries

renamed binaries

kcmshell5

interchangeable binaries, packagers should use the version from kde sc 5 and drop the version from kde sc 4

kdecp
kdemv
kdeopen
kioclient
ktrash

plugins

kioexec set a separate LIBEXEC_INSTALL_DIR
plugins/kf5 set a separate PLUGIN_INSTALL_DIR

data files

jpegcreatorsettings.kcfg set a separate KCFG_INSTALL_DIR e.g. /usr/share/kf5/config.kcfg
kcmlocale/pics/background.png set a separate DATA_INSTALL_DIR
.desktop and .protocol files set SERVICES_INSTALL_DIR to e.g. /usr/share/kde5/services

developer files

org.kde.KTimeZoned.xml interface file, no longer installed https://git.reviewboard.kde.org/r/113819/

KDE Workspace

Not co-installable, the whole point is to have Plasma 2 and the workspace ported to KF5

KControl Modules

Various KControl modules in kde-runtime and kde-workspace need ported to KF5.

They will then edit files in the kf5 settings directory ~/.config/kf5 and not kde 4 settings. For some it might be useful to share settings, a symlink from e.g. ~/.kde/share/config/kdeglobals to ~/.config/kf5/kdeglobals may work if the config values are the same.
