Review request for KDE Software on Mac OS X and KDE Frameworks.


Changes
-------

It's been a while!

This new version drops the possibility to launch from shared libraries on OS X, and thus no longer needs a launcher proxy. For now I've kept most of the code unchanged, meaning that kdeinit5 still forks before exec'ing the requested application. This is safe, so it has the advantage of following the regular Unix variant as closely as possible.

Tested against K5W 5.20.0, patch against git/head.


Repository: kinit


Description
-------

This patch addresses several issues with the OS X adaptations:

-1 replaces the obsolete Q_OS_MAC with Q_OS_OSX
-2 builds the relevant applications `nongui` instead of as app bundles
-3 turns klauncher into an "agent" by setting `LSUIElement` to true programmatically
-4 ports a patch that has been in MacPorts' `port:kdelibs4` since October 14th 2009, which prevents a kdeinit crash that is caused by calling exec after `fork()` in an application that has used non-POSIX APIs and/or calling those APIs in the exec'ed application. This patch (originally by MacPorts developers Jeremy Lainé and Jeremy Lavergne) rearranges call order and uses a proxy application to do the actual exec.

Testing
-------

On OS X 10.9.5 with Qt 5.5.1 and KF5rameworks 5.16.0 . With this patch, starting `kded5` will launch kdeinit5 and klauncher5 as expected, but `kdeinit5 --kded` does not yet launch `kded5`. This is probably acceptable for typical KF5 use on OS X (kded5 can be launched as a login item or as a LaunchAgent) but I will have another look at why the kded isn't started.

I am not yet able to perform further testing; practice will for instance have to show whether point 2 above needs revision (apps that need to be installed as app bundles).

Similarly it will have to be seen whether point 3 above has any drawbacks. Applications running as agents do not show up in the Dock or App Switcher. Thus, klauncher will not be able to "turn itself into" an application that does have a full GUI presence with my current modification. I don't know if that's supposed to be possible though.
NB: I have been building the KDE4 klauncher in a way that makes it impossible to construct a GUI at all, so I'm not expecting issues in KF5 as long as klauncher's role hasn't evolved too much.


Thanks,

René J.V. Bertin
