Review request for KDE Frameworks, Christoph Feck and Volker Krause.


Repository: kiconthemes


Description
-------

This makes QIcon::fromTheme() much faster, for all cases where we have loaded the
icon once before (including in another process).

Diff: https://git.reviewboard.kde.org/r/124811/diff/


Testing
-------

The unittest has a way to see if KIconLoader used the cache or searched on disk, with the newly exported global int. I couldn't think of a better way.

I'll let Volker do the real-world testing and measure the overall impact as he did previously.


Thanks,

David Faure
