Status
------

This change has been marked as submitted.


Review request for KDE Frameworks and Christoph Feck.


Changes
-------

Submitted with commit 757afa83ac74c51421cf16bcc44d53623bcfa908 by David Faure to branch master.


Repository: kiconthemes


Description
-------

In the first pass, we already checked whether the icon exists in all icon themes.
So in the second pass, there's no point in starting with that again, we can go
ahead and start doing fallbacks right away.

(The comment about the two passes was removed in b84858c, but some of it still
applies.)

Tested with: strace -e file ./kiconengine_unittest testUnknownIconNotCached |& wc -l
Before: 6341
After: 4589

Diff: https://git.reviewboard.kde.org/r/128514/diff/


Testing
-------

strace as mentionned above.

All unittests still pass (incl fallback lookups, didn't check how complete those were, though)


Thanks,

David Faure
