Review request for KDevelop.


Repository: kdev-qmljs


Description
-------

As pointed out by Sven Brauch, KStandardDirs::findResource can be slow (it has to access the file system). This patch caches in the parse session the top-level context of every referenced module. This way, when the user types and the same parse session is reused over and over again to update the DUChain, the filesystem is not touched.


Diffs
-----

  duchain/parsesession.h 0222d72 
  duchain/parsesession.cpp 798de10 

Diff: https://git.reviewboard.kde.org/r/118265/diff/


Testing
-------

All the unit tests still pass, and the behavior of import statements is as before (maybe a bit quicker, but it may be an impression).


Thanks,

Denis Steckelmacher
