Review request for Plasma and Aaron J. Seigo.


Repository: kdelibs


Description
-------

Fix 2 data races in runnercontext, mention another one.

Found by helgrinding krunner. Turns out helgrind lacks support for
QReadWriteLock, but reading the code still made me found these.


Diffs

  plasma/private/runnerjobs.cpp 6a8a7710f95adba38cc56c2d59393bfa3b123185 
  plasma/runnercontext.cpp abd6a4bc7fca2a0d05f27c6601b658ff552307b3 

Diff: https://git.reviewboard.kde.org/r/118896/diff/


Testing
-------

Typing various things into krunner.

The main crash is still there though: baloo or xapian isn't reentrant; but that's separate.


Thanks,

David Faure
