Review request for Konsole and Kurt Hindenburg.


Repository: konsole


Description
-------

Use the new std::random APIs in c++11 for generating random numbers which is much safer and doesn't abuse qsrand().

This also means we don't need to copy in the QUuid::createUuid() code anymore, which generated a warning in ubsan.


Diffs (updated)
-----

  src/ColorScheme.cpp a85072b 
  src/Session.cpp 302bddc 

Diff: https://git.reviewboard.kde.org/r/129342/diff/


Testing (updated)
-------

It still generates random colors; all three HSV values are randomized properly and deterministically according to the randomSeed. Doesn't complain about Session::createUuid() anymore.


Thanks,

Martin Tobias Holmedahl Sandsmark
