Because I copied this template into 4 different files in KIO as well. It basically makes this bit of code reuseable elsewhere more easily (but this isn't big enough to be worth being put into Qt, especially since there is a slight variation between the cases where we need to be able to call hasLocalData from the outside, like here, and the cases in KIO where this is not needed and therefore the QThreadStorage instance can be moved into the function). I see your point that when reading just that file, the template thing looks surprising. grep KIO for perThreadGlobalStatic to see a pattern emerging, though... > On June 17, 2014, 4:50 p.m., Matthew Dawson wrote: > > src/core/ksharedconfig.cpp, line 72 > > <https://git.reviewboard.kde.org/r/118739/diff/1/?file=281111#file281111line72> > > > > Can you also please document the new behaviour of openConfig, that each > > instance is thread specific? Very good point.

KConfig already syncs in the destructor. For secondary threads, it should therefore already happen automatically, and this code takes care of the main thread explicitly. So I'm not sure what you see as missing here. - David ----------------------------------------------------------- This is an automatically generated e-mail.
