no - unlikely unless we got to lots of effort to make the c api threadsafe. most of efl is not threadsafe. only eina and eet are, with ecore (some of it) optionally. since bob will interface directly to evas - thus evas's api would need to be threadsafe for bob to be threadafe and... we're not likely doing this. marshall all your bob calls back to the mainloop and do them there. we have plenty of infra for just that without any locks. > 2013/12/16 Carsten Haitzler <ras...@rasterman.com> > > > On Mon, 16 Dec 2013 06:25:54 +0100 Thanatermesis < > > thanatermesis.e...@gmail.com> > > said: > > > > > > slight problem is that in the process of ensuring edje does > > > > its job, the over-engineering made it look like something different, > > and > > > that > > > > is where suddenly it looks bad because people use it as "something > > > different" > > > > then find all the creaky edge cases. > > > > > > Can you tell me which "creaky edge cases" ?
