The point is, the 'threads of execution' don't 'receive the message', as the 'slot()' methods are executed in the main thread. Right good point.
I think the signal's documentation should state that it has the basic thread safety, like one thread manipulating one signal is ok.
it isn't ok.
boost/function/function_template.hpp lines 653-659
template<typename Functor> void assign_to(Functor f) { static vtable_type stored_vtable(f); if (stored_vtable.assign_to(f, functor)) vtable = &stored_vtable; else vtable = 0; }
function static is not thread safe
This was not present in 1.33.1. If Boost.Function 1.33.1 is thread-safe but 1.34 is not, I would consider this as a *serious* regression. I know this could be a big change, but I strongly suggest that Boost.Function remains thread-safe in 1.34. PS: the vtable change comes from: revision 1.84, Fri Dec 30 02:31:51 2005 UTC. Tanguy
