In view of the pending comittee meeting, and knowing those involved will be wanting to tie down any loose ends, I'm going to ask a thread-related question which relates as much to language support (I think) as boost thread, but this seems to be the active place for threads/ISO at the moment (please correct me if wrong)
I am going through our logging code again as we now have competing requirements and more rigorous requests for thread support. Currently our logging goes through a singleton implementation (provided by Andrei and the Loki library, thanks Andrei) but I would like to move to what I would describe as 'singleton-per-thread'. The neat thing about singletons (or at least this implementation) is that they exist for the lifetime of the process, potentially created before main and destructed only after main has exited. I would like a similar facility on a per-thread basis (tied to each thread's stack) This would allow me to log from multiple threads without having to lock the logger object, and without interspersing each threads messages throughout the same log. Is such an implementation possible with the current boost::thread, and is such an implementation currently under consideration in the lagnuage extension TR wrt thread support? It would seem 'obvious' to me that I would want to create each logger object in the stack of each thread, rather than as part of the parent thread object owned by the thread creating the child-thread. I also believe this logger example could quite easily be generalised to a whole group of designs that want per-thread 'singletons', but the logger makes a fairly clean example. -- AlisdairM Team Thai Kingdom _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
