hi all, i am starting a new thread, because i want to start a new discussion on one aspect of boost.lockfree: the naming of the data structure and the interface naming: the current names of the data structures are fifo, stack and ringbuffer. during the pre-review some people suggested to use different names, lifo instead of stack or queue instead of fifo. in general i think it is a good idea to use a consistent naming (probably fifo should be renamed to queue), but how does the ringbuffer come in? it is a queue as well, but with different characteristics (spsc and wait-free). data structure configuration: stack and fifo currently use 3 template arguments: T for the managed type, freelist_t as a tag to select the underlying freelist and Alloc as the allocator which is used for the internal nodes: template<typename T, typename freelist_t = caching_freelist_t, typename Alloc = std::allocator<T> > class fifo/stack; however i have been thinking about replacing it with a boost.parameter interface, something like: template<typename T, ... Options> class fifo/stack; with the options: boost::lockfree::freelist_can_allocate<true/false> to disable memory allocation during enqueue/push boost::lockfree::allocator<> to specify the allocator ringbuffer size: the ringbuffer currently has the signature: template<typename T, size_t max_size> class ringbuffer; if max_size is 0, the size of the ringbuffer can be configured at run-time with a constructor. this is not really the cleanest interface, but i would like to provide an interface, which supports both compile-time and run-time setting of the size. i would apprechiate a discussion about these points during the review. thanks, tim
