Milestone: To Be Determined → Boost 1.50.0
Status: new → assigned
Version: Boost 1.48.0 → Boost 1.49.0

Of course, I only haven't because I hadn't noticed that it was added. Which is a pity, as I think the specification has an off by one error. I've posted to comp.std.c++ about that, although maybe I'm wrong.

(In [78365]) Unordered: Implement reserve. Refs #6857.

Resolution: → fixed

(In [78432]) Unordered: Merge unordered from trunk.

  • Activate std::allocator_traits for gcc 4.7 and Visual C++ 11.
  • Implement variadic construct in boost::unordered::detail::allocator_traits when variadics, rvalue references and SFINAE expression are available.
  • Use variadic construct from allocator_traits, or when not available move the logic for constructing value_type to a lower level, so the container code is a bit simpler.
  • Avoid -Wshadow warnings. Fixes #6190.
  • Implement reserve. Fixes #6857.
