Howard Hinnant 801291139c After sleeping on it I've decided that all special members that can be noexcept, should be declared so. The client has the traits to detect and branch on this information, and it is often an important optimization. Give deque() a noexcept. Add test for deque default constructor and deque destructor.

Howard Hinnant b58f59cdb3 Second try at getting noexcept on move and swap for deque. I changed std::alloctor to propagate_on_container_move_assignment so as to make deque<T> move assignment noexcept. What we really need is a compile-time switch that says an allocator always compares equal.

Howard Hinnant 9eebe11dd5 I've become quite disatsified with the lack of noexcept specifications on container move construction, move assignment operator and swap. Without proper decoration on at least move construction, vectors of containers will have unacceptable performance. Here's the fix for deque.

Howard Hinnant bc95cf0d5f Experimental support for a meaningful __is_swappable<T>::value. This does not appear to be strictly needed for correct functioning of the library. If it causes any problems, I'd rather pull it sooner rather than later.

Howard Hinnant 3739fe79e5 noexcept for <memory>. I've added a few extension noexcept to: allocator_traits<A>::deallocate, allocaate<T>::deallocate, return_temporary_buffer, and default_delete<T>::operator()(T*) const. My rationale was: If a std-dicated noexcept function needs to call another std-defined function, that called function must be noexcept. We're all a little new to noexcept, so things like this are to be expected. Also included fix for broken __is_swappable trait pointed out by Marc Glisse, thanks Marc|. And fixed a test case for is_nothrow_destructible. Destructors are now noexcept by default|

Howard Hinnant 27d0a2a75d noexcept for <tuple>. And in the process learned that I had done it wrong for pair's swap. I needed to create an __is_nothrow_swappable<T>::value trait that was smart enought to answer false when __is_swappable<T>::value is false. Otherwise one gets compile-time errors when using pair or tuple of non-swappable types, even if you never try to swap the pair or tuple.

Howard Hinnant 5eb6bdfa1d __invokable and __invoke_of now check for incomplete types and issue a compile-time diagnostic if they are used with incomplete types for anything except a return type. Note that both arguments *and* parameters are checked for completeness.

 2011-05-22 00:09:02 +00:00
Howard Hinnant 6282a4a1d3 This is a simplified (and superior) implementation of __invoke, __invokable and __invoke_of. It is superior in that __invoke now handles reference qualified member functions whereas the previous implementation did not. And it simply has less infrastructure in its implementation. I'm still learning how to program in C++11 (and probably will be for a long time). This change does not impact the behavior we're seeing in http://llvm.org/bugs/show_bug.cgi?id=9975

Howard Hinnant ec0810e1c8 I had a giant misunderstanding of what 'synchronizes with' meant in [futures.async]/p5. This invalidated the current design of async in <future>. This is a new design, based on my new understanding, which has been confirmed on the lwg mailing list. The summary is that ~future() (and ~shared_future()) will block when they are created from within async, and the thread hasn't finished yet. As part of this work I created two new type traits: __invokable<F, Args...>::value and __invoke_of<F, Args...>::type. These are what result_of<F(Args...)> wanted to be when it grew up, but never will be. __invoke_of is carefully crafted so that it can serve as its own enable_if (type doesn't exist if the signature isn't invokable). All of this work is C++11 only.

Howard Hinnant 0c68ed006d Chris Jefferson spotted a problem with messages_base::catalog while getting libc++ to work on boost. The standard says this type must be an int. But this type is the key returned by the OS facility catopen. On OS X the type returned by catopen is void*, which doesn't fit into an int on 64 bit platforms. Chris suggested using ptrdiff_t instead of void*. It still isn't compliant with the standard, but chances are that this change will fix what is ailing boost. Chris also supplied the algorithm for distinguishing high-order pointers from error conditions. Thanks Chris.

Douglas Gregor 71711a673b Inline namespaces are always available in Clang. Rely on that without 
testing via __has_feature, since __has_feature for C++0x features no

Also, eliminate the redundant using directive. Inline namespaces make
their members visible in the enclosing namespace automatically.

Douglas Gregor a7b2241407 Eliminate the C++0x-only is_convertible testing function that accepts 
a cv-qualifier rvalue reference to the type, e.g.,

  template <class _Tp> char  __test(const volatile typename remove_reference<_Tp>::type&&);

The use of this function signature rather than the more
straightforward one used in C++98/03 mode, e.g.,

  template <class _Tp> char  __test(_Tp);

is broken in two ways:

  1) An rvalue reference cannot bind to lvalues, so is_convertible<X&,
  X&>::value would be false. This breaks two of the unique_ptr tests
  on Clang and GCC >= 4.5. Prior GCC's seem to have allowed rvalue
  references to bind to lvalues, allowing this bug to slip in.

  2) By adding cv-qualifiers to the type we're converting to, we get
  some incorrect "true" results for, e.g., is_convertible<const X&, X&>::value.

It currently won't even parse as it depends on the existence of the intrinsics specified at http://libcxx.llvm.org/atomic_design_a.html. Everything has been tested using fake intrinsics which have now been removed. As the intrinsics come online, the ATOMIC_* macros will need to be adjusted to reflect which operations are lock-free. These macros will probably need to be #ifdef'd for each supported platform.
