Currently, the WeakPointerTo comparison operators compare the raw pointers, but this is not useful as it may cause a false equality if one weak pointer in the comparison is expired and points to memory that has since been reused.
Instead, we can define a comparison based on the control block pointer, which exists since the new weak pointer implementation in 0bb81a43c9. This is implemented in the owner_before method, matching C++11 std::weak_ptr semantics.
I would now recommend deprecating most comparison operators of WeakPointerTo or redefining them to make more sense, ie. comparing equal if they (once) referred to the same object and not if they simply point to the same memory address. This has not yet been done, though code that uses the comparison operators has been fixed in this commit.
Overloads of std::owner_less have been provided for creating a map or set with Weak(Const)PointerTo keys.
As of f69354d9fa, this is just always
expected on all platforms. If it's not defined,
TemplateClass<X>::_type_handle won't link correctly with some compilers
(e.g. Clang) and the lack of 'extern template class' will result in
duplicated code in any case. In short, turning it off causes problems.
makepanda also always turns this on, so it doesn't represent any
optional feature or autodetected platform-specific behavior anyway.
Work around bugs in Apple Clang that ships with XCode 4 with C++11 by disabling constexpr
Use move() instead of std::move()
It also looks like we'll have to continue using pystub for tools that use libp3interrogatedb for now.
* Support trailing return type.
* Ignore C++14 digit separators.
* Parse C++14 binary number representations.
* Support "using"-style type aliases.
* Support decltype and auto with "new".
* Remove silly "long float" and "long long float".
* Support default visibility with class inheritance.
* Remove -longlong hack since C++11 supports long long natively.
* Support unary plus operator.
* Preserve bitfield definitions.
* Support constructor inits using braces.
* Support override/final specifiers.
* Ignore [[attributes]] in certain cases
* Add support for typeid() in expressions
* Parse (but ignore) lambda expressions
* Differentiate between casts, add const_cast/reinterpret_cast
* Support thread_local variables.
