* Remove move-only-type whitelists in CallbackParamTraits and CallbackForward ↵kinuko@chromium.org2013-10-221-32/+26

* Extend scoped_ptr to be closer to unique_ptr. Support custom deleters, and ↵ajwong@chromium.org2012-12-201-6/+6
| | | | | | | | | | | | | | | | | | | | | | | deleting arrays. This is based on the modifications by "Geoffrey Romer" <gromer@google.com> to Google's internal version of scoped_ptr<>. All cleaver tricks are his, not mine. :) It brings most of the features of C++11's unique_ptr<> into this class and should eliminate the need for scoped_array<>, scoped_malloc_free<>, and possibly a few other scopers. Please refer to the unique_ptr<> API for documentation. Divergence from unique_ptr<>: 1) DefaultDeleter<T[n]> (sized-arrays) is explicitly disabled because this construct would cause the single-object delete to be called on a pointer to a T[n]. It is impossible to construct a single-object new expression that returns a T[n]*. You can only get this with new[] which should correspond to DefaultDeleter<T[n][]>. This issue has been raised with the C++ LWG as it is possible a unique_ptr<> spec defect. 2) Reference types for Deleters are not supported. This simplifies implementation significantly because there is no need to distinguish between the converting constructor + converting assignment operator and their move constructor + move assignment operator. 4) Move-only Deleters are not supported. Avoids the need to emulate std::forward().

* Redo r113722 - Add Pass(), which implements move semantics, to scoped_ptr, ↵ajwong@chromium.org2011-12-221-0/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | scoped_array.... -- This time for sure. -- Add Pass(), which implements move semantics, to scoped_ptr, scoped_array, and scoped_ptr_malloc. This modification to the scopers implements the "moveable but not copyable" semantics that were introduced in C++11's unique_ptr<>. With this, is now possible to use scopers as an argument type or a return type. This signifies, in the type system, transfer of ownership into a function or out of a function respectively. Calling, or returning such a function MUST use the temporary resulting from a function or explicit cast. This distinction makes it possible to avoid the implicit ownership transfer issues of auto_ptr, but still allow us to have compiler enforced ownership transfer. Also adds a Passed() helper that allows using a scoper with Bind().

* Callback API Change: Reimplement Bind(); support IgnoreResult, full ↵ajwong@chromium.org2011-11-211-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | currying, and use less types. The main API change IgnoreResult() and fully currying. See unittest for what the new API looks like. The rest of the changes are done to support that. Previously, IgnoreReturn could not be used with WeakPtr<> Bind()s as it was applied after the fact to the Callback object. Now, IgnoreResult() wraps the function like Unretained(). As an incidental benefit, the new implementation gave us fully currying for free. Also, the new implementation scales better when supporting higher arities of functions. The new type growth is: (n^2 + 20n) / 2 as opposed to (3n^2 + 17n) / 2 where n == arity. For n = 6 and n=10, the new implementation has 81 and 155 templates respectively. The old implementation had 105 and 235 templates respectively.
