 [section Revision History]

+[section Changes in 1.85.0]
+
+* Added a new [link core.functor `boost/core/functor.hpp`] header with a `functor` class template
+  for wrapping a raw function into a function object class.
+* Changed [link core.null_deleter `null_deleter`], [link core.fclose_deleter `fclose_deleter`]
+  and [link.checked_delete checked deleter] definitions so that they don't bring namespace `boost`
+  into argument-dependent lookup in cases like this:
+  ```
+  std::unique_ptr< std::FILE, boost::fclose_deleter > p1, p2;
+  swap(p1, p2); // no longer looks for boost::swap as part of ADL
+  ```
+  Users may need to either explicitly qualify the namespace of the called function or add a
+  `using`-declaration.

+* `boost::swap` utility function has been renamed to `boost::core::invoke_swap` to
+  avoid forming a potential infinite recursion when the arguments are not swappable.
+  The new function is defined in `boost/core/invoke_swap.hpp` and is functionally equivalent
+  to `boost::swap`. The old `boost::swap` name is preserved for backward compatibility
+  but deprecated and will be removed in a future release. Its `noexcept` specification
+  has been removed to avoid compile errors caused by compile-time recursion.
+  `BOOST_ALLOW_DEPRECATED_SYMBOLS` or `BOOST_ALLOW_DEPRECATED` can be defined to suppress
+  deprecation warnings for the transition period. ([@https://github.com/boostorg/core/issues/148 #148])
+* Headers `boost/swap.hpp`, `boost/utility/swap.hpp` and `boost/core/swap.hpp` are
+  deprecated and will be removed. Please, switch to `boost/core/invoke_swap.hpp`.
+  `BOOST_ALLOW_DEPRECATED_HEADERS` or `BOOST_ALLOW_DEPRECATED` can be defined to suppress
+  deprecation warnings.

+[section:functor functor]
+
+[simplesect Authors]
+
+* Andrey Semashev
+
+[endsimplesect]
+
+[section Header <boost/core/functor.hpp>]
+
+[note This component requires a compiler supporting C++17 or newer.]
+
+The header `<boost/core/functor.hpp>` defines the `boost::core::functor` class template
+that wraps a raw function specified in its template parameter into a function object class.
+The function object forwards any arguments passed to it to the wrapped function and returns
+the result of the call.
+
+The `functor` wrapper can be useful in cases when a function object class type is required,
+for example, for use with smart pointers such as `std::unique_ptr`, where the actual logic
+of the function object is already implemented as a raw function, possibly provided by a
+third party library. Since `functor` is default-constructible and does not store a pointer
+to the wrapped function internally, using `functor` is less error-prone and more efficient
+than using the pointer to function instead. For example, with `std::unique_ptr` you don't
+need to pass a pointer to the deleter function in the `std::unique_ptr` constructor, and
+the `std::unique_ptr` object does not store and invoke a pointer to the deleter function.
+With `functor`, the deleter function becomes part of the `std::unique_ptr` type, which
+prevents mixing pointers with incompatible deleters.
+
+```
+void my_deleter(void* p);
+
+using malloc_ptr = std::unique_ptr< char, boost::core::functor< std::free > >;
+using my_ptr = std::unique_ptr< char, boost::core::functor< my_deleter > >;
+
+my_ptr create_string(std::size_t size);
+void consume_string(my_ptr&& str);
+
+malloc_ptr ptr1(static_cast< char* >(std::malloc(size)));
+// ptr1 = allocate_string(size); // error, cannot convert my_ptr to malloc_ptr
+my_ptr ptr2 = create_string(size); // ok
+
+// consume_string(std::move(ptr1)); // error, cannot convert malloc_ptr&& to my_ptr
+consume_string(std::move(ptr2)); // ok
+```
+
+Using `functor` may also be beneficial for reducing generated code sizes. For example, in
+order to avoid storing and invoking a pointer to the deleter function in `std::shared_ptr`,
+one may be inclined to use lambda functions to wrap the deleter function call like this:
+
+```
+std::shared_ptr< int > ptr(static_cast< int* >(std::malloc(sizeof(int))), [](int* p) { std::free(p); });
+```
+
+The problem is that every lambda function declaration introduces a unique type, even if
+the lambda function definition matches exactly one of the previously declared lambda
+functions. Thus, if `std::shared_ptr` objects like the one above are created in multiple
+places in the program, the definition of the shared pointer counter and associated code
+and data (e.g. virtual function table) will be duplicated for each instance.
+
+Replacing the lambda function with `functor` solves this problem without sacrificing
+readability or efficiency:
+
+```
+std::shared_ptr< int > ptr(static_cast< int* >(std::malloc(sizeof(int))), boost::core::functor< std::free >());
+```
+

+
+[section Overview]
+
+The header <boost/core/pointer_in_range.hpp> provides the function template
+`boost::pointer_in_range` to check if a pointer is in a given range. This
+can be used in constant expressions in C++14 or higher when the compiler has a
+builtin to support `std::is_constant_evaluated`.
+
+[endsect]
+
+[section Examples]
+
+The following is an example of an allocator's deallocation function that does
+nothing if the pointer falls within a small automatically allocated buffer.
+
+```
+template<class T, class N>
+void
+Allocator<T, N>::deallocate(pointer ptr, size_type)
+{
+    if (!boost::pointer_in_range(ptr, &buffer_[0], &buffer_[N])) {
+        ::operator delete(ptr);
+    }
+}
+```

 // Note: the implementation of this utility contains various workarounds:

-// recursion (causing stack overflow) when swapping objects of a primitive
-// type.
-// - std::swap is imported with a using-directive, rather than
-// a using-declaration, because some compilers (including MSVC 7.1,
-// Borland 5.9.3, and Intel 8.1) don't do argument-dependent lookup
-// when it has a using-declaration instead.
 // - boost::swap has two template arguments, instead of one, to
 // avoid ambiguity when swapping objects of a Boost type that does

Andrey Semashev	ccfee3f638	Switch posix-cmake-test to use Ninja instead of Makefiles. This is yet another workaround for hanging posix-cmake-test on Mac OS. This enables parallel builds again, but uses Ninja build system instead of Makefiles. Enabling parallel builds speeds up the build process and releases Mac OS builders for other jobs sooner. Additionally, fix incorrect apt invocations in CMake-related jobs. apt is supposed to be used in interactive shells, and in scripts apt-get is recommended. Also, apt-get update is needed before apt install, and matrix.install must be transformed to a space-separated list. Also added retries on network errors.	2024-02-06 14:16:34 +03:00

Andrey Semashev	ce20d15048	Fix posix-cmake-test failures on Mac OS. Properly set BUILD_JOBS environment variable in CMake-related jobs as it is used in build and run steps. Without the variable being set, -j without a number means "no limit on the number of jobs", which may hit system resource limits and cause the job to fail. Also, Mac OS seem to sometimes hang on too many parallel build jobs, even if BUILD_JOBS is specified correctly. So disable parallel builds for now. Additionally, use GIT_FETCH_JOBS universally.	2024-02-06 06:06:49 +03:00

Andrey Semashev	95f0b35c36	Move fclose_deleter and null_deleter to their own namespaces to block ADL. This prevents bringing namespace boost into ADL when the deleters are used in template parameters, e.g. in std::unique_ptr.	2024-02-02 05:17:19 +03:00
Andrey Semashev	7b1d3718c1	Merge pull request #161 from boostorg/feature/functor Add `functor`	2024-01-27 19:34:21 +03:00
Andrey Semashev	80e12e1116	Added a new boost/core/functor.hpp header. The feader defines a new functor class template that can be used to wrap raw functions into a function object class. This is useful, for example, for integrating std::unique_ptr and unique_resource with custom deleters implemented as raw functions (e.g. in C libraries).	2024-01-26 20:51:02 +03:00

Andrey Semashev	9fc2a2f1ac	Renamed boost::swap to boost::core::invoke_swap, deprecated boost::swap. The rename allows to avoid forming an infinite recursion in compile time (because of noexcept specification that needs to resolve the unqualified call to swap) or run time (in case if the boost::swap function is the only one suitable for the passed arguments). To avoid the compile-time recursion, removed noexcept specification from boost::swap. The specification is still present in boost::core::invoke_swap. Deprecated boost::swap and associated headers. boost::core::invoke_swap is defined in a new boost/core/invoke_swap.hpp header. Updated docs and tests. Removed tests that check inclusion of deprecated headers. Fixes https://github.com/boostorg/core/issues/148.	2023-07-12 12:17:07 +03:00
