Pointer Changes</h1>

|

<p>The February 2002 change to the Boost smart pointers introduced a number
|
||||
of changes. Since the previous version of the smart pointers was in use for
|

a long time, it's useful to have a detailed list of what changed from a library

user's point of view.</p>

<p>Note that for compilers that don't support member templates well enough,

a separate implementation is used that lacks many of the new features and is

more like the old version.</p>

|

<h2>Features Requiring Code Changes to Take Advantage</h2>
|

|

<ul>

header now includes the headers for the four classic smart pointer class templates.</li>
|

|
||||
<li>The <b>weak_ptr</b> template was added.</li>
|
||||
|

<li>The new <b>shared_ptr</b> and <b>shared_array</b> relax the requirement that the pointed-to object's

destructor must be visible when instantiating the <b>shared_ptr</b> destructor.
|

This makes it easier to have shared_ptr members in classes without explicit destructors.</li>
|
||||
|

<li>A custom deallocator can be passed in when creating a <b>shared_ptr</b> or <b>shared_array</b>.</li>
|
||||
|

<li><b>shared_static_cast</b> and <b>shared_dynamic_cast</b> function templates are

provided which work for <b>shared_ptr</b> and <b>weak_ptr</b> as <b>static_cast</b> and

<b>dynamic_cast</b> do for pointers.</li>
|
||||
|
||||
<li>The self-assignment misfeature has been removed from <b>shared_ptr::reset</b>,
|
||||
although it is still present in <b>scoped_ptr</b>, and in <b>std::auto_ptr</b>.
|
||||
Calling <b>reset</b> with a pointer to the object that's already owned by the

<b>shared_ptr</b> results in undefined behavior

|

file for details</li>
|
||||
|

<li>The new shared_ptr will always delete the object using the pointer it was originally constructed with.
|
||||
This prevents subtle problems that could happen if the last <b>shared_ptr</b> was a pointer to a sub-object
|

of a class that did not have a virtual destructor.</li>

<h2>Implementation Details</h2>
|

|

<ul>
|

<li>Some bugs in the assignment operator implementations and in <b>reset</b>

have been fixed by using the "copy and swap" idiom.</li>

// Effects: Atomically increments the value of a

// --a;
|

//
|

// Effects: Atomically decrements the value of a

// Returns: (long) zero if the new value of a is zero,
|

// unspecified non-zero value otherwise (usually the new value)
|
||||
//
|
||||
// Important note: when --a returns zero, it must act as a
|
||||
// read memory barrier (RMB); i.e. the calling thread must
|
||||
// have a synchronized view of the memory
|
||||
//
|
||||
// On Intel IA-32 (x86) memory is always synchronized, so this
|
||||
// is not a problem.
|
||||
//
|
||||
// On many architectures the atomic instructions already act as
|
||||
// a memory barrier.
|
||||
//
|
||||
// This property is necessary for proper reference counting, since
|
||||
// a thread can update the contents of a shared object, then
|
||||
// release its reference, and another thread may immediately
|
||||
// release the last reference causing object destruction.
|
||||
//
|
||||
// The destructor needs to have a synchronized view of the
|
||||
// object to perform proper cleanup.
|
||||
//
|
||||
// Original example by Alexander Terekhov:
|
||||
//
|
||||
// Given:
|
||||
//
|
||||
// - a mutable shared object OBJ;
|
||||
// - two threads THREAD1 and THREAD2 each holding
|
||||
// a private smart_ptr object pointing to that OBJ.
|
||||
//
|
||||
// t1: THREAD1 updates OBJ (thread-safe via some synchronization)
|
||||
// and a few cycles later (after "unlock") destroys smart_ptr;
|
||||
//
|
||||
// t2: THREAD2 destroys smart_ptr WITHOUT doing any synchronization
|
||||
// with respect to shared mutable object OBJ; OBJ destructors
|
||||
// are called driven by smart_ptr interface...

// - two threads THREAD1 and THREAD2 each holding

// a private smart_ptr object pointing to that OBJ.

//
|
||||
// t1: THREAD1 updates OBJ (thread-safe via some synchronization)
|
||||
// and a few cycles later (after "unlock") destroys smart_ptr;
|
||||
//
|
||||
// t2: THREAD2 destroys smart_ptr WITHOUT doing any synchronization
|
||||
// with respect to shared mutable object OBJ; OBJ destructors
|
||||
// are called driven by smart_ptr interface...

<h2><a name="Introduction">Introduction</a></h2>
|
||||
<p>Consistent use of <a href="shared_ptr.htm"><code>shared_ptr</code></a>
|
||||
can eliminate the need to use an explicit <code>delete</code>,
|
||||
but alone it provides no support in avoiding explicit <code>new</code>.
|
||||
There have been repeated requests from users for a factory function that creates
|
||||
an object of a given type and returns a <code>shared_ptr</code> to it.
|
||||
Besides convenience and style, such a function is also exception safe and
|
||||
considerably faster because it can use a single allocation for both the object
|
||||
and its corresponding control block, eliminating a significant portion of
|
||||
<code>shared_ptr</code>'s construction overhead.
|
||||
This eliminates one of the major efficiency complaints about <code>shared_ptr</code>.
|
||||
</p>
|
||||
<p>The header file <boost/make_shared.hpp> provides a family of overloaded function templates,
|
||||
<code>make_shared</code> and <code>allocate_shared</code>, to address this need.
|
||||
<code>make_shared</code> uses the global operator <code>new</code> to allocate memory,
|
||||
whereas <code>allocate_shared</code> uses an user-supplied allocator, allowing finer control.</p>
|
||||
<p>
|
||||
The rationale for choosing the name <code>make_shared</code> is that the expression
|
||||
<code>make_shared<Widget>()</code> can be read aloud and conveys the intended meaning.</p>

The copy constructor and destructor of <code>A</code> shall not throw.</p>
|

<p><b>Effects:</b> Allocates memory suitable for an object of type <code>T</code>
|
||||
and constructs an object in it via the placement new expression <code>new( pv ) T()</code>
|
||||
or <code>new( pv ) T( std::forward<Args>(args)... )</code>.
|
||||
<code>allocate_shared</code> uses a copy of <code>a</code> to allocate memory.
|
||||
If an exception is thrown, has no effect.</p>
|
||||
<p><b>Returns:</b> A <code>shared_ptr</code> instance that stores and owns the address
|
||||
of the newly constructed object of type <code>T</code>.</p>
|
||||
<p><b>Postconditions:</b> <code>get() != 0 && use_count() == 1</code>.</p>
|
||||
<p><b>Throws:</b> <code>bad_alloc</code>, or an exception thrown from <code>A::allocate</code>
|
||||
or the constructor of <code>T</code>.</p>
|
||||
<p><b>Notes:</b> This implementation allocates the memory required for the
|
||||
returned <code>shared_ptr</code> and an object of type <code>T</code> in a single
|
||||
allocation. This provides efficiency equivalent to an intrusive smart pointer.</p>
|
||||
<p>The prototypes shown above are used if your compiler supports rvalue references
|
||||
and variadic templates. They perfectly forward the <code>args</code> parameters to
|
||||
the constructors of <code>T</code>.</p>
|
||||
<p>Otherwise, the implementation will fall back on
|
||||
forwarding the arguments to the constructors of <code>T</code> as const references.
|
||||
If you need to pass a non-const reference to a constructor of <code>T</code>,
|
||||
you may do so by wrapping the parameter in a call to <code>boost::ref</code>.
|
||||
In addition, you will be
|
||||
limited to a maximum of 9 arguments (not counting the allocator argument of
|
||||
allocate_shared).</p>

<h1><IMG height="86" alt="C++ Boost" src="../../boost.png" width="277" align="middle" border="0">Pointer
|

cast functions</h1>
|
||||
<p>The pointer cast functions (<code>boost::static_pointer_cast</code> <code>boost::dynamic_pointer_cast</code>
|
||||
<code>boost::reinterpret_pointer_cast</code> <code>boost::const_pointer_cast</code>)
|
||||
provide a way to write generic pointer castings for raw pointers. The functions
|
||||
are defined in <CITE><A href="../../boost/pointer_cast.hpp">boost/pointer_cast.hpp</A>.</CITE></p>
|
||||
<P>There is test/example code in <CITE><A href="test/pointer_cast_test.cpp">pointer_cast_test.cpp</A></CITE>.</p>
|
||||
<h2><a name="rationale">Rationale</a></h2>
|
||||
<P>Boost smart pointers usually overload those functions to provide a mechanism to
|
||||
emulate pointers casts. For example, <code>boost::shared_ptr<...></code> implements
|
||||
a static pointer cast this way:</P>
|
||||
<pre>
|
||||
template<class T, class U>
|
||||
shared_ptr<T> static_pointer_cast(shared_ptr<U> const &r);
|
||||
</pre>
|
||||
<P>Pointer cast functions from <CITE><A href="../../boost/pointer_cast.hpp">boost/pointer_cast.hpp</A></CITE>
|
||||
are overloads of <code>boost::static_pointer_cast</code>, <code>boost::dynamic_pointer_cast</code>,
|
||||
<code>boost::reinterpret_pointer_cast</code> and <code>boost::const_pointer_cast</code>
|
||||
for raw pointers. This way when developing pointer type independent classes,
|
||||
for example, memory managers or shared memory compatible classes, the same code
|
||||
can be used for raw and smart pointers.</p>

<p>When building pointer independent classes, like memory managers, allocators, or

containers, there is often a need to define pointers generically, so that if a
|
||||
template parameter represents a pointer (for example, a raw or smart pointer to
|
||||
an int), we can define another pointer of the same type to another pointee (a
|
||||
raw or smart pointer to a float.)</p>
