A tuple of the form {void*, + * size_t} specifies a mutable (modifiable) region of memory. Similarly, a + * tuple of the form {const void*, size_t} specifies a const + * (non-modifiable) region of memory. These two forms correspond to the classes + * mutable_buffer and const_buffer, respectively. To mirror C++'s conversion + * rules, a mutable_buffer is implicitly convertible to a const_buffer, and the + * opposite conversion is not permitted. + * + * The simplest use case involves reading or writing a single buffer of a + * specified size: + * + * @code sock.send(asio::buffer(data, size)); @endcode + * + * In the above example, the return value of asio::buffer meets the + * requirements of the ConstBufferSequence concept so that it may be directly + * passed to the socket's write function. A buffer created for modifiable + * memory also meets the requirements of the MutableBufferSequence concept. + * + * An individual buffer may be created from a builtin array, std::vector, + * std::array or boost::array of POD elements. This helps prevent buffer + * overruns by automatically determining the size of the buffer: + * + * @code char d1[128]; + * size_t bytes_transferred = sock.receive(asio::buffer(d1)); + * + * std::vector d2(128); + * bytes_transferred = sock.receive(asio::buffer(d2)); + * + * std::array d3; + * bytes_transferred = sock.receive(asio::buffer(d3)); + * + * boost::array d4; + * bytes_transferred = sock.receive(asio::buffer(d4)); @endcode + * + * In all three cases above, the buffers created are exactly 128 bytes long. + * Note that a vector is @e never automatically resized when creating or using + * a buffer. The buffer size is determined using the vector's size() + * member function, and not its capacity. + * + * @par Accessing Buffer Contents + * + * The contents of a buffer may be accessed using the @c data() and @c size() + * member functions: + * + * @code asio::mutable_buffer b1 = ...; + * std::size_t s1 = b1.size(); + * unsigned char* p1 = static_cast(b1.data()); + * + * asio::const_buffer b2 = ...; + * std::size_t s2 = b2.size(); + * const void* p2 = b2.data(); @endcode + * + * The @c data() member function permits violations of type safety, so + * uses of it in application code should be carefully considered. + * + * For convenience, a @ref buffer_size function is provided that works with + * both buffers and buffer sequences (that is, types meeting the + * ConstBufferSequence or MutableBufferSequence type requirements). In this + * case, the function returns the total size of all buffers in the sequence. + * + * @par Buffer Copying + * + * The @ref buffer_copy function may be used to copy raw bytes between + * individual buffers and buffer sequences. +* + * In particular, when used with the @ref buffer_size function, the @ref + * buffer_copy function can be used to linearise a sequence of buffers. For + * example: + * + * @code vector buffers = ...; + * + * vector data(asio::buffer_size(buffers)); + * asio::buffer_copy(asio::buffer(data), buffers); @endcode + * + * Note that @ref buffer_copy is implemented in terms of @c memcpy, and + * consequently it cannot be used to copy between overlapping memory regions. + * + * @par Buffer Invalidation + * + * A buffer object does not have any ownership of the memory it refers to. It + * is the responsibility of the application to ensure the memory region remains + * valid until it is no longer required for an I/O operation. When the memory + * is no longer available, the buffer is said to have been invalidated. + * + * For the asio::buffer overloads that accept an argument of type + * std::vector, the buffer objects returned are invalidated by any vector + * operation that also invalidates all references, pointers and iterators + * referring to the elements in the sequence (C++ Std, 23.2.4) + * + * For the asio::buffer overloads that accept an argument of type + * std::basic_string, the buffer objects returned are invalidated according to + * the rules defined for invalidation of references, pointers and iterators + * referring to elements of the sequence (C++ Std, 21.3). + * + * @par Buffer Arithmetic + * + * Buffer objects may be manipulated using simple arithmetic in a safe way + * which helps prevent buffer overruns. Consider an array initialised as + * follows: + * + * @code boost::array a = { 'a', 'b', 'c', 'd', 'e' }; @endcode + * + * A buffer object @c b1 created using: + * + * @code b1 = asio::buffer(a); @endcode + * + * represents the entire array, { 'a', 'b', 'c', 'd', 'e' }.

The + * class itself is used to store the current state of the coroutine. + * + * Coroutines are copy-constructible and assignable, and the space overhead is + * a single int. They can be used as a base class: + * + * @code class session : coroutine + * { + * ... + * }; @endcode + * + * or as a data member: + * + * @code class session + * { + * ... + * coroutine coro_; + * }; @endcode + * + * or even bound in as a function argument using lambdas or @c bind(). The + * important thing is that as the application maintains a copy of the object + * for as long as the coroutine must be kept alive. + * + * @par Pseudo-keywords + * + * A coroutine is used in conjunction with certain "pseudo-keywords", which + * are implemented as macros. These macros are defined by a header file: + * + * @code #include @endcode + * + * and may conversely be undefined as follows: + * + * @code #include @endcode + * + * reenter + * + * The @c reenter macro is used to define the body of a coroutine. It takes a + * single argument: a pointer or reference to a coroutine object. For example, + * if the base class is a coroutine object you may write: + * + * @code reenter (this) + * { + * ... coroutine body ... + * } @endcode + * + * and if a data member or other variable you can write: + * + * @code reenter (coro_) + * { + * ... coroutine body ... + * } @endcode + * + * When @c reenter is executed at runtime, control jumps to the location of the + * last @c yield or @c fork. + * + * The coroutine body may also be a single statement, such as: + * + * @code reenter (this) for (;;) + * { + * ... + * } @endcode + * + * @b Limitation: The @c reenter macro is implemented using a switch. This + * means that you must take care when using local variables within the + * coroutine body. The local variable is not allowed in a position where + * reentering the coroutine could bypass the variable definition. + * + * yield statement + * + * This form of the @c yield keyword is often used with asynchronous operations: + * + * @code yield socket_->async_read_some(buffer(*buffer_), *this); @endcode + * + * This divides into four logical steps: + * + * @li @c yield saves the current state of the coroutine. + * @li The statement initiates the asynchronous operation. + * @li The resume point is defined immediately following the statement. + * @li Control is transferred to the end of the coroutine body. + * + * When the asynchronous operation completes, the function object is invoked + * and @c reenter causes control to transfer to the resume point. It is + * important to remember to carry the coroutine state forward with the + * asynchronous operation. In the above snippet, the current class is a + * function object object with a coroutine object as base class or data member. + * + * The statement may also be a compound statement, and this permits us to + * define local variables with limited scope: + * + * @code yield + * { + * mutable_buffers_1 b = buffer(*buffer_); + * socket_->async_read_some(b, *this); + * } @endcode + * + * yield return expression ; + * + * This form of @c yield is often used in generators or coroutine-based parsers. + * For example, the function object: + * + * @code struct interleave : coroutine + * { + * istream& is1; + * istream& is2; + * char operator()(char c) + * { + * reenter (this) for (;;) + * { + * yield return is1.get(); + * yield return is2.get(); + * } + * } + * }; @endcode + * + * defines a trivial coroutine that interleaves the characters from two input + * streams. + * + * This type of @c yield divides into three logical steps: + * + * @li @c yield saves the current state of the coroutine. + * @li The resume point is defined immediately following the semicolon. + * @li The value of the expression is returned from the function. + * + * yield ; + * + * This form of @c yield is equivalent to the following steps: + * + * @li @c yield saves the current state of the coroutine. + * @li The resume point is defined immediately following the semicolon. + * @li Control is transferred to the end of the coroutine body. + * + * This form might be applied when coroutines are used for cooperative + * threading and scheduling is explicitly managed. For example: + * + * @code struct task : coroutine + * { + * ... + * void operator()() + * { + * reenter (this) + * { + * while (... not finished ...) + * { + * ... do something ... + * yield; + * ... do some more ... + * yield; + * } + * } + * } + * ... + * }; + * ... + * task t1, t2; + * for (;;) + * { + * t1(); + * t2(); + * } @endcode + * + * yield break ; + * + * The final form of @c yield is used to explicitly terminate the coroutine. + * This form is comprised of two steps: + * + * @li @c yield sets the coroutine state to indicate termination. + * @li Control is transferred to the end of the coroutine body. + * + * Once terminated, calls to is_complete() return true and the coroutine cannot + * be reentered. + * + * Note that a coroutine may also be implicitly terminated if the coroutine + * body is exited without a yield, e.g. by return, throw or by running to the + * end of the body. + * + * fork statement + * + * The @c fork pseudo-keyword is used when "forking" a coroutine, i.e. splitting + * it into two (or more) copies. One use of @c fork is in a server, where a new + * coroutine is created to handle each client connection: + * + * @code reenter (this) + * { + * do + * { + * socket_.reset(new tcp::socket(io_context_)); + * yield acceptor->async_accept(*socket_, *this); + * fork server(*this)(); + * } while (is_parent()); + * ... client-specific handling follows ... + * } @endcode + * + * The logical steps involved in a @c fork are: + * + * @li @c fork saves the current state of the coroutine. + * @li The statement creates a copy of the coroutine and either executes it + * immediately or schedules it for later execution. + * @li The resume point is defined immediately following the semicolon. + * @li For the "parent", control immediately continues from the next line. + * + * The functions is_parent() and is_child() can be used to differentiate + * between parent and child.

An @c io_context is an example of an execution context. + * + * @par The execution_context class and services + * + * Class execution_context implements an extensible, type-safe, polymorphic set + * of services, indexed by service type. + * + * Services exist to manage the resources that are shared across an execution + * context. For example, timers may be implemented in terms of a single timer + * queue, and this queue would be stored in a service. + * + * Access to the services of an execution_context is via three function + * templates, use_service(), add_service() and has_service(). + * + * In a call to @c use_service(), the type argument chooses a service, + * making available all members of the named type. If @c Service is not present + * in an execution_context, an object of type @c Service is created and added + * to the execution_context. A C++ program can check if an execution_context + * implements a particular service with the function template @c + * has_service(). + * + * Service objects may be explicitly added to an execution_context using the + * function template @c add_service(). If the @c Service is already + * present, the service_already_exists exception is thrown. If the owner of the + * service is not the same object as the execution_context parameter, the + * invalid_service_owner exception is thrown. + * + * Once a service reference is obtained from an execution_context object by + * calling use_service(), that reference remains usable as long as the owning + * execution_context object exists. + * + * All service implementations have execution_context::service as a public base + * class. Custom services may be implemented by deriving from this class and + * then added to an execution_context using the facilities described above. + * + * @par The execution_context as a base class + * + * Class execution_context may be used only as a base class for concrete + * execution context types. The @c io_context is an example of such a derived + * type. + * + * On destruction, a class that is derived from execution_context must perform + * execution_context::shutdown() followed by + * execution_context::destroy(). + * + * This destruction sequence permits programs to simplify their resource + * management by using @c shared_ptr<>. Where an object's lifetime is tied to + * the lifetime of a connection (or some other sequence of asynchronous + * operations), a @c shared_ptr to the object would be bound into the handlers + * for all asynchronous operations associated with it. This works as follows: + * + * @li When a single connection ends, all associated asynchronous operations + * complete. The corresponding handler objects are destroyed, and all @c + * shared_ptr references to the objects are destroyed. + * + * @li To shut down the whole program, the io_context function stop() is called + * to terminate any run() calls as soon as possible.

Calling restart() while there are unfinished run(), + * run_one(), poll() or poll_one() calls results in undefined behaviour. The + * notify_fork() function should not be called while any io_context function, + * or any function on an I/O object that is associated with the io_context, is + * being called in another thread. + * + * @par Concepts: + * Dispatcher. + * + * @par Synchronous and asynchronous operations + * + * Synchronous operations on I/O objects implicitly run the io_context object + * for an individual operation. The io_context functions run(), run_one(), + * poll() or poll_one() must be called for the io_context to perform + * asynchronous operations on behalf of a C++ program. Notification that an + * asynchronous operation has completed is delivered by invocation of the + * associated handler. Handlers are invoked only by a thread that is currently + * calling any overload of run(), run_one(), poll() or poll_one() for the + * io_context. + * + * @par Effect of exceptions thrown from handlers + * + * If an exception is thrown from a handler, the exception is allowed to + * propagate through the throwing thread's invocation of run(), run_one(), + * poll() or poll_one(). No other threads that are calling any of these + * functions are affected. It is then the responsibility of the application to + * catch the exception. + * + * After the exception has been caught, the run(), run_one(), poll() or + * poll_one() call may be restarted @em without the need for an intervening + * call to restart(). This allows the thread to rejoin the io_context object's + * thread pool without impacting any other threads in the pool. + * + * For example: + * + * @code + * asio::io_context io_context; + * ... + * for (;;) + * { + * try + * { + * io_context.run(); + * break; // run() exited normally + * } + * catch (my_exception& e) + * { + * // Deal with exception as appropriate. + * } + * } + * @endcode + * + * @par Stopping the io_context from running out of work + * + * Some applications may need to prevent an io_context object's run() call from + * returning when there is no more work to do. For example, the io_context may + * be being run in a background thread that is launched prior to the + * application's asynchronous operations. The run() call may be kept running by + * creating an object of type + * asio::executor_work_guard: + * + * @code asio::io_context io_context; + * asio::executor_work_guard + * = asio::make_work_guard(io_context); + * ... @endcode + * + * To effect a shutdown, the application will then need to call the io_context + * object's stop() member function. This will cause the io_context run() call + * to return as soon as possible, abandoning unfinished operations and without + * permitting ready handlers to be dispatched. + * + * Alternatively, if the application requires that all operations and handlers + * be allowed to finish normally, the work object may be explicitly reset. + * + * @code asio::io_context io_context; + * asio::executor_work_guard + * = asio::make_work_guard(io_context); + * ... + * work.reset(); // Allow run() to exit. @endcode + */ +class io_context + : public execution_context +{ +private: + typedef detail::io_context_impl impl_type; +#if defined(ASIO_HAS_IOCP) + friend class detail::win_iocp_overlapped_ptr; +#endif + +public: + class executor_type; + friend class executor_type; + +#if !defined(ASIO_NO_DEPRECATED) + class work; + friend class work; +#endif // !defined(ASIO_NO_DEPRECATED) + + class service; + +#if !defined(ASIO_NO_EXTENSIONS) + class strand; +#endif // !defined(ASIO_NO_EXTENSIONS) + + /// The type used to count the number of handlers executed by the context. + typedef std::size_t count_type; + + /// Constructor. + ASIO_DECL io_context(); + + /// Constructor. + /** + * Construct with a hint about the required level of concurrency. + * + * @param concurrency_hint A suggestion to the implementation on how many + * threads it should allow to run simultaneously. + */ + ASIO_DECL explicit io_context(int concurrency_hint); + + /// Destructor. + /** + * On destruction, the io_context performs the following sequence of + * operations: + * + * @li For each service object @c svc in the io_context set, in reverse order + * of the beginning of service object lifetime, performs + * @c svc->shutdown(). + * + * @li Uninvoked handler objects that were scheduled for deferred invocation + * on the io_context, or any associated strand, are destroyed. + * + * @li For each service object @c svc in the io_context set, in reverse order + * of the beginning of service object lifetime, performs + * delete static_cast(svc). + * + * @note The destruction sequence described above permits programs to + * simplify their resource management by using @c shared_ptr<>.

Free functions `dispatch()`, `post()` and `defer()` + have been added and are used to submit function objects to executors. + + * Completion handlers now have an associated executor and associated + allocator. The free function `wrap()` is used to associate an executor with + a handler or other object. The handler hooks for allocation, invocation and + continuation have been deprecated. + + * A `system_executor` class has been added as a default executor. + + * The `io_service` class is now derived from `execution_context` and + implements the executor type requirements in its nested `executor_type` + class. The member functions `dispatch()`, `post()`, `defer()` and `wrap()` + have been deprecated. The `io_service::work` class has been deprecated. + + * The `io_service` member function `reset()` has been renamed to `restart()`. + The old name is retained for backward compatibility but has been + deprecated. + + * The `make_service<>()` function is now used to add a new service to an + execution context such as an `io_service`. The `add_service()` function has + been deprecated. + + * A new `strand<>` template has been added to allow strand functionality to + be used with generic executor types. + + * I/O objects (such as sockets and timers) now provide access to their + associated `io_service` via a `context()` member function. The + `get_io_service()` member function is deprecated. + + * All asynchronous operations and executor operations now support move-only + handlers. However, the deprecated `io_service::post()`, + `io_service::dispatch()`, `io_service::strand::post()` and + `io_service::strand::dispatch()` functions still require copyable handlers. + + * Waitable timer objects are now movable. + + * Waitable timers, socket iostreams and socket streambufs now provide an + `expiry()` member function for obtaining the expiry time. The accessors + `expires_at()` and `expires_after()` have been deprecated, though those + names are retained for the mutating members. + + * The `std::packaged_task` class template is now supported as a completion + handler. The initiating operation automatically returns the future + associated with the task. The `package()` function has been added as a + convenient factory for packaged tasks. + + * Sockets, socket acceptors and descriptors now provide `wait()` and + `async_wait()` operations that may be used to wait for readiness. The + `null_buffers` type has been deprecated. + + * The proposed error code enum classes are simulated using namespaces. + Existing asio error codes now have a correspondence with the standard error + conditions. + + * Conversion between IP address types, and conversion from string to address, + is now supported via the `address_cast<>()`, `make_address()`, + `make_address_v4()` and `make_address_v6()` free functions. The + `from_string()`, `to_v4()`, `to_v6()` and `v4_mapped()` member functions + have been deprecated. + + * A default-constructed `ip::address` now represents an invalid address value + that is neither IPv4 nor IPv6. + + * New `buffer()` overloads that generate mutable buffers for non-const + `string` objects. + + * Support for dynamic buffer sequences that automatically grow and shrink to + accomodate data as it is read or written. This is a generic facility + similar to the existing `asio::streambuf` class. This support includes: + + * New `dynamic_string_buffer` and `dynamic_vector_buffer` adapter classes + that meet the `DynamicBufferSequence` type requirements. + + * New `dynamic_buffer()` factory functions for creating a dynamic buffer + adapter for a `vector` or `string`. + + * New overloads for the `read()`, `async_read()`, `write()` and + `async_write()`, `read_until()` and `async_read_until()` free functions + that directly support dynamic buffer sequences. + + * Support for networks and address ranges. Thanks go to Oliver Kowalke for + contributing to the design and providing the implementation on which this + facility is based.

This support requires that the + language extensions be enabled. Due to the restricted facilities exposed by + the Windows Runtime API, the port also comes with the following caveats: + + * The core facilities such as the `io_service`, `strand`, buffers, composed + operations, timers, etc., should all work as normal. + + * For sockets, only client-side TCP is supported. + + * Explicit binding of a client-side TCP socket is not supported. + + * The `cancel()` function is not supported for sockets. Asynchronous + operations may only be cancelled by closing the socket. + + * Operations that use `null_buffers` are not supported. + + * Only `tcp::no_delay` and `socket_base::keep_alive` options are supported. + + * Resolvers do not support service names, only numbers. I.e. you must + use "80" rather than "http". + + * Most resolver query flags have no effect. + +* Extended the ability to use Asio without Boost to include Microsoft Visual + Studio 2012. When using a C++11 compiler, most of Asio may now be used + without a dependency on Boost header files or libraries. To use Asio in this + way, define `ASIO_STANDALONE` on your compiler command line or as part of the + project options. This standalone configuration has been tested for the + following platforms and compilers: + + * Microsoft Visual Studio 2012 + + * Linux with g++ 4.7 or 4.8 (requires [^-std=c++11]) + + * Mac OS X with clang++ / Xcode 4.6 (requires [^-std=c++11 -stdlib=libc++]) + +* Fixed a regression (introduced in 1.10.0) where, on some platforms, errors + from `async_connect` were not correctly propagated through to the completion + handler. + +* Fixed a Windows-specific regression (introduced in 1.10.0) that occurs when + multiple threads are running an `io_service`. When the bug occurs, the result + of an asynchronous operation (error and bytes tranferred) is incorrectly + discarded and zero values used instead. For TCP sockets this results in + spurious end-of-file notifications. + +* Fixed a bug in handler tracking, where it was not correctly printing out some + handler IDs. + +* Fixed the comparison used to test for successful synchronous accept + operations so that it works correctly with unsigned socket descriptors. + +* Ensured the signal number is correctly passed to the completion handler when + starting an `async_wait` on a signal that is already raised. + +* Suppressed a g++ 4.8+ warning about unused typedefs. + +* Enabled the move optimisation for handlers that use the default invocation + hook. + +* Clarified that programs must not issue overlapping `async_write_at` + operations. + +* Changed the Windows `HANDLE` backend to treat `ERROR_MORE_DATA` as a + non-fatal error when returned by `GetOverlappedResult` for a synchronous + read. + +* Visual C++ language extensions use `generic` as a keyword. Added a + workaround that renames the namespace to `cpp_generic` when those language + extensions are in effect. + +* Fixed some asynchronous operations that missed out on getting `async_result` + support in 1.10.0. In particular, the buffered stream templates have been + updated so that they adhere to current handler patterns. + +* Enabled move support for Microsoft Visual Studio 2012. + +* Added `use_future` support for Microsoft Visual Studio 2012. + +* Removed a use of `std::min` in the Windows IOCP backend to avoid a + dependency on the `` header. + +* Eliminated some unnecessary handler copies. + +* Fixed support for older versions of OpenSSL that do not provide the + `SSL_CTX_clear_options` function. + +* Fixed various minor and cosmetic issues in code and documentation. + +[heading Asio 1.10.0] + +* Added new traits classes, `handler_type` and `async_result`, that allow the + customisation of the return type of an initiating function. + +* Added the `asio::spawn()` function, a high-level wrapper for running + stackful coroutines, based on the Boost.Coroutine library. The `spawn()` + function enables programs to implement asynchronous logic in a synchronous + manner. For example: `size_t n = my_socket.async_read_some(my_buffer, yield);`. + For further information, see [link asio.overview.core.spawn Stackful + Coroutines]. + +* Added the `asio::use_future` special value, which provides first-class + support for returning a C++11 `std::future` from an asynchronous + operation's initiating function. For example: + `future = my_socket.async_read_some(my_buffer, asio::use_future);`. + For further information, see [link asio.overview.cpp2011.futures C++ + 2011 Support - Futures]. + +* Promoted the stackless coroutine class and macros to be part of Asio's + documented interface, rather than part of the HTTP server 4 example. + For further information, see [link asio.overview.core.coroutine + Stackless Coroutines]. + +* Added a new handler hook called `asio_handler_is_continuation`. + Asynchronous operations may represent a continuation of the asynchronous + control flow associated with the current executing handler. The + `asio_handler_is_continuation` hook can be customised to return `true` if + this is the case, and Asio's implementation can use this knowledge to + optimise scheduling of the new handler. To cover common cases, Asio + customises the hook for strands, `spawn()` and composed asynchronous + operations. + +* Added four new generic protocol classes, `generic::datagram_protocol`, + `generic::raw_protocol`, `generic::seq_packet_protocol` and + `generic::stream_protocol`, which implement the `Protocol` type + requirements, but allow the user to specify the address family (e.g. + `AF_INET`) and protocol type (e.g. `IPPROTO_TCP`) at runtime. + For further information, see [link + asio.overview.networking.other_protocols Support for Other Protocols]. + +* Added C++11 move constructors that allow the conversion of a socket (or + acceptor) into a more generic type. For example, an `ip::tcp::socket` can + be converted into a `generic::stream_protocol::socket` via move + construction. + For further information, see [link + asio.overview.networking.other_protocols Support for Other Protocols]. + +* Extended the `basic_socket_acceptor<>`'s `accept()` and `async_accept()` + functions to allow a new connection to be accepted directly into a socket + of a more generic type. For example, an `ip::tcp::acceptor` can be used to + accept into a `generic::stream_protocol::socket` object. + For further information, see [link + asio.overview.networking.other_protocols Support for Other Protocols]. + +* Moved existing examples into a C++03-specific directory, and added a new + directory for C++11-specific examples. A limited subset of the C++03 + examples have been converted to their C++11 equivalents. + +* Add the ability to use Asio without Boost, for a limited set of platforms. + When using a C++11 compiler, most of Asio may now be used without a + dependency on Boost header files or libraries. To use Asio in this way, + define `ASIO_STANDALONE` on your compiler command line or as part of the + project options.

Thanks go to Nick Jones, on whose work these changes + are based. + + * Added support for SSL handshakes with re-use of data already read from + the wire. New overloads of the `ssl::stream<>` class's `handshake()` and + `async_handshake()` functions have been added. These accept a + `ConstBufferSequence` to be used as initial input to the ssl engine for + the handshake procedure. + + * Added support for creation of TLSv1.1 and TLSv1.2 `ssl::context` objects. + + * Added a `set_verify_depth()` function to the `ssl::context` and + `ssl::stream<>` classes. + + * Added the ability to load SSL certificate and key data from memory + buffers. New functions, `add_certificate_authority()`, + `use_certificate()`, `use_certificate_chain()`, `use_private_key()`, + `use_rsa_private_key()` and `use_tmp_dh()`, have been added to the + `ssl::context` class. + + * Changed `ssl::context` to automatically disable SSL compression by + default. To enable, use the new `ssl::context::clear_options()` function, + as in `my_context.clear_options(ssl::context::no_compression)`. + +* Fixed a potential deadlock in `signal_set` implementation. + +* Fixed an error in acceptor example in documentation. + +* Fixed copy-paste errors in waitable timer documentation. + +* Added assertions to satisfy some code analysis tools. + +* Fixed a malformed `#warning` directive. + +* Fixed a potential data race in the Linux `epoll` implementation. + +* Fixed a Windows-specific bug, where certain operations might generate an + `error_code` with an invalid (i.e. `NULL`) `error_category`. + +* Fixed `basic_waitable_timer`'s underlying implementation so that it can + handle any `time_point` value without overflowing the intermediate duration + objects. + +* Fixed a problem with lost thread wakeups that can occur when making + concurrent calls to `run()` and `poll()` on the same `io_service` object. + +* Fixed implementation of asynchronous connect operation so that it can cope + with spurious readiness notifications from the reactor. + +* Fixed a memory leak in the `ssl::rfc2818_verification` class. + +* Added a mechanism for disabling automatic Winsock initialisation. See the + header file [^asio/detail/winsock_init.hpp] for details. + +[heading Asio 1.8.3] + +* Fixed some 64-to-32-bit conversion warnings. + +* Fixed various small errors in documentation and comments. + +* Fixed an error in the example embedded in `basic_socket::get_option`'s + documentation. + +* Changed to use `long` rather than `int` for SSL_CTX options, to match OpenSSL. + +* Changed to use `_snwprintf` to address a compile error due to the changed + `swprintf` signature in recent versions of MinGW. + +* Fixed a deadlock that can occur on Windows when shutting down a pool of + `io_service` threads due to running out of work. + +* Changed UNIX domain socket example to treat errors from `accept` as non-fatal. + +* Added a small block recycling optimisation to improve default memory + allocation behaviour. + +[heading Asio 1.8.2] + +* Fixed an incompatibility between `ip::tcp::iostream` and C++11. + +* Decorated GCC attribute names with underscores to prevent interaction + with user-defined macros. + +* Added missing `#include `, needed for some versions of MinGW. + +* Changed to use [^gcc]'s atomic builtins on ARM CPUs, when available. + +* Changed strand destruction to be a no-op, to allow strand objects to be + destroyed after their associated `io_service` has been destroyed. + +* Added support for some newer versions of glibc which provide the + `epoll_create1()` function but always fail with ENOSYS. + +* Changed the SSL implementation to throw an exception if SSL engine + initialisation fails. + +* Fixed another regression in `buffered_write_stream`. + +* Implemented various minor performance improvements, primarily targeted at + Linux x86 and x86-64 platforms. + +[heading Asio 1.8.1] + +* Changed the `epoll_reactor` backend to do lazy registration for `EPOLLOUT` + events. + +* Fixed the `epoll_reactor` handling of out-of-band data, which was broken by + an incomplete fix in the last release. + +* Changed Asio's SSL wrapper to respect OpenSSL's `OPENSSL_NO_ENGINE` feature + test `#define`. + +* Fixed `windows::object_handle` so that it works with Windows compilers that + support C++11 move semantics (such as [^g++]). + +* Improved the performance of strand rescheduling. + +* Added support for [^g++] 4.7 when compiling in C++11 mode. + +* Fixed a problem where `signal_set` handlers were not being delivered when + the `io_service` was constructed with a `concurrency_hint` of 1. + +[heading Asio 1.8.0] + +* Added a new class template `basic_waitable_timer` based around the C++11 clock + type requirements. It may be used with the clocks from the C++11 `` + library facility or, if those are not available, Boost.Chrono. The typedefs + `high_resolution_timer`, `steady_timer` and `system_timer` may be used to + create timer objects for the standard clock types. + +* Added a new `windows::object_handle` class for performing waits on Windows + kernel objects. Thanks go to Boris Schaeling for contributing substantially + to the development of this feature. + +* On Linux, `connect()` can return EAGAIN in certain circumstances. Remapped + this to another error so that it doesn't look like a non-blocking operation. + +* Fixed a compile error on NetBSD. + +* Fixed deadlock on Mac OS X. + +* Fixed a regression in `buffered_write_stream`. + +* Fixed a non-paged pool "leak" on Windows when an `io_service` is repeatedly + run without anything to do. + +* Reverted earlier change to allow some speculative operations to be performed + without holding the lock, as it introduced a race condition in some + multithreaded scenarios. + +* Fixed a bug where the second buffer in an array of two buffers may be ignored + if the first buffer is empty. + +[heading Asio 1.6.1] + +* Implemented various performance improvements, including: + + * Using thread-local operation queues in single-threaded use cases (i.e. when + `concurrency_hint` is 1) to eliminate a lock/unlock pair. + + * Allowing some `epoll_reactor` speculative operations to be performed + without holding the lock. + + * Improving locality of reference by performing an `epoll_reactor`'s I/O + operation immediately before the corresponding handler is called. This also + improves scalability across CPUs when multiple threads are running the + `io_service`. + + * Specialising asynchronous read and write operations for buffer sequences + that are arrays (`boost::array` or `std::array`) of exactly two buffers. + +* Fixed a compile error in the regex overload of `async_read_until`. + +* Fixed a Windows-specific compile error by explicitly specifying the + `signal()` function from the global namespace. + +* Changed the `deadline_timer` implementation so that it does not read the + clock unless the timer heap is non-empty. + +* Changed the SSL stream's buffers' sizes so that they are large enough to hold + a complete TLS record. + +* Fixed the behaviour of the synchronous `null_buffers` operations so that they + obey the user's non-blocking setting. + +* Changed to set the size of the select `fd_set` at runtime when using Windows. + +* Disabled an MSVC warning due to const qualifier being applied to function type. + +* Fixed a crash that occurs when using the Intel C++ compiler. + +* Changed the initialisation of the OpenSSL library so that it supports all + available algorithms. + +* Fixed the SSL error mapping used when the session is gracefully shut down. + +* Added some latency test programs. + +* Clarified that a read operation ends when the buffer is full. + +* Fixed an exception safety issue in `epoll_reactor` initialisation. + +* Made the number of strand implementations configurable by defining + `(BOOST_)ASIO_STRAND_IMPLEMENTATIONS` to the desired number. + +* Added support for a new `(BOOST_)ASIO_ENABLE_SEQUENTIAL_STRAND_ALLOCATION` flag + which switches the allocation of strand implementations to use a round-robin + approach rather than hashing. + +* Fixed potential strand starvation issue that can occur when `strand.post()` + is used. + +[heading Asio 1.6.0] + +* Improved support for C++0x move construction to further reduce copying of + handler objects. In certain designs it is possible to eliminate virtually all + copies. Move support is now enabled when compiling in [^-std=c++0x] mode on + g++ 4.5 or higher. + +* Added build support for platforms that don't provide either of `signal()` or + `sigaction()`. + +* Changed to use C++0x variadic templates when they are available, rather than + generating function overloads using the Boost.Preprocessor library. + +* Ensured the value of `errno` is preserved across the implementation's signal + handler. + +* On Windows, ensured the count of outstanding work is decremented for + abandoned operations (i.e. operations that are being cleaned up within the + `io_service` destructor). + +* Fixed behaviour of zero-length reads and writes in the new SSL implementation. + +* Added support for building with OpenSSL 1.0 when `OPENSSL_NO_SSL2` is defined. + +* Changed most examples to treat a failure by an accept operation as non-fatal. + +* Fixed an error in the [^tick_count_timer] example by making the duration type + signed. Previously, a wait on an already-passed deadline would not return for + a very long time. + +[heading Asio 1.5.3] + +* Added a new, completely rewritten SSL implementation. The new implementation + compiles faster, shows substantially improved performance, and supports + custom memory allocation and handler invocation. It includes new API features + such as certificate verification callbacks and has improved error reporting. + The new implementation is source-compatible with the old for most uses. + However, if necessary, the old implementation may still be used by defining + `(BOOST_)ASIO_ENABLE_OLD_SSL`. + +* Added new `asio::buffer()` overloads for `std::array`, when available. The + support is automatically enabled when compiling in [^-std=c++0x] mode on g++ + 4.3 or higher, or when using MSVC 10. The support may be explicitly enabled + by defining `(BOOST_)ASIO_HAS_STD_ARRAY`, or disabled by defining + `(BOOST_)ASIO_DISABLE_STD_ARRAY`. + +* Changed to use the C++0x standard library templates `array`, `shared_ptr`, + `weak_ptr` and `atomic` when they are available, rather than the Boost + equivalents. + +* Support for `std::error_code` and `std::system_error` is no longer enabled by + default for g++ 4.5, as that compiler's standard library does not implement + `std::system_error::what()` correctly. + +[heading Asio 1.5.2] + +* Added support for C++0x move construction and assignment to sockets, serial + ports, POSIX descriptors and Windows handles. + +* Added support for the `fork()` system call. Programs that use `fork()` must + call `io_service.notify_fork()` at the appropriate times. Two new examples + have been added showing how to use this feature. + +* Cleaned up the handling of errors reported by the `close()` system call. In + particular, assume that most operating systems won't have `close()` fail with + `EWOULDBLOCK`, but if it does then set the blocking mode and restart the call. + If any other error occurs, assume the descriptor is closed. + +* The kqueue flag `EV_ONESHOT` seems to cause problems on some versions of Mac + OS X, with the `io_service` destructor getting stuck inside the `close()` + system call. Changed the kqueue backend to use `EV_CLEAR` instead. + +* Changed exception reporting to include the function name in exception `what()` + messages. + +* Fixed an insufficient initialisers warning with MinGW. + +* Changed the `shutdown_service()` member functions to be private. + +* Added archetypes for testing socket option functions. + +* Added a missing lock in `signal_set_service::cancel()`. + +* Fixed a copy/paste error in `SignalHandler` example. + +* Added the inclusion of the signal header to `signal_set_service.hpp` so that + constants like `NSIG` may be used. + +* Changed the `signal_set_service` implementation so that it doesn't assume + that `SIGRTMAX` is a compile-time constant. + +* Changed the Boost.Asio examples so that they don't use Boost.Thread's + convenience header. Use the header file that is specifically for the + boost::thread class instead. + +[heading Asio 1.5.1] + +* Added support for signal handling, using a new class called `signal_set`. + Programs may add one or more signals to the set, and then perform an + `async_wait()` operation. The specified handler will be called when one of + the signals occurs. The same signal number may registered with multiple + `signal_set` objects, however the signal number must be used only with Asio. + +* Added handler tracking, a new debugging aid. When enabled by defining + `(BOOST_)ASIO_ENABLE_HANDLER_TRACKING`, Asio writes debugging output to the + standard error stream. The output records asynchronous operations and the + relationships between their handlers. It may be post-processed using the + included [^handlerviz.pl] tool to create a visual representation of the + handlers (requires GraphViz). + +* Fixed a bug in `asio::streambuf` where the `consume()` function did not + always update the internal buffer pointers correctly. The problem may occur + when the `asio::streambuf` is filled with data using the standard C++ member + functions such as `sputn()`. (Note: the problem does not manifest when the + streambuf is populated by the Asio free functions `read()`, + `async_read()`, `read_until()` or `async_read_until()`.) + +* Fixed a bug on kqueue-based platforms, where reactor read operations that + return false from their `perform()` function are not correctly re-registered + with kqueue. + +* Support for `std::error_code` and `std::system_error` is no longer enabled by + default for MSVC10, as that compiler's standard library does not implement + `std::system_error::what()` correctly. + +* Modified the `buffers_iterator<>` and `ip::basic_resolver_iterator` classes + so that the value_type typedefs are non-const byte types. + +[heading Asio 1.5.0] + +* Added support for timeouts on socket iostreams, such as `ip::tcp::iostream`. + A timeout is set by calling `expires_at()` or `expires_from_now()` to + establish a deadline. Any socket operations which occur past the deadline + will put the iostream into a bad state. + +* Added a new `error()` member function to socket iostreams, for retrieving the + error code from the most recent system call. + +* Added a new `basic_deadline_timer::cancel_one()` function. This function lets + you cancel a single waiting handler on a timer. Handlers are cancelled in + FIFO order. + +* Added a new `transfer_exactly()` completion condition. This can be used to + send or receive a specified number of bytes even if the total size of the + buffer (or buffer sequence) is larger. + +* Added new free functions `connect()` and `async_connect()`. These operations + try each endpoint in a list until the socket is successfully connected. + +* Extended the `buffer_size()` function so that it works for buffer sequences + in addition to individual buffers. + +* Added a new `buffer_copy()` function that can be used to copy the raw bytes + between individual buffers and buffer sequences. + +* Added new non-throwing overloads of `read()`, `read_at()`, `write()` and + `write_at()` that do not require a completion condition. + +* Added friendlier compiler errors for when a completion handler does not meet + the necessary type requirements. When C++0x is available (currently supported + for g++ 4.5 or later, and MSVC 10), `static_assert` is also used to generate + an informative error message. This checking may be disabled by defining + `(BOOST_)ASIO_DISABLE_HANDLER_TYPE_REQUIREMENTS`. + +* Added support for using `std::error_code` and `std::system_error`, when + available. The support is automatically enabled when compiling in + [^-std=c++0x] mode on g++ 4.5 or higher, or when using MSVC 10. The support + may be explicitly enabled by defining `ASIO_HAS_STD_SYSTEM_ERROR`, or + disabled by defining `ASIO_DISABLE_STD_SYSTEM_ERROR`. (Available in non-Boost + version of Asio only.) + +* Made the `is_loopback()`, `is_unspecified()` and `is_multicast()` functions + consistently available across the `ip::address`, `ip::address_v4` and + `ip::address_v6` classes. + +* Added new `non_blocking()` functions for managing the non-blocking behaviour + of a socket or descriptor. The `io_control()` commands named `non_blocking_io` + are now deprecated in favour of these new functions. + +* Added new `native_non_blocking()` functions for managing the non-blocking + mode of the underlying socket or descriptor. These functions are intended to + allow the encapsulation of arbitrary non-blocking system calls as + asynchronous operations, in a way that is transparent to the user of the + socket object. The functions have no effect on the behaviour of the + synchronous operations of the socket or descriptor. + +* Added the `io_control()` member function for socket acceptors. + +* For consistency with the C++0x standard library, deprecated the `native_type` + typedefs in favour of `native_handle_type`, and the `native()` member + functions in favour of `native_handle()`. + +* Added a `release()` member function to posix descriptors. This function + releases ownership of the underlying native descriptor to the caller. + +* Added support for sequenced packet sockets (`SOCK_SEQPACKET`). + +* Added a new `io_service::stopped()` function that can be used to determine + whether the `io_service` has stopped (i.e. a `reset()` call is needed prior + to any further calls to `run()`, `run_one()`, `poll()` or `poll_one()`). + +* Reduced the copying of handler function objects. + +* Added support for C++0x move construction to further reduce copying of + handler objects. Move support is enabled when compiling in [^-std=c++0x] mode + on g++ 4.5 or higher, or when using MSVC10. + +* Removed the dependency on OS-provided macros for the well-known IPv4 and IPv6 + addresses. This should eliminate the annoying "missing braces around + initializer" warnings. + +* Reduced the size of `ip::basic_endpoint<>` objects (such as + `ip::tcp::endpoint` and `ip::udp::endpoint`). + +* Changed the reactor backends to assume that any descriptors or sockets added + using `assign()` may have been `dup()`-ed, and so require explicit + deregistration from the reactor. + +* Changed the SSL error category to return error strings from the OpenSSL + library. + +* Changed the separate compilation support such that, to use Asio's SSL + capabilities, you should also include 'asio/ssl/impl/src.hpp` in one source + file in your program. + +* Removed the deprecated member functions named `io_service()`. The + `get_io_service()` member functions should be used instead. + +* Removed the deprecated typedefs `resolver_query` and `resolver_iterator` from + the `ip::tcp`, `ip::udp` and `ip::icmp` classes. + +* Fixed a compile error on some versions of g++ due to anonymous enums. + +* Added an explicit cast to the `FIONBIO` constant to int to suppress a compiler + warning on some platforms. + +* Fixed warnings reported by g++'s [^-Wshadow] compiler option. + +[heading Asio 1.4.8] + +* Fixed an integer overflow problem that occurs when + `ip::address_v4::broadcast()` is used on 64-bit platforms. + +* Fixed a problem on older Linux kernels (where epoll is used without `timerfd` + support) that prevents timely delivery of `deadline_timer` handlers, after the + program has been running for some time. + +[heading Asio 1.4.7] + +* Fixed a problem on kqueue-based platforms where a `deadline_timer` may + never fire if the `io_service` is running in a background thread. + +* Fixed a const-correctness issue that prevented valid uses of + `has_service<>` from compiling. + +* Fixed MinGW cross-compilation. + +* Removed dependency on deprecated Boost.System functions (Boost.Asio only). + +* Ensured `close()`/`closesocket()` failures are correctly propagated. + +* Added a check for errors returned by `InitializeCriticalSectionAndSpinCount`. + +* Added support for hardware flow control on QNX. + +* Always use `pselect()` on HP-UX, if it is available. + +* Ensured handler arguments are passed as lvalues. + +* Fixed Windows build when thread support is disabled. + +* Fixed a Windows-specific problem where `deadline_timer` objects with expiry + times set more than 5 minutes in the future may never expire. + +* Fixed the resolver backend on BSD platforms so that an empty service name + resolves to port number `0`, as per the documentation. + +* Fixed read operations so that they do not accept buffer sequences of type + `const_buffers_1`. + +* Redefined `Protocol` and `id` to avoid clashing with Objective-C++ keywords. + +* Fixed a `vector` reallocation performance issue that can occur when there are + many active `deadline_timer` objects. + +* Fixed the kqueue backend so that it compiles on NetBSD. + +* Fixed the socket `io_control()` implementation on 64-bit Mac OS X and BSD + platforms. + +* Fixed a Windows-specific problem where failures from `accept()` are + incorrectly treated as successes. + +* Deprecated the separate compilation header `asio/impl/src.cpp` in + favour of `asio/impl/src.hpp`. + +[heading Asio 1.4.6] + +* Reduced compile times. (Note that some programs may need to add additional + `#include`s, e.g. if the program uses boost::array but does not explicitly + include ``.) + +* Reduced the size of generated code. + +* Refactored `deadline_timer` implementation to improve performance. + +* Improved multiprocessor scalability on Windows by using a dedicated hidden + thread to wait for timers. + +* Improved performance of `asio::streambuf` with `async_read()` and + `async_read_until()`. These read operations now use the existing capacity of + the `streambuf` when reading, rather than limiting the read to 512 bytes. + +* Added optional separate compilation. To enable, include + `asio/impl/src.cpp` in one source file in a program, then + build the program with `(BOOST_)ASIO_SEPARATE_COMPILATION` defined in the + project\/compiler settings. Alternatively, `(BOOST_)ASIO_DYN_LINK` may be + defined to build a separately-compiled Asio as part of a shared library. + +* Added new macro `(BOOST_)ASIO_DISABLE_FENCED_BLOCK` to permit the disabling of + memory fences around completion handlers, even if thread support is enabled. + +* Reworked timeout examples to better illustrate typical use cases. + +* Ensured that handler arguments are passed as const types. + +* Fixed incorrect parameter order in `null_buffers` variant of `async_send_to`. + +* Ensured unsigned char is used with `isdigit` in `getaddrinfo` emulation. + +* Fixed handling of very small but non-zero timeouts. + +* Fixed crash that occurred when an empty buffer sequence was passed to a + composed read or write operation. + +* Added missing operator+ overload in `buffers_iterator`. + +* Implemented cancellation of `null_buffers` operations on Windows. + +[heading Asio 1.4.5] + +* Improved performance. + +* Reduced compile times. + +* Reduced the size of generated code. + +* Extended the guarantee that background threads don't call user code to + all asynchronous operations. + +* Changed to use edge-triggered epoll on Linux. + +* Changed to use `timerfd` for dispatching timers on Linux, when + available. + +* Changed to use one-shot notifications with kqueue on Mac OS X and BSD + platforms. + +* Added a bitmask type `ip::resolver_query_base::flags` as per the TR2 + proposal. This type prevents implicit conversion from `int` to + `flags`, allowing the compiler to catch cases where users incorrectly + pass a numeric port number as the service name. + +* Added `#define NOMINMAX` for all Windows compilers. Users can define + `(BOOST_)ASIO_NO_NOMINMAX` to suppress this definition. + +* Fixed a bug where 0-byte asynchronous reads were incorrectly passing + an `error::eof` result to the completion handler. + +* Changed the `io_control()` member functions to always call `ioctl` on + the underlying descriptor when modifying blocking mode. + +* Changed the resolver implementation so that it no longer requires the + typedefs `InternetProtocol::resolver_query` and + `InternetProtocol::resolver_iterator`, as neither typedef is part of + the documented `InternetProtocol` requirements. The corresponding + typedefs in the `ip::tcp`, `ip::udp` and `ip::icmp` classes have been + deprecated. + +* Fixed out-of-band handling for reactors not based on `select()`. + +* Added new `(BOOST_)ASIO_DISABLE_THREADS` macro that allows Asio's + threading support to be independently disabled. + +* Minor documentation improvements. + +[heading Asio 1.4.4] + +* Added a new HTTP Server 4 example illustrating the use of stackless + coroutines with Asio. + +* Changed handler allocation and invocation to use `boost::addressof` to + get the address of handler objects, rather than applying `operator&` + directly. + +* Restricted MSVC buffer debugging workaround to 2008, as it causes a + crash with 2010 beta 2. + +* Fixed a problem with the lifetime of handler memory, where Windows + needs the `OVERLAPPED` structure to be valid until both the initiating + function call has returned and the completion packet has been + delivered. + +* Don't block signals while performing system calls, but instead restart + the calls if they are interrupted. + +* Documented the guarantee made by strand objects with respect to order + of handler invocation. + +* Changed strands to use a pool of implementations, to make copying of + strands cheaper. + +* Ensured that kqueue support is enabled for BSD platforms. + +* Added a `boost_` prefix to the `extern "C"` thread entry point + function. + +* In `getaddrinfo` emulation, only check the socket type (`SOCK_STREAM` + or `SOCK_DGRAM`) if a service name has been specified. This should + allow the emulation to work with raw sockets. + +* Added a workaround for some broken Windows firewalls that make a + socket appear bound to 0.0.0.0 when it is in fact bound to 127.0.0.1. + +* Applied a fix for reported excessive CPU usage under Solaris. + +* Added some support for platforms that use older compilers such as g++ + 2.95. + +[heading Asio 1.4.3] + +* Added a new ping example to illustrate the use of ICMP sockets. + +* Changed the `buffered*_stream<>` templates to treat 0-byte reads and + writes as no-ops, to comply with the documented type requirements for + `SyncReadStream`, `AsyncReadStream`, `SyncWriteStream` and + `AsyncWriteStream`. + +* Changed some instances of the `throw` keyword to + `boost::throw_exception()` to allow Asio to be used when exception + support is disabled. Note that the SSL wrappers still require + exception support. + +* Made Asio compatible with the OpenSSL 1.0 beta. + +* Eliminated a redundant system call in the Solaris /dev/poll backend. + +* Fixed a bug in resizing of the bucket array in the internal hash maps. + +* Ensured correct propagation of the error code when a synchronous + accept fails. + +* Ensured correct propagation of the error code when a synchronous read + or write on a Windows `HANDLE` fails. + +* Fixed failures reported when `_GLIBCXX_DEBUG` is defined. + +* Fixed custom memory allocation support for timers. + +* Tidied up various warnings reported by g++. + +* Various documentation improvements, including more obvious hyperlinks + to function overloads, header file information, examples for the + handler type requirements, and adding enum values to the index. + +[heading Asio 1.4.2] + +* Implement automatic resizing of the bucket array in the internal hash + maps. This is to improve performance for very large numbers of + asynchronous operations and also to reduce memory usage for very small + numbers. A new macro `(BOOST_)ASIO_HASH_MAP_BUCKETS` may be used to + tweak the sizes used for the bucket arrays. (N.B. this feature + introduced a bug which was fixed in Asio 1.4.3 / Boost 1.40.) + +* Add performance optimisation for the Windows IOCP backend for when no + timers are used. + +* Prevent locale settings from affecting formatting of TCP and UDP + endpoints. + +* Fix a memory leak that occurred when an asynchronous SSL operation's + completion handler threw an exception. + +* Fix the implementation of `io_control()` so that it adheres to the + documented type requirements for IoControlCommand. + +* Fix incompatibility between Asio and ncurses.h. + +* On Windows, specifically handle the case when an overlapped `ReadFile` + call fails with `ERROR_MORE_DATA`. This enables a hack where a + `windows::stream_handle` can be used with a message-oriented named + pipe. + +* Fix system call wrappers to always clear the error on success, as + POSIX allows successful system calls to modify errno. + +* Don't include termios.h if `(BOOST_)ASIO_DISABLE_SERIAL_PORT` is + defined. + +* Cleaned up some more MSVC level 4 warnings. + +* Various documentation fixes. + +[heading Asio 1.4.1] + +* Improved compatibility with some Windows firewall software. + +* Ensured arguments to `windows::overlapped_ptr::complete()` are correctly + passed to the completion handler. + +* Fixed a link problem and multicast failure on QNX. + +* Fixed a compile error in SSL support on MinGW / g++ 3.4.5. + +* Drop back to using a pipe for notification if eventfd is not available + at runtime on Linux. + +* Various minor bug and documentation fixes. + +[heading Asio 1.4.0] + +* Enhanced CompletionCondition concept with the signature + `size_t CompletionCondition(error_code ec, size_t total)`, where the return + value indicates the maximum number of bytes to be transferred on the next + read or write operation. (The old CompletionCondition signature is still + supported for backwards compatibility). + +* New `windows::overlapped_ptr` class to allow arbitrary overlapped I/O + functions (such as `TransmitFile`) to be used with Asio. + +* On recent versions of Linux, an `eventfd` descriptor is now used (rather than + a pipe) to interrupt a blocked select/epoll reactor. + +* Added const overloads of `lowest_layer()`. + +* Synchronous read, write, accept and connect operations are now thread safe + (meaning that it is now permitted to perform concurrent synchronous + operations on an individual socket, if supported by the OS). + +* Reactor-based `io_service` implementations now use lazy initialisation to + reduce the memory usage of an `io_service` object used only as a message + queue. + +[heading Asio 1.2.0] + +* Added support for serial ports. + +* Added support for UNIX domain sockets. + +* Added support for raw sockets and ICMP. + +* Added wrappers for POSIX stream-oriented file descriptors (excluding regular + files). + +* Added wrappers for Windows stream-oriented `HANDLE`s such as named pipes + (requires `HANDLE`s that work with I/O completion ports). + +* Added wrappers for Windows random-access `HANDLE`s such as files (requires + `HANDLE`s that work with I/O completion ports). + +* Added support for reactor-style operations (i.e. they report readiness but + perform no I/O) using a new `null_buffers` type. + +* Added an iterator type for bytewise traversal of buffer sequences. + +* Added new `read_until()` and `async_read_until()` overloads that take a + user-defined function object for locating message boundaries. + +* Added an experimental two-lock queue (enabled by defining + `(BOOST_)ASIO_ENABLE_TWO_LOCK_QUEUE`) that may provide better `io_service` + scalability across many processors. + +* Various fixes, performance improvements, and more complete coverage of the + custom memory allocation support. + +[heading Asio 1.0.0] + +First stable release of Asio. + +[endsect] diff --git a/3rdparty/asio/src/doc/index.xml b/3rdparty/asio/src/doc/index.xml new file mode 100644 index 00000000000..3b7b556591c --- /dev/null +++ b/3rdparty/asio/src/doc/index.xml @@ -0,0 +1,13 @@ + + + + + +

Before using Asio it may be useful to get a conceptual +picture of the various parts of Asio, your program, and how they work together. + +As an introductory example, let's consider what happens when you perform a +connect operation on a socket. We shall start by examining synchronous +operations. + +[$sync_op.png] + +[*Your program] will have at least one [*io_context] object. The [*io_context] +represents [*your program]'s link to the [*operating system]'s I/O services. + + asio::io_context io_context; + +To perform I/O operations [*your program] will need an [*I/O object] such as a +TCP socket: + + asio::ip::tcp::socket socket(io_context); + +When a synchronous connect operation is performed, the following sequence of +events occurs: + +1. [*Your program] initiates the connect operation by calling the [*I/O +object]: + + socket.connect(server_endpoint); + +2. The [*I/O object] forwards the request to the [*io_context]. + +3. The [*io_context] calls on the [*operating system] to perform the connect +operation. + +4. The [*operating system] returns the result of the operation to the +[*io_context]. + +5. The [*io_context] translates any error resulting from the operation into an +object of type `asio::error_code`. An `error_code` may be compared with +specific values, or tested as a boolean (where a `false` result means that no +error occurred). The result is then forwarded back up to the [*I/O object]. + +6. The [*I/O object] throws an exception of type `asio::system_error` if the +operation failed. If the code to initiate the operation had instead been +written as: + + asio::error_code ec; + socket.connect(server_endpoint, ec); + +then the `error_code` variable `ec` would be set to the result of the +operation, and no exception would be thrown. + +When an asynchronous operation is used, a different sequence of events occurs. + +[$async_op1.png] + +1. [*Your program] initiates the connect operation by calling the [*I/O +object]: + + socket.async_connect(server_endpoint, your_completion_handler); + +where `your_completion_handler` is a function or function object with the +signature: + + void your_completion_handler(const asio::error_code& ec); + +The exact signature required depends on the asynchronous operation being +performed. The reference documentation indicates the appropriate form for each +operation. + +2. The [*I/O object] forwards the request to the [*io_context]. + +3. The [*io_context] signals to the [*operating system] that it should start an +asynchronous connect. + +Time passes. (In the synchronous case this wait would have been contained +entirely within the duration of the connect operation.) + +[$async_op2.png] + +4. The [*operating system] indicates that the connect operation has completed +by placing the result on a queue, ready to be picked up by the [*io_context]. + +5. [*Your program] must make a call to `io_context::run()` (or to one of the +similar [*io_context] member functions) in order for the result to be +retrieved. A call to `io_context::run()` blocks while there are unfinished +asynchronous operations, so you would typically call it as soon as you have +started your first asynchronous operation. + +6. While inside the call to `io_context::run()`, the [*io_context] dequeues the +result of the operation, translates it into an `error_code`, and then passes it +to [*your completion handler]. + +This is a simplified picture of how Asio operates. You will want to delve +further into the documentation if your needs are more advanced, such as +extending Asio to perform other types of asynchronous operations. + +[endsect] diff --git a/3rdparty/asio/src/doc/overview/bsd_sockets.qbk b/3rdparty/asio/src/doc/overview/bsd_sockets.qbk new file mode 100644 index 00000000000..acc67da29d4 --- /dev/null +++ b/3rdparty/asio/src/doc/overview/bsd_sockets.qbk @@ -0,0 +1,270 @@ +[/ + / Copyright (c) 2003-2016 Christopher M.

These buffers can be simply expressed as a tuple +consisting of a pointer and a size in bytes. However, to allow the development +of efficient network applications, Asio includes support for scatter-gather +operations. These operations involve one or more buffers: + +* A scatter-read receives data into multiple buffers. +* A gather-write transmits multiple buffers. + +Therefore we require an abstraction to represent a collection of buffers. The +approach used in Asio is to define a type (actually two types) to +represent a single buffer. These can be stored in a container, which may be +passed to the scatter-gather operations. + +In addition to specifying buffers as a pointer and size in bytes, Asio makes a +distinction between modifiable memory (called mutable) and non-modifiable +memory (where the latter is created from the storage for a const-qualified +variable). These two types could therefore be defined as follows: + + typedef std::pair mutable_buffer; + typedef std::pair const_buffer; + +Here, a mutable_buffer would be convertible to a const_buffer, but conversion +in the opposite direction is not valid. + +However, Asio does not use the above definitions as-is, but instead defines two +classes: `mutable_buffer` and `const_buffer`. The goal of these is to provide +an opaque representation of contiguous memory, where: + +* Types behave as std::pair would in conversions. That is, a `mutable_buffer` is + convertible to a `const_buffer`, but the opposite conversion is disallowed. + +* There is protection against buffer overruns. Given a buffer instance, a user + can only create another buffer representing the same range of memory or a + sub-range of it. To provide further safety, the library also includes + mechanisms for automatically determining the size of a buffer from an array, + `boost::array` or `std::vector` of POD elements, or from a `std::string`. + +* The underlying memory is explicitly accessed using the `data()` member + function. In general an application should never need to do this, but it is + required by the library implementation to pass the raw memory to the + underlying operating system functions. + +Finally, multiple buffers can be passed to scatter-gather operations (such as +[link asio.reference.read read()] or [link asio.reference.write write()]) by +putting the buffer objects into a container. The `MutableBufferSequence` and +`ConstBufferSequence` concepts have been defined so that containers such as +`std::vector`, `std::list`, `std::vector` or `boost::array` can be used. + +[heading Streambuf for Integration with Iostreams] + +The class `asio::basic_streambuf` is derived from `std::basic_streambuf` to +associate the input sequence and output sequence with one or more objects of +some character array type, whose elements store arbitrary values. These +character array objects are internal to the streambuf object, but direct access +to the array elements is provided to permit them to be used with I/O +operations, such as the send or receive operations of a socket: + +* The input sequence of the streambuf is accessible via the [link + asio.reference.basic_streambuf.data data()] member function. The return type + of this function meets the `ConstBufferSequence` requirements. + +* The output sequence of the streambuf is accessible via the [link + asio.reference.basic_streambuf.data prepare()] member function. The return + type of this function meets the `MutableBufferSequence` requirements. + +* Data is transferred from the front of the output sequence to the back of the + input sequence by calling the [link asio.reference.basic_streambuf.commit + commit()] member function. + +* Data is removed from the front of the input sequence by calling the [link + asio.reference.basic_streambuf.consume consume()] member function. + +The streambuf constructor accepts a `size_t` argument specifying the maximum of +the sum of the sizes of the input sequence and output sequence. Any operation +that would, if successful, grow the internal data beyond this limit will throw +a `std::length_error` exception. + +[heading Bytewise Traversal of Buffer Sequences] + +The `buffers_iterator<>` class template allows buffer sequences (i.e. types +meeting `MutableBufferSequence` or `ConstBufferSequence` requirements) to be +traversed as though they were a contiguous sequence of bytes. Helper functions +called buffers_begin() and buffers_end() are also provided, where the +buffers_iterator<> template parameter is automatically deduced. + +As an example, to read a single line from a socket and into a `std::string`, +you may write: + + asio::streambuf sb; + ... + std::size_t n = asio::read_until(sock, sb, '\n'); + asio::streambuf::const_buffers_type bufs = sb.data(); + std::string line( + asio::buffers_begin(bufs), + asio::buffers_begin(bufs) + n); + +[heading Buffer Debugging] + +Some standard library implementations, such as the one that ships with +Microsoft Visual C++ 8.0 and later, provide a feature called iterator +debugging. What this means is that the validity of iterators is checked at +runtime. If a program tries to use an iterator that has been invalidated, an +assertion will be triggered. For example: + + std::vector v(1) + std::vector::iterator i = v.begin(); + v.clear(); // invalidates iterators + *i = 0; // assertion! + +Asio takes advantage of this feature to add buffer debugging. Consider the +following code: + + void dont_do_this() + { + std::string msg = "Hello, world!"; + asio::async_write(sock, asio::buffer(msg), my_handler); + } + +When you call an asynchronous read or write you need to ensure that the buffers +for the operation are valid until the completion handler is called. In the +above example, the buffer is the `std::string` variable `msg`. This variable is +on the stack, and so it goes out of scope before the asynchronous operation +completes. If you're lucky then the application will crash, but random failures +are more likely. + +When buffer debugging is enabled, Asio stores an iterator into the string until +the asynchronous operation completes, and then dereferences it to check its +validity. In the above example you would observe an assertion failure just +before Asio tries to call the completion handler. + +This feature is automatically made available for Microsoft Visual Studio 8.0 or +later and for GCC when `_GLIBCXX_DEBUG` is defined. There is a performance cost +to this checking, so buffer debugging is only enabled in debug builds. For +other compilers it may be enabled by defining `ASIO_ENABLE_BUFFER_DEBUGGING`. +It can also be explicitly disabled by defining `ASIO_DISABLE_BUFFER_DEBUGGING`. + +[heading See Also] + +[link asio.reference.buffer buffer], +[link asio.reference.buffers_begin buffers_begin], +[link asio.reference.buffers_end buffers_end], +[link asio.reference.buffers_iterator buffers_iterator], +[link asio.reference.const_buffer const_buffer], +[link asio.reference.const_buffers_1 const_buffers_1], +[link asio.reference.mutable_buffer mutable_buffer], +[link asio.reference.mutable_buffers_1 mutable_buffers_1], +[link asio.reference.streambuf streambuf], +[link asio.reference.ConstBufferSequence ConstBufferSequence], +[link asio.reference.MutableBufferSequence MutableBufferSequence], +[link asio.examples.cpp03_examples.buffers buffers example (C++03)], +[link asio.examples.cpp11_examples.buffers buffers example (c++11)]. + +[endsect] diff --git a/3rdparty/asio/src/doc/overview/coroutine.qbk b/3rdparty/asio/src/doc/overview/coroutine.qbk new file mode 100644 index 00000000000..67453674eae --- /dev/null +++ b/3rdparty/asio/src/doc/overview/coroutine.qbk @@ -0,0 +1,51 @@ +[/ + / Copyright (c) 2003-2016 Christopher M.

The library +implementation for each operating system should use the mechanism that best +enables this scalability. + +* [*Efficiency.] The library should support techniques such as scatter-gather +I/O, and allow programs to minimise data copying. + +* [*Model concepts from established APIs, such as BSD sockets.] The +BSD socket API is widely implemented and understood, and is covered in much +literature. Other programming languages often use a similar interface for +networking APIs. As far as is reasonable, Asio should leverage existing +practice. + +* [*Ease of use.] The library should provide a lower entry barrier for new +users by taking a toolkit, rather than framework, approach. That is, it should +try to minimise the up-front investment in time to just learning a few basic +rules and guidelines. After that, a library user should only need to understand +the specific functions that are being used. + +* [*Basis for further abstraction.] The library should permit the development +of other libraries that provide higher levels of abstraction.

Use of strands allows execution of code in a +multithreaded program without the need for explicit locking (e.g. using +mutexes). + +Strands may be either implicit or explicit, as illustrated by the following +alternative approaches: + +* Calling io_context::run() from only one thread means all event handlers + execute in an implicit strand, due to the io_context's guarantee that handlers + are only invoked from inside run(). + +* Where there is a single chain of asynchronous operations associated with a + connection (e.g. in a half duplex protocol implementation like HTTP) there is + no possibility of concurrent execution of the handlers. This is an implicit + strand. + +* An explicit strand is an instance of `strand<>` or `io_context::strand`. All + event handler function objects need to be bound to the strand using + `asio::bind_executor()` or otherwise posted/dispatched through the strand + object. + +In the case of composed asynchronous operations, such as `async_read()` or +`async_read_until()`, if a completion handler goes through a strand, then all +intermediate handlers should also go through the same strand. This is needed to +ensure thread safe access for any objects that are shared between the caller +and the composed operation (in the case of `async_read()` it's the socket, +which the caller can `close()` to cancel the operation). + +This is done by partially specialising the `asio::ssociated_executor<>` trait +for all intermediate handlers. This trait forwards to the corresponding trait +specialisation for the final handler: + + struct my_handler + { + void operator()() { ... } + }; + + namespace asio { + + template + struct associated_executor + { + // Custom implementation of Executor type requirements. + typedef my_executor type; + + // Return a custom executor implementation. + static type get(const my_handler&, const Executor& = Executor()) + { + return my_executor(); + } + }; + + } // namespace asio + +The `asio::bind_executor()` function is a helper to bind a specific executor +object, such as a strand, to a completion handler. This binding automatically +specialises the `associated_executor` trait as shown above. For example, to +bind a strand to a completion handler we would simply write: + + my_socket.async_read_some(my_buffer, + asio::bind_executor(my_strand, + [](error_code ec, size_t length) + { + // ... + })); + +[heading See Also] + +[link asio.reference.bind_executor bind_executor], +[link asio.reference.strand strand], +[link asio.reference.io_context__strand io_context::strand], +[link asio.tutorial.tuttimer5 tutorial Timer.5], +[link asio.examples.cpp03_examples.http_server_3 HTTP server 3 example]. + +[endsect] diff --git a/3rdparty/asio/src/doc/overview/streams.qbk b/3rdparty/asio/src/doc/overview/streams.qbk new file mode 100644 index 00000000000..ea89e8b5d62 --- /dev/null +++ b/3rdparty/asio/src/doc/overview/streams.qbk @@ -0,0 +1,62 @@ +[/ + / Copyright (c) 2003-2016 Christopher M.

This approach may also be used with +`io_context::post()` to use a means to perform any computational tasks across a +thread pool. + +Note that all threads that have joined an `io_context`'s pool are considered +equivalent, and the `io_context` may distribute work across them in an +arbitrary fashion. + +[heading Internal Threads] + +The implementation of this library for a particular platform may make use of +one or more internal threads to emulate asynchronicity. As far as possible, +these threads must be invisible to the library user. In particular, the threads: + +* must not call the user's code directly; and + +* must block all signals. + +This approach is complemented by the following guarantee: + +* Asynchronous completion handlers will only be called from threads that are + currently calling `io_context::run()`. + +Consequently, it is the library user's responsibility to create and manage all +threads to which the notifications will be delivered. + +The reasons for this approach include: + +* By only calling `io_context::run()` from a single thread, the user's code can + avoid the development complexity associated with synchronisation. For + example, a library user can implement scalable servers that are + single-threaded (from the user's point of view). + +* A library user may need to perform initialisation in a thread shortly after + the thread starts and before any other application code is executed.
