* 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. Checking may be disabled by defining BOOST_ASIO_DISABLE_HANDLER_TYPE_REQUIREMENTS. * Made the is_loopback(), is_unspecified() and is_multicast() functions consistently available across the ip::address, ip::address_v4 and ip::address_v6 classes. Refs #3939. * 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. Refs #3307. * Added the io_control() member function for socket acceptors. Refs #3297. * 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. Refs #3900. * 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. Refs #3741. * 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. Refs #4971. * 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. Refs #4883. * Added an explicit cast to the FIONBIO constant to int to suppress a compiler warning on some platforms. Refs #5128. * Fixed warnings reported by g++'s -Wshadow compiler option. Refs #3905. [SVN r69194]
