* Duration type should be signed in tick_count_timer example.
* Regenerate documentation.
* Make definition of BOOST_ASIO_MOVE_ARG and BOOST_ASIO_MOVE_CAST separate to
the definition of BOOST_ASIO_HAS_MOVE, to allow the latter to be user-defined.
[SVN r72404]
* On Windows, ensure the count of outstanding work is decremented for
abandoned operations (i.e. operations that are being cleaned up within
the io_service destructor).
* Fix basic_socket_streambuf compile error when using MSVC 10's std::array.
* Preserve the value of errno across the signal handler.
* Fix unused return value warning.
* Fix various minor documentation errors.
[SVN r70751]
* Improve backward compatibility of the new SSL implementation.
* Add wrapper for SSL_CTX_set_default_verify_paths().
* Document which OpenSSL functions the ssl::context member functions use.
* Add SSL certificate verification callbacks, and add a new
ssl::rfc2818_verification function object for simple peer certificate
verification based on the host name.
* Use std::atomic<> when available.
* Prefer to use std::array when it is available.
* Use std::shared_ptr and std::weak_ptr when available.
* Use a lightweight scoped smart pointer.
* Fix some shadow variable warnings with g++ 4.6.
[SVN r70384]
* Added support for C++0x move construction and assignment to sockets, serial
ports, POSIX descriptors and Windows handles.
* Regenerate documentation.
[SVN r70092]
* 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.
* Modified the buffers_iterator<> and ip::basic_resolver_iterator
classes so that the value_type typedefs are non-const byte types.
[SVN r69198]
* 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]
InternetProtocol::resolver_query and InternetProtocol::resolver_iterator,
as neither typedef is part of the documented InternetProtocol requirements.
The following typedefs are now marked as deprecated:
- ip::icmp::resolver_query
- ip::icmp::resolver_iterator
- ip::tcp::resolver_query
- ip::tcp::resolver_iterator
- ip::udp::resolver_query
- ip::udp::resolver_iterator
