* dynamic_buffer_ref is removed, because Asio / Networking
has introduced the DynamicBuffer_v2 concept which is incompatible
with Beast's storage types.
The next version of Beast (1.70) will provide changes to
interoperate with Asio / Networking's new concepts.
* All functionality of stranded_stream is folded into basic_stream
* tcp_stream is an alias for basic_stream with tcp
* The tests are expanded to produce full coverage
* Timeout implementation is simplified
* is_completion_handler is deprecated
* type_traits.hpp is a deprecated include
These items will be removed in the next version
* Include the new header file for the types needed:
- stream_traits.hpp
- file_base.hpp
* Use std::is_invocable instead of is_completion_handler
fix#1417
* New get_lowest_layer free function works for any object
* New lowest_layer_type trait works for any object
* New examples and documentation on layered streams
API Changes:
* The member function lowest_layer is removed from all
types provided by the library:
Actions Required:
* Call the free function get_lowest_layer instead of
member lowest_layer.
This I/O object wraps an ordinary socket and provides a built-in
timeout and optional bandwidth rate-limiting facility.
Added class template basic_stream_socket
* Meets the requirements of AsyncReadStream and AsyncWriteStream
* Partially supports P1322R0:
"Networking TS enhancement to enable custom I/O executors"
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p1322r0.html
A strand or other io_context-compatible executor may be
chosen to use for all asynchronous stream operations.
* Supports independent timeouts on logical operations:
connect, read, write, or both read and write.
* Provides an option for a configurable rate limit
limit on the maximum rates of reading or writing.
* The previous experimental implementation,
`timeout_socket` and related types, is removed.
* stream_socket is an alias for basic_stream_socket which
uses `net::ip::tcp` as its protocol.
* The function buffers is deprecated, use the new
function make_printable as the replacement.
Actions Required:
* Replace call sites to use make_printable instead of buffers,
and also include make_printable.hpp instead of ostream.hpp.
* Tidy up tests
* Increase code coverage
* Remove move special members
* Correct behavior for default constructed iterators
API Changes:
* buffers_adaptor is renamed (was buffers_adapter)
Actions Required:
* Replace buffers_adapter.hpp with buffers_adaptor.hpp, and
replace buffers_adapter with buffers_adaptor. Or, define
BOOST_BEAST_ALLOW_DEPRECATED
fix#769
The following classes are removed:
* handler_type
* async_result
* async_completion
* is_dynamic_buffer
* is_const_buffer_sequence
* is_mutable_buffer_sequence
* handler_alloc
Actions Required:
* Use BOOST_ASIO_HANDLER_TYPE instead of handler_type
* Use BOOST_ASIO_INITFN_RESULT_TYPE instead of async_result
* Use boost::asio::async_completion
* Use boost::asio::is_dynamic_buffer
* Use boost::asio::is_const_buffer_sequence
* Use boost::asio::is_mutable_buffer_sequence
* boost::asio::associated_allocator_t replaces handler_alloc
fix#773
* buffer_cat is renamed to buffers_cat
* buffer_cat_view is renamed to buffers_cat_view
Actions Required:
* Use buffers_cat instead of buffer_cat
* Use buffers_cat_view instead of buffer_cat_view
fix#773
* buffer_prefix is renamed to buffers_prefix
* buffer_prefix_view is renamed to buffers_prefix_view
Actions Required:
* Use buffers_prefix instead of buffer_prefix
* Use buffers_prefix_view instead of buffer_prefix_view
* The drain_buffer dynamic buffer is no longer a public interface.
Actions Required:
* Replace code which uses drain_buffer. For websocket::stream,
it is no longer necessary to manually drain the connection
after closing.
