permessage-deflate is a compile-time feature (API Change): fix #849 This adds an additional `bool` template parameter to `websocket::stream`: * When deflateSupported is `true`, the stream will be capable of negotiating the permessage-deflate websocket extension per the configured run-time settings. * When deflateSupported is `false`, the stream will never negotiate the permessage-deflate websocket extension. Furthermore, all of the code necessary for implementing the permessage-deflate extension will be excluded from function instantiations. The resulting emitted object code should be smaller.

New HTTP interfaces (API Change): fix #123 fix #154 fix #265 This completely replaces the HTTP parser used to read and parse incoming messages. The new version is faster than the old one, and written in fewer lines. A summary of changes: * parse and async_parse renamed to read and async_read * basic_parser is optimized for linear buffers, use flat_streambuf for the best performance with these functions: - http::read - http::read_some - http::async_read - http::async_read_some * The overloads of read() and async_read() which take just a header have been removed, since they would throw away important parse metadata. * The derived class callbacks for basic_parser have been streamlined. All strings passed to callbacks are presented in their entirety, instead of being provided in pieces. These changes allow use-cases that were previously difficult or impossible, such as: - Efficient relaying - Late body type commitment - Expect: 100-continue handling

Refactor websocket decorators (API Change): fix #80, #212, fix #303, fix #314, fix #317 websocket::stream now provides the following families of functions for performing handshakes: When operating in the server role: * stream::accept * stream::accept_ex * stream::async_accept * stream::async_accept_ex When operating in the client role: * stream::handshake * stream::handshake_ex * stream::async_handshake * stream::async_handshake_ex Member functions ending with "_ex" allow an additional RequestDecorator parameter (for the accept family of functions) or ResponseDecorator parameter (for the handshake family of functions). The decorator is called to optionally modify the contents of the HTTP request or HTTP response object generated by the implementation, before the message is sent. This permits callers to set the User-Agent or Server fields, add or modify HTTP fields related to subprotocols, or perform any required transformation of the HTTP message for application-specific needs. The handshake() family of functions now have an additional set of overloads accepting a parameter of type response_type&, allowing the caller to receive the HTTP Response to the Upgrade handshake. This permits inspection of the response to handle things like subprotocols, authentication, or other application-specific needs. The new implementation does not require any state to be stored in the stream object. Therefore, websocket::stream objects are now smaller in size. The overload of set_option for setting a decorator on the stream is removed. The only way to set decorators now is with a suitable overload of accept or handshake.

Refactor websocket decorators (API Change): fix #80, #212, fix #303, fix #314, fix #317 websocket::stream now provides the following families of functions for performing handshakes: When operating in the server role: * stream::accept * stream::accept_ex * stream::async_accept * stream::async_accept_ex When operating in the client role: * stream::handshake * stream::handshake_ex * stream::async_handshake * stream::async_handshake_ex Member functions ending with "_ex" allow an additional RequestDecorator parameter (for the accept family of functions) or ResponseDecorator parameter (for the handshake family of functions). The decorator is called to optionally modify the contents of the HTTP request or HTTP response object generated by the implementation, before the message is sent. This permits callers to set the User-Agent or Server fields, add or modify HTTP fields related to subprotocols, or perform any required transformation of the HTTP message for application-specific needs. The handshake() family of functions now have an additional set of overloads accepting a parameter of type response_type&, allowing the caller to receive the HTTP Response to the Upgrade handshake. This permits inspection of the response to handle things like subprotocols, authentication, or other application-specific needs. The new implementation does not require any state to be stored in the stream object. Therefore, websocket::stream objects are now smaller in size. The overload of set_option for setting a decorator on the stream is removed. The only way to set decorators now is with a suitable overload of accept or handshake.

WebSocket Decorator is a socket option (API Change): This changes the interface used to apply a decorator to the HTTP request or response messages used to perform the WebSocket handshake as follows: * Add the `stream_base::decorator` option object * Add `stream::set_option` overload to set the decorator from the option * The decorator applies to all client and server handshakes performed on the stream after the option is set. * Overloads of the following functions which accept a Decorator are deprecated: - accept, accept_ex - handshake, handshake_ex - async_accept, async_accept_ex - async_handshake, async_handshake_ex Actions Required: * Code which passes decorator to any `websocket::stream` member function should call `stream::set_option` instead with a newly constructed `stream_base::decorator` object containing the decorator. Alternatively, the macro `BOOST_BEAST_ALLOW_DEPRECATED` may be defined to 1.
