The ANDROID define us usually originationg from he build system
(like CMake, ndk-build, etc.). But some buildsystems like Bazel
do not set it which brakes Android platform detection.
Better use __ANDROID__ (like boost predef does) which is
predefined by the compiler if targeting Android.
* 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.
* `basic_parser` now uses pure virtual member functions instead
of the curiously recurring template pattern.
Actions Required:
* Change uses of the `basic_parser` type to omit the `Derived`
template parameter
* Classes derived from `basic_parser` no longer need to friend
the base.
* Virtual functions in the derived class may be marked `override`.
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.
