* `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`.
fix#38
This improves the behavior when encountering a short read:
* Any stream error encountered during a read is converting into
`http::error::partial_message` if some data was received but
the message is incomplete.
* Examples squelch SSL short read errors from the logs.
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.
fix#1435, fix#1438
* Example and test can be built on msvc v141 15.9.6
using /std:c++17 and BOOST_BEAST_USE_STD_STRING_VIEW.
* changed string_view.to_string() to std:string(string_view),
awaiting availability of Library Fundamentals TS here.
* Reactivated relevant tests to param_list. #ifdef 0 test
exhibited same assertion failed error in debug mode.
Now fixed in DEBUG on msvc v141 15.9.6 with
BOOST_BEAST_USE_STD_STRING_VIEW and /std:c++17.
* Looked up http paramters (transfer-encoding, etc.)
and changed tests as well as fixing comment to
match specs.
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.
