buffers_generator uses default_completion.
websocket::stream has a rebinding constructor.
ssl_stream has a rebind_executor member.
basic_stream has rebinding constructor.
- websocket supports cancellation.
- Iterating test for ws cancellation.
- Only terminal cancellation is forwarded by default.
- basic_stream supports cancellation.
- supported cancellation is documented.
- http cancellation additions.
- Added cancellation_slot tests to http, utils and saved_handler.
- Added post to write.cpp, to avoid SIGSEV in test.
- Refresher describes cancellation in more detail.
API Changes:
* The following deprecated functions have been removed:
- websocket::async_accept_ex
- websocket::async_handshake_ex
- websocket::accept_ex
- websocket::handshake_ex
Programs still using these names should be refactored to use the `decorator` feature and
the remaining handshake and accept functions.
refs #1934
C++14 or later is required to support completion tokens that use
per-operation return type deduction. For C++11, a completion
token's async_result specialisation must still provide the nested
typedef `return_type`.
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.
* 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
The nested function lowest_layer and nested type lowest_layer_type
are removed from all stream layers.
Actions Required:
* Remove lowest_layer and lowest_layer_type from user-defined streams.
* Use the get_lowest_layer free function and the lowest_layer_type trait
as needed.
* Tidy up and comment asserts
* `pausation` is renamed to saved_handler
* A work guard on the handler's associated executor
is maintained for the lifetime of the store handler.
fix#1279, close#1319
This enables users to improve compilation performance by explicitly
instantiating the stream template in another TU.
