* 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.
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.
* 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
This algorithm allows a socket-like object to be closed in
a generic context. The customization point enables user-defined
types to define the close algorithm to use with `close_socket`.
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.
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.
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
This works similarly to bind_handler, and can help with reducing
template instantiations and compiler memory usage (since it does
not need to support placeholders).
A specialization for the most common case `void(error_code, size_t)`
is provided to minimize instantiation cost.
