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
* Revise stream algorithm javadocs
* HTTP stream algorithms now use beast::read and
beast::async_read with a custom completion condition.
API Changes:
* HTTP stream algorithms return the number of bytes transferred
from the stream. Previously, they returned the number of bytes
consumed by the parser.
Actions Required:
* Callers depending on the return value of http::read or
http::async_read overloads should adjust the usage of
the returned value as needed.
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.
fix#1270
basic_fields::value_type uses base hooks instead of member hooks,
otherwise MSVC can sometimes produce undefined behavior when
attempting to recover the base class from a data member in
certain build configurations.
fix#1133, fix#1241
When the macro BOOST_BEAST_USE_STD_STRING_VIEW is defined,
Beast will use std::string_view instead of boost::string_view.
The name boost::beast::string_view is a type alias for the
chosen view type.
fix#1237
HTTP client examples now verify the server's certificate
and generate an error if the certificate is invalid or
expired:
* Set certificate verify mode
* Remove duplicate root certificate
