fix#1416
* Calls to buffer_copy are qualified as net::buffer_copy
* Calls to buffer_size are made unqualified, permitting
argument dependent lookup to take effect.
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.
fix#1365
To reduce instantiations, the list of template parameters
to the bind and bind_front handler wrappers are decayed before
naming the class template.
* Tidying
* Increase test coverage
* Fix file_mode::append_existing
API Changes:
* file_mode::append_new is removed, as it makes no sense
Actions Required:
* Replace file_mode::append_new with file_mode::append
or file_mode::append_existing instead of file_mode::append_new
* 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.
* Improved tests
* Refactor some declaration material
* basic_multi_buffer::clear is public
and
* Fix flat_buffer::reserve
* flat_buffer::clear is public
When BOOST_BEAST_TESTS is not defined, violations of
buffers_cat preconditions will assert instead of throwing
exceptions. This reduces the size of the emitted code
and improves performance.
Elements of zero size are correctly skipped during iteration.
* Tidy up tests
* Increase code coverage
* Remove move special members
* Correct behavior for default constructed iterators
* 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
fix#1356
* File functions return errc::bad_file_descriptor
instead of errc::invalid_argument.
Actions Required:
* Callers checking for errc::invalid_argument from calls to
file APIs should check for errc::bad_file_descriptor instead.
