* `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#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#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.
* 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.
fix#1290
* BOOST_ASIO_NO_DEPRECATED=1 is now set
* Fix various warnings from the Boost regression test matrix
* Fix a bug in advanced servers when checking for a timeout
fix#1113
This solves a problem where the message-oriented synchronous
HTTP write algorithms do not support messages whose body
writer requires a non-const reference to the message in
order to construct.
In addition, the message-oriented async_write algorithm is
modified to support messages passed by const reference when
possible, based on the body writer attributes.
fix#884
* BodyReader and BodyWriter constructors now require the header and
body elements to be passed as distinct header and value_type objects.
This enables the composition of body types, for example:
http::response<compressed_body<http::string_body>> res;
* The previous single-argument constructors are deprecated and will be
removed in a subsequent version.
Actions Required:
* Change user-defined instances of BodyReader or BodyWriter constructor
signatures to the two-argument form.
OR
* Define the macro BOOST_BEAST_ALLOW_DEPRECATED in the project (which
will accept both the new and the deprecated signatures).
Body::reader and Body::writer meanings are reversed, for
consistency with the names of the stream operations:
* Body::reader is used for read, read_some, async_read, async_read_some
* Body::writer is used for write, write_some, async_write, async_write_some
Actions Required:
* Swap the reader and writer names for user defined Body types
* Swap use of is_body_reader and is_body_writer
Some `basic_parser` member functions are renamed:
* chunked() was is_chunked()
* upgrade() was is_upgrade()
* keep_alive() was is_keep_alive()
Actions Required:
* Rename member function invocations at call sites
* The function has_content_length_impl is added to the
requirements of Fields.
Actions Required:
* Implement has_content_length_impl for user-defined Fields
fix#769
The following classes are removed:
* handler_type
* async_result
* async_completion
* is_dynamic_buffer
* is_const_buffer_sequence
* is_mutable_buffer_sequence
* handler_alloc
Actions Required:
* Use BOOST_ASIO_HANDLER_TYPE instead of handler_type
* Use BOOST_ASIO_INITFN_RESULT_TYPE instead of async_result
* Use boost::asio::async_completion
* Use boost::asio::is_dynamic_buffer
* Use boost::asio::is_const_buffer_sequence
* Use boost::asio::is_mutable_buffer_sequence
* boost::asio::associated_allocator_t replaces handler_alloc
fix#767
The write family of HTTP stream algorithms no longer returns
error::end_of_stream when the message indicates that the connection
should be closed.
Actions Required:
* Add code to servers to close the connection after successfully
writing a message where `message::keep_alive()` would return `false`.
