fix#80, #212, fix#303, fix#314, fix#317
websocket::stream now provides the following families of
functions for performing handshakes:
When operating in the server role:
* stream::accept
* stream::accept_ex
* stream::async_accept
* stream::async_accept_ex
When operating in the client role:
* stream::handshake
* stream::handshake_ex
* stream::async_handshake
* stream::async_handshake_ex
Member functions ending with "_ex" allow an additional
RequestDecorator parameter (for the accept family of
functions) or ResponseDecorator parameter (for the
handshake family of functions).
The decorator is called to optionally modify the contents
of the HTTP request or HTTP response object generated by
the implementation, before the message is sent. This
permits callers to set the User-Agent or Server fields,
add or modify HTTP fields related to subprotocols, or
perform any required transformation of the HTTP message
for application-specific needs.
The handshake() family of functions now have an additional
set of overloads accepting a parameter of type response_type&,
allowing the caller to receive the HTTP Response to the
Upgrade handshake. This permits inspection of the response
to handle things like subprotocols, authentication, or
other application-specific needs.
The new implementation does not require any state to be
stored in the stream object. Therefore, websocket::stream
objects are now smaller in size.
The overload of set_option for setting a decorator on the
stream is removed. The only way to set decorators now is
with a suitable overload of accept or handshake.
This adds enough functions to the accept and async_accept
overload set to cover all combinations of request, buffers,
and error_code parameters. This also fixes a defect where
providing a complete Upgrade request when there are additional
unprocessed octets remaining in the callers stream buffer
could not be furnished to the WebSocket implementation.
fix#127
* Added beast::detail::ignore_unused based on boost::ignore_unused
* Added -Wextra compilation flag when building with gcc
* Fixed all unused parameter warnings with ignore_unused
* Fixed all missing includes when building each .hpp separately
This solves a problem where clang and gcc locate the deleted
version of teardown and async_teardown instead of the overloaded
version. It requires overloads to add `teardown_tag` into the signature
so that the rules for argument dependent lookup can find the
right function. Improve documentation of teardown requirements
The documentation is updated to clearly explain the need for including
<beast/websocket/ssl.hpp> to use SSL streams with WebSocket.
The default implementations of teardown and async_teardown now use
static_assert to alert the user of improper usage, with comments
providing guidance for resolving the error.
New parser set_option function for controlling independent size limits
on headers and body. By default request and response parsers are set up
with reasonable limits to prevent resource exhaustion attacks.
* Parser adheres strictly to rfc7230
* Increased test coverage
* Headers and body maximum size limit options
* Improve test coverage
* tests for invokable in composed ops
* Update documentation
* Add License badge to README
* Target Windows 7 SDK and later
* Make role_type private
* Remove extra unused masking functions
* Allow stream reuse / reconnect after failure
* Restructure logic of composed operations
* Allow 0 for read_message_max meaning no limit
* Respect keep alive when building HTTP responses
* Check version in upgrade request
* Response with 426 status on unsupported WebSocket version
* Remove unnecessary Sec-WebSocket-Key in HTTP responses
* Rename to mask_buffer_size
* Remove maybe_throw
* Add ping, async_ping, async_on_pong
* Add ping_op
* Add pong_op
* Fix crash in accept_op
* Fix suspend in close_op
* Fix read_frame_op logic
* Fix crash in read_op
* Fix races in echo sync and async echo servers
Core:
* Test buffer_cat iterator move members
HTTP:
* Fixed yield / resume in writer
* Fixed message serialization with chunked encoding
* Test yield / resume in writer
* Test all conditional branches during message serialization
* Test chunked encoding
* Increase coverage on parse_error
* Add parse_error::general
WebSocket:
* Add error::general
* Increase coverage in error
