* frame_info struct is removed
* read_frame and async_read_frame return a bool indicating
if the frame is the last frame of the current message.
Actions Required:
* Remove the frame_info parameter from all read frame call sites
* Check the return value 'fin' for calls to read_frame
* Change ReadHandlers passed to async_read_frame to have
the signature void(error_code, bool fin), use the bool
to indicate if the frame is the last frame.
fix#446
* Read signatures no longer include `opcode`
* stream::got_binary and stream::got_text inform the caller if
the current incoming message is binary or text.
Actions Required:
* Remove the `opcode` reference parameter from calls to synchronous
and asynchronous read functions, replace the logic with calls to
stream::got_binary and stream::got_text instead.
fix#446
* The ping_callback option struct is removed.
Actions Required:
* Change call sites which use ping_callback with set_option to
call stream::ping_callback instead.
fix#446
* The write_buffer_size option struct is removed.
Actions Required:
* Change call sites which use write_buffer_size with set_option to
call stream::write_buffer_size instead.
fix#446
* The read_message_max option struct is removed.
Actions Required:
* Change call sites which use read_message_max with set_option to
call stream::read_message_max instead.
fix#446
* The read_buffer_size option struct is removed
Actions Required:
* Change call sites which use read_buffer_size with set_option to
call stream::read_buffer_size instead.
fix#446
* message_type is removed
Actions Required:
* Change call sites which use message_type with set_option
to call stream::binary or stream::text instead.
fix#374, fix#446
* auto_fragment option struct is removed
Actions Required:
* Change call sites which use auto_fragment with set_option
to call stream::auto_fragment instead.
fix#440
WARNING
multi_buffer constructor now takes a maximum size instead of the
"allocation size". This is a breaking change. The allocation size
feature is removed. To update calling code, remove the allocation
size parameter from call sites.
* multi_buffer now uses a geometric growth algorithm for better performance.
The static buffer is updated:
* reset() is no longer a member. Use b.consume(b.size()) instead.
* Simplified implementaton, uses asio instead of custom types
* Better stream performance: consuming the input makes room
available in the output. This class is now suitable for
HTTP reads.
These changes permit the static_buffer wrapper to adapt a user
memory buffer if desired, including a stack based array.
The static_buffer_n class may also be used for this purpose,
it comes with its own storage.
fix#431, fix#430
The read_some and async_read_some HTTP operations no longer
return the number of bytes that the caller should consume.
Instead, the bytes are automatically removed from the dynamic
buffer as indicated by the parser.
