Beast.WebSocket provides developers with a robust WebSocket
implementation built on Boost.Asio with a consistent asynchronous
model using a modern C++ approach.
New classes are introduced to represent HTTP messages and their
associated bodies. The parser interface is reworked to use CRTP,
error codes, and trait checks.
New classes:
* basic_headers
Models field/value pairs in a HTTP message.
* message
Models a HTTP message, body behavior defined by template argument.
Parsed message carries metadata generated during parsing.
* parser
Produces parsed messages.
* empty_body, string_body, basic_streambuf_body
Classes used to represent content bodies in various ways.
New functions:
* read, async_read, write, async_write
Read and write HTTP messages on a socket.
New concepts:
* Body: Represents the HTTP Content-Body.
* Field: A HTTP header field.
* FieldSequence: A forward sequence of fields.
* Reader: Parses a Body from a stream of bytes.
* Writer: Serializes a Body to buffers.
basic_parser changes:
* add write methods which throw exceptions instead
* error_code passed via parameter instead of return value
* fold private member calls into existing callbacks
* basic_parser uses CRTP instead of virtual members
* add documentation on Derived requirements for CRTP
impl/http-parser changes:
* joyent renamed to nodejs to reflect upstream changes
New classes:
class async_completion:
Helper class for implementing asynchronous initiation functions.

class basic_streambuf:
Meets the requirements of Streambuf.
class buffered_readstream:
Buffers a ReadStream with a ConstBufferSequence.
class consuming_buffers:
Adapts a BufferSequence which wraps the underlying buffer
sequence and presents fewer bytes, with the retained bytes
occurring at the end of the sequence.
class handler_alloc:
A C++ Allocator the uses asio handler allocation hooks.
class static_streambuf:
An implementation of the Streambuf concept that uses a
fixed size buffer with size determined at compile-time.
class streambuf_readstream:
Buffers a ReadStream with a Streambuf.
New functions:
append_buffers()
Returns a new BufferSequence which efficiently concatenates
two or more buffer sequences together.
prepare_buffers()
Shortens a buffer sequence. The bytes excluded are at the
end of the underlying buffer sequence.
boost::asio::read_until()
A copy of boost::asio::read_until overloads, modified to work
with a beast::asio::basic_streambuf.
Debugging:
buffers_to_string()
Convert a ConstBufferSequence to a human readable string
suitable for diagnostics.
type_check.h:
Metafunctions for checking asio concepts:
AsyncReadStream, AsyncWriteStream
SyncReadStream, SyncWriteStream
ConstBufferSequence, MutableBufferSequence
Streambuf
Handler
Changes:
* All symbols moved up a namespace level.
* streambuf provides all move and copy special members,
behavior of moved from objects is well-defined.
Fixes:
* Fix basic_streambuf iterator category.
Calculate the number of file descriptors that are needed during
execution based on the configuration file, with a hard floor
of 1024, adjusting the limit if possible. Refuse to run if enough
fds are not available.
Additionally, allow administrators to limit the number of incoming
connections a configured port will accept. By default no limit is
imposed.
Replace Journal public data members with member function accessors
in order to make Journal lighter weight. The change makes a
Journal cheaper to pass by value.
Also add missing stream checks (e.g., calls to JLOG) to avoid
text processing that ultimately will not be stored in the log.
The IP address used to perform pathfinding operations is now charged an
additional resource increment for each source currency in the path set.
* NOTE: This charge is a local resource charge, not a transaction fee
charge.
The Journal API is affected. There are two uses for the
Journal::Severity enum:
o It is used to declare a threshold which log messages must meet
in order to be logged.
o It declares the current logging level which will be compared
to the threshold.
Those uses that affect the threshold are now named threshold()
rather than severity() to make the uses easier to distinguish.
Additionally, Journal no longer carries a Severity variable.
All handling of the threshold() is now delegated to the
Journal::Sink.
Sinks are no longer constructed with a default threshold of
kWarning; their threshold must be passed in on construction.
Class io_list manages children that perform asynchronous
I/O operations. The treatment of close and destruction is
refactored to fix race conditions during exit.
This is designed for use by proxies in front of rippled. Configured IPs
can forward identifying user data in HTTP headers, including
user name and origin IP. If the user name exists, then resource limits
are lifted for that session. However, administrative commands are still
reserved only for administrative sessions.
