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.
* Remove cxx14 compatibility layer from ripple
* Update travis to clang 3.6 and drop gcc 4.8
* Remove unneeded beast CXX14 defines
* Do not run clang build with gdb with travis
* Update circle ci to clang 3.6 & gcc-5
* Don't run rippled in gdb, clang builds crash gdb
* Staticly link libstdc++, boost, ssl, & protobuf
* Support builds on ubuntu 15.10
* Brings the soci subtree into rippled.
* Validator, peerfinder, and SHAMapStore use new soci backend.
* Optional postgresql backend for soci (if POSTGRESQL_ROOT env var is set).
The NuDB database backend is a high performance key/value store presented
as an alternative to RocksDB on Mac and Linux deployments, and the preferred
backend option for Windows deployments. The LevelDB backend is deprecated for
all platforms.
This includes these changes:
* Add Backend::verify API for doing consistency checks
* Add Database::close so caller can catch exceptions
* Improved Timing test for NodeStore creates a simulated workload
* Rename unity files
* Move some modules to new subdirectories
* Remove obsolete Visual Studio project files
* Remove obsolete coding style and TODO list
