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.
Clang does not understand gcc 5's new ABI. On linux systems
that default to the new ABI (such as ubuntu 15.10), building
with clang requires using C++ libraries built with the the old
gcc ABI.
When building with the clang protobuf lib, a common error is to
load the gcc protobuf library at run time. When set, PROTOBUF_ROOT
is added to rpath to make sure the correct lib is loaded.
Adds a script to install clang and download and build boost and
protobuf with boost.
* SConstruct will set ABI based on ubuntu flavor
* Script to bring in packages for various ubuntu flavors
* Script to bring in packages for various fedora 22
* Remove unneeded environment variable from travis
* Script to build boost with correct API flags
* `--static` flag to control static linking
* 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
Member functions and free functions on Ledger and LedgerEntrySet are
rewritten in terms of new abstract interfaces `BasicView` and `View`,
representing the set of non-decomposable primitives necessary to read
and write state map items in a ledger, and to overlay a discardable
view onto a Ledger that can calculate metadata during transaction
processing. const-correctness is enforced through the parameter and
return types.
The MetaView now supports multi-level stacking: A MetaView can be
stacked on top of either a Ledger or another MetaView, up to any
number of levels.
The getSLEi member function is removed. The CachedView wrapper
replaces it, wrapping a View such that any function called with a
CachedView will go through the SLECache.
* Add BasicView, View, CachedView
* Rename LedgerEntrySet to MetaView
* Factor out free functions
* Consolidate free functions in ViewAPI
* Remove unused class members and free functions
This adds "require" functionality which allows invariants
to be checked after processing transactions using a simple,
terse interface. Also adds more comprehensive test coverage
for the framework itself, verifying that the more sophisticated
language constructs work in all ways.
All functions and classes have been split up into individual
files which may be included a-la carte, or accessed through
a single convenience header <ripple/test/jtx.h>
* Move, rename all sources
* Put everything in the jtx namespace
* Add sendmax funclet
* Rename funclet to paths
* Correctly set input issue and destination amount in path
* Conditionally invoke funclets using is_call_possible
* Add any() function means "any currency they will accept"
* Add None, none modifiers on amounts to mean "no amount"
* Add require conditions to JTx
* Add Env::require variadic condition checker
* Add le, rename some items for consistency
* Add require functors, balance, flags, nflags
* Add require functors lines, owners, offers, tickets
* Add ticket example of extending the system
* Add noripple modifier for funding accounst
* Add Env::st to parse Json into STTx
* Add tests to ensure correctness of fund()
* Add virtual Env member hooks
* Add Env::balance
* Add Env::seq
* Add PrettyAmount
* Add all container Account support
* IOU and XRP return PrettyAmount amounts
* IOUs print the issuer's name instead of base58
* Fix int and double conversions to XRP
* Fix autofill of Env::fund with noripple
This adds a suite of tools used to write unit tests. The Env provides
a context containing a ledger, and routines that assemble transactions
from JSON with optional "funclets" that add details in an exensible, terse
notation.
Add support for the SignerListSet transaction as a step toward
multi-sign support.
As part of the SignerListSet implementation, add InnerObjectFormat
templates (similar to TxFormats and LedgerFormats) and enforce them
in STObject, STArray, and STParsedJSON.
* Get classic & unity sources once only
* Use MD5-Timestamp
* Use implicit cache for specific debug builds
* Skip prep work for targets what will not be built
Changes made to support autobridging and improve the offer-crossing and
pathfinding logic result in transaction-breaking changes which cause
incompatibilities between 0.27 and 0.28 builds of RippleD.
This patch simplifies deployment of 0.28 on the Ripple network by allowing
RippleD to emulate the 0.27 semantics while the last closed ledger closed
before March 30, 2015 at 13:00:00 PDT, after which time the new 0.28
semantics will become active.
The transaction-breaking changes addressed in this commit are:

The LevelDB and HyperLevelDB are removed from the backend choices. Neither
were recommended for production environments. As RocksDB is not available
on Windows platforms yet, the recommended backend choice for Windows is NuDB.
When sql tries to acquire a lock that is already held, it sleeps for some
microseconds using the usleep function and then try to acquire the lock
again. However, if the HAVE_USLEEP macro is not defined then the sleep
function will be used.
This fix will define HAVE_USLEEP even when it is not already defined by
the system. Although some Linux distros may not define HAVE_USLEEP,
all supported versions provide usleep. If the system does not actually
have a usleep function, then the compiler will flag the error.
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
