These changes prepare Overlay for the Universal Port and Hub and Spoke
features.
* Add [overlay configuration section:
The [overlay] section uses the new BasicConfig interface that
supports key-value pairs in the section. Some exposition is added to the
example cfg file. The new settings for overlay are related to the Hub and
Spoke feature which is currently in development. Production servers should
not set these configuration options, they are clearly marked experimental
in the example cfg file.
Other changes:
* Use _MSC_VER to detect Visual Studio
* Use ssl_bundle in Overlay::Peer
* Use shared_ptr to SSL context in Overlay:
* Removed undocumented PEER_SSL_CIPHER_LIST configuration setting
* Add Section::name: The Section object now stores its name for better diagnostic messages.
This is a cleanup to the structure of the sources.
* Rename to ServerHandler
* Move private implementation declaration to separate header
* De-inline function definitions in the class declaration.
Many classes required to support type-erasure of handlers and boost::asio
types are now obsolete, so these classes and files are removed:
HTTPClientType, FixedInputBuffer, PeerRole, socket_wrapper,
client_session, basic_url, abstract_socket, buffer_sequence, memory_buffer,
enable_wait_for_async, shared_handler, wrap_handler, streambuf,
ContentBodyBuffer, SSLContext, completion-handler based handshake detectors.
These structural changes are made:
* Some missing includes added to headers
* asio module directory flattened
The implementation of multi-sign has a SigningAccounts array as a
member of the outermost object. This array could not be parsed
by the previous implementation of STParsedJSON, which only knew
how to parse objects. This refactor supports the required parsing.
The refactor divides the parsing into three separate functions:
o parseNoRecurse() which parses most rippled data types.
o parseObject() which parses object types that may contain
arbitrary other types.
o parseArray() which parses object types that may contain
arbitrary other types.
The change is required by the multi-sign implementation, but is
independent. So the parsing change is going in as a separate
commit.
The parsing is still far from perfect. But this was as much as
needs doing to accomplish the ends and mitigate risk of breaking
the parser.
* More fine-grained Section mutators
* Add remap for mapping legacy single sections to key value pairs
* Add output stream operators for BasicConfig and Section
* Allow section values to be overwritten from command line
* Update rpc key/value configs from command line
* Add RPC::Setup with defaults and remap legacy rpc sections
