In support of dynamic validator list, this changeset:
1. Adds a new `validator_list_expires` field to `server_info` that
indicates when the current validator list will become stale.
2. Adds a new admin only `validator_lists` RPC that returns the
current list of known validators and the most recent published validator
lists.
3. Adds a new admin only `validator_sites` RPC that returns the list of
configured validator publisher sites and when they were most recently
queried.
* RPC `ledger` command returns all queue entries in "queue_data"
when requesting open ledger, and including boolean "queue: true".
* Includes queue state. e.g.: fee_level, retries, last_result, tx.
* Respects "expand" and "binary" parameters for the txs.
* Remove some unused code.
Payment channels permit off-ledger checkpoints of XRP payments flowing
in a single direction. A channel sequesters the owner's XRP in its own
ledger entry. The owner can authorize the recipient to claim up to a
give balance by giving the receiver a signed message (off-ledger). The
recipient can use this signed message to claim any unpaid balance while
the channel remains open. The owner can top off the line as needed. If
the channel has not paid out all its funds, the owner must wait out a
delay to close the channel to give the recipient a chance to supply any
claims. The recipient can close the channel at any time. Any transaction
that touches the channel after the expiration time will close the
channel. The total amount paid increases monotonically as newer claims
are issued. When the channel is closed any remaining balance is returned
to the owner. Channels are intended to permit intermittent off-ledger
settlement of ILP trust lines as balances get substantial. For
bidirectional channels, a payment channel can be used in each direction.
The new code removes the ability to specify domain names
in the [validators] configuration block, and no longer
supports the [validators_site] option.
More details on the supported configurations are available
under doc/rippled-example.cfg.
The first few transactions are added to the open ledger at
the base fee (ie. 10 drops). Once enough transactions are
added, the required fee will jump dramatically. If additional
transactions are added, the fee will grow exponentially.
Transactions that don't have a high enough fee to be applied to
the ledger are added to the queue in order from highest fee to
lowest. Whenever a new ledger is accepted as validated, transactions
are first applied from the queue to the open ledger in fee order
until either all transactions are applied or the fee again jumps
too high for the remaining transactions.
Current implementation is restricted to one transaction in the
queue per account. Some groundwork has been laid to expand in
the future.
Note that this fee logic escalates independently of the load-based
fee logic (ie. LoadFeeTrack). Submitted transactions must meet
the load fee to be considered for the queue, and must meet both
fees to be put into open ledger.
Eventually multisign will need to be enabled onto the network, at
which point compiling it in or out will no longer be an option.
In preparation, the compile guards are removed and multisign is
being enabled with a Feature.
You can locally enable a Feature using your config file. To
enable multisign with your config file add a section like this:
[features]
MultiSign
The exact spelling and capitalization of both "features" and
"MultiSign" is important. If you don't get those right multisign
will not be enabled.
There is a minor issue. The "sign_for" and "submit_multisigned"
RPC commands are only enabled if multisign is enabled. However
those commands are still shown in the help message even if
multisign is disabled. This is because the code that produces
the help message doesn't read the config file (where the Features
are kept). This problem will become irrelevant once multisign is
enabled onto the network.
This commit provides support for 2-level multi-signing of
transactions. The ability is usually compiled out, since other
aspects of multi-signing are not yet complete.
Here are the missing parts:
o Full support for Tickets in transactions.
o Variable fees based on the number of signers,
o Multiple SignerLists with access control flags on accounts,
o Enable / disable operations based on access control flags,
o Enable / disable all of multi-signing based on an amendment,
o Integration tests, and
o Documentation.
* Remove the deprecated wallet_accounts command.
* Remove dead code for generator maps.
* Remove the help for the obsolete wallet_add and wallet_claim commands
(which have already been removed).
This enhances the reporting capability of RPC::LookupLedger and reduces
the requirement of a current ledger for many RPC commands.
The perceived up-time of client handlers improves since requests will
not depend on the server being fully synced.
General RPC command that can retrieve objects in the account root.
* Add account objects integration test.
* Support tickets.
* Add removeElement in Json::Value
To help gateways make the changes needed to adjust to the
"default ripple" flag, we've added the "noripple_check"
RPC command. This command tells gateways what they need
to do to set this flag and fix any trust lines created
before they set the flag.
Once your server is running and synchronized, you can run
the tool from the command line with a command like:
rippled json noripple_check '
{
"account" : "<gateway_trusted_address_here>",
"role" : "gateway",
"transactions" : "true"
}'
The server will respond with a list of "problems" that it
sees with the configuration of the account and its trust
lines. It will also return a "transactions" array suggesting
the transactions needed to fix the problems it found.
An alternative to the unity build, the classic build compiles each
translation unit individually. This adds more modules to the classic build:
* Remove unity header app.h
* Add missing includes as needed
* Remove obsolete NodeStore backend code
* Add app/, core/, crypto/, json/, net/, overlay/, peerfinder/ to classic build
Makes rippled configurable to support deletion of all data in its key-value
store (nodestore) and ledger and transaction SQLite databases based on
validated ledger sequence numbers. All records from a specified ledger
and forward shall remain available in the key-value store and SQLite, and
all data prior to that specific ledger may be deleted.
Additionally, the administrator may require that an RPC command be
executed to enable deletion. This is to align data deletion with local
policy.
This changes the behavior and configuration specification of the listening
ports that rippled uses to accept incoming connections for the supported
protocols: peer (Peer Protocol), http (JSON-RPC over HTTP), https (JSON-RPC)
over HTTPS, ws (Websockets Clients), and wss (Secure Websockets Clients).
Each listening port is now capable of handshaking in multiple protocols
specified in the configuration file (subject to some restrictions). Each
port can be configured to provide its own SSL certificate, or to use a
self-signed certificate. Ports can be configured to share settings, this
allows multiple ports to use the same certificate or values. The list of
ports is dynamic, administrators can open as few or as many ports as they
like. Authentication settings such as user/password or admin user/admin
password (for administrative commands on RPC or Websockets interfaces) can
also be specified per-port.
As the configuration file has changed significantly, administrators will
need to update their ripple.cfg files and carefully review the documentation
and new settings.
Changes:
* rippled-example.cfg updated with documentation and new example settings:
All obsolete websocket, rpc, and peer configuration sections have been
removed, the documentation updated, and a new documented set of example
settings added.
* HTTP::Writer abstraction for sending HTTP server requests and responses
* HTTP::Handler handler improvements to support Universal Port
* HTTP::Handler handler supports legacy Peer protocol handshakes
* HTTP::Port uses shared_ptr<boost::asio::ssl::context>
* HTTP::PeerImp and Overlay use ssl_bundle to support Universal Port
* New JsonWriter to stream message and body through HTTP server
* ServerHandler refactored to support Universal Port and legacy peers
* ServerHandler Setup struct updated for Universal Port
* Refactor some PeerFinder members
* WSDoor and Websocket code stores and uses the HTTP::Port configuration
* Websocket autotls class receives the current secure/plain SSL setting
* Remove PeerDoor and obsolete Overlay peer accept code
* Remove obsolete RPCDoor and synchronous RPC handling code
* Remove other obsolete classes, types, and files
* Command line tool uses ServerHandler Setup for port and authorization info
* Fix handling of admin_user, admin_password in administrative commands
* Fix adminRole to check credentials for Universal Port
* Updated Overlay README.md
* Overlay sends IP:port redirects on HTTP Upgrade peer connection requests:
Incoming peers who handshake using the HTTP Upgrade mechanism don't get
a slot, and always get HTTP Status 503 redirect containing a JSON
content-body with a set of alternate IP and port addresses to try, learned
from PeerFinder. A future commit related to the Hub and Spoke feature will
change the response to grant the peer a slot when there are peer slots
available.
* HTTP responses to outgoing Peer connect requests parse redirect IP:ports:
When the [overlay] configuration section (which is experimental) has
http_handshake = 1, HTTP redirect responses will have the JSON content-body
parsed to obtain the redirect IP:port addresses.
* Use a single io_service for HTTP::Server and Overlay:
This is necessary to allow HTTP::Server to pass sockets to and from Overlay
and eventually Websockets. Unfortunately Websockets is not so easily changed
to use an externally provided io_service. This will be addressed in a future
commit, and is one step necessary ease the restriction on ports configured
to offer Websocket protocols in the .cfg file.
