* If multiple transactions are queued for the account, change the
account's sequence number in a temporary view before processing the
transaction.
* Adds a new "at()" interface to STObject which is identical to the
operator[], but easier to write and read when dealing with ptrs.
* Split the TxQ tests into two suites to speed up parallel run times.
This commit introduces a new configuration option that server
operators can set. The value is communicated to other servers
and is also reported via the `server_info` API.
The value is meant to allow third-party applications or tools
to group servers together. For example, a tool that visualizes
the network's topology can group servers together.
Similar to the "Domain" field in validator manifests, an operator
can claim any domain. Prior to relying on the value returned, the
domain should be verified by retrieving the xrp-ledger.toml file
from the domain and looking for the server's public key in the
`nodes` array.
Use C++17 constant expressions to calculate the inverse
alphabet map at compile time instead of at runtime.
Remove support for encoding & decoding tokens using the
Bitcoin alphabet.
The "/vl" HTTP endpoint can be used to request a particular
UNL from a rippled instance.
This commit, if merged, includes the public key of the requested
list in the response.
This commit fixes#3392
Tickets are a mechanism to allow for the "out-of-order" execution of
transactions on the XRP Ledger.
This commit, if merged, reworks the existing support for tickets and
introduces support for 'ticket batching', completing the feature set
needed for tickets.
The code is gated under the newly-introduced `TicketBatch` amendment
and the `Tickets` amendment, which is not presently active on the
network, is being removed.
The specification for this change can be found at:
https://github.com/xrp-community/standards-drafts/issues/16
This change can help improve the liveness of the network during periods of network
instability, by allowing the network to track which validators are presently not online
and to disregard them for the purposes of quorum calculations.
If the 'HardenedValidations' amendment is enabled, this commit will
track the version of the software that validators embed in their
validations.
If a server notices that at least 60% of the validators on its UNL
are running a newer version than it is running, it will periodically
print an informational message, reminding the operator to check for
update.
The tecUNFUNDED code is actively used when attempting to create payment
channels; the messages incorrectly list it as deprecated.
Meanwhile, the tecUNFUNDED_ADD code actually is an unused legacy code,
dating back to when there was a WalletAdd transactor. The terLAST and
terFUNDS_SPENT codes are also unused legacy codes.
Engine result messages are not part of the binary format and are
documented as subject to change without notice, so this should not
require an amendment nor a new API version.
Align error code table for human readability.
The amendment was partially complete, included no functional code
and, even if activated, it would result in no changes to transaction
proessing. Despite this, removing the amendment is the prudent course
of action and avoids the possibility of an accidental activation.
If additional cryptoconditions are implemented, they will be each
assigned a new, unique amendment code.
* The amendment ballot counting code contained a minor technical
flaw, caused by the use of integer arithmetic and rounding
semantics, that could allow amendments to reach majority with
slightly less than 80% support. This commit introduces an
amendment which, if enabled, will ensure that activation
requires at least 80% support.
* This commit also introduces a configuration option to adjust
the amendment activation hysteresis. This option is useful on
test networks, but should not be used on the main network as
is a network-wide consensus parameter that should not be
changed on a per-server basis; doing so can result in a
hard-fork.
Fixes#3396
Work on a version 2 of the XRP Network API has begun. The new
API returns:
* `notSynced` in place of `noClosed`, `noCurrent`, and `noNetwork`;
* `invalidParams` in place of `lgrIdxInvalid`.
The new version 2 API cannot be selected yet, as it remains a work
in progress.
Fixes#3269
If a port number is not specified in the [ips] or [ips_fixed]
blocks, automatically add the new default peer port which was
registered with IANA: 2459. Also use 2459 if no port is specified
with manually using the `connect` command; previously it was
using 6561, which could have resulted in spurious failures.
This commit, if merged, fixes#2861.
* Make sure variables are always initialized
* Use lround instead of adding .5 and casting
* Remove some unneeded vars
* Check for null before calling strcmp
* Remove redundant if conditions
* Remove make_TxQ factory function
Identifiers for retired amendments should not generally be used
in the codebase.
This commit reduces their visibility down to one translation
unit and marks them as unused and deprecated to prevent
accidental reuse.
In deciding whether to relay a proposal or validation, a server would
consider whether it was issued by a validator on that server's UNL.
While both trusted proposals and validations were always relayed,
the code prioritized relaying of untrusted proposals over untrusted
validations. While not technically incorrect, validations are
generally more "valuable" because they are required during the
consensus process, whereas proposals are not, strictly, required.
The commit introduces two new configuration options, allowing server
operators to fine-tune the relaying behavior:
The `[relay_proposals]` option controls the relaying behavior for
proposals received by this server. It has two settings: "trusted"
and "all" and the default is "trusted".
The `[relay_validations]` options controls the relaying behavior for
validations received by this server. It has two settings: "trusted"
and "all" and the default is "all".
This change does not require an amendment as it does not affect
transaction processing.
The sfLedgerSequence field is designated as optional in the object
template but it is effectively required and validations which do not
include it were, correctly, rejected.
This commit migrates the check outside of the peer code and into the
constructor used for validations being deserialized for the network.
Furthermore, the code will generate an error if a validation that is
generated by a server does not include the field.
Entries in the ledger are located using 256-bit locators. The locators
are calculated using a wide range of parameters specific to the entry
whose locator we are calculating (e.g. an account's locator is derived
from the account's address, whereas the locator for an offer is derived
from the account and the offer sequence.)
Keylets enhance type safety during lookup and make the code more robust,
so this commit removes most of the earlier code, which used naked
uint256 values.
This commit removes obsolete comments, dead or no longer useful
code, and workarounds for several issues that were present in older
compilers that we no longer support.
Specifically:
- It improves the transaction metadata handling class, simplifying
its use and making it less error-prone.
- It reduces the footprint of the Serializer class by consolidating
code and leveraging templates.
- It cleanups the ST* class hierarchy, removing dead code, improving
and consolidating code to reduce complexity and code duplication.
- It shores up the handling of currency codes and the conversation
between 160-bit currency codes and their string representation.
- It migrates beast::secure_erase to the ripple namespace and uses
a call to OpenSSL_cleanse instead of the custom implementation.
Currently there is no mechanism for a validator to report the
version of the software it is currently running. Such reports
can be useful for those who are developing network monitoring
dashboards and server operators in general.
This commit, if merged, defines an encoding scheme to encode
a version string into a 64-bit unsigned integer and adds an
additional optional field to validations.
This commit piggybacks on "HardenedValidations" amendment to
determine whether version information should be propagated
or not.
The general encoding scheme is:
XXXXXXXX-XXXXXXXX-YYYYYYYY-YYYYYYYY-YYYYYYYY-YYYYYYYY-YYYYYYYY-YYYYYYYY
X: 16 bits identifying the particular implementation
Y: 48 bits of data specific to the implementation
The rippled-specific format (implementation ID is: 0x18 0x3B) is:
00011000-00111011-MMMMMMMM-mmmmmmmm-pppppppp-TTNNNNNN-00000000-00000000
M: 8-bit major version (0-255)
m: 8-bit minor version (0-255)
p: 8-bit patch version (0-255)
T: 11 if neither an RC nor a beta
10 if an RC
01 if a beta
N: 6-bit rc/beta number (1-63)
This commit introduces the "HardenedValidations" amendment which,
if enabled, allows validators to include additional information in
their validations that can increase the robustness of consensus.
Specifically, the commit introduces a new optional field that can
be set in validation messages can be used to attest to the hash of
the latest ledger that a validator considers to be fully validated.
Additionally, the commit leverages the previously introduced "cookie"
field to improve the robustness of the network by making it possible
for servers to automatically detect accidental misconfiguration which
results in two or more validators using the same validation key.
- Add missing `#include` in `ripple/core/JobTypeInfo.h`
- Protect version string from clang-format in
`ripple/protocol/impl/BuildInfo.cpp`.
`Builds/CMake/RippledVersion.cmake` searches for this line by pattern.
