This commit combines a number of cleanups, targeting both the
code structure and the code logic. Large changes include:
- Using more strongly-typed classes for SHAMap nodes, instead of relying
on runtime-time detection of class types. This change saves 16 bytes
of memory per node.
- Improving the interface of SHAMap::addGiveItem and SHAMap::addItem to
avoid the need for passing two bool arguments.
- Documenting the "copy-on-write" semantics that SHAMap uses to
efficiently track changes in individual nodes.
- Removing unused code and simplifying several APIs.
- Improving function naming.
- Simplify and consolidate code for parsing hex input.
- Replace beast::endian::order with boost::endian::order.
- Simplify CountedObject code.
- Remove pre-C++17 workarounds in favor of C++17 based solutions.
- Improve `base_uint` and simplify its hex-parsing interface by
consolidating the `SexHex` and `SetHexExact` methods into one
API: `parseHex` which forces callers to verify the result of
the operation; as a result some public-facing API endpoints
may now return errors when passed values that were previously
accepted.
- Remove the simple fallback implementations of SHA2 and RIPEMD
introduced to reduce our dependency on OpenSSL. The code is
slow and rarely, if ever, exercised and we rely on OpenSSL
functionality for Boost.ASIO as well.
When evaluating the fitness and usefulness of an outbound peer, the code
would incorrectly calculate the amount of time that the peer spent in
a non-useful state.
This commit, if merged, corrects the calculation and makes the timeout
values configurable by server operators.
Two new options are introduced in the 'overlay' stanza of the config
file. The default values, in seconds, are:
[overlay]
max_unknown_time = 600
max_diverged_time = 300
There have been cases in the past where SFields have been defined
in such a way that they did not follow our conventions. In
particular, the string representation of an SField should match
the in-code name of the SField.
This change leverages the preprocessor to encourage SFields to
be properly constructed.
The suffixes of SField types are changed to be the same as
the suffixes of corresponding SerializedTypeIDs. This allows
The preprocessor to match types using simple name pasting.
Since the string representation of the SField is part of our
stable API, the name of sfPayChannel was changed to sfChannel.
This change allows sfChannel to follow our conventions while
making no changes to our external API.
When processing the `tx` command, we will now load both the transaction
and its metadata directly from SQLite.
Previously the `tx` RPC call was querying SQLite for the transaction
and then separately querying the key-value store for the metadata.
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.
Some RPC commands return `ledger_index` as a quoted numeric
string. This change allows the returned value to be directly
copied and used for follow-on RPC commands.
This commit fixes#3533
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.
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.
* Improve documentation
* Make the ShardArchiveHandler rather than the DatabaseShardImp perform
LastLedgerHash verification for downloaded shards
* Remove ShardArchiveHandler's singleton implementation and make it an
Application member
* Have the Application invoke ShardArchiveHandler initialization
instead of clients
* Add RecoveryHandler as a ShardArchiveHandler derived class
* Improve commenting
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.
* Make ShardArchiveHandler a singleton.
* Add state database for ShardArchiveHandler.
* Use temporary database for SSLHTTPDownloader downloads.
* Make ShardArchiveHandler a Stoppable class.
* Automatically resume interrupted downloads at server start.
* Reduce lock scope on all public functions
* Use TaskQueue to process shard finalization in separate thread
* Store shard last ledger hash and other info in backend
* Use temp SQLite DB versus control file when acquiring
* Remove boost serialization from cmake files
- Add support for all transaction types and ledger object types to gRPC
implementation of tx and account_tx.
- Create common handlers for tx and account_tx.
- Remove mutex and abort() from gRPC server. JobQueue is stopped before
gRPC server, with all coroutines executed to completion, so no need for
synchronization.
* When an unknown amendment reaches majority, log an error-level
message, and return a `warnings` array on all successful
admin-level RPC calls to `server_info` and `server_state` with
a message describing the problem, and the expected deadline.
* In addition to the `amendment_blocked` flag returned by
`server_info` and `server_state`, return a warning with a more
verbose description when the server is amendment blocked.
* Check on every flag ledger to see if the amendment(s) lose majority.
Logs again if they don't, resumes normal operations if they did.
The intention is to give operators earlier warning that their
instances are in danger of being amendment blocked, which will
hopefully motivate them to update ahead of time.
Remove the implicit conversion from int64 to XRPAmount. The motivation for this
was noticing that many calls to `to_string` with an integer parameter type were
calling the wrong `to_string` function. Since the calls were not prefixed with
`std::`, and there is no ADL to call `std::to_string`, this was converting the
int to an `XRPAmount` and calling `to_string(XRPAmount)`.
Since `to_string(XRPAmount)` did the same thing as `to_string(int)` this error
went undetected.
If merged, this commit will report additional information in the
response to the submit command; this will make it easier for developers
to accurately track the status of transaction submission.
Fixes#2851
The existing platform detection code was derived from the old Beast
library, which was, itself, derived from JUCE.
This commit removes that code and replaces it with the Boost.Predef
library which defines a consistent set of compiler, architecture,
operating system, library, and other version numbers.
For more on Boost.Predef, please see the Boost documentation. The
documentation for the current version as of this writing is at:
https://www.boost.org/doc/libs/1_71_0/doc/html/predef.html
This commit restructures the HTTP based protocol negotiation that `rippled`
executes and introduces support for negotiation of compression for peer
links which, if implemented, should result in significant bandwidth savings
for some server roles.
This commit also introduces the new `[network_id]` configuration option
that administrators can use to specify which network the server is part of
and intends to join. This makes it possible for servers from different
networks to drop the link early.
The changeset also improves the log messages generated when negotiation
of a peer link upgrade fails. In the past, no useful information would
be logged, making it more difficult for admins to troubleshoot errors.
This commit also fixes RIPD-237 and RIPD-451
* The `tx` command now supports min_ledger and max_ledger fields.
* If the requested transaction isn't found and these fields are
provided, the error response indicates whether or not every
ledger in the the provided range was searched.
This fixes#2924
