Version 2.3.0

Version 2.3.0 of rippled, the reference server implementation of the XRP Ledger protocol, is now available. This release includes 8 new amendments, including Multi-Purpose Tokens, Credentials, Clawback support for AMMs, and the ability to make offers as part of minting NFTs. Additionally, this release includes important fixes for stability, so server operators are encouraged to upgrade as soon as possible.

Action Required

If you run an XRP Ledger server, upgrade to version 2.3.0 as soon as possible to ensure service continuity.

Additionally, new amendments are now open for voting according to the XRP Ledger's amendment process, which enables protocol changes following two weeks of >80% support from trusted validators. The exact time that protocol changes take effect depends on the voting decisions of the decentralized network.

Version 2.2.3

Version 2.2.3 of rippled, the reference server implementation of the XRP Ledger protocol, is now available. This release fixes a problem that can cause full-history servers to run out of space in their SQLite databases, depending on configuration. There are no new amendments in this release.

Sign Up for Future Release Announcements

Background

The rippled server uses a SQLite database for tracking transactions, in addition to the main data store (usually NuDB) for ledger data. In servers keeping a large amount of history, this database can run out of space based on the configured number and size of database pages, even if the machine has disk space available. Based on the size of full history on Mainnet, servers with the default SQLite page size of 4096 may now run out of space if they store full history. In this case, your server may shut down with an error such as the following:

Free SQLite space for transaction db is less than 512MB. To fix this, rippled
  must be executed with the vacuum <sqlitetmpdir> parameter before restarting.
  Note that this activity can take multiple days, depending on database size.

The exact timing of when a server runs out of space can vary based on a few factors. Server operators who encountered a similar problem in 2018 and followed steps to increase the SQLite transaction database page size issue may not encounter this problem at all. The --vacuum commandline option to rippled from that time may work to free up space in the database, but requires extended downtime.

Version 2.2.3 of rippled reconfigures the maximum number of SQLite pages so that the issue does not occur.

Clio servers providing full history are not affected by this issue.

Action Required

If you run an XRP Ledger full history server, upgrading to version 2.2.3 may prevent the server from crashing when transaction.db exceeds approximately 8.7 terabytes.

Additionally, five amendments introduced in version 2.2.0 are open for voting according to the XRP Ledger's amendment process, which enables protocol changes following two weeks of >80% support from trusted validators. If you operate an XRP Ledger server older than version 2.2.0, upgrade by Sep 23, 2024 to ensure service continuity. The exact time that protocol changes take effect depends on the voting decisions of the decentralized network.

Changelog

Bug Fixes

  • Update SQLite3 max_page_count to match current defaults (#5114)

New Amendments

  • featureImmediateOfferKilled: Changes the response code of an OfferCreate transaction with the tfImmediateOrCancel flag to return tecKILLED when no funds are moved. The previous return code of tecSUCCESS was unintuitive. #4157

  • featureDisallowIncoming: Enables an account to block incoming checks, payment channels, NFToken offers, and trust lines. #4336

  • featureXRPFees: Simplifies transaction cost calculations to use XRP directly, rather than calculating indirectly in "fee units" and translating the results to XRP. Updates all instances of "fee units" in the protocol and ledger data to be drops of XRP instead. #4247

  • fixUniversalNumber: Simplifies and unifies the code for decimal floating point math. In some cases, this provides slightly better accuracy than the previous code, resulting in calculations whose least significant digits are different than when calculated with the previous code. The different results may cause other edge case differences where precise calculations are used, such as ranking of offers or processing of payments that use several different paths. #4192

  • fixNonFungibleTokensV1_2: This amendment is a combination of NFToken fixes. #4417

    • Fixes unburnable NFTokens when it has over 500 offers. #4346
    • Fixes 3 NFToken offer acceptance issues. #4380
    • Prevents brokered sales of NFTokens to owners. #4403
    • Only allows the destination to settle NFToken offers through brokerage. #4399

  • fixTrustLinesToSelf: Trust lines must be between two different accounts, but two exceptions exist because of a bug that briefly existed. This amendment removes those trust lines. 69bb2be

Changelog

New Features and Improvements

  • Improve Handshake in the peer protocol: Switched to using a cryptographically secure PRNG for the Instance Cookie. rippled now uses hex encoding for the Closed-Ledger and Previous-Ledger fields in the Handshake. Also added --newnodeid and --nodeid command line options. 5a15229

  • RPC tooBusy response now has 503 HTTP status code: Added ripplerpc 3.0, enabling RPC tooBusy responses to return relevant HTTP status codes. This is a non-breaking change that only applies to JSON-RPC when you include "ripplerpc": "3.0" in the request. #4143

  • Use the Conan package manager: Added a conanfile.py and Conan recipe for Snappy. Removed the RocksDB recipe from the repo; you can now get it from Conan Center. #4367, c2b03fe

  • Update Build Instructions: Updated the build instructions to build with the Conan package manager and restructured info for easier comprehension. #4376, #4383

  • Revise CONTRIBUTING: Updated code contribution guidelines. rippled is an open source project and contributions are very welcome. #4382

  • Update documented pathfinding configuration defaults: 417cfc2 changed the default Path Finding configuration values, but missed updating the values documented in rippled-example.cfg. Updated those defaults and added recommended values for nodes that want to support advanced pathfinding. #4409

  • Remove gRPC code previously used for the Xpring SDK: Removed gRPC code used for the Xpring SDK. The gRPC API is also enabled locally by default in rippled-example.cfg. This API is used for Reporting Mode and Clio. 28f4cc7

  • Switch from C++17 to C++20: Updated rippled to use C++20. 92d35e5

  • Support for Boost 1.80.0:: 04ef885

  • Reduce default reserves to 10/2: Updated the hard-coded default reserves to match the current settings on Mainnet. #4329

  • Improve self-signed certificate generation: Improved speed and security of TLS certificate generation on fresh startup. 0ecfc7c

Bug Fixes

  • Update command-line usage help message: Added manifest and validator_info to the rippled CLI usage statement. b88ed5a

  • Work around gdb bug by changing a template parameter: Added a workaround for a bug in gdb, where unsigned template parameters caused issues with RTTI. #4332

  • Fix clang 15 warnings: #4325

  • Catch transaction deserialization error in doLedgerGrpc: Fixed an issue in the gRPC API, so Clio can extract ledger headers and state objects from specific transactions that can't be deserialized by rippled code. #4323

  • Update dependency: gRPC: New Conan recipes broke the old version of gRPC, so the dependency was updated. #4407

  • Fix Doxygen workflow: Added options to build documentation that don't depend on the library dependencies of rippled. #4372

  • Don't try to read SLE with key 0 from the ledger: Fixed the preclaim function to check for 0 in NFTokenSellOffer and NFTokenBuyOffer before calling Ledger::read. This issue only affected debug builds. #4351

  • Update broken link to hosted Doxygen content: 5e1cb09

Code Cleanup

  • Prevent unnecessary shared_ptr copies by accepting a value in SHAMapInnerNode::setChild: #4266

  • Release TaggedCache object memory outside the lock: 3726f8b

  • Rename SHAMapStoreImp::stopping() to healthWait(): 7e9e910

Introducing XRP Ledger version 1.9.4

Version 1.9.4 of rippled, the reference implementation of the XRP Ledger protocol is now available. This release introduces an amendment that removes the ability for an NFT issuer to indicate that trust lines should be automatically created for royalty payments from secondary sales of NFTs, in response to a bug report that indicated how this functionality could be abused to mount a denial of service attack against the issuer.

Action Required

This release introduces a new amendment to the XRP Ledger protocol, fixRemoveNFTokenAutoTrustLine to mitigate a potential denial-of-service attack against NFT issuers that minted NFTs and allowed secondary trading of those NFTs to create trust lines for any asset.

This amendment is open for voting according to the XRP Ledger's amendment process, which enables protocol changes following two weeks of >80% support from trusted validators.

If you operate an XRP Ledger server, then you should upgrade to version 1.9.4 within two weeks, to ensure service continuity. The exact time that protocol changes take effect depends on the voting decisions of the decentralized network.

For more information about NFTs on the XRP Ledger, see NFT Conceptual Overview.

Install / Upgrade

On supported platforms, see the instructions on installing or updating rippled.

Changelog

Contributions

The primary change in this release is the following bug fix:

  • Introduce fixRemoveNFTokenAutoTrustLine amendment: Introduces the fixRemoveNFTokenAutoTrustLine amendment, which disables the tfTrustLine flag, which a malicious attacker could exploit to mount denial-of-service attacks against NFT issuers that specified the flag on their NFTs. (#4301)

On supported platforms, see the instructions on installing or updating rippled.

Changelog

Contributions

This release contains the following bug fixes:

  • Change by-value to by-reference to persist vote: A minor technical flaw, caused by use of a copy instead of a reference, resulted in operator-configured "yes" votes to not be properly loaded after a restart. (#4256)
  • Properly handle self-assignment of PublicKey: The PublicKey copy assignment operator mishandled the case where a PublicKey would be assigned to itself, and could result in undefined behavior.

Introducing XRP Ledger version 1.9.2

Version 1.9.2 of rippled, the reference server implementation of the XRP Ledger protocol, is now available. This release includes several fixes and improvements, including a second new fix amendment to correct a bug in Non-Fungible Tokens (NFTs) code, a new API method for order book changes, less noisy logging, and other small fixes.

Action Required

This release introduces a two new amendments to the XRP Ledger protocol. The first, fixNFTokenNegOffer, fixes a bug in code associated with the NonFungibleTokensV1 amendment, originally introduced in version 1.9.0. The second, NonFungibleTokensV1_1, is a "roll-up" amendment that enables the NonFungibleTokensV1 feature plus the two fix amendments associated with it, fixNFTokenDirV1 and fixNFTokenNegOffer.

If you want to enable NFT code on the XRP Ledger Mainnet, you can vote in favor of only the NonFungibleTokensV1_1 amendment to support enabling the feature and fixes together, without risk that the unfixed NFT code may become enabled first.

These amendments are now open for voting according to the XRP Ledger's amendment process, which enables protocol changes following two weeks of >80% support from trusted validators.

If you operate an XRP Ledger server, then you should upgrade to version 1.9.2 within two weeks, to ensure service continuity. The exact time that protocol changes take effect depends on the voting decisions of the decentralized network.

For more information about NFTs on the XRP Ledger, see NFT Conceptual Overview.

Install / Upgrade

On supported platforms, see the instructions on installing or updating rippled.

Changelog

This release contains the following features and improvements.

  • Introduce fixNFTokenNegOffer amendment. This amendment fixes a bug in the Non-Fungible Tokens (NFTs) functionality provided by the NonFungibleTokensV1 amendment (not currently enabled on Mainnet). The bug allowed users to place offers to buy tokens for negative amounts of money when using Brokered Mode. Anyone who accepted such an offer would transfer the token and pay money. This amendment explicitly disallows offers to buy or sell NFTs for negative amounts of money, and returns an appropriate error code. This also corrects the error code returned when placing offers to buy or sell NFTs for negative amounts in Direct Mode. (8266d9d)
  • Introduce NonFungibleTokensV1_1 amendment. This amendment encompasses three NFT-related amendments: the original NonFungibleTokensV1 amendment (from version 1.9.0), the fixNFTokenDirV1 amendment (from version 1.9.1), and the new fixNFTokenNegOffer amendment from this release. This amendment contains no changes other than enabling those three amendments together; this allows validators to vote in favor of only enabling the feature and fixes at the same time. (59326bb)
  • Handle invalid port numbers. If the user specifies a URL with an invalid port number, the server would silently attempt to use port 0 instead. Now it raises an error instead. This affects admin API methods and config file parameters for downloading history shards and specifying validator list sites. (#4213)
  • Reduce log noisiness. Decreased the severity of benign log messages in several places: "addPathsForType" messages during regular operation, expected errors during unit tests, and missing optional documentation components when compiling from source. (#4178, #4166, #4180)
  • Fix race condition in history shard implementation and support clang's ThreadSafetyAnalysis tool. Added build settings so that developers can use this feature of the clang compiler to analyze the code for correctness, and fix an error found by this tool, which was the source of rare crashes in unit tests. (#4188)
  • Prevent crash when rotating a database with missing data. When rotating databases, a missing entry could cause the server to crash. While there should never be a missing database entry, this change keeps the server running by aborting database rotation. (#4182)
  • Fix bitwise comparison in OfferCreate. Fixed an expression that incorrectly used a bitwise comparison for two boolean values rather than a true boolean comparison. The outcome of the two comparisons is equivalent, so this is not a transaction processing change, but the bitwise comparison relied on compilers to implicitly fix the expression. (#4183)
  • Disable cluster timer when not in a cluster. Disabled a timer that was unused on servers not running in clustered mode. The functionality of clustered servers is unchanged. (#4173)
  • Limit how often to process peer discovery messages. In the peer-to-peer network, servers periodically share IP addresses of their peers with each other to facilitate peer discovery. It is not necessary to process these types of messages too often; previously, the code tracked whether it needed to process new messages of this type but always processed them anyway. With this change, the server no longer processes peer discovery messages if it has done so recently. (#4202)
  • Improve STVector256 deserialization. Optimized the processing of this data type in protocol messages. This data type is used in several types of ledger entry that are important for bookkeeping, including directory pages that track other ledger types, amendments tracking, and the ledger hashes history. (#4204)
  • Fix and refactor spinlock code. The spinlock code, which protects the SHAMapInnerNode child lists, had a mistake that allowed the same child to be repeatedly locked under some circumstances. Fixed this bug and improved the spinlock code to make it easier to use correctly and easier to verify that the code works correctly. (#4201)
  • Improve comments and contributor documentation. Various minor documentation changes including some to reflect the fact that the source code repository is now owned by the XRP Ledger Foundation. (#4214, #4179, #4222)
  • Introduces a new API book_changes to provide information in a format that is useful for building charts that highlight DEX activity at a per-ledger level. (#4212)

Introducing XRP Ledger version 1.9.1

Version 1.9.1 of rippled, the reference server implementation of the XRP Ledger protocol, is now available. This release includes several important fixes, including a fix for a syncing issue from 1.9.0, a new fix amendment to correct a bug in the new Non-Fungible Tokens (NFTs) code, and a new amendment to allow multi-signing by up to 32 signers.

Action Required

This release introduces two new amendments to the XRP Ledger protocol. These amendments are now open for voting according to the XRP Ledger's amendment process, which enables protocol changes following two weeks of >80% support from trusted validators.

If you operate an XRP Ledger server, then you should upgrade to version 1.9.1 within two weeks, to ensure service continuity. The exact time that protocol changes take effect depends on the voting decisions of the decentralized network.

The fixNFTokenDirV1 amendment fixes a bug in code associated with the NonFungibleTokensV1 amendment, so the fixNFTokenDirV1 amendment should be enabled first. All validator operators are encouraged to configure amendment voting to oppose the NonFungibleTokensV1 amendment until after the fixNFTokenDirV1 amendment has become enabled. For more information about NFTs on the XRP Ledger, see NFT Conceptual Overview.

The ExpandedSignerList amendment extends the ledger's built-in multi-signing functionality so that each list can contain up to 32 entries instead of the current limit of 8. Additionally, this amendment allows each signer to have an arbitrary 256-bit data field associated with it. This data can be used to identify the signer or provide other metadata that is useful for organizations, smart contracts, or other purposes.

Install / Upgrade

On supported platforms, see the instructions on installing or updating rippled.

Changelog

This release contains the following features and improvements.

New Features and Amendments

  • Introduce fixNFTokenDirV1 Amendment - This amendment fixes an off-by-one error that occurred in some corner cases when determining which NFTokenPage an NFToken object belongs on. It also adjusts the constraints of NFTokenPage invariant checks, so that certain error cases fail with a suitable error code such as tecNO_SUITABLE_TOKEN_PAGE instead of failing with a tecINVARIANT_FAILED error code. (#4155)

  • Introduce ExpandedSignerList Amendment - This amendment expands the maximum signer list size to 32 entries and allows each signer to have an optional 256-bit WalletLocator field containing arbitrary data. (#4097)

  • Pause online deletion rather than canceling it if the server fails health check - The server stops performing online deletion of old ledger history if the server fails its internal health check during this time. Online deletion can now resume after the server recovers, rather than having to start over. (#4139)

Bug Fixes and Performance Improvements

  • Fix performance issues introduced in 1.9.0 - Readjusts some parameters of the ledger acquisition engine to revert some changes introduced in 1.9.0 that had adverse effects on some systems, including causing some systems to fail to sync to the network. (#4152)

  • Improve Memory Efficiency of Path Finding - Finding paths for cross-currency payments is a resource-intensive operation. While that remains true, this fix improves memory usage of pathfinding by discarding trust line results that cannot be used before those results are fully loaded or cached. (#4111)

  • Fix incorrect CMake behavior on Windows when platform is unspecified or x64 - Fixes handling of platform selection when using the cmake-gui tool to build on Windows. The generator expects Win64 but the GUI only provides x64 as an option, which raises an error. This fix only raises an error if the platform is Win32 instead, allowing the generation of solution files to succeed. (#4150)

  • Fix test failures with newer MSVC compilers on Windows - Fixes some cases where the API handler code used string pointer comparisons, which may not work correctly with some versions of the MSVC compiler. (#4149)

  • Update minimum Boost version to 1.71.0 - This release is compatible with Boost library versions 1.71.0 through 1.77.0. The build configuration and documentation have been updated to reflect this. (#4134)

  • Fix unit test failures for DatabaseDownloader - Increases a timeout in the DatabaseDownloader code and adjusts unit tests so that the code does not return spurious failures, and more data is logged if it does fail. (#4021)

  • Refactor relational database interface - Improves code comments, naming, and organization of the module that interfaces with relational databases (such as the SQLite database used for tracking transaction history). (#3965)

Releases

Version 1.9.0

This is the 1.9.0 release of rippled, the reference implementation of the XRP Ledger protocol. This release brings several features and improvements.

New and Improved Features

  • Introduce NFT support (XLS020): This release introduces support for non-fungible tokens, currently available to the developer community for broader review and testing. Developers can create applications that allow users to mint, transfer, and ultimately burn (if desired) NFTs on the XRP Ledger. You can try out the new NFT transactions using the nft-devnet. Note that some fields and error codes from earlier releases of the supporting code have been refactored for this release, shown in the Code Refactoring section, below. 70779f

  • Simplify the Job Queue: This is a refactor aimed at cleaning up and simplifying the existing job queue. Currently, all jobs are canceled at the same time and in the same way, so this commit removes the unnecessary per-job cancellation token. #3656

  • Optimize trust line caching: The existing trust line caching code was suboptimal in that it stored redundant information, pinned SLEs into memory, and required multiple memory allocations per cached object. This commit eliminates redundant data, reduces the size of cached objects and unpinning SLEs from memory, and uses value types to avoid the need for std::shared_ptr. As a result of these changes, the effective size of a cached object includes the overhead of the memory allocator, and the std::shared_ptr should be reduced by at least 64 bytes. This is significant, as there can easily be tens of millions of these objects. 4d5459

  • Incremental improvements to pathfinding memory usage: This commit aborts background pathfinding when closed or disconnected, exits the pathfinding job thread if there are no requests left, does not create the path find a job if there are no requests, and refactors to remove the circular dependency between InfoSub and PathRequest. #4111

  • Improve deterministic transaction sorting in TxQ: This commit ensures that transactions with the same fee level are sorted by TxID XORed with the parent ledger hash, the TxQ is re-sorted after every ledger, and attempts to future-proof the TxQ tie-breaking test. #4077

  • Improve stop signaling for Application: 34ca45

  • Eliminate SHAMapInnerNode lock contention: The SHAMapInnerNode class had a global mutex to protect the array of node children. Profiling suggested that around 4% of all attempts to lock the global would block. This commit removes that global mutex, and replaces it with a new per-node 16-way spinlock (implemented so as not to affect the size of an inner node object), effectively eliminating the lock contention. 1b9387

  • Improve ledger-fetching logic: When fetching ledgers, the existing code would isolate the peer that sent the most useful responses, and issue follow-up queries only to that peer. This commit increases the query aggressiveness, and changes the mechanism used to select which peers to issue follow-up queries to so as to more evenly spread the load among those peers that provided useful responses. 48803a

  • Simplify and improve order book tracking: The order book tracking code would use std::shared_ptr to track the lifetime of objects. This commit changes the logic to eliminate the overhead of std::shared_ptr by using value types, resulting in significant memory savings. b9903b

Version 1.8.5

This is the 1.8.5 release of rippled, the reference implementation of the XRP Ledger protocol. This release includes fixes and updates for stability and security, and improvements to build scripts. There are no user-facing API or protocol changes in this release.

Bug Fixes

This release contains the following bug fixes and under-the-hood improvements:

  • Correct TaggedPointer move constructor: Fixes a bug in unused code for the TaggedPointer class. The old code would fail if a caller explicitly tried to remove a child that is not actually part of the node. (227a12d)

  • Ensure protocol buffer prerequisites are present: The build scripts and packages now properly handle Protobuf packages and various packages. Prior to this change, building on Ubuntu 21.10 Impish Indri would fail unless the libprotoc-dev package was installed. (e06465f)

  • Improve handling of endpoints during peer discovery. This hardens and improves handling of incoming messages on the peer protocol. (289bc0a)

  • Run tests on updated linux distros: Test builds now run on Rocky Linux 8, Fedora 34 and 35, Ubuntu 18, 20, and 22, and Debian 9, 10, and 11. (a9ee802)

  • Avoid dereferencing empty optional in ReportingETL: Fixes a bug in Reporting Mode that could dereference an empty optional value when throwing an error. (cdc215d)

  • Correctly add GIT_COMMIT_HASH into version string: When building the server from a non-tagged release, the build files now add the commit ID in a way that follows the semantic-versioning standard, and correctly handle the case where the commit hash ID cannot be retrieved. (d23d37f)

  • Update RocksDB to version 6.27.3: Updates the version of RocksDB included in the server from 6.7.3 (which was released on 2020-03-18) to 6.27.3 (released 2021-12-10).

Version 1.8.4

This is the 1.8.4 release of rippled, the reference implementation of the XRP Ledger protocol.

This release corrects a technical flaw introduced with 1.8.3 that may result in failures if the newly-introduced 'fast loading' is enabled. The release also adjusts default parameters used to configure the pathfinding engine to reduce resource usage.

Bug Fixes

  • Adjust mutex scope in walkMapParallel: This commit corrects a technical flaw introduced with commit [7c12f0135897361398917ad2c8cda888249d42ae] that would result in undefined behavior if the server operator configured their server to use the 'fast loading' mechanism introduced with 1.8.3.

  • Adjust pathfinding configuration defaults: This commit adjusts the default configuration of the pathfinding engine, to account for the size of the XRP Ledger mainnet. Unless explicitly overriden, the changes mean that pathfinding operations will return fewer, shallower paths than previous releases.

Version 1.8.3

This is the 1.8.3 release of rippled, the reference implementation of the XRP Ledger protocol.

This release implements changes that improve the syncing performance of peers on the network, adds countermeasures to several routines involving LZ4 to defend against CVE-2021-3520, corrects a minor technical flaw that would result in the server not using a cache for nodestore operations, and adjusts tunable values to optimize disk I/O.

Summary of Issues

Recently, servers in the XRP Ledger network have been taking an increasingly long time to sync back to the network after restartiningg. This is one of several releases which will be made to improve on this issue.

Bug Fixes

  • Parallel ledger loader & I/O performance improvements: This commit makes several changes that, together, should decrease the time needed for a server to sync to the network. To make full use of this change, rippled needs to be using storage with high IOPS and operators need to explicitly enable this behavior by adding the following to their config file, under the [node_db] stanza:

    [node_db] ... fast_load=1

Note that when 'fast loading' is enabled the server will not open RPC and WebSocket interfaces until after the initial load is completed. Because of this, it may appear unresponsive or down.

  • Detect CVE-2021-3520 when decompressing using LZ4: This commit adds code to detect LZ4 payloads that may result in out-of-bounds memory accesses.

  • Provide sensible default values for nodestore cache:: The nodestore includes a built-in cache to reduce the disk I/O load but, by default, this cache was not initialized unless it was explicitly configured by the server operator. This commit introduces sensible defaults based on the server's configured node size.

  • Adjust the number of concurrent ledger data jobs: Processing a large amount of data at once can effectively bottleneck a server's I/O subsystem. This commits helps optimize I/O performance by controlling how many jobs can concurrently process ledger data.

  • Two small SHAMapSync improvements: This commit makes minor changes to optimize the way memory is used and control the amount of background I/O performed when attempting to fetch missing SHAMap nodes.

Version 1.8.2

Ripple has released version 1.8.2 of rippled, the reference server implementation of the XRP Ledger protocol. This release addresses the full transaction queues and elevated transaction fees issue observed on the XRP ledger, and also provides some optimizations and small fixes to improve the server's performance overall.

Summary of Issues

Recently, servers in the XRP Ledger network have had full transaction queues and transactions paying low fees have mostly not been able to be confirmed through the queue. After investigation, it was discovered that a large influx of transactions to the network caused it to raise the transaction costs to be proposed in the next ledger block, and defer transactions paying lower costs to later ledgers. The first part worked as designed, but deferred transactions were not being confirmed as the ledger had capacity to process them.

The root cause was that there were very many low-cost transactions that different servers in the network received in a different order due to incidental differences in timing or network topology, which caused validators to propose different sets of low-cost transactions from the queue. Since none of these transactions had support from a majority of validators, they were removed from the proposed transaction set. Normally, any transactions removed from a proposed transaction set are supposed to be retried in the next ledger, but servers attempted to put these deferred transactions into their transaction queues first, which had filled up. As a result, the deferred transactions were discarded, and the network was only able to confirm transactions that paid high costs.

Bug Fixes

  • Address elevated transaction fees: This change addresses the full queue problems in two ways. First, it puts deferred transactions directly into the open ledger, rather than transaction queue. This reverts a subset of the changes from ximinez@62127d7. A transaction that is in the open ledger but doesn't get validated should stay in the open ledger so that it can be proposed again right away. Second, it changes the order in which transactions are pulled from the transaction queue to increase the overlap in servers' initial transaction consensus proposals. Like the old rules, transactions paying higher fee levels are selected first. Unlike the old rules, transactions paying the same fee level are ordered by transaction ID / hash ascending. (Previously, transactions paying the same fee level were unsorted, resulting in each server having a different order.)

  • Add ignore_default option to account_lines API: This flag, if present, suppresses the output of incoming trust lines in the default state. This is primarily motivated by observing that users often have many unwanted incoming trust lines in a default state, which are not useful in the vast majority of cases. Being able to suppress those when doing account_lines saves bandwidth and resources. (#3980)

  • Make I/O and prefetch worker threads configurable: This commit adds the ability to specify io_workers and prefetch_workers in the config file which can be used to specify the number of threads for processing raw inbound and outbound IO and configure the number of threads for performing node store prefetching. (#3994)

  • Enforce account RPC limits by objects traversed: This changes the way the account_objects API method counts and limits the number of objects it returns. Instead of limiting results by the number of objects found, it counts by the number of objects traversed. Additionally, the default and maximum limits for non-admin connections have been decreased. This reduces the amount of work that one API call can do so that public API servers can share load more effectively. (#4032)

  • Fix a crash on shutdown: The NuDB backend class could throw an error in its destructor, resulting in a crash while the server was shutting down gracefully. This crash was harmless but resulted in false alarms and noise when tracking down other possible crashes. (#4017)

  • Improve reporting of job queue in admin server_info: The server_info command, when run with admin permissions, provides information about jobs in the server's job queue. This commit provides more descriptive names and more granular categories for many jobs that were previously all identified as "clientCommand". (#4031)

  • Improve full & compressed inner node deserialization: Remove a redundant copy operation from low-level SHAMap deserialization. (#4004)

  • Reporting mode: only forward to P2P nodes that are synced: Previously, reporting mode servers forwarded to any of their configured P2P nodes at random. This commit improves the selection so that it only chooses from P2P nodes that are fully synced with the network. (#4028)

  • Improve handling of HTTP X-Forwarded-For and Forwarded headers: Fixes the way the server handles IPv6 addresses in these HTTP headers. (#4009, #4030)

  • Other minor improvements to logging and Reporting Mode.

Version 1.8.0

Ripple has released version 1.8.0 of rippled, the reference server implementation of the XRP Ledger protocol. This release brings several features and improvements.

New and Improved Features

  • Improve History Sharding: Shards of ledger history are now assembled in a deterministic way so that any server can make a binary-identical shard for a given range of ledgers. This makes it possible to retrieve a shard from multiple sources in parallel, then verify its integrity by comparing checksums with peers' checksums for the same shard. Additionally, there's a new admin RPC command to import ledger history from the shard store, and the crawl_shards command has been expanded with more info. (#2688, #3726, #3875)
  • New CheckCashMakesTrustLine Amendment: If enabled, this amendment will change the CheckCash transaction type so that cashing a check for an issued token automatically creates a trust line to hold the token, similar to how purchasing a token in the decentralized exchange creates a trust line to hold the token. This change provides a way for issuers to send tokens to a user before that user has set up a trust line, but without forcing anyone to hold tokens they don't want. (#3823)
  • Automatically determine the node size: The server now selects an appropriate [node_size] configuration value by default if it is not explicitly specified. This parameter tunes various settings to the specs of the hardware that the server is running on, especially the amount of RAM and the number of CPU threads available in the system. Previously the server always chose the smallest value by default.
  • Improve transaction relaying logic: Previously, the server relayed every transaction to all its peers (except the one that it received the transaction from). To reduce redundant messages, the server now relays transactions to a subset of peers using a randomized algorithm. Peers can determine whether there are transactions they have not seen and can request them from a peer that has them. It is expected that this feature will further reduce the bandwidth needed to operate a server.
  • Improve the Byzantine validator detector: This expands the detection capabilities of the Byzantine validation detector. Previously, the server only monitored validators on its own UNL. Now, the server monitors for Byzantine behavior in all validations it sees.
  • Experimental tx stream with history for sidechains: Adds an experimental subscription stream for sidechain federators to track messages on the main chain in canonical order. This stream is expected to change or be replaced in future versions as work on sidechains matures.
  • Support Debian 11 Bullseye: This is the first release that is compatible with Debian Linux version 11.x, "Bullseye." The .deb packages now use absolute paths only, for compatibility with Bullseye's stricter package requirements. (#3909)
  • Improve Cache Performance: The server uses a new storage structure for several in-memory caches for greatly improved overall performance. The process of purging old data from these caches, called "sweeping", was time-consuming and blocked other important activities necessary for maintaining ledger state and participating in consensus. The new structure divides the caches into smaller partitions that can be swept in parallel.
  • Amendment default votes: Introduces variable default votes per amendment. Previously the server always voted "yes" on any new amendment unless an admin explicitly configured a voting preference for that amendment. Now the server's default vote can be "yes" or "no" in the source code. This should allow a safer, more gradual roll-out of new amendments, as new releases can be configured to understand a new amendment but not vote for it by default. (#3877)
  • More fields in the validations stream: The validations subscription stream in the API now reports additional fields that were added to validation messages by the HardenedValidations amendment. These fields make it easier to detect misconfigurations such as multiple servers sharing a validation key pair. (#3865)
  • Reporting mode supports validations and manifests streams: In the API it is now possible to connect to these streams when connected to a servers running in reporting. Previously, attempting to subscribe to these streams on a reporting server failed with the error reportingUnsupported. (#3905)

Bug Fixes

  • Clarify the safety of NetClock::time_point arithmetic: * NetClock::rep is uint32_t and can be error-prone when used with subtraction. * Fixes #3656
  • Fix out-of-bounds reserve, and some minor optimizations
  • Fix nested locks in ValidatorSite
  • Fix clang warnings about copies vs references
  • Fix reporting mode build issue
  • Fix potential deadlock in Validator sites
  • Use libsecp256k1 instead of OpenSSL for key derivation: The deterministic key derivation code was still using calls to OpenSSL. This replaces the OpenSSL-based routines with new libsecp256k1-based implementations
  • Improve NodeStore to ShardStore imports: This runs the import process in a background thread while preventing online_delete from removing ledgers pending import
  • Simplify SHAMapItem construction: The existing class offered several constructors which were mostly unnecessary. This eliminates all existing constructors and introduces a single new one, taking a Slice. The internal buffer is switched from std::vector to Buffer to save a minimum of 8 bytes (plus the buffer slack that is inherent in std::vector) per SHAMapItem instance.
  • Redesign stoppable objects: Stoppable is no longer an abstract base class, but a pattern, modeled after the well-understood std::thread. The immediate benefits are less code, less synchronization, less runtime work, and (subjectively) more readable code. The end goal is to adhere to RAII in our object design, and this is one necessary step on that path.

Version 1.7.3

This is the 1.7.3 release of rippled, the reference implementation of the XRP Ledger protocol. This release addresses an OOB memory read identified by Guido Vranken, as well as an unrelated issue identified by the Ripple C++ team that could result in incorrect use of SLEs. Additionally, this version also introduces the NegativeUNL amendment, which corresponds to the feature which was introduced with the 1.6.0 release.

Action Required

If you operate an XRP Ledger server, then you should upgrade to version 1.7.3 at your earliest convenience to mitigate the issues addressed in this hotfix. If a sufficient majority of servers on the network upgrade, the NegativeUNL amendment may gain a majority, at which point a two week activation countdown will begin. If the NegativeUNL amendment activates, servers running versions of rippled prior to 1.7.3 will become amendment blocked.

Bug Fixes

  • Improve SLE usage in check cashing: Fixes a situation which could result in the incorrect use of SLEs.
  • Address OOB in base58 decoder: Corrects a technical flaw that could allow an out-of-bounds memory read in the Base58 decoder.
  • Add NegativeUNL as a supported amendment: Introduces an amendment for the Negative UNL feature introduced in rippled 1.6.0.

Version 1.7.2

This the 1.7.2 release of rippled, the reference server implementation of the XRP Ledger protocol. This release protects against the security issue CVE-2021-3499 affecting OpenSSL, adds an amendment to fix an issue with small offers not being properly removed from order books in some cases, and includes various other minor fixes. Version 1.7.2 supersedes version 1.7.1 and adds fixes for more issues that were discovered during the release cycle.

Action Required

This release introduces a new amendment to the XRP Ledger protocol: fixRmSmallIncreasedQOffers. This amendments is now open for voting according to the XRP Ledger's amendment process, which enables protocol changes following two weeks of >80% support from trusted validators. If you operate an XRP Ledger server, then you should upgrade to version 1.7.2 within two weeks, to ensure service continuity. The exact time that protocol changes take effect depends on the voting decisions of the decentralized network. If you operate an XRP Ledger validator, please learn more about this amendment so you can make informed decisions about how your validator votes. If you take no action, your validator begins voting in favor of any new amendments as soon as it has been upgraded.

Bug Fixes

  • fixRmSmallIncreasedQOffers Amendment: This amendment fixes an issue where certain small offers can be left at the tip of an order book without being consumed or removed when appropriate and causes some payments and Offers to fail when they should have succeeded (#3827).
  • Adjust OpenSSL defaults and mitigate CVE-2021-3499: Prior to this fix, servers compiled against a vulnerable version of OpenSSL could have a crash triggered by a malicious network connection. This fix disables renegotiation support in OpenSSL so that the rippled server is not vulnerable to this bug regardless of the OpenSSL version used to compile the server. This also removes support for deprecated TLS versions 1.0 and 1.1 and ciphers that are not part of TLS 1.2 (#79e69da).
  • Support HTTP health check in reporting mode: Enables the Health Check special method when running the server in the new Reporting Mode introduced in 1.7.0 (9c8cadd).
  • Maintain compatibility for forwarded RPC responses: Fixes a case in API responses from servers in Reporting Mode, where requests that were forwarded to a P2P-mode server would have the result field nested inside another result field (8579eb0).
  • Add load_factor in reporting mode: Adds a load_factor value to the server info method response when running the server in Reporting Mode so that the response is compatible with the format returned by servers in P2P mode (the default) (430802c).
  • Properly encode metadata from tx RPC command: Fixes a problem where transaction metadata in the tx API method response would be in JSON format even when binary was requested (7311629).
  • Updates to Windows builds: When building on Windows, use vcpkg 2021 by default and add compatibility with MSVC 2019 (36fe196), (30fd458).

Version 1.7.0

Ripple has released version 1.7.0 of rippled, the reference server implementation of the XRP Ledger protocol. This release significantly improves memory usage, introduces a protocol amendment to allow out-of-order transaction execution with Tickets, and brings several other features and improvements.

New and Improved Features

  • Rework deferred node logic and async fetch behavior: This change significantly improves ledger sync and fetch times while reducing memory consumption. (https://blog.ripplex.io/how-ripples-c-team-cut-rippleds-memory-footprint-down-to-size/)
  • New Ticket feature: Tickets are a mechanism to prepare and send certain transactions outside of the normal sequence order. This version reworks and completes the implementation for Tickets after more than 6 years of development. This feature is now open for voting as the newly-introduced TicketBatch amendment, which replaces the previously-proposed Tickets amendment. The specification for this change can be found at: xrp-community/standards-drafts#16
  • Add Reporting Mode: The server can be compiled to operate in a new mode that serves API requests for validated ledger data without connecting directly to the peer-to-peer network. (The server needs a gRPC connection to another server that is on the peer-to-peer network.) Reporting Mode servers can share access to ledger data via Apache Cassandra and PostgreSQL to more efficiently serve API requests while peer-to-peer servers specialize in broadcasting and processing transactions.
  • Optimize relaying of validation and proposal messages: Servers typically receive multiple copies of any given message from directly connected peers; in particular, consensus proposal and validation messages are often relayed with extremely high redundancy. For servers with several peers, this can cause redundant work. This commit introduces experimental code that attempts to optimize the relaying of proposals and validations by allowing servers to instruct their peers to "squelch" delivery of selected proposals and validations. This change is considered experimental at this time and is disabled by default because the functioning of the consensus network depends on messages propagating with high reliability through the constantly-changing peer-to-peer network. Server operators who wish to test the optimized code can enable it in their server config file.
  • Report server domain to other servers: Server operators now have the option to configure a domain name to be associated with their servers. The value is communicated to other servers and is also reported via the server_info API. The value is meant for third-party applications and tools to group servers together. For example, a tool that visualizes the network's topology can show how many servers are operated by different stakeholders. An operator can claim any domain, so tools should use the xrp-ledger.toml file to confirm that the domain also claims ownership of the servers.
  • Improve handling of peers that aren't synced: 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 release fixes the calculation and makes the timeout values configurable by server operators. Two new options are introduced in the 'overlay' stanza of the config file.
  • Persist API-configured voting settings: Previously, the amendments that a server would vote in support of or against could be configured both via the configuration file and via the "feature" API method. Changes made in the configuration file were only loaded at server startup; changes made via the command line take effect immediately but were not persisted across restarts. Starting with this release, changes made via the API are saved to the wallet.db database file so that they persist even if the server is restarted. Amendment voting in the config file is deprecated. The first time the server starts with v1.7.0 or higher, it reads any amendment voting settings in the config file and saves the settings to the database; on later restarts the server prints a warning message and ignores the [amendments] and [veto_amendments] stanzas of the config file. Going forward, use the feature method to view and configure amendment votes. If you want to use the config file to configure amendment votes, add a line to the [rpc_startup] stanza such as the following: [rpc_startup] { "command": "feature", "feature": "FlowSortStrands", "vetoed": true }
  • Support UNLs with future effective dates: Updates the format for the recommended validator list file format, allowing publishers to pre-publish the next recommended UNL while the current one is still valid. The server is still backwards compatible with the previous format, but the new format removes some uncertainty during the transition from one list to the next. Also, starting with this release, the server locks down and reports an error if it has no valid validator list. You can clear the error by loading a validator list from a file or by configuring a different UNL and restarting; the error also goes away on its own if the server is able to obtain a trusted validator list from the network (for example, after an network outage resolves itself).
  • Improve manifest relaying: Servers now propagate change messages for validators' ephemeral public keys ("manifests") on a best-effort basis, to make manifests more available throughout the peer-to-peer network. Previously, the server would only relay manifests from validators it trusts locally, which made it difficult to detect and track validators that are not broadly trusted.
  • Implement ledger forward replay feature: The server can now sync up to the network by "playing forward" transactions from a previously saved ledger until it catches up to the network. Compared with the default behavior of fetching the latest state and working backwards, forward replay can save time and bandwidth by reconstructing previous ledgers' state data rather than downloading the pre-calculated results from the network. As an added bonus, forward replay confirms that the rest of the network followed the same transaction processing rules as the local server when processing the intervening ledgers. This feature is considered experimental this time and can be enabled with an option in the config file.
  • Make the transaction job queue limit adjustable: The server uses a job queue to manage tasks, with limits on how many jobs of a particular type can be queued. The previously hard-coded limit associated with transactions is now configurable. Server operators can increase the number of transactions their server is able to queue, which may be useful if your server has a large memory capacity or you expect an influx of transactions. (#3556)
  • Add public_key to the Validator List method response: The Validator List method can be used to request a recommended validator list from a rippled instance. The response now includes the public key of the requested list. (#3392)
  • Server operators can now configure maximum inbound and outbound peers separately: The new peers_in_max and peers_out_max config options allow server operators to independently control the maximum number of inbound and outbound peers the server allows. [70c4ecc]
  • Improvements to shard downloading: Previously the download_shard command could only load shards over HTTPS. Compressed shards can now also be downloaded over plain HTTP. The server fully checks the data for integrity and consistency, so the encryption is not strictly necessary. When initiating multiple shard downloads, the server now returns an error if there is not enough space to store all the shards currently being downloaded.
  • The manifest command is now public: The manifest API method returns public information about a given validator. The required permissions have been changed so it is now part of the public API.

Bug Fixes

  • Implement sticky DNS resolution for validator list retrieval: When attempting to load a validator list from a configured site, attempt to reuse the last IP that was successfully used if that IP is still present in the DNS response. (#3494).
  • Improve handling of RPC ledger_index argument: You can now provide the ledger_index as a numeric string. This allows you to copy and use the numeric string ledger_index value returned by certain RPC commands. Previously you could only send native JSON numbers or shortcut strings such as "validated" in the ledger_index field. (#3533)
  • Fix improper promotion of bool on return [6968da1]
  • Fix ledger sequence on copynode [ef53197]
  • Fix parsing of node public keys in manifest CLI: The previous code attempts to validate the provided node public key using a function that assumes that the encoded public key is for an account. This causes the parsing to fail. This commit fixes #3317 (#3317) by letting the caller specify the type of the public key being checked.
  • Fix idle peer timer: Fixes a bug where a function to remove idle peers was called every second instead of every 4 seconds. #3754 (#3754)
  • Add database counters: Fix bug where DatabaseRotateImp::getBackend and ::sync utilized the writable backend without a lock. ::getBackend was replaced with ::getCounters.
  • Improve online_delete configuration and DB tuning [6e9051e]
  • Improve handling of burst writes in NuDB database ( #3662 )
  • Fix excessive logging after disabling history shards. Previously if you configured the server with a shard store, then disabled it, the server output excessive warning messages about the shard limit being exceeded.
  • Fixed some issues with negotiating link compression. ( #3705 )
  • Fixed a potential thread deadlock with history sharding. ( #3683 )
  • Various fixes to typos and comments, refactoring, and build system improvements

Version 1.6.0

This release introduces several new features including changes to the XRP Ledger's consensus mechanism to make it even more robust in adverse conditions, as well as numerous bug fixes and optimizations.

New and Improved Features

  • Initial implementation of Negative UNL functionality: This change can improve the liveness of the network during periods of network instability, by allowing servers to track which validators are temporarily offline and to adjust quorum calculations to match. This change requires an amendment, but the amendment is not in the 1.6.0 release. Ripple expects to run extensive public testing for Negative UNL functionality on the Devnet in the coming weeks. If public testing satisfies all requirements across security, reliability, stability, and performance, then the amendment could be included in a version 2.0 release. [#3380]
  • Validation Hardening: This change allows servers to detect accidental misconfiguration of validators, as well as potentially Byzantine behavior by malicious validators. Servers can now log a message to notify operators if they detect a single validator issuing validations for multiple, incompatible ledger versions, or validations from multiple servers sharing a key. As part of this update, validators report the version of rippled they are using, as well as the hash of the last ledger they consider to be fully validated, in validation messages. [#3291] Amendment: Required
  • Software Upgrade Monitoring & Notification: After the HardenedValidations amendment is enabled and the validators begin reporting the versions of rippled they are running, a server can check how many of the validators on its UNL run a newer version of the software than itself. If more than 60% of a server's validators are running a newer version, the server writes a message to notify the operator to consider upgrading their software. [#3447]
  • Link Compression: Beginning with 1.6.0, server operators can enable support for compressing peer-to-peer messages. This can save bandwidth at a cost of higher CPU usage. This support is disabled by default and should prove useful for servers with a large number of peers. [#3287]
  • Unconditionalize Amendments that were enabled in 2017: This change removes legacy code which the network has not used since 2017. This change limits the ability to replay ledgers that rely on the pre-2017 behavior. [#3292]
  • New Health Check Method: Perform a simple HTTP request to get a summary of the health of the server: Healthy, Warning, or Critical. [#3365]
  • Start work on API version 2. Version 2 of the API will be part of a future release. The first breaking change will be to consolidate several closely related error messages that can occur when the server is not synced into a single "notSynced" error message. [#3269]
  • Improved shard concurrency: Improvements to the shard engine have helped reduce the lock scope on all public functions, increasing the concurrency of the code. [#3251]
  • Default Port: In the config file, the [ips_fixed] and [ips] stanzas now use the IANA-assigned port for the XRP Ledger protocol (2459) when no port is specified. The connect API method also uses the same port by default. [#2861].
  • Improve proposal and validation relaying. The peer-to-peer protocol always relays trusted proposals and validations (as part of the consensus process), but only relays untrusted proposals and validations in certain circumstances. This update adds configuration options so server operators can fine-tune how their server handles untrusted proposals and validations, and changes the default behavior to prioritize untrusted validations higher than untrusted proposals. [#3391]
  • Various Build and CI Improvements including updates to RocksDB 6.7.3 [#3356], NuDB 2.0.3 [#3437], adjusting CMake settings so that rippled can be built as a submodule [#3449], and adding Travis CI settings for Ubuntu Bionic Beaver [#3319].
  • Better documentation in the config file for online deletion and database tuning. [#3429]

Bug Fixes

  • Fix the 14 day timer to enable amendment to start at the correct quorum size [#3396]
  • Improve online delete backend lock which addresses a possibility in the online delete process where one or more backend shared pointer references may become invalid during rotation. [#3342]
  • Address an issue that can occur during the loading of validator tokens, where a deliberately malformed token could cause the server to crash during startup. [#3326]
  • Add delivered amount to GetAccountTransactionHistory. The delivered_amount field was not being populated when calling GetAccountTransactionHistory. In contrast, the delivered_amount field was being populated when calling GetTransaction. This change populates delivered_amount in the response to GetAccountTransactionHistory, and adds a unit test to make sure the results delivered by GetTransaction and GetAccountTransactionHistory match each other. [#3370]
  • Fix build issues for GCC 10 [#3393]
  • Fix historical ledger acquisition - this fixes an issue where historical ledgers were acquired only since the last online deletion interval instead of the configured value to allow deletion.[#3369]
  • Fix build issue with Docker #3416]
  • Add Shard family. The App Family utilizes a single shared Tree Node and Full Below cache for all history shards. This can create a problem when acquiring a shard that shares an account state node that was recently cached from another shard operation. The new Shard Family class solves this issue by managing separate Tree Node and Full Below caches for each shard. #3448]
  • Amendment table clean up which fixes a calculation issue with majority. #3428]
  • Add the ledger_cleaner command to rippled command line help [#3305]
  • Various typo and comments fixes.

Version 1.5.0

The rippled 1.5.0 release introduces several improvements and new features, including support for gRPC API, API versioning, UNL propagation via the peer network, new RPC methods validator_info and manifest, augmented submit method, improved tx method response, improved command line parsing, improved handshake protocol, improved package building and various other minor bug fixes and improvements.

This release also introduces two new amendments: fixQualityUpperBound and RequireFullyCanonicalSig.

Several improvements to the sharding system are currently being evaluated for inclusion into the upcoming 1.6 release of rippled. These changes are incompatible with shards generated by previous versions of the code. Additionally, an issue with the existing sharding engine can result in a server running versions 1.4 or 1.5 of the software to experience a deadlock and automatically restart when running with the sharding feature enabled. At this time, the developers recommend running with sharding disabled, pending the improvements scheduled to be introduced with 1.6. For more information on how to disable sharding, please visit https://xrpl.org/configure-history-sharding.html

New and Updated Features

  • The RequireFullyCanonicalSig amendment which changes the signature requirements for the XRP Ledger protocol so that non-fully-canonical signatures are no longer valid. This protects against transaction malleability on all transactions, instead of just transactions with the tfFullyCanonicalSig flag enabled. Without this amendment, a transaction is malleable if it uses a secp256k1 signature and does not have tfFullyCanonicalSig enabled. Most signing utilities enable tfFullyCanonicalSig by default, but there are exceptions. With this amendment, no single-signed transactions are malleable. (Multi-signed transactions may still be malleable if signers provide more signatures than are necessary.) All transactions must use the fully canonical form of the signature, regardless of the tfFullyCanonicalSig flag. Signing utilities that do not create fully canonical signatures are not supported. All of Ripple's signing utilities have been providing fully-canonical signatures exclusively since at least 2014. For more information. ec137044a
  • Native gRPC API support. Currently, this API provides a subset of the full rippled API. You can enable the gRPC API on your server with a new configuration stanza. 7d867b806
  • API Versioning which allows for future breaking change of RPC methods to co-exist with existing versions. 2aa11fa41
  • Nodes now receive and broadcast UNLs over the peer network under various conditions. 2c71802e3
  • Augmented submit method to include additional details on the status of the command. 79e9085dd
  • Improved tx method response with additional details on ledgers searched. 47501b7f9
  • New validator_info method which returns information pertaining to the current validator's keys, manifest sequence, and domain. 3578acaf0
  • New manifest method which looks up manifest information for the specified key (either master or ephemeral). 3578acaf0
  • Introduce handshake protocol for compression negotiation (compression is not implemented at this point) and other minor improvements. f6916bfd4
  • Remove various old conditionals introduced by amendments. (51ed7db00, 6e4945c56)
  • Add getRippledInfo info gathering script to rippled Linux packages. acf4b7889

Bug Fixes and Improvements

  • The fixQualityUpperBound amendment which fixes a bug in unused code for estimating the ratio of input to output of individual steps in cross-currency payments. 9d3626fec
  • tx method now properly fetches all historical tx if they are incorporated into a validated ledger under rules that applied at the time. 11cf27e00
  • Fix to how fail_hard flag is handled with the submit method - transactions that are submitted with the fail_hard flag that result in any TER code besides tesSUCCESS is neither queued nor held. cd9732b47
  • Remove unused Beast code. 172ead822
  • Lag ratchet code fix to use proper ephemeral public keys instead of the long-term master public keys.6529d3e6f

Version 1.4.0

The rippled 1.4.0 release introduces several improvements and new features, including support for deleting accounts, improved peer slot management, improved CI integration and package building and support for C++17 and Boost 1.71. Finally, this release removes the code for the SHAMapV2 amendment which failed to gain majority support and has been obsoleted by other improvements.

New and Updated Features

  • The DeletableAccounts amendment which, if enabled, will make it possible for users to delete unused or unneeded accounts, recovering the account's reserve.
  • Support for improved management of peer slots and the ability to add and removed reserved connections without requiring a restart of the server.
  • Tracking and reporting of cumulative and instantaneous peer bandwidth usage.
  • Preliminary support for post-processing historical shards after downloading to index their contents.
  • Reporting the master public key alongside the ephemeral public key in the validation stream subscriptions.
  • Reporting consensus phase changes in the server stream subscription.

Bug Fixes

  • The fixPayChanRecipientOwnerDir amendment which corrects a minor technical flaw that would cause a payment channel to not appear in the recipient's owner directory, which made it unnecessarily difficult for users to enumerate all their payment channels.
  • The fixCheckThreading amendment which corrects a minor technical flaw that caused checks to not be properly threaded against the account of the check's recipient.
  • Respect the ssl_verify configuration option in the SSLHTTPDownloader and HTTPClient classes.
  • Properly update the server_state when a server detects a disagreement between itself and the network.
  • Allow Ed25519 keys to be used with the channel_authorize command.

New and Updated Features

  • The fixMasterKeyAsRegularKey amendment which, if enabled, will correct a technical flaw that allowed setting an account's regular key to the account's master key.
  • Code that allows validators to adjust the timing of the consensus process in near-real-time to account for connection delays.
  • Support for decentralized validator domain verification by adding support for a "domain" field in manifests.

Bug Fixes

  • Improve ledger trie ancestry tracking to reduce unnecessary error messages.
  • More efficient detection of dry paths in the payment engine. Although not a transaction-breaking change, this should reduce spurious error messages in the log files.

Version 0.50.3

The rippled 0.50.3 release corrects a reported exploit that would allow a combination of trust lines and order books in a payment path to bypass the blocking effect of the NoRipple flag. Ripple recommends that all server operators immediately upgrade to version 0.50.3.

New and Updated Features

This release has no new features.

Bug Fixes

Correct a reported exploit that would allow a combination of trust lines and order books in a payment path to bypass the blocking effect of the “NoRipple” flag.

Version 0.50.2

The rippled 0.50.2 release adjusts the default TLS cipher list and corrects a flaw that would not allow an SSL handshake to properly complete if the port was configured using the wss keyword. Ripple recommends upgrading to 0.50.2 only if server operators are running rippled servers that accept client connections over TLS.

New and Updated Features

This release has no new features.

Bug Fixes

Adjust the default cipher list and correct a flaw that would not allow an SSL handshake to properly complete if the port was configured using the wss keyword (#1985)

Version 0.50.0

The rippled 0.50.0 release includes TickSize, which allows gateways to set a "tick size" for assets they issue to help promote faster price discovery and deeper liquidity, as well as reduce transaction spam and ledger churn on RCL. Ripple expects TickSize to be enabled via an Amendment called TickSize on Tuesday, 2017-02-21.

You can update to the new version on Red Hat Enterprise Linux 7 or CentOS 7 using yum. For other platforms, please compile the new version from source.

New and Updated Features

Tick Size

Currently, offers on RCL can differ by as little as one part in a quadrillion. This means that there is essentially no value to placing an offer early, as an offer placed later at a microscopically better price gets priority over it. The TickSize Amendment solves this problem by introducing a minimum tick size that a price must move for an offer to be considered to be at a better price. The tick size is controlled by the issuers of the assets involved.

This change lets issuers quantize the exchange rates of offers to use a specified number of significant digits. Gateways must enable a TickSize on their account for this feature to benefit them. A single AccountSet transaction may set a TickSize parameter. Legal values are 0 and 3-15 inclusive. Zero removes the setting. 3-15 allow that many decimal digits of precision in the pricing of offers for assets issued by this account. It will still be possible to place an offer to buy or sell any amount of an asset and the offer will still keep that amount as exactly as it does now. If an offer involves two assets that each have a tick size, the smaller number of significant figures (larger ticks) controls.

For asset pairs with XRP, the tick size imposed, if any, is the tick size of the issuer of the non-XRP asset. For asset pairs without XRP, the tick size imposed, if any, is the smaller of the two issuer's configured tick sizes.

The tick size is imposed by rounding the offer quality down to the nearest tick and recomputing the non-critical side of the offer. For a buy, the amount offered is rounded down. For a sell, the amount charged is rounded up.

The primary expected benefit of the TickSize amendment is the reduction of bots fighting over the tip of the order book, which means:

  • Quicker price discovery as outpricing someone by a microscopic amount is made impossible (currently bots can spend hours outbidding each other with no significant price movement)
  • A reduction in offer creation and cancellation spam
  • Traders can't outbid by a microscopic amount
  • More offers left on the books as priority

We also expect larger tick sizes to benefit market makers in the following ways:

  • They increase the delta between the fair market value and the trade price, ultimately reducing spreads
  • They prevent market makers from consuming each other's offers due to slight changes in perceived fair market value, which promotes liquidity
  • They promote faster price discovery by reducing the back and forths required to move the price by traders who don't want to move the price more than they need to
  • They reduce transaction spam by reducing fighting over the tip of the order book and reducing the need to change offers due to slight price changes
  • They reduce ledger churn and metadata sizes by reducing the number of indexes each order book must have
  • They allow the order book as presented to traders to better reflect the actual book since these presentations are inevitably aggregated into ticks

Hardened TLS configuration

This release updates the default TLS configuration for rippled. The new release supports only 2048-bit DH parameters and defines a new default set of modern ciphers to use, removing support for ciphers and hash functions that are no longer considered secure.

Server administrators who wish to have different settings can configure custom global and per-port cipher suites in the configuration file using the ssl_ciphers directive.

Upcoming Features

We expect the previously announced Suspended Payments feature, which introduces new transaction types to the Ripple protocol that will permit users to cryptographically escrow XRP on RCL, to be enabled via the SusPay Amendment on Tuesday, 2017-02-21.

Also, we expect support for crypto-conditions, which are signature-like structures that can be used with suspended payments to support ILP integration, to be included in the next rippled release scheduled for March.

Lastly, we do not have an update on the previously announced changes to the hash tree structure that rippled uses to represent a ledger, called SHAMapV2. At the time of activation, this amendment will require brief scheduled allowable unavailability while the changes to the hash tree structure are computed by the network. We will keep the community updated as we progress towards this date (TBA).

Version 0.40.1

The rippled 0.40.1 release increases SQLite database limits in all rippled servers. Ripple recommends upgrading to 0.40.1 only if server operators are running rippled servers with full-history of the ledger. There are no new or updated features in the 0.40.1 release.

You can update to the new version on Red Hat Enterprise Linux 7 or CentOS 7 using yum. For other platforms, please compile the new version from source.

New and Updated Features

This release has no new features.

Bug Fixes

Increase SQLite database limits to prevent full-history servers from crashing when restarting. (#1961)

Version 0.40.0

The rippled 0.40.0 release includes Suspended Payments, a new transaction type on the Ripple network that functions similar to an escrow service, which permits users cryptographically escrow XRP on RCL with an expiration date. Ripple expects Suspended Payments to be enabled via an Amendment named SusPay on Tuesday, 2017-01-17.

You can update to the new version on Red Hat Enterprise Linux 7 or CentOS 7 using yum. For other platforms, please compile the new version from source.

New and Updated Features

Previously, Ripple announced the introduction of Payment Channels during the release of rippled version 0.33.0, which permit scalable, off-ledger checkpoints of high volume, low value payments flowing in a single direction. This was the first step in a multi-phase effort to make RCL more scalable and to support Interledger Protocol (ILP). Ripple expects Payment Channels to be enabled via an Amendment called PayChan on a future date to be determined.

In the second phase towards making RCL more scalable and compatible with ILP, Ripple is introducing Suspended Payments, a new transaction type on the Ripple network that functions similar to an escrow service, which permits users to cryptographically escrow XRP on RCL with an expiration date. Ripple expects Suspended Payments to be enabled via an Amendment named SusPay on Tuesday, 2017-01-17.

A Suspended Payment can be created, which deducts the funds from the sending account. It can then be either fulfilled or canceled. It can only be fulfilled if the fulfillment transaction makes it into a ledger with a CloseTime lower than the expiry date of the transaction. It can be canceled with a transaction that makes it into a ledger with a CloseTime greater than the expiry date of the transaction.

In the third phase towards making RCL more scalable and compatible with ILP, Ripple plans to introduce additional library support for crypto-conditions, which are distributable event descriptions written in a standard format that describe how to recognize a fulfillment message without saying exactly what the fulfillment is. Fulfillments are cryptographically verifiable messages that prove an event occurred. If you transmit a fulfillment, then everyone who has the condition can agree that the condition has been met. Fulfillment requires the submission of a signature that matches the condition (message hash and public key). This format supports multiple algorithms, including different hash functions and cryptographic signing schemes. Crypto-conditions can be nested in multiple levels, with each level possibly having multiple signatures.

Lastly, we do not have an update on the previously announced changes to the hash tree structure that rippled uses to represent a ledger, called SHAMapV2. This will require brief scheduled allowable downtime while the changes to the hash tree structure are propagated by the network. We will keep the community updated as we progress towards this date (TBA).

Version 0.33.0

The rippled 0.33.0 release includes an improved version of the payment code, which we expect to be activated via Amendment on Wednesday, 2016-10-20 with the name Flow. We are also introducing XRP Payment Channels, a new structure in the ledger designed to support Interledger Protocol trust lines as balances get substantial, which we expect to be activated via Amendment on a future date (TBA) with the name PayChan. Lastly, we will be introducing changes to the hash tree structure that rippled uses to represent a ledger, which we expect to be available via Amendment on a future date (TBA) with the name SHAMapV2.

You can update to the new version on Red Hat Enterprise Linux 7 or CentOS 7 using yum. For other platforms, please compile the new version from source.

** New and Updated Features **

A fixed version of the new payment processing engine, which we initially announced on Friday, 2016-07-29, is expected to be available via Amendment on Wednesday, 2016-10-20 with the name Flow. The new payments code adds no new features, but improves efficiency and robustness in payment handling.

The Flow code may occasionally produce slightly different results than the old payment processing engine due to the effects of floating point rounding.

We will be introducing changes to the hash tree structure that rippled uses to represent a ledger, which we expect to be activated via Amendment on a future date (TBA) with the name SHAMapV2. The new structure is more compact and efficient than the previous version. This affects how ledger hashes are calculated, but has no other user-facing consequences. The activation of the SHAMapV2 amendment will require brief scheduled allowable downtime, while the changes to the hash tree structure are propagated by the network. We will keep the community updated as we progress towards this date (TBA).

In an effort to make RCL more scalable and to support Interledger Protocol (ILP) trust lines as balances get more substantial, we’re introducing XRP Payment Channels, a new structure in the ledger, which we expect to be available via Amendment on a future date (TBA) with the name PayChan.

XRP Payment Channels permit scalable, intermittent, off-ledger settlement of ILP trust lines for high volume payments flowing in a single direction. For bidirectional channels, an XRP Payment Channel can be used in each direction. The recipient can claim any unpaid balance at any time. The owner can top off the channel as needed. The owner must wait out a delay to close the channel to give the recipient a chance to supply any claims. The total amount paid increases monotonically as newer claims are issued.

The initial concept behind payment channels was discussed as early as 2011 and the first implementation was done by Mike Hearn in bitcoinj. Recent work being done by Lightning Network has showcased examples of the many use cases for payment channels. The introduction of XRP Payment Channels allows for a more efficient integration between RCL and ILP to further support enterprise use cases for high volume payments.

Version 0.32.1

The rippled 0.32.1 release includes an improved version of the payment code, which we expect to be available via Amendment on Wednesday, 2016-08-24 with the name FlowV2, and a completely new implementation of the WebSocket protocol for serving clients.

You can update to the new version on Red Hat Enterprise Linux 7 or CentOS 7 using yum. For other platforms, please compile the new version from source.

New and Updated Features

An improved version of the payment processing engine, which we expect to be available via Amendment on Wednesday, 2016-08-24 with the name “FlowV2”. The new payments code adds no new features, but improves efficiency and robustness in payment handling.

The FlowV2 code may occasionally produce slightly different results than the old payment processing engine due to the effects of floating point rounding. Once FlowV2 is enabled on the network then old servers without the FlowV2 amendment will lose sync more frequently because of these differences.

Beast WebSocket

A completely new implementation of the WebSocket protocol for serving clients is available as a configurable option for rippled administrators. To enable this new implementation, change the “protocol” field in rippled.cfg from “ws” to “ws2” (or from “wss” to “wss2” for Secure WebSockets), as illustrated in this example:

[port_ws_public]
port = 5006
ip = 0.0.0.0
protocol = wss2

The new implementation paves the way for increased reliability and future performance when submitting commands over WebSocket. The behavior and syntax of commands should be identical to the previous implementation. Please report any issues to [email protected]. A future version of rippled will remove the old WebSocket implementation, and use only the new one.

Bug fixes

Fix a non-exploitable, intermittent crash in some client pathfinding requests (RIPD-1219)

Fix a non-exploitable crash caused by a race condition in the HTTP server. (RIPD-1251)

Fix bug that could cause a previously fee queued transaction to not be relayed after being in the open ledger for an extended time without being included in a validated ledger. Fix bug that would allow an account to have more than the allowed limit of transactions in the fee queue. Fix bug that could crash debug builds in rare cases when replacing a dropped transaction. (RIPD-1200)

Remove incompatible OS X switches in Test.py (RIPD-1250)

Autofilling a transaction fee (sign / submit) with the experimental x-queue-okay parameter will use the user’s maximum fee if the open ledger fee is higher, improving queue position, and giving the tx more chance to succeed. (RIPD-1194)

Version 0.32.0

The rippled 0.32.0 release improves transaction queue which now supports batching and can hold up to 10 transactions per account, allowing users to queue multiple transactions for processing when the network load is high. Additionally, the server_info and server_state commands now include information on transaction cost multipliers and the fee command is available to unprivileged users. We advise rippled operators to upgrade immediately.

You can update to the new version on Red Hat Enterprise Linux 7 or CentOS 7 using yum. For other platforms, please compile the new version from source.

New and Updated Features

  • Allow multiple transactions per account in transaction queue (RIPD-1048). This also introduces a new transaction engine code, telCAN_NOT_QUEUE.
  • Charge pathfinding consumers per source currency (RIPD-1019): The IP address used to perform pathfinding operations is now charged an additional resource increment for each source currency in the path set.
  • New implementation of payment processing engine. This implementation is not yet enabled by default.
  • Include amendments in validations subscription
  • Add C++17 compatibility
  • New WebSocket server implementation with Beast.WebSocket library. The new library offers a stable, high-performance websocket server implementation. To take advantage of this implementation, change websocket protocol under rippled.cfg from wss and ws to wss2 and ws2 under [port_wss_admin] and [port_ws_public] stanzas:
     [port_wss_admin]
     port = 51237
     ip = 127.0.0.1
     admin = 127.0.0.1
     protocol = wss2

     [port_ws_public]
     port = 51233
     ip = 0.0.0.0
     protocol = wss2, ws2
  • The fee command is now public (RIPD-1113)
  • The fee command checks open ledger rules (RIPD-1183)
  • Log when number of available file descriptors is insufficient (RIPD-1125)
  • Publish all validation fields for signature verification
  • Get quorum and trusted master validator keys from validators.txt
  • Standalone mode uses temp DB files by default (RIPD-1129): If a [database_path] is configured, it will always be used, and tables will be upgraded on startup.
  • Include config manifest in server_info admin response (RIPD-1172)

Bug fixes

  • Fix history acquire check (RIPD-1112)
  • Correctly handle connections that fail security checks (RIPD-1114)
  • Fix secured Websocket closing
  • Reject invalid MessageKey in SetAccount handler (RIPD-308, RIPD-990)
  • Fix advisory delete effect on history acquisition (RIPD-1112)
  • Improve websocket send performance (RIPD-1158)
  • Fix XRP bridge payment bug (RIPD-1141)
  • Improve error reporting for wallet_propose command. Also include a warning if the key used may be an insecure, low-entropy key. (RIPD-1110)

Deprecated features

  • Remove obsolete sendGetPeers support (RIPD-164)
  • Remove obsolete internal command (RIPD-888)

Version 0.31.2

The rippled 0.31.2 release corrects issues with the fee escalation algorithm. We advise rippled operators to upgrade immediately.

You can update to the new version on Red Hat Enterprise Linux 7 or CentOS 7 using yum. For other platforms, please compile the new version from source.

New and Updated Features

This release has no new features.

Bug Fixes

  • A defect in the fee escalation algorithm that caused network fees to escalate more rapidly than intended has been corrected. (RIPD-1177)
  • The minimum local fee advertised by validators will no longer be adjusted upwards.

Version 0.31.1

The rippled 0.31.1 release contains one important bug fix. We advise rippled operators to upgrade immediately.

You can update to the new version on Red Hat Enterprise Linux 7 or CentOS 7 using yum. For other platforms, please compile the new version from source.

New and Updated Features

     Set version to 0.31.0

Warnings

Please expect a one-time delay when starting 0.31.0 while certain database indices are being built or rebuilt. The delay can be up to five minutes, during which CPU will spike and the server will appear unresponsive (no response to RPC, etc.).

Additionally, rippled 0.31.0 now checks at start-up time that it has sufficient open file descriptors available, and shuts down with an error message if it does not. Previous versions of rippled could run out of file descriptors unexpectedly during operation. If you get a file-descriptor error message, increase the number of file descriptors available to rippled (for example, editing /etc/security/limits.conf) and restart.

Version 0.30.0

rippled 0.30.0 has been released. The commit can be found on GitHub at: https://github.com/ripple/rippled/tree/0.30.0

Prior to building, please confirm you have the correct source tree with the git log command. The first log entry should be the change setting the version:

 commit a8859b495b552fe1eb140771f0f2cb32d11d2ac2
 Author: Vinnie Falco <[email protected]>
 Date:   Wed Oct 21 18:26:02 2015 -0700

    Set version to 0.30.0

This release incorporates a number of important features, bugfixes and functional improvements. Please refer to the Git commit history for more detailed information.

Release Overview

As part of Ripple Labs’ ongoing commitment toward protocol security, the rippled team would like to release rippled 0.30.0.

Toolchain support

The minimum supported version of GCC used to compile rippled is v4.8. Please follow these instructions if you have not upgraded already.

While it may be possible to compile rippled on (virtual) machines with 4GB of RAM, we recommend compiling on (virtual) machines with 8GB of RAM or more. If your build machine has more than one CPU (grep '^processor' /proc/cpuinfo | wc -l), you can use them to assist in the build process by compiling with the command scons -j[number of CPUs - 1].

New Features

  • Honor markers in ledger_data requests (RIPD-1010).
  • New Amendment - TrustSetAuth (Not currently enabled) Create zero balance trust lines with auth flag (RIPD-1003): this allows a TrustSet transaction to create a trust line if the only thing being changed is setting the tfSetfAuth flag.
  • Randomize the initial transaction execution order for closed ledgers based on the hash of the consensus set (RIPD-961). Activates on October 27, 2015 at 11:00 AM PCT.
  • Differentiate path_find response (RIPD-1013).
  • Convert all of an asset (RIPD-655).

Improvements

  • SHAMap improvements.

  • Upgrade SQLite from 3.8.8.2 to 3.8.11.1.

  • Limit the number of offers that can be consumed during crossing (RIPD-1026).

  • Remove unfunded offers on tecOVERSIZE (RIPD-1026).

  • Improve transport security (RIPD-1029): to take full advantage of the improved transport security, servers with a single, static public IP address should add it to their configuration file, as follows:

    [overlay] public_ip=<ip_address>

Development-Related Updates

  • Transitional support for gcc 5.2: to enable support define the environmental variable RIPPLED_OLD_GCC_ABI=1
  • Transitional support for C++ 14: to enable support define the environment variable RIPPLED_USE_CPP_14=1
  • Visual Studio 2015 support
  • Updates to integration tests
  • Add uptime to crawl data (RIPD-997)

Important rippled.cfg update

With rippled version 0.28, the rippled.cfg file must be changed according to these instructions:

  • Change any entries that say

admin = allow to admin =

  • For most installations, 127.0.0.1 will preserve current behavior. 0.0.0.0 may be specified to indicate "any IP" but cannot be combined with other IP addresses. Use of 0.0.0.0 may introduce severe security risks and is not recommended. See docs/rippled-example.cfg for more information.

More Strict Requirements on MemoType

The requirements on the contents of the MemoType field, if present, are more strict than the previous version. Transactions that can successfully be submitted to 0.27.4 and earlier may fail in 0.28.0. For details, please refer to updated memo documentation for details. Partners should check their implementation to make sure that their MemoType follows the new rules.

New Features

New Features

  • RocksDB to NuDB import tool (RIPD-781, RIPD-785): custom tool specifically designed for very fast import of RocksDB nodestore databases into NuDB

Bug Fixes

  • Fix streambuf bug

Improvements

  • Update RocksDB backend settings
  • NuDB improvements:
    • Limit size of mempool (RIPD-787)
    • Performance improvements (RIPD-793, RIPD-796): changes in Nudb to improve speed, reduce database size, and enhance correctness. The most significant change is to store hashes rather than entire keys in the key file. The output of the hash function is reduced to 48 bits, and stored directly in buckets.

Experimental

  • Add /crawl cgi request feature to peer protocol (RIPD-729): adds support for a cgi /crawl request, issued over HTTPS to the configured peer protocol port. The response to the request is a JSON object containing the node public key, type, and IP address of each directly connected neighbor. The IP address is suppressed unless the neighbor has requested its address to be revealed by adding "Crawl: public" to its HTTP headers. This field is currently set by the peer_private option in the rippled.cfg file.

Version 0.27.0

rippled 0.27.0 has been released. The commit can be found on GitHub at: https://github.com/ripple/rippled/tree/0.27.0

Prior to building, please confirm you have the correct source tree with the git log command. The first log entry should be the change setting the version:

 commit c6c8e5d70c6fbde02cd946135a061aa77744396f
 Author: Vinnie Falco <[email protected]>
 Date:   Mon Jan 26 10:56:11 2015 -0800

     Set version to 0.27.0

This release incorporates a number of important bugfixes and functional improvements. Please refer to the Git commit history for more detailed information.

Release Overview

The rippled team is proud to release rippled 0.27.0. This new version includes many exciting features that will appeal to our users. The team continues to work on stability, scalability, and performance.

The first feature is Online Delete. This feature allows rippled to maintain it’s database of previous ledgers within a fixed amount of disk space. It does this while allowing rippled to stay online and maintain an administrator specify minimum number of ledgers. This means administrators with limited disk space will no longer need to manage disk space by periodically manually removing the database. Also, with the previously existing backend databases performance would gradually degrade as the database grew in size. In particular, rippled would perform poorly whenever the backend database performed ever growing compaction operations. By limiting rippled to less history, compaction is less resource intensive and systems with less disk performance can now run rippled.

Additionally, we are very excited to include Universal Port. This feature allows rippled's listening port to handshake in multiple protocols. For example, a single listening port can be configured to receive incoming peer connections, incoming RPC commands over HTTP, and incoming RPC commands over HTTPS at the same time. Or, a single port can receive both Websockets and Secure Websockets clients at the same.

Finally, a new, experimental backend database, NuDB, has been added. This database was developed by Ripple Labs to take advantage of rippled’s specific data usage profile and performs much better than previous databases. Significantly, this database does not degrade in performance as the database grows. Very excitingly, this database works on OS X and Windows. This allows rippled to use these platforms for the first time.

Toolchain support

The minimum supported version of GCC used to compile rippled is v4.8. Please follow these instructions if you have not upgraded already.

While it may be possible to compile rippled on (virtual) machines with 4GB of RAM, we recommend compiling on (virtual) machines with 8GB of RAM or more. If your build machine has more than one CPU (`grep '^processor' /proc/cpuinfo | wc -l`), you can use them to assist in the build process by compiling with the command scons -j[number of CPUs - 1].

The minimum supported version of Boost is v1.57.0. You must upgrade to this release or later to successfully compile this release of rippled. Please follow these instructions if you have not upgraded already.

Important rippled.cfg Update

The format of the configuration file has changed. If upgrading from a previous version of rippled, please see the migration instructions below.

New Features

  • SHAMapStore Online Delete (RIPD-415): 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. See doc/rippled-example.cfg for configuration setup.
  • Universal Port. See necessary config changes below.
  • Config "ledger_history_index" option (RIPD-559)

Bug Fixes

  • Fix pathfinding with multiple issuers for one currency (RIPD-618)
  • Fix account_lines, account_offers and book_offers result (RIPD-682)
  • Fix pathfinding bugs (RIPD-735)
  • Fix RPC subscribe with multiple books (RIPD-77)
  • Fix account_tx API

Improvements

  • Improve the human-readable description of the tesSUCCESS code
  • Add 'delivered_amount' to Transaction JSON (RIPD-643): The synthetic field 'delivered_amount' can be used to determine the exact amount delivered by a Payment without having to check the DeliveredAmount field, if present, or the Amount field otherwise.

Development-Related Updates

  • HTTP Handshaking for Peers on Universal Port (RIPD-446)
  • Use asio signal handling in Application (RIPD-140)
  • Build dependency on Boost 1.57.0
  • Support a "no_server" flag in test config
  • API for improved Unit Testing (RIPD-432)
  • Option to specify rippled path on command line (--rippled=<absolute or relative path>)

Experimental

  • NuDB backend option: high performance key/value database optimized for rippled (set “type=nudb” in .cfg)

Migration Instructions

With rippled version 0.27.0, the rippled.cfg file must be changed according to these instructions:

  • Add new stanza - [server]. This section will contain a list of port names and key/value pairs. A port name must start with a letter and contain only letters and numbers. The name is not case-sensitive. For each name in this list, rippled will look for a configuration file section with the same name and use it to create a listening port. To simplify migration, you can use port names from your previous version of rippled.cfg (see Section 1. Server for detailed explanation in doc/rippled-example.cfg). For example:

     [server]
 rpc_port
 peer_port
 websocket_port
 ssl_key = <set value to your current [rpc_ssl_key] or [websocket_ssl_key] setting>
 ssl_cert = <set value to your current [rpc_ssl_cert] or [websocket_ssl_cert] setting>
 ssl_chain = <set value to your current [rpc_ssl_chain] or [websocket_ssl_chain] setting>

  • For each port name in [server] stanza, add separate stanzas. For example:

     [rpc_port]
 port = <set value to your current [rpc_port] setting, usually 5005>
 ip = <set value to your current [rpc_ip] setting, usually 127.0.0.1>
 admin = allow
 protocol = https

 [peer_port]
 port = <set value to your current [peer_port], usually 51235>
 ip = <set value to your current [peer_ip], usually 0.0.0.0>
 protocol = peer

 [websocket_port]
 port = <your current [websocket_port], usually 6006>
 ip = <your current [websocket_ip], usually 127.0.0.1>
 admin = allow
 protocol = wss

  • Remove current [rpc_port], [rpc_ip], [rpc_allow_remote], [rpc_ssl_key], [rpc_ssl_cert], and [rpc_ssl_chain], [peer_port], [peer_ip], [websocket_port], [websocket_ip] settings from rippled.cfg

  • If you allow untrusted websocket connections to your rippled, add [websocket_public_port] stanza under [server] section and replace websocket public settings with [websocket_public_port] section:

     [websocket_public_port]
 port = <your current [websocket_public_port], usually 5005>
 ip = <your current [websocket_public_ip], usually 127.0.0.1>
 protocol = ws ← make sure this is ws, not wss`

  • Remove [websocket_public_port], [websocket_public_ip], [websocket_ssl_key], [websocket_ssl_cert], [websocket_ssl_chain] settings from rippled.cfg

  • Disable [ssl_verify] section by setting it to 0

  • Migrate the remaining configurations without changes. To enable online delete feature, check Section 6. Database in doc/rippled-example.cfg

Integration Notes

With this release, integrators should deprecate the "DeliveredAmount" field in favor of "delivered_amount."

For Transactions That Occurred Before January 20, 2014:

  • If amount actually delivered is different than the transactions “Amount” field
    • "delivered_amount" will show as unavailable indicating a developer should use caution when processing this payment.
    • Example: A partial payment transaction (tfPartialPayment).
  • Otherwise
    • "delivered_amount" will show the correct destination balance change.

For Transactions That Occur After January 20, 2014:

  • If amount actually delivered is different than the transactions “Amount” field
    • A "delivered_amount" field will determine the destination amount change
    • Example: A partial payment transaction (tfPartialPayment).
  • Otherwise
    • "delivered_amount" will show the correct destination balance change.

RocksDB back end

RocksDB is based on LevelDB with improvements from Facebook and the community. Preliminary tests show that it stalls less often than HyperLevelDB for our use cases.

If you are switching over from an existing back end, you have two options. You can remove your old database and let rippled recreate it as it re-syncs, or you can import your old database into the new one.

To remove your old database, make sure the server is shut down (`rippled stop`). Remove the db/ledger.db and db/transaction.db files. Remove all the files in your back end store directory (db/hashnode by default). Then change your configuration file to use the RocksDB back end and restart.

To import your old database, start by shutting the server down. Then modify the configuration file by renaming your [node_db] stanza to [import_db]. Create a new [node_db] stanza and specify a RocksDB back end with a different directory. Start the server with the command rippled --import. When the import finishes gracefully stop the server (`rippled stop`). Please wait for rippled to stop on its own because it can take several minutes for it to shut down after an import. Remove the old database, put the new database into place, remove the [import_db] section, change the [node_db] section to refer to the final location, and restart the server.

The recommended RocksDB configuration is:

 [node_db]
 type=RocksDB
 path=db/hashnode
 open_files=1200
 filter_bits=12
 cache_mb=128
 file_size_mb=8
 file_size_mult=2

Configuring your Node DB

You need to configure the NodeBackEnd that you want the server to use. See above for an example RocksDB configuration.

  • Note: HyperLevelDB and RocksDB are not available on Windows platform.

Version 0.20.1

rippled version 0.20.1 has been released. This release is currently the tip of the develop branch and the tag is 0.20.1.

This is a critical release. All partners should update immediately.

Prior to building, please confirm you have the correct source tree with the git log command. The first log entry should be the change setting the version:

commit 95a573b755219d7e1e078d53b8e11a8f0d7cade1
Author: Vinnie Falco <[email protected]>
Date:   Wed Jan 8 17:08:27 2014 -0800

   Set version to 0.20.1

Major Partner Issues Fixed

  • rippled will crash randomly.
    • Entries in the three parts of the order book are missing or do not match. In such a case, rippled will crash.
  • Server loses sync randomly.
    • This is due to rippled restarting after it crashes. That the server restarted is not obvious and appears to be something else.
  • Server goes 'offline' randomly.
    • This is due to rippled restarting after it crashes. That the server restarted is not obvious and appears to be something else.
  • complete_ledgers part of server_info output says "None".
    • This is due to rippled restarting and reconstructing the ledger after it crashes.
    • If the node back end is corrupted or has been moved without being renamed in rippled.cfg, this can cause rippled to crash and restart.

Toolchain support

Starting with this release, the minimum supported version of GCC used to compile rippled is v4.8.

Significant Changes

  • Don't log StatsD messages to the console by default.
  • Fixed missing jtACCEPT job limit.
  • Removed dead code to clean up the codebase.

    • Make each path request track whether it needs updating.
    • Improve new request handling, reverse order for processing requests.
    • Break to handle new requests immediately.
    • Make mPathFindThread an integer rather than a bool. Allow two threads.
    • Suspend processing requests if server is backed up.
    • Multiple performance improvements and enhancements.
    • Fixed locking.
  • Refactored codebase to make it C++11 compliant.
  • Multiple fixes to ledger acquisition, cleanup, and logging.
  • Made multiple improvements to WebSockets server.
  • Added Debian-style initscript (doc/rippled.init).
  • Updated default config file (doc/rippled-example.cfg) to reflect best practices.
  • Made changes to SHAMapTreeNode and visitLeavesInternal to conserve memory.
  • Implemented new fee schedule:
    • Transaction fee: 10 drops
    • Base reserve: 20 XRP
    • Incremental reserve: 5 XRP
  • Fixed bug #211 (getTxsAccountB in NetworkOPs).
  • Fixed a store/fetch race condition in ther node back end.
  • Fixed multiple comparison operations.
  • Removed Sophia and Lightning databases.

Notice

If you are upgrading from version 0.12 or earlier of rippled, these next sections apply to you because the format of the rippled.cfg file changed around that time. If you have upgraded since that time and you have applied the configuration file fixes, you can safely ignore them.

    Set version to v0.12.0

Major Partner Issues Fixed

  • Server Showing "Offline"

This issue was caused by LevelDB periodically compacting its internal data structure. While compacting, rippled's processing would stall causing the node to lose sync with the rest of the network. This issue was solved by switching from LevelDB to HyperLevelDB. rippled operators will need to change their ripple.cfg file. See below for configuration details.

  • Premature Validation of Transactions

On rare occasions, a transaction would show as locally validated before the full network consensus was confirmed. This issue was resolved by changing the way transactions are saved.

  • Missing Ledgers

Occasionally, some rippled servers would fail to fetch all ledgers. This left gaps in the local history and caused some API calls to report incomplete results. The ledger fetch code was rewritten to both prevent this and to repair any existing gaps.

Significant Changes

  • The way transactions are saved has been changed. This fixes a number of ways transactions can incorrectly be reported as fully-validated.
  • doTransactionEntry now works against open ledgers.
  • doLedgerEntry now supports a binary option.
  • A bug in getBookPage that caused it to skip offers is fixed.
  • getNodeFat now returns deeper chains, reducing ledger acquire latency.
  • Catching up if the (published ledger stream falls behind the network) is now more aggressive.
  • I/O stalls are drastically reduced by using the HyperLevelDB node back end.
  • Persistent ledger gaps should no longer occur.
  • Clusters now exchange load information.

RC3 fixed compilation under OSX.

RC4 includes performance improvements in countAccountTx and numerous small fixes to ledger acquisition.

RC5 changed the peer low water mark from 4 to 10 to acquire more server connections.

RC6 fixed some possible load issues with the network state timer and cluster reporting timers.

Issues

Fetching of historical ledgers is slower in this build than in previous builds. This is being investigated.
