* Price Oracle (XLS-47d): (XRPLF#4789) (XRPLF#4789) Implement native support for Price Oracles. A Price Oracle is used to bring real-world data, such as market prices, onto the blockchain, enabling dApps to access and utilize information that resides outside the blockchain. Add Price Oracle functionality: - OracleSet: create or update the Oracle object - OracleDelete: delete the Oracle object To support this functionality add: - New RPC method, `get_aggregate_price`, to calculate aggregate price for a token pair of the specified oracles - `ltOracle` object The `ltOracle` object maintains: - Oracle Owner's account - Oracle's metadata - Up to ten token pairs with the scaled price - The last update time the token pairs were updated Add Oracle unit-tests * fix compile error on gcc 13: (XRPLF#4932) The compilation fails due to an issue in the initializer list of an optional argument, which holds a vector of pairs. The code compiles correctly on earlier gcc versions, but fails on gcc 13. * Set version to 2.2.0-b1 * Remove default ctors from SecretKey and PublicKey: (XRPLF#4607) * It is now an invariant that all constructed Public Keys are valid, non-empty and contain 33 bytes of data. * Additionally, the memory footprint of the PublicKey class is reduced. The size_ data member is declared as static. * Distinguish and identify the PublisherList retrieved from the local config file, versus the ones obtained from other validators. * Fixes XRPLF#2942 * Fast base58 codec: (XRPLF#4327) This algorithm is about an order of magnitude faster than the existing algorithm (about 10x faster for encoding and about 15x faster for decoding - including the double hash for the checksum). The algorithms use gcc's int128 (fast MS version will have to wait, in the meantime MS falls back to the slow code). * feat: add user version of `feature` RPC (XRPLF#4781) * uses same formatting as admin RPC * hides potentially sensitive data * build: add STCurrency.h to xrpl_core to fix clio build (XRPLF#4939) * Embed patched recipe for RocksDB 6.29.5 (XRPLF#4947) * fix: order book update variable swap: (XRPLF#4890) This is likely the result of a typo when the code was simplified. * Fix workflows (XRPLF#4948) The problem was `CONAN_USERNAME` environment variable, which Conan 1.x uses as the default user in package references. * Upgrade to xxhash 0.8.2 as a Conan requirement, enable SIMD hashing (XRPLF#4893) We are currently using old version 0.6.2 of `xxhash`, as a verbatim copy and paste of its header file `xxhash.h`. Switch to the more recent version 0.8.2. Since this version is in Conan Center (and properly protects its ABI by keeping the state object incomplete), add it as a Conan requirement. Switch to the SIMD instructions (in the new `XXH3` family) supported by the new version. * Update remaining actions (XRPLF#4949) Downgrade {upload,download}-artifact action to v3 because of unreliability with v4. * Install more public headers (XRPLF#4940) Fixes some mistakes in XRPLF#4885 * test: Env unit test RPC errors return a unique result: (XRPLF#4877) * telENV_RPC_FAILED is a new code, reserved exclusively for unit tests when RPC fails. This will make those types of errors distinct and easier to test for when expected and/or diagnose when not. * Output RPC command result when result is not expected. * Fix workflows (XRPLF#4951) - Update container for Doxygen workflow. Matches Linux workflow, with newer GLIBC version required by newer actions. - Fixes macOS workflow to install and configure Conan correctly. Still fails on tests, but that does not seem attributable to the workflow. * perf: improve `account_tx` SQL query: (XRPLF#4955) The witness server makes heavily use of the `account_tx` RPC command. Perf testing showed that the SQL query used by `account_tx` became unacceptably slow when the DB was large and there was a `marker` parameter. The plan for the query showed only indexed reads. This appears to be an issue with the internal SQLite optimizer. This patch rewrote the query to use `UNION` instead of `OR` and significantly improves performance. See RXI-896 and RIPD-1847 for more details. * `fixEmptyDID`: fix amendment to handle empty DID edge case: (XRPLF#4950) This amendment fixes an edge case where an empty DID object can be created. It adds an additional check to ensure that DIDs are non-empty when created, and returns a `tecEMPTY_DID` error if the DID would be empty. * Enforce no duplicate slots from incoming connections: (XRPLF#4944) We do not currently enforce that incoming peer connection does not have remote_endpoint which is already used (either by incoming or outgoing connection), hence already stored in slots_. If we happen to receive a connection from such a duplicate remote_endpoint, it will eventually result in a crash (when disconnecting) or weird behavior (when updating slot state), as a result of an apparently matching remote_endpoint in slots_ being used by a different connection. * Remove zaphod.alloy.ee hub from default server list: (XRPLF#4903) Remove the zaphod.alloy.ee hubs from the bootstrap and default configuration after 5 years. It has been an honor to run these servers, but it is now time for another entity to step into this role. The zaphod servers will be taken offline in a phased manner keeping all those who have peering arrangements informed. These would be the preferred attributes of a boostrap set of hubs: 1. Commitment to run the hubs for a minimum of 2 years 2. Highly available 3. Geographically dispersed 4. Secure and up to date 5. Committed to ensure that peering information is kept private * Write improved `forAllApiVersions` used in NetworkOPs (XRPLF#4833) * Don't reach consensus as quickly if no other proposals seen: (XRPLF#4763) This fixes a case where a peer can desync under a certain timing circumstance--if it reaches a certain point in consensus before it receives proposals. This was noticed under high transaction volumes. Namely, when we arrive at the point of deciding whether consensus is reached after minimum establish phase duration but before having received any proposals. This could be caused by finishing the previous round slightly faster and/or having some delay in receiving proposals. Existing behavior arrives at consensus immediately after the minimum establish duration with no proposals. This causes us to desync because we then close a non-validated ledger. The change in this PR causes us to wait for a configured threshold before making the decision to arrive at consensus with no proposals. This allows validators to catch up and for brief delays in receiving proposals to be absorbed. There should be no drawback since, with no proposals coming in, we needn't be in a huge rush to jump ahead. * fixXChainRewardRounding: round reward shares down: (XRPLF#4933) When calculating reward shares, the amount should always be rounded down. If the `fixUniversalNumber` amendment is not active, this works correctly. If it is not active, then the amount is incorrectly rounded up. This patch introduces an amendment so it will be rounded down. * Remove unused files * Remove packaging scripts * Consolidate external libraries * Simplify protobuf generation * Rename .hpp to .h * Format formerly .hpp files * Rewrite includes $ find src/ripple/ src/test/ -type f -exec sed -i 's:include\s*["<]ripple/\(.*\)\.h\(pp\)\?[">]:include <ripple/\1.h>:' {} + * Fix source lists * Add markers around source lists * fix: improper handling of large synthetic AMM offers: A large synthetic offer was not handled correctly in the payment engine. This patch fixes that issue and introduces a new invariant check while processing synthetic offers. * Set version to 2.1.1 * chore: change Github Action triggers for build/test jobs (XRPLF#4956) Github Actions for the build/test jobs (nix.yml, mac.yml, windows.yml) will only run on branches that build packages (develop, release, master), and branches with names starting with "ci/". This is intended as a compromise between disabling CI jobs on personal forks entirely, and having the jobs run as a free-for-all. Note that it will not affect PR jobs at all. * Address compiler warnings * Fix search for protoc * chore: Default validator-keys-tool to master branch: (XRPLF#4943) * master is the default branch for that project. There's no point in using develop. * Remove unused lambdas from MultiApiJson_test * fix Conan component reference typo * Set version to 2.2.0-b2 * bump version * 2.2.3 * 2.2.4 * 2.2.5 --------- Co-authored-by: Gregory Tsipenyuk <gregtatcam@users.noreply.github.com> Co-authored-by: seelabs <scott.determan@yahoo.com> Co-authored-by: Chenna Keshava B S <21219765+ckeshava@users.noreply.github.com> Co-authored-by: Mayukha Vadari <mvadari@gmail.com> Co-authored-by: John Freeman <jfreeman08@gmail.com> Co-authored-by: Bronek Kozicki <brok@incorrekt.com> Co-authored-by: Ed Hennis <ed@ripple.com> Co-authored-by: Olek <115580134+oleks-rip@users.noreply.github.com> Co-authored-by: Alloy Networks <45832257+alloynetworks@users.noreply.github.com> Co-authored-by: Mark Travis <mtrippled@users.noreply.github.com> Co-authored-by: Gregory Tsipenyuk <gtsipenyuk@ripple.com>
