From 6c24d9897ae63d2fb8f9d132b95fda2871e27ff2 Mon Sep 17 00:00:00 2001 From: David Date: Thu, 24 May 2018 17:29:28 +0200 Subject: [PATCH] Set the request index to that of the current request (#8683) * Set the request index to that of the current request When setting up the chain of (two) requests to look up a block by hash, the second need to refer to the first. This fixes an issue where the back ref was set to the subsequent request, not the current one. When the requests are executed we loop through them in order and ensure the requests that should produce headers all match up. We do this by index so they better be right. In other words: off by one. --- rpc/src/v1/helpers/light_fetch.rs | 3 +-- rpc/src/v1/tests/eth.rs | 12 ++++++++++++ 2 files changed, 13 insertions(+), 2 deletions(-) diff --git a/rpc/src/v1/helpers/light_fetch.rs b/rpc/src/v1/helpers/light_fetch.rs index 413670d52..1baf9a764 100644 --- a/rpc/src/v1/helpers/light_fetch.rs +++ b/rpc/src/v1/helpers/light_fetch.rs @@ -129,9 +129,8 @@ impl LightFetch { } } BlockId::Hash(h) => { - reqs.push(request::HeaderByHash(h.into()).into()); - let idx = reqs.len(); + reqs.push(request::HeaderByHash(h.into()).into()); Ok(HeaderRef::Unresolved(idx, h.into())) } _ => Err(errors::unknown_block()) // latest, earliest, and pending will have all already returned. diff --git a/rpc/src/v1/tests/eth.rs b/rpc/src/v1/tests/eth.rs index 4b83710bc..26117471c 100644 --- a/rpc/src/v1/tests/eth.rs +++ b/rpc/src/v1/tests/eth.rs @@ -204,6 +204,18 @@ fn eth_get_block() { assert_eq!(tester.handler.handle_request_sync(req_block).unwrap(), res_block); } +#[test] +fn eth_get_block_by_hash() { + let chain = extract_chain!("BlockchainTests/bcGasPricerTest/RPC_API_Test"); + let tester = EthTester::from_chain(&chain); + + // We're looking for block number 4 from "RPC_API_Test_Frontier" + let req_block = r#"{"method":"eth_getBlockByHash","params":["0x9c9bdab4cb53fd834e790b13545597f026494d42112e84c0aca9dd6bcc545295",false],"id":1,"jsonrpc":"2.0"}"#; + + let res_block = r#"{"jsonrpc":"2.0","result":{"author":"0x8888f1f195afa192cfee860698584c030f4c9db1","difficulty":"0x200c0","extraData":"0x","gasLimit":"0x1dd8112","gasUsed":"0x5458","hash":"0x9c9bdab4cb53fd834e790b13545597f026494d42112e84c0aca9dd6bcc545295","logsBloom":"0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000","miner":"0x8888f1f195afa192cfee860698584c030f4c9db1","mixHash":"0xaddea8d25bb0f955fa6c1d58d74ab8a3fec99d37943e2a261e3b12f97d6bff7c","nonce":"0x8e18bed16d5a88da","number":"0x4","parentHash":"0x2cbf4fc930c5b4c87598f43fc8eb26dccdab2f58a7d0d3ca92ec60a5444a330e","receiptsRoot":"0x7ed8026cf72ed0e98e6fd53ab406e51ffd34397d9da0052494ff41376fda7b5f","sealFields":["0xa0addea8d25bb0f955fa6c1d58d74ab8a3fec99d37943e2a261e3b12f97d6bff7c","0x888e18bed16d5a88da"],"sha3Uncles":"0x75cc08a7cb2cf8081446659fecb2633fb6b922d26edd59bd2272b1f5cae1c78b","size":"0x661","stateRoot":"0x68805721294e365020aca15ed56c360d9dc2cf03cbeff84c9b84b8aed023bfb5","timestamp":"0x59d662ff","totalDifficulty":"0xa0180","transactions":["0xb094b9dc356dbb8b256402c6d5709288066ad6a372c90c9c516f14277545fd58"],"transactionsRoot":"0x97a593d8d7e15b57f5c6bb25bc6c325463ef99f874bc08a78656c3ab5cb23262","uncles":["0xa1e9c9ecd2af999e0723aae1dc55dd9789ca618e0b34badcc8ac7d9a3dad3af2","0x81d429b6b6635214a2b0f976cc4b2ed49808140d6bede50129bc10d22ac9249e"]},"id":1}"#; + assert_eq!(tester.handler.handle_request_sync(req_block).unwrap(), res_block); +} + // a frontier-like test with an expanded gas limit and balance on known account. const TRANSACTION_COUNT_SPEC: &'static [u8] = br#"{ "name": "Frontier (Test)",
