Conflux v1.1.5-testnet

Improvements

RPC Improvements

• Fix incorrect responses of cfx_getBlockRewardInfo. If the node needs to serve this RPC, it needs to clear all data and resync the chain.
• Simplify EVM revert reason in RPC responses. This may cause incompatible issues if the user was decoding the error messages manually.
• Add new RPC cfx_getBlockByBlockNumber.
• Add blockNumber to the returned JSON object in cfx_getBlockByHash, cfx_getBlockByEpochNumber, and cfx_getBlockByHashWithPivotAssumption.
• Accept pivot hash in cfx_getEpochReceipts.
• Raise error in cfx_getBlockByHashWithPivotAssumption if the provided block hash does not belong to the provided epoch.
• Fix returnData format of CallResult.
• Fix incorrect firstTxStatus response of cfx_getAccountPendingTransactions if start_nonce is provided.
• Update cfx_getCode so that it returns an empty hex 0x if the account does not exist instead of raising an error.

Configuration Improvement

• Add persist_block_number_index to persist block number indices. It allows responding to block-number-related RPC requests for old epochs.
• Add storage_max_open_mpt_count to configure maximal number of opened MPT.
