Conflux v3.0.2

Bug Fixes

RPC

• Fix eth_call coinbase opcode: Fixed bug where eth_call coinbase opcode was using a random address instead of the correct one

Others

• Fix PoS reward reexecution: Fixed issue where PoS reward in DB was not checked if it's on pivot for reexecution

RPC Changes

New RPC Endpoints

• debug_blockProperties: Added a custom eSpace RPC endpoint to return extra block property information for all transactions in an eSpace block. This is useful for services that require verification of transaction execution, as transactions within a single Conflux eSpace block may have different block contexts (coinbase, timestamp, difficulty) during execution. See documentation for details.

RPC Improvements

• Log timestamp support: Added blockTimestamp field to eSpace log object (for methods like eth_getLogs and eth_getFilterLogs)
• Block number type improvements:
  • Renamed RPC type BlockNumber to BlockId for better precision
  • RPC type BlockNumber now supports block hash case
• Log format optimization: Optimized bytes log format from number array to hex string
• Fix parity trace compatibility: Fixed parity trace error and result structure incompatibility issue
• Fix block retrieval errors: Use new defined error types instead of strings for block retrieve methods
• RPC configuration: Added configuration options for eSpace RPCs

Performance Improvements

• Storage optimization: Optimized to only read from storage if entry is not occupied
• eth_feeHistory: Optimized to only read header instead of full block for base price calculation

Infrastructure & Dependencies

Memory Management

• jemalloc upgrade: Switched from jemallocator to tikv-jemallocator
• Memory profiling: Added memory and CPU pprof support for profiling
