Changelog

• New invalid RLP ROM error support
• Fix ECRecover for case posUsed=-1 in native main executor code
• Add old state root and old batch number in executor response trace.
• Rename error to result in executor response trace.
• Create config.logExecutorServerInputJson to log input.json always before executing.
• Add thread ID to log traces
• Fix the log of the configuration parameters at boot time, showing always the important ones, and shortening config.databaseURL
• Improve DatabaseMap performance by not to copying the [key,value] pairs when not needed
• Delete config.dbMultiWriteSinglePosition, no longer needed since now we have config.stateManager to activate the equivalent funcionality
• Add a call to CheckTree() with new state root to executor test client, enabled if config.executorClientCheckNewStateRoot=true
• New StateManager component that groups all new hashes creation and deletion within the processing of a batch. This is enabled via config.stateManager=true, and purges unnecessary (deleted) hashes if config.stateManagerPurge=true
• Fix Database.read() logic to save multiWrite read data to cache
• New DatabasePerformanceTest to test database performance based on value size. Enabled via config.runDatabasePerformanceTest=true
• New CheckTree test that climbs a tree from root to all leafs, searching for missing hashes or wrong data content. Test is activated with config.runCheckTreeTest=true, and root is specified using config.checkTreeRoot (if “auto”, last state root saved to database is used)
• New associative database cache, activated with config.useAssociativeCache=true
• Fix database cache attempts and hits counters
• StateManager to update state root when flushing
• Database sender thread to retry after 5 seconds if connection to database was lost
• Split long database queries into several smaller ones after passing config.dbMultiWriteSingleQuerySize
• Enable generated code for fork 4 main executor

Prover v2.1.0 config changes

• New elements
  -- stateManager: boolean to activate the state manager (default=false) (set to true)
  -- useAssociativeCache: if true, an associative database cache is used (default=false) (set to true)

• New elements that normally should not be used
  -- executorClientCheckNewStateRoot: boolean to check the new state root returned by executor server (default=false)
  -- stateManagerPurge: boolean to purge deleted hashed during flush (default=true)
  -- runDatabasePerformanceTest: boolean to activate the database performance test (default=false)
  -- runCheckTreeTest: boolean to activate the check tree test (default=false)
  -- checkTreeRoot: string, root to use in check tree test, set to auto to get last state root from database (default=”auto”)
  -- dbMultiWriteSingleQuerySize: size in bytes that triggers to use a new database query and close the current one to be sent to database (default=20971520=20MB)
  -- logExecutorServerInputJson: boolean, set to true to log input before executing, in json format (default=false)

• Deleted elements, no longer supported
  -- dbMultiWriteSinglePosition: use stateManager instead
