NOTE All other debug namespace APIs EXCEPT FOR the following APIs are restricted with rpc.unsafe-debug.disable flag:

  • VM Tracing APIs, however with limited functionality (only pre-defined tracers are allowed)

  • debug_dumpBlock, debug_dumpStateTrie, debug_getBlockRlp, debug_getModifiedAccountsByHash, debug_getModifiedAccountsByNumber, debug_getBadBlocks, debug_getModifiedStorageNodesByNumber

  • debug_metrics

debug_dumpBlock

Retrieves the state that corresponds to the block number and returns a list of accounts (including storage and code).

NOTE: This function correctly returns the state for a few latest, currently 4, block numbers. Retrieving older block state is restricted depending on the value set for the command-line option --state.block-interval (default: 128). This means that the function performs the state retrieval against only the block numbers that are multiples of state.block-interval. For example, when state.block-interval is 128, this function returns the state for the block numbers "0x0", "0x80", "0x100", "0x180", and so on. If the block number is not a multiple of state.block-interval, it returns 'missing trie node' error.

debug_startWarmUp

The startWarmUp iterates the latest state trie to warm-up the trie cache. The iteration will be automatically stopped if 90% of the trie cache is full. The method returns an error if it fails in starting a warm-up, or null if it successfully has started it.

debug_startCollectingTrieStats

The startCollectingTrieStats iterates the latest state or storage trie to collect trie statistics. It collects storage trie statistics of the contract in the given address. If an empty address(="0x00...00") is given, it collects statistics of the whole state trie. Statistics will be logged every minute before end, containing overall and depth-by-depth information. The method returns an error if it fails in starting a task, or null if it successfully has started it.
