The tracing interface has been extended with backwards-compatible changes to support more use-cases and simplify tracer code. The most notable changes are state read hooks as well a state journaling library which emits events when a call is reverted. +### Deprecated methods + +- `OnSystemCallStart()`: This hook is deprecated in favor of `OnSystemCallStartV2(vm *VMContext)`. + ### New methods -- `OnReorg(reverted []*types.Block)`: This hook is called when a reorg is detected. The `reverted` slice contains the blocks that are no longer part of the canonical chain. - `OnBalanceRead(addr common.Address, balance *big.Int)`: This hook is called when an account balance is read. - `OnNonceRead(addr common.Address, nonce uint64)`: This hook is called when an account nonce is read. - `OnCodeRead(addr common.Address, code []byte)`: This hook is called when an account code is read. @@ -16,10 +19,7 @@ The tracing interface has been extended with backwards-compatible changes to sup - `OnCodeHashRead(addr common.Address, codeHash common.Hash)`: This hook is called when an account code hash is read. - `OnStorageRead(addr common.Address, slot common.Hash, value common.Hash)`: This hook is called when an account storage slot is read. - `OnBlockHashRead(blockNum uint64, hash common.Hash)`: This hook is called when a block hash is read by EVM. - -### Modified methods - -- `OnSystemCallStart()` -> `OnSystemCallStart(vm *VMContext)`.
