Types ¶
type ContextStack ¶
type ContextStack struct {
// contains filtered or unexported fields
}
ContextStack manages the initial context and a stack of cached contexts, to support the `StateDB.Snapshot` and `StateDB.RevertToSnapshot` methods.
func (*ContextStack) Commit ¶
func (cs *ContextStack) Commit()
Commit commits all the cached contexts from top to bottom in order and clears the stack by setting an empty slice of cache contexts.
func (*ContextStack) CurrentContext ¶
func (cs *ContextStack) CurrentContext() sdk.Context
CurrentContext returns the top context of cached stack, if the stack is empty, returns the initial context.
func (*ContextStack) IsEmpty ¶
func (cs *ContextStack) IsEmpty() bool
IsEmpty returns true if the cache context stack is empty.
func (*ContextStack) Reset ¶
func (cs *ContextStack) Reset(ctx sdk.Context)
Reset sets the initial context and clear the cache context stack.
func (*ContextStack) RevertAll ¶
func (cs *ContextStack) RevertAll()
RevertAll discards all the cache contexts.
func (*ContextStack) RevertToSnapshot ¶
func (cs *ContextStack) RevertToSnapshot(target int)
RevertToSnapshot pops all the cached contexts after the target index (inclusive). the target should be snapshot index returned by `Snapshot`. This function panics if the index is out of bounds.
func (*ContextStack) Snapshot ¶
func (cs *ContextStack) Snapshot() int
Snapshot pushes a new cached context to the stack, and returns the index of it.
type Keeper ¶
type Keeper struct {
// contains filtered or unexported fields
}
Keeper grants access to the EVM module state and implements the go-ethereum StateDB interface.
func NewKeeper ¶
func NewKeeper( cdc codec.BinaryCodec, storeKey, transientKey sdk.StoreKey, paramSpace paramtypes.Subspace, ak types.AccountKeeper, bankKeeper types.BankKeeper, sk types.StakingKeeper, tracer string, debug bool, ) *Keeper
NewKeeper generates new evm module keeper
func (Keeper) Account ¶
func (k Keeper) Account(c context.Context, req *types.QueryAccountRequest) (*types.QueryAccountResponse, error)
Account implements the Query/Account gRPC method
func (*Keeper) AddAddressToAccessList ¶
AddAddressToAccessList adds the given address to the access list. If the address is already in the access list, this function performs a no-op.
func (*Keeper) AddBalance ¶
AddBalance adds the given amount to the address balance coin by minting new coins and transferring them to the address. The coin denomination is obtained from the module parameters.
func (*Keeper) AddLog ¶
AddLog appends the given ethereum Log to the list of Logs associated with the transaction hash kept in the current context. This function also fills in the tx hash, block hash, tx index and log index fields before setting the log to store.
func (*Keeper) AddPreimage ¶
AddPreimage performs a no-op since the EnablePreimageRecording flag is disabled on the vm.Config during state transitions. No store trie preimages are written to the database.
func (*Keeper) AddSlotToAccessList ¶
AddSlotToAccessList adds the given (address, slot) to the access list. If the address and slot are already in the access list, this function performs a no-op.
func (*Keeper) AddressInAccessList ¶
AddressInAccessList returns true if the address is registered on the transient store.
func (*Keeper) ApplyMessage ¶
func (k *Keeper) ApplyMessage(evm *vm.EVM, msg core.Message, cfg *params.ChainConfig, query bool) (*types.MsgEthereumTxResponse, error)
ApplyMessage computes the new state by applying the given message against the existing state. If the message fails, the VM execution error with the reason will be returned to the client and the transaction won't be committed to the store.
Reverted state ¶
The transaction is never "reverted" since there is no snapshot + rollback performed on the StateDB. Only successful transactions are written to the store during DeliverTx mode.
Prechecks and Preprocessing ¶
All relevant state transition prechecks for the MsgEthereumTx are performed on the AnteHandler, prior to running the transaction against the state. The prechecks run are the following:
1. the nonce of the message caller is correct 2. caller has enough balance to cover transaction fee(gaslimit * gasprice) 3. the amount of gas required is available in the block 4. the purchased gas is enough to cover intrinsic usage 5. there is no overflow when calculating intrinsic gas 6. caller has enough balance to cover asset transfer for **topmost** call
The preprocessing steps performed by the AnteHandler are:
1. set up the initial access list (iff fork > Berlin)
Query mode ¶
The gRPC query endpoint from 'eth_call' calls this method in query mode, and since the query handler don't call AnteHandler, so we don't do real gas refund in that case.
func (*Keeper) ApplyTransaction ¶
func (k *Keeper) ApplyTransaction(tx *ethtypes.Transaction) (*types.MsgEthereumTxResponse, error)
ApplyTransaction runs and attempts to perform a state transition with the given transaction (i.e Message), that will only be persisted (committed) to the underlying KVStore if the transaction does not fail.
Gas tracking ¶
Ethereum consumes gas according to the EVM opcodes instead of general reads and writes to store. Because of this, the state transition needs to ignore the SDK gas consumption mechanism defined by the GasKVStore and instead consume the amount of gas used by the VM execution. The amount of gas used is tracked by the EVM and returned in the execution result.
Prior to the execution, the starting tx gas meter is saved and replaced with an infinite gas meter in a new context in order to ignore the SDK gas consumption config values (read, write, has, delete). After the execution, the gas used from the message execution will be added to the starting gas consumed, taking into consideration the amount of gas returned. Finally, the context is updated with the EVM gas consumed value prior to returning.
