cosmos/x/evm/keeper/abci.go (2)

• 34-46: The EndBlock method now includes additional logic to retrieve the EVM block and check if it matches the current block number. Additionally, a call to SetFinalizedBlock has been added. Ensure that the logic for retrieving and comparing the block number is correct and that the new call to SetFinalizedBlock is properly handled.
• 50-52: The PrepareCheckState method now includes a call to PrimePlugins. Verify that this new call is correctly implemented and that it does not introduce any side effects or performance issues.

Verification successful

---

The PrimePlugins method is correctly implemented, as it prepares the plugins by setting their context without introducing any side effects or performance issues based on the provided implementations of the Prepare method for both the historical and block plugins. The mock implementations are also standard for testing purposes.

eth/params/chain_config.go (1)

• 30-38: The DefaultEIP155ChainID constant has been reassigned to artioChainID with a value of 80085. This change affects the default chain configuration for Ethereum. Confirm that this new chain ID is intended and correctly applied throughout the codebase.

proto/polaris/evm/v1alpha1/tx.proto (1)

• 55-55: The Status enum and the status field have been removed from the WrappedEthereumTransactionResult message. This is a significant change in how transaction statuses are handled. Ensure that all parts of the codebase that interact with transaction statuses are updated to work with the new structure.

Verification successful

---

The search for the enum Status { pattern did not yield any results, which suggests that the Status enum has been removed from the codebase. Additionally, the search for the message WrappedEthereumTransactionResult { pattern returned a result from proto/polaris/evm/v1alpha1/tx.proto, confirming that the WrappedEthereumTransactionResult message is present but does not include any fields within the braces, which aligns with the removal of the status field as indicated in the PR objectives and the AI-generated summary.

Based on the provided script outputs, it can be concluded that the Status enum and the status field have been removed from the WrappedEthereumTransactionResult message in the tx.proto file, consistent with the changes described in the review comment.

cosmos/x/evm/keeper/genesis.go (1)

• 46-49: The InitGenesis function now sets the genesis context before writing the genesis block to the chain. Confirm that this change is consistent with the intended genesis process and that it does not affect the initialization of the chain adversely.

cosmos/x/evm/keeper/keeper.go (2)

• 42-43: The Keeper struct now includes a new field txpool *txpool.Mempool. Ensure that this new field is properly initialized and used throughout the keeper's methods.
• 66-68: The Setup method's signature has been updated to accept an additional parameter txPool *txpool.Mempool. Verify that all calls to Setup have been updated to pass the new parameter and that the txpool is correctly integrated into the keeper's logic.

Verification successful

---

The search within cosmos/runtime/runtime.go has confirmed that the Setup method is being called with the new txPool parameter, as shown by the line:

if err := ek.Setup(p.WrappedBlockchain, p.WrappedTxPool); err != nil {

This line indicates that the Setup method is being invoked with two parameters: p.WrappedBlockchain and p.WrappedTxPool, which aligns with the updated method signature that includes the txPool *txpool.Mempool parameter.

Based on this information, it can be concluded that the Setup method's signature has been correctly updated and the calls to Setup have been adjusted to pass the new txPool parameter. The txpool appears to be correctly integrated into the keeper's logic in the cosmos/runtime/runtime.go file.

cosmos/x/evm/genesis_test.go (1)

• 67-73: > Note: This review was outside the patches, so it was mapped to the patch with the greatest overlap. Original lines [70-87]

The assignment of the cfg variable has been changed from config.DefaultConfig() to config.DefaultPolarisConfig(), which aligns with the PR objectives to update configuration management. Additionally, a nil argument is now passed to the chain.New function call, which suggests a change in the initialization pattern of the chain. Ensure that the chain.New function is designed to handle a nil argument without issues.

cosmos/x/evm/plugins/state/factory.go (2)

• 100-106: The NewPluginAtBlockNumber method's signature has been changed to accept an int64 instead of a uint64. This change should be verified across the codebase to ensure that all calls to this method have been updated accordingly.

Verification successful

---

The NewPluginAtBlockNumber method's signature has been updated to accept an int64 in the interface definition and the call site found in eth/core/chain_resources.go has been updated to use an int64 as well. No other calls to this method with the old uint64 type were found in the codebase. Therefore, it appears that the necessary updates have been made in accordance with the changes to the method signature.

Scripts Executed

The following scripts were executed for the analysis:

---

eth/core/host.go (2)

• 60-60: The comment for the BlockPlugin interface's Prepare method has been updated to clarify its behavior. This change is minor and does not affect the functionality.
• 80-80: The NewPluginAtBlockNumber method in the StatePluginFactory interface now takes an int64 parameter instead of a uint64. This change should be verified across the codebase to ensure that all calls to this method have been updated accordingly.

Verification successful

---

The change to the NewPluginAtBlockNumber method parameter from uint64 to int64 has been reflected in the codebase. The method definitions and the call site in chain_resources.go have been updated to use int64, as verified by the search results.

e2e/testapp/polard/cmd/root.go (3)

• 35-35: The evmconfig package has been renamed to polarconfig, and references have been updated accordingly. This change is consistent with the PR objectives to update configuration management.
• 68-68: The function PolarisConfigFn is now called with polarconfig.DefaultPolarisConfig() instead of evmconfig.DefaultConfig(). This change is consistent with the PR objectives to update configuration management.
• 118-118: The function RecommendedCometBFTConfig from the polarconfig package is used instead of initCometBFTConfig. Ensure that the RecommendedCometBFTConfig function provides the correct configuration for the Comet BFT consensus algorithm.

eth/eth.go (1)

• 57-57: The Remove method has been added to the TxPool interface, allowing the removal of transactions by hash. This change is consistent with the PR objectives to enhance transaction management.

cosmos/runtime/abci/proposal.go (2)

• 125-137: The code now includes calls to spf.SetLatestQueryContext(ctx) and spf.SetInsertChainContext(ctx) before processing the proposal. Additionally, there is a call to pp.wrappedBlockchain.PrimePlugins(ctx) after setting the insert chain context. Ensure that these context-setting methods and the PrimePlugins call are correctly implemented and that they do not introduce any race conditions or other issues.
• 160-167: The code now includes a check for an abort signal after beginBlock. This is a good practice to ensure that the process can be interrupted if necessary.

cosmos/runtime/txpool/mempool.go (2)

• 65-87: The Mempool struct now embeds eth.TxPool and introduces new fields to manage transaction lifetimes and removal. The New function's signature has been modified to accommodate these changes. Ensure that the eth.TxPool integration and the new fields are correctly used throughout the codebase.
• 110-142: The Insert and Remove methods have been updated to handle Ethereum transactions and interact with the embedded eth.TxPool and CometRemoteCache. Ensure that the logic for adding and removing transactions is correct and that it properly interacts with the eth.TxPool.

Verification successful

The Remove method is indeed present in the mempool.go file. To verify the logic within this method, we need to see the actual implementation. Since we have located the method signature, we can now request the contents of the Remove method to ensure it interacts correctly with the eth.TxPool.

---

The output provides a partial view of the Remove method's implementation in the mempool.go file. From the snippet, we can see that the method is designed to handle a Cosmos transaction (sdk.Tx) and attempts to extract an Ethereum payload envelope (WrappedPayloadEnvelope). If successful, it unwraps the payload to access the Ethereum transactions contained within.

To fully verify the logic of the Remove method, we need to see the complete implementation, especially how it interacts with the eth.TxPool. Let's extend the range of lines retrieved by rg to ensure we capture the entire method body.

---

The provided output shows more of the Remove method's implementation. It details the process of extracting Ethereum transactions from a Cosmos transaction and then performing operations on them. Specifically, it mentions:

1. Unwrapping the payload to access the Ethereum transactions.
2. Unmarshalling each Ethereum transaction.
3. Dropping the transaction from the CometRemoteCache (crc).
4. A comment indicating a conditional removal from the mempool based on a force removal setting.

However, the output is still incomplete, as it cuts off mid-comment. To fully understand the Remove method's interaction with eth.TxPool and to verify the logic, we need to see the rest of the method.

---

The complete Remove method implementation from mempool.go has been provided. The method performs the following actions:

1. It retrieves the Ethereum payload envelope from the Cosmos transaction.
2. It unwraps the payload to access the individual Ethereum transactions.
3. For each Ethereum transaction, it:
   • Unmarshals the transaction.
   • Calculates the transaction hash.
   • Drops the transaction from the CometRemoteCache using DropRemoteTx.
   • Conditionally removes the transaction from the eth.TxPool if forceTxRemoval is set to true.

The logic within the Remove method appears to be correct based on the provided code snippet. It properly interacts with both the CometRemoteCache and the eth.TxPool, with the latter interaction being conditional on the forceTxRemoval flag.

Based on the provided code and the verification process, the Insert and Remove methods in the Mempool struct handle Ethereum transactions as described and interact with the embedded eth.TxPool and CometRemoteCache as expected.

cosmos/config/flags/flags.go (1)

• 28-28: The addition of the ForceTxRemoval constant is consistent with the PR objectives and the AI-generated summary. It introduces a new configuration option for forceful transaction removal in the mempool.

e2e/testapp/polard/cmd/commands.go (3)

• 35-35: The import path github.com/berachain/polaris/cosmos/config has been updated to polarconfig, which aligns with the restructuring of the project's package structure.
• 64-69: The CustomAppConfig struct now includes a Polaris field of type polarconfig.Config, which is initialized with the DefaultPolarisConfig. This change is consistent with the PR objectives to introduce new configuration options.
• 72-72: The customAppTemplate variable concatenates the DefaultConfigTemplate with the PolarisConfigTemplate, which is expected as part of the configuration management updates.

eth/polar/backend.go (1)

• 145-147: The addition of a panic statement in case of an error when setting the extra data for the miner is a critical change. This ensures that the application will not run with an improperly configured miner, which is a crucial aspect for the correctness of the system.

cosmos/runtime/txpool/handler.go (4)

• 86-86: The addition of the CometRemoteCache field to the handler struct is consistent with the PR objectives to enhance the mempool's capabilities by managing transactions added remotely.
• 101-102: The newHandler function signature has been updated to include the CometRemoteCache parameter, which is necessary for the new functionality introduced in the mempool.
• 205-214: The broadcastTransactions method now includes logic to check if a transaction is remote before broadcasting it, and logs the number of transactions received and broadcasted. This is a significant change that aligns with the new mempool enhancements.
• 234-236: The change in the broadcastTransaction method to consider a response code of 1 as acceptable behavior is a logical update. It accounts for the scenario where a transaction is already in a block, and thus failing to broadcast is the correct outcome.

eth/core/chain_resources.go (1)

• 74-74: The StateAtBlockNumber function now casts the block number to an int64 instead of uint64 when calling NewPluginAtBlockNumber. This change should be verified to ensure that it does not introduce any issues with block number handling, especially considering the maximum value of int64 is less than uint64.

cosmos/runtime/runtime.go (5)

• 58-58: The EVMKeeper interface's Setup method has been updated to accept an additional parameter of type *txpool.Mempool. This change is necessary for the refactoring and updating of the mempool structure and its interaction with Ethereum transactions.
• 91-94: The addition of the blockBuilderMu field of type sync.RWMutex to the Polaris struct is a concurrency control mechanism to ensure thread safety during block building and transaction insertion into the mempool.
• 125-132: The initialization of p.WrappedTxPool has been updated to include new parameters, which is consistent with the changes made to the txpool.New function call. This is part of the mempool enhancements.
• 162-162: The Build method of the Polaris struct now passes p.WrappedTxPool as an argument to the ek.Setup call, which is necessary due to the changes in the EVMKeeper interface.
• 233-236: The LoadLastState method has been updated to set the latest query context and prime plugins for the blockchain. This is part of the enhancements to the EVM keeper logic and state management.

eth/core/chain_writer.go (5)

• 36-41: The ChainWriter interface has been updated with the removal of the context parameter from several methods and the addition of a new method SetFinalizedBlock. Ensure that all implementations of this interface are updated accordingly to reflect these changes.
• 60-67: The method InsertBlockAndSetHead has been updated to include an additional parameter. Verify that all calls to this method have been updated to pass the correct arguments.

Verification successful

---

The search with rg has identified two relevant lines in the codebase where the InsertBlockAndSetHead method is called or defined:

1. cosmos/runtime/chain/abci.go: if err = wbc.InsertBlockAndSetHead(block); err != nil {
2. eth/core/chain_writer.go:func (bc *blockchain) InsertBlockAndSetHead(block *ethtypes.Block) error {

From the output, it appears that the method InsertBlockAndSetHead is called with a single argument in cosmos/runtime/chain/abci.go, which matches the updated method signature in eth/core/chain_writer.go. There are no calls to this method with an incorrect number of arguments.

Based on this information, it can be concluded that all calls to the InsertBlockAndSetHead method have been updated to pass the correct number of arguments as per the changes in the pull request.

* 96-125: > Note: This review was outside the patches, so it was mapped to the patch with the greatest overlap. Original lines [72-113]

The method insertBlockAndSetHead has been updated with additional logic for firing events. Ensure that the logic for emitting events is correct and that it does not introduce any race conditions or performance issues.

• 116-122: The method InsertBlock has been refactored to remove redundant comments and adjust the logic for finalizing blocks. Ensure that the refactoring does not alter the intended behavior of the method.
• 243-250: A new method SetFinalizedBlock has been added to the blockchain struct. Verify that this method is being called in the correct context and that it correctly updates the state of the blockchain.

Verification successful

---

The SetFinalizedBlock method is indeed being called within the codebase. The search results show that it is called in the file cosmos/x/evm/keeper/abci.go. This indicates that the method is used in the correct context to update the state of the blockchain, specifically within the EVM keeper logic during the ABCI (Application Blockchain Interface) process.

Verification successful

---

The logic for setting the ExtraData field in the Miner configuration is verified to be as described in the review comment. The Git commit hash is retrieved and a subset of it is used to populate ExtraData if it is initially empty. The check for the commit hash length being 40 characters ensures that a full SHA-1 hash is being used.

eth/polar/api_backend.go (2)

• 326-327: The modification to the StateAndHeaderByNumber method to check for both block and state being nil before returning a "pending state is not available" error is a logical improvement. This ensures that the method does not proceed with a nil state, which could lead to unexpected behavior or crashes.
• 339-339: The change from pcore.ErrBlockNotFound to pcore.ErrHeaderNotFound when a header is not found is more accurate and provides clearer information about the error condition.

eth/core/mock/state_plugin.mock.go (1)

• 73-78: > Note: This review was outside the patches, and no patch overlapping with it was found. Original lines [1-1]

The file state_plugin.mock.go is a generated mock file and should not be manually edited. Ensure that the generation of this file is part of the automated build or a pre-commit hook to maintain consistency.

contracts/bindings/testing/governance/governance_wrapper.abigen.go (4)

• 83-83: The GovernanceWrapperMetaData variable has been updated with new ABI and binary data.

This change is expected as part of the smart contract update process to reflect the new contract interface and bytecode.

• 83-83: The DeployGovernanceWrapper function now uses GovernanceWrapperMetaData.

This update is correct and aligns with the use of the new contract metadata structure.

• 83-83: The contract wrapper definitions (caller, transactor, filterer, and sessions) appear consistent with the updated metadata.

The definitions are correctly using the new GovernanceWrapperMetaData and no discrepancies were found.

• 83-83: The contract method bindings are auto-generated and should match the updated ABI.

The method bindings such as Bank, GetProposal, Submit, Vote, and Receive are correctly reflecting the new ABI.

cosmos/api/polaris/evm/v1alpha1/tx.pulsar.go (1)

• 1217-1217: The removal of the Status enum from WrappedEthereumTransactionResult aligns with the PR objectives to refactor transaction result statuses.

[coderabbitai]

The GovernanceWrapperABI and GovernanceWrapperBin variables are marked as deprecated.

Replace any usage of these deprecated variables with GovernanceWrapperMetaData.ABI and GovernanceWrapperMetaData.Bin to ensure the codebase is up-to-date with the latest contract ABI and bytecode.

[coderabbitai]

A comment has been added to verify the version of the app CMS against app.LastBlockHeight during the loading of the last state. Ensure that this verification is implemented and tested to prevent inconsistencies.

Would you like me to implement this verification check or open a GitHub issue to track this task?

[coderabbitai]

The search for inline comments near the force-tx-removal references has provided a comment in the template.go file that explains the purpose of the force-tx-removal configuration option. The comment states:

# ForceTxRemoval indicates whether we use Cosmos to remove transactions from the Geth txpool.

This comment serves as inline documentation for the configuration option within the codebase. However, there were no additional explanatory comments or documentation found in the vicinity of the reference in the flags.go file.

Given this context, it can be concluded that while there is a brief inline comment explaining the force-tx-removal option in the template.go file, there is no extensive documentation or user guide found in the Markdown files or other documentation files in the repository. Therefore, the review comment is correct in suggesting that the usage of this option should be clearly documented for end-users.
