cosmos/loadtest/cmd/loadtest/main.go (1)
1-10: Consider load testing best practicesAs this is the entry point for a load testing tool, consider implementing:
- Signal handling for graceful shutdown
- Resource cleanup on exit
- Metrics collection and reporting
- Configuration validation before test execution
Example implementation for graceful shutdown:
func main() { rootCmd := loadtest.NewCmd() // Setup signal handling sigChan := make(chan os.Signal, 1) signal.Notify(sigChan, syscall.SIGINT, syscall.SIGTERM) // Run command in a goroutine errChan := make(chan error, 1) go func() { errChan <- rootCmd.Execute() }() // Wait for either command completion or interrupt select { case err := <-errChan: if err != nil { rootCmd.PrintErrln(err) } case <-sigChan: // Perform cleanup fmt.Println("\nReceived interrupt, shutting down...") // Add cleanup logic here } }cosmos/loadtest/interface.go (1)
5-10: Add godoc comments for better documentation.Consider adding godoc comments to document the interface and its methods. This will improve code maintainability and help other developers understand the purpose and expected behavior of each method.
Here's the suggested documentation:
+// RPCClient defines the interface for interacting with a Cosmos SDK node +// through RPC calls during load testing. type RPCClient interface { + // GetAddressPrefix returns the bech32 address prefix for the chain GetAddressPrefix() (string, error) + // QueryAccount retrieves account information for the given address QueryAccount(address string) (types.AccountI, error) + // GetChainId returns the chain identifier GetChainId() (string, error) + // QuerySupply returns the total supply of coins on the chain QuerySupply() (types.Coins, error) }cosmos/loadtest/scripts/tq.py (1)
1-19: Consider architectural improvementsAs this script is part of the load testing infrastructure and handles configuration files:
- Consider extracting the conversion logic into separate functions for better modularity and testing
- Add unit tests to verify the conversion logic
- Consider adding logging for better debugging in the CI/CD pipeline
- Document the script's role in the load testing process
Would you like me to help with implementing any of these improvements?
cosmos/watcher/types.go (1)
10-16: Add field documentation and consider memory optimization.While the struct is well-structured, consider the following improvements:
- Add documentation comments for the struct and each field to improve code maintainability
- Consider whether storing both
TxsHashand fullTxsis necessary, as it could be memory-intensive for blocks with many transactionsExample documentation:
+// Block represents a blockchain block with its transactions and metadata. type Block struct { + // ChainID is the unique identifier of the blockchain ChainID string `json:"chain_id"` + // Height represents the block number in the chain Height int64 `json:"height"` + // BlockTime is the timestamp when the block was created BlockTime time.Time `json:"block_time"` + // TxsHash contains the hashes of all transactions in the block TxsHash []bytes.HexBytes `json:"txs_hash"` + // Txs contains the full transaction data Txs []*tx.Tx `json:"txs"` }cosmos/decode_tx.go (1)
8-8: Add function documentation and improve named returns usage.Consider adding godoc-style documentation explaining the function's purpose, parameters, and return values. Also, either utilize the named return parameter
ttxor remove it for consistency.+// DecodeTx decodes a raw transaction byte slice using the provided codec. +// It returns the decoded transaction and any error encountered during decoding. +// Parameters: +// - cdc: Binary codec for unmarshaling +// - txBytes: Raw transaction bytes func DecodeTx(cdc codec.BinaryCodec, txBytes []byte) (ttx *tx.Tx, err error) {cosmos/loadtest/scripts/address.py (2)
1-3: Remove extra blank lineA single blank line after imports is sufficient according to PEP 8.
import bech32 -
15-24: Add docstrings and complete type hintsThe helper methods need proper documentation and complete type hints.
- def get_hrp(self) -> str: + def get_hrp(self) -> str: + """Return the human-readable prefix of the address. + + Returns: + str: The human-readable prefix + """ return self._hrp - def to_string(self, hrp: str) -> str: + def to_string(self, hrp: str | None = None) -> str: + """Convert the address to its bech32 string representation. + + Args: + hrp: Optional human-readable prefix.

16-33: Enhance test coverage with additional scenarios.The current test only covers the basic startup/shutdown flow. Consider adding:
- Test cases for configuration validation
- Verification of specific error types from group.Wait()
- Server state verification during operation
- Error scenarios (e.g., invalid configuration)
Example enhancement:
func TestNewServer(t *testing.T) { tests := []struct { name string config func() *Config setupMock func() RPCClient wantErr bool errContains string }{ { name: "valid configuration", config: NewDefConfig, setupMock: func() RPCClient { return MockRpcClient{} }, wantErr: true, }, // Add more test cases } // ... test implementation }cosmos/mapstructure_decode_hook.go (1)
11-13: Enhance function documentation for better maintainability.Consider expanding the documentation to include:
- Purpose and behavior of each decode hook
- Expected input/output types
- Usage examples
Example improvement:
-// CustomDecodeHook is a custom decode hook for mapstructure +// CustomDecodeHook returns a decode hook for mapstructure that handles the following conversions: +// - string -> types.Coin: Parses normalized coin strings (e.g., "100stake") +// - string -> tx.BroadcastMode: Converts broadcast mode strings to their enum values +// - string -> types.DecCoin: Parses decimal coin strings (e.g., "100.5stake") +// +// Example usage: +// decoder, err := mapstructure.NewDecoder(&mapstructure.DecoderConfig{ +// DecodeHook: CustomDecodeHook(), +// Result: &result, +// })cosmos/watcher/config.go (2)
6-6: Consider using standard errors packageThe
github.com/pkg/errorspackage is deprecated. Consider using the standarderrorspackage from Go 1.13+ which provides similar functionality including wrapping errors.- "github.com/pkg/errors" + "errors"
25-33: LGTM! Consider adding configuration documentationThe default values are reasonable. Consider adding a README.md in the watcher package documenting these default values and their implications.
cosmos/loadtest/msg_send.go (1)
22-26: Consider improving parameter validation and configuration flexibility.A few suggestions for improvement:
- Add validation for the
denomparameter to ensure it's not empty- Consider making gas values configurable rather than hardcoded
- Document that the function modifies the passed
baseInfoparameterHere's a suggested improvement:
+// NewMsgSendClientFactory creates a new MsgSendClientFactory instance. +// Note: This function modifies the passed baseInfo parameter. func NewMsgSendClientFactory(baseInfo *BaseInfo, denom string) (*MsgSendClientFactory, error) { + if denom == "" { + return nil, fmt.Errorf("denom cannot be empty") + } + if baseInfo == nil { + return nil, fmt.Errorf("baseInfo cannot be nil") + } baseInfo.GasLimit = 100000 baseInfo.GasPrice = types.NewCoin(baseInfo.GetDenom(), sdkmath.NewInt(1)) return &MsgSendClientFactory{BaseInfo: baseInfo, denom: denom} }cosmos/loadtest/msg_send_test.go (1)
50-69: Enhance benchmark documentation and cleanup
- The benchmark comment should explain the purpose and expected outcomes.
- Consider adding cleanup of test resources after benchmark completion.
- Similar to the previous function, avoid hardcoding paths.
-// go test -bench ^Benchmark_NewMsgSendTxsAndMarshal$ -benchtime 10s -count 1 -cpu 1 -run=^$ -benchmem +// Benchmark_NewMsgSendTxsAndMarshal measures the performance of transaction creation and marshaling. +// It creates test transactions using genesis accounts and measures the time taken for creation and encoding. +// +// Usage: +// go test -bench ^Benchmark_NewMsgSendTxsAndMarshal$ -benchtime 10s -count 1 -cpu 1 -run=^$ -benchmem +// +// Metrics: +// - Time: Transaction creation and marshaling duration +// - Memory: Allocation statistics for transaction operations func Benchmark_NewMsgSendTxsAndMarshal(b *testing.B) { b.Skip("skip load test") - homeDir := os.ExpandEnv("$HOME") - keyDir := filepath.Join(homeDir, "test_accounts") + keyDir := os.Getenv("KEY_DIR") + if keyDir == "" { + keyDir = filepath.Join(os.ExpandEnv("$HOME"), "test_accounts") + } + defer os.RemoveAll(keyDir) // Clean up test accounts after benchmark - genesisFilePath := filepath.Join(homeDir, ".simapp", "config", "genesis.json") + genesisFilePath := os.Getenv("GENESIS_FILE_PATH") + if genesisFilePath == "" { + genesisFilePath = filepath.Join(os.ExpandEnv("$HOME"), ".simapp", "config", "genesis.json") + }cosmos/loadtest/scripts/local_chain.sh (1)
12-51: Consider parameterizing configuration values.The
update_configfunction contains many hardcoded configuration values that might need adjustment for different environments or test scenarios.Consider moving these values to a configuration file or environment variables:
+# Load configuration from environment or defaults +MEMPOOL_MAX_TXS=${MEMPOOL_MAX_TXS:-"10000"} +MEMPOOL_SIZE=${MEMPOOL_SIZE:-"10000"} +MEMPOOL_MAX_BYTES=${MEMPOOL_MAX_BYTES:-"1073741824"} + update_config() { # ... existing code ... - modify_toml "$APP_HOME/config/app.toml" "mempool.\"max-txs\"" "10000" + modify_toml "$APP_HOME/config/app.toml" "mempool.\"max-txs\"" "$MEMPOOL_MAX_TXS" # ... apply similar changes for other hardcoded values ... }cosmos/loadtest/scripts/crypto.py (2)
19-43: Add docstrings to the PrivateKey class and its methods for better maintainabilityThe
PrivateKeyclass functions are implemented correctly. However, adding docstrings to the class and its methods would improve code readability and help other developers understand their purpose and usage.Consider adding docstrings like this:
class PrivateKey: """Represents a private key in the blockchain system.""" def __init__(self, key: bytes) -> None: """Initialize a PrivateKey with the given key.""" self._priv_key = key def to_bytes(self) -> bytes: """Get the private key as bytes.""" return self._priv_key def to_public_key(self) -> PublicKey: """Derive the public key associated with this private key. Returns: PublicKey: The corresponding public key. """ # Existing implementation... def to_address(self, hrp: str) -> str: """Generate the blockchain address associated with this private key. Args: hrp (str): Human-readable part of the address. Returns: str: The blockchain address. """ # Existing implementation... def sign(self, message_bytes: bytes) -> bytes: """Sign a message using this private key. Args: message_bytes (bytes): The message to sign. Returns: bytes: The signature. """ # Existing implementation...
36-42: Document or handle exceptions in thesignmethodThe
signmethod may raise exceptions during the signing process, such as due to an invalid private key or improper message format. Documenting these exceptions or adding exception handling will help users of this method manage errors appropriately.cosmos/loadtest/types.go (1)
26-30: Inconsistent parameter naming: 'chainId' vs 'chainID'The parameter
chainIdinnewBaseInfoshould be renamed tochainIDto match Go naming conventions and maintain consistency with the struct fieldChainID.Apply this diff to rename the parameter:
-func newBaseInfo(accounts *Accounts, chainId, denom string) *BaseInfo { +func newBaseInfo(accounts *Accounts, chainID, denom string) *BaseInfo { return &BaseInfo{ Accounts: accounts, - ChainID: chainId, + ChainID: chainID, GasPrice: types.NewCoin(denom, sdkmath.NewInt(0)), GasLimit: 100_000, Memo: fmt.Sprintf("loadtest_%s", chainID), } }cosmos/loadtest/cmd.go (2)
30-31: Remove commented-out code to improve code cleanlinessThe commented-out line
// return viper.WriteConfig()seems unnecessary. Removing it will enhance code readability.
51-51: Usecmd.Printlninstead offmt.Printlnfor consistent CLI outputConsider using
cmd.Println("init accounts success", baseInfo.Accounts.Len())to ensure consistent command-line output and better integration with Cobra commands.cosmos/loadtest/scripts/populate_genesis_accounts.py (4)
75-75: Usesys.exitinstead ofreturn print()Using
return print()does not terminate the script properly. Replace it withsys.exitto exit the program after printing the error message.Apply this diff:
if number_of_accounts < 1: - return print("\nNumber of accounts must be greater than 0\n") + print("\nNumber of accounts must be greater than 0\n") + sys.exit(1)
80-91: Add error handling for accessing nested dictionary keysThe code directly accesses nested keys in
genesis_filewithout checking for their existence. This can lead toKeyErrorexceptions if the genesis file structure is different or missing expected keys. Consider adding checks ortry-exceptblocks to handle missing keys gracefully.
65-69: Consider backing up the original genesis file before overwritingOverwriting the genesis file without a backup can lead to data loss if something goes wrong. Before writing the new genesis data, create a backup of the original file.
Apply this diff to add a backup step:
def write_genesis_file(genesis_json_file_path, data): print("Writing results to genesis file") + import shutil + backup_path = genesis_json_file_path + ".bak" + shutil.copyfile(genesis_json_file_path, backup_path) + print(f"Backup of the original genesis file created at {backup_path}") with open(genesis_json_file_path, 'w') as f: json.dump(data, f, indent=4)
71-77: Useargparsefor command-line argument parsingReplacing manual parsing with the
argparsemodule enhances command-line interface handling, provides automatic help messages, and improves code readability.Here’s how you can refactor using
argparse:+import argparse def main(): + parser = argparse.ArgumentParser(description="Populate genesis accounts.") + parser.add_argument("number_of_accounts", type=int, help="Number of accounts to create") + parser.add_argument("genesis_file_path", help="Path to the genesis JSON file") + args = parser.parse_args() + - args = sys.argv[1:] - number_of_accounts = int(args[0]) - if number_of_accounts < 1: - return print("\nNumber of accounts must be greater than 0\n") - genesis_file_path = args[1] + if args.number_of_accounts < 1: + print("\nNumber of accounts must be greater than 0\n") + sys.exit(1) + + number_of_accounts = args.number_of_accounts + genesis_file_path = args.genesis_file_pathcosmos/loadtest/account.go (1)
64-66: Typo in function name:IsFistAccountshould beIsFirstAccountThe method
IsFistAccountcontains a typographical error. The correct spelling should beIsFirstAccount.Apply this diff to fix the typo:
-func (a *Accounts) IsFistAccount() bool { +func (a *Accounts) IsFirstAccount() bool {

Let me analyze the findings and generate the final response.
Security review of external dependencies completed - No critical issues found
The verification revealed:
tq.pyis a simple TOML/JSON converter utility with no direct security concerns- Key handling follows standard Cosmos SDK practices:
- Uses test keyring backend explicitly
- Admin keys are stored in a controlled location (
$APP_HOME/config) - Implements standard cryptographic practices through
crypto.py
- No hardcoded secrets or credentials found in the scripts
The implementation aligns with blockchain development security practices for local testing environments.

41-43: Clarify the purpose of decrementing 'b.GasLimit'
In the BuildTx method, b.GasLimit is decremented when b.Accounts.IsFirstAccount() returns true. Please clarify the rationale behind modifying b.GasLimit in this manner. If BaseInfo is shared among goroutines, modifying b.GasLimit without synchronization could lead to data races.
Would you like to ensure that modifying b.GasLimit is thread-safe or consider using a local variable instead?
51-53: Ensure thread safety when incrementing 'account.Sequence'
Incrementing account.Sequence may not be safe if Account instances are accessed concurrently across multiple goroutines. Please confirm that Account instances are not shared without proper synchronization.
If Account instances are shared, consider implementing synchronization mechanisms or redesigning to avoid concurrent access.

50-55: Confirm appropriateness of pub_key set to None
In the account dictionary, pub_key is set to None. Ensure that the blockchain application accepts accounts with pub_key set to None in the genesis file, and that this won't cause issues during chain initialization.
You can verify existing accounts with similar configurations by running:
Replace path/to/existing/genesis.json with the actual path to a known valid genesis file.
✅ Verification successful
Let's search for any genesis-related files or documentation that might help us understand the expected account structure.
Let's try to find more context about genesis account configurations in the codebase.
Let's examine these files to understand how genesis accounts are handled in the test environment.
Setting pub_key to None is appropriate for genesis accounts
Based on the code analysis, setting pub_key to None in the genesis accounts is correct because:
- This is part of a loadtest setup script that creates test accounts in bulk for chain initialization
- The script is actively used in
local_chain.shfor initializing test chains - The accounts are properly structured as
cosmos.auth.v1beta1.BaseAccounttypes - Public keys are not required in genesis accounts as they can be set later when the accounts first sign transactions
🏁 Scripts executed
The following scripts were executed for the analysis:

Initialize slices before copying data to prevent panics.
When copying transaction hashes into txsHash[i], the slice txsHash[i] is not initialized, which may cause a panic. Assign the hash directly instead of using copy.
Apply this diff to fix the issue:
txHash := sha256.Sum256(txsData[i])
- copy(txsHash[i], txHash[:])
+ txsHash[i] = txHash[:]Likely invalid or redundant comment.

53-62: Modify 'NextAccount' to use a write lock instead of a read lock
The function NextAccount is using RLock while modifying the cacheIndex, which can lead to race conditions. Modifying shared data should use Lock for thread safety.
95-102: Avoid using panic in goroutines; handle errors appropriately
Using panic inside goroutines can cause the entire program to crash unexpectedly. Instead, handle errors gracefully by collecting them or logging appropriately.

17-24: Add field documentation for better maintainability.Consider adding documentation comments for each field in the
BaseInfostruct to explain their purpose and expected values.type BaseInfo struct { + // Accounts manages the test accounts for load testing Accounts *Accounts + // ChainID identifies the blockchain network ChainID string + // GasPrice defines the cost per gas unit GasPrice types.Coin + // GasLimit sets the maximum gas allowed per transaction GasLimit uint64 + // Memo contains a transaction description Memo string + // EnableSequence controls automatic sequence number incrementing EnableSequence bool }
26-34: Consider making default values configurable.The hard-coded values for
GasLimit(100,000) and memo format could be made configurable through parameters or environment variables for better flexibility in different testing scenarios.
61-74: Improve error handling and messages.Consider providing more descriptive error messages that indicate what makes the input invalid. Also, consider wrapping errors with context using
fmt.Errorforerrors.Wrap.- return nil, errors.New("invalid base info") + return nil, fmt.Errorf("invalid base info: input %q is neither a genesis file path nor a valid URL", genesisOrUrl)
102-116: Consider moving genesis structure to a separate type definition.The anonymous struct definition makes the code harder to maintain and reuse. Consider moving it to a named type at package level.
+type GenesisConfig struct { + ChainId string `json:"chain_id"` + AppState struct { + Mint struct { + Params struct { + MintDenom string `json:"mint_denom"` + } `json:"params"` + } `json:"mint"` + Staking struct { + Params struct { + BondDenom string `json:"bond_denom"` + } `json:"params"` + } `json:"staking"` + } `json:"app_state"` +}cosmos/watcher/server.go (2)
24-27: Consider extending RPCClient interface with context-aware methodsThe current RPCClient interface methods don't accept context parameters, which could be important for timeout and cancellation handling in long-running operations.
Consider updating the interface to include context:
type RPCClient interface { - TxByHash(txHash string) (*types.TxResponse, error) - GetLatestBlock() (*cmtservice.Block, error) + TxByHash(ctx context.Context, txHash string) (*types.TxResponse, error) + GetLatestBlock(ctx context.Context) (*cmtservice.Block, error) }
182-208: Enhance error handling with custom error typesThe current error handling uses generic errors. Consider implementing custom error types for better error handling and recovery strategies.
Example implementation:
+// Define custom error types +type BlockFetchError struct { + Height int64 + Err error +} + +func (e *BlockFetchError) Error() string { + return fmt.Sprintf("failed to fetch block at height %d: %v", e.Height, e.Err) +} + +type TxDecodeError struct { + Index int + Err error +} + +func (e *TxDecodeError) Error() string { + return fmt.Sprintf("failed to decode transaction at index %d: %v", e.Index, e.Err) +} + func (s *Server) fetchBlock() (block Block, err error) { newBlock, err := s.client.GetLatestBlock() if err != nil { - return block, errors.Wrap(err, "failed to get latest block") + return block, &BlockFetchError{Height: -1, Err: err} } txsData := newBlock.Data.Txs txsHash := make([]bytes.HexBytes, len(txsData)) txs := make([]*tx.Tx, len(txsData)) for i := 0; i < len(txsData); i++ { txs[i], err = cosmos.DecodeTx(s.codec, txsData[i]) if err != nil { - return block, errors.Wrap(err, "failed to decode tx") + return block, &TxDecodeError{Index: i, Err: err} } txHash := sha256.Sum256(txsData[i]) copy(txsHash[i], txHash[:]) }cosmos/go.mod (2)
207-210: Review replace directives carefullyMultiple core dependencies are being replaced with custom forks:
- cosmos-sdk → crypto-org-chain/cosmos-sdk
- go-ethereum → functionx/go-ethereum
- ethermint → functionx/ethermint
This approach:
- Makes the build less reproducible
- May introduce compatibility issues
- Could miss security updates from upstream
Consider:
- Documenting why each replacement is necessary
- Setting up a process to regularly sync with upstream
- Planning for eventual migration back to upstream versions
Also applies to: 212-218
1-205: Consider dependency management improvementsRecommendations for better dependency management:
- Add a go.sum file for dependency verification
- Consider using workspace mode if this is part of a larger monorepo
- Document the minimum required Go version in README
- Set up automated dependency updates (e.g., using Dependabot)

Implement graceful shutdown and prevent goroutine leaks
The worker pool implementation could lead to goroutine leaks during shutdown. Consider implementing a proper cleanup mechanism.
Suggestions:
- Add a done channel for graceful shutdown
- Close and drain the pools channel during shutdown
- Add timeout for worker pool shutdown
Example implementation:
func (s *Server) scanBlock(ctx context.Context) error {
wg := sync.WaitGroup{}
pools := make(chan struct{}, s.config.BatchHandler)
+ done := make(chan struct{})
+ defer close(done)
+
+ // Create cleanup function
+ cleanup := func() {
+ close(pools)
+ // Add timeout for shutdown
+ shutdownCtx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
+ defer cancel()
+
+ // Wait with timeout
+ ch := make(chan struct{})
+ go func() {
+ wg.Wait()
+ close(ch)
+ }()
+
+ select {
+ case <-ch:
+ s.logger.Info("all workers completed successfully")
+ case <-shutdownCtx.Done():
+ s.logger.Warn("shutdown timeout reached, some workers may not have completed")
+ }
+ }
+ defer cleanup()Committable suggestion skipped: line range outside the PR's diff.

🛠️ Refactor suggestion
Simplify and strengthen block height validation logic
The current block height initialization logic is complex and could be made more robust.

- Consolidate validation checks
- Add bounds checking
- Use constants for special values

+ const (
+ MinBlockHeight = 1
+ AutoStartHeight = -1

return 0, errors.Wrap(err, "failed to get latest block")
}
latestBlockHeight := block.Header.Height
- if s.config.StartBlockHeight <= -1 {
+
+ // Validate and normalize block heights
+ if s.config.StartBlockHeight == AutoStartHeight {
s.config.StartBlockHeight = latestBlockHeight
+ } else if s.config.StartBlockHeight < MinBlockHeight {
+ return 0, errors.Errorf("invalid start block height: %d", s.config.StartBlockHeight)
