⚠️ Potential issueClarify comment or adjust implementation for NewByte32FromBytesPaddingZero.
The implementation of
NewByte32FromBytesPaddingZerocorrectly zero-pads shorter inputs. However, the comment suggests that the function also truncates longer inputs, which is not implemented in the function.Consider either:
- Updating the comment to accurately reflect the current implementation:
// create bytes32 with zero-padding for shorter bytes
- Or, implement the truncation as mentioned in the comment:
func NewByte32FromBytesPaddingZero(b []byte) *Byte32 { byte32 := new(Byte32) if len(b) > 32 { copy(byte32[:], b[:32]) } else { copy(byte32[:], b) } return byte32 }trie/zk_trie_impl_test.go (3)

Use
assert.NoErrorinstead ofassert.Nilwhen checking for errors.When verifying that an error has not occurred, it's more appropriate to use
assert.NoError(t, err)as it provides clearer failure messages and is semantically correct for error handling.Apply this change to all relevant lines:

91-92:
⚠️ Potential issueCheck for errors before using returned values to prevent unexpected behavior.
After calling
root, err := mt.Root(), ensure that you check for errors before proceeding to useroot. This prevents potential nil pointer dereferences or unexpected behavior if an error occurs.Update the code to handle errors appropriately:
root, err := mt.Root() - assert.NoError(t, err) + if err != nil { + t.Fatalf("Failed to retrieve trie root: %v", err) + }This ensures that the test fails gracefully with a clear error message if

157-157: 🛠️ Refactor suggestion
Enhance test coverage by using more diverse key inputs.
The test uses repeated single-character keys, which might not adequately simulate real-world scenarios. Consider using a wider range of keys to ensure the trie handles various inputs correctly.
Modify the test keys to include more diversity:
- for i, key := range []string{"a", "j", "l", "z"} { + testKeys := []string{"a", "aa", "abc", "xyz", "longerkeyvalue", ""} + for i, key := range testKeys {This provides a broader spectrum of test cases, enhancing the robustness of your tests.

🧹 Outside diff range and nitpick comments (64)
trie/byte32.go (1)
37-42: LGTM: NewByte32FromBytesPaddingZero function is correctly implemented. Minor comment improvement suggested.The function correctly implements the described behavior.
Consider updating the comment to more explicitly state the difference in padding behavior compared to
NewByte32FromBytes:-// create bytes32 with zeropadding to shorter bytes, or truncate it +// create bytes32 with zero-padding at the end for shorter bytes, or truncate longer bytestrie/byte32_test.go (3)
10-30: LGTM: Well-structured table-driven tests.The test function is well-structured using a table-driven approach, which is efficient for testing multiple scenarios. The test cases cover different input sizes, which is good for edge case testing.
Consider adding a test case for an empty input ([]byte{}) to ensure the methods handle this edge case correctly.
32-43: LGTM: Comprehensive test execution and assertions.The test execution loop is well-structured, covering all necessary assertions to validate the functionality of both methods and their
Hashoperations.Consider adding descriptive messages to the assertions to improve test failure diagnostics. For example:
assert.Equal(t, tt.expected, byte32Result.Bytes(), "NewByte32FromBytes result mismatch")
1-44: Overall: Well-structured and comprehensive test file.This test file provides good coverage for the
Byte32functionality, including both byte array results and their hash representations. The use of table-driven tests with hard-coded expected values ensures robustness against implementation changes.To improve maintainability, consider extracting the test cases into a separate variable or even a separate function. This would make it easier to add or modify test cases in the future without cluttering the main test function. For example:
var byte32TestCases = []struct { input []byte expected []byte expectedPaddingZero []byte expectedHash string expectedHashPadding string }{ // ... (existing test cases) ... } func TestNewByte32(t *testing.T) { for _, tt := range byte32TestCases { // ... (existing test logic) ... } }trie/hash_test.go (5)
14-23: LGTM: TestCheckBigIntInField covers key edge cases.The test function effectively checks the
CheckBigIntInFieldfunction for important edge cases: zero, the largest valid value (Q-1), and the first invalid value (Q). The use ofassertfrom the testify package is appropriate for these unit tests.Consider adding a few more test cases:
- A small positive number (e.g., 1 or 10) to test a typical valid input.
- A negative number to ensure it's handled correctly (likely should return false).
- A very large number well beyond Q to test upper bound handling.
25-62: LGTM: Comprehensive testing of hash and big integer conversions.This test function covers a wide range of scenarios for hash and big integer conversions, including normal cases and error handling. The use of both
assertandrequireis appropriate for different test cases.To improve readability and maintainability, consider breaking this large test function into smaller, more focused test functions. For example:
TestNewHashFromBytesTestNewHashFromCheckedBytesTestNewBigIntFromHashBytesTestHashMarshalUnmarshalTestNewHashFromBytesErrorsTestNewBigIntFromHashBytesErrorsThis separation would make it easier to understand and maintain each specific test case.
64-75: LGTM: Good coverage of hash conversions from big integers and strings.The test function effectively checks the conversion of both small integers and large string representations to hash objects. The assertions for both hexadecimal and string representations are appropriate.
Consider adding the following test cases to improve coverage:
- Test with a negative big integer to ensure proper handling.
- Test with a string that's not a valid number to check error handling in
NewHashFromString.- Test with a big integer that's out of the valid field range to ensure proper error handling in
NewHashFromBigInt.
77-83: LGTM: Good test for NewHashFromBytes with random input.The test function effectively checks the
NewHashFromBytesfunction using random input, ensuring the correct number of bytes are read and that the resulting hash matches the input.Consider adding an error check for the
NewHashFromBytesfunction call:h2 := NewHashFromBytes(h.Bytes()) require.NotNil(t, h2, "NewHashFromBytes should not return nil") require.Equal(t, h, *h2)This addition would ensure that
NewHashFromBytesdoesn't return an unexpected nil value.
1-83: Overall: Excellent test coverage with minor improvement suggestions.This new test file provides comprehensive coverage for hash-related functions in the trie package. The tests are well-structured, follow Go conventions, and effectively use the testify package for assertions. They cover both normal cases and error scenarios, which is crucial for robust testing.
To further improve this already solid test file:
- Consider breaking down larger test functions (e.g.,
TestNewHashAndBigIntFromBytes) into smaller, more focused tests for better maintainability.- Add a few more edge cases to some test functions as suggested in previous comments.
- Ensure consistent error handling across all test functions.
These minor enhancements will make the test suite even more robust and easier to maintain in the future.
trie/util_test.go (7)
23-47: LGTM: TestBitManipulations is comprehensive.The test provides excellent coverage for both
TestBitandTestBitBigEndianfunctions, correctly handling the difference between standard and big-endian bit ordering.Consider using a table-driven test to reduce code duplication and make it easier to add more test cases in the future. For example:
func TestBitManipulations(t *testing.T) { bitmap := []byte{0b10101010, 0b01010101} testCases := []struct { name string testFunc func([]byte, uint) bool expected []bool }{ { name: "TestBit", testFunc: TestBit, expected: []bool{false, true, false, true, false, true, false, true, true, false, true, false, true, false, true, false}, }, { name: "TestBitBigEndian", testFunc: TestBitBigEndian, expected: []bool{true, false, true, false, true, false, true, false, false, true, false, true, false, true, false, true}, }, } for _, tc := range testCases { t.Run(tc.name, func(t *testing.T) { results := make([]bool, 16) for i := uint(0); i < 16; i++ { results[i] = tc.testFunc(bitmap, i) } assert.Equal(t, tc.expected, results) }) } }This approach makes the test more maintainable and easier to extend.
49-54: LGTM: TestBigEndianBitsToBigInt is correct.The test effectively verifies the conversion from big-endian bit representation to integer.
Consider adding an additional test case with a different bit pattern to increase coverage. For example:
func TestBigEndianBitsToBigInt(t *testing.T) { testCases := []struct { name string bits []bool expected *big.Int }{ { name: "Alternating bits", bits: []bool{true, false, true, false, true, false, true, false}, expected: big.NewInt(170), }, { name: "Random pattern", bits: []bool{true, true, false, true, false, false, true, true}, expected: big.NewInt(211), }, } for _, tc := range testCases { t.Run(tc.name, func(t *testing.T) { result := BigEndianBitsToBigInt(tc.bits) assert.Equal(t, tc.expected, result) }) } }This approach provides better coverage and makes it easier to add more test cases in the future.
56-60: LGTM: TestToSecureKey verifies basic functionality.The test correctly checks for the absence of errors and the expected output for a given input.
Consider adding the following improvements:
- Test with multiple input values to ensure consistent behavior.
- Include a test case with an empty input to verify edge case handling.
- Add a negative test case to check error handling for invalid inputs.
Example:
func TestToSecureKey(t *testing.T) { testCases := []struct { name string input []byte expected string expectError bool }{ { name: "Valid input", input: []byte("testKey"), expected: "10380846131134096261855654117842104248915214759620570252072028416245925344412", }, { name: "Empty input", input: []byte{}, expected: "0", // Adjust this based on the expected behavior for empty input }, { name: "Invalid input", input: []byte{0xFF, 0xFF, 0xFF}, // Adjust based on what constitutes an invalid input expectError: true, }, } for _, tc := range testCases { t.Run(tc.name, func(t *testing.T) { secureKey, err := ToSecureKey(tc.input) if tc.expectError { assert.Error(t, err) } else { assert.NoError(t, err) assert.Equal(t, tc.expected, secureKey.String()) } }) } }These additional test cases will provide more comprehensive coverage of the
ToSecureKeyfunction.
62-66: LGTM: TestToSecureKeyBytes verifies basic functionality.The test correctly checks for the absence of errors and the expected output for a given input.
Consider applying similar improvements as suggested for
TestToSecureKey:
- Test with multiple input values.
- Include a test case with an empty input.
- Add a negative test case for invalid inputs.
Example:
func TestToSecureKeyBytes(t *testing.T) { testCases := []struct { name string input []byte expected []byte expectError bool }{ { name: "Valid input", input: []byte("testKey"), expected: []byte{0x16, 0xf3, 0x59, 0xc7, 0x30, 0x7e, 0x8, 0x97, 0xdc, 0x7c, 0x6b, 0x99, 0x53, 0xd1, 0xe1, 0xd8, 0x3, 0x6d, 0xc3, 0x83, 0xd4, 0xa, 0x0, 0x19, 0x9e, 0xda, 0xf0, 0x65, 0x27, 0xda, 0xf4, 0x9c}, }, { name: "Empty input", input: []byte{}, expected: make([]byte, 32), // Adjust based on expected behavior for empty input }, { name: "Invalid input", input: []byte{0xFF, 0xFF, 0xFF}, // Adjust based on what constitutes an invalid input expectError: true, }, } for _, tc := range testCases { t.Run(tc.name, func(t *testing.T) { secureKeyBytes, err := ToSecureKeyBytes(tc.input) if tc.expectError { assert.Error(t, err) } else { assert.NoError(t, err) assert.Equal(t, tc.expected, secureKeyBytes.Bytes()) } }) } }These additional test cases will provide more comprehensive coverage of the
ToSecureKeyBytesfunction.
68-79: LGTM: TestHashElems provides a good basic check.The test effectively verifies the
HashElemsfunction with a mix of fixed and generated input values.Consider the following improvements to enhance test coverage:
- Add test cases with different numbers of elements (e.g., 0, 1, 31, 33) to verify edge cases.
- Include a test case with very large
big.Intvalues to ensure proper handling.- Add a negative test case to check error handling for invalid inputs.
Example:
func TestHashElems(t *testing.T) { testCases := []struct { name string fst *big.Int snd *big.Int elems []*big.Int expected string expectError bool }{ { name: "32 elements", fst: big.NewInt(5), snd: big.NewInt(3), elems: generateBigIntSlice(32, 1), expected: "0746c424799ef6ad7916511016a5b8e30688fa6d62664eeb97d9f2ba07685ed8", }, { name: "No elements", fst: big.NewInt(5), snd: big.NewInt(3), elems: []*big.Int{}, expected: "expectedHashForNoElements", // Replace with actual expected hash }, { name: "Large values", fst: new(big.Int).Exp(big.NewInt(2), big.NewInt(256), nil), snd: new(big.Int).Exp(big.NewInt(2), big.NewInt(256), nil), elems: []*big.Int{new(big.Int).Exp(big.NewInt(2), big.NewInt(256), nil)}, expected: "expectedHashForLargeValues", // Replace with actual expected hash }, { name: "Invalid input", fst: nil, snd: big.NewInt(3), elems: []*big.Int{big.NewInt(1)}, expectError: true, }, } for _, tc := range testCases { t.Run(tc.name, func(t *testing.T) { result, err := HashElems(tc.fst, tc.snd, tc.elems...) if tc.expectError { assert.Error(t, err) } else { assert.NoError(t, err) assert.Equal(t, tc.expected, result.Hex()) } }) } } func generateBigIntSlice(length int, start int64) []*big.Int { slice := make([]*big.Int, length) for i := range slice { slice[i] = big.NewInt(start + int64(i)) } return slice }These additional test cases will provide more comprehensive coverage of the
HashElemsfunction, including edge cases and error handling.
81-96: LGTM: TestPreHandlingElems provides basic coverage.The test effectively checks the
HandlingElemsAndByte32function with both full and partial input arrays.Consider the following improvements to enhance test coverage and clarity:
- Use a table-driven test to make it easier to add more test cases.
- Add test cases with different flag arrays to verify the function's behavior under various conditions.
- Include a test case with an empty input array to check edge case handling.
- Add a negative test case to verify error handling for invalid inputs.
- Use more descriptive names for test cases to improve readability.
Example:
func TestHandlingElemsAndByte32(t *testing.T) { testCases := []struct { name string flagArray uint32 elems []Byte32 expected string expectError bool }{ { name: "Full array with alternating flags", flagArray: 0b10101010101010101010101010101010, elems: generateByte32Array(32), expected: "0c36a6406e35e1fec2a5602fcd80ab04ec24d727676a953673c0850d205f9378", }, { name: "Single element with all flags set", flagArray: 0xFFFFFFFF, elems: generateByte32Array(1), expected: "0000000000000000000000000000000000000000000000000000007465737431", }, { name: "Empty array with flags set", flagArray: 0xFFFFFFFF, elems: []Byte32{}, expected: "expectedHashForEmptyArray", // Replace with actual expected hash }, { name: "Invalid input: mismatched flag and elem count", flagArray: 0b1111, elems: generateByte32Array(32), expectError: true, }, } for _, tc := range testCases { t.Run(tc.name, func(t *testing.T) { result, err := HandlingElemsAndByte32(tc.flagArray, tc.elems) if tc.expectError { assert.Error(t, err) } else { assert.NoError(t, err) assert.Equal(t, tc.expected, result.Hex()) } }) } } func generateByte32Array(length int) []Byte32 { elems := make([]Byte32, length) for i := range elems { elems[i] = *NewByte32FromBytes([]byte("test" + strconv.Itoa(i+1))) } return elems }These improvements will provide more comprehensive coverage of the
HandlingElemsAndByte32function, including edge cases and error handling, while also improving the test's readability and maintainability.
1-96: Overall, trie/util_test.go provides good test coverage with room for improvement.The test file contains well-structured tests for various utility functions in the trie package. Each test function provides good basic coverage and uses appropriate assertions. The use of predetermined expected values ensures deterministic behavior of the utility functions.
To further enhance the quality and coverage of the tests, consider implementing the following improvements across all test functions:
- Use table-driven tests to improve readability and make it easier to add more test cases.
- Add edge cases (e.g., empty inputs, maximum values) to ensure robust function behavior.
- Include negative test cases to verify error handling for invalid inputs.
- Use more descriptive names for test cases to improve readability.
- Consider testing with a wider range of input values to ensure consistent behavior across different scenarios.
Implementing these suggestions will result in more comprehensive test coverage, improved maintainability, and increased confidence in the correctness of the trie package's utility functions.

140-172: Test logic adapted to new structure.The core test logic has been successfully adapted to the new sub-test structure. The conditional setting of
configbased ontt.eip3860is a good approach for testing both scenarios.For improved readability, consider extracting the
configinitialization into a separate function:func getConfig(eip3860 bool) Config { config := Config{} if eip3860 { config.ExtraEips = []int{3860} } return config }Then use it as:
config := getConfig(tt.eip3860)
178-182: Improved gas usage check for successful deployments.The addition of a condition to check gas usage only for successful deployments is a good improvement. It prevents unnecessary checks and aligns the test behavior more closely with real-world scenarios.
For added clarity, consider adding a comment explaining the significance of the 100_000 value:
// Only check gas usage if deployment succeeded (minGas < 100_000) // 100_000 is the maximum gas allowed for these test cases if minGas < 100_000 { if gasUsed != tt.gasUsed { t.Errorf("test %d: gas used mismatch: have %v, want %v", i, gasUsed, tt.gasUsed) } }core/chain_makers_test.go (1)

1-324: Summary: Address test coverage gap introduced by ZkTrie integrationThe changes in this file involve skipping two tests (
TestDumpandTestIterativeDump) due to ZkTrie not supporting iterators. While this addresses the immediate compatibility issue, it introduces a gap in test coverage for ZkTrie's Dump and IterativeDump functionalities.To maintain the integrity of the test suite and ensure proper functionality of ZkTrie, consider the following actions:
- Create technical debt tickets to track these skipped tests.
- Develop alternative testing strategies for ZkTrie that work within its current limitations.
- Update the existing tests or create new ones specifically for ZkTrie to ensure its Dump and IterativeDump functionalities are adequately tested.
- Consolidate the skip logic to improve maintainability.
By addressing these points, you can ensure that the integration of ZkTrie doesn't compromise the overall test coverage and quality of the codebase.

3-1010: Comprehensive snapshot test suite implementedThe test suite covers a wide range of scenarios for blockchain snapshot functionality, including:
- Normal restarts with valid snapshots
- Crashes with various commit points
- Gapped snapshots
- SetHead operations
- Wiping crashes
Each test case is well-documented with clear expectations and covers both the HashScheme and PathScheme.
The test suite appears to be thorough and well-implemented. It should provide good coverage for the snapshot functionality.
Some suggestions for potential improvements:
- Consider adding more edge cases, such as extremely long chains or chains with complex state.
- It might be beneficial to add some performance benchmarks for snapshot operations.
- Consider adding tests for concurrent operations on snapshots, if applicable.

192-192: Simplification of trie configuration looks good.The change to consistently use
trie.HashDefaultsfor the trie configuration simplifies the code and aligns with the broader refactoring of trie configurations. This is a good improvement.However, please verify that this change doesn't negatively impact any scenarios that previously relied on the
ZktrieEnabledcondition. Ensure that all relevant test cases still pass with this new configuration.
Line range hint
1-268: Overall changes simplify testing, but warrant a review of test coverage.The changes in this file align with the broader refactoring of trie configurations in the codebase. While they simplify the testing process, they also reduce test coverage in some areas, particularly for different genesis block scenarios.
To ensure the continued robustness of the testing suite:
- Review the overall test coverage for genesis block configurations and setups.
- Consider adding new test cases to cover any scenarios that might have been lost due to the commented-out tests.
