x/logic/util/slice.go (1)
- 1-10: The
Mapfunction is a generic function that applies a given function to each element of a slice and returns a new slice with the results. This is a common utility function that can be used in various scenarios where a transformation needs to be applied to each element of a slice. The function is well-written and follows Go's best practices for writing generic functions. It uses theanytype constraint introduced in Go 1.18, which allows it to work with any type that satisfies the empty interface. The function is also efficient as it preallocates the slice that will hold the results, avoiding unnecessary memory allocations.x/logic/predicate/util_test.go (1)
- 84-188: The new test function
TestTermToBytesis well-structured and covers a wide range of scenarios for theTermToBytesfunction. It tests different types of terms and options, and checks for both successful conversions and expected errors. The use of table-driven tests makes the code clean and easy to understand. The error messages are clear and informative, which will be helpful for debugging if a test fails. Good job on writing comprehensive tests.x/logic/predicate/crypto_test.go (2)
103-114: The test case has been updated to reflect the new error message when an integer value in the list is out of byte range. This is a more specific error message than the previous one, which is a good improvement. However, it's important to ensure that the function handling this error can properly handle this new error message.
175-377: The new test function
TestXVerifyis introduced to test theeddsa_verifyandecdsa_verifyfunctions. The test cases cover various scenarios, including successful verification, wrong message, wrong public key, wrong signature, and unsupported algorithm. This is a comprehensive set of tests that should cover most edge cases. However, it's important to ensure that these tests are run and pass successfully before merging the changes.x/logic/predicate/util.go (4)
1-7: The import of
"encoding/hex"is new in this hunk. It's used for hexadecimal encoding and decoding in theTermToBytesfunction. This change is consistent with the PR summary.10-25: The import of
"github.com/okp4/okp4d/x/logic/util"is new and is used for theGetOptionWithDefaultfunction in theTermToBytesfunction. The global variablesAtomEncoding,AtomHex, andAtomOctetare also new and are used in theTermToBytesfunction to specify encoding options. This change is consistent with the PR summary.80-119: The
TermToBytesfunction is new and is used to convert a term to a byte slice with different encoding options. The function uses theGetOptionWithDefaultfunction from theutilpackage to get the encoding option from the options term. It then checks the type of the encoding and the term and converts the term to a byte slice based on the encoding option. This function is well-structured and handles errors properly. However, it might be a good idea to break this function into smaller functions for better readability and maintainability.121-142: The
ListToBytesfunction has been updated to include an index variable and error messages that include the position of the invalid term in the list. This change improves error handling and debugging.x/logic/util/prolog.go (4)
10-16: The introduction of
AtomDotandAtomEmptyas global variables is a good practice as it avoids creating new instances of these common atoms every time they are needed. This can improve performance and memory usage.23-33: The
ResolveToAtomfunction has been modified to return an error instead of a boolean. This is a good practice as it provides more information about what went wrong when the function fails. However, ensure that all calls to this function throughout the codebase have been updated to handle the error.- func Resolve(env *engine.Env, t engine.Term) (engine.Atom, bool) { + func ResolveToAtom(env *engine.Env, t engine.Term) (engine.Atom, error) {
54-57: The
IsListfunction is a useful utility for checking if a compound is a list. It improves readability by encapsulating the logic for checking if a compound is a list.107-116: The
GetOptionWithDefaultfunction is a useful utility for getting an option with a default value. It improves code readability by encapsulating the logic for getting an option and providing a default value if the option is not found.x/logic/predicate/crypto.go (5)
38-38: The package name for the crypto library has been changed from "crypto" to "cometcrypto". Ensure that this change is intentional and that the new package provides the same functionality as the old one.
99-154: The new functions
EdDSAVerifyandECDSAVerifyhave been added. They provide signature verification functionality for the EdDSA and ECDSA algorithms respectively. Ensure that these functions are tested thoroughly, especially since they deal with cryptographic operations.156-206: The function
xVerifyhas been added. It provides a generic implementation for signature verification. This function is used by bothEdDSAVerifyandECDSAVerify, which pass specific parameters to it. This is a good example of code reuse and modularity.173-178: The code checks if the provided algorithm is supported. If it's not, an error is returned. This is a good practice as it ensures that only supported algorithms are used.
195-202: The function
util.VerifySignatureis used to verify the signature. If the verification fails, the function returnsengine.Bool(false). This is a good practice as it allows the caller to handle the failure case.x/logic/util/crypto.go (1)
- 28-32: The use of
recoverin adeferblock is a good practice to catch any panic that might occur during the execution ofVerifySignature. However, it's important to note that this will only catch panics that occur within the same goroutine. IfVerifySignatureis called in a new goroutine, panics in that goroutine will not be caught by thisrecover. Ensure that this behavior is intended and understood.

14-18: The new constant
DIDPrefixis introduced to represent the prefix for a DID. This is a good practice as it improves readability and maintainability of the code. If the prefix changes in the future, it can be updated in one place.37-37: The example for reconstructing a DID from its components has been updated. The null value has been replaced with an underscore (
_). Ensure that this change is intentional and aligns with the expected behavior of thedid_componentsfunction.71-98: The code for constructing a DID string from its components has been refactored to use a slice of functions (
processors). Each function in the slice corresponds to a specific segment of the DID and handles the processing of that segment. This is a good practice as it improves the modularity and readability of the code. However, ensure that the order of the functions in the slice matches the order of the segments in the DID.112-126: The
processSegmentfunction has been introduced to process a segment of a DID. This function takes a function as an argument and applies it to the segment. This is a good practice as it improves the modularity of the code and allows for more flexible processing of the segments. However, ensure that the function passed as an argument is always safe to call and handles all possible values of the segment.

IsListfunction is a useful utility for checking if a given compound is a list. It's simple and straightforward.59-105: The
GetOptionfunction is well-implemented. It handles both single options and lists of options, and it provides detailed error messages when things go wrong. However, it might be more efficient to break this function into smaller functions to improve readability and maintainability.107-116: The
GetOptionWithDefaultfunction is a useful utility for getting an option with a default value. It's simple and straightforward.

1-10: The import section looks clean and organized. All the necessary packages for cryptographic operations and error handling are imported.
12-18: The
Algtype and itsStringmethod are well implemented. This provides a clear way to represent the algorithm used for cryptographic operations.20-24: The constants for the supported algorithms are well defined. This makes it easy to use these algorithms in the code.
48-64: The
verifySignatureWithCurvefunction is well implemented. It correctly handles the unmarshalling of the public key and the verification of the signature. The error handling is also well done, with a clear error message when the public key cannot be parsed.

- 26-44: The
VerifySignaturefunction has been improved to handle the case where the length of the public key is not[PublicKeySize]. This is a good practice as it prevents unexpected panics from occurring due to an invalid public key size. The function now checks the public key size before it's used in theed25519.Verifyfunction. This change enhances the robustness and reliability of the function.x/logic/predicate/crypto_test.go (2)
175-377: The new test suite
TestXVerifyis a comprehensive set of tests for theeddsa_verifyandecdsa_verifyfunctions. It covers various scenarios including valid and invalid inputs, different encoding types, and different cryptographic algorithms. The tests are well-structured and provide clear error messages for failure cases. However, it would be beneficial to add a few more test cases to cover edge cases, such as empty or null inputs, and extremely large inputs. This will ensure the robustness of the functions under test.103-114: The test cases for the
hex_bytesfunction have been updated to include more detailed error messages. This is a good improvement as it provides more context when a test fails. However, the error message in line 113 seems to be inconsistent with the input data. The error message indicates an issue with the integer value 345 at position 1, but the input data has the string 'hey' at position 2. Please verify if the error message is correct.

…mponents Aligned with Swi-Prolog's behavior for the `uri_components` predicate, `DIDComponents` now strictly mandates components to be of type atom, introducing a breaking change.
