depinject/errors.go (2)
Line range hint
25-32: LGTM with a minor suggestion: Consider using strings.Builder for error messageThe
Errormethod forErrMultipleImplicitInterfaceBindingsis well-implemented. It provides a detailed error message and correctly uses thefullyQualifiedTypeNamehelper function.Consider using
strings.Builderfor more efficient string concatenation, especially if the number of matches could be large:var b strings.Builder for _, m := range err.Matches { fmt.Fprintf(&b, "\n %s", fullyQualifiedTypeName(m)) } return fmt.Sprintf("Multiple implementations found for interface %v: %s", err.Interface, b.String())
Line range hint
56-65: LGTM with a minor suggestion: Consider using a single format stringThe
Errormethod forErrNoTypeForExplicitBindingFoundis well-implemented. It provides clear and informative error messages, handling cases with and without module names.Consider using a single format string with conditional formatting for the module name. This can make the code more concise and easier to maintain:
func (err ErrNoTypeForExplicitBindingFound) Error() string { return fmt.Sprintf("No type for explicit binding found. Given the explicit interface binding %s%s, a provider of type %s was not found.", err.Interface, map[bool]string{true: fmt.Sprintf(" in module %s", err.ModuleName), false: ""}[err.ModuleName != ""], err.Implementation) }crypto/keyring/autocli.go (1)
Line range hint
109-139: LGTM: New KeyInfo method added with good error handlingThe new
KeyInfomethod provides a flexible way to retrieve key information by handling both key names and addresses as input. The error handling is appropriate, and the logic for differentiating between name and address input is sound.Consider adding some inline comments to explain the logic flow, especially the differentiation between name and address input. For example:
// KeyInfo returns key name, key address, and key type given a key name or address. func (a *autoCLIKeyringAdapter) KeyInfo(nameOrAddr string) (string, string, uint, error) { // First, try to interpret the input as an address addr, err := a.ac.StringToBytes(nameOrAddr) if err != nil { // If conversion fails, treat the input as a key name // ... (existing code) } // If conversion succeeds, treat the input as an address // ... (existing code) }This would enhance the readability and maintainability of the code.

Line range hint
40-51: AppendStringDelimiterto buffer inEncodeNonTerminalThe
EncodeNonTerminalfunction is expected to writelen(key) + 1bytes tobuffer, but it currently writes onlylen(key)bytes. TheStringDelimiteris not appended to the buffer after the key, which may lead to decoding errors inDecodeNonTerminal.Apply this diff to append the
StringDelimiterto the buffer:func (stringKey[T]) EncodeNonTerminal(buffer []byte, key T) (int, error) { for i := range key { c := key[i] if c == StringDelimiter { return 0, fmt.Errorf("%w: string is not allowed to have the string delimiter (%c) in non-terminal encodings of strings", ErrEncoding, StringDelimiter) } buffer[i] = c } + buffer[len(key)] = StringDelimiter return len(key) + 1, nil }
Line range hint
40-51: Check buffer capacity before writing inEncodeNonTerminalTo prevent potential out-of-bounds writes, ensure that the provided
bufferhas sufficient capacity to holdlen(key) + 1bytes before writing to it. Without this check, writing beyond the buffer's capacity could cause runtime panics.Apply this diff to check the buffer capacity:
func (stringKey[T]) EncodeNonTerminal(buffer []byte, key T) (int, error) { + if len(buffer) < len(key)+1 { + return 0, fmt.Errorf("%w: buffer too small to encode key", ErrEncoding) + } for i := range key { c := key[i] if c == StringDelimiter { return 0, fmt.Errorf("%w: string is not allowed to have the string delimiter (%c) in non-terminal encodings of strings", ErrEncoding, StringDelimiter) } buffer[i] = c } buffer[len(key)] = StringDelimiter return len(key) + 1, nil }depinject/provider_desc.go (3)
50-51: Revise the function comment for clarityThe comment for
extractInvokerDescriptorcan be improved to better align with Go conventions. It is recommended to combine the two sentences into one concise sentence that starts with the function name and ends with a period.Apply this diff to revise the comment:
-// extractInvokerDescriptor extracts an invoker descriptor from a given provider function. -// It marks all inputs as optional. +// extractInvokerDescriptor extracts an invoker descriptor from a given provider function, marking all inputs as optional.
67-67: Use consistent parameter namingConsider renaming the parameter
ctrindoExtractProviderDescriptortoproviderfor consistency with the other functionsextractProviderDescriptorandextractInvokerDescriptor. This enhances readability and maintains uniformity across similar functions.Apply this diff to rename the parameter:
-func doExtractProviderDescriptor(ctr interface{}) (providerDescriptor, error) { +func doExtractProviderDescriptor(provider interface{}) (providerDescriptor, error) { val := reflect.ValueOf(provider) typ := val.Type()
Line range hint
85-87: Avoid using experimental packagesThe use of
slices.Containsfrom thegolang.org/x/exp/slicespackage introduces a dependency on experimental code that may change in future releases. To ensure stability and compatibility, consider implementing theContainsfunctionality without relying on experimental packages.Apply this diff to replace
slices.Containswith a standard implementation:-import ( "fmt" "reflect" "strings" "unicode" - "golang.org/x/exp/slices" ) ... - if slices.Contains(pkgParts, "internal") { + if contains(pkgParts, "internal") { return providerDescriptor{}, fmt.Errorf("function must not be in an internal package: %s", loc) } +// contains checks if a slice contains a specific string. +func contains(slice []string, item string) bool { + for _, s := range slice { + if s == item { + return true + } + } + return false +}depinject/struct_args.go (2)
38-39: Add periods at the end of sentences in commentsThe function comments should be complete sentences ending with a period, as per the Uber Go Style Guide.
Apply this diff to add periods at the end of the comments:
-// expandStructArgsProvider expands the inputs and outputs of a provider descriptor -// if they are structs that implement the In or Out interfaces. +// expandStructArgsProvider expands the inputs and outputs of a provider descriptor. +// If they are structs that implement the In or Out interfaces.
70-71: Add periods at the end of sentences in commentsEnsure that comments are complete sentences ending with a period, following the Uber Go Style Guide.
Apply this diff:
-// expandStructArgsFn returns a new function that handles struct arguments -// for both inputs and outputs of the provider. +// expandStructArgsFn returns a new function that handles struct arguments for both inputs and outputs of the provider.crypto/keys/bcrypt/bcrypt.go (7)

133-155: Simplify the return statement innewFromPassword.The function
newFromPasswordalways returnserrasnilat the end since any error would have caused an earlier return. You can simplify the return statement by returningnildirectly.Apply the following diff to simplify the code:
func newFromPassword(salt, password []byte, cost uint32) (*hashed, error) { // ... existing code ... p.hash = hash - return p, err + return p, nil }
Line range hint
157-185: Simplify the return statement innewFromHash.Similar to
newFromPassword, theerrvariable at the end ofnewFromHashis alwaysnil. You can simplify the return statement.Apply the following diff:
func newFromHash(hashedSecret []byte) (*hashed, error) { // ... existing code ... return p, nil }
Line range hint
186-207: Consider variable scoping for loop indices inbcrypt.The loop variables
iandjcan be limited in scope by declaring them within the for-loops. This enhances readability and maintains narrower variable scopes.Apply the following diff:
func bcrypt(password []byte, cost uint32, salt []byte) ([]byte, error) { // ... existing code ... - for i := 0; i < 24; i += 8 { - for j := 0; j < 64; j++ { + for i := 0; i < 24; i += 8 { + for j := 0; j < 64; j++ { c.Encrypt(cipherData[i:i+8], cipherData[i:i+8]) } }
Line range hint
208-234: Avoid unnecessary slicing inexpensiveBlowfishSetup.In the line
ckey := append(key[:len(key):len(key)], 0), the slicing can be simplified unless there's a specific need for full slice expressions. This makes the code cleaner and easier to understand.Apply the following diff:
- ckey := append(key[:len(key):len(key)], 0) + ckey := append(key, 0)
Line range hint
258-275: Handle potential out-of-range slice access indecodeVersion.In
decodeVersion, accessingsbytes[2]assumes thatsbyteshas at least three elements. Add a check to prevent a potential panic when the hashed password is malformed.Apply the following diff to add a length check:
func (p *hashed) decodeVersion(sbytes []byte) (int, error) { if sbytes[0] != '$' { return -1, InvalidHashPrefixError(sbytes[0]) } if sbytes[1] > majorVersion { return -1, HashVersionTooNewError(sbytes[1]) } p.major = sbytes[1] - n := 3 + n := 2 if len(sbytes) > 2 && sbytes[2] != '$' { p.minor = sbytes[2] n++ } return n, nil }
289-293: Implement error interface if appropriate inStringmethod.Consider whether the
Stringmethod forhashedshould implement theerrorinterface. Ifhashedrepresents an error state, implementing theError()method could be more appropriate.
Line range hint
294-298: Consolidate cost validation in one place.The
checkCostfunction validates the cost parameter. Ensure that all places where the cost is set or modified call this function to maintain consistent validation.depinject/container.go (5)
Line range hint
81-83: Improve cyclic dependency error message for better debugging.In the error handling for cyclic dependencies:
if c.callerMap[loc] { return nil, fmt.Errorf("cyclic dependency: %s -> %s", loc.Name(), loc.Name()) }Both instances of
loc.Name()are the same, which may not provide sufficient information to identify the cycle. Consider enhancing the error message to include the sequence of calls or the full call stack to aid in debugging cyclic dependencies.
Line range hint
98-175: Consider optimizing interface resolution ingetResolvermethod.In the
getResolvermethod, when resolving interfaces without explicit bindings, the code performs a linear search over all registered resolvers:if typ.Kind() == reflect.Interface { matches := map[reflect.Type]reflect.Type{} var resolverType reflect.Type for _, r := range c.resolvers { if r.getType().Kind() != reflect.Interface && r.getType().Implements(typ) { resolverType = r.getType() matches[resolverType] = resolverType } } // ... }This approach could become inefficient as the number of resolvers increases. Consider maintaining a map of interfaces to their implementing types to optimize the lookup process and improve performance.
Line range hint
274-276: Typographical error in error message.In the error message when both
ModuleKeyandOwnModuleKeyare declared as dependencies:return nil, fmt.Errorf("%T and %T must not be declared as dependencies on the same provided", ModuleKey{}, OwnModuleKey{})The word "provided" should be "provider". Correct the error message as follows:
-return nil, fmt.Errorf("%T and %T must not be declared as dependencies on the same provided", ModuleKey{}, OwnModuleKey{}) +return nil, fmt.Errorf("%T and %T must not be declared as dependencies on the same provider", ModuleKey{}, OwnModuleKey{})
Line range hint
395-398: Avoid contractions in error messages for consistency.In the error message when a type cannot be resolved:
return reflect.Value{}, fmt.Errorf("can't resolve type %v for %s:\n%s", fullyQualifiedTypeName(in.Type), caller, c.formatResolveStack())According to the Uber Go style guide, contractions should be avoided in error messages. Consider rephrasing as:
-return reflect.Value{}, fmt.Errorf("can't resolve type %v for %s:\n%s", +return reflect.Value{}, fmt.Errorf("cannot resolve type %v for %s:\n%s",
Line range hint
470-471: Avoid contractions in error messages for clarity.In the error message:
return []reflect.Value{}, fmt.Errorf("depinject.Out struct %s on package can't have unexported field", values[i].String())The contraction "can't" should be avoided. Rephrase the message as:
-return []reflect.Value{}, fmt.Errorf("depinject.Out struct %s on package can't have unexported field", values[i].String()) +return []reflect.Value{}, fmt.Errorf("depinject.Out struct %s on package cannot have unexported field", values[i].String())
