Pull Request Overview
This PR refactors the internal DI implementation by renaming packages, consolidating APIs under a new global package, and enhancing error handling, logging, and performance measurement. It also updates module requirements and adds linting support.
- Renamed
dix_internal
todixinternal
and introduceddixglobal
for simplified DI usage - Refactored provider/inject internals (
providerFn
,getOutputTypeValues
, cycle detection) with improved logging and timing - Updated Go work setup, module dependencies, Makefile lint target, and CI lint action

- [nitpick] The example refers to
di.New()
but this package isdixglobal
; update the comment to usedixglobal.New()
for clarity.
// c := di.New()
dixinternal/cycle-check.go:8
- [nitpick] The new cycle detection logic in
isCycle
lacks unit tests; consider adding tests to verify detection and error reporting of circular dependencies.
func (x *Dix) isCycle() (string, bool) {
dixinternal/dix.go:27
- Options has no Check method declared; this call will fail to compile. Consider defining a Check() method on Options or removing this call.

🛠️ Refactor suggestion
Consider making cycle detection less aggressive.
The cycle detection logic is well-implemented with structured logging, but using assert.Must
will cause the application to panic/exit on any circular dependency. Consider returning an error instead to allow applications to handle cycles gracefully.
func (x *Dix) Inject(param any, opts ...Option) any {
if dep, ok := x.isCycle(); ok {
logger.Error().
Str("cycle_path", dep).
Str("component", reflect.TypeOf(param).String()).

In dixinternal/api.go around lines 19 to 30, the cycle detection currently uses
assert.Must which panics on detecting a circular dependency. Modify the Inject
method to return an error instead of panicking, so that the caller can handle
the circular dependency gracefully. Change the function signature to return
(any, error), replace assert.Must calls with error returns, and propagate errors
from the inject call accordingly.

Critical: Injection errors are silently ignored
The Inject
function discards errors returned by _dix.Inject()
. This could hide important runtime errors such as missing dependencies or cyclic dependencies.
Consider either:
- Propagating the error by changing the signature to
Inject[T any](data T, opts ...dixinternal.Option) (T, error)
- Panicking on error to maintain the current API while ensuring errors are visible
func Inject[T any](data T, opts ...dixinternal.Option) T {
vp := reflect.ValueOf(data)
+ var err error
if vp.Kind() == reflect.Struct {
- _ = _dix.Inject(&data, opts...)
+ err = _dix.Inject(&data, opts...)
} else {
- _ = _dix.Inject(data, opts...)
+ err = _dix.Inject(data, opts...)
}
+ if err != nil {
+ panic(err)
+ }
return data
}

In dixglobal/global.go around lines 31 to 39, the Inject function ignores errors
returned by _dix.Inject, which can hide critical runtime issues. Modify the
function signature to return both the injected data and an error, then capture
and return the error from _dix.Inject instead of discarding it. Update all call
sites accordingly to handle the error, ensuring injection failures are properly
reported and not silently ignored.

: Enhanced logging and timing measurement improve observability.The addition of detailed provider execution logging with timing information and stack traces will greatly help with debugging dependency injection issues.
100-107
: Provider error handling enhancement is well implemented.The new error detection and panic behavior for provider functions that return errors provides much better error reporting with stack trace context.
268-275
: Error handling for injected functions is well implemented.The validation and handling of error return values from injected functions provides good error propagation with proper context wrapping.
309-316
: Inject method improvement from panic to error return is excellent.Changing the
inject
method to return an error instead of panicking makes the API much more user-friendly and allows for better error handling by callers.

: Provider function validation enhancement improves type safety.The strict validation of provider function signatures, especially the requirement that the second return value must be an error type, provides better type safety and clearer API contracts.

: Provider registration validation is comprehensive and well-designed.The enhanced validation for provider functions, including checks for variadic functions, output count limits, and proper signature validation, significantly improves the robustness of the dependency injection system.

Function injection validation is overly strict and may break existing code.
The new validation requires injectable functions to either have no return value or return only an error type. This is a significant breaking change that may not be backward compatible.
Consider making this validation configurable or providing a migration path:
+func (x *Dix) injectFunc(vp reflect.Value, opt Options) {
+ // Allow legacy behavior through options
+ if !opt.StrictFunctionValidation {
+ // Original less strict validation
+ assert.If(vp.Type().NumOut() > 2, "func output num should <=2")
+ assert.If(vp.Type().NumIn() == 0, "func input num should not be zero")
+ // ... rest of original logic
+ return
+ }
+
+ // Strict validation for new code
assert.If(vp.Type().NumOut() > 1, "func output num should <=1")

In dixinternal/dix.go around lines 225 to 239, the current validation enforces
that injectable functions must have zero or one return value and if one, it must
be an error type, which is too restrictive and breaks backward compatibility.
Modify the validation to either make this check optional via a configuration
flag in Options or relax the constraint to allow other return types, ensuring
existing code continues to work. Provide a clear way to opt-in to strict
validation or a migration path for users to adapt.

In dixinternal/provider.go around lines 21 to 34, the Validate method
redundantly checks the same type condition three times with identical logic.
Simplify this by consolidating the repeated isMap, isList, and default checks
into a single type validation check that covers all cases, removing duplicate
calls to isMapListSupportedType and redundant error returns.

: Simplify redundant validation logic.The validation method performs the same type check three times with identical conditions. This can be simplified to a single check.
func (v providerInputType) Validate() error { - if v.isMap && !isMapListSupportedType(v.typ) { - return errors.Errorf("input map value type kind not support, kind=%s", v.typ.Kind().String()) - } - - if v.isList && !isMapListSupportedType(v.typ) { - return errors.Errorf("input list element value type kind not support, kind=%s", v.typ.Kind().String()) - } - - if !isMapListSupportedType(v.typ) { - return errors.Errorf("input value type kind not support, kind=%s", v.typ.Kind().String()) - } - - return nil + if !isMapListSupportedType(v.typ) { + context := "input value" + if v.isMap { + context = "input map value" + } else if v.isList { + context = "input list element value" + } + return errors.Errorf("%s type kind not support, kind=%s", context, v.typ.Kind().String()) + } + return nil }dixinternal/dix.go (2)

: Type kind validation is overly restrictive.The assertion only allows
ptr
,interface
, andfunc
kinds, but the error message and later code suggeststruct
should also be supported. This will cause runtime errors for valid struct types.switch outTyp.Kind() { - case reflect.Ptr, reflect.Interface, reflect.Func: + case reflect.Ptr, reflect.Interface, reflect.Func, reflect.Struct: default: - return r.WithErrorf("provider type kind error, the supported type kinds are <ptr,interface,func>, type=%s kind=%s", outTyp, outTyp.Kind()) + return r.WithErrorf("provider type kind error, the supported type kinds are <ptr,interface,func,struct>, type=%s kind=%s", outTyp, outTyp.Kind()) }
232-246
: Function injection validation is overly strict and may break existing code.The new validation requires injectable functions to either have no return value or return only an error type. This is a significant breaking change that may not be backward compatible.
Consider making this validation configurable through options:
func (x *Dix) injectFunc(vp reflect.Value, opt Options) (r result.Error) { defer result.RecoveryErr(&r) + // Allow legacy behavior through options + if !opt.StrictFunctionValidation { + // Original validation for backward compatibility + if vp.Type().NumOut() > 2 { + return result.ErrorOf("func output num should <=2") + } + if vp.Type().NumIn() == 0 { + return result.ErrorOf("func input num should not be zero") + } + // Continue with original injection logic... + } + assert.If(vp.Type().NumOut() > 1, "func output num should <=1") assert.If(vp.Type().NumIn() == 0, "func input num should not be zero")Also add
StrictFunctionValidation bool
field to theOptions
struct inoption.go

In dixinternal/dix.go around lines 482 to 484, the assertion message on line 484
incorrectly states "the func of provider output num should >= two" while the
condition checks if the number of outputs is greater than 2. Update the
assertion message to correctly reflect the condition, such as "the func of
provider output num should be <= 2" or a message consistent with the condition
typ.NumOut() > 2.
- Update error handling in dixinternal/dix.go to use errors.WrapErr instead of errors.NewErr - Upgrade github.com/pubgo/funk dependency to v0.5.66-alpha.3 in go.mod files
- Rename error variable to 'r' for consistency- Use CatchErr() method to handle errors from injectFunc calls - Refactor error creation using WrapErr() for better error context - Remove commented-out debug code

: Type validation logic is correct by design.The validation restricts provider output types to pointer, interface, and function types, while struct types are handled differently via direct instantiation in the
getValue
method. This design separation is appropriate.
155-159
: Struct handling logic is well-designed.The direct instantiation of struct types with dependency injection is a clean approach that avoids the complexity of provider registration for structs.
289-329
: Struct injection logic is well-implemented.The method correctly handles various field types including nested structs, with proper error handling and type checking.
366-375
: Injection method prefix pattern is well-implemented.The ability to inject dependencies into methods with a specific prefix (
DixInject
) provides a clean API for method-based dependency injection.

In dixinternal/dix.go at line 438, the current use of log.Error to report
incorrect output types may obscure programming errors. Replace the log.Error
