• The extractSection function does not handle cases where the start or end strings are not found properly. It might return incorrect results.

func extractSection(s string, start, end string) (prefix, body, suffix string, found bool) {

internal/mkcgo/parse.go:137

• The newFn function has a lot of string manipulation which could be error-prone. Ensure that it handles edge cases properly.

func newFn(s string, opts fnOptions) (*fn, error) {

internal/mkcgo/mkcgo.go:62

• Handle the case where fileName is empty to avoid unexpected behavior.

err = os.WriteFile(*fileName, data, 0644)

internal/mkcgo/mkcgo.go:64

• Ensure fileName ends with .go before using TrimSuffix to avoid incorrect file naming.

cfileName := strings.TrimSuffix(*fileName, ".go") + ".c"

internal/mkcgo/mkcgo.go:132

• [nitpick] Simplify the error handling for better readability.

if closeErr := f.Close(); err == nil { err = closeErr }

internal/mkcgo/generate.go:244

• The function libArgList in the param struct returns a slice with a single string element, which is unnecessary. It should return a string directly.

return []string{s}

dsa.go:58

• The function signature for withKey has been changed from func(C.GO_EVP_PKEY_PTR) C.int to func(ossl.EVP_PKEY_PTR) error. Ensure that the functions passed to withKey are updated to handle errors correctly.

func (k *PrivateKeyDSA) withKey(f func(ossl.EVP_PKEY_PTR) error) error {

ecdsa_test.go:25

• The removal of t.Parallel() should be justified. If there were no issues with parallel execution, consider adding it back to improve test performance.

t.Parallel()
