Go Code Review & Diagnostics Lab

Inspects Go code using deterministic rules (GO-SEC-001..004, GO-DB-001..002, GO-CONC-001, GO-ERR-001, GO-PERF-001) and local go vet / gofmt when running on your host. Distinguishes confirmed diagnostics, potential issues, and educational heuristics.

Go Source Snippet to Analyze:

package user

import (
	"database/sql"
	"fmt"
	"io"
	"net/http"
	_ "net/http/pprof"
	"regexp"
)

func HandleLookup(w http.ResponseWriter, r *http.Request, db *sql.DB) {
	body, _ := io.ReadAll(r.Body)
	re := regexp.MustCompile(`^[a-z0-9]+$`)
	if !re.Match(body) {
		panic("invalid body")
	}
	q := fmt.Sprintf("SELECT email FROM users WHERE id = '%s'", string(body))
	rows, err := db.Query(q)
	if err != nil {
		panic(err)
	}
	go func() {
		http.Get("http://audit.internal/log")
	}()
	_ = rows
}
