How can a race condition be identified in a system?

The Race Condition can be identified by the following methods:

• Static code analysis — searching for potentially unsafe operations with shared resources.
• Dynamic testing with high concurrency — running multiple goroutines or threads that access shared data simultaneously.
• Using tools for race detection — Go has a built-in race detector, which is run with the -race flag:

 go run -race main.go

It helps identify places where concurrent access to memory occurs without proper synchronization.

• Logging and monitoring — analyzing unstable behavior and errors that may indicate races.

Example of using the race detector:

package main
import (
    "fmt"
    "sync"
)

func main() {
    var wg sync.WaitGroup
    counter := 0
    wg.Add(2)
    go func() {
        defer wg.Done()
        counter++ // potential race
    }()
    go func() {
        defer wg.Done()
        counter++ // potential race
    }()
    wg.Wait()
    fmt.Println(counter)
}

Running with -race will detect a race on the counter variable.
