Function initServer

caddy/caddy_test.go:28–43

initServer initializes a Caddy test server and waits for it to be ready. After InitServer, it polls the server to handle a race condition on macOS where SO_REUSEPORT can briefly route connections to the old listener being shut down, resulting in "connection reset by peer".

(t *testing.T, tester *caddytest.Tester, config string, format string)

// SO_REUSEPORT can briefly route connections to the old listener being shut down,
// resulting in "connection reset by peer".
func initServer(t *testing.T, tester *caddytest.Tester, config string, format string) {
	t.Helper()
	tester.InitServer(config, format)

	client := &http.Client{Timeout: 1 * time.Second}
	require.Eventually(t, func() bool {
		resp, err := client.Get("http://localhost:" + testPort)
		if err != nil {
			return false
		}

		require.NoError(t, resp.Body.Close())

		return true
	}, 5*time.Second, 100*time.Millisecond, "server failed to become ready")
}
