## 2. Enable bucket lifecycle configuration

- Create a bucket lifecycle configuration which expires the objects under the prefix `old/` on `2020-01-01T00:00:00.000Z` date and the objects under `temp/` after 7 days.
- Enable bucket lifecycle configuration using `mc`:

```sh
$ mc ilm import play/testbucket <<EOF
{
    "Rules": [
        {

		m = Count(s, old)
	}
	if m == 0 {
		// Just return a copy.
		return append([]byte(nil), s...)
	}
	if n < 0 || m < n {
		n = m
	}

	// Apply replacements to buffer.
	t := make([]byte, len(s)+n*(len(new)-len(old)))
	w := 0
	start := 0
	if len(old) > 0 {
		for range n {
			j := start + Index(s[start:], old)
			w += copy(t[w:], s[start:j])
			w += copy(t[w:], new)

	}
}

func Test386EndToEnd(t *testing.T) {
	testEndToEnd(t, "386", "386")
}

func TestARMEndToEnd(t *testing.T) {
	defer func(old int) { buildcfg.GOARM.Version = old }(buildcfg.GOARM.Version)
	for _, goarm := range []int{5, 6, 7} {
		t.Logf("GOARM=%d", goarm)
		buildcfg.GOARM.Version = goarm
		testEndToEnd(t, "arm", "arm")
		if goarm == 6 {

	for _, tt := range ReplaceTests {
		var (
			in  = []byte(tt.in)
			old = []byte(tt.old)
			new = []byte(tt.new)
		)
		if !asan.Enabled {
			allocs := testing.AllocsPerRun(10, func() { Replace(in, old, new, tt.n) })
			if allocs > 1 {
				t.Errorf("Replace(%q, %q, %q, %d) allocates %.2f objects", tt.in, tt.old, tt.new, tt.n, allocs)
			}
		}
		in = append(in, "<spare>"...)
