### Consistency Guarantees

MinIO follows strict **read-after-write** and **list-after-write** consistency model for all i/o operations both in distributed and standalone modes. This consistency model is only guaranteed if you use disk filesystems such as xfs, zfs or btrfs etc.. for distributed setup.

	stringToSign := getStringToSignV2(method, encodedResource, encodedQuery, headers, "")
	signature := calculateSignatureV2(stringToSign, cred.SecretKey)
	return signature
}

// compareSignatureV2 returns true if and only if both signatures
// are equal. The signatures are expected to be base64 encoded strings
// according to the AWS S3 signature V2 spec.
func compareSignatureV2(sig1, sig2 string) bool {

Until we can provide the same guarantees for core plugins, we need to be more conservative for existing classes and not follow best practices. This means conventions need to be set in both a plugin and the constructor. This keeps existing builds working, but it may complicate the implementation.

This is preferred for entirely new things:

```groovy
public interface NewThing {

// - sf.LowerBound < sz, when sf.LowerBound alone is specified
// - sz < sf.UpperBound, when sf.UpperBound alone is specified
// - sf.LowerBound < sz < sf.UpperBound when both are specified,
func (sf BatchJobSizeFilter) InRange(sz int64) bool {
	if sf.UpperBound > 0 && sz > int64(sf.UpperBound) {
		return false
	}

	if sf.LowerBound > 0 && sz < int64(sf.LowerBound) {
		return false

      visit(t.getUpperBounds());
    }

    private void map(TypeVariableKey var, Type arg) {
      if (mappings.containsKey(var)) {
        // Mapping already established
        // This is possible when following both superClass -> enclosingClass
        // and enclosingclass -> superClass paths.
        // Since we follow the path of superclass first, enclosing second,
        // superclass mapping should take precedence.
        return;

/// tip

This last path operation will have the combination of tags: `["items", "custom"]`.

And it will also have both responses in the documentation, one for `404` and one for `403`.

Now, let's see the module at `app/main.py`.
