After testing several alternatives, I decided that I was going to use <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">**Pydantic**</a> for its advantages.

Then I contributed to it, to make it fully compliant with JSON Schema, to support different ways to define constraint declarations, and to improve editor support (type checks, autocompletion) based on the tests in several editors.

    This is something that you have to do yourself in your code, and make sure you use those JSON keys.

    It's almost the only thing that you have to remember to do correctly yourself, to be compliant with the specifications.

    For the rest, **FastAPI** handles it for you.

## Update the dependencies

Now we are going to update our dependencies.

## Goals

Ztunnel should:
* **Not break users**. This means that deploying Ztunnel should retain all existing Kubernetes behavior.
  * This includes UDP, non-compliant HTTP, server-first protocols, stateful sets, external services, etc.
  * Explicitly opting into behavioral changes can be acceptable. For example, introducing Istio multi-cluster semantics.

		"Don't complain about un-parseable input documents, for cases where analyze should run only on k8s compliant inputs.")
	analysisCmd.PersistentFlags().StringVarP(&revisionSpecified, "revision", "", "default",
		"analyze a specific revision deployed.")
	return analysisCmd

	// For GNU PAX sparse format 0.0 support.
	// This function transforms the sparse format 0.0 headers into format 0.1
	// headers since 0.0 headers were not PAX compliant.
	var sparseMap []string

	paxHdrs := make(map[string]string)
	for len(sbuf) > 0 {
		key, value, residual, err := parsePAXRecord(sbuf)

			return nil, ErrHeader
		}
		sbuf = residual

// objects are slightly larger due to encryption overhead.
// Further, it decrypts all single-part SSE-S3 encrypted objects
// and formats ETags of SSE-C / SSE-KMS encrypted objects to
// be AWS S3 compliant.
//
// DecryptETags uses a KMS bulk decryption API, if available, which
// is more efficient than decrypting ETags sequentually.
func DecryptETags(ctx context.Context, k kms.KMS, objects []ObjectInfo) error {

	PAXRecords map[string]string

	// Format specifies the format of the tar header.
	//
	// This is set by Reader.Next as a best-effort guess at the format.
	// Since the Reader liberally reads some non-compliant files,
	// it is possible for this to be FormatUnknown.
	//
	// If the format is unspecified when Writer.WriteHeader is called,
	// then it uses the first format (in the order of USTAR, PAX, GNU)

     Moreover, Your grants from a particular Contributor are reinstated on an
     ongoing basis if such Contributor notifies You of the non-compliance by
     some reasonable means, this is the first time You have received notice of
     non-compliance with this License from such Contributor, and You become
     compliant prior to 30 days after Your receipt of the notice.
