## Small ConcreteFunction Example

The following example loads a saved model from `"/path/to/model"` and
executes a function `f` taking no arguments and returning one single
value (error checking is omitted for simplicity):

```c
TF_Status* status = TF_NewStatus();
TFE_ContextOptions* ctx_options = TFE_NewContextOptions();
TFE_Context* ctx = TFE_NewContext(ctx_options, status);

		PRUNTIME_FUNCTION FunctionEntry;
		ULONG64 ImageBase;
		VOID *HandlerData;
		ULONG64 EstablisherFrame;

		FunctionEntry = RtlLookupFunctionEntry(ControlPc, &ImageBase, NULL);

		if (!FunctionEntry) {
			// For simplicity, don't unwind leaf entries, which are not used in this test.
			break;
		} else {
			RtlVirtualUnwind(0, ImageBase, ControlPc, FunctionEntry, &context, &HandlerData, &EstablisherFrame, NULL);
		}

## Context

In Gradle we often need to serialize in-memory objects for caching, or to transmit them across process barriers, etc.
Java serialization is one way to implement this, however, despite its simplicity of implementation, it has several drawbacks:

- **Performance:**
Java's built-in serialization mechanism is often slower compared to other serialization solutions.

```

!!! tip
    You could reduce duplication in that code by putting it in a function and using it from both `database.py` and `tests/test_sql_app.py`.

    For simplicity and to focus on the specific testing code, we are just copying it.

## Create the database

Because now we are going to use a new database in a new file, we need to make sure we create the database with:

```Python

package pkgpath

import (
	"internal/testenv"
	"os"
	"testing"
)

const testEnvName = "GO_PKGPATH_TEST_COMPILER"

// This init function supports TestToSymbolFunc. For simplicity,
// we use the test binary itself as a sample gccgo driver.
// We set an environment variable to specify how it should behave.
func init() {
	switch os.Getenv(testEnvName) {
	case "":
		return
	case "v1":

			//   got = √x + k
			// for some k such that |k| < 2**(-p). Thus,
			//   got² = (√x + k)² = x + 2k√n + k²
			// and the error must satisfy
			//   err = |got² - x| ≈ | 2k√n | < 2**(-p+1)*√n
			// Ignoring the k² term for simplicity.

			// err = |got² - x|
			// (but do intermediate steps with 32 guard digits to
			// avoid introducing spurious rounding-related errors)
			sq := new(Float).SetPrec(prec+32).Mul(got, got)

	io.WriteString(os.Stdout, s) // Ignoring error for simplicity.

	// Output:
	// Kim is 22 years old.
}

func ExampleSprintln() {
	const name, age = "Kim", 22
	s := fmt.Sprintln(name, "is", age, "years old.")

	io.WriteString(os.Stdout, s) // Ignoring error for simplicity.

	// Output:
	// Kim is 22 years old.
}

func ExampleSprintf() {

func (c Topology) StableName() string {
	var prefix string
	// If its a known cluster name, use that directly.
	// This will not be dynamic, and allows 1:1 correlation of cluster name and test name for simplicity.
	if _, f := knownClusterNames[c.Name()]; f {
		return c.Name()
	}
	if c.IsPrimary() {
		if c.IsConfig() {
			prefix = "primary"
		} else {
			prefix = "externalistiod"
		}

// if it doesn't exist. This allows users to manage it through other means or modify it as they wish.
// If it is deleted, however, it will be added back.
// This controller intentionally does not do leader election for simplicity. Because we only create
// and not update there is no need; the first controller to create the GatewayClass wins.
type ClassController struct {
	queue   controllers.Queue
	classes kclient.Client[*gateway.GatewayClass]
}

/**
 * Since Gradle creates a high volume of progress events, this serializer trades simplicity
 * for the smallest possible serialized form. It uses a single byte indicating the presence of optional
 * fields instead of writing an "absent" byte for each of them like most of our serializers do.
