The "build tree state" holds the state for the entire build definition for a single build execution within a session.

The build tree state is managed by the `BuildTreeState` class.
An instance is created at the start of a build execution and discarded at the end of the execution.

### Build state

The "build state" holds the state for a build within the build definition for a single build execution, and is contained by the build tree state.

* Keep commits discrete. Avoid including multiple unrelated changes in a single commit.
* Keep commits self-contained. Avoid spreading a single change across multiple commits. A single commit should make sense in isolation.

### Testing changes

After making changes, you can test your code in 2 ways:

1. Run tests.

	"github.com/minio/minio/internal/logger"
	"github.com/minio/pkg/v2/sync/errgroup"
)

const (
	// Represents Erasure backend.
	formatBackendErasure = "xl"

	// Represents Erasure backend - single drive
	formatBackendErasureSingle = "xl-single"

	// formatErasureV1.Erasure.Version - version '1'.
	formatErasureVersionV1 = "1"

	// formatErasureV2.Erasure.Version - version '2'.
	formatErasureVersionV2 = "2"

// made generalized, and can be integrated in benchmarks/unit tests/go check suite tests.
type TestErrHandler interface {
	testing.TB
}

const (
	// ErasureSDStr is the string which is used as notation for Single node ObjectLayer in the unit tests.
	ErasureSDStr string = "ErasureSD"

	// ErasureTestStr is the string which is used as notation for Erasure ObjectLayer in the unit tests.
	ErasureTestStr string = "Erasure"

		return false
	}
	if podHasSidecar(pod) {
		// Ztunnel and sidecar for a single pod is currently not supported; opt out.
		return false
	}
	if pod.GetLabels()[constants.DataplaneModeLabel] == constants.DataplaneModeNone {
		// Pod explicitly asked to not have ambient redirection enabled
		return false

	argPatterns []ellipses.ArgPattern
	endpoints   []string   // Endpoints saved from previous GetEndpoints().
	setIndexes  [][]uint64 // All the sets.
}

// Supported set sizes this is used to find the optimal
// single set size.
var setSizes = []uint64{2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16}

// getDivisibleSize - returns a greatest common divisor of
// all the ellipses sizes.

To run your FastAPI app for development, you can use the `fastapi dev` command:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

# There are two use cases here:
# * Building all docker images (generally in CI). In this case we want to build everything at once, so they share work
# * Building a single docker image (generally during dev). In this case we just want to build the single binary alone
BUILD_ALL ?= true
define build-linux
.PHONY: $(TARGET_OUT_LINUX)/$(shell basename $(1))
ifeq ($(BUILD_ALL),true)

DIR:
  DIR points to a directory on a filesystem. When you want to combine
  multiple drives into a single large system, pass one directory per
  filesystem separated by space. You may also use a '...' convention
  to abbreviate the directory arguments. Remote directories in a
  distributed setup are encoded as HTTP(s) URIs.
