## `fastapi dev`

Quando você roda `fastapi dev`, isso vai executar em modo de desenvolvimento.

Por padrão, teremos o **recarregamento automático** ativo, então o programa irá recarregar o servidor automaticamente toda vez que você fizer mudanças no seu código. Isso usa muitos recursos e pode ser menos estável. Você deve apenas usá-lo em modo de desenvolvimento.

CL 568340 - fixed a spurious race in time.Ticker.Reset (added via accepted proposal https://go.dev/issue/33184), doesn't seem to need a release note
CL 562619 - x/website CL documented minimum bootstrap version on go.dev, mentioning accepted proposals go.dev/issue/54265 and go.dev/issue/44505; doesn't need a release note

## Ports {#ports}

### Darwin {#darwin}

<!-- go.dev/issue/64207 -->
As [announced](go1.22#darwin) in the Go 1.22 release notes,
Go 1.23 requires macOS 11 Big Sur or later;
support for previous versions has been discontinued.

### Linux {#linux}

<!-- go.dev/issue/67001 -->

In Go 1.23, overhead should be in the single digit percentages.

<!-- https://go.dev/issue/62737 , https://golang.org/cl/576681,  https://golang.org/cl/577615 -->
The compiler in Go 1.23 can now overlap the stack frame slots of local variables
accessed in disjoint regions of a function, which reduces stack usage
for Go applications.

<!-- https://go.dev/cl/577935 -->
For 386 and amd64, the compiler will use information from PGO to align certain

## Changes to the language {#language}

<!-- go.dev/issue/61405, CL 557835, CL 584596 -->
Go 1.23 makes the (Go 1.22) ["range-over-func" experiment](/wiki/RangefuncExperiment) a part of the language.
The "range" clause in a "for-range" loop now accepts iterator functions of the following types

	func(func() bool)
	func(func(K) bool)
	func(func(K, V) bool)

as range expressions.

	@echo "Running tests for IAM (external IDP, etcd backends)"
	@MINIO_API_REQUESTS_MAX=10000 CGO_ENABLED=0 go test -tags kqueue,dev -v -run TestIAM* ./cmd
	@echo "Running tests for IAM (external IDP, etcd backends) with -race"
	@MINIO_API_REQUESTS_MAX=10000 GORACE=history_size=7 CGO_ENABLED=1 go test -race -tags kqueue,dev -v -run TestIAM* ./cmd

test-iam-ldap-upgrade-import: install-race ## verify IAM (external LDAP IDP)

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

<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

# Note that here we want the latest version that matches TF major.minor version
# Note that we must use nightly here as these are used in nightly jobs
# For release jobs, we will pin these on the release branch
