If you are not getting cache hits from the build cache, you may be using the wrong version of Java. A fixed version (Java 11) is required to get remote cache hits.

### Building a distribution from source

To create a Gradle distribution from the source tree you can run either of the following:

	"time"

	"github.com/rcrowley/go-metrics"
)

//go:generate msgp -file $GOFILE

const (
	// beta is the weight used to calculate exponential moving average
	beta = 0.1 // Number of averages considered = 1/(1-beta)
)

// rateMeasurement captures the transfer details for one bucket/target
//msgp:ignore rateMeasurement

type rateMeasurement struct {
	lock                 sync.Mutex

```Python hl_lines="10"
{!../../docs_src/query_params_str_validations/tutorial003.py!}
```

## 添加正则表达式

你可以定义一个参数值必须匹配的<abbr title="正则表达式或正则是定义字符串搜索模式的字符序列。">正则表达式</abbr>：

```Python hl_lines="11"
{!../../docs_src/query_params_str_validations/tutorial004.py!}
```

这个指定的正则表达式通过以下规则检查接收到的参数值：

* `^`：以该符号之后的字符开头，符号之前没有字符。
* `fixedquery`: 值精确地等于 `fixedquery`。
* `$`: 到此结束，在 `fixedquery` 之后没有更多字符。

// It is equivalent to SplitAfterN with a count of -1.
func SplitAfter(s, sep []byte) [][]byte {
	return genSplit(s, sep, len(sep), -1)
}

var asciiSpace = [256]uint8{'\t': 1, '\n': 1, '\v': 1, '\f': 1, '\r': 1, ' ': 1}

// Fields interprets s as a sequence of UTF-8-encoded code points.
// It splits the slice s around each instance of one or more consecutive white space

 * example, the Unicode trademark sign (™) could be confused for the letters "TM" in
