Ondrej Kokes 2e30f1231b docs: textparse.Parser return type mismatch 
The docs suggest the Next method returns a bool, but that's not the case (`Entry` is an int).

```
	// Next advances the parser to the next sample. It returns false if no
	// more samples were read or an error occurred.
	Next() (Entry, error)
```

The docs were first added in d80a3de235 in 2017. Back then the signature was
indeed `func (p *Parser) Next() bool`. But then it got refactored in 76a4a46cb0
and the signature changed with it, yet docs stayed the same - and eventually made their way into the `Parser` interface.

However, the Protobuf parser does have the right wording: 5de2df752f

```
// Next advances the parser to the next "sample" (emulating the behavior of a
// text format parser). It returns (EntryInvalid, io.EOF) if no samples were
// read.
```

Changing all other implementations (and the interface itself) to match this doc.

Łukasz Mierzwa 5597020a60 Use github.com/klauspost/compress for gzip and zlib 
klauspost/compress is a high quality drop-in replacement for common Go
compression libraries. Since Prometheus sends out a lot of HTTP requests
that often return compressed output having improved compression
libraries helps to save cpu & memory resources.
On a test Prometheus server I was able to see cpu reduction from 31 to
30 cores.

UTF-8: Add partial support for parsing UTF-8 metric and label names
 2024-02-16 11:42:55 +01:00
Owen Williams a28d7865ad UTF-8: Add support for parsing UTF8 metric and label names 
This adds support for the new grammar of `{"metric_name", "l1"="val"}` to promql and some of the exposition formats.
This grammar will also be valid for non-UTF-8 names.
UTF-8 names will not be considered valid unless model.NameValidationScheme is changed.

This does not update the go expfmt parser in text_parse.go, which will be addressed by https://github.com/prometheus/common/issues/554/.
