# xxhash
[![GoDoc](https://godoc.org/github.com/cespare/xxhash?status.svg)](https://godoc.org/github.com/cespare/xxhash)
[![Build Status](https://travis-ci.org/cespare/xxhash.svg?branch=master)](https://travis-ci.org/cespare/xxhash)
xxhash is a Go implementation of the 64-bit
[xxHash](http://cyan4973.github.io/xxHash/) algorithm, XXH64. This is a
high-quality hashing algorithm that is much faster than anything in the Go
standard library.
This package provides a straightforward API:
```
func Sum64(b []byte) uint64
func Sum64String(s string) uint64
type Digest struct{ ... }
func New() *Digest
```
The `Digest` type implements hash.Hash64. Its key methods are:
```
func (*Digest) Write([]byte) (int, error)
func (*Digest) WriteString(string) (int, error)
func (*Digest) Sum64() uint64
```
This implementation provides a fast pure-Go implementation and an even faster
assembly implementation for amd64.
## Compatibility
This package is in a module and the latest code is in version 2 of the module.
You need a version of Go with at least "minimal module compatibility" to use
github.com/cespare/xxhash/v2:
* 1.9.7+ for Go 1.9
* 1.10.3+ for Go 1.10
* Go 1.11 or later
I recommend using the latest release of Go.
## Benchmarks
Here are some quick benchmarks comparing the pure-Go and assembly
implementations of Sum64.
| input size | purego | asm |
| --- | --- | --- |
| 5 B | 979.66 MB/s | 1291.17 MB/s |
| 100 B | 7475.26 MB/s | 7973.40 MB/s |
| 4 KB | 17573.46 MB/s | 17602.65 MB/s |
| 10 MB | 17131.46 MB/s | 17142.16 MB/s |
These numbers were generated on Ubuntu 18.04 with an Intel i7-8700K CPU using
the following commands under Go 1.11.2:
```
$ go test -tags purego -benchtime 10s -bench '/xxhash,direct,bytes'
$ go test -benchtime 10s -bench '/xxhash,direct,bytes'
```

// MetricFamilyToOpenMetrics converts a MetricFamily proto message into the
// OpenMetrics text format and writes the resulting lines to 'out'. It returns
// the number of bytes written and any error encountered. The output will have
// the same order as the input, no further sorting is performed. Furthermore,
// this function assumes the input is already sanitized and does not perform any
// sanity checks. If the input contains duplicate metrics or invalid metric or
// label names, the conversion will result in invalid text format output.
//
// This function fulfills the type 'expfmt.encoder'.
//
// Note that OpenMetrics requires a final `# EOF` line. Since this function acts
// on individual metric families, it is the responsibility of the caller to
// append this line to 'out' once all metric families have been written.
// Conveniently, this can be done by calling FinalizeOpenMetrics.
//
// The output should be fully OpenMetrics compliant. However, there are a few
// missing features and peculiarities to avoid complications when switching from
// Prometheus to OpenMetrics or vice versa:
//
// - Counters are expected to have the `_total` suffix in their metric name. In
// the output, the suffix will be truncated from the `# TYPE` and `# HELP`
// line. A counter with a missing `_total` suffix is not an error. However,
// its type will be set to `unknown` in that case to avoid invalid OpenMetrics
// output.
//
// - No support for the following (optional) features: `# UNIT` line, `_created`
// line, info type, stateset type, gaugehistogram type.
//
// - The size of exemplar labels is not checked (i.e. it's possible to create
// exemplars that are larger than allowed by the OpenMetrics specification).
//
// - The value of Counters is not checked. (OpenMetrics doesn't allow counters
// with a `NaN` value.)

* If you have a trivial fix or improvement, go ahead and create a pull request,
addressing (with `@...`) the maintainer of this repository (see
addressing (with `@...`) a suitable maintainer of this repository (see
[MAINTAINERS.md](MAINTAINERS.md)) in the description of the pull request.
* If you plan to do something more involved, first discuss your ideas
on our [mailing list](https://groups.google.com/forum/?fromgroups#!forum/prometheus-developers).
This will avoid unnecessary work and surely give you and us a good deal
of inspiration.
of inspiration. Also please see our [non-goals issue](https://github.com/prometheus/docs/issues/149) on areas that the Prometheus community doesn't plan to work on.
* Relevant coding style guidelines are the [Go Code Review
Comments](https://code.google.com/p/go-wiki/wiki/CodeReviewComments)
and the _Formatting and style_ section of Peter Bourgon's [Go: Best
Practices for Production

* Be sure to sign off on the [DCO](https://github.com/probot/dco#how-it-works)
## Steps to Contribute
Should you wish to work on an issue, please claim it first by commenting on the GitHub issue that you want to work on it. This is to prevent duplicated efforts from contributors on the same issue.
Please check the [`help-wanted`](https://github.com/prometheus/procfs/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22) label to find issues that are good for getting started. If you have questions about one of the issues, with or without the tag, please comment on them and one of the maintainers will clarify it. For a quicker response, contact us over [IRC](https://prometheus.io/community).
For quickly compiling and testing your changes do:
```
make test # Make sure all the tests pass before you commit and push :)
```
We use [`golangci-lint`](https://github.com/golangci/golangci-lint) for linting the code. If it reports an issue and you think that the warning needs to be disregarded or is a false-positive, you can add a special comment `//nolint:linter1[,linter2,...]` before the offending line. Use this sparingly though, fixing the code to comply with the linter's recommendation is in general the preferred course of action.
## Pull Request Checklist
* Branch from the master branch and, if needed, rebase to the current master branch before submitting your pull request. If it doesn't merge cleanly with master you may be asked to rebase your changes.
* Commits should be as small as possible, while ensuring that each commit is correct independently (i.e., each commit should compile and pass tests).
* If your patch is not getting reviewed or you need a specific person to review it, you can @-reply a reviewer asking for a review in the pull request or a comment, or you can ask for a review on IRC channel [#prometheus](https://webchat.freenode.net/?channels=#prometheus) on irc.freenode.net (for the easiest start, [join via Riot](https://riot.im/app/#/room/#prometheus:matrix.org)).
* Add tests relevant to the fixed bug or new feature.
## Dependency management
The Prometheus project uses [Go modules](https://golang.org/cmd/go/#hdr-Modules__module_versions__and_more) to manage dependencies on external packages. This requires a working Go environment with version 1.12 or greater installed.
All dependencies are vendored in the `vendor/` directory.
To add or update a new dependency, use the `go get` command:
```bash
# Pick the latest tagged release.
go get example.com/some/module/pkg
# Pick a specific version.
go get example.com/some/module/pkg@vX.Y.Z
```
Tidy up the `go.mod` and `go.sum` files and copy the new/updated dependency to the `vendor/` directory:
```bash
# The GO111MODULE variable can be omitted when the code isn't located in GOPATH.
GO111MODULE=on go mod tidy
GO111MODULE=on go mod vendor
```
You have to commit the changes to `go.mod`, `go.sum` and the `vendor/` directory before submitting the pull request.
## API Implementation Guidelines
### Naming and Documentation
Public functions and structs should normally be named according to the file(s) being read and parsed. For example,
the `fs.BuddyInfo()` function reads the file `/proc/buddyinfo`. In addition, the godoc for each public function
should contain the path to the file(s) being read and a URL of the linux kernel documentation describing the file(s).
### Reading vs. Parsing
Most functionality in this library consists of reading files and then parsing the text into structured data. In most
cases reading and parsing should be separated into different functions/methods with a public `fs.Thing()` method and
a private `parseThing(r Reader)` function. This provides a logical separation and allows parsing to be tested
directly without the need to read from the filesystem. Using a `Reader` argument is preferred over other data types
such as `string` or `*File` because it provides the most flexibility regarding the data source. When a set of files
in a directory needs to be parsed, then a `path` string parameter to the parse function can be used instead.
### /proc and /sys filesystem I/O
The `proc` and `sys` filesystems are pseudo file systems and work a bit differently from standard disk I/O.
Many of the files are changing continuously and the data being read can in some cases change between subsequent
reads in the same file. Also, most of the files are relatively small (less than a few KBs), and system calls
to the `stat` function will often return the wrong size. Therefore, for most files it's recommended to read the
full file in a single operation using an internal utility function called `util.ReadFileNoStat`.
This function is similar to `ioutil.ReadFile`, but it avoids the system call to `stat` to get the current size of
the file.
Note that parsing the file's contents can still be performed one line at a time. This is done by first reading
the full file, and then using a scanner on the `[]byte` or `string` containing the data.
```
data, err := util.ReadFileNoStat("/proc/cpuinfo")
if err != nil {
return err
}
reader := bytes.NewReader(data)
scanner := bufio.NewScanner(reader)
```
The `/sys` filesystem contains many very small files which contain only a single numeric or text value. These files
can be read using an internal function called `util.SysReadFile` which is similar to `ioutil.ReadFile` but does
not bother to check the size of the file before reading.
```
data, err := util.SysReadFile("/sys/class/power_supply/BAT0/capacity")
```

## Usage
The procfs library is organized by packages based on whether the gathered data is coming from
/proc, /sys, or both. Each package contains an `FS` type which represents the path to either /proc, /sys, or both. For example, current cpu statistics are gathered from
/proc, /sys, or both. Each package contains an `FS` type which represents the path to either /proc,

## Package Organization
The packages in this project are organized according to (1) whether the data comes from the `/proc` or
`/sys` filesystem and (2) the type of information being retrieved. For example, most process information
can be gathered from the functions in the root `procfs` package. Information about block devices such as disk drives
is available in the `blockdevices` sub-package.
## Building and Testing
The procfs library is normally built as part of another application. However, when making
changes to the library, the `make test` command can be used to run the API test suite.
The procfs library is intended to be built as part of another application, so there are no distributable binaries.
However, most of the API includes unit tests which can be run with `make test`.

MemFree uint64
// An estimate of how much memory is available for starting
// new applications, without swapping. Calculated from
// MemFree, SReclaimable, the size of the file LRU lists, and
// the low watermarks in each zone. The estimate takes into
// account that the system needs some page cache to function
// well, and that not all reclaimable slab will be
// reclaimable, due to items being in use. The impact of those
// factors will vary from system to system.
MemAvailable uint64

// The CommitLimit is calculated with the following formula:
// CommitLimit = ([total RAM pages] - [total huge TLB pages]) *
// overcommit_ratio / 100 + [total swap pages]
// For example, on a system with 1G of physical RAM and 7G
// of swap with a `vm.overcommit_ratio` of 30 it would
// yield a CommitLimit of 7.3G.
// For more details, see the memory overcommit documentation
// in vm/overcommit-accounting.
CommitLimit uint64
// The amount of memory presently allocated on the system.
// The committed memory is a sum of all of the memory which
// has been allocated by processes, even if it has not been
// "used" by them as of yet. A process which malloc()'s 1G
// of memory, but only touches 300M of it will show up as
// using 1G. This 1G is memory which has been "committed" to
// by the VM and can be used at any time by the allocating
// application. With strict overcommit enabled on the system
// (mode 2 in 'vm.overcommit_memory'),allocations which would
// exceed the CommitLimit (detailed above) will not be permitted.
