# Contributing
Prometheus uses GitHub to manage reviews of pull requests.
* If you are a new contributor see: [Steps to Contribute](#steps-to-contribute)
* If you have a trivial fix or improvement, go ahead and create a pull request,
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. 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
Environments](https://peter.bourgon.org/go-in-production/#formatting-and-style).
* 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")
```

# procfs
This package provides functions to retrieve system, kernel, and process
metrics from the pseudo-filesystems /proc and /sys.
*WARNING*: This package is a work in progress. Its API may still break in
backwards-incompatible ways without warnings. Use it at your own risk.
[![GoDoc](https://godoc.org/github.com/prometheus/procfs?status.png)](https://godoc.org/github.com/prometheus/procfs)
[![Build Status](https://travis-ci.org/prometheus/procfs.svg?branch=master)](https://travis-ci.org/prometheus/procfs)
[![Go Report Card](https://goreportcard.com/badge/github.com/prometheus/procfs)](https://goreportcard.com/report/github.com/prometheus/procfs)
## 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, cpu statistics are gathered from
`/proc/stat` and are available via the root procfs package. First, the proc filesystem mount
point is initialized, and then the stat information is read.
```go
fs, err := procfs.NewFS("/proc")
stats, err := fs.Stat()
```
Some sub-packages such as `blockdevice`, require access to both the proc and sys filesystems.
```go
fs, err := blockdevice.NewFS("/proc", "/sys")
stats, err := fs.ProcDiskstats()
```
## 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 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`.
### Updating Test Fixtures
The procfs library includes a set of test fixtures which include many example files from
the `/proc` and `/sys` filesystems. These fixtures are included as a [ttar](https://github.com/ideaship/ttar) file
which is extracted automatically during testing. To add/update the test fixtures, first
ensure the `fixtures` directory is up to date by removing the existing directory and then
extracting the ttar file using `make fixtures/.unpacked` or just `make test`.
```bash
rm -rf fixtures
make test
```
Next, make the required changes to the extracted files in the `fixtures` directory. When
the changes are complete, run `make update_fixtures` to create a new `fixtures.ttar` file
based on the updated `fixtures` directory. And finally, verify the changes using
`git diff fixtures.ttar`.

Usage: $bname [-C <DIR>] -c -f <ARCHIVE> <FILE...> (create archive)
$bname -t -f <ARCHIVE> (list archive contents)
$bname [-C <DIR>] -x -f <ARCHIVE> (extract archive)
Options:
-C <DIR> (change directory)
-v (verbose)
--recursive-unlink (recursively delete existing directory if path
collides with file or directory to extract)
Example: Change to sysfs directory, create ttar file from fixtures directory
$bname -C sysfs -c -f sysfs/fixtures.ttar fixtures/
