responses. #476 #414
## 0.8.0 / 2016-08-17
* [CHANGE] Registry is doing more consistency checks. This might break
existing setups that used to export inconsistent metrics.
* [CHANGE] Pushing to Pushgateway moved to package `push` and changed to allow
arbitrary grouping.
* [CHANGE] Removed `SelfCollector`.

`extraction`.
* [CHANGE] Deprecated a number of functions.
* [FEATURE] Allow custom registries. Added `Registerer` and `Gatherer`
interfaces.
* [FEATURE] Separated HTTP exposition, allowing custom HTTP handlers (package
`promhttp`) and enabling the creation of other exposition mechanisms.
* [FEATURE] `MustRegister` is variadic now, allowing registration of many
collectors in one call.
* [FEATURE] Added HTTP API v1 package.
* [ENHANCEMENT] Numerous documentation improvements.
* [ENHANCEMENT] Improved metric sorting.
* [ENHANCEMENT] Inlined fnv64a hashing for improved performance.
* [ENHANCEMENT] Several test improvements.
* [BUGFIX] Handle collisions in MetricVec.
## 0.7.0 / 2015-07-27
* [CHANGE] Rename ExporterLabelPrefix to ExportedLabelPrefix.
* [BUGFIX] Closed gaps in metric consistency check.
* [BUGFIX] Validate LabelName/LabelSet on JSON unmarshaling.
* [ENHANCEMENT] Document the possibility to create "empty" metrics in
a metric vector.
* [ENHANCEMENT] Fix and clarify various doc comments and the README.md.
* [ENHANCEMENT] (Kind of) solve "The Proxy Problem" of http.InstrumentHandler.
* [ENHANCEMENT] Change responseWriterDelegator.written to int64.
## 0.6.0 / 2015-06-01
* [CHANGE] Rename process_goroutines to go_goroutines.
* [ENHANCEMENT] Validate label names during YAML decoding.
* [ENHANCEMENT] Add LabelName regular expression.
* [BUGFIX] Ensure alignment of struct members for 32-bit systems.
## 0.5.0 / 2015-05-06
* [BUGFIX] Removed a weakness in the fingerprinting aka signature code.
This makes fingerprinting slower and more allocation-heavy, but the
weakness was too severe to be tolerated.
* [CHANGE] As a result of the above, Metric.Fingerprint is now returning
a different fingerprint. To keep the same fingerprint, the new method
Metric.FastFingerprint was introduced, which will be used by the
Prometheus server for storage purposes (implying that a collision
detection has to be added, too).
* [ENHANCEMENT] The Metric.Equal and Metric.Before do not depend on
fingerprinting anymore, removing the possibility of an undetected
fingerprint collision.
* [FEATURE] The Go collector in the exposition library includes garbage
collection stats.
* [FEATURE] The exposition library allows to create constant "throw-away"
summaries and histograms.
* [CHANGE] A number of new reserved labels and prefixes.
## 0.4.0 / 2015-04-08
* [CHANGE] Return NaN when Summaries have no observations yet.
* [BUGFIX] Properly handle Summary decay upon Write().
* [BUGFIX] Fix the documentation link to the consumption library.
* [FEATURE] Allow the metric family injection hook to merge with existing
metric families.
* [ENHANCEMENT] Removed cgo dependency and conditional compilation of procfs.
* [MAINTENANCE] Adjusted to changes in matttproud/golang_protobuf_extensions.
## 0.3.2 / 2015-03-11
* [BUGFIX] Fixed the receiver type of COWMetric.Set(). This method is
only used by the Prometheus server internally.
* [CLEANUP] Added licenses of vendored code left out by godep.
## 0.3.1 / 2015-03-04
* [ENHANCEMENT] Switched fingerprinting functions from own free list to
sync.Pool.
* [CHANGE] Makefile uses Go 1.4.2 now (only relevant for examples and tests).
## 0.3.0 / 2015-03-03
* [CHANGE] Changed the fingerprinting for metrics. THIS WILL INVALIDATE ALL
PERSISTED FINGERPRINTS. IF YOU COMPILE THE PROMETHEUS SERVER WITH THIS
VERSION, YOU HAVE TO WIPE THE PREVIOUSLY CREATED STORAGE.
* [CHANGE] LabelValuesToSignature removed. (Nobody had used it, and it was
arguably broken.)
* [CHANGE] Vendored dependencies. Those are only used by the Makefile. If
client_golang is used as a library, the vendoring will stay out of your way.
* [BUGFIX] Remove a weakness in the fingerprinting for metrics. (This made
the fingerprinting change above necessary.)
* [FEATURE] Added new fingerprinting functions SignatureForLabels and
SignatureWithoutLabels to be used by the Prometheus server. These functions
require fewer allocations than the ones currently used by the server.
## 0.2.0 / 2015-02-23
* [FEATURE] Introduce new Histagram metric type.
* [CHANGE] Ignore process collector errors for now (better error handling
pending).
* [CHANGE] Use clear error interface for process pidFn.
* [BUGFIX] Fix Go download links for several archs and OSes.
* [ENHANCEMENT] Massively improve Gauge and Counter performance.
* [ENHANCEMENT] Catch illegal label names for summaries in histograms.
* [ENHANCEMENT] Reduce allocations during fingerprinting.
* [ENHANCEMENT] Remove cgo dependency. procfs package will only be included if
both cgo is available and the build is for an OS with procfs.
* [CLEANUP] Clean up code style issues.
* [CLEANUP] Mark slow test as such and exclude them from travis.
* [CLEANUP] Update protobuf library package name.
* [CLEANUP] Updated vendoring of beorn7/perks.
## 0.1.0 / 2015-02-02
* [CLEANUP] Introduced semantic versioning and changelog. From now on,
changes will be reported in this file.

# Prometheus Go client library
[![Build Status](https://travis-ci.org/prometheus/client_golang.svg?branch=master)](https://travis-ci.org/prometheus/client_golang)
[![Go Report Card](https://goreportcard.com/badge/github.com/prometheus/client_golang)](https://goreportcard.com/report/github.com/prometheus/client_golang)
[![go-doc](https://godoc.org/github.com/prometheus/client_golang?status.svg)](https://godoc.org/github.com/prometheus/client_golang)
This is the [Go](http://golang.org) client library for
[Prometheus](http://prometheus.io). It has two separate parts, one for
instrumenting application code, and one for creating clients that talk to the
Prometheus HTTP API.
__This library requires Go1.7 or later.__
## Important note about releases, versioning, tagging, and stability
While our goal is to follow [Semantic Versioning](https://semver.org/), this
repository is still pre-1.0.0. To quote the
[Semantic Versioning spec](https://semver.org/#spec-item-4): “Anything may
change at any time. The public API should not be considered stable.” We know
that this is at odds with the widespread use of this library. However, just
declaring something 1.0.0 doesn't make it 1.0.0. Instead, we are working
towards a 1.0.0 release that actually deserves its major version number.
Having said that, we aim for always keeping the tip of master in a workable
state. We occasionally tag versions and track their changes in CHANGELOG.md,
but this happens mostly to keep dependency management tools happy and to give
people a handle they can talk about easily. In particular, all commits in the
master branch have passed the same testing and reviewing. There is no QA
process in place that would render tagged commits more stable or better tested
than others.
There is a plan behind the current (pre-1.0.0) versioning, though:
- v0.9 is the “production release”, currently tracked in the master
branch. “Patch” releases will usually be just bug fixes, indeed, but
important new features that do not require invasive code changes might also
be included in those. We do not plan any breaking changes from one v0.9.x
release to any later v0.9.y release, but nothing is guaranteed. Since the
master branch will eventually be switched over to track the upcoming v0.10
(see below), we recommend to tell your dependency management tool of choice
to use the latest v0.9.x release, at least for your production software. In
that way, you should get bug fixes and non-invasive, low-risk new features
without the need to change anything on your part.
- v0.10 is a planned release that will have a _lot_ of breaking changes
(despite being only a “minor” release in the Semantic Versioning terminology,
but as said, pre-1.0.0 means nothing is guaranteed). Essentially, we have
been piling up feature requests that require breaking changes for a while,
and they are all collected in the
[v0.10 milestone](https://github.com/prometheus/client_golang/milestone/2).
Since there will be so many breaking changes, the development for v0.10 is
currently not happening in the master branch, but in the
[dev-0.10 branch](https://github.com/prometheus/client_golang/tree/dev-0.10).
It will violently change for a while, and it will definitely be in a
non-working state now and then. It should only be used for sneak-peaks and
discussions of the new features and designs.
- Once v0.10 is ready for real-life use, it will be merged into the master
branch (which is the reason why you should lock your dependency management
tool to v0.9.x and only migrate to v0.10 when both you and v0.10 are ready
for it). In the ideal case, v0.10 will be the basis for the future v1.0
release, but we cannot provide an ETA at this time.
## Instrumenting applications
[![code-coverage](http://gocover.io/_badge/github.com/prometheus/client_golang/prometheus)](http://gocover.io/github.com/prometheus/client_golang/prometheus) [![go-doc](https://godoc.org/github.com/prometheus/client_golang/prometheus?status.svg)](https://godoc.org/github.com/prometheus/client_golang/prometheus)
The
[`prometheus` directory](https://github.com/prometheus/client_golang/tree/master/prometheus)
contains the instrumentation library. See the
[guide](https://prometheus.io/docs/guides/go-application/) on the Prometheus
website to learn more about instrumenting applications.
The
[`examples` directory](https://github.com/prometheus/client_golang/tree/master/examples)
contains simple examples of instrumented code.
## Client for the Prometheus HTTP API
[![code-coverage](http://gocover.io/_badge/github.com/prometheus/client_golang/api/prometheus/v1)](http://gocover.io/github.com/prometheus/client_golang/api/prometheus/v1) [![go-doc](https://godoc.org/github.com/prometheus/client_golang/api/prometheus?status.svg)](https://godoc.org/github.com/prometheus/client_golang/api)
The
[`api/prometheus` directory](https://github.com/prometheus/client_golang/tree/master/api/prometheus)
contains the client for the
[Prometheus HTTP API](http://prometheus.io/docs/querying/api/). It allows you
to write Go applications that query time series data from a Prometheus
server. It is still in alpha stage.
## Where is `model`, `extraction`, and `text`?
The `model` packages has been moved to
[`prometheus/common/model`](https://github.com/prometheus/common/tree/master/model).
The `extraction` and `text` packages are now contained in
[`prometheus/common/expfmt`](https://github.com/prometheus/common/tree/master/expfmt).

# Contributing
Prometheus uses GitHub to manage reviews of pull requests.
* If you have a trivial fix or improvement, go ahead and create a pull request,
addressing (with `@...`) the 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.
* 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](http://peter.bourgon.org/go-in-production/#formatting-and-style).
