@ -4,37 +4,6 @@ All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [1.10.0] - 2022-08-11
### Added
- Add `atomic.Float32` type for atomic operations on `float32`.
- Add `CompareAndSwap` and `Swap` methods to `atomic.String`, `atomic.Error`,
and `atomic.Value`.
- Add generic `atomic.Pointer[T]` type for atomic operations on pointers of any
type. This is present only for Go 1.18 or higher, and is a drop-in for
replacement for the standard library's `sync/atomic.Pointer` type.
### Changed
- Deprecate `CAS` methods on all types in favor of corresponding
`CompareAndSwap` methods.
Thanks to @eNV25 and @icpd for their contributions to this release.
[1.10.0]: https://github.com/uber-go/atomic/compare/v1.9.0...v1.10.0
## [1.9.0] - 2021-07-15
### Added
- Add `Float64.Swap` to match int atomic operations.
- Add `atomic.Time` type for atomic operations on `time.Time` values.
[1.9.0]: https://github.com/uber-go/atomic/compare/v1.8.0...v1.9.0
## [1.8.0] - 2021-06-09
### Added
- Add `atomic.Uintptr` type for atomic operations on `uintptr` values.
- Add `atomic.UnsafePointer` type for atomic operations on `unsafe.Pointer` values.
[1.8.0]: https://github.com/uber-go/atomic/compare/v1.7.0...v1.8.0
## [1.7.0] - 2020-09-14

## [1.5.1] - 2019-11-19
- Fix bug where `Bool.CAS` and `Bool.Toggle` do work correctly together
causing `CAS` to fail even though the old value matches.
[1.5.1]: https://github.com/uber-go/atomic/compare/v1.5.0...v1.5.1
## [1.5.0] - 2019-10-29
### Changed
- With Go modules, only the `go.uber.org/atomic` import path is supported now.
If you need to use the old import path, please add a `replace` directive to
your `go.mod`.

guaranteeing constant throttling at saturation, instead assume that the
fractional CPU was added as a hedge for factors outside of Go's scheduler.
## v1.1.0 (2017-11-10)
- Log the new value of `GOMAXPROCS` rather than the current value.
- Make logs more explicit about whether `GOMAXPROCS` was modified or not.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age,
body size, disability, ethnicity, gender identity and expression, level of
experience, nationality, personal appearance, race, religion, or sexual
identity and orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an
appointed representative at an online or offline event. Representation of a
project may be further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at oss-conduct@uber.com. The project
team will review and investigate all complaints, and will respond in a way
that it deems appropriate to the circumstances. The project team is obligated
to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.

# Contributing
We'd love your help improving this package!
If you'd like to add new exported APIs, please [open an issue][open-issue]
describing your proposal &mdash; discussing API changes ahead of time makes
pull request review much smoother. In your issue, pull request, and any other
communications, please remember to treat your fellow contributors with
respect! We take our [code of conduct](CODE_OF_CONDUCT.md) seriously.
Note that you'll need to sign [Uber's Contributor License Agreement][cla]
before we can accept any of your contributions. If necessary, a bot will remind
you to accept the CLA when you open your pull request.
## Setup
[Fork][fork], then clone the repository:
```
mkdir -p $GOPATH/src/go.uber.org
cd $GOPATH/src/go.uber.org
git clone git@github.com:your_github_username/automaxprocs.git
cd automaxprocs
git remote add upstream https://github.com/uber-go/automaxprocs.git
git fetch upstream
```
Install the test dependencies:
```
make dependencies
```
Make sure that the tests and the linters pass:
```
make test
make lint
```
If you're not using the minor version of Go specified in the Makefile's
`LINTABLE_MINOR_VERSIONS` variable, `make lint` doesn't do anything. This is
fine, but it means that you'll only discover lint failures after you open your
pull request.
## Making Changes
Start by creating a new branch for your changes:
```
cd $GOPATH/src/go.uber.org/automaxprocs
git checkout master
git fetch upstream
git rebase upstream/master
git checkout -b cool_new_feature
```
Make your changes, then ensure that `make lint` and `make test` still pass. If
you're satisfied with your changes, push them to your fork.
```
git push origin cool_new_feature
```
Then use the GitHub UI to open a pull request.
At this point, you're waiting on us to review your changes. We *try* to respond
to issues and pull requests within a few business days, and we may suggest some
improvements or alternatives. Once your changes are approved, one of the
project maintainers will merge them.
We're much more likely to approve your changes if you:
* Add tests for new functionality.
* Write a [good commit message][commit-message].
* Maintain backward compatibility.

# automaxprocs [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
Automatically set `GOMAXPROCS` to match Linux container CPU quota.
## Installation
`go get -u go.uber.org/automaxprocs`
## Quick Start
```go
import _ "go.uber.org/automaxprocs"
func main() {
// Your application logic here.
}
```
# Performance
Data measured from Uber's internal load balancer. We ran the load balancer with 200% CPU quota (i.e., 2 cores):
| GOMAXPROCS | RPS | P50 (ms) | P99.9 (ms) |
| ------------------ | --------- | -------- | ---------- |
| 1 | 28,893.18 | 1.46 | 19.70 |
| 2 (equal to quota) | 44,715.07 | 0.84 | 26.38 |
| 3 | 44,212.93 | 0.66 | 30.07 |
| 4 | 41,071.15 | 0.57 | 42.94 |
| 8 | 33,111.69 | 0.43 | 64.32 |
| Default (24) | 22,191.40 | 0.45 | 76.19 |
When `GOMAXPROCS` is increased above the CPU quota, we see P50 decrease slightly, but see significant increases to P99. We also see that the total RPS handled also decreases.
When `GOMAXPROCS` is higher than the CPU quota allocated, we also saw significant throttling:
```
$ cat /sys/fs/cgroup/cpu,cpuacct/system.slice/[...]/cpu.stat
nr_periods 42227334
nr_throttled 131923
throttled_time 88613212216618
```
Once `GOMAXPROCS` was reduced to match the CPU quota, we saw no CPU throttling.
## Development Status: Stable
All APIs are finalized, and no breaking changes will be made in the 1.x series
of releases. Users of semver-aware dependency management systems should pin
automaxprocs to `^1`.
## Contributing
We encourage and support an active, healthy community of contributors &mdash;
including you! Details are in the [contribution guide](CONTRIBUTING.md) and
the [code of conduct](CODE_OF_CONDUCT.md). The automaxprocs maintainers keep
an eye on issues and pull requests, but you can also report any negative
conduct to oss-conduct@uber.com. That email list is a private, safe space;
even the automaxprocs maintainers don't have access, so don't hesitate to hold
us to a high standard.
