# Changelog
|
||||
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).
|
||||
|
||||
## [1.7.0] - 2020-09-14
|
||||
### Added
|
||||
- Support JSON serialization and deserialization of primitive atomic types.
|
||||
- Support Text marshalling and unmarshalling for string atomics.
|
||||
|
||||
### Changed
|
||||
- Disallow incorrect comparison of atomic values in a non-atomic way.
|
||||
|
||||
### Removed
|
||||
- Remove dependency on `golang.org/x/{lint, tools}`.
|
||||
|
||||
## [1.6.0] - 2020-02-24
|
||||
### Changed
|
||||
- Drop library dependency on `golang.org/x/{lint, tools}`.
|
||||
|
||||
## [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.
|
||||
|
||||
## [1.5.0] - 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`.
|
||||
|
||||
## [1.4.0] - 2019-05-01
|
||||
### Added
|
||||
- Add `atomic.Error` type for atomic operations on `error` values.
|
||||
|
||||
## [1.3.2] - 2018-05-02
|
||||
### Added
|
||||
- Add `atomic.Duration` type for atomic operations on `time.Duration` values.
|
||||
|
||||
## [1.3.1] - 2017-11-14
|
||||
### Fixed
|
||||
- Revert optimization for `atomic.String.Store("")` which caused data races.
|
||||
|
||||
## [1.3.0] - 2017-11-13
|
||||
### Added
|
||||
- Add `atomic.Bool.CAS` for compare-and-swap semantics on bools.
|
||||
|
||||
### Changed
|
||||
- Optimize `atomic.String.Store("")` by avoiding an allocation.
|
||||
|
||||
## [1.2.0] - 2017-04-12
|
||||
### Added
|
||||
- Shadow `atomic.Value` from `sync/atomic`.
|
||||
|
||||
## [1.1.0] - 2017-03-10
|
||||
### Added
|
||||
- Add atomic `Float64` type.
|
||||
|
||||
### Changed
|
||||
- Support new `go.uber.org/atomic` import path.
|
||||
|
||||
## [1.0.0] - 2016-07-18

# atomic [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov] [![Go Report Card][reportcard-img]][reportcard]
|
||||
|
||||
Simple wrappers for primitive types to enforce atomic access.
|
||||
|
||||
## Installation
|
||||
|
||||
```shell
|
||||
$ go get -u go.uber.org/atomic@v1
|
||||
```
|
||||
|
||||
### Legacy Import Path
|
||||
|
||||
As of v1.5.0, the import path `go.uber.org/atomic` is the only supported way
|
||||
of using this package. If you are using Go modules, this package will fail to
|
||||
compile with the legacy import path path `github.com/uber-go/atomic`.
|
||||
|
||||
We recommend migrating your code to the new import path but if you're unable
|
||||
to do so, or if your dependencies are still using the old import path, you
|
||||
will have to add a `replace` directive to your `go.mod` file downgrading the
|
||||
legacy import path to an older version.
|
||||
|
||||
```
|
||||
replace github.com/uber-go/atomic => github.com/uber-go/atomic v1.4.0
|
||||
```
|
||||
|
||||
You can do so automatically by running the following command.
|
||||
|
||||
```shell
|
||||
$ go mod edit -replace github.com/uber-go/atomic=github.com/uber-go/atomic@v1.4.0
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
The standard library's `sync/atomic` is powerful, but it's easy to forget which
|
||||
variables must be accessed atomically. `go.uber.org/atomic` preserves all the
|
||||
functionality of the standard library, but wraps the primitive types to
|
||||
provide a safer, more convenient API.
|
||||
|
||||
```go
|
||||
var atom atomic.Uint32
|
||||
atom.Store(42)
|
||||
atom.Sub(2)
|
||||
atom.CAS(40, 11)
|
||||
```
|
||||
|
||||
See the [documentation][doc] for a complete API specification.
|
||||
|
||||
## Development Status
|
||||
|
||||
Stable.
