# Changelog
|
||||
|
||||
## v7.2
|
||||
|
||||
- Existing `HMSet` is renamed to `HSet` and old deprecated `HMSet` is restored for Redis 3 users.
|
||||
|
||||
## v7.1
|
||||
|
||||
- Existing `Cmd.String` is renamed to `Cmd.Text`. New `Cmd.String` implements `fmt.Stringer` interface.
|
||||
|
||||
## v7
|
||||
|
||||
- *Important*. Tx.Pipeline now returns a non-transactional pipeline. Use Tx.TxPipeline for a transactional pipeline.
|
||||
- WrapProcess is replaced with more convenient AddHook that has access to context.Context.
|
||||
- WithContext now can not be used to create a shallow copy of the client.
|
||||
- New methods ProcessContext, DoContext, and ExecContext.
|
||||
- Client respects Context.Deadline when setting net.Conn deadline.
|
||||
- Client listens on Context.Done while waiting for a connection from the pool and returns an error when context context is cancelled.
|
||||
- Add PubSub.ChannelWithSubscriptions that sends `*Subscription` in addition to `*Message` to allow detecting reconnections.
|
||||
- `time.Time` is now marshalled in RFC3339 format. `rdb.Get("foo").Time()` helper is added to parse the time.
|
||||
- `SetLimiter` is removed and added `Options.Limiter` instead.
|
||||
- `HMSet` is deprecated as of Redis v4.
|
||||
|
||||
## v6.15
|
||||
|
||||
- Cluster and Ring pipelines process commands for each node in its own goroutine.
|
||||
|
||||
## 6.14
|
||||
|
||||
- Added Options.MinIdleConns.
|
||||
- Added Options.MaxConnAge.
|
||||
- PoolStats.FreeConns is renamed to PoolStats.IdleConns.
|
||||
- Add Client.Do to simplify creating custom commands.
|
||||
- Add Cmd.String, Cmd.Int, Cmd.Int64, Cmd.Uint64, Cmd.Float64, and Cmd.Bool helpers.
|
||||
- Lower memory usage.
|
||||
|
||||
## v6.13
|
||||
|
||||
- Ring got new options called `HashReplicas` and `Hash`. It is recommended to set `HashReplicas = 1000` for better keys distribution between shards.
|
||||
- Cluster client was optimized to use much less memory when reloading cluster state.
|
||||
- PubSub.ReceiveMessage is re-worked to not use ReceiveTimeout so it does not lose data when timeout occurres. In most cases it is recommended to use PubSub.Channel instead.
|
||||
- Dialer.KeepAlive is set to 5 minutes by default.
|
||||
|
||||
## v6.12
|
||||
|
||||
- ClusterClient got new option called `ClusterSlots` which allows to build cluster of normal Redis Servers that don't have cluster mode enabled. See https://godoc.org/github.com/go-redis/redis#example-NewClusterClient--ManualSetup

|
||||
|
||||
## Installation
|
||||
|
||||
go-redis requires a Go version with [Modules](https://github.com/golang/go/wiki/Modules) support and uses import versioning. So please make sure to initialize a Go module before installing go-redis:
|
||||
|
||||
``` shell
|
||||
go mod init github.com/my/repo
|
||||
go get github.com/go-redis/redis/v7
|
||||
```
|
||||
|
||||
Import:
|
||||
|
||||
``` go
|
||||
import "github.com/go-redis/redis/v7"
|
||||
```
|
||||
|
||||
## Quickstart
|
||||
|
||||
``` go
|
||||
func ExampleNewClient() {
|
||||
client := redis.NewClient(&redis.Options{
|
||||
Addr: "localhost:6379",
|
||||
Password: "", // no password set
|
||||
DB: 0, // use default DB
|
||||
})
|
||||
|
||||
pong, err := client.Ping().Result()
|
||||
fmt.Println(pong, err)
|
||||
// Output: PONG <nil>
|
||||
}
|
||||
|
||||
func ExampleClient() {
|
||||
client := redis.NewClient(&redis.Options{
|
||||
Addr: "localhost:6379",
|
||||
Password: "", // no password set
|
||||
DB: 0, // use default DB
|
||||
})
|
||||
err := client.Set("key", "value", 0).Err()
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
||||
val, err := client.Get("key").Result()
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
fmt.Println("key", val)
|
||||
|
||||
val2, err := client.Get("key2").Result()
|
||||
if err == redis.Nil {
|
||||
fmt.Println("key2 does not exist")
|
||||
} else if err != nil {
|
||||
panic(err)
|
||||
} else {
|
||||
fmt.Println("key2", val2)
|
||||
}
|
||||
// Output: key value
|
||||
// key2 does not exist
|
||||
}
|
||||
```
|
||||
|
||||
## Howto
|
||||
|
||||
Please go through [examples](https://godoc.org/github.com/go-redis/redis#pkg-examples) to get an idea how to use this package.
|
||||
|
||||
## Look and feel
|
||||
|
||||
Some corner cases:
|
||||
|
||||
``` go
|
||||
// SET key value EX 10 NX
|
||||
set, err := client.SetNX("key", "value", 10*time.Second).Result()
|
||||
|
||||
// SORT list LIMIT 0 2 ASC
|
||||
vals, err := client.Sort("list", &redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
|
||||
|
||||
// ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
|
||||
vals, err := client.ZRangeByScoreWithScores("zset", &redis.ZRangeBy{
|
||||
Min: "-inf",
|
||||
Max: "+inf",
|
||||
Offset: 0,
|
||||
Count: 2,
|
||||
}).Result()
|
||||
|
||||
// ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
|
||||
vals, err := client.ZInterStore("out", &redis.ZStore{
|
||||
Keys: []string{"zset1", "zset2"},
|
||||
Weights: []int64{2, 3}
|
||||
}).Result()
|
||||
|
||||
// EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
|
||||
vals, err := client.Eval("return {KEYS[1],ARGV[1]}", []string{"key"}, "hello").Result()
|
||||
|
||||
// custom command
|
||||
res, err := client.Do("set", "key", "value").Result()
|
||||
```

|
||||
- [Instrumentation](https://pkg.go.dev/github.com/go-redis/redis/v8?tab=doc#ex-package--Instrumentation).
|
||||
|
||||
## Installation
|
||||
|
||||
go-redis supports 2 last Go versions and requires a Go version with
|
||||
[modules](https://github.com/golang/go/wiki/Modules) support. So make sure to initialize a Go
|
||||
module:
|
||||
|
||||
```shell
|
||||
go mod init github.com/my/repo
|
||||
```
|
||||
|
||||
And then install go-redis/v8 (note _v8_ in the import; omitting it is a popular mistake):
|
||||
|
||||
```shell
|
||||
go get github.com/go-redis/redis/v8
|
||||
```
|
||||
|
||||
## Quickstart
|
||||
|
||||
```go
|
||||
import (
|
||||
"context"
|
||||
"github.com/go-redis/redis/v8"
|
||||
)
|
||||
|
||||
var ctx = context.Background()
|
||||
|
||||
func ExampleClient() {
|
||||
rdb := redis.NewClient(&redis.Options{
|
||||
Addr: "localhost:6379",
|
||||
Password: "", // no password set
|
||||
DB: 0, // use default DB
|
||||
})
|
||||
|
||||
err := rdb.Set(ctx, "key", "value", 0).Err()
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
||||
val, err := rdb.Get(ctx, "key").Result()
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
fmt.Println("key", val)
|
||||
|
||||
val2, err := rdb.Get(ctx, "key2").Result()
|
||||
if err == redis.Nil {
|
||||
fmt.Println("key2 does not exist")
|
||||
} else if err != nil {
|
||||
panic(err)
|
||||
} else {
|
||||
fmt.Println("key2", val2)
|
||||
}
|
||||
// Output: key value
|
||||
// key2 does not exist
|
||||
}
|
||||
```
|
||||
|
||||
## Look and feel
|
||||
|
||||
Some corner cases:
|
||||
|
||||
```go
|
||||
// SET key value EX 10 NX
|
||||
set, err := rdb.SetNX(ctx, "key", "value", 10*time.Second).Result()
|
||||
|
||||
// SET key value keepttl NX
|
||||
set, err := rdb.SetNX(ctx, "key", "value", redis.KeepTTL).Result()
|
||||
|
||||
// SORT list LIMIT 0 2 ASC
|
||||
vals, err := rdb.Sort(ctx, "list", &redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
|
||||
|
||||
// ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
|
||||
vals, err := rdb.ZRangeByScoreWithScores(ctx, "zset", &redis.ZRangeBy{
|
||||
Min: "-inf",
|
||||
Max: "+inf",
|
||||
Offset: 0,
|
||||
Count: 2,
|
||||
}).Result()
|
||||
|
||||
// ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
|
||||
vals, err := rdb.ZInterStore(ctx, "out", &redis.ZStore{
|
||||
Keys: []string{"zset1", "zset2"},
|
||||
Weights: []int64{2, 3}
|
||||
}).Result()
|
||||
|
||||
// EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
|
||||
vals, err := rdb.Eval(ctx, "return {KEYS[1],ARGV[1]}", []string{"key"}, "hello").Result()
|
||||
|
||||
// custom command
|
||||
res, err := rdb.Do(ctx, "set", "key", "value").Result()
|
||||
```
|
||||
## Run the test
|
||||
go-redis will start a redis-server and run the test cases.
|
||||
|
||||
The paths of redis-server bin file and redis config file are definded in `main_test.go`:
|
||||
```
|
||||
var (
|
||||
redisServerBin, _ = filepath.Abs(filepath.Join("testdata", "redis", "src", "redis-server"))
|
||||
redisServerConf, _ = filepath.Abs(filepath.Join("testdata", "redis", "redis.conf"))
|
||||
)
|
||||
```
|
||||
|
||||
For local testing, you can change the variables to refer to your local files, or create a soft link to the corresponding folder for redis-server and copy the config file to `testdata/redis/`:
|
||||
```
|
||||
ln -s /usr/bin/redis-server ./go-redis/testdata/redis/src
|
||||
cp ./go-redis/testdata/redis.conf ./go-redis/testdata/redis/
|
||||
```
|
||||
|
||||
Lastly, run:
|
||||
```
|
||||
go test
|
||||
```
|
||||

||||

# Contributing to opentelemetry-go
|
||||
|
||||
The Go special interest group (SIG) meets regularly. See the
|
||||
OpenTelemetry
|
||||
[community](https://github.com/open-telemetry/community#golang-sdk)
|
||||
repo for information on this and other language SIGs.
|
||||
|
||||
See the [public meeting
|
||||
notes](https://docs.google.com/document/d/1A63zSWX0x2CyCK_LoNhmQC4rqhLpYXJzXbEPDUQ2n6w/edit#heading=h.9tngw7jdwd6b)
|
||||
for a summary description of past meetings. To request edit access,
|
||||
join the meeting or get in touch on
|
||||
[Gitter](https://gitter.im/open-telemetry/opentelemetry-go).
|
||||
|
||||
## Development
|
||||
|
||||
You can view and edit the source code by cloning this repository:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/open-telemetry/opentelemetry-go.git
|
||||
```
|
||||
|
||||
Run `make test` to run the tests instead of `go test`.
|
||||
|
||||
There are some generated files checked into the repo. To make sure
|
||||
that the generated files are up-to-date, run `make` (or `make
|
||||
precommit` - the `precommit` target is the default).
|
||||
|
||||
The `precommit` target also fixes the formatting of the code and
|
||||
checks the status of the go module files.
|
||||
|
||||
If after running `make precommit` the output of `git status` contains
|
||||
`nothing to commit, working tree clean` then it means that everything
|
||||
is up-to-date and properly formatted.
|
||||
|
||||
## Pull Requests
|
||||
|
||||
### How to Send Pull Requests
|
||||
|
||||
Everyone is welcome to contribute code to `opentelemetry-go` via
|
||||
GitHub pull requests (PRs).
|
||||
|
||||
To create a new PR, fork the project in GitHub and clone the upstream
|
||||
repo:
|
||||
|
||||
```sh
|
||||
$ go get -d go.opentelemetry.io/otel
|
||||
```
|
||||
|
||||
(This may print some warning about "build constraints exclude all Go
|
||||
files", just ignore it.)
|
||||
|
||||
This will put the project in `${GOPATH}/src/go.opentelemetry.io/otel`. You
|
||||
can alternatively use `git` directly with:
|
||||
|
||||
```sh
|
||||
$ git clone https://github.com/open-telemetry/opentelemetry-go
|
||||
```
|
||||
|
||||
(Note that `git clone` is *not* using the `go.opentelemetry.io/otel` name -
|
||||
that name is a kind of a redirector to GitHub that `go get` can
|
||||
understand, but `git` does not.)
|
||||
|
||||
This would put the project in the `opentelemetry-go` directory in
|
||||
current working directory.
|
||||
|
||||
Enter the newly created directory and add your fork as a new remote:
|
||||
|
||||
```sh
|
||||
$ git remote add <YOUR_FORK> git@github.com:<YOUR_GITHUB_USERNAME>/opentelemetry-go
|
||||
```
|
||||
|
||||
Check out a new branch, make modifications, run linters and tests, update
|
||||
`CHANGELOG.md`, and push the branch to your fork:
|
||||
|
||||
```sh
|
||||
$ git checkout -b <YOUR_BRANCH_NAME>
|
||||
# edit files
|
||||
# update changelog
|
||||
$ make precommit
|
||||
$ git add -p
|
||||
$ git commit
|
||||
$ git push <YOUR_FORK> <YOUR_BRANCH_NAME>
|
||||
```
|
||||
|
||||
Open a pull request against the main `opentelemetry-go` repo. Be sure to add the pull
|
||||
request ID to the entry you added to `CHANGELOG.md`.
|
||||
|
||||
### How to Receive Comments
|
||||
|
||||
* If the PR is not ready for review, please put `[WIP]` in the title,
|
||||
tag it as `work-in-progress`, or mark it as
|
||||
[`draft`](https://github.blog/2019-02-14-introducing-draft-pull-requests/).
|
||||
* Make sure CLA is signed and CI is clear.
|
||||
|
||||
### How to Get PRs Merged
|
||||
|
||||
A PR is considered to be **ready to merge** when:
|
||||
|
||||
* It has received two approvals from Collaborators/Maintainers (at
|
||||
different companies). This is not enforced through technical means
|
||||
and a PR may be **ready to merge** with a single approval if the change
|
||||
and its approach have been discussed and consensus reached.
|
||||
* Major feedbacks are resolved.
|
||||
* It has been open for review for at least one working day. This gives
|
||||
people reasonable time to review.
|
||||
* Trivial changes (typo, cosmetic, doc, etc.) do not have to wait for
|
||||
one day and may be merged with a single Maintainer's approval.
|
||||
* `CHANGELOG.md` has been updated to reflect what has been
|
||||
added, changed, removed, or fixed.
|
||||
* Urgent fix can take exception as long as it has been actively
|
||||
communicated.
|
||||
|
||||
Any Maintainer can merge the PR once it is **ready to merge**.
|
||||
|
||||
## Design Choices
|
||||
|
||||
As with other OpenTelemetry clients, opentelemetry-go follows the
|
||||
[opentelemetry-specification](https://github.com/open-telemetry/opentelemetry-specification).
|
||||
|
||||
It's especially valuable to read through the [library
|
||||
guidelines](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/library-guidelines.md).
|
||||
|
||||
### Focus on Capabilities, Not Structure Compliance
|
||||
|
||||
OpenTelemetry is an evolving specification, one where the desires and
|
||||
use cases are clear, but the method to satisfy those uses cases are
|
||||
not.
|
||||
|
||||
As such, Contributions should provide functionality and behavior that
|
||||
conforms to the specification, but the interface and structure is
|
||||
flexible.
|
||||
|
||||
It is preferable to have contributions follow the idioms of the
|
||||
language rather than conform to specific API names or argument
|
||||
patterns in the spec.
|
||||
|
||||
For a deeper discussion, see:
|
||||
https://github.com/open-telemetry/opentelemetry-specification/issues/165
|
||||
|
||||
## Style Guide
|
||||
|
||||
One of the primary goals of this project is that it is actually used by
|
||||
developers. With this goal in mind the project strives to build
|
||||
user-friendly and idiomatic Go code adhering to the Go community's best
|
||||
practices.
|
||||
|
||||
For a non-comprehensive but foundational overview of these best practices
|
||||
the [Effective Go](https://golang.org/doc/effective_go.html) documentation
|
||||
is an excellent starting place.
|
||||
|
||||
As a convenience for developers building this project the `make precommit`
|
||||
will format, lint, validate, and in some cases fix the changes you plan to
|
||||
submit. This check will need to pass for your changes to be able to be
|
||||
merged.
|
||||
|
||||
In addition to idiomatic Go, the project has adopted certain standards for
|
||||
implementations of common patterns. These standards should be followed as a
|
||||
default, and if they are not followed documentation needs to be included as
|
||||
to the reasons why.
|
||||
|
||||
### Configuration
|
||||
|
||||
When creating an instantiation function for a complex `struct` it is useful
|
||||
to allow variable number of options to be applied. However, the strong type
|
||||
system of Go restricts the function design options. There are a few ways to
|
||||
solve this problem, but we have landed on the following design.
|
||||
|
||||
#### `config`
|
||||
|
||||
Configuration should be held in a `struct` named `config`, or prefixed with
|
||||
specific type name this Configuration applies to if there are multiple
|
||||
`config` in the package. This `struct` must contain configuration options.
|
||||
|
||||
```go
|
||||
// config contains configuration options for a thing.
|
||||
type config struct {
|
||||
// options ...
|
||||
}
|
||||
```
|
||||
|
||||
In general the `config` `struct` will not need to be used externally to the
|
||||
package and should be unexported. If, however, it is expected that the user
|
||||
will likely want to build custom options for the configuration, the `config`
|
||||
should be exported. Please, include in the documentation for the `config`
|
||||
how the user can extend the configuration.
|
||||
|
||||
It is important that `config` are not shared across package boundaries.
|
||||
Meaning a `config` from one package should not be directly used by another.
|
||||
|
||||
Optionally, it is common to include a `newConfig` function (with the same
|
||||
naming scheme). This function wraps any defaults setting and looping over
|
||||
all options to create a configured `config`.
|
||||
|
||||
```go
|
||||
// newConfig returns an appropriately configured config.
|
||||
func newConfig([]Option) config {
|
||||
// Set default values for config.
|
||||
config := config{/* […] */}
|
||||
for _, option := range options {
|
||||
option.Apply(&config)
|
||||
}
|
||||
// Preform any validation here.
|
||||
return config
|
||||
}
|
||||
```
|
||||
|
||||
If validation of the `config` options is also preformed this can return an
|
||||
error as well that is expected to be handled by the instantiation function
|
||||
or propagated to the user.
|
||||
|
||||
Given the design goal of not having the user need to work with the `config`,
|
||||
the `newConfig` function should also be unexported.
|
||||
|
||||
#### `Option`
|
||||
|
||||
To set the value of the options a `config` contains, a corresponding
|
||||
`Option` interface type should be used.
|
||||
|
||||
```go
|
||||
type Option interface {
|
||||
Apply(*config)
|
||||
}
|
||||
```
|
||||
|
||||
The name of the interface should be prefixed in the same way the
|
||||
corresponding `config` is (if at all).
|
||||
|
||||
#### Options
|
||||
|
||||
All user configurable options for a `config` must have a related unexported
|
||||
implementation of the `Option` interface and an exported configuration
|
||||
function that wraps this implementation.
|
||||
|
||||
The wrapping function name should be prefixed with `With*` (or in the
|
||||
special case of a boolean options `Without*`) and should have the following
|
||||
function signature.
|
||||
|
||||
```go
|
||||
func With*(…) Option { … }
|
||||
```
|
||||
|
||||
##### `bool` Options
|
||||
|
||||
```go
|
||||
type defaultFalseOption bool
|
||||
|
||||
func (o defaultFalseOption) Apply(c *config) {
|
||||
c.Bool = bool(o)
|
||||
}
|
||||
|
||||
// WithOption sets a T* to have an option included.
|
||||
func WithOption() Option {
|
||||
return defaultFalseOption(true)
|
||||
}
|
||||
```
|
||||
|
||||
```go
|
||||
type defaultTrueOption bool
|
||||
|
||||
func (o defaultTrueOption) Apply(c *config) {
|
||||
c.Bool = bool(o)
|
||||
}
|
||||
|
||||
// WithoutOption sets a T* to have Bool option excluded.
|
||||
func WithoutOption() Option {
|
||||
return defaultTrueOption(false)
|
||||
}
|
||||
````
|
||||
|
||||
##### Declared Type Options
|
||||
|
||||
```go
|
||||
type myTypeOption struct {
|
||||
MyType MyType
|
||||
}
|
||||
|
||||
func (o myTypeOption) Apply(c *config) {
|
||||
c.MyType = o.MyType
|
||||
}
|
||||
|
||||
// WithMyType sets T* to have include MyType.
|
||||
func WithMyType(t MyType) Option {
|
||||
return myTypeOption{t}
|
||||
}
|
||||
```
|
||||
|
||||
#### Instantiation
|
||||
|
||||
Using this configuration pattern to configure instantiation with a `New*`
|
||||
function.
|
||||
|
||||
```go
|
||||
func NewT*(options ...Option) T* {…}
|
||||
```
|
||||
|
||||
Any required parameters can be declared before the variadic `options`.
|
||||
|
||||
#### Dealing with Overlap
|
||||
|
||||
Sometimes there are multiple complex `struct` that share common
|
||||
configuration and also have distinct configuration. To avoid repeated
|
||||
portions of `config`s, a common `config` can be used with the union of
|
||||
options being handled with the `Option` interface.
|
||||
|
||||
For example.
|
||||
|
||||
```go
|
||||
// config holds options for all animals.
|
||||
type config struct {
|
||||
Weight float64
|
||||
Color string
|
||||
MaxAltitude float64
|
||||
}
|
||||
|
||||
// DogOption apply Dog specific options.
|
||||
type DogOption interface {
|
||||
ApplyDog(*config)
|
||||
}
|
||||
|
||||
// BirdOption apply Bird specific options.
|
||||
type BirdOption interface {
|
||||
ApplyBird(*config)
|
||||
}
|
||||
|
||||
// Option apply options for all animals.
|
||||
type Option interface {
|
||||
BirdOption
|
||||
DogOption
|
||||
}
|
||||
|
||||
type weightOption float64
|
||||
func (o weightOption) ApplyDog(c *config) { c.Weight = float64(o) }
|
||||
func (o weightOption) ApplyBird(c *config) { c.Weight = float64(o) }
|
||||
func WithWeight(w float64) Option { return weightOption(w) }
|
||||
|
||||
type furColorOption string
|
||||
func (o furColorOption) ApplyDog(c *config) { c.Color = string(o) }
|
||||
func WithFurColor(c string) DogOption { return furColorOption(c) }
|
||||
|
||||
type maxAltitudeOption float64
|
||||
func (o maxAltitudeOption) ApplyBird(c *config) { c.MaxAltitude = float64(o) }
|
||||
func WithMaxAltitude(a float64) BirdOption { return maxAltitudeOption(a) }
|
||||
|
||||
func NewDog(name string, o ...DogOption) Dog {…}
|
||||
func NewBird(name string, o ...BirdOption) Bird {…}
|
||||
```
|
||||
|
||||
### Interface Type
|
||||
|
||||
To allow other developers to better comprehend the code, it is important
|
||||
to ensure it is sufficiently documented. One simple measure that contributes
|
||||
to this aim is self-documenting by naming method parameters. Therefore,
|
||||
where appropriate, methods of every exported interface type should have
|
||||
their parameters appropriately named.

TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||
|
||||
1. Definitions.
|
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction,
|
||||
and distribution as defined by Sections 1 through 9 of this document.
|
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by
|
||||
the copyright owner that is granting the License.
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all
|
||||
other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
|
||||
To apply the Apache License to your work, attach the following
|
||||
boilerplate notice, with the fields enclosed by brackets "[]"
|
||||
replaced with your own identifying information. (Don't include
|
||||
the brackets!) The text should be enclosed in the appropriate
|
||||
comment syntax for the file format. We also recommend that a
|
||||
file or class name and description of purpose be included on the
|
||||
same "printed page" as the copyright notice for easier
|
||||
identification within third-party archives.

The Go [OpenTelemetry](https://opentelemetry.io/) implementation.
|
||||
|
||||
## Project Status
|
||||
|
||||
**Warning**: this project is currently in a pre-GA phase. Backwards
|
||||
incompatible changes may be introduced in subsequent minor version releases as
|
||||
we work to track the evolving OpenTelemetry specification and user feedback.
|
||||
|
||||
Our progress towards a GA release candidate is tracked in [this project
|
||||
board](https://github.com/orgs/open-telemetry/projects/5). This release
|
||||
candidate will follow semantic versioning and will be released with a major
|
||||
version greater than zero.
|
||||
|
||||
Progress and status specific to this repository is tracked in our local
|
||||
[project boards](https://github.com/open-telemetry/opentelemetry-go/projects)
|
||||
and
|
||||
[milestones](https://github.com/open-telemetry/opentelemetry-go/milestones).
|
||||
|
||||
Project versioning information and stability guarantees can be found in the
|
||||
[versioning documentation](./VERSIONING.md).
|
||||
|
||||
## Getting Started
|
||||
|
||||
You can find a getting started guide on [opentelemetry.io](https://opentelemetry.io/docs/go/getting-started/).
|
||||
|
||||
OpenTelemetry's goal is to provide a single set of APIs to capture distributed
|
||||
traces and metrics from your application and send them to an observability
|
||||
platform. This project allows you to do just that for applications written in
|
||||
Go. There are two steps to this process: instrument your application, and
|
||||
configure an exporter.
|
||||
|
||||
### Instrumentation
|
||||
|
||||
To start capturing distributed traces and metric events from your application
|
||||
it first needs to be instrumented. The easiest way to do this is by using an
|
||||
instrumentation library for your code. Be sure to check out [the officially
|
||||
supported instrumentation
|
||||
libraries](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/master/instrumentation).
|
||||
|
||||
If you need to extend the telemetry an instrumentation library provides or want
|
||||
to build your own instrumentation for your application directly you will need
|
||||
to use the
|
||||
[go.opentelemetry.io/otel/api](https://pkg.go.dev/go.opentelemetry.io/otel/api)
|
||||
package. The included [examples](./example/) are a good way to see some
|
||||
practical uses of this process.
|
||||
|
||||
### Export
|
||||
|
||||
Now that your application is instrumented to collect telemetry, it needs an
|
||||
export pipeline to send that telemetry to an observability platform.
|
||||
|
||||
You can find officially supported exporters [here](./exporters/) and in the
|
||||
companion [contrib
|
||||
repository](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/master/exporters/metric).
|
||||
Additionally, there are many vendor specific or 3rd party exporters for
|
||||
OpenTelemetry. These exporters are broken down by
|
||||
[trace](https://pkg.go.dev/go.opentelemetry.io/otel/sdk/export/trace?tab=importedby)
|
||||
and
|
||||
[metric](https://pkg.go.dev/go.opentelemetry.io/otel/sdk/export/metric?tab=importedby)
|
||||
support.

||||

# Release Process
|
||||
|
||||
## Pre-Release
|
||||
|
||||
Update go.mod for submodules to depend on the new release which will happen in the next step.
|
||||
|
||||
1. Run the pre-release script. It creates a branch `pre_release_<new tag>` that will contain all release changes.
|
||||
|
||||
```
|
||||
./pre_release.sh -t <new tag>
|
||||
```
|
||||
|
||||
2. Verify the changes.
|
||||
|
||||
```
|
||||
git diff master
|
||||
```
|
||||
|
||||
This should have changed the version for all modules to be `<new tag>`.
|
||||
|
||||
3. Update the [Changelog](./CHANGELOG.md).
|
||||
- Make sure all relevant changes for this release are included and are in language that non-contributors to the project can understand.
|
||||
To verify this, you can look directly at the commits since the `<last tag>`.
|
||||
|
||||
```
|
||||
git --no-pager log --pretty=oneline "<last tag>..HEAD"
|
||||
```
|
||||
|
||||
- Move all the `Unreleased` changes into a new section following the title scheme (`[<new tag>] - <date of release>`).
|
||||
- Update all the appropriate links at the bottom.
|
||||
|
||||
4. Push the changes to upstream and create a Pull Request on GitHub.
|
||||
Be sure to include the curated changes from the [Changelog](./CHANGELOG.md) in the description.
|
||||
|
||||
|
||||
## Tag
|
||||
|
||||
Once the Pull Request with all the version changes has been approved and merged it is time to tag the merged commit.
|
||||
|
||||
***IMPORTANT***: It is critical you use the same tag that you used in the Pre-Release step!
|
||||
Failure to do so will leave things in a broken state.
|
||||
|
||||
***IMPORTANT***: [There is currently no way to remove an incorrectly tagged version of a Go module](https://github.com/golang/go/issues/34189).
|
||||
It is critical you make sure the version you push upstream is correct.
|
||||
[Failure to do so will lead to minor emergencies and tough to work around](https://github.com/open-telemetry/opentelemetry-go/issues/331).
|
||||
|
||||
1. Run the tag.sh script using the `<commit-hash>` of the commit on the master branch for the merged Pull Request.
|
||||
|
||||
```
|
||||
./tag.sh <new tag> <commit-hash>
|
||||
```
|
||||
|
||||
2. Push tags to the upstream remote (not your fork: `github.com/open-telemetry/opentelemetry-go.git`).
|
||||
Make sure you push all sub-modules as well.
|
||||
|
||||
```
|
||||
git push upstream <new tag>
|
||||
git push upstream <submodules-path/new tag>
|
||||
...
|
||||
```
|
||||
|
||||
## Release
|
||||
|
||||
Finally create a Release for the new `<new tag>` on GitHub.
|
||||
The release body should include all the release notes from the Changelog for this release.
|
||||
Additionally, the `tag.sh` script generates commit logs since last release which can be used to supplement the release notes.
|
||||
|
||||
## Verify Examples
|
||||
|
||||
After releasing verify that examples build outside of the repository.
|
||||
|
||||
```
|
||||
./verify_examples.sh
|
||||
```
|
||||
|
||||
The script copies examples into a different directory removes any `replace` declarations in `go.mod` and builds them.
|
||||
This ensures they build with the published release, not the local copy.
|
||||
|
||||
## Contrib Repository
|
||||
|
||||
Once verified be sure to [make a release for the `contrib` repository](https://github.com/open-telemetry/opentelemetry-go-contrib/blob/master/RELEASING.md) that uses this release.

# Versioning
|
||||
|
||||
This document describes the versioning policy for this repository. This policy
|
||||
is designed so the following goals can be achieved.
|
||||
|
||||
**Users are provided a codebase of value that is stable and secure.**
|
||||
|
||||
## Policy
|
||||
|
||||
* Versioning of this project will be idiomatic of a Go project using [Go
|
||||
modules](https://github.com/golang/go/wiki/Modules).
|
||||
* [Semantic import
|
||||
versioning](https://github.com/golang/go/wiki/Modules#semantic-import-versioning)
|
||||
will be used.
|
||||
* Versions will comply with [semver 2.0](https://semver.org/spec/v2.0.0.html).
|
||||
* If a module is version `v2` or higher, the major version of the module
|
||||
must be included as a `/vN` at the end of the module paths used in
|
||||
`go.mod` files (e.g., `module go.opentelemetry.io/otel/v2`, `require
|
||||
go.opentelemetry.io/otel/v2 v2.0.1`) and in the package import path
|
||||
(e.g., `import "go.opentelemetry.io/otel/v2/trace"`). This includes the
|
||||
paths used in `go get` commands (e.g., `go get
|
||||
go.opentelemetry.io/otel/v2@v2.0.1`. Note there is both a `/v2` and a
|
||||
`@v2.0.1` in that example. One way to think about it is that the module
|
||||
name now includes the `/v2`, so include `/v2` whenever you are using the
|
||||
module name).
|
||||
* If a module is version `v0` or `v1`, do not include the major version in
|
||||
either the module path or the import path.
|
||||
* Modules will be used to encapsulate signals and components.
|
||||
* Experimental modules still under active development will be versioned at
|
||||
`v0` to imply the stability guarantee defined by
|
||||
[semver](https://semver.org/spec/v2.0.0.html#spec-item-4).
|
||||
|
||||
> Major version zero (0.y.z) is for initial development. Anything MAY
|
||||
> change at any time. The public API SHOULD NOT be considered stable.
|
||||
|
||||
* Mature modules for which we guarantee a stable public API will be versioned
|
||||
with a major version greater than `v0`.
|
||||
* The decision to make a module stable will be made on a case-by-case
|
||||
basis by the maintainers of this project.
|
||||
* Experimental modules will start their versioning at `v0.0.0` and will
|
||||
increment their minor version when backwards incompatible changes are
|
||||
released and increment their patch version when backwards compatible
|
||||
changes are released.
|
||||
* All stable modules that use the same major version number will use the
|
||||
same entire version number.
|
||||
* Stable modules may be released with an incremented minor or patch
|
||||
version even though that module has not been changed, but rather so
|
||||
that it will remain at the same version as other stable modules that
|
||||
did undergo change.
|
||||
* When an experimental module becomes stable a new stable module version
|
||||
will be released and will include this now stable module. The new
|
||||
stable module version will be an increment of the minor version number
|
||||
and will be applied to all existing stable modules as well as the newly
|
||||
stable module being released.
|
||||
* Versioning of the associated [contrib
|
||||
repository](https://github.com/open-telemetry/opentelemetry-go-contrib) of
|
||||
this project will be idiomatic of a Go project using [Go
|
||||
modules](https://github.com/golang/go/wiki/Modules).
|
||||
* [Semantic import
|
||||
versioning](https://github.com/golang/go/wiki/Modules#semantic-import-versioning)
|
||||
will be used.
|
||||
* Versions will comply with [semver 2.0](https://semver.org/spec/v2.0.0.html).
|
||||
* If a module is version `v2` or higher, the
|
||||
major version of the module must be included as a `/vN` at the end of the
|
||||
module paths used in `go.mod` files (e.g., `module
|
||||
go.opentelemetry.io/contrib/instrumentation/host/v2`, `require
|
||||
go.opentelemetry.io/contrib/instrumentation/host/v2 v2.0.1`) and in the
|
||||
package import path (e.g., `import
|
||||
"go.opentelemetry.io/contrib/instrumentation/host/v2"`). This includes
|
||||
the paths used in `go get` commands (e.g., `go get
|
||||
go.opentelemetry.io/contrib/instrumentation/host/v2@v2.0.1`. Note there
|
||||
is both a `/v2` and a `@v2.0.1` in that example. One way to think about
|
||||
it is that the module name now includes the `/v2`, so include `/v2`
|
||||
whenever you are using the module name).
|
||||
* If a module is version `v0` or `v1`, do not include the major version
|
||||
in either the module path or the import path.
|
||||
* In addition to public APIs, telemetry produced by stable instrumentation
|
||||
will remain stable and backwards compatible. This is to avoid breaking
|
||||
alerts and dashboard.
|
||||
* Modules will be used to encapsulate instrumentation, detectors, exporters,
|
||||
propagators, and any other independent sets of related components.
|
||||
* Experimental modules still under active development will be versioned at
|
||||
`v0` to imply the stability guarantee defined by
|
||||
[semver](https://semver.org/spec/v2.0.0.html#spec-item-4).
|
||||
|
||||
> Major version zero (0.y.z) is for initial development. Anything MAY
|
||||
> change at any time. The public API SHOULD NOT be considered stable.
|
||||
|
||||
* Mature modules for which we guarantee a stable public API and telemetry will
|
||||
be versioned with a major version greater than `v0`.
|
||||
* Experimental modules will start their versioning at `v0.0.0` and will
|
||||
increment their minor version when backwards incompatible changes are
|
||||
released and increment their patch version when backwards compatible
|
||||
changes are released.
|
||||
* Stable contrib modules cannot depend on experimental modules from this
|
||||
project.
|
||||
* All stable contrib modules of the same major version with this project
|
||||
will use the same entire version as this project.
|
||||
* Stable modules may be released with an incremented minor or patch
|
||||
version even though that module's code has not been changed. Instead
|
||||
the only change that will have been included is to have updated that
|
||||
modules dependency on this project's stable APIs.
|
||||
* When an experimental module in contrib becomes stable a new stable
|
||||
module version will be released and will include this now stable
|
||||
module. The new stable module version will be an increment of the minor
|
||||
version number and will be applied to all existing stable contrib
|
||||
modules, this project's modules, and the newly stable module being
|
||||
released.
|
||||
* Contrib modules will be kept up to date with this project's releases.
|
||||
* Due to the dependency contrib modules will implicitly have on this
|
||||
project's modules the release of stable contrib modules to match the
|
||||
released version number will be staggered after this project's release.
|
||||
There is no explicit time guarantee for how long after this projects
|
||||
release the contrib release will be. Effort should be made to keep them
|
||||
as close in time as possible.
|
||||
* No additional stable release in this project can be made until the
|
||||
contrib repository has a matching stable release.
|
||||
* No release can be made in the contrib repository after this project's
|
||||
stable release except for a stable release of the contrib repository.
|
||||
* GitHub releases will be made for all releases.
|
||||
* Go modules will be made available at Go package mirrors.
|
||||
|
||||
## Example Versioning Lifecycle
|
||||
|
||||
To better understand the implementation of the above policy the following
|
||||
example is provided. This project is simplified to include only the following
|
||||
modules and their versions:
|
||||
|
||||
* `otel`: `v0.14.0`
|
||||
* `otel/trace`: `v0.14.0`
|
||||
* `otel/metric`: `v0.14.0`
|
||||
* `otel/baggage`: `v0.14.0`
|
||||
* `otel/sdk/trace`: `v0.14.0`
|
||||
* `otel/sdk/metric`: `v0.14.0`
|
||||
|
||||
These modules have been developed to a point where the `otel/trace`,
|
||||
`otel/baggage`, and `otel/sdk/trace` modules have reached a point that they
|
||||
should be considered for a stable release. The `otel/metric` and
|
||||
`otel/sdk/metric` are still under active development and the `otel` module
|
||||
depends on both `otel/trace` and `otel/metric`.
|
||||
|
||||
The `otel` package is refactored to remove its dependencies on `otel/metric` so
|
||||
it can be released as stable as well. With that done the following release
|
||||
candidates are made:
|
||||
|
||||
* `otel`: `v1.0.0-rc.1`
|
||||
* `otel/trace`: `v1.0.0-rc.1`
|
||||
* `otel/baggage`: `v1.0.0-rc.1`
|
||||
* `otel/sdk/trace`: `v1.0.0-rc.1`
|
||||
|
||||
The `otel/metric` and `otel/sdk/metric` modules remain at `v0.14.0`.
|
||||
|
||||
A few minor issues are discovered in the `otel/trace` package. These issues are
|
||||
resolved with some minor, but backwards incompatible, changes and are released
|
||||
as a second release candidate:
|
||||
|
||||
* `otel`: `v1.0.0-rc.2`
|
||||
* `otel/trace`: `v1.0.0-rc.2`
|
||||
* `otel/baggage`: `v1.0.0-rc.2`
|
||||
* `otel/sdk/trace`: `v1.0.0-rc.2`
|
||||
|
||||
Notice that all module version numbers are incremented to adhere to our
|
||||
versioning policy.
|
||||
|
||||
After these release candidates have been evaluated to satisfaction, they are
|
||||
released as version `v1.0.0`.
|
||||
|
||||
* `otel`: `v1.0.0`
|
||||
* `otel/trace`: `v1.0.0`
|
||||
* `otel/baggage`: `v1.0.0`
|
||||
* `otel/sdk/trace`: `v1.0.0`
|
||||
|
||||
Since both the `go` utility and the Go module system support [the semantic
|
||||
versioning definition of
|
||||
precedence](https://semver.org/spec/v2.0.0.html#spec-item-11), this release
|
||||
will correctly be interpreted as the successor to the previous release
|
||||
candidates.
|
||||
|
||||
Active development of this project continues. The `otel/metric` module now has
|
||||
backwards incompatible changes to its API that need to be released and the
|
||||
`otel/baggage` module has a minor bug fix that needs to be released. The
|
||||
following release is made:
|
||||
|
||||
* `otel`: `v1.0.1`
|
||||
* `otel/trace`: `v1.0.1`
|
||||
* `otel/metric`: `v0.15.0`
|
||||
* `otel/baggage`: `v1.0.1`
|
||||
* `otel/sdk/trace`: `v1.0.1`
|
||||
* `otel/sdk/metric`: `v0.15.0`
|
||||
|
||||
Notice that, again, all stable module versions are incremented in unison and
|
||||
the `otel/sdk/metric` package, which depends on the `otel/metric` package, also
|
||||
bumped its version. This bump of the `otel/sdk/metric` package makes sense
|
||||
given their coupling, though it is not explicitly required by our versioning
|
||||
policy.
|
||||
|
||||
As we progress, the `otel/metric` and `otel/sdk/metric` packages have reached a
|
||||
point where they should be evaluated for stability. The `otel` module is
|
||||
reintegrated with the `otel/metric` package and the following release is made:
|
||||
|
||||
* `otel`: `v1.1.0-rc.1`
|
||||
* `otel/trace`: `v1.1.0-rc.1`
|
||||
* `otel/metric`: `v1.1.0-rc.1`
|
||||
* `otel/baggage`: `v1.1.0-rc.1`
|
||||
* `otel/sdk/trace`: `v1.1.0-rc.1`
|
||||
* `otel/sdk/metric`: `v1.1.0-rc.1`
|
||||
|
||||
All the modules are evaluated and determined to a viable stable release. They
|
||||
are then released as version `v1.1.0` (the minor version is incremented to
|
||||
indicate the addition of new signal).
|
||||
|
||||
* `otel`: `v1.1.0`
|
||||
* `otel/trace`: `v1.1.0`
|
||||
* `otel/metric`: `v1.1.0`
|
||||
* `otel/baggage`: `v1.1.0`
|
||||
* `otel/sdk/trace`: `v1.1.0`
|
||||
* `otel/sdk/metric`: `v1.1.0`

Package otel provides global access to the OpenTelemetry API. The subpackages of

the otel package provide an implementation of the OpenTelemetry API.

This package is currently in a pre-GA phase. Backwards incompatible changes
|
||||
may be introduced in subsequent minor version releases as we work to track the
|

evolving OpenTelemetry specification and user feedback.
|

|

The provided API is used to instrument code and measure data about that code's
|
||||
performance and operation. The measured data, by default, is not processed or
|

transmitted anywhere. An implementation of the OpenTelemetry SDK, like the
|

default SDK implementation (go.opentelemetry.io/otel/sdk), and associated
|
||||
exporters are used to process and transport this data.

This file contains the forwarding implementation of the TracerProvider used as

the default global instance. Prior to initialization of an SDK, Tracers
|
||||
returned by the global TracerProvider will provide no-op functionality. This
|
||||
means that all Span created prior to initialization are no-op Spans.
|
||||
|
||||
Once an SDK has been initialized, all provided no-op Tracers are swapped for
|
||||
Tracers provided by the SDK defined TracerProvider. However, any Span started
|
||||
prior to this initialization does not change its behavior. Meaning, the Span
|
||||
remains a no-op Span.
|
||||
|
||||
The implementation to track and swap Tracers locks all new Tracer creation
|
||||
until the swap is complete. This assumes that this operation is not
|
||||
performance-critical. If that assumption is incorrect, be sure to configure an

SDK prior to any Tracer creation.
