# 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) with the following exceptions.
|
||
|
|
* New methods may be added to exported API interfaces. All exported
|
||
|
|
interfaces that fall within this exception will include the following
|
||
|
|
paragraph in their public documentation.
|
||
|
|
|
||
|
|
> Warning: methods may be added to this interface in minor releases.
|
||
|
|
|
||
|
|
* 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-RC1`
|
||
|
|
* `otel/trace`: `v1.0.0-RC1`
|
||
|
|
* `otel/baggage`: `v1.0.0-RC1`
|
||
|
|
* `otel/sdk/trace`: `v1.0.0-RC1`
|
||
|
|
|
||
|
|
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-RC2`
|
||
|
|
* `otel/trace`: `v1.0.0-RC2`
|
||
|
|
* `otel/baggage`: `v1.0.0-RC2`
|
||
|
|
* `otel/sdk/trace`: `v1.0.0-RC2`
|
||
|
|
|
||
|
|
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-RC1`
|
||
|
|
* `otel/trace`: `v1.1.0-RC1`
|
||
|
|
* `otel/metric`: `v1.1.0-RC1`
|
||
|
|
* `otel/baggage`: `v1.1.0-RC1`
|
||
|
|
* `otel/sdk/trace`: `v1.1.0-RC1`
|
||
|
|
* `otel/sdk/metric`: `v1.1.0-RC1`
|
||
|
|
|
||
|
|
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`
|
