| # Repository Management Tools | ||
|
|
||
| This Go module is a collection of tools that have been written for managing the AWS SDK for Go V2 source repository. | ||
| At the time these were written, the Go ecosystem lacked tooling for managing repositories containing multiple Go modules | ||
| with at the size and scale of the AWS SDK. With over 274 Go modules in the repository the tooling found here has been | ||
| made to manage the lifecycle of managing dependencies (iter-repository and external), managing the releases of new | ||
| changes, tag management following Go semver requirements, and production of changelogs. | ||
|
|
||
| ## Utilities | ||
| The following is a breakdown of some the key utilities found in this module that are used to manage the SDK and handle | ||
| the complex release process. | ||
|
|
||
| Commands | Description | README | ||
| --- | --- | --- | ||
| `changelog` | Create and manage changelog annotations. Annotations are used to document module changes and refining of the next semver version. | [Link][changelog] | ||
| `updaterequires` | Manages `go.mod` require entries, allows for easily updating inter-repository module dependencies to their latest tag, and the ability to quickly manage external dependency requirements. | N/A | ||
| `updatemodulemeta` | Generates a `go_module_metadata.go` file in each module containing useful runtime metadata like the modules tagged version. | N/A | ||
| `generatechangelog` | Uses a release description and associated changelog annotations to produce `CHANGELOG.md` entries for the release in each repository module. In addition, a summarized release statement will be created at the root of the repository. | N/A | ||
| `gomodgen` | Copies [smithy-go] codegen build artifacts into the SDK repository and generates a `go.mod` file using the build artifacts `generated.json` description. | N/A | ||
| `annotatestablegen` | Generates a release changelog annotation type for **new** [smithy-go] generated modules that are not marked as unstable. | N/A | ||
| `calculaterelease` | Detects new and changed Go modules in the repository, associates changelog annotations, and computes the next semver version tag for each module. Produces a release manifest that is used with other utilities to orchestrate a release. | [Link][calculaterelease] | ||
| `tagrelease` | Commits pending changes to the working directory, reads the release manifest, and creates the computed tags | N/A | ||
| `makerelative` | Used to generate `go.mod` `replace` statements for inter-repository module dependencies. This ensures that when developing on a given Go module it's iter-repository dependencies refer to the cloned repository. | N/A | ||
| `eachmodule` | Utility for quickly scripting execution of commands in each module of a repository. | N/A | ||
|
|
||
| # Configuration | ||
|
|
||
| A number of the repository tools, specifically those involved with the dependency management and release have specific | ||
| behavior that is driven by the `modman.toml` file found at the root of the git repository. This configuration file is | ||
| a [TOML] configuration file. | ||
|
|
||
| ## Dependencies | ||
| The `dependencies` is a dictionary of key-value pairs that describe **external** dependencies that one or more modules | ||
| within the repository may depend on. (External dependencies is defined as the set of Go modules that are not found | ||
| within the project git repository.) This section is used to quickly set the version of a dependency modules in the | ||
| repository should use. The `updaterequires` tool can be used to update all Go modules require statements for each module | ||
| in the repository and update them to the indicated version if they depend on the given external module. | ||
|
|
||
| ### Example | ||
| ```toml | ||
| [dependencies] | ||
| "github.com/aws/smithy-go" = "v1.4.0" | ||
| ``` | ||
|
|
||
| This example indicates that repository modules that depend on `github.com/aws/smithy-go` should depend on `v1.4.0` | ||
| version of the library. After updating the value in the configuration file, `updaterequires` can be used to update | ||
| modules with this information. | ||
|
|
||
| ## Modules | ||
|
|
||
| `modules` is a dictionary where the keys are module directories relative to the repository root. Each key maps to a | ||
| dictionary of key-value pairs that can configure several properties of a module that affect how or | ||
| if a module is handled when performing a release. | ||
|
|
||
| ### Example | ||
| To configure the module `feature/service/shinything` to not be tagged by the release process: | ||
|
|
||
| ```toml | ||
| [modules."feature/service/shinything"] | ||
| no_tag = true | ||
| ``` | ||
|
|
||
| For more information on how to configure how modules are released see the [calculaterelease README][calculaterelease]. | ||

|
||
| **NOTE**: If you wish to create a configuration item for a module located at the root of the repository use | ||
| `.` as the key name. | ||
