Documentation

Overview

The index service is responsible for indexing tasks. The service ensures that tasks can be located by user-defined names.

As described in the service documentation, tasks are typically indexed via Pulse messages, so the most common use of API methods is to read from the index.

See:

How to use this package

First create an Index object: 

index := tcindex.New(nil)

and then call one or more of index's methods, e.g.: 

err := index.Ping(.....)

handling any errors... 

if err != nil {
	// handle error...
}

Taskcluster Schema

The source code of this go package was auto-generated from the API definition at https://community-tc.services.mozilla.com/references/index/v1/api.json together with the input and output schemas it references, downloaded on Thu, 31 Oct 2019 at 18:23:00 UTC.

Types

type Index 

type Index tcclient.Client

func New 

func New(credentials *tcclient.Credentials, rootURL string) *Index

New returns an Index client, configured to run against production. Pass in nil credentials to create a client without authentication. The returned client is mutable, so returned settings can be altered. 

index := tcindex.New(
    nil,                                      // client without authentication
    "http://localhost:1234/my/taskcluster",   // taskcluster hosted at this root URL on local machine
)
err := index.Ping(.....)                      // for example, call the Ping(.....) API endpoint (described further down)...
if err != nil {
	// handle errors...
}

func NewFromEnv 

func NewFromEnv() *Index

NewFromEnv returns an *Index configured from environment variables.

The root URL is taken from TASKCLUSTER_PROXY_URL if set to a non-empty string, otherwise from TASKCLUSTER_ROOT_URL if set, otherwise the empty string.

The credentials are taken from environment variables: 

TASKCLUSTER_CLIENT_ID
TASKCLUSTER_ACCESS_TOKEN
TASKCLUSTER_CERTIFICATE

If TASKCLUSTER_CLIENT_ID is empty/unset, authentication will be disabled.

func (*Index) FindArtifactFromTask 

func (index *Index) FindArtifactFromTask(indexPath, name string) error

Find a task by index path and redirect to the artifact on the most recent run with the given `name`.

Note that multiple calls to this endpoint may return artifacts from differen tasks if a new task is inserted into the index between calls. Avoid using this method as a stable link to multiple, connected files if the index path does not contain a unique identifier. For example, the following two links may return unrelated files: * https://tc.example.com/api/index/v1/task/some-app.win64.latest.installer/artifacts/public/installer.exe` * https://tc.example.com/api/index/v1/task/some-app.win64.latest.installer/artifacts/public/debug-symbols.zip`

This problem be remedied by including the revision in the index path or by bundling both installer and debug symbols into a single artifact.

If no task exists for the given index path, this API end-point responds with 404.

Required scopes: 

If private:
  queue:get-artifact:<name>

See #findArtifactFromTask

func (*Index) FindArtifactFromTask_SignedURL 

func (index *Index) FindArtifactFromTask_SignedURL(indexPath, name string, duration time.Duration) (*url.URL, error)

Returns a signed URL for FindArtifactFromTask, valid for the specified duration.

Required scopes: 

If private:
  queue:get-artifact:<name>

See FindArtifactFromTask for more details.

func (*Index) FindTask 

func (index *Index) FindTask(indexPath string) (*IndexedTaskResponse, error)

Find a task by index path, returning the highest-rank task with that path. If no task exists for the given path, this API end-point will respond with a 404 status.

See #findTask

func (*Index) InsertTask 

func (index *Index) InsertTask(namespace string, payload *InsertTaskRequest) (*IndexedTaskResponse, error)

Insert a task into the index. If the new rank is less than the existing rank at the given index path, the task is not indexed but the response is still 200 OK.

Please see the introduction above for information about indexing successfully completed tasks automatically using custom routes.

Required scopes: 

index:insert-task:<namespace>

See #insertTask

func (*Index) ListNamespaces 

func (index *Index) ListNamespaces(namespace, continuationToken, limit string) (*ListNamespacesResponse, error)

List the namespaces immediately under a given namespace.

This endpoint lists up to 1000 namespaces. If more namespaces are present, a `continuationToken` will be returned, which can be given in the next request. For the initial request, the payload should be an empty JSON object.

See #listNamespaces

func (*Index) ListTasks 

func (index *Index) ListTasks(namespace, continuationToken, limit string) (*ListTasksResponse, error)

List the tasks immediately under a given namespace.

This endpoint lists up to 1000 tasks. If more tasks are present, a `continuationToken` will be returned, which can be given in the next request. For the initial request, the payload should be an empty JSON object.

**Remark**, this end-point is designed for humans browsing for tasks, not services, as that makes little sense.

See #listTasks

func (*Index) Ping 

func (index *Index) Ping() error

Respond without doing anything. This endpoint is used to check that the service is up.

See #ping
