It provides +both synchronous and asynchronous interfaces for all Taskcluster API methods, +in both Python-2 and Python-3 variants. + +## Usage + +For a general guide to using Taskcluster clients, see [Calling Taskcluster APIs](https://docs.taskcluster.net/docs/manual/using/api). + +### Setup + +Before calling an API end-point, you'll need to create a client instance. +There is a class for each service, e.g., `Queue` and `Auth`. Each takes the +same options, described below. Note that only `rootUrl` is +required, and it's unusual to configure any other options aside from +`credentials`. + +For each service, there are sync and async variants. The classes under +`taskcluster` (e.g., `taskcluster.Queue`) are Python-2 compatible and operate +synchronously. The classes under `taskcluster.aio` (e.g., +`taskcluster.aio.Queue`) require Python >= 3.6. + +#### Authentication Options + +Here is a simple set-up of an Index client: + +```python +import taskcluster +index = taskcluster.Index({ + 'rootUrl': 'https://tc.example.com', + 'credentials': {'clientId': 'id', 'accessToken': 'accessToken'}, +}) +``` + +The `rootUrl` option is required as it gives the Taskcluster deployment to +which API requests should be sent. Credentials are only required if the +request is to be authenticated -- many Taskcluster API methods do not require +authentication. + +In most cases, the root URL and Taskcluster credentials should be provided in [standard environment variables](https://docs.taskcluster.net/docs/manual/design/env-vars). Use `taskcluster.optionsFromEnvironment()` to read these variables automatically: + +```python +auth = taskcluster.Auth(taskcluster.optionsFromEnvironment()) +``` + +Note that this function does not respect `TASKCLUSTER_PROXY_URL`. To use the Taskcluster Proxy from within a task: + +```python +auth = taskcluster.Auth({'rootUrl': os.environ['TASKCLUSTER_PROXY_URL']}) +``` + +#### Authorized Scopes + +If you wish to perform requests on behalf of a third-party that has small set +of scopes than you do. You can specify [which scopes your request should be +allowed to +use](https://docs.taskcluster.net/docs/manual/design/apis/hawk/authorized-scopes), +in the `authorizedScopes` option. + +```python +opts = taskcluster.optionsFromEnvironment() +opts['authorizedScopes'] = ['queue:create-task:highest:my-provisioner/my-worker-type'] +queue = taskcluster.Queue(opts) +``` + +#### Other Options + +The following additional options are accepted when constructing a client object: + +* `signedUrlExpiration` - default value for the `expiration` argument to `buildSignedUrl` +* `maxRetries` - maximum number of times to retry a failed request + +### Calling API Methods + +API methods are available as methods on the corresponding client object. For +sync clients, these are sync methods, and for async clients they are async +methods; the calling convention is the same in either case. + +There are four calling conventions for methods: + +```python +client.method(v1, v1, payload) +client.method(payload, k1=v1, k2=v2) +client.method(payload=payload, query=query, params={k1: v1, k2: v2}) +client.method(v1, v2, payload=payload, query=query) +``` + +Here, `v1` and `v2` are URL parameters (named `k1` and `k2`), `payload` is the +request payload, and `query` is a dictionary of query arguments. + +For example, in order to call an API method with query-string arguments: + +```python +await queue.listTaskGroup('JzTGxwxhQ76_Tt1dxkaG5g', + query={'continuationToken': previousResponse.get('continuationToken')}) +``` + + +### Generating URLs + +It is often necessary to generate the URL for an API method without actually calling the method. +To do so, use `buildUrl` or, for an API method that requires authentication, `buildSignedUrl`. + +```python +import taskcluster + +index = taskcluster.Index(taskcluster.optionsFromEnvironment()) +print(index.buildUrl('findTask', 'builds.v1.latest')) +secrets = taskcluster.Secrets(taskcluster.optionsFromEnvironment()) +print(secret.buildSignedUrl('get', 'my-secret')) +``` + +Note that signed URLs are time-limited; the expiration can be set with the `signedUrlExpiration` option to the client constructor, or with the `expiration` keyword arguement to `buildSignedUrl`, both given in seconds. + +### Generating Temporary Credentials + +If you have non-temporary taskcluster credentials you can generate a set of +[temporary credentials](https://docs.taskcluster.net/docs/manual/design/apis/hawk/temporary-credentials) as follows. Notice that the credentials cannot last more +than 31 days, and you can only revoke them by revoking the credentials that was +used to issue them (this takes up to one hour). + +It is not the responsibility of the caller to apply any clock drift adjustment +to the start or expiry time - this is handled by the auth service directly. + +```python +import datetime + +start = datetime.datetime.now() +expiry = start + datetime.timedelta(0,60) +scopes = ['ScopeA', 'ScopeB'] +name = 'foo' + +credentials = taskcluster.createTemporaryCredentials( + # issuing clientId + clientId, + # issuing accessToken + accessToken, + # Validity of temporary credentials starts here, in timestamp + start, + # Expiration of temporary credentials, in timestamp + expiry, + # Scopes to grant the temporary credentials + scopes, + # credential name (optional) + name +) +``` + +You cannot use temporary credentials to issue new temporary credentials. You +must have `auth:create-client:<name>` to create a named temporary credential, +but unnamed temporary credentials can be created regardless of your scopes. + +### Handling Timestamps +Many taskcluster APIs require ISO 8601 time stamps offset into the future +as way of providing expiration, deadlines, etc. These can be easily created +using `datetime.datetime.isoformat()`, however, it can be rather error prone +and tedious to offset `datetime.datetime` objects into the future. Therefore +this library comes with two utility functions for this purposes. + +```python +dateObject = taskcluster.fromNow("2 days 3 hours 1 minute") + # -> datetime.datetime(2017, 1, 21, 17, 8, 1, 607929) +dateString = taskcluster.fromNowJSON("2 days 3 hours 1 minute") + # -> '2017-01-21T17:09:23.240178Z' +``` + +By default it will offset the date time into the future, if the offset strings +are prefixed minus (`-`) the date object will be offset into the past. This is +useful in some corner cases. + +```python +dateObject = taskcluster.fromNow("- 1 year 2 months 3 weeks 5 seconds"); + # -> datetime.datetime(2015, 10, 30, 18, 16, 50, 931161) +``` + +The offset string is ignorant of whitespace and case insensitive. It may also +optionally be prefixed plus `+` (if not prefixed minus), any `+` prefix will be +ignored. However, entries in the offset string must be given in order from +high to low, ie. `2 years 1 day`. Additionally, various shorthands may be +employed, as illustrated below. + +``` + years, year, yr, y + months, month, mo + weeks, week, w + days, day, d + hours, hour, h + minutes, minute, min + seconds, second, sec, s +``` + +The `fromNow` method may also be given a date to be relative to as a second +argument. This is useful if offset the task expiration relative to the the task +deadline or doing something similar. This argument can also be passed as the +kwarg `dateObj` + +```python +dateObject1 = taskcluster.fromNow("2 days 3 hours"); +dateObject2 = taskcluster.fromNow("1 year", dateObject1); +taskcluster.fromNow("1 year", dateObj=dateObject1); + # -> datetime.datetime(2018, 1, 21, 17, 59, 0, 328934) +``` +### Generating SlugIDs + +To generate slugIds (Taskcluster's client-generated unique IDs), use +`taskcluster.slugId()`, which will return a unique slugId on each call. + +In some cases it is useful to be able to create a mapping from names to +slugIds, with the ability to generate the same slugId multiple times. +The `taskcluster.stableSlugId()` function returns a callable that does +just this. + +```python +gen = taskcluster.stableSlugId() +sometask = gen('sometask') +assert gen('sometask') == sometask # same input generates same output +assert gen('sometask') != gen('othertask') + +gen2 = taskcluster.stableSlugId() +sometask2 = gen('sometask') +assert sometask2 != sometask # but different slugId generators produce + # different output +``` + +### Scope Analysis + +The `scopeMatch(assumedScopes, requiredScopeSets)` function determines +whether one or more of a set of required scopes are satisfied by the assumed +scopes, taking *-expansion into account. This is useful for making local +decisions on scope satisfaction, but note that `assumed_scopes` must be the +*expanded* scopes, as this function cannot perform expansion. + +It takes a list of a assumed scopes, and a list of required scope sets on +disjunctive normal form, and checks if any of the required scope sets are +satisfied. + +Example: + +```python +requiredScopeSets = [ + ["scopeA", "scopeB"], + ["scopeC:*"] +] +assert scopesMatch(['scopeA', 'scopeB'], requiredScopeSets) +assert scopesMatch(['scopeC:xyz'], requiredScopeSets) +assert not scopesMatch(['scopeA'], requiredScopeSets) +assert not scopesMatch(['scopeC'], requiredScopeSets) +``` + +### Pagination + +Many Taskcluster API methods are paginated. There are two ways to handle +pagination easily with the python client. The first is to implement pagination +in your code: + +```python +import taskcluster +queue = taskcluster.Queue({'rootUrl': 'https://tc.example.com'}) +i = 0 +tasks = 0 +outcome = queue.listTaskGroup('JzTGxwxhQ76_Tt1dxkaG5g') +while outcome.get('continuationToken'): + print('Response %d gave us %d more tasks' % (i, len(outcome['tasks']))) + if outcome.get('continuationToken'): + outcome = queue.listTaskGroup('JzTGxwxhQ76_Tt1dxkaG5g', query={'continuationToken': outcome.get('continuationToken')}) + i += 1 + tasks += len(outcome.get('tasks', [])) +print('Task Group %s has %d tasks' % (outcome['taskGroupId'], tasks)) +``` + +There's also an experimental feature to support built in automatic pagination +in the sync client. This feature allows passing a callback as the +'paginationHandler' keyword-argument. This function will be passed the +response body of the API method as its sole positional arugment. + +This example of the built in pagination shows how a list of tasks could be +built and then counted: + +```python +import taskcluster +queue = taskcluster.Queue({'rootUrl': 'https://tc.example.com'}) + +responses = [] + +def handle_page(y): + print("%d tasks fetched" % len(y.get('tasks', []))) + responses.append(y) + +queue.listTaskGroup('JzTGxwxhQ76_Tt1dxkaG5g', paginationHandler=handle_page) + +tasks = 0 +for response in responses: + tasks += len(response.get('tasks', [])) + +print("%d requests fetch %d tasks" % (len(responses), tasks)) +``` + +### Pulse Events + +This library can generate exchange patterns for Pulse messages based on the +Exchanges definitions provded by each service. This is done by instantiating a +`<service>Events` class and calling a method with the name of the vent. +Options for the topic exchange methods can be in the form of either a single +dictionary argument or keyword arguments. Only one form is allowed. + +```python +from taskcluster import client +qEvt = client.QueueEvents({rootUrl: 'https://tc.example.com'}) +# The following calls are equivalent +print(qEvt.taskCompleted({'taskId': 'atask'})) +print(qEvt.taskCompleted(taskId='atask')) +``` + +Note that the client library does *not* provide support for interfacing with a Pulse server. + +### Logging + +Logging is set up in `taskcluster/__init__.py`. If the special +`DEBUG_TASKCLUSTER_CLIENT` environment variable is set, the `__init__.py` +module will set the `logging` module's level for its logger to `logging.DEBUG` +and if there are no existing handlers, add a `logging.StreamHandler()` +instance. This is meant to assist those who do not wish to bother figuring out +how to configure the python logging module but do want debug messages + +## Uploading and Downloading Objects + +The Object service provides an API for reliable uploads and downloads of large objects. +This library provides convenience methods to implement the client portion of those APIs, providing well-tested, resilient upload and download functionality. +These methods will negotiate the appropriate method with the object service and perform the required steps to transfer the data. + +All methods are available in both sync and async versions, with identical APIs except for the `async`/`await` keywords. +These methods are not available for Python-2.7. + +In either case, you will need to provide a configured `Object` instance with appropriate credentials for the operation. + +NOTE: There is an helper function to upload `s3` artifacts, `taskcluster.helper.upload_artifact`, but it is deprecated as it only supports the `s3` artifact type. + +### Uploads + +To upload, use any of the following: + +* `await taskcluster.aio.upload.uploadFromBuf(projectId=.., name=.., contentType=.., contentLength=.., uploadId=.., expires=.., maxRetries=.., objectService=.., data=..)` - asynchronously upload data from a buffer full of bytes. +* `await taskcluster.aio.upload.uploadFromFile(projectId=.., name=.., contentType=.., contentLength=.., uploadId=.., expires=.., maxRetries=.., objectService=.., file=..)` - asynchronously upload data from a standard Python file. + Note that this is [probably what you want](https://github.com/python/asyncio/wiki/ThirdParty#filesystem), even in an async context. +* `await taskcluster.aio.upload(projectId=.., name=.., contentType=.., contentLength=.., expires=.., uploadId=.., maxRetries=.., objectService=.., readerFactory=..)` - asynchronously upload data from an async reader factory. +* `taskcluster.upload.uploadFromBuf(projectId=.., name=.., contentType=.., contentLength=.., expires=.., uploadId=.., maxRetries=.., objectService=.., data=..)` - upload data from a buffer full of bytes. +* `taskcluster.upload.uploadFromFile(projectId=.., name=.., contentType=.., contentLength=.., expires=.., uploadId=.., maxRetries=.., objectService=.., file=..)` - upload data from a standard Python file. +* `taskcluster.upload(projectId=.., name=.., contentType=.., contentLength=.., expires=.., uploadId=.., maxRetries=.., objectService=.., readerFactory=..)` - upload data from a sync reader factory. + +A "reader" is an object with a `read(max_size=-1)` method which reads and returns a chunk of 1 .. `max_size` bytes, or returns an empty string at EOF, async for the async functions and sync for the remainder. +A "reader factory" is an async callable which returns a fresh reader, ready to read the first byte of the object. +When uploads are retried, the reader factory may be called more than once. + +The `uploadId` parameter may be omitted, in which case a new slugId will be generated. + +### Downloads + +To download, use any of the following: + +* `await taskcluster.aio.download.downloadToBuf(name=.., maxRetries=.., objectService=..)` - asynchronously download an object to an in-memory buffer, returning a tuple (buffer, content-type). + If the file is larger than available memory, this will crash. +* `await taskcluster.aio.download.downloadToFile(name=.., maxRetries=.., objectService=.., file=..)` - asynchronously download an object to a standard Python file, returning the content type. +* `await taskcluster.aio.download.download(name=.., maxRetries=.., objectService=.., writerFactory=..)` - asynchronously download an object to an async writer factory, returning the content type. +* `taskcluster.download.downloadToBuf(name=.., maxRetries=.., objectService=..)` - download an object to an in-memory buffer, returning a tuple (buffer, content-type). + If the file is larger than available memory, this will crash. +* `taskcluster.download.downloadToFile(name=.., maxRetries=.., objectService=.., file=..)` - download an object to a standard Python file, returning the content type. +* `taskcluster.download.download(name=.., maxRetries=.., objectService=.., writerFactory=..)` - download an object to a sync writer factory, returning the content type. + +A "writer" is an object with a `write(data)` method which writes the given data, async for the async functions and sync for the remainder. +A "writer factory" is a callable (again either async or sync) which returns a fresh writer, ready to write the first byte of the object. +When uploads are retried, the writer factory may be called more than once. + +### Artifact Downloads + +Artifacts can be downloaded from the queue service with similar functions to those above. +These functions support all of the queue's storage types, raising an error for `error` artifacts. +In each case, if `runId` is omitted then the most recent run will be used. + +* `await taskcluster.aio.download.downloadArtifactToBuf(taskId=.., runId=.., name=.., maxRetries=.., queueService=..)` - asynchronously download an object to an in-memory buffer, returning a tuple (buffer, content-type). + If the file is larger than available memory, this will crash. +* `await taskcluster.aio.download.downloadArtifactToFile(taskId=.., runId=.., name=.., maxRetries=.., queueService=.., file=..)` - asynchronously download an object to a standard Python file, returning the content type. +* `await taskcluster.aio.download.downloadArtifact(taskId=.., runId=.., name=.., maxRetries=.., queueService=.., writerFactory=..)` - asynchronously download an object to an async writer factory, returning the content type. +* `taskcluster.download.downloadArtifactToBuf(taskId=.., runId=.., name=.., maxRetries=.., queueService=..)` - download an object to an in-memory buffer, returning a tuple (buffer, content-type). + If the file is larger than available memory, this will crash. +* `taskcluster.download.downloadArtifactToFile(taskId=.., runId=.., name=.., maxRetries=.., queueService=.., file=..)` - download an object to a standard Python file, returning the content type. +* `taskcluster.download.downloadArtifact(taskId=.., runId=.., name=.., maxRetries=.., queueService=.., writerFactory=..)` - download an object to a sync writer factory, returning the content type. + +## Integration Helpers + +The Python Taskcluster client has a module `taskcluster.helper` with utilities which allows you to easily share authentication options across multiple services in your project. + +Generally a project using this library will face different use cases and authentication options: + +* No authentication for a new contributor without Taskcluster access, +* Specific client credentials through environment variables on a developer's computer, +* Taskcluster Proxy when running inside a task. + +### Shared authentication + +The class `taskcluster.helper.TaskclusterConfig` is made to be instantiated once in your project, usually in a top level module. That singleton is then accessed by different parts of your projects, whenever a Taskcluster service is needed. + +Here is a sample usage: + +1. in `project/__init__.py`, no call to Taskcluster is made at that point: + +```python +from taskcluster.helper import Taskcluster config + +tc = TaskclusterConfig('https://community-tc.services.mozilla.com') +``` + +2. in `project/boot.py`, we authenticate on Taskcuster with provided credentials, or environment variables, or taskcluster proxy (in that order): + +```python +from project import tc + +tc.auth(client_id='XXX', access_token='YYY') +``` + +3. at that point, you can load any service using the authenticated wrapper from anywhere in your code: + +```python +from project import tc + +def sync_usage(): + queue = tc.get_service('queue') + queue.ping() + +async def async_usage(): + hooks = tc.get_service('hooks', use_async=True) # Asynchronous service class + await hooks.ping() +``` + +Supported environment variables are: +- `TASKCLUSTER_ROOT_URL` to specify your Taskcluster instance base url. You can either use that variable or instanciate `TaskclusterConfig` with the base url. +- `TASKCLUSTER_CLIENT_ID` & `TASKCLUSTER_ACCESS_TOKEN` to specify your client credentials instead of providing them to `TaskclusterConfig.auth` +- `TASKCLUSTER_PROXY_URL` to specify the proxy address used to reach Taskcluster in a task. It defaults to `http://taskcluster` when not specified. + +For more details on Taskcluster environment variables, [here is the documentation](https://docs.taskcluster.net/docs/manual/design/env-vars). + +### Loading secrets across multiple authentications + +Another available utility is `taskcluster.helper.load_secrets` which allows you to retrieve a secret using an authenticated `taskcluster.Secrets` instance (using `TaskclusterConfig.get_service` or the synchronous class directly). + +This utility loads a secret, but allows you to: +1. share a secret across multiple projects, by using key prefixes inside the secret, +2. check that some required keys are present in the secret, +3. provide some default values, +4. provide a local secret source instead of using the Taskcluster service (useful for local development or sharing _secrets_ with contributors) + +Let's say you have a secret on a Taskcluster instance named `project/foo/prod-config`, which is needed by a backend and some tasks. Here is its content: + +```yaml +common: + environment: production + remote_log: https://log.xx.com/payload + +backend: + bugzilla_token: XXXX + +task: + backend_url: https://backend.foo.mozilla.com +``` + +In your backend, you would do: + +```python +from taskcluster import Secrets +from taskcluster.helper import load_secrets + +prod_config = load_secrets( + Secrets({...}), + 'project/foo/prod-config', + + # We only need the common & backend parts + prefixes=['common', 'backend'], + + # We absolutely need a bugzilla token to run + required=['bugzilla_token'], + + # Let's provide some default value for the environment + existing={ + 'environment': 'dev', + } +) + # -> prod_config == { + # "environment": "production" + # "remote_log": "https://log.xx.com/payload", + # "bugzilla_token": "XXXX", + # } +``` + +In your task, you could do the following using `TaskclusterConfig` mentionned above (the class has a shortcut to use an authenticated `Secrets` service automatically): + +```python +from project import tc + +prod_config = tc.load_secrets( + 'project/foo/prod-config', + + # We only need the common & bot parts + prefixes=['common', 'bot'], + + # Let's provide some default value for the environment and backend_url + existing={ + 'environment': 'dev', + 'backend_url': 'http://localhost:8000', + } +) + # -> prod_config == { + # "environment": "production" + # "remote_log": "https://log.xx.com/payload", + # "backend_url": "https://backend.foo.mozilla.com", + # } +``` + +To provide local secrets value, you first need to load these values as a dictionary (usually by reading a local file in your format of choice : YAML, JSON, ...) and providing the dictionary to `load_secrets` by using the `local_secrets` parameter: + +```python +import os +import yaml + +from taskcluster import Secrets +from taskcluster.helper import load_secrets + +local_path = 'path/to/file.yml' + +prod_config = load_secrets( + Secrets({...}), + 'project/foo/prod-config', + + # We support an optional local file to provide some configuration without reaching Taskcluster + local_secrets=yaml.safe_load(open(local_path)) if os.path.exists(local_path) else None, +) +``` + +## Compatibility + +This library is co-versioned with Taskcluster itself. +That is, a client with version x.y.z contains API methods corresponding to Taskcluster version x.y.z. +Taskcluster is careful to maintain API compatibility, and guarantees it within a major version. +That means that any client with version x.* will work against any Taskcluster services at version x.*, and is very likely to work for many other major versions of the Taskcluster services. +Any incompatibilities are noted in the [Changelog](https://github.com/taskcluster/taskcluster/blob/main/CHANGELOG.md). + + + + + + |
