// This API end-point creates an artifact for a specific run of a task. This

//
// All artifacts must specify when they `expires`, the queue will
// automatically take care of deleting artifacts past their
// expiration point. This features makes it feasible to upload large
// intermediate artifacts from data processing applications, as the
// artifacts can be set to expire a few days later.
//
// We currently support "S3 Artifacts" officially, with remaining support
// for two deprecated types.  Do not use these deprecated types.
//
// **S3 artifacts**, is useful for static files which will be
// stored on S3. When creating an S3 artifact the queue will return a
// pre-signed URL to which you can do a `PUT` request to upload your
// artifact. Note that `PUT` request **must** specify the `content-length`
// header and **must** give the `content-type` header the same value as in
// the request to `createArtifact`.
//
// **Reference artifacts**, only consists of meta-data which the queue will
// store for you. These artifacts really only have a `url` property and
// when the artifact is requested the client will be redirect the URL
// provided with a `303` (See Other) redirect. Please note that we cannot
// delete artifacts you upload to other service, we can only delete the
// reference to the artifact, when it expires.
//
// **Error artifacts**, only consists of meta-data which the queue will
// store for you. These artifacts are only meant to indicate that you the
// worker or the task failed to generate a specific artifact, that you
// would otherwise have uploaded. For example docker-worker will upload an
// error artifact, if the file it was supposed to upload doesn't exists or
// turns out to be a directory. Clients requesting an error artifact will
// get a `424` (Failed Dependency) response. This is mainly designed to
// ensure that dependent tasks can distinguish between artifacts that were
// suppose to be generated and artifacts for which the name is misspelled.
//
// **Artifact immutability**, generally speaking you cannot overwrite an
// artifact when created. But if you repeat the request with the same
// properties the request will succeed as the operation is idempotent.
// This is useful if you need to refresh a signed URL while uploading.
// Do not abuse this to overwrite artifacts created by another entity!
// Such as worker-host overwriting artifact created by worker-code.
//
// As a special case the `url` property on _reference artifacts_ can be
// updated. You should only use this to update the `url` property for
// reference artifacts your process has created.

// browser, without using Taskcluster credentials, include a scope in the

// `queue:get-artifact:public/*`.
//
// **API Clients**, this method will redirect you to the artifact, if it is
// stored externally. Either way, the response may not be JSON. So API
// client users might want to generate a signed URL for this end-point and
// use that URL with an HTTP client that can handle responses correctly.
//
// **Downloading artifacts**
// There are some special considerations for those http clients which download
// artifacts.  This api endpoint is designed to be compatible with an HTTP 1.1
// compliant client, but has extra features to ensure the download is valid.
// It is strongly recommend that consumers use either taskcluster-lib-artifact (JS),
// taskcluster-lib-artifact-go (Go) or the CLI written in Go to interact with
// artifacts.
//
// In order to download an artifact the following must be done:
//
// 1. Obtain queue url.  Building a signed url with a taskcluster client is
// recommended
// 1. Make a GET request which does not follow redirects
// 1. In all cases, if specified, the
// x-taskcluster-location-{content,transfer}-{sha256,length} values must be
// validated to be equal to the Content-Length and Sha256 checksum of the
// final artifact downloaded. as well as any intermediate redirects
// 1. If this response is a 500-series error, retry using an exponential
// backoff.  No more than 5 retries should be attempted
// 1. If this response is a 400-series error, treat it appropriately for
// your context.  This might be an error in responding to this request or
// an Error storage type body.  This request should not be retried.
// 1. If this response is a 200-series response, the response body is the artifact.
// If the x-taskcluster-location-{content,transfer}-{sha256,length} and
// x-taskcluster-location-content-encoding are specified, they should match
// this response body
// 1. If the response type is a 300-series redirect, the artifact will be at the
// location specified by the `Location` header.  There are multiple artifact storage
// types which use a 300-series redirect.
// 1. For all redirects followed, the user must verify that the content-sha256, content-length,
// transfer-sha256, transfer-length and content-encoding match every further request.  The final
// artifact must also be validated against the values specified in the original queue response
// 1. Caching of requests with an x-taskcluster-artifact-storage-type value of `reference`
// must not occur
//
// **Headers**
// The following important headers are set on the response to this method:
//
// * location: the url of the artifact if a redirect is to be performed
// * x-taskcluster-artifact-storage-type: the storage type.  Example: s3
//
// The following important headers are set on responses to this method for Blob artifacts
//
// * x-taskcluster-location-content-sha256: the SHA256 of the artifact
// *after* any content-encoding is undone.  Sha256 is hex encoded (e.g. [0-9A-Fa-f]{64})
// * x-taskcluster-location-content-length: the number of bytes *after* any content-encoding
// is undone
// * x-taskcluster-location-transfer-sha256: the SHA256 of the artifact
// *before* any content-encoding is undone.  This is the SHA256 of what is sent over
// the wire.  Sha256 is hex encoded (e.g. [0-9A-Fa-f]{64})
// * x-taskcluster-location-transfer-length: the number of bytes *after* any content-encoding
// is undone
// * x-taskcluster-location-content-encoding: the content-encoding used.  It will either
// be `gzip` or `identity` right now.  This is hardcoded to a value set when the artifact
// was created and no content-negotiation occurs
// * x-taskcluster-location-content-type: the content-type of the artifact
//
// **Caching**, artifacts may be cached in data centers closer to the
// workers in-order to reduce bandwidth costs. This can lead to longer
// response times. Caching can be skipped by setting the header
// `x-taskcluster-skip-cache: true`, this should only be used for resources
// where request volume is known to be low, and caching not useful.
// (This feature may be disabled in the future, use is sparingly!)
