const BuildStepsMaxBytes = 1e6

BuildStepsMaxBytes is the maximum length of BuildSteps.Bytes. If Bytes exceeds this maximum, this package will try to compress it, setting IsZipped accordingly, but if this length is still exceeded it's an error to write such entities to the datastore. Use FromProto to ensure this maximum is respected.

BuilderExpirationDuration is the maximum duration a builder can go without having a build scheduled before its BuilderStat may be deleted.

View Source 
const BuilderKind = "Bucket.Builder"

BuilderKind is the kind of the Builder entity.

View Source 
const BuilderStatKind = "Builder"

BuilderStatKind is the kind of the BuilderStat entity.

View Source 
const BuilderStatZombieDuration = 6 * time.Hour

Variables

View Source 
var DefaultBuildMask = HardcodedBuildMask(defaultFieldMask.Paths...)

var GetLimitedBuildMask = HardcodedBuildMask(BuildFieldsWithVisibility(pb.BuildFieldVisibility_BUILDS_GET_LIMITED_PERMISSION)...)

GetLimitedBuildMask is an extra mask to hide fields from callers who have the BuildsGetLimited permission but not BuildsGet. These callers should only be able to see fields specified in this mask.

TagIndexIncomplete means the tag index is incomplete and thus cannot be searched.

Functions

func BucketKey 

func BucketKey(ctx context.Context, project, bucket string) *datastore.Key

BucketKey returns a datastore key of a bucket.

func BuildFieldsWithVisibility 

func BuildFieldsWithVisibility(visibility pb.BuildFieldVisibility) []string

BuildFieldsWithVisibility returns a list of Build fields that are visible with the specified level of read permission. For example, the following: 

BuildFieldsWithVisibility(pb.BuildFieldVisibility_BUILDS_GET_LIMITED_PERMISSION)

[(visible_with) = BUILDS_GET_LIMITED_PERMISSION]
[(visible_with) = BUILDS_LIST_PERMISSION]

Note that visibility permissions are strictly ordered: if a user has the GetLimited permission, that implies they also have the List permission.

func BuilderKey

	Next int32 `gae:"next_number,noindex"`
	// contains filtered or unexported fields
}

NumberSequence stores the next number in a named sequence of numbers.

type Project 

type Project struct {
	ID string `gae:"$id"`

	// CommonConfig is the share config among all buckets and builders in this
	// project.
	CommonConfig *pb.BuildbucketCfg_CommonConfig `gae:"common_config"`
	// contains filtered or unexported fields
}

Project is the parent entity of buckets in the datastore. Entities of this kind may not exist in the datastore if they don't have global_config.

type PropertyChunk 

type PropertyChunk struct {

	// ID starts from 1 to N where N is BuildOutputProperties.ChunkCount.
	ID int `gae:"$id"`
	// The BuildOutputProperties entity that this entity belongs to.
	Parent *datastore.Key `gae:"$parent"`

	// chunked bytes
	Bytes []byte `gae:"chunk,noindex"`
	// contains filtered or unexported fields
}

PropertyChunk stores a chunk of serialized and compressed BuildOutputProperties.Proto bytes. In the future, it may expand to buildInputProperties.

type PubSubCallback 

type PubSubCallback struct {
	AuthToken string `gae:"auth_token,noindex"`
	Topic     string `gae:"topic,noindex"`
	UserData  []byte `gae:"user_data,noindex"`
}

PubSubCallback encapsulates parameters for a Pub/Sub callback.

type RequestID 

type RequestID struct {

	// ID is a string of the form "<auth.Identity>:<request ID string>" encoded
	// as a hex string using SHA-256 for a well-distributed key space.
	ID string `gae:"$id"`

	// BuildID is the ID of the Build entity this entity refers to.
	BuildID    int64             `gae:"build_id,noindex"`
	CreatedBy  identity.Identity `gae:"created_by,noindex"`
	CreateTime time.Time         `gae:"create_time,noindex"`
	// RequestID is the original request ID string this entity was created from.
	RequestID string `gae:"request_id,noindex"`
	// contains filtered or unexported fields
}

RequestID stores request IDs for request deduplication.

func NewRequestID 

func NewRequestID(ctx context.Context, buildID int64, now time.Time, requestID string) *RequestID

NewRequestID returns a request ID with the entity ID filled in.

type TagIndex 

type TagIndex struct {

	// ID is a "<key>:<value>" or ":<index>:<key>:<value>" string for index > 0.
	ID string `gae:"$id"`
	// Incomplete means there are more than MaxTagIndexEntries entities
	// with the same ID, and therefore the index is incomplete and cannot be
	// searched.
	Incomplete bool `gae:"permanently_incomplete,noindex"`
	// Entries is a slice of TagIndexEntries matching this ID.
	Entries []TagIndexEntry `gae:"entries,noindex"`
	// contains filtered or unexported fields
}

TagIndex is an index used to search Build entities by tag.

type TagIndexEntry 

type TagIndexEntry struct {
	// BuildID is the ID of the Build entity this entry refers to.
	BuildID int64 `json:"build_id"`
	// <project>/<bucket>. Bucket is in v2 format.
	// e.g. chromium/try (never chromium/luci.chromium.try).
	BucketID string `json:"bucket_id"`
	// CreatedTime is the time this entry was created.
	CreatedTime time.Time `json:"created_time"`
}

TagIndexEntry refers to a particular Build entity.

func SearchTagIndex 

func SearchTagIndex(ctx context.Context, key, val string) ([]*TagIndexEntry, error)

SearchTagIndex searches the tag index for the given tag. Returns an error tagged with TagIndexIncomplete if the tag index is incomplete and thus cannot be searched.

func (*TagIndexEntry) FromProperty 

func (e *TagIndexEntry) FromProperty(p datastore.Property) error

FromProperty deserializes TagIndexEntries from the datastore. Implements datastore.PropertyConverter.

func (*TagIndexEntry) ToProperty 

func (e *TagIndexEntry) ToProperty() (datastore.Property, error)

ToProperty serializes TagIndexEntries to datastore format. Implements datastore.PropertyConverter.

type UnusedProperties 

type UnusedProperties struct {
	// PubSubCallback is normally a struct (see build.go), which translates into datastore
	// fields pubsub_callback.auth_token, pubsub_callback.topic, pubsub_callback.user_data
	// with no actual field called pubsub_callback. However, nil values in the datastore
	// may exist for pubsub_callback (should instead be represented by having all three
	// pubsub_callback.* fields nil, but isn't). Capture such nil values here.
	// TODO(crbug/1042991): Support this case properly in gae datastore package.
	PubSubCallback []byte `gae:"pubsub_callback,noindex"`
}

UnusedProperties are properties previously set but currently unused.

Notes

Bugs

  • - Setting this to 0 to see if it tamps down suprious Lookup costs in datastore. Should evaluate re-enabling after we turn entity caching back on.
