Types

type IndexTime

type IndexTime struct {
	Field string

	// Asc if true will index with ascending order. Usually you want to
	// find the most recent data so this is false by default.
	Asc bool

func (*State) JobAssignForRunner

func (s *State) JobAssignForRunner(ctx context.Context, r *pb.Runner) (*serverstate.Job, error)

JobAssignForRunner will wait for and assign a job to a specific runner. This will automatically evaluate any conditions that the runner and/or job may have on assignability.

If ctx is provided and assignment has to block waiting for new jobs, this will cancel when the context is done.

func (*State) JobById

func (s *State) JobById(id string, ws memdb.WatchSet) (*serverstate.Job, error)

func (*State) JobComplete

func (s *State) JobComplete(id string, result *pb.Job_Result, cerr error) error

JobComplete marks a running job as complete. If an error is given, the job is marked as failed (a completed state). If no error is given, the job is marked as successful.

func (*State) JobCreate

func (s *State) JobCreate(jobs ...*pb.Job) error

JobCreate queues the given jobs. If any job fails to queue, no jobs are queued. If partial failures are acceptible, call this multiple times with a single job.

func (*State) JobExpire

func (s *State) JobExpire(id string) error

JobExpire expires a job. This will cancel the job if it is still queued.

func (*State) JobHeartbeat

func (s *State) JobHeartbeat(id string) error

JobHeartbeat resets the heartbeat timer for a running job. If the job is not currently running this does nothing, it will not return an error. If the job doesn't exist then this will return an error.

func (*State) JobIsAssignable

func (s *State) JobIsAssignable(ctx context.Context, jobpb *pb.Job) (bool, error)

JobIsAssignable returns whether there is a registered runner that meets the requirements to run this job.

If this returns true, the job if queued should eventually be assigned successfully to a runner. An assignable result does NOT mean that it will be in queue a short amount of time.

Note the result is a point-in-time result. If the only candidate runners deregister between this returning true and queueing, the job may still sit in a queue indefinitely.

func (*State) JobList

func (s *State) JobList() ([]*pb.Job, error)

JobList returns the list of jobs.

func (*State) JobPeekForRunner added in v0.6.0

func (s *State) JobPeekForRunner(ctx context.Context, r *pb.Runner) (*serverstate.Job, error)

func (*State) JobProjectScopedRequest added in v0.7.0

func (s *State) JobProjectScopedRequest(
	pRef *pb.Ref_Project,
	jobTemplate *pb.Job,
) ([]*pb.QueueJobRequest, error)

func (s *State) JobUpdate(id string, cb func(jobpb *pb.Job) error) error

JobUpdate calls the given callback to update fields on the job data. The callback is called in the context of a database write lock so it should NOT compute anything and should be fast. The callback can return an error to abort the transaction.

Job states should NOT be modified using this, only metadata.

func (*State) JobUpdateRef added in v0.3.0

func (s *State) JobUpdateRef(id string, ref *pb.Job_DataSource_Ref) error

func (*State) ProjectPollPeek added in v0.3.0

func (s *State) ProjectPollPeek(ws memdb.WatchSet) (*pb.Project, time.Time, error)

ProjectPollPeek returns the next project that should be polled. This will return (nil,nil) if there are no projects to poll currently.

This is a "peek" operation so it does not update the project's next poll time. Therefore, calling this multiple times should return the same result unless a function like ProjectPollComplete is called.

If ws is non-nil, the WatchSet can be watched for any changes to projects to poll. This can be watched, for example, to detect when projects to poll are added. This is important functionality since callers may be sleeping on a deadline for awhile when a new project is inserted to poll immediately.
