Types

type BisectExecution 

type BisectExecution struct {
	JobId string
	// TODO(b/322203189): replace Culprits with DetailedCulprits. This field is used by the
	// catapult bisect UI write.
	Culprits []*pinpoint_proto.CombinedCommit
	// DetailedCulprits stores a list of culprits and the commit prior to the culprit.
	// Without this field, culprit verification would not know the commit prior to any culprit
	// and be unable to verify the correct pair of commits.
	DetailedCulprits []*pinpoint_proto.Culprit
	CreateTime       *timestamppb.Timestamp
	Comparisons      []*CombinedResults
	RunData          []*BisectRun
}

BisectExecution is a mirror of pinpoint_proto.BisectExecution, with additional raw data.

When this BisectExecution embeds pinpoint_proto.BisectExecution, it fails to store CommitPairValues and BisectRuns, which are used to curate the information for Catapult Pinpoint. TODO(b/322203189) - This is a temporary solution for backwards compatibilty to the Catapult UI and should be removed when the catapult package is deprecated.

func BisectWorkflow 

func BisectWorkflow(ctx workflow.Context, p *workflows.BisectParams) (be *BisectExecution, wkErr error)

BisectWorkflow is a Workflow definition that takes a range of git hashes and finds the culprit.

type BisectRun 

type BisectRun struct {
	CommitRun
	ScheduledRuns []scheduledRun
}

BisectRun tracks current scheduled SingleCommitRun's and merges from other runs.

This is not thread-safe. Schedule and Update usually happens in an I/O nonblocking manner where they are invoked in the same thread vis select.

type BisectRunIndex 

type BisectRunIndex int

bisectRunTracker stores all the running bisect runs.

It keeps track of all the runs by indexes. The BisectRun will be updated from different future fulfillment. One can wait for a bisect run that's already triggered by a different bisection. This usually happens when the mid commit is computed and the result will be used for comparisions from both sides. This can also happen when one comparision requires more runs, and part of them is already triggered by another comparision.

type BuildActivity 

type BuildActivity struct{}

BuildActivity wraps Build Activities.

func (*BuildActivity) CleanupBuildActivity 

func (bca *BuildActivity) CleanupBuildActivity(ctx context.Context, buildID int64, status buildbucketpb.Status, project string) error

func (bca *BuildActivity) SearchOrBuildActivity(ctx context.Context, params workflows.BuildParams) (int64, error)

SearchOrBuildActivity searches for an existing build to reuse, or triggers a new one.

func (*BuildActivity) WaitBuildCompletionActivity 

func (bca *BuildActivity) WaitBuildCompletionActivity(ctx context.Context, buildID int64, project string) (buildbucketpb.Status, error)

WaitBuildCompletionActivity polls the build and waits until it is completed or errors.

type CollectAndUploadParams struct {
	// Project is the Google Cloud Project (ie/ chromeperf), used for creating the
	// fully qualified BQ table name.
	Project string
	// Dataset is the BQ Dataset. Format is {project}.{dataset}.
	// Used for creating the fully qualified BQ table name.

	// {project}.{dataset}.{tableName}. Used for creating the fully qualified BQ
	// table name.
	TableName string
	// Benchmark is the benchmark name, ie/ Speedometer3.
	Benchmark string
	// WorkflowID is the ID of the Temporal Workflow.

	Result           *compare.CompareResults
	OtherResult      *compare.CompareResults // record the other comparison

	CommitPairValues CommitPairValues
}

func CompareActivity 

func CompareActivity(ctx context.Context, allValues CommitPairValues, magnitude, errRate float64, direction compare.ImprovementDir) (*CombinedResults, error)

CompareActivity wraps compare.ComparePerformance and compare.CompareFunctional as activity

type CommitPairValues 

type CommitPairValues struct {
	Lower  CommitValues
	Higher CommitValues
}

func GetAllDataForCompareLocalActivity

TODO(sunxiaodi@): Change GetAllDataForCompareLocalActivity to a regular function

type CommitRangeTracker 

type CommitRangeTracker struct {
	Lower  BisectRunIndex
	Higher BisectRunIndex
}

It stores bisect run as indexes as it needs to be serialized. The indexes are stable within the workflow thru bisectRunTracker.

func (CommitRangeTracker) CloneWithHigher

	// SingleCommitRunnerParams includes a field for only one commit.
	LeftCommit, RightCommit *common.CombinedCommit

	// The random seed used to generate pairs.
	Seed int64
}

PairwiseCommitsRunnerParams defines the parameters for PairwiseCommitsRunner workflow.

type PairwiseRun 

type PairwiseRun struct {
	Left, Right CommitRun
	// Order represents the order of the runs between Left and Right.
	// 0 means Left went first and 1 means Right went first.
	// The order is needed to handle pair failures. If a pair fails,
	// another pair that went in the other order needs to be tossed
	// from the data analysis to ensure balancing.
	Order []workflows.PairwiseOrder
}

PairwiseRun is the output of the PairwiseCommitsRunnerWorkflow TODO(b/321306427): This struct assumes that the i-th Left and Right CommitRuns are part of the same pair. If this assumption breaks, consider refactoring this struct and the subsequent workflows to instead store a list of PairwiseTestRuns. Another potential reason for refactoring is if len(Order) != len(Left) or len(Right).

func PairwiseCommitsRunnerWorkflow 

func PairwiseCommitsRunnerWorkflow(ctx workflow.Context, pc PairwiseCommitsRunnerParams) (*PairwiseRun, error)

PairwiseCommitsRunnerWorkflow is a Workflow definition.
