Constants

View Source 
const LEDBuilderIsBootstrappedProperty = "led_builder_is_bootstrapped"

LEDBuilderIsBootstrappedProperty should be set to a boolean value. If true, edit-recipe-bundle will set the "led_cas_recipe_bundle" property instead of overwriting the build's payload.

View Source 
const RecipeDirectory = "kitchen-checkout"

RecipeDirectory is a very unfortunate constant which is here for a combination of reasons:

  1. swarming doesn't allow you to 'checkout' an isolate relative to any path in the task (other than the task root). This means that whatever value we pick for EditRecipeBundle must be used EVERYWHERE the isolated hash is used.
  2. Currently the 'recipe_engine/led' module will blindly take the isolated input and 'inject' it into further uses of led. This module currently doesn't specify the checkout dir, relying on kitchen's default value of (you guessed it) "kitchen-checkout".

In order to fix this (and it will need to be fixed for bbagent support):

  • The 'recipe_engine/led' module needs to accept 'checkout-dir' as a parameter in its input properties.
  • led needs to start passing the checkout dir to the led module's input properties.
  • `led edit` needs a way to manipulate the checkout directory in a job
  • The 'recipe_engine/led' module needs to set this in the job alongside the isolate hash when it's doing the injection.

For now, we just hard-code it.

TODO(crbug.com/1072117): Fix this, it's weird.

	LegacyKitchen bool `protobuf:"varint,9,opt,name=legacy_kitchen,json=legacyKitchen,proto3" json:"legacy_kitchen,omitempty"`
	// Eventually becomes the name of the launched swarming task.
	Name string `protobuf:"bytes,10,opt,name=name,proto3" json:"name,omitempty"`
	// This field contains the path relative to ${ISOLATED_OUTDIR} for the final

	//
	// For bbagent-based jobs this must have the file extension ".pb", ".textpb"
	// or ".json", to get the respective encoding.
	//
	// For legacy kitchen jobs this must have the file extension ".json".
	//
	// By default, led will populate this with "build.proto.json".
	FinalBuildProtoPath string `protobuf:"bytes,11,opt,name=final_build_proto_path,json=finalBuildProtoPath,proto3" json:"final_build_proto_path,omitempty"`

	RealBuild bool `protobuf:"varint,12,opt,name=real_build,json=realBuild,proto3" json:"real_build,omitempty"`
	// contains filtered or unexported fields
}

Buildbucket is, ideally, just a BBAgentArgs, but there are bits of data that led needs to track which aren't currently contained in BBAgentArgs.

Where it makes sense, this additional data should be moved from this Buildbucket message into BBAgentArgs, but for now we store it separately to get led v2 up and running.

type Definition_Buildbucket 

type Definition_Buildbucket struct {
	// Represents a buildbucket-native task; May be recovered from a swarming
	// task, or provided directly via buildbucket.
	Buildbucket *Buildbucket `protobuf:"bytes,1,opt,name=buildbucket,proto3,oneof"`
}

type Definition_Swarming 

type Definition_Swarming struct {
	// Represents a swarming task. This will be filled for jobs sourced directly
	// from swarming which weren't recognized as a buildbucket task.
	//
	// A limited subset of the edit and info functionality is available for
	// raw swarming jobs.
	Swarming *Swarming `protobuf:"bytes,2,opt,name=swarming,proto3,oneof"`
}

type DimensionEditCommand 

type DimensionEditCommand struct {
	SetValues    []ExpiringValue
	RemoveValues []string
	AddValues    []ExpiringValue
}

DimensionEditCommand is instruction on how to process the values in the task associated with a swarming dimension.

The fields are processed in order:

  • if SetValues is non-nil, the dimension values are set to this set (including empty).
  • if RemoveValues is non-empty, these values will be removed from the dimension values.
  • if AddValues is non-empty, these values will ber added to the dimension values.

If the set of values at the end of this process is empty, the dimension will be removed from the task. Otherwise the dimension will be set to the sorted remaining values.

type DimensionEditCommands 

type DimensionEditCommands map[string]*DimensionEditCommand

DimensionEditCommands is a mapping of dimension name to a set of commands to apply to the values of that dimension.

func MakeDimensionEditCommands 

func MakeDimensionEditCommands(commands []string) (DimensionEditCommands, error)

MakeDimensionEditCommands takes a slice of commands in the form of: 

dimension=
dimension=value
dimension=value@1234

dimension-=value

dimension+=value
dimension+=value@1234

Logically:

  • dimension_name - The name of the dimension to modify
  • operator
  • "=" - Add value to SetValues. If empty, ensures that SetValues is non-nil (i.e. clear all values for this dimension).
  • "-=" - Add value to RemoveValues.
  • "+=" - Add value to AddValues.
  • value - The dimension value for the operand
  • expiration seconds - The time at which this value should expire.

All equivalent operations for the same dimension will be grouped into a single DimensionEditCommand in the order they appear in `commands`.

type Editor 

type Editor interface {
	// ClearCurrentIsolated removes all isolateds from this Definition.
	ClearCurrentIsolated()

	// ClearDimensions removes all dimensions.
	ClearDimensions()

	// SetDimensions sets the full set of dimensions.
	SetDimensions(dims ExpiringDimensions)

	// EditDimensions edits the swarming dimensions.
	EditDimensions(dimEdits DimensionEditCommands)

	// CIPDPkgs allows you to edit the cipd packages. The mapping is in the form
	// of:
	//
	//    "subdir:name/of/package" -> "version"
	//
	// If version is empty, this package will be removed (if it's present).
	CIPDPkgs(cipdPkgs CIPDPkgs)

	// Env edits the swarming environment variables (i.e. those set before the
	// user payload runs).
	//
	// The map given is a map of environment variable to its value; If the value
	// is "", then the environment variable is removed.
	Env(env map[string]string)

	// PrefixPathEnv controls swarming's env_prefix mapping for $PATH.
	//
	// Values prepended with '!' will remove them from the existing list of values
	// (if present). Otherwise these values will be appended to the current list
	// of PATH-prefix-envs.
	PrefixPathEnv(values []string)

	// Priority edits the swarming task priority.
	Priority(priority int32)

	// SwarmingHostname allows you to modify the current SwarmingHostname used by
	// this led pipeline.
	SwarmingHostname(host string)

	// TaskName allows you to set the swarming task name of the job.
	TaskName(name string)

	// Tags appends the given values to the task's tags.
	Tags(values []string)
}

Editor represents low-level mutations you can make on a job.Definition.

You may edit a job.Definition by calling its Edit method.

type ExpiringDimensions 

type ExpiringDimensions map[string][]ExpiringValue

ExpiringDimensions is a map from dimension name to a list of values corresponding to that dimension.

When retrieved from a led library, the values will be sorted by expiration time, followed by value. Expirations of 0 (i.e. "infinite") are sorted last.

func (ExpiringDimensions) String 

func (e ExpiringDimensions) String() string

type ExpiringValue 

type ExpiringValue struct {
	Value      string
	Expiration time.Duration
}

ExpiringValue represents a tuple of dimension value, plus an expiration time.

If Expiration is zero, it counts as "no expiration".

type HighLevelEditor 

type HighLevelEditor interface {
	Editor

	// Experimental sets the task to either be marked 'experimental' or not.
	Experimental(isExperimental bool)

	// Experiments enables or disables experiments.
	//
	// If `exps[<name>]` is true, the corresponding experiment will be enabled.
	// If it is false, the experiment will be disabled (if it was enabled).
	//
	// Experiments enabled in the build, but not mentioned in `exps` map are left
	// enabled.
	Experiments(exps map[string]bool)

	// Properties edits the recipe properties.
	//
	// `props` should be a mapping of the top-level property to JSON-encoded data
	// for the value of this property. If the value is "", then the top-level
	// property will be deleted.
	//
	// If `auto` is true, then values which do not decode as JSON will be treated
	// as literal strings. For example, given a value `literal string` with
	// auto=true, this would be equivalent to passing the value `"literal string"`
	// with auto=false.
	Properties(props map[string]string, auto bool)

	// TaskPayloadSource sets the task payload to either use the provided CIPD
	// package and version, or the UserPayload if they are empty.
	//
	// If cipdPkg is specified without cipdVers, cipdVers will be set to "latest".
	TaskPayloadSource(cipdPkg, cipdVers string)

	// TaskPayloadPath sets the location of where bbagent should locate the task
	// payload data within the task.
	TaskPayloadPath(path string)

	// CASTaskPayload sets the cas reference as the build's user payload.
	CASTaskPayload(path string, casRef *swarmingpb.CASReference)

	// TaskPayloadCmd sets the arguments used to run the task payload.
	//
	// args[0] is the path, relative to the payload path, of the executable to
	// run.
	//
	// NOTE: Kitchen tasks ignore this value.
	TaskPayloadCmd(args []string)

	// ClearGerritChanges removes all GerritChanges from the job.
	ClearGerritChanges()

	// AddGerritChange ensures the GerritChange is in the set of input CLs.
	AddGerritChange(cl *bbpb.GerritChange)

	// RemoveGerritChange ensures the GerritChange is not in the set of input CLs.
	RemoveGerritChange(cl *bbpb.GerritChange)

	// GitilesCommit sets the GitilesCommit.
	//
	// If `commit` is nil, removes the commit.
	GitilesCommit(commit *bbpb.GitilesCommit)
}

HighLevelEditor represents high-level mutations you can make on a job.Definition.

Currently only Buildbucket job.Definitions support high level edits.

You may edit a job.Definition by calling its HighLevelEdit method.

type HighLevelInfo interface {
	Info

	// Returns true iff the job is marked as 'experimental'.
	Experimental() bool

	// Returns a sorted list of enabled experiments.
	Experiments() []string

	// its JSON-encoded value.
	Properties() (map[string]string, error)

	// TaskPayloadSource returns the CIPD package and version of the user's task
	// payload. If they are empty, then it means the source of the user task
	// payload is within the UserPayload in the job.Definition.
	TaskPayloadSource() (cipdPkg, cipdVers string)

	// TaskPayloadPath returns the location of where bbagent/kitchen will locate
	// the task payload data within the task.
	TaskPayloadPath() (path string)

	// TaskPayloadCmd returns the arguments used to run the task payload.
	//

	TaskPayloadCmd() (args []string)

	// Returns the gerrit changes associated with this job.
	GerritChanges() []*bbpb.GerritChange

	// Returns the gitiles commit associated with this job.
	GitilesCommit() *bbpb.GitilesCommit
}

HighLevelInfo represents high-level information for Buildbucket job Definitions.

HighLevelInfo includes all capabilities of `Info` as well.

type Info 

type Info interface {
	// SwarmingHostname retrieves the Swarming hostname this Definition will use.
	SwarmingHostname() string

	// TaskName retrieves the human-readable Swarming task name from the
	// Definition.
	TaskName() string

	// CurrentIsolated returns the current isolated contents for the
	// Definition. If the CASReference has no hash value,
	// this returns an empty isolated obj.
	//
	// Returns error if this is a Swarming job where the slices have differing
	// isolateds.
	CurrentIsolated() (*swarmingpb.CASReference, error)

	// Dimensions returns a single map of all dimensions in the job Definition
	// and what their latest expiration is.
	//
	// For dimensions which "don't expire", they will report an expiration time of
	// the total task expiration.
	Dimensions() (ExpiringDimensions, error)

	// CIPDPkgs returns the mapping of all CIPD packages in the task, in the
	// same format that Editor.CIPDPkgs takes.

	// Priority returns the job's current swarming priority value.
	Priority() int32

	// Tags returns the job's current swarming tags.
	Tags() []string
}

Info represents the common low-level information for all job Definitions.

Swarming and Buildbucket implement this interface.

type KitchenSupport 

type KitchenSupport interface {
	FromSwarmingV2(ctx context.Context, in *swarmingpb.NewTaskRequest, out *Buildbucket) error
	GenerateCommand(ctx context.Context, bb *Buildbucket) ([]string, error)
}

KitchenSupport is the object for an interface to support 'LegacyKitchen' job definitions.

See 'infra/tools/led2' for the only real implementation of this.

This is abstracted out because 'kitchen' and its libraries live in infra, not in luci-go. Once kitchen is deleted, this will go away as well.

func NoKitchenSupport 

func NoKitchenSupport() KitchenSupport

NoKitchenSupport returns a null implementation of KitchenSupport which always returns errors if it ends up processing a kitchen job.

type RDBEnablement 

type RDBEnablement string

For accepting the "-resultdb" flag of "led launch". 

const (
	// Swarming/ResultDB integration will be forcefully enabled.
	RDBOn RDBEnablement = "on"
	// Swarming/ResultDB integration will be forcefully disabled.
	RDBOff RDBEnablement = "off"
)

func (*RDBEnablement) Set 

func (r *RDBEnablement) Set(v string) error

func (*RDBEnablement) String 

func (r *RDBEnablement) String() string

type Swarming 

type Swarming struct {
	Task     *api_v2.NewTaskRequest `protobuf:"bytes,1,opt,name=task,proto3" json:"task,omitempty"`
	Hostname string                 `protobuf:"bytes,2,opt,name=hostname,proto3" json:"hostname,omitempty"`
	// If set, this holds the CASReference to use with the job, when launched.
	//
	// At the time of launch, this will be merged with
	// swarming.task_slice[*].properties.cas_input_root, if any.
	CasUserPayload *api_v2.CASReference `protobuf:"bytes,3,opt,name=cas_user_payload,json=casUserPayload,proto3" json:"cas_user_payload,omitempty"`
	// contains filtered or unexported fields
}

Swarming is the raw TaskRequest. When a Definition is in this form, the user's ability to manipulate it via `led` subcommands is extremely limited.
