Overview

Package monitor is a helper for keeping a local in memory representation of the key data from some of the robot services. It's purpose is to provice the main data source for packages like the web server and the scheduler. Most of the types are opaque about their contents to allow for lazy aquisition construction or lookup of their members. For instance, id's are normally resolved to objects for you, but that resolve may not happen until the member is asked for.

Functions

func Run 

func Run(ctx context.Context, managers Managers, owner DataOwner, update func(ctx context.Context, managers *Managers, data *Data) []error) error

Run is used to run a new monitor. It will monitor the data from all the managers that are in the supplied managers, filling in the data structure with all the results it receives. Each time it receives a batch of updates it will invoke the update function passing in the manager set being monitored and the updated set of data.

Types

type Data 

type Data struct {
	Gen *Generation

	Devices  Devices
	Workers  Workers
	Subjects Subjects
	Tracks   Tracks
	Packages Packages
	Traces   Traces
	Reports  Reports
	Replays  Replays
	// contains filtered or unexported fields
}

Data is the live store of data from the monitored servers. Entries with no live manager will not be updated.

func (*Data) FindDevice 

func (data *Data) FindDevice(id string) *Device

FindDevice searches the device list for one that matches the supplied id.

func (*Data) Wait 

func (data *Data) Wait()

type DataOwner 

type DataOwner struct {
	// contains filtered or unexported fields
}

func NewDataOwner 

func NewDataOwner() DataOwner

func (DataOwner) Read 

func (o DataOwner) Read(rf func(d *Data))

func (DataOwner) Write 

func (o DataOwner) Write(wf func(d *Data))

type Device 

type Device struct {
	job.Device
}

Device is the in memory representation/wrapper for a job.Device

type Devices 

type Devices struct {
	// contains filtered or unexported fields
}

Devices is the type that manages a set of Device objects.

func (*Devices) All 

func (d *Devices) All() []*Device

All returns the complete set of Device objects we have seen so far.

type Generation 

type Generation struct {
	// contains filtered or unexported fields
}

Generation is a way to handle sequences of 'updates' or 'generations', find out how many have happened, as well as blocking until the next one happens. This does not assume an 'update' to mean anything specific.

func NewGeneration 

func NewGeneration() *Generation

NewGeneration returns a new Generation starting with an id of 0.

func (*Generation) After 

func (g *Generation) After(id uint64) <-chan struct{}

After returns a channel that will be closed as soon as the generation exceeds ID. This is intended for use in select calls, if you just want to wait, WaitForUpdate is more efficient.

func (*Generation) Get 

func (g *Generation) Get() (uint64, chan struct{})

Get returns the generation identifier and blocking channel under the lock

func (*Generation) ID 

func (g *Generation) ID() uint64

ID returns the current generation identifier under the lock

func (*Generation) Update 

func (g *Generation) Update() uint64

Update increments the generation and notifies all blocked goroutines

func (*Generation) WaitForUpdate 

func (g *Generation) WaitForUpdate(previous uint64) uint64

WaitForUpdate blocks until the generation is past previous, and returns the current generation.

type Managers 

type Managers struct {
	Master  master.Master
	Stash   *stash.Client
	Job     job.Manager
	Build   build.Store
	Subject subject.Subjects
	Trace   trace.Manager
	Report  report.Manager
	Replay  replay.Manager
}

Managers describes the set of managers to monitor for data changes.

type Package 

type Package struct {
	build.Package
	// contains filtered or unexported fields
}

Package is the in memory representation/wrapper for a build.Package

func (*Package) FindTools 

func (p *Package) FindTools(ctx context.Context, d *Device) *build.ToolSet

FindTools returns the tool set that matches the supplied device, if the package has one.

func (*Package) FindToolsForAPK 

func (p *Package) FindToolsForAPK(ctx context.Context, host *Device, target *Device, apkInfo *apk.Information) *build.AndroidToolSet

FindToolsForAPK returns the best matching tool set for a certain apk on a device, if present in the package.

func (*Package) FindToolsForDevice added in v1.1.0 

func (p *Package) FindToolsForDevice(ctx context.Context, host *Device, target *Device) *build.AndroidToolSet

FindToolsForDevice returns the best matching tool set for a certain device.
