Types

type Experiment 

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

Experiment is an experiment instance.

func NewExperiment 

func NewExperiment(sess *Session, measurer model.ExperimentMeasurer) *Experiment

NewExperiment creates a new experiment given a measurer. The preferred way to create an experiment is the ExperimentBuilder. Though this function allows the programmer to create a custom, external experiment.

func (*Experiment) GetSummaryKeys 

func (e *Experiment) GetSummaryKeys(m *model.Measurement) (interface{}, error)

GetSummaryKeys returns a data structure containing a summary of the test keys for probe-cli.

func (*Experiment) KibiBytesReceived 

func (e *Experiment) KibiBytesReceived() float64

KibiBytesReceived accounts for the KibiBytes received by the HTTP clients managed by this session so far, including experiments.

func (*Experiment) KibiBytesSent 

func (e *Experiment) KibiBytesSent() float64

KibiBytesSent is like KibiBytesReceived but for the bytes sent.

func (*Experiment) Measure deprecated 

func (e *Experiment) Measure(input string) (*model.Measurement, error)

Measure performs a measurement with input. We assume that you have configured the available test helpers, either manually or by calling the session's MaybeLookupBackends() method.

Return value: strictly either a non-nil measurement and a nil error or a nil measurement and a non-nil error.

CAVEAT: while this API is perfectly fine for experiments that return a single measurement, it will only return the first measurement when used with an asynchronous experiment. We plan on eventually migrating all experiments to run in asynchronous fashion.

Deprecated: use MeasureWithContext instead, please.

func (*Experiment) MeasureAsync added in v3.14.0 

func (e *Experiment) MeasureAsync(
	ctx context.Context, input string) (<-chan *model.Measurement, error)

MeasureAsync runs an async measurement. This operation could post one or more measurements onto the returned channel. We'll close the channel when we've emitted all the measurements.

Arguments:

- ctx is the context for deadline/cancellation/timeout;

- input is the input (typically a URL but it could also be just an endpoint or an empty string for input-less experiments such as, e.g., ndt7 and dash).

Return value:

- on success, channel where to post measurements (the channel will be closed when done) and nil error;

- on failure, nil channel and non-nil error.

func (*Experiment) MeasureWithContext 

func (e *Experiment) MeasureWithContext(
	ctx context.Context, input string,
) (measurement *model.Measurement, err error)

MeasureWithContext is like Measure but with context.

Return value: strictly either a non-nil measurement and a nil error or a nil measurement and a non-nil error.

CAVEAT: while this API is perfectly fine for experiments that return a single measurement, it will only return the first measurement when used with an asynchronous experiment. We plan on eventually migrating all experiments to run in asynchronous fashion.

func (*Experiment) Name 

func (e *Experiment) Name() string

Name returns the experiment name.

func (*Experiment) OpenReport 

func (e *Experiment) OpenReport() (err error)

func (*Experiment) OpenReportContext 

func (e *Experiment) OpenReportContext(ctx context.Context) error

OpenReportContext will open a report using the given context to possibly limit the lifetime of this operation.

func (*ExperimentBuilder) SetOptionGuessType 

func (b *ExperimentBuilder) SetOptionGuessType(key, value string) error

SetOptionGuessType sets an option whose type depends on the option value. If the value is `"true"` or `"false"` we assume the option is boolean. If the value is numeric, then we set an integer option. Otherwise we set a string option.

type InputLoader 

type InputLoader struct {
	// CheckInConfig contains options for the CheckIn API. If

	// there are fields inside it that are not set, then we
	// will set them to a default value.
	CheckInConfig *model.CheckInConfig

	// ExperimentName is the name of the experiment. This field
	// is only used together with the InputOrStaticDefault policy.
	ExperimentName string

	// InputPolicy specifies the input policy for the
	// current experiment. We will not load any input if
	// the policy says we should not. You MUST fill in
	// this field.
	InputPolicy InputPolicy

	// Logger is the optional logger that the InputLoader
	// should be using. If not set, we will use the default
	// logger of github.com/apex/log.

	// MUST fill in this field.
	Session InputLoaderSession

	// StaticInputs contains optional input to be added
	// to the resulting input list if possible.
	StaticInputs []string

	// SourceFiles contains optional files to read input
	// from. Each file should contain a single input string
	// per line. We will fail if any file is unreadable
	// as well as if any file is empty.
	SourceFiles []string
}

InputLoader loads input according to the specified policy either from command line and input files or from OONI services. The behaviour depends on the input policy as described below.

You MUST NOT change any public field of this structure when in use, because that MAY lead to data races.

InputNone

We fail if there is any StaticInput or any SourceFiles. If there's no input, we return a single, empty entry that causes experiments that don't require input to run once.

InputOptional

We gather input from StaticInput and SourceFiles. If there is input, we return it. Otherwise we return a single, empty entry that causes experiments that don't require input to run once.

InputOrQueryBackend

We gather input from StaticInput and SourceFiles. If there is input, we return it. Otherwise, we use OONI's probe services to gather input using the best API for the task.

InputOrStaticDefault

We gather input from StaticInput and SourceFiles. If there is input, we return it. Otherwise, we return an internal static list of inputs to be used with this experiment.

InputStrictlyRequired

We gather input from StaticInput and SourceFiles. If there is input, we return it. Otherwise, we return an error.

func (*InputLoader) Load 

func (il *InputLoader) Load(ctx context.Context) ([]model.URLInfo, error)

Load attempts to load input using the specified input loader. We will return a list of URLs because this is the only input we support.

type InputLoaderLogger added in v3.9.2 

type InputLoaderLogger interface {
	// Warnf formats and emits a warning message.
	Warnf(format string, v ...interface{})
}

InputLoaderLogger is the logger according to an InputLoader.

type InputLoaderSession 

type InputLoaderSession interface {
	CheckIn(ctx context.Context,
		config *model.CheckInConfig) (*model.CheckInInfo, error)
}

InputLoaderSession is the session according to an InputLoader. We introduce this abstraction because it helps us with testing.

type InputPolicy 

type InputPolicy string

InputPolicy describes the experiment policy with respect to input. That is whether it requires input, optionally accepts input, does not want input.

type InputProcessor 

type InputProcessor struct {
	// Annotations contains the measurement annotations
	Annotations map[string]string

	// Experiment is the code that will run the experiment.
	Experiment InputProcessorExperimentWrapper

	// Inputs is the list of inputs to measure.
	Inputs []model.URLInfo

	// MaxRuntime is the optional maximum runtime
	// when looping over a list of inputs (e.g. when
	// running Web Connectivity). Zero means that
	// there will be no MaxRuntime limit.
	MaxRuntime time.Duration

	// Options contains command line options for this experiment.
	Options []string

	// Saver is the code that will save measurement results
	// on persistent storage (e.g. the file system).
	Saver InputProcessorSaverWrapper

	// Submitter is the code that will submit measurements
	// to the OONI collector.
	Submitter InputProcessorSubmitterWrapper
}

InputProcessor processes inputs. We perform a Measurement for each input using the given Experiment.

func (*InputProcessor) Run 

func (ip *InputProcessor) Run(ctx context.Context) error

Run processes all the input subject to the duration of the context. The code will perform measurements using the given experiment; submit measurements using the given submitter; save measurements using the given saver.

Annotations and Options will be saved in the measurement.

The default behaviour of this code is that an error while measuring, while submitting, or while saving a measurement is always causing us to break out of the loop. The user though is free to choose different policies by configuring the Experiment, Submitter, and Saver fields properly.

type InputProcessorExperiment 

type InputProcessorExperiment interface {
	MeasureAsync(
		ctx context.Context, input string) (<-chan *model.Measurement, error)
}

InputProcessorExperiment is the Experiment according to InputProcessor.

	Get(key string) (value []byte, err error)
	Set(key string, value []byte) (err error)
}

KVStore is a simple, atomic key-value store. The user of probe-engine should supply an implementation of this interface, which will be used by probe-engine to store specific data.

type OptionInfo 

type OptionInfo struct {
	Doc  string
	Type string
}

OptionInfo contains info about an option

type Saver

type Session 

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

Session is a measurement session. It contains shared information required to run a measurement session, and it controls the lifecycle of such resources. It is not possible to reuse a Session. You MUST NOT attempt to use a Session again after Session.Close.

func NewSession 

func NewSession(ctx context.Context, config SessionConfig) (*Session, error)

NewSession creates a new session. This factory function will execute the following steps:

1. Make sure the config is sane, apply reasonable defaults where possible, otherwise return an error.

2. Create a temporary directory.

3. Create an instance of the session.

4. If the user requested for a proxy that entails a tunnel (at the moment of writing this note, either psiphon or tor), then start the requested tunnel and configure it as our proxy.

5. Create a compound resolver for the session that will attempt to use a bunch of DoT/DoH servers before falling back to the system resolver if nothing else works (see the sessionresolver pkg). This sessionresolver will be using the configured proxy, if any.

6. Create the default HTTP transport that we should be using when we communicate with the OONI backends. This transport will be using the configured proxy, if any.

If any of these steps fails, then we cannot create a measurement session and we return an error.

func (*Session) CheckIn added in v3.9.0 

func (s *Session) CheckIn(
	ctx context.Context, config *model.CheckInConfig) (*model.CheckInInfo, error)

CheckIn calls the check-in API. The input arguments MUST NOT be nil. Before querying the API, this function will ensure that the config structure does not contain any field that SHOULD be initialized and is not initialized. Whenever there is a field that is not initialized, we will attempt to set a reasonable default value for such a field. This list describes the current defaults we'll choose:

- Platform: if empty, set to Session.Platform();

- ProbeASN: if empty, set to Session.ProbeASNString();

- ProbeCC: if empty, set to Session.ProbeCC();

- RunType: if empty, set to "timed";

- SoftwareName: if empty, set to Session.SoftwareName();

- SoftwareVersion: if empty, set to Session.SoftwareVersion();

- WebConnectivity.CategoryCodes: if nil, we will allocate an empty array (the API does not like nil).

Because we MAY need to know the current ASN and CC, this function MAY call MaybeLookupLocationContext.

The return value is either the check-in response or an error.

func (*Session) Close 

func (s *Session) Close() error

Close ensures that we close all the idle connections that the HTTP clients we are currently using may have created. It will also remove the temp dir that contains data from this session. Not calling this function may likely cause memory leaks in your application because of open idle connections, as well as excessive usage of disk space.

func (*Session) NewProbeServicesClient 

func (s *Session) NewProbeServicesClient(ctx context.Context) (*probeservices.Client, error)

NewProbeServicesClient creates a new client for talking with the OONI probe services. This function will benchmark the available probe services, and select the fastest.
