Functions

func NewExperimentMeasurer

func NewExperimentMeasurer(config Config) model.ExperimentMeasurer

NewExperimentMeasurer creates a new ExperimentMeasurer.

Types

type Config

type Config struct {
	// DisablePersistentDatadir disables using a persistent datadir.
	DisablePersistentDatadir bool `ooni:"Disable using a persistent tor datadir"`

	// DisableProgress disables printing progress messages.
	DisableProgress bool `ooni:"Disable printing progress messages"`

	// RendezvousMethod allows to choose the method with which to rendezvous.
	RendezvousMethod string `` /* 148-byte string literal not displayed */
}

Config contains the experiment config.

type Measurer

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

Measurer performs the measurement.

func (*Measurer) ExperimentName

func (m *Measurer) ExperimentName() string

ExperimentName implements model.ExperimentMeasurer.ExperimentName.

func (*Measurer) ExperimentVersion

func (m *Measurer) ExperimentVersion() string

ExperimentVersion implements model.ExperimentMeasurer.ExperimentVersion.

func (*Measurer) GetSummaryKeys

func (m *Measurer) GetSummaryKeys(measurement *model.Measurement) (interface{}, error)

GetSummaryKeys implements model.ExperimentMeasurer.GetSummaryKeys.

func (*Measurer) Run

func (m *Measurer) Run(
	ctx context.Context, sess model.ExperimentSession,
	measurement *model.Measurement, callbacks model.ExperimentCallbacks,
) error

Run runs the experiment with the specified context, session, measurement, and experiment calbacks. This method should only return an error in case the experiment could not run (e.g., a required input is missing). Otherwise, the code should just set the relevant OONI error inside of the measurement and return nil. This is important because the caller may not submit the measurement if this method returns an error.

type SummaryKeys

type SummaryKeys struct {
	IsAnomaly bool `json:"-"`
}

SummaryKeys contains summary keys for this experiment.

Note that this structure is part of the ABI contract with ooniprobe therefore we should be careful when changing it.

type TestKeys

type TestKeys struct {
	// BootstrapTime contains the bootstrap time on success.
	BootstrapTime float64 `json:"bootstrap_time"`

	// Error is one of `null`, `"timeout-reached"`, and `"unknown-error"` (this
	// field exists for backward compatibility with the previous
	// `vanilla_tor` implementation).
	Error *string `json:"error"`

	// Failure contains the failure string or nil.
	Failure *string `json:"failure"`

	// Success indicates whether we succeded (this field exists for
	// backward compatibility with the previous `vanilla_tor` implementation).
	Success bool `json:"success"`

	// PersistentDatadir indicates whether we're using a persistent tor datadir.
	PersistentDatadir bool `json:"persistent_datadir"`

	// RendezvousMethod contains the method used to perform the rendezvous.
	RendezvousMethod string `json:"rendezvous_method"`

	// Timeout contains the default timeout for this experiment
	Timeout float64 `json:"timeout"`

	// TorLogs contains the bootstrap logs.
	TorLogs []string `json:"tor_logs"`

	// TorProgress contains the percentage of the maximum progress reached.
	TorProgress int64 `json:"tor_progress"`

	// TorProgressTag contains the tag of the maximum progress reached.
	TorProgressTag string `json:"tor_progress_tag"`

	// TorProgressSummary contains the summary of the maximum progress reached.
	TorProgressSummary string `json:"tor_progress_summary"`

	// TorVersion contains the version of tor (if it's possible to obtain it).
	TorVersion string `json:"tor_version"`

	// TransportName is always set to "snowflake" for this experiment.
	TransportName string `json:"transport_name"`
}

TestKeys contains the experiment's result.
