ComputeTCPBlocking will return a copy of the input TCPConnect structure where we set the Blocking value depending on the control results.

Connects performs 0..N connects (either using TCP or TLS) to check whether the resolved endpoints are reachable.

Control performs the control request and returns the response.

DetermineBlocking returns the value of Summary.Blocking according to the expectations of OONI data consumers (nil|false|string).

DNSAnalysis compares the measurement and the control DNS results.

DNSLookup performs the DNS lookup part of Web Connectivity.

HTTPAnalysis performs follow-up analysis on the webconnectivity measurement by comparing the measurement test keys and the control.

HTTPBodyLengthChecks returns whether the measured body is reasonably long as much as the control body as well as the proportion between the two bodies.

HTTPGet performs the HTTP/HTTPS part of Web Connectivity.

HTTPGetMakeDNSCache constructs the DNSCache option for HTTPGet by combining domain and addresses into a single string.

HTTPHeadersMatch returns whether uncommon headers match between control and measurement, or nil if check is not applicable.

HTTPStatusCodeMatch returns whether the status code of the measurement matches the status code of the control, or nil if such comparison is actually not applicable.

HTTPTitleMatch returns whether the measurement and the control titles reasonably match, or nil if not applicable.

NewEndpointPort creates an EndpointPort from the given URL.

NewEndpoints creates a list of TCP/TLS endpoints to test from the target URL and the list of resolved IP addresses.

NewExperimentMeasurer creates a new ExperimentMeasurer.

Summarize computes the summary from the TestKeys.
