Expand description

Provides the process Handles and VMOs used to share code coverage to the fuzzing engine.

This protocol is implemented by test_manager’s fuzz_coverage component. The fuzzing engine acts as a client, although it does not connect directly. Instead the fuzz_test_runner makes the connection and passes it off to fuzzing engine on process start. It allows the engine to retrieve the coverage-related Handles published by instrumented target processes.

The channel is closed on FIDL error. Clients should exit and not attempt to reconnect.

Variants§

§

SetOptions

Fields

§options: Options

Sets the options to be returned by fuchsia.fuzzer.CoverageDataCollector/Initialize.

§

WatchCoverageData

Provides coverage data collected from multiple processes.

Returns a vector of CoverageData structs containing the information provided by clients of fuchsia.fuzzer.CoverageDataCollector. This method uses the “hanging get” pattern: The initial call will immediately return whatever data is available, up to MAX_COVERAGE_DATA. If no fuzzed components have been started yet, this be an empty vector. If there are more than MAX_COVERAGE_DATA elements available, the remainder are retained for subsequent calls. If there is no more data available, subsequent calls will block until new coverage data is available.

The channel is closed on FIDL error. Clients should exit and not attempt to reconnect.
