bool AddFakeProvider (zx_koid_t pid, const std::string & name, FakeProvider ** out_provider)

The caller must run the loop to complete the registration.

If |*out_provider| is non-NULL, a borrowed copy of the pointer is

stored there, and is valid for the duration of the test.

void OnSessionStateChange ()

Called from within |TraceManager| on |TraceSession| state changes.

bool InitializeSession (fuchsia_tracing_controller::TraceConfig config)

Wrappers to simplify the standard operations.

These are only to be called at times when they're expected to succeed.

E.g., Don't call |TerminateSession()| if session is already terminated,

and so on. If you want to perform these operations outside of this

constraint, roll your own or use something else.

These assume the controller connection is already made.

The default session doesn't have a consumer.

bool TerminateSession ()

Defined at line 378 of file ../../src/performance/trace_manager/tests/trace_manager_test.cc

void BeginTerminateSession ()

Terminating a session involves two steps: Initiating the termination

and waiting for it to terminate. Call these when you want to access

intermediate state.

Defined at line 338 of file ../../src/performance/trace_manager/tests/trace_manager_test.cc

bool FinishTerminateSession ()

Returns true on success.

If |result| is non-NULL the result is stored there.

Defined at line 352 of file ../../src/performance/trace_manager/tests/trace_manager_test.cc

bool StartSession (fuchsia_tracing_controller::StartOptions options)

Wrappers to simplify |Start,Stop| operations.

These are only to be called at times when they're expected to succeed.

E.g., Don't call |StartSession*()| if session is already started,

and so on. If you want to perform these operations outside of this

constraint, roll your own or use something else.

These assume the needed interface is already connected.

These combine both the "begin" and "finish" operations.

Defined at line 251 of file ../../src/performance/trace_manager/tests/trace_manager_test.cc

bool StopSession (fuchsia_tracing_controller::StopOptions options)

Defined at line 333 of file ../../src/performance/trace_manager/tests/trace_manager_test.cc

void BeginStartSession (fuchsia_tracing_controller::StartOptions options)

Starting and stopping a session involves two steps: initiating the request

and waiting for it to complete. Call these when you want to access

intermediate state.

Defined at line 182 of file ../../src/performance/trace_manager/tests/trace_manager_test.cc

bool FinishStartSession ()

void MarkAllProvidersStarted ()

Helpers to advance provider state.

These can only be called when all providers are in the immediately

preceding state (e.g., kStarting->kStarted).

Defined at line 383 of file ../../src/performance/trace_manager/tests/trace_manager_test.cc

void MarkAllProvidersStopped ()

Defined at line 390 of file ../../src/performance/trace_manager/tests/trace_manager_test.cc

void MarkAllProvidersTerminated ()

Defined at line 397 of file ../../src/performance/trace_manager/tests/trace_manager_test.cc

void VerifyCounts (int expected_start_count, int expected_stop_count)

Helper to verify reception and processing of initialize, start, stop,

and terminate fidl requests.

This is not intended to be called before |Initialize*|.

Defined at line 404 of file ../../src/performance/trace_manager/tests/trace_manager_test.cc

Enumerations

enum SessionState
Name Value
kReady 0
kInitialized 1
kStarting 2
kStarted 3
kStopping 4
kStopped 5
kTerminating 6
kNonexistent 7

|TraceSession| intentionally doesn't have |kTerminated| as that is

represented by the session being non-existent. However, it's helpful in

tests to have a value to represent this state so we have our own copy of

|TraceSession::State|. It is not named |State| to help avoid confusion.
