Class Controller2Client (1.3.2)

The Controller service provides the API for orchestrating a collection of debugger agents to perform debugging tasks. These agents are each attached to a process of an application which may include one or more replicas.

The debugger agents register with the Controller to identify the application being debugged, the Debuggee. All agents that register with the same data, represent the same Debuggee, and are assigned the same debuggee_id.

The debugger agents call the Controller to retrieve the list of active Breakpoints. Agents with the same debuggee_id get the same breakpoints list. An agent that can fulfill the breakpoint request updates the Controller with the breakpoint result. The controller selects the first result received and discards the rest of the results. Agents that poll again for active breakpoints will no longer have the completed breakpoint in the list and should remove that breakpoint from their attached process.

The Controller service does not provide a way to retrieve the results of a completed breakpoint. This functionality is available using the Debugger service.

Returns the transport used by the client instance.

Instantiates the controller2 client.

Releases underlying transport's resources.

Returns a fully-qualified billing_account string.

Returns a fully-qualified folder string.

Returns a fully-qualified location string.

Returns a fully-qualified organization string.

Returns a fully-qualified project string.

Creates an instance of this client using the provided credentials file.

Creates an instance of this client using the provided credentials info.

Creates an instance of this client using the provided credentials file.

Return the API endpoint and client cert source for mutual TLS.

The client cert source is determined in the following order: (1) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is not "true", the client cert source is None. (2) if client_options.client_cert_source is provided, use the provided one; if the default client cert source exists, use the default one; otherwise the client cert source is None.

The API endpoint is determined in the following order: (1) if client_options.api_endpoint if provided, use the provided one. (2) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "always", use the default mTLS endpoint; if the environment variabel is "never", use the default API endpoint; otherwise if client cert source exists, use the default mTLS endpoint, otherwise use the default API endpoint.

Returns the list of all active breakpoints for the debuggee.

The breakpoint specification (location, condition, and expressions fields) is semantically immutable, although the field values may change. For example, an agent may update the location line number to reflect the actual line where the breakpoint was set, but this doesn't change the breakpoint semantics.

This means that an agent does not need to check if a breakpoint has changed when it encounters the same breakpoint on a successive call. Moreover, an agent should remember the breakpoints that are completed until the controller removes them from the active list to avoid setting those breakpoints again.

def sample_list_active_breakpoints():
    # Create a client
    client = debugger_v2.Controller2Client()

    # Initialize request argument(s)
    request = debugger_v2.ListActiveBreakpointsRequest(
        debuggee_id="debuggee_id_value",
    )

    # Make the request
    response = client.list_active_breakpoints(request=request)

    # Handle the response
    print(response)

Parse a billing_account path into its component segments.

Parse a folder path into its component segments.

Parse a location path into its component segments.

Parse a organization path into its component segments.

Parse a project path into its component segments.

Registers the debuggee with the controller service.

All agents attached to the same application must call this method with exactly the same request content to get back the same stable debuggee_id. Agents should call this method again whenever google.rpc.Code.NOT_FOUND is returned from any controller method.

This protocol allows the controller service to disable debuggees, recover from data loss, or change the debuggee_id format. Agents must handle debuggee_id value changing upon re-registration.

def sample_register_debuggee():
    # Create a client
    client = debugger_v2.Controller2Client()

    # Initialize request argument(s)
    request = debugger_v2.RegisterDebuggeeRequest(
    )

    # Make the request
    response = client.register_debuggee(request=request)

    # Handle the response
    print(response)

Updates the breakpoint state or mutable fields. The entire Breakpoint message must be sent back to the controller service.

Updates to active breakpoint fields are only allowed if the new value does not change the breakpoint specification. Updates to the location, condition and expressions fields should not alter the breakpoint semantics. These may only make changes such as canonicalizing a value or snapping the location to the correct line of code.

from google.cloud import debugger_v2

def sample_update_active_breakpoint():
    # Create a client
    client = debugger_v2.Controller2Client()

    # Initialize request argument(s)
    request = debugger_v2.UpdateActiveBreakpointRequest(
        debuggee_id="debuggee_id_value",
    )

    # Make the request
    response = client.update_active_breakpoint(request=request)

    # Handle the response
    print(response)
