Google Cloud Debugger v2 API - Class Controller2ClientImpl (3.1.0)

public sealed class Controller2ClientImpl : Controller2Client

Reference documentation and code samples for the Google Cloud Debugger v2 API class Controller2ClientImpl.

Controller2 client wrapper implementation, for convenient use.

Inheritance

Object > Controller2Client > Controller2ClientImpl

Namespace

Google.Cloud.Debugger.V2

Assembly

Google.Cloud.Debugger.V2.dll

Remarks

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.

Constructors

Controller2ClientImpl(Controller2.Controller2Client, Controller2Settings, ILogger)

public Controller2ClientImpl(Controller2.Controller2Client grpcClient, Controller2Settings settings, ILogger logger)

Constructs a client wrapper for the Controller2 service, with the specified gRPC client and settings.

Parameters
NameDescription
grpcClientController2.Controller2Client

The underlying gRPC client.

settingsController2Settings

The base Controller2Settings used within this client.

loggerILogger

Optional ILogger to use within this client.

Properties

Methods

ListActiveBreakpoints(ListActiveBreakpointsRequest, CallSettings)

public override ListActiveBreakpointsResponse ListActiveBreakpoints(ListActiveBreakpointsRequest request, CallSettings callSettings = null)

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.

Parameters
NameDescription
requestListActiveBreakpointsRequest

The request object containing all of the parameters for the API call.

callSettingsCallSettings

If not null, applies overrides to this RPC call.

Returns
TypeDescription
ListActiveBreakpointsResponse

The RPC response.

Overrides

ListActiveBreakpointsAsync(ListActiveBreakpointsRequest, CallSettings)

public override Task<ListActiveBreakpointsResponse> ListActiveBreakpointsAsync(ListActiveBreakpointsRequest request, CallSettings callSettings = null)

Returns the list of all active breakpoints for the debuggee.

Parameters
NameDescription
requestListActiveBreakpointsRequest

The request object containing all of the parameters for the API call.

callSettingsCallSettings

If not null, applies overrides to this RPC call.

Returns
TypeDescription
Task<ListActiveBreakpointsResponse>

A Task containing the RPC response.

Overrides

RegisterDebuggee(RegisterDebuggeeRequest, CallSettings)

public override RegisterDebuggeeResponse RegisterDebuggee(RegisterDebuggeeRequest request, CallSettings callSettings = null)

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.

Parameters
NameDescription
requestRegisterDebuggeeRequest

The request object containing all of the parameters for the API call.

callSettingsCallSettings

If not null, applies overrides to this RPC call.

Returns
TypeDescription
RegisterDebuggeeResponse

The RPC response.

Overrides

RegisterDebuggeeAsync(RegisterDebuggeeRequest, CallSettings)

public override Task<RegisterDebuggeeResponse> RegisterDebuggeeAsync(RegisterDebuggeeRequest request, CallSettings callSettings = null)

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.

Parameters
NameDescription
requestRegisterDebuggeeRequest

The request object containing all of the parameters for the API call.

callSettingsCallSettings

If not null, applies overrides to this RPC call.

Returns
TypeDescription
Task<RegisterDebuggeeResponse>

A Task containing the RPC response.

Overrides

UpdateActiveBreakpoint(UpdateActiveBreakpointRequest, CallSettings)

public override UpdateActiveBreakpointResponse UpdateActiveBreakpoint(UpdateActiveBreakpointRequest request, CallSettings callSettings = null)

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.

Parameters
NameDescription
requestUpdateActiveBreakpointRequest

The request object containing all of the parameters for the API call.

callSettingsCallSettings

If not null, applies overrides to this RPC call.

Returns
TypeDescription
UpdateActiveBreakpointResponse

The RPC response.

Overrides

UpdateActiveBreakpointAsync(UpdateActiveBreakpointRequest, CallSettings)

public override Task<UpdateActiveBreakpointResponse> UpdateActiveBreakpointAsync(UpdateActiveBreakpointRequest request, CallSettings callSettings = null)

Parameters
NameDescription
