Cloud Debugger V2 API - Class Google::Cloud::Debugger::V2::Controller::Client (v0.4.0)

Reference documentation and code samples for the Cloud Debugger V2 API class Google::Cloud::Debugger::V2::Controller::Client.

Client for the Controller service.

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.

Methods

.configure

def self.configure() { |config| ... } -> Client::Configuration

Configure the Controller Client class.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns
Example 
# Modify the configuration for all Controller clients
::Google::Cloud::Debugger::V2::Controller::Client.configure do |config|
  config.timeout = 10.0
end

#configure

def configure() { |config| ... } -> Client::Configuration

Configure the Controller Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on Client.configure.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns

#initialize

def initialize() { |config| ... } -> Client

Create a new Controller client object.

Yields
  • (config) — Configure the Controller client.
Yield Parameter
Returns
  • (Client) — a new instance of Client
Example 
# Create a client using the default configuration
client = ::Google::Cloud::Debugger::V2::Controller::Client.new

# Create a client using a custom configuration
client = ::Google::Cloud::Debugger::V2::Controller::Client.new do |config|
  config.timeout = 10.0
end

#list_active_breakpoints

def list_active_breakpoints(request, options = nil) -> ::Google::Cloud::Debugger::V2::ListActiveBreakpointsResponse
def list_active_breakpoints(debuggee_id: nil, wait_token: nil, success_on_timeout: nil) -> ::Google::Cloud::Debugger::V2::ListActiveBreakpointsResponse

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.

Overloads 
def list_active_breakpoints(request, options = nil) -> ::Google::Cloud::Debugger::V2::ListActiveBreakpointsResponse
Pass arguments to list_active_breakpoints via a request object, either of type ListActiveBreakpointsRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Debugger::V2::ListActiveBreakpointsRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional. 
def list_active_breakpoints(debuggee_id: nil, wait_token: nil, success_on_timeout: nil) -> ::Google::Cloud::Debugger::V2::ListActiveBreakpointsResponse
Pass arguments to list_active_breakpoints via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • debuggee_id (::String) — Required. Identifies the debuggee.
  • wait_token (::String) — A token that, if specified, blocks the method call until the list of active breakpoints has changed, or a server-selected timeout has expired. The value should be set from the next_wait_token field in the last response. The initial value should be set to "init".
  • success_on_timeout (::Boolean) — If set to true (recommended), returns google.rpc.Code.OK status and sets the wait_expired response field to true when the server-selected timeout has expired.

    If set to false (deprecated), returns google.rpc.Code.ABORTED status when the server-selected timeout has expired.

Yields
  • (response, operation) — Access the result along with the RPC operation
Yield Parameters
Returns
Raises
  • (::Google::Cloud::Error) — if the RPC is aborted.
Example

Basic example

require "google/cloud/debugger/v2"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Debugger::V2::Controller::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Debugger::V2::ListActiveBreakpointsRequest.new

# Call the list_active_breakpoints method.
result = client.list_active_breakpoints request

# The returned object is of type Google::Cloud::Debugger::V2::ListActiveBreakpointsResponse.
p result

#register_debuggee

def register_debuggee(request, options = nil) -> ::Google::Cloud::Debugger::V2::RegisterDebuggeeResponse
def register_debuggee(debuggee: nil) -> ::Google::Cloud::Debugger::V2::RegisterDebuggeeResponse

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.

Overloads 
def register_debuggee(request, options = nil) -> ::Google::Cloud::Debugger::V2::RegisterDebuggeeResponse
Pass arguments to register_debuggee via a request object, either of type RegisterDebuggeeRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Debugger::V2::RegisterDebuggeeRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional. 
def register_debuggee(debuggee: nil) -> ::Google::Cloud::Debugger::V2::RegisterDebuggeeResponse
Pass arguments to register_debuggee via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameter
  • debuggee (::Google::Cloud::Debugger::V2::Debuggee, ::Hash) — Required. Debuggee information to register. The fields project, uniquifier, description and agent_version of the debuggee must be set.
Yields
  • (response, operation) — Access the result along with the RPC operation
Yield Parameters
Returns
Raises
  • (::Google::Cloud::Error) — if the RPC is aborted.

#update_active_breakpoint

def update_active_breakpoint(request, options = nil) -> ::Google::Cloud::Debugger::V2::UpdateActiveBreakpointResponse
def update_active_breakpoint(debuggee_id: nil, breakpoint: nil) -> ::Google::Cloud::Debugger::V2::UpdateActiveBreakpointResponse

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.
