Documentation

Overview

Package debugger is an auto-generated package for the Stackdriver Debugger API.

Examines the call stack and variables of a running application without stopping or slowing it down.

General documentation

For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go.

Example usage

To get started with this package, create a client. 

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := debugger.NewController2Client(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client. 

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := debugger.NewController2Client(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

req := &debuggerpb.RegisterDebuggeeRequest{
	// TODO: Fill request struct fields.
	// See https://pkg.go.dev/cloud.google.com/go/debugger/apiv2/debuggerpb#RegisterDebuggeeRequest.
}
resp, err := c.RegisterDebuggee(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewController2Client is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

Functions

func DefaultAuthScopes added in v0.8.0 

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

Types

type Controller2CallOptions 

type Controller2CallOptions struct {
	RegisterDebuggee       []gax.CallOption
	ListActiveBreakpoints  []gax.CallOption
	UpdateActiveBreakpoint []gax.CallOption
}

Controller2CallOptions contains the retry settings for each method of Controller2Client.

type Controller2Client 

type Controller2Client struct {

	// The call options for this service.
	CallOptions *Controller2CallOptions
	// contains filtered or unexported fields
}

Controller2Client is a client for interacting with Stackdriver Debugger API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

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.

func NewController2Client 

func NewController2Client(ctx context.Context, opts ...option.ClientOption) (*Controller2Client, error)

NewController2Client creates a new controller2 client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

func NewController2RESTClient added in v0.108.0 

func NewController2RESTClient(ctx context.Context, opts ...option.ClientOption) (*Controller2Client, error)

NewController2RESTClient creates a new controller2 rest client.

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.

Example 
package main

import (
	"context"

	debugger "cloud.google.com/go/debugger/apiv2"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := debugger.NewController2RESTClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

Output:

func (*Controller2Client) Close 

func (c *Controller2Client) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*Controller2Client) Connection deprecated 

func (c *Controller2Client) Connection() *grpc.ClientConn

Connection returns a connection to the API service.

Deprecated: Connections are now pooled so this method does not always return the same resource.

func (*Controller2Client) ListActiveBreakpoints 

func (c *Controller2Client) ListActiveBreakpoints(ctx context.Context, req *debuggerpb.ListActiveBreakpointsRequest, opts ...gax.CallOption) (*debuggerpb.ListActiveBreakpointsResponse, error)

ListActiveBreakpoints 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.

Example 
package main

import (
	"context"

	debugger "cloud.google.com/go/debugger/apiv2"
	debuggerpb "cloud.google.com/go/debugger/apiv2/debuggerpb"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := debugger.NewController2Client(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &debuggerpb.ListActiveBreakpointsRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/cloud.google.com/go/debugger/apiv2/debuggerpb#ListActiveBreakpointsRequest.
	}
	resp, err := c.ListActiveBreakpoints(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*Controller2Client) RegisterDebuggee 

func (c *Controller2Client) RegisterDebuggee(ctx context.Context, req *debuggerpb.RegisterDebuggeeRequest, opts ...gax.CallOption) (*debuggerpb.RegisterDebuggeeResponse, error)

RegisterDebuggee 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.

Example 
package main

import (
	"context"

	debugger "cloud.google.com/go/debugger/apiv2"
	debuggerpb "cloud.google.com/go/debugger/apiv2/debuggerpb"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := debugger.NewController2Client(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &debuggerpb.RegisterDebuggeeRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/cloud.google.com/go/debugger/apiv2/debuggerpb#RegisterDebuggeeRequest.
	}
	resp, err := c.RegisterDebuggee(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*Controller2Client) UpdateActiveBreakpoint 

func (c *Controller2Client) UpdateActiveBreakpoint(ctx context.Context, req *debuggerpb.UpdateActiveBreakpointRequest, opts ...gax.CallOption) (*debuggerpb.UpdateActiveBreakpointResponse, error)

UpdateActiveBreakpoint 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.

Example 
package main

import (
	"context"

	debugger "cloud.google.com/go/debugger/apiv2"
	debuggerpb "cloud.google.com/go/debugger/apiv2/debuggerpb"
)

Debugger2Client is a client for interacting with Stackdriver Debugger API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

The Debugger service provides the API that allows users to collect run-time information from a running application, without stopping or slowing it down and without modifying its state. An application may include one or more replicated processes performing the same work.

A debugged application is represented using the Debuggee concept. The Debugger service provides a way to query for available debuggees, but does not provide a way to create one. A debuggee is created using the Controller service, usually by running a debugger agent with the application.

The Debugger service enables the client to set one or more Breakpoints on a Debuggee and collect the results of the set Breakpoints.
