Structure of this Library

The API is structured into the following primary items:

  • Hub
    • a central object to maintain state and allow accessing all Activities
    • creates Method Builders which in turn allow access to individual Call Builders
  • Resources
    • primary types that you can apply Activities to
    • a collection of properties and Parts
    • Parts
      • a collection of properties
      • never directly used in Activities
  • Activities
    • operations to apply to Resources

All structures are marked with applicable traits to further categorize them and ease browsing.

Generally speaking, you can invoke Activities like this:

let r = hub.resource().activity(...).doit()

Or specifically ...

let r = hub.debugger().debuggees_breakpoints_set(...).doit()

The resource() and activity(...) calls create builders. The second one dealing with Activities supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be specified right away (i.e. (...)), whereas all optional ones can be build up as desired. The doit() method performs the actual communication with the server and returns the respective result.

Usage

Setting up your Project

To use this library, you would put the following lines into your Cargo.toml file:

[dependencies]
google-clouddebugger2 = "*"

A complete example

extern crate hyper;
extern crate yup_oauth2 as oauth2;
extern crate google_clouddebugger2 as clouddebugger2;
use clouddebugger2::Breakpoint;
use clouddebugger2::{Result, Error};
use std::default::Default;
use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
use clouddebugger2::CloudDebugger;
 
// Get an ApplicationSecret instance by some means. It contains the `client_id` and 
// `client_secret`, among other things.
let secret: ApplicationSecret = Default::default();
// Instantiate the authenticator. It will choose a suitable authentication flow for you, 
// unless you replace  `None` with the desired Flow.
// Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about 
// what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and
// retrieve them from storage.
let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate,
                              hyper::Client::new(),
                              <MemoryStorage as Default>::default(), None);
let mut hub = CloudDebugger::new(hyper::Client::new(), auth);
// As the method needs a request, you would usually fill it with the desired information
// into the respective structure. Some of the parts shown here might not be applicable !
// Values shown here are possibly random and not representative !
let mut req = Breakpoint::default();
 
// You can configure optional parameters by calling the respective setters at will, and
// execute the final call using `doit()`.
// Values shown here are possibly random and not representative !
let result = hub.debugger().debuggees_breakpoints_set(req, "debuggeeId")
             .client_version("sed")
             .doit();
 
match result {
    Err(e) => match e {
        // The Error enum provides details about what exactly happened.
        // You can also just use its `Debug`, `Display` or `Error` traits
         Error::HttpError(_)
        |Error::MissingAPIKey
        |Error::MissingToken(_)
        |Error::Cancelled
        |Error::UploadSizeLimitExceeded(_, _)
        |Error::Failure(_)
        |Error::BadRequest(_)
        |Error::FieldClash(_)
        |Error::JsonDecodeError(_, _) => println!("{}", e),
    },
    Ok(res) => println!("Success: {:?}", res),
}

Handling Errors

All errors produced by the system are provided either as Result enumeration as return value of the doit() methods, or handed as possibly intermediate results to either the Hub Delegate, or the Authenticator Delegate.

When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This makes the system potentially resilient to all kinds of errors.

Uploads and Downloads

If a method supports downloads, the response body, which is part of the Result, should be read by you to obtain the media. If such a method also supports a Response Result, it will return that by default. You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making this call: .param("alt", "media").

Methods supporting uploads can do so using up to 2 different protocols: simple and resumable. The distinctiveness of each is represented by customized doit(...) methods, which are then named upload(...) and upload_resumable(...) respectively.

Customization and Callbacks

You may alter the way an doit() method is called by providing a delegate to the Method Builder before making the final doit() call. Respective methods will be called to provide progress information, as well as determine whether the system should retry on failure.

The delegate trait is default-implemented, allowing you to customize it with minimal effort.

Optional Parts in Server-Requests

All structures provided by this library are made to be enocodable and decodable via json. Optionals are used to indicate that partial requests are responses are valid. Most optionals are are considered Parts which are identifiable by name, which will be sent to the server to indicate either the set parts of the request or the desired parts in the response.

Builder Arguments

Using method builders, you are able to prepare an action call by repeatedly calling it's methods. These will always take a single argument, for which the following statements are true.

Arguments will always be copied or cloned into the builder, to make them independent of their original life times.

Structs

AliasContext

An alias to a repo revision.

Breakpoint

Represents the breakpoint specification, status and results.

CloudDebugger

Central instance to access all CloudDebugger related resource activities

CloudRepoSourceContext

A CloudRepoSourceContext denotes a particular revision in a cloud repo (a repo hosted by the Google Cloud Platform).

CloudWorkspaceId

A CloudWorkspaceId is a unique identifier for a cloud workspace. A cloud workspace is a place associated with a repo where modified files can be stored before they are committed.

CloudWorkspaceSourceContext

A CloudWorkspaceSourceContext denotes a workspace at a particular snapshot.

ControllerDebuggeeBreakpointListCall

Returns the list of all active breakpoints for the debuggee. The breakpoint specification (location, condition, and expression 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.

ControllerDebuggeeBreakpointUpdateCall

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 expression 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.

ControllerDebuggeeRegisterCall

Registers the debuggee with the controller service. All agents attached to the same application should call this method with 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 allows the controller service to disable the agent or recover from any data loss. If the debuggee is disabled by the server, the response will have is_disabled set to true.

ControllerMethods

A builder providing access to all methods supported on controller resources. It is not used directly, but through the CloudDebugger hub.

Debuggee

Represents the application to debug. The application may include one or more replicated processes executing the same code. Each of these processes is attached with a debugger agent, carrying out the debugging commands. The agents attached to the same debuggee are identified by using exactly the same field values when registering.

DebuggerDebuggeeBreakpointDeleteCall

Deletes the breakpoint from the debuggee.

DebuggerDebuggeeBreakpointGetCall

Gets breakpoint information.

DebuggerDebuggeeBreakpointListCall

Lists all breakpoints for the debuggee.

DebuggerDebuggeeBreakpointSetCall

Sets the breakpoint to the debuggee.

DebuggerDebuggeeListCall

Lists all the debuggees that the user can set breakpoints to.

DebuggerMethods

A builder providing access to all methods supported on debugger resources. It is not used directly, but through the CloudDebugger hub.

DefaultDelegate

A delegate with a conservative default implementation, which is used if no other delegate is set.

Empty

A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); } The JSON representation for Empty is empty JSON object {}.

ErrorResponse

A utility to represent detailed errors we might see in case there are BadRequests. The latter happen if the sent parameters or request structures are unsound

ExtendedSourceContext

An ExtendedSourceContext is a SourceContext combined with additional details describing the context.

FormatMessage

Represents a message with parameters.

GerritSourceContext

A SourceContext referring to a Gerrit project.

GetBreakpointResponse

Response for getting breakpoint information.

GitSourceContext

A GitSourceContext denotes a particular revision in a third party Git repository (e.g. GitHub).

ListActiveBreakpointsResponse

Response for listing active breakpoints.

ListBreakpointsResponse

Response for listing breakpoints.

ListDebuggeesResponse

Response for listing debuggees.

MethodInfo

Contains information about an API request.

MultiPartReader

Provides a Read interface that converts multiple parts into the protocol identified by RFC2387. Note: This implementation is just as rich as it needs to be to perform uploads to google APIs, and might not be a fully-featured implementation.

ProjectRepoId

Selects a repo using a Google Cloud Platform project ID (e.g. winged-cargo-31) and a repo name within that project.

RegisterDebuggeeRequest

Request to register a debuggee.

RegisterDebuggeeResponse

Response for registering a debuggee.

RepoId

A unique identifier for a cloud repo.

SetBreakpointResponse

Response for setting a breakpoint.

SourceContext

A SourceContext is a reference to a tree of files. A SourceContext together with a path point to a unique revision of a single file or directory.

SourceLocation

Represents a location in the source code.

StackFrame

Represents a stack frame context.

StatusMessage

Represents a contextual status message. The message can indicate an error or informational status, and refer to specific parts of the containing object. For example, the Breakpoint.status field can indicate an error referring to the BREAKPOINT_SOURCE_LOCATION with the message Location not found.

UpdateActiveBreakpointRequest

Request to update an active breakpoint.

UpdateActiveBreakpointResponse

Response for updating an active breakpoint. The message is defined to allow future extensions.

Variable

Represents a variable or an argument possibly of a compound object type. Note how the following variables are represented: 1) A simple variable: int x = 5 { name: "x", value: "5", type: "int" } // Captured variable 2) A compound object: struct T { int m1; int m2; }; T x = { 3, 7 }; { // Captured variable name: "x", type: "T", members { name: "m1", value: "3", type: "int" }, members { name: "m2", value: "7", type: "int" } } 3) A pointer where the pointee was captured: T x = { 3, 7 }; T* p = &x; { // Captured variable name: "p", type: "T*", value: "0x00500500", members { name: "m1", value: "3", type: "int" }, members { name: "m2", value: "7", type: "int" } } 4) A pointer where the pointee was not captured: T* p = new T; { // Captured variable name: "p", type: "T*", value: "0x00400400" status { is_error: true, description { format: "unavailable" } } } The status should describe the reason for the missing value, such as ,, . Note that a null pointer should not have members. 5) An unnamed value: int* p = new int(7); { // Captured variable name: "p", value: "0x00500500", type: "int*", members { value: "7", type: "int" } } 6) An unnamed pointer where the pointee was not captured: int* p = new int(7); int** pp = &p; { // Captured variable name: "pp", value: "0x00500500", type: "int**", members { value: "0x00400400", type: "int*" status { is_error: true, description: { format: "unavailable" } } } } } To optimize computation, memory and network traffic, variables that repeat in the output multiple times can be stored once in a shared variable table and be referenced using the var_table_index field. The variables stored in the shared table are nameless and are essentially a partition of the complete variable. To reconstruct the complete variable, merge the referencing variable with the referenced variable. When using the shared variable table, the following variables: T x = { 3, 7 }; T* p = &x; T& r = x; { name: "x", var_table_index: 3, type: "T" } // Captured variables { name: "p", value "0x00500500", type="T*", var_table_index: 3 } { name: "r", type="T&", var_table_index: 3 } { // Shared variable table entry #3: members { name: "m1", value: "3", type: "int" }, members { name: "m2", value: "7", type: "int" } } Note that the pointer address is stored with the referencing variable and not with the referenced variable. This allows the referenced variable to be shared between pointers and references. The type field is optional. The debugger agent may or may not support it.

Enums
