Custom telemetry namespace (TelemetryOptions)

Problem: redhat.telemetry.enabled was the only way to gate telemetry in this library. Extensions with their own telemetry pipeline had no way to control it independently their setting was always tied to the Red Hat namespace.

Solution: getRedHatService() now accepts an optional TelemetryOptions second argument. When a caller supplies telemetryNamespace, the library uses <namespace>.telemetry.enabled as the sole gate for that pipeline. The two pipelines are fully independent — neither setting affects the other.


What changed

New TelemetryOptions interface (src/common/api/telemetryOptions.ts)
Four optional fields: telemetryNamespace, optInMessage, privacyStatementUrl, optOutInstructionsUrl

New CustomVSCodeSettings class (src/common/vscode/settings.ts)
Reads/writes <namespace>.telemetry.enabled only. Refactored the shared VS Code level logic into a standalone getVSCodeTelemetryLevel() function used by both settings classes.

AbstractRedHatServiceProvider wired up (src/common/vscode/redhatServiceInitializer.ts)
Constructor now accepts options?: TelemetryOptions and selects CustomVSCodeSettings or VSCodeSettings accordingly. The settings field is retyped to TelemetrySettings (interface) rather than the concrete class.

Config watcher scoped to the right namespace
onDidChangeTelemetryEnabled now accepts an optional configNamespace. When a custom namespace is active, it watches only that namespace and ignores both redhat.telemetry and the global telemetry section. Default behavior (watch both) is unchanged when no namespace is passed.

Per-namespace opt-in lock file
The popup lock file is <namespace>.optin.json when a custom namespace is active, redhat.optin.json otherwise. This prevents opt-in dialogs from interfering across pipelines.

Configurable dialog text
buildOptInMessage() (extracted, exported for testing) builds the opt-in dialog string from options.optInMessage, options.privacyStatementUrl, and options.optOutInstructionsUrl, falling back to the Red Hat defaults for any omitted field.

getRedHatService() signature updated in both entry points
src/node/index.ts and src/webworker/index.ts each accept options?: TelemetryOptions and forward it to their provider constructors. TelemetryOptions is re-exported from all three entry points (src/index.ts, src/node/index.ts, src/webworker/index.ts).

TelemetrySettings interface extended
Added updateTelemetryEnabledConfig(value: boolean): Thenable<void> so the dialog's accept/deny handler can write through the interface without knowing which settings class is active.


Tests

src/tests/vscode/customVSCodeSettings.test.ts — covers isTelemetryEnabled, isTelemetryConfigured, updateTelemetryEnabledConfig, and confirms the custom namespace is unaffected by redhat.telemetry.enabled or a global telemetryLevel: off.

src/tests/vscode/redhatServiceInitializer.test.ts — covers onDidChangeTelemetryEnabled (custom namespace fires only on its own config change; default behavior preserved) and buildOptInMessage (custom text, custom URLs, fallback to Red Hat defaults).


Downstream usage requirement

Callers must declare <namespace>.telemetry.enabled as a boolean in contributes.configuration in their package.json. If they omit it, VS Code returns undefined for the key, which defaults to false and silently disables the pipeline.


No breaking changes

When options is not passed, every code path falls through to the existing behavior. No existing callers need to change.

…essage

- Add customEnablementParam and customOptInMessage options to TelemetryOptions
- Fix custom namespace telemetry incorrectly ignoring VS Code global telemetryLevel
- Refactor: remove instanceof leak, deduplicate config calls, remove magic strings
- Add missing CustomVSCodeSettings import in redhatServiceInitializer
…isTelemetryConfigured

- Add getTelemetryLevel() suite: standard VS Code client, Codium privacy default,
  telemetry.telemetryLevel override, legacy enableTelemetry/enableCrashReporter flags
- Add isTelemetryConfigured() cases for all six VS Code scope values
  (workspaceValue, workspaceFolderValue, globalLanguageValue,
  workspaceLanguageValue, workspaceFolderLanguageValue)
- Use vi.hoisted() for mockEnv so the vi.mock factory can reference it
- Move mockEnv restore to afterEach to guard against mid-test throws

📝 Walkthrough

Summary by CodeRabbit

  • New Features

    • Added support for configuring an independent telemetry namespace.
    • Added customizable opt-in messaging, privacy statements, and opt-out instructions.
    • Telemetry preferences can now be stored independently from global settings.
    • Added configuration support across Node and web worker integrations.
  • Documentation

    • Added setup and usage guidance for configuring independent telemetry.
  • Tests

    • Added coverage for custom settings, configuration changes, and opt-in messaging.

Walkthrough

The PR adds TelemetryOptions for independent telemetry namespaces. It adds namespaced VS Code settings, opt-in persistence, custom messages and URLs, provider wiring, tests, and README usage documentation.

Changes

Independent telemetry namespace support

Layer / File(s) Summary
Telemetry options and provider API
src/common/api/telemetryOptions.ts, src/common/api/settings.ts, src/index.ts, src/node/index.ts, src/webworker/index.ts
The API defines optional telemetry namespace and opt-in settings. Node and Web Worker getRedHatService functions accept and forward these options.
Namespaced settings and service behavior
src/common/vscode/settings.ts, src/common/vscode/redhatServiceInitializer.ts
VS Code settings support custom namespaces. Service listeners, opt-in files, and opt-in messages use the configured namespace and options.
Behavior validation and usage documentation
src/tests/vscode/*, README.md
Tests cover namespaced settings, telemetry levels, configuration listeners, and message fallbacks. The README documents configuration and usage.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to b1ea8

The change adds independently configurable telemetry settings and opt-in text while preserving default behavior; no actionable merge-blocking risk remains.

Comment thread src/common/vscode/redhatServiceInitializer.ts
Appending '?from=' as raw text breaks URLs that already carry a query
string (the value becomes part of the last param) and misplaces the
parameter when a fragment is present. Use URL.searchParams.set() so the
param is encoded and positioned correctly in all cases.

CustomVSCodeSettings.isTelemetryEnabled() does not check getTelemetryLevel() != "off", unlike VSCodeSettings. This means if a user sets telemetry.telemetryLevel: off in VS Code (the system-wide "do not track me" signal), the custom pipeline ignores it and keeps sending data.

The getTelemetryLevel() method is already on this class and returns the correct global value — it is just not consulted in isTelemetryEnabled().

Either:

  1. Gate on the global level here too (like VSCodeSettings does): return getVSCodeTelemetryLevel() !== 'off' && ...
  2. Or add an explicit opt-out flag to TelemetryOptions (e.g. ignoreGlobalTelemetryLevel?: boolean) so callers consciously choose to bypass it

Commit b1ea852 fixed the CodeRabbit URL-construction comment but introduced a throw path. new URL(privacyUrl) throws TypeError for relative URLs or malformed strings (e.g. privacyStatementUrl: '/privacy'). Since openTelemetryOptInDialogIfNeeded() is fire-and-forget (line 77, no await), this becomes an unhandled promise rejection that can crash the extension host.

Wrap in try/catch and fall back to string concatenation, or validate the URL early in the constructor.

const optOutUrl = options?.optOutInstructionsUrl ?? OPT_OUT_INSTRUCTIONS_URL;
const privacyUrlWithFrom = new URL(privacyUrl);
privacyUrlWithFrom.searchParams.set('from', extensionId);
return `Help Red Hat improve its extensions by allowing them to collect usage data.

When telemetryNamespace is provided but optInMessage is omitted, this falls back to "Help Red Hat improve its extensions..." — which is misleading for non-Red Hat consumers.

For example { telemetryNamespace: 'ibm', privacyStatementUrl: 'https://ibm.com/privacy' } produces a dialog saying "Help Red Hat improve" with an IBM privacy link.

Consider either:

  1. Requiring optInMessage when telemetryNamespace is set (throw or log a warning if absent)
  2. Making the brand name a TelemetryOptions field so the default message can use it

export class CustomVSCodeSettings implements TelemetrySettings {
private readonly configKey: string;

constructor(private readonly telemetryNamespace: string) {

No validation on telemetryNamespace. An empty string produces malformed config keys (.telemetry.enabled, section .telemetry). A guard like if (!telemetryNamespace) throw ... in the constructor would prevent silent misbehavior.
