Conversation
The configure_block_event_tracking_for_anonymous_users flag left two gaps that let anonymous-user events through when it was on: - Client (shouldTrackUser): an active license short-circuited the flag, so licensed EE/cloud instances always tracked anonymous users. Removed the licenseActive bypass so the flag is honored on all instances. - Server (AnalyticsServiceCEImpl.sendEvent): the flag was only checked in sendObjectEvent. Direct sendEvent callers passing an anonymous userId bypassed it. Added a gate on the public sendEvent that blocks anonymous userIds before the x-anonymous-user-id is resolved, keeping the existing sendObjectEvent check for the session-user (signup) path. sendObjectEvent now routes through the extracted private sendEventInternal to avoid a redundant (Redis-backed) flag check on the hot anonymous path. usage-pulse billing/seat metering is intentionally out of scope. Adds unit tests: client shouldTrackUser matrix (incl. the license-bypass regression guard) and a server sendEvent anonymous-block guard.

…S_USERNAME Code-review follow-ups on the anonymous-tracking gate: - sendEvent's anonymous gate now handles featureFlagService.check() errors with onErrorResume, failing closed (event dropped, chain completes) instead of propagating the error into previously fire-and-forget callers like GlobalExceptionHandler. Adds a regression test for the error path. - Align gate style with repo convention: raw if (isBlocked) and plain Mono.empty() (Reactor forbids null onNext, so the defensive forms bought nothing). - Client: use the existing ANONYMOUS_USERNAME constant from userConstants instead of the hardcoded "anonymousUser" literal in shouldTrackUser and its test.

Both new tests cover the blocking paths (flag on, flag error). A third test where the flag resolves to
false(don't block) and asserting thatenqueueis called would confirm the gate works bidirectionally and strengthen confidence that the blocking tests aren't trivially passing.🤖 Prompt for AI Agents

This blocks Segment initialization for anonymous users when configure_block_event_tracking_for_anonymous_users is enabled, which looks correct for analytics tracking.
But usage-pulse still depends on AnalyticsUtil.getAnonymousId() when enableTelemetry && segment.enabled is true. In this new state, segmentAnalytics exists but has no Segment user, so getAnonymousId() can return undefined, and /api/v1/usage-pulse may stop sending anonymousUserId.
Can we also update usage-pulse to fall back to its local FALLBACK_KEY/nanoid() ID when AnalyticsUtil.getAnonymousId() is unavailable? That would preserve the PR’s stated scope that usage-pulse remains separate from Segment analytics blocking. Also could you please verify how does the PR behave in the EE repo?

Hardening: guard Follow-up to the usage-pulse fallback change. Fix: wrap the read/write in a const getOrCreateFallbackAnonymousId = (): string => {
try {
let fallback = localStorage.getItem(FALLBACK_KEY);
if (!fallback) {
fallback = nanoid();
localStorage.setItem(FALLBACK_KEY, fallback);
}
return fallback;
} catch {
// localStorage unavailable (private mode, quota, disabled) — return a
// non-persisted per-call id so the pulse still carries an anonymousUserId.
return nanoid();
}

Description
Makes the
configure_block_event_tracking_for_anonymous_usersfeature flag completely turn off anonymous-user event tracking. Two gaps let anonymous events through when the flag was on:Gap 1 — client license bypass (
app/client/src/ce/sagas/userSagas.tsx)shouldTrackUsershort-circuited on an active license:so licensed EE/cloud instances tracked anonymous users regardless of the flag. Removed the
licenseActivebypass — the flag is now honored on all instances.Gap 2 — ungated direct
sendEventpath (AnalyticsServiceCEImpl)The flag was only checked in
sendObjectEvent. Direct callers ofsendEvent(event, userId, props)with an anonymous userId bypassed it (and that path resolves the anonymous user to the clientx-anonymous-user-id). Added a gate on the publicsendEventthat blocks anonymous userIds before id resolution, and it fails closed if the flag state can't be resolved (drops the event, completes the chain). The existingsendObjectEventcheck is kept (it governs the session-user/signup path, wheresendEventreceives the new user's email rather than"anonymousUser").sendObjectEventnow routes through the extracted privatesendEventInternalto avoid a redundant (Redis-backed) flag check on the hot anonymous path (published-app page views / action executions).Scope
