Summary

Support per-flag insightsEnabled to control evaluation event collection,
defaulting to true when absent.

Validation

• Full test suite: 77 passed.
• git diff --check passed.

Summary by CodeRabbit

• New Features
  • Feature flags can now control whether evaluation insights are collected. Missing or enabled settings continue to collect insights; explicitly disabled settings do not.
  • Bulk flag reads collect insights only for enabled flags and retain the settings captured when the results were returned.
• Tests
  • Added coverage for insight collection across single and bulk reads, flag updates, and exported flag data.

Confidence Score: 5/5

This PR appears safe to merge; no actionable issues were found.

Summary

Adds per-flag control over evaluation-event collection through insightsEnabled.

• Each feature flag can turn its evaluation events on or off.

Walkthrough

Feature flags now support an optional insightsEnabled setting. Single and bulk evaluations use that setting to control insight event collection. Bulk results retain the enabled flag keys captured when they were created.

Changes: Insight event gating

Layer / File(s)	Summary
Flag setting and single evaluation src/main/java/co/featbit/server/DataModel.java, src/main/java/co/featbit/server/FBClientImp.java, src/test/java/co/featbit/server/InsightsEnabledTest.java	FeatureFlag treats a missing or true insightsEnabled value as enabled, and explicit false as disabled. Single-flag evaluation sends insight events only when enabled. Tests cover these settings and exported data.
Bulk evaluation event gating src/main/java/co/featbit/server/FBClientImp.java, src/main/java/co/featbit/server/Implicits.java, src/test/java/co/featbit/server/InsightsEnabledTest.java	Bulk evaluation passes enabled flag keys to ComplexAllFlagStates, which stores an immutable copy and gates events by key. Tests cover mixed settings and confirm that earlier bulk results retain their captured keys after a flag update.

Merge Risk: Minimal · up to 2ebaa

The change respects per-flag insight settings while preserving collection for older payloads. No concrete merge-blocking issue remains; the suggested event-key assertion is an optional test improvement.

Full details: Title check

Explanation

The title says the PR makes the code respect the flag insights collection setting. The summary shows that FeatureFlag gains an insightsEnabled accessor, and that FBClientImp and ComplexAllFlagStates emit insight events only for flags with insights enabled. The title names the main change. The type prefix "feat:" and the emoji fit the title style, and the title is 48 characters long.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 4 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

What changed in this PR

Adds per-flag control over evaluation event collection in the Java SDK. Flags without insightsEnabled continue collecting events by default.

Changes:

• Gates event collection for individual evaluations and bulk-result reads without changing evaluation results.
• Preserves each bulk result’s collection settings as a snapshot.
• Adds tests for default behavior, per-flag settings, exported data, and setting updates.

File	Description
src/​test/​java/​co/​featbit/​server/​InsightsEnabledTest.java	Tests collection settings, exports, updates, and snapshot behavior.
src/​main/​java/​co/​featbit/​server/​Implicits.java	Applies snapshot collection settings when reading bulk results.
src/​main/​java/​co/​featbit/​server/​FBClientImp.java	Gates individual events and captures settings for bulk results.
src/​main/​java/​co/​featbit/​server/​DataModel.java	Adds insightsEnabled, defaulting to enabled when absent.

Assert the recorded event's flag key for ff-test-string.

75-79: Trivial · Functional Correctness · Quick win

Assert the recorded event's flag key for ff-test-string.

Lines 77 and 79 check only event counts. A change that attaches the ff-test-string read to the ff-test-bool event would keep the count at 1 and still pass. No other assertion in this file checks the key of a recorded event.

Read the recorded InsightTypes.FlagEvent (its supertype is InsightTypes.Event) and assert that its featureFlagKey equals ff-test-string. The FlagEvent keeps its variation list in a private field, so the test needs a package-visible route, such as the event's serialized form. Do not add a production API for this assertion.

Update the assertions in the test around getAllLatestFlagsVariations and
processor.events to inspect the recorded InsightTypes.FlagEvent and verify its
featureFlagKey is ff-test-string. Use an existing package-visible or serialized
representation to read the key without adding a production API, while preserving
the event-count assertions.
