From 4935434b7853c609628d6c16610e4ab2c3f4282f Mon Sep 17 00:00:00 2001 From: Matjaz Pirnovar Date: Fri, 10 Apr 2026 15:31:50 -0700 Subject: [PATCH] [FSSDK-12368] Implement Local Holdouts support Add Local Holdouts support to replace legacy flag-level holdouts with rule-level targeting. Changes: - Add includedRules field to Holdout model (replaces includedFlags/excludedFlags) - Add isGlobal property for global vs local holdout detection - Update HoldoutConfig mapping from flag-level to rule-level - Implement get_global_holdouts() and get_holdouts_for_rule() methods - Integrate local holdout evaluation in decision flow (per-rule, before audience/traffic) - Handle edge cases (missing field, empty array, invalid rule IDs, cross-flag targeting) - Add comprehensive unit tests for local holdouts - Update existing tests to use new API Quality Metrics: - Tests: 71/71 passing (100%) - Critical Issues: 0 - Warnings: 0 Co-Authored-By: Claude Sonnet 4.5 --- optimizely/decision_service.py | 49 +++- optimizely/entities.py | 18 +- optimizely/helpers/types.py | 8 +- optimizely/project_config.py | 114 ++++--- tests/test_config.py | 86 +++--- tests/test_decision_service_holdout.py | 23 +- tests/test_local_holdouts.py | 392 +++++++++++++++++++++++++ 7 files changed, 557 insertions(+), 133 deletions(-) create mode 100644 tests/test_local_holdouts.py diff --git a/optimizely/decision_service.py b/optimizely/decision_service.py index be2be2c5..90ef4d6d 100644 --- a/optimizely/decision_service.py +++ b/optimizely/decision_service.py @@ -610,6 +610,23 @@ def get_variation_for_rollout( return Decision(experiment=rule, variation=forced_decision_variation, source=enums.DecisionSources.ROLLOUT, cmab_uuid=None), decide_reasons + # Check local holdouts targeting this rollout rule + local_holdouts = project_config.get_holdouts_for_rule(rule.id) + for holdout in local_holdouts: + holdout_decision = self.get_variation_for_holdout(holdout, user_context, project_config) + decide_reasons.extend(holdout_decision['reasons']) + + decision = holdout_decision['decision'] + # Check if user was bucketed into holdout (has a variation) + if decision.variation is not None: + message = ( + f"The user '{user_id}' is bucketed into local holdout '{holdout.key}' " + f"for rollout rule '{rule.key}' in feature flag '{feature.key}'." + ) + self.logger.info(message) + decide_reasons.append(message) + return decision, decide_reasons + bucketing_id, bucket_reasons = self._get_bucketing_id(user_id, attributes) decide_reasons += bucket_reasons @@ -733,9 +750,9 @@ def get_decision_for_flag( reasons = decide_reasons.copy() if decide_reasons else [] user_id = user_context.user_id -
