From 26501969c0c627cae4a29a1be26a138273091a4c Mon Sep 17 00:00:00 2001 From: muzahidul-opti Date: Mon, 15 Dec 2025 18:44:30 +0600 Subject: [PATCH 01/12] Refactor: Align Holdout implementation with Swift SDK MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit refactors the holdout implementation to use proper entity classes aligned with the Swift SDK architecture, improving type safety and consistency across the codebase. ## Changes Made ### 1. entities.py - Added Holdout entity class with proper type safety - Implemented Holdout.Status constants matching Swift enum - Added is_activated property (matches Swift's isActivated) - Added get_audience_conditions_or_ids() method for consistent audience handling ### 2. project_config.py - Converted holdout storage from dicts to Holdout entities - Changed global_holdouts from dict to list (matching Swift SDK) - Convert holdout variations to Variation entities during initialization - Updated get_holdouts_for_flag() to return list[entities.Holdout] - Updated get_holdout() to return Optional[entities.Holdout] ### 3. decision_service.py - Updated get_variation_for_holdout() to accept Holdout entities - Use is_activated property instead of dict status check - Use get_audience_conditions_or_ids() for audience evaluation - CRITICAL FIX: Return holdout as experiment field in Decision (was None) - Removed HoldoutDict import, now uses entities.Holdout ### 4. bucketer.py - Unified handling of Experiment and Holdout entities - Removed dict-based branching for holdouts - Use entity properties directly (key, id, trafficAllocation) - Simplified variation lookup (now consistent for all entity types) ## Benefits - **Type Safety**: Holdouts are now proper entity classes, not plain dicts - **Consistency**: Holdouts work exactly like Experiments throughout codebase - **Swift Alignment**: Python SDK matches Swift SDK's holdout architecture - **Bug Fix**: Decision.experiment now returns Holdout entity (enables metadata access) - **Maintainability**: Unified code paths reduce complexity ## Alignment with Swift SDK This implementation now matches Swift SDK's approach where: - Holdout is a proper struct/class conforming to ExperimentCore - isActivated is a computed property - Variations are proper Variation entities - Decision returns the holdout as the experiment field - Global holdouts stored as arrays/lists 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- optimizely/bucketer.py | 51 +++++++-------- optimizely/decision_service.py | 41 ++++++------ optimizely/entities.py | 64 +++++++++++++++++++ optimizely/project_config.py | 112 ++++++++++++++++++--------------- 4 files changed, 170 insertions(+), 98 deletions(-) diff --git a/optimizely/bucketer.py b/optimizely/bucketer.py index ca431012..be198986 100644 --- a/optimizely/bucketer.py +++ b/optimizely/bucketer.py @@ -125,14 +125,10 @@ def bucket( project_config.logger.debug(message) return None, [] - if isinstance(experiment, dict): - # This is a holdout dictionary - experiment_key = experiment.get('key', '') - experiment_id = experiment.get('id', '') - else: - # This is an Experiment object - experiment_key = experiment.key - experiment_id = experiment.id + # Handle both Experiment and Holdout entities (aligned with Swift SDK) + # Both have key and id attributes + experiment_key = experiment.key + experiment_id = experiment.id if not experiment_key or not experiment_key.strip(): message = 'Invalid entity key provided for bucketing.
