From ed7e29db6a49ec08ac7adfb429a6148642fcfc34 Mon Sep 17 00:00:00 2001 From: Pooya Paridel Date: Wed, 3 Dec 2025 09:38:24 -0800 Subject: [PATCH 01/29] fix(sdk): correct FAILURE_TOLERANCE_EXCEEDED behavior in concurrent operations Fix critical bug where tolerance checks occurred after ALL_COMPLETED check, causing incorrect completion reasons when failure thresholds were exceeded. Changes: - Fix logic ordering in getCompletionReason to check tolerance before completion - Optimize performance by passing failureCount parameter to eliminate redundant calculations - Add failure-threshold-exceeded examples for map and parallel operations - Create comprehensive tests validating FAILURE_TOLERANCE_EXCEEDED behavior - Add context.wait({seconds:1}) after all map/parallel operations in examples The fix ensures operations correctly return FAILURE_TOLERANCE_EXCEEDED when thresholds are exceeded, even if all items have completed execution. ---
