From 022b35435937d303237520cf7be80137f9cafad6 Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Thu, 7 May 2026 04:43:13 +0000 Subject: [PATCH 1/4] fix(data-integrity): remove session.rollback() calls from ProjectRepository Removed unconditional session.rollback() calls within exception handlers in: - ProjectRepository.create() - NamespacedProjectRepository.create() (IntegrityError handler) - NamespacedProjectRepository.create() (OperationalError handler) - NamespacedProjectRepository.update() - NamespacedProjectRepository.delete() The Unit of Work pattern already handles transaction rollback at the outer layer via its except Exception: session.rollback() handler, making these inner rollbacks redundant. SQLAlchemy automatically invalidates the transaction state when exceptions occur after flush(), preventing partial data from being committed. Removing the redundant rollbacks improves clarity, eliminates potential issues related to exception chaining across retry boundary layers, and aligns repository implementations with explicit transaction boundaries.
