From 15e72b8407eccd553d7ad3efc0471d299664424c Mon Sep 17 00:00:00 2001 From: Luis Mendes Date: Sat, 28 Mar 2026 00:52:54 +0000 Subject: [PATCH] fix(events): log full exception details in ReactiveEventBus.emit() error handler Add exc_info=True to the _logger.warning() call in the per-handler exception block of ReactiveEventBus.emit(). The handler already logged error=str(exc) (the exception message text), but omitted the traceback. With exc_info=True structlog now forwards the full traceback to the configured log output, giving developers the diagnostic detail needed to debug subscriber failures in production. Remove the @tdd_expected_fail tag from the traceback scenario in features/tdd_event_bus_exception_swallow.feature so that both TDD scenarios (#988) run as normal regression guards. Fix TDD tags in robot/tdd_e2e_implicit_init.robot: replace incorrect tdd_bug/tdd_bug_1023 tags with the canonical tdd_issue/tdd_issue_1023/ tdd_expected_fail tags so the tdd_expected_fail_listener properly inverts results while bug #1023 remains open.
