From ff8640501fba210fee0618dd112b3462e904e3bd Mon Sep 17 00:00:00 2001 From: Ed_ Date: Wed, 1 Jul 2026 22:07:15 -0400 Subject: [PATCH] fix(render_task_dag_panel): prevent AttributeError on dict leftover tickets Test_undo_redo_lifecycle was failing in tier-3 batch because: 1. The prior test (test_mma_concurrent_tracks_sim) leaves dict-typed ticket entries in app.active_tickets (via the Add Ticket form path that creates Ticket dicts, not Ticket dataclass instances). 2. render_task_dag_panel iterates app.active_tickets and does t.id, t.status, t.target_file on each element. A dict element raises AttributeError on .id, and imgui-node-editor's internal state becomes unbalanced, throwing 'Missing PopID()' on subsequent frames. 3. The ImGui assertion kills the render loop, _handle_history_logic stops firing, no snapshot push happens, undo stack stays empty, undo test fails with can_undo=False. Fix in src/gui_2.py: - Pre-filter app.active_tickets to a local _tickets list that drops non-Ticket elements (no .id and .status attrs). The unfiltered list is still authoritative for tests that read it via api_hooks. - Replace app.active_tickets references in the for-loops with _tickets. - Wrap the entire body in try/except as a second line of defense for any other ImGui state corruption. Drain to _last_request_errors. Fix in src/app_controller.py: - btn_reset now also syncs app.temperature/top_p/max_tokens/ui_ai_input from the controller's reset values. Without this, prior test setattr calls leave stale app attrs that the snapshot push captures as the 'reset' baseline. - btn_reset also clears app.active_tickets, app.active_track, app.proposed_tracks, app.mma_streams. Same reason: prior tests in the same live_gui session pollute these, and the next test inherits the dirty state. Verified: all 3 test_undo_redo_sim tests (test_undo_redo_lifecycle, test_undo_redo_discussion_mutation, test_undo_redo_context_mutation) now pass in tier-3 batch (previously only passed in isolation). The single remaining tier-3 failure is test_visual_sim_mma_v2 which fails because the gemini_cli mock service doesn't respond with proposed tracks in batch context - unrelated to the render loop. --- src/app_controller.py | 25 +++- src/gui_2.py | 303 +++++++++++++++++++++++------------------- 2 files changed, 185 insertions(+), 143 deletions(-) diff --git a/src/app_controller.py b/src/app_controller.py index e2e6f8ae..efdf953d 100644 --- a/src/app_controller.py +++ b/src/app_controller.py @@ -3954,10 +3954,18 @@ class AppController: self.temperature = 0.0 self.top_p = 1.0 self.max_tokens = 8192 - # Clear undo/redo history so the next session starts fresh.
