kschappell	2c1f37bb7f	Add proprietary licence	2025-11-28 19:16:10 +00:00
kschappell	58ccc5bc6f	Fix CI tests and speed up integration tests ... - Speed up simulation 10x for integration tests (reduces test time from 10+ minutes to ~2.5 minutes) - Add small delays between TCP commands in tests for reliability - Fix Gitea CI release job (use gitea.ref instead of github.ref) - Revert write() error-check that was consuming query responses	2025-11-26 11:21:49 +00:00
kschappell	c2310ab93d	Remove confusing pause/clear chart buttons from dashboard ... The physics engine runs continuously, so pausing charts was misleading - users might think the simulation stopped when it didn't. Charts now always update automatically. Also fix Streamlit deprecation warnings by replacing use_container_width with width parameter (will be removed after 2025-12-31).	2025-11-21 12:27:53 +00:00

kschappell	4f6f3be7a6	Fix TempCo integration tests with thread-based async server ... Redesign integration test architecture to eliminate async/sync deadlock: - Run SimulationServer in dedicated background thread with own event loop - Rewrite TempCo tests as fully synchronous (no @pytest.mark.asyncio) - Add ServerThread fixture in tests/integration/conftest.py - Fix Unicode encoding errors (replace deg, mu, +/- with ASCII) - Optimize temperature points for faster settling (23C, 25C, 27C) All 3 TempCo integration tests now passing in ~5 minutes total.	2025-10-12 17:59:48 +00:00
kschappell	9d16480503	Fix SCPI server response handling and add TEMP:RAMP command ... - Revert server to only send responses for non-empty strings Per SCPI protocol: successful commands with no output send nothing - Add TEMP:RAMP command support to thermal chamber simulator - Fixes test_multiple_commands and test_physics_engine_integration TCP server integration tests now passing (8/8). TempCo integration tests still need work due to async/sync mixing.	2025-10-09 15:25:08 +00:00
kschappell	3b2c60178f	WIP: Use thread pool executor for integration tests ... Move synchronous test execution to thread pool executor to avoid blocking the async event loop.
