159 | - Cross traces at 90° when traces must cross on adjacent layers
160 |
161 | 4. Return Path Management:
162 | - Ensure continuous return path under the signal
163 | - Avoid reference plane splits under high-speed signals

1 | # Changelog - October 26, 2025
2 |
3 | ## 🎉 Major Updates: Testing, Fixes, and UI Auto-Launch
4 |
5 | **Summary:** Complete testing of KiCAD MCP server, critical bug fixes, and new UI auto-launch feature for seamless visual feedback.
6 |
7 | ---
8 |
9 | ## 🐛 Critical Fixes
10 |
11 | ### 1. Python Environment Detection (src/server.ts)
12 | **Problem:** Server hardcoded to use system Python, couldn't access venv dependencies
13 |
14 | **Fixed:**
15 | - Added `findPythonExecutable()` function with platform detection
16 | - Auto-detects virtual environment at `./venv/bin/python`
17 | - Falls back to system Python if venv not found
18 | - Cross-platform support (Linux, macOS, Windows)
19 |
20 | **Files Changed:**
21 | - `src/server.ts` (lines 32-70, 153)
22 |
23 | **Impact:** ✅ `kicad-skip` and other venv packages now accessible
24 |
25 | ---
26 |
27 | ### 2. KiCAD Path Detection (python/utils/platform_helper.py)
28 | **Problem:** Platform helper didn't check system dist-packages on Linux
29 |
30 | **Fixed:**
31 | - Added `/usr/lib/python3/dist-packages` to search paths
32 | - Added `/usr/lib/python{version}/dist-packages` for version-specific installs
33 | - Now finds pcbnew successfully on Ubuntu/Debian systems
34 |
35 | **Files Changed:**
36 | - `python/utils/platform_helper.py` (lines 82-89)
37 |
38 | **Impact:** ✅ pcbnew module imports successfully from system installation
39 |
40 | ---
41 |
42 | ### 3. Board Reference Management (python/kicad_interface.py)
43 | **Problem:** After opening project, board reference not properly updated
44 |
45 | **Fixed:**
46 | - Changed from `pcbnew.GetBoard()` (doesn't work) to `self.project_commands.board`
47 | - Board reference now correctly propagates to all command handlers
48 |
49 | **Files Changed:**
50 | - `python/kicad_interface.py` (line 210)
51 |
52 | **Impact:** ✅ All board operations work after opening project
53 |
54 | ---
55 |
56 | ### 4. Parameter Mapping Issues
57 |
58 | #### open_project Parameter Mismatch (src/tools/project.ts)
59 | **Problem:** TypeScript expected `path`, Python expected `filename`
60 |
61 | **Fixed:**
62 | - Changed tool schema to use `filename` parameter
63 | - Updated type definition to match
64 |
65 | **Files Changed:**
66 | - `src/tools/project.ts` (line 33)
67 |
68 | #### add_board_outline Parameter Structure (src/tools/board.ts)
69 | **Problem:** Nested `params` object, Python expected flattened parameters
70 |
71 | **Fixed:**
72 | - Flatten params object in handler
73 | - Rename `x`/`y` to `centerX`/`centerY` for Python compatibility
74 |
75 | **Files Changed:**
76 | - `src/tools/board.ts` (lines 168-185)
77 |
78 | **Impact:** ✅ Tools now work correctly with proper parameter passing
79 |
80 | ---
81 |
82 | ## 🚀 New Features
83 |
84 | ### UI Auto-Launch System
85 |
86 | **Description:** Automatic KiCAD UI detection and launching for seamless visual feedback

273 | ## 🚀 User Impact
274 |
275 | ### Before Today
276 | ```
277 | User: "Create a board"
278 | → Creates project file
279 | → User must manually open in KiCAD
280 | → User must manually reload after each change
281 | ```
282 |
283 | ### After Today
284 | ```
285 | User: "Create a board"
286 | → Creates project file
287 | → Auto-launches KiCAD (optional)
288 | → KiCAD auto-detects changes and prompts reload
289 | → Seamless visual feedback!
290 | ```
291 |

293 |
294 | ## 📝 Migration Notes
295 |
296 | ### For Existing Users
297 | 1. **Rebuild required:** `npm run build`
298 | 2. **Restart MCP server** to load new features
299 | 3. **Optional:** Add `KICAD_AUTO_LAUNCH=true` to config for automatic launching
300 | 4. **Optional:** Install `inotify-tools` on Linux for file monitoring (future enhancement)
301 |
302 | ### Breaking Changes
303 | None - all changes are backward compatible
304 |
305 | ### New Dependencies
306 | - Python: None (all in stdlib)
307 | - Node.js: None (existing SDK)
308 |
309 | ---
310 |
311 | ## 🐛 Bug Tracker
312 |
313 | ### Fixed Today
314 | - [x] Python venv not detected
315 | - [x] pcbnew import fails on Linux
316 | - [x] Board reference not updating after open_project
317 | - [x] Parameter mismatch in open_project
318 | - [x] Parameter structure in add_board_outline
319 |
320 | ### Remaining Issues
321 | - [ ] get_board_info KiCAD 9.0 API compatibility
322 | - [ ] Component library path detection
323 | - [ ] Routing operations implementation
324 |
325 | ---
326 |
327 | ## 🎓 Lessons Learned
328 |
329 | 1. **Process spawning:** Background processes need proper detachment (CREATE_NEW_PROCESS_GROUP on Windows, start_new_session on Unix)
330 |
331 | 2. **Parameter mapping:** TypeScript tool schemas must exactly match Python expectations - use transform functions when needed
332 |
333 | 3. **Board lifecycle:** KiCAD's pcbnew module doesn't provide a global GetBoard() - must maintain references explicitly
334 |
335 | 4. **Platform detection:** Each OS has different process management tools (pgrep, tasklist) - must handle gracefully
336 |
337 | 5. **Virtual environments:** Auto-detecting venv dramatically improves DX - no manual PYTHONPATH configuration needed

378 | ## 🔧 Session 2: Bug Fixes & KiCAD 9.0 Compatibility (2025-10-26 PM)
379 |
380 | ### Issues Fixed
381 |
382 | **1. KiCAD Process Detection Bug** ✅
383 | - **Problem:** `check_kicad_ui` was detecting MCP server's own processes
384 | - **Root Cause:** Process search matched `kicad_interface.py` in process names
385 | - **Fix:** Added filters to exclude MCP server processes, only match actual KiCAD binaries
386 | - **Files:** `python/utils/kicad_process.py:31-61, 196-213`
387 | - **Result:** UI auto-launch now works correctly
388 |
389 | **2. Missing Command Mapping** ✅
390 | - **Problem:** `add_board_text` command not found
391 | - **Root Cause:** TypeScript tool named `add_board_text`, Python expected `add_text`
392 | - **Fix:** Added command alias in routing dictionary
393 | - **Files:** `python/kicad_interface.py:150`
394 | - **Result:** Text annotations now work
395 |
396 | **3. KiCAD 9.0 API - set_board_size** ✅
397 | - **Problem:** `BOX2I_SetSize` argument type mismatch
398 | - **Root Cause:** KiCAD 9.0 changed SetSize to take two parameters instead of VECTOR2I
399 | - **Fix:** Try new API first, fallback to old API for compatibility
400 | - **Files:** `python/commands/board/size.py:44-57`
401 | - **Result:** Board size setting now works on KiCAD 9.0
402 |
403 | **4. KiCAD 9.0 API - add_text rotation** ✅
404 | - **Problem:** `EDA_TEXT_SetTextAngle` expecting EDA_ANGLE, not integer
405 | - **Root Cause:** KiCAD 9.0 uses EDA_ANGLE class instead of decidegrees
406 | - **Fix:** Create EDA_ANGLE object, fallback to integer for older versions
407 | - **Files:** `python/commands/board/outline.py:282-289`
408 | - **Result:** Text annotations with rotation now work
409 |
410 | ### Testing Results
411 |
412 | **Complete End-to-End Workflow:** ✅ **PASSING**
413 |
414 | Created test board with:
415 | - ✅ Project creation and opening
416 | - ✅ Board size: 100mm x 80mm
417 | - ✅ Rectangular board outline
418 | - ✅ 4 mounting holes (3.2mm) at corners
419 | - ✅ 2 text annotations on F.SilkS layer
420 | - ✅ Project saved successfully
421 | - ✅ KiCAD UI launched with project
422 |
