| 90 | +## Progress Log |
| 91 | + |
| 92 | +### 2026-02-05 |
| 93 | + |
| 94 | +#### Starting Phase 1 Implementation |
| 95 | + |
| 96 | +Beginning with Step 1.0: Create shared path normalization helper. |
| 97 | + |
| 98 | +### 2026-02-06 |
| 99 | + |
| 100 | +#### Completed Step 1.2: Partial Error Suppression in BaseTool |
| 101 | + |
| 102 | +Implemented the full partial error suppression system in `BaseTool.ts`: |
| 103 | + |
| 104 | +1. **PartialExecutionState discriminated union** (lines 14-27): |
| 105 | + |
| 106 | + - `idle`: Initial state |
| 107 | + - `streaming`: Active streaming with optional lastSeenPath |
| 108 | + - `erroring`: Error state with count, message, firstErrorTime, and isPathValidationError flag |
| 109 | + |
| 110 | +2. **Per-task state isolation via WeakMap** (line 63): |
| 111 | + |
| 112 | + - `private static partialStateByTask = new WeakMap<Task, PartialExecutionState>()` |
| 113 | + - Prevents cross-task state pollution |
| 114 | + - Memory safe - state is GC'd when Task is GC'd |
| 115 | +
|
| 116 | +3. **New methods added**: |
| 117 | +
|
| 118 | + - `getPartialState(task)`: Get or initialize state for task |
| 119 | + - `setPartialState(task, state)`: Update state for task |
| 120 | + - `resetPartialState(task)`: Reset to idle (now takes task parameter) |
| 121 | + - `hasPathStabilized(task, path)`: Updated to use per-task state |
| 122 | + - `notifyPartialError(task, errorMessage, isPathValidationError)`: Error suppression with logging |
| 123 | + - `shouldSkipDueToPathError(task)`: Fast-path guard check |
| 124 | +
|
| 125 | +4. **Updated `handle()` method**: |
| 126 | +
|
| 127 | + - Added fast-path guard at top of partial handling |
| 128 | + - Uses `notifyPartialError()` for error suppression |
| 129 | + - Detects path validation errors via message pattern matching |
| 130 | +
|
| 131 | +5. **Updated all tools to use new signatures**: |
| 132 | + - WriteToFileTool: `hasPathStabilized(task, rawPath)`, `resetPartialState(task)` |
| 133 | + - SearchReplaceTool: Same updates |
| 134 | + - SearchAndReplaceTool: Same updates |
| 135 | + - ApplyDiffTool: Same updates |
| 136 | + - EditFileTool: Same updates |
| 137 | +
|
| 138 | +#### Dependency Upgrades Required |
| 139 | +
|
| 140 | +Initial test runs failed due to pre-existing build issues. Fixed by: |
| 141 | +
|
| 142 | +1. **Pulled `flake.nix` and `flake.lock` from `nix` branch**: |
| 143 | +
|
| 144 | + ```bash |
| 145 | + git checkout nix -- flake.nix flake.lock |
| 146 | + ``` |
| 147 | + |
| 148 | +2. **Updated `package.json` (root)**: |
| 149 | + |
| 150 | + - `turbo`: ^2.5.6 → ^2.8.3 |
| 151 | + - `node` (engines): 20.19.2 → 20.20.0 |
| 152 | + |
| 153 | +3. **Updated `src/package.json`**: |
| 154 | + |
| 155 | + - `node` (engines): 20.19.2 → 20.20.0 |
| 156 | + |
| 157 | +4. **Updated `writeToFileTool.spec.ts`**: |
| 158 | + - Added `normalizeToolPath` to the `pathUtils` mock |
| 159 | + - Updated partial error handling test to reflect new error suppression behavior |
| 160 | + - Added proper `resetPartialState(mockCline)` call in `beforeEach` |
| 161 | + |
| 162 | +After upgrades, all tests pass: |
| 163 | + |
| 164 | +- 370 test files passed (4 skipped) |
| 165 | +- 5461 tests passed (47 skipped) |
| 166 | +- 0 failures |
| 167 | + |
| 168 | +#### Completed Step 1.3 & 1.4: Added Tests |
| 169 | + |
| 170 | +Created two new test files: |
| 171 | + |
| 172 | +1. **`src/utils/__tests__/pathUtils.spec.ts`** (26 tests): |
| 173 | + |
| 174 | + - Valid path tests (simple, nested, ./, normalized, absolute within workspace) |
| 175 | + - Invalid path tests (../ traversal, absolute paths outside workspace) |
| 176 | + - Edge cases (empty segments, dots, spaces, special characters) |
| 177 | + - Specific test for issue #11208 (`/plans` path) |
| 178 | + |
| 179 | +2. **`src/core/tools/__tests__/BaseTool.spec.ts`** (21 tests): |
| 180 | + - Partial state management (initialization, isolation, reset) |
| 181 | + - `hasPathStabilized()` behavior |
| 182 | + - `notifyPartialError()` suppression logic |
| 183 | + - `shouldSkipDueToPathError()` fast-path guard |
| 184 | + - Integration tests for `handle()` error suppression |
| 185 | +
|
| 186 | +All 47 new tests pass: |
| 187 | +
|
| 188 | +```bash |
| 189 | +cd src && pnpm vitest run utils/__tests__/pathUtils.spec.ts core/tools/__tests__/BaseTool.spec.ts |
| 190 | +# Test Files 2 passed (2) |
| 191 | +# Tests 47 passed (47) |
| 192 | +``` |
