Fix 'failure to apply changes' when Git diff views are open #1581
Conversation
## Bug Description Multi-file edit operations (`apply_diff` tool) would fail consistently when Git diff views were open in VSCode. The failure occurred before reaching the diff view opening code, indicating the issue was not with tab management as initially suspected. ## Root Cause The bug was caused by **environment context contamination** in `src/core/environment/getEnvironmentDetails.ts`. When Git diff views are open, the environment details gathering code was incorrectly processing non-text tabs: 1. **Improper type casting**: Line 68 used `(tab.input as vscode.TabInputText)?.uri?.fsPath` without filtering, casting all tab inputs as `TabInputText` regardless of their actual type 2. **Processing incompatible tab types**: Git diff tabs have input types like `TabInputTextDiff`, not `TabInputText` 3. **Malformed environment data**: This resulted in unexpected/malformed data being included in the environment context sent to the AI 4. **AI parsing interference**: The contaminated context affected how the AI parsed multi-file `apply_diff` requests, causing them to fail ## Fix Added proper tab type filtering before processing: ```typescript // Before (BROKEN) .map((tab) => (tab.input as vscode.TabInputText)?.uri?.fsPath) // After (FIXED) .filter((tab) => tab.input instanceof vscode.TabInputText) .map((tab) => (tab.input as vscode.TabInputText).uri.fsPath) ``` This matches the correct pattern already used in other parts of the codebase like `DiffViewProvider.ts` and `WorkspaceTracker.ts`. ## Impact - Multi-file edits now work reliably when Git diff views are open - Environment context data is properly filtered and type-safe - Consistent tab processing across the codebase Fixes: #712

WalkthroughA patch was implemented to address failures when applying changes to files with open Git diff views in VSCode. The update filters VSCode tabs to process only valid text document tabs, preventing errors and ensuring changes can be applied regardless of open diff views. Changes

24-29: Consider separating unrelated changes into a different PR.These imports for OpenRouter and Ollama handlers appear unrelated to the main bug fix described in the PR objectives. While they may be valid improvements, mixing them with the critical bug fix makes the PR harder to review and understand.
213-227: Unrelated model fetching logic mixed with bug fix.This OpenRouter/Ollama model fetching logic doesn't appear to be related to the Git diff tab filtering bug described in the PR objectives. Consider moving this to a separate PR focused on model handling improvements.
249-249: Unrelated mode handling change.This comment and logic change for non-existent modes doesn't relate to the main Git diff tab bug fix. While it may be a valid improvement, it should be in a separate PR for clarity.

68-69: Excellent type-safe fix for Git diff tab handling.The filtering approach correctly prevents non-text tabs (like Git diff views) from being processed, which was the root cause of the multi-file edit failures. By filtering first and then casting, you eliminate the risk of undefined values contaminating the environment data.

1-6: Clear and accurate changeset documentation.The changeset properly documents the Git diff view fix with appropriate patch-level versioning and a clear description that matches the core issue being resolved.

Bug Description
apply_difftool would fail consistently when Git diff views were open in VSCode.Root Cause
The bug was caused by environment context contamination in
src/core/environment/getEnvironmentDetails.ts. When Git diff views are open, the environment details gathering code was incorrectly processing non-text tabs:(tab.input as vscode.TabInputText)?.uri?.fsPathwithout filtering, casting all tab inputs asTabInputTextregardless of their actual typeTabInputTextDiff, notTabInputTextapply_diffrequests, causing them to failFix
Added proper tab type filtering before processing:
This matches the correct pattern already used in other parts of the codebase like
DiffViewProvider.tsandWorkspaceTracker.ts.Impact
