From 5b1ca51ec001cbff3ef800919c4aea5de5d7ab3c Mon Sep 17 00:00:00 2001 From: Daniel <57051444+daniel-lxs@users.noreply.github.com> Date: Sat, 5 Jul 2025 10:28:16 -0500 Subject: [PATCH] feat: optimize file listing when maxWorkspaceFiles is 0 (#5421) - Add early return in listFiles() when limit is 0 to avoid unnecessary file scanning - Update getEnvironmentDetails() to show appropriate message when workspace files context is disabled - Add test coverage for maxWorkspaceFiles=0 scenario - Clean up test files to remove unnecessary mocking complexity This optimization improves performance when users set maxWorkspaceFiles to 0, completely bypassing file system operations. --- .../__tests__/getEnvironmentDetails.spec.ts | 13 ++ src/core/environment/getEnvironmentDetails.ts | 26 ++-- src/services/glob/__mocks__/list-files.ts | 7 +- .../glob/__tests__/list-files.spec.ts | 129 ++---------------- src/services/glob/list-files.ts | 5 + 5 files changed, 52 insertions(+), 128 deletions(-) diff --git a/src/core/environment/__tests__/getEnvironmentDetails.spec.ts b/src/core/environment/__tests__/getEnvironmentDetails.spec.ts index f7e63d86c6..57e7fe0f27 100644 --- a/src/core/environment/__tests__/getEnvironmentDetails.spec.ts +++ b/src/core/environment/__tests__/getEnvironmentDetails.spec.ts @@ -190,6 +190,19 @@ describe("getEnvironmentDetails", () => { expect(listFiles).not.toHaveBeenCalled() }) + it("should skip file listing when maxWorkspaceFiles is 0", async () => { + mockProvider.getState.mockResolvedValue({ + ...mockState, + maxWorkspaceFiles: 0, + }) + + const result = await getEnvironmentDetails(mockCline as Task, true) + + expect(listFiles).not.toHaveBeenCalled() + expect(result).toContain("Workspace files context disabled") + expect(formatResponse.formatFilesList).not.toHaveBeenCalled() + }) + it("should include recently modified files if any", async () => { ;(mockCline.fileContextTracker!.getAndClearRecentlyModifiedFiles as Mock).mockReturnValue([ "modified1.ts", diff --git a/src/core/environment/getEnvironmentDetails.ts b/src/core/environment/getEnvironmentDetails.ts index 9120b5e8c7..fa0bc7bb82 100644 --- a/src/core/environment/getEnvironmentDetails.ts +++ b/src/core/environment/getEnvironmentDetails.ts @@ -252,18 +252,24 @@ export async function getEnvironmentDetails(cline: Task, includeFileDetails: boo details += "(Desktop files not shown automatically.
