From 44259a00e2fc654e7350ef3e16f9ed2c572fa558 Mon Sep 17 00:00:00 2001 From: jacob314 Date: Mon, 6 Apr 2026 21:30:30 -0700 Subject: [PATCH] Optimize VirtualizedList Checkpoint optimizing virtualized list Fixes for fallback rendering where terminalBuffer=false Change terminalBuffer false back to the default while we fix performance with very large chats. Checkpoint changes to virtualized list. Fix virtualized list NO commit Update ink version. Fix UI snapshot mismatch in MainContent tests and VirtualizedList computation Checkpoint. Optimize scrolling checkpoint Fix tests and resolve remaining issues after rebase - Fixed ToolStickyHeaderRegression scrolling logic. - Added MouseProvider to VirtualizedList test. - Updated snapshots to reflect layout changes in optimized virtual list. Fix flaky plan-mode test by removing model request assertions Fix unit tests by updating expected decisions for tool permissions after rebase use onStaticRender in VirtualizedList Checkpoint VirtualizedListClick Update version Bug fixes. Code review comment fixes. settings.json hack Update version and local tweaks. --- docs/cli/settings.md | 1 + docs/reference/configuration.md | 6 + package-lock.json | 100 +- package.json | 4 +- packages/cli/GEMINI.md | 4 + packages/cli/package.json | 2 +- packages/cli/src/config/settingsSchema.ts | 10 + packages/cli/src/interactiveCli.tsx | 1 + packages/cli/src/ui/App.tsx | 7 +- packages/cli/src/ui/AppContainer.tsx | 13 +- .../src/ui/__snapshots__/App.test.tsx.snap | 90 +- ...-the-frame-of-the-entire-terminal.snap.svg | 21 +- .../ToolConfirmationFullFrame.test.tsx.snap | 18 +- .../src/ui/components/HistoryItemDisplay.tsx | 5 + .../cli/src/ui/components/InputPrompt.tsx | 17 +- .../src/ui/components/MainContent.test.tsx | 2 +- .../cli/src/ui/components/MainContent.tsx | 30 +- .../__snapshots__/MainContent.test.tsx.snap | 21 - .../messages/DenseToolMessage.test.tsx | 111 +- .../components/messages/DenseToolMessage.tsx | 101 +- .../DenseToolMessageInteractivity.test.tsx | 142 +++ .../ui/components/messages/GeminiMessage.tsx | 3 + .../messages/GeminiMessageContent.tsx | 3 + .../components/messages/ToolGroupMessage.tsx | 17 +- .../ui/components/messages/ToolMessage.tsx | 3 + .../components/messages/ToolResultDisplay.tsx | 25 +- .../ToolStickyHeaderRegression.test.tsx | 2 +- .../components/messages/TopicMessage.test.tsx | 96 +- .../ui/components/messages/TopicMessage.tsx | 23 +- .../ToolStickyHeaderRegression.test.tsx.snap | 22 +- .../components/shared/FixedScrollableList.tsx | 330 +++++ .../shared/FixedVirtualizedList.test.tsx | 55 + .../shared/FixedVirtualizedList.tsx | 616 +++++++++ .../src/ui/components/shared/Scrollable.tsx | 28 +- .../ui/components/shared/ScrollableList.tsx | 44 +- .../VirtualizedList.backbuffer.repro.test.tsx | 59 + .../shared/VirtualizedList.fallback.test.tsx | 71 ++ .../shared/VirtualizedList.test.tsx | 355 +++++- .../ui/components/shared/VirtualizedList.tsx | 1098 ++++++++++++++--- .../VirtualizedListInteractivity.test.tsx | 109 ++ .../VirtualizedList.test.tsx.snap | 26 +- packages/cli/src/ui/contexts/MouseContext.tsx | 31 +- packages/cli/src/ui/hooks/useMouseClick.ts | 1 + .../src/ui/hooks/useVirtualizedListClick.ts | 65 + .../src/ui/layouts/ScreenReaderAppLayout.tsx | 4 +- packages/cli/src/ui/utils/MarkdownDisplay.tsx | 1 + ...-search-dialog-google_web_search-.snap.svg | 26 +- ...der-SVG-snapshot-for-a-shell-tool.snap.svg | 26 +- ...pty-slice-following-a-search-tool.snap.svg | 26 +- .../__snapshots__/borderStyles.test.tsx.snap | 27 + .../src/policy/core-tools-mapping.test.ts | 4 +- schemas/settings.schema.json | 7 + test-types.ts | 15 + 53 files changed, 3379 insertions(+), 545 deletions(-) create mode 100644 packages/cli/src/ui/components/messages/DenseToolMessageInteractivity.test.tsx create mode 100644 packages/cli/src/ui/components/shared/FixedScrollableList.tsx create mode 100644 packages/cli/src/ui/components/shared/FixedVirtualizedList.test.tsx create mode 100644 packages/cli/src/ui/components/shared/FixedVirtualizedList.tsx create mode 100644 packages/cli/src/ui/components/shared/VirtualizedList.backbuffer.repro.test.tsx create mode 100644 packages/cli/src/ui/components/shared/VirtualizedList.fallback.test.tsx create mode 100644 packages/cli/src/ui/components/shared/VirtualizedListInteractivity.test.tsx create mode 100644 packages/cli/src/ui/hooks/useVirtualizedListClick.ts create mode 100644 test-types.ts diff --git a/docs/cli/settings.md b/docs/cli/settings.md index ba6e0ed316..af308bc21a 100644 --- a/docs/cli/settings.md +++ b/docs/cli/settings.md @@ -81,6 +81,7 @@ they appear in the UI. | Terminal Buffer | `ui.terminalBuffer` | Use the new terminal buffer architecture for rendering. | `false` | | Use Background Color | `ui.useBackgroundColor` | Whether to use background colors in the UI. | `true` | | Incremental Rendering | `ui.incrementalRendering` | Enable incremental rendering for the UI.
