Component audit — gpui-native-kit
Full audit of every component ahead of migrating signed onto this kit. Scope: all 7 crates (~21k LOC) — crates/core (30 components), crates/data, crates/editor, crates/layout, plus the foundation crates crates/theme, crates/icons, crates/utils, the facade, and every Cargo.toml feature graph.
Audit criteria, in priority order: no over-engineering, justified function arguments only, no memory leaks, best performance.
Method
Seven parallel read-only audits (one per component group) plus a manual audit of the foundation crates. Every gpui-behavior claim was verified against the pinned zed checkout (504a7f2, per Cargo.lock); every "unused param" claim was backed by workspace-wide greps (crates/, examples/, docs/, tests/). All 15 major findings were re-verified by reading the cited lines. No code was modified; static audit only, no tests run.

Verdict per criterion
| Criterion | Verdict |
|---|---|
| Memory leaks | Near-clean. Zero .detach() on component tasks/subscriptions anywhere in crates/ (grep-verified); tasks stored in fields, self-references via WeakEntity, undo history bounded (100 entries), icon cache bounded, keyed element state pruned by gpui per frame. One real leak: AnchorBoundsRegistry in utils (finding 11), plus one stuck-state bug in resize_handle (finding 10). |
| Over-engineering | A handful of cases: dead defensive machinery (dialog/command_palette bounds plumbing), drifted duplicate painter (scroll_area), pass-through wrappers (markdown), single-use indirection, one speculative persistence API (resizable). |
| Function arguments | ~20 removal candidates found, all with zero-call-site evidence (list below). Feature graphs and module gating are clean (verified per-file against actual imports). |
| Performance | Three systemic hot-path issues (registry clone churn, uncapped caret blink, per-frame O(N) scan in diff_view) plus a recurring debug_selector pattern that allocates every frame in release builds across 7+ sites. |
Major findings (15, all verified)
A. Shared keyed state across sibling instances — root cause: un-namespaced keys
gpui scopes use_keyed_state by the element-id path; a RenderOnce renders under its type name, so two instances of the same component under the same ancestor chain resolve to the same keyed state. Existing tests never catch this class because every test window mounts exactly one instance.
| # | Location | Bug | Fix |
|---|---|---|---|
| 1 | crates/core/src/menu.rs:385,395-396 |
"menu-was-open" / "menu-scroll" / "menu-selection" shared by all Menus in a window → a closed sibling resets the open menu's selection every frame; arrow-key navigation and the selection highlight break with 2+ menus (the gallery ships 5 sibling dropdowns at examples/gallery/src/main.rs:2761-2860). |
Wrap the three calls in window.with_element_namespace(id.clone(), …) — the instance id is already a parameter. context_menu.rs:67-77 is the correct in-repo pattern. |
| 2 | crates/core/src/dropdown_menu.rs:210 |
Same bug: "dropdown-open-origin" bare key. |
Same namespacing. |
| 3 | crates/core/src/slider.rs:143 |
"slider-dragging" bare key → dragging one slider drives both. |
Key by (self.id.clone(), "slider-dragging") — the pattern clipboard.rs:105 already uses. |
| 4 | crates/core/src/scrollbar.rs:144,157 |
Default key ElementId::Name("scrollbar") → two default-keyed scrollbars in one view share drag + autohide state (gallery renders two side by side at main.rs:3231,3257). |
Make the id a required constructor parameter (Scrollbar::vertical(id, handle)) and delete .key(); 6 call sites, most already have ids to pass. |
B. Correctness bugs
| # | Location | Bug | Fix |
|---|---|---|---|
| 5 | crates/core/src/input.rs:2518 (+ :1802) |
utf8_range_to_utf16 has a byte-for-byte copy of utf16_range_to_utf8's body — it never converts UTF-8→UTF-16. Every IME selection/marked-range report is wrong for non-ASCII text (CJK/emoji candidate anchoring). character_index_for_point likewise returns UTF-8 where the trait contract (gpui platform.rs) demands UTF-16. ASCII-only tests cannot catch this. |
Implement the real conversion (encode_utf16().count()); add a non-ASCII regression test. |
| 6 | crates/core/src/combobox.rs:509-518 |
Chevron-open with a selected value refilters using the field text — which is the selected label — so only the selected option is listed. Inconsistent with Select (reopens listing all) and with query-focused open. |
refilter("") when state.selected.is_some() in the chevron branch. |
| 7 | crates/core/src/command_palette.rs:481-510 |
The modal overlay is not deferred — z-order depends on mount position; in the gallery, alerts/toasts paint and receive clicks above the open modal's scrim. Also: the whole panel_bounds Rc<RefCell<Option<Bounds>>> + capture canvas is dead (the scrim is a sibling of the panel, so its mouse handler cannot fire for panel clicks). |
Wrap in deferred(…) like alert.rs:303 / toast.rs:221; delete the bounds machinery, keep a bare canvas for the focus-steal paint. |
| 8 | crates/editor/src/code_view.rs:351 |
Mouse-down maps position with Pixels::ZERO for scroll while mouse-move correctly uses ScrollbarHandle::offset(...).y → clicking after scrolling selects the wrong row. |
Pass the same offset in the down handler. |
| 9 | crates/editor/src/code_view.rs:102-108,137 |
tree-sitter old_tree reused across changed text without Tree::edit() — violates the documented parse contract → stale/garbled highlighting after edits (the gallery's Rust→Large sample toggle triggers it). |
Delete the tree field and the old_tree param of highlight_with_tree; full reparse per change. Reintroduce incremental parsing only when a real consumer needs it. |
| 10 | crates/layout/src/resize_handle.rs:241-268 |
The move handler checks only the stored dragging flag, never event.pressed_button. macOS synthetic drag does not synthesize a MouseUpEvent on outside-release → the seam keeps resizing on hover until the next click (stuck interaction state). |
In the move handler, clear dragging when event.pressed_button != Some(MouseButton::Left). |
C. Memory / performance
| # | Location | Bug | Fix |
|---|---|---|---|
| 11 | crates/utils/src/lib.rs:40-73 |
AnchorBoundsRegistry: app-global HashMap<ElementId, Bounds> that only inserts (never removes), keyed without WindowId (a two-window app can read a same-named element's bounds from the other window), and every record clones the whole map (cx.try_global().cloned() then set_global). Every Button records per frame (button.rs:244-248) → unbounded growth + O(N²)-ish per-frame allocation churn. Consumed by tooltip anchoring. |
Key by (WindowId, ElementId); mutate in place instead of clone-and-set (verify the in-place global-update API in the pinned gpui before rewriting). |
| 12 | crates/core/src/input.rs:2049-2054 |
Caret blink is an uncapped Animation::new(CARET_BLINK_INTERVAL * 2).repeat() → full-window repaint + full text re-shaping at display refresh rate whenever a field is focused (~119 wasted repaints/s at 120 Hz). Violates the repo's own with_max_fps rule. |
.with_max_fps(4.0) (blink period is 1 s; reduce_motion is already handled by gpui). |
| 13 | crates/editor/src/diff_view.rs:332-349 |
widest_row recomputed with an O(document) scan every render (walks every span of every row to feed with_width_from_item) — defeats virtualization on large diffs. |
Compute once in new/set_versions, store in a field. |
| 14 | crates/data/src/tabs.rs:304,367,404 |
Index-keyed element ids on a drag-reorderable strip (dock reorders tabs via move_panel) — violates the stable-domain-id rule; ids permute on every drag, re-keying interaction state, the spinner, and the close button. |
Add a stable per-tab key (Tab::new(key, label) or .key(SharedString)); stable keys already exist at every call site (tab.panel, labels). The index-based on_change/on_close API stays unchanged. |
| 15 | crates/core/src/menu.rs:461 |
Per-frame Vec<MenuItem> deep clone into the on_key_down closure — every label + handler cloned each frame the panel renders. |
One Rc<[MenuItem]> per render; clone the Rc into the closure. |
Param / dead-API removals
All verified by workspace-wide greps with zero call sites outside their own definitions/tests.
Re-checked 2026-11-09 (post-P1): several entries below are superseded by the policy "visual/a11y surface stays even when dead" — see the current P2 plan at the bottom of this document for the authoritative delete/keep split. Notably kept:
PanelDescriptor::icon,DropdownMenu::icon()/.tab_stop(),Alert::icon()/.no_icon(),markdown plain_code(), theaccessibility_labelconvention,ResizeHandle::disabled(),Resizable::sizes()/set_sizes()(test fixture),Separator::orientation(). Still deleted: everything non-UI in the list. Already resolved by review passes:Tab::lead(deleted),ComboboxChangedre-verified still present.

every in-repo caller passes ` |
input copy_selection(_window), caret_visible(&mut self) |

zero external callers on all of them. A uniform library convention — decide once: keep the convention or delete the dead ones. Segmented's id-fallback announcing internal ids ("filter", "theme-demo-mode") should go regardless. |
Over-engineering
dialog.rs:186,236-252— the panel'sstop_propagationfires before the scrim handler can, making the scrim'spanel_bounds.containscheck unreachable → the wholeBoundsCell+ capture canvas is dead machinery. One dismissal mechanism suffices.scroll_area.rs:279-426— a drifted ~150-line copy ofscrollbar.rs's painter (no horizontal axis, no track-click jump, different autohide policy);ScrollAxes::Horizontalis promised but unimplemented, with zero call sites. Delete the copy; compose the realScrollbarelement. This is deletion of a copy, not a new abstraction.input.rs:525,563,1088—Rc<RefCell<Option<InputLayout>>>with a single owner → plainOption<InputLayout>field.input.rs:494-496,2180,2191— two always-SomeOption<Rc<handler>>fields papered over withexpect()s → non-optionalRcfields, delete the expects.input.rs:522,772,809—caret_epoch_started: Option<Instant>is neverNone→ plainInstant.markdown.rs:302-311—CodeBuilderis a pass-through wrapper aroundString→ useString::push_strdirectly.markdown.rs:296-299—TableBuilder::None / Body { rows }is exactlyOption<Vec<MarkdownTableRow>>→ replace with the Option.markdown.rs:662—Event::FootnoteReferencearm is unreachable (ENABLE_FOOTNOTESnot enabled) and contradicts the module doc → delete.avatar.rs:110-189— user style refined twice (base +PixelAvatar), children re-clipped/re-rounded by the base anyway → deletePixelAvatar.style+ itsStyledimpl + duplicate clipping.combobox.rs:329-332—refilterreturns aVec<SharedString>that all five call sites ignore (per-keystroke collect for nothing) → return().combobox.rs:320-333,430-433—refilterdoesn't clamphighlight(the command palette does); the identity round-tripposition(visible[row]) == rowis a bounds check in disguise → clamp inrefilter, thenhighlight.filter(|&row| row < visible.len()).code_view.rs:251-253—.max(0)after.clamp(0, len - 1)is a no-op.code_view.rs:282/diff_view.rs:390—char_width = text_size * 0.62guessed monospace advance, duplicated in two files, drives hit-testing and row width → hoist to a theme metric.segmented.rs:167-171—selectable: Vec<usize> = (0..len).collect()is always0..len→ index math.Cargo.toml(layout) — thedockfeature enablesresizablefor nothing.
Performance (beyond the majors)
Eager format!/to_string for debug_selector
gpui's cfg-gate only disables the method body; arguments allocate every frame including release builds. The correct pattern (already used in clipboard.rs:126, status_dot.rs:97) captures cheap clones and formats inside the closure: .debug_selector(move || format!("{id}-row-{n}")).
Sites: switch.rs:136, field.rs:97-117 (×3), combobox.rs:601,679, command_palette.rs:337,413, tabs.rs:305,409, sidebar.rs:198, code_view.rs:559, diff_view.rs:404,542, input.rs:2044, menu.rs:286 (+ the popover/dialog a11y-label fallbacks).
Per-frame clones/collects in render
segmented.rs:167-171— deep clone of everySegmentedOption<T>+ the0..lenVec, per frame → storeRc<[SegmentedOption<T>]>at construction.select.rs:209-225— whole optionsVeccloned per frame and the trigger re-derives the label inside a closure → computetextonce inrender, move only theSharedStringin.dock.rs:999-1111— per pane per frame for the context menu:pane.clone(),tabs.clone(), three separatepanelscollects → capture one slim tuple Vec, collect once.alert.rs:307—entries().to_vec()clones the entry Vec every render ofAlertsView(borrow-scoping workaround; low priority).code_view.rs:478— the wholeLinecloned per visible row per frame;render_rowonly reads → borrow.menu.rs:286+popover.rs:115,dropdown_menu.rs:205,dialog.rs:158— per-frameSharedString::from(self.id.to_string())fallback labels.
No-op notifies
input.rs:897-916,1253-1261—move_cursor/select_range/drag_select_to/scroll_byalwayscx.notify()+window.notify_text_input_changed(...): pressing Left at offset 0 or wheeling a non-scrollable field triggers a full re-render + IME re-query → early-return when cursor/anchor/scroll are unchanged.
Theme-token violations
Rule: crates/theme owns every color and metric — no raw rgb/rgba/hsla or layout px(...) elsewhere.
button.rs:202-205—hsla(0.0, 0.0, 0.0, 0.0)×4 as a "no border" color → apply the border conditionally instead.dropdown_menu.rs:196—hsla(0.0, 0.0, 0.0, 0.0)→gpui::transparent_black().avatar.rs:187—Hsla { a: 0.16, ..main }+ luminance multipliers1.6/0.95/0.45/0.18→ theme token.separator.rs:72—px(1.)→theme::BORDER_WIDTH(already exists, used by button).menu.rs:472,combobox.rs:666,command_palette.rs:404—px(320.)popup max-height, three copies → one theme metric.tooltip.rs:79,92—px(360.)max width,px(1.)nudge.input.rs:1195,1278+:32—px(1.5)caret width,px(1.)underline,SCROLL_LINES_HEIGHT = 20.0→ theme metrics (next totheme.scrollbar.*).resize_handle.rs:17—KEYBOARD_STEP: f32 = 32.0.window_controls.rs:26,215-220,237—TRAFFIC_LIGHT_PAD,rgba(...)Windows close-hover, caption width.window_frame.rs:13-15—RESIZE_INSET,BORDER_WIDTH.
Input misc
input.rs:1726— every IME composition step pushes undo history; steps >300 ms apart fragment undo → merge unconditionally whilemarked_rangeis active.input.rs:1168—entry.line.paint(...).ok()swallows aResult(failure = invisible text) → log like the shape path atinput.rs:984does.input.rs:820—caret_visible(&mut self)doesn't mutate →&self.
Semantic inconsistencies
alert.rs:264-269—Alerts::clear()drops entries without runningon_dismisshandlers (Toasts::clearruns them viastart_exit→finish_exit) → run the handlers or document the difference.scroll_area.rs:403-407vsscrollbar.rs:348-353— autohide touch-on-drag vs touch-on-hover: two painters, two behaviors → pick one policy (subsumed by the scroll_area consolidation).dock.rs:316-362—close_panelreconciles the displayed right view when its tab closes, butclose_others/close_panedon't → the sidebar can keep showing a closed panel's inspector.combobox.rs:651-658— "No matches" row is near-dead (empty results close the popup); the palette stays open showing "No matches" → pick one semantic.command_palette.rs:336— row ids are list indexes("command", row)for content that reorders every keystroke;Command.idis a stableSharedString→("command", command.id.clone()).shell.rs:283-324— hardcoded element ids not namespaced by the shell id ("sidebar-strip-left"etc.), unlikeDockwhich composes every id fromdock_id→ compose(id, "…").dataa11y sets —sidebar.rs:270-298counts headers in row sets;tree.rs:250-261uses flat-list position/size instead of per-sibling → compute among real siblings.
Clean bills
badge, progress (fps-capped), spinner, status_dot, clipboard, empty_state, context_menu (the namespacing exemplar), list, editor/lib + editor/utils + highlight, layout/lib, theme (engine sound; watchers are app-lifetime; set_preset has one small redundant name lookup), icons (cache bounded, negatives cached), all Cargo.toml feature graphs, and all lifecycle plumbing: no detached tasks/subscriptions anywhere in crates/, WeakEntity used correctly, cx.notify() never from render, overlay state reclaimed by gpui's element-state eviction on dismiss.
Progress
P0 — done (commit 73f7dc3, reviewed)
- Shared keyed-state sweep (findings 1-4): all
use_keyed_statekeys carry the instance id;Scrollbar::vertical/horizontal(id, handle)now require an id,.key()deleted. - Correctness bugs (5, 6, 7, 8, 9, 10, 14): IME UTF-16 conversion fixed, combobox chevron lists all options, palette modal deferred + dead bounds machinery removed, code_view click honors scroll, tree-sitter incremental misuse deleted (
highlight_with_treefolded intohighlight), resize drag ends on capture loss,Tab::new(key, label)with stable element ids. - Regression tests added: two-sibling independence for slider / dropdown / scrollbar, resize capture-loss, multibyte UTF-16 conversions.
P1 — done (in working tree, uncommitted)
- Registry (11): keyed by
(WindowId, ElementId), mutated in place viacx.default_global— no whole-map clone, no cross-window bleed.anchor_boundstakes the window id now. - Caret blink (12):
with_max_fps(4.0);field_benchupdated to probe the capped contract (executor-timer redraw, no next-frame demand). - widest_row (13): cached in
set_rows(called bynew/set_versions). debug_selectorbatch: all eager formats moved into closures (switch, field ×3, combobox ×2, command_palette ×2, tabs ×2, sidebar, code_view, markdown, dock ×2 reusing the.id()format).- Per-frame clone batch: segmented options are
Rc<[SegmentedOption<T>]>(closures capture bumps;selectableVec → index math), select trigger text computed in render, menu/dropdown items passed asRc<[MenuItem]>, alert borrows entries, code_view borrows the rowLine. - Skipped deliberately: the caret animation-id
format!(removing it needs id plumbing throughInputStatefor a ~30-byte alloc — over-engineering). - Decision: registry stays a gpui
Global, not aOnceLock.WindowIds come from a per-Appslotmap, so a process-static map would leak state across tests (everyTestAppContextmints the same early window ids); a Global dies with itsAppand needs no locking.
Validation after P1: cargo check --workspace --all-targets clean, cargo test --workspace 64 binaries 0 failures, cargo fmt --check clean.
P2 — done (in working tree, uncommitted)
Re-verified the whole P2 list against the tree first. Policy recorded in the plan below: visual/a11y surface stays even when dead; only non-UI dead code was deleted.
1a — deleted (non-UI dead API): Slider::value(), ComboboxChanged + its EventEmitter impl + emit, CodeView::language(), CodeView::clear_selection(), Input::submit_on() getter, MarkdownTableCell.column (+ bookkeeping + test assertion), Side::toggle_icon/toggle_label (left values inlined at the call site), render_tab's duplicate selected param (derived from selected_index), register_panel's first-insert-only notify and its cx parameter (all call sites updated), Menu checked field → plain bool, refilter → (). Visibility narrowed: scrollbar_state_key → pub(crate), maximize_on_double_click → private, into_bindings → pub(crate).
1b — kept (UI/a11y surface, dead is fine): PanelDescriptor::icon, DropdownMenu::icon()/.tab_stop(), Alert::icon()/.no_icon(), markdown plain_code(), the whole accessibility_label convention, ResizeHandle::disabled(), Resizable::sizes()/set_sizes(), Separator::orientation(), data closure &mut Window params. One remaining fix moved to follow-ups: Segmented's unlabeled aria fallback announcing internal ids.
2 — over-engineering deletions: dialog's BoundsCell + capture canvas + bounds check deleted (panel stop_propagation is the one mechanism); scroll_area's ~150-line drifted painter deleted — it now composes the real Scrollbar (ScrollbarVisibility, Autohide, and the geometry helpers moved into scrollbar.rs), and ScrollAxes::Both now renders a horizontal thumb too, resolving the promised-but-unimplemented Horizontal; input's Rc<RefCell<Option<InputLayout>>> → plain Option<InputLayout> field, both always-Some handler Options → non-optional (two expects deleted), caret_epoch_started: Option<Instant> → Instant; markdown's CodeBuilder and TableBuilder deleted (String / Option<Vec<_>>), the unreachable footnote arm folded into the render-nothing group; avatar's PixelAvatar.style + Styled impl + duplicate clipping deleted; combobox refilter clamps the highlight and the identity round-trip bounds check became highlight.filter(...); code_view's two no-op .max(0)s deleted; layout Cargo.toml: dock now depends on resize_handle directly instead of resizable.
3 — theme-token hoists: new theme consts: POPUP_MAX_HEIGHT (the three px(320.) popup sites), TOOLTIP_MAX_WIDTH/TOOLTIP_OFFSET, CARET_WIDTH, UNDERLINE_WIDTH, WHEEL_LINE_HEIGHT, RESIZE_KEYBOARD_STEP, WINDOW_RESIZE_INSET, TRAFFIC_LIGHT_PAD (moved out of window_controls; dock/shell/tests import it from the theme), WINDOWS_CAPTION_WIDTH, WINDOWS_CLOSE_HOVER_HEX, MONO_ADVANCE_RATIO (the duplicated 0.62 estimate), PIXEL_AVATAR_* tint/shade factors. Button's Ghost border now paints transparent_black() instead of raw hsla(0,0,0,0) (kept painted for uniform control metrics), dropdown fallback uses transparent_black(), separator hairline uses BORDER_WIDTH.
4 — smaller cleanups: input early-returns when a cursor/selection/wheel change is a no-op (no notify, no IME re-query, no blink-epoch reset); IME pre-edit steps merge into the previous undo entry unconditionally while a composition is active; line.paint errors logged instead of .ok(); caret_visible takes &self; Alerts::clear runs every entry's on_dismiss handler (matches Toasts::clear); dock close_others/close_pane now reconcile the displayed right view (close_panel already did); combobox arms row 0 unconditionally on open, so empty results show "No matches" instead of closing (palette parity); palette rows keyed ("command", command.id) — stable domain ids, not per-keystroke indexes; shell element ids composed from the shell id ((id, "strip"), (id, "strip-drag"), (id, "sidebar-toggle"), (id, "window-controls")); sidebar a11y sets count sibling rows only (headers excluded); tree a11y position/size computed among same-depth siblings in one pass.
Validation after P2: cargo fmt --check clean, cargo check --workspace --all-targets 0 errors/0 warnings, cargo test --workspace 64 binaries 0 failures.
Next step — signed migration
The audit backlog (P0-P2) is complete. Remaining small follow-ups, none blocking: Segmented's unlabeled aria fallback; markdown plain_code()'s double parse if a consumer ever uses it; Separator::orientation() fold if strictness is ever wanted.
Kickoff:
- Clone
signed(git.reya.info/reya/signed) beside this workspace. - Inventory its views against the component list; mark each usage as: direct fit / needs a small adapter / needs a new component.
- Bring missing components in-tree here (per repo rules: components are written here, not ported), then migrate view-by-view.
