From 9370d024eb43eb166c153d4ea2005fa9458efab9 Mon Sep 17 00:00:00 2001 From: Mike Bridge Date: Fri, 24 Apr 2026 15:47:30 -0600 Subject: [PATCH 1/8] perf(datasource-editor): fix typing lag and scrambling in form fields MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Typing into any Dataset Editor text field (Settings → Basic Description, column descriptions, metric labels, SQL expressions) was visibly slow on realistic datasets because every keystroke re-rendered all seven tabs' contents and ran synchronous O(n) validation inside the setState callback. On fast typing or East-Asian IME input, characters landed in the DOM in the order renders finished rather than the order typed, manifesting as "scrambled" input. See sc-104866 for the full diagnosis. Four coordinated changes in two files: 1. Debounce validate + flush on blur. Validation (duplicate-name checks, currency format, folder consistency) is moved off the keystroke hot path via lodash debounce (300 ms window). A new flushValidation method is exposed as onBlur on the DatasourceContainer wrapper so focus leaving any field flushes pending validation synchronously, keeping the Save-button error gate accurate (errors.length > 0 disables save). componentWillUnmount cancels the pending invocation to avoid setState-on-unmounted warnings. 2. Lazy-mount hidden tabs via destroyInactiveTabPane so only the visible tab's children are mounted. Eliminates the largest source of per-keystroke render cost on wide datasets where ColumnCollectionTable and MetricsTab would otherwise re-render on every setState. 3. Memoise derived arrays (sortedMetrics, datetimeColumns, stringColumns) with one-pair (lastInput, lastOutput) caches so downstream PureComponent / React.memo children stop re-rendering on unrelated state changes. Also hoist three inline itemGenerator={() => ({...})} lambdas to stable class-field arrow functions (newSpatialItem, newMetricItem, newCalculatedColumnItem). 4. IME composition guards in TextAreaControl. Track isComposing state via onCompositionStart / onCompositionEnd, skip handleChange while composing, propagate once on compositionend. Reduces per-IME-word work from N candidate events to one commit. Also converts handleChange to an arrow class field so onChange={this.handleChange} has stable identity across renders (no more .bind(this) in render). Validation semantics are preserved (FR-008): same validators, same error messages, same Save-button gate — only the schedule changes. Existing 34 Jest tests across DatasourceEditor, DatasourceEditorCurrency, and TextAreaControl pass unmodified. Playwright coverage for SC-001, SC-003, and SC-005 deferred to a follow-up commit.

Date: Tue, 28 Apr 2026 09:30:13 -0600 Subject: [PATCH 2/8] fix(datasource-editor): address PR review feedback Three fixes from kgabryje's review on PR #39641: 1. TextAreaControl IME guard double-fire on Firefox/Edge. Per W3C uievents #202, Firefox/Edge fire a synthetic onChange after compositionend with the committed value. Add a one-shot `justComposed` flag, cleared on the next change, so the committed value isn't propagated twice on those browsers. 2. DatasourceEditor onBlur defeated debounce for intra-form navigation. React onBlur bubbles, so tabbing between fields inside the container fired the synchronous flush on every focus change. Guard with `e.relatedTarget` so flushValidation only fires when focus actually leaves the container. 3. Drop `destroyInactiveTabPane`. The lazy-mount benefit isn't worth the UX regression of losing CollectionTable local state (search term, pagination, expanded rows) on every tab switch. The remaining fixes (debounce, memoised derived arrays, stable handler identity, IME guards) carry the perf wins. The .cancel()-vs-.flush() review point requires a deeper refactor of validate() to expose a sync compute path that doesn't depend on the component's setState. Deferred to a follow-up commit. Tests: 51/51 across 6 suites pass.

The naïve .flush() swap doesn't work either: the debounced function calls validate(this.onChange), which writes errors via setState({errors}, callback). React no-ops setState during unmount, so the callback (which calls props.onChange to propagate to the parent) never fires. Fix: split the validate code into a pure computeErrors(): string[] method and a validate(callback) wrapper. Add an optional errorsOverride parameter to onChange. In componentWillUnmount, if the validationPending flag is set, compute errors synchronously and call this.onChange(errors) directly — bypassing the dead-end setState({errors}) entirely. A manual validationPending flag tracks pending state because @types/lodash's DebouncedFunc<> doesn't expose lodash 4.17+'s .pending() method. Scope limit: the drain helps only when the parent outlives the child (route changes, AsyncEsmComponent swaps). When the DatasourceModal itself unmounts simultaneously, the parent's useState setters are also no-ops, so the propagation has nowhere to land. Closing that race fully would require lifting editor state out of React component-local state — out of scope for this PR. Documented in spec/plan/research. Tests: 51/51 across 6 suites pass.

Date: Tue, 28 Apr 2026 13:42:57 -0600 Subject: [PATCH 5/8] test(datasource-editor): cover unmount-drain path (FR-004a) Adds a Jest/RTL test that locks in the contract documented in spec.md FR-004a: when the editor unmounts while a debounced validation is still pending, props.onChange must be called synchronously with the freshly-computed errors. Without the drain (just .cancel(), or naive .flush() that hits the dead-end setState-during-unmount path), the parent never receives the latest typed state. The test uses the "Add item" button on the Calculated columns tab to trigger a synchronous chain that sets validationPending=true (no internal TextControl debounce on this path), then unmounts before the 300ms editor debounce can fire, and asserts props.onChange was called exactly once with the new datasource and an errors array.

Adds two helpers: - createWideTestDataset (helpers/api/dataset.ts) creates a virtual dataset with N integer-aliased columns (default 50). Provides the realistic-size dataset SC-001 calls for without depending on a specific physical table. - createWideTestDatasetForTest (tests/dataset/dataset-test-helpers.ts) wraps it with the testAssets cleanup pattern. Tests need to be verified in CI; local Playwright run blocked by session/SECRET_KEY drift after the alembic re-stamp work earlier this session, unrelated to the test code itself.
