Fix data hooks and adapter edge cases - #3765
Conversation
📝 WalkthroughWalkthroughThe change fixes optional Execa loading, validates local-storage service names, resets stale hook state, handles empty and concurrent mutations, corrects paused polling, and records latency for failed HTTP pings. ChangesReliability fixes
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Pending mutations can still overwrite state after reset, and stale polling callbacks can create overlapping polling loops and extra requests after lifecycle changes. These concrete correctness and resource risks should be fixed or explicitly accepted before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Inline comments:
In `@packages/adapters/src/execa/index.ts`:
- Around line 40-41: Update isExecaModuleWithExeca to access obj.execa directly
after the object and property checks, removing the undocumented type assertion.
In ExecaFunction, replace the any return type with an appropriate type or add
documentation explaining why any is required.
- Around line 6-7: Update the ExecaFunction type alias to use typeof
import('execa').execa instead of a custom callable signature, preserving Execa’s
overloads and child-process return type.
In `@packages/data/src/hooks/useMutation.test.ts`:
- Around line 103-104: Update the resolveFirst and resolveSecond deferred
resolver declarations to accept Response instead of any, and resolve their
promises with actual Response instances rather than partial response-shaped
objects.
In `@packages/data/src/hooks/useMutation.ts`:
- Around line 45-48: Update the reset function in the mutation hook to increment
requestIdRef.current, invalidating any pending mutate calls so their completion
handlers cannot restore data, loading, or mutationCount after reset. Keep the
existing mutate requestId comparison behavior unchanged.
- Around line 16-27: Document the unchecked JSON-to-T assertions in
readMutationResponse by adding an inline explanation at each assertion, or
centralizing both assertions in a helper with that explanation. Keep the
existing empty-response handling and parsing behavior unchanged.
In `@packages/data/src/hooks/usePolling.test.ts`:
- Around line 103-117: Update the added test around TestComponent to remove the
unannotated type assertions: let props.deps infer its array type instead of
using as unknown[], and replace (global as any).hookResult with a typed
test-state holder for hookResult, including the required inline annotation only
if an assertion remains.
- Around line 111-113: Update the dependency-change setup in the test around
hookResult.pause() so it mutates the original deps array element rather than
replacing props.deps; then call rerender() and preserve the existing assertion
flow.
In `@packages/data/src/hooks/usePolling.ts`:
- Around line 99-105: Update the paused branch in usePolling’s useEffect so it
calls setLoading(false) when no request is started after cleanup invalidates a
pending execute call; preserve the existing active branch behavior, and add a
test covering pause() before fn resolves that verifies loading becomes false.
- Around line 99-105: Update the useEffect polling lifecycle around adaptiveRef,
execute, and tick so each effect generation captures its own
AdaptivePollingController and active state. Mark the generation inactive during
cleanup, and require that state before scheduling timeouts or recording adaptive
results, preventing stale callbacks from using the replacement controller or
creating additional polling loops.
In `@packages/data/src/hooks/useSSE.ts`:
- Around line 31-33: Stabilize the parser dependency used by the SSE effect in
useSSE: memoize the parse callback with useCallback or store the latest parser
in a ref, so state-triggered renders do not close and recreate the EventSource.
Preserve updates when url or parser behavior genuinely changes, and add a
regression test covering an inline parser without reconnect churn or clearing
current data.
In `@packages/data/src/http.ts`:
- Line 30: Update the latency-history handling around _latencyHistory.get(url)
to explicitly handle a missing URL entry: create and store a new array, assign
it to history, then push latency through history. Preserve the existing behavior
for URLs that already have a history array and remove the non-null assertion.

component lifecycle test that changes the watched path and verifies the returned
data, error, and loading values; packages/data/src/hooks/useSSE.test.ts lines
104-121 likewise requires a lifecycle-based test that changes parser identity

Karanjot786 TermUI packages/adapters/src/execa/index.ts ExecaFunction
💡 Result:
The file path packages/adapters/src/execa/index.ts is located within the TermUI project, an open-source TypeScript/JavaScript framework for building terminal applications maintained by Karanjot Singh (@Karanjot786) [1][2]. In the context of this repository, the code within packages/adapters/src/execa/index.ts is used to create an abstraction or wrapper around the popular Node.js library execa (which handles process execution) [3][4][5]. The term ExecaFunction refers to a specific type or exported function within that adapter layer, designed to standardize or simplify how child processes are executed or managed across the TermUI framework's various packages [3][4]. As of the latest releases (including v0.1.7), this adapter file has undergone minor maintenance updates [6][4]. It is not a standard part of the upstream execa library, but rather a custom integration within the TermUI ecosystem [1][7][5].

Execa 8 TypeScript types ExecaChildPromise ExecaFunction return type
💡 Result:
In Execa 8, the TypeScript types and return values for asynchronous methods function as follows: The return value of all asynchronous Execa methods (such as execa, execaCommand, etc.) is an object that acts as both a Promise and a Node.js ChildProcess [1][2]. Key TypeScript types in Execa 8: 1. ExecaChildProcess: In versions prior to the breaking changes introduced in version 9, the return type of asynchronous Execa methods is represented by the ExecaChildProcess type [3][4]. This type extends the standard Node.js ChildProcess interface, adds Execa-specific methods (like cancel and an enhanced kill), and acts as a Promise that resolves to the process result [3][4]. 2. ExecaChildPromise: This type represents the Execa-specific promise-like methods added to the subprocess, including catch, kill, and cancel [3][4]. Transitioning to Execa 9: It is important to note that these types were renamed in the major release of Execa 9 [5][6]. If you are migrating or working with newer codebases: - The ExecaChildProcess type was renamed to ResultPromise [7][5]. - The ExecaChildPromise type was renamed to Subprocess [7][5]. Because types in Execa are designed to be automatically inferred, you generally do not need to explicitly type the return value of execa calls [8][9]. Explicit type annotation is primarily necessary only when defining custom functions that handle these objects as parameters or return values [8][9]. For further details on the current API, refer to the official Execa documentation [10][11].

Remove the undocumented assertion and any type.
After the 'execa' in obj check, use typeof obj.execa === 'function'. The as { execa: unknown } assertion is unnecessary. Also replace or document the any return type in ExecaFunction at line 7.

Remove unannotated type assertions from the added test.
The added lines use as unknown[] and (global as any) without inline explanations. As per coding guidelines: **/*.{ts,tsx} forbids any without an inline comment and forbids type assertions without an inline comment. Let deps infer its array type and use a typed test-state holder for hookResult.

createElement copies the outer props object, so props.deps = [2] changes only the caller's object. The hook still receives [1], and the test does not exercise dependency changes.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Clear loading when a paused effect invalidates a request.
If pause() runs while execute() is pending, cleanup increments requestIdRef. The pending request then fails the identity check in Lines 60-64 and cannot clear loading. This paused branch skips both setLoading(true) and execute(). The hook therefore keeps loading === true until resume() starts another request.
Set loading to false in the paused branch, or settle it when cleanup invalidates the request. Add a test that pauses before fn resolves.
Proposed fix
- if (!paused) {
+ if (paused) {
+ setLoading(false);
+ } else {
setLoading(true);
execute();

Guard adaptive polling callbacks by effect generation.
When paused changes, an in-flight old tick can resume after the new effect replaces adaptiveRef.current. It can then schedule a timeout that the old cleanup cannot clear. Repeated pause and resume operations can accumulate polling loops and extra requests. The old request can also record adaptive results on the new controller.
Capture the controller per effect or request, and check an effect-local active flag before scheduling timeouts and recording adaptive results.

Store the latest parser in a ref or require useCallback. An inline parse function changes on each state-triggered render. The [url, parse] effect dependency then closes the current EventSource, resets state, and opens another connection. This can clear the current event and cause reconnect churn. Add a regression test for an inline parser.

Mostly solid (useMutation race guard, 204 handling, localStorage path-traversal block). One blocker: usePolling.ts:139 adds paused to the effect deps, so pause/resume recreates the AdaptivePollingController (line 101), wiping accumulated backoff state each toggle — contradicts the docstring. Gate the initial execute() on pausedRef.current instead of changing deps. |
