fix(task): reset isStreaming in abortTask to prevent UI lock after task switch (fixes #257) by proyectoauraorg · Pull Request #388 · Zoo-Code-Org/Zoo-Code

proyectoauraorg · 2026-05-29T01:35:58Z

Fixes #257. Resets isStreaming and isWaitingForFirstChunk in abortTask() so the UI unlocks immediately when a task is aborted or abandoned during task switch. All delegation tests pass (14/14).

Summary by CodeRabbit

Bug Fixes
- Fixed an issue where aborting a task could leave the interface in a locked state due to uncleared streaming indicators.

…provider Merging 12 new test cases covering completePrompt, streaming resilience, and edge cases.

Dependabot bump. Compatible: project requires node>=20.20.2, uuid v14 requires node>=20.

# Conflicts: # pnpm-lock.yaml

…ter task switch When a task switch occurs via abortTask() (e.g., removeClineFromStack, clearTask), the isStreaming flag was not being reset. This left the chat input locked in 'API Request...' state because ClineProvider checks getCurrentTask()!.isStreaming to determine if the UI should be enabled. Added isStreaming=false and isWaitingForFirstChunk=false reset in abortTask() alongside the existing abort=true flag, ensuring the UI unlocks immediately when a task is aborted or abandoned. Fixes Zoo-Code-Org#257

📝 Walkthrough

Walkthrough

This PR fixes a UI lockup issue where chat remains stuck in "API Request..." state after switching tasks or contexts. The abortTask() function now resets streaming-related UI flags (isStreaming and isWaitingForFirstChunk) immediately when abort is triggered, allowing the chat input to re-enable and accept new messages.

Changes

Task Abort Streaming State Reset

Layer / File(s)	Summary
Reset streaming UI state on task abort `src/core/task/Task.ts`	`abortTask()` now resets `isStreaming` and `isWaitingForFirstChunk` flags immediately after setting `abort = true`, preventing UI lockup when task switches occur without full session delegation/resume flow.

Poem

🐰 A task switch no longer leaves the chat in chains,
Streaming flags reset, freedom regains!
No more "API Request" locks the poor soul,
Abort now completes, and messages roll. ✨

Check name	Status	Explanation	Resolution
Description check	⚠️ Warning	The PR description is missing the required template structure, including a formal 'Related GitHub Issue' section, detailed 'Description' of implementation, and 'Test Procedure' with verification steps.	Expand the description to follow the repository template: add a formal 'Closes: `#257`' section, detail the implementation approach in 'Description', and document test procedures for reviewers.
Out of Scope Changes check	⚠️ Warning	The PR includes out-of-scope changes: a uuid dependency version bump (uuid ^11.1.0) and removal of a Mimo provider test unrelated to the `#257` streaming state issue, introduced from a shared base.	Separate out-of-scope changes into dedicated commits or PRs: move uuid version pin and Mimo test removal to a separate maintenance PR focused on those specific issues.

Did you mean to commit this?

An accidental uuid 11.1.0→14.0.0 bump leaked into this branch and broke the Windows unit tests: uuid@14 drops the Math.random fallback and now requires globalThis.crypto.getRandomValues, which the Vitest forks pool on Windows (Node 20) does not provide. Reverting to ^11.1.0 matches upstream/main and restores green CI. Also removes tmp/README.md, an editor scratch file that was committed by mistake.

proyectoauraorg · 2026-05-29T19:43:48Z

Good catch — that tmp/README.md was an accidental local scratch file and has now been removed (816121f).

I also reverted an unintended uuid 11→14 bump that was causing the Windows unit-test failures on this branch, so CI should be back to normal. Thanks for flagging it.
