fix(web): skip close confirmation for idle terminals by nobottomline · Pull Request #9728 · pingdotgg/t3code

nobottomline · 2026-09-04T17:29:39Z

What Changed

Terminal close actions now skip the destructive confirmation when every targeted terminal is known to be idle. Immediately before deciding, the client asks the server for a fresh process-table snapshot; terminals with a running subprocess still prompt, and missing or failed inspection state is treated conservatively and still prompts.

The existing behavior remains unchanged for auto-exit cleanup, bulk closes, and clients without the desktop dialog API.

Why

The confirmation added in #7592 protects running work and terminal history, but it also interrupts closing a fresh terminal or one whose command has already exited. The terminal manager already owns subprocess inspection, so the close flow can preserve the safeguard only when work may actually be interrupted without adding a setting or trusting the one-second background polling cache.

UI Changes

Verified in an isolated desktop profile:

a fresh idle terminal closes immediately from the trash action
a terminal running sleep 120 still shows Close terminal "sleep"?
the same shared close flow covers the terminal drawer, right panel, terminal surface, and Command/Ctrl+W

Idle terminal	After idle close

Running-process safeguard:

Verification

vp test run src/terminal/Manager.test.ts (58 tests)
vp test run src/auth/RpcAuthorization.test.ts (6 tests)
vp test run src/rpc.test.ts src/terminal.test.ts (25 tests)
vp test run src/lib/terminalCloseConfirm.test.ts src/components/ThreadTerminalDrawer.test.ts (11 tests)
vp run typecheck in apps/server, apps/web, packages/contracts, and packages/client-runtime
targeted vp lint on the 12 changed files (no errors; existing React warnings remain outside the changed blocks)
manual desktop pass with an isolated --home-dir: idle close bypassed the dialog; running close retained it

Note

Skip terminal close confirmation for idle terminals via subprocess inspection

Adds the terminalInspectSubprocesses WebSocket RPC, with an input capped at 64 terminal IDs and a per-terminal activity result of true, false, or null (unavailable).
Implements TerminalManager.inspectSubprocesses in Manager.ts under the existing per-thread lock. It deduplicates requested IDs, returns false for missing/non-running sessions, and returns null when a running session cannot be inspected.
Updates terminal close flows in ChatView and ThreadTerminalDrawer to inspect subprocess activity before closing. Known-idle terminals skip the destructive confirmation dialog; running, missing, or unknown activity still prompts.
Authorization requires the orchestration operate scope for the new RPC.
Risk: confirmTerminalClose and confirmInspectedTerminalClose in terminalCloseConfirm.ts now require labeled target objects instead of a label-only array; existing callers must be migrated.

Summary by CodeRabbit

New Features
- Terminal closing now checks current subprocess activity before requesting confirmation.
- Added on-demand inspection across multiple terminals, supporting up to 64 terminal IDs.
- Duplicate terminal IDs are consolidated during inspection.
Bug Fixes
- Close decisions now use fresh subprocess information instead of potentially outdated status.
- Idle terminals can close without an unnecessary confirmation prompt.
- Confirmation remains enabled when activity cannot be determined, helping prevent accidental termination.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR changes the existing terminal-close safety flow and adds a cross-layer subprocess-inspection RPC. Human review is required because it modifies the server auth package and introduces non-opt-in runtime behavior changes across the client and server.

📝 Walkthrough

Walkthrough

Adds a terminal subprocess inspection RPC with bounded schemas and authorization. The web client uses fresh inspection results to skip close prompts for idle terminals and retain prompts for active or unknown terminals.

Changes

Terminal subprocess inspection

Layer / File(s)	Summary
Inspection contracts and RPC command `packages/contracts/src/terminal.ts`, `packages/contracts/src/rpc.ts`, `packages/client-runtime/src/state/terminal.ts`	Defines bounded inspection inputs, nullable activity results, the WebSocket method, and the client runtime command.
Server inspection endpoint `apps/server/src/terminal/Manager.ts`, `apps/server/src/ws.ts`, `apps/server/src/auth/RpcAuthorization.ts`, `apps/server/src/terminal/Manager.test.ts`, `apps/server/src/project/ProjectSetupScriptRunner.test.ts`	Implements deduplicated subprocess inspection, exposes the RPC endpoint, applies terminal authorization, and adds server tests and mock support.
Inspected terminal close confirmation `apps/web/src/lib/terminalCloseConfirm.ts`, `apps/web/src/lib/terminalCloseConfirm.test.ts`, `apps/web/src/components/ChatView.tsx`, `apps/web/src/components/ThreadTerminalDrawer.tsx`	Uses fresh subprocess activity to skip prompts for known idle terminals and prompt for active or unknown activity across terminal close paths.
Lifecycle command serialization validation `packages/client-runtime/src/state/terminal.ts`, `packages/client-runtime/src/state/terminal.test.ts`	Configures inspection with serial lifecycle concurrency and verifies that restart and close wait for an in-flight inspection.
