-
Explanation
The PR touches shell child-process and background-execution behavior. The PR description identifies the cancellation race, states that backgrounded and keep-alive survivor rules remain unchanged, and reports no weakened tests or raised timeouts. No blocking risk is identified.
Full details: No Hidden Policy Change
-
Explanation
No hidden policy change found. The PR changes only
src/utils/ShellCommand.tsand its test. The implementation invokes the existing abort handler when an already-aborted signal is observed after listener registration. The handler preserves the existinginterruptsurvivor rule and otherwise uses the existing kill path. No product routing, trust-model, telemetry/network, or permission-policy settings change.

- Line 133: Update the child process setup in the cancellation test to use
process.execPath with a -e JavaScript timer instead of the non-portable sleep
command, while preserving the ignored stdio and existing PID assertion behavior.

Merge readiness
- Rebase: Head is one commit behind live
main(ae83f6e4cf9201ef65ececd09b16c2d0de267879). Rebase before merge. - Draft PR: Still marked draft until you mark it ready for review.
- CI: All required jobs green at head (unit-test shards, smoke-and-tests, dedicated-tests, typecheck, launcher compatibility, pr-intent-scan, CodeQL). No failing required checks.
- Production abort fix: The three-line sync drain in
ShellCommand.tsremains correct at head (no double-invocation on Node/Bun for already-aborted signals; handler safe after constructor init; omitting a secondShell.tspre-spawn check is a deliberate spawn-cost tradeoff, not a lost cancel).
Findings
🟡 P2 — Use a portable long-lived child in the already-aborted regression test
📍 Where: src/utils/ShellCommand.test.ts — already-aborted user-cancel kills a real child promptly (line 133).
💥 What fails: The test spawns sleep, which is not on the standard Windows process PATH. On bare Windows the child errors before exercising cancellation, so the test fails for spawn/PID reasons instead of asserting abort semantics. That contradicts the test’s purpose and OpenClaude’s cross-platform product scope.
const child = spawn('sleep', ['5'], { stdio: 'ignore' })🔎 Root cause: This file’s other cases use mock EventEmitter children; this is the only real spawn. It reuses a POSIX utility on PATH rather than the repo’s established long-lived-child pattern (process.execPath). Production bash may run sleep inside Git Bash, but this test bypasses Shell.exec and hits Node’s executable lookup directly.
📜 Stated contract:
Review tests for meaningful coverage of the changed behavior, isolation of global/env/config state, async cleanup, fake timers, provider profile leaks, and Windows-compatible assumptions.
🏷️ Attribution: PR-introduced. Merge-base had no this test; head adds the non-portable spawn.
📌 In this PR:
src/utils/ShellCommand.test.ts—spawn('sleep', ['5'], …)at line 133
🔒 Unchanged on main: ShellCommand.ts sync abort drain; no change required there for this finding.
🔧 Required correction: Spawn a JavaScript timer via process.execPath and -e, matching sibling tests such as runAgent.output.test.ts, and keep the same timing and abort assertions (elapsedMs < 2_000, isAbort, abortReason, interrupted, signalAborted, status === 'killed').
const child = spawn(
process.execPath,
['-e', 'setInterval(() => {}, 1000)'],
{ stdio: 'ignore' },
)Validation: Run bun test src/utils/ShellCommand.test.ts -t 'already-aborted' on the PR branch (Linux is sufficient for CI; optionally repeat on Windows cmd/PowerShell to confirm the spawn no longer depends on sleep).
🛠️ Author fix: Replace the sleep spawn with the process.execPath -e timer above in this test only; leave assertions unchanged.
🚫 Out of scope: Rewriting other ShellCommand mock tests, changing Shell.ts, or repo-wide Windows CI matrix expansion.

Follow-up on prior review
The prior P2 asked for a portable long-lived child: process.execPath with -e and setInterval, keeping the under-2s and abort assertions. Verified fixed at this head — matches the pattern in runAgent.output.test.ts, replaces sleep, and bun test src/utils/ShellCommand.test.ts passes (6/6, including already-aborted user-cancel kills a real child promptly in ~17ms). Revert of the production sync drain still fails the new test (isAbort: false at tool timeout).
Production change unchanged from the first commit: three-line sync #boundAbortHandler() when abortSignal.aborted at listener attach. Rebase onto ae83f6e4 introduced no additional hunks beyond the portability test commit.

Summary
ShellCommandImpl.#createResultPromisenow runs the abort handler immediately when the signal is already aborted at the moment the'abort'listener is attached.Shell.tschecksabortSignal.abortedbefore spawning, then awaits several setup steps (sandbox wrap, env overrides, output dir/file) beforewrapSpawn. An abort that lands in that window was missed, becauseaddEventListener('abort')never fires for a signal that is already aborted. The command then ran to completion and was reported as an ordinary failure (isAbort: false). This is the intermittentBashTool error output (#1231) > user-cancel abort ...timeout seen on main CI (shard 7,ShellErrorcode 144,abortReason: "user-abort",isAbort: false).Impact
