fix(task): guard saveClineMessages against abandoned tasks (fixes #1021) - #1382
Conversation
…-Code-Org#1021) Fire-and-forget saveClineMessages() calls could execute updateTaskHistory() after abandonSubtask's atomicUpdatePair() had already cleared parentTaskId/rootTaskId, silently reattaching the severed parent-child link. Check this.abandoned before updateTaskHistory() to catch both the explicit abort save and any in-flight fire-and-forget saves. Per-task message persistence is unaffected: saveTaskMessages still runs, only the (stale) history-item update is skipped. This is the minimal upstream-main form of the fix developed on the local-usage-stats branch (commit 1d1eb91); that commit's surrounding usage-stats changes are not part of main and are excluded. Regression test in Task.spec.ts: an abandoned task's saveClineMessages() persists messages but never calls updateTaskHistory().

Per CodeRabbit review: document why the provider test double uses the as unknown as MockedClineProvider double assertion (Task receives a full ClineProvider at runtime; this focused unit test only exercises a few methods) — same pattern and rationale as the existing Subtask Rate Limiting block.

Addressed the nitpick in ce34d48: the double assertion in the new test is now documented (Task receives a full ClineProvider at runtime; the focused unit test only exercises these methods — same pattern and rationale as the existing Subtask Rate Limiting block). |

Summary
Fixes #1021 (part of epic #1375).
Fire-and-forget
saveClineMessages()calls could executeupdateTaskHistory()afterabandonSubtask'satomicUpdatePair()had already clearedparentTaskId/'rootTaskId`, silently reattaching the severed parent-child link.Changes
src/core/task/Task.ts—saveClineMessages()now checksthis.abandonedbeforeupdateTaskHistory()and returnsfalsewhen the task was abandoned. This catches both the explicit abort save and any in-flight fire-and-forget saves (the two un-awaitedsaveClineMessages().catch(...)call sites).saveTaskMessages()still runs before the guard; only the (stale) history-item update is skipped, which is exactly the value that would reattach the severed link.Provenance
This is the minimal upstream-main form of the fix developed on the
feature/local-usage-statsbranch (commit1d1eb915e, "fix(task): guard saveClineMessages against abandoned tasks to prevent race in abandonSubtask"). That commit also carried formatting changes for usage-stats code that is not inmain(the dashboard feature ships separately in #1225), so those hunks are deliberately excluded here — the behavioral fix is the guard itself.Test
- Regression test in
- ESLint clean; no suppression count changes.
