fix(server): background tasks survive a failed Claude turn on a live process by juliusmarminge · Pull Request #31840 · pingdotgg/t3code

juliusmarminge · 2026-11-06T06:09:02Z

Problem

When a Claude turn ends failed (for example a gateway 502 after its retries are exhausted) while the Claude CLI process stays alive, T3 wiped that thread's background-task roster and wake eligibility. The background Bash and Monitor tasks kept running in that process, but the SDK sends background_tasks_changed only when its list changes, so nothing restored them. On the next turn, t3_background_wait reported the still-running tasks as unmatched, the Waiting roster was empty, and a task's later completion no longer woke the idle thread.

Change

ClaudeAdapterV2 turn finalization still clears background-task state on interrupted turns, and on failed turns whose process is gone or stopping. It keeps the state only when the turn failed, the live query is not stopping, and that query's last turn is this turn. Interrupts still clear because T3 does not declare the SDK's perTaskStopAffordance, so the CLI kills background tasks on interrupt.
RunExecutionService now keeps a failed root run reading provider events while the thread-scoped hasPendingBackgroundWorkForThread probe reports work and no newer run owns the thread. This is the same rule completed runs follow. Without it, a roster change after the failure (the task ending, the process exiting) was never persisted. Unfinished turn items still never hold a failed run open, so a provider that fails without settling its tool items does not pin the subscription. Interrupted runs and runs whose terminal sets childTurnsContinue behave as before.

What a user now sees after such a failed turn, all reflecting work that is still running:

The chat view lists the still-running background tasks.
If the agent had marked a task awaited, the web sidebar shows Waiting rather than the failure badge, and auto-settle waits for it.
The task's completion wakes the thread, as after a completed turn. After a usage-limit failure, that wake may hit the limit again; completed turns already behave that way.
Thread Stop reaches the kept tasks.

Scope and approval

Fixes #31817

The issue also asks to reword the t3_background_wait instructions so models stop re-calling it on every Monitor event and always reply after it. That change affects every Claude thread's prompt and is not part of this PR.

Verification

Focused tests:

ClaudeAdapterV2.test.ts
- "keeps background tasks waitable after a turn fails on a live process" (new, red on main).
- "wakes the idle thread when a task outlives a turn that failed on a live process" (new, red on main).
- "clears background tasks when the Claude process exits mid-turn" (new guard: fails if the guard is reduced to status === "failed").
- "clears the replaced sibling native thread roster when openQuery switches processes": its final assertions pinned the bug (thread B's roster was empty after a failed turn on a live process). They now expect B to keep its task. The test's subject, A's roster being cleared when its process is replaced, is unchanged.
RunExecutionService.test.ts
- "persists a background-task roster clear that arrives after a failed turn" (new, red on main; the completed row is the control).
- "does not pin ingestion on background items when the root turn is failed" (new row of an existing test: guards against failed runs waiting on unsettled turn items).
Full files ClaudeAdapterV2.test.ts, RunExecutionService.test.ts and CodexAdapterV2.test.ts, plus TaskCancelNativeSubagent, TaskCancelUsageLimit, ClaudeAutomaticDelivery, ThreadStop, UsageLimitRecoveryWorker and ClaudeReplayFixtures: 645 passed.

No UI rendering changes, so there are no captures. Not checked: a live Claude CLI behind a gateway that returns 502. The adapter tests drive the SDK frame sequence from the report instead.

…round tasks These tests reproduce #31817. When a Claude turn fails (for example on an API error) while the CLI process stays alive, the adapter wipes the native thread's background-task roster and wake eligibility. The still-running tasks then cannot be awaited, and their completion no longer wakes the idle thread. AI-assisted; verified with the tests and tools listed above.

… on a live process A failed Claude turn cleared the native thread's background-task roster, wake eligibility and opaque replay tombstones even when the CLI process that ran it stayed open and kept the tasks running. The SDK only resends background_tasks_changed on change, so the roster never came back: waits reported the tasks unmatched and their completion never woke the thread. Keep that state when the turn failed and the live, non-stopping query is the one that ran it. Interrupts and failures on a closed or closing process still clear it before root settlement.

…ground tasks Pins the live-process half of the failed-turn guard: without it, a crashed CLI would leave a phantom roster that keeps the session pinned. Co-Authored-By: Claude Opus 5.5 <[email protected]>

…ound work runs A failed turn on a live Claude process now keeps its background tasks, so the run must keep reading provider events until they end, as a completed run does. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Running turn items a failed adapter never settled must not pin the run's subscription; only the provider's own background-work probe keeps it open. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — The change preserves background tasks and their completion events after a failed Claude turn on a live process. An unresolved review concern about consuming roster-clear events could leave delegated children waiting and parent tasks unfinished; that synchronization needs resolution.

Walkthrough

Failed turns now retain background-task state when the Claude query process remains live and owns the turn. Provider-event ingestion continues for an owned thread while its pending-work check reports tasks, and stops when that check reports none.

Changes: Background task lifecycle

Layer / File(s)	Summary
Retain task state for live Claude queries `apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts`, `apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts`	A failed turn retains pending tasks and wake-tracking state if its query process is live and owns the turn. If the process exits, the adapter clears pending tasks. Tests cover task notifications, awaiting tasks, and thread-specific pending status.
Gate event ingestion on pending work `apps/server/src/orchestration-v2/RunExecutionService.ts`, `apps/server/src/orchestration-v2/RunExecutionService.test.ts`	RunExecutionService checks pending work for the latest provider thread. After a failed root turn, ingestion continues while the thread remains owned and the check reports pending work. Tests cover interrupted and failed turns, plus roster updates after completed and failed turns.

Explanation

The description includes all required sections. It explains the problem and change, links issue #31817 and identifies out-of-scope work, and reports focused verification, results, and an untested live-CLI scenario.

Full details: Linked Issues check

Explanation

[#31817] The PR retains the roster after a failed turn when the live query is not stopping and still owns the turn. RunExecutionService also reads later roster updates while thread-scoped background work remains. The PR does not add the issue's requested t3_background_wait guidance to avoid repeated calls and require a brief post-wait reply. ClaudeAdapterV2.ts also clears the roster for every interrupted turn, including a live query; the reviewed code and tests do not establish that all such tasks have stopped.

Resolution

Add and test the requested t3_background_wait guidance. Preserve roster and wake state after interrupted turns when background tasks remain active, or provide and test evidence that interruption always stops those tasks before the roster is cleared.

Keep ingestion open until the roster clear is consumed.

If a failed Claude run belongs to a delegated child and an awaited task clears before ingestion catches up, the persisted roster can keep the child in waiting_for_children. The parent task can remain unfinished without its completion wake. Synchronize the stop check with roster-event delivery.

Claude roster updates never set pendingBackgroundWork, so the live probe could turn false before ingestion consumed the queued roster clear, closing the subscription with the task still persisted. A non-empty stored roster now counts as pending work, for failed and completed turns alike. AI-assisted; verified with the tests and tools listed above.

Evidence

Environment for both sides: real web client/server from separate worktrees; independent fresh databases with automatic seeding disabled; Chromium at 1280×800, light theme; real Claude CLI through a forwarding gateway. Runtime selectors were hidden for privacy. No tests are used as evidence.

Steps: start a 900-second background Bash command and a Monitor emitting progress every 20 seconds; register both IDs and finish the turn. Inject gateway 502 responses until retry exhaustion without pressing Stop. Restore forwarding and request registration of the same IDs again. Let the original tasks finish naturally. Recordings begin with both tasks running.

Failure and re-registration — 4×: roster clears; both original IDs return unmatched.	Failure and re-registration — 4×: roster survives; both original IDs match.
Natural completion: later progress and completion still arrive, although registration was lost.	Natural completion: thread wakes, command finishes, Monitor expires, and roster clears.
Original retry recording	Original retry recording

Actual registration tool outputs, before state transitions, after state transitions, and process survival.

Scripts: seed and reproduction, gateway, state observer, tool-result extractor, and process observer.

AI-assisted; verified with the tests and tools listed above.

Not shown:

The failed-root event-ingestion change was not isolated independently: periodic Monitor notifications and the explicit re-registration request created later turns. Base still received progress and final completion messages, so this evidence does not establish total loss of background wake-up on base.

test(server): a Claude process exiting mid-turn still clears its back…

…ground tasks Pins the live-process half of the failed-turn guard: without it, a crashed CLI would leave a phantom roster that keeps the session pinned. Co-Authored-By: Claude Opus 5.5 <[email protected]>

fix(server): a failed run waits only on the thread's background work

Running turn items a failed adapter never settled must not pin the run's subscription; only the provider's own background-work probe keeps it open. Co-Authored-By: Claude Opus 5.5 <[email protected]>
