Graph/orphaned-async-after-destroy

Pattern

Async Lifecycle Cancellation

orphaned-async-after-destroy

Tasks started with raw Task.Delay keep running after a Component or GameObject is destroyed, causing lingering work and inconsistent frame/beat behavior; lifecycle-aware cancellation via the Component’s built-in task mechanism avoids orphaned async execution.

A component suspended while responding to synchronous input

the background job never runs — my `BackgroundTasks` only execute when declared inside an async dependency. Tension: No exception is raised, the route returns normally. Outcome: If I move the `bg.add_task()` call into the route itself, it works as expected.

Everything works well like intent EXCEPT lifespan does not work (print to console) anymore.

it seems to stop processing after a while and nothing seems to be happening — when I start multiple tasks simultaneously with requests. Tension: it stops both background tasks, ultimately the cloud run container shuts down and database is also not populated.

Waiting for background tasks to complete. — Whenever I gracefully shut down my FastAPI app by saving a file (with the `--reload` option). Tension: "Shutting down sessions" is never logged because it is waiting for all background tasks to be completed, which will never happen. Outcome: How am I supposed to close my sessions so that FastAPI can properly shut down?

it will execute only once because added it in lifespan — I have added scheduler code in lifespan. Tension: my scheduler condition is: Run the task everyday at 6 am, with `start_time` being 6 am and `end_time` 8 am. Outcome: how can I execute job everyday.

the workflow hangs on the "Post Run actions/checkout@v3" step until it eventually times out — deploying an Angular app to Azure Static Web Apps using GitHub Actions. Tension: the build process completes without errors, but the workflow hangs. Outcome: Azure couldn't do; hence it got hang & the process ran indefinitely.

When a GitHub Actions workflow is cancelled, the runner terminates the Docker container for the containerized step, preventing in-container teardown logic from running. The user wants to intercept the container termination to execute cleanup commands.

GitHub Actions workflow runs can’t be easily distinguished in the runs list when the actual work is or isn’t needed, since executions look similar and only differ slightly in runtime. The user wants the workflow to clearly show “skipped” when no action is required.

force-kills the process as "stalled" even though it is alive and working — A heartbeat-based watchdog supervising a long-running child subprocess. Outcome: the run is killed.

An async function was passed to useActionState, but it was dispatched outside of an action context. — after submitting. Tension: Either pass the dispatch function to an `action` prop, or dispatch manually inside `startTransition`.

I don't see how I can call it with argument like : — useActionState(removeTask, { message: "",. Tension: calling remove task directly works fine. Outcome: onClick={async () => await handleRemoveTask(task.id)}.

Resetting the timer by lifting/resetting state in the parent causes the app/game to become unresponsive due to frequent re-renders. The Timer component also attempts to reset its local state during render, leading to problematic behavior.

when the activity is destroyed, the media playback pauses, but the service appears to remain active—its notification stays visible, and the user can still resume playback. Outcome: I’m not sure how to properly stop the service when needed.

I can't store all of my tasks inside a BlockingQueue first because it would be too many tasks to handle in-memory

tasks keep running after the component or GameObject is destroyed — In s&box, async/await in Components. Tension: Using raw Task.Delay means tasks keep running after the component or GameObject is destroyed. Outcome: causing null reference exceptions and ghost behavior.

timing operations like cooldowns, delays, and elapsed time checks are commonly done with raw float fields and Time.Now comparisons — In s&box. Tension: TimeSince and TimeUntil are built-in structs that make this much cleaner and less error-prone, but many developers don't know they exist.

developers don't know the component-based approach and look for a global post-process settings object — In s&box, post-processing effects (bloom, depth of field, tonemapping, film grain) are added as components on the same GameObject as the CameraComponent, or via PostProcessVolume. Tension: developers don't know the component-based approach. Outcome: or via PostProcessVolume for zone-based blending.

Tension: The change is not propagated to clients. Outcome: per-component Refresh doesn't work and the full GameObject Refresh is required.

Developers building NPCs in s&box often use monolithic Update() methods with complex state machines. — in s&box. Tension: This becomes hard to extend and debug. Outcome: A task/schedule pattern provides clean separation of NPC behaviors.

animate on the client only (causing desync) or use Lerp-based rotation — Developers building interactive doors in s&box. Tension: doesn't support custom easing. Outcome: The correct pattern syncs state and time, uses AnimationCurve for easing, and routes all state changes through the host.

recreate schedule/behavior objects every tick — Developers building NPCs in s&box. Tension: causing allocations. Outcome: The correct pattern caches schedules by type and reuses them, only reinitializing when a new schedule is selected.

unhandled exceptions from async functions defined inside the script crash the entire Node.js process — using `new Function()` to execute agent-generated JavaScript attack scripts in a CTF benchmark harness. Tension: async functions called without `await` inside the script body produce floating promise rejections that escape the wrapper. Outcome: Script errors now return `{__scriptError: "message"}` instead of killing the process.

`[dream:prune] 0 orphans deleted` fired on every pipeline run — Graph cleanup queries that compare a node's `createdAt` property against `datetime() - duration('PT48H')`. Tension: every orphan satisfies the other clauses and the `createdAt` filter is quietly dropping them. Outcome: Orphaned nodes accumulate indefinitely.

the custom requestAnimationFrame loop never went idle — after live graph traversal events. Tension: those unresolved pulses stayed in the pulse map. Outcome: The renderer also performed full instanced-node matrix updates during pulse-only frames and kept expensive force-graph link rendering active longer than necessary.

Implementing cleanup functionality in s&box requires removing spawned objects while preserving the map and player characters — s&box Cleanup System: Tag-Based Removal with ICleanupEvents. Tension: Filtering objects by tags (removable vs map entities). Outcome: Handling ownership for multiplayer cleanup.

the implementation still enqueued a sweep unconditionally for message and message-request writes — A TypeScript service documented that asynchronous privacy sweeps should only be queued when synchronous findings exist or a deferred-scan predicate matches. Tension: the implementation still enqueued a sweep unconditionally. Outcome: for message and message-request writes.

aborted assistant turns with empty text but an errorMessage were invisible in the chat projection — in the chat projection. Tension: leaving the UI polling after tool completion with no visible response.
