Process Entrypoint Drift

entrypoint-process-conflation

In containerized Django setups, treating multiple server roles (migrate, worker, runserver/ASGI) as one entrypoint process causes async/websocket and lifecycle differences to surface as startup delays, restart loops, and broken streaming behaviors.

MATCHESSolution

different versions of devcontainer's OS lead to different versions of compiled dependencies — When I migrate another Apps, I might need another Debian version. Tension: this would lead to the packages land in the sam. Outcome: I figured out later.

MATCHESSolution

I couldn't find any clear solution — from this template. Tension: the issue persists. Outcome: I am deploying backend and frontend separately.

MATCHESSolution

If you convert all operations to perform asynchronously (using `aiosqlite`) , the issue will be mitigated. — When a route in FastAPI is listed as asynchronous (`async def`). Tension: that doesn't fully solve the inherent single writer problem of Sqlite. Outcome: Here's a fully operational update of the FastAPI server logic:.

MATCHESSolution

To manage background processes. Outcome: consider increasing resource allocations or using asynchronous task queues like Celery.

MATCHESSolution

python interpreter just pauses one task and looks at other — In your scenerio where you use asynchronous. Tension: it is not completly usesless. Outcome: Think it like a round-robin.

MATCHESSolution

Try tuning it upwards like: `@serve.deployment(max_ongoing_requests=100) — @serve.deployment(max_ongoing_requests=100) @serve.ingress(app). Outcome: await websocket.accept().

MATCHESSolution

Move the initialization of `qdrant_client` into lifespan. Outcome: override using standard FastAPI mechanism.

MATCHESSolution

You can benefit from the lazy initialization inside the `startup` event. Outcome: async def startup_event(): await SINGLETON.initialize().

MATCHESSolution

any time you have an I/O bound process with lots of idle time — waiting for user input, waiting for a TLS handshake. Tension: wrapping it in an async task can let other code run.

MATCHESSolution

Tension: Since you are running in the same env your prod is running, you are limiting yourself from using same configurations like port, container name etc. Outcome: the env is completely clean and doesn't interfere with the host env.

MATCHESSolution

Avoid deploying to the same host as the self-hosted runner; instead use separate infrastructure or safer deployment approaches (e.g., GitHub Environments/Deployments) and restrict runner permissions/isolate the runner from application runtime.

MATCHESSolution

adding Celery to your project — handling Stripe webhooks. Tension: This would allow for the processing of the webhook event payload to fail once (or more). Outcome: retry the operation.

MATCHESSolution

Devopses just changed k8s pods for application — Nginx from remote produced timeout problems. Tension: nginx stopped closing the connection my app to remote. Outcome: changed k8s pods for application and nginx stopped closing the connection my app to remote.

MATCHESSolution

airflow-server: — docker-compose.yaml file. Outcome: entrypoint: gunicorn --chdir /opt/airflow/py_scripts -b 0.0.0.0:8050 index:server.

MATCHESSolution

use a separate process for your plug-in — The standard way to achieve what you're asking for. Tension: pipes are just too slow. Outcome: communicate using a well-defined protocol.

MATCHESSolution

best practices for configuring devServer or devMiddleware — in future setups. Tension: prevent such vulnerabilities. Outcome: without upgrading the entire Vue CLI or webpack stack.

MATCHESSolution

you can instead run Kestrel on the web and hide it behind another webserver passing requests to it — If you use nginx. Tension: getting it in the right place when ASP.NET wants to do things its way is tricky. Outcome: If you use nginx, you can remove headers from the response easily.

MATCHESSolution

Set up and secure a proxy — in front of your Django application. Tension: Nginx, Tomcat, Apache, etc. Outcome: in front of your Django application.

MATCHESSolution

Stage 2 (startup). Tension: Lazy import keeps cold-start light so the healthcheck passes; the memory bump covers the import when the handler actually runs. Outcome: functions-framework can bind the port.

MATCHESSolution

starting the debugging process by exploring the Expo router file — The error message only points to the entry.js file. Tension: Could this problem be cause d by something in my code, or is it more likely related to something else? Outcome: That was exactly where the bug was.

MATCHESSolution

ctx.setParentLoaderPriority(false);. Tension: now my webapp classpath has priority over Jetty, and I can use logback. Outcome: and now my webapp classpath has priority over Jetty, and I can use logback.

MATCHESSolution

Wrap process.stdout.write at the very start of the entry file — at the very start of the entry file. Tension: This is a sledgehammer — only use when you cannot fix the offending dependency.

MATCHESSolution

Add the frontend origin (http://localhost:8000) to Django settings such as CSRF_TRUSTED_ORIGINS and ensure ALLOWED_HOSTS (and any CORS whitelist) allow the same origin.

MATCHESSolution

Log out of any active Django session for local testing (e.g., Django admin) to stop CSRF enforcement, or properly configure Django CSRF trusted origins to include the frontend origin and ensure CSRF tokens are handled correctly.

MATCHESSolution

Separate the Django web server and Celery worker into different containers or services

MATCHESSolution

check the container logs — When working with Docker and Django it's quite common to get things into a state where the container keeps restarting / won't really start. Tension: This usually indicates a problem in Django and the logs shows us what's wrong with it. Outcome: one will get a more specific error.

MATCHESSolution

instead of passing it as a parameter inside django's container call. Tension: Inside that image there is an executable that I have written using c++.

MATCHESSolution

after an upgrade to Django 4. Tension: it is probably not the best option for efficient production. Outcome: We decided to downgrade Django to v3 until we figure this out.

MATCHESSolution

Configure static and media serving for the production deployment, e.g., use WhiteNoise for static files and ensure media is served (such as adding URL patterns using django.views.static.serve for STATIC_ROOT and MEDIA_ROOT, or correctly configuring Apache/static file handling).

MATCHESSolution

If you start the server and wait several minutes before visiting any pages — does it still take several minutes for that first page? Tension: long startup in general or something request specific. Outcome: Figuring out if it is a long startup in general or something request specific could be a good spot to start.
