Prevent the full loading of content of HTTP POST requests into the RAM

[hozblok]

Please, can anyone say how to avoid the following behavior?

For example, we send a large HTTP POST request with multipart/form-data (~2 Gb) using channels, daphne, AsgiHandler and AsgiRequest. (let's say we chose the wrong file to upload).

settings.py contains DATA_UPLOAD_MAX_MEMORY_SIZE = 1024 * 1024 * 25 and FILE_UPLOAD_MAX_MEMORY_SIZE = 1024 * 1024 * 5 settings.

Here in AsgiRequest we raise RequestDataTooBig exception.

So the response is HttpResponse("413 Payload too large", status=413) (here). Ok.

But before all this: here we load two gigabytes of unwanted data into RAM... ?

Perhaps is there a way to check the content-length in the __init__ method of AsgiHandler? How to prevent uploads to RAM correctly?

I think this would be a dupe of #126.

Check out uvicorn, I'm pretty sure it'll handle large requests a lot better.

Yep. This is a duplicate. It'll come but not available yet.
