Comment (by Florian Apolloner):
> the HTTP server must send either `Content-Length` or `Transfer-Encoding:
chunked`
I do not think this is true, a third option is most likely to simply close
the connection.
> It’s less clear that the WSGI application should be responsible for
sending it explicitly.
It is explicitly clear that the WSGI application is not required to send
this in PEP 3333 (https://peps.python.org/pep-3333/#handling-the-content-
length-header):
> If the application does not supply a Content-Length header, a server or
gateway may choose one of several approaches to handling it. The simplest
of these is to close the client connection when the response is completed.
So I would argue that this is a bug in uWSGI. This is also not the first
WSGI incompatibility in uWGSI, for instance I fixed a rather annoying
issue with close:
https://github.com/unbit/uwsgi/commit/1746254fec076bd52e7682187041e82fafad5427
> This is easy to reproduce without Django, so I don’t think we should
feel obligated to avoid fixing this just to have a reproduction recipe.
The thing is, if we fix this in Django just to workaround about a spec
incompatibility in uWSGI (imo), then the next framework has to do the same
and we just might hide a harder to fix bug. Fixing this in uWSGI would
properly fix this for all frameworks.
