Nginx request buffering configuration

[etj]

uwsgi reports this warning when booting:

*** WARNING: you have enabled harakiri without post buffering. Slow upload could be rejected on post-unbuffered webservers ***

nginx is usually a buffered webserver, unless otherwise configured.

The configuration indeed states:

geonode-docker/docker/nginx/geonode.conf.envsubst

Line 59 in 68d2f8c

proxy_request_buffering off;

geonode-docker/docker/nginx/geonode.conf.envsubst

Line 115 in 68d2f8c

proxy_request_buffering off;

geonode-docker/docker/nginx/geonode.conf.envsubst

Line 125 in 68d2f8c

uwsgi_request_buffering off;

By removing buffering, django is aware about how many bytes have been transferred, so that it can send some transfer stats to the client real time.
Anyway such buffering may cause uwsgi to terminate connections while uploading.

We need to find out a way to deal with this.

@etj are we using these stats? I don't think we're leveraging on this to show progress, or whatever

@etj I guess that with "such buffering" you mean "such configuration without buffering", right?
