1. PEP 333 doesn't indicate that the size parameter for the read() method is
optional. Is it optional or required? If it is optional, is the default value
-1?
2. What are the semantics of environ["wsgi.input"].read(-1) when Content-Length
is provided? Is it guaranteed to return the entire request entity, up to at
most <Content-Length> bytes?
3. What are the semantics of environ["wsgi.input"].read(-1) when the response
has no Content-Length? Can environ["wsgi.input"].read(-1) be used (as the only
available mechanism) to read a chunked response entity?
Putting all this together, are these two programs correct?:
def application(environ, start_response):
start_response("200 OK", [])
yield environ["wsgi.input"].read()
def application(environ, start_response):
start_response("200 OK", [])
yield environ["wsgi.input"].read(-1)
This is another issue where there is a lot of variance between gateways, where
I think a clarification in the specification is needed.
