Comment:
I'm following up on Jeff250's comment.
PEP 3333 says that `wsgi.input` is:
> An input stream (file-like object) from which the HTTP request body
bytes can be read. (The server or gateway may perform reads on-demand as
requested by the application, or it may pre- read the client's request
body and buffer it in-memory or on disk, or use any other technique for
providing such an input stream, according to its preference.)
It adds that:
> The semantics of each method are as documented in the Python Library
Reference
----
In the Python Library Reference, the semantic of [file-like object].read()
is:
> Read at most size bytes from the file (less if the read hits EOF before
obtaining size bytes).
----
This means that:
- WSGI does require a `wsgi.input` file object that blocks on reads until
a buffer of ''exactly'' the requested length is returned, or EOF /
Content-Length is reached,
- the bug is in `modjy`, which does not provide an appropriate file-like
object right now.
