Right. Also, dealing with long-living requests or dribbling data piece
by piece is substantially something different than streaming large
data
to the user agent without holding application resources forever.
I'm not
sure Zope 2 actually differentiates between those two.
It indeed does. The former is implemented as RESPONSE.write, the
latter is implemented as returning something implementing
IStreamIterator to the publisher.
There was some talk a while back about Zope 3 implementing some
form of
"IResult" interface that allowed for streaming. I'm not sure
where that
ended up, though. I seem to remember Jim checking something in.
Yes, there is support for streaming large data without holding
application resources. What you do is write the data to a (temp)
file and
return the file object. The zope.publisher will know what to do. The
"IResult" interface was made private and nowadays just an
implementation
detail.
Right, now I remember. Thanks.
