[jira] Updated: (MODPYTHON-15) Publisher : iterable return values should be corretly published

["Nicolas Lehuen (JIRA)" <ji...@apache.org>]

Nicolas Lehuen updated MODPYTHON-15:
------------------------------------

    Fix Version: 3.3
                     (was: 3.2)
    Description: 
Suppose this function in a published module :

def index(req)
    req.content_type = 'text/plain'
    yield '1\n'
    yield '2\n'
    yield '3\n'
    yield '4\n'

When published, this module should return a text content with '1\n2\n3\n4\n'.

This could also be useful with a file() object, since they are iterable ; this would provide another way to send a file, only slightly less performing than the send_file() method. Handy when you want to filter a file :

def filter(req,filename):
    f = open(filename,'r')
    for line in f:
        yield re.sub('foo','bar',line)

    Environment: 

It's a little bit more complicated than expected, because it breaks some RPC / JSON code (which rely on str() being called on tuples or lists)... Plus we should implement chunked encoding when returning content produced by iterators, since we can't set the Content-Length header upfront.
