zope.publisher-3.4.0b1_r76188-py2.4 egg causes server error.

[Darryl Cousins]

My buildout update the zope.publisher egg to
zope.publisher-3.4.0b1_r76188-py2.4 from
zope.publisher-3.4.0a1_1-py2.4.egg. My application is served with paste
and I have pasted the traceback below.

The change between 3.4.0a1 and 3.4.0b1 that causes a server error is in
class HTTPInputStream in file http.py where an additional check for
content size from environment['CONTENT_LENGTH'] has been added. This
returns an empty string rather than None (as returned from
environment['HTTP_CONTENT_LENGTH']. To correct for this the following
works where my addition is to check also for empty string:

    def __init__(self, stream, environment):
        self.stream = stream
        size = environment.get('CONTENT_LENGTH')
        if size is None or size == '': # my change to correct error
            size = environment.get('HTTP_CONTENT_LENGTH')
        if size is None or int(size) < 65536:
            self.cacheStream = StringIO()
        else:
            self.cacheStream = TemporaryFile()

Traceback:

I committed a fix in r77464 and released a zope.publisher 3.4.0b2 egg subsequently to http://download.zope.org/distribution
