[Zope3-Users] readline() takes exactly 1 argument
Trying to get started on Zope3 but frustrated by a couple of barriers: Barrier 1. Added a folder. Added a ZPT Page (As in Zope3 Developer's Book page 12). Then get system error message: Traceback (most recent call last): Module zope.publisher.publish, line 126, in publish request.processInputs() Module zope.publisher.browser, line 263, in processInputs fs = FieldStorage(fp=fp, environ=self._environ, keep_blank_values=1) Module cgi, line 530, in __init__ self.read_multi(environ, keep_blank_values, strict_parsing) Module cgi, line 650, in read_multi environ, keep_blank_values, strict_parsing) Module cgi, line 532, in __init__ self.read_single() Module cgi, line 665, in read_single self.read_lines() Module cgi, line 687, in read_lines self.read_lines_to_outerboundary() Module cgi, line 715, in read_lines_to_outerboundary line = self.fp.readline(116) TypeError: readline() takes exactly 1 argument (2 given) I did a search of archives and found references to a patch of http.py and tales of success in solving the same problem: Yes.
