[Twisted-Python] getPage generates a traceback in abstract.py
I'm really pulling my hair out here. The code in question uses getPage: http://gist.github.com/607124 If I remove the postdata argument to getPage no problem (except the postdata is required by server I'm calling). However, no matter what I put in postdata, I get this: http://gist.github.com/607126 Any help is greatly appreciated. -J

This looks really strange. Could you add a print statement before line 112 of abstract.py, to see what's in self._tempDataBuffer? Ivan
Hi Ivan, This looks really strange. Could you add a print statement before
line 112 of abstract.py, to see what's in self._tempDataBuffer?
The conents of self._tempDataBuffer is indeed a list: ['HTTP/1.1 200 OK\r\n', 'Transfer-Encoding: chunked\r\n', '\r\n', '47\r\n', ['__add__', '__class__', '__contains__', '__delattr__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__getslice__', '__gt__', '__hash__', '__init__', '__le__', '__len__', '__lt__', '__mod__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', '__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '_formatter_field_name_split', '_formatter_parser', 'capitalize', 'center', 'count', 'decode', 'encode', 'endswith', 'expandtabs', 'find', 'format', 'index', 'isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'partition', 'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip', 'split', 'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill'], '\r\n', '0\r\n\r\n'] -J

So it appears as if someone is calling request.write(dir(some string)). If you add a type check to the implementation of write, you'll probably get a traceback pointing at exactly the offending code (and maybe we should add that type check to Twisted). Jean-Paul
Wow I feel stupid. That would be me in the callback that gets fired when getPage completes. Originally I had written this to use web.client.Agent and that code was helping me to inspect the response for debugging. Thank you very much. -J On Sat, Oct 2, 2010 at 11:26 AM, <exarkun@twistedmatrix.com> wrote:
