I am facing perhaps a similar issue when I try to get my web2py (Version
2.5.1-stable+timestamp.2013.06.06.15.39.19) application running on a tablet
with Android 4.3 and sl4a (python 2.6). GETs seems to be okay but POSTs
(e.g. login as user) result in tickets. As any attempt to login results in
tickets and is unsuccessful finally the content of tickets is not displayed
in the browser but I manged to extract the complain:
"(self=FieldStorage(None, None, ''))"

IOError: [Errno 2] No such file or directory
When I add some python code to the cgi module function '
read_lines_to_outerboundary' to inspect self.fp ...
while 1:
print 'DBG: fp -> %s' % str(self.fp)
line = self.fp.readline(1<<16)
if not line:
self.done = -1
break
... I get the following:
DBG: fp -> <open file '<fdopen>', mode 'w+b' at 0x40b41ed0>
Any help or hints how to track down the root cause of this issue are
appreciated very much.
Regards,
Michael
