[issue3195] invalid conversion xml.etree.ElementTree.Element object to boolean

[Pavel Strashkin]

New submission from Pavel Strashkin <[EMAIL PROTECTED]>:

Python 2.5.2 (r252:60911, May  7 2008, 15:19:09)
[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from xml.etree.ElementTree import Element
>>> e = Element('Test', {'attr' : 'value'})
>>> b = not e
>>> print b
True

Why i'm getting True here instead of False?
Because of this i can not do:
if not e:
# here some logic
pass

[issue3442] wsgiref.validate.InputWrapper.readline does not accept optional "length" argument

[Pavel Strashkin]

New submission from Pavel Strashkin <[EMAIL PROTECTED]>:

All file/stream-like objects in Python have "readline" method with
optional "length" argument, but wsgiref.validate.InputWrapper doest not
have. Some 3rd party modules/packages use this argument. As result there
is exception:
: readline() takes exactly 1 argument (2 given)

I think wsgiref.validate.InputWrapper.readline must be implemented same
to wsgiref.validate.InputWrapper.read:

def readline(self, *args, **kwargs):
v = self.input.readline(*args, **kwargs)
assert_(type(v) is type(""))
return v

[Pavel Strashkin]

New submission from Pavel Strashkin:

According to http://www.json.org/ and 
https://tools.ietf.org/html/rfc7159#section-7, the solidus ("/") should be 
escaped ("\/") and currently it's not.
