#2429: paginate() breaks when calling a method with multiple keyword arguments
------------------------+---------------------------------------------------
Reporter: pitrou | Owner: percious
Type: defect | Status: new
Priority: normal | Milestone: 2.1b1
Component: TurboGears | Version: 2.0.3
Severity: normal | Resolution:
Keywords: |

Comment (by pitrou):
Well, `argspec..[:1]` is fine: it removes the `self` from the method
signature, shifting the remaining method parameters to the left:
{{{
>>> def f(self, x, y, z=1):
... pass
...
>>> inspect.getargspec(f)[0][1:]
['x', 'y', 'z']
}}}
However, similar left-shifting must be accomplished on the actual
arguments when mapping them to the parameters from the method signature,
which is what the patch does: when calling `f(*args, **kwargs)`, `args[0]`
has to contain the `self` object for the method, i.e. the controller
instance. Without the patch, `args[0]` can be overwritten with the value
of the first non-self argument (`x` in the example above).
If I look at http://bitbucket.org/turbogears/tg-
dev/src/tip/tg/decorators.py (is it the right repo?), the logic is totally
different in 2.1 so the bug probably only applies to 2.0.
