Ryan Smith-Roberts added the comment:
I notified secur...@python.org and waited for the go-ahead (from Guido I think)
before opening this bug. If today is the first that the PSRT is hearing about
this, then the issue is broader than just the bugtracker
Ryan Smith-Roberts added the comment:
The send part of the test doesn't matter, since what's being tested happens
before any reads. The MSG multiplier should be removed completely, since none
of the other tests do that.
Patch attached.

I have reviewed this as best I am able. I'll be honest that a lot of clinic.py
makes my eyes cross; I'm used to webdev templating, which is inverted from AC
(flow control inside the template). Not complaining, it's a complicated
subject
Ryan Smith-Roberts added the comment:
No, I'm happy. It isn't really news anyway, since the patch just brings reality
inline with the docs :).

If a custom converter declares both default and converter class attributes, you
get this exception (test file attached):
Exception raised during parsing:
Traceback (most recent call last):
File "Tools/clinic/clinic.py", line 1445
New submission from Ryan Smith-Roberts:
The docs indicate that you can do:
class foo_converter(CConverter):
...
c_default = 'bar()'
py_default = 'Bar'
except that CConverter.__init__() unconditionally overwrites these values.
Patch attached.

Perhaps the test is sending an infeasibly large message. If you remove the

Yes, that makes more sense. The specific syntax is nearly irrelevant compared

I believe the feature you starred resolves this enhancement issue, in which
case my patches are obsolete. And yes, the 'as' syntax makes a lot more sense.
Here's how I hope it works (the arg parsing wrapper remains unchanged):

socketmodule has three builtins which use PyLong_AsUnsignedLong on their

OverflowError. So I vote for #2.

I've realized this is basically insoluble without PEP 457, because any other

When one specifies a default of NULL, the generated signature doc indicates a

A signature of the form

optional argument), b then contains a garbage pointer
