[Pyobjc-dev] PyObjCRT_AlignOfType: Unhandled type '3f' ?

[Nicolas R. <Nic...@lr...>]

Hi,

Playing with CFRunLoops in python, I came across the following problem:

	from CoreFoundation import *
	s = CFSocketCreateWithNative(kCFAllocatorDefault, 0, 0, 0, 0)

	Traceback (most recent call last):
	  File "/Users/roussel/Desktop/a.py", line 5, in <module>
	    s = CFSocketCreateWithNative(kCFAllocatorDefault, 0, 0, 0, 0)
	internal_error: PyObjCRT_AlignOfType: Unhandled type '3f' ?

Note that this problem also happens when passing a callback as 4th  
argument and/or a CFSocketContext  as 5th argument.

All the arguments in the example above seem valid from a PyObjC point  
of view, as far as I can tell from  
CFSocketCreateWithNative.__metadata__(). I don't understand, however,  
why there's a reference to CFXMLParserContext:

{

   'retval': {'null_accepted': True, 'already_retained': True, 'type':  
'^{__CFSocket=}', 'already_cfretained': False},

   'arguments': (
       {'null_accepted': True, 'already_retained': False, 'type':  
'^{__CFAllocator=}', 'already_cfretained': False},
       {'already_retained': False, 'type': 'i', 'already_cfretained':  
False},
       {'already_retained': False, 'type': 'L', 'already_cfretained':  
False},
       {'null_accepted': True, 'already_cfretained': False,  
'callable': {'retval': {'already_retained': False, 'type': 'v',  
'already_cfretained': False}, 'arguments': ({'null_accepted': True,  
'already_retained': False, 'type': '^{__CFSocket=}',  
'already_cfretained': False}, {'already_retained': False, 'type': 'L',  
'already_cfretained': False}, {'null_accepted': True,  
'already_retained': False, 'type': '^{__CFData=}',  
'already_cfretained': False}, {'null_accepted': True,  
'already_retained': False, 'type': '^v', 'already_cfretained': False},  
{'null_accepted': True, 'already_retained': False, 'type': '^v',  
'already_cfretained': False}), 'variadic': False}, 'already_retained':  
False, 'type': 'n^?', 'callable_retained': True},
       {'null_accepted': True, 'already_retained': False, 'type':  
'n^{_CFXMLParserContext=i^v^?^?^?}', 'already_cfretained': False}
   ),

   'variadic': False

}

The code in objc_support.m didn't help me understand all this...

Can someone explain how I can fix this and use CFSocketCreateWithNative?

Nicolas
