[issue1615] PyObject_GenericGetAttr suppresses AttributeErrors in descriptors

2014-03-28 Thread Ethan Furman 

Ethan Furman added the comment:

Downside to this patch (stoneleaf.01) is that custom AttributeErrors raised in 
__getattr__ are overridden, which is a pretty severe regression.

[issue1615] PyObject_GenericGetAttr suppresses AttributeErrors in descriptors

2013-10-16 Thread Ethan Furman 

Ethan Furman added the comment:

Well, attached patch doesn't segfault in debug mode, but the errors aren't any 
better; in fact, I'd say their worse. Here's the current output from my test 
script:

===
getter failed for descriptor 'huh'

looking up not_here
looking up huh
huh not in class class '__main__.With'

Traceback (most recent call last):
  File break_getattr.py, line 30, in module
print(TestEnum.one.missing)
AttributeError: getter failed for descriptor 'missing'
===

As you can see, we have even less information when a class level __getattr__ is 
/absent/, and when we do have one, there is no change (which is exactly where 
we really wanted the change). :(

If anyone with more experience wants ownership, feel free to take it from me.  
;)  Otherwise I'll do my best to get this figured out in time for the beta.

2013-09-20 Thread Raymond Hettinger 

Raymond Hettinger added the comment:

Marking this for Python 3.4.  It isn't a bug in the descriptor protocol; 
rather, it is an implementation detail that is sometimes helpful but is mostly 
annoying.
