[issue10701] Error pickling objects with mutating __getstate__

2017-02-20 Thread Raymond Hettinger 

Raymond Hettinger added the comment:

I agree with Antoine that, "As the name suggests, __getstate__ should probably 
not mutate anything."

Unless a problematic non-mutating example can be found, I suggest this be 
closed.  For the most part, our rule has been that pure python code doesn't 
have to (and possibly cannot) defend itself against mid-stream mutation, while 
C code only has to defend itself to the point of avoiding a segfault.  

IMO, "RuntimeError: dictionary changed size during iteration" is an informative 
error message in this case.
