Hi,
I've rewritten Cython's dict iteration code to use normal PyIter_Next()
iteration on PyPy, but now I get a crash in one of the tests. Apparently,
the iterator fails to raise an exception when the dict is being resized
during iteration. The test goes like this:
'''
def iterdict_change_size(dict d):
"""
>>> count, i = 0, -1
>>> d = {1:2, 10:20}
>>> for i in d:
... d[i+1] = 5
... count += 1
... if count > 5:
... break # safety
Traceback (most recent call last):
RuntimeError: dictionary changed size during iteration
>>> iterdict_change_size({1:2, 10:20})
Traceback (most recent call last):
RuntimeError: dictionary changed size during iteration
>>> print( iterdict_change_size({}) )
DONE
"""
cdef int count = 0
i = -1
for i in d:
d[i+1] = 5
count += 1
if count > 5:
break # safety
return "DONE"
'''
It's supposed to raise an exception when starting the second iteration, but
in PyPy, it crashes at that point instead.
