This issue is caused by dictresize() and _PyObjectDict_SetItem()
1. a.__dict__.pop('a') convert the dict to combined table which has double keysize.
2. a.a = 1 converts the dict to split table again if there are no instances sharing key with class.
As I wrote before, pop, popitem, and del should not increase key size.
And _PyObjectDict_SetItem shouldn't convert the dict to split-table when the dict doesn't share keys
with the class before calling PyDict_SetItem. |
