Serhiy Storchaka added the comment:

Added checks for errors in C code (they are needed even without supporting 
Python longs, PyInt_AsLong() can fail with Python ints) and a fast path for 
Python longs in PyInt_AsLong() (avoid creating temporary Python int).

[issue28998] Unifying Long Integers and Integers in 2.7

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Since implementing PEP 237 (Unifying Long Integers and Integers) in Python 2.4 
int and long instances became interchangeable. Virtually any function that 
needs an integer, accepts both int and long. But there are few places where 
only int is accepted. Since it is easy unintentionally convert int to long (add 
and subtract large int, or add 0L), this can lead to subtle errors in rare 
circumstances.

Proposed patch makes few places that accepted only int accepting long too. This 
mainly is changing isinstance(x, int) to isinstance(x, (int, long)).
