a9406e77fa Issue #25421: __sizeof__ methods of builtin types now use dynamic basic size. 
This allows sys.getsize() to work correctly with their subclasses with
__slots__ defined.

necessary at all.

ac2ef65c32 Make the unicode equality test an external function rather than in-lining it. 
The real benefit of the unicode specialized function comes from
bypassing the overhead of PyObject_RichCompareBool() and not
from being in-lined (especially since there was almost no shared
data between the caller and callee).  Also, the in-lining was
having a negative effect on code generation for the callee.

4897300276 Minor factoring: move redundant resize scaling logic into the resize function. 2015-07-03 20:00:03 -07:00

3c1f52e829 Call set_lookkey() directly to avoid unnecessary memory spills and reloads. 2015-07-03 18:31:09 -07:00

15f0869609 Move insertion resize logic into set_insert_key(). 
Simplifies the code a little bit and does the resize check
only when a new key is added (giving a small speed up in
the case where the key already exists).

Fixes possible bug in set_merge() where the set_insert_key()
call relies on a big resize at the start to make enough room
for the keys but is vulnerable to a comparision callback that
could cause the table to shrink in the middle of the merge.

Also, changed the resize threshold from two-thirds of the
mask+1 to just two-thirds.  The plus one offset gave no
real benefit (afterall, the two-thirds mark is just a
heuristic and isn't a precise cut-off).

7e3592dca6 Harmonize the bottom of the outer loop with its entry point 
giving a small simplification.  Timings show that hash
pre-check seems only benefit the inner-loop (the linear probes).
