bpo-32422: Reduce lru_cache memory usage (GH-5008) 2017-12-26 02:03:24 +09:00
Serhiy Storchaka 4ab46d7949 bpo-31497: Add private helper _PyType_Name(). (#3630)

Eric Snow 2ebc5ce42a bpo-30860: Consolidate stateful runtime globals. (#3397) 
* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

Victor Stinner 0f7b0b397e bpo-29735: Optimize partial_call(): avoid tuple (#516) 
* Add _PyObject_HasFastCall()
* partial_call() now avoids temporary tuple to pass positional
  arguments if the callable supports the FASTCALL calling convention
  for positional arguments.
* Fix also a performance regression in partial_call() if the callable
  doesn't support FASTCALL.
