* closes bpo-35623: Fix integer overflow when sorting large lists (GH-11380)sth2019-01-011-1/+0
| | | | | There is already a `Py_ssize_t i` defined at function scope that is used for similar loops. By removing the local `int i` declaration that `i` is used, which has the appropriate type.
* bpo-33234: Simplify list_preallocate_exact() (GH-11220)Sergey Fedoseev2018-12-291-14/+3

* bpo-35444: Unify and optimize the helper for getting a builtin object. ↵Serhiy Storchaka2018-12-111-3/+5
| | | | | | | | (GH-11047) This speeds up pickling of some iterators. This fixes also error handling in pickling methods when fail to look up builtin "getattr".
* bpo-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-211-0/+1
| | | | Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-1/+1
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-35081: Move accu.h to Include/internal/pycore_accu.h (GH-10271)Victor Stinner2018-11-011-1/+1
| | | | | | | The accu.h header is no longer part of the Python C API: it has been moved to the "internal" headers which are restricted to Python itself. Replace #include "accu.h" with #include "pycore_accu.h".
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-11-011-1/+1
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
* bpo-33234 Improve list() pre-sizing for inputs with known lengths (GH-9846)Pablo Galindo2018-10-281-0/+40
| | | | | | | | | | | | The list() constructor isn't taking full advantage of known input lengths or length hints. This commit makes the constructor pre-size and not over-allocate when the input size is known (the input collection implements __len__). One on the main advantages is that this provides 12% difference in memory savings due to the difference between overallocating and allocating exactly the input size. For efficiency purposes and to avoid a performance regression for small generators and collections, the size of the input object is calculated using __len__ and not __length_hint__, as the later is considerably slower.

* bpo-34301: Add _PyInterpreterState_Get() helper function (GH-8592)Victor Stinner2018-08-031-1/+1
| | | | sys_setcheckinterval() now uses a local variable to parse arguments, before writing into interp->check_interval.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-8/+8
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.

* bpo-32030: Add more options to _PyCoreConfig (#4485)Victor Stinner2017-11-201-8/+3
| | | | | | Py_Main() now handles two more -X options: * -X showrefcount: new _PyCoreConfig.show_ref_count field * -X showalloccount: new _PyCoreConfig.show_alloc_count field

| | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-2/+1
| | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.
