* bpo-35444: Unify and optimize the helper for getting a builtin object. ↵Serhiy Storchaka2018-12-111-13/+4
| | | | | | | | (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-33012: Fix more invalid function cast warnings with gcc 8. (GH-10751)Serhiy Storchaka2018-11-271-1/+1
| | | Fix warnings with gcc 8 for wrapperfunc <-> wrapperfunc_kwds casts.
* bpo-33029: Fix signatures of getter and setter functions. (GH-10746)Serhiy Storchaka2018-11-271-7/+7
| | | Fix also return type for few other functions (clear, releasebuffer).
* bpo-35081: Add Include/internal/pycore_tupleobject.h (GH-10705)Victor Stinner2018-11-251-0/+1
| | | | Move _PyTuple_ITEMS() to a new header file: Include/internal/pycore_tupleobject.h
* 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-35199: Add an internal _PyTuple_ITEMS() macro (GH-10434)Victor Stinner2018-11-091-2/+2
| | | | | | | * _PyTuple_ITEMS() gives access to the tuple->ob_item field and cast the first argument to PyTupleObject*. This internal macro is only usable if Py_BUILD_CORE is defined. * Replace &PyTuple_GET_ITEM(ob, 0) with _PyTuple_ITEMS(ob). * Replace PyTuple_GET_ITEM(op, 1) with &_PyTuple_ITEMS(ob)[1].
* 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-30156: Remove property_descr_get() optimization (GH-9541)Victor Stinner2018-10-011-28/+5
| | | | | | | | | | | | | | | | property_descr_get() uses a "cached" tuple to optimize function calls. But this tuple can be discovered in debug mode with sys.getobjects(). Remove the optimization, it's not really worth it and it causes 3 different crashes last years. Microbenchmark: ./python -m perf timeit -v \ -s "from collections import namedtuple; P = namedtuple('P', 'x y'); p = P(1, 2)" \ --duplicate 1024 "p.x" Result: Mean +- std dev: [ref] 32.8 ns +- 0.8 ns -> [patch] 40.4 ns +- 1.3 ns: 1.23x slower (+23%)
* bpo-1617161: Make the hash and equality of methods not depending on the ↵Serhiy Storchaka2018-07-311-18/+15
| | | | | | | | | | | value of self. (GH-7848) * The hash of BuiltinMethodType instances no longer depends on the hash of __self__. It depends now on the hash of id(__self__). * The hash and equality of ModuleType and MethodWrapperType instances no longer depend on the hash and equality of __self__. They depend now on the hash and equality of id(__self__). * MethodWrapperType instances no longer support ordering.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-6/+6
| | | | | | | | | (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.

| | | | | | | * 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).
* bpo-30534: Fixed error messages when pass keyword arguments (#1901)Serhiy Storchaka2017-06-061-1/+1
| | | | | | | to functions implemented in C that don't support this. Also unified error messages for functions that don't take positional or keyword arguments.

* Optimize methoddescr_call(): avoid temporary PyCFunctionVictor Stinner2017-01-181-11/+9
| | | | | | Issue #29259, #29263. methoddescr_call() creates a PyCFunction object, call it and the destroy it. Add a new _PyMethodDef_RawFastCallDict() method to avoid the temporary PyCFunction object.

* Use PyObject_CallFunctionObjArgs()Victor Stinner2016-12-091-1/+1
| | | | | | | | | Issue #28915: Replace PyObject_CallFunction() with PyObject_CallFunctionObjArgs() when the format string was only made of "O" formats, PyObject* arguments. PyObject_CallFunctionObjArgs() avoids the creation of a temporary tuple and doesn't have to parse a format string.
* Use _PyObject_CallMethodIdObjArgs()Victor Stinner2016-12-091-1/+2
| | | | | | | | | Issue #28915: Replace _PyObject_CallMethodId() with _PyObject_CallMethodIdObjArgs() when the format string only use the format 'O' for objects, like "(O)". _PyObject_CallMethodIdObjArgs() avoids the code to parse a format string and avoids the creation of a temporary tuple.
* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-1/+1
| | | | | | 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 Stinner2016-12-011-1/+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.

* Issue #20530: Argument Clinic's signature format has been revised again.Larry Hastings2014-02-081-6/+6
| | | | | | | The new syntax is highly human readable while still preventing false positives. The syntax also extends Python syntax to denote "self" and positional-only parameters, allowing inspect.Signature objects to be totally accurate for all supported builtins in Python 3.4.

"self" parameters are also explicitly marked, allowing inspect.Signature() to authoritatively detect (and skip) said parameters.
