* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-2/+2

* bpo-39481: Implementation for PEP 585 (#18239)Guido van Rossum2020-04-071-0/+2
| | | | | | | | | | | | This implements things like `list[int]`, which returns an object of type `types.GenericAlias`. This object mostly acts as a proxy for `list`, but has attributes `__origin__` and `__args__` that allow recovering the parts (with values `list` and `(int,)`. There is also an approximate notion of type variables; e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`. Type variables are objects of type `typing.TypeVar`.
* bpo-39947: Move Py_EnterRecursiveCall() to internal C API (GH-18972)Victor Stinner2020-03-131-0/+1
| | | | | | Move the static inline function flavor of Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() to the internal C API: they access PyThreadState attributes. The limited C API provides regular functions which hide implementation details.
* bpo-39884: Add method name in "bad call flags" error (GH-18944)Victor Stinner2020-03-121-1/+2
| | | | PyDescr_NewMethod() and PyCFunction_NewEx() now include the method name in the SystemError "bad call flags" error message to ease debug.
* bpo-36144: Update MappingProxyType with PEP 584's operators (#18814)Brandt Bucher2020-03-071-1/+25
| | | We make `|=` raise TypeError, since it would be surprising if `C.__dict__ |= {'x': 0}` silently did nothing, while `C.__dict__.update({'x': 0})` is an error.
* bpo-39573: Finish converting to new Py_IS_TYPE() macro (GH-18601)Andy Lester2020-03-041-2/+2
|
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The bulk of this patch was generated automatically with: for name in \ PyObject_Vectorcall \ Py_TPFLAGS_HAVE_VECTORCALL \ PyObject_VectorcallMethod \ PyVectorcall_Function \ PyObject_CallOneArg \ PyObject_CallMethodNoArgs \ PyObject_CallMethodOneArg \ ; do echo $name git grep -lwz _$name | xargs -0 sed -i "s/\b_$name\b/$name/g" done old=_PyObject_FastCallDict new=PyObject_VectorcallDict git grep -lwz $old | xargs -0 sed -i "s/\b$old\b/$new/g" and then cleaned up: - Revert changes to in docs & news - Revert changes to backcompat defines in headers - Nudge misaligned comments
* bpo-39573: Use Py_TYPE() macro in Objects directory (GH-18392)Victor Stinner2020-02-071-7/+7
| | | Replace direct access to PyObject.ob_type with Py_TYPE().
* bpo-39487: Merge duplicated _Py_IDENTIFIER identifiers in C code (GH-18254)Hai Shi2020-01-301-2/+2
| | | Moving repetitive `_Py_IDENTIFIER` instances to a global location helps identify them more easily in regards to sub-interpreter support.
* bpo-37645: add new function _PyObject_FunctionStr() (GH-14890)Jeroen Demeyer2019-11-051-28/+29
| | | | | | | | | | | | Additional note: the `method_check_args` function in `Objects/descrobject.c` is written in such a way that it applies to all kinds of descriptors. In particular, a future re-implementation of `wrapper_descriptor` could use that code. CC @vstinner @encukou https://bugs.python.org/issue37645 Automerge-Triggered-By: @encukou
* bpo-38644: Pass tstate to Py_EnterRecursiveCall() (GH-16997)Victor Stinner2019-11-041-14/+20
| | | | | | | | | | | | | * Add _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() which require a tstate argument. * Pass tstate to _Py_MakeRecCheck() and _Py_CheckRecursiveCall(). * Convert Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() macros to static inline functions. _PyThreadState_GET() is the most efficient way to get the tstate, and so using it with _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() should be a little bit more efficient than using Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() which use the "slower" PyThreadState_GET().
* bpo-37994: Fix silencing all errors if an attribute lookup fails. (GH-15630)Serhiy Storchaka2019-09-011-19/+15
| | | Only AttributeError should be silenced.
* bpo-37337: Fix a GCC 9 warning in Objects/descrobject.c (GH-14814)Zackery Spytz2019-08-141-1/+1
| | | | Commit b1263d5a60d3f7ab02dd28409fff59b3815a3f67 causes GCC 9.1.0 to give a warning in Objects/descrobject.c.

* bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async ↵Jeroen Demeyer2019-05-311-15/+15
| | | | | | | | | (GH-13464) Automatically replace tp_print -> tp_vectorcall_offset tp_compare -> tp_as_async tp_reserved -> tp_as_async
* bpo-36974: rename _FastCallKeywords -> _Vectorcall (GH-13653)Jeroen Demeyer2019-05-301-4/+4

| | | Adds sys.audit, sys.addaudithook, io.open_code, and associated C APIs.
* bpo-35983: skip trashcan for subclasses (GH-11841)Jeroen Demeyer2019-05-101-2/+2
| | | | | Add new trashcan macros to deal with a double deallocation that could occur when the `tp_dealloc` of a subclass calls the `tp_dealloc` of a base class and that base class uses the trashcan mechanism. Patch by Jeroen Demeyer.
* bpo-36026: make descr error message consistent (GH-11930)Inada Naoki2019-04-011-14/+12
| | | | set.add(0) and set.add.__get__(0) now raise TypeError with same error message.

* 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

* 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 Stinner2018-10-311-1/+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%)

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.
