* Remove almost all unpaired backticks in docstrings (#119231)Geoffrey Thomas2024-05-221-11/+11
| | | | | | | | | | | | | | | | | | As reported in #117847 and #115366, an unpaired backtick in a docstring tends to confuse e.g. Sphinx running on subclasses of standard library objects, and the typographic style of using a backtick as an opening quote is no longer in favor. Convert almost all uses of the form The variable `foo' should do xyz to The variable 'foo' should do xyz and also fix up miscellaneous other unpaired backticks (extraneous / missing characters). No functional change is intended here other than in human-readable docstrings.
* gh-117431: Adapt bytes and bytearray .find() and friends to Argument Clinic ↵Erlend E. Aasland2024-04-121-17/+74
| | | | | | | | | | | | | | (#117502) This change gives a significant speedup, as the METH_FASTCALL calling convention is now used. The following bytes and bytearray methods are adapted: - count() - find() - index() - rfind() - rindex() Co-authored-by: Inada Naoki <songofacandy@gmail.com>
* gh-117439: Make refleak checking thread-safe without the GIL (#117469)Sam Gross2024-04-081-1/+1
| | | | | This keeps track of the per-thread total reference count operations in PyThreadState in the free-threaded builds. The count is merged into the interpreter's total when the thread exits.

Leave Modules/_sre/sre.c unchanged, it uses locale dependent functions on purpose. Include explicitly <ctype.h> in _decimal.c to get isascii().

| | | | | | | | | | | PEP-0682 specified that %-formatting would not support the "z" specifier, but it was unintentionally allowed for bytes.

* gh-94673: Ensure Builtin Static Types are Readied Properly (gh-103940)Eric Snow2023-04-271-19/+0
| | | There were cases where we do unnecessary work for builtin static types. This also simplifies some work necessary for a per-interpreter GIL.
* gh-102304: Move the Total Refcount to PyInterpreterState (gh-102545)Eric Snow2023-03-211-1/+1
| | | | | Moving it valuable with a per-interpreter GIL. However, it is also useful without one, since it allows us to identify refleaks within a single interpreter or where references are escaping an interpreter. This becomes more important as we move the obmalloc state to PyInterpreterState. https://github.com/python/cpython/issues/102304
* gh-102304: Consolidate Direct Usage of _Py_RefTotal (gh-102514)Eric Snow2023-03-081-5/+4

* bpo-15999: Accept arbitrary values for boolean parameters. (#15609)Serhiy Storchaka2022-12-031-2/+2
| | | builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.
* gh-99537: Use Py_SETREF() function in C code (#99657)Victor Stinner2022-11-221-3/+1
| | | | | | | | | | | | | | | Fix potential race condition in code patterns: * Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);" * Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);" * Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);" Other changes: * Replace "old = var; var = new; Py_DECREF(var)" with "Py_SETREF(var, new);" * Replace "old = var; var = new; Py_XDECREF(var)" with "Py_XSETREF(var, new);" * And remove the "old" variable.
* gh-99300: Use Py_NewRef() in Objects/ directory (#99332)Victor Stinner2022-11-101-34/+17
| | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in C files of the Objects/ directory.

* gh-89653: Use int type for Unicode kind (#92704)Victor Stinner2022-05-131-1/+1
| | | | Use the same type that PyUnicode_FromKindAndData() kind parameter type (public C API): int.
* Use static inline function Py_EnterRecursiveCall() (#91988)Victor Stinner2022-05-041-1/+1
| | | | | | | | | | | | | | | | Currently, calling Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() may use a function call or a static inline function call, depending if the internal pycore_ceval.h header file is included or not. Use a different name for the static inline function to ensure that the static inline function is always used in Python internals for best performance. Similar approach than PyThreadState_GET() (function call) and _PyThreadState_GET() (static inline function). * Rename _Py_EnterRecursiveCall() to _Py_EnterRecursiveCallTstate() * Rename _Py_LeaveRecursiveCall() to _Py_LeaveRecursiveCallTstate() * pycore_ceval.h: Rename Py_EnterRecursiveCall() to _Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() and _Py_LeaveRecursiveCall()

* bpo-45995: add "z" format specifer to coerce negative 0 to zero (GH-30049)John Belmonte2022-04-111-2/+9
| | | | | | | | Add "z" format specifier to coerce negative 0 to zero. See https://github.com/python/cpython/issues/90153 (originally https://bugs.python.org/issue45995) for discussion. This covers `str.format()` and f-strings. Old-style string interpolation is not supported. Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
* bpo-47070: Add _PyBytes_Repeat() (GH-31999)Pieter Eendebak2022-03-281-17/+29

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
* bpo-46670: Define all macros for stringlib (GH-31176)Victor Stinner2022-02-071-0/+1
| | | | | bytesobject.c, bytearrayobject.c and unicodeobject.c now define all macros used by stringlib, to avoid using undefined macros. Fix "gcc -Wundef" warnings.
* bpo-46417: Add missing types of _PyTypes_InitTypes() (GH-30749)Victor Stinner2022-01-211-1/+1
| | | | | | | | | Add types removed by mistake by the commit adding _PyTypes_FiniTypes(). Move also PyBool_Type at the end, since it depends on PyLong_Type. PyBytes_Type and PyUnicode_Type no longer depend explicitly on PyBaseObject_Type: it's the default of PyType_Ready().
* bpo-45953: Statically allocate and initialize global bytes objects. (gh-30096)Eric Snow2022-01-111-78/+14
| | | | | The empty bytes object (b'') and the 256 one-character bytes objects were allocated at runtime init. Now we statically allocate and initialize them. https://bugs.python.org/issue45953
