* bpo-35134: Add Include/cpython/longobject.h (GH-29044)Victor Stinner2021-10-191-0/+1
| | | | | | | | | | Move Include/longobject.h non-limited API to a new Include/cpython/longobject.h header file. Move the following definitions to the internal C API: * _PyLong_DigitValue * _PyLong_FormatAdvancedWriter() * _PyLong_FormatWriter()
* bpo-43760: Add PyThreadState_EnterTracing() (GH-28542)Victor Stinner2021-10-151-6/+61
| | | | | | | | | | Add PyThreadState_EnterTracing() and PyThreadState_LeaveTracing() functions to the limited C API to suspend and resume tracing and profiling. Add an unit test on the PyThreadState C API to _testcapi. Add also internal _PyThreadState_DisableTracing() and _PyThreadState_ResetTracing().
* bpo-45482: Rename namespaceobject.h to pycore_namespace.h (GH-28975)Victor Stinner2021-10-153-2/+4
| | | | | | | | | Rename Include/namespaceobject.h to Include/internal/pycore_namespace.h. The _testmultiphase extension is now built with the Py_BUILD_CORE_MODULE macro defined to access _PyNamespace_Type. object.c: remove unused "pycore_context.h" include.
* bpo-35081: Move interpreteridobject.h to Include/internal/ (GH-28969)Victor Stinner2021-10-151-1/+1
| | | | Move the interpreteridobject.h header file from Include/ to Include/internal/. It only provides private functions.
* bpo-35134: Move classobject.h to Include/cpython/ (GH-28968)Victor Stinner2021-10-151-1/+0
| | | | | | | | | Move classobject.h, context.h, genobject.h and longintrepr.h header files from Include/ to Include/cpython/. Remove redundant "#ifndef Py_LIMITED_API" in context.h. Remove explicit #include "longintrepr.h" in C files. It's not needed, Python.h already includes it.
* bpo-35134: Add Include/cpython/floatobject.h (GH-28957)Victor Stinner2021-10-144-0/+4
| | | | | Split Include/floatobject.h into sub-files: add Include/cpython/floatobject.h and Include/internal/pycore_floatobject.h.
* bpo-45439: Move _PyObject_VectorcallTstate() to pycore_call.h (GH-28893)Victor Stinner2021-10-141-1/+1
| | | | | | | | | | | * Move _PyObject_VectorcallTstate() and _PyObject_FastCallTstate() to pycore_call.h (internal C API). * Convert PyObject_CallOneArg(), PyObject_Vectorcall(), _PyObject_FastCall() and PyVectorcall_Function() static inline functions to regular functions. * Add _PyVectorcall_FunctionInline() static inline function. * PyObject_Vectorcall(), _PyObject_FastCall(), and PyObject_CallOneArg() now call _PyThreadState_GET() rather than PyThreadState_Get().
* bpo-45467: Fix IncrementalDecoder and StreamReader in the ↵Serhiy Storchaka2021-10-142-10/+21
| | | | | | | | | "raw-unicode-escape" codec (GH-28944) They support now splitting escape sequences between input chunks. Add the third parameter "final" in codecs.raw_unicode_escape_decode(). It is True by default to match the former behavior.
* no-issue: Make silence about warning '_POSIX_C_SOURCE redefined' (GH-28948)Dong-hee Na2021-10-141-4/+4
|
* bpo-45461: Fix IncrementalDecoder and StreamReader in the "unicode-escape" ↵Serhiy Storchaka2021-10-142-10/+21
| | | | | | | | | codec (GH-28939) They support now splitting escape sequences between input chunks. Add the third parameter "final" in codecs.unicode_escape_decode(). It is True by default to match the former behavior.
* bpo-45434: pyport.h no longer includes <stdlib.h> (GH-28914)Victor Stinner2021-10-1311-9/+27
| | | | | Include <stdlib.h> explicitly in C files. Python.h includes <wchar.h>.
* bpo-45434: Remove pystrhex.h header file (GH-28923)Victor Stinner2021-10-1310-19/+23
| | | | | | | | | | | | | | | Move Include/pystrhex.h to Include/internal/pycore_strhex.h. The header file only contains private functions. The following C extensions are now built with Py_BUILD_CORE_MODULE macro defined to get access to the internal C API: * _blake2 * _hashopenssl * _md5 * _sha1 * _sha3 * _ssl * binascii
* bpo-45434: Move _Py_BEGIN_SUPPRESS_IPH to pycore_fileutils.h (GH-28922)Victor Stinner2021-10-134-19/+19

* pycore_pystate.h no longer redefines PyThreadState_GET() (GH-28921)Victor Stinner2021-10-1311-44/+56
| | | | | | | | | | | | | | | | | | | | | | Redefining the PyThreadState_GET() macro in pycore_pystate.h is useless since it doesn't affect files not including it. Either use _PyThreadState_GET() directly, or don't use pycore_pystate.h internal C API. For example, the _testcapi extension don't use the internal C API, but use the public PyThreadState_Get() function instead. Replace PyThreadState_Get() with _PyThreadState_GET(). The _PyThreadState_GET() macro is more efficient than PyThreadState_Get() and PyThreadState_GET() function calls which call fail with a fatal Python error. posixmodule.c and _ctypes extension now include <windows.h> before pycore header files (like pycore_call.h). _PyTraceback_Add() now uses _PyErr_Fetch()/_PyErr_Restore() instead of PyErr_Fetch()/PyErr_Restore(). The _decimal and _xxsubinterpreters extensions are now built with the Py_BUILD_CORE_MODULE macro defined to get access to the internal C API.
* bpo-45434: bytearrayobject.h no longer includes <stdarg.h> (GH-28913)Victor Stinner2021-10-131-1/+0
| | | | bytearrayobject.h and _lzmamodule.c don't use va_list and so don't need to include <stdarg.h>.
* bpo-44991: Normalise function and collation callback naming (GH-28209)Erlend Egeberg Aasland2021-10-121-7/+5
|
* bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)Victor Stinner2021-10-1216-14/+24
| | | | | | | * Move _PyObject_CallNoArgs() to pycore_call.h (internal C API). * _ssl, _sqlite and _testcapi extensions now call the public PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs(). * _lsprof extension is now built with Py_BUILD_CORE_MODULE macro defined to get access to internal _PyObject_CallNoArgs().
* bpo-45439: Rename _PyObject_CallNoArg() to _PyObject_CallNoArgs() (GH-28891)Victor Stinner2021-10-1115-35/+35
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().
* bpo-20028: Empty escapechar/quotechar is not allowed for csv.Dialect (GH-28833)Dong-hee Na2021-10-111-9/+4

* bpo-45262, asyncio: Fix cache of the running loop holder (GH-28796)Matthias Reichl2021-10-071-0/+3
| | | Prevent use-after-free of running loop holder via cache.
* bpo-45041: Restore `sqlite3` executescript behaviour for `SELECT` queries ↵Erlend Egeberg Aasland2021-10-071-1/+1
| | | | | | | (GH-28509) * bpo-45041: Restore sqlite3 executescript behaviour for select queries * Add regression test

* bpo-29505: Add fuzzer for ast.literal_eval (GH-28777)Ammar Askar2021-10-062-0/+57
| | | This supercedes https://github.com/python/cpython/pull/3437 and fuzzes the method we recommend for unsafe inputs, `ast.literal_eval`. This should exercise the tokenizer and parser.

* bpo-41710: Add private _PyDeadline_Get() function (GH-28674)Victor Stinner2021-10-017-68/+83
| | | | | | | | Add a private C API for deadlines: add _PyDeadline_Init() and _PyDeadline_Get() functions. * Add _PyTime_Add() and _PyTime_Mul() functions which compute t1+t2 and t1*t2 and clamp the result on overflow. * _PyTime_MulDiv() now uses _PyTime_Add() and _PyTime_Mul().
* bpo-41710: gc_collect_main() uses _PyTime_GetPerfCounter() (GH-28676)Victor Stinner2021-10-011-2/+2
| | | | | | | | | If the DEBUG_STATS debug flag is set, gc_collect_main() now uses _PyTime_GetPerfCounter() instead of _PyTime_GetMonotonicClock() to measure the elapsed time. On Windows, _PyTime_GetMonotonicClock() only has a resolution of 15.6 ms, whereas _PyTime_GetPerfCounter() is closer to a resolution of 100 ns.
* bpo-41710: PyThread_acquire_lock_timed() clamps the timout (GH-28643)Victor Stinner2021-09-303-3/+3
| | | | | | | | | | | | | | | | | | | PyThread_acquire_lock_timed() now clamps the timeout into the [_PyTime_MIN; _PyTime_MAX] range (_PyTime_t type) if it is too large, rather than calling Py_FatalError() which aborts the process. PyThread_acquire_lock_timed() no longer uses MICROSECONDS_TO_TIMESPEC() to compute sem_timedwait() argument, but _PyTime_GetSystemClock() and _PyTime_AsTimespec_truncate(). Fix _thread.TIMEOUT_MAX value on Windows: the maximum timeout is 0x7FFFFFFF milliseconds (around 24.9 days), not 0xFFFFFFFF milliseconds (around 49.7 days). Set PY_TIMEOUT_MAX to 0x7FFFFFFF milliseconds, rather than 0xFFFFFFFF milliseconds. Fix PY_TIMEOUT_MAX overflow test: replace (us >= PY_TIMEOUT_MAX) with (us > PY_TIMEOUT_MAX).
* bpo-41710: Add _PyTime_AsTimespec_clamp() (GH-28629)Victor Stinner2021-09-304-4/+47
| | | | | | | | | | | | | | | Add the _PyTime_AsTimespec_clamp() function: similar to _PyTime_AsTimespec(), but clamp to _PyTime_t min/max and don't raise an exception. PyThread_acquire_lock_timed() now uses _PyTime_AsTimespec_clamp() to remove the Py_UNREACHABLE() code path. * Add _PyTime_AsTime_t() function. * Add PY_TIME_T_MIN and PY_TIME_T_MAX constants. * Replace _PyTime_AsTimeval_noraise() with _PyTime_AsTimeval_clamp(). * Add pytime_divide_round_up() function. * Fix integer overflow in pytime_divide(). * Add pytime_divmod() function.
* bpo-43753: _operator.is_() uses Py_Is() (GH-28641)Victor Stinner2021-09-291-4/+2

* bpo-45211: Remember the stdlib dir during startup. (gh-28586)Eric Snow2021-09-281-0/+10
| | | | | During runtime startup we figure out the stdlib dir but currently throw that information away. This change preserves it and exposes it via PyConfig.stdlib_dir, _Py_GetStdlibDir(), and sys._stdlib_dir. https://bugs.python.org/issue45211
* bpo-35606: Fix math.prod tests using 'start' as keyword parameter (GH-28595)Pablo Galindo Salgado2021-09-281-8/+3

* bpo-45211: Move helpers from getpath.c to internal API. (gh-28550)Eric Snow2021-09-271-56/+8
| | | | | | | | | | | | This accomplishes 2 things: * consolidates some common code between getpath.c and getpathp.c * makes the helpers available to code in other files FWIW, the signature of the join_relfile() function (in fileutils.c) intentionally mirrors that of Windows' PathCchCombineEx(). Note that this change is mostly moving code around. No behavior is meant to change. https://bugs.python.org/issue45211
* bpo-44958: Revert GH-27844 (GH-28574)Erlend Egeberg Aasland2021-09-263-40/+39

* bpo-44019: Implement operator.call(). (GH-27888)Antony Lee2021-09-241-0/+22
| | | | | | Having `operator.call(obj, arg)` mean `type(obj).__call__(obj, arg)` is consistent with the other dunder operators. The semantics with `*args, **kwargs` then follow naturally from the single-arg semantics.
* bpo-21302: time.sleep() uses waitable timer on Windows (GH-28483)Victor Stinner2021-09-221-43/+110
| | | | | | | | | | | | On Windows, time.sleep() now uses a waitable timer which has a resolution of 100 ns (10^-7 sec). Previously, it had a solution of 1 ms (10^-3 sec). * On Windows, time.sleep() now calls PyErr_CheckSignals() before resetting the SIGINT event. * Add _PyTime_As100Nanoseconds() function. * Complete and update time.sleep() documentation.
