* gh-106320: Remove _PyInterpreterState_Get() alias (#106321)Victor Stinner2023-07-011-0/+3
| | | | Replace calls to the (removed) slow _PyInterpreterState_Get() with fast inlined _PyInterpreterState_GET() function.
* gh-102541: Fix Helper.help("mod") for non-existent mod (#105934)Kirill Podoprigora2023-07-011-0/+1
| | | | | | If the output arg to Helper() is a stream rather than the default None, which means 'page to stdout', the ImportError from pydoc.resolve is currently not caught in pydoc.doc. The same error is caught when output is None. --------- Co-authored-by: Terry Jan Reedy <tjreedy@udel.edu>
* gh-106316: Remove pytime.h header file (#106317)Victor Stinner2023-07-011-0/+2
| | | | | | | | | | | | | | | | | Remove the "cpython/pytime.h" header file: it only contained private functions. Move functions to the internal pycore_time.h header file. Move tests from _testcapi to _testinternalcapi. Rename also test methods to have the same name than tested C functions. No longer export these functions: * _PyTime_Add() * _PyTime_As100Nanoseconds() * _PyTime_FromMicrosecondsClamp() * _PyTime_FromTimespec() * _PyTime_FromTimeval() * _PyTime_GetPerfCounterWithInfo() * _PyTime_MulDiv()
* gh-106232: Make timeit doc command lines compatible with Windows. (#106296)Terry Jan Reedy2023-07-011-0/+2
| | | | | | Command Prompt (CMD Shell) and older versions of PowerShell require double quotes and single quotes inside the string. This form also works on linux and macOS.

* gh-105775: Convert LOAD_CLOSURE to a pseudo-op (#106059)hms2023-06-291-0/+1
| | | | | | This enables super-instruction formation, removal of checks for uninitialized variables, and frees up an instruction.
* gh-101006: Improve error handling when read marshal data (GH-101007)Serhiy Storchaka2023-06-291-0/+1
| | | | | | | | * EOFError no longer overrides other errors such as MemoryError or OSError at the start of the object. * Raise more relevant error when the NULL object occurs as a code object component. * Minimize an overhead of calling PyErr_Occurred().
* gh-106118: Add O_CLOEXEC preprocessor guard (#106120)Erlend E. Aasland2023-06-281-0/+2

* gh-101634: regrtest reports decoding error as failed test (#106169)Victor Stinner2023-06-281-0/+3
| | | | | When running the Python test suite with -jN option, if a worker stdout cannot be decoded from the locale encoding report a failed testn so the exitcode is non-zero.
* gh-106168: PyTuple_SET_ITEM() now checks the index (#106164)Victor Stinner2023-06-281-0/+5
| | | | | | | | | | | | | PyTuple_SET_ITEM() and PyList_SET_ITEM() now check the index argument with an assertion if Python is built in debug mode or is built with assertions. * list_extend() and _PyList_AppendTakeRef() now set the list size before calling PyList_SET_ITEM(). * PyStructSequence_GetItem() and PyStructSequence_SetItem() now check the index argument: must be lesser than REAL_SIZE(op). * PyStructSequence_GET_ITEM() and PyStructSequence_SET_ITEM() are now aliases to PyStructSequence_GetItem() and PyStructSequence_SetItem().
* gh-104584: Baby steps towards generating and executing traces (#105924)Guido van Rossum2023-06-271-0/+1
| | | | | Added a new, experimental, tracing optimizer and interpreter (a.k.a. "tier 2"). This currently pessimizes, so don't use yet -- this is infrastructure so we can experiment with optimizing passes. To enable it, pass ``-Xuops`` or set ``PYTHONUOPS=1``. To get debug output, set ``PYTHONUOPSDEBUG=N`` where ``N`` is a debug level (0-4, where 0 is no debug output and 4 is excessively verbose). All of this code is likely to change dramatically before the 3.13 feature freeze. But this is a first step.
* Revert "GH-96145: Add AttrDict to JSON module for use with object_hook ↵Łukasz Langa2023-06-261-0/+1

* GH-105793: Add follow_symlinks argument to `pathlib.Path.is_dir()` and ↵Barney Gale2023-06-261-0/+2
| | | | | | | `is_file()` (GH-105794) Brings `pathlib.Path.is_dir()` and `in line with `os.DirEntry.is_dir()`, which will be important for implementing generic path walking and globbing. Likewise `is_file()`.
* gh-105927: Deprecate PyWeakref_GetObject() function (#106006)Victor Stinner2023-06-261-0/+3
| | | Deprecate PyWeakref_GetObject() and PyWeakref_GET_OBJECT() functions.

* gh-106084: Remove old PyObject call aliases (#106085)Victor Stinner2023-06-261-0/+13
| | | | | | | | | | | | | | Remove old aliases which were kept backwards compatibility with Python 3.8: * _PyObject_CallMethodNoArgs() * _PyObject_CallMethodOneArg() * _PyObject_CallOneArg() * _PyObject_FastCallDict() * _PyObject_Vectorcall() * _PyObject_VectorcallMethod() * _PyVectorcall_Function() Update code which used these aliases to use new names.

* GH-89812: Add `pathlib.UnsupportedOperation` (GH-105926)Barney Gale2023-06-221-0/+2
| | | | | | | This new exception type is raised instead of `NotImplementedError` when a path operation is not supported. It can be raised from `Path.readlink()`, `symlink_to()`, `hardlink_to()`, `owner()` and `group()`. In a future version of pathlib, it will be raised by `AbstractPath` for these methods and others, such as `AbstractPath.mkdir()` and `unlink()`.

* gh-105570: Deprecate unusual ways of creating empty TypedDicts (#105780)Alex Waygood2023-06-141-0/+5
| | | Deprecate two methods of creating typing.TypedDict classes with 0 fields using the functional syntax: `TD = TypedDict("TD")` and `TD = TypedDict("TD", None)`. Both will be disallowed in Python 3.15. To create a TypedDict class with 0 fields, either use `class TD(TypedDict): pass` or `TD = TypedDict("TD", {})`.

* gh-105566: Deprecate unusual ways of creating `typing.NamedTuple` classes ↵Alex Waygood2023-06-141-0/+10
| | | | | | | (#105609) Deprecate creating a typing.NamedTuple class using keyword arguments to denote the fields (`NT = NamedTuple("NT", x=int, y=str)`). This will be disallowed in Python 3.15. Use the class-based syntax or the functional syntax instead. Two methods of creating `NamedTuple` classes with 0 fields using the functional syntax are also deprecated, and will be disallowed in Python 3.15: `NT = NamedTuple("NT")` and `NT = NamedTuple("NT", None)`. To create a `NamedTuple` class with 0 fields, either use `class NT(NamedTuple): pass` or `NT = NamedTuple("NT", [])`.
