* gh-100160: Restore and deprecate implicit creation of an event loop (GH-100410)Serhiy Storchaka2023-01-132-25/+5
| | | | | | | | | | Partially revert changes made in GH-93453. asyncio.DefaultEventLoopPolicy.get_event_loop() now emits a DeprecationWarning and creates and sets a new event loop instead of raising a RuntimeError if there is no current event loop set.

* gh-98724: Fix Py_CLEAR() macro side effects (#99100) (#100070)Victor Stinner2022-12-071-0/+5
| | | | | | | | | | | | | | The Py_CLEAR(), Py_SETREF() and Py_XSETREF() macros now only evaluate their arguments once. If an argument has side effects, these side effects are no longer duplicated. Use temporary variables to avoid duplicating side effects of macro arguments. If available, use _Py_TYPEOF() to avoid type punning. Otherwise, use memcpy() for the assignment to prevent a miscompilation with strict aliasing caused by type punning. Add _Py_TYPEOF() macro: __typeof__() on GCC and clang. Add test_py_clear() and test_py_setref() unit tests to _testcapi.
* gh-93453: No longer create an event loop in get_event_loop() (#98440)Serhiy Storchaka2022-12-061-0/+12
| | | | | | | | | | | | | | | asyncio.get_event_loop() now always return either running event loop or the result of get_event_loop_policy().get_event_loop() call. The latter should now raise an RuntimeError if no current event loop was set instead of creating and setting a new event loop. It affects also a number of asyncio functions and constructors which call get_event_loop() implicitly: ensure_future(), shield(), gather(), etc. DeprecationWarning is no longer emitted if there is no running event loop but the current event loop was set.

* gh-47146: Soft-deprecate structmember.h, expose its contents via Python.h ↵Petr Viktorin2022-11-221-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-99014) The ``structmember.h`` header is deprecated, though it continues to be available and there are no plans to remove it. There are no deprecation warnings. Old code can stay unchanged (unless the extra include and non-namespaced macros bother you greatly). Specifically, no uses in CPython are updated -- that would just be unnecessary churn. The ``structmember.h`` header is deprecated, though it continues to be available and there are no plans to remove it. Its contents are now available just by including ``Python.h``, with a ``Py`` prefix added if it was missing: - `PyMemberDef`, `PyMember_GetOne` and`PyMember_SetOne` - Type macros like `Py_T_INT`, `Py_T_DOUBLE`, etc. (previously ``T_INT``, ``T_DOUBLE``, etc.) - The flags `Py_READONLY` (previously ``READONLY``) and `Py_AUDIT_READ` (previously all uppercase) Several items are not exposed from ``Python.h``: - `T_OBJECT` (use `Py_T_OBJECT_EX`) - `T_NONE` (previously undocumented, and pretty quirky) - The macro ``WRITE_RESTRICTED`` which does nothing. - The macros ``RESTRICTED`` and ``READ_RESTRICTED``, equivalents of `Py_AUDIT_READ`. - In some configurations, ``<stddef.h>`` is not included from ``Python.h``. It should be included manually when using ``offsetof()``. The deprecated header continues to provide its original contents under the original names. Your old code can stay unchanged, unless the extra include and non-namespaced macros bother you greatly. There is discussion on the issue to rename `T_PYSSIZET` to `PY_T_SSIZE` or similar. I chose not to do that -- users will probably copy/paste that with any spelling, and not renaming it makes migration docs simpler.

* gh-99284: [ctypes] remove `_use_broken_old_ctypes_structure_semantics_` ↵Nikita Sobolev2022-11-191-0/+4

* gh-92584: Remove the distutils package (#99061)Victor Stinner2022-11-031-0/+8
| | | | | | | | | | | | Remove the distutils package. It was deprecated in Python 3.10 by PEP 632 "Deprecate distutils module". For projects still using distutils and cannot be updated to something else, the setuptools project can be installed: it still provides distutils. * Remove Lib/distutils/ directory * Remove test_distutils * Remove references to distutils * Skip test_check_c_globals and test_peg_generator since they use distutils
* gh-94172: Remove keyfile, certfile and check_hostname parameters (#94173)Victor Stinner2022-11-031-0/+10
| | | | | | | | | | | | Remove the keyfile, certfile and check_hostname parameters, deprecated since Python 3.6, in modules: ftplib, http.client, imaplib, poplib and smtplib. Use the context parameter (ssl_context in imaplib) instead. Parameters following the removed parameters become keyword-only parameters. ftplib: Remove the FTP_TLS.ssl_version class attribute: use the context parameter instead.
* gh-98401: Invalid escape sequences emits SyntaxWarning (#99011)Victor Stinner2022-11-031-0/+16
| | | | | | | | | | | | | | | | | | | | | | A backslash-character pair that is not a valid escape sequence now generates a SyntaxWarning, instead of DeprecationWarning. For example, re.compile("\d+\.\d+") now emits a SyntaxWarning ("\d" is an invalid escape sequence), use raw strings for regular expression: re.compile(r"\d+\.\d+"). In a future Python version, SyntaxError will eventually be raised, instead of SyntaxWarning. Octal escapes with value larger than 0o377 (ex: "\477"), deprecated in Python 3.11, now produce a SyntaxWarning, instead of DeprecationWarning. In a future Python version they will be eventually a SyntaxError. codecs.escape_decode() and codecs.unicode_escape_decode() are left unchanged: they still emit DeprecationWarning. * The parser only emits SyntaxWarning for Python 3.12 (feature version), and still emits DeprecationWarning on older Python versions. * Fix SyntaxWarning by using raw strings in Tools/c-analyzer/ and wasm_build.py.

* gh-84538: add strict argument to pathlib.PurePath.relative_to (GH-19813)domragusa2022-10-281-0/+5
| | | | | | | | | | | | | | | | | | | | | | | By default, :meth:`pathlib.PurePath.relative_to` doesn't deal with paths that are not a direct prefix of the other, raising an exception in that instance. This change adds a *walk_up* parameter that can be set to allow for using ``..`` to calculate the relative path. example: ``` >>> p = PurePosixPath('/etc/passwd') >>> p.relative_to('/etc') PurePosixPath('passwd') >>> p.relative_to('/usr') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "pathlib.py", line 940, in relative_to raise ValueError(error_message.format(str(self), str(formatted))) ValueError: '/etc/passwd' does not start with '/usr' >>> p.relative_to('/usr', strict=False) PurePosixPath('../etc/passwd') ``` https://bugs.python.org/issue40358 Automerge-Triggered-By: GH:brettcannon
