* gh-78157: [Enum] nested classes will not be members in 3.13 (GH-92366)Ethan Furman2022-05-065-4/+219
| | | | | | | - add member() and nonmember() functions - add deprecation warning for internal classes in enums not becoming members in 3.13 Co-authored-by: edwardcwang
* gh-90622: Prevent max_tasks_per_child use with a fork mp_context. (#91587)Gregory P. Smith2022-05-064-11/+43
| | | | | Prevent `max_tasks_per_child` use with a "fork" mp_context to avoid deadlocks. Also defaults to "spawn" when no mp_context is supplied for safe convenience.

* Issues/88027: A potential double free in list_sort_impl (#92367)Tim Peters2022-05-061-1/+3

* gh-92356: Fix regression in ctypes function call overhead (#92357)Michael Droettboom2022-05-062-0/+2
| | | | | | 38f331d introduced a delayed initialization routine to set up ctypes formattable (`_ctypes_init_fielddesc`), but inadvertently removed setting the `initialization` flag to 1 to avoid initting each time.
* update argparse's doc of append action. (#92344)Hai Shi2022-05-061-2/+4

* gh-88279: Deprecate PySys_SetArgvEx() (#92363)Victor Stinner2022-05-066-9/+32
| | | | | | | Deprecate the following C functions: * PySys_SetArgv() * PySys_SetArgvEx() * PySys_SetPath()
* gh-57684: Document safe path in What's New in Python 3.11 (#92362)Victor Stinner2022-05-062-0/+12
| | | | Mention also -P and PYTHONSAFEPATH in the Security Considerations page.
* gh-57684: Update tests for PYTHONSAFEPATH=1 (#92358)Victor Stinner2022-05-068-15/+33
| | | | | Fix tests failing with the PYTHONSAFEPATH=1 env var. Enhance also -P help in Python usage (python --help).
* gh-80010: Expand fromisoformat to include most of ISO-8601 (#92177)Paul Ganssle2022-05-066-178/+778
| | | This expands `fromisoformat` to cover most of the common uses of ISO 8601. We may expand the scope more in the future.
* gh-57684: Add -P cmdline option and PYTHONSAFEPATH env var (#31542)Victor Stinner2022-05-0520-35/+174
| | | | | | | | | | | | Add the -P command line option and the PYTHONSAFEPATH environment variable to not prepend a potentially unsafe path to sys.path. * Add sys.flags.safe_path flag. * Add PyConfig.safe_path member. * Programs/_bootstrap_python.c uses config.safe_path=0. * Update subprocess._optim_args_from_interpreter_flags() to handle the -P command line option. * Modules/getpath.py sets safe_path to 1 if a "._pth" file is present.
* gh-82616: Add process_group support to subprocess.Popen (#23930)Gregory P. Smith2022-05-059-28/+73
| | | | | | | | One more thing that can help prevent people from using `preexec_fn`. Also adds conditional skips to two tests exposing ASAN flakiness on the Ubuntu 20.04 Address Sanitizer Github CI system. When that build is run on more modern systems the "problem" does not show up. It seems ASAN implementation related. Co-authored-by: Zackery Spytz <zspytz@gmail.com> Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

* gh-92345: Import rlcompleter before sys.path is extended (#92346)Christian Heimes2022-05-053-3/+15
| | | | | | | | | | ``pymain_run_python()`` now imports ``readline`` and ``rlcompleter`` before sys.path is extended to include the current working directory of an interactive interpreter. Non-interactive interpreters are not affected. Also move imports of ``re`` and ``keyword`` module to top level so they are materialized early, too. The ``keyword`` module is trivial and the ``re`` is already imported via ``inspect`` -> ``linecache``.

* gh-92301: subprocess: Prefer close_range() to procfs-based fd closing (#92303)Alexey Izbyshev2022-05-052-18/+72
| | | | | | | | #92301: subprocess: Prefer `close_range()` to procfs-based fd closing. `close_range()` is much faster for large number of file descriptors, e.g. 4 times faster for 1000 descriptors in a Linux 5.16-based environment. We prefer close_range() only if it's known to be async-signal-safe.

* gh-89022: Improve sqlite3 exceptions related to binding params and API ↵Erlend Egeberg Aasland2022-05-045-20/+28
| | | | | | | | | | | | | misuse (#91572) * Map SQLITE_MISUSE to sqlite3.InterfaceError SQLITE_MISUSE implies misuse of the SQLite C API, which, if it happens, is _not_ a user error; it is an sqlite3 extension module error. * Raise better errors when binding parameters fail. Instead of always raising InterfaceError, guessing what went wrong, raise accurate exceptions with more accurate error messages.
* Use static inline function Py_EnterRecursiveCall() (#91988)Victor Stinner2022-05-0415-521/+524
| | | | | | | | | | | | | | | | 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()
* gh-92036: Fix gc_fini_untrack() (#92037)Victor Stinner2022-05-042-0/+11
| | | | | | | | Fix a crash in subinterpreters related to the garbage collector. When a subinterpreter is deleted, untrack all objects tracked by its GC. To prevent a crash in deallocator functions expecting objects to be tracked by the GC, leak a strong reference to these objects on purpose, so they are never deleted and their deallocator functions are not called.

* gh-78214: marshal: Stabilize FLAG_REF usage (GH-8226)Inada Naoki2022-05-043-10/+17
| | | | | | | | | Use FLAG_REF always for interned strings. Refcounts of interned string is very unstable. When compiling same source, refcounts of interned string in the output may be 1 or >1. It makes FLAG_REF usage unstable. To help reproducible build, use FLAG_REF for interned string even if refcnt(obj)==1.
