* gh-114271: Make `_thread.ThreadHandle` thread-safe in free-threaded builds ↵mpage2024-03-015-101/+225
| | | | | | | | | | | | | | | | | (GH-115190) Make `_thread.ThreadHandle` thread-safe in free-threaded builds We protect the mutable state of `ThreadHandle` using a `_PyOnceFlag`. Concurrent operations (i.e. `join` or `detach`) on `ThreadHandle` block until it is their turn to execute or an earlier operation succeeds. Once an operation has been applied successfully all future operations complete immediately. The `join()` method is now idempotent. It may be called multiple times but the underlying OS thread will only be joined once. After `join()` succeeds, any future calls to `join()` will succeed immediately. The internal thread handle `detach()` method has been removed.

* gh-84995: Run sys.__interactivehook__() on asyncio REPL startup (#20517)Rémi Lapeyre2024-03-013-39/+62
| | | | | | | | | | This makes the asyncio REPL (`python -m asyncio`) more usable and similar to the regular REPL. This exposes register_readline() as a top-level function in site.py, but it's intentionally undocumented.

* gh-116159: argparse: performance improvement parsing large number of options ↵Amethyst Reese2024-03-011-4/+5
| | | | | | | | | | | | | | (#116162) When parsing positional vs optional arguments, the use of min with a list comprehension inside of a loop results in quadratic time based on the number of optional arguments given. When combined with use of prefix based argument files and a large number of optional flags, this can result in extremely slow parsing behavior. This replaces the min call with a simple loop with a short circuit to break at the next optional argument. Co-authored-by: Zsolt Dollenstein <zsol.zsol@gmail.com>

* gh-116099: Fix refcounting bug in `_queueobj_shared()` (gh-116164)Brett Simmers2024-03-011-3/+1
| | | | | | | | | This code decrefs `qidobj` twice in some paths. Since `qidobj` isn't used after the first `Py_DECREF()`, remove the others, and replace the `Py_DECREF()` with `Py_CLEAR()` to make it clear that the variable is dead. With this fix, `python -mtest test_interpreters -R 3:3 -mtest_queues` no longer fails with `_Py_NegativeRefcount: Assertion failed: object has negative ref count`.

* gh-115398: Expose Expat >=2.6.0 reparse deferral API (CVE-2023-52425) ↵Sebastian Pipping2024-02-2916-21/+435
| | | | | | | | | | | | | | | | | | | | | (GH-115623) Allow controlling Expat >=2.6.0 reparse deferral (CVE-2023-52425) by adding five new methods: - `xml.etree.ElementTree.XMLParser.flush` - `xml.etree.ElementTree.XMLPullParser.flush` - `xml.parsers.expat.xmlparser.GetReparseDeferralEnabled` - `xml.parsers.expat.xmlparser.SetReparseDeferralEnabled` - `xml.sax.expatreader.ExpatParser.flush` Based on the "flush" idea from https://github.com/python/cpython/pull/115138#issuecomment-1932444270 . ### Notes - Please treat as a security fix related to CVE-2023-52425. Includes code suggested-by: Snild Dolkow <snild@sony.com> and by core dev Serhiy Storchaka.

* gh-71052: Fix several Android build issues (#115955)Malcolm Smith2024-02-296-21/+87
| | | | | | | | | | | | | | | | | | | This change is part of the work on PEP-738: Adding Android as a supported platform. * Remove the "1.0" suffix from libpython's filename on Android, which would prevent Gradle from packaging it into an app. * Simplify the build command in the Makefile so that libpython always gets given an SONAME with the `-Wl-h` argument, even if the SONAME is identical to the actual filename. * Disable a number of functions on Android which can be compiled and linked against, but always fail at runtime. As a result, the native _multiprocessing module is no longer built for Android. * gh-115390 (bee7bb331) added some pre-determined results to the configure script for things that can't be autodetected when cross-compiling; this change adds Android to these where appropriate. * Add a couple more pre-determined results for Android, and making them cover iOS as well. This means the --enable-ipv6 configure option will no longer be required on either platform.

* gh-116088: Insert bottom checks after all sym_set_...() calls (#116089)Guido van Rossum2024-02-297-47/+106
| | | | | | | | | This changes the `sym_set_...()` functions to return a `bool` which is `false` when the symbol is `bottom` after the operation. All calls to such functions now check this result and go to `hit_bottom`, a special error label that prints a different message and then reports that it wasn't able to optimize the trace. No executor will be produced in this case.
