* gh-116510: Fix crash during sub-interpreter shutdown (gh-124645)Neil Schemenauer2024-09-272-3/+29
| | | | | Fix a bug that can cause a crash when sub-interpreters use "basic" single-phase extension modules. Shared objects could refer to PyGC_Head nodes that had been freed as part of interpreter shutdown.

* gh-84559: Change the multiprocessing start method default to `forkserver` ↵Gregory P. Smith2024-09-267-33/+75
| | | | | | | | (GH-101556) Change the default multiprocessing start method away from fork to forkserver or spawn on the remaining platforms where it was fork. See the issue for context. This makes the default far more thread safe (other than for people spawning threads at import time... - don't do that!).

* gh-115528: Update language reference for PEP 646 (#121181)Matthew Rahtz2024-09-262-17/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To recap: the objective is to make starred expressions valid in `subscription`, which is used for generics: `Generic[...]`, `list[...]`, etc. What _is_ gramatically valid in such contexts? Seemingly any of the following. (At least, none of the following throw `SyntaxError` in a 3.12.3 REPL.) Generic[x] Generic[*x] Generic[*x, y] Generic[y, *x] Generic[x := 1] Generic[x := 1, y := 2] So introducting flexible_expression: expression | assignment_expression | starred_item end then switching `subscription` to use `flexible_expression` sorts that. But then we need to field `yield` - for which any of the following are apparently valid: yield x yield x, yield x, y yield *x, yield *x, *y Introducing a separate `yield_list` is the simplest way I've been figure out to do this - separating out the special case of `starred_item ,`.

* Programming FAQ: Mention object.__setattr__ as a technique for delegation ↵Jelle Zijlstra2024-09-261-3/+10

* gh-124606: Fix reference leak in error path in `datetime_fromisoformat` in ↵Kirill Podoprigora2024-09-261-0/+2
| | | | | `_datetimemodule.c` (#124607) Previously `tzdata` and `dtstr_clean` were not decrefed in the `invalid_iso_midnight` error path of the `datetime_isoformat` function.
* gh-119127: Fix _functools.Placeholder singleton (#124601)Victor Stinner2024-09-261-13/+35
| | | | | | | * The module state now stores a strong reference to the Placeholder singleton. * Use a regular dealloc function. * Add Py_TPFLAGS_HAVE_GC flag and a traverse function to help the GC to collect the type when a _functools extension is unloaded.
* gh-124498: Fix `TypeAliasType` not to be generic, when `type_params=()` ↵sobolevn2024-09-263-1/+25

* gh-124402: Speed up test_free_threading and test_super (#124491)Victor Stinner2024-09-264-53/+41
| | | | | | | * Reduce the number of iterations and the number of threads so a whole test file takes less than a minute. * Refactor test_racing_iter_extend() to remove two levels of indentation. * test_monitoring() uses a sleep of 100 ms instead of 1 second.
* gh-101100: Make __subclasses__ doctest stable (#124577)Jelle Zijlstra2024-09-261-2/+4
| | | | | Using a standard library class makes this test difficult to maintain as other tests and other parts of the stdlib may create subclasses, which may still be alive when this test runs depending on GC timing.

* gh-123242: Note that type.__annotations__ may not exist (#124557)Jelle Zijlstra2024-09-251-1/+2
| | | | | Closes #123242. The real criterion is that the attribute does not exist on heap types, but I don't think we should discuss heap vs. static types in the language reference.
* gh-119180: Make FORWARDREF format look at __annotations__ first (#124479)Jelle Zijlstra2024-09-252-26/+143

* gh-119180: Avoid going through AST and eval() when possible in annotationlib ↵Jelle Zijlstra2024-09-252-28/+88
| | | | | | | | | | (#124337) Often, ForwardRefs represent a single simple name. In that case, we can avoid going through the overhead of creating AST nodes and code objects and calling eval(): we can simply look up the name directly in the relevant namespaces.
