* gh-118527: Use `_Py_ID(__main__)` for main module name (#118528)Sam Gross2024-05-031-1/+1
| | | | | Most module names are interned and immortalized, but the main module was not. This partially addresses a scaling bottleneck in the free-threaded when creating closure concurrently in the main module.

* gh-117953: Other Cleanups in the Extensions Machinery (gh-118206)Eric Snow2024-05-033-102/+410
| | | This change will make some later changes simpler.
* gh-116738: Make `_codecs` module thread-safe (#117530)Brett Simmers2024-05-026-79/+120
| | | | | | | | | | | | | | | The module itself is a thin wrapper around calls to functions in `Python/codecs.c`, so that's where the meaningful changes happened: - Move codecs-related state that lives on `PyInterpreterState` to a struct declared in `pycore_codecs.h`. - In free-threaded builds, add a mutex to `codecs_state` to synchronize operations on `search_path`. Because `search_path_mutex` is used as a normal mutex and not a critical section, we must be extremely careful with operations called while holding it. - The codec registry is explicitly initialized as part of `_PyUnicode_InitEncodings` to simplify thread-safety.

* gh-118413: Fix test_release_task_refs on free-threaded build (#118494)Sam Gross2024-05-021-2/+1
| | | | | | The `time.sleep()` call should happen before the GC to give the worker threads time to clean-up their remaining references to objs. Additionally, use `support.gc_collect()` instead of `gc.collect()` just in case the extra GC calls matter.

* GH-118095: Unify the behavior of tier 2 FOR_ITER branch micro-ops (GH-118420)Mark Shannon2024-05-025-21/+56
| | | | | | * Target _FOR_ITER_TIER_TWO at POP_TOP following the matching END_FOR * Modify _GUARD_NOT_EXHAUSTED_RANGE, _GUARD_NOT_EXHAUSTED_LIST and _GUARD_NOT_EXHAUSTED_TUPLE so that they also target the POP_TOP following the matching END_FOR
* gh-82062: Fix support of parameter defaults on methods in extension modules ↵Sergey B Kirpichev2024-05-024-0/+25
| | | | | | | | | (GH-115270) Now inspect.signature() supports references to the module globals in parameter defaults on methods in extension modules. Previously it was only supported in functions. The workaround was to specify the fully qualified name, including the module name.

* docs: typo: tiny grammar change: "pointed by" -> "pointed to by" (#118411)Andrew Zipperer2024-05-025-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * docs: tiny grammar change: "pointed by" -> "pointed to by" This commit uses "file pointed to by" to replace "file pointed by" in - doc for shutil.copytree - docstring for shutil.copytree - docstring _abc.PathBase.open - docstring for pathlib.Path.open - doc for os.copy_file_range - doc for os.splice The docs use "file pointed to by" more frequently than "file pointed by". So, this commit replaces the uses of "file pointed by" in order to make the uses consistent through the docs. ```bash $ grep -ri 'pointed to by' cpython/ ``` yields more results than ```bash $ grep -ri 'pointed by' cpython/ ``` Separately: There are two occurrences of "tree pointed by": - cpython/Doc/library/xml.etree.elementtree.rst for `xml.etree.ElementInclude.include` - cpython/Lib/xml/etree/ElementInclude.py for `include` For those uses of "tree pointed by", I expect "tree pointed to by" instead. However, I found enough uses online of (a) "tree pointed by" rather than (b) "tree pointed to by" to convince me that (a) is in common use. So, this commit does not replace those occurrences of "tree pointed by" to "tree pointed to by". But I will replace them if a reviewer believes it is correct to replace them. * docs: typo: "exists and executable" -> "exists and is executable" --------- Co-authored-by: Andrew-Zipperer <atzipperer@gmail.com>

| | | | | | | | | builds (#118485) Free-threaded builds can intermittently tickle a longstanding bug (24 years!) in the implementation of `threading.Condition`, leading to flakiness in the test suite. Fixing the underlying issue will require more discussion, and will likely apply to most of the concurrency primitives in the `threading` module that are written in Python. See gh-118433 for more details.

| | | | | | | Account for `add_stopiteration_handler` pushing a block for `async with`. To allow generator functions that previously almost hit the `CO_MAXBLOCKS` limit by nesting non-async blocks, the limit is increased by 1. This increase allows one more block in non-generator functions.

| | | | | Adds a test that length-1 tuple-style sequence patterns must end in a comma, since there isn't currently one. Spotted while reviewing Cython's proposed implementation of the pattern matching syntax (https://github.com/cython/cython/pull/4897#discussion_r1489177169) where there was a bug my the reimplementation that wasn't caught against the CPython tests here.
