* gh-119577: Adjust DeprecationWarning when testing element truth values in ↵Jacob Walls2024-06-077-13/+21
| | | | | ElementTree (GH-119762) Adjust DeprecationWarning when testing element truth values in ElementTree, we're planning to go with the more natural True return rather than a disruptive harder to code around exception raise, and are deferring the behavior change for a few more releases.
* GH-119054: Add "Reading directories" section to pathlib docs (#119956)Barney Gale2024-06-061-95/+102
| | | | | | Add a dedicated subsection for `Path.iterdir()`-related methods, specifically `iterdir()`, `glob()`, `rglob()` and `walk()`. Co-authored-by: Jelle Zijlstra <jelle.zijlstra@gmail.com>
* gh-120178: Documentation typo corrections (#120179)David Lowry-Duda2024-06-063-3/+3

* gh-117657: Fix TSAN race involving import lock (#118523)Sam Gross2024-06-067-105/+90
| | | | | This adds a `_PyRecursiveMutex` type based on `PyMutex` and uses that for the import lock. This fixes some data races in the free-threaded build and generally simplifies the import lock code.

* Restore decimal context after decimal doctests (GH-120149)Serhiy Storchaka2024-06-061-3/+7

* gh-120128: fix description of argument to ipaddress.collapse_addresses() ↵Jan Kaliszewski2024-06-052-2/+2
| | | | | | (#120131) The argument to collapse_addresses() is now described as an *iterable* (rather than *iterator*).
* pathlib ABCs: remove duplicate `realpath()` implementation. (#119178)Barney Gale2024-06-052-70/+57
| | | | | | | | | Add private `posixpath._realpath()` function, which is a generic version of `realpath()` that can be parameterised with string tokens (`sep`, `curdir`, `pardir`) and query functions (`getcwd`, `lstat`, `readlink`). Also add support for limiting the number of symlink traversals. In the private `pathlib._abc.PathBase` class, call `posixpath._realpath()` and remove our re-implementation of the same algorithm. No change to any public APIs, either in `posixpath` or `pathlib`. Co-authored-by: Nice Zombies <nineteendo19d0@gmail.com>
* gh-115225: Raise error on unsupported ISO 8601 time strings (#119339)benchatt2024-06-054-0/+7
| | | | | | | | Some time strings that contain fractional hours or minutes are permitted by ISO 8601, but such strings are very unlikely to be intentional. The current parser does not parse such strings correctly or raise an error. This change raises a ValueError when hours or minutes contain a decimal mark.

* gh-120065: Increase `collect_in_thread` period to 5 ms. (#120068)Sam Gross2024-06-051-1/+1
| | | | | This matches the default GIL switch interval. It greatly speeds up the free-threaded build: previously, it spent nearly all its time in `gc.collect()`.

* gh-119999: Fix potential race condition in `_Py_ExplicitMergeRefcount` (#120000)Sam Gross2024-06-041-8/+11
| | | | | | We need to write to `ob_ref_local` and `ob_tid` before `ob_ref_shared`. Once we mark `ob_ref_shared` as merged, some other thread may free the object because the caller also passes in `-1` as `extra` to give up its only reference.

* gh-120048: Make `test_imaplib` faster (#120050)Sam Gross2024-06-041-14/+8
| | | | | | | | | | | The `test_imaplib` was taking 40+ minutes in the refleak build bots because the tests waiting on a client `self._setup()` was creating a client that prevented progress until its connection timed out, which scaled with the global timeout. We should set `connect=False` for the tests that don't want `_setup()` to create a client. Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

* gh-120039: Reduce expected timeout in test_siginterrupt_off (#120047)Sam Gross2024-06-041-3/+3
| | | | | The process is expected to time out. In the refleak builds, `support.SHORT_TIMEOUT` is often five minutes and we run the tests six times, so test_signal was taking >30 minutes.

* gh-117657: Fix race involving GC and heap initialization (#119923)Sam Gross2024-06-044-3/+7
| | | | | | | | | | | | The `_PyThreadState_Bind()` function is called before the first `PyEval_AcquireThread()` so it's not synchronized with the stop the world GC. We had a race where `gc_visit_heaps()` might visit a thread's heap while it's being initialized. Use a simple atomic int to avoid visiting heaps for threads that are not yet fully initialized (i.e., before `tstate_mimalloc_bind()` is called). The race was reproducible by running: `python Lib/test/test_importlib/partial/pool_in_threads.py`.
* gh-94808: Reorganize _make_posargs and mark unused code (GH-119227)Mark Jason Dominus (陶敏修)2024-06-041-13/+21
| | | | | | | | | | | * Reorganize four-way if-elsif-elsif-elsif as nested if-elses * Mark unused branch in _make_posargs `names_with_default` is never `NULL`, even if there are no names with defaults. In that case it points to a structure with `size` zero. Rather than eliminating the branch, we leave it behind with an `assert(0)` in case a future change to the grammar exercises the branch.

* gh-117398: Use Per-Interpreter State for the _datetime Static Types (gh-119929)Eric Snow2024-06-0313-166/+381
| | | | | | | We make use of the same mechanism that we use for the static builtin types. This required a few tweaks. The relevant code could use some cleanup but I opted to avoid the significant churn in this change. I'll tackle that separately. This change is the final piece needed to make _datetime support multiple interpreters. I've updated the module slot accordingly.

* gh-117398: Add datetime Module State (gh-119810)Eric Snow2024-06-035-162/+376
| | | | | | | | | | | | I was able to make use of the existing datetime_state struct, but there was one tricky thing I had to sort out. We mostly aren't converting to heap types, so we can't use things like PyType_GetModuleByDef() to look up the module state. The solution I came up with is somewhat novel, but I consider it straightforward. Also, it shouldn't have much impact on performance. In summary, this main changes here are: * I've added some macros to help hide how various objects relate to module state * as a solution to the module state lookup problem, I've stored the last loaded module on the current interpreter's internal dict (actually a weakref) * if the static type method is used after the module has been deleted, it is reloaded * to avoid extra work when loading the module, we directly copy the objects (new refs only) from the old module state into the new state if the old module hasn't been deleted yet * during module init we set various objects on the static types' __dict__s; to simplify things, we only do that the first time; once those static types have a separate __dict__ per interpreter, we'll do it every time * we now clear the module state when the module is destroyed (before, we were leaking everything in _datetime_global_state)
* gh-117657: Fix race involving immortalizing objects (#119927)Sam Gross2024-06-039-44/+30
| | | | | | | | | The free-threaded build currently immortalizes objects that use deferred reference counting (see gh-117783). This typically happens once the first non-main thread is created, but the behavior can be suppressed for tests, in subinterpreters, or during a compile() call. This fixes a race condition involving the tracking of whether the behavior is suppressed.
