Gregory P. Smith	b8d3fddba6	gh-70647: Better promote how to safely parse yearless dates in datetime. (GH-116179) ... * gh-70647: Better promote how to safely parse yearless dates in datetime. Every four years people encounter this because it just isn't obvious. This moves the footnote up to a note with a code example. We'd love to change the default year value for datetime but doing that could have other consequences for existing code. This documented workaround *always* works. * doctest code within note is bad, dedent. * Update to match the error message. * remove no longer referenced footnote * ignore the warning in the doctest * use Petr's suggestion for the docs to hide the warning processing * cover date.strptime (3.14) as well	2025-12-20 22:47:40 -08:00

Sam Gross	e46f28c6af	gh-129069: Fix listobject.c data races due to memmove (gh-142957) ... The use of memmove and _Py_memory_repeat were not thread-safe in the free threading build in some cases. In theory, memmove and _Py_memory_repeat can copy byte-by-byte instead of pointer-by-pointer, so concurrent readers could see uninitialized data or tearing. Additionally, we should be using "release" (or stronger) ordering to be compliant with the C11 memory model when copying objects within a list.	2025-12-19 18:06:47 -05:00
Sam Gross	4ea3c1a047	gh-120321: Fix TSan reported race in gen_clear_frame (gh-142995) ... TSan treats compare-exchanges that fail as if they are writes so there is a false positive with the read of gi_frame_state in gen_close.	2025-12-19 17:33:49 -05:00
Sam Gross	08bc03ff2a	gh-120321: Make gi_frame_state transitions atomic in FT build (gh-142599) ... This makes generator frame state transitions atomic in the free threading build, which avoids segfaults when trying to execute a generator from multiple threads concurrently. There are still a few operations that aren't thread-safe and may crash if performed concurrently on the same generator/coroutine: * Accessing gi_yieldfrom/cr_await/ag_await * Accessing gi_frame/cr_frame/ag_frame * Async generator operations	2025-12-19 19:10:37 +00:00

Andrej	610aabfef2	gh-142527: Docs: Clarify that random.seed() discards the sign of an integer input (#142483) ... If *a* is an integer, the sign of *a* is discarded in the C source code. Clarify this behavior to prevent foot guns, where a common use case might naively assume that flipping the sign will produce different sequences (e.g. for a train/test split of a synthetic data generator in machine learning).

Sam Gross	f54d44d333	gh-129068: Make range iterators thread-safe (gh-142886) ... Now that we specialize range iteration in the interpreter for the common case where the iterator has only one reference, there's not a significant performance cost to making the iteration thread-safe.	2025-12-18 13:11:51 -05:00

ivonastojanovic	cbc0851ada	gh-138122: Improve bytecode panel (#142910) ... The bytecode panel appears when a user generates a heatmap with --opcodes and clicks the button to unfold a line and display the bytecode instructions. Currently, an empty space appears on the left where the line number, self, and total columns are displayed. This area should instead extend those columns, rather than leaving a gap.	2025-12-18 11:43:39 +00:00
