| 8bea6c4 | Victor Stinner | 21 March 2024, 16:07:00 UTC | gh-115754: Add Py_GetConstant() function (#116883) Add Py_GetConstant() and Py_GetConstantBorrowed() functions. In the limited C API version 3.13, getting Py_None, Py_False, Py_True, Py_Ellipsis and Py_NotImplemented singletons is now implemented as function calls at the stable ABI level to hide implementation details. Getting these constants still return borrowed references.

This fixes some crashes when using multiprocessing and during shutdown when running with `PYTHON_GIL=0`. This also changes `PyOS_BeforeFork` to acquire the runtime lock (i.e., `HEAD_LOCK(&_PyRuntime)`) before forking to ensure that data protected by the runtime lock (and not just the GIL or stop-the-world) is in a consistent state before forking. | 21 March 2024, 14:01:16 UTC |

| dcaf33a | Petr Viktorin | 20 March 2024, 16:33:08 UTC | gh-114314: ctypes: remove stgdict and switch to heap types (GH-116458) Before this change, ctypes classes used a custom dict subclass, `StgDict`, as their `tp_dict`. This acts like a regular dict but also includes extra information about the type. This replaces stgdict by `StgInfo`, a C struct on the type, accessed by `PyObject_GetTypeData()` (PEP-697). All usage of `StgDict` (mainly variables named `stgdict`, `dict`, `edict` etc.) is converted to `StgInfo` (named `stginfo`, `info`, `einfo`, etc.). Where the dict is actually used for class attributes (as a regular PyDict), it's now called `attrdict`. This change -- not overriding `tp_dict` -- is made to make me comfortable with the next part of this PR: moving the initialization logic from `tp_new` to `tp_init`. The `StgInfo` is set up in `__init__` of each class, with a guard that prevents calling `__init__` more than once. Note that abstract classes (like `Array` or `Structure`) are created using `PyType_FromMetaclass` and do not have `__init__` called. Previously, this was done in `__new__`, which also wasn't called for abstract classes. Since `__init__` can be called from Python code or skipped, there is a tested guard to ensure `StgInfo` is initialized exactly once before it's used.

| 33da0e8 | mpage | 16 March 2024, 12:56:30 UTC | gh-114271: Fix race in `Thread.join()` (#114839) There is a race between when `Thread._tstate_lock` is released[^1] in `Thread._wait_for_tstate_lock()` and when `Thread._stop()` asserts[^2] that it is unlocked. Consider the following execution involving threads A, B, and C: 1. A starts. 2. B joins A, blocking on its `_tstate_lock`. 3. C joins A, blocking on its `_tstate_lock`. 4. A finishes and releases its `_tstate_lock`. 5. B acquires A's `_tstate_lock` in `_wait_for_tstate_lock()`, releases it, but is swapped out before calling `_stop()`. 6. C is scheduled, acquires A's `_tstate_lock` in `_wait_for_tstate_lock()` but is swapped out before releasing it. 7. B is scheduled, calls `_stop()`, which asserts that A's `_tstate_lock` is not held. However, C holds it, so the assertion fails. The race can be reproduced[^3] by inserting sleeps at the appropriate points in the threading code. To do so, run the `repro_join_race.py` from the linked repo. There are two main parts to this PR: 1. `_tstate_lock` is replaced with an event that is attached to `PyThreadState`. The event is set by the runtime prior to the thread being cleared (in the same place that `_tstate_lock` was released). `Thread.join()` blocks waiting for the event to be set. 2. `_PyInterpreterState_WaitForThreads()` provides the ability to wait for all non-daemon threads to exit. To do so, an `is_daemon` predicate was added to `PyThreadState`. This field is set each time a thread is created. `threading._shutdown()` now calls into `_PyInterpreterState_WaitForThreads()` instead of waiting on `_tstate_lock`s.
