* gh-59956: Partial Fix for GILState API Compatibility with Subinterpreters ↵Eric Snow2023-02-061-21/+4
| | | | | | | | | | | (gh-101431) The GILState API (PEP 311) implementation from 2003 made the assumption that only one thread state would ever be used for any given OS thread, explicitly disregarding the case of subinterpreters. However, PyThreadState_Swap() still facilitated switching between subinterpreters, meaning the "current" thread state (holding the GIL), and the GILState thread state could end up out of sync, causing problems (including crashes). This change addresses the issue by keeping the two in sync in PyThreadState_Swap(). I verified the fix against gh-99040. Note that the other GILState-subinterpreter incompatibility (with autoInterpreterState) is not resolved here. https://github.com/python/cpython/issues/59956

* gh-59956: Clarify Runtime State Status Expectations (gh-101308)Eric Snow2023-01-303-149/+387
| | | | | | | | | | | | | A PyThreadState can be in one of many states in its lifecycle, represented by some status value. Those statuses haven't been particularly clear, so we're addressing that here. Specifically: * made the distinct lifecycle statuses clear on PyThreadState * identified expectations of how various lifecycle-related functions relate to status * noted the various places where those expectations don't match the actual behavior At some point we'll need to address the mismatches. (This change also includes some cleanup.) https://github.com/python/cpython/issues/59956

| | | | | `warnings.warn()` gains the ability to skip stack frames based on code filename prefix rather than only a numeric `stacklevel=` via a new `skip_file_prefixes=` keyword argument.

* gh-59956: Allow the "Trashcan" Mechanism to Work Without a Thread State ↵Eric Snow2023-01-231-0/+16
| | | | | | | | | | | | (gh-101209) We've factored out a struct from the two PyThreadState fields. This accomplishes two things: * make it clear that the trashcan-related code doesn't need any other parts of PyThreadState * allows us to use the trashcan mechanism even when there isn't a "current" thread state We still expect the caller to hold the GIL. https://github.com/python/cpython/issues/59956

* gh-59956: Fix Function Groupings in pystate.c (gh-101172)Eric Snow2023-01-201-237/+352
| | | | | This is a follow-up to gh-101161. The objective is to make it easier to read Python/pystate.c by grouping the functions there in a consistent way. This exclusively involves moving code around and adding various kinds of comments. https://github.com/python/cpython/issues/59956

* gh-59956: Clarify GILState-related Code (gh-101161)Eric Snow2023-01-193-219/+344
| | | | | | | | | | The objective of this change is to help make the GILState-related code easier to understand. This mostly involves moving code around and some semantically equivalent refactors. However, there are a also a small number of slight changes in structure and behavior: * tstate_current is moved out of _PyRuntimeState.gilstate * autoTSSkey is moved out of _PyRuntimeState.gilstate * autoTSSkey is initialized earlier * autoTSSkey is re-initialized (after fork) earlier https://github.com/python/cpython/issues/59956
