* gh-101758: Add a Test For Single-Phase Init Modules in Multiple Interpreters ↵Eric Snow2023-02-151-2/+74
| | | | | | | (gh-101920) The test verifies the behavior of single-phase init modules when loaded in multiple interpreters. https://github.com/python/cpython/issues/101758
* gh-101758: Clean Up Uses of Import State (gh-101919)Eric Snow2023-02-159-987/+1363
| | | | | | | | | | | | | | | This change is almost entirely moving code around and hiding import state behind internal API. We introduce no changes to behavior, nor to non-internal API. (Since there was already going to be a lot of churn, I took this as an opportunity to re-organize import.c into topically-grouped sections of code.) The motivation is to simplify a number of upcoming changes. Specific changes: * move existing import-related code to import.c, wherever possible * add internal API for interacting with import state (both global and per-interpreter) * use only API outside of import.c (to limit churn there when changing the location, etc.) * consolidate the import-related state of PyInterpreterState into a single struct field (this changes layout slightly) * add macros for import state in import.c (to simplify changing the location) * group code in import.c into sections *remove _PyState_AddModule() https://github.com/python/cpython/issues/101758

* gh-101758: Add a Test For Single-Phase Init Module Variants (gh-101891)Eric Snow2023-02-141-10/+95

* 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

| | | | | | | | | | | | (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

| | | | | 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
