* gh-101758: Add _PyState_AddModule() Back for the Stable ABI (gh-101956)Eric Snow2023-02-161-0/+20
| | | | | | | We're adding the function back, only for the stable ABI symbol and not as any form of API. I had removed it yesterday. This undocumented "private" function was added with the implementation for PEP 3121 (3.0, 2007) for internal use and later moved out of the limited API (3.6, 2016) and then into the internal API (3.9, 2019). I removed it completely yesterday, including from the stable ABI manifest (where it was added because the symbol happened to be exported). It's unlikely that anyone is using _PyState_AddModule(), especially any stable ABI extensions built against 3.2-3.5, but we're playing it safe. https://github.com/python/cpython/issues/101758

* gh-99108: Refactor _sha256 & _sha512 into _sha2. (#101924)Gregory P. Smith2023-02-161-2/+1
| | | | | | | | | This merges their code. They're backed by the same single HACL* static library, having them be a single module simplifies maintenance. This should unbreak the wasm enscripten builds that currently fail due to linking in --whole-archive mode and the HACL* library appearing twice. Long unnoticed error fixed: _sha512.SHA384Type was doubly assigned and was actually SHA512Type. Nobody depends on those internal names. Also rename LIBHACL_ make vars to LIBHACL_SHA2_ in preperation for other future HACL things.
* gh-98627: Add an Optional Check for Extension Module Subinterpreter ↵Eric Snow2023-02-164-10/+120
| | | | | | | | | | | | | | | Compatibility (gh-99040) Enforcing (optionally) the restriction set by PEP 489 makes sense. Furthermore, this sets the stage for a potential restriction related to a per-interpreter GIL. This change includes the following: * add tests for extension module subinterpreter compatibility * add _PyInterpreterConfig.check_multi_interp_extensions * add Py_RTFLAGS_MULTI_INTERP_EXTENSIONS * add _PyImport_CheckSubinterpIncompatibleExtensionAllowed() * fail iff the module does not implement multi-phase init and the current interpreter is configured to check https://github.com/python/cpython/issues/98627

* 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-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
