* gh-102654: Insert #line directives in generated_cases.c.h (#102669)Guido van Rossum2023-03-151-0/+456
| | | | | | | | | This behavior is optional, because in some extreme cases it may just make debugging harder. The tool defaults it to off, but it is on in Makefile.pre.in. Also note that this makes diffs to generated_cases.c.h noisier, since whenever you insert or delete a line in bytecodes.c, all subsequent #line directives will change.

* gh-102660: Handle m_copy Specially for the sys and builtins Modules (gh-102661)Eric Snow2023-03-144-4/+43
| | | | | | | It doesn't make sense to use multi-phase init for these modules. Using a per-interpreter "m_copy" (instead of PyModuleDef.m_base.m_copy) makes this work okay. (This came up while working on gh-101660.) Note that we might instead end up disallowing re-load for sys/builtins since they are so special. https://github.com/python/cpython/issues/102660

* gh-102255: Improve build support for Windows API partitions (GH-102256)Max Bachmann2023-03-094-5/+98
| | | | | Add `MS_WINDOWS_DESKTOP`, `MS_WINDOWS_APPS`, `MS_WINDOWS_SYSTEM` and `MS_WINDOWS_GAMES` preprocessor definitions to allow switching off functionality missing from particular API partitions ("partitions" are used in Windows to identify overlapping subsets of APIs). CPython only officially supports `MS_WINDOWS_DESKTOP` and `MS_WINDOWS_SYSTEM` (APPS is included by normal desktop builds, but APPS without DESKTOP is not covered). Other configurations are a convenience for people building their own runtimes. `MS_WINDOWS_GAMES` is for the Xbox subset of the Windows API, which is also available on client OS, but is restricted compared to `MS_WINDOWS_DESKTOP`. These restrictions may change over time, as they relate to the build headers rather than the OS support, and so we assume that Xbox builds will use the latest available version of the GDK.
* gh-100227: Isolate the Import State to Each Interpreter (gh-101941)Eric Snow2023-03-091-44/+54
| | | | | | | | | | | | Specific changes: * move the import lock to PyInterpreterState * move the "find_and_load" diagnostic state to PyInterpreterState Note that the import lock exists to keep multiple imports of the same module in the same interpreter (but in different threads) from stomping on each other. Independently, we use a distinct global lock to protect globally shared import state, especially related to loaded extension modules. For now we can rely on the GIL as that lock but with a per-interpreter GIL we'll need a new global lock. The remaining state in _PyRuntimeState.imports will (probably) continue being global. https://github.com/python/cpython/issues/100227

* gh-90110: Fix the c-analyzer Tool (#102483)Eric Snow2023-03-071-2/+2
| | | | | | | Some incompatible changes had gone in, and the "ignore" lists weren't properly undated. This change fixes that. It's necessary prior to enabling test_check_c_globals, which I hope to do soon. Note that this does include moving last_resort_memory_error to PyInterpreterState. https://github.com/python/cpython/issues/90110

* gh-102251: Updates to test_imp Toward Fixing Some Refleaks (gh-102254)Eric Snow2023-02-271-4/+111
| | | | | | | This is related to fixing the refleaks introduced by commit 096d009. I haven't been able to find the leak yet, but these changes are a consequence of that effort. This includes some cleanup, some tweaks to the existing tests, and a bunch of new test cases. The only change here that might have impact outside the tests in question is in imp.py, where I update imp.load_dynamic() to use spec_from_file_location() instead of creating a ModuleSpec directly. Also note that I've updated the tests to only skip if we're checking for refleaks (regrtest's --huntrleaks), whereas in gh-101969 I had skipped the tests entirely. The tests will be useful for some upcoming work and I'd rather the refleaks not hold that up. (It isn't clear how quickly we'll be able to fix the leaking code, though it will certainly be done in the short term.) https://github.com/python/cpython/issues/102251

* 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
