Ken Jin	695ab61351	gh-132732: Automatically constant evaluate pure operations (GH-132733) ... This adds a "macro" to the optimizer DSL called "REPLACE_OPCODE_IF_EVALUATES_PURE", which allows automatically constant evaluating a bytecode body if certain inputs have no side effects upon evaluations (such as ints, strings, and floats).

Kattni	ac9d37c60b	patchcheck: use URL paths to identify upstream remote (GH-135806) ... * find defined "(fetch)" remotes with "python/cpython" in their URL * if there is exactly one, use that remote name * if there is one named "upstream", "origin", or "python", use that remote (in that precedence order) * otherwise report an error listing the defined remotes	2025-06-22 04:51:23 +00:00

Ken Jin	fba5dded6d	gh-134584: Decref elimination for float ops in the JIT (GH-134588) ... This PR adds a PyJitRef API to the JIT's optimizer that mimics the _PyStackRef API. This allows it to track references and their stack lifetimes properly. Thus opening up the doorway to refcount elimination in the JIT.	2025-06-17 23:25:53 +08:00
Mark Shannon	8dd8b5c2f0	GH-135379: Support limited scalar replacement for replicated uops in the JIT code generator. (GH-135563) ... * Use it to support efficient specializations of COPY and SWAP in the JIT.	2025-06-17 13:43:09 +01:00

Michał Górny	0d582def34	gh-134632: Fix build-details.json to use INCLUDEPY path (#134633) ... * gh-134632: Fix `build-details.json` to use `INCLUDEPY` path Fix ``build-details.json`` generation to use ``INCLUDEPY``, in order to reference the ``pythonX.Y`` subdirectory of the include directory, as required in :pep:`739`, instead of the top-level include directory. * test_build_details: Add tests for the c_api section * test_build_details: Expect pkgconfig for CPython unconditionally	2025-06-17 08:05:04 +00:00
Ken Jin	7b15873ed0	gh-135474: Specialize arithmetic only on compact ints (GH-135479) ... Specialize arithmetic only on compact ints. This also makes int operations non-escaping in the JIT and in tier 1.	2025-06-14 17:13:32 +08:00

Neil Schemenauer	fbbbc10055	gh-127266: avoid data races when updating type slots (gh-133177) ... In the free-threaded build, avoid data races caused by updating type slots or type flags after the type was initially created. For those (typically rare) cases, use the stop-the-world mechanism. Remove the use of atomics when reading or writing type flags.	2025-05-27 18:27:41 -07:00
Kumar Aditya	a380d57873	gh-134043: use stackrefs in vectorcalling methods (#134044) ... Adds `_PyObject_GetMethodStackRef` which uses stackrefs and takes advantage of deferred reference counting in free-threading while calling method objects in vectorcall.	2025-05-27 22:28:27 +05:30
Emma Smith	3f9eb55e09	gh-134262: increase retries in Tools/build/generate_sbom.py (#134558)	2025-05-27 19:02:17 +03:00
Mark Shannon	f6f4e8a662	GH-132554: "Virtual" iterators (GH-132555) ... * FOR_ITER now pushes either the iterator and NULL or leaves the iterable and pushes tagged zero * NEXT_ITER uses the tagged int as the index into the sequence or, if TOS is NULL, iterates as before.	2025-05-27 15:59:45 +01:00

Peter Bierma	b8998fe2d8	gh-131185: Use a proper thread-local for cached thread states (gh-132510) ... Switches over to a _Py_thread_local in place of autoTssKey, and also fixes a few other checks regarding PyGILState_Ensure after finalization. Note that this doesn't fix concurrent use of PyGILState_Ensure with Py_Finalize; I'm pretty sure zapthreads doesn't work at all, and that needs to be fixed seperately.	2025-05-21 07:01:25 -06:00

Steve Dower	986c367028	gh-133779: Revert Windows generation of pyconfig.h and go back to a static header. (GH-133966) ... Extension builders must specify Py_GIL_DISABLED if they want to link to the free-threaded builds. This was usually the case already, but this change guarantees it in all circumstances.	2025-05-19 11:35:22 +01:00
