* GH-116422: Tier2 hot/cold splitting (GH-116813)Mark Shannon2024-03-267-54/+122
| | | | | Splits the "cold" path, deopts and exits, from the "hot" path, reducing the size of most jitted instructions, at the cost of slower exits.
* gh-116996: Add pystats about _Py_uop_analyse_and_optimize (GH-116997)Michael Droettboom2024-03-211-0/+26
|
* gh-76785: Drop PyInterpreterID_Type (gh-117101)Eric Snow2024-03-211-1/+0
| | | I added it quite a while ago as a strategy for managing interpreter lifetimes relative to the PEP 554 (now 734) implementation. Relatively recently I refactored that implementation to no longer rely on InterpreterID objects. Thus now I'm removing it.
* gh-115754: Add Py_GetConstant() function (#116883)Victor Stinner2024-03-211-0/+1
| | | | | | | | | | | | Add Py_GetConstant() and Py_GetConstantBorrowed() functions. In the limited C API version 3.13, getting Py_None, Py_False, Py_True, Py_Ellipsis and Py_NotImplemented singletons is now implemented as function calls at the stable ABI level to hide implementation details. Getting these constants still return borrowed references. Add _testlimitedcapi/object.c and test_capi/test_object.py to test Py_GetConstant() and Py_GetConstantBorrowed() functions.
* GH-108362: Incremental Cycle GC (GH-116206)Mark Shannon2024-03-201-2/+5
|
* GH-116017: Put JIT code and data on the same page (GH-116845)Brandt Bucher2024-03-192-5/+4
|
* gh-108716: Cleanup remaining deepfreeze infrastructure (#116919)Guido van Rossum2024-03-181-77/+2
| | | | | Keep Tools/build/deepfreeze.py around (we may repurpose it for deepfreezing non-code objects), and keep basic "clean" targets that remove the output of former deep-freeze activities, to keep the build directories of current devs clean.
* gh-116879: Add new optimizer pystats to tables (GH-116880)Michael Droettboom2024-03-161-4/+30
|
* gh-112536: Add --tsan test for reasonable TSAN execution times. (gh-116601)Donghee Na2024-03-151-0/+5
|
* gh-85283: Build pwd extension with the limited C API (#116841)Victor Stinner2024-03-151-5/+4
| | | | Argument Clinic now uses the PEP 737 "%T" format to format type name for the limited C API.
* gh-113317, AC: Add libclinic.converter module (#116821)Victor Stinner2024-03-144-601/+621
| | | | | * Move CConverter class to a new libclinic.converter module. * Move CRenderData and Include classes to a new libclinic.crenderdata module.
* gh-113317, AC: Add libclinic.block_parser module (#116819)Victor Stinner2024-03-143-336/+361
| | | | | | * Move Block and BlockParser classes to a new libclinic.block_parser module. * Move Language and PythonLanguage classes to a new libclinic.language module.
* gh-113317, AC: Add libclinic.function (#116807)Victor Stinner2024-03-144-241/+270
| | | | | | Move Module, Class, Function and Parameter classes to a new libclinic.function module. Move VersionTuple and Sentinels to libclinic.utils.
* gh-116646, AC: Always use PyObject_AsFileDescriptor() in fildes (#116806)Victor Stinner2024-03-141-10/+7
| | | | | | | The fildes converter of Argument Clinic now always call PyObject_AsFileDescriptor(), not only for the limited C API. The _PyLong_FileDescriptor_Converter() converter stays as a fallback when PyObject_AsFileDescriptor() cannot be used.
* gh-116646, AC: Add CConverter.use_converter() method (#116793)Victor Stinner2024-03-141-6/+35
| | | Only add includes when the converter is effectively used.
* gh-116646: Add limited C API support to AC fildes converter (#116769)Victor Stinner2024-03-141-12/+13
| | | Add tests on the "fildes" converter to _testclinic_limited.
* gh-113317, AC: Move warn() and fail() to libclinic.errors (#116770)Victor Stinner2024-03-143-47/+51
|
* gh-115419: Change default sym to not_null (GH-116562)Ken Jin2024-03-131-2/+2
|
* gh-85283: Convert grp extension to the limited C API (#116611)Victor Stinner2024-03-121-0/+2
| | | | posixmodule.h: remove check on the limited C API, since these helpers are not part of the public C API.
* gh-108494: Fix Argument Clinic LIMITED_CAPI_REGEX (#116610)Victor Stinner2024-03-111-2/+3
| | | Accept spaces in "# define Py_LIMITED_API 0x030d0000".

* gh-116417: Fix make check-c-globals for _testlimitedcapi (#116570)Victor Stinner2024-03-102-1/+1
| | | | | * Remove unused '_testcapimodule' global in Modules/_testcapi/unicode.c. * Update c-analyzer to not use the internal C API in _testlimitedcapi.c.
* gh-116417: Avoid PyFloat_AS_DOUBLE() in AC limited C API (#116568)Victor Stinner2024-03-101-18/+36
| | | | Argument Clinic no longer calls PyFloat_AS_DOUBLE() when the usage of the limited C API is requested.
* gh-116000: Make optimizer_generator.py work without any arguments (#116470)Kirill Podoprigora2024-03-071-5/+8
|
* gh-116417: Add _testlimitedcapi C extension (#116419)Victor Stinner2024-03-073-3/+4
| | | | | | | | | | | | | Add a new C extension "_testlimitedcapi" which is only built with the limited C API. Move heaptype_relative.c and vectorcall_limited.c from Modules/_testcapi/ to Modules/_testlimitedcapi/. * configure: add _testlimitedcapi test extension. * Update generate_stdlib_module_names.py. * Update make check-c-globals.

* gh-116088: Insert bottom checks after all sym_set_...() calls (#116089)Guido van Rossum2024-02-291-4/+0
| | | | | | | | | This changes the `sym_set_...()` functions to return a `bool` which is `false` when the symbol is `bottom` after the operation. All calls to such functions now check this result and go to `hit_bottom`, a special error label that prints a different message and then reports that it wasn't able to optimize the trace. No executor will be produced in this case.
