* gh-91325: Skip Stable ABI checks with Py_TRACE_REFS special build (GH-92046)Petr Viktorin2024-01-291-9/+10
| | | | | | Skip Stable ABI checks with Py_TRACE_REFS special build This build is not compatible with Py_LIMITED_API nor with the stable ABI.

* GH-112354: `END_FOR` instruction to only pop one value. (GH-114247)Mark Shannon2024-01-241-0/+8
| | | | * Compiler emits END_FOR; POP_TOP instead of END_FOR. To support tier 2 side exits in loops.

* gh-113258: Write frozen modules to the build tree on Windows (GH-113303)Itamar Oren2024-01-031-4/+4
| | | This ensures the source directory is not modified at build time, and different builds (e.g. different versions or GIL vs no-GIL) do not have conflicts.

* gh-76785: More Fixes for test.support.interpreters (gh-113012)Eric Snow2023-12-121-0/+1
| | | This brings the module (along with the associated extension modules) mostly in sync with PEP 734. There are only a few small things to wrap up.

* gh-112088: Run autoreconf in GHA check_generated_files (#112090)Victor Stinner2023-11-151-0/+31
| | | | | | | | | | | The "Check if generated files are up to date" job of GitHub Actions now runs the "autoreconf -ivf -Werror" command instead of the "make regen-configure" command to avoid depending on the external quay.io server. Add Tools/build/regen-configure.sh script to regenerate the configure with an Ubuntu container image. The "quay.io/tiran/cpython_autoconf:271" container image (https://github.com/tiran/cpython_autoconf) is no longer used.

* gh-90815: Add mimalloc memory allocator (#109914)Dino Viehland2023-10-301-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add mimalloc v2.12 Modified src/alloc.c to remove include of alloc-override.c and not compile new handler. Did not include the following files: - include/mimalloc-new-delete.h - include/mimalloc-override.h - src/alloc-override-osx.c - src/alloc-override.c - src/static.c - src/region.c mimalloc is thread safe and shares a single heap across all runtimes, therefore finalization and getting global allocated blocks across all runtimes is different. * mimalloc: minimal changes for use in Python: - remove debug spam for freeing large allocations - use same bytes (0xDD) for freed allocations in CPython and mimalloc This is important for the test_capi debug memory tests * Don't export mimalloc symbol in libpython. * Enable mimalloc as Python allocator option. * Add mimalloc MIT license. * Log mimalloc in Lib/test/pythoninfo.py. * Document new mimalloc support. * Use macro defs for exports as done in: https://github.com/python/cpython/pull/31164/ Co-authored-by: Sam Gross <colesbury@gmail.com> Co-authored-by: Christian Heimes <christian@python.org> Co-authored-by: Victor Stinner <vstinner@python.org>
* gh-110014: Fix _POSIX_THREADS and _POSIX_SEMAPHORES usage (#110139)Victor Stinner2023-09-301-1/+6
| | | | | | | | | | | | | | | | * pycore_pythread.h is now the central place to make sure that _POSIX_THREADS and _POSIX_SEMAPHORES macros are defined if available. * Make sure that pycore_pythread.h is included when _POSIX_THREADS and _POSIX_SEMAPHORES macros are tested. * PY_TIMEOUT_MAX is now defined as a constant, since its value depends on _POSIX_THREADS, instead of being defined as a macro. * Prevent integer overflow in the preprocessor when computing PY_TIMEOUT_MAX_VALUE on Windows: replace "0xFFFFFFFELL * 1000 < LLONG_MAX" with "0xFFFFFFFELL < LLONG_MAX / 1000". * Document the change and give hints how to fix affected code. * Add an exception for PY_TIMEOUT_MAX name to smelly.py * Add PY_TIMEOUT_MAX to the stable ABI

* gh-108740: Fix "make regen-all" race condition (#108741)Victor Stinner2023-09-061-1/+1
| | | | | | | | | | | | | | | | | | Fix a race condition in "make regen-all". The deepfreeze.c source and files generated by Argument Clinic are now generated or updated before generating "global objects". Previously, some identifiers may miss depending on the order in which these files were generated. * "make regen-global-objects": Make sure that deepfreeze.c is generated and up to date, and always run "make clinic". * "make clinic" no longer runs generate_global_objects.py script. * "make regen-deepfreeze" now only updates deepfreeze.c (C file). It doesn't build deepfreeze.o (object) anymore. * Remove misleading messages in "make regen-global-objects" and "make clinic". They are now outdated, these commands are now safe to use. * Document generates files in Doc/using/configure.rst. Co-authored-by: Erlend E. Aasland <erlend@python.org>

* gh-108494: Argument Clinic partial supports of Limited C API (#108495)Victor Stinner2023-08-251-0/+1
| | | | | | | | | | Argument Clinic now has a partial support of the Limited API: * Add --limited option to clinic.c. * Add '_testclinic_limited' extension which is built with the limited C API version 3.13. * For now, hardcode in clinic.py that "_testclinic_limited.c" targets the limited C API.
* gh-107211: No longer export internal functions (7) (#108425)Victor Stinner2023-08-241-2/+2
| | | | | | | | | No longer export _PyUnicode_FromId() internal C API function. Change comment style to "// comment" and add comment explaining why other functions have to be exported. Update Tools/build/generate_token.py to update Include/internal/pycore_token.h comments.

* gh-106931: Intern Statically Allocated Strings Globally (gh-107272)Eric Snow2023-07-271-0/+2
| | | | | We tried this before with a dict and for all interned strings. That ran into problems due to interpreter isolation. However, exclusively using a per-interpreter cache caused some inconsistency that can eliminate the benefit of interning. Here we circle back to using a global cache, but only for statically allocated strings. We also use a more-basic _Py_hashtable_t for that global cache instead of a dict. Ideally we would only have the global cache, but the optional isolation of each interpreter's allocator means that a non-static string object must not outlive its interpreter. Thus we would have to store a copy of each such interned string in the global cache, tied to the main interpreter.

| | | | | | | | | | | | | | | | | Remove the "cpython/pytime.h" header file: it only contained private functions. Move functions to the internal pycore_time.h header file. Move tests from _testcapi to _testinternalcapi. Rename also test methods to have the same name than tested C functions. No longer export these functions: * _PyTime_Add() * _PyTime_As100Nanoseconds() * _PyTime_FromMicrosecondsClamp() * _PyTime_FromTimespec() * _PyTime_FromTimeval() * _PyTime_GetPerfCounterWithInfo() * _PyTime_MulDiv()
