* gh-90815: Add mimalloc memory allocator (#109914)Dino Viehland2023-10-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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>

| | | | Remove also the HAVE_IEEEFP_H macro: remove ieeefp.h from the AC_CHECK_HEADERS() check of configure.ac.
* gh-108223: Add --disable-gil to configure (gh-108227)Sam Gross2023-08-211-0/+3
| | | | | The `--disable-gil` flags does not do anything yet other than define the Py_NOGIL macro. This is intended to support setting up additional buildbots.

| | | | | | | Quoting autoconf (v2.71): All current systems provide time.h; it need not be checked for. Not all systems provide sys/time.h, but those that do, all allow you to include it and time.h simultaneously.

| | | | | | | :warning: :warning: Note for reviewers, hackers and fellow systems/low-level/compiler engineers :warning: :warning: If you have a lot of experience with this kind of shenanigans and want to improve the **first** version, **please make a PR against my branch** or **reach out by email** or **suggest code changes directly on GitHub**. If you have any **refinements or optimizations** please, wait until the first version is merged before starting hacking or proposing those so we can keep this PR productive.

* bpo-40514: Drop EXPERIMENTAL_ISOLATED_SUBINTERPRETERS (gh-93185)Eric Snow2022-05-271-3/+0
| | | | | | | This was added for bpo-40514 (gh-84694) to test out a per-interpreter GIL. However, it has since proven unnecessary to keep the experiment in the repo. (It can be done as a branch in a fork like normal.) So here we are removing: * the configure option * the macro * the code enabled by the macro
* GH-93207: Remove HAVE_STDARG_PROTOTYPES configure check for stdarg.h (#93215)Kumar Aditya2022-05-271-4/+0
|
* gh-93202: Always use %zd printf formatter (#93201)Victor Stinner2022-05-251-3/+0
| | | | | | | | | | | | | | | | Python now always use the ``%zu`` and ``%zd`` printf formats to format a size_t or Py_ssize_t number. Building Python 3.12 requires a C11 compiler, so these printf formats are now always supported. * PyObject_Print() and _PyObject_Dump() now use the printf %zd format to display an object reference count. * Update PY_FORMAT_SIZE_T comment. * Remove outdated notes about the %zd format in PyBytes_FromFormat() and PyUnicode_FromFormat() documentations. * configure no longer checks for the %zd format and no longer defines PY_FORMAT_SIZE_T macro in pyconfig.h. * pymacconfig.h no longer undefines PY_FORMAT_SIZE_T: macOS 10.4 is no longer supported. Python 3.12 now requires macOS 10.6 (Snow Leopard) or newer.

* bpo-46968: Fix faulthandler for Sapphire Rapids Xeon (GH-31789)Oleksandr Pavlyk2022-03-111-0/+3
| | | | | | | | | | | In Linux kernel 5.14 one can dynamically request size of altstacksize based on hardware capabilities with getauxval(AT_MINSIGSTKSZ). This changes allows for Python extension's request to Linux kernel to use AMX_TILE instruction set on Sapphire Rapids Xeon processor to succeed, unblocking use of the ISA in frameworks. Introduced HAVE_LINUX_AUXVEC_H in configure.ac and pyconfig.h.in Used cpython_autoconf:269 docker container to generate configure.
