* gh-91962: Fix `hstrerror` detection issues on Solaris (GH-91963)Jakub Kulík2024-10-301-3/+0

* gh-125206: Bug in ctypes with old libffi is fixed (#125322)Mikhail Efimov2024-10-151-0/+3
| | | | | | Workaround for old libffi versions is added. Module ctypes now supports C11 double complex only with libffi >= 3.3.0. Co-authored-by: Sergey B Kirpichev <skirpichev@gmail.com>
* gh-124944: Add socket.SO_ORIGINAL_DST (#124945)Steven Jin2024-10-141-0/+3

* gh-123990: Good bye WITH_FREELISTS macro (gh-124358)Donghee Na2024-09-241-3/+0

* gh-122272: Guarantee specifiers %F and %C for datetime.strftime to be ↵blhsing2024-08-231-0/+3
| | | | 0-padded (GH-122436)
* gh-99108: Add HACL* Blake2 implementation to hashlib (GH-119316)Jonathan Protzenko2024-08-131-3/+6
| | | | | | | This replaces the existing hashlib Blake2 module with a single implementation that uses HACL\*'s Blake2b/Blake2s implementations. We added support for all the modes exposed by the Python API, including tree hashing, leaf nodes, and so on. We ported and merged all of these changes upstream in HACL\*, added test vectors based on Python's existing implementation, and exposed everything needed for hashlib. This was joint work done with @R1kM. See the PR for much discussion and benchmarking details. TL;DR: On many systems, 8-50% faster (!) than `libb2`, on some systems it appeared 10-20% slower than `libb2`.
* gh-61103: Support double complex (_Complex) type in ctypes (#120894)Sergey B Kirpichev2024-07-011-0/+3
| | | | | | | | | | | | | | | | | | Example: ```pycon >>> import ctypes >>> ctypes.__STDC_IEC_559_COMPLEX__ 1 >>> libm = ctypes.CDLL('libm.so.6') >>> libm.clog.argtypes = [ctypes.c_double_complex] >>> libm.clog.restype = ctypes.c_double_complex >>> libm.clog(1+1j) (0.34657359027997264+0.7853981633974483j) ``` Co-authored-by: Nice Zombies <nineteendo19d0@gmail.com> Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com> Co-authored-by: Victor Stinner <vstinner@python.org>
* gh-113565: Improve and harden detection of curses dependencies (#119816)Erlend E. Aasland2024-07-011-1/+28
| | | | | | | | | | | | | | 1. Use pkg-config to check for ncursesw/panelw. If that fails, use pkg-config to check for ncurses/panel. 2. Regardless of pkg-config output, search for curses/panel headers, so we're sure we have all defines in pyconfig.h. 3. Regardless of pkg-config output, check if libncurses or libncursesw contains the 'initscr' symbol; if it does _and_ pkg-config failed earlier, add the resulting -llib linker option to CURSES_LIBS. Ditto for 'update_panels' and PANEL_LIBS. 4. Wrap the rest of the checks with WITH_SAVE_ENV and make sure we're using updated LIBS and CPPFLAGS for those. Add the PY_CHECK_CURSES convenience macro.

* gh-117845: Detect libedit hook function signature in configure (#117870)Joshua Root2024-04-171-0/+3
| | | | | | Older libedit versions (like Apple's) use a different type signature for rl_startup_hook and rl_pre_input_hook. Add a configure check to determine which signature is accepted by introducing the Py_RL_STARTUP_HOOK_TAKES_ARGS macro in pyconfig.h.
* gh-115765: Don't use deprecated AC_EGREP_* macros in configure.ac (#116016)Erlend E. Aasland2024-02-281-1/+4
| | | Rewrite using AX_CHECK_DEFINE and AC_CHECK_TYPES.
* gh-115773: Add tests to exercise the _Py_DebugOffsets structure (#115774)Pablo Galindo Salgado2024-02-281-0/+3

* gh-115765: Don't use deprecated AC_CHECK_TYPE macro in configure.ac (#115792)Erlend E. Aasland2024-02-221-3/+9

| | | | | | | available (#112616) Add a configure define for HAVE_PTHREAD_COND_TIMEDWAIT_RELATIVE_NP and replaces pthread_cond_timedwait() with pthread_cond_timedwait_relative_np() for relative time when supported in semaphore waiting logic.

* gh-113117: Support posix_spawn in subprocess.Popen with close_fds=True (#113118)Jakub Kulík2023-12-171-0/+4
| | | | | | | | Add support for `os.POSIX_SPAWN_CLOSEFROM` and `posix_spawn_file_actions_addclosefrom_np` and have the `subprocess` module use them when available. This means `posix_spawn` can now be used in the default `close_fds=True` situation on many platforms. Co-authored-by: Gregory P. Smith [Google LLC] <greg@krypto.org>
* gh-112970: Detect and use closefrom() when available (#112969)Sam James2023-12-121-0/+3
| | | | | | | | | | | glibc-2.34 implements closefrom(3) using the same semantics as on BSD. Check for closefrom() in configure and use the check result in fileutils.c, rather than hardcoding a FreeBSD check. Some implementations of closefrom() return an int. Explicitly discard the return value by casting it to void, to avoid future compiler warnings. Signed-off-by: Sam James <sam@gentoo.org>

* 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>

* gh-108765: Python.h no longer includes <ieeefp.h> (#108781)Victor Stinner2023-09-021-3/+0
| | | | 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.

* 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.
