* gh-93491: Add support tier detection to configure (GH-93492)Christian Heimes2022-06-101-0/+3
| | | | | Co-authored-by: Adam Turner <9087854+AA-Turner@users.noreply.github.com> Co-authored-by: Steve Dower <steve.dower@microsoft.com> Co-authored-by: Erlend Egeberg Aasland <erlend.aasland@protonmail.com>
* gh-93475: Expose FICLONE and FICLONERANGE constants in fcntl (#93478)Illia Volochii2022-06-061-0/+3

* 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 * Remove outdated notes about the %zd format in PyBytes_FromFormat() and PyUnicode_FromFormat() documentations.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-41818: Add os.login_tty() for *nix. (#29658)Soumendra Ganguly2022-05-051-0/+6

| | | | | - Remove ``--with-tclk-*`` options from `configure` - Use pkg-config to detect `_tkinter` dependencies (Tcl/Tk, X11) - Manual override via environment variables `TCLTK_CFLAGS` and `TCLTK_LIBS`

* 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.

* bpo-45723: Add helper macros and more caching to configure.ac (GH-29429)Christian Heimes2021-11-081-7/+7
| | | | | | | | | | | | | | | | | Almost all checks are now cached by AC_CACHE_CHECK(). Common patterns are replaced by helper macros. Variable names now use naming scheme ``ac_cv_func_$funcname``, ``ac_cv_lib_$library_$funcname``, or ``ac_cv_header_$headername_h``. ``SYS_SELECT_WITH_SYS_TIME`` is no longer used. ``uuid_create`` and ``uuid_enc_be`` are provided by libc on BSD. It is safe to use ``AC_CHECK_FUNCS`` here. Caching speeds up ./configure -C from ~ 4s to 2.6s on my system. Co-authored-by: Erlend Egeberg Aasland <erlend.aasland@innova.no>

* bpo-45522: Allow to disable freelists on build time (GH-29056)Christian Heimes2021-10-211-0/+3
| | | | | | | | Freelists for object structs can now be disabled. A new ``configure`` option ``--without-freelists`` can be used to disable all freelists except empty tuple singleton. Internal Py*_MAXFREELIST macros can now be defined as 0 without causing compiler warnings and segfaults. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-45440: Remove pymath.c fallbacks (GH-28977)Victor Stinner2021-10-151-9/+0
| | | | | | | | Remove fallbacks for missing round(), copysign() and hypot() in Python/pymath.c. Python now requires these functions to build. These fallbacks were needed on Visual Studio 2012 and older. They are no longer needed since Visual Stuido 2013. Python is now built with Visual Studio 2017 or newer since Python 3.6.
* bpo-45440: Require math.h isinf() to build (GH-28894)Victor Stinner2021-10-131-12/+0
| | | | | | | | | | | | | | | Building Python now requires a C99 <math.h> header file providing isinf(), isnan() and isfinite() functions. Remove the Py_FORCE_DOUBLE() macro. It was used by the Py_IS_INFINITY() macro. Changes: * Remove Py_IS_NAN(), Py_IS_INFINITY() and Py_IS_FINITE() in PC/pyconfig.h. * Remove the _Py_force_double() function. * configure no longer checks if math.h defines isinf(), isnan() and isfinite().
* bpo-29410: Change the default hash algorithm to SipHash13. (GH-28752)Inada Naoki2021-10-101-1/+1

* bpo-41710: PyThread_acquire_lock_timed() uses sem_clockwait() (GH-28662)Victor Stinner2021-10-011-3/+6
| | | | | | | | | On Unix, if the sem_clockwait() function is available in the C library (glibc 2.30 and newer), the threading.Lock.acquire() method now uses the monotonic clock (time.CLOCK_MONOTONIC) for the timeout, rather than using the system clock (time.CLOCK_REALTIME), to not be affected by system clock changes. configure now checks if the sem_clockwait() function is available.
* bpo-21302: Add nanosleep() implementation for time.sleep() in Unix (GH-28545)Victor Stinner2021-09-251-0/+3
| | | Co-authored-by: Livius <egyszeregy@freemail.hu>
* bpo-21302: Add clock_nanosleep() implementation for time.sleep() (GH-28111)Livius2021-09-131-0/+3
| | | | | | In Unix operating systems, time.sleep() now uses the clock_nanosleep() function, if available, which allows to sleep for an interval specified with nanosecond precision. Co-authored-by: Victor Stinner <vstinner@python.org>
