* 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-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

* 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>

* bpo-43179: Generalise alignment for optimised string routines (GH-24624)Jessica Clarke2021-03-311-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | * Remove m68k-specific hack from ascii_decode On m68k, alignments of primitives is more relaxed, with 4-byte and 8-byte types only requiring 2-byte alignment, thus using sizeof(size_t) does not work. Instead, use the portable alternative. Note that this is a minimal fix that only relaxes the assertion and the condition for when to use the optimised version remains overly strict. Such issues will be fixed tree-wide in the next commit. NB: In C11 we could use _Alignof(size_t) instead, but for compatibility we use autoconf. * Optimise string routines for architectures with non-natural alignment C only requires that sizeof(x) is a multiple of alignof(x), not that the two are equal. Thus anywhere where we optimise based on alignment we should be using alignof(x) not sizeof(x). This is more annoying than it would be in C11 where we could just use _Alignof(x) (and alignof(x) in C++11), but since we still require only C99 we must plumb the information all the way from autoconf through the various typedefs and defines.
* bpo-13501: allow choosing between readline and libedit (GH-24189)Roland Hieber2021-02-091-1/+4
| | | | | | | | | | | | | | | | | | | | | | | In contrast to macOS, libedit is available as its own include file and library on Linux systems to prevent file name clashes. So if both libraries are available on the system, readline is currently chosen by default; and if only libedit is available, it is not found at all. This patch adds a way to link against libedit by adding the following arguments to configure: --with-readline link against libreadline (the default) --with-readline=editline link against libeditline --with-readline=no disable building the readline module --without-readline (same) The runtime detection of libedit vs. readline was already done in commit 7105319ada2e66365902 (2019-12-04, serge-sans-paille: "bpo-38634: Allow non-apple build to cope with libedit (GH-16986)").

* bpo-39465: Add pycore_atomic_funcs.h header (GH-20766)Victor Stinner2020-12-231-4/+4
| | | | | | Add pycore_atomic_funcs.h internal header file: similar to pycore_atomic.h but don't require to declare variables as atomic. Add _Py_atomic_size_get() and _Py_atomic_size_set() functions.
