Stop rejecting IPv4 octets for being ambiguously octal. Leading zeros are
|

ignored, and no longer are assumed to specify octal octets. Octets are
|

always decimal numbers. Octets must still be no more than three digits,

including leading zeroes.

On Unix, C extensions are no longer linked to libpython except on Android
|
|
and Cygwin.
|
|
|
|
It is now possible for a statically linked Python to load a C extension
|
|
built using a shared library Python.
|
|
|
|
When Python is embedded, ``libpython`` must not be loaded with
|
|
``RTLD_LOCAL``, but ``RTLD_GLOBAL`` instead. Previously, using
|
|
``RTLD_LOCAL``, it was already not possible to load C extensions which were
|
|
not linked to ``libpython``, such as C extensions of the standard library
|
|
built by the ``*shared*`` section of ``Modules/Setup``.
|
|
|
|
distutils, python-config and python-config.py have been modified.

Add ``-fmax-type-align=8`` to CFLAGS when clang compiler is detected. The
|
|
pymalloc memory allocator aligns memory on 8 bytes. On x86-64, clang expects
|
|
alignment on 16 bytes by default and so uses MOVAPS instruction which can
|
|
lead to segmentation fault. Instruct clang that Python is limited to
|
|
alignment on 8 bytes to use MOVUPS instruction instead: slower but don't
|
|
trigger a SIGSEGV if the memory is not aligned on 16 bytes. Sadly, the flag
|
|
must be added to ``CFLAGS`` and not just ``CFLAGS_NODIST``, since third
|
|
party C extensions can have the same issue.

Release builds and debug builds are now ABI compatible: defining the

``Py_DEBUG`` macro no longer implies the ``Py_TRACE_REFS`` macro, which

|
|
environment variable, can be set using the new ``./configure
