Freeing a great many small objects could take time quadratic in the number
|
|
of arenas, due to using linear search to keep ``obmalloc.c``'s list of
|
|
usable arenas sorted by order of number of free memory pools. This is
|
|
accomplished without search now, leaving the worst-case time linear in the
|
|
number of arenas. For programs where this quite visibly matters (typically
|
|
with more than 100 thousand small objects alive simultaneously), this can
|
|
greatly reduce the time needed to release their memory.

Add a ``=`` feature f-strings for debugging. This can precede ``!s``,

``!r``, or ``!a``. It produces the text of the expression, followed by an
|
|
equal sign, followed by the repr of the value of the expression. So
|
|
``f'{3*9+15=}'`` would be equal to the string ``'3*9+15=42'``. If ``=`` is
|
|
specified, the default conversion is set to ``!r``, unless a format spec is
|
|
given, in which case the formatting behavior is unchanged, and __format__
|

will be used.

To embed Python into an application, a new ``--embed`` option must be passed
|
|
to ``python3-config --libs --embed`` to get ``-lpython3.8`` (link the
|
|
application to libpython). To support both 3.8 and older, try
|
|
``python3-config --libs --embed`` first and fallback to ``python3-config
|
|
--libs`` (without ``--embed``) if the previous command fails.
|
|
|
|
Add a pkg-config ``python-3.8-embed`` module to embed Python into an
|
|
application: ``pkg-config python-3.8-embed --libs`` includes
|
|
``-lpython3.8``. To support both 3.8 and older, try ``pkg-config
|
|
python-X.Y-embed --libs`` first and fallback to ``pkg-config python-X.Y
|
|
--libs`` (without ``--embed``) if the previous command fails (replace
|
|
``X.Y`` with the Python version).
|
|
|
|
On the other hand, ``pkg-config python3.8 --libs`` no longer contains
|
|
``-lpython3.8``. C extensions must not be linked to libpython (except on
|
|
Android, case handled by the script); this change is backward incompatible
|
|
on purpose.
