Cases of sorting using tuples as keys may now be significantly faster in
|
|
some cases. Patch by Tim Peters.
|
|
|
|
The order of the result may differ from earlier releases if the tuple
|
|
elements don't define a total ordering (see
|
|
:ref:`expressions-value-comparisons` for information on total ordering).
|
|
It's generally true that the result of sorting simply isn't well-defined in
|
|
the absence of a total ordering on list elements.

Frozen stdlib modules now have ``__file__`` to the .py file they would
|
|
otherwise be loaded from, if possible. For packages, ``__path__`` now has
|
|
the correct entry instead of being an empty list, which allows unfrozen
|
|
submodules to be imported. These are set only if the stdlib directory is
|
|
known when the runtime is initialized. Note that the file at ``__file__``
|
|
is not guaranteed to exist. None of this affects non-stdlib frozen modules
|
|
nor, for now, frozen modules imported using
|
|
``PyImport_ImportFrozenModule()``. Also, at the moment ``co_filename`` is
|
|
not updated for the module.

For frozen stdlib modules, record the original module name as

``module.__spec__.name`` then the module was defined as an alias in
|
|
Tools/scripts/freeze_modules.py. If it is ``None`` then the module comes
|
|
from a source file outside the stdlib.

been moved to the ``Include/cpython`` directory. Moreover, the ``eval.h``
