Add auditing events to the :mod:`marshal` module, and stop raising
|
|
``code.__init__`` events for every unmarshalled code object. Directly
|
|
instantiated code objects will continue to raise an event, and audit event
|
|
handlers should inspect or collect the raw marshal data. This reduces a

|
significant performance overhead when loading from ``.pyc`` files.

The deallocator function of the :exc:`BaseException` type now uses the
|
|
trashcan mechanism to prevent stack overflow. For example, when a
|
|
:exc:`RecursionError` instance is raised, it can be linked to another
|
|
RecursionError through the ``__context__`` attribute or the
|
|
``__traceback__`` attribute, and then a chain of exceptions is created. When
|
|
the chain is destroyed, nested deallocator function calls can crash with a
|
|
stack overflow if the chain is too long compared to the available stack
|
|
memory. Patch by Victor Stinner.

When the interpreter renders an exception, its name now has a complete

qualname. Previously only the class name was concatenated to the module

name, which sometimes resulted in an incorrect full name being displayed.

List sorting now uses the merge-ordering strategy from Munro and Wild's
|
|
``powersort()``. Unlike the former strategy, this is provably near-optimal
|
|
in the entropy of the distribution of run lengths. Most uses of
|
|
``list.sort()`` probably won't see a significant time difference, but may
|
|
see significant improvements in cases where the former strategy was
|
|
exceptionally poor. However, as these are all fast linear-time
|
|
approximations to a problem that's inherently at best quadratic-time to
|
|
solve truly optimally, it's also possible to contrive cases where the former
|
|
strategy did better.

|
|
of at runtime. This reduces the overhead of handling cell and free
|
|
variables, especially in the case where a variable is both an argument and

|
cell variable.

In ``importlib.metadata``, restore compatibility in the result from
|
|
``Distribution.entry_points`` (``EntryPoints``) to honor expectations in
|
|
older implementations and issuing deprecation warnings for these cases: A.
|
|
``EntryPoints`` objects are once again mutable, allowing for ``sort()``
|
|
and other list-based mutation operations. Avoid deprecation warnings by
|
|
casting to a mutable sequence (e.g. ``list(dist.entry_points).sort()``).
|
|
B. ``EntryPoints`` results once again allow for access by index. To avoid
|
|
deprecation warnings, cast the result to a Sequence first (e.g.
|
|
``tuple(dist.entry_points)[0]``).

|
|
aggregates:
|
|
|
|
* It is now possible to pass strings with embedded null characters to UDFs
|
|
* Conversion failures now correctly raise :exc:`MemoryError`

AIX: ``Lib/_aix_support.get_platform()`` may fail in an AIX WPAR. The fileset
|
|
bos.rte appears to have a builddate in both LPAR and WPAR so this fileset is
|
|
queried rather than bos.mp64. To prevent a similar situation (no builddate
|
|
in ODM) a value (9988) sufficient for completing a build is provided. Patch
|
|
by M Felt.

:func:`zlib.compress` now accepts a wbits parameter which allows users to
|
|
compress data as a raw deflate block without zlib headers and trailers in
|
|
one go. Previously this required instantiating a ``zlib.compressobj``. It
|
|
also provides a faster alternative to ``gzip.compress`` when wbits=31 is
|
|
used.

The ``Py_TPFLAGS_HAVE_VERSION_TAG`` type flag now does nothing. The
|
|
``Py_TPFLAGS_HAVE_AM_SEND`` flag (which was added in 3.10) is removed. Both
|
|
were unnecessary because it is not possible to have type objects with the
|
|
relevant fields missing.

Remove 4 private trashcan C API functions which were only kept for the
|
|
backward compatibility of the stable ABI with Python 3.8 and older, since
|
|
the trashcan API was not usable with the limited C API on Python 3.8 and
|
|
older. The trashcan API was excluded from the limited C API in Python 3.9.
|
|
|
|
Removed functions:
|
|
|
|
* _PyTrash_deposit_object()
|
|
* _PyTrash_destroy_chain()
|
|
* _PyTrash_thread_deposit_object()
|
|
* _PyTrash_thread_destroy_chain()
|
|
|
|
The trashcan C API was never usable with the limited C API, since old
|
|
trashcan macros accessed directly :c:type:`PyThreadState` members like
|
|
``_tstate->trash_delete_nesting``, whereas the :c:type:`PyThreadState`
|
|
structure is opaque in the limited C API.
|
|
|
|
Exclude also the ``PyTrash_UNWIND_LEVEL`` constant from the C API.
