This is the - recommendation when only float and/or complex arguments were seen. - -- 'Ambiguous / operator (..., ...) at line N', line marked by '?': - - A / operator was found for which int or long as well as float or - complex arguments were seen. This is highly unlikely; if it occurs, - you may have to restructure the code to keep the classic semantics, - or maybe you don't care about the classic semantics. - -- 'No conclusive evidence on line N', line marked by '*': - - A / operator was found for which no warnings were seen. This could - be code that was never executed, or code that was only executed - with user-defined objects as arguments. You will have to - investigate further. Note that // can be overloaded separately from - /, using __floordiv__. True division can also be separately - overloaded, using __truediv__. Classic division should be the same - as either of those. (XXX should I add a warning for division on - user-defined objects, to disambiguate this case from code that was - never executed?) - -- 'Phantom ... warnings for line N', line marked by '*': - - A warning was seen for a line not containing a / operator. The most - likely cause is a warning about code executed by 'exec' or eval() - (see note below), or an indirect invocation of the / operator, for - example via the div() function in the operator module. It could - also be caused by a change to the file between the time the test - script was run to collect warnings and the time fixdiv was run. - -- 'More than one / operator in line N'; or - 'More than one / operator per statement in lines N-N': - - The scanner found more than one / operator on a single line, or in a - statement split across multiple lines. Because the warnings - framework doesn't (and can't) show the offset within the line, and - the code generator doesn't always give the correct line number for - operations in a multi-line statement, we can't be sure whether all - operators in the statement were executed.

It means that the tokenize module - reported a '/' operator but the line it returns didn't contain a '/' - character at the indicated position. - -- 'Bad warning for line N: XYZ', line marked by '*': - - This really shouldn't happen. It means that a 'classic XYZ - division' warning was read with XYZ being something other than - 'int', 'long', 'float', or 'complex'. - -Notes: - -- The augmented assignment operator /= is handled the same way as the - / operator. - -- This tool never looks at the // operator; no warnings are ever - generated for use of this operator. - -- This tool never looks at the / operator when a future division - statement is in effect; no warnings are generated in this case, and - because the tool only looks at files for which at least one classic - division warning was seen, it will never look at files containing a - future division statement. - -- Warnings may be issued for code not read from a file, but executed - using the exec() or eval() functions. These may have - in the filename position, in which case the fixdiv script - will attempt and fail to open a file named '' and issue a - warning about this failure; or these may be reported as 'Phantom' - warnings (see above).

-    This class encapsulates support for HTML Help. Node names,

-    accumulated until a call to finalize(). At that time, three
-    output files are created in the current directory:
-
-        `helpbase`.hhp  is a HTML Help Workshop project file.
-                        It contains various information, some of
-                        which I do not understand; I just copied
-                        the default project info from a fresh
-                        installation.
-        `helpbase`.hhc  is the Contents file for the project.
-        `helpbase`.hhk  is the Index file for the project.
-
-    When these files are used as input to HTML Help Workshop,
-    the resulting file will be named:
-
-        `helpbase`.chm
-
-    If none of the defaults in `helpbase`.hhp are changed,

Subject: [PATCH 16/66] Adjust stable ABI internal documentation (GH-96896)

I was perusing this file, and noticed that this part of the documentation is slightly out of date: the `struct` items in this TOML file currently contain `struct_abi_kind` members, which distinguish between the different types of ABI compatibility described in the comment.

I've updated the comment to reflect this.

Subject: [PATCH 17/66] gh-97670: Remove sys.getdxp() and analyze_dxp.py script
 (#97671)

Remove the sys.getdxp() function and the Tools/scripts/analyze_dxp.py
script. DXP stands for "dynamic execution pairs". They were related
to DYNAMIC_EXECUTION_PROFILE and DXPAIRS macros which have been
removed in Python 3.11. Python can now be built with "./configure
--enable-pystats" to gather statistics on Python opcodes.

-Some helper functions to analyze the output of sys.getdxp() (which is
-only available if Python was built with -DDYNAMIC_EXECUTION_PROFILE).
-These will tell you which opcodes have been executed most frequently
-in the current process, and, if Python was also built with -DDXPAIRS,
-will tell you which instruction _pairs_ were executed most frequently,
-which may help in choosing new instructions.
-
-If Python was built without -DDYNAMIC_EXECUTION_PROFILE, importing
-this module will raise a RuntimeError.
-
-If you're running a script you want to profile, a simple way to get
-the common pairs is:
-
-$ PYTHONPATH=$PYTHONPATH:/Tools/scripts \
-./python -i -O the_script.py --args
-...

-* Add raw datagram socket functions to the event loop:
-  :meth:`~asyncio.AbstractEventLoop.sock_sendto`,
-  :meth:`~asyncio.AbstractEventLoop.sock_recvfrom` and
-  :meth:`~asyncio.AbstractEventLoop.sock_recvfrom_into`.
-  (Contributed by Alex Grönholm in :issue:`46805`.)
-
-* Add :meth:`~asyncio.streams.StreamWriter.start_tls` method for upgrading
-  existing stream-based connections to TLS. (Contributed by Ian Good in
-  :issue:`34975`.)
-
-* Add :class:`~asyncio.Barrier` class to the synchronization primitives of
-  the asyncio library. (Contributed by Yves Duprat and Andrew Svetlov in
-  :gh:`87518`.)
-
-* Add :class:`~asyncio.TaskGroup` class,
+* Added the :class:`~asyncio.TaskGroup` class,
   an :ref:`asynchronous context manager `
   holding a group of tasks that will wait for all of them upon exit.
-  (Contributed by Yury Seliganov and others.)
+  For new code this is recommended over using
+  :func:`~asyncio.create_task` and :func:`~asyncio.gather` directly.
+  (Contributed by Yury Selivanov and others in :gh:`90908`.)
+
+* Added :func:`~asyncio.timeout`, an asynchronous context manager for
+  setting a timeout on asynchronous operations. For new code this is
+  recommended over using :func:`~asyncio.wait_for` directly.
+  (Contributed by Andrew Svetlov in :gh:`90927`.)
+
+* Added the :class:`~asyncio.Runner` class, which exposes the machinery
+  used by :func:`~asyncio.run`.
+  (Contributed by Andrew Svetlov in :gh:`91218`.)
+
+* Added the :class:`~asyncio.Barrier` class to the synchronization
+  primitives in the asyncio library, and the related
+  :exc:`~asyncio.BrokenBarrierError` exception.
+  (Contributed by Yves Duprat and Andrew Svetlov in :gh:`87518`.)
+
+* Added keyword argument *all_errors* to :meth:`asyncio.loop.create_connection`
+  so that multiple connection errors can be raised as an :exc:`ExceptionGroup`.
+
+* Added the :meth:`asyncio.StreamWriter.start_tls` method for
+  upgrading existing stream-based connections to TLS.

-   on Windows).  If *delete* is true (the default), the file is
-   deleted as soon as it is closed.

+.. function:: NamedTemporaryFile(mode='w+b', buffering=-1, encoding=None, newline=None, suffix=None, prefix=None, dir=None, delete=True, *, errors=None, delete_on_close=True)
+
+   This function operates exactly as :func:`TemporaryFile` does, except the
+   following differences:
+
+   * This function returns a file that is guaranteed to have a visible name in
+     the file system.
+   * To manage the named file, it extends the parameters of
+     :func:`TemporaryFile` with *delete* and *delete_on_close* parameters that
+     determine whether and how the named file should be automatically deleted.
+
+   The returned object is always a :term:`file-like object` whose :attr:`!file`
+   attribute is the underlying true file object. This :term:`file-like object`
+   can be used in a :keyword:`with` statement, just like a normal file.  The
+   name of the temporary file can be retrieved from the :attr:`name` attribute
+   of the returned file-like object. On Unix, unlike with the
+   :func:`TemporaryFile`, the directory entry does not get unlinked immediately
+   after the file creation.
+
+   If *delete* is true (the default) and *delete_on_close* is true (the
+   default), the file is deleted as soon as it is closed. If *delete* is true
+   and *delete_on_close* is false, the file is deleted on context manager exit
+   only, or else when the :term:`file-like object` is finalized. Deletion is not
+   always guaranteed in this case (see :meth:`object.__del__`). If *delete* is
+   false, the value of *delete_on_close* is ignored.
+
+   Therefore to use the name of the temporary file to reopen the file after
+   closing it, either make sure not to delete the file upon closure (set the
+   *delete* parameter to be false) or, in case the temporary file is created in
+   a :keyword:`with` statement, set the *delete_on_close* parameter to be false.
+   The latter approach is recommended as it provides assistance in automatic
+   cleaning of the temporary file upon the context manager exit.
+
+   Opening the temporary file again by its name while it is still open works as
+   follows:
+
+   * On POSIX the file can always be opened again.
+   * On Windows, make sure that at least one of the following conditions are
+     fulfilled:
+
+         * *delete* is false
+         * additional open shares delete access (e.g. by calling :func:`os.open`
+           with the flag ``O_TEMPORARY``)
+         * *delete* is true but *delete_on_close* is false. Note, that in this
+           case the additional opens that do not share delete access (e.g.
+           created via builtin :func:`open`) must be closed before exiting the
+           context manager, else the :func:`os.unlink` call on context manager
+           exit will fail with a :exc:`PermissionError`.
+
+   On Windows, if *delete_on_close* is false, and the file is created in a
+   directory for which the user lacks delete access, then the :func:`os.unlink`
+   call on exit of the context manager will fail with a :exc:`PermissionError`.
+   This cannot happen when *delete_on_close* is true because delete access is
+   requested by the open, which fails immediately if the requested access is not
+   granted.
 
    On POSIX (only), a process that is terminated abruptly with SIGKILL
    cannot automatically delete any NamedTemporaryFiles it created.

+Windows ``py.exe`` launcher improvements
+----------------------------------------
+
+The copy of the :ref:`launcher` included with Python 3.11 has been significantly
+updated. It now supports company/tag syntax as defined in :pep:`514` using the
+``-V:/`` argument instead of the limited ``-.``.
+This allows launching distributions other than ``PythonCore``,
+the one hosted on `python.org `_.
+
+When using ``-V:`` selectors, either company or tag can be omitted, but all
+installs will be searched. For example, ``-V:OtherPython/`` will select the
+"best" tag registered for ``OtherPython``, while ``-V:3.11`` or ``-V:/3.11``
+will select the "best" distribution with tag ``3.11``.
+
+When using the legacy ``-``, ``-.``,
+``--`` or ``-.-`` arguments,
+all existing behaviour should be preserved from past versions,
+and only releases from ``PythonCore`` will be selected.
+However, the ``-64`` suffix now implies "not 32-bit" (not necessarily x86-64),
+as there are multiple supported 64-bit platforms.
+32-bit runtimes are detected by checking the runtime's tag for a ``-32`` suffix.
+All releases of Python since 3.5 have included this in their 32-bit builds.

spaces inside the non-capturing group (such as `(?: )`). This patch

+Pass the correct ``contextvars.Context`` when a ``asyncio`` exception handler is called on behalf of a task or callback handle. This adds a new ``Task`` method, ``get_context``, and also a new ``Handle`` method with the same name. If this method is not found on a task object (perhaps because it is a third-party library that does not yet provide this method), the context prevailing at the time the exception handler is called is used.
