[3.13] gh-86726: Document the full public API of tkinter (GH-151579) (GH-151650) (GH-151653)
Replace the previously sparse reference documentation with full coverage of
the public API of the tkinter package, written from the Tcl/Tk manual pages,
the existing documentation and the module docstrings.
* Doc/library/tkinter.rst gains a "Reference" section documenting every public
class, method, function and constant of the core module -- the widgets, the
Misc, Wm, Pack, Place, Grid, XView and YView mix-ins, the Variable and image
classes, the module-level functions and the symbolic constants.
* Doc/library/tkinter.ttk.rst, dialog.rst, tkinter.font.rst and the other
module pages document their remaining classes, methods and functions.
The descriptions are Python-oriented (correct return types -- tuples rather
than Tcl lists, booleans, integers, None on cancellation, and so on) and were
checked against the Tcl/Tk 9.1 manual pages and the implementation.
versionadded, versionchanged and deprecated directives are added for the
public API, determined from the git history relative to Python 3.0: the
tkinter.ttk module (3.1); the Text, Wm, Menu and Misc methods exposing Tk 8.5
features (3.3); and the many later additions and behavior changes up to 3.15.
The Tk version required by features added after Tk 8.6 is noted as well. The
bundled Tcl/Tk version is updated to 9.0 and the manual-page links point at
the tcl9.0 reference.
* gh-86726: Adjust tkinter docs for the 3.14 backport

pack_content/place_content aliases, Text.search_all, the search

wm_attributes positional-argument deprecation to 3.13, and update the
bundled Tcl/Tk version to 8.6.

chown(-1, 0) succeeds and the assertion spuriously fails.

gh-143988: Fix re-entrant mutation crashes in socket sendmsg/recvmsg_into (#143987)
Fix crashes in socket.sendmsg() and socket.recvmsg_into() that could
occur if buffer sequences are mutated re-entrantly during argument
parsing via __buffer__ protocol callbacks.
The bug occurs because:
1. PySequence_Fast() returns the original list object when the input
is already a list (not a copy).
2. During iteration, PyObject_GetBuffer() triggers __buffer__
callbacks which may clear the list.
3. Subsequent iterations access invalid memory (heap OOB read).
The fix replaces PySequence_Fast() with PySequence_Tuple() which
always creates a new tuple, ensuring the sequence cannot be mutated
during iteration.
