bpo-21478: Record calls to parent when autospecced objects are used as child with attach_mock (GH 14688)

* Clear name and parent of mock in autospecced objects used with attach_mock

* Add NEWS entry

* Fix reversed order of comparison

* Test child and standalone function calls

* Use a helper function extracting mock to avoid code duplication and refactor tests.

Minor whitespace, indentation, and quoting changes to improve internal consistency and appease linters (GH-14888)

Repeat the command line arguments most recently entered before so the user can edit them.

* Make internals private

* Finish making mu and sigma private

* Add missing __hash__() method

* Add blurb

The compiler warning was introduced in
59ad110d.

Move the Editors and IDE section out of the Unix section, to its own section.

Eliminate delay of up to 100ms and accompanying visual artifact.
Fix bug of never showing context when hide and show.

* Use __qualname__ instead of __name__ in enum exception messages.

A bug in MSVC UCRT version 17763.615 (which has been fixed in newer versions) is causing test failures in some strptime/strftime tests when the default code page is c65001. This change selectively skips the tests affected by this.

Add two indent spec methods from editor and Rstrip to existing file.
Tests are not added for indent methods because they need change
in lights of 3.x's prohibition on mixing tabs and spaces.

Before:
    
        >>> email.message_from_string('From: a@malicious.org@important.com', policy=email.policy.default)['from'].addresses
        (Address(display_name='', username='a', domain='malicious.org'),)
    
        >>> parseaddr('a@malicious.org@important.com')
        ('', 'a@malicious.org')
    
    After:
    
        >>> email.message_from_string('From: a@malicious.org@important.com', policy=email.policy.default)['from'].addresses
        (Address(display_name='', username='', domain=''),)
    
        >>> parseaddr('a@malicious.org@important.com')
        ('', 'a@')

This exception was caused because the input ended unexpectedly with only one
single quote instead of a pair with some value inside it.

* bpo-37461: Fix infinite loop in parsing of specially crafted email headers.

Some crafted email header would cause the get_parameter method to run in an
infinite loop causing a DoS attack surface when parsing those headers. This
patch fixes that by making sure the DQUOTE character is handled to prevent
going into an infinite loop.

Rename paragraph.py to format.py and add region formatting methods
from editor.py.  Add tests for the latter.

PyObject_Malloc() and PyObject_Free() inlines pymalloc_alloc and
pymalloc_free partially.
But when PGO is not used, compiler don't know where is the hot part
in pymalloc_alloc and pymalloc_free.

* Only create CodeContext instances for "real" editors windows, but
  not e.g. shell or output windows.
* Remove configuration update Tk event fired every second, by having
  the editor window ask its code context widget to update when
  necessary, i.e. upon font or highlighting updates.
* When code context isn't being shown, avoid having a Tk event fired
  every 100ms to check whether the code context needs to be updated.
* Use the editor window's getlineno() method where applicable.
* Update font of the code context widget before the main text widget

As far as I can tell, this infinite loop would be triggered if:

1. The value being folded contains a single word (no spaces) longer than
   max_line_length
2. The max_line_length is shorter than the encoding's name + 9
   characters.

* Remove a vague statement in documentation

* Remove another vague sentence

A sentence starting with "So it should be possible..." shouldn't be in the docs either.

* Include the removal of the previous line
Co-Authored-By: Kyle Stanley <aeros167@gmail.com>

* Remove an extra space

Replace backquotes with POSIXy command substitution in example.

make install no longer installs "wininst-*.exe" files used by
distutils bdist_wininst: bdist_wininst only works on Windows.

Add a brief note to indicate that any new required attributes must go through the PEP process.

Add a new field to the compiler structure that allows to be configured
so no bytecode is emitted. In this way is possible to detect errors by
walking the nodes while preserving optimizations.

bpo-37593: Swap the positions of posonlyargs and args in the constructor of ast.parameters nodes (GH-14778)



https://bugs.python.org/issue37593

bpo-15386, bpo-37473: test_import, regrtest and libregrtest no longer
import importlib as soon as possible, as the first import, "to test

It is tested by test_import.test_there_can_be_only_one().

The documentation says that the fp parameter to plistlib.load "should be a
readable and binary file object" but the docstring only mentions that it
should be readable. Similarly, plistlib.dump's docstring only mentions
"writable". This commit clarifies that fp should also be binary.
