What's New in Python 3.7.0 alpha 1?
|
||
===================================
|
||
|
||
*Release date: XXXX-XX-XX*
|
||
|
||
Core and Builtins
|
||
-----------------
|
||
|
||
- bpo-30814: Fixed a race condition when import a submodule from a package.
|
||
|
||
- bpo-30736: The internal unicodedata database has been upgraded to Unicode
|
||
10.0.
|
||
|
||
- bpo-30604: Move co_extra_freefuncs from per-thread to per-interpreter to
|
||
avoid crashes.
|
||
|
||
- bpo-30597: ``print`` now shows expected input in custom error message when
|
||
used as a Python 2 statement. Patch by Sanyam Khurana.
|
||
|
||
- bpo-30682: Removed a too-strict assertion that failed for certain f-strings,
|
||
such as eval("f'\\\n'") and eval("f'\\\r'").
|
||
|
||
- bpo-30501: The compiler now produces more optimal code for complex condition
|
||
expressions in the "if", "while" and "assert" statement, the "if" expression,
|
||
and generator expressions and comprehensions.
|
||
|
||
- bpo-28180: Implement PEP 538 (legacy C locale coercion). This means that when
|
||
a suitable coercion target locale is available, both the core interpreter and
|
||
locale-aware C extensions will assume the use of UTF-8 as the default text
|
||
encoding, rather than ASCII.
|
||
|
||
- bpo-30486: Allows setting cell values for __closure__. Patch by Lisa Roach.
|
||
|
||
- bpo-30537: itertools.islice now accepts integer-like objects (having
|
||
an __index__ method) as start, stop, and slice arguments
|
||
|
||
- bpo-25324: Tokens needed for parsing in Python moved to C. ``COMMENT``,
|
||
``NL`` and ``ENCODING``. This way the tokens and tok_names in the token
|
||
module don't get changed when you import the tokenize module.
|
||
|
||
- bpo-29104: Fixed parsing backslashes in f-strings.
|
||
|
||
- bpo-27945: Fixed various segfaults with dict when input collections are
|
||
mutated during searching, inserting or comparing. Based on patches by
|
||
Duane Griffin and Tim Mitchell.
|
||
|
||
- bpo-25794: Fixed type.__setattr__() and type.__delattr__() for
|
||
non-interned attribute names. Based on patch by Eryk Sun.
|
||
|
||
- bpo-30039: If a KeyboardInterrupt happens when the interpreter is in
|
||
the middle of resuming a chain of nested 'yield from' or 'await'
|
||
calls, it's now correctly delivered to the innermost frame.
|
||
|
||
- bpo-28974: ``object.__format__(x, '')`` is now equivalent to ``str(x)``
|
||
rather than ``format(str(self), '')``.
|
||
|
||
- bpo-30024: Circular imports involving absolute imports with binding
|
||
a submodule to a name are now supported.
|
||
|
||
- bpo-12414: sys.getsizeof() on a code object now returns the sizes
|
||
which includes the code struct and sizes of objects which it references.
|
||
Patch by Dong-hee Na.
|
||
|
||
- bpo-29839: len() now raises ValueError rather than OverflowError if
|
||
__len__() returned a large negative integer.
|
||
|
||
- bpo-11913: README.rst is now included in the list of distutils standard
|
||
READMEs and therefore included in source distributions.
|
||
|
||
- bpo-29914: Fixed default implementations of __reduce__ and __reduce_ex__().
|
||
object.__reduce__() no longer takes arguments, object.__reduce_ex__() now
|
||
requires one argument.
|
||
|
||
- bpo-29949: Fix memory usage regression of set and frozenset object.
|
||
|
||
- bpo-29935: Fixed error messages in the index() method of tuple, list and deque
|
||
when pass indices of wrong type.
|
||
|
||
- bpo-29816: Shift operation now has less opportunity to raise OverflowError.
|
||
ValueError always is raised rather than OverflowError for negative counts.
|
||
Shifting zero with non-negative count always returns zero.
|
||
|
||
- bpo-24821: Fixed the slowing down to 25 times in the searching of some
|
||
unlucky Unicode characters.
|
||
|
||
- bpo-29102: Add a unique ID to PyInterpreterState. This makes it easier
|
||
to identify each subinterpreter.
|
||
|
||
- bpo-29894: The deprecation warning is emitted if __complex__ returns an
|
||
instance of a strict subclass of complex. In a future versions of Python
|
||
this can be an error.
|
||
|
||
- bpo-29859: Show correct error messages when any of the pthread_* calls in
|
||
thread_pthread.h fails.
|
||
|
||
- bpo-29849: Fix a memory leak when an ImportError is raised during from import.
|
||
|
||
- bpo-28856: Fix an oversight that %b format for bytes should support objects
|
||
follow the buffer protocol.
|
||
|
||
- bpo-29723: The ``sys.path[0]`` initialization change for bpo-29139 caused a
|
||
regression by revealing an inconsistency in how sys.path is initialized when
|
||
executing ``__main__`` from a zipfile, directory, or other import location.
|
||
The interpreter now consistently avoids ever adding the import location's
|
||
parent directory to ``sys.path``, and ensures no other ``sys.path`` entries
|
||
are inadvertently modified when inserting the import location named on the
|
||
command line.
|
||
|
||
- bpo-29568: Escaped percent "%%" in the format string for classic string
|
||
formatting no longer allows any characters between two percents.
|
||
|
||
- bpo-29714: Fix a regression that bytes format may fail when containing zero
|
||
bytes inside.
|
||
|
||
- bpo-29695: bool(), float(), list() and tuple() no longer take keyword arguments.
|
||
The first argument of int() can now be passes only as positional argument.
|
||
|
||
- bpo-28893: Set correct __cause__ for errors about invalid awaitables
|
||
returned from __aiter__ and __anext__.
|
||
|
||
- bpo-28876: ``bool(range)`` works even if ``len(range)``
|
||
raises :exc:`OverflowError`.
|
||
|
||
- bpo-29683: Fixes to memory allocation in _PyCode_SetExtra. Patch by
|
||
Brian Coleman.
|
||
|
||
- bpo-29684: Fix minor regression of PyEval_CallObjectWithKeywords.
|
||
It should raise TypeError when kwargs is not a dict. But it might
|
||
cause segv when args=NULL and kwargs is not a dict.
|
||
|
||
- bpo-28598: Support __rmod__ for subclasses of str being called before
|
||
str.__mod__. Patch by Martijn Pieters.
|
||
|
||
- bpo-29607: Fix stack_effect computation for CALL_FUNCTION_EX.
|
||
Patch by Matthieu Dartiailh.
|
||
|
||
- bpo-29602: Fix incorrect handling of signed zeros in complex constructor for
|
||
complex subclasses and for inputs having a __complex__ method. Patch
|
||
by Serhiy Storchaka.
|
||
|
||
- bpo-29347: Fixed possibly dereferencing undefined pointers
|
||
when creating weakref objects.
|
||
|
||
- bpo-29463: Add ``docstring`` field to Module, ClassDef, FunctionDef,
|
||
and AsyncFunctionDef ast nodes. docstring is not first stmt in their body
|
||
anymore. It affects ``co_firstlineno`` and ``co_lnotab`` of code object
|
||
for module and class.
|
||
|
||
- bpo-29438: Fixed use-after-free problem in key sharing dict.
|
||
|
||
- bpo-29546: Set the 'path' and 'name' attribute on ImportError for ``from ... import ...``.
|
||
|
||
- bpo-29546: Improve from-import error message with location
|
||
|
||
- bpo-29478: If max_line_length=None is specified while using the Compat32 policy,
|
||
it is no longer ignored. Patch by Mircea Cosbuc.
|
||
|
||
- Issue #29319: Prevent RunMainFromImporter overwriting sys.path[0].
|
||
|
||
- Issue #29337: Fixed possible BytesWarning when compare the code objects.

|
||
whitespace, not only spaces. Patch by Robert Xiao.

||
|
||
- bpo-22257: Clean up interpreter startup (see PEP 432).
|
||
|
||
- Issue #26919: On Android, operating system data is now always encoded/decoded
|
||
to/from UTF-8, instead of the locale encoding to avoid inconsistencies with
|
||
os.fsencode() and os.fsdecode() which are already using UTF-8.
|
||
|
||
- Issue #28991: functools.lru_cache() was susceptible to an obscure reentrancy
|
||
bug triggerable by a monkey-patched len() function.
|

|
||
built with Py_DEBUG defined.
|
||
|
||
- Issue #23722: Rather than silently producing a class that doesn't support
|
||
zero-argument ``super()`` in methods, failing to pass the new
|
||
``__classcell__`` namespace entry up to ``type.__new__`` now results in a
|
||
``DeprecationWarning`` and a class that supports zero-argument ``super()``.
|
||
|
||
- Issue #28797: Modifying the class __dict__ inside the __set_name__ method of
|
||
a descriptor that is used inside that class no longer prevents calling the
|

__set_name__ method of other descriptors.
|
||
|
||
- Issue #28799: Remove the ``PyEval_GetCallStats()`` function and deprecate
|
||
the untested and undocumented ``sys.callstats()`` function. Remove the
|
||
``CALL_PROFILE`` special build: use the :func:`sys.setprofile` function,
|
||
:mod:`cProfile` or :mod:`profile` to profile function calls.
|
||
|
||
- Issue #12844: More than 255 arguments can now be passed to a function.

- Issue #28774: Fix error position of the unicode error in ASCII and Latin1
|
||
encoders when a string returned by the error handler contains multiple
|
||
non-encodable characters (non-ASCII for the ASCII codec, characters out
|
||
of the U+0000-U+00FF range for Latin1).
|

|
||
- Issue #28731: Optimize _PyDict_NewPresized() to create correct size dict.

|
||
|
||
- Issue #27100: The with-statement now checks for __enter__ before it

Extension Modules
|
||
-----------------
|
||
|
||
- Issue #29169: Update zlib to 1.2.11.
|
||
|
||
Library
|
||
-------
|
||
|
||
- bpo-30879: os.listdir() and os.scandir() now emit bytes names when called
|
||
with bytes-like argument.
|
||
|
||
- bpo-30746: Prohibited the '=' character in environment variable names in
|
||
``os.putenv()`` and ``os.spawn*()``.
|
||
|
||
- bpo-30664: The description of a unittest subtest now preserves the order of
|
||
keyword arguments of TestCase.subTest().
|
||
|
||
- [Security] bpo-30730: Prevent environment variables injection in subprocess on
|
||
Windows. Prevent passing other environment variables and command arguments.
|
||
|
||
- bpo-21071: struct.Struct.format type is now :class:`str` instead of
|
||
:class:`bytes`.
|
||
|
||
- bpo-29212: Fix concurrent.futures.thread.ThreadPoolExecutor threads to have
|
||
a non repr() based thread name by default when no thread_name_prefix is
|
||
supplied. They will now identify themselves as "ThreadPoolExecutor-y_n".
|
||
|
||
- [Security] bpo-30694: Upgrade expat copy from 2.2.0 to 2.2.1 to get fixes
|
||
of multiple security vulnerabilities including: CVE-2017-9233 (External

||
entity infinite loop DoS), CVE-2016-9063 (Integer overflow, re-fix),
|
||
CVE-2016-0718 (Fix regression bugs from 2.2.0's fix to CVE-2016-0718)
|
||
and CVE-2012-0876 (Counter hash flooding with SipHash).
|
||
Note: the CVE-2016-5300 (Use os-specific entropy sources like getrandom)
|
||
doesn't impact Python, since Python already gets entropy from the OS to set
|
||
the expat secret using ``XML_SetHashSalt()``.
|
||
|
||
- bpo-29755: Fixed the lgettext() family of functions in the gettext module.
|
||
They now always return bytes.
|

||
- [Security] bpo-30500: Fix urllib.parse.splithost() to correctly parse
|
||
fragments. For example, ``splithost('//127.0.0.1#@evil.com/')`` now
|
||
correctly returns the ``127.0.0.1`` host, instead of treating ``@evil.com``
|
||
as the host in an authentification (``login@host``).
|
||
|
||
- bpo-30616: Functional API of enum allows to create empty enums.

|
||
code objects.
|

|
||
value for Python and C and will help in converting to `bool` in future.

|
||
Grzywacz.
|
||
|
||
- bpo-30197: Enhanced functions swap_attr() and swap_item() in the
|
||
test.support module. They now work when delete replaced attribute or item

|
||
-----------------
|
||
|
||
- Issue #23722: The __class__ cell used by zero-argument super() is now
|
||

||
during class creation. Patch by Martin Teichmann.

||
|
||

||
Patch by Jason Fried.

||

|
||
alpha releases, where backslashes are allowed anywhere in an

||
f-string. Also, require that expressions inside f-strings be
|
||
enclosed within literal braces, and not escapes like

||
``f'\x7b"hi"\x7d'``.

|
||
compiled without ``long long`` for years, so this is basically a formality.
|

|

|

and Windows CE is no longer a relevant platform for Python.
|

|
||
``int`` subclasses now always returns an ``int``. Previously
|

the return type depended on the input values. Patch by Xiang Zhang.
|
||
|
||
- Issue #26984: int() now always returns an instance of exact int.
|
||
|
||
- Issue #25604: Fix a minor bug in integer true division; this bug could
|

||
by a contextlib.ExitStack() and one of the exit stack generators
|

when exiting, let the new chained one through. This avoids the PEP 479
|
||
bug described in issue25782.
|
||
|
||
- [Security] Issue #27278: Fix os.urandom() implementation using getrandom() on

|
||
===================================
|
||
|
||
Release date: 2016-05-16
|
||
|
||
Core and Builtins
|
||
-----------------
|
||
|
||
- Issue #20041: Fixed TypeError when frame.f_trace is set to None.
|
||
Patch by Xavier de Gaye.
|
||
|
||
- Issue #26168: Fixed possible refleaks in failing Py_BuildValue() with the "N"
|
||
format unit.
|
||
|
||
- Issue #26991: Fix possible refleak when creating a function with annotations.
|
||
|
||
- Issue #27039: Fixed bytearray.remove() for values greater than 127. Based on
|
||
patch by Joe Jevnik.
|
||
|
||
- Issue #23640: int.from_bytes() no longer bypasses constructors for subclasses.
|
||
|
||
- Issue #27005: Optimized the float.fromhex() class method for exact float.
|
||
It is now 2 times faster.
|
||
|
||
- Issue #18531: Single var-keyword argument of dict subtype was passed
|
||
unscathed to the C-defined function. Now it is converted to exact dict.
|
||
|
||
- Issue #26811: gc.get_objects() no longer contains a broken tuple with NULL
|
||
pointer.
|
||
|
||
- Issue #20120: Use RawConfigParser for .pypirc parsing,
|
||
removing support for interpolation unintentionally added
|
||
with move to Python 3. Behavior no longer does any
|
||
interpolation in .pypirc files, matching behavior in Python
|
||
2.7 and Setuptools 19.0.
|
||
|
||
- Issue #26249: Memory functions of the :c:func:`PyMem_Malloc` domain
|
||
(:c:data:`PYMEM_DOMAIN_MEM`) now use the :ref:`pymalloc allocator <pymalloc>`
|
||
rather than system :c:func:`malloc`. Applications calling
|
||
:c:func:`PyMem_Malloc` without holding the GIL can now crash: use
|
||
``PYTHONMALLOC=debug`` environment variable to validate the usage of memory
|
||
allocators in your application.
|
||
|
||
- Issue #26802: Optimize function calls only using unpacking like
|
||
``func(*tuple)`` (no other positional argument, no keyword): avoid copying

|
||
|
||
- Issue #26659: Make the builtin slice type support cycle collection.
|
||
|
||

|
||
error handler for stdin and stdout.
|
||
|
||
- Issue #26494: Fixed crash on iterating exhausting iterators.
|
||
Affected classes are generic sequence iterators, iterators of str, bytes,
|
||
bytearray, list, tuple, set, frozenset, dict, OrderedDict, corresponding
|
||
views and os.scandir() iterator.
|
||
|
||
- Issue #26574: Optimize ``bytes.replace(b'', b'.')`` and
|
||
``bytearray.replace(b'', b'.')``. Patch written by Josh Snider.
|
||
|
||
- Issue #26581: If coding cookie is specified multiple times on a line in
|
||
Python source code file, only the first one is taken to account.
|
||
|
||

|
||
|
||
- Issue #26563: Debug hooks on Python memory allocators now raise a fatal
|
||
error if functions of the :c:func:`PyMem_Malloc` family are called without
|
||
holding the GIL.
|
||
|
||
- Issue #26564: On error, the debug hooks on Python memory allocators now use
|
||
the :mod:`tracemalloc` module to get the traceback where a memory block was
|
||
allocated.
|
||
|
||
- Issue #26558: The debug hooks on Python memory allocator
|
||
:c:func:`PyObject_Malloc` now detect when functions are called without
|
||
holding the GIL.
|
||
|
||
- Issue #26516: Add :envvar:`PYTHONMALLOC` environment variable to set the
|
||
Python memory allocators and/or install debug hooks.
|
||
|
||
- Issue #26516: The :c:func:`PyMem_SetupDebugHooks` function can now also be
|
||
used on Python compiled in release mode.
|
||
|
||
- Issue #26516: The :envvar:`PYTHONMALLOCSTATS` environment variable can now
|
||
also be used on Python compiled in release mode. It now has no effect if
|
||
set to an empty string.
|
||
|
||
- Issue #26516: In debug mode, debug hooks are now also installed on Python
|
||
memory allocators when Python is configured without pymalloc.
|
||
|
||
- Issue #26464: Fix str.translate() when string is ASCII and first replacements
|
||
removes character, but next replacement uses a non-ASCII character or a
|
||
string longer than 1 character. Regression introduced in Python 3.5.0.
|
||
|
||
- Issue #22836: Ensure exception reports from PyErr_Display() and
|
||
PyErr_WriteUnraisable() are sensible even when formatting them produces
|
||
secondary errors. This affects the reports produced by
|
||
sys.__excepthook__() and when __del__() raises an exception.
|
||
|
||
- Issue #26302: Correct behavior to reject comma as a legal character for
|
||
cookie names.
|
||
|
||
- Issue #26136: Upgrade the warning when a generator raises StopIteration
|
||
from PendingDeprecationWarning to DeprecationWarning. Patch by Anish
|
||
Shah.
|
||
|
||
- Issue #26204: The compiler now ignores all constant statements: bytes, str,
|
||
int, float, complex, name constants (None, False, True), Ellipsis
|
||
and ast.Constant; not only str and int. For example, ``1.0`` is now ignored
|
||
in ``def f(): 1.0``.
|
||
|
||
- Issue #4806: Avoid masking the original TypeError exception when using star
|
||
(``*``) unpacking in function calls. Based on patch by Hagen Fürstenau and
|
||
Daniel Urban.
|
||
|
||
- Issue #26146: Add a new kind of AST node: ``ast.Constant``. It can be used
|
||
by external AST optimizers, but the compiler does not emit directly such
|
||
node.
|
||
|
||
- Issue #23601: Sped-up allocation of dict key objects by using Python's
|
||
small object allocator. (Contributed by Julian Taylor.)

||
import is attempted without a known parent package.
|
||
|
||
- Issue #25843: When compiling code, don't merge constants if they are equal
|
||
but have a different types. For example, ``f1, f2 = lambda: 1, lambda: 1.0``
|
||
is now correctly compiled to two different functions: ``f1()`` returns ``1``
|
||
(``int``) and ``f2()`` returns ``1.0`` (``float``), even if ``1`` and ``1.0``
|
||
are equal.
|
||
|
||
- Issue #26107: The format of the ``co_lnotab`` attribute of code objects
|
||
changes to support negative line number delta.
|
||
|
||
- Issue #26154: Add a new private _PyThreadState_UncheckedGet() function to get
|
||
the current Python thread state, but don't issue a fatal error if it is NULL.
|
||
This new function must be used instead of accessing directly the
|
||
_PyThreadState_Current variable. The variable is no more exposed since
|
||
Python 3.5.1 to hide the exact implementation of atomic C types, to avoid
|
||
compiler issues.
|
||
|
||
- Issue #25791: If __package__ != __spec__.parent or if neither __package__ or
|
||
__spec__ are defined then ImportWarning is raised.
|
||
|
||

|
||
subclasses of list or dict and haven't implemented any pickle-related
|
||
methods (__reduce__, __reduce_ex__, __getnewargs__, __getnewargs_ex__,
|
||
or __getstate__), can no longer be pickled. Including memoryview.
|
||
|
||
- Issue #20440: Massive replacing unsafe attribute setting code with special
|
||
macro Py_SETREF.
|
||
|
||
- Issue #25766: Special method __bytes__() now works in str subclasses.
|
||
|
||
- Issue #25421: __sizeof__ methods of builtin types now use dynamic basic size.
|
||
This allows sys.getsize() to work correctly with their subclasses with
|
||
__slots__ defined.
|
||
|
||
- Issue #25709: Fixed problem with in-place string concatenation and utf-8
|

|
||
|
||
- Issue #24097: Fixed crash in object.__reduce__() if slot name is freed inside
|
||
__getattr__.

||
|
||
- Issue #24731: Fixed crash on converting objects with special methods
|

that accept filesystem paths.
|
||
|
||
- Issue #23564: Fixed a partially broken sanity check in the _posixsubprocess
|
||
internals regarding how fds_to_pass were passed to the child. The bug had
|
||
no actual impact as subprocess.py already avoided it.
|
||
|
||
- Issue #25388: Fixed tokenizer crash when processing undecodable source code
|
||
with a null byte.
|
||
|
||

|
||
operations in C implementation of OrderedDict.
|

|
||
rejects builtin types with not defined __new__.
|
||
|
||
- Issue #24802: Avoid buffer overreads when int(), float(), compile(), exec()
|
||
and eval() are passed bytes-like objects. These objects are not
|
||
necessarily terminated by a null byte, but the functions assumed they were.

||
|
||

|
||
API. Formatting is now between 2.5 and 5 times faster.
|
||
|
||
- Issue #25274: sys.setrecursionlimit() now raises a RecursionError if the new
|
||
recursion limit is too low depending at the current recursion depth. Modify
|
||
also the "lower-water mark" formula to make it monotonic. This mark is used
|
||
to decide when the overflowed flag of the thread state is reset.

||
error handler: the encoders are now up to 3 times as fast. Initial patch
|
||
written by Serhiy Storchaka.
|
||
|
||
- Issue #25003: On Solaris 11.3 or newer, os.urandom() now uses the

- Issue #25873: Optimized iterating ElementTree. Iterating elements

||
|
||
- Issue #25902: Fixed various refcount issues in ElementTree iteration.
|
||
|

- Issue #25761: Improved detecting errors in broken pickle data.
|
||
|
||
- Issue #25717: Restore the previous behaviour of tolerating most fstat()
|
||
errors when opening files. This was a regression in 3.5a1, and stopped
|
||
anonymous temporary files from working in special cases.
|
||
|
||
- Issue #24903: Fix regression in number of arguments compileall accepts when
|
||
'-d' is specified. The check on the number of arguments has been dropped
|

||
|
||
- Issue #25764: In the subprocess module, preserve any exception caused by
|
||
fork() failure when preexec_fn is used.

with time.tzset().
|
||
|
||
- Issue #14285: When executing a package with the "python -m package" option,
|
||
and package initialization fails, a proper traceback is now reported. The
|
||
"runpy" module now lets exceptions from package initialization pass back to
|
||
the caller, rather than raising ImportError.
|
||
|
||
- Issue #19771: Also in runpy and the "-m" option, omit the irrelevant
|
||
message ". . . is a package and cannot be directly executed" if the package
|
||
could not even be initialized (e.g. due to a bad ``*.pyc`` file).
|
||
|
||
- Issue #25177: Fixed problem with the mean of very small and very large

||
- Issue #25624: ZipFile now always writes a ZIP_STORED header for directory
|
||
entries. Patch by Dingyuan Wang.
|
||
|
||
- Issue #25626: Change three zlib functions to accept sizes that fit in
|
||
Py_ssize_t, but internally cap those sizes to UINT_MAX. This resolves a
|
||
regression in 3.5 where GzipFile.read() failed to read chunks larger than 2
|
||
or 4 GiB. The change affects the zlib.Decompress.decompress() max_length
|
||
parameter, the zlib.decompress() bufsize parameter, and the
|
||
zlib.Decompress.flush() length parameter.

not allow the send_signal(), terminate(), or kill() methods to do
|
||
anything as they could potentially signal a different process.
|
||
|
||

|
||
for the following modules: calendar, csv, enum, fileinput, ftplib, logging,

test.support.check__all__() helper. Patches by Jacek Kołodziej, Mauro
|
||
S. M. Rodrigues and Joel Taddei.
|
||
|
||
- Issue #25590: In the Readline completer, only call getattr() once per

IDLE
|

----
|
||
|
||

|
||
Patch by Saimadhav Heblikar.
|
||
|
||
- In the 'IDLE-console differences' section of the IDLE doc, clarify
|
||
how running with IDLE affects sys.modules and the standard streams.

|
||
|
||
- Issue #15348: Stop the debugger engine (normally in a user process)
|
||
before closing the debugger window (running in the IDLE process).
|
||
This prevents the RuntimeErrors that were being caught and ignored.
|
||
|
||
- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
|
||
debugger is active (15347); b) closing the debugger with the [X] button
|
||
(15348); and c) activating the debugger when already active (24455).
|
||
The patch by Mark Roseman does this by making two changes.
|
||
1. Suspend and resume the gui.interaction method with the tcl vwait
|
||
mechanism intended for this purpose (instead of root.mainloop & .quit).
|
||
2. In gui.run, allow any existing interaction to terminate first.
|
||
|
||
- Change 'The program' to 'Your program' in an IDLE 'kill program?' message
|
||
to make it clearer that the program referred to is the currently running
|
||
user program, not IDLE itself.
|
||
|
||

||
- Issue #22726: Re-activate the config dialog help button with some content
|
||
about the other buttons and the new IDLE Dark theme.
|
||
|
||
- Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
|
||
It is more or less IDLE Classic inverted, with a cobalt blue background.
|
||
Strings, comments, keywords, ... are still green, red, orange, ... .
|
||
To use it with IDLEs released before November 2015, hit the
|
||
'Save as New Custom Theme' button and enter a new name,
|
||
such as 'Custom Dark'. The custom theme will work with any IDLE
|
||
release, and can be modified.
|
||
|
||
- Issue #25224: README.txt is now an idlelib index for IDLE developers and
|
||

|
||
|
||
- Issue #25198: Enhance the initial html viewer now used for Idle Help.
|
||
* Properly indent fixed-pitch text (patch by Mark Roseman).
|
||
* Give code snippet a very Sphinx-like light blueish-gray background.
|
||
* Re-use initial width and height set by users for shell and editor.

Use idleib.idle.* to start Idle. See idlelib.__init__.__doc__.
|
||
|
||
- Issue #25199: Idle: add synchronization comments for future maintainers.
|
||
|
||
- Issue #16893: Replace help.txt with help.html for Idle doc display.
|
||
The new idlelib/help.html is rstripped Doc/build/html/library/idle.html.
|
||
It looks better than help.txt and will better document Idle as released.
|
||
The tkinter html viewer that works for this file was written by Rose Roseman.
|
||
The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated.
|
||
|

|
||
pointer.
|
||
|
||
- Issue #20120: Use RawConfigParser for .pypirc parsing,
|
||
removing support for interpolation unintentionally added
|
||
with move to Python 3. Behavior no longer does any
|
||
interpolation in .pypirc files, matching behavior in Python
|
||
2.7 and Setuptools 19.0.
|
||
|
||
- Issue #26659: Make the builtin slice type support cycle collection.
|
||
|

|
||
NOTE: A direct call of super.__init__ is not endorsed!

|
||
error handler for stdin and stdout.

|
||
|
||
- Issue #22836: Ensure exception reports from PyErr_Display() and

|
||

|
||
the current Python thread state, but don't issue a fatal error if it is NULL.
|
||
This new function must be used instead of accessing directly the
|
||
_PyThreadState_Current variable. The variable is no more exposed since
|
||
Python 3.5.1 to hide the exact implementation of atomic C types, to avoid
|
||
compiler issues.
|
||
|
||
- Issue #26194: Deque.insert() gave odd results for bounded deques that had
|
||
reached their maximum size. Now an IndexError will be raised when attempting
|
||
to insert into a full deque.
|
||
|
||
- Issue #25843: When compiling code, don't merge constants if they are equal
|
||
but have a different types. For example, ``f1, f2 = lambda: 1, lambda: 1.0``
|
||
is now correctly compiled to two different functions: ``f1()`` returns ``1``
|
||
(``int``) and ``f2()`` returns ``1.0`` (``int``), even if ``1`` and ``1.0``
|
||
are equal.

||
starting with two underscores.
|
||
|
||

|
||
subclasses of list or dict and haven't implemented any pickle-related
|
||
methods (__reduce__, __reduce_ex__, __getnewargs__, __getnewargs_ex__,
|
||
or __getstate__), can no longer be pickled. Including memoryview.
|
||
|
||
- Issue #20440: Massive replacing unsafe attribute setting code with special
|
||
macro Py_SETREF.
|
||
|
||
- Issue #25766: Special method __bytes__() now works in str subclasses.
|
||
|
||
- Issue #25421: __sizeof__ methods of builtin types now use dynamic basic size.
|
||
This allows sys.getsize() to work correctly with their subclasses with
|
||
__slots__ defined.
|
||
|
||
- Issue #25709: Fixed problem with in-place string concatenation and utf-8
|

__bytes__, __trunc__, and __float__ returning instances of subclasses of
|
||
bytes, int, and float to subclasses of bytes, int, and float correspondingly.
|
||
|
||
- Issue #26478: Fix semantic bugs when using binary operators with dictionary
|
||
views and tuples.
|
||
|
||
- Issue #26171: Fix possible integer overflow and heap corruption in
|
||
zipimporter.get_data().

|
||
Patch by Xavier de Gaye.
|
||
|
||
- Issue #22359: Disable the rules for running _freeze_importlib and pgen when

Some compilers and toolchains are known to not produce stable code when
|
||
using LTO, be sure to test things thoroughly before relying on it.
|
||
It can provide a few % speed up over profile-opt alone.

What's New in Python 3.5.1 release candidate 1?
|
||
===============================================
|
||
|
||
Release date: 2015-11-22
|
||
|
||
Core and Builtins
|
||
-----------------
|
||
|
||
- Issue #25630: Fix a possible segfault during argument parsing in functions
|
||
that accept filesystem paths.
|
||
|
||
- Issue #23564: Fixed a partially broken sanity check in the _posixsubprocess
|
||
internals regarding how fds_to_pass were passed to the child. The bug had
|
||
no actual impact as subprocess.py already avoided it.
|
||
|
||
- Issue #25388: Fixed tokenizer crash when processing undecodable source code
|
||
with a null byte.
|
||
|
||
- Issue #25462: The hash of the key now is calculated only once in most
|
||
operations in C implementation of OrderedDict.
|
||
|
||
- Issue #22995: Default implementation of __reduce__ and __reduce_ex__ now
|
||
rejects builtin types with not defined __new__.
|
||
|
||
- Issue #25555: Fix parser and AST: fill lineno and col_offset of "arg" node
|
||
when compiling AST from Python objects.
|
||
|
||
- Issue #24802: Avoid buffer overreads when int(), float(), compile(), exec()
|
||
and eval() are passed bytes-like objects. These objects are not
|
||
necessarily terminated by a null byte, but the functions assumed they were.
|
||
|
||
- Issue #24726: Fixed a crash and leaking NULL in repr() of OrderedDict that
|
||
was mutated by direct calls of dict methods.
|
||
|
||
- Issue #25449: Iterating OrderedDict with keys with unstable hash now raises
|
||
KeyError in C implementations as well as in Python implementation.
|
||
|
||
- Issue #25395: Fixed crash when highly nested OrderedDict structures were
|
||
garbage collected.
|
||
|
||
- Issue #25274: sys.setrecursionlimit() now raises a RecursionError if the new
|
||
recursion limit is too low depending at the current recursion depth. Modify
|
||
also the "lower-water mark" formula to make it monotonic. This mark is used
|
||
to decide when the overflowed flag of the thread state is reset.
|
||
|
||
- Issue #24402: Fix input() to prompt to the redirected stdout when
|
||
sys.stdout.fileno() fails.
|
||
|
||
- Issue #24806: Prevent builtin types that are not allowed to be subclassed from
|
||
being subclassed through multiple inheritance.
|
||
|
||
- Issue #24848: Fixed a number of bugs in UTF-7 decoding of misformed data.
|
||
|
||
- Issue #25280: Import trace messages emitted in verbose (-v) mode are no
|
||
longer formatted twice.
|
||
|
||
- Issue #25003: On Solaris 11.3 or newer, os.urandom() now uses the
|
||
getrandom() function instead of the getentropy() function. The getentropy()
|
||
function is blocking to generate very good quality entropy, os.urandom()
|
||
doesn't need such high-quality entropy.
|
||
|
||
- Issue #25182: The stdprinter (used as sys.stderr before the io module is
|
||
imported at startup) now uses the backslashreplace error handler.
|
||
|
||
- Issue #25131: Make the line number and column offset of set/dict literals and
|
||
comprehensions correspond to the opening brace.
|
||
|
||
- Issue #25150: Hide the private _Py_atomic_xxx symbols from the public
|
||
Python.h header to fix a compilation error with OpenMP. PyThreadState_GET()
|
||
becomes an alias to PyThreadState_Get() to avoid ABI incompatibilies.
|
||
|
||
Library
|
||
-------
|
||
|
||
- Issue #25626: Change three zlib functions to accept sizes that fit in
|
||
Py_ssize_t, but internally cap those sizes to UINT_MAX. This resolves a
|
||
regression in 3.5 where GzipFile.read() failed to read chunks larger than 2
|
||
or 4 GiB. The change affects the zlib.Decompress.decompress() max_length
|
||
parameter, the zlib.decompress() bufsize parameter, and the
|
||
zlib.Decompress.flush() length parameter.
|
||
|

anything as they could potentially signal a different process.
|
||
|
||
- Issue #25590: In the Readline completer, only call getattr() once per
|
||
attribute.
|
||
|
||

||
on patch by Eryksun.
|
||
|
||
- Issue #25584: Added "escape" to the __all__ list in the glob module.

|
||
|
||
- Issue #25441: asyncio: Raise error from drain() when socket is closed.
|
||
|
||

|
||
Python 3.6.
|
||
|

|
||
pickletools.opcodes.
|
||
|
||
- Issue #23972: Updates asyncio datagram create method allowing reuseport
|
||
and reuseaddr socket options to be set prior to binding the socket.
|
||
Mirroring the existing asyncio create_server method the reuseaddr option
|
||
for datagram sockets defaults to True if the O/S is 'posix' (except if the
|
||
platform is Cygwin). Patch by Chris Laws.
|
||
|
||
- Issue #25304: Add asyncio.run_coroutine_threadsafe(). This lets you
|
||
submit a coroutine to a loop from another thread, returning a
|
||
concurrent.futures.Future. By Vincent Michel.
|
||
|
||
- Issue #25232: Fix CGIRequestHandler to split the query from the URL at the
|
||
first question mark (?) rather than the last. Patch from Xiang Zhang.

|
||
query part of the URL as if it were a path. Patch from Xiang Zhang.
|
||

|
||
hash only once.

|
||
opcodes no longer silently ignored on 32-bit platforms in C implementation.
|
||
|
||
- Issue #25034: Fix string.Formatter problem with auto-numbering and
|
||
nested format_specs. Patch by Anthon van der Neut.
|
||
|
||
- Issue #25233: Rewrite the guts of asyncio.Queue and
|
||
asyncio.Semaphore to be more understandable and correct.
|
||
|
||
- Issue #25203: Failed readline.set_completer_delims() no longer left the
|
||
module in inconsistent state.
|
||
|
||

|
||

|
||
|

|
||
LibreSSL.
|

||
- Prevent overflow in _Unpickler_Read.

|
||
EINVAL.
|
||
|
||
- Issue #23517: Fix rounding in fromtimestamp() and utcfromtimestamp() methods
|
||
of datetime.datetime: microseconds are now rounded to nearest with ties
|
||
going to nearest even integer (ROUND_HALF_EVEN), instead of being rounding
|
||
towards minus infinity (ROUND_FLOOR). It's important that these methods use
|
||
the same rounding mode than datetime.timedelta to keep the property:
|
||
(datetime(1970,1,1) + timedelta(seconds=t)) == datetime.utcfromtimestamp(t).
|
||
It also the rounding mode used by round(float) for example.
|
||
|
||
- Issue #25155: Fix datetime.datetime.now() and datetime.datetime.utcnow() on

Windows to support date after year 2038. It was a regression introduced in
|
||
Python 3.5.0.

||
- Issue #25118: Fix a regression of Python 3.5.0 in os.waitpid() on Windows.
|
||
|
||
- Issue #24684: socket.socket.getaddrinfo() now calls
|
||
PyUnicode_AsEncodedString() instead of calling the encode() method of the
|
||
host, to handle correctly custom string with an encode() method which doesn't
|
||
return a byte string. The encoder of the IDNA codec is now called directly
|
||
instead of calling the encode() method of the string.
|
||
|
||
- Issue #25060: Correctly compute stack usage of the BUILD_MAP opcode.
|
||
|
||
- Issue #24857: Comparing call_args to a long sequence now correctly returns a
|
||

|
||
of stdin (0), stdout (1) or stderr (2) is closed while Python is creating
|
||
sys.stdin, sys.stdout and sys.stderr objects. These attributes are now set
|
||
to None if the creation of the object failed, instead of raising an OSError
|
||
exception. Initial patch written by Marco Paolini.
|
||
|
||
- Issue #24992: Fix error handling and a race condition (related to garbage
|
||
collection) in collections.OrderedDict constructor.
|
||
|
||
- Issue #24881: Fixed setting binary mode in Python implementation of FileIO
|

|
||
IDLE
|
||
----
|
||
|
||
- Issue #15348: Stop the debugger engine (normally in a user process)
|
||
before closing the debugger window (running in the IDLE process).
|
||
This prevents the RuntimeErrors that were being caught and ignored.
|
||
|
||
- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
|
||
debugger is active (15347); b) closing the debugger with the [X] button
|
||
(15348); and c) activating the debugger when already active (24455).
|
||
The patch by Mark Roseman does this by making two changes.
|
||
1. Suspend and resume the gui.interaction method with the tcl vwait
|
||
mechanism intended for this purpose (instead of root.mainloop & .quit).
|
||
2. In gui.run, allow any existing interaction to terminate first.
|
||
|
||
- Change 'The program' to 'Your program' in an IDLE 'kill program?' message
|
||
to make it clearer that the program referred to is the currently running
|
||
user program, not IDLE itself.
|
||
|
||
- Issue #24750: Improve the appearance of the IDLE editor window status bar.

|
||
|
||
- Issue #24782: Extension configuration is now a tab in the IDLE Preferences
|
||
dialog rather than a separate dialog. The former tabs are now a sorted
|
||
list. Patch by Mark Roseman.
|
||
|
||
- Issue #22726: Re-activate the config dialog help button with some content
|
||
about the other buttons and the new IDLE Dark theme.
|
||
|
||
- Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
|
||
It is more or less IDLE Classic inverted, with a cobalt blue background.
|
||
Strings, comments, keywords, ... are still green, red, orange, ... .
|
||
To use it with IDLEs released before November 2015, hit the
|
||
'Save as New Custom Theme' button and enter a new name,
|
||
such as 'Custom Dark'. The custom theme will work with any IDLE
|
||
release, and can be modified.
|
||
|
||
- Issue #25224: README.txt is now an idlelib index for IDLE developers and
|
||
curious users. The previous user content is now in the IDLE doc chapter.

Settings -> Custom Highlighting. Original patch by Mark Roseman.

||

|
||

||
|
||

|
||
For Mac OSX, make them a 'sheet'. Patch by Mark Roseman.
|
||
|
||
- Issue #25198: Enhance the initial html viewer now used for Idle Help.
|
||
* Properly indent fixed-pitch text (patch by Mark Roseman).
|
||
* Give code snippet a very Sphinx-like light blueish-gray background.
|
||
* Re-use initial width and height set by users for shell and editor.
|
||
* When the Table of Contents (TOC) menu is used, put the section header

|

- Issue #25199: Idle: add synchronization comments for future maintainers.
|
||
|
||
- Issue #16893: Replace help.txt with help.html for Idle doc display.
|
||
The new idlelib/help.html is rstripped Doc/build/html/library/idle.html.
|
||
It looks better than help.txt and will better document Idle as released.
|
||
The tkinter html viewer that works for this file was written by Mark Roseman.
|
||
The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated.

- Issue #23618: :meth:`socket.socket.connect` now waits until the connection
|
||
completes instead of raising :exc:`InterruptedError` if the connection is

|
||
|
||
- Issue #23752: When built from an existing file descriptor, io.FileIO() now
|
||
only calls fstat() once. Before fstat() was called twice, which was not
|
||
necessary.
|
||
|

|
||

||
at the end of all processing rather than immediately after the first use.

||
arguments of different kinds (UCS1, UCS2, UCS4).
|
||
|

|
||
as repr().

and socket open until the garbage collector cleans them up. Patch by
|
||
Martin Panter.

|
||
importing a test module is now picklable.
|
||
|
||
- Issue #22181: On Linux, os.urandom() now uses the new getrandom() syscall if
|
||
available, syscall introduced in the Linux kernel 3.17. It is more reliable
|
||
and more secure, because it avoids the need of a file descriptor and waits
|
||
until the kernel has enough entropy.
|
||
|
||
- Issue #2211: Updated the implementation of the http.cookies.Morsel class.
|
||
Setting attributes key, value and coded_value directly now is deprecated.
|
||
update() and setdefault() now transform and check keys. Comparing for
|
||
equality now takes into account attributes key, value and coded_value.

|
||
handle exceptions raised by an iterator. Patch by Alon Diamant and Davin
|
||
Potts.

|
||
descriptors. Patch by Wei Wu.

||
Original patch by Tal Einat.
|
||
|
||
- Issue #16233: A module browser (File : Class Browser, Alt+C) requires an
|
||
editor window with a filename. When Class Browser is requested otherwise,
|
||
from a shell, output window, or 'Untitled' editor, Idle no longer displays
|
||
an error box. It now pops up an Open Module box (Alt+M). If a valid name
|
||
is entered and a module is opened, a corresponding browser is also opened.
|
||
|
||
- Issue #4832: Save As to type Python files automatically adds .py to the
|

|
||
|
||
- Issue #18104: Add idlelib/idle_test/htest.py with a few sample tests to begin
|
||
consolidating and improving human-validated tests of Idle. Change other files
|
||
as needed to work with htest. Running the module as __main__ runs all tests.
|
||
|
||
- Issue #21139: Change default paragraph width to 72, the PEP 8 recommendation.
|
||
|
||
- Issue #21284: Paragraph reformat test passes after user changes reformat width.

|
||
Build
|
||
-----
|
||
|
||
- Issue #15506: Use standard PKG_PROG_PKG_CONFIG autoconf macro in the configure
|
||
script.
|
||
|
||
- Issue #22935: Allow the ssl module to be compiled if openssl doesn't support
|
||
SSL 3.
|
||
|
||
- Issue #22592: Drop support of the Borland C compiler to build Python. The
|
||
distutils module still supports it to build extensions.
|
||
|
||
- Issue #22591: Drop support of MS-DOS, especially of the DJGPP compiler
|
||
(MS-DOS port of GCC).
|
||
|
||
- Issue #16537: Check whether self.extensions is empty in setup.py. Patch by
|
||
Jonathan Hosmer.
|
||
|
||
- Issue #22359: Remove incorrect uses of recursive make. Patch by Jonas
|
||
Wagner.
|
||
|
||
- Issue #21958: Define HAVE_ROUND when building with Visual Studio 2013 and
|
||
above. Patch by Zachary Turner.
|
||
|
||
- Issue #18093: the programs that embed the CPython runtime are now in a
|
||
separate "Programs" directory, rather than being kept in the Modules
|
||
directory.
|
||
|
||
- Issue #15759: "make suspicious", "make linkcheck" and "make doctest" in Doc/
|
||
now display special message when and only when there are failures.
|
||
|
||
- Issue #21141: The Windows build process no longer attempts to find Perl,
|
||
instead relying on OpenSSL source being configured and ready to build. The
|
||
``PCbuild\build_ssl.py`` script has been re-written and re-named to
|
||
``PCbuild\prepare_ssl.py``, and takes care of configuring OpenSSL source
|
||
for both 32 and 64 bit platforms. OpenSSL sources obtained from
|
||
svn.python.org will always be pre-configured and ready to build.
|
||
|
||
- Issue #21037: Add a build option to enable AddressSanitizer support.
|
||
|
||
- Issue #19962: The Windows build process now creates "python.bat" in the
|
||
root of the source tree, which passes all arguments through to the most
|
||
recently built interpreter.
|
||
|
||
- Issue #21285: Refactor and fix curses configure check to always search
|
||
in a ncursesw directory.
|
||
|
||
- Issue #15234: For BerkelyDB and Sqlite, only add the found library and
|
||
include directories if they aren't already being searched. This avoids
|
||
an explicit runtime library dependency.
|
||
|
||
- Issue #17861: Tools/scripts/generate_opcode_h.py automatically regenerates
|
||
Include/opcode.h from Lib/opcode.py if the latter gets any change.
|
||
|
||
- Issue #20644: OS X installer build support for documentation build changes
|
||
in 3.4.1: assume externally supplied sphinx-build is available in /usr/bin.
|
||
|
||
- Issue #20022: Eliminate use of deprecated bundlebuilder in OS X builds.
|
||
|
||
- Issue #15968: Incorporated Tcl, Tk, and Tix builds into the Windows build
|
||
solution.
|
||
|
||
- Issue #17095: Fix Modules/Setup *shared* support.
|
||
|
||
- Issue #21811: Anticipated fixes to support OS X versions > 10.9.
|
||
|
||
- Issue #21166: Prevent possible segfaults and other random failures of
|
||
python --generate-posix-vars in pybuilddir.txt build target.
|
||
|
||
- Issue #18096: Fix library order returned by python-config.
|
||
|
||
- Issue #17219: Add library build dir for Python extension cross-builds.
|
||
|
||
- Issue #22919: Windows build updated to support VC 14.0 (Visual Studio 2015),
|
||
which will be used for the official release.
|
||
|
||
- Issue #21236: Build _msi.pyd with cabinet.lib instead of fci.lib
|
||
|
||
- Issue #17128: Use private version of OpenSSL for OS X 10.5+ installer.
|
||
|
||
C API
|
||
-----
|
||
|
||
- Issue #14203: Remove obsolete support for view==NULL in PyBuffer_FillInfo(),
|
||
bytearray_getbuffer(), bytesiobuf_getbuffer() and array_buffer_getbuf().
|
||
All functions now raise BufferError in that case.
|
||
|
||
- Issue #22445: PyBuffer_IsContiguous() now implements precise contiguity
|
||
tests, compatible with NumPy's NPY_RELAXED_STRIDES_CHECKING compilation
|
||
flag. Previously the function reported false negatives for corner cases.
|
||
|
||
- Issue #22079: PyType_Ready() now checks that statically allocated type has
|
||
no dynamically allocated bases.
|
||
|
||
- Issue #22453: Removed non-documented macro PyObject_REPR().
|
||
|
||
- Issue #18395: Rename ``_Py_char2wchar()`` to :c:func:`Py_DecodeLocale`,
|
||
rename ``_Py_wchar2char()`` to :c:func:`Py_EncodeLocale`, and document
|
||
these functions.
|
||
|
||
- Issue #21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(),
|
||
PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) is now using
|
||
``calloc()`` instead of ``malloc()`` for large objects which is faster and
|
||
use less memory.
|
||
|
||
- Issue #20942: PyImport_ImportFrozenModuleObject() no longer sets __file__ to
|
||
match what importlib does; this affects _frozen_importlib as well as any
|
||
module loaded using imp.init_frozen().
|
||
|
||
Documentation
|
||
-------------
|
||
|
||
- Issue #19548: Update the codecs module documentation to better cover the
|
||
distinction between text encodings and other codecs, together with other
|
||
clarifications. Patch by Martin Panter.
|
||
|
||
- Issue #22394: Doc/Makefile now supports ``make venv PYTHON=../python`` to
|
||
create a venv for generating the documentation, e.g.,
|
||
``make html PYTHON=venv/bin/python3``.
|
||
|
||
- Issue #21514: The documentation of the json module now refers to new JSON RFC
|
||
7159 instead of obsoleted RFC 4627.
|
||
|
||
- Issue #21777: The binary sequence methods on bytes and bytearray are now
|
||
documented explicitly, rather than assuming users will be able to derive
|
||

||
|
||
- Issue #6916: undocument deprecated asynchat.fifo class.
|
||

|
||
mention the ability to load the OS certificates.
|
||
|
||
- Issue #20765: Add missing documentation for PurePath.with_name() and
|
||
PurePath.with_suffix().
|
||
|
||
- Issue #19407: New package installation and distribution guides based on
|
||
the Python Packaging Authority tools. Existing guides have been retained
|
||
as legacy links from the distutils docs, as they still contain some
|
||
required reference material for tool developers that isn't recorded
|
||
anywhere else.
|
||
|
||
- Issue #19697: Document cases where __main__.__spec__ is None.
|
||

|
||
so that packet filtering software (specifically Windows Base Filtering Engine)
|

||
|
||
- Issue #19493: Refactored the ctypes test package to skip tests explicitly

|
||
regrtest.py.
