Python 3.8 3.8.7 ჩამოტვირთვა

Core and Builtins
- bpo-32381: Fix encoding name when running a .pyc file on Windows: PyRun_SimpleFileExFlags() now uses the correct encoding to decode the filename.
- bpo-42536: Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector:
- collections.OrderedDict.items()
- dict.items()
- enumerate()
- functools.reduce()
- itertools.combinations()
- itertools.combinations_with_replacement()
- itertools.permutations()
- itertools.product()
- itertools.zip_longest()
- zip()
Previously, they could have become untracked by a prior garbage collection. Patch by Brandt Bucher.
Library
- bpo-42630: tkinter functions and constructors which need a default root window raise now RuntimeError with descriptive message instead of obscure AttributeError or NameError if it is not created yet or cannot be created automatically.
- bpo-42644: logging.disable will now validate the types and value of its parameter. It also now accepts strings representing the levels (as does loging.setLevel) instead of only the numerical values.
- bpo-36541: Fixed lib2to3.pgen2 to be able to parse PEP-570 positional only argument syntax.
- bpo-42375: subprocess module update for DragonFlyBSD support.
- bpo-39825: Windows: Change sysconfig.get_config_var('EXT_SUFFIX') to the expected full platform_tag.extension format. Previously it was hard-coded to .pyd, now it is compatible with distutils.sysconfig and will result in something like .cp38-win_amd64.pyd. This brings windows into conformance with the other platforms.
- bpo-39101: Fixed tests using IsolatedAsyncioTestCase from hanging on BaseExceptions.
- bpo-41907: fix format() behavior for IntFlag
- bpo-41889: Enum: fix regression involving inheriting a multiply-inherited enum
- bpo-41891: Ensure asyncio.wait_for waits for task completion
- bpo-40219: Lowered tkinter.ttk.LabeledScale dummy widget to prevent hiding part of the content label.
- bpo-40084: Fix Enum.__dir__: dir(Enum.member) now includes attributes as well as methods.
Documentation
- bpo-17140: Add documentation for the multiprocessing.pool.ThreadPool class.
Build
- bpo-42604: Now all platforms use a value for the “EXT_SUFFIX” build variable derived from SOABI (for instance in freeBSD, “EXT_SUFFIX” is now “.cpython-310d.so” instead of “.so”). Previosuly only Linux, Mac and VxWorks were using a value for “EXT_SUFFIX” that included “SOABI”.
- bpo-42598: Fix implicit function declarations in configure which could have resulted in incorrect configuration checks. Patch contributed by Joshua Root.
Tools/Demos
- bpo-42613: Fix freeze.py tool to use the prope config and library directories. Patch by Victor Stinner.
