The `update` method calls `self[key] = message` for each `(key, message)`
pair so it also accepts all the same message types as the `__setitem__`
method. Fix the signature so that the inputs are not restricted to
`Message` instances or to instance of the `_MessageType` type parameter,
but to the more reluctant `_MessageData` type alias.
* mailbox: Make stub-only helpers private
These HasIteritems and HasItems protocols don't exist in the real
mailbox module so prefix them with underscore to indicate they are
private.
* mailbox: Fix type of message argument
The Mailbox.add and Mailbox.__setitem__ methods take a message argument
which can be anything that is convertible to a Message. Fix the
signatures accordingly.
Fix errors discovered by running typeshed check on Windows. This is a temporary fix for #3446 (in long term we should figure out why these were not caught by typeshed CI).
I also remove an outdated comment while I am at it.
* Add os.add_dll_directory()
* Add memfd_create() and flags
* Add type annotation to flags
* Add stat_result.st_reparse_tag and flags
* Add ncurses_version

* Add Picker.reducer_override()
* Add plistlib.UID
* Add has_dualstack_ipv6() and create_server()
* Add shlex.join()
* Add SSL methods and fields
* Add Python 3.8 statistics functions and classes
* Remove obsolete sys.subversion
* Add sys.unraisablehook
* Add threading.excepthook
* Add get_native_id() and Thread.native_id
* Add Python 3.8 tkinter methods
* Add CLOCK_UPTIME_RAW
* Add SupportsIndex
* Add typing.get_origin() and get_args()
* Add unicodedata.is_normalized
* Add unittest.mock.AsyncMock
Currently this is just an alias for Any like Mock and MagicMock. All of
these classes should probably be sub-classing Any and add their own
methods. See also #3224.
* Add unittest cleanup methods
* Add IsolatedAsyncioTestCase
* Add ElementTree.canonicalize() and C14NWriterTarget
* cProfile.Profile can be used as a context manager
* Add asyncio task name handling
* mmap.flush() now always returns None
* Add posonlyargcount to CodeType
While it may eventually be useful to mark the exceptions that can be
raised from a function or method, the semantics are currently undefined
and unclear.
This is a continuation of #3291, which was the initial fix for #3201.
The 2-arg version of iter() turns a callable into an iterator. The
changes made in #3291 introduce an Any return type for both the
callable's return type and the iterator's type, while in reality the
return type of the function is always the same as the iterator's type.
PR #3269 added some version checks for the argument type to setLevel
and the existence of NullHandler. While these features weren't present
in early versions of Python 3, they *are* present in Python 2.7, which
leads to false positives.
