bpo-32929: Dataclasses: Change the tri-state hash parameter to the boolean unsafe_hash. (GH-5891) (GH-5902)
unsafe_hash=False is now the default. It is the same behavior as the old hash=None parameter. unsafe_hash=True will try to add __hash__. If it already exists, TypeError is raised.

Exhaustively test dataclass hashing when no hash= value is provided. This is in anticipation of changing how non-default hashing is handled. (GH-5834) (GH-5889)
This code never did anything correct or useful. The class attribute will never be affected, and the condition will never be true.

[3.7] bpo-30622: Improve NPN support detection (GH-5859) (#5860)
The ssl module now detects missing NPN support in LibreSSL.

* The SSLSocket is no longer implemented on top of SSLObject to
avoid an extra level of indirection.
* Owner and session are now handled in the internal constructor.
* _ssl._SSLSocket now uses the same method names as SSLSocket and
SSLObject.
* Channel binding type check is now handled in C code. Channel binding
is always available.
The patch also changes the signature of SSLObject.__init__(). In my
opinion it's fine. A SSLObject is not a user-constructable object.
SSLContext.wrap_bio() is the only valid factory.

[3.7] bpo-32819: Simplify and improve ssl.match_hostname (GH-5620) (#5847)
ssl.match_hostname() has been simplified and no longer depends on re and
ipaddress module for wildcard and IP addresses. Error reporting for invalid
wildcards has been improved.
[bpo-28414] Make all hostnames in SSL module IDN A-labels (GH-5128) (GH-5843)
Previously, the ssl module stored international domain names (IDNs)
as U-labels. This is problematic for a number of reasons -- for
example, it made it impossible for users to use a different version
of IDNA than the one built into Python.
After this change, we always convert to A-labels as soon as possible,
and use them for all internal processing. In particular, server_hostname
attribute is now an A-label, and on the server side there's a new
sni_callback that receives the SNI servername as an A-label rather than
a U-label.

bpo-32923: Unittest doc: replace `whilst` with `while` (GH-5833)

bpo-30028: make test.support.temp_cwd() fork-safe (GH-1066)
Make test.support.temp_cwd() fork-safe. The context manager test.support.temp_cwd() no longer removes the temporary directory when executing in a process other than the parent it entered from.
If a forked child exits the context manager it won't do the cleanup.

bpo-32604: Swap threads only if the interpreter is different. (gh-5783)
The CPython runtime assumes that there is a one-to-one relationship (for a given interpreter) between PyThreadState and OS threads. Sending and receiving on a channel in the same interpreter was causing crashes because of this (specifically due to a check in PyThreadState_Swap()). The solution is to not switch threads if the interpreter is the same.

closes bpo-32859: Don't retry dup3() if it is not available at runtime (GH-5708)
os.dup2() tests for dup3() system call availability at runtime,
but doesn't remember the result across calls, repeating
the test on each call with inheritable=False.
Since the caller of os.dup2() is expected to hold the GIL,
fix this by making the variable holding the test result static.

DOC: fix documentation for copyright and credits (GH-5706)
Adapt documentation for `copyright` and `credits` to reality. Previously, the documentation implied that all each of `copyright`,
`credits`, and `license`, would print a message to call the object in order to see the full text. In reality, only `license` exhibits this
behaviour, and `copyright` and `credit` print their full text either when printed, displayed, or called.

readline() internally reads and decodes far enough ahead to encounter
a non-ascii character in CREDITS.txt.

bpo-32775: Fix regular expression warnings in fnmatch. (GH-5583) (GH-5596)
fnmatch.translate() no longer produces patterns which contain set

be interpreted differently in regular expressions in future versions.
Currently they emit warnings. fnmatch.translate() now avoids producing

bpo-32777: Fix _Py_set_inheritable async-safety in subprocess (GH-5560) (GH-5562)
Fix a rare but potential pre-exec child process deadlock in subprocess on POSIX systems when marking file descriptors inheritable on exec in the child process. This bug appears to have been introduced in 3.4 with the inheritable file descriptors support.
This also changes Python/fileutils.c `set_inheritable` to use the "slow" two `fcntl` syscall path instead of the "fast" single `ioctl` syscall path when asked to be async signal safe (by way of being asked not to raise exceptions). `ioctl` is not a POSIX async-signal-safe approved function.

method (including property methods).
