Anthony Sottile abea73bf4a bpo-2180: Treat line continuation at EOF as a `SyntaxError` (GH-13401)
This makes the parser consistent with the tokenize module (already the case
in `pypy`).

sample
------

```python
x = 5\
```

before
------

```console
$ python3 t.py
$ python3 -mtokenize t.py
t.py:2:0: error: EOF in multi-line statement
```

after
-----

```console
$ ./python t.py
  File "t.py", line 3
    x = 5\

         ^
SyntaxError: unexpected EOF while parsing
$ ./python -m tokenize t.py
t.py:2:0: error: EOF in multi-line statement
```

‮zlohhcuB treboR d9e006bcef bpo-33123: pathlib: Add missing_ok parameter to Path.unlink (GH-6191)
Similarly to how several pathlib file creation functions have an "exists_ok" parameter, we should introduce "missing_ok" that makes removal functions not raise an exception when a file or directory is already absent.  IMHO, this should cover Path.unlink and Path.rmdir.  Note, Path.resolve() has a "strict" parameter since 3.6 that does the same thing. Naming this of this new parameter tries to be consistent with the "exists_ok" parameter as that is more explicit about what it does (as opposed to "strict").

Plistlib currently throws an exception when asked to decode a valid

this is caused by a byte 0x80 (signifying a UID) not being understood.

This fixes the problem by enabling the binary plist reader and writer
to read and write plistlib.UID objects.

bpo-36915: regrtest always remove tempdir of worker processes (GH-13312)
When using multiprocessing (-jN option), worker processes now create
their temporary directory inside the temporary directory of the
main process. So the main process is able to remove temporary
directories of worker processes even if they crash or when they are
killed by regrtest on KeyboardInterrupt (CTRL+c).

Rework also how multiprocessing arguments are parsed in main.py.

Vincent Michel 63deaa5b70 bpo-31922: Do not connect UDP sockets when broadcast is allowed (GH-423)
*Moved from python/asyncio#493.*

This PR fixes issue python/asyncio#480, as explained in [this comment](https://github.com/python/asyncio/issues/480#issuecomment-278703828).

The `_SelectorDatagramTransport.sendto` method has to be modified ~~so `_sock.sendto` is used in all cases (because it is tricky to reliably tell if the socket is connected or not). Could that be an issue for connected sockets?~~ *EDIT* ... so `_sock.send` is used only if `_sock` is connected.

It also protects `socket.getsockname` against `OSError` in `_SelectorTransport`. This might happen on Windows if the socket is not connected (e.g. for UDP broadcasting).

bpo-35925: Skip SSL tests that fail due to weak external certs. (GH-13124)
Modern Linux distros such as Debian Buster have default OpenSSL system

resources enabled to skip these tests when they encounter such a failure.

Fixing the network servers is a separate issue.

bpo-34602: Avoid failures setting macOS stack resource limit (GH-13011)
Under some conditions the earlier fix for bpo-18075, "Infinite recursion
tests triggering a segfault on Mac OS X", now causes failures on macOS
when attempting to change stack limit with resource.setrlimit
resource.RLIMIT_STACK, like regrtest does when running the test suite.
The reverted change had specified a non-default stack size when linking
the python executable on macOS.  As of macOS 10.14.4, the previous
code causes a hard failure when running tests, although similar
failures had been seen under some conditions under some earlier
systems.  For now, revert the original change and resume using
the default stack size when linking the interpreter.

Paul Ganssle 4d8c8c0ad6 bpo-36025: Fix PyDate_FromTimestamp API (GH-11922)
In the process of converting the date.fromtimestamp function to use
argument clinic in GH-8535, the C API for PyDate_FromTimestamp was
inadvertently changed to expect a timestamp object rather than an
argument tuple.

This PR fixes this backwards-incompatible change by adding a new wrapper
function for the C API function that unwraps the argument tuple and
passes it to the underlying function.

This PR also adds tests for both PyDate_FromTimestamp and
PyDateTime_FromTimestamp to prevent any further regressions.

  the main thread. No longer ignore BaseException or parsing errors
  silently.
* Remove 'finished' variable: use worker.is_alive() instead

On Unix, C extensions are no longer linked to libpython.

It is now possible to load a C extension built using a shared library

When Python is embedded, libpython must not be loaded with
RTLD_LOCAL, but RTLD_GLOBAL instead. Previously, using RTLD_LOCAL, it
was already not possible to load C extensions which were not linked
to libpython, like C extensions of the standard library built by the
"*shared*" section of Modules/Setup.

bpo-35755: shutil.which() uses os.confstr("CS_PATH") (GH-12858)
shutil.which() and distutils.spawn.find_executable() now use
os.confstr("CS_PATH") if available instead of os.defpath, if the PATH
environment variable is not set.

Don't use os.confstr("CS_PATH") nor os.defpath if the PATH
environment variable is set to an empty string to mimick Unix 'which'
command behavior.

Changes:

* find_executable() now starts by checking for the executable in the
  current working directly case. Add an explicit
  "if not path: return None".
* Add tests for PATH='' (empty string), PATH=':' and for PATHEXT.

bpo-36348: IMAP4.logout() doesn't ignore exc (GH-12411)
The imap.IMAP4.logout() method no longer ignores silently arbitrary
exceptions.

Changes:

* The IMAP4.logout() method now expects a "BYE" untagged response,
  rather than relying on _check_bye() which raises a self.abort()
  exception.
* IMAP4.__exit__() now does nothing if the client already logged out.
* Add more debug info if test_logout() tests fail.

Xtreak 830b43d03c bpo-36593: Fix isinstance check for Mock objects with spec executed under tracing (GH-12790)
In Python having a trace function in effect while mock is imported causes isinstance to be wrong for MagicMocks. This is due to the usage of super() in some class methods, as this sets the __class__ attribute. To avoid this, as a workaround, alias the usage of super .

bpo-36611: Disable serialno field of debug memory allocators (#12796)
Omit serialno field from debug hooks on Python memory allocators to
reduce the memory footprint by 5%.

Enable tracemalloc to get the traceback where a memory block has been
allocated when a fatal memory error is logged to decide where to put
a breakpoint.

Compile Python with PYMEM_DEBUG_SERIALNO defined to get back the
field.

bpo-36618: Add -fmax-type-align=8 flag for clang (GH-12809)
Add -fmax-type-align=8 to CFLAGS when clang compiler is detected.

The pymalloc memory allocator aligns memory on 8 bytes. On x86-64,
clang expects alignment on 16 bytes by default and so uses MOVAPS
instruction which can lead to segmentation fault. Instruct clang that
Python is limited to alignemnt on 8 bytes to use MOVUPS instruction
instead: slower but don't trigger a SIGSEGV if the memory is not
aligned on 16 bytes.

Sadly, the flag must be expected to CFLAGS and not just
CFLAGS_NODIST, since third party C extensions can have the same
issue.
