arriving at unfortunate times.
* bpo-27340: Use memoryview in SSLSocket.sendall()
SSLSocket.sendall() now uses memoryview to create slices of data. This fix
support for all bytes-like object. It is also more efficient and avoids
costly copies.

Add basic fuzz tests for a few common builtin functions.
This is an easy place to start, and these functions are probably safe.
We'll want to add more fuzz tests later. Lets bootstrap using these.
While the fuzz tests are included in CPython and compiled / tested on a
very basic level inside CPython itself, the actual fuzzing happens as
part of oss-fuzz (https://github.com/google/oss-fuzz). The reason to
include the tests in CPython is to make sure that they're maintained
as part of the CPython project, especially when (as some eventually
will) they use internal implementation details in the test.
(This will be necessary sometimes because e.g. the fuzz test should
never enter Python's interpreter loop, whereas some APIs only expose
themselves publicly as Python functions.)
This particular set of changes is part of testing Python's builtins,
tracked internally at Google by b/37562550.
The _xxtestfuzz module that this change adds need not be shipped with binary distributions of Python.
SSLObject.version() now correctly returns None when handshake over BIO has
not been performed yet.

The ssl and hashlib modules now call OPENSSL_add_all_algorithms_noconf() on

* Maintain a list of BufferedWriter objects. Flush them on exit.
In Python 3, the buffer and the underlying file object are separate
and so the order in which objects are finalized matters. This is
unlike Python 2 where the file and buffer were a single object and
finalization was done for both at the same time. In Python 3, if
the file is finalized and closed before the buffer then the data in
the buffer is lost.
This change adds a doubly linked list of open file buffers. An atexit
hook ensures they are flushed before proceeding with interpreter
shutdown. This is addition does not remove the need to properly close
files as there are other reasons why buffered data could get lost during
finalization.
Initial patch by Armin Rigo.
* Use weakref.WeakSet instead of WeakKeyDictionary.
* Simplify buffered double-linked list types.
* In _flush_all_writers(), suppress errors from flush().
* Remove NEWS entry, use blurb.
* bpo-1198569: Allow the braced pattern to be different
``string.Template`` subclasses can optionally define ``braceidpattern`` if
they want to specify different placeholder patterns inside and outside the
braces. If None (the default) it falls back to ``idpattern``.
* bpo-31326: ProcessPoolExecutor waits for the call queue thread
concurrent.futures.ProcessPoolExecutor.shutdown() now explicitly
closes the call queue. Moreover, shutdown(wait=True) now also join
the call queue thread, to prevent leaking a dangling thread.
* Fix for shutdown() being called twice.
* bpo-27144: concurrent.futures as_complie and map iterators do not keep
reference to returned object
* Some nits. Improve wordings in docstrings and comments, and avoid relying on
sys.getrefcount() in tests.
* Fixes#30581 by adding a path to use newer GetMaximumProcessorCount API on Windows calls to os.cpu_count()
* Add NEWS.d entry for bpo-30581, os.cpu_count on Windows.
* Tweak NEWS entry
* Make error message more informative
Replace assertions in error-reporting code with more-informative version that doesn't cause confusion over where and what the error is.
* Additional clarification + get travis to check
* Change from SystemError to TypeError
As suggested in PR comment by @pitrou, changing from SystemError; TypeError appears appropriate.
* NEWS file installation; ACKS addition (will do my best to justify it by additional work)
* Making current AssertionErrors in multiprocessing more informative
* Blurb added re multiprocessing managers.py, queues.py cleanup
* Further multiprocessing cleanup - went through pool.py

* Remove extraneous backslash in docstring.
Ctypes currently produces wrong pep3118 type codes for several types.
E.g. memoryview(ctypes.c_long()).format gives "<l" on 64-bit platforms,
but it should be "<q" instead for sizeof(c_long) == 8
The problem is that the '<>' endian specification in the struct syntax
also turns on the "standard size" mode, which makes type characters have
a platform-independent meaning, which does not match with the codes used
internally in ctypes. The struct module format syntax also does not
allow specifying native-size non-native-endian items.
This commit adds a converter function that maps the internal ctypes
codes to appropriate struct module standard-size codes in the pep3118
format strings. The tests are modified to check for this.
* Added support for CAN_ISOTP protocol
* Added unit tests for CAN ISOTP
* Updated documentation for ISO-TP protocol
* Removed trailing whitespace in documentation

* Removed dependecy over third party project
* Added implementation for getsockname + unit tests
* Missing newline at end of ACKS file
* Accidentally inserted a type in ACKS file
* Followed tiran changes review #1 recommendations
* Added spaces after comma
* bpo-31249: Fix ref cycle in ThreadPoolExecutor
concurrent.futures: WorkItem.run() used by ThreadPoolExecutor now
breaks a reference cycle between an exception object and the WorkItem
object. ThreadPoolExecutor.shutdown() now also clears its threads
set.
* shutdown() now only clears threads if wait is true.
* Revert changes on shutdown()
PEP 523 introduced _PyEval_EvalFrameDefault which inlines PyEval_EvalFrameEx on
non-debug shared builds. This breaks the ability to use py-bt, py-up, and
a few other Python-specific gdb integrations.
This patch fixes the problem by only looking for _PyEval_EvalFrameDefault
frames.
test_gdb passes on both a debug and a non-debug build.
Original patch by Bruno "Polaco" Penteado.
* bpo-31238: pydoc ServerThread.stop() now joins itself
ServerThread.stop() now joins itself to wait until
DocServer.serve_until_quit() completes and then explicitly sets
its docserver attribute to None to break a reference cycle.
* Add NEWS.d entry
This is the first half of a patch similar to the one for for bpo-31205. It is being split into 2 PRs to avoid what happened with PR-3096 -- an incomprehensible diff that could not be cleanly backported to 3.6. This half copies several methods of ConfigDialog and turns them into a new class.
Coroutines and async generators use a distinct attribute name for their
code objects, so this updates the `dis` module to correctly disassemble
objects with those attributes.
Due to the increase in the test module length, it also fixes some latent
defects in the tests related to how the displayed source line numbers
are extracted.
https://bugs.python.org/issue31230 is a follow-up issue suggesting we
may want to solve this a different way, by instead giving all these object
types a common `__code__` attribute, avoiding the need for special
casing in the `dis` module.
* Revert "Add Bruno Penteado to ACKS (#3091)"
This reverts commit f978405b3f.
* Revert "bpo-30983: eval frame rename in pep 0523 broke gdb's python extension (#2803)"

OpenSSL 1.1.0 to 1.1.0e aborted the handshake when server and client

all child processes completed to prevent leaking zombie processes.
* Fix test on Windows which doesn't have ForkingMixIn
Idlelib.calltips.get_argspec now uses inspect.signature instead of inspect.getfullargspec, like help() does. This improves the signature in the call tip in a few different cases, including builtins converted to provide a signature. A message is added if the object is not callable, has an invalid signature, or if it has positional-only parameters.

The notebook looks a bit better. It will work better with separate page classes. Traversal of widgets by Tab works better. Switching tabs with keys becomes possible. The font sample box works better at large font sizes.
One of the two simulated click tests no longer works. This will be investigated while fixing a bug with the widget itself.
Instance tracers manages pairs consisting of a tk variable and a
callback function. When tracing is turned on, setting the variable
calls the function. Test coverage for the new class is 100%.
Finish resorting the 72 ConfigDialog methods into 7 groups that represent the dialog, action buttons, and font, highlight, keys, general, and extension pages. This will help with continuing to add tests and improve the pages. It will enable splitting ConfigDialog into 6 or 7 more comprehensible classes.
* In configdialog: Document causal pathways in create_page_general.
Move related functions to follow this. Simplify some attribute names.
* In test_configdialog: Add tests for load and helplist functions.
Coverage for the general tab is now complete, and 63% overall.
In configdialog: Document causal pathways in create_font_tab docstring. Simplify some attribute names. Move set_samples calls to var_changed_font (idea from Cheryl Sabella). Move related functions to positions after the create widgets function.
In test_configdialog: Fix test_font_set so not order dependent. Fix renamed test_indent_scale so it tests the widget. Adjust tests for movement of set_samples call. Add tests for load functions. Put all font tests in one class and tab indent tests in another. Except for two lines, these tests completely cover the related functions.
* Document causal event pathways in docstring.
* Simplify some attribute names.
* Rename test_bold_toggle_set_samples to make test_font_set fail.
* Fix test_font_set so not order dependent.
* Fix renamed test_indent_scale so it tests the widget.
* bpo-26732: fix too many fds in processes started with the "forkserver" method
A child process would inherit as many fds as the number of still-running children.
* Add blurb and test comment
* bpo-19896: Add typcodes 'q' and 'Q' to multiprocessing.sharedctypes. Patch by Antony Lee.
* Add NEWS entry.
* Slightly tweak NEWS entry
Make it clear this is more of a fix rather than a new feature.
Adds a new 'Pip not installed' section that covers
running `ensurepip` manually, and also references
the relevant section of the Python Packaging User
Guide.
When running the test suite using --use=all / -u all, exclude tzdata
since it makes test_datetime too slow (15-20 min on some buildbots)
which then times out on some buildbots.
-u tzdata must now be enabled explicitly, -u tzdata or -u all,tzdata,
to run all test_datetime tests.
Fix also regrtest command line parser to allow passing -u
extralargefile to run test_zipfile64.
Travis CI: remove -tzdata. Replace -u all,-tzdata,-cpu with -u all,-cpu since tzdata is now excluded from -u all.
Cython will, in the right circumstances, offer a MethodType instance
where im_func is a builtin function. Any instance of MethodType is
automatically assumed to be a Python-defined function (more
specifically, a function that has an inspectable signature), but
_set_signature was still conservative in its assumptions. As a result
_set_signature would return early with None instead of a mock since
the im_func had no inspectable signature. This causes problems
deeper inside mock, as _set_signature is assumed to _always_
return a mock, and nothing checked its return value.
In similar corner cases, autospec will simply not check the spec of the
function, so _set_signature is amended to now return early with the
original, not-wrapped mock object.

multiprocessing.Queue.join_thread() now waits until the thread
completes, even if the thread was started by the same process which
created the queue.
Fix the following warning which occurs randomly when running
test_handle_called_with_mp_queue of test_logging.QueueListenerTest:
Warning -- threading_cleanup() failed to cleanup -1 threads after 4 sec (count: 0, dangling: 1)
If history-length is set in .inputrc, and the history file is double the
history size (or more), history_get(N) returns NULL, and python
segfaults. Fix that by checking for NULL return value.
It seems that the root cause is incorrect handling of bigger history in
readline, but Python should not segfault even if readline returns
unexpected value.
This issue affects only GNU readline. When using libedit emulation
system history size option does not work.
* bpo-30832: Remove own implementation for thread-local storage
CPython has provided the own implementation for thread-local storage
(TLS) on Python/thread.c, it's used in the case which a platform has
not supplied native TLS. However, currently all supported platforms
(NT and pthreads) have provided native TLS and defined the
Py_HAVE_NATIVE_TLS macro with unconditional in any case.
