* [3.6] bpo-30703: Improve signal delivery (GH-2415)

* Improve signal delivery

Avoid using Py_AddPendingCall from signal handler, to avoid calling signal-unsafe functions.

* Remove unused function

* Improve comments

* Add stress test

* Adapt for --without-threads

* Add second stress test

* Add NEWS blurb

* Address comments @haypo.
(cherry picked from commit c08177a1ccad2ed0d50898c2731b518c631aed14)

* bpo-30796: Fix failures in signal delivery stress test (#2488)

* bpo-30796: Fix failures in signal delivery stress test

setitimer() can have a poor minimum resolution on some machines,
this would make the test reach its deadline (and a stray signal
could then kill a subsequent test).

* Make sure to clear the itimer after the test

  [2.7] Rename test_ file that is really a support file to remove test_ prefix. (#2548)

I thought I had run the full test suite before the last checkin, but
obviously I didn't.  test_multibytecodec_support.py isn't really a test file,
it is a support file that contains a base test class.  Rename it to
multibytecodec_support so that regrtest test discovery doesn't think it is a
test file that should be run..

Sleep 1 ms instead of 0.1 ms to workaround a rounding issue on
Windows. On Windows, time.sleep(0.0001) sleeps 0 ms, so
collect_in_thread() calls gc.collect() in a loop and tests using this
thread takes too long. Sleep 1 ms so time.sleep() sleeps 15.6 ms on
Windows.

In setUp() and tearDown() methods of test_concurrent_futures tests,
make sure that tests don't leak threads nor processes. Clear
explicitly the reference to the executor to make it that it's
destroyed (to prevent "dangling threads" warning).

  bpo-29854: Fix segfault in call_readline() (GH-728)

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.

The current regex based splitting produces a wrong result. For example::

  http://abc#@def

Web browsers parse that URL as ``http://abc/#@def``, that is, the host
is ``abc``, the path is ``/``, and the fragment is ``#@def``.

bpo-30726, bpo-29591: libexpat 2.2.1 of Modules/expat/ now uses
a winconfig.h configuration file which already defines:

* XML_NS
* XML_DTD
* BYTEORDER=1234
* XML_CONTEXT_BYTES=1024
* HAVE_MEMMOVE

Remove these defines from PCbuild/_elementtree.vcxproj to prevent
compiler warnings.

  bpo-29854: Skip history-size test on older readline (GH-2621)

Turns out that history-size was added in readline 6.0. This explain why
this tests fail on FreeBSD when using readline 5.2. We skip now the
history size if readline does not support it.

See https://cnswww.cns.cwru.edu/php/chet/readline/CHANGES for
details.

  [3.6] bpo-29854: Fix segfault in call_readline() (GH-728)

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.

  [2.7] bpo-29854: Fix segfault in call_readline() (GH-728)

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.

This is a backport of the actual fix from master without the test, since
the test depends on new run_pty() helper which is not available in 2.7.

performance changes against the previous stable version and the previous nightly
measurement. This is provided as a service to the community so that quality
issues with current hardware can be identified quickly.

Intel technologies' features and benefits depend on system configuration and may
require enabled hardware, software or service activation. Performance varies
depending on system configuration.

* bpo-29591: Upgrade Modules/expat to libexpat 2.2

* bpo-29591: Restore Python changes on expat

* bpo-29591: Remove expat config of unsupported platforms

Remove the configuration (Modules/expat/*config.h) of unsupported
platforms:

* Amiga
* MacOS Classic on PPC32
* Open Watcom

* bpo-29591: Remove useless XML_HAS_SET_HASH_SALT

The XML_HAS_SET_HASH_SALT define of Modules/expat/expat.h became
useless since our local expat copy was upgrade to expat 2.1 (it's now
expat 2.2.0).

(cherry picked from commit 23ec4b57e1359f9c539b8defc317542173ae087e)

* bpo-30726: PCbuild _elementtree: remove duplicate defines (#2348)

bpo-30726, bpo-29591: libexpat 2.2.1 of Modules/expat/ now uses
a winconfig.h configuration file which already defines:

* XML_NS
* XML_DTD
* BYTEORDER=1234
* XML_CONTEXT_BYTES=1024
* HAVE_MEMMOVE

Remove these defines from PCbuild/_elementtree.vcxproj to prevent
compiler warnings.

* bpo-30726: Fix elementtree warnings on Windows due to expat upgrade (#2319)

* bpo-30726: Fix elementtree warnings on Windows

Caused by usage of `getenv` which should be safe. And a few integer
truncations which should also be ok.

* bpo-30726: Don't ignore libexpat warnings which haypo intends to fix upstream

  bpo-30500: urllib: Simplify splithost by calling into urlparse. (#1849) (#2291)

The current regex based splitting produces a wrong result. For example::

  http://abc#@def

Web browsers parse that URL as ``http://abc/#@def``, that is, the host
is ``abc``, the path is ``/``, and the fragment is ``#@def``.

checks if all threads have been cleaned up.

(...)
Warning -- threading_cleanup() failed to cleanup 0 threads after 3 sec (count: 0, dangling: 2)

  bpo-30836: fix test_c_locale_coercion on AIX

AIX uses latin-1 in the C locale, not ASCII

AIX doesn't currently provide any of the locale
coercion locales, but we leave locale coercion
enabled in case one gets added in the future.

  [3.3] bpo-29591, bpo-30694: Upgrade Modules/expat to libexpat 2.2.1 (#2164) (#2204)

* bpo-29591: Upgrade Modules/expat to libexpat 2.2 (#2164)

* bpo-29591: Upgrade Modules/expat to libexpat 2.2

* bpo-29591: Restore Python changes on expat

* bpo-29591: Remove expat config of unsupported platforms

Remove the configuration (Modules/expat/*config.h) of unsupported
platforms:

* Amiga
* MacOS Classic on PPC32
* Open Watcom

* bpo-29591: Remove useless XML_HAS_SET_HASH_SALT

The XML_HAS_SET_HASH_SALT define of Modules/expat/expat.h became
useless since our local expat copy was upgrade to expat 2.1 (it's now
expat 2.2.0).

(cherry picked from commit 23ec4b57e1359f9c539b8defc317542173ae087e)

* bpo-30694: Upgrade Modules/expat/ to libexpat 2.2.1 (#2300)

New file: Modules/expat/siphash.h.
(cherry picked from commit 5ff7132313eb651107b179d20218dfe5d4e47f13)

* bpo-30726: PCbuild _elementtree: remove duplicate defines (#2348)

bpo-30726, bpo-29591: libexpat 2.2.1 of Modules/expat/ now uses
a winconfig.h configuration file which already defines:

* XML_NS
* XML_DTD
* BYTEORDER=1234
* XML_CONTEXT_BYTES=1024
* HAVE_MEMMOVE

Remove these defines from PCbuild/_elementtree.vcxproj to prevent
compiler warnings.

Co-Authored-By: Jeremy Kloth <jeremy.kloth at gmail.com>
(cherry picked from commit c8fb58bd7917151e63398587a7fc2126db7c26de)

* bpo-30726: Fix elementtree warnings on Windows due to expat upgrade (#2319)

* bpo-30726: Fix elementtree warnings on Windows

Caused by usage of `getenv` which should be safe. And a few integer
truncations which should also be ok.

* bpo-30726: Don't ignore libexpat warnings which haypo intends to fix upstream

(cherry picked from commit 87c65550730a8f85ce339ba197bce4fb7e836619)

  bpo-29403: Fix mock's broken autospec behavior on method-bound builtin functions (GH-3)

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.

Patch by Aaron Gallagher.

  bpo-30822: Exclude tzdata from regrtest --all (#2775)

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.

  bpo-30822: Exclude tzdata from regrtest --all (#2775) (#2781)

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.

Remove also _bootstrap._POPULATE since it was unused

  [3.6] bpo-29403: Fix mock's broken autospec behavior on method-bound builtin functions (GH-3)

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.

  [3.5] bpo-29403: Fix mock's broken autospec behavior on method-bound builtin functions (GH-3)

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.

Patch by Aaron Gallagher.

[3.5] Backport bpo-30876 (GH-2639), bpo-18018 and bpo-26367. (#2677)

* bpo-30876: Relative import from unloaded package now reimports the package
instead of failing with SystemError.

Relative import from non-package now fails with ImportError rather than
SystemError.
(cherry picked from commit 8a9cd20edca7d01b68292036029ae3735ce65edd)

* bpo-18018: Import raises ImportError instead of SystemError if a relative
import is attempted without a known parent package.

* bpo-26367: importlib.__init__() raises ImportError like
builtins.__import__() when ``level`` is specified but without an accompanying
package specified.

summary:

bpo-30993: IDLE - Improve configdialog font page and tests.  (#2818)

* 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.

summary:

bpo-30993: IDLE - Improve configdialog font page and tests. (#2831)

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.

summary:

[3.6] bpo-30993: IDLE - Improve configdialog font page and tests. (GH-2831) (#2834)

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.

+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.

test_bsddb3 tolerates smaller timeout on Windows (#2840)

bpo-30850: On Windows, test04_lock_timeout2() now tolerates 50 ms
whereas 100 ms is expected. The lock sometimes times out after only
58 ms. Windows clocks have a bad resolution and bad accuracy.

bpo-26762: Avoid daemon process in _test_multiprocessing (#2842)

test_level() of _test_multiprocessing._TestLogging now uses regular
processes rather than daemon processes to prevent zombi processes
(to not "leak" processes).

bpo-30908: Fix dangling thread in test_os.TestSendfile (#2680) (#2845)

tearDown() now clears explicitly the self.server variable to make
sure that the thread is completely cleared when tearDownClass()
checks if all threads have been cleaned up.

Fix the following warning:

$ ./python -m test --fail-env-changed -m test.test_os.TestSendfile.test_keywords -R 3:1 test_os
(...)
Warning -- threading_cleanup() failed to cleanup 0 threads after 3 sec (count: 0, dangling: 2)

summary:

bpo-30980: Fix double close in asyncore.file_wrapper (#2789)

* bpo-30980: Fix close test to fail

test_close_twice was not considering the fact that file_wrapper is
duping the file descriptor. Closing the original descriptor left the
duped one open, hiding the fact that close protection is not effective.

* bpo-30980: Fix double close protection

Invalidated self.fd before closing, handling correctly the case when
os.close raises.

* bpo-30980: Fix fd leak introduced in the fixed test

summary:

test_multiprocessing detects dangling per test case (#2841)

bpo-26762: test_multiprocessing now detects dangling processes and
threads per test case classes:

* setUpClass()/tearDownClass() of mixin classes now check if
  multiprocessing.process._dangling or threading._dangling was
  modified to detect "dangling" processses and threads.
* ManagerMixin.tearDownClass() now also emits a warning if it still
  has more than one active child process after 5 seconds.
* tearDownModule() now checks for dangling processes and threads
  before sleep 500 ms. And it now only sleeps if there is a least one
  dangling process or thread.

-  of datetime.datetime: microseconds are now rounded to nearest with ties

-  It also the rounding mode used by round(float) for example.

-IDLE

-  This prevents the RuntimeErrors that were being caught and ignored.
-
-- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
-  debugger is active (15347); b) closing the debugger with the [X] button
-  (15348); and c) activating the debugger when already active (24455).
-  The patch by Mark Roseman does this by making two changes.
-  1. Suspend and resume the gui.interaction method with the tcl vwait
-  mechanism intended for this purpose (instead of root.mainloop & .quit).
-  2. In gui.run, allow any existing interaction to terminate first.
-
-- Change 'The program' to 'Your program' in an IDLE 'kill program?' message

-  To use it with IDLEs released before November 2015, hit the
-  'Save as New Custom Theme' button and enter a new name,
-  such as 'Custom Dark'.  The custom theme will work with any IDLE
-  release, and can be modified.

-
-- Issue #2211: Updated the implementation of the http.cookies.Morsel class.
-  Setting attributes key, value and coded_value directly now is deprecated.
-  update() and setdefault() now transform and check keys.  Comparing for

-  Original patch by Tal Einat.
-
-- Issue #16233: A module browser (File : Class Browser, Alt+C) requires an
-  editor window with a filename.  When Class Browser is requested otherwise,
-  from a shell, output window, or 'Untitled' editor, Idle no longer displays
-  an error box.  It now pops up an Open Module box (Alt+M). If a valid name
-  is entered and a module is opened, a corresponding browser is also opened.
-
-- Issue #4832: Save As to type Python files automatically adds .py to the
-  name you enter (even if your system does not display it).  Some systems

-Build
------
-

-  script.
-
-- Issue #22935: Allow the ssl module to be compiled if openssl doesn't support
-  SSL 3.
-
-- Issue #22592: Drop support of the Borland C compiler to build Python. The
-  distutils module still supports it to build extensions.
-
-- Issue #22591: Drop support of MS-DOS, especially of the DJGPP compiler
-  (MS-DOS port of GCC).
-
-- Issue #16537: Check whether self.extensions is empty in setup.py. Patch by

-
-- Issue #18093: the programs that embed the CPython runtime are now in a
-  separate "Programs" directory, rather than being kept in the Modules
-  directory.
-
-- Issue #15759: "make suspicious", "make linkcheck" and "make doctest" in Doc/
-  now display special message when and only when there are failures.
-
-- Issue #21141: The Windows build process no longer attempts to find Perl,
-  instead relying on OpenSSL source being configured and ready to build.  The
-  ``PCbuild\build_ssl.py`` script has been re-written and re-named to
-  ``PCbuild\prepare_ssl.py``, and takes care of configuring OpenSSL source
-  for both 32 and 64 bit platforms.  OpenSSL sources obtained from
-  svn.python.org will always be pre-configured and ready to build.
-
-- Issue #21037: Add a build option to enable AddressSanitizer support.
-
-- Issue #19962: The Windows build process now creates "python.bat" in the
-  root of the source tree, which passes all arguments through to the most
-  recently built interpreter.
-
-- Issue #21285: Refactor and fix curses configure check to always search
-  in a ncursesw directory.
-
-- Issue #15234: For BerkelyDB and Sqlite, only add the found library and
-  include directories if they aren't already being searched. This avoids
-  an explicit runtime library dependency.
-
-- Issue #17861: Tools/scripts/generate_opcode_h.py automatically regenerates
-  Include/opcode.h from Lib/opcode.py if the latter gets any change.
-

-
-C API
------
-
-- Issue #14203: Remove obsolete support for view==NULL in PyBuffer_FillInfo(),
-  bytearray_getbuffer(), bytesiobuf_getbuffer() and array_buffer_getbuf().
-  All functions now raise BufferError in that case.
-
-- Issue #22445: PyBuffer_IsContiguous() now implements precise contiguity
-  tests, compatible with NumPy's NPY_RELAXED_STRIDES_CHECKING compilation
-  flag.  Previously the function reported false negatives for corner cases.
-
-- Issue #22079: PyType_Ready() now checks that statically allocated type has
-  no dynamically allocated bases.
-
-- Issue #22453: Removed non-documented macro PyObject_REPR().
-
-- Issue #18395: Rename ``_Py_char2wchar()`` to :c:func:`Py_DecodeLocale`,
-  rename ``_Py_wchar2char()`` to :c:func:`Py_EncodeLocale`, and document
-  these functions.
-
-- Issue #21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(),
-  PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) is now using
-  ``calloc()`` instead of ``malloc()`` for large objects which is faster and
-  use less memory.
-
-- Issue #20942: PyImport_ImportFrozenModuleObject() no longer sets __file__ to
-  match what importlib does; this affects _frozen_importlib as well as any
-  module loaded using imp.init_frozen().
-
-Documentation
--------------
-
-- Issue #19548: Update the codecs module documentation to better cover the
-  distinction between text encodings and other codecs, together with other
-  clarifications. Patch by Martin Panter.

-
-- Issue #17386: Expanded functionality of the ``Doc/make.bat`` script to make

-  mention the ability to load the OS certificates.
-
-- Issue #20765: Add missing documentation for PurePath.with_name() and
-  PurePath.with_suffix().
-
-- Issue #19407: New package installation and distribution guides based on
-  the Python Packaging Authority tools. Existing guides have been retained
-  as legacy links from the distutils docs, as they still contain some
-  required reference material for tool developers that isn't recorded
-  anywhere else.
-
-- Issue #19697: Document cases where __main__.__spec__ is None.
-

-
-- asyncio: Refactoring and fixes: BaseEventLoop.sock_connect() raises an
-  error if the address is not resolved; use __slots__ in Handle and
-  TimerHandle; as_completed() and wait() raise TypeError if the passed
-  list of Futures is a single Future; call_soon() and other 'call_*()'
-  functions raise TypeError if the passed callback is a coroutine
-  function; _ProactorBasePipeTransport uses _FlowControlMixin;

-What's New in Python 3.4.0 release candidate 1?
-===============================================
-
-Release date: 2014-02-10
-
-Core and Builtins
------------------
-
-- Issue #19255: The builtins module is restored to initial value before
-  cleaning other modules.  The sys and builtins modules are cleaned last.
-
-- Issue #20588: Make Python-ast.c C89 compliant.
-
-- Issue #20437: Fixed 22 potential bugs when deleting object references.
-
-- Issue #20500: Displaying an exception at interpreter shutdown no longer
-  risks triggering an assertion failure in PyObject_Str.
-
-- Issue #20538: UTF-7 incremental decoder produced inconsistent string when
-  input was truncated in BASE64 section.
-
-- Issue #20404: io.TextIOWrapper (and hence the open() builtin) now uses the
-  internal codec marking system added for issue #19619 to throw LookupError
-  for known non-text encodings at stream construction time. The existing
-  output type checks remain in place to deal with unmarked third party
-  codecs.
-
-- Issue #17162: Add PyType_GetSlot.
-
-- Issue #20162: Fix an alignment issue in the siphash24() hash function which
-  caused a crash on PowerPC 64-bit (ppc64).
-
-Library
--------
-
-- Issue #20530: The signatures for slot builtins have been updated
-  to reflect the fact that they only accept positional-only arguments.
-
-- Issue #20517: Functions in the os module that accept two filenames
-  now register both filenames in the exception on failure.
-
-- Issue #20563: The ipaddress module API is now considered stable.
-
-- Issue #14983: email.generator now always adds a line end after each MIME
-  boundary marker, instead of doing so only when there is an epilogue.  This
-  fixes an RFC compliance bug and solves an issue with signed MIME parts.
-
-- Issue #20540: Fix a performance regression (vs. Python 3.2) when layering
-  a multiprocessing Connection over a TCP socket.  For small payloads, Nagle's
-  algorithm would introduce idle delays before the entire transmission of a
-  message.
-
-- Issue #16983: the new email header parsing code will now decode encoded words
-  that are (incorrectly) surrounded by quotes, and register a defect.
-
-- Issue #19772: email.generator no longer mutates the message object when
-  doing a down-transform from 8bit to 7bit CTEs.
-
-- Issue #20536: the statistics module now correctly handle Decimal instances
-  with positive exponents
-
-- Issue #18805: the netmask/hostmask parsing in ipaddress now more reliably
-  filters out illegal values and correctly allows any valid prefix length.
-
-- Issue #20481: For at least Python 3.4, the statistics module will require
-  that all inputs for a single operation be of a single consistent type, or
-  else a mixed of ints and a single other consistent type. This avoids
-  some interoperability issues that arose with the previous approach of
-  coercing to a suitable common type.
-
-- Issue #20478: the statistics module now treats collections.Counter inputs
-  like any other iterable.
-
-- Issue #17369: get_filename was raising an exception if the filename
-  parameter's RFC2231 encoding was broken in certain ways.  This was
-  a regression relative to python2.
-
-- Issue #20013: Some imap servers disconnect if the current mailbox is
-  deleted, and imaplib did not handle that case gracefully.  Now it
-  handles the 'bye' correctly.
-
-- Issue #20531: Revert 3.4 version of fix for #19063, and apply the 3.3
-  version.  That is, do *not* raise an error if unicode is passed to
-  email.message.Message.set_payload.
-
-- Issue #20476: If a non-compat32 policy is used with any of the email parsers,
-  EmailMessage is now used as the factory class.  The factory class should
-  really come from the policy; that will get fixed in 3.5.
-
-- Issue #19920: TarFile.list() no longer fails when outputs a listing
-  containing non-encodable characters.  Based on patch by Vajrasky Kok.
-
-- Issue #20515: Fix NULL pointer dereference introduced by issue #20368.
-
-- Issue #19186: Restore namespacing of expat symbols inside the pyexpat module.
-
-- Issue #20053: ensurepip (and hence venv) are no longer affected by the
-  settings in the default pip configuration file.

-  select.epoll.poll(), selectors.PollSelector.poll() and
-  selectors.EpollSelector.poll(). For example, a timeout of one microsecond
-  (1e-6) is now rounded to one millisecondi (1e-3), instead of being rounded to
-  zero.  However, the granularity property and asyncio's resolution feature
-  were removed again.

-
-Tools/Demos
------------
-
-- Issue #20530: Argument Clinic's signature format has been revised again.
-  The new syntax is highly human readable while still preventing false
-  positives.  The syntax also extends Python syntax to denote "self" and
-  positional-only parameters, allowing inspect.Signature objects to be
-  totally accurate for all supported builtins in Python 3.4.
-
-- Issue #20456: Argument Clinic now observes the C preprocessor conditional
-  compilation statements of the C files it parses.  When a Clinic block is
-  inside a conditional code, it adjusts its output to match, including
-  automatically generating an empty methoddef macro.
-
-- Issue #20456: Cloned functions in Argument Clinic now use the correct
-  name, not the name of the function they were cloned from, for text
-  strings inside generated code.
-
-- Issue #20456: Fixed Argument Clinic's test suite and "--converters" feature.
-
-- Issue #20456: Argument Clinic now allows specifying different names
-  for a parameter in Python and C, using "as" on the parameter line.
-
-- Issue #20326: Argument Clinic now uses a simple, unique signature to
-  annotate text signatures in docstrings, resulting in fewer false
-  positives.  "self" parameters are also explicitly marked, allowing
-  inspect.Signature() to authoritatively detect (and skip) said parameters.
-
-- Issue #20326: Argument Clinic now generates separate checksums for the
-  input and output sections of the block, allowing external tools to verify
-  that the input has not changed (and thus the output is not out-of-date).
-
-Build
------
-
-- Issue #20465: Update SQLite shipped with OS X installer to 3.8.3.
-
-C-API
------
-
-- Issue #20517: Added new functions allowing OSError exceptions to reference
-  two filenames instead of one: PyErr_SetFromErrnoWithFilenameObjects() and
-  PyErr_SetExcFromWindowsErrWithFilenameObjects().
-
-Documentation
--------------
-
-- Issue #20488: Change wording to say importlib is *the* implementation of
-  import instead of just *an* implementation.
-
-- Issue #6386: Clarify in the tutorial that specifying a symlink to execute
-  means the directory containing the executed script and not the symlink is
-  added to sys.path.
-
-
-What's New in Python 3.4.0 Beta 3?
-==================================
-
-Release date: 2014-01-26
-
-Core and Builtins
------------------
-
-- Issue #20189: Four additional builtin types (PyTypeObject,
-  PyMethodDescr_Type, _PyMethodWrapper_Type, and PyWrapperDescr_Type)
-  have been modified to provide introspection information for builtins.
-
-- Issue #17825: Cursor "^" is correctly positioned for SyntaxError and
-  IndentationError.
-
-- Issue #2382: SyntaxError cursor "^" is now written at correct position in most
-  cases when multibyte characters are in line (before "^").  This still not
-  works correctly with wide East Asian characters.
-
-- Issue #18960: The first line of Python script could be executed twice when
-  the source encoding was specified on the second line.  Now the source encoding
-  declaration on the second line isn't effective if the first line contains
-  anything except a comment.  'python -x' works now again with files with the
-  source encoding declarations, and can be used to make Python batch files
-  on Windows.
-

-
-- Issue #20317: ExitStack.__exit__ could create a self-referential loop if an
-  exception raised by a cleanup operation already had its context set

-- Issue #20390: Argument Clinic's "class" directive syntax has been extended
-  with two new required arguments: "typedef" and "type_object".
-
-- Issue #20390: Argument Clinic: If __new__ or __init__ functions didn't use
-  kwargs (or args), the PyArg_NoKeywords (or PyArg_NoPositional) calls
-  generated are only run when the type object is an exact match.
-
-- Issue #20390: Argument Clinic now fails if you have required parameters after
-  optional parameters.
-

-  disallowed values.
-
-- Issue #20189: Argument Clinic now ensures that parser functions for
-  __new__ are always of type newfunc, the type of the tp_new slot.
-  Similarly, parser functions for __init__ are now always of type initproc,

-  3.3, the function did nothing if the key already exists (if the current value
-  is a non-NULL pointer).
-
-- Issue #14432: Remove the thread state field from the frame structure. Fix a
-  crash when a generator is created in a C thread that is destroyed while the
-  generator is still used. The issue was that a generator contains a frame, and
-  the frame kept a reference to the Python state of the destroyed C thread. The
-  crash occurs when a trace function is setup.
-
-- Issue #19576: PyGILState_Ensure() now initializes threads. At startup, Python
-  has no concrete GIL. If PyGILState_Ensure() is called from a new thread for
-  the first time and PyEval_InitThreads() was not called yet, a GIL needs to be
-  created.

-
-- Issue #19734: ensurepip now ignores all pip environment variables to avoid
-  odd behaviour based on user configuration settings
-
-- Fix TypeError on "setup.py upload --show-response".

-
-- Issue #19850: Set SA_RESTART in asyncio when registering a signal
-  handler to limit EINTR occurrences.

-  Original patch by Simon Sapin.
-
-- Issue #19946: multiprocessing now uses runpy to initialize __main__ in
-  child processes when necessary, allowing it to correctly handle scripts
-  without suffixes and submodules that use explicit relative imports or
-  otherwise rely on parent modules being correctly imported prior to
-  execution.
-
-- Issue #19921: When Path.mkdir() is called with parents=True, any missing
-  parent is created with the default permissions, ignoring the mode argument
-  (mimicking the POSIX "mkdir -p" command).
-
-- Issue #19887: Improve the Path.resolve() algorithm to support certain
-  symlink chains.
-
-- Issue #19912: Fixed numerous bugs in ntpath.splitunc().

-  reference cycles between frames and the _Outcome instance.
-
-- Issue #17429: platform.linux_distribution() now decodes files from the UTF-8
-  encoding with the surrogateescape error handler, instead of decoding from the
-  locale encoding in strict mode. It fixes the function on Fedora 19 which is
-  probably the first major distribution release with a non-ASCII name. Patch
-  written by Toshio Kuratomi.
-
-- Issue #19343: Expose FreeBSD-specific APIs in resource module.  Original
-  patch by Koobs.
-
-- Issue #19929: Call os.read with 32768 within subprocess.Popen.communicate

-  EOF, and analogous bug in lzma module.
-
-- Issue #19881: Fix pickling bug where cpickle would emit bad pickle data for
-  large bytes string (i.e., with size greater than 2**32-1).
-
-- Issue #19138: doctest's IGNORE_EXCEPTION_DETAIL now allows a match when
-  no exception detail exists (no colon following the exception's name, or
-  a colon does follow but no text follows the colon).
-
-- Issue #19927: Add __eq__ to path-based loaders in importlib.
-
-- Issue #19827: On UNIX, setblocking() and settimeout() methods of

-What's New in Python 3.4.0 Beta 1?
-==================================
-
-Release date: 2013-11-24
-
-Core and Builtins
------------------
-
-- Use the repr of a module name in more places in import, especially
-  exceptions.
-
-- Issue #19619: str.encode, bytes.decode and bytearray.decode now use an
-  internal API to throw LookupError for known non-text encodings, rather
-  than attempting the encoding or decoding operation and then throwing a
-  TypeError for an unexpected output type. (The latter mechanism remains
-  in place for third party non-text encodings)
-
-- Issue #19183: Implement PEP 456 'secure and interchangeable hash algorithm'.
-  Python now uses SipHash24 on all major platforms.
-
-- Issue #12892: The utf-16* and utf-32* encoders no longer allow surrogate code
-  points (U+D800-U+DFFF) to be encoded.  The utf-32* decoders no longer decode
-  byte sequences that correspond to surrogate code points.  The surrogatepass
-  error handler now works with the utf-16* and utf-32* codecs.  Based on
-  patches by Victor Stinner and Kang-Hao (Kenny) Lu.
-
-- Issue #17806: Added keyword-argument support for "tabsize" to
-  str/bytes.expandtabs().
-
-- Issue #17828: Output type errors in str.encode(), bytes.decode() and
-  bytearray.decode() now direct users to codecs.encode() or codecs.decode()
-  as appropriate.
-
-- Issue #17828: The interpreter now attempts to chain errors that occur in
-  codec processing with a replacement exception of the same type that
-  includes the codec name in the error message. It ensures it only does this
-  when the creation of the replacement exception won't lose any information.
-
-- Issue #19466: Clear the frames of daemon threads earlier during the
-  Python shutdown to call object destructors. So "unclosed file" resource
-  warnings are now correctly emitted for daemon threads.
-
-- Issue #19514: Deduplicate some _Py_IDENTIFIER declarations.
-  Patch by Andrei Dorian Duma.
-
-- Issue #17936: Fix O(n**2) behaviour when adding or removing many subclasses
-  of a given type.
-
-- Issue #19428: zipimport now handles errors when reading truncated or invalid
-  ZIP archive.
-
-- Issue #18408: Add a new PyFrame_FastToLocalsWithError() function to handle
-  exceptions when merging fast locals into f_locals of a frame.
-  PyEval_GetLocals() now raises an exception and return NULL on failure.
-
-- Issue #19369: Optimized the usage of __length_hint__().
-
-- Issue #18603: Ensure that PyOS_mystricmp and PyOS_mystrnicmp are in the
-  Python executable and not removed by the linker's optimizer.
-
-- Issue #19306: Add extra hints to the faulthandler module's stack
-  dumps that these are "upside down".
-
-Library
--------

-  computes the stack effect of bytecode instructions.
-
-- Issue #19735: Implement private function ssl._create_stdlib_context() to
-  create SSLContext objects in Python's stdlib module. It provides a single
-  configuration point and makes use of SSLContext.load_default_certs().
-
-- Issue #16203: Add re.fullmatch() function and regex.fullmatch() method,
-  which anchor the pattern at both ends of the string to match.
-  Original patch by Matthew Barnett.
-
-- Issue #13592: Improved the repr for regular expression pattern objects.
-  Based on patch by Hugo Lopes Tavares.

-  provide the same API elements as non-keyed cryptographic hash functions.
-
-- Issue #17276: MD5 as default digestmod for HMAC is deprecated. The HMAC
-  module supports digestmod names, e.g. hmac.HMAC('sha1').

-What's New in Python 3.4.0 Alpha 4?
-===================================
-
-Release date: 2013-10-20
-
-Core and Builtins
------------------
-
-- Issue #19301: Give classes and functions that are explicitly marked global a
-  global qualname.
-
-- Issue #19279: UTF-7 decoder no longer produces illegal strings.
-
-- Issue #16612: Add "Argument Clinic", a compile-time preprocessor for
-  C files to generate argument parsing code.  (See PEP 436.)
-
-- Issue #18810: Shift stat calls in importlib.machinery.FileFinder such that
-  the code is optimistic that if something exists in a directory named exactly
-  like the possible package being searched for that it's in actuality a
-  directory.
-
-- Issue #18416: importlib.machinery.PathFinder now treats '' as the cwd and
-  importlib.machinery.FileFinder no longer special-cases '' to '.'. This leads
-  to modules imported from cwd to now possess an absolute file path for
-  __file__ (this does not affect modules specified by path on the CLI but it
-  does affect -m/runpy). It also allows FileFinder to be more consistent by not
-  having an edge case.
-
-- Issue #4555: All exported C symbols are now prefixed with either
-  "Py" or "_Py".

-    1. ppc arch detection for extension module builds broke with Xcode 5
-    2. ppc arch detection in configure did not work on OS X 10.4
-    3. -sysroot and -arch flags were unnecessarily duplicated
-    4. there was no obvious way to configure an intel-32 only build.
-
-- Issue #19019: Change the OS X installer build script to use CFLAGS instead
-  of OPT for special build options.  By setting OPT, some compiler-specific
-  options like -fwrapv were overridden and thus not used, which could result
-  in broken interpreters when building with clang.

On Windows, test.support.fd_count() now calls
msvcrt.CrtSetReportMode() to not kill the process nor log any error
on stderr on os.dup(fd) if the file descriptor is invalid.

Don't rely on the current SIGHUP signal handler, make sure that it's
set to the "default" signal handler: SIG_DFL.

summary:

bpo-31019: Fix multiprocessing.Process.is_alive() (#2875)

multiprocessing.Process.is_alive() now removes the process from the
_children set if the process completed.

The change prevents leaking "dangling" processes.

* bpo-31034: Reliable signal handler for test_asyncio

Don't rely on the current SIGHUP signal handler, make sure that it's
set to the "default" signal handler: SIG_DFL.

* Add comments

summary:

[3.6] bpo-26762, bpo-31019: Backport multiprocessing fixes from master to 3.6 (#2879)

* bpo-26762: Avoid daemon process in _test_multiprocessing (#2842)

test_level() of _test_multiprocessing._TestLogging now uses regular
processes rather than daemon processes to prevent zombi processes
(to not "leak" processes).
(cherry picked from commit 06634950c553f8df83330ed468c11483b857b7dc)

* test_multiprocessing: Fix dangling process/thread (#2850)

bpo-26762: Fix more dangling processes and threads in
test_multiprocessing:

* Queue: call close() followed by join_thread()
* Process: call join() or self.addCleanup(p.join)
(cherry picked from commit d7e64d9934d86aa6173229de5af5fe908662a33a)

* test_multiprocessing detects dangling per test case (#2841)

bpo-26762: test_multiprocessing now detects dangling processes and
threads per test case classes:

* setUpClass()/tearDownClass() of mixin classes now check if
  multiprocessing.process._dangling or threading._dangling was
  modified to detect "dangling" processses and threads.
* ManagerMixin.tearDownClass() now also emits a warning if it still
  has more than one active child process after 5 seconds.
* tearDownModule() now checks for dangling processes and threads
  before sleep 500 ms. And it now only sleeps if there is a least one
  dangling process or thread.
(cherry picked from commit ffb49408f0780ae80a553208aa133bc5bb3ba129)

* bpo-26762: test_multiprocessing close more queues (#2855)

* Close explicitly queues to make sure that we don't leave dangling
  threads
* test_queue_in_process(): remove unused queue
* test_access() joins also the process to fix a random warning
(cherry picked from commit b4c52966c810b5c5e088fceff403247f610b7d13)

* bpo-31019: Fix multiprocessing.Process.is_alive() (#2875)

multiprocessing.Process.is_alive() now removes the process from the
_children set if the process completed.

The change prevents leaking "dangling" processes.
(cherry picked from commit 2db64823c20538a6cfc6033661fab5711d2d4585)

summary:

bpo-30845: Enhance test_concurrent_futures cleanup (#2564) (#2880)

* bpo-30845: reap_children() now logs warnings

* bpo-30845: Enhance test_concurrent_futures cleanup

In setUp() and tearDown() methods of test_concurrent_futures tests,
make sure that tests don't leak threads nor processes. Clear
explicitly the reference to the executor to make it that it's
destroyed (to prevent "dangling threads" warning).

* bpo-30595: Fix multiprocessing.Queue.get(timeout) (#2027)

multiprocessing.Queue.get() with a timeout now polls its reader in
non-blocking mode if it succeeded to aquire the lock but the acquire
took longer than the timeout.

Co-Authored-By: Grzegorz Grzywacz <grzgrzgrz3 at gmail.com>
(cherry picked from commit 1b7863c3b6519c6e134c28cab8b8af0dea43e375)

* bpo-30595: Increase test_queue_feeder_donot_stop_onexc() timeout (#2148)

_test_multiprocessing.test_queue_feeder_donot_stop_onexc() now uses a
timeout of 1 second on Queue.get(), instead of 0.1 second, for slow
buildbots.

* bpo-30595: Fix multiprocessing.Queue.get(timeout) (#2027)

multiprocessing.Queue.get() with a timeout now polls its reader in
non-blocking mode if it succeeded to aquire the lock but the acquire
took longer than the timeout.

Co-Authored-By: Grzegorz Grzywacz <grzgrzgrz3 at gmail.com>

* bpo-30595: Increase test_queue_feeder_donot_stop_onexc() timeout (#2148)

_test_multiprocessing.test_queue_feeder_donot_stop_onexc() now uses a
timeout of 1 second on Queue.get(), instead of 0.1 second, for slow
buildbots.

multiprocessing.Process.is_alive() now removes the process from the
_children set if the process completed.

The change prevents leaking "dangling" processes.

bpo-30980: Fix double close in asyncore.file_wrapper (#2789) (#2900)

* bpo-30980: Fix close test to fail

test_close_twice was not considering the fact that file_wrapper is
duping the file descriptor. Closing the original descriptor left the
duped one open, hiding the fact that close protection is not effective.

* bpo-30980: Fix double close protection

Invalidated self.fd before closing, handling correctly the case when
os.close raises.

* bpo-30980: Fix fd leak introduced in the fixed test

summary:

bpo-31003: IDLE - Add more tests for General tab (#2859)

* 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.

     self.result - return or raise value set in __init__.
+    self.return_self - return self instead, to mock query class return.
 
     Most common use will probably be to mock instance methods.
     Given class instance, can set and delete as instance attribute.
     Mock_tk.Var and Mbox_func are special variants of this.

summary:

[3.6] bpo-31003: IDLE - Add more tests for General tab (GH-2859) (#2906)

* 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.
(cherry picked from commit 2bc8f0e)

summary:

bpo-31060: IDLE: Finish regrouping ConfigDialog methods (#2908)

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.

summary:

[3.6] bpo-31060: IDLE: Finish regrouping ConfigDialog methods (GH-2908) (#2925)

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.
(cherry picked from commit b166080)

summary:

bpo-30781: IDLE - Use ttk Notebook in ConfigDialog (#2938)

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.

+IDLE - Use ttk Notebook in ConfigDialog


From webhook-mailer at python.org  Sat Jul 29 01:28:08 2017

Subject: [Python-checkins] [3.6] bpo-30781: IDLE - Use ttk Notebook in
 ConfigDialog (GH-2938) (#2944)
Message-ID: <mailman.90.1501306093.3033.python-checkins@python.org>

https://github.com/python/cpython/commit/8364feff6730f54063116b607605167d9027ce85
commit: 8364feff6730f54063116b607605167d9027ce85
branch: 3.6
author: Terry Jan Reedy <tjreedy at udel.edu>

summary:

[3.6] bpo-30781: IDLE - Use ttk Notebook in ConfigDialog (GH-2938) (#2944)

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.
(cherry picked from commit b331f80)

+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.

+        name, position pairs and copies names to listbox helplist.
+        Clicking a name invokes help_source selected. Clicking
+        button_helplist_name invokes helplist_item_name, which also
+        changes user_helplist.  These functions all call
+        set_add_delete_state. All but load call update_help_changes to

bpo-31091: Remove dead code in PyErr_GivenExceptionMatches(). (#2963)
