The slightly modified tests continue to pass. The General test
broken by the switch to Notebook is fixed.
Patch mostly by Cheryl Sabella.
(cherry picked from commit 9397e2a)
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.

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.

When running the test suite using --use=all / -u all, exclude tzdata

-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.

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.

(cherry picked from commit 57161aac5e)
If we have a chain of generators/coroutines that are 'yield from'ing
each other, then resuming the stack works like:
- call send() on the outermost generator
- this enters _PyEval_EvalFrameDefault, which re-executes the
YIELD_FROM opcode
- which calls send() on the next generator
- which enters _PyEval_EvalFrameDefault, which re-executes the
YIELD_FROM opcode
- ...etc.
However, every time we enter _PyEval_EvalFrameDefault, the first thing
we do is to check for pending signals, and if there are any then we
run the signal handler. And if it raises an exception, then we
immediately propagate that exception *instead* of starting to execute
bytecode. This means that e.g. a SIGINT at the wrong moment can "break
the chain" – it can be raised in the middle of our yield from chain,
with the bottom part of the stack abandoned for the garbage collector.
The fix is pretty simple: there's already a special case in
_PyEval_EvalFrameEx where it skips running signal handlers if the next
opcode is SETUP_FINALLY. (I don't see how this accomplishes anything
useful, but that's another story.) If we extend this check to also
skip running signal handlers when the next opcode is YIELD_FROM, then
that closes the hole – now the exception can only be raised at the
innermost stack frame.
This shouldn't have any performance implications, because the opcode
check happens inside the "slow path" after we've already determined
that there's a pending signal or something similar for us to process;
the vast majority of the time this isn't true and the new check
doesn't run at all..

to the line in the user code. Previously they could point into inners
of the re module if emitted from inside of groups or conditionals..

* python-gdb.py supports method-wrapper
bpo-29367: python-gdb.py now supports also method-wrapper (wrapperobject)
objects.

* Update and enhance python-gdb.py
bpo-29259: Detect PyCFunction is the current frame, not only in the
older frame.
when there are no more `await` or `yield (from)` before return in coroutine,
cancel was ignored.
example:
async def coro():
asyncio.Task.current_task().cancel()
return 42
...
res = await coro() # should raise CancelledError
(cherry picked from commit 991adca012)
Rewrite sigwaitinfo() and sigtimedwait() unit tests for EINTR using
pthread_sigmask() to fix a race condition between the child and the
parent process.
Remove the pipe which was used as a weak workaround against the race
condition.
sigtimedwait() is now tested with a child process sending a signal
instead of testing the timeout feature which is more unstable
(especially regarding to clock resolution depending on the platform).
(cherry picked from commit 211a392cc1)
Now allowed several subsequential inline modifiers at the start of the
pattern (e.g. '(?i)(?s)...'). In verbose mode whitespaces and comments
now are allowed before and between inline modifiers (e.g.
'(?x) (?i) (?s)...')..
(cherry picked from commit 305ccbe27e)
ExpatParser.parse() of xml.sax.xmlreader now always closes the
source: close the file object or the urllib object if source is a
string (not an open file-like object). The change fixes a
ResourceWarning on parsing error.
Add test_parse_close_source() unit test.

* bpo-23404: make touch becomes make regen-all (#1405)
Don't rebuild generated files based on file modification time
anymore, the action is now explicit. Replace "make touch"
with "make regen-all".
Changes:
* Remove "make touch", Tools/hg/hgtouch.py and .hgtouch
* Add a new "make regen-all" command to rebuild all generated files
* Add subcommands to only generate specific files:
- regen-ast: Include/Python-ast.h and Python/Python-ast.c
- regen-grammar: Include/graminit.h and Python/graminit.c
- regen-importlib: Python/importlib_external.h and Python/importlib.h
- regen-opcode: Include/opcode.h
- regen-opcode-targets: Python/opcode_targets.h
- regen-typeslots: Objects/typeslots.inc
* Rename PYTHON_FOR_GEN to PYTHON_FOR_REGEN
* pgen is now only built by by "make regen-grammar"
* Add $(srcdir)/ prefix to paths to source files to handle correctly
compilation outside the source directory
Note: $(PYTHON_FOR_REGEN) is no more used nor needed by "make"
default target building Python.
(cherry picked from commit a5c62a8e9f)
* bpo-30273: Update sysconfig (#1464)
The AST_H_DIR variable was removed from Makefile.pre.in by the commit
a5c62a8e9f (bpo-23404).
AST_H_DIR was hardcoded to "Include", so replace the removed variable
by its content.
Remove also ASDLGEN variable from sysconfig example since this
variable was also removed.
(cherry picked from commit b109a1d336)
Buildbots don't run tests with -vv and so only log "xxx was modified
by test_xxx" which is not enough to debug such random issue. In many
cases, I'm unable to reproduce the warning and so unable to fix it.
Always logging the value before and value after should help to debug
such warning on buildbots.
(cherry picked from commit ec4b17239d)
AsyncoreEchoServer of test_ssl now calls
asyncore.close_all(ignore_all=True) to ensure that
asyncore.socket_map is cleared once the test completes, even if
ConnectionHandler was not correctly unregistered.
Fix the following warning:
Warning -- asyncore.socket_map was modified by test_ssl
Before: {}
After: {6: <test.test_ssl.AsyncoreEchoServer.EchoServer.ConnectionHandler>}
(cherry picked from commit 1dae7450c6)
BuildExtTestCase of test_distutils now uses support.temp_cwd() in
setUp() to remove files created in the current working in all
BuildExtTestCase unit tests, not only test_build_ext().
Fix the following warning:
Warning -- files was modified by test_distutils
Before: []
After: ['vc140.pdb']
Add setUpModule() and tearDownModule() functions to test_site to
save/restore sys.path at the module level to prevent warning if the
user site directory is created, since site.addsitedir() modifies
sys.path.
(cherry picked from commit b85c136903)
They now work when delete replaced attribute or item inside the with
statement. The old value of the attribute or item (or None if it doesn't
exist) now will be assigned to the target of the "as" clause, if there is
one.
(cherry picked from commit d1a1def7bf)
Disable faulthandler to run test_SEH() of test_ctypes to prevent the
following log with a traceback:
Windows fatal exception: access violation
Add support.disable_faulthandler() context manager.
(cherry picked from commit a36e939aeb)
QueueListenerTest of test_logging now closes the multiprocessing
Queue and joins its thread to prevent leaking dangling threads to
following tests.
Add also @support.reap_threads to detect earlier if a test leaks
threads (and try to "cleanup" these threads).
(cherry picked from commit 8ca2f2faef)
* Fix/optimize test_asyncore.test_quick_connect() (#1188)
Don't use addCleanup() in test_quick_connect() because it keeps the
Thread object alive and so @reap_threads fails on its timeout of 1
second. "./python -m test -v test_asyncore -m test_quick_connect"
now takes 185 ms, instead of 11 seconds.
Other minor changes:
* Use "with sock:" to close the socket instead of
try/finally: sock.close()
* Use self.skipTest() in test_quick_connect() to remove one
indentation level and notice user that the test is specific to
AF_INET and AF_INET6
* bpo-30106: Fix tearDown() of test_asyncore (#1194)
Call asyncore.close_all() with ignore_all=True in the tearDown()
method of the test_asyncore base test case. It should prevent keeping
alive sockets in asyncore.socket_map if close() fails with an
unexpected error.
Revert also an unwanted change of my previous commit: remove name
parameter of Thread in test_quick_connect().
* bpo-30106: Fix test_asyncore.test_quick_connect() (#1234)
test_quick_connect() runs a thread up to 50 seconds, whereas the
socket is connected in 0.2 second and then the thread is expected to
end in less than 3 second. On Linux, the thread ends quickly because
select() seems to always return quickly. On FreeBSD, sometimes
select() fails with timeout and so the thread runs much longer than
expected.
Fix the thread timeout to fix a race condition in the test.
On macOS, SuppressCrashReport now redirects /usr/bin/defaults command
stderr into a pipe to not pollute stderr. It fixes a
test_io.test_daemon_threads_shutdown_stderr_deadlock() failure when
the CrashReporter domain doesn't exists. Message logged into stderr:
2017-04-24 16:57:21.432 defaults[41046:2462851]
The domain/default pair of (com.apple.CrashReporter, DialogType) does not exist
(cherry picked from commit d819ad9832)
* bpo-30175: Skip client cert tests of test_imaplib
The IMAP server cyrus.andrew.cmu.edu doesn't accept our randomly
generated client x509 certificate anymore.
* bpo-30188: Catch EOFError in NetworkedNNTPTests
test_nntplib fails randomly with EOFError in
NetworkedNNTPTests.setUpClass(). Catch EOFError to skip tests in that
case.
(cherry picked from commit 5bccca58b9)
test_io has two unit tests which trigger a deadlock:
* test_daemon_threads_shutdown_stdout_deadlock()
* test_daemon_threads_shutdown_stderr_deadlock()
These tests call Py_FatalError() if the expected bug is triggered
which calls abort(). Use test.support.SuppressCrashReport to prevent
the creation on a core dump, to fix the warning:
Warning -- files was modified by test_io
Before: []
After: ['python.core']
(cherry picked from commit 2a1aed04b0)
* Allow underscores in numeric literals in lib2to3.
* Stricter literal parsing for Python 3.6 in lib2to3.pgen2.tokenize.
* Add test case for underscores in literals in Python 3.
(cherry picked from commit a6e395dffa)
contextlib._GeneratorContextManager.__exit__ includes a special case to deal with
PEP 479 RuntimeErrors created when `StopIteration` is thrown into the context
manager body.
Previously this check was too permissive, and undid one level of chaining on *all*
RuntimeError instances, not just those that wrapped a StopIteration instance.
(cherry picked from commit 00c75e9a45)
* bpo-29942: Fix the use of recursion in itertools.chain.from_iterable.
Fix the use of recursion in itertools.chain.from_iterable. Using recursion
is unnecessary, and can easily cause stack overflows, especially when
building in low optimization modes or with Py_DEBUG enabled.
(cherry picked from commit 5466d4af5f)
* bpo-29861: release references to multiprocessing Pool tasks (#743)
* bpo-29861: release references to multiprocessing Pool tasks
Release references to tasks, their arguments and their results as soon
as they are finished, instead of keeping them alive until another task
arrives.
* Comments in test
(cherry picked from commit 8988945cdc)
* Fix Misc/NEWS (hopefully)
Directory and zipfile execution previously added
the parent directory of the directory or zipfile
as sys.path[0] and then subsequently overwrote
it with the directory or zipfile itself.
This caused problems in isolated mode, as it
overwrote the "stdlib as a zip archive" entry
in sys.path, as the parent directory was
never added.
The attempted fix to that issue in bpo-29319
created the opposite problem in *non*-isolated
mode, by potentially leaving the parent
directory on sys.path instead of overwriting it.
This change fixes the root cause of the problem
by removing the whole "add-and-overwrite" dance
for sys.path[0], and instead simply never adds
the parent directory to sys.path in the first
place.
(cherry picked from commit d2977a3ae2)
Skip some tests of select.poll when running on macOS due to unresolved
issues with the underlying system poll function on some macOS versions.
(cherry picked from commit de04644627)
* bpo-27593: Get SCM build info from git instead of hg. (#446)
sys.version and the platform module python_build(),
python_branch(), and python_revision() functions now use
git information rather than hg when building from a repo.
Based on original patches by Brett Cannon and Steve Dower.
(cherry picked from commit 5c4b0d063a)
Allow developers to not have to either test on N Python versions or
looked through multiple versions of the docs to know whether they can
easily update.
(cherry picked from commit c643a967dd)
Clarify that methods take a string which is interpreted as a regex,
not a regex object.
Also clarify what the old `-1`, `0`, `1` and `2` options were.
(cherry picked from commit 8fb1f6e039)
``local.getlocale(locale.LC_CTYPE)`` and
``locale.getpreferredencoding(False)`` may give different answers
in some cases (such as the ``en_IN`` locale).
``re.LOCALE`` uses the latter, so update the test case to match.
It took me quite a bit to figure out what this was referring to,
since the given issue number is wrong, and the original commit
message I found through git blame lists a different, also wrong
issue number... see https://bugs.python.org/issue27122#msg279449
(cherry picked from commit af88e7eda4)
The “readline” module already has a workaround using setlocale(LC_CTYPE,
NULL). The code in test___all__ calls getlocale(), which can subtly alter
the locale string and cause the test framework to complain.
