test_builtin.PtyTests now registers an handler for SIGHUP signal.
Closing the PTY file descriptor can emit a SIGHUP signal: just ignore
it.
run_child() now also closes the PTY file descriptor before waiting
for the process completition, otherwise the test hangs on AIX.
There are two copies of the grammar -- the one used by Python itself as
Grammar/Grammar, and the one used by lib2to3 which has necessarily diverged at
Lib/lib2to3/Grammar.txt because it needs to support older syntax an we want it
to be reasonable stable to avoid requiring fixer rewrites.
This brings suport for syntax like `if x:= foo():` to match what the live
Python grammar does.
This should've been added at the time of the walrus operator itself, but lib2to3 being
independent is often overlooked. So we do consider this a bugfix rather than enhancement.
CGIHTTPRequestHandler of http.server now logs the CGI script exit
code, rather than the CGI script exit status of os.waitpid().
For example, if the script is killed by signal 11, it now logs:
"CGI script exit code -11."
The AbstractBasicAuthHandler class of the urllib.request module uses
an inefficient regular expression which can be exploited by an
attacker to cause a denial of service. Fix the regex to prevent the
catastrophic backtracking. Vulnerability reported by Ben Caller
and Matt Schwager.
AbstractBasicAuthHandler of urllib.request now parses all
WWW-Authenticate HTTP headers and accepts multiple challenges per
header: use the realm of the first Basic challenge.

Add os.waitstatus_to_exitcode() function to convert a wait status to an
exitcode.
Suggest waitstatus_to_exitcode() usage in the documentation when
appropriate.
Use waitstatus_to_exitcode() in:
* multiprocessing, os, subprocess and _bootsubprocess modules;
* test.support.wait_process();
* setup.py: run_command();
* and many tests.
Running `test_socket` or anything that depends on it (like python -m
test.pythoninfo) crashes if IOCTL_VM_SOCKETS_GET_LOCAL_CID does not
exist in the socket module.

* Add _waitstatus_to_exitcode() helper function to _bootsubprocess.
* Enhance check_output() error message if the command fails.
_bootsubprocess no longer handles WIFSTOPPED() case: it now raises a
ValueError.
* Rewrite test_thread.test_forkinthread() to use
support.wait_process() and wait for the child process in the main
thread, not in the spawned thread.
* test_threading now uses support.wait_process() and checks the child
process exit code to detect crashes.
* test_fork1: remove duplicated wait_impl() method: reuse
fork_wait.py implementation instead.
* Use exit code different than 0 to ensure that we executed the
expected code path.
Moreover, the following tests now check the child process exit code:
* test_os.PtyTests
* test_mailbox.test_lock_conflict()
* test_tempfile.test_process_awareness()
* test_uuid.testIssue8621()
* multiprocessing resource tracker tests
Replace statically allocated types with heap allocated types:
use PyType_FromSpec().
Add a module state to store the _abc_data_type.
Add traverse, clear and free functions to the module.
Change 0/1 assignments to 'executing', 'canceled', 'reading', 'endoffile'.
These are not used outside of pyshell. Other bools already use False/True.
Add comment about int needed for Windows call.
Remove self.more, unused in idlelib and code.InteractiveInterpreter.
The latter uses 'more' as a local.
Remove daemon threads from :mod:`concurrent.futures` by adding
an internal `threading._register_atexit()`, which calls registered functions
prior to joining all non-daemon threads. This allows for compatibility
with subinterpreters, which don't support daemon threads.
If fork was not called by a thread spawned by threading.Thread,
threading._after_fork() now creates a _MainThread instance for
_main_thread, instead of a _DummyThread instance.
This pull request fixes the newline conversion bug originally reported in bpo-1812. When that issue was originally submitted, the open builtin did not default to universal newline mode; now it does, which makes the issue fix simpler, since the only code path that needs to be changed is the one in doctest._load_testfile where the file is loaded from a package whose loader has a get_data method.
Remove two unused imports: _thread and _weakref. Avoid creating a new
winreg builtin module if it's already available in sys.modules.
The winreg module is now stored as "winreg" rather than "_winreg".
PyThreadState.frame is a borrowed reference, not a strong reference:
PyThreadState_Clear() must not call Py_CLEAR(tstate->frame).
Remove test_threading.test_warnings_at_exit(): we cannot warranty
that the Python thread state of daemon threads is cleared in a
reliable way during Python shutdown.
* Update ChainMap to include | and |=
Created __ior__, __or__ and __ror__ methods in ChainMap class.
* Update ACKS
* Update docs
* Update test_collections.py to include test_issue584().
Added testing for | and |= operators for ChainMap objects.
* Update test_union_operators
Renamed test_union operators, fixed errors and style problems raised by brandtbucher.
* Update test_union_operators in TestChainMap
Added testing for union operator between ChainMap and iterable of key-value pairs.
* Update test_union operators in test_collections.py
Gave more descriptive variable names and eliminated unnecessary tmp variable.
* Update test_union_operators in test_collections.py
Added cm3
* Check .maps rather than Chainmap equality.
* Add news entry
* Update Lib/test/test_collections.py

* Re-add removed classes Suite, slice, Param, AugLoad and AugStore.
* Add docstrings for dummy classes.
* Add docstrings for attribute aliases.
* Set __module__ to "ast" instead of "_ast".
* bpo-22490: Remove "__PYVENV_LAUNCHER__" from the shell environment on macOS
This changeset removes the environment varialbe "__PYVENV_LAUNCHER__"
during interpreter launch as it is only needed to communicate between
the stub executable in framework installs and the actual interpreter.
Leaving the environment variable present may lead to misbehaviour when
launching other scripts.
* Actually commit the changes for issue 22490...
* Correct typo
