* bpo-37742: Return the root logger when logging.getLogger('root') is called.
* Added type check guard on logger name in logging.getLogger() and refined a test.
Fixed QueueListener in order to avoid random deadlocks.
Unable to add regression tests atm due to time constraints, will add it in a bit.
Regarding implementation, although it's nested, it does not cause performance issues whatsoever, and does not call task_done() in case of an exception (which is the right thing to do IMHO).

Instead of attempting to acquire and release them all across fork
which was leading to deadlocks in some applications that had chained
their own handlers while holding multiple locks.
When runnint test_logging with --huntrleaks after commit
18fb1fb943, test_out_of_order fails
to raise ValueError due to the fact that the new test
test_out_of_order_with_dollar_style mutates the out_of_order
dictionary. Even if the test copies the dictionary first, the mutation
is done in a very deep level so the original one is also affected.
bpo-6721: When os.fork() was called while another thread holds a logging lock, the child process may deadlock when it tries to log. This fixes that by acquiring all logging locks before fork and releasing them afterwards.
A regression test that fails before this change is included.
Within the new unittest itself: There is a small _potential_ due to mixing of fork and a thread in the child process if the parent's thread happened to hold a non-reentrant library call lock (malloc?) when the os.fork() happens. buildbots and time will tell if this actually manifests itself in this test or not. :/ A functionality test that avoids that would be a challenge.
An alternate test that isn't trying to produce the deadlock itself but just checking that the release and acquire calls are made would be the next best alternative if so.
A check has been added in Logger.isEnabledFor() to return False when the logger is disabled. This avoids unnecessary work being done when a disabled logger is used.
* Fix multiple typos in code comments
* Add spacing in comments (test_logging.py, test_math.py)
* Fix spaces at the beginning of comments in test_logging.py
This used to be the case on Python 2. Commit
212b590e11 changed the implementation for Python
3, making the `log()` method of LogAdapter call `logger._log()` directly. This
makes nested log adapters not execute their ``process()`` method. This patch
fixes the issue.
Also, now proxying `name`, too, to make `repr()` work with nested log adapters.
New tests added.
Some of the proxied methods use internal Logger state which isn't proxied,
causing failures if an adapter is applied to another adapter.
This commit fixes the issue, adds a new test for the use case.
socketserver.ThreadingMixIn now keeps a list of non-daemonic threads
to wait until all these threads complete in server_close().
Reenable test_logging skipped tests.
Fix SocketHandlerTest.tearDown(): close the socket handler before
stopping the server, so the server can join threads.
* bpo-30830: test_logging uses threading_setup/cleanup
Replace @support.reap_threads on some methods with
support.threading_setup() in setUp() and support.threading_cleanup()
in tearDown() in BaseTest.
* bpo-30830: test_logging disables threaded socketserver tests
Disable tests because of socketserver.ThreadingMixIn leaks threads,
whereas leaking threads now makes a test to fail on buildbots.
Disable tests until socketserver is fixed: bpo-31233.
* Skip also setup_via_listener()
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).
