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
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)...').
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).
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.
Compiled regular expression objects with the re.LOCALE flag no longer
depend on the locale at compile time. Only the locale at matching
time affects the result of matching.
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.
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>}
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().
Move also tearDown() just after setUp().
* #30190 / unittest / assertAlmostEqual(delta=...) / error msg: show the difference between the 2 numbers in case of failure
* safe_repr() diff
* also show difference when passing 'places' argument
* refactoring
* update Misc/NEWS
* bpo-30197: Enhance functions swap_attr() and swap_item() in test.support.
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.
* Update docstrings.
* 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.
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).
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
At the time when an abstract base class' __init_subclass__ runs,
ABCMeta.__new__ has not yet finished running, so in the presence of
__init_subclass__, inspect.isabstract() can no longer depend only on
TPFLAGS_IS_ABSTRACT.
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.
* bpo-30125: Cleanup faulthandler.c
* Use size_t type for iterators
* Add { ... }
* bpo-30125: Fix faulthandler.disable() on Windows
On Windows, faulthandler.disable() now removes the exception handler
installed by faulthandler.enable().
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']
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.
The @reap_threads decorator and the threading_cleanup() function of
test.support now log a warning if they fail to clenaup threads.
Fix also the usage of support.threading_cleanup() in
test_urllib2_localnet.
The log may help to debug such other warning seen on the AMD64
FreeBSD CURRENT Non-Debug 3.x buildbot:
Warning -- threading._dangling was modified by test_logging
