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
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.
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().
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.
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-29514: Check magic number for micro release
Add a dict importlib.util.EXPECTED_MAGIC_NUMBERS which
details the initial and expected pyc magic number for
each minor release. This gives a mechanism for users to
check if the magic number has changed within a release and
for a test to ensure procedure is followed if a change is
necessary.
Add a test to check the current MAGIC_NUMBER against the
expected number for the release if the current release is
at candidate or final level. On test failure, describe to
the developer the procedure for changing the magic number.
* Simplify magic number release test
Simplify the magic number release test by removing
EXPECTED_MAGIC_NUMBERS table and making the expected
magic number self-contained within the test.
BPO: 29514
* Improve magic number test execution and message
Improve the execution of the magic number test by
using skipUnless for alpha and beta releases, and
directly inheriting from unittest.TestCase rather than
using the machinery for the other tests. Also improve
the error message to explain the reason for caution in
changing the magic number.
BPO: 29514
* 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.
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.
conn.set_trace_callback() shouldn't be called multiple times when the
schema is changing.
This has indirectly been fixed by using sqlite3_prepare_v2() in bpo-9303.
* Implement math.remainder.
* Fix markup for arguments; use double spaces after period.
* Mark up function reference in what's new entry.
* Add comment explaining the calculation in the final branch.
* Fix out-of-order entry in whatsnew.
* Add comment explaining why it's good enough to compare m with c, in spite of possible rounding error.
* bpo-29972: Fix test_eintr on AIX
On AIX, sigtimedwait(0.2) sleeps 199.8 ms, whereas the test expects
200 ms or longer.
* bpo-29972: Skip some inet_pton() tests on AIX
Skip some inet_pton() tests of test_socket on AIX.
inet_pton() on AIX is less strict than on Linux and doesn't reject
some invalid IP addresses. The unit tests test more the libc than
Python itself.
* bpo-29972: Skip tests known to fail on AIX
* test_locale.test_strcoll_with_diacritic()
* test_locale.test_strxfrm_with_diacritic()
* test_strptime.test_week_of_year_and_day_of_week_calculation()
* test_tools.test_POT_Creation_Date()
* change LBYL key lookup to dict.setdefault
The ``results`` was constructed as a defaultdict and we could simply
delete the check ``if key not in results``. However, I think it's safer
to use dict.setdefault as I'm not sure whether the caller expects a
regular dict or defaultdict.
* add name to the acknowledgements file
* use defaultdict to make the key-lookup cleaner
the original logic was just comparing the network address
but this is wrong because if the network address is equal then
we need to compare the ip address for breaking the tie
add more ip_interface comparison tests
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.
Element.getiterator() and the html parameter of XMLParser() were
deprecated only in the documentation (since Python 3.2 and 3.4 correspondintly).
Now using them emits a deprecation warning.
* Don’t need check_warnings any more.
* test_normalization fails if download fails
bpo-29887. The test is still skipped if "-u urlfetch" option is not
passed to regrtest (python3 -m test -u urlfetch test_normalization).
* Fix ResourceWarning in test_normalization
bpo-29887: Fix ResourceWarning in test_normalization if tests are
interrupted by CTRL+c.
Add the 'monetary' parameter to format_string so that all
uses of format can be converted to format_string. Adjust
the documentation accordingly, and add a deprecation
warning when format is used.
