bpo-38203: faulthandler.dump_traceback_later() is always available (GH-16249)
dump_traceback_later() and cancel_dump_traceback_later() functions of
the faulthandler module are always available since Python 3.7.

Michael Felt b94d4bed67 bpo-35633: test_lockf() fails with "PermissionError: [Errno 13] Permission denied" on AIX (GH-11424)
[bpo-35633](https://bugs.python.org/issue35633): Fix a test regression introduced with [bpo-35189](https://bugs.python.org/issue35189) (PEP 475: fnctl functions are not retried if interrupted (EINTR)).

Not only a blocking IO error needs to be ignored - permission errors also need to be ignored.

p.s. - iirc as a "test" only correction a NEWS item is not required. If this is not correct - just mention, and I'll add a NEWS blurb.

nierob b409ffa848 bpo-35189: Retry fnctl calls on EINTR (GH-10413)

(EINTR): flock, lockf, fnctl.

bpo-35189: Fix eintr_tester.py (GH-10637)
Call setitimer() before each test method, instead of once per test
case, to ensure that signals are sent in each test method.
Previously, only the first method of a testcase class got signals.

Changes:

* Replace setUpClass() with setUp() and replace tearDownClass() with
  tearDown().
* tearDown() now ensures that at least one signal has been sent.
* Replace support.run_unittest() with unittest.main() which has
  a nicer CLI and automatically discover test cases.

bpo-28759: Skip some tests on PermissionError raised by Android (GH-4350)
Access to mkfifo(), mknod() and hard link creation is controled
by SELinux on Android.
Also remove test.support.android_not_root.

Victor Stinner 211a392cc1 bpo-30320: test_eintr now uses pthread_sigmask() (#1523)
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).

Victor Stinner 5de85a1702 bpo-29972: Skip tests known to fail on AIX (#979)
* 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()

* bpo-28087: Skip test_asyncore and test_eintr poll failures on macOS

Skip some tests of select.poll when running on macOS due to unresolved
issues with the underlying system poll function on some macOS versions.

* test_eintr: support verbose mode, don't redirect eintr_tester output into

* eintr_tester: replace os.fork() with subprocess to have a cleaner child
  process (ex: don't inherit setitimer())
* eintr_tester: kill the process if the unit test fails
* test_open/test_os_open(): write support.PIPE_MAX_SIZE bytes instead of
  support.PIPE_MAX_SIZE*3 bytes

Victor Stinner f70e1ca0fc Issue #23485: select.select() is now retried automatically with the recomputed
timeout when interrupted by a signal, except if the signal handler raises an
exception. This change is part of the PEP 475.

The asyncore and selectors module doesn't catch the InterruptedError exception
anymore when calling select.select(), since this function should not raise
InterruptedError anymore.

2015-03-20 13:42:52 +01:00
Victor Stinner a453cd8d85 Issue #23715: signal.sigwaitinfo() and signal.sigtimedwait() are now retried
when interrupted by a signal not in the *sigset* parameter, if the signal
handler does not raise an exception. signal.sigtimedwait() recomputes the
timeout with a monotonic clock when it is retried.

Remove test_signal.test_sigwaitinfo_interrupted() because sigwaitinfo() doesn't
raise InterruptedError anymore if it is interrupted by a signal not in its
sigset parameter.

The _PyTime_ADD_SECONDS only supported an integer number of seconds, the
_PyTime_AddDouble() has subsecond resolution.
