Mark Dickinson c579b35740 Add extra information to a test_signal failure message to aid diagnosis of buildbot failure. 2009-11-09 19:54:51 +00:00
Mark Dickinson 4b841d9156 Issue #7042: Use a better mechanism for testing timers in test_signal. 2009-10-31 10:36:06 +00:00
Mark Dickinson 245d915e3e Issue #7042: Fix test_signal failure on OS X 10.6 64-bit builds
(and also, with luck, on the x86 FreeBSD buildbot), by making sure
that some user time is used in test_itimer_virtual.

Benjamin Peterson 888a39b54c remove test_support.TestSkipped and just use unittest.SkipTest 2009-03-26 20:48:25 +00:00
Jeffrey Yasskin ee76777846 Add enough debugging information to diagnose failures where the
HandlerBException is ignored, and fix one such problem, where it was thrown
during the __del__ method of the previous Popen object.

We may want to find a better way of printing verbose information so it's not
spammy when the test passes.

Jeffrey Yasskin e71d8124c2 Oops again. EINTR is in errno, not signal. 2008-04-04 16:48:19 +00:00
Jeffrey Yasskin 2b860db35c Doh! os.read() raises an OSError, not an IOError when it's interrupted.
And fix some flakiness in test_itimer_prof, which could detect that the timer
had reached 0 before the signal arrived announcing that fact.

Jeffrey Yasskin ab56131720 Try to make test_signal less flaky. I still see some flakiness in
test_itimer_prof.

Neal Norwitz bb89e686e3 Try to get this test to be more stable:
* disable gc during the test run because we are spawning objects and there
   was an exception when calling Popen.__del__
 * Always set an alarm handler so the process doesn't exit if the test fails
   (should probably add assertions on the value of hndl_called in more places)
 * Using a negative time causes Linux to treat it as zero, so disable that test.

Martin v. Löwis aef18b1c67 Patch #2240: Implement signal.setitimer and signal.getitimer. 2008-03-24 13:31:16 +00:00
Jeffrey Yasskin 413f588a36 Try to fix test_signal on FreeBSD. I'm assuming that os.kill is failing to
raise a signal, but switching to subprocess makes the code cleaner anyway.

Jeffrey Yasskin 6cda88ea11 Try to fix test_signal breakages on Linux due to r61687. It appears that at
least two of the linux build bots aren't leaving zombie processes around for
os.waitpid to wait for, causing ECHILD errors. This would be a symptom of a bug
somewhere, but probably not in signal itself.

Jeffrey Yasskin cf26f5419e Speed up test_signal from ~24s to 4s by avoiding nearly all of the sleep calls. 2008-03-21 05:02:44 +00:00
Christian Heimes acfd8ed0cd Windows fix for signal test - skip it earlier 2008-02-28 21:00:45 +00:00
Facundo Batista 7e251e83d5 Issue 1089358. Adds the siginterrupt() function, that is just a
wrapper around the system call with the same name.  Also added
test cases, doc changes and NEWS entry. Thanks Jason and Ralf
Schmitt.

Guido van Rossum 02de8979cc Patch #1583 by Adam Olsen.
This adds signal.set_wakeup_fd(fd) which sets a file descriptor to
which a zero byte will be written whenever a C exception handler runs.

I added a simple C API as well, PySignal_SetWakeupFd(fd).

Georg Brandl 9f2b93e03a Patch #1008: port test_signal to unittest. 2007-08-24 18:07:52 +00:00
Tim Peters 953c1897d2 Ah, fudge. One of the prints here actually "shouldn't be"
protected by "if verbose:", which caused the test to fail on
all non-Windows boxes.

Note that I deliberately didn't convert this to unittest yet,
because I expect it would be even harder to debug this on Tru64
after conversion.

Tim Peters 1742f3331f test_signal: Signal handling on the Tru64 buildbot
appears to be utterly insane.  Plug some theoretical
insecurities in the test script:

- Verify that the SIGALRM handler was actually installed.

- Don't call alarm() before the handler is installed.

- Move everything that can fail inside the try/finally,
  so the test cleans up after itself more often.

- Try sending all the expected signals in
  force_test_exit(), not just SIGALRM.  Since that was
  fixed to actually send SIGALRM (instead of invisibly
  dying with an AttributeError), we've seen that sending
  SIGALRM alone does not stop this from hanging.

- Move the "kill the child" business into the finally
  clause, so the child doesn't survive test failure
  to send SIGALRM to other tests later (there are also
  baffling SIGALRM-related failures in test_socket).

- Cancel the alarm in the finally clause -- if the
  test dies early, we again don't want SIGALRM showing
  up to confuse a later test.

Alas, this still relies on timing luck wrt the spawned
script that sends the test signals, but it's hard to see
how waiting for seconds can so often be so unlucky.

test_threadedsignals:  curiously, this test never fails
on Tru64, but doesn't normally signal SIGALRM.  Anyway,
fixed an obvious (but probably inconsequential) logic
error.
2006-08-12 04:42:47 +00:00
Tim Peters 8b8c59cf1d force_test_exit(): This has been completely ineffective
at stopping test_signal from hanging forever on the Tru64
buildbot.  That could be because there's no such thing as
signal.SIGALARM.  Changed to the idiotic (but standard)
signal.SIGALRM instead, and added some more debug output.

Neal Norwitz 313f8a903c Try to prevent hangs on Tru64/Alpha buildbot. I'm not certain this will help
and may need to be reverted if it causes problems.

Michael W. Hudson 43ed43bfc1 Take out my (long since disabled) POSIX signal mask handling code.
I'm not going to have the time or energy to get this working x-platform
-- anyone who does is welcome to the code!
2003-03-13 13:56:53 +00:00
Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Marc-André Lemburg 3661908a6a This patch removes all uses of "assert" in the regression test suite
and replaces them with a new API verify(). As a result the regression
suite will also perform its tests in optimization mode.

Fred Drake 004d5e6880 Make reindent.py happy (convert everything to 4-space indents!). 2000-10-23 17:22:08 +00:00
Thomas Wouters b9fa0a843e Raise 'TestSkipped' (from the test_support) module rather than 'ImportError'
to signify a test that should be marked as 'skipped' rather than 'failed'.
Also 'document' it, in README.

Barry Warsaw 5e056bbb76 test_rotor.py: New test of the rotor module.
test_*: converted to the new test harness.  GvR note!  test_signal.py
works interatively (i.e. when verbose=1) but does not work inside the
test harness.  It must be a timing issue, but I haven't figured it out
yet.
