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.
* 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.
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.
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).
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.
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.
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.
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. :)
[ 559250 ] more POSIX signal stuff
Adds support (and docs and tests and autoconfery) for posix signal
mask handling -- sigpending, sigprocmask and sigsuspend.
and replaces them with a new API verify(). As a result the regression
suite will also perform its tests in optimization mode.

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.
