Neal Norwitz 84bc19a453 Restore rev 47014:
The hppa ubuntu box sometimes hangs forever in these tests.  My guess
is that the wait is failing for some reason.  Use WNOHANG, so we won't
wait until the buildbot kills the test suite.

I haven't been able to reproduce the failure, so I'm not sure if
this will help or not.  Hopefully, this change will cause the test
to fail, rather than hang.  That will be better since we will get
the rest of the test results.  It may also help us debug the real problem.

*** The reason this originally failed was because there were many
zombie children outstanding before rev 47158 cleaned them up.
There are still hangs in test_subprocess that need to be addressed,
but that will take more work.  This should close some holes.

Neal Norwitz b15ac3169d Add new utility function, reap_children(), to test_support. This should
be called at the end of each test that spawns children (perhaps it
should be called from regrtest instead?).  This will hopefully prevent
some of the unexplained failures in the buildbots (hppa and alpha)
during tests that spawn children.  The problems were not reproducible.
There were many zombies that remained at the end of several tests.
In the worst case, this shouldn't cause any more problems,
though it may not help either.  Time will tell.

Neal Norwitz 05a45599d7 Patch #1309579: wait3 and wait4 were added to the posix module by Chad J. Schroeder.
This was a fair amount of rework of the patch.  Refactored test_fork1 so it
could be reused by the new tests for wait3/4.  Also made them into new style
unittests (derive from unittest.TestCase).

Moshe Zadka fc3fc337d0 Checking in patch #103478 -- makes popen2 and fork1 tested on BeOS.
Tested for not breaking builds on Linux.

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 56221a7cfa Chris Herborth <chrish@pobox.com>:
Minor updates for BeOS R5.

Use of OSError in test.test_fork1 changed to TestSkipped, with corresponding
change in BeOS/README (by Fred).

This closes SourceForge patch #100978.

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.

Guido van Rossum c1488413e4 Added a provision to stop all threads before exiting from the test:
the change to regrtest.py to unload all newly imported modules did
something bad to the threads -- and I realized that they would never
stop!

Fred Drake 1a4b593dd6 Use a constant to specify the number of child threads to create.
Instead of assuming that the number process ids of the threads is the
same as the process id of the controlling process, use a copy of the
dictionary and check for changes in the process ids of the threads
from the thread's process ids in the parent process.  This makes the
test make more sense on systems which assign a new pid to each thread
(i.e., Linux).

This doesn't fix the other problems evident with this test on Linux.

Guido van Rossum f7221c3a7d Test case for fork1() behavior.
Only the main thread should survive in the child after a fork().
