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.
Add a new function uses_seh() to the _ctypes extension module. This
will return True if Windows Structured Exception handling (SEH) is
used when calling functions, False otherwise.
str() or repr()) would work, just not multi-value tuples. Probably not a
backport candidate, since it changes the behaviour of passing a
single-element tuple:
>>> string.Template("$foo").substitute(dict(foo=(1,)))
'(1,)'
versus
'1'
will return True if Windows Structured Exception handling (SEH) is
used when calling functions, False otherwise.
Currently, only MSVC supports SEH.
Fix the test so that it doesn't crash when run with MingW compiled
_ctypes. Note that two tests are still failing when mingw is used, I
suspect structure layout differences and function calling conventions
between MSVC and MingW.
handler would cause a segfault. This merges in Expat's lib/xmlparse.c
revisions 1.154 and 1.155, which fix this and a closely related problem
(the later does not affect Python).
Moved the crasher test to the tests for xml.parsers.expat.
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.
(modified patch by Sam Ruby; changed to use separate REs for start and end
tags to reduce matching cost for end tags; extended tests; updated to avoid
breaking previous changes to support IPv6 addresses in unquoted attribute
values)
consistent with os.wait() returning immediately because some other
subprocess had previously exited; the test suite then immediately
tries to lock the mailbox and gets an error saying it's already
locked.
To fix this, do a waitpid() so the test suite only continues once
the intended child process has exited.
