Results for s390 (was Re: LSB 3.1 status for etch)

And I have been contacted; thanks to all of you.

One person, Frans Pop, has kindly pointed me to hercules, the s390
emulator, and has run the tests under it.  These results can tell us a
lot about the platform, but can also be misleading in other areas; to
what extent is the test finding bugs in the runtime vs. finding bugs in
the emulator?  So, they should be looked at in that light.

I here post the results that are different from the i386 results I
posted earlier.

First of all, there are no results yet for vsw4 (the X11 test) or
desktop.  This is due to the xvfb package being missing from etch for
s390.  Strictly speaking, the LSB does not require that runtimes provide
xvfb, but it does make running the tests easier.  I have not yet looked
into finding an appropriate xvfb (perhaps the sarge package, if one
exists; the xvfb from the LSB sample implementation might also work).

Here are the results we do have:

>From "lsb-runtime-test":

/tset/ANSI.os/genuts/abort/T.abort 11 UNREPORTED
/tset/ANSI.os/genuts/exit/T.exit 5 UNREPORTED
/tset/LSB.os/ipc/shmctl/T.shmctl 15 UNREPORTED

Frans did report that there were occasions where the test appeared to
hang; in at least one of these cases, the test had been running for 20
hours, which is excessive.  All of these results are marked in the
journal as coming from a SIGTERM applied to the test.

/tset/ANSI.os/maths/exp/T.exp 1 FAIL
/tset/ANSI.os/maths/pow/T.pow 1 FAIL

These appear to be floating point precision errors.  Here, for example,
are the journal results for the T.pow test:

I don't know to what extent these are bugs in the emulator.

>From "libchk":

libGL.so.1 1 FAIL

This was caused by a missing OpenGL library.

>From the C++ tests:

/24_iterators/istreambuf_iterator/2.cc 1 FAIL
/demangle/abi_examples/01.cc 1 FAIL
/demangle/abi_examples/02.cc 1 FAIL

This is actually a correction to the C++ tests on i386.  I neglected to
report these results due to an oversight.  All of these are problems in
the test suite and are already waived.

/22_locale/locale/cons/12658_thread.cc 1 FAIL
/thread/pthread4.cc 1 FAIL

The thread tests are always sensitive to running under an emulator, so
I'm hesitant to say for sure whether these are real failures.
