Caught signal 2
[16:42:34]Test ../../../conformance/interfaces/sigaction/16-9.c FAILED: The

------------

Environment is as follows:
  - RHEL4.8 (kernel version 2.6.9-89)   --- (x86, x86_64, ia64)
  - RHEL5.5 (kernel version 2.6.18-194) --- (x86, x86_64, ia64)


The cause of above error is that sem_wait() of the testing kernel version
always returns with EINTR.

"man sem_wait" says:
------------
[...]

       EINTR  The call was interrupted by a signal handler.

[...]

NOTES
       A  signal handler always interrupts a blocked call to one of these
functions, regardless
       of the use of the sigaction(2) SA_RESTART flag.

POSIX.1-2001.
------------


And "man 7 signal" of "RHEL6.0 Beta"(*) says:
------------
       If a blocked call to one of the following interfaces is interrupted
by
       a  signal handler, then the call will be automatically restarted
after
       the signal handler returns if the SA_RESTART flag was used;
otherwise
       the call will fail with the error EINTR:

[...]

           * POSIX  semaphore  interfaces:  sem_wait(3)  and
sem_timedwait(3)
             (since Linux 2.6.22; beforehand, always failed with EINTR).

[...]

   Interruption of System Calls and Library Functions by Stop Signals
       On Linux, even in the absence of  signal  handlers,  certain
blocking
       interfaces  can fail with the error EINTR after the process is
stopped
       by one of the  stop  signals  and  then  resumed  via  SIGCONT.
This
       behavior is not sanctioned by POSIX.1, and doesn’t occur on other
sys-
       tems.

[...]

           * Linux 2.6.21 and earlier: futex(2) FUTEX_WAIT,
sem_timedwait(3),
             sem_wait(3).

------------
(*) -- Above description didn't exist in "man" of RHEL4.8/5.5.
       But "man" of RHEL6.0 Beta says that "sem_wait()" failed in the
       version earlier than Linux 2.6.22.


Therefore, These 26 tests are useful after 2.6.22 version, I think.

I tried to revised "testcases/open_posix_testsuite/conformance/interfaces/
sigaction/templates/template_16-1.in"

============

Above patch is revision only for templates.
The following procedure is necessary after applying patch:
------------
#cd testcases/open_posix_testsuite/conformance/interfaces/sigaction/
#./gentests.pl
------------

Similar revisions are necessary for other 25 "sigaction" tests.

    Sorry, but Linux-isms can't leak into the open_posix_testsuite.
Same with BSDisms (at least they shouldn't... if they do, then slap me
or whoever did the commit).
Thanks!

Do you mean the culprit is Linux-isms?
IMO, the test cases are good.

Mitani-san is proposing that I `fix' the testcases to work on RHEL
4.8. These testcases should function with minimal change for all
versions of Unix.

  This open_posix_suite is the part of LTP(linux test project), must we
make sure it can work at all versions of unix?

What about this patch?  If you think so, other similar patchs will be post.

-------------------------------------------------------------------------------

At older linux kernel(2.6.22 before), a signal handler always interrupts a
blocked call to one of these functions, regardless of the use of the sigaction
SA_RESTART flag, so we should not test these cases at this situation.

Althought uname is not exsit at 4.3 BSD, but this open_posix_suite just
the part of LTP(linux test project), so i think it's not a problem.

I use it in FreeBSD and others have used it in other versions of Unix
(in the past), based on the README. There's no reason why we need to
maintain something that philosophically diverges from the upstream
project's goal because it will make merging more painful and
unnecessary.

  OK, i get it. Thanks. ^_^

  Then, whether should we remove the following case, because it invokes
  the uname that it's not exsit at 4.3 BSD.

I applied Bian's patch in my system, and build succeeded.

I'm OK with the Bian's patch.

The uname() is part of the POSIX, for sure it's available on BSD.

Thinking of it, the patch that checks for kernel version only when
sysname == Linux should compile and work. But the question here is if we
want to bloat the tests with workarounds for broken systems. I would
rather see this covered by a database of known issues, so you can easily
copare results and read why your system is broken.

Well BSD 4.3 has been released in 1986. The recent BSD systems (tested
on FreeBSD 8.0) should be fine.
