307582 - nameshm1 test case hangs on AIX and can hang on Solaris

Status: RESOLVED INACTIVE

(NSPR :: NSPR, defect)

Description

[Jason Reid]

nameshm1 hangs on AIX 5.1 and Solaris 5.8. Since it
works on Solaris 10 machines, I suspect this is
an OS issue. Documenting this in case someone searches.

This also occurs on Solaris 9.

And on Mac OS X:

$ DYLD_LIBRARY_PATH=../../dist/lib ./nameshm1                        
Assertion failure: sem1, at ../../../mozilla/nsprpub/pr/tests/nameshm1.c:442
Abort trap
$

This is from a freshly built NSPR version 4.6.8.

Comment 3

[Wan-Teh Chang]

An assertion failure is different from a hung test.  So the assertion failure
on Mac OS X is a different problem.  The assertion at line 442 fails because
NSPR interprocess semaphores are not implemented on Mac OS X:

441     sem1 = PR_OpenSemaphore( SEM_NAME1, PR_SEM_CREATE, SEM_MODE, 0 );
442     PR_ASSERT( sem1 );

So PR_OpenSemaphore always fails with error -5992 (PR_NOT_IMPLEMENTED_ERROR).

(note: identical comment in bug 408799)

Is there a bug in the system somewhere saying something like 'no implementation of semaphores for Mac'? I searchd for 'semaphore' in any comment and did not find one.

It is possible to do some kind of semaphore on a Mac. So, what is the actual issue? Bug 408799 says there is something missing on the Mac. If so, do you have a radar bug # for a bug with Apple? If there is such a bug, I might be able to track it down with people in Apple.

The bug assignee is inactive on Bugzilla, so the assignee is being reset.
