200162 - semaerr and semaping fail on some HP-UX 11.00 machines

Status: RESOLVED FIXED

(NSPR :: NSPR, defect)

Description

[Wan-Teh Chang]

The 32-bit HP-UX PA-RISC builds (both debug and optimized)
of semaerr and semaping fail on some HP-UX 11.00 machines,
for example, sorrento and salerno at Netscape and charm at
Sun.  This problem is in NSPR as early as 4.1.2.

In NSPR 4.3, the test output looks like this:

BEGIN TEST: semaerr  
Thu Mar 27 11:53:31 PST 2003 OBJDIR HP-UXB.11.00_DBG.OBJ LIBS
/share/builds/mccrel3/nspr/nspr43/builds/20030327.1/smarch_HPUX11.00/hpux32_dbg/dist/lib
Expected error is -5950 but got (-5987, 22)
semaerr returned 1 (failed) 
END TEST: semaerr 
BEGIN TEST: semaping  
Thu Mar 27 11:53:31 PST 2003 OBJDIR HP-UXB.11.00_DBG.OBJ LIBS
/share/builds/mccrel3/nspr/nspr43/builds/20030327.1/smarch_HPUX11.00/hpux32_dbg/dist/lib
PR_OpenSemaphore failed (-5987, 22)
Killing semaping 8962 after 600 
kill: 8963: The specified process does not exist.
semaping returned 143 (failed) 
END TEST: semaping

Attachment: Proposed patch

HP tracked down the cause of these test failures.
It is a bug in sem_open: sem_open still reads the
third and fourth arguments when the O_CREAT flag
is not specified.  We can work around this by
passing 0 as the third and fourth arguments to
sem_open in that case.

Fix checked into the NSPR tip (NSPR 4.5) and the
NSPRPUB_PRE_4_2_CLIENT_BRANCH (Mozilla 1.7 beta).
