Attached below. I have to correct my statement: $PAGER isn't set for root. Sorry, I just checked only my environment. Since $PAGER isn't set, zypper tries to probe first "more". But, "more" isn't installed on my system. Then zypper removes the tmp file, still proceeds to "less" without the actual file. Do you still need zypper log, too? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The problem seems to be the wait() call. Look at the strace log above, in the middle: 6153 clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD , child_tidptr=0xb6f677b8) = 6199 6153 wait4(-1, NULL, 0, NULL) = 6195 6153 lstat64("/var/tmp/TmpFile.cltMcp", 6199 execve("/usr/sbin/sh", ["sh", "-c", "more /var/tmp/TmpFile.cltMcp"], [/* 2 0 vars */] 6153 <... lstat64 resumed> {st_mode=S_IFREG|0600, st_size=31126, ...}) = 0 6199 <... execve resumed> ) = -1 ENOENT (No such file or directory) 6153 unlink("/var/tmp/TmpFile.cltMcp" 6199 execve("/bin/sh", ["sh", "-c", "more /var/tmp/TmpFile.cltMcp"], [/* 20 var s */] 6153 <... unlink resumed> ) = 0 So, wait() returns immediately even though a child for "more" is still running. It could be because you already forked and wait() caught that child. A solution would be to use waitpid() instead of wait(). A patch is attached below. Unfortunately, I cannot test it now because of updates of boost package that broke everything. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I improved it a bit according to zypp's ExternalProgram class. I also found and fixed a problem with defined, but empty $PAGER. done in svn, to be in zypper 0.12.12. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
