[LTP] Failure for test fork09 in the ltp when called through shell script using eval command.

[pravin <pr...@li...>]

Hi Carmelo,

I have observed a failure for test fork09 in the ltp when called through 
shell script using eval command.
I am using LTP version ltp-full-20071231.

Subrata has told me that,
your patch dated "Thu Oct 4 16:46:50 2007 UTC" is the last change on 
fork09 test.
There seems to be change in the way we define OPEN_MAX variable, and I 
doubt, if this is causing the failure.


Please see below sample fork09_failure.sh to reproduce the problem
fork09_failure.sh:-
============
#!/bin/sh

echo "Begin test script"

echo "abort01 ulimit -c 1024;abort01" > /opt/fiv/ltp/runtest/my-tests
echo "fork01 fork01" >> /opt/fiv/ltp/runtest/my-tests
echo "fork02 fork02" >> /opt/fiv/ltp/runtest/my-tests
echo "fork03 fork03" >> /opt/fiv/ltp/runtest/my-tests
echo "fork04 fork04" >> /opt/fiv/ltp/runtest/my-tests
echo "fork05 fork05" >> /opt/fiv/ltp/runtest/my-tests
echo "fork06 fork06" >> /opt/fiv/ltp/runtest/my-tests
echo "fork07 fork07" >> /opt/fiv/ltp/runtest/my-tests
echo "fork08 fork08" >> /opt/fiv/ltp/runtest/my-tests
echo "fork09 fork09" >> /opt/fiv/ltp/runtest/my-tests
echo "fork10 fork10" >> /opt/fiv/ltp/runtest/my-tests
echo "fork11 fork11" >> /opt/fiv/ltp/runtest/my-tests

exec 5<> /tmp/thisisdummyfile

cmdstr="/opt/fiv/ltp/runltp -d /tmp -p -f my-tests -l mytest.log -o 
/tmp/mytest.out"
(eval $cmdstr 5>&-; echo "Extra Message")     #fork09 test fail
(eval $cmdstr ; echo "Extra Message")         #fork09 test pass

echo "End of script"



Error Message is,

<<<test_start>>>

Could you confirm whether it's fork09 testcase issue.

Please let me know if you need any more information.


Thank you,
