Hi,
I am trying to run memcg control testcase using script memcg_control_test.sh.
This script calls a memory hog process 'mem_process'.
The condition for this testcase to pass is 'when the memory hog process is
killed on crossing boundary'. please check the below function.
<taken from memcg_control_test.sh>
-----------------------------
# Check if the test process is killed on crossing boundary
test_proc_kill()
{
( cd $TMP && mem_process -m $PROC_MEM & )
sleep 1
echo $! > tasks
#Instruct the test process to start acquiring memory
echo m > $STATUS_PIPE
sleep 5
#Check if killed
ps -p $! > /dev/null 2> /dev/null ----> at this point the process
'mem_process' must have terminated so that last return value ($?) can be
non-zero.
if [ $? -eq 0 ]; then
echo m > $STATUS_PIPE
echo x > $STATUS_PIPE
else
: $((KILLED_CNT += 1))
fi
}
-------------------------
In my case: 'mem_process' does not terminate until we pass 'x' to it, but the
expected behaviour according to testcase that the memory hog process
must be killed on crossing bounday.
Inputs taken by testcase are : "./memcg_control_test.sh 4096 4096 8192"
If I change the inputs from 8192 to other (1024,10MB,100MB etc) . In all
situation memory hog process does not terminate.
So what is the ideal condition for this process to terminate to make whole
testcase pass. ?
