How to run LIBC tests on VM environment

Note : If you already created dilos_BASE BE according the instruction, and there is no any new tested stable version, just execute the following command:

beadm activate dilos_BASE

In other case if you have already the dilos_ISO_orig BE - make the command:

beadm activate dilos_ISO_orig

Then reboot and start the instruction from the section Step 6. Prepare VM for Tests Running:

reboot

If you have no one of these 2 BEs then start the instruction from the beginning.

Note : Create ztest user if you forgot to do it according the instruction:

sudo useradd -m -d /var/ztest -g staff -s /bin/bash ztest

sudo passwd ztest

echo "ztest ALL=(ALL:ALL) NOPASSWD: ALL" >> /etc/sudoers.d/ztest

Note : If you already did it on the previous step when preparing VM to run, then you can skip this step and go to the next one.

Note : You can run the test using a shell script. It can be created with any text editor or by executing the following command:

ztest@zone:~# cat > test-script.sh <<EOT

#!/bin/bash

if [ -n "\$1" ]; then

CLOG="/var/tmp/libc-stability.\$(date +%F-%T).txt"

echo "=== Stability libc tests \$(date +%F-%T) ===" > \${CLOG}

for (( i=1; i<=\$1; i++ ))

do

echo "------------------ Pass \${i} ---------------------" 2>&1 | /usr/bin/tee -a \${CLOG}

LOG="/var/tmp/libc-test.\$i.txt"

uname -a > \${LOG}

/opt/libc-tests/bin/libctest 2>&1 | /usr/bin/tee -a \${LOG}

percent="\$(grep 'Percent passed:' \${LOG} | sed 's/Percent passed:[ \\t]*//; s/[ \\t]*\$//')"

folder="\$(grep 'Log directory:' \${LOG} | sed 's/Log directory:[ \\t]*//; s/[ \\t]*\$//')"

rt="\$(grep 'Running Time:' \${LOG} | sed 's/Running Time:[ \\t]*//; s/[ \\t]*\$//')"

echo " Percent passed: \${percent}" >> \${CLOG}

echo " Running Time: \${rt}" >> \${CLOG}

sed -n '/Results Summary/,/Log directory:/p' \${LOG} > a.tmp

echo "---------------------------------------------------------" >> a.tmp

echo "" >> a.tmp

cat \${LOG} >> a.tmp

mv -f a.tmp \${LOG}

if [ "\${percent}" == "100.0%" ]; then

sudo rm -r -f \${folder}

else

echo " PASS \${i} IS FAILED! (See \${LOG})" >> \${CLOG}

echo "Fault on \${i} pass! Just \${percent} are successfull. You can find logs in \${folder}." 2>&1 | /usr/bin/tee -a \${LOG}

exit 1

fi

done

else

LOG="/var/tmp/libc-test.\$(date +%F-%T).txt"

uname -a > \${LOG}

/opt/libc-tests/bin/libctest 2>&1 | /usr/bin/tee -a \${LOG}

fi

EOT

ztest@zone:~# sed -i '/./!d' test-script.sh && chmod 777 test-script.sh

You can run the test script in a single mode, i.e. all tests will be executed once (./test-script.sh - without parameters). After running of this script you will find the log in the /var/tmp/libc-test.<ISO TIME>.txt file. It will contain information in the format that is used in Test Results.

And the second one is stability mode - for testing the libc stability. In this case you should put the number of cycles (for example, to run 1000 cycles - ./test-script.sh 1000). And now after script is finished the common log will be placed to the /var/tmp/libc-stability.<ISO TIME>.txt file, and you will find logs about separate cycles in libc-test.<N>.txt form in the /var/tmp folder, where <N> - is a cycle number.
