Comment 4 Elio Maldonado Batiz 2015-01-16 18:58:53 UTC

Based on the TCMS test test https://tcms.engineering.redhat.com/case/75306/
I have created a simplified version that doesn't require Beaker so I can
trace in the debugger.

Checkeout the test: rhpkg tests pyton nss
cd python-nss/Sanity/pkcs12-sanity-test/
and edited runtest.sh to run everything manually from this directory

PACKAGE=python-nss
TmpDir=`pwd`
cp *jdennis $TmpDir
for i in `rpm -ql python-nss-doc`; do
  echo $i | grep -e setup_certs.py$ -e test_pkcs12.py$ && cp $i $TmpDir
done
if [ !-e $TmpDir/setup_certs.py ]; then
  cp -p setup_certs.py.jdennis $TmpDir/setup_certs.py
fi
if [ !-e $TmpDir/test_pkcs12.py ]; then
  cp -p test_pkcs12.py.jdennis $TmpDir/test_pkcs12.py
fi
export NSS_DEFAULT_DB_TYPE=sql
echo "PKCS12 Sanity Test"
rm -rf pki
python setup_certs.py

# run the test_pkcs12.py one manually on gdb, backtrace will tell you
# the pk12util command to run in the debugger which will likely be 
# /usr/bin/pk12util -l exported_test_user.p12 -W pk12_passwd
# python test_pkcs12.py

I'm still debugging but let me make sure first, I'm doing the right thing.
Patrick, is this a faithful adaptation of your original test?

Comment 5 Elio Maldonado Batiz 2015-01-17 00:19:28 UTC

The if [ !-e...]; then lines above are in error. One totally remove those tests as we now the .py scripts are presenta nd ther is nothing to copy. I keep having problems with passwords whether on the debugger or not. One thing I did after the database was created is to export and list the exported file myself, as I had studied what pyton scrips do. I used these commands

pk12util -o exported_test_userManual.p12 -n test_user -d sql:./pki -K db_passwd -W "pk12_passwd"
pk12util -l exported_test_userManual.p12 -W "pk12_passwd"
and it listed just fine. 

I'm at a loss on how to explain the failures of the test. Patrick, perhaps we can meet on-line on IRC to analyse this and see what I may be doing wrong.

Comment 7 Elio Maldonado Batiz 2015-01-18 05:59:31 UTC

The cause I think is my incorrect fix for bug 1174527.

Bob rightly objected to me using strlen in his comment at
https://bugzilla.redhat.com/show_bug.cgi?id=1174527#c6 

Looking at the original attachment at
https://bugzilla.redhat.com/attachment.cgi?id=969405&action=diff
we see if (strlen(dest->data) >= 2 && ...
                                    ^^
I changed if (strlen(dest->data) >= 2 && ... to 
if ((dest->len < 2) && ..... )
               ^  reversing the sense of the test, bad

where I should have instead changed it to 
if ((dest->len >= 2) && ..... )
               ^^  preserving the sense of the original

This fixes the problem as far as my testing tells me. A scratch build with this change is at https://brewweb.devel.redhat.com/taskinfo?taskID=8556324.

Could someone please give it try?
