Continuous Integration on Python

Hudson and Cruise Control are very popular among Java/.Net developers but when it comes to Python, …
Hudson also seems to work on python!. Open source tools for Python continuous integration:

However, I just want a simple way to check out the code and run the tests. A Bash script and the Cron daemon is a good solution so far (last script update on Wed 25 Feb 2008):

cd /root/siga/src
export DJANGO_SETTINGS_MODULE="settings" 
export PYTHONPATH=":/root/siga/src"

mailTo="developer1@sample.com, developer2@whatever.com"

analize_tests_output () 
{
   grep "FAIL:" $1 > failResults
   if [[ $? == 0 ]]
   then
      echo "There are tests failing!:" > tmp
      cat failResults >> tmp
      mail -s "Continuous integration report" $mailTo < tmp
   fi
   grep "ERROR:" $1 > errorResults
   if [[ $? == 0 ]]
   then
      echo "There are tests with errors!:" > tmp
      cat failResults >> tmp
      mail -s "Continuous integration report" $mailTo < tmp
      return
   fi

   rm -rf $1
}

are_there_changes()
{
        svn up > tmpsvnup

        grep "^U" tmpsvnup  2>  /dev/null > /dev/null
        if [[ $? == 0 ]]
        then
           return 1
        fi

        grep "^A" tmpsvnup  2>  /dev/null > /dev/null 
        if [[ $? == 0 ]]
        then
           return 1
        fi

        grep "^D" tmpsvnup  2>  /dev/null > /dev/null
        if [[ $? == 0 ]]
        then
           return 1
        fi

        grep "^G" tmpsvnup  2> /dev/null > /dev/null
        if [[ $? == 0 ]]
        then
           return 1
        fi

        return 0
}

are_there_changes
changes=$?
if [[ $changes == 1 ]] # there are svn changes
then
   /etc/init.d/wservices stop
   sleep 2
   /etc/init.d/wservices start
