OpenEMM Conversion Script
=========================
Please make sure that the OpenEMM application itself is stopped
and no other process accesses the database!
Temporary files are written to /tmp, so please make sure you have
enough space on your partition where /tmp is on.
If you would like to continue, press ENTER, to abort press Control-C.
__EOF__
echo -n '--> '
read dummy
if [ ! "$dummy" = "" ]; then
echo "Aborted."
exit 1

OpenEMM seems to be running, it will be now stopped.

Dumpfile $dbfile already exists, if you do not need it any more,
please remove the file and restart the script afterwards.
__EOF__
exit 1

#
cat << __EOF__
Now dumping the current content of the database to $dbfile
This may take some time, depending on the size of the database,
so be patient. You have to enter the root password of the
MySQL instance to start the dump:
__EOF__
mysqldump -aCceQ --lock-all-tables -u root -p -r $dbfile openemm
if [ $? -ne 0 ]; then
cat << __EOF__
Sorry, something went wrong, please consult the error message
and try to fix the problem, then restart the script.
__EOF__
rm -f $dbfile
exit 1
fi
#
cat << __EOF__
Now we convert the dumped to UTF-8, please stand by.
__EOF__
echo "ALTER DATABASE openemm DEFAULT CHARACTER SET utf8;" > $dbconv
sed -e 's/ \(character set utf8 \)\?collate utf8_unicode_ci//' \
-e 's/DEFAULT CHARSET=latin1/DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci/' \
< $dbfile >> $dbconv
if [ $? -ne 0 ]; then
cat << __EOF__
The conversion failed, please try to fix the problem and restart
the script.
__EOF__
rm -f $dbfile
exit 1
fi
#
cat << __EOF__
Conversion has finished, now we are going to drop the database and
reimport the modified data.
WARNING: Be sure to keep a backup just for the case! We DO NOT GIVE
ANY WARRANTY TO ANY DATA LOSS DUE TO THE CONVERSION! DO IT AT YOUR
OWN RISK!
Please type in YES if you really want to continue.
__EOF__
echo -n "Are you sure to continue? "

case "$ans" in

echo "Aborted, better luck next time."
rm -f $dbfile $dbconv
exit 0
;;
esac
#
cat << __EOF__
Now you are asked three times for the root password for the MySQL server,
first time drops the database, second time recreates it and third time
imports the saved data.
__EOF__
mode=0
while [ $mode -lt 3 ] ; do
case "$mode" in

echo "========== Drop database =========="
err="Drop of database failed"
mysqladmin -u root -p drop openemm

echo "========== Create database =========="
err="Recreation of database failed"
mysqladmin -u root -p create openemm
;;
2)
echo "========== Import into database =========="
err="Import of database failed"
mysql -u root -p openemm < $dbconv
;;
esac
if [ $? -ne 0 ]; then
cat << __EOF__
=====================================================
Error "$err" occurs.
=====================================================
If this is a simple error (like mistyped password) just press RETURN and
retry again. Otherwise, if you can fix the problem on the fly, fix it now
and press ENTER to continue. Otherwise (again) press Control-C or Break
to abort conversion. Be aware that your current database may now be lost,
so keep the original backup file $dbfile and the converted file $dbconv
to recover your database.
__EOF__
echo -n '--> '
read dummy

fi
done
#
cat << __EOF__
Congratulations, the conversion is completed sucessfully. Please log in and
verify that everything is working. WE KEEP THE ORIGINAL DUMP FILE IN $dbfile
SO YOU HAVE A BACKUP AT HAND. If everything is working, you can just remove
the file.
__EOF__
rm -f $dbconv

if [ $running -gt 0 ]; then
cat << __EOF__
Restart OpenEMM.
