From: Matthijs Kooijman Date: Thu, 1 Jan 2009 20:08:09 +0000 (+0100) Subject: mysql: Clean up vserver handling a bit. X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;h=4215d06b05dbfef0adf053f67c7839b6ae343810;p=matthijs%2Fupstream%2Fbackupninja.git mysql: Clean up vserver handling a bit. Use the same trick the ldap handler uses: Have two vars $vexec and $vdir, which are empty when running on the host and filled when running on a vserver. By prepending these vars at the right places, all of the explicit "if [ $use_vserver = yes ]" could be removed. --- diff --git a/handlers/mysql.in b/handlers/mysql.in index 7ff194e..f79a0b2 100644 --- a/handlers/mysql.in +++ b/handlers/mysql.in @@ -36,7 +36,6 @@ if [ $vservers_are_available = yes ]; then # everything ok info "Using vserver '$vsname'." usevserver=yes - vroot="$VROOTDIR/$vsname" else info "No vserver name specified, actions will be performed on the host." fi @@ -51,7 +50,15 @@ ignore='' for i in $ignores $nodata; do ignore="$ignore --ignore-table=$i" done - + +if [ $usevserver = yes ]; then + vroot="$VROOTDIR/$vsname" + vexec="$VSERVER $vsname exec" +else + vroot="" + vexec="" +fi + # create backup dirs, $vroot will be empty if no vsname was specified # and we will instead proceed to operate on the host [ -d $vroot$backupdir ] || mkdir -p $vroot$backupdir @@ -59,14 +66,8 @@ done hotdir="$backupdir/hotcopy" dumpdir="$backupdir/sqldump" -if [ $usevserver = yes ] -then - [ "$sqldump" == "no" -o -d $vroot$dumpdir ] || $VSERVER $vsname exec mkdir -p $dumpdir - [ "$hotcopy" == "no" -o -d $vroot$hotdir ] || $VSERVER $vsname exec mkdir -p $hotdir -else - [ "$sqldump" == "no" -o -d $dumpdir ] || mkdir -p $dumpdir - [ "$hotcopy" == "no" -o -d $hotdir ] || mkdir -p $hotdir -fi +[ "$sqldump" == "no" -o -d $vroot$dumpdir ] || $vexec mkdir -p $vroot$dumpdir +[ "$hotcopy" == "no" -o -d $vroot$hotdir ] || $vexec mkdir -p $vroot$hotdir ####################################################################### ## AUTHENTICATION @@ -89,13 +90,8 @@ defaultsfile="" if [ "$dbusername" != "" -a "$dbpassword" != "" ] then - if [ $usevserver = yes ] - then - vhome=`$VSERVER $vsname exec getent passwd "root" | @AWK@ -F: '{print $6}'` - home="$vroot$vhome" - else - home=`getent passwd "root" | @AWK@ -F: '{print $6}'` - fi + vhome=`$vexec getent passwd "root" | @AWK@ -F: '{print $6}'` + home=$vroot$vhome [ -d $home ] || fatal "Can't find root's home directory ($home)." @@ -129,12 +125,7 @@ user=$dbusername password="$dbpassword" EOF umask $oldmask - if [ $usevserver = yes ] - then - defaultsfile="--defaults-extra-file=$vhome/.my.cnf" - else - defaultsfile="--defaults-extra-file=$mycnf" - fi + defaultsfile="--defaults-extra-file=$vhome/.my.cnf" fi # if a user is not set, use $configfile, otherwise use $mycnf @@ -145,27 +136,17 @@ else userset=true; if [ $usevserver = yes ] then - vuserhome=`$VSERVER $vsname exec getent passwd "$user" | @AWK@ -F: '{print $6}'` + vuserhome=`$vexec getent passwd "$user" | @AWK@ -F: '{print $6}'` if [ $?
