After converting, the db.cfg file is # copied to a cache file usually at /var/lib/imap/rpm/db.cfg.cache to # allow bypassing this converting script if both files are identical. # While this is a bit less secure, it may be useful on big server where # db converting is done automatically. # # This script can safely be run as root, it will reexec itself as user # cyrus if needed. # # author: Simon Matter, Invoca Systems <simon.matter@invoca.ch> # changelog # v1.0.1, Oct 22 2002 Simon Matter <simon.matter@invoca.ch> # - added two-step conversion method # # v1.0.2, Jan 10 2003 Simon Matter <simon.matter@invoca.ch> # - fixed a bug where cvt_cyrusdb was called to convert empty or # nonexistent files # # v1.0.3, Mar 14 2003 Simon Matter <simon.matter@invoca.ch> # - fixed a problem with new versions of the file command # # v1.0.4 # - added GPL license # # v1.0.5, May 02 2003 Simon Matter <simon.matter@invoca.ch> # - modified exec path # # Extra modifications for Mandrake RPM by # Luca Olivetti <luca@olivetti.cjb.net>: # # - get spool directory from config file # - get system_magic from file --version # - Dec 01 2003 added annotations.db for cyrus-2.2.2 # - Dec 01 2003 changed "db3" to "berkeley" # - Jan 15 2003 get db configuration from /etc/imapd.conf if [ -n "`/sbin/pidof cyrus-master`" ]; then echo "ERROR: cyrus-master is running, unable to convert mailboxes!" exit 1 fi if [ ! -f /etc/imapd.conf ]; then echo "ERROR: configuration file not found." exit 1 fi # force cyrus user for security reasons if [ ! $(whoami) = "cyrus" ]; then exec su - cyrus -c "cd $PWD ; $0" fi # take system magic location from file --version system_magic=`file --version | awk '/magic file/ {print $4}'` cyrus_magic=/usr/share/cyrus-imapd/rpm/magic cvt_cyrusdb=/usr/lib/cyrus-imapd/cvt_cyrusdb # get_config [config default] # extracts config option from config file get_config() { if config=`grep "^$1" /etc/imapd.conf` ; then echo $config | cut -d: -f2 | sed -e 's/^ *//' -e 's/-nosync//' -e 's/ *$//' else echo $2 fi } # get imap directory from config file imap_prefix=`get_config configdirectory /var/lib/imap` # files get mode 0600 umask 166 # get database backends from config file CONFIG_DB_DUPLICATE=`get_config duplicate_db berkeley` CONFIG_DB_MBOX=`get_config mboxlist_db skiplist` CONFIG_DB_SEEN=`get_config seenstate_db skiplist` CONFIG_DB_SUBS=`get_config subscription_db flat` CONFIG_DB_TLS=`get_config tlscache_db berkeley` CONFIG_DB_ANNOTATION=`get_config annotation_db skiplist` # file_type [file] file_type() { this_type=$(file -b -m "$system_magic:$cyrus_magic" "$1") if echo "$this_type" | grep -qi skip > /dev/null 2>&1; then echo skiplist elif echo "$this_type" | grep -qi text > /dev/null 2>&1; then echo flat else echo berkeley fi } # cvt_file [file] [db] cvt_file() { target="$1" new_db="$2" if [ -s "$target" ]; then old_db=$(file_type "$target") if [ !
