grml-live-db(8) =============== Name ---- grml-live-db - log package build information of grml-live to database Synopsis -------- dpkg-to-db [ options ] || db-to-fai /path/to/grml-live.db Introduction ------------ The grml-live-db Debian package provides a simple way to put build information of grml-live into a database. By default you have to do nothing but install grml-live-db and during each invocation of grml-live you'll get an additional entry in the sqlite3 database /var/log/grml-live.db. If you want to customize the database logging check out the following sections in this manpage. Provided scripts ---------------- /usr/share/grml-live-db/scripts/dpkg-to-db adds grml-live build information (output of 'dpkg --list') and a logfile into a sqlite3 database. This script is used by default if grml-live-db is installed (no configuration needed by default). /usr/share/grml-live-db/scripts/db-to-fai converts output of grml-live's sqlite database for use within FAI. This script is useful if you want to reproduce a certain build with specific package versions. Please note that you need the according Debian mirrors providing all the specific package versions of course. Options ------- dpkg-to-db supports the following options (and all except for --help are mandatory!): --help Print help message and exit. --database Use specified database file. --dpkg Use specified dpkgfile as `dpkg --list` output file of grml-live build. --logfile Logfile thath should be added to the database entry. --flavour Name of the grml-live flavour that was being built. The db-to-fai script does not support any options but needs to be invoked with path to the grml-live database and the build id. Configuration and using custom database wrapper scripts ------------------------------------------------------- The following configuration variables are available and can be adjusted: DPKG_DATABASE=/var/log/grml-live.db Path to the database file that should be used for storing the build information. This database is used within dpkg-to-db by default. DPKG_DBSCRIPT=/usr/share/grml-live-db/scripts/dpkg-to-db The database wrapper script that's used for storing the build information. If you do not want to log to the sqlite3 database but instead use your own abstraction layer just point this variable to your favourite script. DPKG_DBOPTIONS="--database $DPKG_DATABASE --logfile $LOGFILE --flavour $GRML_NAME --dpkg $DPKG_LIST" If the database script ($DPKG_DBSCRIPT) requires any command line options specify it through this variable. Usage Examples -------------- How dpkg-to-db is being used inside grml-live: /usr/share/grml-live-db/scripts/dpkg-to-db --database /var/log/grml-live.db --logfile /var/log/grml-live.log --flavour $GRML_NAME --dpkg /var/log/fai/$HOSTNAME/last/dpkg.list Manually insert data to database: # /usr/share/grml-live-db/scripts/dpkg-to-db --database ./grml-live.db --logfile /tmp/logfile --flavour grml-full --dpkg ./dpkg.list Retrieve build information of a specific build for use within FAI: # /usr/share/grml-live-db/scripts/db-to-fai /var/log/grml-live.db 6 > /etc/grml/fai/config/package_config/REPRODUCE Describe schema of database: # echo '.schema' | sqlite3 /var/log/grml-live.db Database queries: # echo 'SELECT package,version,status,build.flavour,build.identifier FROM packages, build WHERE build.identifier = "grml-full-20091213012517" AND packages.build = build.id ; ' | sqlite3 /var/log/grml-live.db # echo 'SELECT package,version,status,build.flavour,build.identifier FROM packages, build WHERE build.id = 7 AND packages.build = build.id ; ' | sqlite3 /var/log/grml-live.db
