dak.dakdb

Database update scripts for usage with dak update-db

@contact: Debian FTP Master <ftpmaster@debian.org> @copyright: 2008 Michael Casadevall <mcasadevall@debian.org> @license: GNU General Public License version 2 or later

Update scripts have to import psycopg2 and from daklib.dak_exceptions import DBUpdateError.

There has to be at least the function do_update(self) to be defined. It should take all neccessary steps to update the database. If the update fails the changes have to be rolled back and the DBUpdateError exception raised to properly halt the execution of any other update.

Example:

def do_update(self):
    print("Doing something")

    try:
        c = self.db.cursor()
        c.execute("SOME SQL STATEMENT")
        self.db.commit()

    except psycopg2.ProgrammingError as msg:
        self.db.rollback()
        raise DBUpdateError(f"Unable to do whatever, rollback issued. Error message: {msg}")

This function can do whatever it wants and use everything from dak and daklib.
