Detailed Description

A python rpmdb object represents an RPM database.

Instances of the rpmdb object provide access to the records of a RPM database. The records are accessed by index number. To retrieve the header data in the RPM database, the rpmdb object is subscripted as you would access members of a list.

The rpmdb class contains the following methods:

Note that in most cases, one is interested in querying the default database in /var/lib/rpm and an rpm.mi match iterator derived from an implicit open of the database from an rpm.ts transaction set object:

        import rpm
        ts = rpm.TransactionSet()
        mi = ts.dbMatch()
        ...
is simpler than explicitly opening a database object:
        import rpm
        db = rpm.opendb()
        mi = db.match()

An example of opening a database and retrieving the first header in the database, then printing the name of the package that the header represents:

        import rpm
        db = rpm.opendb()
        mi = db.match()
        if mi:
            h = mi.next()
            if h:
                print h['name']

To print all of the packages in the database that match a package name, the code will look like this:

        import rpm
        db = rpm.opendb()
        mi = db.match('name', "foo")
        while mi:
            h = mi.next()
            if not h:
                break
            print "%s-%s-%s" % (h['name'], h['version'], h['release'])
