CPAN::SQLite::State - get state information on the database


version 0.219


This module gets information on the current state of the database and compares it to that obtained from the CPAN index files from CPAN::SQLite::Info and from the repositories from CPAN::SQLite::PPM. For each of the four tables dists, mods, auths, and ppms, two methods are used to get this information:

  • ids

    This method gets the ids of the relevant names, and versions, if applicable, in the table.

  • state

    This method compares the information in the tables obtained from the ids method to that from the CPAN indices and ppm repositories. One of three actions is then decided, which is subsequently acted upon in CPAN::SQLite::Populate.

    • insert

      If the information in the indices is not in the database, this information is marked for insertion.

    • update

      If the information in the database is older than that form the indices (generally, this means an older version), the information is marked for updating.

    • delete

      If the information in the database is no longer present in the indices, the information is marked for deletion.
