CPAN::SQLite::Index(3) User Contributed Perl Documentation CPAN::SQLite::Index(3)

CPAN::SQLite::Index - set up or update database tables.

 my $index = CPAN::SQLite::Index->new(setup => 1);
 $index->index();

This is the main module used to set up or update the database tables used to store information from the CPAN and ppm indices. The creation of the object

 my $index = CPAN::SQLite::Index->new(%args);

accepts two possible arguments:

  • setup => 1

    This (optional) argument specifies that the database is being set up. Any existing tables will be dropped.

  • reindex => value

    This (optional) argument specifies distribution names that one would like to reindex in an existing database. These may be specified as either a scalar, for a single distribution, or as an array reference for a list of distributions.

Calling

  $index->index();

will start the indexing procedure. Various messages detailing the progress will written to STDOUT, which by default will be captured into a file cpan_sqlite_log.dddddddddd, where the extension is the "time" that the method was invoked. Error messages are not captured, and will appear in STDERR.

The steps of the indexing procedure are as follows.

  • fetch index data

    The necessary CPAN index files $CPAN/authors/01mailrc.txt.gz, $CPAN/modules/02packages.details.txt.gz, and $CPAN/modules/03modlist.data.gz will be fetched from the CPAN mirror specified by the $cpan variable at the beginning of CPAN::SQLite::Index. If you are using this option, it is recommended to use the same CPAN mirror with subsequent updates, to ensure consistency of the database. As well, the information on the locations of the CPAN mirrors used for Template-Toolkit and GeoIP is written.

  • get index information

    Information from the CPAN indices is extracted through CPAN::SQLite::Info.

  • get state information

    Unless the "setup" argument within the "new" method of CPAN::SQLite::Index is specified, this will get information on the state of the database through CPAN::SQLite::State. A comparision is then made between this information and that gathered from the CPAN indices, and if there's a discrepency in some items, those items are marked for either insertion, updating, or deletion, as appropriate.

  • populate the database

    At this stage the gathered information is used to populate the database, through CPAN::SQLite::Populate, either inserting new items, updating existing ones, or deleting obsolete items.

CPAN::SQLite::Info, CPAN::SQLite::State, CPAN::SQLite::Populate, and CPAN::SQLite::Util. Development takes place on the CPAN-SQLite project at <http://sourceforge.net/projects/cpan-search/>.
