NAME ^

CPAN::SQLite::META - helper module for CPAN.pm integration

DESCRIPTION ^

This module has no direct public interface, but is intended as a helper module for use of CPAN::SQLite within the CPAN.pm module. A new object is created as

  my $obj = CPAN::SQLite::META->new($CPAN::META);

where $CPAN::META comes from CPAN.pm. There are then two main methods available.

set

This is used as

   $obj->set($class, $id);

where $class is one of CPAN::Author, CPAN::Module, or CPAN::Distribution, and $id is the id CPAN.pm uses to identify the class. The method searches the CPAN::SQLite database by name using the appropriate author, dist, or module mode, and if a result is found, calls

    $CPAN::META->instance(
                         $class => $id
                         )->set(
                          %attributes
                         );

to register an instance of this class within CPAN.pm.

ssearch

This is used as

   $obj->search($class, $id);

where $class is one of CPAN::Author, CPAN::Module, or CPAN::Distribution, and $id is the id CPAN.pm uses to identify the class. The method searches the CPAN::SQLite database by query using the appropriate author, dist, or module mode, and if results are found, calls

    $CPAN::META->instance(
                         $class => $id
                         )->set(
                          %attributes
                         );

for each match to register an instance of this class within CPAN.pm.

The attributes set within $CPAN::META-instance> depend on the particular class.

author

The attributes are

       'FULLNAME' => $results->{fullname},
       'EMAIL' => $results->{email},

where $results are the results returned from CPAN::SQLite.

module

The attributes are

        'description' => $results->{mod_abs},
        'userid' => $results->{cpanid},
        'CPAN_VERSION' => $results->{mod_vers},
        'CPAN_FILE' => $results->{download},
        'CPAN_USERID' => $results->{cpanid},
        'chapterid' => $results->{chapterid},
        %dslip,

where $results are the results returned from CPAN::SQLite. Here, %dslip is a hash containing keys statd, stats, statl, stati, and statp, with corresponding values being the registered dslip entries for the module, if present.

dist

The attributes are

       'DESCRIPTION' => $results->{dist_abs},
       'CPAN_USERID' => $results->{cpanid},
       'CPAN_VERSION' => $results->{dist_vers},

As well, a CONTAINSMODS key to $CPAN::META is added, this being a hash reference whose keys are the modules contained within the distribution.

There is also a method available reload, which rebuilds the database. It can be used as

   $obj->reload(force => 1, time => $time);

The time option (which, if not passed in, will default to the current time) will be used to compare the current time to the mtime of the database file; if they differ by more than one day, the database will be rebuilt. The <force> option, if given, will force a rebuilding of the database regardless of the time difference.
