CPAN::Testers::Common::Utils - Utility functions for CPAN Testers modules

version 0.002

     use CPAN::Testers::Common::Utils ':all';

     # NNTP ID <=> GUID mapping
     $guid    = nntp_to_guid( $nntp_id );
     $nntp_id = guid_to_nntp( $guid    );

This module contains common utility functions for use by other CPAN Testers modules

Legacy CPAN Testers reports were sent via email and made available via an NNTP group, C<perl.cpan.testers>. Reports were 'indexed' by their NNTP ID. The next generation of CPAN Testers uses a GUID URN to identify reports.

Old reports with an NNTP ID are mapped to GUIDs by replacing the first 8 hex characters of a common 'base GUID' with a zero-padded decimal representation of the NNTP ID.

   XXXXXXXX-b19f-3f77-b713-d32bba55d77f

Such GUID URNs are visually distinctive and have the nice feature of sorting earlier than second-generated report GUIDs based on a timestamp.

Two translation functions are provided for convenience.

     $guid    = nntp_to_guid( $nntp_id );

Given a numeric NNTP ID, returns a standard string-form GUID. (No range checking is done.) Examples:

   nntp_to_guid( 51432   );  # 00051432-b19f-3f77-b713-d32bba55d77f
   nntp_to_guid( 6171265 );  # 06171265-b19f-3f77-b713-d32bba55d77f

     $guid    = nntp_to_guid( $nntp_id );

Given a GUID string of the form described above, returns the decimal number in the first 8 characaters. Examples:

   guid_to_nntp( '00051432-b19f-3f77-b713-d32bba55d77f' ); # 51432
   guid_to_nntp( '06171265-b19f-3f77-b713-d32bba55d77f' ); # 6171265

If the GUID string is not derived from the base GUID, this function returns undef.
