I have an issue with import and inheritance that I cannot figure out. When a certain module of mine is loaded at runtime, it forces a chain of requires through the DBIx::SQLEngine distribution, leading to this error:
Advertising
"new_group_from_values" is not exported by the DBIx::SQLEngine::Criteria module Can't continue after import errors at /home/terry/perl/share/perl/5.8.7/DBIx/SQLEngine/RecordSet/Set.pm line 318 BEGIN failed--compilation aborted at /home/terry/perl/share/perl/5.8.7/DBIx/SQLEngine/RecordSet/Set.pm line 318.

[Fri Sep 9 01:25:56 2005] [error] [client 24.130.176.67] Premature end of script headers: /var/www/terry/metaperl.org/cgi-bin/Guestbook.cgi ... and if you look at the file Criteria.pm you would not be surprised to see this import error because no such sub exists in this file: http://hcoop.net/~terry/perl/share/perl/5.8.7/DBIx/SQLEngine/Criteria.pm However, I can run 2 separate static small scripts which emulate what is happening during the above chain of failed requires and they all work. First, a script which loads Guestbook::Model::entry (the module whose require from Guestbook::App::sign_commit creates the error chain) and does a commit to database... it does the commit perfectly. entry.pl and entry.pm are here: http://www.metaperl.org/Guestbook/Model/ In other words, even though it loads Guestbook::Model::entry, it does not fail when loading the other modules in the DBIx::SQLEngine distribution. Now, the last thing that happens before the "not exported" error is that Record/Table.pm does a require DBIx::SQLEngine::RecordSet::Set, so I wrote a script which only does that and it runs just fine: http://hcoop.net/~terry/perl/share/perl/5.8.7/DBIx/SQLEngine/RecordSet/Set.pl So, the question becomes: why is it when CGI::Prototype::PathInfo does a dynamic require of Guestbook::App::sign_commit and then Guestbook::App::sign_commit does a use Guestbook::Model::entry that the above chain of errors is thrown? You can view PathInfo.pm here: http://hcoop.net/~terry/perl/lib/CGI/Prototype/PathInfo.pm -- Carter's Compass: I know I'm on the right track when, by deleting something, I'm adding functionality. ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ cgi-prototype-users mailing list cgi-prototype-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/cgi-prototype-users
