Changes for version 0.59

  • ENHANCEMENTS:
  • Got rid of the post_select_hash hook and combined it with post_select, which now receives a hash reference. Suggested by Ilya Martynov.
  • Run all hooks inside Alzabo::Schema->run_in_transaction method to ensure database integrity in cases where your hooks might update/delete/insert data. Suggested by Ilya Martynov.
  • Added new Alzabo::Runtime::Table->select method. This is just like the existing ->function method, but returns a cursor instead of the entire result set.
  • Added a 'limit' parameter to the ->function method (also works for the ->select method).
  • Added new Alzabo::Runtime::Schema->select method. This is like the method of the same name in the table class but it allows for joins.
  • Added new potential rows, which are objects with (largely) the same interface as regular rows, but which are not (yet) inserted into the database. They are created via the new Alzabo::Runtime::Table->potential_row method. Thanks to Ilya Martynov for suggestions and code for this feature.
  • Added Alzabo::Runtime::Row->schema method. Suggested by Ilya Martynov.
  • Made it possible to use Storable to freeze and thaw any type of row object. Previously, this would have worked but would have serialized basically every single Alzabo object in memory (whee!). Patch by Ilya Martynov.
  • Make Alzabo::Schema->run_in_transaction preserve scalar/array context and return whatever was returned by the wrapped code.
  • BUG FIXES:
  • Did some review and cleanup of the exception handling code. There were some places where exceptions were being handled in an unsafe manner as well as some spots where exception objects should have been thrown that were just using die.
  • Ignore failure to rollback for MySQL when not using transactional table.
  • Alzabo was not handling the BETWEEN operator in where clauses properly. Patch by Eric Hillman.
  • Passing in something like this to rows_where:
    • ( where => [ $col_foo, '=', 1, $col_bar, '=', 2 ] )
  • Trying to do a select that involved a group by and a limit was not being allowed.
  • INCOMPATIBILITIES:
  • Got rid of the post_select_hash hook and combined it with post_select, which now receives a hash reference.
