Changes for version 0.58

  • ENHANCEMENTS:
  • Added new insert_hooks, update_hooks, select_hooks, and delete_hooks options to Alzabo::MethodMaker. Suggested by Ilya Martynov.
  • Moved all the important document for the object caching system into Alzabo::ObjectCache, including the import options for all of the various modules.
  • Added Alzabo::ObjectCache::Sync::RDBMS & Alzabo::ObjectCache::Store::RDBMS. The former finally allows synchronization of multiple processes across multiple machines!
  • Add Alzabo::Schema->has_table and Alzabo::Table->has_column methods.
  • Make BYTEA a legal column type for postgres. This is treated as a blob type.
  • BUG FIXES:
  • The way cardinality and dependency was being represented in the schema graphs was sometimes backward and sometimes just broken.
  • Fixed Alzabo::ObjectCache::Store::BerkeleyDB->clear, which was not actually doing anything. Added tests that catch this.
  • The lookup_tables option, which was deprecated in 0.57, was not being allowed at all.
  • Calls to select_hash on cached rows were not going through the cache checking routines, possibly returning expired data. Added tests for this.
  • Eliminate race condition in Alzabo::ObjectCache::Sync::BerkeleyDB.
  • The Alzabo::Runtime::Row->rows_by_foreign_key method wasn't doing quite what it said. In cases where there was a 1..1 or n..1 relationship to columns that were not the table's primary key, a cursor would be returned instead of a single row. Reported by Ilya Martynov.
  • Alzabo::MethoMaker could generate 'subroutine foo redefined' warnings . Reported by Ilya Martynov.
  • Fixed clear method for all Alzabo::ObjectCache::Store::* modules.
  • DEPRECATIONS:
  • The insert and update options for Alzabo::MethodMaker have been deprecated. They have been replaced by the new insert_hooks and update_hooks options, along with new select_hooks and delete_hooks options.
  • INCOMPATIBILITIES:
  • If you specify give the 'all' parameter to MethodMaker, 'insert' and 'update' are no longer included.
