[Openinteract-dev] ESPOPS-0.42 (Enhanced SPOPS)

[Ray Z. <rz...@co...>]

Here's the latest version of ESPOPS with a few minor changes.

	http://www.pserc.cornell.edu/ESPOPS/ESPOPS-0.42.tar.gz

ESPOPS stands for Enhanced SPOPS. Where standard SPOPS (or more
correctly, SPOPS::DBI) implements persistence for simple class of
objects whose data is stored in a single table, ESPOPS implements
persistence for a set of classes with inheritance relationships, where
the attributes are distributed across several tables, one for each class
in the inheritance hierarchy.

Our hope is that this functionality (not necessarily this code) will
eventually be included as part of the SPOPS distribution, along with the
new has-a and links-to functionality proposed on the openinteract-dev
list.

 From the Changes file ...

- Modified ESPOPS::DBI's create_table() and drop_table() to do nothing
   if $CONF and $TABLE_DEF are not defined. This allows a class to inherit
   from an ESPOPS class without adding a table. The Vehicle class is now
   an example of this.
- Turned off PrintError in DBI->connect in ESPOPS::DBI.pm
- Added RaiseError and AutoCommit to DBI->connect in ESPOPS::DBI.pm
- Modified global_datasource_handle() to make it try 10 times to connect
   before giving up.
- Removed SQL_BIGINT from list in _is_numeric_type() so it won't break
   with DBI-1.21
- Added test for cloning with false value in t/08_clone.t
