Changes for version 0.44

  • Bug fixes:
  • Bug fix in Alzabo::Runtime::Table->set_prefetch. Reported by Bob Gustafson.
  • Don't try to make directories when running Makefile.PL. Save it for later after user does 'make install'.
  • Fix handling of geometric types in Postgres (they were all being rejected as invalid).
  • Drop columns from a table before adding new ones. Sometimes this makes a difference. For example, if you are using MySQL and drop an existing AUTO_INCREMENT column and add a new one that is also AUTO_INCREMENT.
  • Only allow one sequenced column per table when using MySQL.
  • Doc fixes. Thanks to Ron Savage for pointing me towards some of these.
  • Fix a bug with the schema creator. If you attempted to make a change to a column with an extended type and you did not change the type, an error occurred.
  • Enhancements:
  • Schema creator now shows you a list of possible column types instead of having you type it in. However, for complex types like MySQL's ENUM or Postgres' POLYGON there is a text box to type it in.
