| 47 | 47 | This is the setup participant that will initialize the trac database and also the sample configuration provided with each trac instance, providing sane initial defaults for use with both an existing environment and a newly created one. For the creation of a new environment it uses [source:trunk/trac/db_default.py the default db structure]. and on upgrade it will use [source:trunk/trac/upgrades a db upgrade path] defined in the individual db*.py modules therein. The version number of the trac database schema is available from the ''system'' table, the key to look for is ''database_version.'' The value of this system property will be updated on environment upgrade. In addition to that, trac will also keep track of the initial database version that was installed when first creating the environment. The key to look for in the ''system'' table is ''initial_database_version''. |
