- execption handling is done in the ComponentContainerStateHandler
- clients now not need to worry about exceptions which would make them
rethrow anyhow as a runtime exception
Now a SystemUserAction is defined as follows:
<Privilege name="ch.eitchnet.privilege.handler.SystemUserAction"
policy="DefaultPrivilege">
<Allow>li.strolch.agent.impl.StartRealms</Allow>
</Privilege>
elements is created programmatically and the time and values of the
changes is set by the programmmer. Note, that the persistence and xml
serialization is not implemented yet.
The version handling with code and data migrations was messed up. The
migration version was set after the data migration and then the code
migration used this value for further processing. Now there are two
attributes for the migration version (code and data). The files for the
data migration and the classes for the code migration have now
individual versions.
- now the currentVersions are queried later, because only after the
realm handler is started, can we query the current version.
- this lead to only parsing the migrations at initialize
- and thus in start querying the versions and performing the required
migrations
- If a code migration is run programmatically, then in some migrations
shouldn't fail if a realm is missing -> the realm might not be available
in a certain environment
- So sadly just auto closing a TX using try-resource from Java7 is a bad idea.
- Doing that leads to problems when an exception is thrown, then the close is called (duh) but this leads to commit being called.
- Since the Java language does not offer a decent way to detect if the close is being called in the context of an exception i was forced to add a tx.commitOnClose() and tx.rollbackOnClose().
- The default is that when a TX is opened, then the close strategy is rollback; the API user must call tx.commitOnClose() before the TX is closed by the braces, or as late as possible, to make sure that if an exception is thrown the transaction is rolled back, and not committed.
- The API was also extended with a tx.fail(msg):StrolchTransactionException so that if the implementor detects an unrecoverable error, one can write: throw tx.fail(“my reason”);
This was sadly an unavoidable late 1.0.0 change
