- Creating new maps for transient, transactional and cached mode
- adding to Realms; including initialization
- adding new methods to transactions e.g. getActivityBy(), etc.
- Adding new ActivityDao with InMemory implementation
- extending PersistenceHandler
- fixed compile errors in the rest of the project
Still missing is the implementation in persistence handler and fixing
the tests. Currently no tests were run, just trying to fix compile
errors
- 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>
This can be very handy to not start the connection pool for realms which
you know won't connect to the DB (but is not transient) - weird isn't
it? =))
The property is: db.ignore.realm.<realmName>
The actual use case is the following:
- You have a realm which use is used normally and is not transient so
you have a configuration for it
- you have another StrolchComponent which opens its own transactions to
the DB but you only require a subset of the realms so you then use the
ignore property to ignore the other realms.
- currently the parsing of the versions is handled
- missing is the actual loading of the date into the realms
- and the performing of the code migrations
- and the registering of the performed migrations
- Now if you need to perform commands to carry on in your transaction,
you can simply use the tx.flush()-method.
- Should something go wrong, then even after a tx.flush() one can call
throw tx.fail("Reason") or tx.rollbackOnClose()
- 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

- this was a big issue as the query was delegated by the TX to the
persistence handler, which meant that the current element map types
(cached, transactional, etc.) were ignored. Move the doQuery to the
element maps, and this lead to also reimplementing the way the cached
element maps work: they now use an in memory dao, instead of MapOfMaps
