Should a command be undone, then some commands performed an undo,
although they didn't perform their work, this led to an inconsistent
data model. I.e. AddResourceCommand would fail because the resource
already existed and an undo would lead to the existing object being
removed
Once again it is clear how bad singletons are. One test killed the
timer, thus all other tests failed. Now the DelayedExecutionTimer is
retrieved from the ExecutionHandler and is called DelayedExecutionTimer
with a default implementation of SimpleDurationExecutionTimer
instantiated by the EventBasedExecutionHandler
Using the DurationExecution:
<Activity Id="produceBicycle" Name="Activity" Type="ToStock"
TimeOrdering="Series">
<ParameterBag Name="objectives" Id="Objectives" Type="Objectives">
<Parameter Name="Duration" Id="duration" Value="PT0.01S"
Type="Duration" />
</ParameterBag>
<Action Id="produce" Name="Produce" ResourceId="bicycle"
ResourceType="Product" Type="Produce" />
</Activity>
IActivityElement now has a new method .findParameter() to search up the
activity hierarchy to find the element
Simplified the API, removed the privileged user - now always use the
agent system user for running system actions. One method has no return
value and one has a return value. Now it is easy to perform a system
action using:
runAsAgent(ctx -> {
// do work
});
String result = runAsAgentWithResult(ctx -> {
// do work
return "done";
});
// execute a SystemAction
runAsAgent(action);
// execute a SystemActionWithResult
String result = runAsAgentWithResult(actionWithResult);

- built in User Challenge feature (currently only console)
- extended REST API to allow user to initiate a challenge and then use
the challenge to authenticate for a one time change password session
Now all root elements have a version, and if the realm has versioning
enabled, then actions through the ElementMap lead to new versions being
created. There are also methods to revert/undo changes to an object.
Some tests are still failing, this will be fixed later
So now users and roles are in their own files. This makes it far easier
to add new privileges without needing to take care if the user changed
their data.
- 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
- We have to re-think this. It does not work, throwing an exception if
commands are registered on a read-only TX as then we don't know if we
want to roll back or not - we probably need a ROLLBACK_ON_ERROR or
something, indicating that we are preparing a non-read-only TX.
- 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()
