This is required because in certain instances it is important to lock
the object before retrieving it, otherwise if, for instance in
execution, we would need to fetch, lock and re-fetch to be sure we have
the latest object.
In moste of the Update*Commands this is not important as we perform a
list commit wins, where the client wants their version to be persisted.
Later a optimistic locking can be performed in that the given version
must be the latest, otherwise an exception would be thrown
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
We have three major blocks:
- In Execution Warning:
- STOPPED
- WARNING
- ERROR
- in execution:
- above including EXECUTION and EXECUTED
- in planning:
- PLANNING and PLANNED
- CREATED
- CLOSED
EXECUTION is used if any action is EXECUTED and a prior state exists
PLANNING is used if any action is PLANNED and PLANNING or CREATED
state exists
CLOSED is only used if everything is CLOSED, otherwise one of the
previous states is used
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
- New ParameterBagContainer interface for GroupedParameterizedElement
- StrolchRootElement extends ParameterBagContainer
- StrolchRootElement is now required in Queries, not StrolchElement
- New Version object on StrolchRootElement
You can now add policies to Resources, Orders and Activities:
<Policies>
<Policy Type="PlanningPolicy" Value="key:SimplePlanningPolicy" />
<Policy Type="ExecutionPolicy"
Value="java:li.strolch.policy.execution.TestSimulatedExecutionPolicy" />
<Policy Type="ConfirmationPolicy" Value="key:NoConfirmation" />
</Policies>
And now there is a PolicyHandler to get the Policy:
<Component>
<name>PolicyHandler</name>
<api>li.strolch.policy.PolicyHandler</api>
<impl>li.strolch.policy.DefaultPolicyHandler</impl>
<Properties>
<readPolicyFile>true</readPolicyFile>
<policyConfigFile>StrolchPolicies.xml</policyConfigFile>
</Properties>
</Component>
Which has its own configuration file:
<?xml version="1.0" encoding="UTF-8"?>
<StrolchPolicies>
<PolicyType Type="PlanningPolicy"
Api="li.strolch.policytest.TestPlanningPolicy">
<Policy Key="SimplePlanningPolicy"
Class="li.strolch.policytest.TestSimplePlanningPolicy" />
</PolicyType>
<PolicyType Type="ConfirmationPolicy"
Api="li.strolch.policytest.TestConfirmationPolicy">
<Policy Key="NoConfirmation"
Class="li.strolch.policytest.TestNoConfirmationPolicy" />
</PolicyType>
</StrolchPolicies>
Some tests are still broken at this state - will fix them in the next
commit
- Implemented PostgreSQL persistence
Still missing is the xml persistence implementation and fixing
the tests. Currently no tests were run, just trying to fix compile
errors
- 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
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.
Now if you add the DefaultServiceHandler property 'throwOnPrivilegeFail'
and set it to true, then the service handler will throw a
StrolchAccessDeniedException which in combination with the
StrolchRestfulExceptionMapper allows rest services to quickly determine
if the error was because the user does not have access to the requested
resource.
Same goes for performing queries in AbstractTransaction only there
instead of throwing a privilege exception, we now also throw a
StrolchAccessDeniedException
